Mobile data is not available or invalid SIM on unlocked SGH-i747

Hey, people!
I have an unlocked SGH-i747 I got last week. Today I tried to enable USB tethering, but I got the message "Mobile data is not available or invalid SIM"; same thing happens if I try to enable Portable Wi-Fi hotspot.
¿Any solution to this? I know I will probably have to root the phone, that's no problem.
Thanks!

Bone stock? You got to pay for it stock. Flash a custom ROM, it should work.

Yeah; I didn't know AT&T does that for tethering. I just flashed a modified stock ROM with the tether fix and that worked out pretty well.
Thanks!

Which ROM

I have same problem.. Please help me to do this

I have AT&T device, rooted and unlocked on another provider; also build-in tether does not work.
But it is working over 3rd party free (donate) application "Wifi tether" for rooted devices.
EDIT:
I double checked now, and it does not transmit any data over "Wifi tether" application. Sorry, it does not work....

How do you do flashing of the SGH I747

How do I do the flashing and which modified stock ROM with the tether fix did you use? I would appreciate your help. Having the same tethering problem.

Guys, please, do your homework.

Okay, so the question I have for OP is -- do you have network data turned on?
"Mobile data is not available" << means that data is turned off. Turn data on, then try to enable hot spot, then that should work.
http://www.marksatterfield.com

Mark, are you serious?? Of course I have network data turned on! Why would one try to share a disabled connection?
And always remember to read the whole message: "Mobile data is not available OR invalid SIM."

Have you guys tried pdanet? I've used it on stock and haven't had an issue with it.

I have the same issue, get the no mobile data or invalid sim with the built in feature. Tried different 3rd party apps and I get the same message with those. Tried the tether unlocker and that didn't work either. Even did the tethering provision file replacement and it still does the same thing. Contacted Rogers and I have tethering feature. My phone is a AT&T GS4 unlocked.

Please be careful in flashing... thanks for enewman17 ive successfully enable my wifi tether..

I have successfully enable wifi tethering in AT&T SGH-I747 by flashing modified framework-res.apk. It is for Android 4.4.2

I flashed my Samsung Galaxy S3 AT&T SGH-I747 and Wifi Tethering is working fine.
This is for AT&T SGH-I747 with Android 4.4.2 and with Baseband Version i747UCUFNJ1.
Download it. Once download you need to flash using any custom recovery.
Though it is not required but it is always advised to take complete backup of the device. Also, you need to try at your own risk. If you brick the phone, I won't be responsible. I flashed my phone and everything looks good.
Feel free to donate if it help.

Any of the procedures linked in this post will work for you http://forum.xda-developers.com/showpost.php?p=39415390&postcount=5
If you plan on unlocking the bootloader do that first and the unlocked bootloader process is much simpler.

I use this works perfect.

I have a request for you if you dont mind. If you still havent flashed a different firmware and are still running the Rogers one on your ZL, can you tell me if you get an error when enabling "Portable Wi-Fi hotspot". The error should be "Error occured during tethering".
I got the Rogers phone also but flashed it the first day I got it with the generic firmware 10.1.A.1.434. I never bothered checking if tethering was working in the first place. Anyway, I flashed it back to build 395 but the same thing happens so I flashed it back to 434 and unable to tether. Everything works fine apart from that.
Thanks!!

Hi Crash, I can confirm that on my Xperia ZL(Rogers), Portable Wi-Fi Tethering works, i received no Error; connected a device to the Wi-Fi hotspot just to be sure it does in fact work.

Thanks KayEx ... I actually figured it out. I configured the right APN manually but Rogers was also pushing something called Rogers Tethering which couldn't be selected but by modifying it's value from isp.apn to ltemobile.apn, the problem dissapeared.
It's all perfect now! :good:

[Q] Help with L35H

Hello,
I recently tried to update my Xperia ZL L35H (purchased in China) to the latest 10.3.A.0.423 firmware. I chose the C6502 variant because it seemed that this was the same model with some regional variations. All worked well, until I tested the mobile data connection, which was non-existent. Considering that both L35H and C6502 both use HSPA, this incompatibility with the C6502 firmware was surprising. I even used the AOKP ROM for awhile and had no issues with data connectivity.
What's worse, I had my CWM backups on internal storage. My bad, I know. Updating to the 10.3.A.0.423 erased my internal storage, so, no more stock firmware backups.
I would be most grateful if some one could help me either:
*Help me find a L35H firmware, or
*Help me troubleshoot the data connection on the C6502 10.3.A.0.423 firmware.

L35h
Glad to see someone else has the L35h. I'm afraid I can't help you with your problem, but I was wondering if you were able to root it, and how?
I rooted mine with Bin4ry's script, but then made the mistake of upgrading, not knowing that it would remove the root. (I'm completely new to Android and had no idea that the phone would come with a bastardized version of Android that doesn't even allow a Google account to be on it, without rooting.) Now I'm on 10.1.1.A.1.253, but none of the rooting scripts will root it now.

