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
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)

So if i can't save version 4.0 or 4.1 will this still work for me to preserve the baseband if i update to 4.1?? i am only able to save 4.2.1 and 4.3b2
I am running on 4.0 with BB 1.59.00
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)?
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 http://www.fileserve.com/list/NBTtugZ

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.)
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.
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.
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.
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? :)

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
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!
