Hi everyone,
first thanks everybody for making this forum my daily resource for news about my P936.
I tried almost every available ROM from Stock ICS to CM10 and Liqiud Nitro but everytime I got BSODs and random reboots. My device probably has a hardware problem, so I need to send it to LG for them to repair/replace it. That's why I need to unroot it etc. The .kdz file under the csmg-link seems to be unavailable and all the mirrors I checked already deleted the file - so my request is for anyone who might have the file:
Please upload it to a freehoster and help me out. It's greatly appreciated.
Thank you in advance!

Just install the official LG updater and let it install the proper ROM. If you're having a problem with it, it's probably because you didn't remove the line you added to your hosts file when "unbricking".
If it won't let you update, install the v18f ROM (the one that comes as an EXE) first, then try the updater again.
found it
I found out how to download the exact .kdz file for your phone (directly from LGs servers: Exchange IMEI with your IMEI:

If you get that error trying running on an XP machine. Or if you have Win 7 prof or above run in virtual xp mode. This is a known issue with win 7.

Yes there is. I tried this on Win 7 & Win 8 and it only worked when I ran it on an XP box. Even setting compatibility to XP on Win 7 or Win 8 wouldn't help.

It's more complex than that. It works fine on Windows 7 for many people, myself included. I'm not saying people aren't having issues with it, but to blame the OS is oversimplifying the issue. There are a million other possible causes.
The only only thing I haven't tried to do to get it to work on win 7 is to reformat and reinstall windows. I really would like to know why a lot of us are having issues with win 7. I know win xp works 100% . I am not exactly a newbie when it comes to computers with over 30 years experience including 20 years as a tech and it has me stumped. I would really like to get to the bottom of this. Also I would add that I have only tried this on AMD based computers when I get a chance I will try it on an Intel. But again it is just a guess.

Sorry for the late response. I followed the unbricking guide. flashing kdz's is almost always the same. Your phone doesn't have to be rooted. Just have the shttps server running and your hosts-file adjusted like the guide says, that should be sufficient.
Does anyone have any advise where to download latest P936 firmware? That link doesn't work for me with my IMEI - it only give back some UML file. Maybe this is just because of my imei - my phone is just for some testing purposes. Can anyone try it? Thank you!

Hi, I was searching info and I found this, i don't know if can work to solve the download mode problem reflashing the firmware. http://www.lgmobile.co.kr/lgmobile/front/download/retrieveDownloadMain.dev Where it says Optimug G Pro Upgrade, click in the option "U+" that is the AKA of the F240L. I don't understand the characters, it seem korean or something like that, but there it is a info about the LG Suppot tool, i think with this program can download the tot file or flash directly with an internet connection.
I was searching for a kzd flash for lg optimus g pro series but i can't found a easy software tool for this purpose. But in this link is the KDZ Firmware files for your version http://lg-phone-firmware.com/index.php?id_mod=25

You just destroyed your firmware, hope you back up your phone regularly because every data on that device is now gone. On the brighter note, since you know how to flash the rom, all you have to do is flash the device correctly and you should be good.

First of all,i want to say Hello to all community!
I`m the new owner of a lg optimus g.I`m from romania and i have instaled V10H firmware(i think are last,no?)
So,i have a few question for you guys if you wanna help me.I search,and i flash the firmware and after i root the phone.But after a restart,when it boot on the screen was appear "Security error" and phone turn off.So,my first question is:I can`t root the stock rom?
Thanks very much guys!
Hi.
No there is already 10i, but we don't know changelog's from LG, so probably nothing significant.
What method have you used? Root this phone it's very easy and you can find a couple of methods in development area.

10i version mentioned here: http://forum.xda-developers.com/showthread.php?t=2602193.
I don't know if KDZ is available but you can search in XDA or google. Maybe it's better to stay with 10H.
For update I've used several times KDZ_FW_UPD with no issue (follow this: http://forum.xda-developers.com/showpost.php?p=44874388&postcount=36)
I've used the zv9-ZVB-Universal-Root (attached), because it was necessary to changed the bat file, unlock bootloader is afterwards with FreeGee.
What is the version of your phone? Are using the right kdz?

I find the 10I kdz but not for my country.For a few others,maybe i will recive later.Yes,i think now i stay with 10H version.
To clarify me,for work root,it`s necesary to have unlocked bootloader?Or unlocked bootloader it`s my option after i rooted it.
With the files you give me for root i must follow the same procedure?Run CurrentRoot with phone in Only charge mode,after that change to MTP and Enter?
Thanks for the file and topics,are really useful and what exactly what i want and i don`t found.
EDITn lg firmwares official site on my country i have the V10H version.But now i download the lg official firmware,enter the IMEI and the app give me V10F version.And now i check the lg site again and V10F version are last for service provider where i bought the phone and V10H are without service provider name(EX:V10F for Orange/Romania and V10H for Romania).Can be this a problem?
No. Root is independent from bootloader, but to unlock bootloader with need to have root.
Yes, that is the procedure to run .bat file. .
I'm not sure about your country, is your phone from Orange/Romania? I think that you can install 10H, but not sure wait for other user confirmation or install 10F to test...

