Messed things up with upgrade/downgrade? - Huawei P9 Lite Questions & Answers

My wife got a P9 Lite L31. I wanted to upgrade to Nougat. I finally succeeded, but after that I messed things up. I tried to do a clean intall with a update that wasn't ment for this.
In the beginning I could still enter the Nougat recovery, but I wasn't able to reinstall the update.zip. The device wouldn't boot, etc.
I tried to do many different things, but at this moment I cant enter TWRP anymore, I can enter fastboot and is says:
PHONE Unlocked
FRP Unlocked
But flashing an other TWRP recovery doesn's work because I get an error:
(Remote: Command not allowed).
Also relocking the bootloader doesn't work because is gives the same error as the one above.
I can't flash a OEM file through fastboot because it gives the same error as the one above.
I can't use HiSuite because it says it does not support the phone.
I don't know what else I can do right now.
I tried the 3 button method, but I can't get in the official recovery. The phone reboots to some kind of recovery where it wants to update the recovery through wifi, but it ends up with an error that it can't fails to get the package info. But there is no option to do a factory reset (I've put the MM update.app file in sdcard/dload folder).
Any ideas what else I can do to recover the phone?

Unlock the bootloader again.

Ok, did not expect to do that again, but I did it.
What's the next step? flash a nougat recovery? flash a oem recovery?
Fastboot now says:
Error!
Func NO: 11 (recovery image)
Error NO: 2 (load failed)
Looks like fastboot isn't recognized by the computer anymore after the re-unlocking of the bootloader.
Windows device management also doesn't see the device. Not even as an unknown device.... Looks like the bootloader unlock completely bricked the device.

Well.
You must change your motherboard.

As per usual, your comment was of no help at all.

Take a look to this thread, it seems similar to your problem https://forum.xda-developers.com/p8lite/help/stuck-rescue-mode-screen-please-help-t3244872

Try to discharge your battery by leaving it on Fastboot mode.
Charget the batery and let it boot itself.
If it boots in the software, it will be very easy to fix. If no, then changing the motherboard is required

To be honest, nothing.
It can do two things, you can let it boot and then it says it's booting, and that's it (after the warning that the bootloader is unlocked), or I can boot into fastboot but the phone is not detected by the computer. Device manager doesn't see the device at all not even as an unknown device. Nothing. So no way to flash anything using fastboot. KI also can't get into the fastboot&repair.
So yeah, I decided to send it in for repair.

Stuck on bootloader (nexus 6p) ..... Plz help!!!!

I recently tried to flash PureNexus rom from chroma rom.... I know I did a clean install because it was successful but when I hit wipe davik it got stuck on the boot screen. When I restarted it apparently wiped my internal storage. Now I get this message "Your device is corrupt. It can't be trusted and may not work properly."
The device is now LOCKED and NULLED... adb reboot bootloader does not work....
Cant flash images
CANT UNLOCK
When I try to unlock it "fastboot flashing unlock" i get this message "FAILED (remote: device is locked. Cannot flash images)"
I can't go into the device and enable OEM cause there is no ROM to get into.
I can't drop files onto my device because it's not recognized by my device.... BUT ANDROID ADB INTERFACE shows up under device manager.
ANY HELP IS APPRECIATED?
I think you were on the wrong vendor which caused this so you can't get to the boot loader? Did try doing it manually not via adb

How did your bootloader get locked? That is something you have to intentionally do. And I know you must have unlocked it because you were using a custom recovery.
---------- Post added at 08:21 PM ---------- Previous post was at 08:16 PM ----------
This is right from Heisenbergs guide
Important: do not lock the bootloader unless you have first flashed the stock images. Locking the bootloader while you have a custom recovery installed can result in a brick. Please also note that the locking procedure will wipe all user data from the device.

Ya, not sure how your internal storage getting deleted has anything to do with your bootloader getting locked.
YOU had to have locked your bootloader.
And as to why you did that, I have NO idea... And as of where to go from here? Also no idea.
Good luck man, that's a crappy situation, hope you get it fixed somehow

Need help

Hi,, I need help, don't now what to do, I run King root on my phone, xt1562, and **** up everything.... you can see in the pics.. I search, and I can find solution, so please somebody give me the solution for this problem. I tray with adb, mfasboot, rds life to refresh on lollipop without results.
Not sure if i understand your problem, but have you tried to flash twrp to be able to boot in recovery and then flash a rom
you need to unlock your device first then flash twrp recovery , and install supersu to root the device.
try this: http://forum.xda-developers.com/moto-x-play/general/untested-how-to-root-moto-x-play-t3211941
I tray that, but don't work for me, before I start with King root I alow OEM unlock on the developer settings on the phone, and now Adb don't recognize that and ask for OEM unlock, and it impossible now cos phone don't work

Flash factory firmware, it's pretty much the only thing you can do with locked bootloader. And don't use kingroot any more

