[Q] Help please! KLTE unlocked rooted on stock fw. Neither SIM can access network

Hi guys,
I think I was messing around where I shouldn't have been and now I have 2 SIMs from 2 different providers down on my unlocked rooted W8. I had moved it back to XtreStoLite successfully and then for some reason I started exploring service codes and I think thats where I killed it. I've completely formatted both drives and reinstalled factory but I'm still getting the same result. The Bell SIM just says Emergency Calls only and then you go into the networking area and it says Insert SIM for network services. The Koodo SIM gets a totally different result as its getting the PUK-locked.
Any wonderful ideas?
Thanks a million.
Tony

Estrongs and CSC folder attached in zip format
Does anyone have any ideas on this? I got the PUK-Unlocked taken care of on one SIM only to end up with the same problems on both SIMs. The SIMs still show as unlocked as per CSC but the status is LIMITED.
I think what I need to do is blow away the CSC so any remaining tainted records are gone.... somehow without breaking the unlock. I guess this doesn't get wiped even when I'm in PHILS and highlighting and formatting everything and then reinstalling factory firmware from SAMMOBILE. I've tried updating Bootloader, Modem and then firmwares several times. I've been to the shop that unlocked my phone and they say well if its not asking for a code its still unlocked. I've talked to the PUK detective at Koodo. I've been to the Bell store only to be sent out the door in a rude manner.
I think what I need to do is reset part of the service code that contains SIM stuff.
Any guru can help me PLEASE???
Below is more descriptive info with screenshots of the issue and my troubleshooting.
Thanks,
Tony

@AltaEgo
Not sure why did you attached the Estrongs folder?
Did you try to flash stock firmware? Are your IMEI and baseband still valid?
And please check the following:
open Dialer, enter *#0011#, Menu, Back item, Menu, Key Input, enter Q0 and OK, wait for some seconds until you get MAIN MENU. Then select DEBUG SCREEN > NAS INFORMATION > MM INFORMATION > capture this screenshot. And then Menu, Back item, MM REJECT CAUSE and also capture screenshot.
Can you show these 2 screenshots?

Hi vndnguyen,
My IMEI LOOKS ok and my baseband does too but I'm just look at the About Phone>Status .
I'm not sure why I put the estrongs folder in there. Sorry, I was up for many hours straight trying to fix this. I used your Samsung Info folder to try many different codes with no luck. In this situation, you get the no sim error when you try to put a service code in the dialer so its necessary to root the phone and launch them your app. It seeps for whatever reason that the SIM is deregistered and almost not seen at all. One SIM I can get a little bit further than the other. I have tried restoring two different firmwares from Sammobile and also one with Kies, but NO LUCK.
I really hope you can help. I'll be so grateful. Even the provider wasn't helpful.
Thanks very much for your assistance.
Tony

According to the screenshots, the problem was that the network consider your phone as a illegal device. The network refuses service either because an ID of your device is not acceptable, or because the device does not pass the authentication check.
So please check:
1- Put your SIM card into another phone to make sure it works fine?
2- Make sure your phone's IMEI is not blacklisted?

Thank you. This is very confusing as I got my S5 as new. I spent another 40 minutes with Bell on the phone tonight and they certainly didn't mention anything of the sort. I'll try these and then get back to you.
Thanks!
Tony

Well I've tried reinstalling stock and complying with Knox with no luck. I've tried completely blowing away everything to do with Knox after wiping EVERYTHING and reinstalling appropriate boatloads, kernel, modem.
I'm at Bell now. Gonna ask why the hell I've talked to 3 CRTs on the phone and in another store and Knox WASNT EVEN MENTIONED!

If your warrenty is void (knox tripped), you could risk it and try to add all bands to your phone. Maybe it could reset something?

I got the phone replaced through my smartphone insurance package. Luckily I don't have to pay the normal 150 deductible because my S5 was an insurance replacement and within its warranty. As far as the 0x1 causing warranty to be void, I highly doubt that crap will stand up in court. Because you install a custom recovery to BACKUP your phone for recovery, your warranty is void? That's a loud of sh*t! I think that all of us Samsung customers should put together a petition letter expressing our displeasure with Knox. I mean, it doesn't really do anything for us unless you're with a corporation or you pay for one of the upgraded copies. I can't even figure out how to login to Knox on my insurance replacement but it's there and running.... well it was. lol
I'd really like to find out what happened to this phone before I send it back. I think I might try adding the bands.
Anyone else have any ideas as how to reset the Qualcomms through the service menu. I suspect that this is totally separate from Android and that in here is where I messed something up that tripped up the modem settings so it won't read SIM cards. I want to reset the Qualcomm back to factory defaults.

