Hi need some advice, I’ve got a J5 pro, but it’s locked to Voda! Also has enterprise firmware on it as it’s a old work phone, would like to remove this and unlock it to all networks. Can anyone recommend any good rom (close to stock) and best way to remove operator lock?
Can you access developer's settings?
If so, you could unlock bootloader and then trying to install another official ROM by Odin.
Don't use Pie ROMS, you cannot then downgrade, and modding becomes harder.
From Oreo,with some add from Pie ROM (BL, CP images) you can then install Treble ROMS until Android 10.1
Please look at Corsicanu, Andy_Yan, ananjiaser, Hacker Treble & Spaget threads.

Hi all, I'm relatively new to the Android world and seeking help from experts here.
I recently bought a used S7 (SM-G930K), it came with Android 8.0 and I want to downgrade to 7.0.
I tried downgrading using its stock firmware with Odin. Attempted many times but only realized that it can only be downgraded as far as the bootloader version goes.
Think my S7 was on bootloader version 2. So as checked for the available stock firmwares, the "earliest" version 2 was still on Android 8.0 (PDA G930KKKU2ERJ1 and CSC G930KKTC2ERJ1).
Anyone can advise me how to go about downgrading to Android 7.0? Though this S7 may not be my primary phone and there's obviously no warranty, I won't want to brick anything.
Do I have to downgrade the bootloader version to 1.0 first? And how do I do that?
Apologies, do excuse these noob questions, I'm not familiar with many Android terms. Cheers!
Model: S7 SM-G930K (KT Telco)
Android version: 8.0
Baseband version: G930KKKU2ERJ1

Basically, on Samsung phones, once you upgrade your bootloader, they put a lock on it, so you can never downgrade it, for security reasons, of course.
The only thing you can do is flashing custom rom, or stock rom with custom recovery & kernel.

I see, now i understand why..
"Custom roms" - does this mean it's made by users like us? And what does "stock rom with custom recovery & kernel" mean?
Can you point me where can i find these roms for my S7? Is it the same as flashing them on Odin?
Many thanks!
Yes custom ROM's are community made. The kernal is kind of like the foundation that sits beneath the ROM, so you can use the official ROM but run a custom kernal to tweak phone behaviour.
Flashing ROM's involves using TWRP instead of Odin. If you're going down that path I would recommend you read very carefully and educate yourself, instead of just gung ho'ing it. Wouldn't want to brick your device.
It's also worth mentioning while you can flash an older custom ROM via TWRP, that doesn't downgrade your bootloader with it. Having a newer bootloader on an older ROM can cause issues.
Most custom ROM's are also made for G930F, while some also support the G930K you may want to make sure before flashing anything.

Definitely will be more mindful as rooting does involve some kind of risk of bricking my phone.
Wow that's great info, really appreciate you explaining this to me.
Something new I've learnt! :good:
Hello.
I have a Galaxy S4 (SGH-M919) running on android 4.4.4. (I can give you more details if needed).
I need to install an application (EHTERAZ) which is a Qatari government application that only works on android version 6 and up (or IOS 13.5 and up).
Q: Is there a way to make the application work on my 4.4.4 android ?
Q: if not, how can I safely and easily upgrade my android to a newer version? (can you give me a full tutorial or video link)
Q: how to choose an android version that is most suited for my S4 that won't make it too slow or drain the battery too fast ?
Q: will I loose my files during this process ?
Thank you so much for your help, I really appreciate it.
It's the app developer who defines what Android version at minimum is required to run the app.
Upgrading Android requires phone's bootloader gets unlocked ( you lose all your data when doing this ), then a Custom Recovery ( what must be at 100% suitable to the phone ) gets flashed and finally via this Custom Rrcovery a Custom ROM ( what must be at 100% suitable to the phone ) gets flashed.
Hint: Add Galaxy S4 (SGH-M919 to front of this thread's title thus mainly owners of such a phone get addressed.

thank you for your reply jwoegerbauer. I'm not familiar with the terms you used (bootloader, flash, rom) so I'm not able to perform this by myself. Is there any tutorial or video you suggest I follow?
Greetings,
I succeeded in installing android 6 on my S4 and I made the application work fine.
I first installed twrp (twrp-2.8.7.0-jfltetmo.img) using Odin on my PC. I used twrp to wipe my stock system and to install the custom rom (cm-13.0-20161218-NIGHTLY-jfltetmo), in addition to Gapps (arm-6.0-pico).
As simple as that.
The latest twrp and the latest LineageOS that are (allegedly) compatible with my phone and listed in their official websites don't work on my phone, so I had to find older versions to make this happen.
Hi
I've been trying to downgrade my S8 from pie to oreo or nougat and no matter what I flash in odin the device stays at android pie.
My goal is to downgrade to oreo or nougat in order to get access to the OEM Unlock button in the developers menu which is nowhere to be found on the current pie system, from then I'd put TWRP and a custom rom on the phone... if I can get this far.
Thanks for any help

