Suddenly can't flash!

[ismisunderstood]

Current Setup :

HardSPL (latest, 3.56 I believe)
Radio: 1.65.29.22 (from Niki or Neon, almost positive it was Niki)
Solace v3.1

Decided I wanted to go back to newest radio, attempted to flash to it; hit a snag at about 78%. Progress didn't update for a while, then to 100%. Update app said there was a flash error, and it did not complete correctly. Device restarted, stuck at bootloader. Re-attempted the flash, same result.

Next, I tried flashing AT&T's latest ROM. Stalled at about 76%, message about having a communication error, walked through the apps troubleshooting steps; it tried (and failed) again.

Tried the latest HTC direct ROM, same result.

Tried to flash the latest HTC via MicroSD card, got 20(ish) percent through, the Radio line then went red and said "RSA Failure". Then that whole process died on me as well.

The only way I can get my device back up to run MTTY to remove the RUU flag. When issuing the "task 8" command to format, it instead reboots the phone. The phone will come up normally after that.

Since I got it back up, I have tried flashing once again, and am getting the same result. Am I just stuck here now?

It's not that I don't like this ROM, I'm just wanting to update the radio. Any ideas what else I might be able to try?

Yes, thank you...except that I started my thread saying that the proposed solution was exactly what CAUSED the problem to begin with. I tried to flash to the 1.70.x radio, which is where I got the flash write error.

Anyone else?

Now that you can get it up normally, have you tried going to a stock HTC ROM first, then the new ROM, then the radio? Or HTC, radio, new ROM? I'd probably do it the second way. You said you tried flashing stock before getting it up again, and that you tried flashing after getting it back up, but you didn't state what you've tried flashing after getting it back up.

Since I've gotten it back up, I've tried both OEM and radio only. Both have the same result.

Really at a loss now as to what to try next.

Did you try the 3.29Hard2 SPL? I haven't encountered your issue and wish I could be mroe help here. My only thoughts would be to try a different SPL, or perhaps looking into the ForceUSB issue. Best of luck.
