the mcu is empty reprogram it

I've tried reprogramming with both bins v4.47 and v8.21 from the beginning of this thread and both write and verify successfully using jlink. After programming both bins result in the same thing with the carprog mcu not being recognized when connected to the computer. The USB human interface doesn't show in the computers device manager either.
After quite a bit of searching and retrying I've come to the conclusion that either my at88 chip was empty or erased somehow during the reflash.
I found and flashed the v4.01 without at88 bin file from here in the DK forums and my carprog is back to being recognized by my computer.
Follow up question though....Am I limited to using on the v4.01 firmware or are there similar newer firmwares that will work without the at88 chip like the v4.01.
Thanks.
try other firmwares i remember having one fw8 that did the same so used another

Unable to find a working bin besides the v4.01 without at88 one that is currently working for me. I've ordered another carprog to give it a go so just waiting on that to try an updated firmware.
In the meantime, I've attempted to reset a Ford srs module and am able to read the 95320 chip with the a6 adapter and using v8.21 software can find the crash data and clear it but when I do a reread of the chip the crash data is still there according to the software.
I've tried it both reading the chip in circuit and removing it from the srs module. Gets the same messages both ways.
Plan on building the varprog test adapter in the next day or two.
Does the v4.01 firmware have issues writing and/or erasing the 95x chips.... especially the 95320.
Thanks

My mcu is the same as pictured online as car003.

I've replaced the 4x 74HC125 chips and waiting on the 47uf capacitor and 2 resistors to add in to the mcu.
I've built the a9 test adapter and the hardware test does not show any errors.
What other modifications should be done to the mcu?
Or is the hardware that I have just not able to write certain eeproms like the 95320?
Thanks.
Hi,
can I use to reflash clon v10.93 to v8.21?
thanks
Success finally....took 2 carprog mcu's to get to the point I'm at now. Carprog #1 would not accept any firmware except v4.01 without at88.... carprog #2 I was able to upgrade to firmware v8.21 bit received errors when performing the a9 test which I couldn't straighten out. In the end I swapped the at88 chip from carprog #2 to carprog #1 and now have a working mcu upgraded to v8.21. Reads, writes and looks like it can clear crash on the 95320 chip. Although I haven't reinstalled the rcm back into the car.
Thanks to all who have posted in the many threads here in the forums.
Hello.need advice..just bought a carprog v8.21 clone...it has on front 3x hct125m on the back is an 74hc125d...should i change that hc125d with hct 125M? 20200315_134554.jpg20200315_134512.jpg
i will try that..Thank you
In case anyone else needs this.
Worked for me after either my AT88 chip was erased or just simply blank.
FW 4.01 no at88:
