I was attempting to unlock my boot loader and flash a custom ROM, I was following a guide on YouTube specifically for this phone, and he was using US99610 firmware instead of Verizon firmware (to prevent uncontrolled vibration during 1st boot) I messed up the process and couldn't get back to TWRP, so I used his patched LGup tool to attempt to flash stock firmware back, because I could no longer use my phone's screen without connecting to HDMI and using a mouse and keyboard. I flashed it back to stock and everything seemed normal, until it didn't boot at all. I then tried to reflash the US996 firmware and LGup stopped at 4% with an error: SPC code does not match, please try again. Any ideas how I can unbrick it? If I connect it in download mode the tool still sees my phone fine, with the US99610 firmware on it. I can post pictures and a link to the YouTube video for further clarification. I've tried using patched LGup and partition dl to flash back, that's what throws the SPC code error. Any help would be appreciated

Hey everyone I'm quite new to android, and I'm currently stuck in Download Mode after trying and failing to install Twrp
I was previously Rooted, tried to install Twrp via Autorec, however when I ran the app it soft-bricked my phone and put me into Fastboot mode.
I followed http://forum.xda-developers.com/show....php?t=2476972 method, and got back to Download Mode.
I am currently in the middle of returning to stock through http://forum.xda-developers.com/show....php?t=2432476 using the .TOT method.
I'm fairly close to repairing it but my only issue is that I cannot get my computer to recognize my phone. Neither in Device management nor adb devices anymore.
Therefore I cannot change the port to COM 41 to flash the .TOT file.
I constantly tried installing drivers for the phone both 3.10 and 3.08 but still no recognition can anybody help?
Some more info about the phone:
it's the D801 variant but its on Wind (Canada) not T-mobile
it was previously Rooted
it did not have any recovery software installed
no roms had been flashed previously.

Try to restore your phone using the official LGMobile Support Tool. Just switch on normally the phone, plug it to your PC and wait for your kdz to be downloaded. Once it done, it should install the kdz by itself. Then factory reset your phone (if needed) as it should ask you some pin/password.
Hope it'll help you as it did for me!
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!
Urgent help needed as I'm leaving the country at the end of the week o any help is appreciated!
Just successfully rooted my device:
Black, Unlocked, PRA-LX1, UK, Dual SIM
After doing so successfully, I attempted to flash LineageOS from the following link:
https://forum.xda-developers.com/p8lite/p8-lite-2017-development/rom-lineageos-15-1-hi6250-devices-t3811583
Although when I completed Step 6 on the Installation guide and rebooted the phone, I started seeing the message:
------------------
ERROR MODE
Attention!
Please update system again
(Green Android picture)
Error!
Func NO : 11 (recovery image)
Error NO : 2 (load failed!)
------------------
Despite this, I didn't receive a box with my phone due to being second hand, and I didn't see the model number on the receipt as it was from a reselling store. I didn't remember to note down the specific model number
It'd be extremely helpful if someone could possibly help just from the device description above as I'm not sure if it's safe for me to just attempt to flash every stock rom for every other LX1 device out there.
---------------------------------------------------------------
Update:
To restore this, I connected via fastboot with a working USB & flashed an original stock recovery in the video found here
(Just in case their download link ever goes down, I have uploaded the same copy to my MEGA, found here)
The recovery installed fine when using the command
fastboot flash recovery oeminfo.img

Whenever trying to flash any other recovery such as twrp before this fastboot stuck on a loading icon.
The stock recovery seems to be downloading the original firmware, too.
PRA-LX1C432B202 is presumably the model.
Both the bootloader and FRA were unlocked when everything else was inaccessible.
Looks like the custom ROM's recovery that you've flashed is not compatible with PRA-LX1. Try to flash stock recovery. If not working, then flash stock firmware.
Thanks @Botar230!
I didn't see your comment until just now after deciding to edit this post since I've gotten a step closer to restoring my device.
Your solution was the method I used although I didn't know my phone model, so I found a random solution which just worked for my device, and the eRecovery seems to be downloading the stock firmware anyways. Thanks again
Before flashing this lineage os you should update to EMUI8 to get treble support, i suppose you was running EMUI5, hence the error mode.
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
Okay, Let me explain exactly what I did here... I first flashed Twrp using SP flash tool which worked without too much problem. Then I attempted to install the latest super su zip which told me the boot.img was already patched and it could not find a ramdisk... So I moved on and flashed the latest Magisk zip which flashed no problem. Rebooted the device and it came up with a red boot state telling me it would boot in 5 sec. It did not boot at all. Turned off the tablet and rebooted into twrp again. I then flashed the OTA update system.img, boot.img, and re-flashed twrp from twrp itself instead of the SP flash tool. It booted into twrp no problem, however now it said it could not mount the system partition. I did a full data wipe, factory reset, rebooted into twrp again. Same issue. So I attempted to re-flash the firmware with SP flash tool. Did not notice i had it set to format and download and not only download. It said formatting for maybe 2 sec and gave me an error. Now the device will not turn on at all... no screen whatsoever, no recovery, etc... I have had no luck getting the asus flash tool to even recognize a com port however SP flash tool seems to be able to flash the device no problem. I extracted the .raw firmware file I have for the latest firmware, modified the scatter file to allow flashing all partitions, and I did a full firmware flash of the device using SP flash tool. However it still does not turn on... it does nothing... So I'm assuming that I accidentally formatted over the bootloader... And I cannot find a bootloader flash file for this device anywhere... So I'm stuck with an Asus ZenBrick... Does anyone know a way to fix this issue? When I plug the device into my computer and open device manager it switches between the preloader and mtk serial port very quickly not staying on either one very long. I'm assuming this is why I cant get the asus flash tool to work and SP flash tool works off just the initial preloader. I just bought this tablet from someone and managed to hard brick it in less than a days time... Any help at all with a way to revive this device will be greatly appreciated. Thank You in advance to anyone who tries to help me fix my mess up.
