Root Unrooting Thunderbolt on mac

[ILoveMyDroid]

Can anyone let me know how to unroot my Thunderbolt on my Macbook?

should be the same? you just need to download the "back to stock" firmware,rename it PG05IMG.zip and move it to the phones SD card.

you then boot into hboot and allow the phone to update.

do you meanP905IMG? or...and dont you have to run a bunch of terminal commands?

Pg05img.zip on the root of your memory card. Power off then boot into hboot (power and volume down), follow instructions

1)make sure your SD card is formatted FAT32
2)download file from link above
3)rename to "PG05IMG.zip" exactly (that is a zero,not an 'O')
4)transfer to the root of your SD card(top level-not inside a folder).
5)power off phone.
6)power on while holding volume down
7)you will see a blue status bar on the right top corner as the file is read. a yellow as it is checked
8)phone should tell you to push the power button to allow the update.
9)push power
10)DO NOT pester the phone while its updating. make sure its fully charged before doing this so it doesnt die in the middle.

when its done reboot to stock firmware and S-ON bootloader

*be patient... it takes a LONG time to read and check the file,and a LONG time to apply the update. if your phone doesnt ask you to update,youve either named it incorrectly,put it inside a folder,or possibly do not have a FAT32 formatted card(tho you should,as you needed to flash files like this to root in the first place)

hope that helps

Thanks! this worked like a charm! although my efforts of restoring everything from titanium backup were futile.

You can't restore anything via Titanium Backup unless you have root.

yeah,i was wondering what your last reference to titanium meant... i assumed that you were unrooting to return a phone for warranty(the reason most people unroot )

if you had other motives,my apologies for not asking,there may have been a better course of action than to unroot.

No i'm not returning the phone...that would be a sin I just want a clean upgrade to Gingerbread when it's served. Return the phone?! I say nay.