What model is it? Post a screen shot of it in download mode.
You can still root on android 9 ( Pie )
Downgrading is generally not possible due to Bootloader version numbers.
Generally in the past people have used the date method to to get bootloader unlock option in developers option.
There are many guides out there to do with this.
ie:

Note: Being on pie unlocking the bootloader in developer menu does not necessary mean that the kg / rmm has change. You can check in download mode.
Backup your device before hand.

As far as a picture goes, here's one of the download mode.
It's a SM-G950W, Canadian model.

I don't own a snapdragon version model and haven't kept up with threads involved with them.
The snapdragon (US) variants U/ U1/ W you cannot unlock you bootloader. So any conventional means of rooting/custom roms can't be done.
If there is any possible way to root your phone check out threads by extreme syndicate, jrkruse usually found in Samsung Galaxy S8 roms,kernels,recoveries & other threads but i don't like your chances of rooting/custom roms your phone on Android 9 ( pie ).

This is the general consensus I have been determining through my queries online that it's either not rootable or will take more skill than I have to do it, it's unfortunate too. The S8 with its original firmware on it is basically a dud to me because I detest samsung's software.
¯\_(ツ)_/¯ Oh well... Move on.
Hello to all and thank you for your time.
I recently bought a T-Mobile GM1915 version of the 1+7 pro, currently I have it network unlocked, and have just received my bootloader unlockcode.bin file from the OP website via email and am ready to unlock bootloader.(have not yet unlocked bootloader but I do have that capability)
Currently at this juncture I'm unfamiliar with what my steps might be or what my options are available to me that will allow me to pursue:
A) converting from the T-mobile Oxygen firmware to the Global Oxygen firmware version and establishing root access via Magisk with Gpay capabilities.
B) flashing TWRP to help with installing a stable custom ROM based on Android 12+ and establishing root (or root with Magiskl) access with Gpay capabilities.( This option is my preferred goal. But not a killer)
I'm open to changing my 2 prior goals if better solutions are presented.
Links to any threads that help answer my questions are very welcome (I'm not opposed to reading through any tutorials, walkthroughs, or stickies.)
Any quick and easy answers are useful as well.
AND thank you in advance.
(To recap: I have a..
T-mobile OnePlus 7 pro Gm1915
I have THE network unlocked
I have received my bootloader unlock code.BIN (but have not used it)
Current firmware-
Oxygen OS 11.0.1.8.GM31CB
Android vers. 11
I'd prefer to upgrade phone to a stable custom ROM or established root on a firmware other than Tmobile's (either custom or stock)
Again Thank you for your time and responses

Hey there, I own a Oneplus 7 Pro GM1915 as well and while I've dissected virtually the entire Internet and have obtained literally dozens upon dozens of TWRP guacamole.img files, patched boot.img, rooted patched boot.img, and let's not forget the recovery.img and enough custom ROMs of every make imaginable, that my cat actually said, "Meh." But not a single one was a perfect match to the T-Mobile Oneplus 7 Pro. Any chance you've had a little luck and have a LineageOS or a RROS laying around, huh?
Hello members,
Myphone: Galaxy A13 5G SM-A136B
I would like to use a 64-bit Android OS system with this phone.
The factory ROM is 32-bit.
I need a complete installation guide. And custom rom, custom kernel.
No one uses this? I won't choose another phone.
sorry i got one as a present but even thought i used weird aliexpress brand before (and acer) even though they had no guides i could follow the mediatek chipset guides more or less i hate brands like my first dvd player from sony complaining about region locks. I never had that before on the cheap stuff (just saying mainstream brands are usually more trouble and for more money.) but tried many of the same generated guides that say backup your phone before you start( i like that idea but before you can really backup you need root and fastboot seems to be non funtional these days cant we just mount a stock firmware img copy our needed root files in it and burn that like it is stock?) those img file are basiccaly just partions with files on it on intenal flash mem. at least i learned how to flash stock firmware after many failed root attempts and boot loops. i hope you find your info
