Optimus lg 2x S/W upgrade brick

Hey what's up! I'm having a really big issue with my Optimus 2x. I tried updating it using an online guide and using a program called KDZ FW UPD EN something like that.
The update didn't work and I'm stuck with a frozen screen that says S/W Upgrade, please wait while upgrading...
I have tried the hard boot, where you press the top button and the down volume button but when it takes me to the reset screen I cannot choose an option.
I have tried using the flashes as shown on the forums but I'm not sure if I'm doing it right. I've seen all the posts, but I don't quite understand what to do. Could someone PM me? I'm a complete noob at this.
Do I need another program to do Flash?
How do I hook up a bricked optimus to the computer and flash?
Do I still use the lgmobile update to flash/sync with the computer? If so how?
Could you possibly walk me through the steps, if you have time on your hands. My phone is my only way of communicating with my family in another province.
Thanks!

I keep getting stuck when it is actually installing. After the download section the updater crashes.
My phone can't do anything. I know I turned on the debug mode before the brick happened. All that happens when I turn on the phone is it says "S/W upgrade please wait."
Any suggestions?

Hello!
Follow the guide step by step...
Pull the battery push volume down and connect phone to your computer - now it says S/W Update please wait - and if everything (all the drivers) are installed correctly the Smartflash/LG Updater should see the phone and you can begin flashing.
If you phone isn’t seen by the software almost probably the driver isn’t correct.
Look here for more details...

Or try Rustys method for Disaster recovery…
http://forum.xda-developers.com/showthread.php?t=1229407

What ever I try it freezes on the UPDATE portion of it.
Before it used to freeze at 4% but now everytime it gets to update, it crashes.

Hello!
Did you try Rustys method?
What crashes? Your PC or the phone?
Did you use LG Updater, Smartflash or NVFlash?

The updater crashes. I did the flash with the KDZ. Not sure which one it is.
The updater crashes.
And on my phone it is stuck on the S/W upgrade, like it doesn't go past that even when booting up normally.

Hello!
Ok then...
You should try Rustys Disaster recovery first.
...and than one of the other methods.

hello..
do u have install cwm?
if yes,try boot to recovery and flash new rom

As I understand he is stuck in the "S/W upgrade please wait."-screen and can't boot in any way - doesn't sound like he has cwm installed...
As I already wrote he should try to flash Rusty Disaster recovery first (contains cwm) and then try to recover from there.

I checked out rusty's disaster thing, but ummm what do I exactly do with it. There is no real explanation about what to do, could you walk me through it perhaps? ^^ thank you again.

Hello!
Just follow Rustys post...
Start „flash-recovery.bat“ choose either internal or external SD card and flash it.
Since you surely don't have a nandroid backup I would choose external and do backups to external card in the future...
After that you should be able to get in to recovery and flash other roms you put on your SD card.
BTW: Don't forget when you use any of the flashing tools with Windows 7 you need administrative rights to do so – same goes for the LG Updater by the way...
Just right click on the batchfile (.bat) or smartflasher and use „execute as administrator“. Hope you find it - it says „Als Administrator ausführen“ in German...
If you want pure stock you could stock use this method with smartflash...
http://forum.xda-developers.com/show....php?t=1327929
If you want a pre-rooted version use this...
http://forum.xda-developers.com/showthread.php?t=1327949
(the Update.zip is flashable through CWM-recovery – just put it on the external SD card.
If you want to flash CM7-KANGS don't forget to flash gapps too...

How do I go about executing the flash-recovery.bat?
I hook up my phone, it turns on to S/W upgrade. The computer recognizes it, and then I open up the flash-recovery.bat and nothing happens when I tell it to do the external thing. The window just closes. O.O
Am I doing something wrong? Am I supposed to place the flash-recovery inside something? Like an external sd card on the phone or something like that?

Have you root permissions?

Hello!
Ok, still sounds like a communications problem between you computer and you phone.
You should try to use the command shell to start the batch-script to see if there are any error messages.
Do you use Windows 7, Vista or XP?
If you use Windows 7 look for PowerShell(x86) - you find though the start button - just punch in "shell" and it should show up.
Start it with right click of the mouse and use administrative rights!!!
Extract the files from Rustys disaster recovery package to a directory on c: - some thing short like "t" or "recover" and use the cd command in shell to get in the directory. Then start the batch script - type "./flash-recovery.bat".
Of course don't forget to connect the phone before the usual way - disconnect the battery push volume down and connect it via USB.
Now it should flash or give you an error message...

I had understood that he has to flash only recovery, not the firmware

Hello!
Well he had problems flashing the Update and now the device seems to be bricked.
The suggestion was to flash Rustys disaster recovery and try to flash a new rom from there. Right know he is stuck in a device only showing the "wait S/W-Update" screen...
He also could try Smartflash and flash a new firmware stock or custom whatever...
Again - right now he is stuck with a brick.

If u r using stock rom & bricked whn doin update, try LG online recovery its in update application in situation update not successful it phone gets bricked.it simple process.

If you lost recovery, download mode and fastboot, the only way is the fix hard brick tutorials (no fix for D415 yet as far as I know tho):
http://forum.xda-developers.com/lg-l90/general/guide-unbrick-hard-bricked-l90-variants-t3173429
If you get fastboot you can flash TWRP and then flash a bootstack for your phone model.

