Let him first do a backup, then comes all else

@Pureferret: OK, that's better (the info)

Pureferret

...link doesn't work....

how do you suggest I back up?

I never got Kies to work either on my windows boot

ce4

Boot into CWM (ClockworkModRecovery), then 'backup'

Pureferret

not enough space

I already tried once but it must have filled it up

ce4

another SD card, maybe?

Pureferret

I don't have one

no shops would be open at this hour

ce4

6:53 PM

That's a showstopper then

Pureferret

is there anything I could install (windows or linux) that would just read my phone as a mass storage unit?

ce4

until you get one

Pureferret

@ce4 ouch

ce4

yeah, but that is complicated

(the mass storage stuff)

is CWM running?

let's try it

Pureferret

@ce4 I can handle complicated, hopefully

@ce4 yes

ce4

6:54 PM

fine

you need : uuencode (ubuntu/deb: sharutils package)

Go through the partitions one by one, then. Just pulling them using adb (it's a little complicated though) And sloooow.

one sec

(trying this on my s2)

Pureferret

ok, I'm downloading the sharutils package

do I just run uuencode form the terminal?

ce4

nope, wait

.. testing the command

here's the partition list: cat /proc/partitions

need to deduce later on which is for what

Pureferret

got you

ce4

To backup, you'll have to 'cat' it through adb, as pull doesn't work

BUT...

Pureferret

dun dun dun

ce4

6:59 PM

adb's terminal (sucks and) inserts CarriageReturns, that's why you need to 'protect' the data using uuencode before

Pureferret

got you

what is adb?

ok cool

ce4

adb shell cat /dev/block/mmcblk0p1 \| gzip -1 \| uuencode o | uudecode -o - | gzip -d > mmcblk0p1.img

it's the adb debugging bridge for android, part of the sdk.

It gives you various commands, amongst them 'adb shell' let's you hop onto the device and get a console

You probably need to download the SDK (if you're new to this)

adb is part of the platform-tools package in the Android-SDK

Pureferret

sudo apt-get install Android-SDK ?

ce4

nope, it's propriertary and not part of any distro

Pureferret

@ce4 then how do I get it?

ce4

7:03 PM

developer.android.com/sdk/installing/index.html

@Pureferret ^^

Pureferret

@ce4 downloading

ce4

Alas, the SDK is a little big, adb is a tiny part of it and standalone, but it's the safest way to get a proper binary

(Not suggesting filestube or xda)

Pureferret

@ce4 fair point

ce4

Maybe you'll find future use for having the SDK installed :-)

Pureferret

@ce4 I think I will

I have some ideas for apps I'd like to code

ce4

7:11 PM

Once you've finished, here's the whole backup code:

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

That's my backup script for my S2, btw

Pureferret

and that backs up just my phone or .... all my partitions?

ce4

Yep, all

Wait a sec, here's the partition listing:

There's one problem: IT's slow as ...

You can later try a 'file mmc*' to find out, what is ext4 (and what binary)

Pureferret

@ce4 so..uh, how is it going to back up the data on my other partitions which are much larger...? Am I not getting something?

ce4

The same way

Pureferret

@ce4 sure, but.... I don't have space on my HDD to back up everything on my HDD

if that makes sense?

ce4

7:18 PM

:-) OK

You probably don't have to backup the big sdcard partition

mmcblk1p2

Pureferret

@ce4 how is that ok? Won't it get to my 'data' one, fill up my HDD and then fail over?

ce4

A wipe doesn't delete the sdcard partition

Only the data partition

and I think stuff in the /efs partition as well (e.g. encryption keys)

Pureferret

sure, I'm not worried about that, that's like 16 gb? I thought as this went over all of my mounts/partitions on my PC, one of which is my phone?

ce4

:-)

you have the 16GB model?

to clarify:

it does a loop over all your phone's partitions, which sum up to 16GB

Pureferret

@ce4 also, off your last link I downloaded this: developer.android.com/sdk/index.html#ExistingIDE

@ce4 AH!

