[SOLVED] Bootloader and twrp issues - Honor 9 Questions & Answers

Hi there,
New here so thanks in advance for any help you guys could provide.
I need to root my Honor 9 for Android Development purposes so I tried to unlock the bootloader to install a TWRP.
(following this thread : https://forum.xda-developers.com/honor-9/how-to/how-to-root-honor-9-stf-l09c432b360a-t3778110)
When it comes to the "adb reboot recovery_ramdisk", it loads to that error message :
Error Mode
Attention!
Please update system again
Error!
Func no: 11 recovery image
Error no: 2 (load failed!)
Any clues of what i'm doing wrong and how I can get rid of that error message...?
(The goral is to root the phone using that Magisk thing everyone's talking about )
Thanks a lot!

Hi Oslo83!
Yup, still need help. I don't understand what i'have done wrong :/

Phone is still booting in normal mode ?
You got this error screen only when bootinng to recovery ?
Do you still have access ro bootloader ?

phone is still booting, no probs with that, and I still have access to bootloader yup.
i get the error message when i boot into recovery with adb reboot recovery_ramdisk
if i boot into nrecovery by pressing the buttons, i have the default honor recovery appearing.

What firmware version and region are you on ?
8.0.0.xxx (Cyyy) ?
Recovery mode is 'recovery_ramdisk'...
You should boot in twrp 0.3 when booting into recovery, as you flashed it, if you typed the right command...
recovery and erecovery are 2 differents mode on differents partition.

Version : 8.0.0.364
Region: C432
Well, as i said, i followed the thread step by step and yet, still no twrp.
Thing is, if I want to flash it again with adb (in case of something went wrong during flash?), well, i get a "FAILED" error

---

it wont flash with adb, but with fastboot it will...
I really think you messed the command you previously typed. Can you post them ?
You'll have to
Code:
fastboot flash recovery_ramdisk stf-twrp-zxz-0.3.img
again then to boot to recovery mode.

well, first, i connect the phone with usb debug and OEM enabled.
i do
Code:
adb reboot bootloader
wich give me the "fastboot&rescue mode" with phone unlocked and FRP unlock in red
then i do
Code:
fastboot flash recovery_ramdisk stf-twrp-zxz-0.3.img
and it tells me :
Code:
target didn't report max-dowload-size
sending 'recovery_ramdisk' (0KB)...
FAILED (command write failed 'No error))
finished. total time : 0.016s

You're stf-twrp-zxz-0.3.img is wrong or not i' your working folder. Download it again.

Oh! it worked!
Problem apparently wasn't the .img but the "Minimal adb and fastboot"
I downloaded sdk platform tools on my home personnal computer and managed to install twrp (plus, buttons and flash work correctly, yay!)
So, problem solved i guess.
Thanks a lot for your time, Oslo!

---

I'm using Minimal adb and fastboot without any problem.
