I have an H872 on Havoc 4.4. I have upgraded to a Pixel and will be giving the H872 to my father-in-law. He will only be using it for phone calls - very unlikely he will text, and definitely won't use data. It will also be his first smart phone. Since the H872 is rooted, when it boots up it gives the warning display that the phone may be "Corrupted". I don't want to have to explain all that "root" stuff to him, etc... I want the phone as basic and simple as can be, hence , I want to reflash the stock firmware.
I am having troubles though. Booting the phone into download mode and starting LGUP fails to recognize the phone. I've tried with Uppercut as well and it says I'm missing a file in Apps/Roaming, etc...
Not sure the problem because I have reflashed stock many times with LGUP. Could it be that Havoc has changed the "identity" of the phone, or that it's on Android 11?
Any help to get this back to stock is much appreciated!
Got it figured out. Flashed back to an older TWRP (was on Orange Fox), flashed an old stock Oreo ROM, and then was able to flash kdz with LGUP.

Hello guys, I have a D802 phone and I was on Ressurection Remix 5.0 but since the official lollipop update was made avalaible, I wanted to return to stock and unroot so I could again use my warranty(for some weird reason they couldn't tell last time I took it there that it was rooted). Basically my problem is that every guide for going back to stock has the phone connected to the PC and use the flash tool. Well, I did that but when the mobile support tool opened for the upgrade, it couldn't find my phone. So I found a guide that showed you how to extract and rebuild a kdz file into a .zip. I tried that, used the UK d8023b rom ( A friend of mine who has a d802 as well, though unrooted, got the prompt to update through the pc suite and it updated his phone to d8023b, thats why i used that version), flashed it and I am now stuck in a bootloop. I have full access of recovery and adb but the phone isn't recognised by LG software. Can you please help me use my phone again? Going into download mode didn't work with the flash tool.
hey guys
i just brick my phone (no idea how, flashed android 7 firmware) after flash my phone was working for like 2 hours, then i let himself update a security options. After update my phone went brick
As far i found :
- installed Qualcoom QDLOADER 9008 driver
- found QFIL programmer
i need to have programmer path (something related to JTAG) and build xmp path
Where i can find them? Or is it a other way to resscue my phone?
I feel your pain. My timeline:
- The phone was unlocked but still in Stock Nougat (7.0?). Got that from OTA in Brazil.
- I tried to update to LineageOS 7 via TWRP. After a full wipe (everything, system, data, card, cache etc) I installed the new ROM. Turned on, bootlooped forever.
- Searching around I found out that there was no modem in the Nougat roms and for some reason I needed to flash a Marshmallow modem for my region to make that work (I think there is no Nougat modems around or something).
- I found a LA_DS modem for 6.0, flashed that using TWRP, still bootloop. Tried other roms using TWRP, still bootloop.
- I then downloaded a full stock old 6.0 firmware to go back to stock but the phone wouldn't accept some files ("preflash validation failed").
- Searched around and found out that you can't downgrade a bootloader from Moto.
- Using fastboot, I flashed the files the phone was willing to accept and it finally booted the 6.0 Marshmallow stock rom, but with no networking (radio/modem/baseband/IMEI missing).
- Flashed the 6.0 modem for my region again and everything worked. Connected on WiFi, dual sim cards detected etc.
- I started to install every update the phone showed to try to update it back to latest MM version.
- The three first updates went ok, the fourth turned off the phone to never turn on again.
Looks like there is no way out of this. My phone is pretty old and MotoCare in Brazil will charge a lung and a half for repair.

