P9 Lite cannot flash stock firmware

I have a Huawei P9 lite. (VNS-L31 dual sim) . I tried to install medrom 3 and after flashing, phone didn't boot up. So I flashed b161 firmware again using 3 button method and phone booted up. Then I realized I couldn't add my google account. After searching on xda I found a method to fix that.(flashing oem info ). But after doing that, when the phone boots up after the huawei logo the error message which says "your device has been unlocked" has become red.( Usually it's yellow). And in about phone my model number has been changed to something like hi6250 or hi650.( Can't remember the exact thing). Then I tried to reflash my b161 firmware using 3 button menu and voila. It says incompatible version. I can't flash it. Then I replaced my build prop with my friend's phone's build prop. But unfortunately it has the B151 version. Though I have B161 version installed, my about phone says it has B151 version. And I can't flash stock firmware using twrp or dload method od any how. Please help

That's normal if the message is red, it means that the bootloader Will be relocked.
Now for the build prop, download b161 version, use huawei firmware extractor , extract boot.img system.img and cust.img
And by fastboot type :
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot reboot
And voila, b161 is installed in your phone !

If fastboot say "FAILED (remote: Command not allowed)", its because your bootlaoder is locked, reunlock it !

In TWRP it says unable to mount Data :/

Code:
fastboot oem unlock XXXXXX
fastboot flash recovery recovery_stock.img

Unable to read/mount data says your encryption key got changed by something, whatever. You need to Wipe Internal storage and flash twrp again ( I recomment matic`s ) Reboot to recovery again, if you got one, flash a flashable fw via twrp. I Dont know if the stock recovery Accepts a fully wiped intern storage, i guess not and it declines the update.app method.
In the best case for sure you recover an older backup to get the Same enc. Key back

Try to hold Vol+ and the power button and if you enter in Huawei recovery, select wipe data / Factory reset

[Solved] Bricked P9 Lite

Hi, i have a big problem: my phone isn't starting up anymore. Before bricking my device, i was in b160(VNS L-21), then i decided to upgrade to Nougat. So i unlocked bootloader, flashed twrp etc.. Finally i got N working, after that i flashed Revolution twrp and ROM, everything fine. Then i decided to format data, just to get a "clean" ROM, but after this, my phone fell in bootloop and, i don't know why, i couldn't even get into twrp and if i try to boot into it, i just get stuck in the yellow text "Your phone is booting up..." forever. So i downloaded b160, extracted update.app and flashed system, boot, cust and recovery to try to get as stock phone was, but after that i couldn't boot into system: i just saw the yellow choices menu stuck with the same text "Your phone is booting up...", can't even see Huawei's logo. I tried to flash twrp for 6.0, but i couldn't boot into it cause it was replaced everytime by eRecovery. So i tried to install b160 from dload method and it worked but bootloader locked again and i don't have the password anymore, and after Huawei's logo there's just a black screen forever. I heard about some kind of "oeminfo.img" to flash before downgrading from N but i didn't do that cause i couldn't access twrp after formatting data. I tried to install via ota b100, b120, b130 without success, they all say incompatible firmware when i install them. I can just install b160 or b161 but they don't boot up. Please help me if u can, i'll really appreciate it

Try fastboot getvar all . Maybe it contains all the information you need
if not, dc-unlocker will do what you need. I've bricked my device and with their soft I've managed to write the full img. You should try only to unlock the bootloader service from them

You can look at the package of your P9 Lite. There should be a sticker on it with your IMEI.

Thank you! Now i have IMEI and Serial NR, i just need Product ID. Is there a way i can get this?
Edit: I DID IT! YAY! I got bootloader unlocked, i used Huawei Product ID Generator, and typed "HUAWEI Y300-0000" instead of "HUAWEI VNS-L21" in Reformatting Lock Huawei's page, and it worked like a charm! Thank you for your help guys, you're the best

Huawei p8 lite Bootloop Fix

so i had a p8 lite wich i tried rooting and it got stuck in a bootloop.
this worked for me
WARNING: this does delete everything you have (actually that is already gone)
(read all the way before doing anything)
first i set up adb & fastboot on my pc
https://youtu.be/UN7XW4HnFT8
2nd i downloaded stock firmware from huawei site ( you can also get this from rootjunky)
3rd i used HuaweiUpdateExtractor to get the recovery boot system and cust out (out of UPDATE.APP the one from the firmware)
4th i booted my phone into fastboot (i connected my phone to my pc first because otherwise i couldnt get into fastboot mode)
5th u start the command prompt in the adb&fastboot folder and type these commands (if you dont have custom recovery or custom roms you can skip to 5(i think i didnt do those)) :
1 adb devices (if it doesnt find it wait some time or reconnect it it will pop up sometime)
2 fastboot erase cache
3 fastboot flash boot BOOT.img
4 fastboot flash recovery RECOVERY.img
5 fastboot flash system SYSTEM.img
the system .img is too big so it will go in 6 parts and will often fail but just keep trying make sure to wait long enough because maybe it is still busy
6adb reboot
it should start up now.
these steps worked for me also when i did step 2 i could get into Erecovery wich i could before but now i could erase cache and something else and do a factory reset just press erase on everything then continu

VNS-L21 TIFU - wrote wrong cust.bin and oeminfo - what to do?

So... I tried to get the P9 lite to custom Nougat ROM.
Unlocked bootloader using SRKtool (found here ) and flashed TWRP using the same tool.
Installed SuperSU. Made TWRP backup of all partitions (including cust and oeminfo).
The post suggested that stock Nougat ROM should be installed first, and then the custom ROM. But my model was different than the generic EU, so I thought I should update it, right?
Without much thinking I used the SRKtool again to flash oeminfo/custom.bin, and didn't even make backup of the files
Now my phone thinks it is hi6250 VNS-C432B140.
After boot message "Your device has failed verification and may not work properly." was displayed and boot was interrupted with "Type your password to decrypt storage" prompt. After formatting data partition system boots.
I can't boot into TWRP recovery.
I can't flash any partition with fastboot (Error: FAILED (remote: Command not allowed)).
Any ideas how to get oeminfo back to VNS-L21 and/or restore TWRP backups?

huawei p10 lite

any one help me my phone cant inter to twrp (remote: partition length get error) ) or erecovery and cant update with dload sdcard and cant flash it with fastboot and stay at dead screan and reboot
plz help me

The 1st thing you will need to do on any locked device is to unlock the Bootloader before you continue.
To unlock Bootloader you will need to use any of the Huawei paid services in order to do so.
Several are available for that and will need to check for that online.

now i unlocked my dvice and
i flhashed it with this method after they dead
and i flash twrp
and i flash oeminfo-p10lite-Emui 8 C432.rar with twrp
and now i download th full ota firmware but still cant flash it whith hwota method thay tell me chen they copied the updat fille that have no more space can you halp me plz

Try different Firmware. Sometimes there is a problem with that. Try to search for others that are good as well.
