I have successfully unlocked the bootloader and managed to install TWRP 3.1.0-3 but that's about it. I cannot install any other TWRP version but the one I mentioned. I tried installing Magic Rainbow custom ROM but it doesn't work properly (apps are super slow, entering developer settings makes the settings app crash, can't set a password etc.). So with that I can at least access the phone interface with limited options. Developer settings crashes when I choose it; if I can get through then I can't enable USB debugging, it keeps turning itself off right as I enable it. I can't use update function so I have to use 3 button installation, which randomly fails to work very often. Due to this I haven't been able to install any updates.
I kinda gave up on rooting already, I just want to get my old firmware back at this point but I can't even do that. SRKTools stock marshmallow recovery doesn't work either. It's as if TWRP 3.1.0 has taken over everything. On the rare occasions that I managed to get EMUI update via 3 button installation it would say that the update doesn't match the current version (or something like that). I tried using recover for b378 and managed to run the 3 button update but it always gets stuck at 5%. It gives up after a while, tries booting twice and then goes into eRecovery screen. My bootloader PHONE unlocked text is in red if it matters.
I've been actively trying to fix this for the last 11 hours (yes I'm not exaggerating at all). Please, PLEASE someone help me out with this!
I've also tried using the unbrick tool of the latest SRK Tool 2.0 for b378. It goes flawless, phone restarts and does a factory wipe but then doesn't boot after the Huawei screen. It tries booting twice and then it goes into eRecovery screen. Have I ruined some hardware here?
It seems like 3 button upgrade is my salvation and it doesn't work. Many times I hold it down, I get a slightly different screen but it again hangs at booting text. I managed to flash all recovery, boot and system image files and got the installing update screen in my b378 update, but it hangs at 5%. I couldn't even manage to get the installing update screen for common b136. Also when I try to flash system.img I get an error with flashing system which is FAILED (remote:sparse flash write failure).
First at all: The Magic Rainbow custom ROM is based on B383 so it wont work on B378 firmware thats your fault here.
Just flash the rollback package (find it in my signature) and after this flash B383 or if it not work start with B136. U have to do all with the dload method.
Fast solution?
https://forum.xda-developers.com/p9/development/p9-moonlight-rom-v1-0-b378-stock-t3567223
flash the B378 version. probably your problem is solved by this.
I'm very well aware that Magic Rainbow doesn't work with b378. That's probably the reason I have those issues with it. But it's the only way I can access the phone's interface in case I need to use it for a fix.
I tried flashing b378 already multiple times, without rollback and it did not work. Is it safe to use the rollback though? My oem is c432, would it create any issues to use that? Should I flash c900 oem first or can I go with the rollback right away? I literally cannot install any stock rom without having frozen/looping bootscreen atm so I can't complete any step that requires me to do that.
I've also tried flashing b136 plenty of times already. I can't even flash the system.img. I can't flash the system of any of the b100 series.

u tried the rom i mentioned?
it is safe to use the rollback package. any firmware after will retrive your oem to c432. so you dont need to flash the oem info package.
1. flash rollback package via dload (watch out to have only the UPDATE.APP file in dload folder)
2. flash B383 via dload (2 files need to be flashed!)
3. flash special SuperSU_for_EMUI5.zip
4. have fun
again if u can boot magic rom then you can flash and use Moonlight rom v1.0

I cannot flash rollback using 3 buttons method. I see the "your device is booting now" text and then it goes to TWRP menu. Nothing happens. This is what I mean with 3 button method not working. Every single update fails probably because of this. Is there anything else I can do to flash it?
I've also tried flashing b378 and then doing the rollback. Still doesn't work: It hangs at 5% as it did with the b378 update.
Also, is there a special way of flashing those 2 files of b383? Is it just one after another? I doubt I can flash them at the same time since they have the same name.
YES IT WORKED! Thank you the rollback actually made the difference. I had to go for b136 and then upgrade manually through there with the stock OS though. And I believe rollback changed the status to LOCKED instead of RELOCKED. And I was a complete moron for I couldn't do 3 button update because my cable was still plugged in. I had a moment of epiphany when I noticed what the symbol actually represents. It was like discovering who Keyser Soze was lol. Let this idiocy stay here for there might be others like me; this way they might fix it without embarrassing themselves like I did.
Glad it worked for you.
Next time just read the threads in this forum.
There are several toturials how to flash the p9 the right way.