Did you originally have Lollipop or MM. Here's MM firmware:
If it's european XT1562, single sim, try this one:
http://www.filefactory.com/file/1ub...MPD24.107-52_cid7_subsidy-DEFAULT_CFC.xml.zip
If it's asian, dual sim, this one:
http://www.filefactory.com/file/49g...MPD24.107-70_cid7_subsidy-DEFAULT_CFC.xml.zip
(double check it, for you own safety)
Make sure you've got moto drivers and use fastboot or mfastboot.
What messages did you get when flashing before, what did it say exactly after executing fastboot commands?
Tnx
Before, phone was originally on lollipop, and receive Ota update on MM6. 0.1.
I tried to root this phone through this bull**** Kingroot.. And it failed.. Later on when i restarted the phone it got bootlooped and is totally bricked! i get this error- Startup Failed: Your device didn't start up successfully. use the software repair assistant on computer to repair your device.

If you installed MM OTA you can't flash Lollipop firmware, it must be MM (generally speaking). Get into bootloader and try to flash MM with fastboot.

I can see it boots in fastboot mode, which is good, but your firmware is messed. Is your phone sim-free or carrier branded? If it's sim-free you should be able to flash the firmware I linked.

Can't unlock bootloader, can't finish OS setup

So I upgraded to Nougat on my P9 Lite, unlocked boot loader, used twrp, flashed roms and everything went smooth. Saw a more up-to-date version with no bugs, so I had to downgrade to MM first.
I followed a guide, but I messed up somewhere and ended up having my bootloader locked, and I can't access the OS to enable developer options and oem unlock from settings. The reason why I can't access the OS is that I am stuck in the setup. I am stuck at the part where I have to sign in to my google account. It doesn't show a keyboard, only a microphone, and I can't use that for my password (it won't let me).
Any ideas?
TL;DR messed up during downgrading from Nougat to MM, now TWLR is gone, bootloader is locked and my main issue is that when I get to the google account sign in part during OS setup, there is no keyboard (I can only use dictation) so I can't sign in... So I'm stuck
Also, can I unlock bootloader without access to OS, without being able to navigate to settings, enable developer options and then oem unlock?
1. Stuck in OS setup? Signing in to Google? Hey, it's not obligatory, can't you just skip it?
2. Flashing ROMS locked your bootloader, it's normal, but I'm sure it didn't change the "oem unlock" setting you had surely enabled before. Go to fastboot mode and check Bootloader and FRP status on the bottom of the screen. If FRP is unlocked, you will be able to unlock bootloader again.
3. If you have your TWRP gone (flashed by stock ROM), flash the recovery partition manually - fastboot flash recovery TWRP.img (download from Meticulus Project site).

It is obligatory, I couldn't skip it. I tried to use other methods of signing in, but then it asked me to reset password at the end.
Both Phone and FRP are locked
I think I have missed this, but I can't do it via fastboot because I keep getting "Command not allowed" whenever I try to unlock bootloader or do anything via fast boot.
Also, thank you so much for your time and input. It is much appreciated.
That's weird, I flashed my phone several times with different ROMS (not Nougat) and this setting (oem unlock / FRP unlocked) stayed enabled. Don't know where it sits then and how to change it without getting inside OS. But - what about TWRP? Oh right, you won't be able to flash it without unlocked bootloader... Oh, crap. I would try SRK Tool for Huawei to play with bootloader, it uses fastboot so shouldn't help, but maybe, just maybe? Maybe try flashing whole ROMs through dload folder on SD? Stock 120, 161, Nougat, I would try these. I hope there is some way to unlock FRP, probably it's possible in DC-unlocker (it's a paid software).

Yes, it's very weird. I haven't done the process a lot. But I've flashed a couple of phones I had before, went smooth. Nothing major like this happened before.
I will consider the SRK Tool and I did not know about the DC-Unlocker tool, thank you for telling me about it.
Flashing whole roms through dload folder only works with Nougat for some reason, and I keep getting stuck in the signing in problem because of no keyboard, someone told me that's incomplete software, I'm hoping that's the case, any ideas where can I get it from?
Again thank you Jagiel88 for your time and advice xD
No problem, unfortunately I haven't tried Nougat yet, so search for help on down/upgrade Nougat beta <-> Marshmallow threads .

How to uninstall CWM from Huawei P8, B200, rolled back from MM

I don't have an unlocked bootloader and i flashed the CWM. Now when i try to enter the recovery mode with buttons, nothing happens just turns the phone on normally. I searched for stock recoveries, but didn't found nothing.
I have GRA-L09, B200, Europe Open
Thanks for help!
To get an unlocked bootloader you must go to settings> about phone> build number
and then press build number 7 times
after you did that exit out of about phone then click on the newly-appeared 'developer settings'
there you should find OEM Unlocking and Enable USB Debugging
You'll get it from there.
I have the Dev Ops, but don't have OEM unlock.
But shouldn't you already have an unlocked bootloader to have DevOps?
Don't know. I don't typed any code in to unlock bootloader.
Are you sure you have DevOps?
---------- Post added at 01:58 PM ---------- Previous post was at 01:55 PM ----------
And also try to do it not with buttons, but with your computer
I don't know the script for how to boot into recovery mode but to fastboot, for example, you'd type in >fastboot
when your phone is connected to your PC via USB.
Y'know, just search up 'How to use Recovery Mode' - maybe you just did it wrong
Didn't tryed it w/ adb yet.
ADB didn't worked. I'm trying a full hard reset..

