Sorry, one of my many typos Loly. I've corrected it.
Just as 25x9 C4 HWID 1947 have only one series of firmware versions, so does 2xx7/2xx8 C4 HWID 2077:

To recap the situation:- He was trying to patch V8.30 for C4 2077 but mistakenly used V8.30 C4 1947 instead [i don't know what version of 2077 was onboard previously but it's moot now i guess]
- It was flashed by RGN file but it seems not with safe convention naming XXXX10000.xxx.rgn so the flash was forced and accepted
- Apparently the unit boots but has no touch function.
- It is seen by PC so isn't 'bricked' in that sense.
- It cannot reach preboot because of the unresponsive screen
What's been tried so far:
An attempt to flash rgns 14, 127 and 158 from 2077 fw via SD also using Ldr.bin from 2077 fw but in a folder '1947' to match the unit's wrongly written HWID. That's resulted in 'Loader' displaying endlessly on the screen. No 'update.log' in the 1947 folder. I've now asked him to try two things: [i] remove last_id.bin if present and retry the flash in case regions 5 and 43 have been overwritten in the first attempt [ii] If that doesn't work but if the HWID in the XML is now showing as 2077 to change the 1947 folder name to 2077 and repeat the attempt.
New intended action if needed:
- If XML still shows 1947, then use the Ldr.bin from HWID1947 to try flashing the 2077 regions 14, 127 & 158 with override in RGN_Tool to 1947 of fw_all.bin for region 14 [127 and 158 have no HWID specified, they're XXXX in RGN_Tool].
- If that works and touch is back then force a flash of full 2077 fw as OUT.RGN in preboot to write correct HWID 2007.
I haven't thought any further ahead at this stage. What's your thoughts? Can the firmware be more deeply modded to force the correct flash if necessary?
PS: I've posted this summary because it's a bit hard to 'see the woods for the trees' in the numerous posts. It may help you or any other NSE with coding experience to see a clear way ahead if my basic attrempts don't work.
