Did you use Tiny Umbrella to check which SHSH blobs are available?

SHSH blobs are required to restore any non-current iOS.
Download and run Tiny Umbrella (link below, post #1), advanced tab,
... check 'set Hosts to Cydia', Save SHSH, give it a min to finish;
... uncheck 'set Hosts to Cydia', Save SHSH, give it a min to finish.
... In the General tab, what SHSH versions are displayed?

While you're waiting, re-read the Tiny Umbrella post #1 for valuable info.

What do you see when you plug in your iPhone and open iTunes?

[jaswanthkoppu]

@iflames itunes pops a message that the device is in recovery mode ....

@mes.. i have saved shsh blobs but now tiny umbrella was saying no shsh blobs was available to this device.
right now tiny umbrella is not showing my device ..it got stuck in dfu mode..my phone was shown in "recent phone "

[Mes]

When you click on your 'recent phone' in TU, do you have a 4.3.3 SHSH blob shown?

[jaswanthkoppu]

shsh file is saved in my computer ..so how can i use that file to recover my device ...

@no it is not there

@no it is not there

I'm confused. Answered both yes and no ?!?

Do you have a 4.3.3 SHSH blob for you iPhone?

[jaswanthkoppu]

no i do not have 4.3.3 shsh blob ..

[Mes]

Does TU show --ANY-- SHSH blobs for your device?

[jaswanthkoppu]

no...but i found a file in that path which is mentioned in TU "CDocuments and Settings\koppu\.shsh"

[Mes]

The path is where SHSH blobs (if any) are stored. If it's empty, nothing is saved.

As I said in post #2, an SHSH blob for each iOS version is required. You appear to have none
However, Apple is signing (approving) iOS 4.1. Without other blobs, this is you only choice.

[jaswanthkoppu]

so how do i solve this problem ?
first how to get out of this dfu mode ?

with the help of snowbreeze i created a ipsw file and installed on it ..every thing worked fine but after installing it's again itunes says that iphone is in recovery mode...

[Mes]

When you restore without an valid SHSH blob, crazy unusual and bad things happen to your device.

I suggest restoring to 4.1, since Apple is currently approving that version.

iTunes 10 or higher is required.
1. Download redsn0w 0.9.6rc8.
2. Run TU, advanced tab, uncheck 'set hosts to cydia on exit', exit TU
3. Recheck hosts file. Delete all lines which contain: gs.apple.com
4. Connect the iPhone, wait a min or so, then hold power + home buttons for 6-8 sec
..... this is a forced power off. Listen for a computer high-low sound
..... If iTunes opens, leave it open. Ignore iTunes until later
5. Run redsnow 0.9.6rc8, select 4.1, select one (1) option, 'just enter pwnd-DFU'
..... follow the count-down timer. Verify successfully entered pwnd-dfu.
6. Open iTunes. Hold shift, press restore, in the new window select 4.1 iOS.
7. If iTunes 10xx error, use TU 'exit recovery' (not fix recovery)
Done. Restored to stock 4.1

8. To jailbreak, run redsnow, check "install Cydia".

[jaswanthkoppu]

Recheck hosts file. Delete all lines which contain: gs.apple.com

where is it located ?

right now there is no os in iphone the screen is blank

[Mes]

On a Windows sytem: CWindows\System32\drivers\etc\hosts

Question(s):
Why were you using Sn0wbreeze?
Do you have the iPad BB installed?
Do you need an unlock?

If you answered yes to any, stop. I'll change the instruction to build a custom firmware.

...right now there is no os in iphone the screen is blank

Doesn't matter.

[jaswanthkoppu]

1)downloading 4.1 ipsw
2)downloaded redsnow

4.1 takes 2 hours to download i'll try it after that

[Mes]

Ok. You forgot to answer my questions

Question(s):
Why were you using Sn0wbreeze?
Do you have the iPad BB installed?
Do you need an unlock?

[jaswanthkoppu]

yes i need unlock ..and i did not install ipad baseband

[Mes]

OK. Go ahead and try the procedure as written.

[jaswanthkoppu]

ok..i'll ping you after 2 hours ...i have one more question

"If iTunes 10xx error, use TU 'exit recovery' (not fix recovery)
Done."

but i can find the option on TU but its disabled.

host file as 2 lines in the last
"#127.0.0.1 gs.apple.com
#74.208.10.249 gs.apple.com"

can i delete these 2 files.
