[Q] No Signal At Boot With New ROM - General Questions and Answers

Hi there, just wondering if anyone can help with a small problem I'm having after flashing a new ROM - {ROM}[T][STOCK][JB 4.3][UB&LB][9.2.A.0.295] Official Firmware - Rooted&Deodexed 18/02, by DaRk-L0rD. My problem is that when I first turn on my XperiaT, I usually have no service on my phone - i.e- I cant make calls at all. The phone works fine for everything else, but I have to manually go into Settings-More-Mobile Networks and after a few seconds the phone picks up the signal and the bars appear. If I don't do this it will just sit there for hours not getting anything! I've tried entering the Phone Information menu through *#*#4636#*#*, and setting the preferred method to WCDMA, and I've made sure that in the Mobile Networks settings that is also the preferred method, however it seems that if I reboot the phone, or the battery dies and I switch it on, it randomly forgets these settings and I get nothing. If I try to enter the Settings-About Phone-Status screen when I've no signal then I get force closed, but when I have signal it opens no problem and my IMEI is there and is correct. Also, sometimes the little red missing SIM icon appears alongside the red x on the bars, although this doesn't happen all the time.
It's a small issue because it only happens maybe 80% of the time, and it's not a big deal going into settings and reactivating things, but it's a bit of a hassle at this stage.
Previously I used "[ROM]XperimenT 3.5[T/TL][9.1.A.1.145][Locked & Unlocked][23/09/13]" by TiMiN8R without this issue so I know that the phone/sim are actually ok as it only started immediately after flashing the new ROM.
You can see from my three screenshots that I have no service for two minutes, enter the mobile networks menu, and finally after being in that menu for a few seconds up pop the bars!
If anyone can help me out I would really appreciate it.

Sudden Disconnection from network?

So out of nowhere, my HTC Sensation no longer connects to the network. I would get roughly around 5 mbps around my house, but just all of a sudden, it stopped working. I tried rebooting the phone, and turning on/off airplane mode, and it just doesn't seem to be working. Anyone have any more tips before I try and factory resetting? Also i think I may be experiencing a bug because every time I open any app, I get a very quick glimpse of the weather instead, and then the app opens up. Thanks
What was your previous phone with t-mobile? If you don't have an "android plan" it seems that T-mobile is blocking you from data.
Check this thread: http://forum.xda-developers.com/showthread.php?t=1128335&highlight=data&page=5
I had the same problem two days ago and had to do a factory reset to solve the problem.
Previous phone was MyTouch 3g, so I'm sure I'm on an android plan
Thanks for the link, I'll check it out
Don't assume it's your phone. It's possible that service in your area is down. If you have another t-mobile phone check to see if it has reception. Next go into settings, wireless&networks, and select mobile networks. Then choose network operators and select automatically. If nothing comes up I would call t-mobile because resetting your phone.

AOKP JB 4.1.2 Mobile data dropping and not reconnecting

I’m currently using AOKP Jellybean 4.1.2, the supposedly stable, reliable milestone version found here: http://forum.xda-developers.com/showthread.php?t=1804223
I'll try to be as thorough as possible in hopes that someone will respond and know what to do. I apologize in advance for being long-winded.
I didn’t have any issues last night when I first flashed the rom. I was able to watch youtube videos using the mobile data. I was also able to turn on wifi to sync some files from my dropbox to my phone, and then turn off the wifi with no issues. However, today after connecting to a wifi network to download a few things and browse the web, I disconnected from the wireless network and the mobile data curiously did not start up again. I DO have cellular service (3-4 bars), and I can make phone calls and check my voicemail by pressing and holding 1 on the keypad, but my mobile data doesn’t work. I looked around for some solutions, and I've since restarted my device several times, tried toggling airplane mode on and off, and did several combinations of reboots with airplane on/off and no dice.
Everytime I use the toggle in the notificaton bar area to turn off wifi, my internet connection goes with it. It says “no internet connection” in the notification background at the bottom of the screen. Once I turn wifi on, I get my internet back and it says “at&t” at the bottom, but I don’t actually get mobile data because apps like “At&t Visual Voicemail” which require mobile data to function don’t work.
I tried flashing the 1.85 radio to see if it would connect to mobile data, and same issue persisted after reboot and dalvik/cache clean. After that failed, I flashed the 2.20 radio + RIL zip files seperately (which is what I understand came with the rom), and still no dice.
For reference, my HTC One X was rooted with 1.73 firmware (I never tried to update it until last night). I did the CID spoof method to unlock my bootloader, and installed the newest version of TWRP on it. I flashed the rom and the gapps package. I used TiBu to restore program settings and a handful of my out of market apps, and the rest of my purchased apps downloaded automatically from the market after connecting with my google account. I had literally just finished reinstalling the last of my apps today via wifi when this issue started to happen.
I'd really prefer a practical method of getting this fixed that doesn't involve starting over with a fresh rom install. Reflashing at this point would be something of a nuisance since I don’t have much free time to begin with. And hey, it took a long time to load up all of my apps just right
However, if there is no other fix that anyone is aware of, I guess I could reflash or in the worst case try a different rom. It’s a shame because the rom otherwise is really smooth and runs great on the phone, in addition to not using a whole lot of resources and having a decent battery life.
Thanks in advance for any suggestions and solutions.
Here is an image of my battery drain screen showing what my mobile data is supposedly doing despite not being able to get a true data connection. Even with my wifi off, there is supposedly medium mobile signal.
And attached is another image of what happens when I turn my wifi off. I pulled the notification pane down and you can see that it says "no internet connection" at the bottom. Also, you can't really see it in that cap, but the mobile data bars behind the notification area are colored white, and there isn't any "H+", "4G", or "LTE" notifiers visible.
Edit: Attached a third image showing the "white" signal bars (i.e. no data connection). Yes, my mobile data is turned on, and I'm obviously not in airplane mode.
I figured it out eventually for anyone interested... Apparently the APN were not set. They existed on the APN list but were not visible due to a glitch in the ROM I guess. I had to add a custom APN and then the other ones suddenly appeared.
Thanks anyway.

