Hi guys !
I'm currently trying to unbrick my F600L in bootloop since I tried to downgrade from 20q update.
I founded out later that the V10 has anti rollback feature but it was too late.
Now i'm looking for a kdz or anything flashable to restore my system...
By the way I always get a " invalid command response" error with LGUP while flashing "system" do someone know how to fix it ?
I tried to reset it with LG Bridge but il always fails because the detected software version is the 20q which is the latest... Is there a way to force the restore or update with LG Bridge ?
I tried recovery error fix too but it doesn't find any error...
software update (korean version) stuck at 21%
I have the same problem here. I tried to get back to LL Firmware F600L20n while my phone was on Firmware F600L20q. I used LGUP but it always got stuck at 21% percent on PC and 13 % on LG V10 F600L. And it also showed error codes 0x2000 invallid command. Please help.

How did you unlock the bootloader?
Related
I was recently given an LG Optimus L9 P769BK and decided to try and unlock the bootloader and root it. Most of the guides (such as: http://forum.xda-developers.com/showthread.php?t=2584997) suggest flashing to V10G_00 first before flashing to the EU V20B_00. I was able to flash to V10G (from V20H that was already on the phone using "LG Flash Tool 2014") but now, no matter what tool I use, I am unable to get ANY ROM to flash to the phone.
Methods/Tools used and the results:
1)http://forum.xda-developers.com/showthread.php?t=2085344
1a)Result: The software that is launched in Step 10 crashes before doing any updating
2)http://forum.xda-developers.com/optimus-l9/general/p765-unbrick-using-lg-flash-tool-2014-t2950433
2a) Using CDMA + Diag or Emergency: Goes to 10% of SW Update then fails with an error saying to remove the battery and try again. Doing this does not resolve the problem
2b) Using 3GQCT + Diag or Emergency: Can not connect to phone. Reseating the connection and power cycling the phone does not resolve this.
3) http://forum.xda-developers.com/showthread.php?t=2748384
3a)Using the LGP769_20121004_LGFLASHv1350.dll and a bin from V20B_00 it freezes around 570 seconds with a write error. The phone no longer boots outside of SW Update Mode.
The phone will now only boot into SW Update mode.
System:
OS: Windows 8.1 64bit
Drivers: LGUnitedMobileDriver_S52MAN314AP22_ML_WHQL_Ver_3.14.1
Any thoughts on what to do next?
UPDATE: The LG Flash Tool mentioned in 3) no longer sees the phone. After following the steps mentioned in the guide again
UPDATE2: Reinstalled the drivers. Method 1) still crashes, 2) same results, 3) still not "seeing" the phone when connected.
UPDATE3: (using Win 7 machine). Method 2) gives an odd "Can not connect to server error" when tried. Method 3) gives a write error on "Failed to Write OMAP" (ill get the exact line in a minute)
UPDATE4: Ignoring the error (aka NOT clicking the box) from Method 2) allowed the phone to flash with no problem
Only the very first v10a had an unlockable bootloader. And the first couple of v20ies or all of them. I unlocked and rooted with v20c, later versions could have locked Bls.
My phone actually has an encrypted bootloader so no ROM will work
I have no soldering skills so I ordered a 910k cable and will do the unlock with it.
Current situation:
I have a LG G5 H850 VDF that had been unlocked official BL, and also flashed the TWRP Rec and rooted.
when I power up my H850, there is a tip on the screen , which contain a exclamation mark with yellow or red background.
I flash the kdz file in download mode via LG UP, it always stay at 9% each time, and shows a error:
Error: Error Code = 0x81000304, CBasicFlash::_func_LoadGptF...-Error Code:8224

(drivers and dlls have been installed. )

How to unlock bootloader?
Do i have to root my phone?
please, see this post, let me know if helped
http://www.reviversoft.com/answers/...lem-with-the-firmware-update-and-verification
Hi all, I've been trying to flash my LG G7 LM-G710N to latest Pie firmware using the needed kdz file from LG, since my G7 won't receive OTA updates and latest security patch is Sept 1 2018 -.-
I have done every step in the how to on lg's site, but for some reason LG UP will stop at 4% everytime, with a dialogue box poping up that says:
Error: _checkCrossDL Fail.
Phone = LM-G710, KDZ =
Does anyone know how to resolve this?
Greetings all, I have come to ask for advice on how to debrick my lg v60 version V600TM20n. First, how I ended up in this situation.
To begin, I followed this guide to unlock bootloader and root my phone then I followed this guide in an attempt to install a custom rom however, i did not get too far.
I tried to remove vbmeta verity as per the requirements of the form and in doing so input this line into my bootloader fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img with the file provided by this form I think this is where the issue I have is comming from but moving on.
I then attempted to download lineage os following the guide but it did not work and I was fed up by this point to I began the process of reverting everything I did. I downloaded SuperSu to deroot my device. After derooting my device I went to the bootloader and typed in fastboot oem lock, locking my device and dooming me.
In my attempts to escape from the hell I am currently in I downloaded LGUP v1.16.03 and v1.14 (I tried them both deleting the previous one before installing the new one) yet each time I was stuck with the this error code Error Code = 0x2000, Invalid command response when the progress bar reach 9%.
The dll i used is version 0.0.3.23 and the one provided by LGUP v.1.16.03, and the firmware I attempted to download was V600TM20n_02_TMO_US_OP_0111.kdz on LGUP it says V600TM20n oh and also I did try UPPERCUT, no resuts
Currently on my phone's download mode screen at the bottom in red it says Modified / E / L / RO / id : 3(NA2_US) I have also tried LGUP Cmd but same results
I have tried LG bridge but it says connecting and then no device found :/
I wish i could say i tried lg flash tool but i have no idea on how to use it
Possibly another big mistake (idk what im doin) I used the QFIL and restore the abl_a and abl_b to their original versions after locking the bootloader.
Please tell me if there is anything else I can do or if I now own a $300 brick. If I do have a $300 brick is there any value I can get from it to fund my walmart flip phone that I will have to buy?
