12:00 AM

But what I did not try was simply calling su in adb shell. wait...

ce4

that's perhaps not working

Izzy

Starting: Intent { cmp=com.android.phone/.InCallScreen }
java.lang.SecurityException: Permission Denial: starting Intent

(followed by stack trace)

t0mm13b

whoops!

Izzy

$ su
/system/bin/sh: su: not found

t0mm13b

adb shell am start -n com.android.phone/.EmergencyDialer

Izzy

12:03 AM

@t0mm13b to be more precise, the error was: java.lang.SecurityException: Permission Denial: starting Intent { flg=0x10000000 cmp=com.android.phone/.InCallScreen } from null (pid=8127, uid=2000) not exported from uid 1001

OK, I'll try the next :)

ce4

another Q: any 'added' binaries? stuff that's SUID, what's running as root (besides the normal daemons, vold, zygote, etc.)

Izzy

Yupp, success!

So what magic code did you want?

t0mm13b

#*#service#*#

ymmv

#*#service#*#

wait

why is it dropping the first asterisk!?

ymmv

ce4

escape sequence...

t0mm13b

ho right

*#*#service#*#*

Izzy

12:05 AM

LOL! Artificial intelligence: #*#7378423#*# is no emergency number...

t0mm13b

yay! :D

okie... let's try another

Izzy

But it looks to me as the #* sequence is wron, jus a mom...

ce4

Izzy: That won't really help, probably.

t0mm13b

adb shell am start -n com.android.phone/.OutgoingCallBroadcaster

Izzy

#*#7378423#*#

ce4

12:07 AM

Better try those 2 things: see if there's an unlocked fastboot

and b) see if the recovery gives you a root-console via adb

Izzy

That's what we wanted to figure out via some magic code. But b) might be a nice idea, I completely forgot about that.

ce4

Just try some reboot methods? Does the manual state the necessary button-shortcuts at boot?

Izzy

@t0mm13b fail (fc for broadcaster)

t0mm13b

hmmmm dang

Izzy

Manu...what?

t0mm13b

12:09 AM

rest of activities are "privileged"....

Izzy

Who ships manuals today?

I know however how to get to recovery.

t0mm13b

ooooh

try .ProcessOutgoingCallTest

the rest before that ^ remains the same

Izzy

Error: Activity class {com.android.phone/com.android.phone.ProcessOutgoingCallTest} does not exist.

t0mm13b

eeek... (was reading the jb source to the package...)

obviously stripped out

what's the command to launch via intent

could try this way

Izzy

In recovery now. Nice options: apply update from (adb|ext|cache), factory reset, wipe (cache|media) partition...

t0mm13b

12:12 AM

tel:*#*#7378423#*#*

use that as intent ... ?

Izzy

Let's see what adb has now. How to see if I'm having root? Right, let's look into /data/data

WTF!

$ adb shell
error: device not found

t0mm13b

are you doing that from adb shell itself

"Yo dog I heard adb shell don't like when you adb shell in so that I put in adb shell"?

as in

Izzy

nope, from my Linux machine. But just got another LOL:

lsusb

Bus 002 Device 017: ID 0525:a4a5 Netchip Technology, Inc. Linux-USB File Storage Gadget

t0mm13b

okie

permissions on linux itself?

Izzy

That must be the "Gadget" I guess. And I take it it needs some line in udev.

heh?

t0mm13b

12:15 AM

yup

Izzy

any idea what and where?

t0mm13b

0525 is the vendor, and a4a5 is the product id

do this: ls -l /etc/udev.d/rules.d/51-android.rules

if you have that file?

Izzy

Does one of you have an example line handy? Ah... No, no such file.

Yet.

t0mm13b

hmmm

Izzy

How does it look like?

t0mm13b

12:17 AM

SUBSYSTEMS=="usb", ATTRS{idVendor}=="19d2", ATTRS{idProduct}=="1354", MODE="0666" GROUP="androiddev", SYMLINK+="android%n"

replace 19d2 with 0525

Izzy

I try and adjust that line

t0mm13b

replace 1354 with a4a5

hummm do you have that group called androiddev?

