Hi,
- Stock (or custom) rom 4.4.2 works fine. Wifi turns on and connects.
- Stock (or custom) roms 4.4.3 and 4.4.4 hang on "Turning Wifi on..." and stay that way. (The rest seems to work normally).
I have the exact same issue with my Nexus 4, but my Nexus 7 (2012/grouper/nakasi) doesn't have any wifi issues.
Things I tried:
Complete factory resets, factory images flashed (KTU84L/P), flashed Carbon nightly (20140621).
Flashed the radio from and KOT49H factory image (there isn't one in KTU84L or KUT84P), flashed the bootloader(s) from the 4.4.2, 4.4.3 and 4.4.4.
I even tried deleting (or rather renaming) the /data/misc/wifi and /data/misc/dhcp just in case.
Router is not the problem, I already tried resetting it, despite all my other wifi enabled devices having no problems.
Nothing turns on the wifi on my Nexus 7 (flo/razor) or 4 (mako/occam) when on 4.4.3 or 4.4.4...
I am suspecting Google of screwing up, but if that was the case, why don't I see a whole bunch of posts with this problem?
I'm running out of ideas. The weirdest thing is that on 4.4.2 (stock and carbon last 4.4.2 nightly) it works like a charm! And even weirder, it happens on 2 or my 3 different Nexuses.
Which roms have you tried? I'm running Pac-Man 4.4.3 (6/19 nightly) w/elementix kernel and WiFi works just fine.

That helped, sort of... ElementalX 2.13 doesn't work for me either, but 2.12 does!
I will test some more, but I'm considering staying on this combo for now until 4.4.4 (or maybe higher) matures a bit.
I still find it highly suspicious that Stock is giving problems too. I found a few comments on 4.4.3/4 release news posts on the net with this issue too.
I'm on 4.4.3 on Nexus 7 2013 (LTE) and mine does "Turning Wifi on..." hang every day. I reboot and the problem is sometimes fixed. If I reset my AP and then reboot the Wifi always works.
This is relatively new. I associated it with a newly installed App, Wifi Scheduler, but maybe its not the App.
Interesting.
Thanks for posting your question.
PS: I'm on AT&T prepaid SIM card, FYI.
PSS: I just had a problem with my PC network access, seems my DHCP router issued a duplicate IP address. Unsure if related.
Whatever the guys over at Carbon Rom did, it fixed my WiFi problems! Thread is Here.
They put some special fix in their rom. Nightly of the 24th has the fix. Those on a deb/lte will be fixed in tomorrow's nightly.
I recently tried to upgrade to CM 12.1 for my T Mobile S4 being used on the Wind Network in Canada. But when ever the screen turns off it will lose connection to the cellular network, when i turn it back on i get a bunch of notifications, sometimes it will buzz 2 or 3 times for the same notification. I tried searching but can't find anything pertaining to this. i also tried other builds, Slim LP, Resurrection and the GPE but still all show the same issue
Has anyone seen this before let alone know how to fix it?

lollipop is known to be buggy with network on our device. Sometimes I even get sim card removed message and after a couple dozen reboots will my sim be recognized again. I suggest to stick with the rom that works flawlessly for you and skip lollipop, for now atleast.
And that's why I only root my phone, and run it stock. Roms always do this, no matter what anyone says. And I said this in my other thread, but ppl try to day otherwise. I told you guys lollipop roms are buggy for our phones. 4.4.4 for the win. Just uninstall bloatware and ur good to go.

So it's not just me with the SIM Card problem either. I got that so many times on lollipop and I tried to flash a 4.4.4 ROM again and it would still give me the SIM Card not detected. I was going to get it repaired again and I flashed stock MetroPCS tar and it got rid of the problem. I don't knowant if I would root again and just flash a 4.4.4 ROM and use xposed. I don't want that SIM Card problem to happen again. It's annoying.

I stayed with it for about a week before flashing stock firmware. Rebooted many times while I had it and it still happened. I've been on stock firmware for over 3 weeks and no problem at all.

