Experts please help: iphone 4 in recovery mode loop

[cortex1924]

Hi Guys,

I have an iPhone 4 (first generation) and running on iOS4.1, baseband 2.10.4, using a Geveysim and NO shsh saved at all.

I wanted to update to a newer version of iOS while keeping the same version of the baseband (No_BB).
So I tried with Snowbreeze but itunes always returns errors such as 3194, 160x, 11 ... I used an SSL server with TinyUmbrella but still no solution.
So ultimately, I used redsnow (latest version) to restore it. And as I can save only a SHSH for the iOS version 6.1.2 so I proceeded to restore iOS 6.1.2.
Redsnow did a good job and update went well but when reboot the iPhone gets in recovery mode loop always.
I used TU, iREB but to no avail. Still in recovery mode.
Do you have any ideas how I can do now to run it again?

Thanks in advance,
Sep

first try this video guide:

if it does not work, since apple is still signing 4.1, restore back to 4.1 by creating a custom stitched firmware with redsn0w, then restore..

let us know what happens

My iPhone is stucked at recovery mode loop. I can't do a restore from iTunes as I have to keep my BB.
And as I said, I don't have any saved shsh file before

Without previous shsh blob, you can only restore to 6.1.2 . In order to preserve baseband, put iPhone into pwned dfu mode and restore to custom firmware of 6.1.2 created by snow breeze or redsn0w
