i do all of this steps but icon of cydia non apper in my phone after install jailbreak and when connect my phne with i tools said NO JAILbreaK ???
please help me
after 3 hours, it worked! thanks
Problems encountered:
1. USB communication problem
– had this, because i ran jailbreak on DFU mode right away.
– fixed by making sure you run jailbreak first with the phone "ON" and connected (not on DFU mode)
– then follow instructions
2. !mark (bang) DFU driver not found
– fixed by reinstalling itunes
– installing driver manually on device manager, (browse) target C:/
THANKS for the video mate!
>Windows 8.1 Pro

Worked in the same time like on video. Followed the steps. I did it so I can use Skype and Viber on it. That is next. Thank you! After this Cydia had 8 updates when I tried to get Appsync and I get POSIX Connection reset by peer… I'll just live it to run all of it.. maybe it just needs time.

Hi, I had been trying for days to get jailbreak to work. Found your Utube video and followed your instructions. IT WORKED 1st time. You are a star. Thankyou.
nevermind its redsnow right
whats the site to do it
can you get any thing when it is jail broken
does it work on an ipod touch 3g???
hi, i have a question, i am on base band 06.15.00 with firmware 3.1.3, can i update that firmware to 4.2.1 using redsnow jailbreak straight from 3.1.3 to 4.2.1???
does anyone know how to carrier unlock it with redsn0w?
Cydia doesn't open,what do you do now?
it says: done the rest of the process will take place on your device and then nothing happens
IT did the same steps as you did but that black screen with the write letters doesn't appear on my phone
Is this safe? Due to the older firmware. Will setting up a SSH root password be sufficient to secure your phone in this case? And after you've removed the jailbreak, will the level of security go back to normal or will there still be a sort of security gap because of the jailbreak (and which you will have to secure it yourself by a SSH root password or something like that)? Please help! Thanx in advance.