I understand.Maybe first i did something wrong and that give that security error.I wil try again.
Yes,it`s from Orange/Romania,was a network lock phone but i decoded it with IMEI.I have the V10H and runs well,a just ask about the V10F version cause the Lg official firmware app show me that version to be the last and i think can be a problem with compatibility and that give me Security Error.Thanks very much for answers and for your patience
I´m new too.
I flash the rom again,and root it,restart a few times and works.But,after i unistall with Titanium Backup some apps who don`t use(google movie,books,music,lg note,email,smartshare,cell broadcast,google+,youtube,chrome) and restart,again appear the error with Security Error and phone don`t turn on.I don`t know,are something to do with root or are some apps that must don`t be unistall.But i didn`t unistall any other system aplications.What did you think,sir?
For sure it's an application issue, my advice is to google about system app that can be uninstalled.
You can also uninstall one by one to identify the ones that gives you security error.
Don't forget to do a backup first!

You can return back to stock with this usefull guide http://forum.xda-developers.com/showthread.php?t=2388440 (it works very well especially if you have a kdz>1GB ) or simply with KDZ updater( you find guide there http://forum.xda-developers.com/showthread.php?t=2010624 ).
I coundn't find the way to change the stock video player (which is quite buggy, slow and no option for full screen) in web browsers in CM11. It would be gread if we could choose for example MX player instead. Is there any solution to this? Thanks.

About two weeks and a few days, I bought an LG-H815P (used - came in the box, with the same IMEI number and voucher) Stockrom with root, as I could not upgrade because of root, I decided to install a modified rom. Then my problems started: the device had the message [secure boot error / error code: 1002]. So I decided to install a new stockrom, I downloaded the LG site, tried it first with [LGMobile Support Tool], it did not work I did with [LG Bridge] as the program itself sent. By an unfortunate distraction I believe I have installed the wrong version Stockrom. My device simply erased, did not give a sign of life. After following some tutorials on the internet I was able to recover it with [QFIL], I installed all the drives of the tutorial I followed, at the end of the process instead of going into download mode, it enters [fastboot mode] and does not leave it. I tried several times the procedure [volume up + plug the USB] for a second the image download mode appears, but soon it goes to screen [fastboot mode] and does not leave it, never.
Help Please

Hello, there is a program called LGUP. You can downgrade/upgrade android using this tool with your device kdz files. I would recommend to install same android version as it was before. Plus you can install custom roms only same android version as it was original. So i think that was the reason why you can't boot up your phone now.
Here is simple tutorial how to install and use this tool i mentioned before: https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
If there will be error during android installation i add .dll file to change with original one (its path: LGUP/models/ directory.)
I hope you succed. Cheers.

hi guys. Someone pls help me and provide me detailed instructions as to how to flash stock ROM. i have bought MI 11x indian variant. some of the xiaomi websites are blocked in India. pls provide me a link ( preferrably GDrive or Media fire) to xiaomi mi flash tool for flashing stock ROMs and official stock ROM download links. i want to install custom ROMs( in 2 days bootloader unlock tool timer will expire and i will be able to unlock bootloader). so i want to know how to revert back to Stock ROM just in case something happens when flashing custom ROMS. How do i flash firmware only? and also do we need any authorisation to use mi flash tool to flash stock ROM?

Sorry fella, I've not got Mi11x. Although I understand they're besaically the same device (i have poco F3), i wouldn't want to advise on flashing in case there are any differences... plus this is the first xiaomi since some years ago, so i'm a little vague too. That said i won't advising on flashing, you'll have to do your own research. What i am here for is to offer my mega account folder where i've uploaded MiFlash Tool, MiFlash Pro and XiaoMiTool V2. These are all the tools i am aware of.
i've included the other two not to confuse you but in the past i've found where one failed, another succeeded. eg the original MiFlash here has in the past failed for some reason (can't remember why now), so used the 3rd party MiFlash Pro, which also contains the MiFlash tool (not sure which version) under one of its tabs. That tool worked. Also XiaoMi Tool V2 is another 3 party tool for getting you out of trouble, though hopefully you won't need it!
No need to sign into your account to use these tools, even though it prompts to.
Also, when flashing with MiFlash, make sure you select 'clean all' at the bottom right corner, NOT 'clean all and lock'
here's a link to said folder with tools in it. Let us know if you can't use mega in India.
Also, let me know which roms you need from where for your device, i'll download them and re-up them to mega (assuming that works for you), failing that gdrive.
One more thing, in order to download your current stock rom, like you say, in case there's some issue, be good to know which build you are currently on...
this thread may be of use to you...
can you access this site for instruction?

unzip the tgz file TWICE to the root of C drive on your pc so that you are left with access to some .bat files and a folder containing images.
connect the phone in fastboot mode to pc and start miflash. click 'refresh' and check your device is recognised. (if you need drivers, i may be wrong, but i think when i installed miflash PRO, it installed neccesary drivers... use USB 2 port also)
select 'clean all', NOT 'clean all and lock' in bottom right corner of miflash
click 'select' and point to the extracted folder in C drive.
click flash. that should hopefully be it..... now, i'm pretty tired after a long night, but i think that's everything. can't remember, but phone will most likely reboot once completed...
give us a shout if you have issues or for steps on flashing custom rom... but all the info is here already in xda or youtube vids etc
