You can dl recent i9100 CM10.1 firmwares here: get.cm/?device=i9100

dmsg -c gives me
`[63902.028114] usb 2-4: USB disconnect, device number 69`
`[63905.664081] usb 2-4: new high-speed USB device number 70 using ehci_hcd`

ce4

The .zip also contains a boot.img

Oh @Pureferret looks promising

Does the 5.5. version have the option to start 'adbd' on demand under advanced?

Pureferret

lsusb | grep Samsung
Bus 002 Device 070: ID 04e8:6860 Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II]

Let me reboot and see

ce4

what about 'adb devices' ?

Pureferret

nuthin'

adbd=running and adbd.recovery=1

ce4

9:05 PM

root 25760 0.0 0.0 30392 1444 pts/19 Sl+ 20:42 0:02 adb fork-server server

is your adb process running as root (the 'fork-server' daemon )

Liam W

I was going to say that ce4!

ce4

:-)

Liam W

Have you seen the new chat room I made?

ce4

which one?

Liam W

The only other active one funnily enough.

Pureferret

9:06 PM

devices [-l] - list all connected devices
('-l' will also list device qualifiers)

using -l makes it show up as a recovery usb

0019638048f28e recovery usb:2-4

ce4

good

but you cannot connect with 'adb shell', can you?

Pureferret

YES!

Woot

Liam W

YAY

Pureferret

how I can exit that and I can run your command?

there is also a adb backup command...

Liam W

use the exit command to get out of adb shell

ce4

9:08 PM

fine.

I'll post that command again, wait

Liam W

adb backup is only for normal user mode

Pureferret

how I can exit that and I can run your command?

ce4

one sec

'exit'

done?

If you like, you can install 'clpbar'

it's a pipe throughput visualizer

Oh: And mount USB storage should now also work

@Pureferret ^^

for i in mmcblk0p{1..12} mmcblk1p{1,2}; do adb shell cat /dev/block/$i \| gzip -1 \| uuencode o | uudecode -o - | gzip -d > /targetfolder/$i.img;done

this fetches everything

but it's slow. You can also use Mount USB and omit the big 12GB usb partition via adb

Pureferret

9:26 PM

@ce4 I like this option

I've mounted it but I've not seen it pop up in my explorer

ce4

?

Should've done so a few sec's later

maybe you need to manually do it (see by "cat /proc/partitions")

Besides this: Which option do you want to take? Go CyanogenMod? Not sure how to fix your actual situation (so that you have root and retain your current setup)

Pureferret

@ce4 it doesn't seem to show up there

ce4

Which option?

Pureferret

hang on, sorry

ce4

ah, in your partitions list, ok

Pureferret

9:37 PM

11 0 1048575 sr0
11 1 7973664 sr1
8 0 976762584 sda
8 1 102400 sda1

8 4 698532864 sda4
8 5 102400000 sda5
8 6 11883520 sda6

no idea how I know which is which

ce4

none

sr* = CDrom or so, sda is your primary HDD

Pureferret

@ce4 and lsusb doesn't show it up either

ce4

should be something like sdb + sdb1

but you could get in via adb, right?

Pureferret

I could

I thnk whilst mounted I can't do that anymore

ce4

maybe, but should be possible normally

Pureferret

9:40 PM

hmmm

yeah shell is saying device not found

ce4

lsusb?

ce4

completely missing

Pureferret

yup

ce4

anyway, then just use adb to pull the data

for i in mmcblk0p{1..12} mmcblk1p{1,2}; do echo $i; adb shell cat /dev/block/$i \| gzip -1 \| uuencode o | uudecode -o - | gzip -d | bar > /tmp/$i.img;done

Pureferret

9:43 PM

adb doesn't seem to work

getting it back now hopefully

ce4

yeah, reboot the CWM

Pureferret

ok

it's gone now

rats

ce4

?

adb mode inaccessible?

just try to replug it again

Pureferret

yeah

ok

ce4

I have these issues too

(I just updated my S2 via this method)

Pureferret

9:48 PM

uh-huh

still trying

ce4

at least it once worked

Pureferret

yeah

we can do this, we have the technology

ce4

:-)

I noticed that plugging the micro-port does the trick (only happens with my S2 though, must be a samsung thing)

(i.e. the phone-plug, not the PC-side)

Pureferret

I have sudo dmesg running on a 1 second watch and just playing with the usb cable now

in and out

ce4

hmm, really strange

always the error -22?

Pureferret

9:56 PM

@ce4 for?

ce4

(that got logged in your dmesg which you posted above some time ago)

or does dmesg output nothing at all when you replug it?

