[APP] kTool for the SGS3 - easiely backup/restore kernel, recovery, EFS

---

Hey ho

kTool - a little helper app some might know from the S2 - is now fully compatible with the Galaxy S3



For those who don't know about it, here's a quick rundown of the features:

• Dump current kernel and recovery
• Flash kernel from /sdcard/zImage
• Flash recovery from /sdcard/recovery.bin
• Backup EFS
  (as raw .IMG dump and as .TAR archive)
• Check/Verify EFS backup (i.e. compare to "live" EFS)
• Restore EFS from either .IMG or .TAR
• Open stock update .TARs and flash from from it:
  - Modem Firmware
  - PARAM.LFS
  - Kernel
  - (Recovery to be added in a later update)
• Reboot device
  - normally
  - to recovery
  - to download mode

And here's the original release thread in the S2 section:
http://forum.xda-developers.com/show...php?p=18652863

Find more details (and screenshots) and answers in that thread, however if you got more questions or suggestions you can post them in this thread as well


You can grab the app from Google Play (free):
https://play.google.com/store/apps/d...droiddev.ktool


Also, as there will be as many different variants of the S3 as there are for the S2, it might happen that you got an S3 but the app refuses to run.

In that case, please send me (via PM, email or posted in this thread) a screenshot of the "Incompatible Device" dialog and I'll update the app


Hope you like it.

Thanx M8.
How 'bout a new kernel. In Dev. Maybe.. lol
Seriously great work used it on my gs2.

Wow,

Great Job, thank you very much.

Now everything on air for SGS3,

Now I can test any Kernel, since I have backup of the stock kernel to go back

Perfect

This doesn't work for the ATT Galaxy SIII. It goes through successfully but says the nv_data.bin is Not found in backup.

Hm.... that's weird....
Could you do me a favour and open a shell/terminal on the phone and paste me the output of the "mount" command?

Also what are the sizes of the created "efs.img" and "efs.tar.gz" files?

It's the i747, isn't it?

Yes the 747 will terminal emulator work?

Yes, will work perfectly

Just run "mount" and make a screenshot, that's the most easiest way, I think.

The file sizes are both real small..

Sorry that's hated to read.. the tar.gz is only 29.00B
