Dear all,
I have rooted my device which is running 4.3 (c5502) (build number: . 101) with towelroot. Now i need to install any custom ROM. I came to know that it requires to install recovery first before flash any ROM. I stuck there..Can you please guide me. I didn't unlock my bootloader yet but I had my TA backup with me.Thanks in advance guys.
whatever u need to know is already there. just search for it. if u expect to be spoonfed then you really shouldn't mess with your phone
The thing is, do we really need to unlock boot loader to flash custom roms, or can it be closed just with root and recovery?
No one tryed it till now I think.
Greetings.

Yes for flashing custom Roms the bootloader must be unlocked and a recovery must be installed however if you want to flash a stock based Rom unlocked boot loader is not needed. Just Root and Recovery needed for flashing the stock based Roms. Correct me if i am wrong.

I've been doing a lot of reading and searching but still can't find a definite answer...
My understanding is that I need to root the device to flash a custom rom
But from the instructions for noobs, they don't usually specify that I have to root
I assume that rooting is a pre-requisite for everything...but then some roms advertise that they are rooted (for example, LeoFroYo)
So it the rooting process tied to the rom itself and I have to root everytime I flash a new rom (if the rom is not rooted)? Or is it universal like HSPL on WinMo?
Rooting is per rom. What is required to flash a custom rom is having an unlocked bootloader and a custom recovery image. From there you can flash a pre-rooted rom.
The root instructions assume that you're gonna keep using the stock version with root abilities added on top. Whereas if you're using flashing something like CM, that already has root and OS tweaks.

Thanks! So does that mean when I get my phone out of the box, I have to root it once over the stock rom before I can flash any custom rom?
You need to root the phone originally and flash a custom rom. The "pre-rooted" means the rom is rooted. So if you flash that rom then you wont lose root. If you flash an un-rooted rom then you will lose it. So go through the steps and unlock your bootloader then flash a custom recovery image. Then decide which rom you wanted and flash it. All the custom roms are rooted.

That explains it. Thanks for your answer
one more question:
I take it as when bootloader is unlocked, there's no way to lock it again? Not even flashing the stock boot image?
No, once you unlock the bootloader, it stays unlocked.
Just to be clear here you don't _have_ to "root your phone once"
On _most_ phones you need an exploit to be able to get to the bootloader, this exploit is often referred to as rooting. After the exploit you generally have superuser access until you reboot, on some phone this may allow you to get at the bootloader and write anything you want there (E.G. an OS that give you superuser access at boot time)
However the N1 lets you issue the command "fastboot oem unlock" that unlocks the bootloader, from there you can flash a recovery image that will allow you to flash the main OS without having access to Google's release signing keys. Hence you _could_:
1. Bootloader unlock
2. Flash Custom recovery
3. Flash Custom OS
Without ever actually having "root" access, it just happens that most Devs prefer having root access available in both recovery and any custom rom they cook up.
Hi
Sorry for the dumb question, I dont want to root my phone (the Barclays app, I know it can be worked around) but do want to play with ROMS. All the instructions I've read say to root the phone, but do I have to to be able to put new ROMs on. Thanks a lot in advance.
Yes you obviously need to be rooted to unlock your bootloader, to flash a recovery and to flash ROMs

If you want to install Stock custom Roms like MagicRom you will need only root
but if you want to instal a Custom Rom like cyanogen-mod, miui you will need root and unlocked bootloader

It's true only if the rom doesn't have a custom kernel and most roms do. If the kernel changes, you need to unlock the bootloader. Also, you can't flash a custom recovery without unlocked bootloader.
Hi guys!
I have searched the forum and I DO have got a lot of answers. But still I want to get some things clear before I go on.
I just got myself an Xperia Z. It was already updated to 4.3 .569. The phone has a locked bootloader and I found out that it CAN´T be unlocked. So there I´m stuck.
I was first thinking about following this guide: http://forum.xda-developers.com/showthread.php?t=2590088
But then I got some more questions.
If I downgrade according to that guide... since I get a custom recovery, can I flash any custom ROM that is made for locked bootloader? Do I even have to use the 4.3 .569 used in the thread above or can I just downgrade and root then choose the ROM to my liking?
Thanx for all your help!

Dear friend:
1-the easy way::laugh:
2-Flash 4.2.2 with flash tool
3-Root on locked boot loader
4- Install Dual Recovery follow
5- Install 4.3/4.2 Pre-rooted or any other rom of your choice.
Once you've downgraded, rooted and have a custom recovery, you can use any rom you like, as long as it's a stock based rom for locked bootloaders.
You cannot flash anything based on CM/PAC/AOSP/AOKP etc as they require a custom kernel and therefore an unlocked bootloader.

I have followed the rooting, backup (drm keys), flash new firmware etc etc procedure. However every time i flash a custom rom and reboot it goes into brick. I mean no bootloop just flashing red led when on charger, i cant even get to recovery to restore.
then i have to do
Flash .105 kitkat stock firmware>giefroot>dualrecovery install.bat>flash new pre rooted firmware>try flashing custom rom again>BRICK>(return to start)^
i have unlocked bootloader, everything done, even when i try and restore drm keys i get bricked.
i have currently given up on custom roms and im living with crap camera, no custom rom.....nothing.
please help, send food n water
Help please
:crying:

Oh OK. Thanks for replying . Damn but my bootloader is unlocked. No idea what I should do.
Hi all. I would like to revert the phone to stock after root and custom rom. Ther's a guide? I can't find anything on the forum. Thanks at all.
I think you just flash the stock firmware over what you have.

Thank's! So, no warry bout unlocked bootloader?
You might want to relock it first, but I don't think it matters. I am not sure though. Just basing this off my time with the S3 and S4 back in the day. With those phones it didn't matter. The S10 line are newer so it might with them.

I presume you want the boot screens to revert to normal without the Bootloader Unlocked warning screen.
If so, see my post HERE

I am on lineage os (Ivan_Meler) not rooted
under the developer there is no OEM option showing. My bootloader is unlocked, recovery is TWRP.
how can i goo back to stock ?
Just to be sure: Before I flash a custom firmware on a S10(+,e) like lineage, there is nothing to back up like DRM keys or certificates? (I had SONY phones before. If you reverted to stock on those some SONY apps would not work anymore if you did not backup the DRM keys).
Hello guys,
Similar question what is the procedure when I want S10e with flashed custom rom (TWRP Recovery), rooted and unlocked bootloader to return to stock firmware?
