High CPU Load/spontaneous reboots when activating VPN under Lollipop - X 2014 Q&A, Help & Troubleshooting

Before I start, the problem underneath appears on a fresh installed lollipop installation on a XT1092 which is converted to a XT1095.
After setting up my VPN on my Moto (using IPSec Xauth PSK) I see some strange things happening:
- CPU load is going max ("System" process is using all CPU)
- When pressing the ON/OFF button the device is rebooting.
- Wasn't able to check data connection due to slow performance/spontaneous reboots after turning VPN ON. However settings are 100% correct and key symbol is shown(used them before on this phone (as original XT1092 under 4.4.4) and using them on 4 other devices).
Sadly I cannot find anything in the logs which can point me for the reason of this bug (using OS Monitor for this). Somehow I have however the feeling this bug is caused by the conversion from XT1092 to XT1095 (while using a backup of the XT1092 4.4.4 modem). Can somebody let me know if this is a general problem, a problem that only appears with model conversions or a problem that only I have (because I messed up something during the conversion/lollipop installation ).
Thanks.

I just discovered that the lollipop update also broke all of my tethering options (just when I am stuck somewhere and need to do some work on my laptop)..
Guess I am forced to roll back to 4.4.4, anyone knows the best way to do this?

[Q] [Xperia V] [9.2.A.1.210] Unstable wifi

Hello,
I upgraded my phone to the unbranded/Nordic version (9.2.A.1.210) from the original 9.1.A.1.140.
While this brought many positives (support of BLE for my forerunner & good battery life), it also brought some negatives:
- A terrible clicking noise when the camera is auto-focusing (clearly a known bug in all JB version ...)
- A very unstable wifi
On this second issue, I have not seen any other report of the issue.
The symptoms are quite basic, after some time (around couple of hours), the phone will no longer associate with any wifi.
The only method I found was to enable/disable the airplane mode to restore normal wifi operation ...
I have installed wifi-fixer for having more details, since the wifi is looping on the association mode (could be authentication errors on these known network). Of course, all authentication info are correct as the phone will connect properly once going through the airplane mode ...
I also re-flash that firmware, from the .ftf but also forcing it from Sony SUS ...
At this point I reverted back to 4.1.2 as I'd rather have less features but reliable one (wifi is flawless now - well just as it should be ...)
Anyone else with the problem ? Any solution identified ?
Same problem Here
Would you please point me to the tutorials to get back my phone to 4.1.2, thank you?

Just follow the guide in the general section (i.e. retrieve the right .FTF file and use flashtool), this is very straightforward.
Tried with the ROM from Singapore, same issue ...
=> Association rejected on all known wifi
(using the power button to cycle the airplane mode restore the wifi for 10-15 mn)
Any advice on how to troubleshoot ?

Maybe it's your wifi that gives problem of compatibility when you're on 4.3
Try with another wifi if you can..
And try to change some settings of your current wifi like number of channel, kind of encryption, and so on..
In fact the problem is more complex as sometime my wifi appears to be ok but I do not have any connectivity ...
Now, I believe I found some interesting infos:
=> prb is directly tied with usage of Bluetooth (especially 4.0 BLE)
When the wifi is 'broken', disabling BT will indeed restore normal wifi operation ...
I could not notice the issue before since Android 4.1.2 do not support BLE ...
I've notice others thread reporting WIFI/BT issue (notably around support of smartwatch)
In my case, I'm trying to have my garmin GPS Watch to pair with the phone, this is were the prb can be easily reproduced
I have the same issue! That damned Association Reject!
I can confirm this is due to Sony 4.3 as Wi-Fi still work normally on my other 4.3+ devices (Nexus 7 2012, Galaxy Nexus)

Same here
i have tried numerous methods to fix this so far no luck..im on ub flashed 2 3 roms even stock rom with sus
One observation ...
This time, running stock .210 but not installing my BT4.0 Application (Garmin Connect), I only had the Wifi/BT issue once ...
I will install the application but not connect to my watch (Forerunner 620), to see where exactly is the breaking point.
After all these, I will certainly consider unlocking my bootloader and try the Omni ROM (as I see Walter79 is extremely active)