Every time I try to flash, with 3 buttons method, it puts me "software install failed"
I tried to flash official rom with twrp but he can't finish the process.
I tried to flash custom rom. When I want to boot, he bootloop.
Hi,
I am at a complete loss and going round in circles. My phone has bootlocker unlocked message at moment. In adb fastboot devices finds the phone, but the SRK tool fails to find it sticking on 'waiting for phone'. I tried to flasg the Huawei rollback but that fails (presumably due to being unlocked). I cannot relock via fastboot as that gives 'remote: command not allowed' error.
Update
- I have just checked fastboot - it says Phone Unlocked & FRP Unlock.
- Next I used Huawei Update Extractor to get boot, recovery, cust & system img from the "HUAWEI_P9_Firmware_EVA-L09_Andriod 6.0_EMUI 4.1_C432B166_United Kingdom_Channel-Others" Package.
It seems I still cannot boot and device still says unlocked etc..
Update 2 :-
Copied the dload/update.app file from the HUAWEI_P9_Firmware_EVA-L09_Andriod 6.0 zip. Managed to get it to start installing, only to get Software Install Failed msg. However reboot let me start the phone. So currently have Build No: EVA-L09C432B166 on.
At this point I just want my phone either back to initial factory state or able to flash roms, whichever is easier to get to. Any help greatly appreciated. I've been getting nowhere following guides I have found, so would really appreciate some help here.
Thank You

Ok first of all, using TWRP back up everything you have there (backing up SD card isn't really needed unless you plan to wipe it too). Then, using TWRP again just wipe everything but OEM and SD card (external storage). Then, create a folder called "dload" in the main SD card directory and put ONLY the update.app in it (use the stock b136 as suggested). Now you need to flash a stock recovery using bootloader again. Just use the Huawei Update Extractor and get both recovery.img and boot.img from the rom that you're using to flash (in this case b136). Put them in the same folder as adb. Run adb cmd, write commands "fastboot flash recovery recovery.img" and then "fastboot flash boot boot.img" and finally "fastboot reboot". Quickly unplug your usb cable and use the 3 button force update (Vol Up+Vol Down+Power button all held together and don't let go until you see the update start). It should work without a problem if you had managed to wipe everything using TWRP. If it still doesn't work you could try deleting OEM info as well and flashing a new one (c432) which you can find on the forums. Back up is important in case it still doesn't work, you might need them to undo things.
If it boots, it means you've learned how to do it and you can probably unbrick it as much as you want haha. You can update to Nougat (7.0) and EMUI 5 using Huawei Updater 2.0 along with HiSuite, there is a guide here on the forums to do so by updating to b182 then to b360/b361>b378>b383 which I was unable to find for now. After that you can install a custom rom without an issue. I figured I wouldn't mess with it anymore but frankly it's likely that you are just soft bricking by skipping something very simple and failing because of that unless you went ahead and did things that you are explicitly told not to do so. If you end up having it unlocked/relocked might as well try and get a custom rom really.
If the update gets stuck at 5% or you have the icon of a usb cable end with a lightning on it your mistake is that you didn't unplug it. If the update keeps failing without these it's likely that you're using the wrong firmware and you could try using another one (FULL+PV+MV ones if you're going for a higher one). Or you could try to follow the rollback and then the update as I did. if you do the rollback then the update, your phone might get a LOCKED status again (yes not relocked).
If you are missing something or you think you have a stupid question and too shy to ask it here just PM me.

So you're saying that you're able to boot your phone on stock b166? Then update it to b182 first. I had to keep pressing the check update for a while before it popped up. I was busy at the time so I didn't mind the wait time but I bet you can do it faster forcefully, got to be a guide around here somewhere. Here is the guide to update it all the way to b383 from b182.

