[Q] Galaxy s2 data recovery when panic upload screen

[timmib]

Greetings,

My son has a Galaxy s2 running stock 2.3 which he bought in Singapore over a year ago, I think. He states that it has not been rooted. Over the last several weeks he has been getting the 'kernal panic upload mode' screen when the battery was getting low. Last week it became permenant regardless of the battery level. Yesterday I was able to talk him through entering recovery mode. He wiped the partition cache and rebooted with no apparent effect. A picture of the recovery mode screen idicates that the system was unable to mount /data (unknown error: 0). But it did show media files were copied succesfully. ... I've attached a picture of the screen. The phone is no longer recognized in Win7.

My basic question. How might we rescue the pictures and some text from the phone before redoing the os?

TIA,

Kim

Kim, flash siyah v5 and try cwm.
Also drill your son on what is that he did exactly, cause he must have done something.

I had thought that if all else failed I would have him use Odin to re-apply his existing os. My thinking was that the file and partition structure would be close enough to what's there to allow normal usb connection and to d/l his pics and what not. Then I'd get him to install something with a little more support for recovery and snooping about. Decent enhancements!!

I don't know what he did other than I think he might have overloaded the little beast with too many apps constantly calling home on an older os. But, that's just a guess. Thanks for the upgrade suggestions. I'm only starting to research that aspect. I suspect that going direct to the better burns will be the way we'll end up going.

Be well,

Kim

Siyah is a custom kernel, no danger regarding existing data.
By flashing it you'll be able to access a temp recovery called clockwork mode.

Greetings gastonw,

My son's getting the usb drivers from the Samsung site for the i9100. I found the tar Siyah-s2-v5.0.1.tar for Odin.
Odin3 version is 3.04. Don't know what else I need.

I'm going to be doing this long distance and I've not handled a smart phone personally so ...

1. Start the phone in download mode.

2. Connect phone to computer

3. Start Odin (making sure that Kies is not running), Odin should recognize the phone.

4. Load the tar in the pda section

5. check automatic reboot, and start.

6. I presume that I will know when it's done because odin will report success or finished, and the phone will boot.

To grab the data off this phone do we use the recovery mode or will it now be called clockwork mode?

At which point I presume we shut the phone down and do a normal start/boot.

Any thoughts would be appreciated. Thanks for your help. Reading the specs on the Siya work I'm almost tempted
to go get a phone for myself.

Be well,

Kim

Lol, that's awesome, your playing by the book
Custom recovery will become CWM instead of stock recovery.
And go ahead and get yourself a new phone, you're in for a hell of a ride.

Thank!! My son called and said the usb still doesn't work. Hum .... I hope not, but I may be back to see if there's a way to transfer something from an sd card in order to save the data. On the flip side ...

Odin doesn't see his device or the pc calls it "unknown device"?

Can he get it to boot, he can use airdroid app or dropbox to transfer over wifi.

The custom kernel is just to get rid of that pabic message.

Mornin' gastonw,

Well, as of a couple of minutes ago, win7 did not recognize the phone. Hopefully with a reinstallation of the Samsung specific usb drivers win7 and/or Odin will recognize the phone.

Interesting. When he booted into download mode the top of the screen said something like, 'Odin download mode'. Does this indicate that it might be rooted? To the best of my knowledge he was unaware of the three button boot loader mode and hence would not have changed the phone from the basic generic non-branded phone that he bought. Just wondering. If it is rooted is there a way to manually do, via the recovery mode, what Odin will be doing? It seems to me that if recovery allows to d/l from the sd card there must be a destination to be designated. I have no idea what the drive and directory layout is, and I'm a tad rusty on linix shell commands, don't even know what shell android uses. But, if I knew where the package had to go ... .

I'll write again when I know more.

Thanks again,

Kim

Well the last I heard is that no USB *and* it's probably a win7 problem!!!! Good golly miss molly!

Anyway, snooping about I found a thread [howto] which indicated that putting a clock work mod zip on an sd and d/ling it thru the recovery mode would install the clock work mod recovery boot.

Now I can not find a further reference to a zip with the name format used in this post. However at the modclockwork site I do find two
http://clockworkmod.com/rommanager. One is for 'touch'. I don't know the difference between the two. But, am I understanding correctly that I can put the appropriate zip on an sd from which I can d/l thru the standard recovery mode which on restart I presume will give me access to cmw recovery mode? Seems to easy. LOL!!!

Any help would be appreciated.

Kim

This is how you root & flash cwm via recovery: http://m.youtube.com/#/watch?v=7psIQU69h3M&desktop_uri=/watch?v=7psIQU69h3M&gl=MX

Tell him to try another PC to see if it sees the device.

Genuine s2 usb I assume?
