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/showthread.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/details?id=net.hellcat.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:good::good::good:

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?
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

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..
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

Sorry that's hated to read.. the tar.gz is only 29.00B
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

And also I'm rooted but no cwm or roms yet. Just info in case it helps.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

Oooooh, I already spotted a few things!
OK, that helps a lot already, thanks!
I'll prep a testbuild and if you don't mind you can test it?
Did it fail the check for the .TAR as well, because as far as I can see, the .TAR backup schould have worked.
// EDIT
Hmm, the next big question is, is this for all US variants or only the AT&T one.... guess I'll need to wait till someone with one of the other variants shows up and will take them out again for now....
// EDIT 2
Ouch, and what about kernel, recovery, modem and all the other partitions.... gotta find a way to figure out those too....
// EDIT 3
And me again....
Could you please try the following command in the terminal as well:
Code:
su
ls -al /dev/block/platform/dw_mmc/by-name
If it gives a list of entries, please paste it to me Thanks!
// EDIT 4
OK, finding clues for more and more differences.... why Samsung, oh why do you do this....?
I could also use the output of
Code:
su
ls -al /efs
*sigh*

Those sizes are OK.

When I flash back stock backed up zImage kernel, on any custom kernel, the recovery flashed along with that custom kernel will be retained? can I use that recovey with stock kernel?

Yeah.
The S3 uses a seperate recovery this time (unlike the S2, where the recvoery was part of the main kernel).
So if you flash a kernel, the recovery will remain unchanged.

OK, I think I found a partition layout for the i747 - maybe someone can confirm this being correct?

it is a 'stock recovery' flashable zip. and with all zip files, yes it is viewable on the phone.
its mostly full of patch files. and patches around 200 files. 178 of those are system apks getting patched... largest patches going to samsungservice, flipboard, polaris , clock package, browser, and datataduh!!! googlequicksearchbar.apk ***removing universal search i would be guessing... for anyone that keeps up on the apple/nexus debacle..

I put this on the SD card (btw i was stock non rooted) went into recovery and ran it.. i lost all my files smh! it was a ten mb file .. wth?

it wiped the system. only takes a line of code. dont matter how big the file is..

Nice to see you here TRusselo. I take that you own a SGS3 now (with Rogers?). When can we see you amazing ROMs for SGS3? Much appreciated your work you did on Captivate.

After installing CWM my ota updates fail do I need stock recovery to ota through normal phone process?? I have been able to retain root by using OTA Rootkeeper but I had not yet installed CWM and am concerned about the next update. Thanks for any advice.

I haven't, but I work from home and am on wifi most of the time. One person reported that calls were being dropped when switching between two calls (call waiting) using the LEM modem but that was fixed with the LG1 modem. Another person reported in the OTA thread better performance with the new modem.
Give it a shot. You can always go back to the LEM modem if you want.

Does anyone have a CWM Flashable version of the T999VVLDLL1 Jelly Bean Modem?

As you all know, the T999V variants and T999 can not flash the radio/modem files interchangeably between the two.
As such, does anyone have a copy of the Modem? I'm currently running an JB Rom with an ICS Modem and getting some really sad speeds. I checked the Sticky here:
http://forum.xda-developers.com/showthread.php?t=1880987
and it is currently not posted.
If anyone is using this Modem, I believe you could follow the steps in this guide to a certain extent:
http://forum.xda-developers.com/showthread.php?p=27584839#post27584839
Thanks in advance to all that reply!

after further googling, I think all I need is some kind soul to extract the modem.bin from their phones. Afterwards, I think I have enough tech savvy to repackage the Modem.bin into a CWM ZIP file for public consumption.
Please follow the steps using either ADB or Terminal on your phone to extract the modem and then post it here. Thank you!
Requirements:
1. CWM Recovery & root (Thanks Chainfire!)
2. ADB setup and know how to use it! or Terminal Emulator app
3. Samsung KIES drivers installed
4. Power on device, Enable USB debugging
**If you don’t how to do above, then XDA forum search and Google is your friend**
Steps:
1. Dump your current modem onto your internal sdcard

Just wanted to say thanks for doing this. I offered a month ago to do this for the thread if someone could help me figure out how to export the modem and I see you just sat down and figured it out. Thanks for the taking the time to do this, Support Canada! T999V forever!

