I want to follow the guide below to instal CWM recovery on my Go ICS 4.0.4 build 6.1.1.B.1.10. However my phone's bootloader is unlocked. Can I still follow the guide or where can I find a guide for an unlocked bootloader?
Can I just relock the bootloader, how would I do that and what would the implications be?

Yes you can use it.
It really is for stock kernels, or custom kernels that do not have recovery in them, not necessarily locked bootloader.

Nope, however the charching led may not lit in offline charging.
I had this issue with my XP I don't know if it's the same with the Go version.
It's still charging I think and easy to fix.
Okay recovery installed. Did a backup in CWM but now can't locate it....

If you go to restore you wil see it or a list of backups you done by date.
It is located on internal storage, clockworkmod directory.

Actually selecting 'backup current rom' just reboots the phone. So does "reboot into recovery"
Any idea why the phone simply roots normally?
Anybody got recover X working a GO?

I bought the atrix 4G from Egypt so i guess its the international one
i already rooted it ....however i dont have a custom recovery installed
I wanted to unlock the bootloader but in the instructions it says i should have a backup first which means i need CWM installed first to make a nandroid backup
when i go to install CWM it says i have to unlock bootloader first
I'm confused about which step should be done first, unlocking bootloader or installing CWM?
Can someone please walk me through this?
Think about it for a secon. Even if there was a way to make a nandroid backup without a custom recovery (and there actually ARE ways to do it), how exactly would you perform a restore of that backup if something goes wrong with unlocking the BL and/or installing a custom recovery?

I read that you lose all your data and application if during unlocking the bootloader
i'm just assuming if it went well , i dont wanna set up everything from the beginning i just want to restore it
but yeah that's something to consider you r right, i still want to know which step to do first ?

You lose nothing by unlocking the bootloader. However the procedure for doing that might at one point make your phone unusable until you flash custom recovery and then some ROM (custom or stock or whatever). And that is where you're likely to lose data.
You don't need a nandroid backup to retain data though. Just back it up using TiBu.

In a nutshell:
make any backups using TiBu
download a fruitcake firmware you want (probably the same version you have right now)
unlock the bootloader
flash custom recovery
flash the fruitcake
boot
restore TiBu backup

Hello,
is it possible to relock bootloader after ulocking it? I need it due to the warranty.
in short, No. please search the forum for details, as this is discussed.
i suggest you just try the luck sending the phone in and not mention anythong about the bootloader. of course should flash to stock rom if that still can be done

I think, he did not say he is sending to service center. He just said he needs it for warranty (in future).
See how smart these new pals are. May be we are all idiots to unlock it without giving a second thought. lolz
I do not have yet any fault, I just want to try alternative rom and I want to have way back to stock rom
My last phone had after 3 month of use some problem and I must return it. So I just want to know if it is possible
I thought that flashing the stock u-boot & x-boot will re-lock the bootloader.

Maybe this should be in a sticky post somewhere. I have seen a few people ask about re-locking the bootloader.
If this works, we should start collecting u-boot & x-boot images.
There is no way to relock bootloader. Here is good post about bootloader and omap4430, it applies to L9s. In our case ics xloader ,uboot or both simply don't recognize that bootloader had been unlocked and it just appears locked.
I see. Thanks you.
So, you guys with unlocked bootloader, have no problem with fact that your devices have no warranty?
If you don't mention the unlocked bootloader to the customer service and your device has an unrooted stock ROM, there is only a few chance that they check the bootloader if it is for an hardware issue.
It only requires a little bit luck .

cwm requires unlocked bootloader
I think you need to install the "CWM Recovery" bootloader to flash a custom ROM. And with a locked bootloader, you can only have a bootloader signed by LG (not a "CWM Recovery" one).
However, you can try this : http://forum.xda-developers.com/showthread.php?t=2095825
It is a "CWM Recovery" which is not directly placed inside the bootloader (instead, it adds a step on Android start). When I tried it on my P760 (when it still had a locked bootloader), it failed (but you can still try).

Actually that recovery will not work on jb,
Ok, that's why it failed for me.
Now, you have your answer, you must stay on ICS if you wish to keep your bootloader locked with CWM Recovery.
However, I would be curious to know what happens if a JB ROM (custom or stock) is installed through using this "locked bootloader CWM Recovery".

I received "Security Error" when attempting to boot when I tried this a while back. It just won't work because the kernel needs to be signed by LG.

Since you have unlocked bootloader flash boot image of desired custom rom using fastboot and then flash rom and gapps via recovery.

You don't need to run an exploit to gain root.
Once you have an unlocked bootloader all you have to do is flash a kernel with recovery, boot into recovery and then flash SuperSU - more or less

Ya you dont need to root before installing Roms like CM,PA,etc. as they are already prerooted.
For safer side you can always flash Super Su.zip in recovery after flashing custom rom like CM,PA.

I don't want to open another threat but is there any way to root 290 (4.3) on my C6833? Do I need to go down first? My bootloader is still locked and I would like to backup TA partition firs just in case. So first I need to do is get SU in somehow to be able to backup TA. After that I will be rrady for bootloader I guess.
So is there any way to rot 290? I did try some methods but non of them works. I really need that GPE on me ZU. :fingers-crossed:

Back up TA

install recovery (look in the general thread for jackies post - read the unlocked BL thread) or flash the one in the rom if it has recovery

flash GPe ROM

You unlock the bootloader to enable boot custom kernels not made by Sony. If you relock it won't boot custome kernels because the bootloader is "locked" to boot Sony kernels only.
You wank kitkat, bootloader must be unlockedm and there is no real reason you will want to relock your phone.

PC companion is updated regardless of your bootloader, it will update without a phone being connected.
I don't think you can restore backups to custom non-tock-based ROMs with PCC anyway, you must choose stock(or custom stock-based) or custom ROM.
If you want to re-lock, you must use stock ROM and kitkat does not work with it.

I don't understand the question, what kind of jellybean work?
If you mean custom non-stock based ROMs like CyanogenMod than no.
The other day, I set about installing Cyanogenmod 11 on my Xperia Z2 D5603. I was already rooted on the stock rom 4.4.4 Kitkat 23.0.1.A.0.167. I used flashtool to downgrade to 4.4.2 17.1.2.A.0.314, rerooted it, and installed dualrecovery from this link: http://forum.xda-developers.com/showthread.php?t=2785598
But upon choosing reboot after flashing the custom ROM via TWRP, the phone went dark, and wouldn't turn on. The only response I got was a quick vibration every second or two if I hold down the power button. I could not access recovery either.
I was able to revive it by using flashtool to reflash 4.4.2 17.1.2.A.0.314. I tried the same procedure with AOKP ROM, which had the same result. After trying many different things, I realized that factory reset, or wiping 'system' under advanced wipe would cause this to happen. Flashing without factory reset either returns an error, or finishes, but doesn't actually flash the ROM (stock ROM boots)
How to I flash a ROM without this happening? Any help is appreciated.
Have you unlocked your bootloader? It doesn't sound like it.
These roms require another kernel and you need to unlock your bootloader to install it.
