	Boot mode help - « on: June 19, 2016, 06:52:08 PM »

Have an ME7.5, MTM chipped 518F box that I'm trying to IMMO defeat:

I have been unsuccessful in getting into boot mode though and would appreciate any troubleshooting tips.

I have a purple eBay cable configured as such:

Bench voltage is 13.5. I've tried grounding the boot pin (24) for various lengths of time from 2 to 10 seconds but I keep getting an immediate 'check cable' error - very quickly. I believe the cable to be good though, as I can connect via OBD with VAG Can commander. In addition, it is recognized by the Nefmoto flashing tool and connects via OBD with the Nefmoto tool.

No communication over OBD either, though it at least pauses for about 2-3 seconds before giving me the FAIL:

Hopefully, I'm making a simple mistake somewhere......

Thanks in advance.

try it with baud rate of 57600
Can you see the underside of the mtm board?

thanks, I have tried all possible baud rates.

anything in particular you're looking for on the underside of the mtm chip?

remove the riser, put it in boot mode, flash the eeprom, replace the riser.

It might slip right off. I'm not sure soldering is needed

It's clearly a simple socket. Pull gently and evenly.

	IMMO off please « Reply #7 on: July 13, 2016, 09:37:37 AM »

Turns out the bench harness I was borrowing from a reputable forum member had a fault in it. After reconfiguring it, I was able to download the 95040 on the first try.

Now, could someone assist with IMMO OFF please? Grin

thanks for the tips so far, was able to verify checksums on my immo defeated .bin. Now, I'm back to needing any boot mode tips!

C:\Users\Ranford>C:\Users\Ranford\Desktop\ME7gui106\ME7gui\ME7EEPROM.exe --boot
ode 95040 -wp1 "C:\users\Ranford\desktop\immoff.bin"
ME7_EEPROM v1.40
COM: 1, Baud Rate: 10400
Memory type: 95040, size: 512
Opening COM1 ... OK
Starting Boot_mode ... uC ID response 0xC5: C167CR ... OK
Sending Loader + MonitorCore ... MonitorCore successfully launched
Initializing registers ... OK
Sending EEPROM driver ... OK
Searching Chip_Select pin ... P4.7
Configuring SPI Interface ... OK
Checking EEPROM Status Register ... 0x00F0
Writing EEPROM ................................ OK
Verifying EEPROM write ... FAIL. (error=0x70101)
Closing COM1

So close, it seems! I've already tried all possible baud rates. I found an old post basically saying - "keep trying, ME7.x is stubborn."
Any other "variables" you'd recommend changing.....file name? location of the program? Thanks.
