Sb6121 Clone Help

Post by lake207 »

I’m trying to clone SB6121. I did use Separate 3.3 V on pin 2. I did got the readout from the chip. But the problem is when I read the flash from the first modem and write the flash to the second modem the modem does not boot up and if I erase and rewrite the original information the modem boots up no problem. Same thing if I read the second modem and write the information to first modem the modem does not boot up. And I also have tried jumping the pin 1 pin 2 and pin 10. Same thing.

Can you post your backup of the first modem?

Your read back of the backup file is not right. Might need to use slower clock to read back.
