4. accept fastboot unlock
5. And then it magicaly booted into twrp (my phone's fastboot was unlocked before)

hello, i'm using Huawei P9 Lite VNS-L21. i tried to flash the stock nougat Firmware Which i actually did and it worked flawless! but there was a little problem because there wasn't any Software update option in there, so after that i wanted to downgrade to stock MM.

[UDPATE] What to do after Board Software IDT Flash [SOLVED]

I have bricked my M3, and was successfully revive it using IDT board software. And now i stuck at the old ROM
I was trying to upgrade using SD Card method with many dload file but no one success
Please help me to figure it out, thank you
=====================================================
As I mention before , i was sucessfully flashing board software which bring me to basic firmware.
I try to update using USB OTG and SD Card but I got no luck.
Then I use fastboot to flash this firmware [HUAWEI MEDIAPAD M3 8 FIRMWARE (BTV-DL09 ,C100B009, EMUI4.1+ANDROID 6.0) [ANDROIDHOST.RU].RAR]
Extracting UPDATE.APP and take out boot, recovery, cust, and system then using fastboot to force flash
* Reboot into fastboot by pressing vol down button (phone off) while connect USB
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img
This method bring me to EMUI 4.1 on Android 6.0 as mention above
But i have some problem here :
* My SIM got locked
* I cannot update to EMUI 5/ Android 7
What I was done :
+ copy file UPDATE.APP of EMUI 5 to dload folder than update via USB OTG. I use this file [BTV-DL09C683B352CUSTC683D001 FIRMWARE ANDROID 7.0 EMUI 5.0 05014EAR.ZIP]. But I got messaege "No update file found"
+ Exctract boot, recovery, and system from update.zip and cust.img from update_data_full_hw_eu.zip then flashing using fastboot . But it end with bootloop
+ Flashing update.zip via TWRP. It was success but failed to grab EMUI info or firmware version. It show NRD90M test-keys on it. TWRP red log
Failed to mount ........ (forgot what was failed, only remember there were 2 invalid argument) (invalid argument)
Please anyone give me a clue to update my M3 to newer version.
Target : move into M3-BTV-DL09C100B307 or M3-BTV-DL09C100B311
PS: I have M3-BTV-DL09C100B307 file (update and update_data_full_hw_eu)
I also have M3-BTV-DL09C100B311 file (update.zip, update_data_full_public.zip and update_full_BTV-DL09_hw_eu.zip)
Thank you

Update.app should match your device in order to be able to flash it via dload method. As I can see your device it's not properly updated to EMUI 4.x Android 6
