2. Change the recovery.img with the stock
recovery.img for your baseband ( if you are on
froyo , you must put froyo's stock

recovery.img , etc .. )
If you're with custom rom and you allready
rename your stock recovery.img to

or anything else , then just delete the CWM
recovery ( 5.0.2.7 ) , and rename stock

TO DOWNGRADE FROM ICS TO GINGERBREAD.
GUIDE FOR DOWNGRADE FROM ICS (404029
baseband) , TO GB (404020 baseband).
First of all you must be sure that you have
imei and baseband.
So, you must firstly flash a jb or ics based
rom, like icedroid ( http://forum.xda-
developers.com/show....php?t=2240898 ) , or
any other jb rom, just to have your baseband
and your imei back.
NOTE THAT YOU MUST HAVE IMEI AND
BASEBAND (404029) , TO PROCEED WITH
DOWNGRADE
After you're ok with imei and baseband, then
you can follow the procedure for downgrade.
if your imei is zero , or your baseband
unknown , you cannot proceed with
downgrade.
Before you do anything, first of all you must
take a backup of your imei.
Download 5iromtoolbox apk, from Pika's
thread ... http://forum.xda-developers.com/
show...php?p=24668935 ... and make a backup
of your imei.
After that you can follow the procedure below
to downgrade from ics to gb.
For example, if you're with icedroid rom ,
then ...
1. turn of the phone and remove sd card
2. i suggest to use an empty sd card 2gb for
downgrade (flash official GB )
3. Connect your sd card with card reader on
your pc and create a "dload" folder
4. Inside "dload" folder , paste the step2
( UPDATE_g.APP ) , and rename it to
( UPDATE.APP ) .. download Official GB here ..

5. disconnect card reader and , Put sd card in
the phone
6. Hold , vol+ vol- and power , until phone
vibrates .After 3 seconds , phone will start to
install step 2 , it needs almost 5-7 minutes to
finish.( alternatively you can do this without
battery , by holding the 3 buttons compo and
insert usb cable until phone vibrates).
7. after installation completes , pull out
battery and sd card
8. delete 'dload" folder from sd card and
insert it to phone again
9. hold power on until phone vibrates
10. wait phone to boot on official GB
DONE
This is MY way on flashing official firmwares , i
did it more than 7 times and having NO
problems , everytime the installation will
finished without a single problem.
When i was using cwm recovery 5.0.2.7 i was
having problems but when i use the stock
recovery then everything went fine .
