No 3g after flashing 4.2.2 and 4.1.2 firmware.

I own a ZL C6502 with 4.1.2 firmware and root access.
I decided to try out the new 4.2.2 firmware (Xperia ZL_10.3.A.0.423_Indonezia С6502.ftf ) After flashing it i noticed that the 3g isn't working. I flashed back to 4.1.2 firmware (Xperia ZL C6502_10.1.A.1.434_global) but the 3g issue is still present. I can make calls no problem but no internet through the data connection.
Every time i flashed a new firmware after first reboot i get this message : "Factory startup service please wait for power off button"
Some help would be appreciated.

The "Factory startup service please wait for power off button" only happens at the first boot right after a flash which is normal. I hate to ask dumb questions but obviously your APN settings were wiped after the flash, have you reconfigured your APN settings to make data work with your provider?

Haven't reconfigured the APN as i have no clue how to do it. I will search on google but if you have any suggestions on how to do it please do so. Thanks.

Google your 'carrier' apn, or easiest way is bring it to the 'carrier' store they will set it up for you.
APN setting is in settings/More.../Mobile networks/Access Point Names - hit menu (the three dots) choose 'New APN'. Enter the result search from google.

Try this easy solution. Turn on your phone, remove the sim card and then put it back and turn on your phone. Maybe the configuration will pop up by itself as it should.
When i had my similar problem i went and manually configured the settings. But it also worked out by itself when i removed the sim card afterwards.
Good luck!

Note 2 No data coverage after 4.3 update?

Just upgraded to 4.3 today but my data services don't seem to function well. Can someone please help me?

Same problem here..

Looks to be an issue with TWRP, have either of you tried the latest CWM recovery? I was hoping to avoid it since my nandroid backup was TWRP (I'm honestly not sure if there's a difference) but a few posts in the main threads are reporting a similar thing.
EDIT: Nope, same issue, at least for omnirom.
I take that back, it does work.

Go to Settings - Network Connections - More Networks - Mobile Networks - Access Points Names
Check and see if you have the APNs from your provider, they usually are 3 ([Provider] Internet, [Provider] WAP, [Provider] MMS - in my case). Make sure [Provider] Internet is selected. When I usually re-install some ROMs, the WAP APN is selected by default and that will show me the 3G data icon but it will not let me access internet resources with my data services.
If by any chance you are missing the Internet APN, search a bit on the internet for your provider APN settings for internet access.
Hope this works.

It just acts like there's no SIM card at all. I don't understand it completely, but CWM is doing something that TWRP is not (or vice versa) and is causing this issue. Took my 7105T from virgin vanilla stock to the omnirom 4.4.2 nightlies yesterday and when I flashed from CWM the issue was resolved.
That said though, I'm unsure how this will affect omnirom's updates so I might need to switch to cyanogenmod. Shame, because I do prefer TWRP.

I don't know what you guys are talking about but I can't even access the APN settings, its invisible. I have a SCH R950 note 2. H2o wireless already took my money but told me I needed to unlock it, even though I can't unlock a CDMA phone. im so confused because it is quad band and has sim card slot but no one can unlock it and I cant find how to flash to h20

Can't make calls out (Random only on network mode WCDMA/GSM (Auto Connect)

Hi.
I have a Samsung Galaxy S3 T999 model on carrier T-mobile. Lately the phone has gone nuts and will get stuck on dialing out and will never make the call. Everything else works fine. Sometimes I have to soft reset, pull the battery and that will fix it for a call or two, then it will get stuck again. I have contacted T-mobile about this over 5 times and none of them can help. We tried to change the sim, reset the account. Etc and nothing. I have reset the cache, factory reset and even put in a good working sim card from another phone and the same problem comes up. During my latest troubleshooting I have narrowed it down to where I switch "network mode" to GSM only and that can make calls out all the time, but the data stays on E (which then I can't use the internet because it's so slow) When I switch back to auto I am sometimes able to place calls again, but only a few. After I test a few calls and leave the phone for a few minutes the phone will get stuck back on not making calls out and just saying "dialing".
Has anyone had the same problems or know of a fix? Currently I have been trying to flash the modem to different versions to see if that fixes the problem. The first two modems I have flashed did not work and came up with "unknown baseband".
If anyone can help I greatly appreciate it.

This is a known issue with 4.3.. What firmware are you on? Assuming you flashed the correct baseband for your device, the 'unknown baseband' message sounds like you are in 4.3 but what build? You can't flash any modems successfully less than 4.3

I was previously on 4.1.2 when the problem first started. I updated it to 4.3 and still the same problem.
jss15j.t999uvuenc2 build. (I put this one back on last night so at least I can use the phone today when I am at work)
I was just hoping that the device didn't go bad when it was on 4.1.2 because it was working just fine before the problem started.