That means you have a locked bootloader, so CWM didn't install successfully.
In other words, you need to unlock the bootloader first in order to successfully install CWM.
So, 1st step - visit the Huawei unlocking code request page, taking your time to fill in the form accurately & submit it.
[Btw, if you don't already have a Huawei ID, you can register for one here: http://www-file.huawei.com/en/my-huawei/register
Then use these login details in the above link to request for the unlock code]
2nd step: Once you receive the unlock code from them, use it to unlock the bootloader by issuing the following command in fastboot mode [the asterisks (*) represent your 16-digit unlock code]:
Code:
fastboot oem unlock ****************
Now you can attempt to install CWM. Where are you getting the CWM img file from?

Ok, so it appears you may have corrupted the recovery partition.
Is the phone otherwise booting into the system & functioning normally?
Also, can you tell us what you are wanting to ultimately achieve by installing CWM?
Just to confirm the bootloader is unlocked, run this command in fastboot mode & let us know the result:

As the guys already said, you do not need to install anything in order to update an official rom.
So, let's leave out CWM, bootloaders, etc for now, & help you update only from B200.
When you try using TopperBG's method to update, what happens?
What is your current FULL firmware version? It will be in this format: GRA-L09CxxxB200 - if everything else is as I've mentioned, I'm interested in the Cxxx part.

1. You need to install stock recovery for android 5(unlocked bootloader is required).
2. Then you can use the dload method to update.
3. You can flash TWRP after that because no-one uses CWM.

No Recovery

I think i made i grave mistake. I want to upgrade my p9 lite to nougat so I decided to unroot my phone. The unrooting is successful with the device still booting. So next thing i want is to flash back my stock recovery so I can update my phone through OTA (this is where I made a mistake.) I tried doing it by flashing a full MM Rom that i got directly from huawei through dload method. The flashing went smoothly or so I thought. My phone got stuck in a boot loop and I cant seem to access recovery. eRecovery is also inaccessible so I tried reflashing the full MM Rom through dload method but I can't get it to work anymore. I tried it several times with no luck. I also tried reflashing meticulus' twrp through fastboot method but I always get an error saying "remote command not allowed". The bootloader is still unlock btw.
Someone help me. I don't know what to do anymore... :crying:

The bootloader appears unlocked, and says so, but it's not...I encountered the same situation with my colleagues device, you need to unlock it either way(careful this will wipe all your data if on nougat, but if on MM after unlocking keep phone connected to PC as it reboots and quickly press vol down+ power to get back to bootloader In order to flash TWRP, this will preserve your data partition and system), and try again, you need format that data partition by using changing format to f2fs then ext4...after this reboot, if it can't, reinstall the file In dload folder and go to stock recovery(disconnect phone from PC to do this if it fails) and do a factory reset.
.... if this fails, debrand And install MM or NOUGAT for your newly debranded system.
If this fails, which is highly unlikely,PM for un orthodox methods.

The problem is I cannot access recovery anymore. After trying to flash back full rom from huawei, i cannot access recovery anymore no matter how hard i try. eRecovery is also not accessible so i cannot turn off my phone. I tried flashing twrp trough fastboot i keep getting an error saying "remote command not allowed". Dload method is not working anymore. If only I can find a way to flash twrp, then I can restore the dump i made using meticulus' twrp.

Assuming that you have the unlock code, what happens if you try unlock bootloader again irrespective what status it is now?

It shows in fastboot that the phone is unlocked with frp locked. Unlocking it again through fastboot is not possible since I always get an error saying remote command not allowed.

Hi guys, i Got the SAAAAAME Problem, this is all about what i PMd to you danerrickcuba FRP lock and bootloader unlocked. can't go to recovery, but has access to fastboot and wasn't able to do anything to fastboot.
Already fixed my phone. Had to pay 15 euros for DC Phoenix (this software saved me from bringing my phone to huawei service center to have it fix. Thank god!) so I can fix my phone. Recovery, eRecovery, Dload method working, and relocked bootloader. Currently updating my phone through OTA. Tnx danerrickcuba for suggesting methods to fix my phone....

i have the same problem
bootloader unlock and frp lock ,bootlooping,rec&e-rec destoryed
if you do not log out google /shut down "find my phone"/check oem-unlock in developer mode before downgrading or flashing ,you will get "frp lock" warning
bootlooping may come from wrong update.app. eg. i use dload method to flash rollback(5.0-B300) pkg in EMUI4.1 , my rec and e-rec are destoryed
however, i think fastboot command could do nothing to "bootloader unlock ,frp lock,rec and e-rec destoryed ". i do not know how DC-phoenix fix this and i pay a new motherboard for my mistake