Pretty similar situation on my part. I downgraded back to 6.0 and when it tried to take the December update I ended up with the same thing as you. I ended up getting a replacement from Moto for under 100 dollars which was worth it rather than trying to find a solution that doesn't exist.
[H918] Successful root/fastboot unlock from 10J -> No roms are flashed successfully
Hi folks, wanted to share my current state of affairs with trying (and failing) to install a new rom on my LG V2O. Here's the order of events
Received brand new sealed-in-box LG V20 from T-Mobile from a third party seller that came in firmware 10J
Followed all directions to successfully perform dirtycow unlock
Installed TWRP (3.0.2-1)
Backed up, but mistakenly deleted the backup after trying to install Megarom in an attempt to do a clean flash
.zip flashed correctly, but hits boot loop upon reaching LG screen (even after waiting 20+ minutes on first boot). T-mobile screen never pops up
Can access TWRP still and ADB commands
Basically now, I've tried looking at as many H918 rom threads as I could but every single rom I try either: never completes flashing OR if it does complete flashing, the device never boots (either bootloop or stuck on the LG screen). I've never seen the device get past the LG screen for any reason. I am desperate for help on this matter as I have royally screwed up trying to provide a nice gift for my partner but was apparently way in over my head with trying to get a fresh rom on this thing.
Can anyone provide assistance as to how I can roll back to a stock rom? I'd be willing to give up root/recovery. All of this was spawned from wanting to be able to unlock the carrier but I have decided I'll just pay for the sim-unlock service if I can get this back to stock. Would be willing to provide some PayPal cash for someone who can help me out with this matter.
Flash to 10j kdz firmware located in the thread with all the firmwares. You`ll need lgup to flash it.

I got LS997 that was not completely unlocked (Sprint support confirms unlock status but phone did not receive unlock command, and i got no sim card and no previous owners name to re-initiate ota-unlocking process)
First thing i did - i used pathed LGUP and dirtysanta rooted my phone.
Suggested 995 kdz rom was vibrating like crazy (as described in dirtysanta guide) but i got root and started experimenting further.
Than i flashed rootable 996 kdz, rooted, had no vibration problem but got static boot issue, ok, installed mk2000 kernel, no static - all good but still not enough.
LOS16 = gsm/lte unlocked but battery was drained in 5 hours with screen turned off and no camera, got back to 996, rooted, super rom, all good but LTE not operating for some reason. Really enjoyed stock functionality (camera, seconds screen) and decided to get back to stock system.
HOWTO: Root LS997 up to ZV7, did it all, started flashing available 'stockish' roms one by one [this, and this], so there goes bad stuff.
At this moment i was still being able to boot into twrp, so i didn't really notice that phone was bricked, those stockish systems was just hanging in LG logo for hours without any progress. ok, found another one stock ls997 rom in dirtysanta root post, flashed it - and nothing, phone still stuck at lg logo.
LGUP flashing routine that was always helping me recover, now if fully completes partition_dl process but results are the same - lg logo for hours without anything happening, except vibrator motor starting to work on power up on Verizon firmware version and no vibro on 996 variant (as it sould):
996 kdz - stuck on logo
996 kdz- stuck on logo
flashing everything i got from lg-firmwares.com:
US99610g_00_1216 - stuck on logo
US99610f_00_1205 - stuck on logo
US99620f_00_1120 android 8.0 - stuck on logo
VS99512A_06_1114_ARB00 - stuck on logo
download couple more variants and still nothing, phone stucking in lg logo
so how badly i bricked it? is there any method of recovering that i am not aware of?
There is an older thread on returning the LS997 back to stock that may help.

Yeah, thanks, been there.
Unfortunately i'm not meeting 2 of 3 prerequisites:
- Your device needs to be able to boot into TWRP and fastboot mode
- You need access to a computer to run ADB commands to the phone
There are no more twrp presents on device because of kdz uploads from LGUP, i was thinking that it was recovery and aboot partitions that was messing up my system.
And there is no bootable system on device to turn on usb debbuging to run ADB commands as only thing i get is boot logo, fastboot are also locked to 995 or 996 (whatever version i've uploaded last from LGUP, and they are not unlockable because LG recognizes original LS997 hardware identification and refuses to give me unlock.img.
As i get it - the only thing that can tinker with my device is something that can get same hardware access as LGUP (laf is still operational or idk, maybe not, but it should be getting everything up and running but that is not the case anymore for some reason)
So you are saying that LGUP can still see the phone but ADB can't. Did you by any chance do a full system dump of the phone on LGUP before the whole DirtySanta procedure in the beginning? I wonder if those files can help getting things back on track. Not sure if they are device-specific, but I did make a dump of my own LS997, so if you think there's something useful there, let me know, and I can upload the files somewhere.

