Step 1 - Search
Step 2 - Read
....
Step 4 - Profit
Seriously, the first rule of XDA is to always search before asking. This has been answered too many times to be funny anymore.

I know the other thread to rollback but result is bootloop the ics dont have stock recovery thats why i cant factory reset it

if recovery wasnt erased you can take the battery out, put it back in, turn on the phone and when the softkeys start to twinkle(be quick) press power+volDOWN to enter recovery from there flash a new rom, always before flashing remember to wipe data/cache and dalvik cache in recovery.
Try the new Echelon is great and LFD is gonna be updated next week.
i tried both these but i didn't make any resluts please help

Hmmm.... In my opinion its quite unlikely that the tutorial link i posted got no/bad results.
When Smartflash doesnt do the trick (asuming you did it right), well, thats bad
I got bootloops many times but i always saved my phone with the smartflash tool....

Yes, I was on froyo... missed this part when replied.
But I think it could do the job, even if he is on 2.3, well, that's what google shows when I search for "rooting android 2.3".
Am I wrong?

If you have unbrick your ob with v10a, yes you can root with Gingerbreak 1.20.

No, you can NOT root any v20/2.3 software/gingerbread on optimus black with gingerbreak. It only works on froyo, even if it s called GINGERbreak...
Sent from my LG-P970 using Tapatalk
method with smartflash tools :
* v10a + apk Gingerbreak
* v20x + flash superuser.zip from cwm

Okay, thank you!
Now let's be honest, this name is really confusing, right? Gingerbreak and only works with Froyo?
Maybe it's this way because by rooting your phone you'll be able to flash Gingerbread? hahaha.
Just sayin'.

You will have to go to the HTCDEV.com site and unlock your bootloader in order to root now that you have the ICS update.

If you just want to root your stock ROM, then you can simply flash su-3.0.7.zip from recovery mode instead of flashing a custom, rooted ROM.

[Q] Unlock bootloader to flash new rom?

Hey guys!
Found my old xperia x8 and i wanted to flash a new rom.
rooted it and installed xrecovery.
do i need to unlock the bootloader to flash a new rom?
Or just for the kernel?
you unlock your bootloader to flash a custom kernel. Some roms are for stock kernel and others are for customs. What rom do you want to install? Also you maybe will need cwm and not xrecovery.

no,that means its risky to unlock the bootloader,you can install safely any rom that is for stock kernel,i recommend you gingerdx.

thats isnt standar (in fact i dont remember how the battery is at 2.1), it depends on many things but the battery life at gdx is very good.
installed gingerdx and it stucks at bootscreen
dont worry
can you enter cwm?
if yes factory reset and reinstall the rom
if not http://forum.xda-developers.com/showpost.php?p=35338935&postcount=2

ok dont worry,its just that you were so close..lol
be sure to follow the installation instructions carefully,lets find what you did wrong the last time, did you factory reset before installing the rom? Also check the baseband number this time.
nope, didnt wipe.
just installed cwm, flashed rom, and got ****ed^^
downloading the stock rom where the 015 BB is already installed

[HELP] A little help please?

Good day guys!
was wondering if you could help me with this simple problem.
I accidentaly Bricked my O2X by flashing incompatible Kernel.
now my phone won't boot and is stuck on the LG unlocked bootlogo.
So, is there any possible way to bring back my phone without reflashing ROM?
My current ROM is official ICS v30c
LG SU660
response would be appreciated!
thank you
Flash proper kernel if you have CWM. If not, reflash is requied.

After an update to last cm, cm recovery overwrite twrp. Is there a way to have twrp again?

That is probably because you enabled an option in Developer options, namely "Update Cyanogen recovery". Again, read instructions and you will know how to flash TWRP.

This is offtopic. Google the instruction, there are a lot of sites available which can help, I am sure XDA has a dedicated thread. If you do not like to read search on YouTube.
This is what I found after searching 5 seconds. http://www.androidbeat.com/2015/12/how-to-install-cyanogenmod-cm-13-android-device/
Now please back to topic!

Cmon man, like, there's a whole guide of flashing TWRP out there. Even in this Mi5 forum.
You should really put an effort to read and search before you start asking retorical question in a wrong thread....

You have to install TWRP, we have guide on how to do that in this section. Then just wipe stuff and flash this zip (+gapps).
