[Q] After 4.4/NAE update, only EDGE is working... 3G crashes on GSM

Background:
- Sprint L720
- International unlocked with GSM SIM
After updating to a new 4.4 ROM (Slimkat) and NAE (modem only from the modem thread), connecting to anything other than EDGE causes, what seems to be, a modem crash. If I force "GSM only"/2G connection, it's stable with EDGE. If I try to connect to 3G, I see "3G" quickly flash on the status bar next to the signal indicator (I have full service), and then the whole mobile connecting drops and resets... then it goes back to having full service, but no data connection at all - until I got to mobile settings and set it back to "2G" and it goes back to stable EDGE.
I am overseas with the phone (it's fully unlocked and I got a strong H+ connection with the old CM ROMs at the same location), so I am wondering if it's an issue with the new 4.4 ROMs not supporting GSM? Perhaps some sort of baseband/modem mismatch? I also flashed NAE (modem only) as well when I did the ROM - I have since downgraded, but perhaps it isn't fully downgrading?
I applied the MF9 full one-click, no joy ... I did a factory wipe and applied the 4.2 factory image from SamMobile, no joy...
Looking at the logcat, I see something along the lines of an error for 'Mobile network type unknown: 0'...
Any help would be greatly appreciated - only having EDGE is driving me nuts, especially when my actual mobile network here is very fast..
Let me know of any information I need to provide - Thanks

Ok, update - I applied the MK2 modem and then NAE, as I saw someone else do because they said that the NAE file is missing some things... no joy
This all seems to have happened after applying the NAE modem-only file - Does SlimKat not support GSM? I don't think it's SlimKat, because, even going back to the fresh "Factory default" flash that I got some SamMobile, I still had the same issue..
Which leads me to what I think the problem is - the Qualcomm settings. Those seem to be persistent across all ROM restores, so how do I go about resetting the QUALCOMM settings to default? Is there something I can do with EFS Professional/CDMA Toolbox or something?

[Q] G900F won't make or receive calls

Hi
I have searched the forum beforehand and can't find a post with the same symptoms so...
I have just bought an S5 which will not make or receive calls or texts, although my mobile data works fine!
The guy I bought it from said he had it brand new and sealed, and used a Giff Gaff card for a few hours with no problems before the issue developed. I'm using Virgin. It was apparently from new, a Three network phone but did not appear to be locked to their network.... no unlock messages appeared when my SIM was inserted, it all appeared to work until I tried dialling!
I get a good signal and all the indicators are that the system is connected and functional, but when I dial any number the phone dials briefly then shows "Call ended". Texts just fail after a short while. Emergency calls work OK so the radio seems fine.
From the wonderful Phone Info app the following are installed:
Bootloader version: G900FXXU1BNL9
Baseband version: G900FXXU1BNL9
PDA version G900FXXU1BNL9
CSC version G900FH3G1BNL1
Product code: SM-G900FZBAH3G
I have tried the BOB7 BTU firmware via Odin and this worked ok but didn't fix the problem.
I also tried to downgrade to 4.4.2 with both the Three firmware and the ANG2 BTU firmware. Both just cause the phone to hang at the splash screen.
The serial number, IMEI number and the "refurbishment" check all show the phone as genuine.
Knox is still sitting nicely at 0x0.
Looking through the service menu settings nothing obviously jumps out as a problem but it does seem to be some sort of SIM lock.
Phone info shows the manufacturing date as 2015.01.03 so should be in warranty so I'm holding off rooting it as long as possible
I have scoured the internet and found a couple of others with the same problem but no helpful replies to their queries.
Any ideas anyone? Thanks guys

Try a Giff Gaff SIM in it, if that works, you have your answer

If you have upgraded from 4.4 to 5.09 through Odin as I did with mine which is Generic BTU the phone calls and texts would not work after the update so I did a factory reset then flashed the BTU firmware again did another factory reset and the phone has been fine ever since.
One of my friends got an S5 just before Christmas on 3 Network he was told by them that they no longer sim lock their phones how true this is I don't know but he tells me that's what the sales person told him, but he now has Generic BTU firmware on it not the original 3 firmware, he had to do a factory reset twice before his worked properly
So it may be worth trying bt flashing the BTU firmware again (BOB7) then doing a factory rest, flash the firmware again after that and factory reset once more then see if it works properly

