Every time i try to download the firmware for my iphone (3g version 4.2.1) it downloads as a compressed file and when i get ready to jailbreak it and open redsn0w i cannot locate it bc its not saved onto my desktop. but when i download it as a compressed file, i do save it to my desktop…IM LOST PLEASE HELP
make sure the file extension is .IPSW
i download the zop file. extract it, there are no ipsw files. You say rename the extention, but what files to change
You change the ZIP file to a .IPSW file.
nswr the question please¡¡¡
Just Rename the .zip to .ipsw for example
2_4.2.1_8C148_Restore.zip then rename it like 2_4.2.1_8C148_Restore.ipsw thats all
yea if it is a zip file it is compressed and you need a program to unzip that
i have done all the steps ive even redownloaded the firmware twice and after i change it to ipsw it says unable to recognize specified ipsw what do i do im stuck
I tried changing from zip to ipsw for hours its a waste of time. then i downloaded firefox web browser and it does not zip files it downloads them as they are. in this case ipsw. it worked perfect.
TANK YOU FORFOR AIVR
changed file extension to .ipsw but when it unzipps it says some files could not be encrypted. then it doesnt give the little white ipod icon next to file. it still shows the yellow file
did you get it to work???

Open iTunes and connect the iPhone to your PC/Mac
Press and hold the Home button and the Sleep/Wake button at the same time.
After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode.
