TinyUmbrella 4.2.1 download available

Nov 27, 2010 - 8 Comments


The latest version of TinyUmbrella has been released and it’s compatible with iOS 4.2.1. TinyUmbrella lets you save SHSH blobs from compatible hardware, allowing you to upgrade your iOS version while maintaining older versions of baseband.

TinyUmbrella is of particular interest to those who want to unlock their iPhone, if you are looking to unlock your iPhone you should save your existing iOS 4.1 shsh blobs before downloading and updating to iOS 4.2.1. Here’s why this matters, directly from the TinyUmbrella developer:

Do not update to 4.2.1 for the baseband protection. TinyUmbrella is no longer able to kick you out of recovery for that version. TinyUmbrella still works for prior versions and will be able to restore and kick you out of recovery for those versions but 4.2.1 has a baseband version check that will stop your device from booting if your baseband was not updated.

Download TinyUmbrella 4.2.1

You can download the latest TinyUmbrella 4.2.1 from the developers site here or through the links below:

    hi guys i had to the same problem and i fixed it,,
    what you have to do is you can sett it to dfu mode,
    then go to itunes and itunes will reconise it as the iphone is on recovery mode,, then restore and update itt,, and later use tinyumbrella to safe your shsh and then downgrade to what ever version you want to jailbreak it you can jailbreak it from 4.2.1 using greenpoisen or 4.3.3 using on your iphone safari type in http://www.jailbreakme.com and your iphone would be jailbroken and you can use it again the way you want itt
