Doomboot.B is close variant to Doomboot.A. The major difference between
Doomboot.B and Doomboot.A is that the Doomboot.B does not contain Commwarrior
and contains application that reboots the phone.
Doomboot.B pretends to be an utility that can be used to reboot a phone.
The Doomboot.B actually contains an utility that is used to reboot the phone, but when user
uses this application, the corrupted binaries in Doomboot prevent the phone from
booting again.
If you have installed Doomboot.B, the most important thing is not to
reboot the phone and follow the disinfection instruction in this
description.
If you have rebooted the phone and the phone will not start again, the phone
can be recovered with hard format key code that is entered in the phone boot.
Please refer to your phone manual for the code.
