Please post a picture of the PCB to help figuring out which specific model you have and if it got a genuine ATmega. |

My board picture this thanks |
| madires:
Your T7 is an early version and has a genuine ATmega. Remove ZD1 (6.8V TVS) and DZ2 (SRV05-4) and try again. If the tester still shows "Cell" then the ATmega is damaged. |

hi i try it but not work it same. if i bought this chip is it run? it adapt my board? thanks for help sory my english is bad. |
| madires:
You can replace the ATmega and program an OSHW firmware. You'll also need to reprogram U4 or replace it with a simple two-transistor circuit. |
