From MDL 4.2.2 to CM11 (M3) and back - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi. I'm not sure how to even ask this question. I've heard that the OTA 4.3 version of Android does something to the bootloader and disables loki patches or something like that. My question is... If I'm on MDL 4.2.2 now with Loki patch and TWRP recovery... if I use the CM11 web installer from CM and upgrade my custom rom to CM11 4.4.2... will CM11 mess with my bootloader to where I have to revert to SafeStrapper? or does CM11 not mess with the bootloader to which I can continue to install any rom I want? thanks

No, it won't mess with your bootloader. If you update your firmware then your on trouble. But you're just flashing a custom rom so you're ok.

Flashing ROMs is fine, but just so you know the CM Installer does not work on our device. You have to flash it in recovery.

The latest SuperSU that you flash in recovery is the only thing that works on AOSP/AOSP based roms (Anything that isn't Cyanogenmod, AOKP, ParanoidAndroid, PAC, etc)
You have to flash this unless you want broken sensors: http://forum.xda-developers.com/showthread.php?t=2147194
Select the first zip and flash it before that rom of your choice or you will have problems.

Android 4.4.2 and MDL bootloader on I337

I have I337 with MDL bootloader. Omega 19 (4.3), MK2 GSM modem and MDL LTE modem.
New Omega 20 based on leaked 4.4.2 come.
I read Omega 20 installation notes than it works only with new 4.4.2 bootloder.
Does this means that the only way to install 4.4.2 is wait i337 4.4.2 stock, flash it and use safe strap.
PS
Is LOKI kernel for 4.4.2 TW available?
Was kinda wondering this myself.
I'm on 4.4.2 GE ROM, I assume just flashing a 4.4 ROM updates your bootloader but strangely I don't see any 4.4 TW ROMs in our Dev section yet?
Was hoping somebody has flashed an Intl 4.4 ROM with loki-doki and all was good.

Flashing a rom only updates the system and kernel. The modem, bootloader, and recovery stay intact. Odin packages contain the bootloader and modem. These are all on separate partitions.
The 4.4.2 released was a i9505 rom and only for them. You can be on an older bootloader and flash newer android version roms but you can't do the opposite and say flash a 2.3 rom while you on a 4.0 rom.
Also most people don't want the permanence of being stuck on a leak release and not being able to go back.

Ahh ok, so I really do still have an MDL bootloader huh (even though I've flashed different modems).
But I can switch from a 4.4 GE/CM ROM to any 4.3 or 4.2.2 if I choose, so what do you mean not being able to go back?

MDL was the second update I believe (right after release) for 4.2.2 before the the lock. Once you update the bootloader on these lock bootloaders (even MDL is locked, just has a loki work around) you can't go back. The bootloaders are going to be locked and you wont be able to flash a Odin .tar and go back. You are on there. YOu can flash 4.4 roms on a 4.2.2 bootloader but not a 4.2 rom on a 4.4 bootloader.
Alrighty, so to answer OP's question.
You should be fine to flash new Omega with a wipe of Cache/Davlik/System/Data followed by loki-doki.

not unless he is okay being stuck with a he new bootloader knowing he cant go to another rom unless its a 4.4
Omega (and all custom ROMs) wouldn't include the bootloader as you mentioned in your first reply...

It's true.
I am confused by what I read in the installation Instructions for Omega v20:
Installation:
1. Backup your device (nadroid backup, titanium backup, efs backup ... etc) and save the backup to a safe place.
2. Flash the new bootloder and modems with odin -> I9505XXUFNA1_Bootloader_Modems.tar

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.