I'm on B166 currently. Phone tells me it has update for B182, on reboot I get the device unlocked message and it sticks on 'Your device is booting now'.
Also tried Huawei updater....that sticks at 'Listened on Port 41279'

Getting the device unlocked message shouldn't indicate anything, only that you didn't lock it again. It might be that you didn't install your current rom correctly. You could try flashing TWRP, backing up everything and then wiping all of it f. It means you'll be romless for a while but worst case you can recover what you backed up with TWRP and then flash it with a stock rom again. There are guides to flashing everywhere and I've made my own guide here. I can't really give you advice on your situation since I haven't ever been there. I just dabble with these things, so I can't really find a solution for everything.
You are connected to HiSuite while running Huawei Updater right? It needs to be able to see your phone (usb debugging on or HDB mode) and set to usage via proxy.

Run HiSuite. Make sure your phone is connected to it. Top right you'll see 4 buttons: 3 horizontal stripes, minimise, full screen and X. Press 3 stripes one and choose settings. In the first tab called General under the 4th section you'll see Proxy. Enable it and enter 127.0.0.1 for address and the given listening port as the port. Leave the username and password blank. Press apply. Then you probably have to choose the system upgrade from the main screen of HiSuite. I don't recall exactly but this is about how it goes.

P8 Lite, I can boot into Fastboot&Rescue, normal boot gives a black screen after the Huawei logo. Recovery and force download from SD does not work.
I can boot into EMUI recovery by holding Vol Up in Fastboot, which gives me the options of Reboot, Shutdown and "Download new version and recovery" (which fails).
I tried the Unbrick steps from the Mega-Thread, and also flashed the Huawei P8 Lite version of TWRP to recovery - but it still only loads the EMUI Huawei eRecovery. Bootloader is unlocked.
Any ideas on what to do next before my girlfriend is going to kill me?
I tried everything in this thread:
http://forum.xda-developers.com/p8lite/general/hand-fixing-bootloop-t3464740
to no avail. One thing I noticed is that the link given in the Fastboot menu links to a Chinese (?) website - http://zh.ui.vmall.com/emotiondownload.php?mod=restore - I'm not sure if this is indicative of me having a device for the East Asian markets and if there are any software differences?
Sorry for the triple post - now I actually managed to boot into TWRP (the trick is disconnecting the USB cable before booting into recovery), I wiped everything, re-tried the flash all from the Mega thread, and it's still not working - Huawei logo is shown, then black screen/power off(?).

Hi, when you power on your device to boot into EMUI, does it just show the red Huawei logo, or does it also show the boot animation (the same logo dancing and moving on the screen and then becomes static)?

Just the very static image, it doesn't even go into the animation.
Edit: this is a newly bought P8 Lite, the Box says Android 5.0, don't know if relevant?
by now I've wiped stuff with TWRP more times than I can count, and tried manually flashing the boot, recovery, cust and system of b132, b170, b190, and b564 to no avail

Alright, so, since you can get into TWRP, inside TWRP go to Advanced > File manager and get this file: /sys/fs/pstore/console-ramoops and paste it to the internal storage or the sdcard, then via USB paste it to your computer and upload it somewhere, I'd like to check it.

Yes, I found what I wanted, the kernel panics. What have you exactly done to the device? That would definitely help to know how to solve it.

I wish I knew! I tried to root it the same way I rooted my other P8 Lite, which worked fine in the beginning (unlocking bootloader) and ****ed up somewhere between pushing SuperSU to the device and executing it. Then I tried to flash stockrecovery.img back, and suddenly the device was broken. Next thing I did was follow the guide in the Mega Thread (I think resetting to b052) which didn't help either. Then worked my way through the suggestion in the other thread. :silly:
edit: judging by my google history, the problems started when the recovery returned a segmentation fault instead of installing SuperSU as it would've been supposed to.

