Dear members of XDA!
A few quick questions here:
If my bootloader remains locked from stock:
1. and I downgrade to a previous stock android version rather than 4.4, will I lose BE?
2. if I do lose it, and then flash the last stock version, will I recover it?
If my bootloader was unlocked, I know that I should lose BE, BUT:
3. if I install a custom rom, don't like it, go back to the latest stock, and after everything's finished, relock the bootloader, will I recover the BE?
Thanks in advance!
1.nope
2.you will lose only if you unlock BL.
3.if u have TA backup, you can relock BL and recover BE by flashing stock ROM and restore TA.

I just got my Arc S, and i want to check out few different custom roms. I was planing on rooting the device with Easy rooting toolkit, so the question is, how can i backup my stock rom and reflash it, if i ever need it for warranty issues? (Also maybe to get the official 4.0 update next year )
On my previous phone (HTC Desire) it was pretty easy, by restoring the Nandroid backup that i created after rooting the device. How about the Xperia? Is there something similar?
And while we are here, any suggestion for some stable custom roms for the Arc S? Thanks
If you only want to root your device, you can simply unroot the device.
But you don't really have to, when you update your device using PCC or SEUS, the root is gone.

If you decide to unlock your bootloader to flash custom kernels/ROMs, you have to relock it, when you want to update your firmware using PCC or SEUS.

And which custom ROM you like is your decision, but I'm still a CM7 fan.
I have root, if I want to return to stock ROM (without root) I can just use SEUS to update my phone and the root is gone?

If your bootloader is locked yes.
I rooted my arc with EasyRooting toolkit,
How do I know if my bootloader is locked or not?
Edit: I checked by the service info, it says
Rooting status:
Bootloader unlock allowed: No
I am guessing that means my bootloader is locked?

Yes, it is.
And if you root, it doesn't, mean you've a unlocked BL.
Btw, you can't unlock your BL using the official method.
If you still want to unlock your BL, contact Jinx13.
I'll be going on a trip to China soon and I need to unlock my phone. I have tried unlocking my phone with the help of this post, but unfortunately it didn't work out. I read that I need to be using the stock rom for the unlock method to work.
My question is: if I unlocked my phone on the stock ROM and then restored to a backup with Clockworkmod, would my phone still be unlocked?
Also does anyone have a link to good stock based ROM that I can use to unlock my phone?
Any stock based Rom will do it, even the plain rooted stockones. And once it's unlocked, it stays that way until you relock it. Flashing a Rom shouldn't cause you to relock
Hello!
I've spent quite amount of time reading but i'm only getting partial answers, the big picture is still unclear since there is so many possibilities.
Currently: 14.4.A.0.108 Kitslim evo, rooted, unlocked bootloader (official method), custom kernel (Doom), TA keys are backed up with the TA 9.11 program.
Goal: Get 100% Stock on 14.4.A.0.108.
I can't use TA as first because i'm already on custom kernel which would result in bootloop.
If i flash stock rom i will loose recovery and i don't know which options i have to exclude since there is no info about that when flashing from unlocked bootloader.
How can i get out of this mess?
Thank you!

Question: what do you want?
Unrooted stock rom or another rooted stock rom or ....?
if you want a stock unrooted firmware, you must use Flashtool, download firmware first and then flash it with this tool.
Otherwise just download another stock rooted rom, copy to your device, boot into recovery and flash it

Goal is to get into condition ready for warranty.
Do i have to exclude TA in flashtool options when flashing stock rom?
When relocking bootloder do i have to use BLU or TA 9.11 program method?

all explained here
restoring TA partition will relock your bootloader and restore DRM keys, but only if you unlocked bootloader the official way by Sony.
same here i have rock z1 l, want to return to stock everything with that step i will return ??
So I'm planning to switch carriers and I'm wondering how I can unlock my i747M locked to Fido that's running OctOS L 5.1.1. If I have to downgrade, how do I transfer all my current app data and pic's. Also, is it possible to keep the unlock if you were to update you phone to a higher version or install a custom ROM or install the nandroid backup you made before unlocking? Please leave me with some important things to know about while unlocking your phone if possible!
If the phone is running a 4.3 or newer bootloader, you'll have to buy an unlock code.
In order to enter the unlock code, the phone should be running a stock samsung ROM from sammobile.
I suggest creating a nandroid backup with TWRP, copy the backup to your computer, flash the stock ROM, perform a factory reset after flashing stock, unlock, flash TWRP, restore nandroid.

so, in a nutshell, i just need to downgrade my phone to a stock rom of 4.3 or below and just search up a video of how to unlock it using the keypad method?
than if i wanted to, i could use the nandroid backup i did before and flash it and still have an unlocked phone?
You cannot use the free method once the phone is running a 4.3 or newer bootloader because you cannot properly run the 4.1.1 modem on a 4.3 or 4.4.2 bootloader and the 4.3 or 4.4.2 bootloader cannot be downgraded to a 4.1.1 bootloader.
Before flashing anything, which bootloader is on the phone?

Sorry for the noob question, but how do i found out my bootloader?
If this helps, my baseband is I747MVLUFOB3
I actually just logged on to get similar clarification. I have an unlock code, but it does not work when I enter it using OctOS-M. Do I need to be on a stock rom to unlock? Can I easily jump back to a stock rom, then back again to a marshmallow rom?

From what ive heard, you have to be on a stock rom. As of google, even then, some users have problems or cant, which from what ive heard, can be fixed by downgrading to 4.3 (make sure ur bootloader is the same or your phone WILL be bricked).
Please note that this is from what ive heard and may not be accurate.
Install the Samsung phone info app from the play store as it will tell you a lot.

My boot loader seems to be the same as my baseband.
What is the bootloader version?

That sounds problematic...I am on NJ2. I am not having any luck finding anything about getting back to stock on the newest bootloader.

Do you think this one would work?

Whats a CWM anyways?
CWM is Clockworkmod with is a custom recovery. CWM is outdated as it has not been updated for quite some time. Many recent custom ROMs now require TWRP.
You may be able to software unlock the phone but you'll probaby need a UART cable and Samsung Pro tools. I don't believe Pro Tools is free.
The linked thread is from 2014 and, in 2014, many phones were running 4.1.2 which meant the phone could be downgraded to 4.1.1 using and sim unlocked using the dialler's menu options.
Phone is rooted woth twrp, unlocked bootloader and a custom pixel rom. I need to unroot the phone and lock bootloader if possible.
Anyone?
I think if you flash the stock OS from OnePlus' website and reboot it will install their stock recovery as part of the process and turn you back to stock so you can re-lock the bootloader safely.