Not my HDD partitions

or some such

ce4

7:21 PM

Of course not

Pureferret

Right

I was getting a tad confused

ce4

it's sort of like scp'ing remote data to your local pc

Pureferret

@ce4 sweet

ce4

adb shell gives you a shell and you can see the output of commands you execute

Pureferret

ok cool

ce4

7:22 PM

so: adb shell cat $partition outputs partition data

Pureferret

so I downloaded the Android SDK, which is now a folder on my PC

ce4

but before it does so it, there's gzip+uuencode

fire up 'android'

it's in ./android-sdk/tools/android

Then install platform-tools

Pureferret

@ce4 already have it

ce4

ok, the 'adb' binary is in android-sdk/platform-tools/adb

Pureferret

@ce4 cool....

how do I use it?

ce4

7:26 PM

it needs proper usb access rights, so either adjust udev or run it as root

try an "adb devices"

(adb is in my path, so 'adb' works for me)

Pureferret

How do I add it to my path?

or add platform tools to my path?

ce4

i symlinked it to /usr/local/bin

but you just can go to that folder or copy it over

Pureferret

ln -s <platform-tools> /usr/local/bin ?

ce4

yep

erm, nope

ln -s 'bla/platform-tools/adb' /usr/local/bin/adb

(i.e. only link the single binary, not the folder)

Pureferret

@ce4 got you

ce4

7:33 PM

ready?

try "adb shell" or "adb devices"

Pureferret

@ce4 I am, my machine is slowing down atm

ce4

If you have a shell or see output like '0009d7fc073573 device', it's working

Pureferret

command not found

sudo ln -s '/home/craig/Android\ Dev/sdk/platform-tools/adb' /usr/bin/adb

ce4

nevermind, fix that later

just cd to the platform-tools and run from there using "./adb"

Pureferret

@ce4 ok

ce4

7:38 PM

ah, have you installed the 'platform-tools' package for the SDK, already?

Pureferret

installed? No

ce4

ah, fire up ./tools/android before and install it

Pureferret

Hmm, it says it's installed

`* daemon not running. starting it now on port 5037 *`
`* daemon started successfully *`
`List of devices attached`
But no devices

ce4

do you run it as root?

(if not kill the daemon again and restart)

(adb kill-server)

Then: Connect your S2 and start CWM

You should see it then

Pureferret

nope I can't see it, even as root (sudo will do won't it?)

ce4

7:44 PM

yep

S2 is connected and running CWM?

Pureferret

yes

ce4

Try replugging the micro-usb port on the device end

Pureferret

@ce4 nope

ce4

CWM looks something like this?: pcgerms.com/wp-content/uploads/2012/12/…

Pureferret

yeah

what does it do?

ce4

7:47 PM

it's the recovery system. It offers the adb functionality we want to use now

It's basically a fork of the original recovery with addons

Pureferret

@ce4 yes...

were you showing me the menu, or that menu item?

ce4

try a few more times to replug (slowly)

Known issue

Bus 001 Device 116: ID 04e8:6860 Samsung Electronics Co., Ltd

BTW: This should be visible via "lsusb"

Pureferret

nope

:(

ce4

What version of CWM is installed, ?

Pureferret

5.0.2.7

ce4

7:54 PM

I have: 6.0.2.7

ok

Need to first fix that connectivity problem

there's no kernel message, anything?

dmesg -c , then replug, dmesg?

[3494527.692772] usb 1-2.2.1: new high speed USB device number 117 using ehci_hcd

This is what dmesg gives me when I plug it in

Pureferret

[60156.524088] usb 2-4: new high-speed USB device number 54 using ehci_hcd
[60156.656842] usb 2-4: no configurations

[60157.208414] usb 2-4: device descriptor read/8, error -71

ce4

ok

replug it, Sloooooowly

Pureferret

Ok...I tired

ce4

better?

we had that recently already, seems like the connection needs to settle before it can be polled by your linux

Pureferret

no, not better....

can I force it to poll?

ce4

7:59 PM

not sure

maybe restart to CWM when plugged in

Pureferret

when I run it, it just spits out that text, are you expecting it to keep running and display new devices?

ce4

@ce4 <= nope, just the single line, that i posted above

Pureferret

@ce4 no it doesn't do that

I selected the rboot option from the CWN menue

ce4

yep, you get those errors, strange

Pureferret

should I go back to the CWM menu and running that command again?

ce4

8:03 PM

hmm

Pureferret

AHA!

ce4

?