I9505 looses network coverage, how to restore it without restart; HW or SW problem?

Hi, guys. I have a 1 year old I9505. It started loosing network coverage without any reason. It was originally with Touchwiz 5.0.1 when the problem started. I installed Cyanogenmod 13 (Android 6.0.1) to try if the problem is in the OS, everything working, but the problem continues.
I leave it on the table working (with coverage) and some time after that I turn the screen on and I see an "x" over the mobile network indicator and there is no network. Only restart solves the problem, but not every time. Sometimes i keep on restarting the phone in order to get network coverage. I miss phone calls.
I told myself, when restart solves the problem, maybe I can restart the mobile/radio service without restarting the phone. I installed some apps from the play store, which reset the network coverage. No success. When I have coverage, they do reset it and reconnect. But when the coverage is lost (with an ''x''), those apps do nothing!
How can I restart the SIM card module/service?
It is a hardware problem? But if it is, how does a restart sometimes help?
PS: if i toggle airplane mode (when I have the "x" thing), then i cannot turn the airplane mode back off!

Could be your SIM is acting up.

i9505xxuhob7

Tried stock rom from sam mobile.

I was with stock when the problem started.
I suspect the sim card reader.

Bro I mean flash again stock via odin if you know.5th month ago same issue with me.solved after latest firmware fro sam.good luck

i9505xxuhob7 is from a dutch firmware, flash your own country's firmware, the latest if possible. 9 out of 10 this problem will be solved by flashing original firmware as mentioned by other users before me.

OK, I'll try, but it worked 1 year with this firmware. Without any update, it started to make the problem. That's why I don't suspect the firmware it was with during this year.

Maybe your provider did change something on the network or something happend with your efs directory.

Thanks, man.
Phone has IMEI. I suppose no efs problem.
I changed the SIM card with new original micro-SIM. I've installed the newest modem I've found (again). Still no difference.
There is a difference in the behavior when there is no SIM at all and when there is SIM inserted, but no network.
When it looses network coverage:

With normal network coverage:
Lost coverage - SIM card status is "ОК", everything else - not available:
When I take out the SIM card - SIM not detected:
I see that when it looses network coverage, SIM card number is not seen in the app. So maybe it cannot read the SIM card. But SIM status is OK - maybe this is a flag when just SIM is inserted.

You have tried other modem now, did you flash also and try original firmware from your provider so not from xda? If not try that, if not ok try using other sim from friend or someone else other then yours, if that is working then you know something is wrong with your sim, if not i am out of option and it could be your sim reader.
good luck.

Nothing. New SIM, original firm, I even tried this:
http://forum.xda-developers.com/galaxy-s4-att/general/how-to-fix-galaxy-s4-sim-card-removed-t3113480
still doesn't work. Powers up with network, wants my PIN code and a few minutes after that - gone.

Can't restore Baseband, Software version, IMEI and so on

Not really sure when it happened (probably while I was playing around with different custom roms) but my phone managed to lose all private data as well as the ability to "see" what's installed on it.
I can't see my Baseband, Hardware or Software version, IMEI and even MSL is not working.
I can't perform ##RTN# or ##SCRTN# and if I switch to dm+adb+modem DFS doesn't want to connect to it (it doesn't see it on its port).
Also, phone is not recognized by the computer when it's booted but it is in the TWRP recovery.
If I try to ODIN a Lollipop STOCK rom it won't boot, but I can install a Lollipop that's TWRP compatible.
I do have a backup of the efs partition as well as m9kefs1-3 but restoring them didn't change anything.
I've even copied all the partitions from another Sprint S4 (including the system) and replaced them trough the terminal in TWRP but no luck.
I'm out of ideas.
Any help is appreciated.

Install stock tar in Odin. Boot to recovery then wipe internal SD and do a factory reset. That should allow it to boot.

Been there, done that. I can boot stock KitKat nut I can't boot stock Lollipop even with the factory reset. It just goes into a bootloop. Not sure that would change anything.
I can't explain how is it possible to replace the data on every partition from the working phone and still have a "broken" phone.
Is there any other memory on S4 that is not accessible?

From what I can see it seems that modem and system are not communicating - case in point, even if I put my phone in the airplane mode when I look at the battery consumption I can see that "cell standby" percent constantly increases. In the airplane mode this should be off, right?
Also, is there a way to see if the modem is functioning properly or it might be damaged?

I mean if you have service it's working, but other than that the only thing you can do is flash the stock tar. Putting it in airplane mode forces it into Cell Standby btw.

