Hi guys, I need some help, I received OTA to 6.0 but I can't upgrade because I can't restore the stock recovery on my phone.
I tried using the commands "fastboot erase recovery", "fastboot flash recovery recovery.img", using Rashr, TWRP and many others but the stock recovery doesn't work, in the recovery screen I get the message "No command" and the dead android figure with a red triangle.
I already downloaded the stock firmware and flashed all the files a lot of times and I also have copied my OTA file to external SD card to use it again later.
Someone knows what is happening and how to restore the stock recovery? :crying:
EDIT: I just found a solution in other place, the firware file was corrupted, I downloaded it again and now the stock recovery works.
Moderators, please, close this thread.

Have you tried following the guide on:

Maybe it can help you in the right direction... Just maybe. Hope that it helps
Hi folks. I have the PRA-AL00XC675 (India) variant of the Honor 8 Lite. I recently updated my build to B151 and proceeded to root with Magisk. However, instead of patching a backup of my actual ROM, I extracted BOOT.img from a previous OTA update.app, I couldn't find one for my current build on firmware finder.
After flashing, my bootloader is still unlocked and it boots up, but is now stuck on "Your device is booting now..." screen. I appreciate any inputs to get my phone booting properly again. Does anyone have a back up of the Boot from a PRA-AL00XC675B151 ROM? Or know where I can find one?
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