[Q] Wifi and post-call issue

Hi
I bought this phone 3 months ago and have been going through 2 major issues which have become a pain in the **s.
1) Most of the times, while making a call the screen freezes and the timer is stuck on 00:00, and the UI stops responding to any inputs, which means i cannot use In-Call features. If there's a need to make another call after the previous one then the phone needs to be locked and unlocked since the UI doesn't respond to anything without lock/unlock trick.
2) This one is more annoying and it's about Wi-Fi.
When I connect my phone to the wifi and leave it idle for say 5-10 minutes (provided there's no data being exchanged between the phone and router) and then try to open a website, it just doesn't open it with any browser and all other applications which require internet access stop working.
I have tried changing routers and even tried keeping my phone next to the router but the problem still remains. STAMINA mode is always disabled and "Keep wifi on during sleep" is set to "Always" and "WiFi optimisation" option is also unchecked. To make it more clear, the wifi icon is still displayed after idle time of 5-10 minutes on the top right corner with the uplink arrow lighted up and the downlink arrow not lighting at all.
Please reply if somebody else has the same problem and has any solution to it.
I am on stock ROM, with the latest official update 15.3.A.1.14, everything as it is.
Faced same issues for a while, after unlocking bootloader, rooting and installing a generic firmware(europe CE), issues are gone. Original firmware was with Vodafone branding and a lot of crapware.

[Q] Constantly loosing connection

Almost since I got my nexus 5 last year it has been loosing its connection about two times per day. It does this in three different ways.
1. total loss. The little outline of a triangle appears and a notification that I have lost my connection. Clicking the notification opens the manual selection of networks. I select the network and all is fine.
2. full connection with an exclamation mark. solves it self by waiting for a while.
3. full connection with H/3G but when trying to access the internet there is no connection. This one is really weird. The solution here is top open the quick settings, select flight mode, which greys out the connectivity triangle but keeps the H or 3G part white on top of the greyed out triangle that has a slash over it. About a minute later the H or 3G disappears and I can turn off aeroplane mode. This either restores the connection or jumps to problem one.
First I thought its a hardware problem, but since I don't want to part with my phone I never sent it back to google for fixing.
When android 5.1 was released I installed that manually and surprisingly did not have any problems at all after this. But then I went abroad and using the same sim connected to a local network in the country I went to. It took 4 tries to join one of those networks. When I then came home this problem started again.
My thought is that there is some setting that should be there that stayed from my trip. I have tried clearing all caches from the storage in settings and the dalvik cache. No difference. I'm not to keen on re-installing my phone again. So my question is, has this happened to anyone else? Did you solve it? Is there something I can do to remove all previous settings for the network to make it work again? Other suggestions?
This happens to me, at least 4 times a day for me, it has only been doing it since I installed 5.1 on my nexus 5, which was a brand new one from Google since I smashed my screen and they just gave me a new one, I'm in the UK btw, not sure where you are but it does take forever to connect to mobile network when I turn wifi off too.
I constantly lose connection at my house going from E to H+ to LTE throughout the day

Click to expand...
Click to collapse
I'm in Spain.
For me it happened before 5.1 as well. But 5.1 fixed it temporarily, until I travelled with my phone. Have you had to switch to another network with that phone?
For some reason when manually looking for a network it seems to be running on a timeout function because it takes me 60 seconds to get the list, always. This feels like a very antique solution, they should just populate the list as a network is found like wifi does it.

Phone only working with 2g enabled

Hi, everyone!
So, my Nexus 5 only works when I set it to use 2g network.
Explaining it more clearly: when I set 3g, everything starts to go a little crazy. The phone signal gets lost back working, sometimes it doesn't even recognize the sim card
When I try to access network settings and network operators it gets really slow and sometimes the phone crashes and reinitiates.
I've tried setting a new rom and I am running the most recent version of Cataclysm right now. I've tried changing the phone modem driver too (actually I think I have just reinstalled it) and nothing.
Interesting thing is: sometimes when I turn 4g on, the internet signal works, but when I try to make a call, the signal gets lost and it appears a "turn off airplane mode" pop up.
That's it, guys. Thanks in advance for any help you can give to me and I'm sorry for any english mistakes...not my native tongue.