Pureferret

@ce4 nothing

even with the -l option

ce4

CWM's up? and nothing happens when plugging in? What if you boot your phone when it's plugged in already?

Or remember what you did special when it worked the last time?

Pureferret

@ce4 last time was just the first boot into CWM from the new flash

ce4

that should be no reason (booting the recovery doesn't change anything. all is mounted read-only by default)

Pureferret

10:04 PM

weird

I decided that trying 'fix permissions' would be a good plan

it's still 'fixing'

ce4

erm, ...

Pureferret

yeah I'm regrettign that now as it's taking too long

ce4

That modifies your firmware, it's going over all of your files probably

never actually did that personally

Pureferret

yeah....

done!

well I can go into the actual device now

so I might try using adb not in CWM mode?

is that possible?

ce4

fine

yeah

do you have that command:

bar

Pureferret

10:12 PM

adb bar?

ce4

no on your linux box, just "bar"

it's in the "bar" package in ubuntu

Pureferret

no

ce4

If you like you can install it

Pureferret

...what does it do?

ce4

gives you an ETA (visualizes pipe throughput)

it's just eye candy

sort of (if one can say that on the cmdline)

Pureferret

10:14 PM

awesome

ce4

@ce4 <= here's the command

Pureferret

thanks

ce4

To make a dump of your S2's partitions

Pureferret

Yup

I'm just booting back into CWM

nope

it won't have it >.<

ce4

didn't you just have adb access?

Pureferret

10:22 PM

Yeah

not anymore

ce4

Why did you reboot then?

Pureferret

oh no

I lost it before I rebotted

I tried to mount my device, remember? Then it wouldn't let me adb anymore

ce4

Ah, I thought it worked after the 'fix perms' thing

Pureferret

ah no

13 mins ago, by Pureferret

well I can go into the actual device now

that means I can turn it own as usual

ce4

Ah! the kernel now works again...

Now i got it

Pureferret

10:26 PM

@ce4 yes

ce4

However your device now doesn't have the right kernel fitting for your rom

Pureferret

can I just leave it at that?

I don't know how flashing CWM 5.5.0.4 did that

ce4

(the kernel is old) your firmware is newer. Very probably stuff doesn't work (camera, mic, taking/watching videos)

It flashes the boot-kernel

(that is in fact an original Samsung kernel)

just an old one with addons to have the recovery working

Pureferret

ahhh ok

ce4

Now you got a working device back: Which exact version is it running (samsung firmware)?

Pureferret

10:28 PM

that's in settings right?

ce4

yeah, settings=>device info or so

Pureferret

3.0.15-TH codeworkx@cyanogenmod #2 SMP PREEMPT Sun Apr 29 10:50:20 CEST 2012

ce4

ah, that is a cyanogenmod kernel. Do you know what was installed before that?

forum.xda-developers.com/showthread.php?t=1103399

It says so here (to pick the right download)

Pureferret

that one----> CF-Root-SGS2_XX_OXA_LPH-v5.2-CWM5.zip <---that one

ce4

@Pureferret Thats what you said you loaded

Pureferret

10:33 PM

yeah

ce4

It did match your then installed stock version, right?

Pureferret

yes

I checked my kernel before I tried to flash it

ce4

Something must have gone wrong...

Pureferret

yeah...

I gathered XD

ce4

you don't have a encrypted phone, do you?

check this: forum.xda-developers.com/showthread.php?t=2050297

A very recent root-exploit that works for your device...

You can then do a titanium backup and decide how to proceed

If you like, there's even JellyBean 4.2 (Cyanogenmod available)

@Pureferret ^^

Pureferret

10:37 PM

@ce4 no, not encrypted

ce4

ok, the original cfroot source states problems with crypto

(just saying)

Pureferret

@ce4 well not as far as I know

I've not encrypted

ce4

you have to do it manually in the settings

Pureferret

ahh ok

I've not

ce4

@ce4 here's a working exploit

Pureferret

10:41 PM

cool

I'm reading it now

ce4

In fact this hole is very uncool (of Samsung), because any app can exploit it, easily. Good for modding though

Pureferret

@ce4 I don't quite get what it does

ce4

nevermind, it's just a root-exploit to gain root-access and install Superuser+su

Pureferret

ah ok

why not just flash it with the JB you mentioned??

ce4

(the hole that's exploited opens the whole system RAM read/write for anyone. The exploit uses it to overwrite system memory and gain access)

The JB needs a wipe in advance

Which you probably don't want (not having a backup yet)

Pureferret

10:45 PM

@ce4 right

and the CW 5.5 doesn't give me root to use titanium, does it?

