flash this recovery.img to your phone using fastboot then lets know if you can still boot into stock recovery

if you can, you device seems to have dm_verity so custom recovery will pend for now, patch boot and root using the guide at https://www.hovatek.com/forum/thread-21427.html
then lets know if you can still boot to homescreen afterwards

After i flash that recovery.img, i still can boot to recovery, but screen is rotated 180* and text is very small:

And this is OEM device_info:

My current android version is 7.1, but this one seem be 7.0
Is there anyway to backup without TWRP?

You will need a box/dongle like cm2 or NCK to backup, do you have access to any?

the rom is probably not a perfect match but that's not even the point @x3non made.
Your phone has DM_Verity so boot must be patched before TWRP can work. Read https://www.hovatek.com/blog/dm_verity-i...-bootloop/
Here's what to do
Backup your firmware using Miracle box @ https://www.hovatek.com/forum/thread-25452.html
Patch boot using https://www.hovatek.com/forum/thread-21427.html
Flash the patched boot using Miracle box @ https://www.hovatek.com/forum/thread-26213.html
