I have an LG V20 F800L, it with oreo and rooted
When I play mobile legend sometimes it hangs then shows a green screen and it shows message watchdog bite ...., i forgot the detail. It keeps happening sometimes and I just let it. until it auto off because the battery drained then when it charged it, it showed purple screen and showed a secure watchdog bite!
I tried to unbrick it use uppercut, lgup but not success because it cant detect my phone model
i tried to do test point method but it not success with some error (looks like the file for F800L is not available for test point process)
when i try to enter download mode, it always ended up with purple screen and message "secure watchdog bite!"
then i found a thread with fastboot method by flash partition 1 by 1 with extracted .dz file, i did it and it make the purple screen gone but i cant enter fastboot & when i enter download mode, it keep restarting
anybody have advice / give guide to make my LG V20 back to life?
I had a weird issue come up. Something fragged out after I installed lineage 18. I ended up downloading multiple different versions of the kdz file. And tried to kdz every single one of them using uppercut. Finally the 20c kdz for the vs995 worked. However there where are some Trace elements from the old ROM. Magisk and a few other apps are on there. However the phone is no longer rooted. It's like the stock software from the kdz what those apps plus my fingerprint and lock pattern worked right after it booted up ( even with no setup process). Not sure how that happened but the other kdz variants flashed completely but did not let the phone booth back in to the operating system.
Long story short. Try different kdz from different updates. Hopefully that helps you out.

I have LG L4 (E440), and recently it got in Boot Loop (after I installed some programs it just turned off, and whenever i try to turn it on, it just shows LG Logo, then LG Animation and starts just repeating animation). At first I was quite confused because I didn't know how to enter download mode (you have to hold both + and -). I thought that was the only problem i was to encounter, but i was wrong.
- I first downloaded LG Support Tool, updated drivers (a lots of them), and went into update mode. Everything seemed OK, but at third step (Software Upgrade), program would stop at 5% and it would give me message like "Disconnect, Remove Battery, Connect, Retry". I tried all of that multiple times, and it stopped at 5% every single time.
- Then i decided to download LG Flash Tool 2014. I took 5 Firmwares (V10E, V10F, V10B, V10C, V10D) and each one of them failed at 5% (one of them failed on 3%). I tried both 3GQCT and CDMA, and all phone modes (EMERGENCY, DIAG, CS_EMERGENCY). None of those worked.
Each time Update stopped at 5% it was because of -
drivers\mstrgen.sys file search fail.
(log is in attachment)
Looks like this driver is missing, or being corrupted. I found out that it comes with MCCI Firmware Update Driver for MTK, but the only one i could find on Internet is giving me "Install Fail" each time i run installation.
I had not as nearly as much problems unbricking LG P970, and i need this phone unbricked fast but i'm all out of solutions Any help would be appreciated!
Hello
I am new to working on these phones so I apologize in advance if I don't properly state any processes or terms correctly.
I have a stock non modded Verizon LGG3 VS985 that experienced problems with WiFi and Bluetooth not working and significant battery drain. This happened right after a recent update to marshmallow. I tried cache clearing, safe mode, hard reset and nothing solved the problem. I decided I wanted to take the phone back to factory condition. I started with the LG flash tool that uses the .tot and a .dll. I ran the flash and when the program got to approx. 80%(at checking mini os phase of the flash) the phone began to reboot and only got as far as the LG logo and after about 2 min of the phone trying to reboot the flash program said fail, usb connect or something like that. At this point the phone will only start and go into a loop that includes the vibrate and the LG logo. and that will cycle until I believe the battery would die if allowed. I then found a link here at XDA (https://forum.xda-developers.com/verizon-lg-g3/general/guide-flash-to-stock-10b-kdz-method-t2928140) that uses the KDZ method, was well written and easy to follow. I ran it on the phone and it was going great. The flash program got to 88% and the phone went into the boot loop with the vib and LG logo . The flash program continued to run until it was complete while the phone was in the boot loop and it got to 100% and said that the software installed. I powered down the phone via battery removal and now when it tries to boot it vibes, shows the lg log and then the green android symbol shows for about 2 seconds and then it does it all over again. I have tried a hard reset and nothing changes. I appreciate any ideas any of you may have on what I can try to get this resolved. Thank you.

