Weird Network/Airplane Mode Issue

A couple of times now, when I'm out and about I lose my cellular data connection. It just stops working. In the past on other devices when this has happened a reboot will usually fix it. But on my Atrix 2, when I reboot the phone comes one with Airplane Mode enabled (please note that I did not turn on Airplane mode). If I try to turn Airplane Mode off, it will just sit and say "Enabling wireless connections" but never actually turn them on. I have to actually do a battery pull to fix this problem. The first time it happened I went and got a new SIM card (as mine was pretty old), and it just happened to me again this afternoon. I'm past my 30 day return policy (bought the phone at Best Buy) so I can't return it.
Has anyone else experienced this problem? Anyone have any ideas on what might be causing this?
Just to reiterate, I did not turn on Airplane Mode, the phone powers on with it enabled and then won't actually turn off Airplane Mode when I tell it to.
i have the same problem too. After it happens couple times, i find out it might be the problem from the at&t address book issue which cause the phone cant read the sim for some reason (as it result, airplane mode keep enable). I also believe it is because the phone has been unlocked so the at&t address book crash. Is your phone unlocked?
Well, i am not quite sure it work on ur phone, but here is how i do it usually.
Way 1- plugin another sim card(sometimes i dun even need to do it), load the at&t address book, it will force the phone to load sim card cause of the contact from sim (then it should work right after that or after reboot)
Way 2- pull the battery for 1 day, it will work after that(but this is kinda dumb)
Hope this can help you XD.

My phone is not unlocked. I could see the AT&T Address book thing contributing, I've NEVER had that thing work right, and thus I don't even have it set up on my phone (it's on there in my Accounts, but it's not configured that I know of because i do my contact syncing through Google).
Battery pull definitely solves the problem, at least temporarily. The only other SIM I have is the old one they took out when they replaced the SIM after this happened the first time. I also don't store any contacts on my sim (again use google for that), so I don't know if doing a SIM swap would solve the problem in a more permanent way since I've basically already done that.
I tried battery pull, but it doesn't work sometimes. The reason i run at&t address book because it would force the phone to detect the sim again(cause of the contact). Lucky it doesn't always happen. hoping Motorola can fix this issue on next update.
**I just think about it, it might be some stupid mistake from motorola that overwrite the memory about the phone status section.
have you guys tried factory resetting it?
I tried to reset but it doesn't help at all
Sent from my MB865 using XDA App
how about freezing or removing the apps from att?

Hmm, I did this just yesterday, I'll give it a week or so and see if the issue happens again after setting my contact storage to my Google account.

ok just inform us what happens.
I have and identical problem.
My phone would turn with the Airplane mode ON and I can't deactivate it, or even if it shows I can, it's not in the menu and I won't get any signal.
I can't recall If it happened because of a change but I doubt so.
I tried factory reset / cache / dalvik, also flashing numerous rom from neutrino to cm7 to cm9 and even MIUI (which worked the first time I flashed it for a day and then same error).
And It will also occasionnaly reboot If I try too hard checking for networks and such.
Any help ?

