I have posted this before but I dont recall where,
You do not need to change rom to get diag mode
you can use terminal emulator, or adb shell and at the
# prompt use this
echo 1 > /sys/devices/virtual/usb_composite/diag/enable
Then when done restart phone or use
echo 0 > /sys/devices/virtual/usb_composite/diag/enable
As I mentioned before you do not need to switch roms just to access hidden menu, use the commands in terminal emulator or in adb shell.1. Make a backup in CWM of your current setup
2. Flash Halfass or CTMod2.5 ROM
3. Access hidden menu ( that's why you need Halfass or CTMod2.5 ) and change PRL
4. Restore previously made backup
PS: Gotta check, what PRL is working best for you. As far as I understand, there are NO city specific PRL's... Just try several of them )
Yes to update prl through the phone you would need to change roms.Or to update ota, once you have halfassrom or ct2.5, go to menu> settings> about phone> system updates> update prl
However you can google for any prl, all the boost, and sprint as well as any other carriers are readily available online.
