PRA-LX1 Prague-L31 kinda bricked... - P8 Lite (2017) Discussion

Hi there, so I've kinda screwed up my P8 lite 2017 (going by the IMEI check on huaweis site its a "HUAWEI P8 lite 2017(PRA-LX1)" model "Prague-L31" by trying out the experimental TWRP, only seeing encrypted data on the sdcard and trying a factory reset in that TWRP. Now I would love to just flash boot/recovery/system/vendor from fastboot, the main problem is - I havent found a update.zip or update.app for the Prague-L31 version. I've tried a few imgs from a few different versions and I basically always get the eRecovery factory reset to 99%, but thats it - **** doesnt really boot at all. so yeah. any tips or links for a Prague-L31 firmware? I'm also kinda new to the ****ton of different versions Huawei seems to have of its phones, is there just a different PRA-LX1 rom that should also work with the Prague-L31? I've already tried Prague-L21C185B173 and PRA-LX1C33B132, which were the closest things that did show up in the firmware finder - and like I said, I only got to the 99% factory reset with the boot/recovery/system of those two - vendor failed because fastboot gave me an "Command not allowed" error in both cases...
Oh yeah, and it's a Dual SIM

By the flashing your phone is locked again. You must unlock it by huawei unlock code. Then follow the instructions [How to unbrick] in this thread:

The dload method no works with this nougat device.

P9 Lite 2017 BootLoop

After installing twrp recovery i decided to install SU too. After that my phone is stuck in bootloop, before SU installation it worked just fine (with just the twrp) ;[
So here's my phone info (all i could get):
Model: PRA-LX1 (other ppl place here some diffrent numbers but i dont know where to find them since i cant even start my phone)
FCC ID: QIPRA-LX1
Well if someone could find a stock frimewere (or pre-rooted custom rom that would work on this phone) and give a link to it i would be greatfull couse i searched a lot and i'm still with nothing.
Now im left with empty brick with no OS at all...
Help! ;[
Maybe you should try this, it may find the proper firmware for your device.

... But this is P9 Lite "2017" and what i heard is that this model comes with name of P8 Lite 2017 and if im not wrong there is no P9 Lite "2017" thread just P9 Lite which is completly diffrent device!
Let's do this in a diffrent way...
If there is a person who owns the same phone and the same model PRA-LX1 which is the only thing written on the box,
then i ask you to do a twrp system backup and maybe give the file to me.

Yeah, with flash. Search universal flashboot anf than flash everything in order (these are not the orders, just an ex) flashboot boot boot.img flashboot recovery recovery.img etc(extracted from the zip file, maybr with huawei extractor)
But try to update you're TWRP, either to personas one or OpenKirin's TWRP, you should not have any problem on TWRP 3.1.1-0
Quick update nothing new, nothing works just gonna go to huwaei service room and hope that they can fix this... :[

First.. i supose you have TWRP ...
So, if im not wrong, your phone use 3 files to install the firmware ( like P8 Lite 2017 )...
Must be like this:
Download the 3 zip files (update.zip, cust and public data) of the firmware you want to flash and copy them to your phone’s memory.
Unplug the USB cable and power off your device.
Now hold Vol up + Power keys for a few seconds to boot into TWRP mode.
In TWRP, go to Install and flash the update.zip package.
After that, install the remaining two update files (cust and then the public data package).
Wipe the dalvik cache( or do a factory reset ) and then reboot normally into the new system.
Now the ROM... i don´t know where you can find it, sorry ...

Soft Bricked P9 L09 C150

UPDATE 2: Some things can not be fixed without proper tool. All i am left is to send it to service.
Which i did. Talked with a guy, explained and he told me he need to see it and test it with some tools. If can be fixed COOL if not i will sell it for parts and **** myself. Apperently some things need to be left to proffesionals.
PS. Will never get Huawei again
UPDATE: After trial and error i have TWRP instaled. Problem is i can't flash any rom because i got failed to mount /cust ,/vendor/ product (invalind argument) error. Also can't find stock flash rom for L09C150
Hello, i have problem with my phone, and this is 2nd night i spend working on it. Would appreciate any help!
Phone before trying to do anything: L09C150B367, Phone is from Hungary on Telekom (Pink T logo).
Tried to follow debranding guide (https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523) because i am sick of not having updated and unlocked global version. It's been long since i did anything with android and root so i tried and found guides on XDA.
Steps i did: found code for bootloaded, unlocked bootloader with SRK tool and instaled TWRP. Downloaded C432 and placed to SD. Trying to force update with Vol+,-, and power combo but update stop after 5% and say invalid software version. Somewhere i read that root is needed. Tried to root with SRK (Couple of times and different guides), not working for some reason. Phone is still unlocked with TWRP. Read somewhere (it was 3/4 am this night) that full wipe might solve it (note, i could boot into old OS). Did full wipe on TWRP and voila, not working. Can't even log on because no OS detected. Tried to find stock firmware to flash from SD card, no luck. All links i found either don't work or my recovery have ,,not correct version" error.
Now i have unlocked bootloader, custom TWRP recovery and no OS..essencially highteck-flashy brick.
What i want: Stock unbranded EU firmware.
Ps. Only phone, i refuse to burn 250e
If you are kind and free and KNOW how to do this, you can contact me via Discord and talk me trought this!