PIN+Swiftkey= locked+Floating Toucher=overiding security=weirdest xperience

hi
yesterday i had faced very weird problem with nexus 5 (rooted with CF-Auto root).. it got locked on me.
What happened was i installed swiftkey on my nexus 5. I had to go out and battery was low so I turned off mobile data and kept it for charging. I dont really lock my nexus when I am at home but whenever I go out I set up PIN for security and its been the same 4 digits number since my first android cell. So this time I went into settings=>Security and set it up. The only change was that instead of usual keyboard, swiftkey opened. So I inserted the number twice.. Nothing weird so far.. right ?...
Well, what happened after that was weird.. I couldnt unlock my nexus. No matter how many time I tried I couldnt unlock it. I can swear that I inserted my usual PIN but it wouldnt unlock. Then I started panicking. After few unsuccessful attempts the usual prompt came so I waited 30 secs and tried again. But no avail. So there was no option but to recover password via gmail, right ? well I wasnt that lucky.. I tried wrong pin for more than 50 times but "forgot password" prompt wouldnt come. (i hadnt taken nandroid backup for last 2 months so i started getting mini heart attacks ) then I tried 40-50 times more.. restarted my cell 3-4 times.. neither would it get locked not it would give me alternate method of unlocking.. thats stupid right ?? :silly:
I couldnt do anything. I checked online and found out that KITKAT DOESNT HAVE ALTERNATIVE OPTION of locking (or unlocking for that matter). Since my mobile data was off (I dont have wifi) I couldnt lock and unlock it using Android Device Manager (ADM) as well. So I was royally screwed ... and only apparent way out would entail data loss :crying:
I could just use camera and nothing else.
So I slept badly thinking that I would factory reset my nexus the next day. And in the morning it suddenly hit me :good:. I had also installed Floating Toucher app yesterday and I could see the floater even on my camera app. So I touched that.. opened quick launch and enabled mobile data. Then went on and locked my nexus using ADM and then I could unlock it with new password. phew...
so it was in all weirdest experience.
Now here are my findings
1) KitKat doesnt have alternative unlocking method
2) Nor does it lock your cell permanently. I mean you could try all permutations and combinations till you unlock it. (my ancient nokia would lock after few wrong tries..) and thats serious flow in system
3) Swiftkey may have screwed me over.
4) Floating Toucher (though proved as my saviour) could bypass system lock and thus one could use (or misuse) it.
Any thoughts on these people ??
Sorry for looooooong post
and sorry for toooooooo long post. I couldnt wrap it up without telling everything.

[Completed] Sprint note 4 rooted, completely screwed

Got my note back in November, rooted through odin in December. Everythings been grand and perfect.
Till I watched a video on youtube 2-3mnths ago about good rooted apps (wanted to get more daring other than xposed) loaded gsm gestures app? I think was the name. Kept it for a week, didnt use it. Uninstalled it, phone rebooted, instead of the normal "app uninstalled"
After that my phones been laggy, freezes, and freezes and turns off. Its factory wiped itself 8 times. I have countless posts on Reddit timelining everything. Long short is, tried liquid smooth to see if that would fix my problem, lost text messaging with that could only text for an hr a day, flashed stock sprint firmware and rerooted afterwards, have been slow to reload apps on phone, incase of factory reset or whatever. my phone is now taking 75+ batter pulls to get into a normal boot, every 15bat pulls it jumps into download mode "could not do normal boot ddi_mms read fail" and now an ssl text ive only seen once today, ill try and write that down if it happens again.
Finally when I get back into my phone, sometimes I have to update prl to get service again, the other day my phone lost signal and all my network settings were unselected, I had to select them all and my phone was fine, then I was on the phone and it cut me out in the middle of a call and said roaming lost or something, and I had to reapply cdma/lte on sprint.
Im beyond frustrated, im getting married in 2 weeks, and going out of country immediately after, so I need a working phone as most my business is conducted through it. I have no upgrade on sprint, and cant afford to throw out 400$ for a "new" note 4
Please please please someone help me.
Thanks for your time.

Hi,
Here's a thread on returning to stock firmware. That should give you a fresh start,

Need serious help please!

Hey!
So I have been using an android phone from 3 years now and I have been stuck in an huge problem! And I need your help in order to solve this problem. Here is the problem so basically I have a Freetel nico (Japanese brand) which is about 3 to 4 years now running on top of stock kitkat rom or in other words the same rom when I unboxed it. After few months my screen cracked on the bottom near the capacitive touch keys. After the crack the home buttom stopped working! I was all okay with that and the next day my notification panel started glitching and stopped showing any notifications which was really annoying. Now I knew that there some serious problem, so I taught of resetting the phone so I went in the setting and tried factory reset. After few minutes it didn't go to system recovery but the phone just restarted itself. I tried it once again and got the same problem, next step I had was to hard reset it by going into the recovery. When I hold the button and let go it didn't take me to the recovery this time also. So in conclusion I came to know that there was no recovery inside the phone (I did erase the phone through recover about 2 times before this incident everything went well during that time). Moving on I rooted the phone and installed SuperSU and other softwares that could install recovery mode to the phone. I got the same result this time also, I also tried installing a different rom through the stock system update app same result.... After a year of all this work I taught it would be best just giving it to the company service center but I came to know that the company had no longer selling this device and there is no service available .
After all of that tries above I still continued to solve this problem I tried ADB resetting it through pc no luck here also! So if you guys could recommend me some apps or softwares I could try in order to reset my phone please do let me know in the comments. Or you could also ask any scripts that you want to know from the phone which could solve the problem I can do that also!
Thank you