I answered this identically the other day...

Izzy

Nope, not that I know of.

t0mm13b

0

A: fastboot not working on my Nexus 4

The clue lies with the comment above But I just tried 'adb reboot bootloader', and it worked. which shows that adb is indeed recognizing the USB connection, but not in fast-boot mode which is where this answer comes in... Sounds like the udev rule for the fast-boot is absent! Do this: lsusb wit...

my answer is in there :)

okie

might need to create a group

Izzy

Funny that it worked out-of-the-box when in normal mode...

t0mm13b

12:19 AM

Oo

must be one lying around in /usr/lib/udev/rules.d?

Izzy

empty directory.

t0mm13b

Oo

hummm what distro?

Izzy

Ubuntu

t0mm13b

hmmm try /lib/udev/rules.d

Izzy

hm, reloaded udev. Still no devices.

t0mm13b

12:23 AM

did you create the group and added yourself into the group?

Izzy

Yepp. But I guess I need a new login shell for that?

t0mm13b

(would need to log out and re-login again for the group id effect added)

mahhhnnn

ubuntu....

Izzy

Btw: that dir has a bunch of rule files. But no *android*

t0mm13b

(sorry, not intending a flame war, but....)

okie...

weird!

@ce4 how did that happen?

Izzy

Nah, no need for that. I'm f*cked enough with it. Today I would go for something else -- but that day I had no time to check...

t0mm13b

12:24 AM

lol

@Izzy aint we all f*cked in some way or another!!!!! :D lol

Izzy

Yeah... how the f*ck do I force ssh to use a login shell? Or does it do so by default? Still no devices listed.

t0mm13b

LOL!

Izzy

Ah, this way. Still, nope.

No devices listed.

t0mm13b

I remember there's a meta bout profanity... but f*ck that! LOL!

Izzy

LOL

t0mm13b

12:28 AM

(that was a joke!)

Izzy

Yeah, and I said LOL

XD

t0mm13b

:D :D :D

oh well... so are you beaten by this?

root/boot/unlock...

its awful, not right, manufacturers should give clear guidelines, "if you want to unlock boot-loader/root, please send me your serial number and email address and we'll disclaim any warranty null and void" if you tick here

I think that's how it should be ^^

when "registering" depending on how it is on their said website

would make life so much easier

Izzy

"Send me your serial" would be a joke in my case. Looks like Spaceballs: 1-2-3-4-5 XD

t0mm13b

LOL!

spaceballs

roflmfao

Izzy

Heck, so what. Before I screw up my workstation trying to root that damn tablet, I rather wait another 2 weeks and get a rooted one by mail.

Yeah, love Perry Air!

t0mm13b

12:33 AM

lol!

Izzy

And while just talking about screwing up -- no, I'm not the president XD

(President Screw was it, right?)

t0mm13b

LOL! and when you do get it, rip the f*ck out of it i.e. rom dump it, you might be able to post it up and let others flash it?

Izzy

Not publically, no. But if you help me, for educational purposes, to dump it... You need to verify my work, maybe?

t0mm13b

wouldn't that circumvent the whole shenanigan?

sure

can do that ;)

Izzy

OK, no promises yet, before I got my hands on one of them.

t0mm13b

12:36 AM

take your time bud :)

Izzy

Guess I boot back to normal mode now. Who knows, in the end they don't even have ADB running in recovery.

t0mm13b

sucks!

Izzy

Just thinking aloud: It has an option "apply update from ADB". What can I break if I hit that?

t0mm13b

apply update from adb?

interesting...

well...

its cwm based recovery right?

Izzy

I'd say nothing, as long as there's nothing sent from the other side which it can apply, right?

t0mm13b

12:37 AM

if so

Izzy

I don't think so -- or they just ripped the most interesting parts off (Nandroid etc).

t0mm13b

then yes, its possible to put in an "update" zip that can install su binary/busybox/superuser.apk

Izzy

But they might add "wipe Dalvik" in one of the next versions, hopefully...

I do have those binaries here. But how would I make an update.zip of them?