Wifi turning off when phone idle or sleeping

I've got an annoying problem with my phone where the Wifi turns off when my phone is idle or asleep. This means my WhatsApp for Web disconnects and also my Moto Connect plays up too.
I've got the same problem at home, work and parents house so can't be an issue with all 3 networks. The keep wifi on during sleep option is set to Always before anyone mentions this to me.
Phone is running Lollipop 5.0 in the UK and is NOT rooted.
I noticed it doesn't happen when the phone is charging though.
Any ideas?
Right I've now tried changing the Sleep setting to Never but get the same problem.
Also tried connecting to the router via WPS but no luck.
Router is a Superhub 2. I've ruled out that it's the Superhub as I have a Samsung Galaxy S4 Mini that is running fine without a single drop out.
Definitely something Moto X related.
I've also tried on both the 2.4GHz and 5GHz bands with same results!
Try looking within the WiFi settings on the phone. Mine has this

Sent from my HTC One using XDA Free mobile app
Mine is identical to yours other than the fact that I don't have the wifi optimization option.
Right I've just cleared the cache as instructed by Motorola support.
Still have the same problem even after clearing cache.
Ok I can confirm that the issue goes away when in safe mode.
This is starting to piss me off as I don't have any way of checking if it's an app affecting my wifi disconnections!!!
I've finally found and fixed the problem myself!!
I decided to turn my bluetooth on (even though it wasn't connected to any bluetooth devices). This seems to stop the phone from causing the wifi to go to sleep!
It seems like it's a bug in the Moto X Lollipop firmware. How do I report bugs to Motorola??
It's funny how most say it's apps that cause strange behaviour but for me it's been the actual Android firmware each time I've ever had an issue!
I hope it gets fixed soon.

It's a known bug of 5.0, and already fixed for 5.1. Source, at the "Bug fixes section".
Great that you found a workarround.
Cheers!
Manuel.
Hey glad to know it's a well known bug. The work around still doesn't work. It still keeps disconnecting all the time! Driving me mad!! If the 5.1 update doesn't fix it for me, I'll need to try and get a refund and go for something else. Shame as I really like the Moto X but I can't live with an issue as stupid as this!
I'm not sure Motorola are aware of this issue at all. See their comment below from one of their support staff I'm speaking to now:
Santhosh: We have not received any reports regarding Wi-FI issue after the Android Lollipop update but please give me a moment I will provide the solution for this issue.
His solution for the issue was to get me to do a factory reset lol. I already did this when I first got updated to Lollipop!!
Going to try doing another one now to see if it actually makes any difference. Then will install a few apps at a time or something.
I am connected to WiFi just about all of time, and I have never experienced this.
Right I've done a factory reset and started completely afresh with none of my data or apps restored. WiFi has been solid; I've not had a single drop out!
I'm going to install just a couple of apps at a time and keep an eye out if the issue comes back until I find the culprit.
Hi
My phone was perfect (until now) with the WIFI since november 2014 even after I upgraded it to 5.0
But today, it suddenly starts with this problem by itself. so I restored it to factory defaults with no luck, I installed a new firmware, and still has the bug.
So, why it shows up until now by itself without any mod, app or update?
Sorry for my English.
Today I upgraded it to 5.1 and the issue persists
I had to back to stock 4.4.4. and now my wifi has been fixed so far, working good without interruption until now.
I hope this has fix the problem from sourse, and I'll wait a few days to upgrade it again.
EDIT: Has been a month since my downgrade to 4.4.4. and my WIFI still rocks.
Just want to say that I'm having the same issue since the update to 5.1. Wifi is set to be always on during sleep, but I regularly wake up my phone only to find it connected to 4G, and switching to wifi a few seconds after waking up.
I'm on a locked bootloader (unrooted of course). I did a full reset after the update...
I'm sorry to say that I've seen more little glitches since 5.1 than anything I noticed on 5.0.
EDIT: another issue I'm having is the stock mail client not syncing saying that there is no network connection. My exchange account (push) works fine however...
Just to say the issue has started for me too since the update to 5.1.
I've done 2 factory resets but no luck trying to fix this very annoying problem.
Motorola have asked me to send my phone in for repair so I'll try that and see what happens.

