Also can you please ellaborate on the backup of current ROM procedure before proceeding with installing the new ROM. I had done the following:
1) Installed ROM Manager and booted into Recovery and created a backup of my current ROM
2) I now can place the zip file on my SD card and boot into recovery and do one of two things:
a) Clean/Wipe and than select ZIP file
b) Just select the ZIP file without cleaning or wiping
3) If for some reason the ROM fails, can I just use ROM manager and backup my original ROM
I dont care about programs much as I have just been 4 hours with the phone and dont care if all data is lost. Just dont wanna brick it.
4) The CoreDroid ROM is asking me for Radio upgrade. I am guessing I have to use the ENG-OFF tool before upgrading Radio. Just a dumb noob question, cant I use my stock radio with the ROM that came as a part of ACE Hack kit. I am little worried about upgrading radio as Attn1's post mention phone can be bricked
I don't believe you have to be eng-s off to flash coredroid. I flashed coredroid and I'm only S-off. Radio's vary from person to person. One radio for "x" person may be awesome but you try the same radio and the results are sub par. If the rom recommends a radio, I typically flash the radio since the rom includes that RIL for the recommended radio.
As for flashing radios, I know the eng-s off way is risky which is why I never tried it. I know there is a radio thread in the Dev section and if you search the specific rom thread you'll probably find someone who already made the "PD98IMG.zip" file for those who are s-off only. The Dev section radio thread will have the .zip file made and ready. Pretty much once you get the PD98IMG.zip file (yes, it MUST
be named PD98IMG.zip). you put it on the root of your SD card. Restart into bootloader, and run Hboot. It will find the img and boom, flashed radio. Someone else is gonna have to chime in on this for how to check as I'm not near my phone to see what apps I use, but you'll also notice that there are the md5 sum checks, that's just to a safeguard to be sure that the file isn't corrupt. If the file is corrupt and you try to flash the radio, nothing good can come from it. Hope that helps. A little tip with flashing radios, once you download the radio file, and you check the md5 sum numbers. If you try to flash the radio and the bootloader tells you img not found, and you renamed the file yourself and you added ".zip" to the end of the file, try removing the .zip because I did that once and the name the phone was recognizing was "PD98IMG.zip.zip"