Just zip them up with the correct directory structure?

t0mm13b

yes

and the updater-script would need to be inserted to tell it to place the files into their respective directories

Izzy

That's all? C00l. I could try that. What needs to go where? Ah... There we are again, another part I never saw...

t0mm13b

12:41 AM

ok... no worries there, hummm... take any ota update zip you can find...

does not matter what device

can rip from that

the updater-script that is

and just trim it out with su, superuser, and busybox

Izzy

I have no update.zip here. Never applied any.

t0mm13b

even, any cm zip you can find

does not matter what device, you can unzip it

Izzy

Oh, lyer! I found one. Wait...

So what do I need? META-INF/com/google/android/updater.sh?

sorry, updater-script?

t0mm13b

yes

you also need the META-INF subdirectories

Izzy

Something else?

Sure, done.

t0mm13b

12:45 AM

okie, hummm...

Izzy

The entire path plus the one file.

t0mm13b

say your working directory is called Izzy_ROOT_BOOT for exampel

and inside that directory you have Izzy_ROOT_BOOT/META-INF/... ok?

you create a directory called Izzy_ROOT_BOOT/system <-

also create a directory called Izzy_ROOT_BOOT/xbin

Izzy

done

busybox + su to xbin, right?

t0mm13b

this is top of my head,

yes

might need to move xbin into system/xbin

checking

Izzy

SuperUser.apk to system/app

sec

t0mm13b

12:48 AM

yeah...

so really, there should be Izzy_ROOT_BOOT directory and underneath that

Izzy_ROOT_BOOT/system/xbin

Izzy_ROOT_BOOT/system/app

Izzy

system/xbin, right

t0mm13b

Izzy_ROOT_BOOT/META-INF/....

yeah

does this make sense so far?

Izzy

Does the version matter, or are they all compatible? I just took the binaries from bin4ry's kit.

But it looks like I have newer ones from my Moto Milestone²

t0mm13b

as long as su/superuser matches up - you should be ok

i.e. taking it from one kit exclusively is ok

Izzy

yeah, better that.

t0mm13b

12:52 AM

right, so there should be updater-binary, updater-script in the META-INF/com/... directory

Izzy

Now for the script.

Oh -- that binary is also needed?

t0mm13b

okie for the script... tricky.... hummm

yes, that is the "interpreter" for the updater-script

it reads in each line from it and performs the copy operation etc to the actual system partitions

Izzy

OK, copy'd

t0mm13b

right... updater-script....

lemme look

Izzy

package_extract_file("sbin/recovery", "/sbin/recovery"); => this syntax seems to be good to copy the stuff to the target.

Sec, wife calls...

t0mm13b

12:54 AM

okie

Izzy

back.

So how about
package_extract_file("system/xbin/su","/system/xbin/su");

etc?

ce4

@izzy what did you ask?

(You called me)

t0mm13b

pastebin.com/yxqtuVHG

That I think should be sufficient enough as updater-script

brb

Izzy

@ce4 when? Lost the line...

ce4

Nevermind.... Nighty night!

Izzy

1:03 AM

Yepp, sleep tight... ahm, well :)

ce4

@t0mm13b <here

Was tomm really. Gute nacht dann...

Izzy

@t0mm13b Nice one! Copied it over, zipped up the folder. Now trying to switch that "apply update.zip from adb" on...

Fail. Epic fail!

I wish I could send you a screenshot.

"failed to open driver control: No such file or directory"
Now send the package via "adb sideload..."

Very funny. Of course, no devices show up.

t0mm13b

hummm... that zip, right

did you zip it inside Izzy_ROOT_BOOT?

Izzy

Doesn't matter. If ADB cannot see the device, it won't sideload.

t0mm13b

Oo

no sdcard?

Izzy

1:07 AM

Sure, "relative root"

t0mm13b

good, you need to sign the zip

Izzy

Yeah, And now the mini-boot-hole...

Because I cannot get out of the waiting for zip mode...

t0mm13b

the only thing that could go against you is this

Izzy

Oh, sign? How that?

t0mm13b

testsign.jar

you need to run that

java -classpath testsign.jar -class testsign original_zip.zip signed_original_zip.zip

that is if you have jdk present :-\

Izzy

1:09 AM

Where from do I get that?

