Recovery Loop, iPhone 3GS, 4.3.5

[cannella]

Hi,
I have a problem and I've tried, like, everything to solve it, but nothing works...
I have an iPhone 3GS on firmware 4.3.5. I tried to restore it but I got an error 1015. And so from that moment on I am stuck in recovery mode.
I tried to kick it out of recovery mode with several tools: iRecovery, RecBoot, iREB, fixrecovery, TinyUmbrella, Recovery Mode Toolbar, iPhoneRecoveryFix...
Nothing works...
Do you know how to fix this?

Put iphone into dfu mode and downgrade to stock 4.1, exit recovery can kick out error 1015.

[cannella]

I've searched for exit recovery, but I just can't find it...

[iYeow]

Exit recovery is from Tiny Umbrella.

[cannella]

yeah, that's what I thought. It doesn't work. iPhone is still in recovery mode.

[iYeow]

Are you getting error 1015, use redsn0w 0.9.9b1 to kick it out, only 4.1 can be kicked out if you have ipad bb.

[cannella]

Still no luck. Now I have a black screen...
I am getting 1015.

When you restore to 4.1, don't use tss server. Run tiny umbrella and set your hosts file pointing to apple server under adv tab.
Let your 4.1 restore verify with apple, error 1015 will pop up because your bb does not match your firmware but should be able to kick it out with Exit recovery.

Always use the latest version of TU

Thanks, it worked!
You are THE BEST!

Go to setting , general and about : modem firmware should be 6.15.xx. You can install ultrasnow to unlock.

By the way, you can jailbreak it with Limera1n at 4.1 for 3gs.

[cannella]

thank you.
Just one more question: Will I be able to have 4.3.5 firmware on it again?

[iYeow]

No, unless there is a tool to create custom firmware. If you have 4.3.3 blob, you can create a custom firmware of 4.3.3 from Snowbreeze 2.7.3.
Now your iphone is bootable, request shsh blob from tiny umbrella to see if you have any blob .
