Thanks for the heads up. I just checked my boot version (SPL-1.07.0000). I will use SPL 2.47 to unlock my phone and do a reset again to check boot version. am asuming it will now be SPL-2.47. After I unlock my phone I will first need to update my radio firmware. I have radio 3.42.40 - inside this folder is a file TITAIMG.nbh. I will replace the one in SPL 2.47 with this new TITAIMG.nbh for radio 3.42.40 and run SPL 2.47 again to update radio. I hope this is correct. can you explain how to do this from bootloader screen or how it is done in basic steps so I know what to expect. OK Continue with what I think.. After I update the radio to 3.42.40 I will need to update the ROM. First to ROM version 3.1.2. This rom is in a .exe format so I will need to connect the phone to computer via usb and run the 3.1.2.exe ROM. I dont think I can use SPL to do it from bootloader screen? correct? If this is correct. Like BillThyCat said once I load 3.1.2 then load back my MSL/SPC setting via qpst. Once this is done I can run the latest ROM which I have to be 3.3.4.exe. Again the ROM is a .exe so I will not be able to do it from a bootloader screen correct?

Thanks alot for your help. any way I can call you or chat with you when I do the upgrade? I just dont want to brick my phone.

OK i think i am in a little trubble. I update to 2.47 to unlock the phone and verified it was unlocked by pressing the reset buttons. after that I loaded a radio firmware 3.42.40 and placed it in the root of SD card as name TITAIMG.nbh. I did a power + Camera Reset and updated the radio. It failed the first time so I pressed reset and it started back up and finished properly. Now I want to load the ROM but after power back on the phone or after reset I am stuck in the HTC Smart Mobility screen. It will not boot into windows mobile to connect active sync and run the ROM update. Any Idea of what I can do. I hope I did not brick my phone.

Just press camera+power+reset and see what bootloader says
from 2.47 or 2.40 bootloader you can

a) copy nbh to card and flash from bootloader
b) connect to computer and flash ROM

*edit* just wanna note that activesync will not connect in bootloader mode, but you can flash a ROM...

Thanks alot Puff....you guys are the best...I was able to update the radio and rom after extracting the .exe. I am up and running on windows 6.1. the only thing is my internet connection is not on...i am assuming I will have to call us cellular and get my connection setup again with user name and password with #777 being the number i think.

Is there anything else I need to know after doing these updates...Like I hope 911 still works.

Thanks again everyone...also will need to check the GPS!!!! YESS!!

ok. stop right there, that's incorrect.
any .nbh left behind from NueSPL you want to delete

then you need to make sure your card is formatted FAT32
2GB or under reported to work, place TITAIMG.nbh in /root (root folder of mem card)
once you put the card in the device, press cam+power+reset and follow onscreen prompts

After I update the radio to 3.42.40 I will need to update the ROM. First to ROM version 3.1.2. This rom is in a .exe format so I will need to connect the phone to computer via usb and run the 3.1.2.exe ROM. I dont think I can use SPL to do it from bootloader screen? correct? If this is correct.

If you have WinRar or 7-zip you can right click the exe and locate the nbh
In 7-zip (which is FREE btw ) its Right Click - 7-Zip - Open Archive
Once you've extracted the nbh rename it TITAIMG.nbh

From here, you can guess the next steps.
Note: Depending on the exe ROM your talkin about, you may want to 'skip customizations'
When you install an EXE (or shipped) ROM, you are subject to new radio, new rom, new bootloader (if not unlocked with HSPL), etc... If its not your carrier you will want to skip customizations
to skip customizations, soft reset withing 3 seconds during the countdown...

Like BillThyCat said once I load 3.1.2 then load back my MSL/SPC setting via qpst. Once this is done I can run the latest ROM which I have to be 3.3.4.exe. Again the ROM is a .exe so I will not be able to do it from a bootloader screen correct?

If its an RUU folder, just look for the nbh file...
Otherwize, try the 7-zip trick
