This tutorial will show you how to upgrade your iPhone 4 to 4.1 without upgrading its baseband using TinyUmbrella. We recommend reading the TinyUmbrella Read Me Located here before doing anything. The Mac version of this tutorial is here.

Please Note: This ONLY Works with the iPhone 4!

Step One
Download TinyUmbrella from here Also make sure to download the iPhone 4 4.1 Firmware Located Here

How to Update Your iPhone 4 Without Upgrading the Baseband (Windows)

Step Two
Right Click the TinyUmbrella exe (umbrella-4.1.6.exe) and Choose Run as administrator from the contextual popup menu.

If you get a Windows Security Alert, make sure both boxes are checked, and hit Allow Access

Step Three
Make sure the device is connected, and Umbrella has detected the type of device and its firmware.

Step Four
Make sure Cydia or TinyUmbrella has an SHSH of the latest firmware. You can do this by simply clicking Save my SHSH. If you have problems saving the SHSH follow this tutorial here first.

Hit Start TSS Server and make sure you receive no errors.

Once The TSS Server is "running" successfully, umbrella will kill iTunes. Leave TinyUmbrella Open.

If you do receive an error, DO NOT continue. Your restore will not work if the TSS server cannot be started.

Step Five
Open iTunes and Hit Shift+ Restore.

Browse to and select the iPhone 4.1 Firmware File.

Hit ok to Restore iPhone

Step Six
iTunes should give you error 1004.
This is what we wanted, as it notes the baseband has not updated :)

Step Seven
Go back to the TinyUmbrella window and Click Kick Device Out of Recovery
If you have issues here, try closing and re-opening TinyUmbrella.

Your iPhone will now be on 4.1 with the 1.59.00 baseband! (Which means you can now unlock using this tutorial)

Can I use this method to update from 4.1 to 4.2? Thanks

David - November 29, 2010 at 1:59am

no you cannot. it is only for updating to 4.1 from a lesser firmware.

Hello, I have Iphone 4 with 4.0.2 sw and 01.59 bb. Umbrella have saved only 4.1 shsh. Do I still can update may iphone to 4.1 version (without baseband upgrade)?

mbgriffi - October 29, 2010 at 8:54pm

This didn't work for me at all. I got Error 11.

Tolga - October 30, 2010 at 4:31am

It works perfect. Are you sure your iPhone4 in dfu mode and shift restore this firmware. (when you see error kick your device normal mode with Tiny Umbrella.)

mbgriffi - October 30, 2010 at 6:45am

Yup I am sure. To be clear though I am ALREADY on 4.1 with my firmware at 02.10.04.

tolga bisi sorcam shift restore dedigin olay nedir? klavyedeki shift tusu ile itunes deki restoreye ayni anda basmak mi? yoksa farkli bisimi?

I'm one of the few people who got stuck in the middle of restoring process. Actually, the restoring process wasn't stuck; it was completed. But, iTunes error message didn't pop up. So this is what I did. 1. When the restore bar on phone got stuck half way, I let it sit for about a good 10 min. 2. Then, I hold down Power + Home buttons to do a force shut down. Then, the iphone rebooted into a recovery mode and it automatically recognized in the TU. 3. I kick the phone out of the recovery. The phone rebooted and I got to the activation screen (Emergency call only) 4. I put the ATT sim in and activated with iTune. All is done and I'm my iPhone 4 is on iso 4.1 with baseband 01.59.00. Good luck to all. I try to make it as detail as possible. If anything unclear, ask in the comment.

Jakroval - October 17, 2010 at 2:42am

The spec: iPhone 4 from 4.0.2 to 4.1 (with only 4.1 shsh saved) TinyUmbrella 4.1.9 Windows Vista 32 bits and iTune 10 (latest one)

DT - October 17, 2010 at 3:35am

Thank you very much. I had the exact same situation. I was a bit scared when the restore process got stuck in the middle. And I did what you described.

mbgriffi - October 17, 2010 at 12:08pm

I ended up getting my baseband upgraded and am now stuck :(

Obskure - October 17, 2010 at 12:59pm

I had exactly the same problem. Left TU running along with iTunes. (won't close because it thinks that the iPhone 4 is still restoring) Held the power and home buttons for 10 seconds and the phone reboots to recovery mode. Use Tiny Umbrella to kick out of recovery mode. Phone activated appears on screen and all is well. TU recognizes phone is on 4.1 with 1.59 baseband fw.

Mark - October 17, 2010 at 1:40pm

sorry to hear that, the only way that could be is if TU wasn't running (or running properly). luckily CL is a good haven to sell yours off, and buy another one? :)

ali - October 28, 2010 at 5:22pm

i'm in the same case of you, but when i kick device out of recovery it still reboot to recovery mode

Tolga - October 30, 2010 at 5:13pm

Download this firmware and install shift restore in dfu mod. When it's finished iTunes should throw up error 1004 don't panic Now you need to exit recovery mode. Click on Kick device out of recovery mode in TinyUmbrella or another program.. This firmware is not a custom firmware it's edited from original firmware..Your baseband stay in 01.59.00.. then jailbreak and unlock.. If your iphone4 stay in Apple logo you have to try this.. No facetime error. No network error. No any other errors.. No risk to baseband update.. its simple its like an original

newbie - October 15, 2010 at 12:16pm

Just got a 2nd hand unit 3Gs with firmware 3.0. Wanted to upgrade to 4.1 but worried it might be operator locked. Can't seems to find instruction how to upgrade 3Gs without upgrading the baseband

mbgriffi - October 13, 2010 at 9:51pm

After step 7 something when wrong. :( I restarted TU and hit Kick out of recover. now my iphone just shows the "Connect to Itunes" screen on homescreen. Itunes says : The sim card inserted in this iPhone does not appear to be supported. TU won't let me kick out anymore TU says : Device: iPhone4 4.1 (8B117) blah blah Baseband: 01.59.00 - ICE_2_6 What now? HELP!

joy - October 13, 2010 at 9:54pm

use limera1n it will jailbreak ur device n activate it n then u can unlock it with ultrasn0w.... try it n let me kno if it work

mbgriffi - October 13, 2010 at 11:34pm

There is nothing to jailbreak, I can't even unlock it. Its like the phone is wiped, brand new. The only thing I can do is "slide to make an emergency call". :(

mbgriffi - October 15, 2010 at 12:19pm

So I ended up getting a ATT sim card and upgrading to 4.1, which was a mistake because it upgraded my baseband and now I think I am pretty much screwed there is no way to go back.