lollipop update - issues

Hi
I have a question about lollipop update. Since i updated my phone im experiencing wifi issues because connection drops a lot. Especially while using tethering and sharing connection with laptop. Anyone has issues too? What can i do? I know some people suggested changing frequency but i cant no longer find those advanced wifi settings.
Update: So it seems that issue with wifi was mostly connected to tethering. I tried to figure out what's the problem but no idea..... Finally I tried to install Pda app and now it's running quite well and with reasonable speed again. Two things are still bothering me though. When I connected usb in the past I got a choice to connect phone to laptop either to import/export medias, tether or whatever else.... Now it doesn't give me this option and I didn't find it anywhere. So how do I connect phone to laptop so I can copy pictures, music etc? Also alarm seems to be off when I have 'silent' profile active. It used to wake me up just normally even with silent profile but now it says I have to set priority to alarm clock but I have no idea how.
Lg L90 serious problems with memory

So many quentions, so little time to answer them all...
Back from trying to be funny. Yes, LP in 5.0.2 has problems with memory (although I didn't know it still occured on stock since nobody else had reported it).
You won't solve this by unistalling apps. Those heavier ones will cause some problems in usage. You can go back to KK by flashing kdz file (a guide for it is to be found in general section) or wait for another update

LP does not have problems with memory is the ART runtime that is making the apps big
I solved the problem
I installed the app Fix lollipop memory leak and it fixed the problem
So no one knows about connecting via usb menu? In KitKat it always popped up automatically but I could also find it in the menu and choose to connect USB for media transfer (MTP mode) or tethering or whatever else. Now not only these options don't pop up automatically but I can't find it in settings. Anyone knows where can I find it?

"Unfortunately WiFi has stopped working" (Plentiful details included)

So I have the T-Mobile variant of the LG G4. I had it unlocked straight from the carrier a while ago and all seemed well. Recently I noticed a huge amount of battery drain and 4G LTE usage from T-Mobile's pre-installed apps--mainly com.tmobile.pr or something which is the "My Account" app (imagine being at 60% left with 27% of the drain having been an app and only 9% the screen. Yeah, it was that bad)
This I obviously found unacceptable, so I went ahead to try and uninstall the bloatware. Lo, much to my dismay, Tmobile has locked it down so you can't uninstall the bloatware, and you can only disable it. This alone irked me enough that I wasn't satisfied with just a disabling. I knew I wouldn't rest until I had obliterated it.
I've had plenty of android phones over the years and done my fair share of rooting and flashing ROMs and the like, but I hadn't touched that aspect of my G4 because I wanted a dependable device for school and I didn't want to mess around with it. I knew I'd have to root it to get rid of the tmobile bloatware so I went and did that using the Low effort root method (http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765). When this was done a lot of my background processes started to continuously crash. I decided to go ahead and put TWRP as the custom recovery and just go ahead and get some dependable 6.0 ROM, and I found a couple of them.
When I flashed the first ROM, the play store services were crashing so I found the google apps package for marshmallow and flashed that too. It seemed to fix the issue. Yet when I would click on my School's WiFi at the setup (which is WPA2 Enterprise) it would crash and say "Unfortunately WiFi has stopped working." I thought that perhaps I mucked something up in the flashing of the ROM, or that maybe there was an issue with the ROM in general, so I decided to just flash another ROM entirely (after factory resetting it all the way). Along the same time as this I found a slightly more modified and feature packed version of marshmallow by this lad here (http://forum.xda-developers.com/g4/development/h815-genisys-rom-1-0-classic-v10g-t3192649). I decided to go ahead and use this one since it had a h811 version there, that involved flashing a h815 and then flashing a patch.
The "Unfortunately WiFi stopped working" issue persisted, however. I found this odd. I then noticed that if I click any other network that ISN'T the WPA2 enterprise network my school is working that everything seems to work fine.
I went ahead and factory reset it all the way again in the hopes that would fix it. No luck.
I booted it to safe mode and tried to connect to the WiFi network from there. No luck.
I downloaded a third party WiFi app off cellular and tried to connect from there. No luck.
I can't enter the WiFi's name and try to enter directly because it crashes there too.
I can't "Forget" the network as it's never joined that network before so there's nothing to forget. It does let me enter the advanced options but a direct press causes it to crash.
So throughout ROMs and wipes and safe modes and all, this one issue has persisted, where my phone's WiFi will crash when it tries to connect to my school's WPA2 Enterprise network. I've tried plentiful fixes short of flashing back to a 5.0/5.11 stock (which I'm hesitant to do because I read something about phones bricking after they downgrade from Marshmallow using the .kdz files or something?).
I'd really appreciate any help that y'all can provide. I've read these forums for ages but this will be my first time making an account because I can't find anybody else with the same issue and its proving to be quite a pain.
tl;dr wifi isn't working with only one particular network and no fix I've tried under this sun has worked so far. help will be appreciated pls
Have you tried flashing this rom here --> http://forum.xda-developers.com/tmobile-g4/development/rom-g4-h811-xtreme-rom-v1-0-7-28-15-t3167667
I am using this one here and I have no issues using wifi. I cannot speak for the 6.0 roms because LG has not dropped the sources for the Tmo variant yet.