Yes i did full LGUP backup at first system state, but nature of this backups makes them pretty useless in this system state - because they are just images of partitions.
Only software that can write directly to those partition may be able to utilize those backups, there are a lot of post on this forum describing TWRP routine for making update packages based on LGUP backups.
So unfortunately there is only LGUP, but it only can make backups but can not restore them as it uses some special file format (KDZ) that containing some dll's and data files (like glued partition images with special info of where to put what) and i didn't find a way to make my own KDZ files from backup images.
I'm now getting another idea - that this can be a blowed fuse in CPU ARB protection mechanism, if anyone has experienced ARB 1 please confirm that system should be in this state in case of ARB error
Hello XDA. I recently revived my G6 after it sat in my drawer for years and was delighted to see HavocOS on Oreo still running on it. I popped in my T-Mobile SIM and voila, service. My only issue was horrible data speeds. I tried every network settings and apn fix that is relevant to my device but I was still stuck with virtually no 4G data. So, my last resort was to flash back to stock. Now, I dont know if there is a specific method for this device as I forgot how complicated the root exploit was. But I went ahead and downloaded the latest stock .kdz (20g), LGUP and the drivers and proceeded as normal to flash the kdz over. I had SEVERAL issues getting my device model to be recognized and finally grabbed the right LGUP version that worked. I proceeded to flash the kdz when it gave me an error round 31%. I did much troubleshooting research and came up empty, finally decided to try flashing the stock version it was on (20a) to just restore it.
This worked. I thought I was saved until the phone froze on the T-Mobile logo while booting and didnt budge for an hour. Much more googling and I found a thread that looked promising and seemed to help. At first. It flashed the kdz, gave me the error, and when I tried to flash the dz, nothing. I retried LGUP with 20a stock, unknown model. I tried to go back through the whole rooting process again and stick it out with minimal service. The FWUL/lglaf portion of the guide is where I got stuck. My device would not be recognized in FWUL, I couldnt get wifi so plugged in my ethernet. And then I kept getting "USB configuration not set" and "input/output" errors, and I noticed that while booting FWUL, the step "Loading Kernel Modules" fails. So I assumed that FWUL was not loading any modules, including USB's (which explained the errors), so I booted up my own Manjaro install and cloned the same project there. Knowing all my modules work now, I still get the "Input/Output" error.
So now I'm led to believe this phone is hard-bricked. It registers as a port in Window's Device Manager, "LG AndroidUSB SerialNet" or something like that. I tried following the unknown model guide again to no avail. I'm at a loss. Whatever info is needed for debugging I'll provide. I'm dualbooting Win10 and Manjaro so any methods are viable.
Which specific stock KDZ(s) did you try to flash on your phone (full kdz name)? You need to seperate flashing and rooting as two separate tasks because from your post I can't tell if you are able to boot after flashing stock kdz or not. First, if your phone is not booting, you gotta recover from that and flash a stock kdz.
Also, try using the Dev patched LG UP from this post (thank the dev while you are there): https://forum.xda-developers.com/lg...ssflashing-t3780969/post76510671#post76510671
Try the 'Partition DL' option when you flash and select all partitions in the next window.
Once you are able to boot a stock rom, you can try using a VMWare such as virtual box, install/mount FWUL in a virtual environment and use that to root the phone. I think the process is somewhere here on the runningnak3d's guide or on another post, I will try find a link later.
