Hi, Donald and Adam! I wanted to bring up some additional information.
I cracked the screen of my old Pre3, and bought a new one (that had had the HP Profile bypassed). I have had one heck of a time trying (completely unsuccessfully) to get the new one to sign in to my HP Profile...and I think that @Garfonso figured it out: Since the old Pre3 had had its partition expanded, the HP Profile was different than the database that the new Pre3 expects.
My guess is that Doctoring doesn't bring the device completely back to "stock"; in other words, an expanded partition remains expanded after a Doctor...it just has the original software reinstalled. As a test (since I was concerned that somehow my Profile had become corrupted), I Doctored my old Pre3 and it signed in fine. However, I no longer have access to the bookmarks in the Web...the bookmarks list is blank, and I can't figure out a way to change (delete) the bookmarks that display when Web is selected. Another weird thing was that I had my old text messages at first, but after a couple of days all SMS had wiped itself automagically.
So...it seems that if you change the partition, and you buy a new phone and want to transfer the Profile to the new one, that you might have to change the new phone's partition first (after bypassing sign in) before you can sign into the Profile? Does that make sense to you? It also seems that once a device has been re-partitioned, Doctoring it may cause some unexpected issues...what do you think?
I haven't had a chance to re-partition the new Pre3 yet...although I am concerned about messing up some of the software (like the bookmarks and SMS)...unless the only real problem is changing the partition and then Doctoring it, since the re-flashed software is expecting a particular configuration?
Relatedly, do you know:
...is there a way to actually bring the device back to "stock"?
...is there a way to re-set the Profile so that you can keep your e-mail and password but blow away the rest of the database?
Absolutely LOVE the work you did! Just wanted to keep the conversation going in case others run into the same problems I have. I am currently bypassed and can at least use the Internet via WiFi and the phone on the new Pre3, so...gettin' there!