Thanks for the quick replies.
I have flashed the BOB7 and BNL9 firmware several times with factory resets... no difference. I have also tried to downgrade from the original 5.0 to 4.4.2 (UK S5 didn't get 4.4.4 as far as I'm aware) but the phone hangs on the splash screen and I then can't boot into recovery.
I am waiting for a Giff Gaff SIM to try but tried my mate's contract Three SIM yesterday and again data was usable but no phone or texting. In fact it was worse than the Virgin SIM as it displayed no network whereas the all the Virgin info was there as it would be on a working phone.
I originally thought it was a faulty radio but as emergency calls work I have ruled this out.
One thing I've noticed is that in the Service menus there is sometimes the message to "Pease reboot" - an obvious typo but not something I would have thought Samsung would have overlooked. Maybe it's a dodgy clone. Anyway of knowing for sure?
One other thing that may or may not be relevant. In my working phones with the Virgin SIM, the Service menu shows the "Speech Ver" as "FR FR FR" as does the dodgy S5 when it has the Three SIM in it. When I put the Virgin SIM in the phone the "Speech Ver" changes to "AMR, EFR, FR". The "FR" I believe means "Full Range" so is that a contributing factor?
I've attached a screenshot of the phone menu with the Three SIM inserted.
Thanks for your help so far guys, it's much appreciated, this has me stumped.

Thanks for that mate, mine compares ok with yours, particularly the "About" status.
I have now tried 02, Three and Giff Gaff sims as well as my Virgin sim. Same problem, can use mobile data but no calls or texts.
reflashed 3 more times with a factory reset after each, same problem.

[Q] Issues with Data Connectivity

Hi,
I bought a Unlocked (supposedly) N9005ZWEBTU (UK) off ebay (bad move I know), they shipped out a N9005ZSUGOC3 (HK) variant. I'm currently disputing this over ebay but would be happy if i could fix this through software means.
I'm in Australia on the Internode (Optus) network and my Mothers sim is on the Vodafone Network.
The phone is a gift for my mother, she updated it to the latest 5.x build over wifi.
Getting to the problem, the phone shows data connectivity (H / 3 in statusbar) but will not receive / transmit data / calls / sms over the network. When turned to 2g only it will get data and function normally.
I have tried Region Lock Away multiple times with no change in behavior. Wiped the phone numerous by trying factory resets / recovery.
The phone does not ask for an unlock code at any stage.
Getting to my question, would flashing a different ROM / Modem fix these issues I'm seeing or should I go through the hassle of returning the phone to the seller?
Would downgrading the phone back to a 4.x.x build then using Region Lock Away help?
Thanks for any advice
EDIT: Yes this is a legit n9005, S-Pen is working (tested multiple pens), batteries are interchangeable between my n9005 and this one.
EDIT 2: Done some more digging, ill be checking out the IMEI for the "super IMEI" when I get home.

Install this APP too and add some screenshots. You will lose the warranty if you downgrade it. You will lose the way for return it too.

