Hey guys!
I've a question.
Finally I've decided to unlock my bootloader.
Now I'm using stock rom, .42 firmware, -56 baseband, deleted bloatware, V6 Supercharger, CWM Recovery, etc.
So, if I unlock my bootloader, flash custom kernel/ROM, etc., I'll lose all data, this is clear.
But I'm already using CWM for locked BL, so when I flash a custom kernel, there is always a CWM Recovery installed, right?
And in that CWM could I use my current backups from CWM for locked BL?
Nope, CWM wont make a Backup of the Bootloader's Lock/Unlock Status.
P.S - I maybe wrong.
Yes, Backups are still there.
Thanks.

I am not sure if my question will make much sense. I know how to flash official firmwares, and also how to flash custom ROMs via CWM.
I have been running 4.0.A.2.368 (UK Generic) for a while now, with [email protected] #3 kernel and of course root. I did this because for the time being I wanted an experience as close to the original as possible, but with added advantages.
I now want to update to 4.0.2.A.0.42, but without
a) Formatting my internal memory and thus losing my game installations and applications (a lot of which were purchased from the Store)
b) Losing root access
I know I am supposed to flash 4.0.2.A.0.42 via Flashtool, but I wonder if this will wipe the memory and thus cause me to lose above mentioned data.
Is there any way to update without losing my data, files, installed applications and games?
Many thanks for the help in advance.
You can flash via flashtool and still keep user data.
Also flashing new roms via CWM is not a good idea, there is no way atm to flash basebands (radio) via recovery so you would be stuck with older baseband.

Great! As about root.. Do I simply re-root the device?
I don't suppose I have to re-lock the bootloader to update via Flashtool, right?

Just make sure you untick the box that says "wipe user data". You can use flashtool with an unlocked bootloader. And as you have an unlocked bootloader, you can re-root by either flashing doomlords kernel, or by flashing the rootedupdate.zip in binarys CWM thread

I have an R800i that is factory sim unlocked. It is rooted, using the zergrush exploit, but I havn't installed any recovery or tried to boot into recovery. Does this mean that the bootloader is unlocked?
Can I install a recovery using the auto installer method? (http://forum.xda-developers.com/showthread.php?t=1437840) Will this stop my phone from booting?, as I have heard that the recovery is installed on the kernal or something, and you need to flash a kernal to access recovery and boot up

If you have not attempted to unlock your bootloader, it is not unlocked.
But since you have a factory unlocked R800i, you can unlock your bootloader from here.
If your bootloader if unlocked you can flash custom kernels, and custom recoveries.
However, ClockworkMod Recovery is accessible from the auto-installer, and does not require an unlocked bootloader/custom kernel.
So if I use the auto installer, the stock rom will still boot. If I flash a rom from that recovery, will the recovery still be there afterward seeing as it is on the system part of the stock rom. Will a custom rom include the recovery seeing as it includes the kernal?
Hey Guys,
I want to try out cyanogenmod 7.1 on my xperia play. I still have a locked bootloader but clockwordmod recovery is already installed, so if something goes wrong, i am able to go back to my stock 2.3.4 rom. I think for cyanogen mod working right, i have to flash the doomkernel too? So what will happen if i unlock the bootloader, flash a custom kernel and a custom Rom and then apply the backup, i created before? Will i go back to my stock rom, stock kernel etc? I cant find an answer for this :/ sorry for Bad english, im from germany

Despite the fact that you have recovery, you can't use cyanogenmod on a locked bootloader. Cyanogenmod requires a kernel that is different from stock, and you can't flash a kernel on a locked bootloader.

Yes, i know about that. My question is, if i unlock my bootloader, flash a custom kernel, Flash cyanogenmod and THEN use clockwordmod recovery to apply my nandroid Backup, that i createt, before unlocking the bootloader and flashing all These things, will this work? So im back at my stock rom and stock kernel? I really want to try out cyanogenmod, but i want the option to go back to stock, if something is Not the way, i imagined. And i dont know, if the kernel is included in a nandroidbackup. Furthermore, i dont know if a Backup, created with an locked bootloader will work on a device with an unlocked bootloader too?

Sorry, I guess I didn't read your post in its entirety.
The short of it is yes, you can use the nandroid of a locked on an unlocked phone. The nandroid won't backup nor restore the kernel, that must be flashed separately. The kernel is such a small filesize, and the command is easy enough that it shouldn't be a problem. That is, unless you wanted to change kernels while away from a computer.

Thank you, this was really helpful to me so i have to download the stock kernel, if i want everything as it was before cyanogenmod. But thats not the Problem, i guess. I think i'm going to try it out after work, thank you for your fast answers

I'm not entirely sure, but I don't believe there are any stock kernels available. You can use an .ftf file with flashtool, as that sets everything to stock, then restore a nandroid after reinstalling recovery.

Ahhh thats a lot easier than the way, i planned to do this. Thanks

If you restore a nandroid from a stock ROM after flashing the cyanogen kernel your phone won't boot.
You would need to go back to the stock kernel before restoring. Problem is, you don't have a recovery in the stock kernel.
You could revert using flashtool, by flashing stock, then rooting, then install the locked version cwm, then restore.
Or after unlocking the bootloader before even trying cyanogen, flash DooMKernel, and make a backup through the kernel recovery. Then you can try cwm, and if you don't like it, flash DooMKernel again and restore.

My device is rooted and freegee is installed but there's no option for me to unlock my boot loader. It gives me the option to restore or backup few & to install cwm or twrp. If I install the twrp is my boot loader unlocked? & if so can I install a rom. Furthermore can someone explain the lokifying thing?
Thanks
The OGP doesn't have an unlocked bootloader. With Loki, we get around that so we can flash custom kernels which is needed for AOSP ROMs.

OK thanks a lot!! So basically if I have a recovery with Loki support I can flash roms?
Yes. but I would strongly suggest you only flash Roms made for the E980. Many people run into trouble flashing Roms that are meant for the F240's and so on.
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.
