iPhone 3GS running 3.1.2 (wanting to update to 4.X.X

[Egypt]

My 3gs is on 3.1.2 and I wanted to update it to 4.2.1 or anything below 4.3.5 but i need it to be unlocked for tmobile and i cant auto update with itunes since latest is 4.3.5. now I tried downloading the official 4.2.1 dfu mode shift+ restore but i got an error that required me to run tinyumbrella so i did. but its now stuck in DFU mode. I used iReb also for another error. I looked up a tut an found that i could use a official ipsw with resns0w so i could than shift restore with custom ipsw on itunes and I did and as soon as it finished the countdown saying succesful iphone will now reboot, itunes automatically says that this phone is recovery mode blah blah blah hit restore. How do I get out of this loop? I do not have SHSH blobs saved I do not mind updating to at most 4.3.3 Any suggestions would be deeply appreciated!

I don't know where to begin. I'm afraid you've really messed up your unlock.

No SHSH blobs .... means .... you can't do anything but load the latest and greatest (4.3.5)
Did you run Tiny Umbrella to check? In Cydia, are any green numbers show at the top of the 1st page?
(Note: 4.1 may be available from Apple .... but your unlock is still questionable)

Run Tiny Umbrella, Save SHSH. Advanted tab, check 'get from Cydia", Save SHSH
What is displayed?

What were you saying about 4.1?

[iYeow]

You should look under general tab for shsh blob. You can restore to 4.1 firmware , just point to apple server by deselect : set hosts file to cydia , close it. Restore to stock 4.1 either by recovery , if not then dfu mode , error 1015 will pop up but can be kicked out.
Once you are at 4.1 , jailBreak with lime rain

I was thinking about a custom 4.1 .... to leave the BB alone just in case he got lucky.

[iYeow]

That is a good idea too

@Egypt , go build a custom firmware of 4.1 from snow breeze 2.1, if you need activation, use expert mode. Use redsnow b6 or b8 to only put iPhone into dfu mode or even ireb can do it too. You can either point hosts file towards apple or run tss server from TU with downloaded 4.1 blob in TU , run iTunes and shift + restore to cfw (custom firmware of 4.1) .
Or if you think you already have a non unlock able bb, then restoring to stock fw of 4.1 is easier , you still need iPad bb to unlock which breaks your gps functions, meaning your locations services will be out by a couple of miles

I tried that first part without the blob in tu but i was running tss server. Everything worked but like i said before its stuck in DFU mode. as soon as it said phone will reboot after successful restore.....

[iYeow]

Ok , restore to stock 4.1 , don't use tss server, point hosts file towards apple server

[Egypt]

okay im running tss server and i have apple server unchecked but im getting a 1015 error. i use ireb like a billion times but its not working

[iYeow]

Use exit recovery to kick out error 1015 or 1015 recovery fixer

Tried with no luck. Ended up updating to 4.3.5 thanks for the help though...
