[Q] gt-i9505 rom on gt-i9505g?

I'm pondering getting a GT-i9505G (Google Play Edition), and was wondering - since the bootloader is unlocked, could I flash a Touchwiz based i9505 rom to this device with something like Mobile ODIN to skip the modem (since I presume it wouldn't be compatible?).
Anyone heard anything about this?

If it does have Download mode you will be able to flash the system etc. And otherwise you will be able to flash a flashable zip in CWM

I was thinking about the same concept, but only a little bit more radical.. Let me explain: I recently flashed my Galaxy S 4 GT-I9505 to a GT-I9505G (I rooted my phone and put android 4.3 on it). The only problem is that it was a test version of android, so it has a few, but very annoying bugs, like a huge battery drain from time to time and some very specific app crashing.
I was wondering if I can flash my phone back to stock, the way I bought it (with android 4.2.2 and TouchWiz skin). Is this possible by flashing the stock GT-I9505 firmware on my device (hence the GT-I9505 and GT-I9505G are almost the same devices), or is there another way? And do I have to root it again?
FYI: I have also made a TWRP backup of the situation right before the flashing of android 4.3, but if I want to do it that way I have to root it and flash TWRP right?

Yes, you can ODIN back to complete stock I9505, and yes, you'll have to re-root, unless you flash a pre-rooted ODIN file.

So if I understand correctly I have to root and flash TWRP, and should be just fine if I restore from that backup?

You should just be able to flash TWRP from ODIN, then restore from your backup. Seems easier.

[HELP] Downgraded S4 from stock 4.3 to 4.22 Failed. Stuck with Samsung Logo

Hi all,
I tried to downgrade my S4 from the stock 4.3 to the 4.2.2 using odin. Odin success without any error.
Phone rebooted, but stuck with the Samsung logo.
Did I just brick my phone?
Any help? Thanks.

Did you do a factory reset BEFORE doing the ODIN flash downgrade to 4.2.2 ?
If not you need to do that and reflash using ODIN.
Also be 100% sure that you are flashing the correct and specific model/baseband
version of the 4.2.2 stock firmware for your phone.
Only use/download ODIN flash stock official firmware from: http://sammobile.com
for best results.
Good luck!

I would factory reset my phone but I would still get a error, does the process only work with the international version of the S4? because as far as t-mobile, I don't think we have any luck in downgrading to 4.2.2

all you need is reflash official 4.3 firmware using odin. once updated to 4.3 it is impossible to downgrade to official 4.2.2.
so just reflash 4.3 official again and your device will boot up. i myself faced this problem .

so it's impossible to downgrade to official 4.2.2, but is it possible to flash a custom stock rom on 4.3 or 4.2.2 (like a modified stock rom)?

You've most likely got the KNOX bootloader due to this you can not downgrade to an earlier version of an official rom. Custom rom's should work fine not sure about 4.2.2 roms.

Would a equalivalent version of a custom rom work? because I plan to install jovy23's stock SGH-M919 4.3 modified rom, but I am not able to install it due to the errors given by CWM and TWRP

[Q] ODIN flashing older rom.

Hey guys so i have heard that if i install the old firmware for my s4 from sammobile using Odin one from early 2013 that it will give me access to service menu so that i can unlock my phone. So my question is that is it 100% safe to Odin flash the older 4.2.2 rom when i am on 4.3? Can i flash it unlock my phone then upgrade my phone to a custom rom again? Thank you

Do not do this. This will brick your phone. If I am not mistaken, there is a method to unlock mk2 in the general section.

You should ask this in the t mobile s4 forum. I believe your bootloader is unlocked and you can flash an older firmware version. But check there first. This is the att s4 forum. It can't be done on the at&t s4.

Is the service menu missing on the stock T-mo 4.3 ?

Nooo guys i have an unlocked bootloader i have the s4 that is very similar to the tmobile and it's the same as the Canadian versions. And yes the Canadian version which is 1337m and mine which is m919v don't have access to service menus but i have flashed a lot of custom roms simply by philz recovery so doesn't that mean i have an unlocked bootloader?

If you're on 4.3 I believe you also have Knox, in which case I don't think you'll be able to go back to 4.2.2. Read through this http://forum.xda-developers.com/showthread.php?p=40903040

Did you ever take the ota to 4.3? Do you know what firmware your device is on? A 4.3 custom Rom wouldn't have knox but if you took the official update to 4.3 you would have Knox.

Hmm i think then yes i might have knox. I think at one point i might have been on stock 4.3 is there any way that i can check to see if i have knox? And if i have knox i cant flash an older stock firmware for my s4?

Idk, I'm not that familiar with your device. From the little bit of reading I've done I would say no, you can't flash an older firmware. But again, I'd post this question in the t mobile forum. They'd be more familiar with your device.

Did you ever update you device with kies or ever take an over the air update ? It's fine if you were on a stock based 4.3 rom as long as you never took an official update. If so then you can't go back. Just flashing a stock 4.3 rom won't change that status but the 4.3 bootloader would.
You would have know by checking in settings under SE

Returning to stock australian 9505

Hey guys was hoping to get a little help. I am currently running foxhound 4.1 on my S4. The baseband version is I9505XXUFNA5. Its OS 4.4.2. In the process of flashing this rom according to the instructions on the dev thread said i had to flash a different bootloader and modem before flashing the rom. This process worked fine and i have been running without issue. Work has now decided that they want everyone on Android 4.3 so we can use apps they made to make our job easier so i need to go back to 4.3. I attempted this last night and when i try to flash a 4.3 rom via cwm it returns an error saying that the bootloader is the incorrect one and fails and i have to reinstall foxhound again to make the phone usable. Any one know how i go about getting back to 4.3 or where to get the correct bootloader and modem so i can flash them via odin and then install Androind 4.3? Any help would be very much appreciated.
Cheers Jeff

Nobody can downgrade from 4.4.2

WTF really?? Cant i flash 4.3 bootloader and modem and then go back to 4.3?

Nope not at this stage cannot downgrade to older bootloader, sorry.
The best you can do is install a 4.3 custom rom. Try an echoe rom, version 12.1 the final bean I think should do.

You cannot downgrade from 4.4.2 to 4.3 and if you have a 4.3
nandroid backup you cannot restore it either.
You will only be able to upgrade or flash 4.4.2 roms and newer
versions of android roms/firmwares.
Oh, one more thing there is no such thing as "denox" LOL
Good luck!

Yeah you can flash Stock via ODIN or you can install CWM/TWRP and use a custom recovery. -- Make sure REACTIVATION LOCK is OFF before you do anything or it won't work.