How does this compare to VLLH2 in terms of battery life and performance?

For me it's the same as the previous version. Maybe better signal if you are far from the tower.

Anyone know why does the updater script and radio file still say VLLH2 for the baseband file name? I'm assuming that it is just a left-over from reusing the packaging from the previous baseband zip.
Has anyone tried this and confirmed that it is truly VLDLL1 via the About/Phone menu?
File sizes are different -- new version is quite a bit smaller...so they are not identical...

I'm getting mixed inputs here. I have a t999 T-Mobile Galaxy S III and every time I update my Cyanogenmod ROM (which I've been doing for years) everything goes smooth but when the device boots up, it says "unknown" for the baseband version. If I flash the UVDMD5 radio it goes back to normal. But every single time I flash a new nightly this happens. Just wondering if this is a fix for that or if there I no fix. I rooted with the stock root injected .tar file just like I've done 3 separate times. This is the only one of my 3 S3's that has done this. I confirmed that it was NOT a t999L model before anything. Is there a possibility that this device could be a non t999 without saying it is? Or is it possible that this is a t999L model without showing that it is? I'm very lost here. Nobody seems to have the same issue as me. I've searched through hundreds of thread pages to no avail. Help please somebody?

I've no idea why it would do that. Sounds like some sort of Rom issue maybe? If it was anything but a T999, the md5 modem would not work btw. But I've never heard of thus before, so it could be some sort of unknown corruption somewhere in another partition. Purely a guess on that though.
If you Odin back to the LJA, or any other build does it still do this? Does it happen when you flash any Rom? Or just cm? If it's only cm, then I'd ask in the Rom thread. What about other kinds of flashes, such as kernels, recoveries and mods?

Please make sure you have a recent back up of your phone. Also doubly make sure to backup your /efs folder and your /dev/block/platform/15570000.ufs/by-name/RADIO device. There is a risk of permanently bricking your device if the radio upgrade fails. Remember this is all at your own risk. I promise no function or fitness of use. This will probably cause your phone to blow up and start a thermonuclear war and trip your Knox counter

then adb pull those files to your computer and put them in a safe place

Looking at the package, it only replaces your System partition, your Kernel, and your Radio.
An Odin-to-Stock would theoretically revert any damage this could do.

Are you using the twrp posted in the op? Are you doing sideload or straight from the device (fwiw I only tested sideload) gimme a second and I'll add a md5sum
EDIT: MD5 (blck_tw_511_samsung_oe6.zip) = 6a96ab53a25ff76fb263a06a7efa256f
EDIT2: Just downloaded from mega and the file matches the original's md5

I say the first bricked phone will happen within 2 hours..
Folks, if you dont REALLY know what you are doing, please reconsider flashing this. And, if you dont know what ADB is, or what sideloading means, do NOT flash this...
And, mega thanks to the OP for putting this out there for the early adopters! :good::good:

Can you expand a bit on what this exactly means- the two lines of script you posted here- are those the ADB pull lines we would use?
Just want to be completely clear on what we have to do to backup before we flash this ROM. Step by Step would be great.
Thanks again for all your work on this!

Working so far...

Very nice bro I'm so happy for the H815 community. I also will release today the actual H811 Full Nougat version based on the Korean system dump and modified modem. A great day for LG G4

A big thanks and respect to you mate.

Dude, that's awesome! The community will never forget that :highfive:

So how does one unrooted person use this? Is it possible for someone without root to modify the Korean version and use this modem?

@keriox Thank you so much!
As @Velkyrix said, will we be able to get this working on devices that don't have root or custom recovery?

I honestly didnt think you would, thanks a lot, currently downloading it I will update when I flash it.

Any tips on how to run it on the h815p with no root or bootloader thats unlocked

I think it's better to wait for someone to create a flashable zip.

I think this is the code to flash modem.img. Got it from updater script.

I have not tried it (I can't unlock the bootloader), so you tell me if it works for you.
good luck!

From the way it looks like, non bootloader unlocked phones can't use this...
Well that sucks
(There is the possibility of actually modifying a kdz to make it work with that modem, but idk if that's possible)
