Bricked Huawei P9 Lite - Stuck in Boot Screen - General Questions and Answers

Hello,
as the title says... I bricked my phone. In the past, I successfully installed LineageOS on my old Galaxy S3. I got a used Huawei P9 Lite recently and wanted to install a custom ROM. Here's what happened:
1. Unlocked the phone
2. Accessed Fastboot mode
3. Installed TWRP* via fastboot flash recovery file.img
4. This didn't work and I read on the web, I could try to flash revocery2 with fastboot flash recovery2 file.img
5. This didn't help either, so I decided to cancel my plan and use the manufactorer's system since the system still booted (of course, I didn't install any custom OS).
6. The phone told me on each startup it's unlocked. I didn't need the unlock anymore, so I accessed the Fastboot mode again.
7. I re-locked the system by using fastboot oem relock password.
8. The phone asked me to do confirm this action and do a factory reset
9. After this, I'm stuck at the Huawei logo and can't access Fastboot mode anymore!
When I shut down the phone, it immediately restarts itself. No chance to get into Fastboot mode again, which I did through pressing Vol- and plugging in an USB cable.
*I tried several versions, 3.0.1 and 3.2.1 since no version worked
This may be a beginner's fault, my last phone was already unlocked and I had not a single problem back then. But this time... I hope you can help me.
What would happen if I let drain the battery down to 0% - the phone wouldn't restart of course. If I press Vol- and plug it in, would I come back to Fastboot mode or would it stay in this loop?
Any help is appreciated!

TWRP Recovery with Mate 8 Nougat AL-10

Update:
This was the answer: https://forum.xda-developers.com/mate-8/development/unofficial-twrp-3-0-3-0-mate-8-t3524025. I'm now in TWRP.
- - -
I got an AL10 as a gift the other day. I let the phone update to Nougat before I tried to root it.
I used DC unlocker to unlock the bootloader, as well as unlock FRP. However, there is no option to unlock FRP from Developer options in the Android settings.
On Linux I use adb to reboot into the bootloader. Then, I use fastboot to flash the latest TWRP image (3.0.2.0).
That's where the problems start. Once TWRP is flashed, I try to reboot the device and into TWRP.
Nothing happens if I press volume up + power. I've also tried volume down + power, and doing this without the USB cable attached. I've tried letting go of volume up and power when the screen flashes on, and holding it down.
It seems one of the three things happens:
1. I get stuck at a phone is unlocked and can't be trusted, device is booting now, and then Android boots as normal.
2. I get stuck at device is booting now, and the device doesn't boot.
3. I end up in Huawei eRecovery.
I've also tried using fastboot to boot directly into the TWRP image, but I get a failed error.
Any insights or advice? I'd like to run Linux Deploy on this phone, which requires root.
Many thanks in advance.

[Resolved] HT16 Stuck In Bootloop

Hi! I'm kind of new to this so please forgive me (done once before with a few problems).
Basically, I was looking to root my new HomTom HT16 with SuperSU by downloading a custom recovery (TWRP). I rebooted into bootloader with USB Debugging enabled and OEM Unlocking enabled too.
I selected Fastboot mode from the menu in the bootloader and plugged my phone into my computer. I had no problems recognising the device. I followed the bootloader unlocking steps with:
{fastboot oem unlock}
The instructions that I was originally followed told me that I had to use the Fastboot command (with the recovery.img being TWRP):
{fastboot flash recovery recovery.img}
I was told nowhere that I had to clear any cache partitions (still not sure if I had too). Everything I did seemed successful until I was told to take the battery out, put it back in and turn the device on. It brought up the "HOMTOM" text for the boot screen but instead of booting, it repeatedly turned off and on. Because none of this actually worked, it didn't actually flash the recovery, and so I couldn't boot to it. It just got stuck in a boot loop.
I searched up how to fix a bootloop and I could find anywhere a solid solution unless I just wasn't looking properly. I have all the factory ROM files, I just don't know how to use them to replace anything that could be corrupted. I flashed back the original recovery.img but it still will not turn on, it just says on the "HOMTOM" text screen for a very long time. The recovery also doesn't work, it's just an image of broken android with its internals showing.
Does anyone know what to do now?

Do you say you have the original files if yes, then if your device is a Mediatek device use SP Flash Tool to flash the rom. If you still need help contact me here or on [email protected]

i bricked my honor, is there anything i can do?