I got the brown leather variant from Tmobile and it only says H811 as far as I can tell. Not sure of if its the "n" version or not.
I have not tried that rom but ill be sure to give it a go, hoping it will help solve the issue. I did some additional testing and can confirm the issue lies with all WiFi networks that employ WPA2 Enterprise security.
Will there be any issue with the Rom when downgrading from Android 6.0? I was reading about phone's bricking when trying to downgrade certain versions or bootloaders on the tmobile variants.
I'm pretty sure going back to stock 5.1 will be fine. The Tmo variant hasnt been upgraded to 6.0 yet and the ports don't update the bootstacks. Read here --> http://forum.xda-developers.com/tmobile-g4/development/global-marshmallow-6-0-port-to-h811-t3232760
Update: It seems that any Android 6.0 flash cuts off the ability to connect to Enterprise wireless networks. I went ahead and flashed to the debloated stock rom on the thread you mentioned, but it cut off the ability to record video. As such, I went for the xTreme version that you mentioned, and flashed the camera restores and all.
Everything works fine now as far as I can tell. I also got rid of the Tmobile applications draining the battery and all that. All should be well. Thanks again for the help

WiFi disconnects constantly

It happens mostly when the screen is off (even though I have the always on setting enabled) but also when using the phone normaly. Suddenly I get a toast that I was connected to my WiFi. I've also checked the router logs an I see that the honor 5c is constantly disconnecting and reconnecting. Does anybody else have this problem? I'm on latest emui 4.1.2 without root or any other mod. I played with different channels and frequencies but that didn't help at all. Any ideas? I think it has to do with the battery optimization settings of marshmallow but even on the performance setting the WiFi connectivity just drops.
Whoever finds this will be my hero
In the wifi settings, just check that, "Keep Wi-Fi on during sleep" is set to always or not. If not then set it to always.
Edit : Sry i haven't read ur post properly. Is this the problem from the starting? Coz i don't have this issue.
I think I noticed this problem since the beginning but after flashing the latest 4.1.2 it got worse. Skype and WhatsApp calls get disconnected while screen is off (after 15 seconds or so).

The problem was with the original Rom and the reason why I flashed the latest.
Exactly the same issue.

Hello,
I have exactly the same issue. I checked also dhcp mode in the developer tools.
Did you found a way to solve it ?
Changing the router solved the problem.