I rooted the 253 using :
http://www.droidkube.com/how-to-root-sony-xperia-zl-and-install-cwm-recovery/
Then lost root after updating to 10.3.A.0.423. I rooted that using:
http://forum.xda-developers.com/showthread.php?p=43288981

Thanks, I might have to do it this way ultimately. I'm afraid of destroying my phone completely, but maybe it's the only way I'll be able to do it.

Maybe you could help me out here. What 253 variant did you use? Does everything work on it? What shows for "Model Number" under "About Phone" in settings? Could you post a download link for me?

I got it to work. I'm currently using the C6503, but the C6502 might have worked as well.
The key in to go into Settings/Xperia and click on "Internet settings". Afetr a brief download, my 3G data was back!
Everything appears to be working fine! No more L35H!

Where did you get the 10.3.A.0.423 firmware? I've decided I'm going to use Flashtool and just go for it. Would be nice to say zaijian to L35h.

Instructions here
Downloads here
You have to register and log in to activate the download link on the xperiablog page. Both the C6503 and the C6502 worked for me. Supposedly, the C6503 adds LTE support, but I don't know if there's a hardware difference to reflect that. I've been using this firmmware for a week now, and it's been flawless.
Also, check out Doomlord's easy rooting toolkit (for root) and XZDualRecovery (for CWM and TWRP) here on XDA, both of which work flawlessly on this firmware as tested on my device.
Check out my post on this page if you're disappointed with the stock sound volume limitation.
And don't forget the "thanks" button if you appreciate my help

Thanks so much! Which country firmware did you use? I was wondering if I should go with Germany, Indonesia, or US.

I'd go with whichever one matches where you're at. I'd have to look it up to know for sure. Both the Indonesia and the MEA (Middle East?) ones worked on mine, and I'm in China. Some locations use the same bands, others don't. I'm no expert in how that works. I might be wrong here, but I think the Settings/Xperia/Internet Settings auto-patch takes care of that for you. My 3G (or any data connection) didn't work until I took care of that.

I'm in China as well, so I'll go with the Indonesia one too, especially since I know it worked for you. Thanks again for the help!

It worked! Took a while to figure out the drivers and stuff, but it flashed easily and now I have a non-bastardized, non-Chinese phone. Seems to run faster and smoother too. Great to say goodbye to the L35h and hello to the C6502!

Haven't noticed any problem like that. Or any real problems. Maybe the notification/SMS sounds are a bit wonky, but nothing that's really bothered me or is especially noticeable. Am still getting notices about how "this version of Android doesn't allow in-app payments" or something like that. I expected those to go away. But maybe it's just because I'm in China with a China Mobile SIM.

Hi Guys! I too brought sony xperia L35H from china....and would like to flash the MEA C6503 version. I installed the flash tool and made the FTF file ready. while just to make sure everything is alright i connected my phone and opened the flash tool. It says "device connected with USB debugging off", although i have enabled usb debugging in my phone. Do i have to install the adb as well or am i missing something. Any help is highly appreciated! Thanks

I think you have flashed a modded stock rom, that is the reason you do not have that option.

I'm also in the same situation. How to get OTA in this scenario?

just a flash the twrp or cwm backup of the update. it can be found on the forums

You could try this app - http://pdanet.co/android/ (available in google play store, but may be blocked by Sprint and AT&T.)
Also works on non-rooted phones!
The only downside is you'll need to pay a one-off fee for the full version unlock key.

I have tried pdanet+ and foxfi before, it doesn't work on Sprint.
I am looking for a way to do it with root access.

Not sure how Sprint detects tethering, but there are a lot of different tethering workarounds out there, maybe one will work for you. Get an Sqlite editor, and navigate to /data/data/com.android.providers.telephony/telephony.db and click on "carriers" and "carriers_cache", screenshot each, and post them here. I found a way to make it work on T-Mobile, might work for Sprint too.

It just always worked for me, maybe try dirty flashing the ROM and wiping both caches and see if it helps.

Tethering
Hmm...do you have Android 5.0 or 5.1?? I wonder if that has anything to do with it. I recently updated via ota update and then rooted my phone.

Using LeeDroid here with no luck, devices can connect to my hotspot but no internet

i too hAD that problem on sprint m9 unlocked,please help me

HTC one m9 rooted, S-off, Verizon, CM13.
Have an HTC one m9 himawl, that is rooted and also S-Off and has TWRP custom recovery. I'm running CM-13. Initially after I flashed custom recovery and CM-13 (after S-Off ing) my GPS did not work. So I reflashed back to stock, enabled GPS, then reflashed custom recovery and cm13 and my GPS worked. Alright so I had a similar issue with my screen casting, I followed the same method of flashing to stock, then enabling everything I could think, then reflashed to CM. That seemed to work. Now however I want to get WIFI hotspot to work but it will not. I can enable hotspot on CM13, people can connect to my hotspot, but no data is flowing through to the devices connected. Any help appreciated. Again this is HTC One M9 for Verizon that is S-Off and rooted. Thanks in advance.
