How to Update iPhone 4 to iOS 4.1 Without Updating Baseband 01.59.00

In this guide you’ll learn how to update iPhone 4 to iOS 4.1 without updating baseband 01.59.00 which is unlockable.

update iphone 4 to iOS 4.1

Restoring iOS 4.1 on iPhone 4 also updates its baseband 01.59.00 to 2.10.4 which is NOT unlockable at the moment. So, iOS 4.1 is an alarming update for all those depending on unlock. PwnageTool by Dev-Team has the ability to preserve iPhone baseband but unfortunately it’s not yet updated with iOS 4.1 support.

When we talk about the jailbreak community, there’s always an alternate way to get things done. Notcom, the dev behind TinyUmbrella app that let you save shsh blobs for iPhone, iPad and iPod Touch has updated TinyUmbrella which now let you update iPhone 4 to iOS 4.1 without updating Baseband (Preserves baseband at 1.59.00 ).  Lets learn how to use TinyUmbrella to update iPhone 4 to iOS 4.1 while preserving baseband 01.59.00.

WARNING: If unlock is the only way for you to use your iPhone as a phone, we strongly recommend you to avoid iOS 4.1. If you’re brave enough to give it a shot, follow the steps below at your own risk. I have tested this method myself and it works like a charm.

same error for me. does not work.

iPhoneHeat October 11, 2010, 4:26 am

make sure you save shsh blobs for iOS 4.1 first.. via tinyumbrella ..
Then run the TSS Server. Make sure there’s no error.
Then restore 🙂

jose October 15, 2010, 2:13 am

I found the solution in a different howto explanation. In umbrella press adavance options and select firmware version 4.1. Then it will work.

you need to wait for 4.1 jailbreak since the 4.0.2 jailbreak is not coming. i am having the same problem. i have 4.0.2 fw so all we need to do is to wait… thanks to these guys who make that happen. once again thank you folks…

Hey iPhone-Heat,
I have question pls, I couldn’t fine the guide in site,
I have an iPhone 3Gs 16gigs with FW 4.0(8A93) & BB 05.13.04-
I jail-broken it via jailbreakme last August and unlocked it by UltraSn0w 1.1-1 * I got my iPhone from Orange UK, early of 2010. lol
I wanted to Restore it with the same FW.4.0(8A93) but, I don’t know is’t easily without effects if I pressed ** shift & restore button on iTunes. or it would change something and I never could install the iOS 4.0 again, I have saved my SHSH Blob, But I don’t want to reply what Happen with me in 3.1.3. is any post in site would teach me how to restore my iOS-4.0(8A93).

iPhoneHeat October 11, 2010, 3:37 am

monisnerdy October 11, 2010, 11:05 pm

any luck anybody ?

iPhoneHeat October 12, 2010, 12:39 am

save SHSH blobs for iOS 4.1 first

Head Honcho October 20, 2010, 3:17 pm

How do you save SHSH blobs for 4.1 first if you aren’t on 4.1 yet? You have to install 4.1 then save but then your baseband is already altered. I don’t get it. How is SHSH blob saved when you are still on 4.0.1?

vietboy678 October 12, 2010, 4:33 am

It worked for me! error 1004 showed up!!! THX alot.

iPhoneHeat October 12, 2010, 5:45 pm

great, have fun!

rsctan October 13, 2010, 7:43 pm

i have done this and it worked. i jailbreak my phone using limerain. however i cant find my facetime and mms tabs anymore under my settings. how do i fix this?

Head Honcho October 20, 2010, 3:19 pm

I had that off the first jailbreak. Before you could remove your Sim card with the phone powered on then put it back in with power on.

james95121 October 14, 2010, 2:16 am

The first steps worked for me got to 1004 erro. but when i tried to klick on “kick device out of recovery mode” nothing happens. What should i do?

james95121 October 14, 2010, 2:28 am

It worked! I had a problem kicking device out of recovery mode. i just had to restart tinyaunmbrella and it worked
