Huawei P9 stuck in bootloop TWRP doesnt work properly and EMUI recovery doesnt aswell - General Questions and Answers

Hey guys, I'm new to this board bc I can solve my problems mostly on my own but this time... I have no clue what I'm supposed to do.
I tried using ADB and Fastboot to flash TWRP and everything worked fine. When I rebooted my phone I couldn't get into recovery and I was trying different commands to access recovery but I got "command not allowed".
Then, by accident, I typed:
-fastboot flash boot twrp.img
and since then I'm unable to boot my phone (bootloop), can't reach recovery and I have no idea what to do.
I'm always stuck in the "Your device is booting now..." screen for a few minutes, then my phone just reboots.

[Q] Xoom stuck on boot screen

The other day my WiFi Xoom stopped getting past the "Motorola Dual Core" screen.
I have removed the SD card.
Android recovery mode gives me the error android with the "!"
It does this plugged in or on battery.
Not rooted.
What else should I try?

Hadn't really done anything. Just normal use. No out of the ordinary installs. Turned it off. Next day I tried turning it on and it won't boot.
Did you ever resolve this ?? I was give one to repair for a child and it too is stuck on the red boot screen. The good thing is the person who sold it to them was a hacker and put TWRP on it of all things. I was floored when I tried to enter recovery and found teamwin.
but the problem is its still stuck on the boot screen, i did flash it 3-4 times with M604 M602 flashes and some other customs but nothing works, it completes flashing and wiping caches but always goes back to stuck on boot screen..
perhaps I have to unclock the bootloader or something for the flash to be succesfull ?
Just wanted to say I fixed it with these commands and firmware if anyone is interested. I tried everything else including flashing with twrp and wiping all caches and it didn't work, getting the stock firmware and doing it like this worked to clear boot screen endless stuck
download fastboot and adb and xoom drivers 6.4 (about 5mb) and the appropriate stock firmware. for me it was ZM604
at the command type
adb reboot bootloader
you may need to unplug and replug cable after it goes in fastboot mode.
fastboot devices
.. should return something "02a439cj0skjdke fastboot" to proceed.
fastboot oem unlock
.. look at your tablet and follow the instructions, for me it was down twice and up once to accept unlock conditions, then it reboots
on reboot press vol down 2 seconds after you see moto logo, it will enter fastboot
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot erase userdata
fastboot reboot
no need to relock after, you will see android logo and first boot pop up after 2-3 mins

Honor 4C Fastboot Flash OK But nothing changes

Hi guys, I have an Honour 4C wich reading through forums i managed to update it to most recent AOKP 7.1.2 version (https://forum.xda-developers.com/p8lite/development/rom-t3717536) for P8Lite Alice and everything was ok.
I can recall some years ago I had to change my model from CHC-U01 to CMH-U01 to update to 6.0 if my memory is right and recently flashed P8 Lite firmware (B896) in order to flash AOKP and device was running without problems.
I was running my phone in performance governor for gaming , forgot turn it off, My phone complety run out of battery while asleep i woke up put it to charge.
It charged a little and after it powered on by itself bootlooping into OS.
I'm now facing a bootloop, phone auto turns on when charging and bootloops.
If I enter fastboot and exit into a shutdown its stays charging ok. (Just to turn on by itself at some point)
PC detects fastboot just fine and I can fastboot, however, no matter what I Flash i can't get sytem to boot up properly NOR can i boot TWRP recovery.
I flash twrp into recovery, IT says it was flashed OK but when i boot into recovery it just open that EMUI menu with reboot into system , wipe cache/ and system restore (wich takes 1sec , says system restored but it doesnt).
I've tried to flash B896_Update.zip used HuaweiUpdateExtractor and flashed BOOT RECOVERY AND SYSTEM OK , but again, no changes... it boots into AOKP Logo when it should boot into Huawei logo if any changes took efect.
If boot into fastboot and press KeyvolumeUP, other eRecovery EMUI appears now with restart , wifi update and shutdown.
When I try this Wifi method it bootloops right after it says connecting..
Also I can't do a fastboot erase (cache...userdata..any) because it gives FAILED (remote: Command not allowed) ... my bootloader is UNLOCKED and command prompt is running in administrator mode.
Same happens if i try to run fastboot boot twrp_Recovery.img , download OK but FAILED remote: Command not allowed.
I have no way to do an ADB sideload and try to go from that because system doesnt boot.
Is it just HardBricked even so I can boot into bootloader and fastboot?
It is driving me crazy it feels like fastboot just "fake flashes" or something . Nothing takes effect ....

Fastboot Flashes but dont doesn't persist.

Hi Korreya,
Once I to had ended up in a boot loop when I had messed up during twrp (that was 1st time I had tried flashing it into a phone).
I eventually tried many methods, few of which you have also mentioned, and finally succeeded but I exactly don't remember what I had did so I'm not sure if this works.
Download the stock Honor4C ROM (I'm not able to post the link so you could just Google it) and copy the file named UPDATE.APP into a folder named "dload" (without the " , if there's no such folder just create one) on your SD card and then try going into the eRecovery EMUI and updating the system.
PS: Note that this would install the official stock ROM on the device.
Try it and do let me know if that helps.
Peace

Cannot revive my phone

My note 6 pro suddenly started doing boot loop. I tried to revive it by flashing stock firmware but nothing seems to help. It has unlocked bootloader, with TWRP installed. This is what I tried:
Put phone in fastboot mode, I do see the fastboot image.
Computer recognizes the phone. 'fastboot devices' shows correct device.
Using MI Flash tool to flash 10.3.6 global fastboot image. It takes about 160 seconds to flash all the partitions. The phone will reboot at the the end of the flash. Flash tool doesn't say "successful" though. Its status is still "flashing".
No other errors. When the phone restarts, it is still stuck in the boot loop. Interesting thing is, if I press volume + button and power button, I see TWRP flash for a quick second on the screen then boot again. Looks like the recovery image wasn't flashed properly.
Looked at the logs. Nothing strange. Also tried to run 'flash-all.bat' in a command line (not sure if we are supposed to do that), but all the fastboot flash commands look OK.
Anything else I can do to revive this phone?

Question How to avoid the error touch not working when installing twrp in 2201116Si ?

I tried the twrp when i flashed it
the first command i used are in this order
fastboot devices
fastboot flash boot twrp12.img
After that i just booted into the custom recovery manually, and then the touch wasn't working did i do something wrong ?
I also got stuck into the bootloop a couple of times.