I ve tried it and it is not working, there are too many unclear thing on how to connect the points, even tho I did connect them with a metal wire (nickel wire not sure if that is bad) I saw no answer from my pc when plugging it in
I might try again at some point with a friend it was really hard to balance the wire on the 2 points alone and also plug the usb without moving it :S
thanks for answering though

HELP!!! Please! BRICKED!!!

Hey so I have the L90 D415 and I flashed the partition tool to get more data but i didn't realize that it was broken for my device and now im having issues.... This is how it went. I used the tool and it got to 70% and rebooted back into twrp so i knew that wasnt right so i flashed the next one that was supposed to be fixed and it did flash completely but for some reason it erased twrp, installed cwm and now i cant get into either. I had flashed stock using cwm before i chose to reboot but im still not able to boot up(stuck on LG logo). So to recap I can't get into recovery at all. I have fastboot. flashtool wont work(wont read phone in usb mode cuz im not booted) and im stuck on the LG boot screen. Please help me.

Well duh you didnt wipe the data of the rom before you flashed so of couse you are gonna be boot. Flash with the kdz offline flash then when you are done flashing pull out battery and use special button combo to factory reset it so that you can boot in to phone but you will lose all data excluding the ones on your EXTERNAL sd card.

You need to make sure that you have hidden files on

yeah i figured it out with google.
I have tried both methods on the guide and have came up short both times. I keep receiving this error(In screenshot).

I am desperate for any fix to this problem. I have access to fastboot and download mode. That is honestly all i got. When my phone is on the LG screen my computer reads it but the lg flash tool has connection issues. Please help me figure this out. I really need my phone back.

Go on the lg website and find lg l90 d415 drivers and install them if you got that far its most likely just driver issues.

Also check if you have your computer enabled for all drivers..
Some drivers do not boot because the certificate is not correctly assigned.
If you have a PC running Windows, on boot press F8 and select disable driver certification verify.
Try again after this.

LG G Flex F340L Korean variant bricked

Need help to unbrick my LG G Flex F340L software version f340l20b. It was rooted using towelroot. later I installed SuperSu app. But due to this OTA update was not installing. once downloaded during installi it was giving an error like "Your device is suspected in rooting. System update is not available for rooted device".
Later I installed flashify app from play store and tried flashing CWM recovery. Once recovery installed, phone tried to reboot to recovery where I got Secure booting error message. But the most terrible thing happened immediately after that. During that time OTA update downloaded once again and started installing. immediately after reboot, my phone is stuck in below screen. Now that its almost 3 days, my phone is in the same state. Even if I connect it to PC, though it seems that the phone is switched off, in PC I can see quite a few disk drives prompting for formatting those.

Thanks for sharing similar experience in a different thread. I installed CWM in my LG G Flex f340l20b. Once after that, while OTA update getting installed, my phone gets into this situation where there is no download/recovery mode, only LG logo comes in the screen along with security error. phone is getting detected as qhsusb_bulk and getting too many disk drives asking me to format those.

Thats method is too clear.
1) U need 10 files aboot, boot, laf ,dbi ,sbl1, rpm, tz modem, recovery, misc.
U can extract these file from tot or kdz using lg firmaware extractor.
Note....kdz doesnt have misc file and it doesnt matter so dont worry
2) you need to install qualcomm driver and if yellow mark then disable digital signature enforcemt.
3) copy these file to unbrick very partiton tool folder.
Note..
If u extract these file from kdz or tot then these file files will be in .bin format then you need to simply rename the extension from.bin to .img
4)
See the disk managemet on your pc and find which disk no. Your phone showing.
If showing disk then run 1hardidsk.bat/exe
If it say disk2 then 2hardisk.bat
5)
Keep in mind.
D802 d800 d801 d805 d803 all have same partition table for these 10 files.
So if u dont see any model in the kist choose d800 or d802..
After its says continue close the window
And swithc off your phone by long pressing power button for more than 15 second so that phone turned off.
After turned off press and hold vol up button and conncet to pc.
If you stuck in download mode screen and didn't get firmware update screen
Then do this trick.
Switch off.
Press and hold vol up and connect to pc.
As u see download mode scree.
Keep pressing vol up many times
Around 30 times.

Can anyome help me please? I bricked my Lg L90 P405n after choose bad recovery.img file. Phone is dead, when i connect it to the computer, i see Android USB serial device and one drive with etc 60MB capacity.
I tried some advices from forum, but nothing was succesful.
Now i see phone as QUALCOM USB .... device , but when i set boardiag and click on Start button a see message Failed during loading flash programmer, Test aborted when i choose G2MLTE (MSM8926) and Device was not found in dload trying flash programmer when i choose W7 (MSM8226).
Attempts over LG Flash tool ended after 4% with error communication with the phone.
Have anyone correct method for D405n and correct MBM files with partition.txt?
Thank you
Martin

Did you choose the right Com Port in b2b?

Yes i choose correct one. Today i make some other things and now is phone functional, but after restore phone lost IMEI information.
I use advice in this post http://forum.xda-developers.com/showpost.php?p=61636749&postcount=34.
Next question - is some way to restore/fill IMEI ?
