[visavis88]

2025 Mazda CX5 VC85-57K30 RH850 LOCKED (R7F701330A)

Could you please tell me what blocks to clear with "Erase DF Block".
Option 1: (2E80 and 2EC0) and (3000 and 3040) - according to pdf
Option 2: 2EC0 and 3040 - According to video from the seller (https://iobd.io/) 

Which one is it?
Last most module stopped communicating, so I want to be more careful this time.

I did option 2, now module has no communication. 

What I did:

 

1. Used a separate 1.2V for the core continuous (stabilizer adapter from the store didn't work). 
2. Connected Glitch. (I didn't connect GND from the glitch PCB because it is already connected to other ground pins through GProg adapter).
3. Tried with capacitors, didn't work -> removed all caps.
4. Del_Sel 4 -> read DataFlash1 -> Erase Block 2EC0 -> read DataFlash1 (to verify).
   • Same with block 3040.
5. Read/clear EEPROM.
6.  Put the caps back
   • Used microscope and voltmeter to double check.
7. No communication.

 

Did I miss a step? What can cause no comm? Can Glitch attempt cause memory to be erased?