No, I tried MD 1.3 and the stock T-Mobile ROM. Also forgot to mention I had a really bad problem with the Play Store. I couldn't install anything at all. I'd always get error 905 and this other number I forgot. No matter what I tried I couldn't get a fix, clearing cache, data, dalvik, uninstalling updates, reboots after each one and nothing fixed. Stock Firmware seemed to fix all the problems I had
Hello folks!
I recently found a strange bug on my Zuk Z2(Plus).
I was running it in AICP 20170901 build along with Orbot App. I had a situation when the phone started heating up and the battery drain became faster. As I was travelling and wanted to save the last ounce of juice, I deleted Orbot, to cool down the phone as it was continuously running in the background. My phone got switched off later, but once I was able to charge it, I tried connecting it to my home Wifi network. It just kept showing "Connecting" and later "Saved", but never connected. After repeated attempts to connect, it shows "Saved". Frustrated with this, I did a clean wipe and installed a previous backup of AICP 20170901 build which I saved a few days prior to this. But to my surprise, I was again unable to connect. It kept doing the same thing.
So, I did a clean wipe and did a fresh install of AICP 20170901 build and again, the same thing kept repeating. So, I installed the stock rom to check if it might work on that, but to my luck it didn't. So, I switched back to my earlier backup of AICP, and installed Dark Moon Kernel 004.1, But again no luck.
Between multiple ROM switches, it sometimes connects to the network and doesn't connect to the internet and then gets automatically disconnected.
Is there some fix to this. I think Orbot messed up something, and I am unfortunately not that tech savvy to find out what it did. Orbot is meant to replicate Onion Router, but landed me in a soup
Please advice.

Use some other rom... Recommended crdroid latest build... Use picogapps... And try again...
The issue could be rom related and even after trying new rom the problem still persists then it could be a baseband issue...
Try the recommended rom first with complete full wipe .. Good luck
Hi,
Were you able to fix this?
I'm facing the same issue. Tried several basebands and ROMS. Also, flashed stock rom through QFIL/QPST, but the issue is still there.
Thanks,

Were you able to fix it??? How did you resolve? After three years, I faced this issue all of a sudden after I changed my phone's battery, and tried everything with software but no fix. Any possibility that it is a hardware issue? How can it be deeply inspected to find the real cause of this problem?

Is there any fix found for this? or is it forever? Need help, need to give this phone to someone but can't fix this issue. Please help through any ways.
You may try resetting the carrier and wifi network. This may help.

Hi, I have the latest CM12 installed in my tablet, but I have a lot of issues, especially when installing multiple apps or if I try to change the Launcher. It gets into boot loop and there is nothing one can do but re-flash the rom, which is pretty annoying. It has happened to me already 3 times in a short while and I am thinking of flashing LineageOS. However, I hear it is still very buggy, especially the issues with wifi. So I would like to ask which is the least buggy Rom for 7.0 v410 or if there is a way to avoid CM12 from getting the problem with boot loop.
Boot loop has been caused when trying to change Launcher (because trebuchet regularly crashes), when installing x-plore file manager and in a clean flash when I attempted to install multiple apps at the same time. In all cases it got stack in boot loop, or would start only to restart after a while, endlessly.
Finally, I opted for LineageOS 14.1.
I had the 11-11 Nightly for some time and seemed fine. Today I updated to 25-11 Nightly. It feels maybe slightly laggy, but still checking it.
I have also installed "Best WiFi Keeper" app from play store and it generally keeps me connected. However, if connection is lost (e.g at restart or if I get out of range), I have to reconnect manually. I tried few apps for reconnecting but nothing worked. It appears that although the WiFi network is seen, the tablet cannot really re-establish the connection automatically.
I found Nothing stable yet.. In last few days, I have installed CM 12.1, same trouble.. I installed Tipsy and Tesle, unable to install apps from playstore. Tried CM 13 and Lineage OS latest build as you, Wifi Teathering and USB teathering not working and same problem with wifi connectivity. Keed posted if you find something better.. I shall too...
Tesla works great for me. I'm running a lollipop version that's still on androidfilehost; I'm not sure if GZR ever got updated beyond 5.1 for V410.
I've had CM 14.1 (long enough ago it was still CM and not LOS) on the tablet, and it felt like it would get laggy. That could just be from junk my kid installs though, but I don't seem to have that problem with Tesla.
I installed Tesla (Tesla-v410-5.1.1.High_Voltage.2.2.1-Release-20150902.zip from https://androidfilehost.com/?fid=24052804347807214) with open G apps but getting errors while installing apps from Play store(Some error code 963 - tried cleaning cache of playstore, play services download manager, removing google account and adding again - Nothing works). Same situation with tipsy. Any help?

