Help me find the firmware of this tablet A33

[Android Central Question]

Hi, my Chinese tablet is bricked and I can't find its firmware. I've already scanned the entire internet and I can't find the firmware. The tablet data is:

- MODEL : Kin7
- PROCESSOR TYPE - QuadCore A33
- MANUFACTURER : Nage
- VERSION : 4.4.2
- PRODUCT NAME : astar_mq88HD
- DISPLAY ID : astar_mq88HD-eng 4.4.2 KVT49L 20180130 test-keys
- BOARD : exdroid
- PLATFORM : polaris
- BUILD ID : KVT49L
- BUILD VERSION : 20180130
- PDA : 20180130
- UDISK LABEL : Polaris
- SERIAL NO. : 88101f7866d700000000
- IMEI : NULL
- TYPE : GSM

I tried to install more than 40 different roms and none of them work. Only one rom works, and even then when I install it the touchscreen doesn't work.
The rom is:
FinePower N1_R01_06.26.2018_V1.3
and also:
FinePower_N1_R01_V1.2_13.04.2018

The programs used for installation: "phoenixsuit" and "phoenixcard"

Can anyone give me a hand? where do i find this rom??