So I had an unlocked H8 with LOS. As I wanted to install EMUI, I put the proper restore Update.app into the dload folder and started Huawei's recovery. Everything went well, I formated data and wanted to install the EMUI 4.1 ROM using the same method.
Unfortunately my H8 is bootlooping and there is now way into erecovery nor any other recovery. It simply reboots on every single known vol up or down key pressing combination. The only thing I can go to is fastboot mode when holding down vol down and plugging in usb wire. But, it says frd locked and I can't install nor boot twrp. It's simply gone and reboots all the time.
Any hints? I can't even turn it off.
I wanted to give away that phone that's the reason. Last time I did it this way, I could flash the EMUI 4.1 since it's signed. But not this time.
Interesting part is, that although fastboot says frd locked, I still get the "phone unlocked" warning on every reboot. dload method isn't working, as it simply keeps rebooting.
It's my hardest brick so far I ever encountered
the same thing happened to me.....on my phone lock/unlocked frp and bootloader were tweaked for some reason(I mean that what was written wasn't the reality) so how did I fix it? I kept on to flash rollback package many times and I tried to unlock/relock bootloader again, at the end the phone let me to flash the firmware, I didn't know how but the phone allowed me to flash things throw recovery(using dload method). At the begin I only could access to erecovery and fastboot. I suppose that I broke system and data partition and while I looked/unlocked the bootloader, the wipe fixed the partition table. Sorry I'm tired and I know that my English sucks, I hope you understand what I have written.
How did you enter erecovery as this isn't working for me.... What did you flash over fastboot?
Have you tried flashing the firmware separately using adb on computer?
For this you just need to extract the Update.app using the firmware extractor for huawei. Then flash them individually using adb commands in cmd.
I can't access any state that would allow to do adb.

sorry. I'll try to explain better, however on Huawei/honor devices there are not one but two recoveries, so one is the normal recovery flashed in recovery partition, the second one is the Huawei recovery that is flashed in recovery2 partition, so if you didn't touch recovery2 partition, your erecovery is still there, now, if you press VOL+ VOL- and POWER it will reboot to recovery2 and it starts to flash something from dload in your sd card, so in my opinion you should do this things, first try this method to flash rollback package(this is the transition package from 7 to 6 and you will find it on honor site) if this is still not working try locking and unlocking again your bootloader(I hope this fix partitions of your device) then try to enter recovery and do a wipe and then boot your device, if this doesn't work flash rollback package(now it would work) and then flash an emui 4 full firmware image, always using dload method. trust me... I did the same... and it worked for me. let me know if it works for you :good:

I ran into this issue not that long ago. What you have to do is relock your bootloader using ADB. The ADB commands and instructions can be found in this thread.
Just a FYI, do not use the links to the software listed in that thread as it is a little outdated. The method still works but the software will probably not work. Just be sure to get the most recent/appropriate version of SuperSU and TWRP via their official threads (This is if you want to re-root). There are Honor 8 specific TWRP files if I remember correctly, so be sure to check around the Honor 8 forums for the correct files.
A quick summary of what I did:
1) Power your phone off and then boot into fastboot by holding Vol down + Power; as soon as it boots up, plug your phone into your combuter via your usb cord.
2) With ADB running, type:
Code:
fastboot oem relock [COLOR="LightBlue"]################[/COLOR]
NOTE: The '#' should be replaced with your unique unlock code that you obtained to unlock your bootloader.
3) Wait for it to format and reset your phone and go through the setup. BE SURE TO BYPASS all google registration; skip everything you can to get into the phone itself. If you do register, it will reactivate FRP and you'll have to start over again.
4) Turn on USB Debugging and every other setting that enables developer administrative navigation and control just to be safe. USB Debugging being the most important one, though.
5) Restart your phone and boot into fastboot again using Vol down + Power.
6) Unlock your phone again with:
Code:
fastboot oem unlock [COLOR="LightBlue"]################[/COLOR]
7) Once the command is entered, it'll reset your phone once more and - as stated before - bypass/skip all google (FRP) registration.
8) Enable developer options and USB debugging again and make sure that OEM Unlocked is checked and grayed out.
9) Reboot into fastboot mode to confirm that FRP is disabled and you should be able to install TWRP now via ADB.
@Numerics thanks. The thing is, that I can't boot anything. I can't even go into eRecovery. Nor can I flash a stock EMUI 4.1. It just boot loops all the time and I can only access fastboot.
If you can flash twrp..........Install los or other Rom ..................Go back to stock.......you must flash b360 ober adb...... because los is 7.1...............if you on b360 you can usw the rollback for emui 4.1........,..............sry for bad english
I can easily go to fastboot. But I can't flash anything. I extracted the img from the update.app but can't flash. It simply says that it's not permitted.

With my method, you don't need to flash anything. Just relock your bootloader via adb in fastboot mode and let it reset. Unless I'm not understanding your issue entirely.
@Numerics as I said, in won't boot anything as it is constantly boot looping. There is no way to access any kind of recovery nor erecovery. There is no boot into Android. The only thing accessible right now is fast boot (which is not ADB). But even in fast boot I can't do anything als operations are not permitted.
after boot looping and starting fast boot mode, I can see a "Android reboot reason" section saying:
AP_S_PANIC
data is invalid
There is still a lineageos installed on system as firmware but as I tried to get rid of it by going back to stock EMUI, I guess Huawei's rollback did something wrong and killed recovery (although I did it in the past successfully).
I tried to run HiSuite to recover my phone, but it just says, that my phone is not supported.
Speaking of this, Huawei messed up with that whole fastboot locking bull****.

