Have to toggle data/airplane mode every so often to get data back? - Xperia Z3 Compact Q&A, Help & Troubleshooting

I have a d5803 - relocked bootloader rooted and running a 5.1.1 rom. T-Mobile. Was working totally fine. Decided to try the 6.0 tft beta from the general section. I originally had the .2099 version but the OTA I'm at the latest.
It was great, but then I noticed sometimes my signal strength bar would have an exclamation point and my data wouldn't work. However, it still said LTE. A super quick toggle of airplane mode would revive it, and it would work again. I am a limo driver so I drive around, and it was kinda random. It would be fine in many areas for quite a while, but then would go inactive.
I figured it was a bug in the beta version, so I went back to a 5.1.1 rom. But I then noticed it still happened. I think it only happened once because I ended up trying to clear all data and completely fresh wipe to do the 6.0 version again. It still happens. I believe it tends to happen when I'm moving and it has to switch towers. Also, when I'm on a phone call, it is supposed to go to H/H+, which it does, but there is NO data connection. A phone call anytime will kill the internet.
Any ideas? I really like this 6.0 version but I might have to go back a stock tft file to see if the issue is still there. It all started when I decided to flashtool the 6.0 version.
Thanks

No 3G with CM 5.0.6

Today was the first time I installed a mod onto my device. I updated the radio to TheOfficial_Nexus1_Radio_Update_4.04.00.03_2.zip and flashed CM5.0.6. Everything has been great, EXCEPT my device won't connect to 3G coverage. It clearly displays 3G, but no internet applications will load (ie browser, email, weather). When I force the device to use only 2G / Edge, then it works fine, but obviously speeds are SLOW. WiFi too works flawlessly. Any ideas? I tried going back to TheOfficial_Nexus1_Radio_Update_4.03.00.21_2.zip and this did NOT solve the problem.
Ideas please? My N1 has become a 2G device in a matter of hours, SUCKS!
I should add I'm on T-Mobile and prior to any modifications today I had excellent 3G coverage.
For testing purposes...have you tried to flash 5.0.3 and seeing if your phone still has 3G issues?
I will try this right now. I was told it doesn't matter if I flash the radio before or after install... true?
No difference with 5.0.3. When 3G is displayed no data will transfer. When H is displayed, then I get good data transfer. However, the H is only there maybe 1 time every 5 minutes or so.
Could be an issue with not having rooted the device properly? When I rooted I never got the SU notification like I have seen in some threads showing a picture where you have to click "allow" for the device to allow root. I do have the app superuser permission on the device, but it's empty when I open it.
Thx
Well you can always just go from scratch. Get into bootloader, flash all of the stock PASSIMG images and then start over...
-flash recovery
-go into recovery, perform the traditional wipes
-flash the rom of choice
-reboot and see what happens
Does this happen in all locations or just at home/work/etc?
i've only been working out of home today. tomorrow ill be a better test. i took suggestions from posts i placed in the official cm5.0.6 thread in the rom development forum... and i changed some information in the build.prop. i think it has actually helped my issue... will be reporting back if i'm wrong..

Trouble maintaining 4g connection

I was trying to update my phone to malladus 2.0 from 12b stock rooted. I must have screwed something up along the way because it was soft bricked. Wouldn't boot and when connected to PC it showed as multiple drives with nothing on them. I was able yo restore with .tot method. Ever since then I can't hold a 4g connection. I tried flashing other radios. And now I'm on xdabbebs 24a ROM. Still the same.
Anyone else know of a similar situation or have any ideas? My only idea left is to try restoring to stock again.
Sent from my VS980 4G using XDA Premium 4 mobile app
*update i found info somewhere online saying to do a factory reset after the tot restoral. I did and kept a 4g connection through the entire night. i just upgraded to 11B (tot restoral is only to 10B) and after doing so i started dropping back to 3g again after about 5 mins of sitting idle. i just tried another factory reset to see if it will help. these factory resets are through the stock recovery btw. if this doesnt work i guess I'll start back to square one and look for a non OTA upgrade path.
I'm having the same issue. I have 3g constantly, but my 4g only works for a short period of time. If I turn on airplane mode and turn it off it connects to 4g for a while, then drops back to 3g. I did the exact same thing you did, soft bricked my phone then downloaded the stock TOT and did OTA upgrades to bring me up to the current Kit Kat software. Any more luck with this?
*Update. I tried the reset with; No change
No luck on my end with the same. I've been through a bunch of things, gone from 12b to 24a and back again, run 4.2 and 4.4 ROMs respectively, and nothing has helped it. As soon as I lose 4G through areas, it just will not pick it back up until I toggle Airplane mode. I hate to do a reset, very much so, but I'm getting to the point where it might be my last resort. I go back and forth through 3G and 4G areas every day, and I can't keep toggling a dozen times every day.
The last Carbon nightly was the most "stable" in that at least the 4G to 3G handoff didn't interrupt data. But still...
And that's assuming it comes back as I write this, because my last attempt at going back to 24A and the Carbon beta, and I lost all data connectivity altogether. No network at all...and of course, not enough posts to ask for help in the Dev section. Gotta love it...

Phone reboots when switching from WiFi to 4g

Here's my issue, when I'm at home and am on WiFi then go outside where I'm on 4g my phone reboots when switching from WiFi to 4g. For example, I'm listening to Pandora inside on WiFi then go outside. When the phone gets out of WiFi coverage and in streaming music it freezes and then reboots.
If I manually turn off WiFi its fine and won't reboot. It seems to be rebooting when its connecting/disconnecting on its own.
Also when I'm out and come back to where I have WiFi access it takes quite a while to auto connect.
Suggestions???

