Possibly Dead Device? [P8/P9 Lite (2017)][PRA-LX1] - P8lite Q&A, Help & Troubleshooting

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
Click to expand...
Click to collapse
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.

Huwei P8 L09 stuck in bootloop many tips tried, none worked

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.

Asus Zenfone Max (ZC550KL, Z010D), Android M, Unable To Unlock Bootloader

Hi there! I have this question which I'd love to have answered because I've been on this issue for around 2 days straight.
Long story short:
Tried to flash custom recovery using fastboot, didn't work because bootloader locked
Kept on trying the unlocker apps, none of them even installed fully (THIS WAS WHEN I WAS STILL ON LOLLIPOP)
Somehow, at some point, I just randomly rebooted and BOOM THERE WAS TWRP (Sorry, I don't remember how exactly I managed that. As far as I remember, I was only using fastboot and nothing else)
Flashed CM 14.1 unofficial, device gave an error message regarding boot.img (something like "could not load boot.img"
Used stock ROM to flash OTA Android 6.1
Now the Asus unlocker app downloads but on reboot it says "error: unlock fail !!!"
Obviously, fastboot is unable to flash a recovery right now. I tried ignoring the error message and rebooting to recovery to stop the device from loading the stock recovery again but the device still loads the stock recovery.
I'm really tired
P.S: NO, there is no Enable OEM option in my Developer Options menu and YES, I have all the drivers necessary.
Did you get anywhere with this? I have a similar problem except that I couldn't flash Android 6.1 because the vendor had flashed WW 5.0.2 on a CN phone without also updating the CN recovery to WW. So the update failed its consistency check.
I've got TWRP on there now, but can't unlock the bootloader in 5.0.2 - I think this is why TWRP can't flash anything. It can't see the update files, won't switch to external SD, etc. .
I also found and tried flashing a WW recovery but that didn't work either. I'm wondering now if I got the 615 software by mistake.

Lenovo Tablet 2 1050L boot failure after attempted root

hi - I hope someone can help me. I have a LTE enabled Lenovo Tablet 2 1050L which I attempted to root using the instructions given here ... https://forum.xda-developers.com/thinkpad-tablet/general/how-to-root-yoga-tablet-2-t3251571 ... but I have managed to brick my device. I successfully installed SuperSU but then read that Magisk was better and tried the same procedure with that but it didn't work. Now when the tablet starts up, I get a message which says ... "EFILINUX ERROR [android_image_start_buffer:737] boot image digital signature verification failed : 0000001A" which appears over the initial Lenovo splash screen. I then get to the Android system recovery menu but I can't get the table any further than this. I have tried wiping data / factory resetting but this does not work.
I can boot the tablet into recovery mode using CWM or TWRP but I have no idea what to do now. I guess I shouldn't have messed. I hope someone can help - I've tried the official Lenovo forums but no one has answered in a week.
Kind regards
I've downloaded this ROM ... lenovo-forums.ru/files/file/1074-yoga-tablet-2-10-yt2-1050l_s100192_151119_row_los-50 ... and flashed this onto my tablet using the Intel flash tool and everything seems to be back up and running.
Can someone confirm that this is safe to do? Can I trust this ROM as it's not from an official source?
Thanks

HELP please... how to stop boot loop

Thank you in advance for any help you can provide.
I successfully rooted my Zenfone 3 Max (ZC520TL) using Magisk, but wanted to restore the phone back to its factory firmware. I used the uninstall option in Magisk but this reported that it could not find the backup boot image. Unfortunately I then made the mistake of following unroot steps on other sites rather than this excellent resource. Long story short I somehow managed to lock the bootloader again so when I try to use fastboot to flash any image I get the error "FAILED (remote: not allowed in locked state)".
When I turn on the phone, on the ASUS splash screen it says...
Red State
Your device has failed verification and may not work properly
Your device will boot in 5 seconds
… ie boot loop.
Q) What can I do to get my phone usable again? I searched this site and found lots of info on how to unlock the bootloader and how to root, but nothing about how to stop the boot loop.
I do have access to the Recovery mode and see options such as "Apply update from ADB" and "Apply update from SD card" but I am unsure if these will help?
Thanks again for any help and/or links to solutions on this site that I missed.
I was caught in similar situation, due to unsuccessful flashing using asus flashtool, I ended up flashing stock firmware (not the raw firmware) via recovery and everything was back to normal.
Thank you... but...

Thank you @sanctitude888 so much for your help. I'm new to rooting but keen to learn. What's the difference between "stock" firmware and "raw" firmware? For example I can download the device firmware from ASUS and extract the boot.img file (ASUS no longer provides the recovery.img file) but is this considered "stock" firmware or "raw" firmware?
You also mentioned you flashed via recovery. In Recovery mode I see multiple options such as "Apply update from ADB", "Apply update from SD card", "Mount /system", etc. Could you please be more specific on how you did the recovery please?
Thank you for your help.
Kind Regards

A20e (SM-A202F) stuck in download mode - error validating footer

Hello, i hope someone can help me. My goal was to install lineageos on the A20e. So i unlocked the bootloader succesfully. Then i wanted to install TWRP. I used heimdall for flashing (with: heimdall flash --recovery twrp.img). The process ended without any errors. But since this point the phone stuck in download mode. When i restart the phone (volume down + power) the phone runs rapidly into the download mode. On the top left corner it show an error message (look at the screenshots). I tryed to flash twrp again for two or three times and one times the orange recovery - the results are the same.
I can still reach the phone via heimdall or odin. i have downloades the latest stock rom. So i hope to unbrick the phone - but until now i have no idea how to do. Please tell me, if you know some hints. You can also post if you think its hopeless and there ist no way to unbrick the phone.
Update: I have flashed the stock rom via odin succesfully. now it starts normaly. Do i want to do a next try ;-) ...
Thread can be closed...
Thank U
Jan
