[Q] Step by step unbrick - LG Optimus 4X HD

My phone is previously running v10e ICS
I accidentally forgot to unlock bootloader, then forward to install recovery and factory wiped + cleared every other things(aka pristine).
Then when I'm attempting to install rom, you know what happens...
So now, how can I go back to the state where I at least have stock back?
Then I can retry.
Please teach me! No need to simplify words, I can take'em.

I'm not sure why you felt the need to open another new thread when you already have one open in which this was being discussed. I guess this is what you get for not following instructions when you ask for help. I specifically told you that you would need to reflash v10e first - that wasn't for fun, it was to make sure that you have a stable, known-working platform to start from.

[Q] Can't update

Hi everyone.
I have an Optimus 2x, and when i updated it to 2.3.4 i could not use superoneclick to root my phone instead i found an answer on how to root it.
I needed to install cwm 5 and after that busybox and so on, and it worked, it was rooted.
Now i have a other problem, i have an update on my phone and when i click on installing it starts to reebot then it comes to cwm screen, there i'm stuck.
I have tryed everything there trying to update it but nothing works.
So now i am wondering if any of you can help me?
Got any idea what i can do to update or what i am doing wrong?
//Szander.
Ok, so now i did a recover so i get back my phone as it was before i installed cwm and tryed to update, it did work fine.
Until the update was done, then it stopped, and nothing i did worked the little android just stand there and looked at me.
So what now, i removed the battery and hoped for the best, now the phone would not bot at all.
After a few tears and a few swear words, i thougt about something, maybe i could use nvflash to get it all back as it was ???
I tryed closed my eyes and after a few minutes i could restart my phone and it loaded as useall, but the update was gone, ofcourse.
So now back to square one again.
Sigh (
Hi Szander,
So just to be completely clear, you're back at a perfectly stock 2.3.4 unrooted ROM and you want to root it, right?
Why not trying to follow cyanogen wiki to root it?

No.
I have cwm, and its still rooted.
What i want is to get rid of cwm so i can update to the latest update wich is v20q.
I have tryed this with recover but its only working on froyo, i belive i read it somewhere.
And when i recovered my phone then the problem really started, but thats fine now.
And as an plus is that now when i run LGMobileupdate tool its saying that i have v20q but in the phone it says that i still have v20I.
Weird.
I have read alittle more and (if i got it right) found out that i might just need to use smartflash on the phone via my computer to get rid of cwm and get a perfectly stocked phone again.
So can you help me please, hoping that you understand my problem.
Yup, as far as I know you are correct. To get your phone back to stock you need to flash a stock ROM using either smartflash or nvflash. I haven't done it so I can't guide you through it personally, but search this forum you should find the relevant threads easily enough.
If you have trouble finding it let me know I'll help you searching.
EDIT: By the way, thanks for Meshuggah, one of the best bands ever I should visit Sweden sometime

[Q] Need opinion/help on android 2.3.4

Hello there, I'm kind of new in android world and don't know yet what to do right.
Yesterday I updated my LG Optimus Black to android 2.3.4 (previously from android 2.2.2 if i'm not wrong) and in the beginning everything was fine, until a realized that it had a problem with the front camera (colors diferent from reality), problems sending sms (keyboards fails sometimes) and sending mms (i can't send some pictures and before updated my phone i can do it....).
I don't know what to do, one friend told me to check this forum to see ROMs to install, but i don't know if i wanna install a ROM or downgrade (if its possible) to android 2.2.
Someone can give me an opinion and explain me how to do this of installing ROMs or trying to downgrade the version?
Read my signature OR try a factory reset and everything should be fine.

It isn't a way to return to android 2.2?
Look into my noob how to, grab a v10a or any other, you had previously on your phone, take LG extract tool, extract bin and fls files, inject CWM if you wanna root, if not, leave it, flash with smartflash, perform a factory reset and you should be able to enjoy your phone again

I've downloaded LG extract tool and v10a, and i've tried to extract the file but it gives me a error
and i've give up...
But then i've found this thread
http://forum.xda-developers.com/showthread.php?t=1692191
and i don't know if it is the same and how to run cwm, i've searched for everywhere and it says me that i have to press - volume and home but didn't work for me... and then in another website says me that i have to install
sorry i'm a really noob on this thing :x
In my personal experience stock 2.3 is better than 2.2 and they both suck, what i would do in your case is to flash a rooted stock and then flash a new rom, there are a couple great in this forums, if you're too scared to do that just factory reset your phone, i'm sure it will fix your posted issues, to do this press menu soft key > settings > Privacy > factory reset, i must warn you, this will make you lose all your info so save contacts to a google account or something and save all your data not stored in micro SD.
About your last post you can't run CMW cause you don't have it

[Q] Installing ICS from CM7.2?

