Greetings. I have a lg v20 us996 and the problem is this. After flashing it with lgup UPPERCUT_1.0.0.0, now the phone reboots into fastboot mode. I have given factory reset and I have flashed another filmware of the same model and still the same. I turn it off by removing the battery and when I connect it to the computer or the home charger, it lights up in fastboot mode. any solution. Thank you
When that happened to me I had to send it in for factory warranty repair. Their diagnosis was faulty ram. Phone came back unrooted and I really don't know if I should try to reinstall TWRP and root. I get the message that the phone cannot be checked... when I boot up, which leads me to believe the bootloader is still unlocked. I miss TWRP and root REAL BAD so will probably give it a try but am not brimming with confidence.

Greetings. In my case it was not root and no installation of twrp. It was after flashing of the filmware that I left in fastboot mode. Now does not boot and gets stuck in fastboot mode
This happened to me when trying to update my old LG K10 through LG Bridge and it failed. After it installed the update properly, it booted normally. I think it's a flag that LGUP or UPPERCUT fails to reset, so the phone thinks it's still waiting to install the update through LG Bridge's Update Error Recovery.
might be of use here
i had a h910 flashed over to us996 that was stuck in fastboot. i had tried everything from flashing all the us996 firmwares to frp reset and came up with nothing. i then flashed H91510c_00_VTR_CA_OP_1007.kdz it not only successfully flashed but got me out of fastboot mode. i am now reflashing the us996 10f and will re root and twrp .. hope this helps someone out.

You just saved my xmas!
I think the reason it works is because the partition layout is redone because the partition layout is different. So it has to be re-written which is what needed to be done to fix the issue. The Korean F800 version has a different partition layout as well so that prolly would work too, which I actually had before I downloaded the H915.
This also fixed the issue I was having in the first place that made me chip erase which didn't work. But now I know what's going on, writing a fresh partition table can solve many issues which doesn't happen when crossflashing variants that have the same partition layout.

Hello,
I own a Huawei P8 L09, bootloader unlocked, rooted and with TWRP recovery.
I tried this morning to flash a new rom using TWRP recovery.
Problem is that I do believe I wiped to many partitions and I ended up with a bootloop.
I could at first access 3 times the emui erecovery (btw, Wifi recovery failed) but not anymore (is it related to the battery level ? I don't know how much I still have)
Following a lot of threads here and on some other forums (I've been searching now for approx. 7 hours...) :
I downloaded a update stock ROM (B170 something), I extracted Boot, System, Recovery and Cust
I entered bootloader mode (it's the only mode I can go to; recovery No, Download mode neither)
and on my computer I typed in the cmd "fastboot flash recovery recovery.img" same with system, cust and boot.
All of them said "Okay" but the bootloop is still there and I can't acess any other mode or shut the device off.
Also, my bootloader indicate that i'm "unlocked" but when I try to do something as :
"fastboot erase cache" it says "remote: not allowed" or something like that.
I tried the SD card flash method but I can't even acess the 3-button mode (doesn't work - bootloop again).
Finally, I've got 2 questions :
1) Is there a solution ? Is there/was there anybody in the same situation ?
2) Does the battery level influence wether I may or not enter any mode ? like b.e. under 30% I can't access recovery or something like that ?
Thanks in advance for your help and sorry for my bad english.
Greetings from Belgium !

Hi!
I have the same situation as you do, All i know is that you can access the eRecovery only if you're plugged in.
But it's completely useless. Have you found any solutions yet?
Edit:
i struggled and i'm still struggling but i figured out that I need the recovery and boot img of the version i was on previously. In my case that is B350.
The main mirror is down but i managed to find another one: https://mega.nz/#!NAcgQY7Y!I4eRfkaq62J31csv_wZ8_nTzmUbWPX71JUicDysjus8
after flashing them i was able to partially flash (using vol+-&pwr) B170 (it only went up to 90% with my USB attached, fails without USB)
At my surprise it booted B170 even if it didn't complete, however right now it keeps rebooting every minute. I'll update if i manage to fix this
I have the same problem as you both. To flash boot.img and other files by fastboot we need to unlock bootloader. To unlock bootloader we need to have Imei, Product Id and SN, but I can't read it because phone won't turn on.
Anyone know how to get this info?
you can read these info from the packaging box!
I managed to fix my issues (i believe) by continuously flashing and flashing versions. I never really managed to fully OTA update to 100% due to some "CUST error" but from B350 i managed to "update" to B170, then to B200, then to B321a.
Now i just installed TWRP and rooted it and on the process of installing xposed (if possible).
I wasted a good 6-7 hours on everything already
Well now I actually sent my phone in repair, given that it still was under warranty.
If they return it unrepeared, i will try it your way, Nikooo777. Thanks.