Huawei p9 always rebooting every 2 minutes

Hello everyone,
I'm new in xda's forum and so that's my first thread.
I hope you can help me.
I have a Huawei P9 EVA-L09C02B357 that lately it automatically reboot about every 2 minutes. The interesting things is that it happened only if I boot the ROM (stock or not). But in recovery mode (or erecovery) or fastboot mode, this automatic reboot doesnt manifest.
All is started when I have tried to install RROS Nougat on my phones and it was working when i tried to turn off the phone and then turn it on but nothing, the phone was stuck on boot phase.
I decided to switch data file system from f2fs to ext4 and then reinstall it as the guide explains.
https://forum.xda-developers.com/p9/development/rom-t3606185
The ROM worked correctly except the fingerprint sensor.
During the first configuration, it scans my fingerprint but for a bug, i couldnt go over the first scan.
Searching on the internet I understood that the problem could be the modem. But for a mistake I have flashed the wrong fix for the modem (it was for another phone, don't ask me how I didnt notice it).
Now even with stock rom or custom the phone has this automatic reboot. Particularly the stock rom has many bugs every time i flash it, like: there isn't the IMEI, there aren't any preinstalled apps, is really slow in some situations and the default keyboard is the voice typing...
I think the solution is to flash the stock modem, but when I try to flash it via fastboot, it says: "No suitable files selected. Check profiles.xml".
Thanks in advance
P.S. sorry for my bad english :C

UPDATE
Thank you so much vampirian!
I have successfully installed android 6 and the automatic reboot is gone.
Now i'll try to update it and probably retry to install RROS .

I know I don't write a lot of things or give you all the links. But it was good for you to research and learn more about your device good job and good luck with rros (although is dated and its not really worth, but that's just my opinion )

This is not the serial number (of your device) but the stock firmware build mame/number
If you debrand to c432 (EU) from your c900, you will automatically receive (must have SIM card in) OTA updates first to b242 (over your b182) and then further OTA updates up to b399 or even b502

If you have debranded to c432 as suggested in my previous post, let it update as far as it gets (b398, b399 or even b502).
Once it stops receiving OTAs, perform Hard reset with wiping Internal memory (you can do it from Settings or from eRecovery)
Btw, if it attempts an OTA but it fails, then go back to the updating screen and choose Full update, instead of (default) differential update.
Which ROM to suggest you - Magic Rainbow v4:

Now the phone is installing the b395 update. Is the hard reset necessary?
I knwo the existence of Magic Rainbow but i didn't know that it is based on Emui. I'll download it because i guess it is more stable than RROS.
It seems that i cant go over b395.

Are you now on EVA-L09 c432 b395, exactly as that?
You do not receive further OTA, or you received OTA but it failed (in that case force Full update as suggested above)?
If you're really not receiving OTA b398 or b399, try Hard reset with wiping Internal memory - if still mo OTA, install b398 by HWOTA method

Once you reach b398, you're ready for MR v4.

If you boot to eRecvery ( Vol+ and Pow) you will find Hard reset option.
Similarly, under Settings /Advanced Settings/ Reset phone there is also hard reset option - cannot tell you better details, I have TWRP and MR v4, I don't have these options.
Also if you 'dial' ' *#*#2846579#*#* a hidden Project menu will open, with Restore Factory option

Both two last options as listed (Settings and Project Menu) are present in stock ROM.
And you can boot to eRecovery as above - shut down, then press and keep pressing Vol+ and Pow together
If not OTA, then the best way for manual updating is HWOTA, I gave you the link also above
But still, you didn't confirm, are you really on EVA L09 c432 b395, ie, you are not on L19 (by mistake)

I was on EVA-L09 c432 b395 and now I'm on b502. I tell you what I did.
I tried to make a reset bt the Project Menu option but, the reset it didn't gave any update...
So I tried with firmware finder (android version) and I used the DNS method. I have chosen the b397 OTA and the updater found it.
During the download, it arrived at 25% and suddenly the phone has found the b502 for a total of 4 patch to download together (I dont know how to explain that thing).
After download the phone reboot for installing phase but it failed... and on boot it appeared a red warning, then i went to erecovery, shut off the phone and go to recovery mode for a factory reset.
Factory reset was a success but on boot the red warning still appear but i tried to continue to boot... fortunately it was all ok but the phone was on b395.
It magically appeared the screen for b502 Full-OTA update and now I have it!
I wouldn't understimate you but I always prefer to try solution by myself.

