This tutorial will show you how to upgrade your iPhone 4 to iOS 4.3.1 without upgrading its baseband using TinyUmbrella for Mac.
Currently there is an issue with older basebands such as 1.59.00 and FW 4.3.1. Until ultrasn0w is updated, you will only see one bar under signal strength.
Please Note: This ONLY Works with the iPhone 4!
Step One Download TinyUmbrella from here. Also make sure to download the iPhone 4 iOS 4.3.1 firmware which you can find here.
Step Two Double click the downloaded TinyUmbrella pkg file to and follow the prompts to install the application.
Step Three Double click to launch TinyUmbrella from your Applications folder.
Step Four Make sure the device is connected, and Umbrella has detected the type of device and its firmware.
**If you haven't already saved your iOS 4.3.1 SHSH blobs then click Save SHSH. Make sure they successfully save before continuing.
Step Five 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 Six Open iTunes by doubling clicking its icon in the dock.
Hold down the Option key and click Restore
Select your iPhone 4.3.1 firmware file from the popup window that appears and click Open.
Click Restore to begin restoring your device.
Step Seven iTunes should give you error 1013. This is what we wanted, as it notes the baseband has not updated :) Click Ok and close iTunes.
If you get a 16XX error then try entering DFU and go to step 5. If your restore does NOT end in a 1013, it means your baseband was updated. This is likely because you did not have the TSS server running OR you updated without TinyUmbrella OR you are working with a device OTHER than iPhone 4.
Step Eight Fix Recovery in TinyUmbrella is currently not working for the latest firmware versions. Download the standalone Fix Recovery to kick your device out of recovery mode on 4.3.1 from here.
Extract the file by double clicking on the downloaded archive.
Double click the fixrecovery43 program from within the folder we just extracted. During this process you will notice scrolling text on your iPhone 4.
Step Nine Your iPhone will now be on 4.3.1 without having upgraded the baseband! If you have the 1.59.00 baseband you can now unlock using this tutorial).

Hi. I need Help. I'd like to update my jailbroken iPhone 4 (9A405 MC608L firmware 04.10.01) actual os: 5.0.1 to 5.1.1. I tried with redSn0w and i couldn't
I got this error after upgrading Jailbroken and Unlocked iPhone 4 with baseband 01.59.00 on iOS 4.0.1 to iOS 4.3.3 using this guide:
"Unable to find gBdevList
Unable to find fs_mount
Unable to find fs_unmount
Unable to find fs_load _file
Greenpois0n initialized"
It was a mess to fix it but I was lucky enough to find this post that save my life and USD 400 that I paid for my iPhone:
These are the steps that I followed:
1- Open Tinyumbrella and click Fix Recovery
2- While it is launching Greenpois0n go to the terminal and run ./irecovery -s a couple of times. That stops Greenposon to load and the iPhone will get a white screen.
3- Then I opened Redsnow, Extras and click on PWNED DFU.
4- Finally I Restore from iTunes a Custom ipsw 4.3.3 created with Pwnage
So I followed the steps and I have managed to upgrade ro 4.3.1 with the baseband the same at 1.59.00. But on my phone there is no cydia app to be found. Once I update the version am I supposed to JB the phone, but wont that update my baseband as well. Anyone have any ideas.
Hey everyone! I was wondering if this works with Verizon's 4.2.7? I keep trying to downgrade to 4.2.6, but its not allowing me to. Even after TinyUmbrella, 74.208.10.249 gs.apple.com, and DFU mode. I tried doing this method a bunch of times but kept getting the "Setting to configuration 1 Setting to interface 0:0 opening device 05ac:1281... " thing on the recoveryfix. I haven't tried putting it into DFU mode during that time, so I'm going to try again soon, but I'm also wondering if it has something to do with me being on my college's internet. Any suggestions?
Hi everyone. I've got stucked on RECOVERY MODE after step 8.
Received error 1013 with no problems but, when i had to use TinyUmbrella FIX 43, the terminal keeps looping on "interface 0:0..." and cant get out of recovery.
Anybody could help me please? I will appreciate so much.
Phone was in 4.0.1. bb 01.59.00
Upgraded to 4.3.2, trying not to change de bb, using this guide.
Thank you!!

What's your BB (BaseBand) and your device?
You can make a custom firmware with Pwnage Tools to preserve your BB, but if you are using an unlocked iPhone (Software Unlocked) first look your BB to know if you can upgrade it!
i tried this today(4/6/11) and i read the comments and put my iphone 4 bb 2.10.04 into dfu mode and ran the fixrecovery43 and when terminal comes up at the end it says Reason: Incompatible library version: fixrecovery43 requires version 6.0.0 or later, but libcurl.4.dylib provides version 5.0.0. Trace/BPT trap logout
any help will be truly appreciated. thank you.
i updated my i4 to 4.3.1, after unlocking it with ultrasn0w, i can see 1 small singal bar, which i should cuz its not fixed yet. But i cant even see the name of my carrier, and hence can not make/recv calls.. and idea ?
