I've been using Samsung devices with custom ROMs for a while. Sadly my most recent purchase of a S7 obviously came with a locked bootloader and the eBay seller updated it to it's latest G930TUVS9CSC1 firmware.
I've looked around for guides and methods of flashing a custom ROM with very little trustworthy advice and links. I'm hoping someone who has flashed a custom ROM on the v9 bootloader has a method they can share.
The ROM I'd like to flash is this LineageOS build. Hopefully it doesn't affect cell signal and NFC like it did on my Note 3.

I'm just curious
If you flash this file : Stock-GT-N8000-leaked-KK-Boot.img-CWR-installer.zip on a tablet does it permanetly downgrade the bootloader to gt-n8000?
I'm just curious what are the pros and cons on flashing it on an older device like a gt-n8013???
I think its pretty safe to say samsung isn't going to release any newer oem roms for these devices or am I wrong?
Thanks for any help offered.
Flashing this boot.img is the only way I can ever get my n8013 to have WiFi on the new KitKat roms based off of the stock rom.
My phone has been bricked for months. I am trying this guide on xda: http://forum.xda-developers.com/showthread.php?t=2542219
So far all the stock firmware seems to not work. I am 90% sure my phone is US Retail but I am not sure if it is XT1032, XT1045, Falcon, Peregine, or whatever it is.... So I am confused as to which files I am supposesd to flash to return to stock; and where they are located.
I currently have access to the bootloader and have TWRP custom recovery installed but I don't know how to install the stock firmware. If anyone could help me understand which model my phone is / why my flashing isn't working, it would be more helpful than they could imagine... :good:
Other threads I made on this simply redirected me to that thread, but I can't find any help or related topics :/
Additional info: I strongly believe that the model number is the issue as I followed countless other guides on how to install Cyanogen Mod and a couple other roms since I got this phone brand new. None of the roms flashed properly, none of the recoveries worked, until now. All I have is a recovery left and a bricked phone...( + access to the bootloader of course)
For your Model number Check Ur Mobile Bill/Box...
Could you also look it up with the imei #? In case a box is not available

Thanks for the help, but I found the problem.
Opened the back of the phone to check the model number and it was XT1045 like I thought, so I had the right stock images. Problem was I did not have the Motorola drivers for mfastboot installed correctly. I used a guide to install them universally on mac and my phone is back up and running!
Hi all,
So I had a custom 4.4.4 Rom, on a JB bootloader because I can't install roms that have a KK one, says that device is not compatible.
The other day I changed provider, so I had to flash a factory rom so I can unlock it to accept new provider SIM card.
So basicly, now I have a xt925 with unlocked bootloader, but with an old 4.1.2 Orange rom, no more Recovery, and I guess no more root too.
Could anyone tell me (or point me to a web page, because I only found ICS->JB tutorials, KK tutorials with broken links to required files ) how I can do to have a nice KK rom, with KK bootloader and recovery ? (plus my actual rom is badly acting with my radio, I loose signal every 5 seconds or so, which is pretty annoying).
Any help will be greatly appreciated :highfive:
Thanks !
There's plenty of information covering your questions contained in the the "General" and "Q&A" forums. You're going to have to do some reading.
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:
Is there any custom ROM for H840 version? I looked everywhere but nothing shows up. I just messed up my phone, wiped everything from TWRP and does not have OS now.

Did you ever find a solution, mate?
Only H850/H830/RS988 ever had LineageOS builds. Obviously you can install custom recovery (TWRP) on other versions of the LG G5, but that's as good as it gets since you cannot unlock the bootloader to boot into a custom ROM.
If you're stuck without an OS on other variants, you're better off doing a full restore using the LGUP software tool.
EDIT: It seems the SE H840 can also be bootloader unlocked officially by LG, although people have posted mixed experiences depending on what "region" it came from. From what i've seen through searches, people have been asking for custom ROMS for the H840 since 2017 but nothing has come up.
Bump... Just in case anyone has come across an alternative ROM.
I unlocked my UK H840 without issue .. just need a new ROM to replace the old stock..
Any news? Would like to install an application that isn't supported on stock Android 7.0.
This is not the right location for questions. H840 will never have custom ROM support in all likelyhood.
