[Q] No Service Menu and No LTE - Xperia SP Q&A, Help & Troubleshooting

Hi, Guys and Thanks for the help. I've tried searching everywhere on this forum and google, and can only find a few posts about this issue but nothing I have found has been usefull. My device is as follows:
Sony Xperia SP C5306
Cyanogenmod 11
Android 4.4
Kernel 3.4.0-perfg5dce312
Bootloader unlocked
My 4G LTE is not working as I am unable to access the Service menu by typeing *#*#7378423#*#* . When I input this nothing happens. I have tried wiping all user data, factory reset, and reflashing CM11. *#06# works and am given the IMEI. Also I've tried installing other Kernels. As a final last resort I even tried installing some app off the play store, that is supposed to bring you into the service menu.
Note: The first time I installed CM11 I was able to access the Service Menu and turn on LTE, but I needed to wipe all user data, because I removed my sd card that had apps installed, and I believe this messed the phone up.
Thanks for the Help.

Okay I was able to change the Band by typing *#*#4636#*#* Set preferred network type: LTE/GSM auto (PRL)
Sorry for waisting anyones time, as I do believe this is posted somewhere I was and am still unable to find that thread.

Hmm I don't know, we don't have LTE in my country, but maybe you could try checking your APN?

[Q] No service, no APN - CM7

First of all, i want to introduce myself a bit, cause it`s my first post - i followed this great forum for quite a while now and learned a lot by reading stuff, though i`m still just a user... by using some howto`s i was able to flash huexxx rom zeus 3.2n and i`m very satisfied with it in daily use.
However, i would like to use Temaseks Kang or the stock CM7 and that`s my problem... It doesn`t matter which of the two roms i try - i don`t get service and there is no apn. i can`t check for available services but phone connects if i choose to sign automatically, but even then there`s no apn available.
I tried to fix the apn manually but can`t save - means, i can save but apn won`t appear after saving.
Additional information: I did a full wipe before installing cm7/temaseks kang, wiped dalvik cache, tried factory reset after installing - nothing works.
So, i hopefully await some help from this community - hope it`s not too noobish...
greetz, nbt
Happened to me once. All i did was as this :
- In APN settings, press menu and click "Reset to defaults".
- Either default APN settings from your service provider will come automatically or it won't.
- Even if it doesn't appear, reboot your phone. Just give a little time before rebooting the device after you click reset to defaults, so that if sim card is sending any message to retrive the APN settings, it would finish.
I had got my APN settings back after 2 reboots with this steps. Hope you too..
try "Apn Manager" or "apn backup and restore" you can find these in the market, maybecan helpyou
I tried both - no effect
i won`t get a connection to service automatically. If i try to scan for available services, i get an error, if the phone chooses, i get a connection but no apn.
after rebooting, there`s no service-connection and i have to join by hand. argh!!!
anybody a solution for this? am i the only one having this freaking problem?
edit: went back to zeus, got service, got apn without problem... what`s wrong with cm7?

CM 7 rom change and no 3g+mms

Ladies and gents;
So i changed my rom a few days ago for the CM7.2 thanks to a guide on here, and it really impressed me in terms of performance and the whole package.
Problem is, i can't seem to connect to 3g, and cant seem to create any apn's either, device just doesnt do anything when i click on create new apn!
I have made sure that the baseband is on the right selection and so are my network settings...
I have a motorola milestone that used to be locked to TELUS and is now unlocked and using FIDO

Its possible that you might have just had a bad installation. Id recommend you backup your data and apps, go into recovery preform a factory reset, wipe all data and cache, and re-install the CM 7.2 ROM. I have had similar problems to what your having in the past when installing new versions of CM and most of the time re-installing the ROM did the trick.

i tried just doing a dalvik reset and all data+cache, it worked for the volume wake and the rest, but still no 3g connection
A simple battery pull may work.

I had the same problem with both 3G and 2G as well. I had to manually add APN in Settings>Wireless and Network>Mobile Network>Access point names
It works fine now, even when switching from 2G to 3G while connection is active. CM7 7.2.2

gettin No signal cuz i screwed up - fixed

So,all was well with my z1 and somehow my subconscious thought that I something should be screwed up.
Well,I was getting really bad signal reception in my area for 3g since i barely got 1 bar(though i got 4 out of 4 bars for 2g)
.
Now,I typed in *#*#4636#*#* in the dialer >> Phone Info >> Menu key thingy>> Select radio band(well obviously,i thought that if i could unlock more bands,then i could connect to one with more...power) >> Only one option was avaliable--> "USA BAND"....So much for unlocking new bands.well i selected the 'usa band' anyway thinking that is was the default option,
BOOM..there goes the signal reception and i couldn't get it back no matter what i tried: I tried factory resetting,I tried manually factory resetting,I wiped Dalvik Cache n Cache. I reflashed the baseband via flashtool.AND STILL NO SIGNAL( I blame sony for including stuff like this in their phones)
I searched a lot for fixing this on the web and i found that many people had the same problem as me but i found no answers as to how to fix this.
SOMEBODY plz help me,ANYBODY plz help me.
UPDATE: ok, after flashing a multitude of different firmwares via flashtool,i somehow finally got my signal back...yah. So if this happens to anyone in the future,...then go crazy with flashtool
A full reflash is the only way I have come across. You can hardly blame Sony, they didn't give you the code (which works on pretty much any phone).
i fixed this problem, reflashing only kernel (stripped file for LB)

I have a sony xperia z1 with CyanogenMod CM11 snapshot.
after reinstalling does my data connection 3G // 4G not I have checked that the APN is correctly plugged on. I've tried pretty much everything. install an earlier version of CyanogenMod. reset all settings. formatting the SD card. the only way I can get the data connection to work is by installing stock sony software on the phone. what can I do to get the data connection to work with CyanogenMod. have also tried to install cm12 but still does not work.

I think it will be good to know the model of your Z1...
If you are on a C6902, there is an additional file to flash for the modem-related stuff.
of course. it is a c6903
we just made a discovery. by flashing an old enough version of CyanogenMod we got it to work. but when we reinstall the latest we will have the same problem back

[Q] No mobile data after installing custom ROM

Hi All - I tried flashing 2 custom ROM's (Monnlight and Mokee), both install just fine but i am unable to get mobile data on either of the ROM's. Everything works fine on Wifi. I can even make calls fine. My IMEI number is correct, hence not sure why i cannot get the mobile datat to work.
Tried manually entering the APN details, still no luck.
Hoping somebody has a fix.
Have you tried this:
dial *#*#4636#*#*
select WCDMA-preferred or CDMA auto-prl

Thanks Gary, I tried your code and selected various options nine work. I can still see the Exclamation mark and no mobile data. However on the diagnostic page it says "Connected" and network type "HSPA". I have tried multiple settings rebooting, still no luck.
The funny thing is if i switch back to my phone OS which MIUI v6 evrything works fine. I even checked the baseband number its teh same in the working ROM and the non working ROM.
I am really confused what's happening.
It seemed like a ROM issue I installed a non Cyanogenmod based ROM and it worked just fine