Hello,
I'll try to detail as much as I can to explain how i ended up Bootlooping :
I tried today to root my LG H870. (imported from Germany, according to the seller).
I followed the tutorial on xda to unlock the Bootloader on the device.
After flashing it, it launched Android the 1st time without difficulties.
I rebooted into TWRP, flashed supersu, then rebooted into Android. Problems started there, the system told me my partition was encrypted, and asked if i wanted to reinitialize it. After doing so, it's been stuck, bootlooping to TWRP, the internal partition empty.
I followed numerous tutorial on how to flash a stock ROM through TWRP, Fastboot, ADB Sideload, without any success.
With TWRP, it was always ending up saying the flash wasdone, without writing a single file in the partition.
I also tried installing stock ROM with LGUP, but once again, didn't seem to work. While in download mode, it was either telling me the phone was an unknown model, on port COM3, or that there was no handset connected.
I then followed another guide, using LG Firmware Extract and LG Flash Tool. It didn't work as expected, but, I don't really know how, it made LGUP seeing my phone correctly. I was then able to flash a stock ROM (H87010f). No error during the process.
After the LG Logo, i get now a blue screen, saying for some seconds "Encryption Progress", and after that "Factory Reset Status", with a big red "2", and it gets stucks there.
Once again, if I get into download mode and into LGUP, i get now the "no handset connected" message.
Is someone on here able to help me?
If more infos are needed, tell me, i'll try to answer!
Thank you all!
Alright so this has happened
I was all a happy guy on H915_10e rooted rom on my H910PR when I decided to my destruction, flash Lineage 15.1 with second screen support as well as trying out gamma kernel for second screen. Turned out xda's dl server crapped on me by refusing to letting me download the SS gamma kernel for LOS 15.1
I ended up flashing x86cpu's LOS15.1 and then after a day I only observed phone lasting me 6-8 hrs due to the greyed out NFC and no option to get the problem sorted out (seemingly I am the only one having this issue).
So all I had to do was flash stock kdz again and start from zero to dirtysanta H915 rom
I have sold my PC and thus am left with two laptops (both have USB 2.0 as well as USB 3.0 ports).
I first installed LG drivers WHQL v4.2.0
Then I installed LG UP v1.14.3
Then I extracted the patched LGUP in correct folder (double checked)
I put my phone to download mode and connected > it gets recognized in device manager.
Now when I try to run LGUP, it says unknown in device model and shows me H915_10e (surprisingly enough its running on lineage 15.1 H910 with gamma kernel). It doens't let me proceed further. Even after using uppercut
I tried the guide to unbrick in LG G5 forum which basically follows LG Flash tool route which failed for me too.
After that I looked if I could get to TWRP and yes I could, as well as the engineering boot is still there (fastboot commands work).
Now that I do have full flashable image of H910_10r from brian's guide to root, when I try to reboot after flashing TWRP gives me an error that no OS is installed and I get stuck at LG Logo (not even the warning screen).
I tried flashing Super V20 rom as well and ended up in the same den. I havent tried to flash LOS back but that's of no use to me (battery nightmares).
Whats the valid route here to get back to my H915 or H910PR rom ? LGUP isn't working for me despite being patched
-Thanks
Put that h910_10r zip along with Magisk onto an SD card. In TWRP, wipe everything / format data, then put the SD card into the phone, and flash that zip. Once flashed, flash Magisk.
Before you reboot, make sure that data and system are mounted, unmount them (uncheck them), and then mount them again.

Did so, before rebooting TWRP asked me that there is no OS installed.
Surprisingly after every flash process I checked in download mode if there is any sign of identification.
I ended up flashing full stock H910 10q through TWRP, still the phone said there is no OS installed. The same error popped up when I flashed super v20 full stock H910 too.....
welp, now I'm with locked bootloader with Firmware update screen showing me "633A B50" in the information and stuck at 0%
LGUP still identifies as unknown device. Looks like I've ended up in the same basket as some of the fellows who got stuck with disfunctional download mode. I'll try tomorrow if I get to buy another Type-C cable although phone identifies correctly even in LG Flash tool (the identifier worked as H915 before, then changed to H910PR when I tried the H910PR kdz on provision of LGUPc.dll from extracting the kdzs.
I can't do anything except charge phone and if I try to power it on, its stuck on LG Logo (no warning screen whatsoever and there is no going back to TWRP as of now.
I even tried kdzwriter and it just remaining blank on the kdzwriter commands despite I could see kdzwriter in sbin directory and manually setting permissions to 755 through twrp file manager, still it did nothing.
Also, the bloody funny thing is, LGUP still recognizes as H91510e while LG Flash Tool recognizes phone as H91010q as well as shows LG-H910 on the phone firmware update status log. Something from full stock H91010q didn't erase that info as well
Wait, how do you know you still had the engineering bootloader other than the fact that you could boot to TWRP?
If you had no warning screen, then you probably didn't.
You may have bricked your phone, but we may be able to learn something.
Edit: FYI .. you still may not have bricked your phone yet if you still have download mode.
EDIT2: If you want to save your phone, don't do anything else for now.... read the laf development thread, not the lafsploit thread....

