JB 3GS on 4.2.1-Can I restore to 4.2.1?

[xboxbml]

Hello all. I JB'd on 4.2.1 Monday. It's been 2 days. Still getting This device is in the pending TSS queue in Cydia. Not sure if blobs are truly saved yet, and even if they are, can I restore to 4.2.1? I have read where you can't unless Apple is signing the version on which you JB'd. So at best, I would be able to restore only on 4.3.2, as this is current version Apple is signing. Is this the correct interpretation? AND how can I truly be sure my blobs are/have been saved in Cydia server?

You are correct.

To check for your SHSHs, use TinyUmbrella from thefirmwareumbrella.blogspot.com to your computer and click "Save SHSHs"

Yeah, I tried that yesterday...I got an error saying something about JMV or Java or something...Didn't work. This is a "work" laptop, so I have to watch what I install, and I may not have something that needs...Standard company builds and such...I was going to try it on my home machine last night, but forgot and fell asleep...hopefully I can try it tonight..but doesn't TU only check/save locally? I wouldn't know what to do in the event of a restore after that if I ever need to...Let me know. Thanks!

^TU requires Java. No way around it. If you can't update the laptop, try a different computer.

Yeah, I have Java 1.5.0_22...Not sure why it was complaining...Error says 'No JVM could be found on your system. Please define EXE4J_JAVA_HOME to point to an installed 32-bit JDK or JRE or download a JRE from www.java.com'...Like I said, I'll try it again tonight on home machine...Thanks.

Sorry all...should have reported back. I loaded java 1.6.22 and TU worked fine...I have all blobs from 4.1(which is interesting as this is a new replacement unit from apple store), and everything from 4.3.2-4.3.4 and 5 betas 1-3...sucks cuz every time I wanna run TU I have to deinstall java 1.5.22, install 1.6, run TU, then reverse it cuz I have a pc app that won't work on 1.6...oh well...thanks All.

Guess what all! This is now possible. There is a new program called iFaith out there that will take the blobs off the current OS that u r currently running, and create a signed OS of your current OS so u can restore to it!! Yea! I still have 4.2.1. I havnt had to restore yet but I now have the FW to do it! Just hope it works if I ever have to use it.

@Annie I have had problems with 50% ppl. They get stuck in dfu loop. If you twitter search ifaith all you will get is tweets to ih8sn0w saying his software doesnot work...

xtacy...... Yesterday I tried iFaith 1.1 on my 3GS 4.2.1. It got stuck --- did not work. Same as twice before.

Yesterday afternoon I download a fresh version from the official site. Strange, hash sum's did NOT match. Still version 1.1.

Bingo ... it worked.....

My new motto: Don't trust saved copies or version numbers. Get the latest before starting.
