BOOT problem

99% SOLVED
Hello all.
EDIT 070117 Partially SOLVED - after 0% battery is possible enter to FastBoot, but problem with TWRP or Unbrick stay...
EDIT 2 only Revolution recovery is going, but no efect... still trying install OS
I tried install Revolution ROM on my Huawei P9 lite (1 SIM card model for Europe - LN21), I unlocked BOOTloader, flash recoveries and ROMs, but after last install phone reboot ONLY in "wait for boot" mode... No acces to recoveries and FASTBOOT mode.....
Any ideas?
Thanks..
EDIT 10 01 2017
After about 100 reflashing everything inside OS works only 1 solution (99%) - i was on broke Nougat, nothing work correctly....
go to fastboot (turn off, hold down volume and plug USB - PC)
1. flash twrp beta 9 from BadWolf
2. Flash this zip http://forum.xda-developers.com/atta...1&d=1481994704
IN CASE OF UNABLE MOUNT ANY PARTITION - USE product v_3 (twrp restore by Badwolf)....
3. Put the MM UPDATE.APP in the DLOAD folder on EXTERNAL SDCARD (it is possible use internal storage, i used VNS-L21XXXXX120)
4. Install it using the 3 button method (dload method) but sometimes work only + volume and power on
5. Factory reset
In case - decryption code need, only write anything and ask on revert data by eRecovery....
Now everything works correctly , ONLY FASTBOOT DONT WORK yet....
PS SORRY for terrible english!
6. DONE!!

Unable to get into recovery mode ( rooting help )

Hello guys,
I have successfully unlocked bootloader of Nokia 8 (TA-1004), and flashed latest TWRP image via fastboot command but now i'm totally disappointed after trying many keys combos to get into recovery.
I have few questions now
1. Does still my device have twrp installed after rebooting to it system ?? ( I have to flash again and find out a way to get recovery )
2. Or Which prerooted boot image have to flash as i have security patch level of OCTOBER & Fon model number is TA1004 ( if prerooted patched image doesn't boot then what would happen i mean where to get rescue files ?? )
Please help me to get root access ( sorry for bad english )

My device detalis .. build number also visible

You might want to try to enable USB debugging, connect your phone to your PC and calling "adb reboot recovery" to verify that it works at all.
The only hardware based solution to enter recovery that works reliable for me is to turn the device off and insert the USB cable while holding the volume up key.
That way I can enter TWRP just fine (TA-1004, Oct Patch, Nirvana Kernel image).

Xiaomi MI A2, is stuck in bootloop

Hi Guys,
My MI-A2 is stuck in bootloop ( When I turn on my phone it shows its Android One logo and then it shutdown itself ).
In my phone, I didn't turn on any USB Debugging or and OEM unlocking. and now it is possible as the phone is not starting.
I am able to access fastboot and recovery options
I tried to do factoryReset the device from the recovery option but it is just wiping the data.
here are the following things which I have tried with fastboot.
- I tried to unlock the fastboot with MiFlashUnlock but it stops at 99% and gives me the error of unable to verify the device,
- flashing the Stock ROM isn't working with MiFlashTool. giving random errors.
- tried changing the drive partition. it gives error to unlock the device first.
- tried tried to flash TWRP but it also gives me the error of unlocking the device first.
Almost every command of Fastboot is giving me some kind of error
But I am able to access the ADB Sideload from the recovery option.
- I tried to load the April OTA update from ADB Sidelode. The update is Successfully installed. But the device is still in bootloop.
Saving User data is not my priority. I just want the device to be working anyhow. As per my assumption, Fastboot is not an option for me unless it unlocked. I think something from the ADB sideload can be done.
Any help will be appreciated.

Is it a Guide?
Oh, now, its a Great News!
Please delete this post from this forum.
As I have already wrote to you, questions should go to "Questions and Answers" forum.
And as I have already wrote to you, Search works here, and if you've used it, you'd get answers (in mentioned above forum):
1. MiA2 having A/B slots architecture, - is supposed to recover to the other slot X when OTA corrupts ROM is slot Y, - after numerous boot attempts.
2. In case you have tampered phone with try-and-see operations without knowing what you were doing - the only way to recover phone is: TEST Point / EDL. Search these keywords in this forum for appropriate Guide.

try the "fastboot continue" command

you need to flash the phone in edl mode
**just be careful there is a timeout ..when you put it into edl you need miflash and rom.loaded
*** download a stock fastboot stable pie for jasmine
**** unzip amd select revelant xml from within miflash
*****on phone manually boot to fastboot mode with buttons
****** run command "fastboot oem.edl"
*******device will boot to black screen ... immediately go to miflash and press the button to start flashing
___BE CAREFUL__ select clear all tick box at bottom of miflash screen
this should be enough to rescue your device regardless of what you've done or whether you unlocked bootloader or not

Help me someone!

You give problem because your'Mg3 not yet uninstall root complete, so Android system prevent it booting.
=> Solution:
- Step 1: re-unbrick your phone with unbrick tool (eu).
- Step 2: reboot to bootloader.
- Step 3: fastboot oem nubia_unlock NUBIA_NX629J
- Step 4: use volumn up or down to choose line with content "unlock bootloader". Then wait for your phone working. => Done

How to solve custom recovery not installed after flash on all smartphones[Tutorial]

Hello . A few minutes ago, I had a problem with the TWRP flashing on my huawei p8 gra-ul00 phone .the adb has command's the twrp is complety flashed on my phone , but it did not come up on my phone(after pressing vol+ and power button's the phone will automatiocally go to huawei erecovery). But I took a little initiative and came up with a solution to this problem. I'm share this.
NOTICE : IF YOU HAVEN'T A USB DATA CABLE , PLEASE BUY IT , OTHERWISE CONTINUING THE STEPS WILL NOT SOLVE YOUR PROBLEM .
Before completing all the steps, connect the phone to the computer using data usb cable, then try to enter the recovery mode (for Huawei phones, hold the power button simultaneously with the volume down button for at least one minute.) If the phone Entered custom recovery, no need to do other steps.
1_First Of All , Unlock the bootloader , then reboot the phone
2_Download the custom recovery . IF YOU HAVE ISN'T A CUSTOM RECOVERY FOR YOUR PHONE , PLEASE SEND A COMMENT AND ENTER YOU PHONE MODEL AND A NAME OF THE CUSTOM RECOVERY YOU WANT TO USE TO IT. IM WILL SEND A REGUESTED CUSTOM RECOVERY FOR YOU IN LESS THAN A HOUR .
3_connect the phone to computer and Enable USB Debugging from Developer Options(go to settings>about phone , then 7 times tap on build number , then go back to settings and select developer options , search for "USB Debugging" Option and enable it.)
4_, install the adb and fastboot drivers(such as minimal adb and fastboot) then install the phone drivers . after installing drivers , reboot the computer , then open cmd and enter the command : adb reboot recovery
5_if a window showed on phone(such as allow usb debugging) , click on yes and retry the level 4 again
If you have any questions or problems , commend here.

Hy Bysoft!
I'm new in XDA but i alredy flash some devices with TWRP, it seems that something went wrong with the installation of twrp. Did you try to boot into bootloader (adb reboot bootloader) and then flash the TWRP image with fastboot (fastboot flash recovery twrp.img) and then type fastboot reboot?
I find that list of command: adb reboot etc.. in your device page of TWRP (https://twrp.me/huawei/huaweip8.html). In this site you find the TWRP image for your device, you have to use this image when you flash with fastboot (fastboot flash recovery twrp.img where twrp.img is the image that you downloaded in TWRP site).