[Q] AT&T I337 MDL - Newest Firmware

Been trying to read and figure out as much as I can, but I'm lost. I rooted my phone right when I got it a few months after release. I have the MDL firmware and I'm running stock that I've modified to my liking. I rooted using motochopper, I have TB and SU and I have TWRP installed. I'm ready to take the jump and try to get an updated firmware, but don't know where to look. It seems a lot of the info in now for the newer firmwares.
I would like to run either Google edition or a modified TouchWiz I think. I like keeping things pretty clean and fast. I am currently running Aviate on top of TouchWiz and I like the clean organized feel of it, although a bit laggy.
Please help me XDA, sorry I know this is a newb post. I've been blocking the OTAs for over a year and I'm ready to move on.
First I would suggest NOT to use any STOCK firmware to update to 4.4.2
There are some newer Google Edition Roms I believe in the ATT original ANDROID SECTION. You can use them since you have twrp recovery. Those with newer firmware cannot use the latest google edition Roms unless they are made for safestrap.
Or if you want a modified stock Touchwiz with all the extra benefits you can flash directly to ShoStock-i 8.1 which is 4.4.2 based.
Keeping you MDL bootloader and the Loki bootloader bypass you have now let's you flash ANYTHING you want, including kernels.
If you update firmwares the bootloader becomes MORE LOCKED DOWN and you cannot flash any Roms that need a modified kernel like aosp based Roms, or any kernel other than stock.
Thank you ill check those roms out. I am aware that I DO NOT want to update my firmware, that's part of the reason I asked for advice, to see which roms work well with MDL. Most of what I found was all for newer FW versions.

Would I be better off upgrading to OUDHS Touch CWM-based Recovery 1.0.3.5 instead of TWRP so everything is auto Loki'd?

Sorry I haven't tried OUDHS so I cannot comment. But TWRP still works perfectly. For ShoStock you would NOT need to flash Loki-Doki patch or anything. The kernel in ShoStock-i is already Loki patched. If you plan on trying other Roms it is always best to keep the Loki-Doki flashable zip on your sdcard and flash it after flashing a ROM. Just extra insurance that won't hurt anything if the ROM is already lokified.
Ok going to try flashing this

Recoveries? Android 5.0.1 SGH-I337

How exactly do I go at getting a recovery now? I've tried installing twrp ,cwm, philz, and safestrap. The I337 I've heard has a locked bootloader though I find this hard to believe for all the custom ROMs. I heard others often experience "System software not authorized by ATT has been found on your phone". Help would not be taken for granted.
If the phone is running a 4.3 or newer bootloader, the bootloader is locked and can only use safestrap to flash custom ROMs.
There are many custom ROMs (there are different versions of the s4 and some of these custom ROMs may be unified builds for the 9505, 9515, i337m, etc.) but only those custom ROMs that can be flashed with safestrap can be flashed to an AT&T s4 with a locked bootloader.

If you're on Android 4.3 or higher then you can only use safe strap and boot touch wiz roms as your bootloader is locked and patched. If you're on Android 4.2.2 or below, you can install TWRP and boot other custom roms like AOSP and Cyanogen mod as the bootloader is locked, but not patched and can take advantage of the loki doki exploit to bypass the lock.

I have 2 phones. One 4.2.2 another 5.0.1. Is there a way I can update with twrp or another custom bootloader and then update to 5.0.1 (not through OTA). Which one should I use? Thank you.
There is no such thing as a custom bootloader for the att s4.

I'm still somewhat interested, even with safestrap. The bootloader cannot be unlocked. OTA update wouldn't be possible as it checks the recovery. I'm interested in ROMs and nandroids.

Is your 5.0.1 one on the OC2 bootloader? It then can only boot touch wiz roms. Golden eye rom and thor rom are good and both can be booted in safe strap which is the only recovery it can use. Your 4.2.2 phone is on the MDL bootloader right? If so use towel root to root it if not already root then install loki doki then install TWRP. After that pick a kernel and boot whatever rom you want...touch wiz, CM, AOSP, etc.

The bootloader lock can only be bypassed with the loki doki tool on the MDL and MDB firmwares. If you're on any other firmware then you're stuck with using safe srap as the bypass exploit was patched in the MK3 bootloader OTA update I believe.