It is very nice of you to look into this! Worst case scenario, the device was broken from the start and has now lost its warranty (though I booted it up once without problems right in the beginning).
For the main problem - which is my gf - I simply factory reset my own P8 Lite and put the stickers from the new one on it. Now I don't have a phone, but at least I get to keep my relationship
ninja edit: checking my terminal history, I remember trying to fix the not-installing SuperSU by trying fastboot -w and fastboot format cache as recommended elsewhere, but both failed
Playing around with it again, it seems the only fastboot commands working are fastboot flash and fastboot reboot, everything else is giving a "FAILED (remote: Command not allowed)" error, even for things like getvar
flashing b564 allows me to get into stock recovery, will try dload update now!!
EDIT: IT WORKS!!!
Things I learned from this:
- it is important to flash right update version
- use dload if you can boot into stock recovery
- recovery will only be loaded if not connected via USB, otherwise EMUI crap will launch
- vendors do not always have correct information on device package!!

For unbrick, its easy if your bootloader is unlocked.
Just need time and flash few files by adb (downgrade)and update your device's to the android version you want.
If you want I have all the necessary files.
After your device's is like at his first boot.

Hey guys,
This is a bit of a long one so please bear with me...
I have an EU EVA-L09 which was running EVA-L09C432B166 unrooted and with a locked bootloader. I decided to unlock it which I did successfully (Fastboot was showing both Phone & FRP as unlocked) and flashed TWRP on to it as well as BETA-SuperSU-v2.65.
After a few days with my stock email app not working and Battery Settings unaccessable since rooting (not to mention the warning message every time I booted my phone) I decided it wasn't worth it and wanted to remove it all and go back to stock. I was struggling to find a stock rom due to being impatient and just removed root via SuperSU app on my phone.
I found a stock recovery image which I tried to flash on to the phone using the BAT file (PASO 3 VOLVER A RECOVERY STOCK) which didn't seem to work. I also tried to do it via cmd line and was faced with "FAILED (remote: Command not allowed)." I also noticed that FRP was showing as locked now in fastboot. I did unlock it using DC Unlocker but it's still displaying as locked (after some research on the forum this seems normal.)
I tried to update to Nougat 7.0 by Wiping in TWRP and then installing Update.zip from another thread on this forum. This worked great but stupidly I forgot to install the EU pack zip which accompanied it before rebooting. Unfortunately this has now installed a limited version of Nougat on to the phone whilst simultaneously removing TWRP so I can't install the other zip.
I have tried to install the other zip and some old firmware using dload method but I always get stuck on 5%. I have also tried flashing TWRP again but I am facing the same , ""FAILED (remote: Command not allowed)" error. The error is also displayed when I try to re-lock the bootloader. The bootloader is definitely unlocked as I have checked with cmd line & the warning message is still being displayed on booting up. I have USB debugging enabled but am unable to enable OEM Unlock due to the option being greyed out (seems to be the case when FRP is unlocked.)
I can't do any updates using 3 button technique they all get stuck on 5%. I can't submit any flash commands in cmd.exe without getting the "command not allowed error."
There is a bit of hope because I can boot in to Nougat but it's very limited with no apps and no keyboard.
Can anybody help?

Hey @jcalderonv74 thank you for the response. I have just re-tried to do that on your suggestion and with the intermediate UPDATE.app in the dload folder on my external SD I get to the stage of the 3 button start up as per the instructions and Installing Update gets stuck on 5%.
I have noticed I do have access to stock recovery using "adb reboot recovery" command.
Any more ideas?

Hi, yeah I did use the rollback package @xtcislove and it would just get stuck on 5% using the dload method, and trying to flash it in command line would result in "Command not allowed".

