So, i need to create a custom ISPW from Snowbreeze 2.5.1 right? the one i make in 2.5 is no use?
Yep! Always use the latest version of Sn0wbreeze!
Oh I believe you.
I just think it's kinda strange that Sn0wbreeze is supposed to be able to upgrade to BB 6.15 when in fact it isn't...
Yeah, i notified the developer about this issue. Hopefully he will fix it on Sn0wbreeze 2.5.1
I can confirm the error has been fixed in Sn0wbreeze 2.5.1
Just downloaded sn0wbreeze 2.5 and I'm also getting the 1002 error. I expected it to be solved but it obviously isn't...
Just use baseband preservation mode and restore custom IPSW. Once done, jailbreak with Redsn0w. Believe me it works!
"Here is the solution which worked for me." is for 4.2.1...not for 4.3.1
ps: if u have shsh blobs than it will work with the link...otherwise not yet
Yea, you need to downgrade to iOS 4.2.1 to upgrade to iPad baseband and for that, you must have iOS 4.2.1 SHSH blobs!
This method does not WORK with my 3GS. In Final step iTunes reports an error 1002. This is another fake article!
Dude error 1002 means hardware failure. Nothing wrong with article. Hope it helps!
No it doesn't have anything to do with hardware. I am getting 1002 error as well. For some reason it doesn't update the baseband to 06.15.00
I believe there is something not working with snowbreeze. It restores up to 95% and then ends in error 1002. After that the iPhone remains in restore (not DFU) mode (displaying the iTunes-logo and the cable).
I have tried iReb to kick it out of the boot loop. Doesn't work.
It does restore to stock 4.3.1 without any problems. That means hardware is ok. (I have unlocked alot of iphones, I am not new to this.) Does anyone have a solutions for this 1002 error?
Thankyou Marcel for confirming this. After restoring my friend's iPhone 3GS (Baseband 05.16.02) with custom IPSW made with Sn0wbreeze, i also got error 1002. This is definitely issue with Sn0wbreeze. I downgraded back to stock iOS 4.2.1 (SHSH saved) and tried Redsn0w, it worked like charm!
same here 3gs error 1002
have to restore to stock 4.3.1 baseband still 5.16.02
so sn0wbreeze cant update baseband like it claimed!
Here is the solution which worked for me.
[SOLVED] Windows OS needs .NET framwork 2.x in order to run Sn0wbreeze
Has anyone had trouble running Sn0wbreeze 4.2b1? I keep getting “Application Error” even after reboot.
Sn0wbreeze-v2.4b1.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
Install latest .NET frame work (v4.0) from Microsoft website. Its the Windows error (NOT Sn0wbreeze), so changing the PC will definitely solve the issue.