Was it official update to NC2 by OTA/Odin or you just flashed a ROM?

NC2 was OTA. After doing some searches it said that OTA could of been corrupt, so I went and downloaded KIES and did a reinstall that way.
When I upgraded to 4.3 I tried that default baseband out and had the same problems. That is when I was searching on google and came across this forum and also the thread about flashing modems.

What APN (Access Point Name) are you on ? Also what is your Preferred Network Type set to ? Its located in Settings > More I think.(I don't use Stock Firmware)

APN is epc.tmobile.com
Network Mode current set to GSM (the only way I can make calls out without the problem occuring)
WCDMA/GSM (Auto Connect) is what it should be on so my data is at 4G, but the calls is the problem here

I am not sure but can you check the settings of the Dialer to see if there is ways to choose Lookup providers ?

Nope don't see anything in the dialer about selecting a provider..

Its supposed to be something about Choose Lookup Providers. At least that's the way it is on AOSP.

I suggest Odin flashing the stock NC2 firmware and then factory resetting from stock recovery. (Backup first of course!) If it is still an issue, it will most likely be a hardware problem. From what you have said so far, I believe that you will find this to be the case. Could've been due to damage from a drop, or even overheating at some point. Or it could just be that its simply due to hardware degradation over time.

[Q] T-325 NK1 firmware Wifi problem

Hi
I installed the new NK1 firmware on my t-325 and since then my inernet connection keeps dropping with "AP currently not in use. Internet connection too slow" message. The internet connection is obviously not slow and signal strength is maxed out. Is there anything I can do ? I have already regretted upgrading. :crying:

I have the sm-t320 also on the NK1 firmware but I haven't experienced any wifi dropouts , but I did a clean install by doing a factory reset, have you tried to remove the AP and re-add it back in?
To remove the network go to Settings - Wi-Fi - Long Press on the AP and press "Forget network" , then refresh networks and re-connect to it, or if SSID is hidden scroll down and click Add Wi-Fi netwrok.

Yes, I tried everything but to no avail. I even selected another channel on the router. My wife has the same tablet with the older firmware and everything is fine by her.

It seems that I need to roll back to the previous firmware but I don't know how to start it since I have never had a Samsung before. I downloaded the original firmware, Odin v3.9 and installed Kies to have the necessary drivers. I don't want to brick my device, so is there anything I need to be aware of before I start flashing ?

No 4G

I've searched and tried the suggestions here and installed creepers (very cool) and still only 3g I'm on the latest Emotionos on my 910v with newest twrp. This is a great rom and I donated anyway but has anyone had any luck getting the 4 g back?

Do a full firmware flash. Use the clp1 without recovery and aboot. That's the god fix. Then flash your rom again. All good.

Thank you thank you! Worked like a charm! I thought I searched everywhere and was freaking that I was gonna have to start from scratch. But this was perfect. I hope someone else finds this and thanks you.

no, its not necessary for this.

Worked for me as well(!)
Flashing LTEfix.zip, then resetting networks to default worked for me as well.
Samsung N910V (trtlevzw) EmotionOS 20170129-OFFICIAL Baseband (modem) N910VVRU2CPF3.
Was only seeing 3G, now see 4G. Not sure if that's a change in indicators or actual 4G (LTE-A), but it seems to have worked.
Thanks!

Hi, I was wondering if you could point me in the direction of the thread where the lte fix came from. I just want to do a little more reading on it. Thanks

There are no words, weard1212! I owe you a beer or pizza! I was gonna have to buy a N4 off swappa since losing 4g a week ago. THANK YOU SO MUCH SIR! The ltefix got my 4g back!!!
I do have a new issue though. I'm on emotionOS build 20170328, baseband cfp3 as well. In global network mode I still only get 3g, but 4g works fine when I switch to wcdma/lte. Even weirder: in the expanded pull down notification bar it says "no service" where it should say "Verizon wireless" under the cellular data quick tile button (4g still works though). Any ideas, I'm almost back to being perfect! Thanks again friend!

okay so I can't send texts over lte/cdma? They work on global/3G but not when I have 4g. I'm certain this can be fixed and that's it not hardware. Please, anybody have experience or opinions? Ran the flash twice now, reset apn, network settings and restored nandroids. On global mode under apns it's blank, "the apns for this user cannot be displayed". Flash a different modem perhaps?
