iPhone 6.1.2 issues

Hey guys, so I just restored my iPhone 4 to iOS 6.1.2. I tried to jailbreak with redsn0w, using the 6.0 ipsw, because the 6.1.2 wasn't recognized, and I was recommended to use the 6.0 ipsw. Although my iphone is still thetered, it boots without the need to connect it to my computer.
However, Cydia does not work (it closes immediately) and I can't get any service. What should I do?
Any help will be greatly appreciated.

EDIT: , I unthetered jailbroke my iphone using evasi0n, however, I get NO SERVICE.

Restore to 6.1.2, use evasi0n to Jailbreak.

redsn0w says that it doesn't recognize the IPSW but I can continue.
Is this a problem?

You can also boot tethered using redsn0w, open Cydia and search for evasi0n there. This way it will only install the evasi0n untether.

As I stated in the original post, my iphone boots without the need to use redsn0w and Cydia doesn't open.

I just restored my iPhone with 6.1.2. Now it's in recovery mode and evasi0n doesn't recognize it. Any suggestion?

If I recall correctly evasi0n does not work with phones in recovery mode. After you restored your phone, simply make sure it's power on as normal (not in Recovery or DFU Mode) and use evasi0n.

I can't get out of the recovery mode state unless I jailbreak it.

Tethered jailbreak phones boot into an un-jailbroken state if not booted using the Just Boot tethered method.

----------





Plug your phone phone into iTunes, close every other program
Click the restore button, choose set up as new
As soon as you activate the phone, use evasi0n.com to jailbreak.

How can I restore it with iTunes while preserving the baseband? I was just restoring with redsn0w because I need to preserve the baseband.

dhlizard said:

Nice of you to finally mention you need to preserve baseband

Both Redsn0w and TinyUmbrella have a fix recovery feature
Use newest Sn0wbreeze to do a No BB restore to iOS6

Sorry! I already tried to get out of recovery mode both with redsn0w and tiny umbrella but it didn't work.So I create a custom 6.1.2 IPSW with sn0wbreeze (using the simple method), then Shift+Restore with iTunes to restore and then jailbreak with evasi0n right?

dhlizard said:

Yes

And does the newest iTunes allow me to load custom IPSW's or do I need to download an older version?

dhlizard said:

Newest should be fine

Thank you very much! Just one more thing, in sn0wbreeze, should I create a custom IPSW using the Simple Mode or the Baseband Preservation Mode? I ask because the Simple Mode also jailbreaks the device.

Newest should be fine

Just so you know, if you are preserving 1.59.xx, many are having issues getting Ultrasn0w to unlock it on iOS6.
And if you are preserving 2.10.xx-4.10.xx, many sim interposers do not work on iOS6.

My baseband is 03.10.01. I currently use the carrier to which my iphone is locked too, I just want to preserve the baseband in case someday I need to unlock my iPhone to other carriers.

dhlizard said:

I don't use Sn0wbreeze (every phone I own has always been IMEI unlocked).
From what I read, simple mode should work just fine.

If you need step by step help, use Google or go to the developer's website (iH8Sn0w) for more info

Oh ok. I think I'll go with the baseband preservation one, because it also jailbreaks the iphone, and so it may conflict with evasi0n.

Thank you all for all your support.

dhlizard said:

It will not conflict with evasi0n, the only iOS6 jailbreak is evasi0n, so Sn0wbreeze is using that method to jailbreak also.

And will it jailbreak it unthetered?
I ask because evasi0n says it is not recommended to jailbreak an already jailbroken device.

Here is a tutorial for Sn0wbreeze as I recommended you Google/find/follow earlier

http://www.idownloadblog.com/2012/11/12/how-to-jailbreak-ios-6-and-ios-6-0-1-with-sn0wbreeze-2-9-7/

Sn0wbreeze has been updated for 6.1.2 since the tutorial was written but the steps should be the same.

Good luck - Done here

I have done everything, but when I try to restore it using iTunes, it gives me the 1600 error. I ended up restoring using redsn0w and jailbreaking using redsn0w also.

Everything is working fine now, except for the fact that I have no service. Any suggestions?