Ok just for completion and anybody who is having the same issues as I have had with the same or similar model of P9, this is how I solved it (after a day without sleep and a couple of migraines). Please note this is only to be used if you have exhausted all other, free options on this forum as this is slightly risky and costs money. It's a last resort.
What you'll need:
- HiSuite installed but closed on your PC
- USB cable to connect phone to PC
- DC-Phoenix with an account with 15 credits (15 Euro)
- The DC-Phoenix guide opened at "Method 2"
- Firmware .img file from their database by clicking "Enter Support Area" button in DC-Phoenix (EVA-AL10_M00A056_Factory_firmware_Global_Nonspecific_Android_6.0_EMUI_4.1.dgtks)
- Stock firmware as an .app file on an SDCard in a folder named "dload" (I used EVA-L09C432B182 (UPDATE.APP))
Method:
1. Copy the official stock firmware .app file to your SDCard inside a folder named "dload".
2. Remove SDCard & Sim Card from the phone.
3. Put your phone in to Fastboot (Turn off phone, hold volume(down), insert usb cable).
4. Load DC-Phoenix and select Fastboot mode.
5. Click "IMG Files" tab and locate the .dgtks file using the "Config or recovery file:" field.
6. DO NOT uncheck the boxes next to "Not erase NV" and "Not erase oeminfo" as this will delete your IMEI and other information completely.
7. Click UPDATE and wait for it to fully finish (you may see an error regarding FBlocks but it should still go on to complete).
8. Once you see it is completed, disconnect phone from PC and restart the phone by holding the power button.
9. This should load you in to a very basic firmware (it may take one or two reboots to achieve this).
10. Insert your SDCard with the newer, official, stock firmware that you want on the phone in to the SDCard slot WITHOUT SimCard.
11. On your phone home you should see an icon named "Upgrade" or "Upgrade/Update Phone" on the first page. (I've forgotten the exact name of the icon but it will be obvious to you).
12. Click that icon and it should go ahead and install the firmware .app on to the phone off your SDCard.
After following the on screen instructions you should now be back to stock firmware. I recommend re-locking your bootloader now using fastboot and your unlock key if you are trying to do so. If you go on to update to Nougat 7.0 before locking your bootloader back up you won't be able to do so without downgrading back to the same firmware that was on your phone when you originally unlocked it.)
Hope this helps somebody who is stuck and exhausted every other avenue with nothing left to lose.

I had a similar issue after doing this :- unlock bootloader...root MM....Upgrade to Nougat...root...Rollback to MM...root...Upgrade to Nougat.. borked!!!
I was left with a phone that only booted to bootloader and no recovery or possibility of flashing with dload worked.
Luckily DC Phoenix got it into a usable state where i could enter erecovery and flash Nougat again. Seems the backdoor method they use to load the OS, at least at a low level, is very effective!
There's probably a lesson here, but I've never had a phone so easily bricked....
Thanks :good:
Peace

Dear DCStreamer,
I tried to follow your procedures with my Huawei tablet but don't work: where I wrong?
I have a Huawei P9(L19-C636). I had decided to root my phone and install custom roms etc. However in the process, it failed and i messed up my firmware. Then, all I wanted to do is restore it back to stock. I have tried to force flash the C636 firmware with no success. Then I was told to flash the rollback package first. I flashed the rollback package. However, it messed up my phone and now I cant even boot into the force flash menu. I've been trying for so long. I can only boot into fastboot menu. I cant even flash anything in the fastboot menu as it is locked. Please help. I'm at the verge of losing hope

I successfully managed to follow the guide until step 6a. However, I cannot boot into the recovery after that. I think the problem is, my phone's battery is drained completely. Charging it the whole night did not make a difference because it was stuck in the "Your device is booting screen". Even when I force shut down my phone, for some reason it boots back up. I am not sure what I should do
Do you have an unlock code?

Sorry for the late reply. Was away from town. I have obtained the unlock code and unlocked my bootloader. Yes i can access the force update screen.
When trying to restore my phone through this method(https://forum.xda-developers.com/showpost.php?p=74169408&postcount=7) , i succeed till step 7. When flashing the rollback package, it loads untill 99% and then fails. I am not sure what to do.

Look at my description:
Use the Rollback_Package_EVA-L09_to_EMUI4.1_Android6.0_C900B300.zip to rollback your phone there are instructions inside the zip file.
After this use the B136_full_update.zip the same way.

