Strange no one reply to you yet, the GSIII Sudden Death fix is in the XXELLA kernel (not bootloader) and if you're on custom kernel, Perseus is the first to have the new fix.

Yupe, I myself am not too sure about XXELLA kernel, still unclear from reading the various dev posts... so I flashed perseus kernel earlier today anyway instead while still on stock Msia JB

Very good analogy of the wear leveler problem described here

And very good explanation of why the workaround fix can work from the dev Entropy512

It is 100% confirmed that stock ICS 4.0.4 also had SDS and JB 4.1.1 of coz.
JB 4.1.2 is unfortunately not confirmed yet to have the fix as there as still some cases of SDS.

Like I mentioned before for me, just get Perseus 1st since nothing to lose while waiting

Yes, get it here
Perseus Kernel (XDA)

Just flash it, and use Triangle Away to reset the flash count. On stock Msia JB, you just have to reset the flash count once. In download mode, your binary will still be official. But to get back the stock kernel, you have to reflash the whole stock rom again (or restore from nandroid)

Seems that Entropy512 thinks 90% chance that Perseus fixed it and 75% chance for XXELLA/4 to fix it

A WTF update from the fella today, now claims a jig saved his phone
source: http://forum.xda-developers.com/showthread.php?t=2089302

1. Correct, just tick PDA.
2. Yes, the latest perseus can be used on any JB ROM. In future, if you flash any full JB ROM, this perseus kernel will be replaced...
3. If you have rooted before, flashing this new perseus kernel will not impact it, you will still be rooted.

Follow the steps here for ODIN (Yes, I know it is Note 2, but just showing you the steps which are the same)
http://www.androidauthority.com/galaxy-not...-kernel-143983/

After that, remember to reset flash counter using TriangleAway

You are using the XXELLA or later bootloader. The red dot (exclamation mark) indicates that your device is modified. 'Fixing' needs some skillz as unfortunately flashing older bootloader not possible due to blacklisting

I think most people here flash 4.1.2 via mobile ODIN so did not face this problem

Can also check by using terminal (you also need busybox)



Mine is (stock Msia JB 4.1.1); updated last year using Kies
android.bootloader=I9300XXALEF

Updated my post. Last update to 4.1.1 was via Kies.
No longer will do that though, as next update (4.1.2 Msia) I will flash using Mobile ODIN to not update the bootloader.

Actually XeactorZ is right (OTA is the one that probably updates the bootloader as well), my last 4.1.1 update using Kies did not seem to update the bootloader (his and my bootloader is still ICS Msia version). I am not very sure if Kies will be successful in updating my Msia 4.1.1 to Msia 4.1.2 as my device shows modified now (and also worried bout bootloader downgrade hassle; so to be safe I will update 4.1.2 using Mobile ODIN when Msia 4.1.2 is available from Sammobile)

The person who created that flashable zip has written comments (or rather print output) in the code in italian

That particular flashable zip is actually doing the operations described here

Using PerseusAlpha v31 I don't find much difference in charging (Using Battery Monitor Widget), it charges roughly the same time as the 4.1.1 Msia stock kernel. (Stock cable + stock 1A charger)
=> Reading the thread, Andrei is supposedly aware of slow charge issue but I am inclined to think it may be due to some app/stweak issues as well

On the stock kernel 4.1.1, the slow charge I sometimes get once in a while is because of the charging suddenly gets dropped to 499mA instead of the expected 999mA; if you notice it; plugging out and in again would solve the problem.
=> Have yet to experience it on perseus.

I will still stay on perseus anyway for the moment

Unlikely just clear Google Map cache can damage your phone...
What is the download mode status? If blank, and status modified, could be just bad luck and hit Sudden Death issue

If not that, possible just reflash stock ROM with PC ODIN will get your phone working again.

It seems ok, so should not be SDS issue, maybe other hardware issue; which you may have to bring to SC.
For now, just try reflash back stock ROM with PC ODIN.
Good Luck!

As far as I know, only if you can boot to recovery.
Once in recovery, you can use ADB shell to backup and copy the files to your PC/Notebook or if you have CWM, then can do backup with CWM to your sdcard.

If you reflash ROM, data is not affected, but normally recommended to wipe data.

Your question is not clear, you're in luck - just search for LTE in this thread and start reading from 1st page of the posts found.
Covers LTE flame war, coverage and models supported

Yes; but I prefer ODIN 3.07, go search Jayce Ooi blog for some vids if you need more help.

No same sudden death issue for 32GB as the eMMC firmware is different. FYI - it seems, the 16GB eMMC for Note2 is the same as SIII as well so that is why there are some cases of sudden death as well.

If worried about SIII sudden death, read this to mitigate your risks

Yes, mobile ODIN is unable to flash bootloader.
At this time, the new bootloader is not required. Not yet any good reason to flash it.
At the moment, what is known is that you do not need the new bootloader to be secure against SDS.
The stock 4.1.2 kernel is enough, so you're good.