Pureferret

If I'm no in the CWM menu, I get that line

just tried it now

ce4

the regular boot?

Pureferret

no...when I select 'reboot' it goes into 'black screen mode' as though it's off

which it may be for all I know

ce4

8:05 PM

ah, the broken normal system

and you don't have CWM 6.0.2.7 but only 5.0.2.7?

Pureferret

the 5 version

ce4

ok, is there an option to enable adb in under advanced?

My CWM automatically starts it

former versions didn't

Pureferret

Ahh ok

let me boot into it and see

I have:
`Boot Recovery`
`Wipe Dalvik Cache`
`Wipe Battery Stats`
`Report Error`
`Key Test`
`Show log`
`Partition SD Card`
`Fix Permissions`

ce4

missing. hmm, should be started then

does show log say sth?

Pureferret

yes

two salient lines:

init.svc.adbd=running

and

ce4

8:11 PM

it should really work, very strange...

Pureferret

I:Skipping execution of extendedcommand, file not found...

ce4

thats ok

Pureferret

Hmmm

ce4

So: adbd is running, but the USB-enumeration fails with your PC

Pureferret

yes

ce4

8:13 PM

i.e. your kernel is maybe too fast to poll the S2 (hasn't settled just after plugging in)

Hence the "reboot phone while connected"

And the 'replug it slowly'

You can try another thing:

Pureferret

ok

ce4

mounts and storage => mount usb

Pureferret

sounds good

ce4

maybe this forces a re-enumeration

Pureferret

how do I get to that? Is that command or a menu in linux?

ce4

8:15 PM

in CWM again

It gives you access to your SDcard on your linux (totally forgot about that)

You can also use it to copy stuff

given it works

Pureferret

E:'Unable to open ums lunfile

ce4

lol

:-(

Pureferret

how about 'mount /data' etc?

lol?

ce4

that's just internally

lol because it's a hard nut to crack

Pureferret

@ce4 yeah

ce4

8:18 PM

Hmm, heimdall once again? Flash the new 6.0.2.7 CWM?

Pureferret

how do I do that?

is there a guide somewhere?

ce4

xxx

argh, it's for the sgh-t959

Pureferret

Ahhhh

ce4

clockworkmod.com/rommanager

This one has touch-enabled recoveries, and v.5.8.xx

I once used that

Pureferret

@ce4 which one?

ce4

8:28 PM

Samsung Galaxy S2 Download ROMs 4.0.1.5 5.8.1.5

The 4.0 is an old regular version, the 5.8.x is a newer touch-enabled one

Pureferret

@ce4 ok

ce4

Oh, and you have the i9100 (and not the i9100G)?

Pureferret

@ce4 I think I have the former

ce4

then 'heimdall flash --recovery image.img' again

Pureferret

ok hang on, I'm trying to find the img file in the zip, it's not like the last one I downloaded

I downloaded: recovery-clockwork-touch-5.8.1.5-galaxys2 but it doesn't have a .img

ce4

8:42 PM

argh

oldwiki.cyanogenmod.org/wiki/…

There's a link to a 5.5 version cmw.cmfs.me/c1/recovery/recovery-clockwork-5.5.0.4-galaxys2.tar

ce4

8:54 PM

@Pureferret: the difference is: the image is for flashing with heimdall, while the .zip (not containing an image) is for flashing via CWM itself

Pureferret

@ce4 Ahaha

looks like it's booting properly

you've flashed it?

Quplah

ah, fine

indeed

8:57 PM

hopefully adb comes up now

nope

same usb problems?

yeah

shh...

there's one more you can try

Liam W

Hi all.

ce4

8:59 PM

hey @LiamW
