So, Mr. "checksum error", is my phone dead?

[Guest urdone311]

I have an ATT, audiovox SMT5600. Have had it for almost a year now? And its been almost a perfect phone.

Paid to get it unlocked from Florin months ago.

Today I had the bright idea of backing up my ROM image. I followed the instructions, using Teratermpro and backed up my original ROM on the storage card.

The phone rebooted afterwards, started up just fine. Then i reset it again, and the prompt came up to download the Image from my SD card. I figured, what the hell, if its my original ROM image it should be fine. So i just did it to test, and hit "yes" to put the rom image on. Once again, this is my original ROM image and have never upgraded or downgraded, EVER.

Now my phone decides it wants to stay in the Canary screen every time it starts up. I've tried numerous times to download my original rom from the card, but all i get is:

FORMAT BINFS success.

Checksum Error!

and nothing happens.

So now i've gone and downloaded the Cingular ROM for SMT5600. Used WinHex, bought a storage card reader. Formatted the card with the new ROM, and i still get the SAME exact results.

Is my phone fried? It doesn't seem like it should be...i didn't think that i did anything really truly that drastic.

I have the same exact problem. I have a backed up ROM with the exact bytes necessary for the ATT ROM. However, I'm experiencing this problem resulting in the tri-color only.

I do have the SPL 1.01.0109. Is there anything I can do? Thanks....