JDK yes, if 6 is enough?

t0mm13b

code.google.com/p/zen-droid/downloads/…

Izzy

Unrecognized option: -class

t0mm13b

one sec... memory a bit shot!

Izzy

Heck, does this really require the Oracle Java stuff?

t0mm13b

java -classpath testsign.jar testsign original_zip.zip signed_original_zip.zip

the -class in my previous was wrong my bad!

Izzy

1:13 AM

Yupp, that worked.

t0mm13b

coolio

can you put that signed_original_zip.zip onto sdcard and get recovery to try flash it?

Izzy

Will try that now.

t0mm13b

okie

fingers crossed

the only thing I can say is this that could work against you

1) ramdisk's default.prop would have ro.adb.secure=1 (meaning its secure, if it was 0, its insecure, so could su from within adb shell) and 2) MTD partitions, is that present on the tablet or some proprietary /emmc/ thingy?

worst outcome, you'll have superuser.apk in the /system/app directory and will show up on the drawer but no su

Izzy

Bonga. They verify the package -- and it failed :(

t0mm13b

bummer....

:(

looks like recovery is rigged up

Izzy

1:18 AM

Andy says so as well: Lying on its belly, back open, and a red exclamation mark looking out. Well, they've got humor...

t0mm13b

sh!t

that's some lock-down!

Izzy

Yepp. We did our best, but it wasn't good enough...

But it was worth it! At least we do know by now what is not working...

t0mm13b

yep :)

unfortunately...

ha! probably tabby cat are in frantic panic as in "da f*ck do I root the thing?" meeoooow!

Izzy

If you happen to have another nice idea: I'm open for it. As said, the device is going to be returned either -- and they know that I'd look for this :)

t0mm13b

"WE need it for Izzy... .panic .... red alert...."

Izzy

1:21 AM

LOL!!!

t0mm13b

"DDWEEEEP, .... DDDWEEEEP.... DDDWEEEEEP"

red lights flashing all over the place

cue ST:TNG in battle mode!

Izzy

Just one, and it looks almost dead (on Andy's back)...

t0mm13b

"Alas poor Andy, I knew thee well"

lol

Izzy

Meow... Looks like we should go sleep, before those guys in uniform come with their guns and ask what we've smoked -- and one of us says "Shit..."

t0mm13b

lol

yeah, sleep is right :)

Izzy

1:23 AM

Yupp. Thanks a lot for staying with me!

t0mm13b

will chat you later on anyway :)

no problem at all

anything I can do :)

Izzy

I send Andy through now (just wanna see if it still boots up and turns up on ADB)...

t0mm13b

heh

Andy: The Resurrection

lol

Izzy

Looks good so far... passed the logo... now the... ah! there we are.

t0mm13b

yay! thank f*ck for the script, it was not destructive at least xD

(no profanity, me bad boy!)

Izzy

1:27 AM

Nah, looked really nice! And ADB is back up and running. Just had to pluck the line after boot, and connect it again -- didn't come up with the plug in.

As somebody said: "Plug-n-Play only works for 50%. To be more precise, the 'plug' part always works..."

t0mm13b

LOL!

Izzy

Yeah. So we say: Bug and pray...

Or was it "Plug and pray"?

Or f*ck and say?

t0mm13b

LOL!

Izzy

OK, nuff. 2:30am, my wife's going to kill me... Thanks again for your support! Guess we only failed on the signature. Whenever you get another idea, we can try that -- as long as the "broken device" is still with me.

t0mm13b

no worries at all :)

Izzy

1:30 AM

But for today: Good night, sir!

t0mm13b

now off to bed you ;)

:D

Goodnight sir! :)

catch you later :)

Izzy

Yepp!

t0mm13b

Liam W

9:38 AM

I really wish people wouldn't delete things that gain me rep :veryangryface:

ce4

10:42 AM

@LiamW what happened?

