I will lose all of my data :(

Hello guys! I bricked my device, so it doesnt boot right now. I was on Cloudy Flex 2.8, then I wanted to flash Cloudy G2 3.3 (G4 ROM), but my phone was bricked. I wanted to solve these problems with SRK Tool. I did this option there: Unbrick - qhsusb_bulk 9006 (No Recovery Mode,No Download Mode).
Now, I can enter download mode, but afraid of entering recovery cause I think custom recovery lost, that's why If I try to enter recovery device will be factory reset. PC doesn't see my G2 Device gets "Security error" when boot. So, I dont know what I must to do. Want to back to stock but If I used to flash stock roms with kdz or tot methods after I must do factory reset And I don't want to do it. How can I backup my datas right now? And can I rescue my device without flashing stock Rom? Thanks in advance! Regards!!!

OMG Noone can help me :crying: Please, help me friends!!! I cannot do anything right now

Urgent help Required...!!!!

My device Lg E615 is in bootloop i am trying to reflash the stock rom on it...with proper usb drivers and flash tool everything is going well but at the start of flash tool it shows phone was not found
1. The phone wasn't rooted
2. USB debugging wasn't enabled
Guyz is there any way to enable usb debugging when device is bricked and its not rooted....plz help

Unfortunately, No. If there's a way to get into fastboot mode or firmware update, you could have hope of flashing a .kdz or .zip file, but otherwise no.

Bricked LG G2, download mode goes on, but not working

Hello
I'm new here, I've been modding my lg a few times, always when bricked, kdz or tot files were saving me.
But now I've got real problem.
I was changing ROM from Cyanogen 13 to Cloudy 3.3. I thought I just need to flash rom via recovery (2.8.7.3 bump blastagator). Flashed fine, without any troubles, but when it came to reboot, phone just got stuck on LGs logo.
I knew i f*ed up.
Recovery isn't working, but Download Mode is turning on normally, at least it seems to.
So i tried to flash KDZ, but LG Flash Tool immedently shuts down giving "lg user...." error (don't remember what exacly it was saying).
Then i tried via tot files. But after installing drivers from tutorials, device isn't showed as "LGE AndroidNet USB Serial Port", but as few positions like MTP device or usb serial port(but not in Com ports) and all are marked as devices without drivers. Flash tool for tot also didn't worked here, because it did't found device.
What can i do now? Please help me.
[Edit]
So now, using different drivers somehow Jelly Bean installed by tot method (device didn't appeared as tutorial said, but it worked) phone is booting normally, but i can't again install lollipop with kdz files.
I was trying 3 different drivers, every giving instant error of flash tool.
What can I do now?
[EDIT2] LGUSERCSTool.exe is crashing. How can I install lollipop now?
Are there tot files for lollipop?

LG G2 hard bricked, partition table lost and stuck in QDLoader 9008 mode

Hello Guys, I have LG G2 F320S (Korean Variant) and a few days ago it was stuck in fastboot mode while i was trying to upgrade to Lollipop firmware using LG Flash Tool 2014. And Fastboot commands were working fine but the problem was that some of the partitions had become write-protected so I was unable to erase or reflash those partitions. So, I short circuit the capacitor and I successfully entered Qualcomm 9006 mode with a number of partitions. I used SRKtool to restore partitions (I have this experience in the past so it was easy for me) but here I noticed 1 or 2 partitions were not restored (write-protected) but phone restarted to download mode. When I tried to flash stock firmware then it always stuck in the middle or something and later once again I was stuck in fastmode mode where I started.
I don't know how partitions became write-protected?
Once again I disassembled the cellphone and short-circuit the capacitor to enter Qualcomm 9006 mode and this time, I wanted to remove write-protection from these partitions so I opened "Diskpart" in "cmd" selected LG G2 and performed clean command and format it. Diskpart removed all the partitions gave me a 32GB single partition like a USB Flash. :laugh:
I thought may be after shorting the capacitor, I will get back partitions but this time I got QDLoader 9008 mode. Now whenever I connect phone to PC with or without battery then it is detected in Qualcomm QDloader 9008 mode.
I tried Boarddiag v3.99c but unfortunately this tool doesn't extract .kdz file of my LG G2 F320S korean variant. I tried to extract .tot file of LG G2 D802 (intl variant) and it completed successfully, so the problem is in .kdz file of my cellphone(probably not supported by this tool).
I can extract this .kdz using LGFirmware extract tool but unfortunately it doesn't create "partition.txt" file which is required in boarddiag to flash partitions. I used partition.txt file of LG G2 D802 but it gives error : No DLoad mode when trying to reflash programmer".
Any help would be appreciated.

Boarddiag full and working version helped
I have tried a lot of times to flash the partitions using boarddiag but it failed. It was the problem of the software because almost all versions had missing files. At last, I have found a working version of boarddiag which detects my phone and I am able to flash boot partitions to it. Although all 3 tests completed successfully (AP, EMMC, SDRAM) but still I am stucked, even after flashing all the boot images, I am still stuck in QDLoader 9008 mode and whenever I connect it to PC (with or without battery), it is detected in QDLoader 9008 mode.
Here is the link to the full working version of Boarddiag 3.99 for LG G2:

(mega is blocked in many countries so you may have to use proxy/vpn to open this link)

Here is the result of all 3 tests. Please tell me whats the problem. SDRAM result is FAIL but why so?

Now I am able to enter "Download Mode" but unable to flash stock or any other firmware. I tried flashing with 2 softwares:
1. LG UP-G2-G3....This software gives error at 6% (at LAF read) as shown in picture below :

2. LG Flash tool 2014.... This software gives error at 4% by saying "Unable to Establish Connection" though connection is fine because phone is detected in Device Manager and in Download Mode "It shows signs that communication is successful but it wont flash.

Did you try the TOT flash method already? It worked best for me, when I restored my phone from scratch 2 days ago.

Dear I have tried two methods. I tried LGUP and LG Flash Tools 2014. But both fails. Unfortunately, no TOT file is available for my LG G2 because its Korean variant (F320S) and it has only .kdz firmwares available.

QDLoader 9008 mode
Now, my phone is not entering download mode. It is displayed as QDLoader 9008 mode when connected to PC. Check the screenshot here : https://ibb.co/yk3VSbS
I have the working version of boarddiag but sometimes it passes all 3 tests and sometimes fails EMMC test ad sometimes SDRAM test is not completed successfully.