Hasan - October 28, 2010 at 9:10pm

if your iphone was on the (connect to itunes sign) you were able to jailbreak it with limera1n because that sign means that the iphone is allready restored, you only had to restart your computer and simply put your iphone in dfu mode and limera1n it and unlock it. it happened to me, and that's what i did.

Mohammed Ali - January 23, 2011 at 7:12pm

After the step 7 the same thing showed on my iPhone 4 i.e. iTunes logo with an arrow upword n the only thing i can do is make an emergency call..... how do i get to the normal phone home screen and jailbreak n unlock it again using limera1n or whichever.....??? Plz advise thankksss.....!!

Mohammed Ali - January 23, 2011 at 7:34pm

i tried the jailbreak thru limera1n and it worked but i would like to know how do i unlock to use it to any simcard.....thanks alot.....!!

Frederick P Worthington - October 13, 2010 at 9:46pm

After step 7 I had to restart TU and then I hit the "Kick Device Out of Recovery", but something has gone wrong. :( iTunes now says : "The SIM card inserted in this iPhone does not appear to be supported" my iPhone has "the Itunes Icon -> USB cable" on home screen. TU when I restart says : Device iPhone4 4.1 (8B117) and it says Basebasd : 01.59.00 ICE_2_6 What do I do now? (Much thanks in advance)

joy - October 13, 2010 at 9:56pm

tasotat - October 12, 2010 at 4:37am

TinyUmbrella is not working for me... :( i have all the time the same issue : NOT running as administrator OR your hosts file is not editable - Cannot listen on port 80! TSS Server will not work! Please anyone help Running in windows 7..anyone help ?

Butchoy - October 12, 2010 at 2:16pm

I also got the same problem at first. But here is what I did that worked out fine: Turn your firewall off and/or if you have Teamviewer installed in your computer then turn it off as well before running umbrella. That's it!

tasotat - October 13, 2010 at 3:03am

i solved the problem...i turn off the Karspersky antivirus and that's it. Kaspersky listen on port 80...!!! amazing :)

Tim - October 12, 2010 at 12:30am

Worked perfectly. I did have to restart TU to be able to kick the device out of recovery, but I am now running 4.1 firmware with 1.59.00 BB, w00t

joy - October 12, 2010 at 10:01pm

Pratik - January 8, 2011 at 11:24am

Ya,how did u unlock the phone??

LeeSirc2002 - October 11, 2010 at 10:57pm

Well ended up using another computer / itunes 9 to restore... and now I'm just as good as if i would have just updated in the first place.

Ryan - October 11, 2010 at 9:05pm

So if my "Hosts" file already has the modified IP addresses, do I still click "Start TSS Server"? Or do I un-modify the "Hosts" file and then click "Start TSS Server"?

Jessica - October 11, 2010 at 1:07pm

I am a little confused, when I open TU, it automatically finds my iphone 4 running 4.0.1 8A306 01.59 firmware but the blobs that it saves automatically is for the 4.1.... So then I did the advanced option and I saved the blobs with the 4.0.1 also so I saved 2 blobs which one do I use to do the jailbreak successfully??? Thanks!!!

Jessica - October 11, 2010 at 1:26pm

The automatic TU saves as: iPhone4 4.1 (8B117) The advanced options saves: iPhone4 4.0.1 (8A306) (this is the correct current version of my phone)

JaTT - October 11, 2010 at 12:48pm

Perfect!! Thanks....

bentusi - October 11, 2010 at 2:06am

hello, In iTunes 10, when I hold "Shift" click "Restore", browse to iPhone3,1_4.1_8B117_Restore.ipsw, then I got the error, "iphone [phone's name] could not be restored because the firmware is incompatible". My phone is iPhone 4 on iOS 4.01 j/b using www.jailbreakme.com" umbrella-4.1.6.exe Thank in advance.

Diane Ford - October 11, 2010 at 6:42pm

If you downloaded the custom firmware on Internet Explorer it will be named iPhone3,1_4.1_8B117_Restore.zip. Rename it iPhone3,1_4.1_8B117_Restore.ipsw to make it compatible.

Ptic - October 10, 2010 at 10:21pm

Got error 3002, any thoughts. Thanks

Sam Sidhu - October 10, 2010 at 9:23pm

damnnnnnnnnnn Finallly . Worked In First Attemped . Awesome Work Guys . Hats Of To All Of You .

cdude - October 10, 2010 at 6:08pm

I finally got this working on another computer. Tried updating iTunes.. deleting and reinstalling iTunes.. nothing worked except doing it from another computer. Just for the record I did it with iTune 9 on an old computer. Still I wouldn't say this is a perfect way to update to 4.1 if you value you phone. Just one more example of what garbage iTunes is. Good luck all!

Laurenz - October 10, 2010 at 7:09pm

did u edit the hosts file in the others pc that did not work before? pls email me at renjo2007@yahoo.com. my ipohone 4 is bricked due to this tiny umbrella.

Rishi - October 10, 2010 at 4:02pm
