Unable to enter bootloader AT ALL - Huawei Mate 20 X Questions & Answers

DEAR members
So Initially everything was was working well . I used the method to unlock boot loader then flashed magisk and the latest 123 EMUI 9.1 rom
After that I flashed the magisk again
Now I am unable to enter bootloader at all . Not via the power button and volume down method and not by ADB (ADB just says waiting for device)
via hardware buttons to enter boot loader I get the following screen and phone keeps booting again about 2-3 times
Please help
Recovery via volume up button wants me download the emui 9.0 rom which I read I cannot roll back to

I did roll back from emui 9.1 .116 to 9.0

Can u detail how please ?
Thanks

From recovery

Good evening, According to funkyhuawei, Firmware 9.1.1.118 and. 123 are for the mate 20x 5g. That's probably why it crashes ...

Potential downgrade issues ( from 5.1.1 to 4.4.2 )

Hello,
Since we are all still stuck with this partially functional root on our dearly beloved SM-N7505 on 5.1.1 , i started considering downgrading it to 4.4.2 ( last version i had root fully functional on ) .
I wanted to know if there are any risks I might come across during the process and what should I do before hand
P.S : One of my friend lost his IMEI due to the downgrade on a Galaxy S3 (which was a pain on the ass to fix)
Any info are welcome, i need to know as much as possible before i proceed
Many thanks

NO bro there will be no problem to downgrade, just download rom zip file from here - http://www.sammobile.com/firmwares/database/SM-N7505/ and follow the steps :-
1. Extract (unzip) the firmware file
2. Download Odin v3.10.7 (http://dl.sammobile.com/Odin3_v3.10.7.zip)
3. Extract Odin ZIP file
4. Open Odin v3.10.7
5. Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
6. Connect phone and wait until you get a blue sign in Odin
7. Add the firmware file to AP / PDA
8. Make sure re-partition is NOT ticked
9. Click the start button, sit back and wait few minutes
congratulations you have downgraded your mobile!

no problem in downgrading from 5.1.1 to 4.4.2. but you should remember that after flashin 4.4.2, you may need to enter recovery, and wipe data + cache, or else you may face bootlogo stuck

Broken recovery , please help !

Hello everybody ! Sorry for my english and please help me ...
I manage to broken my recovery , after doing this :
( First of all I was having TWRP3.0.0 , unlocked bootloader and XOSP room)
Because of the IMEI 1 and the factory folder was broken, I use borets24 method to recover it (change it ) , from here http://forum.xda-developers.com/zenfone2/help/imei-null-asus-zenfone-2-ze551ml-t3190353/page2
I install and edit the factory folder , after that I install the service firmware WW_ZE551ML_2.2.30.1_20150417_1615_eng , I was able to put some random imei ,( because i lost the box too ) , my sim 1 is now working ...
after that I was wanting to go back to xosp room (or anny custom room) but because i was unable to flash with fastboot a custom recovery in the service firmware (is instaling but not booting in custom recovery or anny recovery ,just boot normaly )
So I install with asus flash tool WW_ZE551ML_2.20.40.139_sal358-amtech.vn.raw firmware ....but almost same problem , after a clean install , still not boot in recovery (error) ,
I already try to erase cache , same error. And after installing a custom recovery , its just reboot to bootloader .
My status : I made root with temporary recovery , and I have root acces !
I am on WW_ZE551ML_2.20.40.139_sal358-amtech.vn Room ( I don't find the last version raw file or anny )
I don't know if my boot loader is still unlocked ! ( on this room the unlock bootloader app give internet comunication error )
And of course i have broken recovery.
I try to re install over and over , to delete cache , to re install sistem , recovery ...ifwy ....img.. from same room , still nothing ...
I try to install official firmware zip , but i cant the file is too big to be flashed in boot loader ..
Now I install WIN7 , to try the unbrick method .
Any advices ?
And if somebody have , please give us a link to last firmware version ( RAW file ) .
When you have the error, did you try press power and volume up, then release volume up?

Error is wehen i try to enter in recovey ... the bootloader work ok ..
And after flashing custom recovey .... and try to enter in it , it's just restart the bootloader..
I think your bootloader is locked, when you are in bootloader, select recovery and then you have the error. Just press power then volume up then release volume up to enter recovery mode. The error message is normal.
Sorry bad english

Yes ,that works , but wehen I try to instal by adb sideload , 184 software ....its give me another error ... is loading ..and at 3 % , falied to read data ..
So , somehow I found a method to re lock bootloader ?
How to see if the bootloader is locked or not ?
When you adb sideload, did you flash with the same sku(recovery WW and firmware WW too)? Maybe try an older firmware. I read that .raw can relock bootloader but i didn't test. The splash screen is black or white?

It's black , but in the past wehen i unlocked the boot loader i flash black splash screen ....
Now i manage to install 184 WW , I'm on 58%
Maybe the raw , was relocked the boot loader .. if the 184 wil bee ok , i will try to see if the unlock bootloader app worcks .. because on this older version , give the internet eroor in app ..
The unlock bootloader app works for me. Good luck.
Done , I install the 184 WW firmware ..but the same thing in unlock app : " An unknown error occurs , wich may be a network coneection issue , please try again later " May be because of the imei 1 ( not original ) ?
The other options to unlock bootloader are availible on this version of software ?
Do you have a sim card in your device? I never tried other method but i think it will work.
Yes I have a sim card.. and all worck...

My Vibe P1 runs stock marshmellow. I wanted to install the RR Custom rom, which requires the TWRP to be flashed.
I followed the steps mentioned in https://forum.xda-developers.com/vibe-p1/development/qpst-flashing-vibeui-3-1-s272-rom-t3386650 .
so far, i have unlocked the bootloader, but still stuck with the lenovo recovery. can somone guide me as to how to proceed so I can get TWRP ?
There is another thread, which links to a turkish site, but it has no download links and the screenshots cant be expanded, so even that was a dead end......

I found it quite tricky after flashing TWRP you have to hold Volume up and down together while the phone is booting but I must of kept timing it wrong and kept getting Lenovo recovery till in the end when flashing TWRP finnished I turned phone off by holding the power button then powered on and holded Vol up + down and it entered TWRP enabling me to root.

Realme 3 RMX1821 Bricked

Hello all,
Hope that everyone will be safe and healthy.
I have bricked my Realme 3 RMX1821 and would be grateful for any help to get it working back again.
Event Summary: I unlocked its bootloader with the help of Realme Tool and then installed TWRP recovery and Magisk. All worked fine. Later on due to some reasons I uninstalled Magisk and then attempted to Lock the bootloader with TWRP installed.
Immediately after the bootloader was locked my phone was rebooted and a warning screen appeared saying “Charging Overtime”. Now I tried to turn off the phone and restarted it with Volume Down button pressed. Still the same screen with an additional message in the corner saying “Recovery Mode”. Under both the cases no other button works and I have to power it off.
Support centers are all closed due to current virus issues and I need this phone really badly.
Will be grateful if someone may help me out.
Thanks!
