Question about Nokia 6100
This tutorial will show you how to upgrade your iPhone 4 to iOS 4.3.1
without upgrading its baseband using TinyUmbrella for Windows.
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!
Download TinyUmbrella from here Also make sure to download the iPhone 4 iOS 4.3.1 which you can find here.
Double click the downloaded TinyUmbrella.exe file.
If you get a Windows Firewall notification, check both boxes and click Allow Access.
Make sure the device is connected, and Umbrella has detected the type of device and its firmware.

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 nokia 6100 contact service solution please - 47454.pngith a device OTHER than iPhone 4.
Place your iPhone into DFU mode by holding down both the Power and Home buttons for ten seconds, then release the Power button and continue holding the Home button for another 5 seconds. You can find help with DFU mode here.
Fix Recovery in TinyUmbrella is currently not working. Download this standalone .exe file to fix recovery on 4.3.1. Extract the file and double click on fixrecovery43.exe. A command prompt will open, and the program will go through the process. During this time, you will notice scrolling text on your iPhonnokia 6100 contact service solution please - 50102-500.png
Your iPhone will now be on 4.3.1 with the 1.59.00 baseband! (Which means you can now unlock using this tutorial)
