So was messing around with my d959 to get an app working meant for a variant d950g , flashed a few different roms no damage done beside having to flash a modem.zip I made myself afterwards to get service, cool, flashed the d955 rom and the LG flex has finally been bricked, cannot get service after trying multiple d959 kdzs/tots using LG Flash tool both methods no luck, I've concluded my EFS is corrupt, unfortunately didn't back it up pretty much stuck with a bricked 959 at this point?

Good luck buddy.

If you're installing a custom recovery then you have unlocked your bootloader which means your warranty is already void (If LG decide that you have done something to cause the problem).

Im not aware of anyone bricking this (non-DEV version) phone, LG's download mode is pretty low level, the kdz packages also contain a boot loader so you would find it difficult to irreversibly brick this phone
Thanks Lads i got it working

LG G Flex EFS Backup Zip
Background
The G Flex has no built in EFS backup partitions. EFS contains things like your MEID or IMEI... your data profiles.. radio settings. The EFS cannot be replaced... it is unique to your phone only... backing up your OWN EFS is highly recommended.
I have added EFS backup to the IOroot scripts so that everyone that roots will have a copy of their EFS partitions on the computer you run IOroot from. Regardless, this current thread will still be a good "heads up" and an alternative for those who insist on using other shady root methods or for those who just want another way to back things up.
I made a similar thread for both the LG Optimus G and LG G2... for reference the G2 thread can be found HERE.​Backing up EFS
Root is required!
In TWRP/CWM, flash the LG_G_Flex_Backup_EFS.zip attached in this thread. LG_G_Flex_Backup_EFS.zip is a flashable zip which creates a new flashable zip containing a backup of your EFS partitions and is saved in /sdcard/EFS_Backup/.
To manually backup EFS partitions without the zip you can use the commands below while in ADB shell. You can do this while booted in the rom or in custom recovery. If backing up EFS while booted in the rom I suggest placing the device into airplane mode first. And remember, root is required.
Code:
adb shell
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst1 of=/sdcard/modemst1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst2 of=/sdcard/modemst2.img
Backup your efsbackupflashable.zip or loose partitions somewhere else besides your internal SD!!!
Email.. "cloud".. PC..
Restoring EFS
To restore your original EFS just boot into custom recovery and flash the efsbackupflashable.zip in your /sdcard/EFS_Backup folder.
To manually restore EFS img files run the commands below using ADB shell while in recovery or booted up with airplane mode on...
Be sure to place .img files on the root of your /sdcard/(internal storage)..
Code:
adb shell
su
dd if=/sdcard/modemst1.img of=/dev/block/platform/msm_sdcc.1/by-name/modemst1
dd if=/sdcard/modemst2.img of=/dev/block/platform/msm_sdcc.1/by-name/modemst2

@autoprime is this the stock backup? Does this work on all variants of the Flex? The process of creating the back up. I assume it will.

not sure what you mean? both the G2 and the G Flex have partitions modemst1 and modemst2 for their EFS.

EFS is static across all roms.. there is no "stock." It is key to backup EFS ASAP before any corruption can take place.
And no assuming needed... it states it in the title of the thread that it supports all variants. Reading is paramount.

Thanks well do as soon as it arrives in mail. >.-
So by using the code you put in OP under "Restoring" is what I would use to restore the efs that was backed up from root process?

I had a rooted D959 that was stuck in download mode and would not for the sake of it take the proper kdz file and would stop at 45-49% when updating and never fully flash. I tried everything and ended up calling LG as a last resort and told them something happened during an OTA update and the phone would not start. Luckily they repaired it for me under warranty and I wasn't charged anything. The paperwork sent with the phone stated they replaced a memory module. May work for you. They also asked for the receipt to be shipped back with the phone but since I bought the phone used on EBay I didn't include one in the box and they still fixed it. Guess they know the phone is under a year old so they no need to know the exact purchase date for the year warranty. I was extremely lucky and jumped around like a little kid when I seen the warranty status website show the phone was fixed and being sent back at no charge, don't know if anybody else will be so lucky.
You may be in a better boat to get it fixed free as yours isn't saying saying ROOT like mine did in download mode. If you can't solve it yourself worth a last resort!
Can some one tell in detail how ro manually backup? What to do with these files?
How can I restore or fix a corrupted efs partition? Was told the efs partition being corrupted is the reason radio isn't working.
I had the phone all fixed, gave it back to the owner - He tried to do an OTA update to KitKat. Now it's stuck in a boot loop. This thread - http://forum.xda-developers.com/lg-g3/development/fix-stuck-custom-recovery-trying-ota-t2907508
Did not help. Of course, I'm probably doing something wrong. It boot loops to recovery, won't go to the ROM at all, and now there isn't ANY back ups. Also, when I try to flash that flash fix - It says phone is unrooted and it wants to install SuperSU.
Help for the last time? :/

that friend of yours cant keep his hands to himself can he?
remember you flashed a D958 tot to that D950. when he tried to OTA update maybe some partition didnt match.
If you still have the zip that I told you to download (Dfuses stock att) flash it through adb sideload.