Hi,
Sorry if this seems like a dumb question - A bit confused from reading up all the info on upgrading to ICS on the p990.
Im running a volk custom kernel, and CM 7.2 - OS Version 2.3.7.
Whats the "best" way to upgrade to the new ICS? I tried running the LG software update but it doesnt go too well, fails after it tries to detect phone - even though it detects it initially.
Can I get the release that LG released with my setup?
Please advise.
Thanks!
Same situation here. I'm on official cm7.2 and would like to upgrade to ics. But don't think that useing official lg update tool is so good idea - it might brick your phone. It won't update to ics because you aren't running the official GB rom so lg update tool won't upgrade (correct me if i'm wrong).
Maybe the AIO tool would do the trick.
Anyways, people we need your advice!
LOL, use NVflash ICS rom like TG.
for me the best way is using the toolkit to install new partition, new bootloader and recovery
than boot into recovery and flash the room as usual
Thanks Wakata.
Much appreciated. I have tried downloading the toolkit but its always corrupt.. ill download the 7 zip format.
I take it that I will need to back everything up and wipe everything, install new partition, boot loadder and recovery(CWM??), then flash with the new rom and kernel?
I've also used the All-In-One P990-Toolkit to upgrade to ICS.
You can use 1. to backup your internal SD in case you need it later.
Then hit 4. to change the partition layout and after that 8. to flash the new unlocked bootloader. That's all.
Thanks again
Slight problem - I downloaded the 7z file, and extracted them, but cant seem to run the .cmd file? What am i doing wrong here?
scratch that last question.. for some reason the files are corrupt when i download them.. grrrr.
So I followed the instructions, and suprise suprise, I get an error -
Nvflash started
nvflash configuration file error: file not found
An error occured. Read above lines for details
Help please
Nevermind, I had a fiddle and flashed ics 6.0.xxx.. lets see how it goes. Hopefully I havent bricked it lol
Sorry, problem.
I first tried option 1, then 4, then 8.. after its all done, no errors - I boot the phone, and its stuck on the red LG logo.. I've left it there for around 10-15 mins with no luck? Help!
Haha, actually I figured it out. I did realise I didnt have a ROM! Doh! lol rookie mistake.
I downloaded this rom and kernel(1.4ghz OC) and its running pretty well, no bugs so far(touch wood)

