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://xdaforums.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://xdaforums.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 .. http://www.mediafire.com/?7dyy01dzy68ns94

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 .