I Have a L19-C636 Which package should i flash?
Hello guys, I have a big problem.
I was restoring a TWRP backup, something went wrong and now I have a soft locked phone.
When powered up, it shows the Huawei logo and goes straight into eRecovery Mode, where I have 3 options: downdload latest version and continue (it obviously fails), reboot and shutdown.
Vol + and power don't trigger TWRP (I'm fairly sure it was overwritten by the stock recovery)
Pressing Vol - and connecting USB I can enter fastboot & recovery mode (PHONE Unlocked, FRP Unlock), but every fastboot command gives me "FAILED (remote: Command not allowed)" during writing.
What can I do? I can't flash a recovery, I can't flash a zip.
When plugged in the PC in eRecovery I can hear a Windows 10 notification sound and HiSuite activates, but it doesn't recognize the phone.

Despite your bootloader shows as "unlocked", it most definitely is not; unlock it again and then you will be able to flash stuff

Now I have another problem, my backup was busted. I want to flash the latest no brand EU firmware, and flashing PRA-LX1C432B199 fullota using fastboot seems to work, but the phone gets stuck in the "your device is booting now..." phase.

First off, backup and restore procedure have been proved NOT WORKING for PRA devices unless you use haky's method which involves flashing a decrypted boot before starting, which I don't think you've done. So basically, forget about that backup (and for the next time, follow haky's method at codeofhonor.tech)
Secondly, B199 is a NON RELEASED firmware, maybe it's not even signed by Huawei, so you're taking some risks there; I would suggest flashing an older firmware and, if that doesn't work, following the restore method in the guide I told you about, with the firmware it provides.
Good luck!

I've done the "Reset via TWRP" but the backup doesn't show up in TWRP. Is it because it's a no brand firmware and mine was a branded P8?

I understood that backup / restore do not work for /data partition (may even brick), but that we can backup/restore, for example, /system. Am I right ??

I did successfully backup system, vendor and boot while decrypted, but not data. Anyway, I wasn't planning on restoring emui from twrp either, lots of chances of bricking involved.
Did anyone find a solution in this particular case? I read all forums but I didn't find the steps to fix it yet...
Situation: Huawei P9 keeps turning on and freeze at Huawei Logo. I have an option to go to fastboot mode, but unfortunately, I can't do
anything else (FRP locked). I received the unlock OEM code from official Huawei site, but I can't unlock OEM.
When I launch the fastboot OEM unlock ... command (with unlock code), I always get:
...
FAILED (remote: Command not allowed)
When I am trying to flash is the same situation: FAILED (remote: Command not allowed)
SD micro card is not booting...
The phone is not rooted.
Are any masters who could provide how to unlock bootloader or any flashing method without an unlocked bootloader in this particular situation?
15€ for dc phoenix
any other options?
I have probably the same issue, but maybe you are luckier than me.
Can you still get into the manual updater via "vol+ & vol- & power"?
If you can, you can flash it here with the stock rom app in dload folder of the sd-card.
For me however, I cannot get into the manual updater, erecovery.
I am still trying to figure out if I can get "fastboot update rom.zip" to work. It tells me the android-info.txt is missing and I have no idea where to get it, or how to make one.

So strange that nobody knows how to fix it. I spend many hours how to find a solution but still couldn't find it..
Did you try by yourself to erase FRP with DC-Unlocker?
Yes, I did. Afterwards I saw in the faq that it doesnt work for bricked phones.
Thankfully I never bricked the phone, but frankly I didn't know there were cases that even DC Phonex cannot resolve (at least to unlock bootloader for the first step)
The following guide helped many people to unbrick phones, but it relies on flashing through fastbook - requiring to have the bootloader unlocked (hence you are again with the chicken and egg problem):
http://forum.xda-developers.com/showpost.php?p=74169408&postcount=7
There is also another commercial 'repeair' tool that was spoken on XDA Huawei topics about, but now looking carefully, seems it's not for unlcking bootloader and neither for unbricking (?!) - you can double-check if you find anything useful:
https://hcu-client.com/
Sorry it doesn't help you...!
The fastboot flash commands are locked due to the frp-lock.
I talked to the tech-guy from dc-unlocker and he said the frp-unlock from the tool only removes the associated google account in the OS, but does not change the frp-lock.
This however might work: https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
But I'm thinking of returning the phone for repair because it is only a week old and still in waranty.
If somebody tries it, I will be glad to hear how it turned out.
Have you tried wiping everything (data/cache) by using the stock recovery? Volume up and the power button should do it. Then check if it will boot after doing those steps.