[Q] LG P990 won't boot after flash! Pls Help

Hello guys,
I'm hoping to get some help here, since I've lost 2 days trying to flash my phone with a custom ROM.
The phone was running Official Android 4.0.4 Ice Cream Sandwich V30A, and I did the following in order to flash it:
After unsuccessful rooting attempts with SuperOneClick (stuck at step 7) I found another way, using nvflash, following these instructions. Somehow I thought I need to unlock the bootloader first, in order to root the phone, so I did that first. After that, I rooted my phone with SuperSU Root as described in this tutorial, and also installed CWM.
I thought that I was ready for the flashing part, and downloaded a custom ROM along with the right GAPPS, and followed the instructions carefully.
First few attempts I got stuck at the beginning of rom flashing process, than I found a solution, where I needed to delete the first line in the META-INF\com\google\updater-script file, then the flashing came trough, but somehow to quick I thought.
After everything was wiped/cleaned/flashed I click on “reboot system now” after which the phone should reboot into the new rom, but nothing happens, the phone acts "dead", it won't turn on, or boot into recovery mod. I was sure that I've bricked my phone, but luckily I was able to get it back on using the APX method with nvflash and boot flash.
But then the phone starts with the official ICS 4.0.4, as if nothing was flashed.
After another day of searching for a solution, I've found out that there are different partitions for different rom's, than I realized that I was trying to flash
Android 4.2.2 Jelly Bean on LG Optimus 2X via Avatar Custom ROM
LG Optimus 2X P990 to Android 4.2.1 CM10.1 Jelly Bean Nightly
Jelly Bean on a ICS device wich logicaly should run on a different partition, so I downloaded a ICS based ROM EAGLESBLOOD™ ICS "AOSP" 4.0.4_r2.1 and got the same issue when flashing, where I had to delete the first line in META-INF\com\google\updater-script, but than the flashing process went trough and seemed more genuine than before as it took longer to finish, so I was happy for a moment, and rebooted the device, and voila nothing...he's deaaaad again.
Can someone please help me to find out where the problem lies.
Thanks for any help, I hope someone takes the time to read this.
No one here to help...
Finally I've managed to install TWRP over CWM with AIO Tollkit, to see if the problem was with CWM.
The flashing process/time seemed similar, but the phone actually booted this time, but not into the new "flashed" custom ROM, but into the old stock one which should be wiped/deleted...
Dont worry too much....
Just use the All In One Tool Kit by spyrosk.....just wipe everything....as I suspect that all your partitions have been disturbed.....for the link for this tool, check my signature
Flash the one from JellyCream.... (it is new bootloader ROM on the dev section) or if you want the 4.3 based CM ROM, then find the one from tonyp....
You will loose the data on the Internal SD card....if you have a backup on the external, then restore form it....
Edit: Eaglesblood ROM is not supported by the developers as far as I know....
Finally
Thank you for replying/helping :good:
As it seems, it was a bootloader issue (ord/new). My phone has the new one, and I thought that the ROMs I've downloaded
Android 4.2.2 Jelly Bean on LG Optimus 2X via Avatar Custom ROM
LG Optimus 2X P990 to Android 4.2.1 CM10.1 Jelly Bean Nightly
EAGLESBLOOD™ ICS "AOSP" 4.0.4_r2.1
would run with the newBL, since they ware recently updated or made, and there was no clear info about the boot loader version.
Now after 3-4 Days of struggling, I've tried a ROM which is made and clearly stated for the newBL,ParanoidAndroid v2.6 "p990-2.6-14-newbl-tonyp.zip" and flashed it without any problems. I didn't have to wipe the whole internal storage with AIO Toolkit, I've followed the usual flashing procedure.:victory::laugh::good: the new rom looks awesome. I hope that I won't have any lock screen or random reboot issues, like before.
Now I'm gonna help a guy, who has the same problem.

[Q] Back to factory settings

I never liked cellphones and avoided them for years until I got a Galaxy Note as a gift. I gave it a try but after a year of minimum use I can safely say that it doesn't appeal to me.
So I want to sell it, but the problem is in my attempt to like it I rooted it and it seems like resetting to factory settings with a root may cause on a brick, so I'm wondering, what would be the exact procedure I have to follow in order to get it to be as it was on day 1?
Model: GT-N7000
Android version: 4.0.4
Root: SuperSU
I mention SuperSU because it seems like it has an unroot option on It's menu. Do I just use that and then search for the factory reset option and I'm done?
Thank you for reading.

Yes, you can simply unroot using SuperSU or you can flash stock rom, whole procedure for that is mentioned in dr ketan's thread, look fot it and as you are on ICS dont do any wipes on stock recovery, use brick safe kernel.

As far as I remember I never did anything like flashing a rom... to be honest, I don't even know what that means, but I'm almost sure I never did it (although I would like to know how to see what "rom" I'm currently running just to be sure).
I just unrooted through SuperSU menu and I'm wondering what's the next step. I thought just going to system options and looking for reset to factory settings would do it now that It's unrooted but

this quote made me wonder, are you talking about the flashing rom method to unroot or to the step I should do now? Do I update to Jelly Bean and then do reset to factory settings?
I'm a little confused.
Thanks!

Just go to settings and about and see firmware version, build number and Baseband version should tell you if you are stock rom or not( not sure though have been using custom rom for too long now). Wiping from Stock Recovery might brick it not the factory settings from menu. Yes, update to JB from system updates it should be available if you are on stock rom or using Kies from pc connecting USB.
