I have followed the directions for the Sprint HTC Diamond Touch ROM update found at this thread:
*Leaked* Sprint Diamond ROM v2.00.651.1 CE OS 5.2.20764
In particular, I loaded the ROM from the following link:
Victor_C_SPRINT_WWE_2.00.651.1_RS_1.11.00F_NV_1.53 _PRL60650_Test
Phone boots up fine with the 2.00.651.1 ROM version. However, the following ROM updates
DO NOT WORK:
original stock Bootsplash's to flash to get rid of "test"
[Jan 15th New Sprint Radio V1.11.00F] Official CDMA Diamond Radio Thread
When the ROM updater tries to do the update routine, it stays stuck at 0% then attempts recovery.
The phone is not bricked. I was able to flash it again with the leaked Sprint ROM, so nothing got screwed up as far as I can tell. Just figured I'd warn anyone attempting the other two ROM updates.
Also, if anyone knows of a working ROM update to get rid of the "Test" text during boot-up, I'd appreciate it. I don't care much for the text, but if I end up selling the phone it will seem as though I'm trying to sell a test phone that wasn't supposed to be for sale.
Thanks
