[Help] Flash Stock Rom HONOR 6X

Hello guys, can somebody help me?
I own a Honor 6x (BLN-TL10)
When I bought at 2017, I flashed my firmware to a different one cause I didn't wanted to use the chinese version, so I upgraded or downgraded to that firmware (BLN-C900B131) since that change, my device always recognize as hi6250, and when I try to install the original firmware on my device, It fails, on the update proccess appear that message, "Software install failed! Incompatibility with current version." cause I want to upgrade to 8.0 oreo, my phone right now is at android 6.0 emui 4.1.
Can you send the link of update file that you have used? And a screenshot of build number?
I'll attach 3 screenshoots, one of my EMUI and Android at the moment and the firmware's that I tried to install
The BLN-TL10 firmware that was the same that came with my phone when I bought
I've tried to unlock the bootloader, but Huawei phones bought on china doesn't have OEM unlock option enabled ;(
Idk if have some way to unlock bootloader without that option

Downgrading from latest firmware (ASJA)

.I just want to share my experience with the firmwares (G970F).
First im not against with any updates for the phone but I accidentally press the update for the latest which is the ASJA (Philippines Carrier) and i realize it comes with a new bootloader which is S3 and the stock is U1.
Is there anything I can downgrade the bootloader so I can downgrade the complete firmware also? I want the stock firmware the first one (March 2019) because of my own preferences and I just want to stay with it. Any ways to solve this even on the near future? Glad to hear some ideas. Thanks
I have a similar question. After the recent Feb 2020 security patch update, the bootloader has been changed from 3 to 4. I so wish i had not updated. Is there anyway to go back to Android 9 which has BL 3 via Odin? Help would be appreciated, thanks.
im not sure its possible, moving from u4 to u3. the only possible solution o go back to android 9, is to find android 9 firmware with u4 security bit

Help downgrading encrypted bootloader samsung phone.

Hi all !
Hope everyone have a great day, i have got a samsung galaxy A6 US variant TMB, (SM-A600T) with android version 9, I was trying to root the phone but didn't have the knowledge that this phone can't be rooted because of locked bootloader which can't be unlock with any procedure. So i gave up and just updated my phone to the latest version available of PIE . (Android 9), To tell you more, before it was also on the same version of android 9 but earlier date. I have not updated a whole version of android but just to a latest date of android 9, Android 10 is also available for this phone but i haven't done that yet. The main problem with my phone is that before this update i just needed to charge my phone once in 24 hours, and now after update i need the same phone with same demands to charge it 3 times in 24 hours, Did every optimization for battery, unused apps, extra apps uninstalled, just one google account left, synchronization is off, NFC and near scanning is off, Bluetooth / Wifi is off, GPS is off. Auto update for apps and system software is off. Battery saving mode is enabled, clear cash has been done, factory reset is already done with flashing this version of android with odin tool, and etc every other thing has been tried with no luck, please don't advise for these things as the main problem for me is just the android version itself which i have newly flashed. Because of locked bootloader i can't flash back my older version of android 9 with odin tool, phone gives error of bootloader :
sw rev check fail device 2 binary 5​something like above after many tries the same result. tried my old firmware with the new bootloader but still no luck. (Same error). Any help or suggestions will be greatly appreciated. I am thinking what if i extract the AP of the new flashed firmware and replace the system.img.lz4 with my old firmware's system.img.lz4 to trick the phone and reflash with the new firmware but old system image file, Can this be done ? or i may brick my phone for ever ? what if i take my phone to the outside market and request a z3x flash for the old firmware version ? will that work ?
Please give any accurate solution i really want my old phone back, this locked bootloader has become a really annoying thing for me. I will never buy a phone like this which bootloader's can't be open again. Or if i wasn't able to flash this to my old version i will never use android again in my life, Better option will be to buy an iphone after 17 years of android use.
Thanks in advance.