I have been given an S7 SM-930FD [Dual Sim] that was supposed to be bricked. It wouldn't boot into anything but I have successfully got it into download mode and been able to successfully flash a stock ROM downloaded from Sammobile [several times] with no errors. Each time I have used the full set of AP,CP,CSC files and the previous owner is not sure what ROM it was on or what he tried to install. I have tried different versions of the firmware for this model for various android versions and regions simply to try and get it to boot, but without success. I have tried HOME CSC and CSC files too.
But each time it starts to install the update / reboot it hangs. Either when it installing the update on the blue screen with the robot and its "erasing" - small rotating symbol just stops and nothing happens OR it loads to the GALAXY S7 normal boot screen then hangs.
When it hangs it will only respond to one key combination Power + Vol Down. It then "switched off" and will not reboot in any mode. When I say "switched off" I mean the screen goes black. However if I then connect the charger, it won't show the charging symbol UNLESS I leave it for a few hours and the battery goes flat. It will then charge and I can boot into download / recovery mode but normal boot starts installing the update and it will hang all over again. On one occasion it hung with and black screen and blue flashing light but again no key combinations worked and I had to wait for the battery to drain.
Also tried Smart Switch Emergency Recovery. Even with the drivers freshly installed it does not recognise the phone, it does accept the model number during initialisation, but once the S/N is entered it comes back and says it can't find the model, S/N or IMEI in the database!
I have researched the web for hours and watched every relevant youtube video and tried their suggested key combinations etc and they just don't work.
So I'm hoping someone can help me resolve this frustrating situation, not least because of the delays between attempts!
Presumably as I can consistently get it into download mode there is a solution out there somewhere???????
What am I doing wrong? Should I be looking at a custom ROM or trying something else?
All help appreciated.
HELLO MEMBERS
I was working on a device D850 stuck on factory reset status 2 blue screen and used TOT method, after a lot of struggle and head scratch i finally got the device onto flashtool, but the problem i am facing now is that despite whatever i do the phone is constatnly in a boot loop for a brief moment it will show a factory reset sign but then the tail chasing starts again. this also happened during TOT
i am using
LGD850_20140613_LGFLASHv160.dll
and
LGD850AT-01-V10d-310-410-JUN-19-2014+0.tot file
but its t working as mentioned i am following every step carefully. and due to my sluggish internet I had struggled with download process
a help will be much appreciated , it always fail at 94% and start the loop process
Ps: i am also unable to access stock recovery
Had it for 3 years now, it first looped in October 2017, broke all the sensors but has otherwise been working fine since. I also rooted it about 7 months ago in case that makes any difference with recovery. During both of these loops I have been unable to reliably get into recovery/download mode. I left it alone for an hour earlier today and came back to find that it was somehow in Odin/download mode with the text in the top left but still on the boot screen. So I plugged it into my computer, it was detected and then I flashed it with the correct G930T firmware and home csc. Got the success message in Odin and it seemed to be working but it was just stuck on the boot screen now. So now I've just been trying to flash it again with the other csc but it has been failing for a lot of different reasons and I don't know what any of them mean. I did manage to get it to power on a lot more reliably and into download mode, but still having problems. The biggest problem is when I get to either the download screen or warning screen, the screen suddenly gets all glitchy and I can't do anything. Whenever that happens it also shuts off after 10 seconds. This also happened on the Smart Switch emergency recovery screen when I cancelled a stalled flash and then tried to flash it again from that screen. I've also gotten errors when trying to flash from the download/boot screen. The ones I can remember are "unsupport dev_type", "secure check fail : tz eMMC write fail : tz" and "secure check fail : hyp eMMC write fail : hyp". I can't even find anything else on these errors and have no idea what they mean. I also have no idea how it is getting into Odin mode on the boot screen but so far that is the only way I have been able to do anything since I can't get into download mode the proper way. Lastly I tried to check in Smart Switch to recover it but it says the device is unsupported and there is nothing in emergency recovery.

When you flash with Odin tick "'re partition" in Odin options.
When "pass" appears disconnect phone from pc. Force reboot by holding home+volume down+power.
As soon as screen goes black press volume up while keeping home and power pressed. When recovery menu appears choose wipe / factory reset. Then reboot.
What is obviously very important is you are flashing the correct firmware for the device in the first place.
