woooooooww i got it, finally. It worked. SNOWBREEZE baby, that did it! You need to set up a custom ipsw and do not select the Hactivate check box. That is what gives you the problem with NO Cell. I had to do it 2 times because the first time I checked it and i ended up with the problem problem. Thats it. Worked great, no problems. Very happy with it now. This jailbreak works great. Recovery43 did not work, missing that file the other guy said. Lotta stuff on the forums did not work.
 
Thank you, Oakland6980.

Disclosure: only experience I've had jailbreaking etc. was 4.2.1 (IIRC) on a 3GS. Went swimmingly. iPhone 4 on 4.3.5? Not so fun. ...I'll spare you all on the last 6 hours of my miserable life.

I followed the instructions you posted, in an attempt to downgrade from 4.3.5 to 4.3.3. Everything went well (iREMv4 did what Sn0wbreeze 2.7.3's iREB apparently was failing to do the past 6 hours FTR).

During the 1013 Fix, Step 5, at the following moment, "fixrecovery writes some stuff to a DOS window...
Once done, the iPhone reboot and Apple logo appears, followed by a progress bar for a short time, then the iPhone is running as normal and detected by iTunes which can activate, and restore
."

Not so for me. :(

My iPhone grayscreened (no image but backlight on) for maybe up to 5 seconds, then black screened, no boot and I got nothing at this point. Does not respond to power or Power+Home.

iTunes DOES detect it's in Recovery Mode, fortunately, but I'm lost for my next step. If anyone has any experience in my shoes by all means chime in/PM me. :eek:

For disclosure, after restarting iTunes (IDK why I decided to do that) I Shift+Restore'd in iTunes, pointing to the native Apple 4.3.3 but it gave an Error 1600 as I half-expected.

I then tried to Shift+Restore to a Sn0wbreeze-generated 4.3.3 IPSW I made in the past. Error 1600, again.

So here I (finally) wondered if it was in DFU or pwned DFU mode, since it takes two 1600's for my mind to function, and re-ran iREB v4. iREB v4 generated a .NET Framework error until I closed iTunes FTR. I then, again, attempted to Shift+Restore to the native Apple 4.3.3 IPSW. As I (eventually) surmised yes it was in normal DFU Mode, not pwned DFU, as it attempted to reflash to the native 4.3.3. Again.

So I get back to Error 1013, as expected. This time I wonder about two things when I read, "Put the iPhone in DFU mode again." & "You must have internet connection at this point because fixrecovery download some stuff from Apple."...
1) DFU or PWNED DFU?
2) Internet to Apple: I wonder if TSS Server of TinyUmbrella is interfering?

So here I re-pwned this iPhone's DFU and stopped the TSS Server of TU.

When I ran FixRecover43 I noticed its first few lines said:
Initializing libpois0n
ERROR: The process "iTunes.exe" not found.
ERROR: The process "iTunesHelper.exe" not found.
Waiting for device to enter DFU mode
Found device in DFU mode​
So apparently FixRecover43 is wanting iTunes to be running, and it apparently accepted the phone running in PWNED DFU Mode.

Problem persisted. I'm back to the top, "Once done, the iPhone reboot and Apple logo appears, followed by a progress bar for a short time, then the iPhone is running as normal and detected by iTunes which can activate, and restore" <-- Did Not Happen. :(
 
I ended up using iFaith 1.2.1 (1.3.2 would NOT complete for me, IDK why not) to generate 4.3.3 blobs, but then ironically needed to use iFaith 1.3.2 to create a signed IPSW (1.2.1's IPSW's in both methods would not restore) and then I could get the device back to 4.3.3 proper. Sheesh.

Now to figure out how to jailbreak 4.3.3.
