matt April 7, 2013, 11:34 am

After going through the process described above Greenposi0n tells me “Jailbreak Failed :(“. The computer I’ m running it on is Win7 x64. I have an ipod touch 2nd gen, MC series, running ios 4.2.1, freshly restored from iTunes.

Is the MC series supported? Many of the other pages I’ve read about jailbreaking the 2G with redsn0w and another one I don’t recall indicate the MB series isn’t supported. I tried greenpois0n because this post said it would work — http://www.jailbreakqa.com/questions/14314/how-to-jailbreak-ipod-touch-2g-mc-model-421/40505

Clint June 14, 2013, 7:04 am

Trying this on 3G Ipod Touch using windows 8 and the first step where we must hold the sleep and home button at different times only sends the ipod into recovery mode. Not sure what to do at this point.

LH August 11, 2013, 12:01 am

Ipod 2G 4.2.1 fresh install. Successful jb w/ greenp0ison and didn’t find cydia on screen but found it in a search and ran it. Got “warning – you are running out of disk space” message, pressed dismiss and it seems to have loaded but no icon. Going back to loader and run again but it says already loaded. What to do now? Redsn0w, from what I have read is a tethered jb so has this been a complete waste of time? I’m brand new to this as I haven’t been all that excited about apple and their need to make you buy new and expensive devices on a regular basis.

Avkash Saini August 26, 2013, 3:50 pm

Thank you very much,,,,,,,,,,,,,,,,,,,,,,
I have ipod touch2 & i was going to discard this bcz it was not usable for me but after reading this art. it is usable now………….It is working…..

Mudball August 27, 2013, 2:17 am

I try to do it, Im at the step after it re-boots, there’s no icon on my home screen, and jsut the default ipod apps, nothing else.. what do i do? :\

joneslady January 23, 2014, 10:39 am

I’m having the same problem…did anyone ever give you a solution? Jail break was successful, rebooted, I unlocked the ipod and the loader nor cydia is there…

Addason August 28, 2013, 10:14 am

tried with an ios 4.2.1 and at first it went to the unlock screen then it just turned black and won’t turn on. What now?

Luis September 3, 2013, 3:40 am

I’ve jailbroken it correctly and it restarted, I clicked on the loader and clicked “install Cydia” and it says “downloading 0%” and it stays there forever and then eventually says “The request timed out” or “Please make sure you are connected to the internet before you launch loader”. I’m clearly connected to the web (I can browse the web with Safari fine). Can someone help me?

jhong fruza September 9, 2013, 11:38 am
