Problem:
It is a Dacia Duster 2019 instrument cluster with RH850 processor R7F10400. After mileage correction by OBDSTAR Odomaster via OBD, the dashboard went black, I can write backup via obd but same problem always black screen.
Some others may have the same problem with the Renault Master dashboard with a micro RH850. Restore it with a Flash file that saved OBDStar, but it didn’t work. After writing the flash, the dashboard turned off and has no communication.
Solution:
First read what you have on processor (for backup), and after that write the flash that obdstar has read.
Some users have managed to solve the problem with Xtool Poland.
Here is the wiring diagram for X-tool (Polish device).
Read the instructions that you have on xtool, the order on write.
There are 2 blue pin. No need to split pin. You have the wiring connection on smok jtag (colours are the same on jtag and xtool), Use the same blue to elongate the wire.
The dash work after flash original file via xtool pinout.
SMOK will recover this cluster as well.

Remember write only FLASH!!! Don’t touch Dataflash.
After write dash is back to original state.
Be careful with jtag programmer in this dashboard, one wrong move and goodbye.
