8210 Sometimes "CS", other times "just Read"

[dannyogolo]

Hello Guys,
Pls can someone tell me how to fix this phone?
Sometimes it shows CONTACT SERVICE, other times it shows:
SW<->ASIC
MISMATCH

USE SW FOR
DSP ROM O

I strongly suspect its hardware problem b'cos:
1. I can read the software with Rolis (I will try to flash it today)
2. When I switch it on, it shows CS straight.

I will appreciate any help.

10x.

can you tell me what you are doing exactly?

are you backing up your phone, then flashing it back to your phone (unedited) and it shows contract service?

SW<->ASIC
Mismatch means that you have loaded the wrong software version for that CPU!

eg. If you load a 8250 software onto a ROM5 8210 you will get this error!!

Contact service can be diagnosed by EEprom tolls! It will tell you the reason for CS!!!;)
