[Q] Corrupt serial number and model ID topic

So I can't seem to find a solution to my specific issue. A little background first. I was on Modaco switch beta 13 and decided I'd move on to something else because 1) hadn't been an update for quite a while and 2) I really didn't switch back to Sense except when I wanted to play around with Zoe. I restarted into CWM recovery and tried to flash CM 11. It gave me an error and I realized I was downlevel on CWM recovery. I tried to flash an updated CWM and now only have access to fastboot. When I try to boot to recovery it gives me the HTC splashscreen and hangs. I tried TWRP, CWM, and stock with the same results.

Checking fastboot getvar I noticed some really strange entries. serialno and modelid were corrupt. Here is the output of fastboot getvar all

Code:

---

I read the following post to recover my serial number
http://forum.xda-developers.com/show....php?t=1724475

I don't believe I had the ENG hboot so I get the following:

Code:

---

fastboot oem writemid PN07120
...
(bootloader) [ERR] Command error !!!
OKAY [  0.012s]
finished. total time: 0.012s

# fastboot oem writeserialno 1234567890

I tried flashing the ENG hboot, but....

Code:

---

# fastboot flash zip ENG_hboot.zip
sending 'zip' (475 KB)...
OKAY [  0.242s]
writing 'zip'...
(bootloader) zip header checking...

(bootloader) checking model ID...

Yep, catch 22. Corrupt model ID, so it won't flash.

Another interesting thing I noticed was the 2nd line on the display in fastboot

Code:

---

**** UNLOCKED ****
M7_UL UNKNOWN SHIP S-OFF RH
CID=BS_US001
HBOOT-1.44.0000
RADIO-4A.14.3250.13
OpenDSP-v26.120.274.0202
eMMC-boot
...

Anyway one of the messages in the forums said that once they resolved the model ID and serial number everything worked.

Unfortunately this is my main phone and I'd like to use it. Not very useful right now. Anyone have any ideas?
