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

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?

[Q] Kitkat problem with sgs4

Hi
Ever since I flashed a kitkat rom whether its TW or AOSP im having problems. I never had problems with jelly bean.
With Touchwiz I have the issue when rebooting, sometimes I do not get data and when I try to activate data i get a message "insert sim card" after a few reboots or now "hot reboot" i get the data back.
With AOSP which i tried recently, I have a problem when rebooting I cannot type the lockscreen code! I need a lock screen code for exchange emails.
Could it be the boot loader that is causing issues? I tried flashing official roms but does the one file i flash update the boot loader? Im not sure if I have updated it.
Anyone else similar?

I had problems with reboots when i had wrong baseband. What you can do is:
- Flash Stock Rom (TW)
- Dial *#1234# and attach what appears here.

My baseband says I9505XXUFNB9
Bootloader says I19505XXUFNC4 (root checker app)

I got the "no sim error" when I flashed back to Echoe rom for my i9505, all I did was reflash the rom (with no changes) and bingo worked as soon as the screen came on.

[Q] S4 Problem with network WCDMA (3g)

Hi all, I have a problem with 3g.
I bought s4 i9505 and it was on 4.2, I had problem with slow internet, so I called operator and they told me to turn on WCDMA only in settings..
When i turn WCDMA only on, it loose my network (emergency calls only), and i have no network at all.. when i put wcdma/gsm automaticly it has normal network..
So i thought its problem in firmware, so today i fleshed 4.4.2 with odin.
Now i have same problem, no network with wcdma only..
I serached internet and i tried several programs for 3g, but nothing worked.. any solution ? thx

Some problems can appears:
1. Type *#1234# and paste here what appears. Continue with the step 2 if you have wrong CSC.
2. Wrong CSC. Solution: Install Kies 3 for know ur CSC (pic 1). Go to Sammobile.com and download the correct firmware 4.4.2 (correct region) for your device.
3. Flash again this firmware and let the process finish till the final. Dial again *#1234# and verify if all is correct like the firmware you downloaded and installed before. Flash again same firmware if not.

Might be a corrupted EFS folder.
I have had the same problem for 3 weeks now. I've tried searching for a solution here and in other online sites to no avail. I personally tried flashing a new stock rom, flashed some odd number of modems, tried factory resetting etc. Nothing worked. I'm afraid it might be due to corrupted EFS folder which I still don't know how to repair.

Hey, I have the same problem, I guess that there's not solution yet.

Do you a have a efs.img backup ? Or any kind of IMEI/EFS/RADIO backup ?
I had the same problem I flashed the stock ROM and somehow I lost my IMEI info, I tried everything and I was even thinking about buying a z3x box but then I decided to do a very risky move , I completely deleted all the EFS related files/info and reflashed again but now I was not able to boot because I always sent me to recovery mode saying that :
"E:Failed To Mount /EFS (invalid argument )"
Then all I did was installing TWRP and rooted my SM-G935F and then I placed my efs.img backup on my internal SD CARD and went on recovery launched the terminal and wrote this :
dd if=/sdcard/efs.img of=/dev/block/platform/155a0000.ufs/by-name/EFS
Then I wrote reboot and it finally my phone was booting and I recovered my IMEI and was able to use my phone normally.
This only works if you have a backup of your EFS, and even if you do is risky , but I did it because I lost all hope and was accepting the fact that my phone would just become a useless wifi only device .

So there is not a fix yet for this problem ?

I have a problem on my s7edge instead. If i have valid imei i'am almost always in emergency calls, and when the signal comes back does not go into mobile data connection. With the wi fi no problem.Can someone help me i'am going crazy.!

IMEI, Network Signal and Baseband is misssing

IMEI, Network Signal and Baseband is misssing
Hi
I am ready to donate if any expert can help me to restore IMEI.
I am using SM-N9500 samsung note 8 model - hongkong version, i frequently change the roms.. when last time i tried to install a custom rom i lost IMEI. i am getting error like IMEI-unknown, baseband- unknown, no network and sim cards not working..
i tried installing stock rom, custom roms, it was installing successfully but only baseband, signal and IMEI are not working. i didnt even back up my EFS folder. So, kindly help me to get back my IMEI.
I have installed stock rom, still no IMEI. now i rooted my mobile and taken EFS backup. is it enough? if yes, pls suggest me the next steps. I also tried installing combination firmware, though is not working, installation was successful and also i am able to see the factory binary logo, after which it will switch off automatically and boot loops. everytime it will open factory binary and immediately it will switch off automatically..
Build number - R16NW.N9500ZHS4CRJ1
