Interesting Update: I started to take more risks. (All flashing was done by SD method.)
I re-flashed radio 3.42.50. Although the flash was completed there was no change in results. I re-flashed both ROMs that had worked and ones that had no change. And still no change.
Then I decided to flash any ROMs made for Alltel (Titan) that I could find. (I wasn't really seeing if the ROMs had radios in them.)
I flashed
nueROM_MTitan-201-201-spackr.rar which booted to the 2nd splash screen [AAAHHH!!! something different!!!] The following information also appeared on the screen:
Nuekernel 3.01
Build 109(c) 2008 No2chem
High Mem (camera disabled)
HTC
M09
B03
P=DCAAXAM 4350H
R=3.42.50
D=3.56
After resets and re-flashes of this ROM I could not get past the 2nd. Splash screen.
I next went to the link from:
http://forum.ppcgeeks.com/showthread.php?t=22132&highlight=boot+stop+splash (post # 3)
I flashed:
Alltel_titan_20273_a2.rar . However, the result was the same as my original problem.
I skipped the .exe file that was in the list.
Then I flashed
Nex_5054.8_Alltel_b3.rar and
SUCCESS!!! It booted. (I did not install any of the CABs listed on the screen.) I can enter all of the menues. I don't know if GPS still works. The green LED flashes like it did when I could use the phone. (I can't use the phone now because I reactivated my old phone.)
I have not tried these other ROMs that are also listed:
Nex_5054_Alltel_b2.rar
Nex_5054_Alltel_spb'd.rar
Nex_Alltel_dcd_3.0.0.rar
Nex_Alltel_superBB_chick.rar
Before I do any more test-flashes, can anyone tell me:
#1) what additional information I should copy off my phone before I try these other ROMs?
#2) can anyone tell me the differences in the ROM that works and the ones that did not (so I know why
Nex_5054.8_Alltel_b3.rar works)?
And #3) Does anyone have any suggestions before I proceed with testing other ROMs or try cooking my own again?
Thanks, in advance, for your help!