Liam W

@ce4 I posted an answer to a question. It got 2 upvotes, the question got deleted. If none of the questions/answers I answered/posted got deleted, I would probably be at 4,700 rep by now...

I'm thinking of getting a Nexus 7 - is that a good choice? It's my birthday on Monday ;)

ce4

Yep, right now typing on one.

Liam W

Is it good?

ce4

@LiamW: Yeah, pretty neat. I first thought I'll be missing some things, but eventually I'm not.

Features not present: HDMi, SDcard slot

Liam W

Can't you just use a MicroUSB->HDMI adapter? Or would that not work? I wouldn't use it anyway ;)

And 32GB is more than enough for me!

ce4

10:56 AM

Nope, no HDMi

Liam W

Why do you put the i lowercase? It should be all uppercase...

HDMI -> High Definition Multimedia Interface

ce4

What I especially like: Clean Android (pure Google), superb hackability (it's unlockable and enjoys good community support), nice price

Lol, typo (HDMI)

Liam W

The price is the best part ;) Also the fact that the bootloader is easily unlocked, and it has super good community support...

ce4

Yep. And it's one of the most secure devices around

Liam W

Is it easy to root do u know?

@ce4 How?

ce4

10:58 AM

Yes. You only have to do a 'fastboot oem unlock'

Liam W

Yay :) Lets just hope I get enough birthday money then...

ce4

as for security: It has a locked BL, you can unlock/relock it (and it wipes the device if you unlock)

Liam W

Everywhere is sold out of the cheaper 16GB ones, except Tesco (a supermarket) but it costs £20 more there, and it would be better just to get the 32GB one for £199.

Hang on, will be back later (going to reboot to complete Ubuntu install)

ce4

Yep. Get that 32GB one (if it's only a mere difference of 30)

@LiamW Lol. reinstall? or 1st install?

Liam W

@ce4 First install on this laptop, with WUBI

It has no CD Drive so there isn't another way ;)

ce4

11:05 AM

Wait.

Do you just want to try it out or do you want to really install it and get rid of windows?

@LiamW ^^

Wubi is only good for trying out Ubuntu without really installing it. (I.e. the Windows stays there and Ubuntu runs from a disk image file on the Windows partition only)

It's pretty cool though. You can reboot to Windows and uninstall the Wubi app and all is gone

Liam W

I actually want both, as I regularly use windows programs.

But some things I want to do need linux

ce4

Thing is: All the Ubuntu data will reside on your NTFS partition

But: Just try it out, if it works, =>fine

And it's absolutely no stress to get rid of it without having Windows problems afterwards...

Liam W

11:24 AM

On my old computer I installed it to a separate partition and I ended up removing the MBR...

ce4

Yeah. Known problems. I solved that stuff long ago by giving Windows the boot.

=> Boot problems solved :-)

My windows instances only run virtually now (once in every few weeks or months)

ce4

@LiamW: as for your rant on deleted/closed questions: It's often worth to rephrase bad q's

Ex. android.stackexchange.com/posts/37443/revisions

This one got a vote close before and one -1, after my adit it received three +1's

Flow

Good example @ce4

If the question you intent to answer lacks quality, edit it first (if possible) to reduce the probability that it get closed

ce4

Yeah, I saw the vote-close and thought that it was in fact a good Q, but only phrased to localized.

Flow

Generalizing a question, just like ce4 did in android.stackexchange.com/posts/37443/revisions, is a great way to improve the site's content

ce4

Was very surprised by the turnaround after my edit

Q: How Do I Get Back My LG LTE Download Folder Back?

So Yesterday I Was Putting Music On My Phone. Its An LG LTE "CoolPad". I Whent In My Downloads Folder And I Deleted Every Single Thing In Downloads. Then I Noticed That I Couldn't Use My Internet. Nor Could I Download Any More Pics. or Recieve Them. Please Help Me.

One of the most confusing questions I've ever read

ce4

3:18 PM

yep

ce4

4:03 PM

@Flow: As for that weird question: It's a) language barrier and b) seemingly a not too tech-versed user
I gave in and commented, let's see if he comes back. If not => delete