No, I know ADB isn't Fastboot. What I'm trying to say is that you should be able to still run ADB via CMD on Windows when you're in fastboot mode to relock your bootloader with the directions I gave in my previous post. It'll force-restore your phone to a non-bricked/vanilla state. At least that is how I fixed mine.
Like... You can't even try using the 'fastboot oem relock ################' function via the ADB console while in fastboot?
yes boy trust us, you haven't a working OS so it is a normal thing that your phone reboot, you cannot access to recovery because some partitions are corrupted (data partition) , so these are the steps that could help you:
1) using fastboot, relock your boot loader
2)using fastboot, unlock your boot loader (partition table would be ok now, and you would be able to use load method to flash things trow stock recovery)
4)put inside your sd card \dload\update.app(use rollback package)
3) press all the buttons while your device is rebooting(do this before the blue screen logo appear), your phone is now looking for something inside your sd card
5) if the next step doesn't work do a factory reset from recovery that now would be working
6) put inside your sd card a full android 6 (emus 4) update.app and pressing all buttons it will install the firmware
7) your device now is locked and back to stock, maybe without cust partition or maybe in test mode but it is certainly alive
8) do a factory reset and reinstall the firmware
9) your phone is now ok
You don't lock the bootloader via ADB but via fastboot.
As I said, northing was restored and nothing is booting and I can't unlock my bootloader again. As I said, recovery is not working so the file in dload is not loaded and used. Which is strange.
Locking bootloader didn't do anything besides locking the bootloader. Device is still dead and I still can only access fastboot.

This is not the truth.....locking bootloader will erase all your data and fix partitions....and with fixed partition you can access to recovery ......trust me the only thing that you can do is to lock your bootloader......you can't flash anything from fastboot and boot recovery or system now...... lock your bootloader and then unlock it again, try using "fastboot OEM lock *****" or "fastboot OEM relock *******" (try cmd runned as admin, people say that this makes the difference) then unlock your device again and .....magic your recovery will boot......the same thing happened to me and I fixed my phone using this trick, however, even if you had frp unlocked it would say you that isn't possible to write anything because you broke some partition, and that's the reason why you can't boot recovery, wait one second and think: why doesn't my recovery boot?
It has nothing to do with trust. I did it and device is still a full stone brick. Nothing changed by locking the bootloader besides that now I can't unlock the bootloader anymore.

OP7 pro Android 10 stuck at bootloop

Updated my OP7 pro to android 10 few days ago.
Yesterday, I turned off my device. But now when I’m trying to turn it on, it stuck in bootloop.
I tried clearing cache from recovery mode, it’s still In bootloop.
Devices is non rooted & bootloader is locked.
If any other solution except wiping data. Please let me know.
Update :- Tried "Reset System Settings"
"wipe cache"
"Erase Everything(music, pics, etc)"
all 3 options from recovery mode, still it's not turning on. Seems like software damaged. Any way to flash stock firmware on locked bootloader?
Can you turn the device off? If yes, when powered off, boot into qualcomm download mode and use MSM Download Tool to restore the device:
''With the device powered off, hold Volume Up & Volume Down buttons to force it to boot to Qualcomm download mode.''
Right after the step above, plug the usb cable in.
You can download the tool here. Make sure you download the correct one:

Yes, there is. It does require having fastboot setup, and having at least a basic knowledge of how to use fastboot: https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424
Or I think you can try to switch slots A/B and see if it can boot off the currently inactive slot. Again, this requires at least a bit of working knowledge of fastboot commands:
fastboot set_active b
(or active a, depending on which slot is currently active)

Entering TWRP instead of Recovery Mode (Doogee S60)

Hi There!
I'm exeriencing a wierd problem:
On my rooted Doogee S60, i was able to enter the built in recovery mode (and from there the fastboot mode) with Vol+ and Power.
Since i've installed a twrp recovery.img, pressing Vol+ and Power will launch the TWRP UI (wich i cant use, because my touchscreen is disabled).
Normal boot won't work eighter - i flashed a corrupted system.img file as it looks like (ooops). There is also the message at the Boot Screen saying:
"Orange State - Your device has been unlocked and can't be trusted. Your device will boot in 5 seconds"
... although these 5 seconds won't countdown and the device won't boot.
If i enter the TWRP, i can still access the ADB mode. So i can sideload stuff on the device, even the sd card is shown on pc. But the command
adb reboot fastloader
will reboot the phone, but not load the fastloader/fastboot - as it stucks at boot screen (orange state).
Any other ideas to access fastboot, due to flash the recovery.img again with the original to fix?
... or simple question: did i brick it?
thx in advance
Command
Code:
adb reboot fastloader
doesn't exist.

Hi introjoe,
Are you doing? i have the doogee s60 but i just cant root it :'( can you tell me please how did you do it, or the files you use for it? i allready tried but, when i reset and enter fastboot mode, my pc simply dont recognize it.
I want to upgrade the android system to 9 or 10, thats why im doing all o this.
Thanks in advance.
@doryan666
i wasnt able to root the device in the end unfortunately.
i tried using an unofficial twrp, but i was stuck at the main boot screen
i t seems to need some bootloader-activation-code to enter the bootloader to install a new os.
the command line would look like
adb reboot bootloader "CODE"
the activation code has not been released yet by doogee ... and most probably never will be.
sorry to say but i dont think android upgrad will be possible with this device