That's the whole point, I don't have service. I'm in Europe now, had my phone internationally unlocked, everything worked fine but now the system doesn't see the SIM card at all. It doesn't even report it as "Wrong SIM card" it just doesn't register it.
I've flashed a stock rom *NAE* and upgraded it (without a problem) trough OTA all the way to GPL1 (NAE-NG2-OD2-OH1-OK3-PI2-PL2) - six updates, problem stays the same. All the time I have the system as "Samsung Official", no suggestions what might be wrong.
And why, oh why, system doesn't want to accept my MSL when I try to do the ##RTN# or ##DATA# edit. I doesn't matter what number I put in, I still can't press OK. And ##MSL# "reacts" but does nothing.

Sounds like it might be a hardware problem then, if the software is completely stock that usually indicates it is hardware. Maybe your SIM reader or the SIM card itself is damaged.

Whatever it is, seems like the modem is dead (or there's no way to communicate with him).
I thought that AT commands might do but I can't reach it from the computer either. Tried DM+MODEM+ADB, RNIDS+DM+MODEM but it doesn't give me any reply. It is recognized in the Device Manager, but when I go to Properties\Diagnostics and then "Query Modem" I get - "The modem failed to respond".
I've tried changing UART between PDA and CDMA (AP/CP) but there's no difference.
I've bought a new phone, can't go around without one, this is kind of a side project now to see what I can learn but it will probably be sold for parts (it's not worth fixing it). Shame.
If you guys have any additional ideas, let me know, now I can experiment all I want.
Cheers!

Mobile data not working with Jio network

Hi Guys,
I am stuck in a strange problem with my Note 4.
My reliance Jio SIM card wont connect to Mobile Data at all. Though it shows volte icon, there is no 4G packet switch indicator next to it. In Settings > About Phone > Status, it shows Mobile Network State = Disconnected.
I have deleted and re-entered the APN settings, restarted the phone several times, erased everything and flashed stock ROM, etc. I have also ticked "Aggressive wifi to mobile data handover" in Developer Settings; have tried it all but nothing works. When I enable mobile data and then when I go into Settings > About Phone > Status to check, it doesn't even show a "Connecting" attempt. It just remains "Disconnected" all the time.
Surprisingly, when I insert a different SIM (vodafone for example), it works straight away. However if I try this same Jio network SIM in an iPhone, it shows LTE and connects to mobile data instantly. So I know for sure that there's nothing wrong with the SIM nor with the phone. I thought it could be due to modem so I reflashed the whole stock ROM but it still wont work.
Please advise what are my options.

Bump! Anyone please?

I suggest you download and flash stock firmware from link below.
You must have "INU" indian CSC for IMS settings to get volte work.
https://www.sammobile.com/firmwares/galaxy-note4/SM-N910G/INU/download/N910GDTS1DQG2/180867/
Flash firmware then go to recovery and wipe cache/data factory reset/reboot.
Complete setup/set your apn settings correctly.
Try and let me know if it works.

I can see your Volte/LTE is already active in screenshot.
Definitely your apn settings is not correct.
Nothing wrong with firmware/modem/csc/bootloader.

I suggest you download and flash stock firmware from link below.
You must have "INU" indian CSC for IMS settings to get volte work.

Flash firmware then go to recovery and wipe cache/data factory reset/reboot.
Complete setup/set your apn settings correctly.
Try and let me know if it works.

I've installed the apn settings i received via sms as well as manually entered the apn too. I even called the network provider to verify the settings. The apn is jionet. Not sure what else can i try.

OK I tried 3 different JIO network SIM cards in this phone. Nothing works. Whereas all these 3 SIMs work on a different android phone. The settings are exactly the same as the other android phone. However its worth mentioning that the moment I change the MNC code inside APN Settings, it made the whole APN disappear but I got LTE icon. Nonetheless its of no use because by doing this , the voLTE icon disappeared. And even with the LTE data connection, it could not load any website. When I reset the APN back to defaults, the volte icon appeared but LTE icon disappeared.
Not sure what else is left to try.

Just got the SIM replaced. Same issue
I refuse to give up knowing that it has worked in the past and the fact that other network 4G SIM cards work fine, i dont believe this is a phone fault.

There's an interesting event that i would like to share with you guys.
If I leave the phone idle for around 2-3 days, the phone brings up LTE icon and connects to mobile data. Yes, this only happens when the phone is idle for 48 hours or more. However the moment i toggle airplane mode or if I restart the phone, mobile data disconnects and wont connect until next 2-3 days. So it works this way and only with this 1 particular network operator. With others, it works instantly.
Is it a faulty motherboard (modem)?

I am facing this same issue with my Galaxy Note 4
