3GS - 4.3.3. will only boot tethered or sit in DFU Mode

[pearsth]

I used Redsn0w rc16, and put on the 6.15 baseband to unlock. all was well. then, I used jailbreakme.com to install cydia. it crapped out during the install of cydia and it would not work.

To remedy that, I used Redsn0w rc16 again with the "cydia install" option checked and all seemed well. Something then happened to cydia so I tried to reinstall again using Redsn0w, and now I am stuck in a mode where I can only boot tethered via Redsn0w.

I used snowbreeze to create a custom ipsw for 4.3.3 with cydia included. It installs fine on my iphone with itunes (with appropriate use of iREB and TinyUmbrella). However, it never ends up booting. It just sits in DFU mode again and again unless I boot tethered with Redsnow.

Any help would be greatly appreciated.

what version of snowbreeze did you use ?

[pearsth]

2.7.3

When you build your custom fw, how did you answer your bootrom , new or old and do you know if your bootrom is new or old .

[pearsth]

Snowbreeze checked and said I had the new bootrom, so that is what I used (redsnow also gave me an error and stopped when i picked old and tried it the first time).

More info
Windows 7 64 bit
I am running the apps using shortcuts for running as administrator and windows xp sp3 mode

Do you have a pc that runs only 32 bits, if you do try it out.
Redsnow giving error , try set affinity to one.

I did try a windows xp machine...i'll give it another go. Should I just try to restore my sn0wbreeze using itunes are do a bunch of stuff over again?

[iYeow]

If you need to upgrade iTunes, version 10.1 is good enough for 4.3.3. Just restore to the same custom firmware you created.

[pearsth]

I am on itunes 10.4.0.80 (latest)

[iYeow]

Then, that is fine.

You have to download your 4.3.3 blob onto the other pc

OK - I tried it on an XP machine running 32 bit SP3. The following didn't work - (I tried in this order):

1 - Boot tethered, use Itunes to flash custom IPSW from Snowbreeze, got error, then put in DFU with Redsnow and Itunes flashed it - stayed in DFU when done
2 - Use Redsnow again, nothing checked - stayed in DFU when done
3 - Use Redsnow again, install cydia and new baseband checked - stayed in DFU when done

In the process of creating another custom ipsw with snowbreeze on XP and will try to load with itunes when done. Will keep you posted.

Just tried the last step with custom ipsw and snowbreeze on XP with itunes. No go..after it was done, I got the dissapointing disconnect/reconnect USB sound with no boot up on the phone. Now I am really stumped. The XP machine I am using had no problems with my iphone 3G.

I really think I hosed something up deep inside the phone in all my iterations of this. By the way, I used the "simple" option with snowbreeze.

ok , apple is signing 4.1 firmware . Now I want you to restore to stock 4.1 firmware, let apple verify your 4.1 blob meaning set hosts file pointing towards apple server. If you can get it back to booting status at home screen then you don't have to remove the battery to reset the iPhone.

[pearsth]

We are getting closer, it seems.

Now, I am on the USB/CD Itunes logo screen and itunes got error 1015.

If this thing can just boot now into 4.1 and be unlocked and jailbroken, I will be happy with that.

What should I do next?

Thanks so much for your help thus far!

Tom

I used iREB recovery loop fixer popped in an old AT&T (not active) SIM and connected with itunes. The phone is working again.

Not sure what state I am in now. Since I have firmware 6.15 am I unlocked for any SIM? Also, what is a next step to put on Cydia?

THANKS!!!!!!!!!!!!!!!!!!!

Install ultrasnow from cydia to unlock.

You should now be at 4.1 with iPad baseband.

Exit recovery can kick out error 1015 even you have iPad bb.

Oh, lime rain to Jailbreak at 4.1

[pearsth]

I am all set...thanks.
