Downgrade BB 04_05_04_G (works!!)

[EvilGonzo]

So, I did everyyyy tutorial i found on the net on how to downgrade from 2.0 to 1.1.4 again...

After 2 days of work i found out what my problem was, and why i couldn't erase/downgrade the BB 04_05_04_G, the trick was to "jailbreak" the phone (i used iliberty+) before running the patched ziphone. Then restored back the original fw 1.1.4 with itunes and used winpwn to upload the custom fw.

** You need to get write access in order to get “patched ziphone” working, that’s why the trick is to “jailbreak” BEFORE you run it.**

Cheeerrss!!

This set of instructions worked for me...

Steps I did:

Step 1) You need to uninstall iTunes 7.7 and install iTunes 7.5 or 7.6.

Step 2) Now that you have iTunes 7.5/7.6, put your phone into DFU mode.

Step 3) Restore using iTunes 7.5/7.6. You will get an error like 1011, 1012, 1013, 1015 this is normal. Errors 1601, 1602, 1600 or anything else are not ok.

Step 4) Once you get the error above, leave iTunes open and kick your phone out of restore mode. I recommend iLiberty+

Step 5) Now use iLiberty+ (or any) to Jailbreak the phone and then run the patched ziphone version, just use "downgrade" and "debug". After this you should have your phone ready without the 04.05.04_G BB.

Step 6) Restore using iTunes 7.5/7.6 to the original 1.1.4. Done, your iphone was restored to factory defaults, now use winpwn or the flavor you like to get your custom firmware, and you'll see that the bootneuter now is working!!! no more Error 5.

hope this helps!!