All I had to do was...**** I don't even remember now. I entered a couple lines of code into terminal and that let me enter into download mode. Now I got it back up and running but it says radio off. The baseband and imei are all there, so I'll have to go into the hidden menu...? I'm not sure.

If you flashed the modified D958 tot then thats the problem. I suggest you use the original KK D950 tot. That way the phone will get the modem it needs to have radio on.

If radio is off lets hope the efs isnt damaged again.
Be sure to use the att tot cause you edited a D958 tot if you use that one the radio will not work ever.

Hi, recently i managed to brick my Korean F340L G Flex so bad. I've tried almost everything software wise.
-The solution:
I'm planning to change the logic board from a Sprint LS995 model. I think it will work ok. Of course I'll have to some how get an unlock code in order to use it in Greece where I live.
I've seen in ebay some users providing for a small amount of money this code.
So, what do you think. Will it work as I'm thinking? Any comments, suggestions, guides welcome. Thanks
Here is a short story:
"Hello, to all, I'd like to share my experience and problem with my LG G Flex, as a last hope to find a solution to unbrick it.
I know that the talk here is about G2's, but I saw many users reviving their Flexes with OP's method.
So here is what I did in steps:
1)I rooted my Lg g flex F340L
2)New OTA, downloaded, but failed to install after reboot. The message was no OTAs for rooted devises
3)Tried to unroot, but with no success. Still no installation of OTA.
4)Found, and flashed the stock F340L rom , (had an EFS backup), from another user here(.tot file), with LGFlashTool.
5)SIM card was not recognized any more (Greece, Vodafone), so no calls. Did all the updates, but no SIM, still.
6)Hard reset, still no SIM.
7)Decided to flash stock F340K kdz rom, and install CWR. All good, SIM detected, OTA downloaded, but after reboot stuck at CWM nenu. Whatever I do just CWM.
8)No download mode, or usb support, just an LG FLEX unknown device. Got some drivers only to be seen as lenovo ADB device.
9)I found the test point on the motherboard and short circuit it. Got a qhsusb_bulk(qualcomm 9008) under COM ports, but not on a specific port.
10) No flash capability, and no partitions to try and flash the 10 or so, images. Ubundu, no luck with the partition detection either.
11)After many reboots and button long presses the CRW came back...again
Well as I can see, there is not so much support for the korean variants and I might have destroyed my phone. So, I need your advise in changing the motherboard. I found M/B's from AT&T and Sprint variants, to install to my F340L. I think it will work. After I will purchase an unlock code from lets say ebay to unlock it to all GSM networks ( I live in Greece).
What is CRW or CWR?
Are you referring to CWM? The recovery?
If you can boot into cwm your phone has a chance to be saved no need to change the mb.
By the way sprint doesnt give out unlock codes like att. There is an specific process to sim unlock sprints variant.

Yes sorry, CWM I was refering to. Well, since I have no other option at the moment. I'll try to find that specific process you've mentioned when I get the board(help or hint welcome)
As, for the M/B change, no system partitions are recognized in order to flash individual .images to unlock them.
If you can access CWM you dont need to flash the .img files for your phone. Instead you could flash a stock zip through adb sideload or flash twrp through sideload too. Twrp allows MTP use so someone using an F340K can help you with a stock backup and you can unbrick instead of changing board.

The only stock image I have is in .TOT file for the L variant. I also have stock .kdz file for the K variant. I can sideload to /sdcard/0/ directory only, if that helps. I'll try to find twrp.zip and try it. But the main problem is to find stock rom in .zip format.

I previously had the LS991ZV5 update but I wanted to update. I was rooted so I did the full unroot in SuperSU and when I reset my phone, it was stuck. I went to install a firmware version. I accidentally installed the US Cellular firmware. I have tried all the threads I know of. I tried to edit build.prop to "trick" LG Flash Tool into thinking it was a Sprint model(which it is but the firmware wasn't.), however I messed up and now am stuck on the LG logo. This is my only phone. Is there anything I can do?

That's not how to unroot.
You have to restore the ZV5 image you backed up. You did make a backup right?
You can try to restore a ZV5 image (they are available for folks that didn't make one or lost it) or use the TOT process to restore it.
Look in the thread for TOT, Images, ZV5 ZV6 in developer forum. Everything you need is there.
Your phone should be recoverable.
Since you are still on ZV5 only use the ZV5 stuff until you successfully apply the ZV5 to ZV6 OTA Update.
