[Q] Every 48 hours the data is blocked, no WiFi ni 3G - Galaxy S 4 Q&A, Help & Troubleshooting

Hello I have a mobile Samsung i9500 S4, every 48 hours the data is blocked, no WiFi or 3G. I have to power cycle the phone and restarted. This happens since upgrade to 5.0.1 from Kies.
I made a deleted data and cache. I reloaded the rom from Odin. The IMEI is correct.

Any idea?

Strange issue. You could try a custom rom or root and delete everything knox related.

[Q] Cannot surf on 3G/4G, but wifi works fine

Hi, i ran into a issue, i can't surf on 3G/4G mode, but while at home on wifi it works fine.
i have tried to reflash the firmware, but the problem remains.
My phone is a Swedish(tele2) unlock sm-n 9005
i am on kitkat poland rom XEO
i have check the apn settings, tried with France's and Germany's roms, but didnt help
i have also tried wipe factory/cache and dalvik this before flashing, but still cant connect..
my note is already at 0x1 so i dont have to worry about this.
any help will be appreciate..
Hi again
Just flashed the phone with N9005XXUENB7 (UK) with Re-partition + Nand erase all + Phone EFS Clear + auto-reboots + F.reset time
The phone went into UK firmware, but the download mode still says
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
and the wierd thing is, even i did a Phone EFS Clear, all the EFS info remains, but in the end my phone still cant surf on the 3G/4G
and the second wierd thing is, in about device> status, i see the phone have taking a ip adress from ISP..
i have spend all night here but still no clue how to fix this, maybe samsung service is my last chance, but knox 0x1
Silly question: did you check the APN settings?

[Q] Very slow mobile network search and registration

This is on a rooted I9505 with a custom AOSP ROM (C-ROM).
KNOX is 0x1
Baseband version: I9505XXUFNA1
Mobile carriers are 3 (Three/Drei) in Austria and T-Mobile in the US.
Network search after cold boot takes up to 5 minutes before it shows the available carriers and registration takes up to 2 minutes after selecting correct carrier. This is really annoying, especially after briefly losing network connection in the subway or an elevator.
It used to be a lot faster, but the phone needed to be carrier reset after bricking the EFI partition and clean installed with a Samsung ROM. Is this modem related or what else can you suggest to troubleshoot the situation and get back to normal?
TIA

[Q] your sim card does not allow a connection to this network galaxy s4

Hey all, just a few days ago my rooted Galaxy S4 SGH-i337m running KitKat 4.4.2 NE1 with Fido Canada suddenly said "Emergency Calls Only".
I rebooted it and it says :"your sim card does not allow a connection to this network". It has been working great for months until now. I have removed battery, sim card reset to factory, wiped cache and reloaded again. My sim card works fine in my Motorola RAZR, no problems whatsoever.
This is what I used with Odin:I337MVLUFNE1_I337MOYAFNE2_FMC. Still same issue. WiFi and everything else works just fine. APN is all fine also.
My S4 is not unlocked, just rooted ( but now it isnt after factory image reset.
Dunno what to do. I have even put a new Sim Card in but to no avail and it works also with my Motorola RAZR.
Any ideas??? Knox has been tripped so if I have to send it away, wonder how much it will cost?
Thanks
Kind of figured out that the NV/RUIM:SIM was messed up because my phone was picking up all the networks so it had to be something fairly simple. SO I downloaded Rogers KitKat from Firmware site ( so I thought ) and flashed it thru Odin 3.07. After it had finished and I had wiped my phone with Philz to load a new ROM I was shocked that it was Version 4.2.2!!!!
Now my connection is back, and the menu for unlocking the phone was all there so I did that while I was at it. Don't have another carriers Sim card to test it out but I followed instructions to a Tee and I am assuming that it worked.
Just have the WiFi/sound problems to deal with. I am ****ting car sized bricks as I thought you couldn't downgrade like that!!! I hope I can upgrade again as I had no problems with the 4.4.2.
Will search the Forums some more but in case anyone has the answer, please let me know as I am at work so time is limited.
Can I now load 4.4.2 Stock Fido Formware back onto my phone or will it totally screw up??? Knox was already tripped so I have nothing to lose

Mobile data problem after flashing 5.0.2 rom (A5 SM-A500H)

I recently purchashed a A5 (SM-500H) from a carrier (Claro) in my country and it came with stock 4.4.4. I decided to flash an official Samsung 5.0.2 update from Saudi Arabia, everything was working fine (I could make/receive calls, use wifi, etc) but then I tried to use mobile data and it shows the "H" and arrows you get when you're connected to mobile data but when I try to use internet it doesn't load anything.
I already tried to change the APN settings, but it still doesn't work. I tried almost every solution to similar problems but they didn't work neither.
My IMEI is still there if that matters.
What should I do? Should I just flash the 4.4.4. rom again?
Thank you so much!
Reset the phone 2 time it will be ok??