No service, emergency calls only after upgrading to android 6.0.1 by OTA

Hi! I have an A5 (SM-A500FU) bought in Italy last year, Im using it since then in Argentina. With android lollipop I have never had issues with lost signal, no service messages or network not available. But since upgrading by OTA to Marshmallow these problems started. I have looked everywhere but I cant find anything that helps me. Also my service problems are not always present, sometimes I do have signal, but mostly when im out in the street. At home, for example I have no service and "only emergency calls" message. I'm using right now and old Moto XT316 with the same SIM card ( Claro AR) im using in the A5, and it is working fine, recieving network signal ( it is also a new sim card, just in case old SIM was the problem). The thing is I can´t use my A5 because it is constantly losing signal.
Thing I have already tried and didn't work:
- Changing to aireplan mode for a few minutes
-take out SIM card, restart the phone, turn off phone, put sim back in again, turn on phone
-verifiyng the APN for my network Claro Ar was correct, manually searching networks ( At home for example, it only finds Personal and Movistar (sometimes) but never finds Claro ar)
-Doing factory reset
-Reinstalling official firmware (PDA version : A500FUXXS1CPH2; CSC version : A500FUVFR1CPG2) with kies3 ( smart switch gave me an error)
-Flashing the UK BTU ROM ( the old one was from Vodafone Italy, now Phone info app says my mobile operator is 72234, while befor was 722310 which is correspondig with claro ar, what does this mean)
what could be causing this problem???? Im really starting to desperate now...
I read something interesting online, searching for some answers I got to the experience of some guy who had a very similar problem. Short story, his had to change his phone's network configuration in the "radioinfo" menu (or whatever the name of that hidden menu is) with an app named Network and force his cellphone to use only 3g or 2g. Turns out that his phone was trying to use LTE but LTE was not available in his region. This solved his problem. Mi phone can't use LTE here in Argentina because it is Italian, and since I have it it never conected to LTE network (I guess we use different frequencies) So I was thinking maybe my phone is also trying to use LTE but since it won't reach 4g signal ends up with no signal at all, excatly like this guy's phone.
But, apparently I need root access to get to this menu or even use this apps, is that correct?
So, should I root my phone to try that? does that story make any sense to you? Any advice?
Downgrade to lollipop I read is not my best option, also rooting it isn´t , but I'm starting to run out of solutions.
I add this information that could be helpfull:
Product Code : SM-A500FZKUBTU
Original CSC code : BTU
Active CSC code : BTU
PDA version : A500FUXXU1CPH3
CSC version : A500FUBTU1CPH1
Baseband version :A500FUXXU1CPH3
Android version : 6.0.1
Build number: MMB29.A500FUXXU1CPH3
Mobile operator :72234
Also IMEI number seems to be fine, it starts with 35 and matches the one in the back of the phone.
Sorry It is such a long thread!! Thank you very much!!

S7 Edge (SM-G935F Exynos) Carrier Flash ROM Question

Hey guys, i was wondering if i can flash firmware from other carrier without bricking?
I bought my phone last year locked to carrier, and I unlocked it using doctorSIM service. Phone itself works fine, and as I'm not living in country that i bought my phone from originally, phone gives a message "No SIM card installed" sometimes once a week, sometimes several times a day and i need to remove SIM card or to restart phone to make SIM card work again.
Please note:
- SIM Card from my original carrier (from one that I bought my phone from) works PERFECTLY fine
- My other SIM card (that my phone constantly rejects) works in other phones just fine
- I have tried to reset the phone, and carrier bloatware constantly keeps installing
- EDIT: Wi-Fi and 4G are working PERFECTLY fine
What to do? Any ideas?
Thanks in advance and sorry for gramar mistakes

Bump, flashed other carrier firmware, still same problem.

R u rooted? Have you considered flashing a CSC packet for your location?
I have a 930S, and works fine with the Korean ROM/Chinese language here in the US, on ATT service.
I have flashed the ATT, XAA and TMB CSC sets, and though the phone worked, and loaded the correct USA carrier info, I lost the phone code ability, which I could not solve.
In the end I went back to the original Korean ROM and it's CSC packet. Interestingly, though it works perfectly here in the U.S., and I can use/input phone codes, it still shows Chinese cities for my 'Region", none of which I have selected. When I do a search for local towers, it locates and correctly identifies AT&T, T-Mobile, etc. I select ATT. The Chinese cities remain in the region selection, none selected.
Wait and see if someone knows if CSC (Exynos or US based CPU) are interchangeable. I used CSC packets from a universal ROM setup (non-USA).

I'm not rooted, as I use Samsung Pay and have more than one year of warranty left. I will try flashing CSC of the current country I'm in (Austria). Thanks for taking time and writing all this, this problem is unbearable

Hello!
My s7 edge is in trouble, it freezes sometimes, and sometimes it gets a full screen of pixel color flaws, with that problem my root smartphone works two weeks. Sometimes this error occurs in the ROM installation process, I insist on the installation until I can. I tried to install superman rom and due to this problem, the smartphone in the screen of death "exception of bootloader" (But it's already been resolved)...
When searching the internet, I saw that this could have a problem in flash memory.
After all history, I ask;
I could use a twrp file system repair function to try to solve this problem? And how to proceed?
(sorry for the use of google translate)

I am, by far, not educated up on TWRP, so I'm not sure what you mean by "repair", other than making sure your data partition is formatted so it does not cause the issues you are talking about.
Here is an interesting read:

Hey guys, update on the problem, i replaced sim card and it works just fine, i will post updates as time goes on
Thanks for the help!
