PUMPKIN CAR STEREO SUPPORT CENTER

I bought two android stereos "pumpkin" last year on eBay, I made a silly mistake trying to update the android system but what I did was a downgrade, the thing is that It was running Android 4.4 but now it's running the 4.2, in this point I dont care what version it runs, the main problem is that I lost the radio tuner and I already tried all the canbus, radio chipset and the radio zone frequencies from the factory settings menu "126" but nothing works to me, i'm wondering if could you provide me the right Rom and MCU or any kind of help to fix my stereo please,
the pictures attached were taken when the stereo was running fine, but after my mistake it's running a different MCU and a different Rom "firmware"
please let me know if you can help me.
Thanks

Hi there
Really sorry for replying you late, cause I was ill and rest in hospital where there is no internet for right ear surgery, and my colleague forget to reply you here, hope you can understand!
Could you please tell me your ebay ID which used to purchase the item? So that I can check what item you have.
Best Regards!
