Use this to downgrade 4.3 to 4.1.1 - flash using custom recovery

http://mediafire.com/download/9y2xo8..._for_fzeta.zip

Then use these instruction to unlock your phone.

Put a different SIM to your own into the handset and then turn off the handset and switch it back on with that SIM inside.
Go to the dial pad on your phone and then type in *#197328640#.
Head over to the Main Menu of the device > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > and wait for around 30 seconds.
You should then head to Menu and choose Back, where you will come across the Network Lock. Choose [4] NW Lock NV Data INITIALLIZ.
Enter *#197328640#.

That's it your phone is now unlocked. You can now use any sim card.
You can update, Root, flash custom rom and everything you want. It will stay unlocked

Unhappy
I got really excited when I saw this, coming from a new thread I made after discovering the inability to downgrade to 4.1.1 after Knox is installed.

However, I ran into a snag (I'm trying to downgrade from 4.4.4, i9305 with CWM 6.0.4.7):

format() expects 5 args, got 4
E:Error in /data/media/0/stock411.zip
(I renamed it and copied it again to internal phone storage in case it was a bad transfer to ext SD card previously)
(Status 7)
Installation aborted.


Any ideas?

Did your 4.3 phone definitely have Knox installed before?

Is this issue occurring because I'm coming from 4.4.4?

Thanks for your input.

Have you tried using TWRP recovery instead?

No, that may well have been my next move, but oddly enough I managed to seemingly very flukely flash a stock 4.1.1 ROM with Odin just now, download link here:

TBA (can't post links yet)

Wasn't expecting it to work at all and almost didn't try, given the previous 'Unsupported Version' messages when trying to downgrade to other stock ROMs with Odin, but there you are, this time it worked, somehow...

The rest of the trick with the dialler menu worked a treat and I now have a SIM unlocked (though faulty, GPS doesn't work) SGS3

Hi,
I have a Samsung I9305 LTE, with official 4.3 rom. I don't care about warranty (as it's expired anyway), and the unlocking stuff (I can use whatever SIM card, so I guess it is an unlocked version?), all I want is to flash a custom rom. What do I need to do?

Hi,
I have some questions too. I am a new I9305 owner.

I have the 4.3 bootloader, I don't care about Knox as I have no warranty (phone was 2nd hand). I've already tripped Knox anyway after flashing Philz recovery and rooting with it.

I have two requirements really, which I think are more kernel-dependent than ROM-dependent.

1) White balance/colour calibration. I hate the blue-green tint to the whites.
2) Wolfson/Boeffla sound controls for the Wolfson DAC.

I don't really care if it's Android 4.1/4.2/4.3/4.4, AOSP, CM or stock.

So far I still have the Samsung stock 4.3 ROM but I've flashed the AGNI v3.8.5 kernel which has given me some sound controls, but nothing useful regarding the display. Ideally, colour multipliers, black level, gamma etc.

The Perseus kernel+Stweaks looks like it might fit the bill, but I think it's 4.1.2 only and I'm not sure if it works with the 4.3 Knox bootloader? I'm happy to switch to a 4.1.2 ROM if I can, I just REALLY want to be able to fine-tune the screen!

Maybe there are other kernels that support this for 4.3 or 4.4? Or do any CM builds have the screen controls in the ROM itself?

Thanks!
Glenn
