FRM3 repair dump

[atomiczen]

I see a lot here on forum can repair FRM3 dump with corrupted eeprom from Pflash
how is possible to do? there's a software or only manual solution?
here a corrupted r56 frm3r pl3 r56 high eks 6135-3456588-01
there's someone could extract eeprom?

It is not possible to recover eee from P-flash, since it only contains the program and no car specific data.

You need to read the corrupt D-flash. This can be converted to an emulated eeprom (eee) since the same physical memory blocks are used for the emulated eeprom as for the D-flash. You can read the D-flash by assigning all memory blocks to D-flash when reading. In XProg, this only works when the FRM is in fact corrupt.

You can use my site http://tlvps.tomvanleeuwen.nl/frm/ to convert it. There, you can also download the source (Python) or a Windows build.
The source code more or less also explains what is done to convert the image.

When you have the recovered eee image, you can erase the eee and assign all blocks to eee and write the image.

when the frm3r is death (no conect) is the same process?

[tomvleeuwen]

This is only for FRM3R's that are dead.

If it is not dead, why would you want to recover the eee?

Are you sure you wrote to the eee section and not the D-flash section? Did it verify OK? I have tried using an empty EEE and the FRM could still communicate with the scanner, so if you have no communication at all it seems to me that you did not assign all blocks to the EEE section.
You can always program a different dump and then code it, but I highly doubt it will solve your problem.

Today conect again the fmr3 to the orange 5 ...and you have the reason.....i read the EEE and not change....ist the same.... i can erase a p-flash and d-flash but i can´t erase the EEE for replace with your repaired file...i does a some bad process?

thanks again for your help and time

I don't know how orange5 works exactly, I don't have one. In Xprog, it will just ask how to partition the device when you click erase.
But apparently on orange5, you have to do a "Full partition" and set DFPART=0000 and ERPART=0010 and then rewrite P-flash and eee.