For me:
-Bought the phone with android 6.0, Bluetooth was working.
-Upgraded to android nougat with the normal updater (in running OS).
-Upgrade was succesfull but bluetooth was not working.
-Set factory defaults, bluetooth still not working.
-Downloaded stock rom android 7.0 and installed it using dload method (using manual updater (vol+ & vol- & power).
-Was succesfull but still no bluetooth.
-Reverted to android 6.0 using the rollback package and a stock rom I downloaded (using manual updater)
-Revert was succesfull, adroid 6.0 was running and bluetooth was working.
-Wanted to try updating to android 7.0 once again using the normal updater.
-Normal updater said it was already at latest version, but it was android 6.0 (???)
-Tried updating to android 7.0 (same package as before) using dload method (manual updater)
-Updater stopped at 5% and said wrong package (weird, it worked before)
-Tried using the same rollback package as before to get it to region c900 (worldwide)
-Went to 100%, rebooted and stuck at boot-logo.
-After a while, rebooted my phone, but always stuck at boot-logo.
-No longer can shut down my phone. Holding power reboots.
-Tried getting to erecovery using vol+ & power. Reboots to boot-logo (vibrates twice during reboot)
-Tried getting to manual updater using vol+ & vol- & power. Reboots to boot-logo (vibrates twice during reboot)
-Can get into fastboot mode, but bootloader andr frp are locked. (Limited fastboot commands).
-Letting power drain shows red power circle indicating the battery is practically empty and will only boot to fastboot mode (plugged in)
-After charging still stuck at boot-logo.
I think that is about it...
Thanks for the help

Any luck in doing a rollback again? I mean, wouldn't hurt to try doing it again. I also wonder why doing steps the second time gives us different results. Weird.
Well, I sort of tried it but it only works from the manual updater, which is not accessible.
So, I bit the bullet and tried dc-phoenix flasher. (https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial)
-Loaded nougat in dc-phoenix. Started flashing using the "backdoor".
-In the end there was something that failed, but it did managed to write back the erecovery and manual updater. (I pressume it would not have failed if I had chosen the marshmallow image)
-So at this point, I still had no OS.
-I tried using the manual updater to go to nougat but that did not work.
-I tried the marshmallow package with the manual updater and this did worked.
-So I had a working marshmallow. (with bluetooth working)
-and NOW the first thing I did was OEM UNLOCK!!!!!!
-Flashed TWRP and installed nougat with TWRP.
-The flashing procedure was a partial succes. Nougat was running but without a keyboard installed for some reason.
-Installed a play store keyboard so I can actually type the password of my wifi
-But still no bluetooth in Nougat.
-This evening I am going to try a package via the firmware finder. (The nougat I was trying is b384)

-Installed a play store keyboard so I can actually type the password of my wifi
-But still no bluetooth in Nougat.
-This evening I am going to try a package via the firmware finder. (The nougat I was trying is b384)

That happened to me one, not having a keyboard to use. I think you have to flash the public zip that comes with the full package.
Since you're unlocked and have the whole package, I suggest that you do the HWOTA steps then. The post title should be about the nocheck recovery thingy.
I got it sorted yesterday.
Got 3 zips with the firmware finder and installed those through twrp.
Bluetooth working and everything
I'm still on b386 though. I tried 397 and 393 which the firmware finder said where compatible (imei check), but they both failed to install through twrp.
And then I got tired of it, so I stuck with b386.
Thank you all for the assistance!

I'm not sure if it's the same for the other versions (L-XX) but for my P9 (L19C363), installing the B394 gave me "dynamic photos" in the Camera app (live photos in iOS) and searching for photos by date, album, etc. in the Gallery app. If what they say is true, that the bootloader being unlocked doesn't affect being able to install updates, I suggest that you flash the stock recovery and update through it if want to get those features