Restored Stock Rom through TWRP not booting

REALLY IN NEED FOR HELP:crying:
Followed this guide youtube.com/watch?v=2tAeNZdTyeY to install Resurrection Remix on my P9 EVA-L19. After booting the phone, it is just stuck on the boot animation. I panicked and restored to the stock rom. After booting the device, it gets stuck at the "unlocked bootloader" screen.
So I tried to restore the rom through the eRecovery process but gave me an error.
So then I tried the dload process where I copy the UPDATE.APP to my SD card(FAT32) and failed. it stopped at 5% and said "Software install failed!"
I really don't know what to do next.
Any suggestions will be highly appreciated.
Thanks.

There is a RR thread for P9, I'd suggesr to ask there about the RR installation and issues (these topics opened under Q&A practically nobody reads, specially not those few who know more about RR)
https://forum.xda-developers.com/p9/development/rom-t3767344
For safe reverting back to stock you should have used HWOTA method (maybe it will still work if your Bootloader is unlocked and/or you have TWRP for EMUI 5.x)

I don't know if that is possible, I know it's too late now but whenever I'm going to play with ROMs or so, I save screenshots of my Settings/About and all things like that (IMEI, etc), just in case (like this case).
Maybe you can figure out by:
- was it International cust c432, Mideast c185, or provided by some operator, see
https://www.huaweiblog.de/firmware-update-was-bedeutet-cust-emui-und-co/
- have you debranded the phone
- btw, before installing RR did you check if RR is compatible to install over your (at that time) stock ROM
- Have you installed a firmware from FirmwareFinder, by DLOAD, HWOTA or other methods
Eg, if it was c432 and if you did not manually update, it was likely b393 as the last approved build for L19

I fixed the phone! I used the link u shared about the HWOTA and followed the steps. I did a lot of research about the model number and the cust and found out on the Huawei site that my phone is the EVA-19C185. So I installed the update and it worked! Thank you so much for your help. Really appreciate it.

Huawei 20 mate lite soft bricked

Hi , soft bricked my Huawei Mate 20 lite. Model is SNE-LX1 HW/EU. Did a firmware upgrade to frp unlock Since then get black screen with yellow text saying a new OS has been installed and device reboots in recovery. Reinstalled already different firmware versions via sload SD card upgrade + use fastboot to unlock FRP code. Fastboot unlock command completes successfully and device does automatically a low level format to then come back to "different os installed message. Anyone advice ?
Hi phitilip, I can't help you on the bricked part (yet). I assume you tried to use Huawei Hisuite software to restore the original firmware so you could possible start over?
I recently got my Mate 20 Lite and haven't messed with it too much (yet!). I do have a question for you though. How did you get the bootloader unlocked? The only way I have found is to pay some random person/company for an unlock code. Trying to avoid that. By the way, I'm in the USA and also on SNE-LX1 with a 'global' designation.

Hi , the unlock code I purchased was for the FRP unlock because I was told would solve my problem and although the code is correct and allows to do a factory reset it will not solve the "you installed a new software ..." message. When looking online I found that I probably installed the wrong region code firmware but tried everything and cannot get the phone to boot normally. Any advise would be very appreciated.
Can you get to recovery or download?
I'm much more familiar with Samsung devices so my frame of reference is there. How did you flash the new rom? What tool? Where did you get the rom from?
Since you can reset to factory, but that still gives you the error, the only way I can think of so far, with the very little experience I have with Huawei devices, is to find two things if you can. First try to find a 3rd party recovery like TWRP or CWM or possibly use the tool you used to flash the ROM. Flash that if possible to the recovery partition. Then find the original factory firmware for your device and region, even if you have to go beck to Android 9. Then from recovery, or the tool you used to flash new rom, flash that. I'll do some research and see if I can find anything you haven't. From my limited searching for my own Mate 20 Lite, there doesn't seem to be much out there. What's your objective in all of this? Are you just looking to root? Did Hisuite play any role in this? The good news is I have the exact same device as you so I can try some things while it's not bricked