When I had engg bootloader (which facilitated all fastboot commands we need to flash modem recovery blahblah etc) and TWRP, the phone sat on LG Logo all the time if I did a normal bootup or reboot through recovery.
The warning screen only poppped when I used the enter recovery combo.
Also H910_10m has something different than H910_10r.
The warning screen on 10r is perfectly crisp and clear but the warning screen on H910_10m firmware is distorted all accross the screen with parts of it horizontally distributed all over and wrapped around.
Rigth now:
I have working download mode and only way the phone talks a little bit (mamma papa of a baby maybe) is through LG Flash tool when I give the LGUP.dll and a kdz to flash to it. It says its an LG-H910 on download mode status screen and says two lines about H91010r and the next line as the line of the firmware I'm trying to flash, here in my case those are H91510e and H910PR10j.
I can even go to factory reset screen and the nice circle spins saying to me erasing but it reboots back at LG Logo
I have full dump of my H910PR but that's useless if LGUP doesn't recognize my phone.
TLDR as of Now: I'm going to install Windwos 7 on my older Lenovo x230 Laptop and start from scratch. I believe there is a bad driver footprint left somewhere in this windows 10 and I hate windows 10's communication trouble with third party devices.
Will keep you updated via this thread. I hope I do not annoy you too much with my post backs
Bump! No chance. Stuck in same situation but now I have only access to download mode or factory reset (since I'm on stock H910 10q firmware). LGUP says unknown with H91510e while LG flash tool says it's H91010q. Can't flash sh**.... I've ordered a replacement H910 motherboard and it's gonna arrive in 15 days give or take. Will see if I can swap connection Midway in LGUP and flash this one to stock H910PR
Hey everyone!
While trying to update LineageOS on my G6 I somewhat messed up and now am out of ideas. I tried to install an OTA update, which sent me into a TWRP-bootloop. I tried to fix this by using the dd-commands described here before seeing the next post, which advised against it and recommended a different one. Unfortunately too late. I did back up both partitions on my external SD card, though.
Since then the phone is in a boot loop continuously displaying this screen (the author of this thread seemed to have a similar problem - but it wasn't resolved there). I can get into fastboot and download mode with the volume buttons. Getting into the reset-menu and trying to open TWRP from there doesn't work, it just goes back to boot-looping.
Do you have any ideas how to recover from this situation? Ideally without a factory reset... although I have most of my data backed up the storage is encrypted and It would be awesome to recover into the old system. I still have a little hope left that I haven't messed up quite that bad. :/
Thank you!
your data is lost because you can not do anything anymore
make full wipe with fastboot because LGUP currently update supports
fastboot format userdata
fastboot format cache
fastboot format system
go into download mode and flash stock with uppercut and LGUP do you get errors check drivers or take another stock rom. !!! you can not flash a US Stock rom to a EU Model (this was an example !) !!! watching exact your model [H870/H872/US997] and rom
For me it has worked successfully H870 with 20c open EU
I believe we all know here how hard flashing Nokia 6 phones are... they are unbelievably a PITA.
I have a TA-1025 Nokia 6, 7.1.1 Nougat. I have been trying to fix it for 3 days now with no success. Originally tried to reflash stock boot image at first with little success so I could flash Magisk. Ended up wiping out entire System partition and trying to reflash, getting nowhere. I then flashed a B02_Homebrew.zip which ended up with stock recovery and no root at all (and no ability to flash magisk despite having unlocked bootloader. great.) Downgraded bootloader again and am now stuck and unsure how to proceed.
Note I CANNOT get QFil to work without EDL mode, which requires me to tear my phone apart.
Any suggestions? Does anyone have any certified knowledge of how to fix and reflash stock Nokia 6? I don't want to take it to a dealer because they will update it and make it unrootable (and probably won't be able to even touch it since bootloader is unlocked.)
ATM, all I can boot to is TWRP recovery or Download Mode.
Help?

You can use TA-1021.
If you want Nougat Ver. then use Nokia OST.

First flash stock recovery, then boot into stock recovery and flash latest OTA
Link for latest OTA got from Telegram (TA-1025 ) : https://android.googleapis.com/packages/ota-api/package/5d91fc596557fecf1ba49b9321b446c64e3acd06.zip
Note :Your bootloader will be remained unlocked. don't worry

It shows up as a QualComm COMM port device. But before you get your hopes up, every time I have tried to flash it, it says "Failed to switch to EDL mode" :-/.