Htc U11+ randoms crash

Hi, since 2 months i have been experiencing random crash on my U11+ i tried to reset my phone today and by completing my phone setup i added the option to restore some of my apps, everything was working perfectly until the phone got to homescreen and the app start to downloads, it crashed 3 times in 10 minutes.
Anyone experiencing the same problem?

It started happening to me as well.
However in my case I've managed to (partially/temporary) solve it by going to Boost+ and change from "Optimize" to "Don't optimize" for following apps: Google Play Store, Google Services Framework, Phone, People.
That did it for me for most crashes but Play Store still behaves weird and the only way to prevent Play Store and it's ridiculous crashes is to do in these steps exactly: as soon as you open Play Store > swipe from left > click on Play Protect > and just go back > Play Store won't crash at all.
I haven't tried resetting so I can't tell if that would solve but there are few posts regarding insane crashes related to Play Store and Boost+.
Might be different for you but you might give it a try

No worries mate
Sorry to hear that it gotten worse
Most of my issues were caused by Boost+'s aggressive power saving option(optimization?) and going though every app that I think does not need any power saving options I just set it to "Don't optimize". Strangely enough - this did help but it is far from solution.
Yeah, phone does have some serious issues such as what I've recently discovered on my unit is if you have 2 SIM cards inserted* and someone calls you or you call** someone sometimes(very often) it freezes right away. By that I mean screen stops responding completely, ignoring any touch input or vol up/dn, power button or anything at all you just have to wait until it crashes on it's own and pulls it self back together.
On first try or after 2nd or 3rd call, it doesn't even have to be answered it will freeze and will 100% soft-reboot. Before it crashes during the call you can perfectly communicate with person on the other end without any problem but sadly it is timed as it is going to soft-reboot.
(dual sim phone and has issues with it's very own purpose of having 2 SIM cards)
*Inserted and active: it doesn't matter if you switched one SIM card off or another one it still happens (Dual SIM manager settings) Maybe my phone doesn't like that there is 1 UK and 1 HR (Croatian) sim cards together? Maybe has to be both UK or both HR? Can't verify that, sorry. Never had dual sim phone before.
**It does not matter is it SIM1 or SIM2 as it happens on both.
Not sure if it's just my unit or I am doing something wrong that is causing this, couldn't find anything online with this problem.
I can reproduce that issue at any given time but have no idea how to debug this problem sadly.
However in my case I no longer need the 2nd SIM card (HR) and now have microSD card inserted.
To summarize
Phone itself is great, I really love the camera (and DNG pictures) and video recording (60 fps all the time), battery lasts incredibly long way better than anything I had before!
I've completely purged play store as it has no purpose to me and I can live without that, coming from previous incredibly bad phones I am not worried about that.
But because of this serious Dual SIM problem, sadly, I can not and will not recommend this phone to anyone.
Only way is to have patience if HTC is going to release patch for this, but looking though U11+ posts, this might take a while.
Personally I'm not worried, I've rooted and flashed TWRP/CWM on all previous devices I had and in any time I'll just reflash original boot.img and restore stock recovery.img (which took a lot of time to find online) so OTA can work and update when it arrives.
Hey! you could bring it to warranty, and maybe they will replace your unit with a new one, yes i did say that the software on the u11+ is not perfect :/, its been a long long time since the european u11+ got any update the .401 version im still on december 1 security patch thats way too slow for a high end phone, i just read that the u11 life is getting android 9.0 pie in certain part of europe :'( thats not fair.
Well as for my problem i got it solved by bringing my device to an htc shop they took 3 days to analyse and all, at the end they just gave me a new unit. well not as if the old one could be repared.
I did say that the U11+ is an awesome device, excepts for sme little flaws in the system everything is just perfect. i choose this one because the the bigger battery i less powerful cpu compared to the U12+. well i can't wait to have my hands on Htc's new flagship next year
