so, i just got this phone: i337 on 5.0.1 with baseband i337UCUGOK3.
I have read a bit on xda.
Is it true that i will not be able to in any of the custom 7.1.1 rom on this phone?
Nougat can't be installed on a phone with a locked bootloader.

I upgraded to S6 so i want to hand down my S4 and want to make sure i don't brick the phone.
i want to restore back to 4.2.2 MF9 unrooted and stock recovery and let the phone OTA to current version.
iirc phone is running unlocked bootloader version (MF9?) phone info:
SuperS4 ROM (L720VPUFNAE) Android 4.4.2 running TWRP recovery
Bootloader Version: L720VPUMF9
Baseband Version: L720VPUAMF9
PDA Version: L720VPUNAE
would be helpful if someone can post a link to the correct file i need with unlocked bootloader that will restore my phone to factory. tried one from the sammobile website but it's painfully slow.
TIA.
I have the AT&T Samsung Galaxy S4
Android Version 5.0.1
Build I337UCUGOK2
I've already unrooted it.
My question is, can I install custom roms to it?
I read somewhere on xda that I can only install roms based on the base one using Safestrap.
I really wanted to install cyanogenmod, but on the page there's the warning ''you must be on build I337UCUAMDB or I337UCUAMDL or this will not work''
Any help would be appreciated.
Not possible without unlocking bootloader
I am in the same boat. Unfortunately at the moment there is no way to get CyanogenMod from OK2. I have spend so many hours trying for the same. The conclusion is that the bootloader is locked and there is no known method to unlock the bootloader on I337 yet.
hi
i purchased a unlocked at&t phone off ebay and it works fine but its on 4.4.2. i want to root and install new custom firmware based on the S6/7 rom - newest android basically that'll work.
What rooting guide should i use and whats the best rom to get it flashed to a UK based rom?
If you are on 4.4.2, do NOT take the OTA update. updating to the official AT&T Lollipop gets you an encrypted bootloader that is unlockable.
look for guides based on 4.4.2. you'll want to install a recovery, then you can flash custom roms.
I have a question since I watched the youtube video on how to upgrade my phone samsung s4 at&t to Oreo, but I read that I need a bootloader. Then when I read articles here in xda, mostly says that this phone can't be unlock? so How do I deal with this? Please explain simply because I am new in this.
If the phone is running an MDL bootloader, it may be possible to flash Oreo. If the phone is running a newer bootloader, the phone can only run TWRP and will not run Nougat or Oreo.

You cannot unlock the bootloader. However, if you're on the MDL bootloader then you can use an exploit called loki doki to install a custom recovery and a custom ROM. If you're on a newer bootloader other than MDL, then you are stuck with only booting custom touch wiz based ROMs and must use safe strap if on kit kat or flash fire if on lollipop.
Can you oden back to mdl if you are running NJ4.
does it matter id i upgraded to Kittkatt with a custon rom vs ota update on if the bootloader got locked? does goldeneye kittkatt 4.4.4 lock the bootloader?

No you cannot odin back to MDL, if you try you will brick your phone. It doesn't really matter how you update given your bootloader is locked (unless you're on the MDL firmware). Golden eye ROM does not lock the bootloader, no custom ROMS lock the bootloader.
I have a G920T (T-Mobile ) running Android 5.1.1. It's unlocked ,rooted & has custom rom TWPR. I would like to know if flashing T-Mobile stock (Android 7) rom will re-lock my phone. I don't know which method was used to unlock. Currently I can flash any 5.1.1 custom rom & it's still unlocked but I need to update to 7.0 which requires updated boot loader. I'm afraid it will lock the phone.

IK that you will lose root and TWRP by flashing stock firmware.
But IDK if the bootloader will be locked again ... probably yes.
Then you may have to unlock the bootloader afterwards. Best to check for unlock methods available for your device running stock Android 7.