ce4

it's just a recovery (linux + a basic gui). Titanium needs a full fledged android

Pureferret

@ce4 got you

so I want to root it first....and the exploit is a good way

ce4

It allows to do backups (but that needed too much space you said)

Pureferret

right.

ce4

Yep, that root is OK

Pureferret

10:51 PM

@ce4 that root being a .apk?

ce4

yes, for easy deployment

Pureferret

cool

ce4

You need to enable 'unknown sources' in the settings

Pureferret

I just installed it via the QR code

and it says it's already rooted

so the next stpe is to download titanium from the gPlay?

ce4

sure

Pureferret

10:57 PM

Thanks for doing this by the way

extremely helpful

ce4

:-)

I have some time left (waiting for stuff to compile)

switching between chat here and reddit...

Only thing is: Hands on in RL whould've been way faster (than remote via chat), well.

Pureferret

but I'd have learnt less

ce4

sure.

I once had to secure a friend's Nexus that got its screen shattered to pieces

got him all valuable data in an hour and got his Nexus S for that action :-)

Most valued item: Phone Number of a gal he met in one of his notes... :-)

Pureferret

@ce4 Heh

backing up now

ce4

What to do after that? Going the CyanogenMod route? Or do you want to leave it in this current state?

Pureferret

11:05 PM

@ce4 I'd just like the standard Samsung ROM but rooted

ce4

You'd need to find a fitting kernel then (the one you replace by installing CFroot)

PS: CM has some cool features. If you had an Galaxy S i9000, I'd say go for it.

Pureferret

@ce4 CM=CyanogenMod?

ce4

the i9100 is not so well supported because Samsung chose to not help the community

yep (@CM)

Pureferret

@ce4 ??

ce4

i.e. the i9100 port lacks some stuff (no FM, HDMI, amongst other minor things)

plus.google.com/101093310520661581786/posts/cdPnNjLAb4F?hl=de

That's one of Cyanogenmod's former Samsung GAlaxy maintainers

Pureferret

11:09 PM

@ce4 Ahhh

ce4

He and others ran to Sony. Nice but very lengthy read (8 posts over the course of 8 weeks or so)

As for Samsung: I can't stand their touchwiz, once I've seen Android's original UI (on a Nexus or so)

Pureferret

touchwiz?

ce4

That's Samsung's graphical user interface (which is a proprietary Android addon)

Pureferret

@ce4 Ah ok

can't stand to dev with or use?

ce4

only for using it. It feels awkwardly ancient compared to the new JellyBean UI

Maybe I'm overrating it, take it with a grain of salt. :-)

forum.xda-developers.com/showthread.php?t=1075278

here are some original kernels ^^

Not sure, how to properly revert to your old setup

Try things like camera, usb-storage, photographing, etc. And see if all works or somethings broken

Pureferret

11:18 PM

@ce4 with each new flash?

ce4

no, with your current setup

to decide if you leave it the way it is

Pureferret

@ce4 ah ok

the camera works but I can't see whats on the screen atm

ce4

yeah. What I suspected

Either: Find the correct matching kernel for your actual firmware again and hope it flashes well

Or: Go for a custom firmware like CyanogenMod. Also nice.

Pureferret

@ce4 I may go for the later

ce4

Or as a third option: Live with those broken features until Samsung releases another upgrade

Pureferret

11:24 PM

how does CM compare to vanilla?

ce4

Added value, same experience

It's rooted, you can overclock and do more stuff

in comparison on a Nexus: CM gives you a nicer shell and a more hacker friendly root-installation amongst others

Pureferret

@ce4 Look-and-feel?

ce4

like a nexus

it's consistent across all of their supported devices

Pureferret

so it looks the same?

ce4

youtube.com/…

here are some impressions

Pureferret

11:30 PM

cool

ce4

If you install it you need to install 3 .zip files and then do a wipe before initially booting

Pureferret

I may do that

ce4

in case you decide to do it, you need:
- CM10.1 .zip firmware file from http://get.cm/?device=i9100
- GApps 4.2 Google package from http://goo.im/gapps
- Radio update XXLS6 http://obihoernchen.net/downloads/SGS2%20Modems/Modem_XXLS6-CWM.zip

@Pureferret: consult your pillow... :-)

Pureferret

@ce4 Not known to be a good android modder

ce4

You think you'll be to fearful tomorrow?

Pureferret

11:40 PM

@ce4 Nah

I laugh in the face of fear, and drop icecubes down the vest of death

ce4

Yeah, that's Android's update problem and the lock it down or don't commit to the community attitude of device makers

It's a mess and you constantly have to keep track in the jungle of xda to not forget anything
