Did you try task29 yet?
Then flash the shipped rom.

Horndoctor,

Yes, I tried it through bootloader and the progress bar just sits at 0%.

I also tried it through the sd card and the screen just shows Loading... :confused:

Re: Sprint HTC Touch Pro 2 in reboot loop
 

you're tp2 is already locked, thats why it fails when you try to relock it.

Re: Sprint HTC Touch Pro 2 in reboot loop
 

and since your phone was not unlocked, that works in your favor. im guessing that the device is already active on an account with sprint? if so, your best bet is to call sprint and tell them you're phone is not going pass the bootloader after a hard reset. like i said...they'll most likely do a warranty replacement. just tell them you bought a tp2 over a month ago without saying it was from ebay.

or...you can try to see what sprint can do for you by contacting one of the sprint employees that happens to be a member of this forum. i was reading an old thread last night where they identify themselves....but can't remember where in the forum it is. i'll post link to the thread as soon as i find it.

edit...
here's the thread with sprint employee members...

Re: Sprint HTC Touch Pro 2 in reboot loop
 

Today, the same thing has happened to me. However, in my case, my phone was unlocked and this happened after I did a successful Task29. I completed the Task29 last night, but did not flash a ROM on it at the time, as it was getting late and I was tired. Instead, I shut the phone off and left it to charge using the AC Adaptor. This morning when I went to go turn the phone on, I noticed it is in the constant reboot cycle just like in the case of the OP. The phone wont stay on long enough for me to relock it and flash it to stock. Matter of fact, it shuts off within 10 seconds. I called Sprint and they offered to ship me a replacement battery as I have insurance and Im still under the 1 year manufacturers warranty. I hope to god that it is just the battery that is toast. I tried all the steps listed in this thread, and can't get it to even power on for longer than 10 seconds. Dog Mom, did you try charging the phone using the other charger? I read in another thread of a member having a similar issue. He stated that after a few days, the issue went away by itself. Perhaps the phone needs to be totally free of any electrostatic charge remaining.

Re: Sprint HTC Touch Pro 2 in reboot loop
 

Yes, I have charged the phone completely with 2 different chargers and using 2 different outlets. We have even swapped the battery out with the other HTC devices that we have.

Re: Sprint HTC Touch Pro 2 in reboot loop
 

Unfortunately, there is no active account associated with this device. The devices were purchased to be used as handheld PCs. I appreciate the info and I will search through that thread as well.

Re: Sprint HTC Touch Pro 2 in reboot loop
 

oh ok. that clears it up. i was wondering why you weren't taking it to sprint. if you can't find a solution for the problem, you can contact HTC directly and see if they will replace your device under warranty. either that or if someone in the family/company has a sprint account, you can do a phone swap online and then after 24 hours of activating on that line, contact sprint.

Re: Sprint HTC Touch Pro 2 in reboot loop
 

I just tried flashing from the SD card and I noticed that when the bootloader screen appears, there is an error code behind the bootloader information. I can't make out what it says and the bootloader screen only appears for a few seconds before going through with the update. The update loads and still shows successful, but once again, we are back in the reboot loop. Any idea what the error may be and/or how to correct?

Do you think the SD card may be bad? We don't currently have a spare, but we may be able to get one over the weekend to try.

Thanks!

if you think the sd card is bad, then take it out and leave it out. doesn't need to be in there for anything.
