Post [Q] Help!!! ATT S4 I337 MK2 firmware upgrade Safestrap 4.4.2 without SIM card

Hello everyone
I come from China , and has a U.S. AT & T 's Samsung S4 (SGH-I337)
It has been unlocked, in my country can use China Mobile and China Unicom SIM card

I now use the official version of the MK2 4.3 ROM, I want to upgrade it to 4.4
And the use ib4stid SSGE-i337-XXUFNC9 the 4.4.2 ROM and ViSiON X GS4 4.4.2 XXUFND7 ROM

I would MK2 ROOT, then install Safestrap-JFLTEATT-3.71, perform the purge data operation
Then install this ROM 4.4.2-SSGE-i337-XXUFNC9 of
Written mldmodules, as well as the MLD AP CP BL three documents
Normal system start it, but did not detect SIM phone prompts
( Using China Unicom's SIM card , upgrade steps without error, I'm sure IMEI and EFS normal)



I follow this method of operating
http://forum.xda-developers.com/showthread.php?p=51067706

Because the MK2 system, so he referred to the use of MLD modules
MLD of AP, CP.BL three documents

Version 2 is for those that DID NOT take the NB1 update, and are still on a full MK2

Downloads

MLD/MK2-safestrap kit- http://d-h.st/LyA

Download all files, and extract them somewhere on your desktop.

Safestrap 3.72-- http://forum.xda-developers.com/show...php?p=45693712

Download a pre-rooted 4.4.2 rom (SEE POST #2 FOR COMPATIBLE ROMS and place on your external sd.

Reboot into SS, and wipe all except external sd. Install your pre-rooted 4.4.2 rom, and flash mld modules. Tap "Home". Enter reboot menu, and choose download.

Now open Odin on your pc, and add the MLD tar files ap>>ap bl>>bl cp>>cp. Hit start. Once finished, it will reboot, You should now boot into a rooted 4.4.2 KK rom.

NOTE- Once 4.4.2 is installed, download Safestrap 3.72. Install and open. Uninstall recovery, and then install recovery. Your SS is now compatible with 4.4.2. The only time you will need the mk2 files beyond this is when reverting to an mk2 system.

If you are already on an existing 4.4.2 rom, then uninstall 3.71 Safestrap app, and install 3.72 beta. Open, uninstall recovery, and then install recovery. Safestrap is now updated on your system.



The strange thing is :
To view the phone status in the device status , I see the phone has been identified to my SIM card and connect to the
China Unicom H + 3G network , but does not detect my phone number

But the phone can not make calls, there is no data network
Wait a minute it prompted no SIM
Please restart the device

When I returned again ATT official MK2 4.3
Phone is working properly , you can make calls and internet access

Please help me to solve this question, I want to use 4.4.2 ROM

My English is not good, I hope to get your help
Best wishes

So...in the settings? Excuse me if I must use english, 在设置里面?

And it recognizes the SIM and displays as connected to HSPA+, but doesn't show a number?

Can't really make sense of this part. The phone can't make calls, that can be understood; but when you say "There is no data network", do you mean that it shows that there is, just that you can't connect, or does it display as disconnected?

Phone settings - status - it shows open network
I hit the mobile data switch, but it is not connected to the Internet
Can not make a call
