Request - Could Someone Help Me Modify TWRP for my device?

There are two working TWRP custom recoveries for my Lenovo A7-30 A3300 tablet, with versions v2.8.2.0 and v2.8.7.0.
The only issue in v2.8.2.0 is that the CPU temperature indicator only shows 0 C.
On the other hand, the version's language is Russian and I cannot change it (builder is probably Russian). /system only shows the bin folder, the other files are not there, even if the system partition is mounted. Also, the splash screen is changed.
Could someone help me so that the language can be changed to English, revert the splash screen, and make the system partition accessible? Thank you so much!