I suggest a full return to stock. It is almost certainly because of an app or installed service not playing nice and causing this issue.
Before the return to stock, uninstall the last few apps you had installed most recently and see if it still occurs. You may get it narrowed down to which one is causing the troubles.
Good Luck
I flashed a backup of when I think things were working OK. I'll see how that goes and then do a restore if it doesn't work. Thx
I'm on vacation and don't have my laptop. There's no way to return to stock without my laptop is there??

You can currently ONLY flash the stock SBF if you are on Verizon since you are on 4.4.4. Verizon is the only carrier that we have a leaked 4.4.4 FXZ (SBF) for. (The other carrier's 4.4.4 SBFs will leak soon, but haven't yet...)
If you are on another carrier,don't do it or you will likely brick. So long as you are on Verizon, you can flash the 4.4.4 SBF since it is available. NEVER downgrade. 99% of the time, downgrade = brick! Always flash the same version you are on or higher.
Thanks. I'm on Verizon and will have to do this when I get home. I think I found the app that was causing issues and I've been good since I deleted it...crossing fingers.

GPS + Data issues

Hello all, I have an XT1063 (Global, single sim) running Lollipop (5.0.2). When I first bought it, it came with Kitkat and everything was working perfectly. I was in the insider program so I got to test drive Lollipop earlier than most people, which was nice and didn't really mess anything up the first few builds. The last build, however, changed that. This is the currently available build to everyone, since the beta program is over. Anyway, the problem is that my GPS will not lock on to satellites, making all map/traffic apps completely useless. As if this wasn't enough, the phone often drops my data connection (H+) and when switching from WiFi to celular data, it can take upwards of 5 minutes to get a data signal.
Could this be a problem with the modem fimwares? What are my options? I've thought about going back to stock, even reset everything from the settings menu once (didn't revert to stock kitkat, just factory settings on Lollipop.) If I absolutely have to go back to stock kitkat, how would I do it?
Any and all help would be much appreciated!

Lollipop has a lot of issues... I have ****ty GPS lock too, but maybe that's because of my region.
I can agree with you on the frequent network drops though... Sadly, i have no solution for that, except to re-save the apn until you get the data working.
However, for the WiFi - cellular data switching, switch on "Aggressive Wi-Fi to Cellular Handover" in Developer Options.... It kinda solves my problem. (Still takes a minute for my data to work)

I see... It's sort of a relief knowing that I'm not alone in this. I've got a friend who has the same exact model, firmware, baseband, everything as me, but his phone is working without a problem...
Would you know of any guide i could follow to flash stock 4.4.4?

There are a couple of them in the development section... But I suggest before you downgrade, why not backup your data and factory reset in lollipop itself? See if your problems continue or not... You'll be wiping data anyways when you are downgrading.

I did perform a factory reset earlier today, but the problems persisted, so I've now downgraded to 4.4.4 and will be on the lookout for these issues for a few days before updating again.

That's cool. And you won't find any issues either... KitKat is rock solid stable.
Lollipop buggy. kitkat stable.

Trouble with dropping data signal on Turbo

I'm having major trouble lately with my turbo switching from 4G LTE to 1x, 3G, or even no signal or data signal at all. It seems to happen more when it hits 15% and the battery saver comes on. But when I turn battery saver off or hook it up to a charger it doesn't connect back up or do anything. I'm getting really frustrated by this because I cant seem to get my phone to re connect to 4G no matter what I do. I put it in airplane mode and even restart my phone; it wont work no matter what. I think its mostly because of the update to lollipop and its a glitch. I was wondering if anyone else is having this issue and if there's any way to fix it besides sitting there for a half an hour wiping the cache and not being able to use the phone.
I'm not experiencing that. Did it start right after you updated? Have you done a factory data reset since upgrading to the pop? Onethng you could try is going into setting and switching it from the factory global mode to 3G/4g and see if that helps. I haven't ever needed to with the turbo but others have and successfully avaoided doing an FDR. Lemme know if that works. We'll get this figured out.
Well I came from a rooted 4.4.4 so I had to reset it back to the original in rooted 4.4.4 in order to update. So technicly yes I did do a factory reset since the update. No I haven't had any trouble since the update until recently for some reason. I've got a signal booster at my house and wondering if my phone isn't trying to switch between the booster and the actual tower, causing it to take more power which makes it loose connection because it can't decide which one to connect to. But I have perfect 4G signal with the booster so I don't see why it would want to switch.
I wouldn't imagine that it would be the booster since you're signal is solid there, but it could always be a possibility. Have you tried switching from global mode under network settings to CDMA/LTE? That solved all the network issues I used to have with my old Razr Max HD. Also, have you taken the OTA that was pushed yesterday? Some people were seeing an increase in signal strength.
As a matter of fact, I updated right after I posted that comment. I didn't even know there was a update till I was looking at Google now and saw there was a small update out. I havent had any issues with connection since the update. I'll post back here if I do come into problems. Thanks for the help though.
Any time buddy! I sincerely hope that solved the issue!
Well I was using navigation earlier today and for some reason, not only did I completely loose my 4G data but it said I lost GPS to. My maps app continued to run but it didn't look like I was moving on the screen, even though I was. Guess the glitched didnt get completely fixed.
It's almost like it does it just at night and when I'm using a lot of data over 4G.