That is probably what I'm running, I don't have my tablet right now. I think I flashed it with opengapps nano. I didn't have to do anything unusual to get play store to work.
Tipsy uses the same base as Tesla and Validus. Since it is persisting across multiple flashes and roms, consider formatting the internal storage if it isn't too much hassle, the TWRP wipe where you have to type "yes" to confirm. Sometimes some remnants in userdata that aren't touched by the normal system/data/cache/dalvik wipe cause problems like this and can persist the way you're describing.
Just make sure you have rom and gapps on an external SD or you have confirmed you can push files to the tablet in TWRP over usb via mtp or adb before you blank the internal storage.

I'm on Tesla, but it has the same base as Tipsy. I don't have data on the tablet so it isn't a 100% conclusive test, but it doesn't seem to work. The switch for USB tethering never turns on. Wifi turns on but never connects properly. My laptop does briefly show connection then disconnects with both USB and wifi tethering. It could be because there is no data connection on my tablet, but looking through dmesg on the laptop gives me the impression that something on the tablet isn't working right.

I'm on lineageOs 14.1 which is alright though the wifi issue is still there. However, someone may have found a solution, but I don't know how to implement it. Check posts 207, 210 and 215 in this thread: https://forum.xda-developers.com/g-...eageos-14-1-v400-lg-g-pad-7-0-t3583952/page22

Would you (or anyone who sees this) please tell me is it possible to flash TWRP if I'm on 5.0.2? Or must I downgrade first?
I'm rooted already. TBH stock is pretty solid and if the custom roms have too many bugs I might pass. But I would like to flash Viper4Android and don't think I've ever installed it without a custom recovery. Many thanks in advance.

I made the same question more or less, over a year ago here: https://forum.xda-developers.com/android/development/help-installing-cm-t3483074
You cannot flash another rom over lollipop and I've never seen twrp for android 5.0.2 for v410. I am not 100% sure because my question was a bit different, but I assume from the replies, that probably not.

Thanks. That's more or less what I thought. From what I'm hearing there are some bugs in the roms that no doubt aren't being maintained at this late stage so I think I'll stick with stock (would be nice to have a custom recovery though.)
Not that it matters (a year later) but lots of people root with Kingroot when there isn't another option and there's several ways to remove all the bits left behind and switch it to supersu.
Thanks again!
Well, I have a work around to stop wifi from disconnecting in lineage os. After that I did not know when wifi got disconnected and reconnected.
Just download E-Robot from playstore.
https://play.google.com/store/apps/details?id=com.bartat.android.robot
And set it to settings as per screen shot.

It works! Thank you so much! It seems the LOS developers have stopped trying to fix the wifi issue but it is important. The workaround even works at restart, with some delay, but it works!
Just to clarify to newbies like me, where ssid you have to put the name of the network you want to connect. I wonder if one can add more networks, so it can connect to any saved network according to where you are. You think that's possible?

That would be great.. I shall try.. if successful, I shall post results.
I have a uk410, the US Cellular variant of the v410. I tried the CM12.1 "stable" release cm-12.1-20151117-SNAPSHOT-YOG7DAO1K5-v410.zip found here (archive.org/download/cmarchive_snapshots), along with Open GApps nano for 5.1 (opengapps.org/?api=5.1), and quickly got the infinite rebooting issue.
I then switched to the Telsa ROM mentioned earlier in this thread (Tesla-v410-5.1.1.High_Voltage.2.2.1-Release-20150902.zip) found at androidfilehost.com/?fid=24052804347807214, again with Open GApps nano for 5.1 (build open_gapps-arm-5.1-nano-20180922.zip), and have been running it with no issues for two days. My wifi is connected, and stays connected (tested two different routers), Play Store and apps have been working fine, and no crashes so far.
I'm using TWRP 3.1 (twrp-3.1.0-0-v410.img).
Thanks for mentioning Tesla, @jason2678 !
So like all of you I was looking for a rom to install on this v410 7" tablet, and it looks like I should just give up or stick with 4.4.2 stock if I want to go through the rooting process.
Basically all the development roms end with the same problems, wifi dropping, hostspot not working, no ir blaster, volume problems, bluetooth errors, and several hundred posts about lolipop memory leaks crippling the tablet because of only 1gb mem.
So, I am asking all of you, is there any real reason to root it, besides going back to stock 4.4.2?
And lastly, is the stock 4.4.2 kdz image that is floating around a test version, and if so is there an actual official kdz image somewhere that isn't a test image?
Thanks...
CrDroid by far in my opinion. Lineage based, 7.1.2.
Also, e/ os has been unofficially released. No Google anything...an entirely new Google list operating system by lineage. It's lightning fast and runs magisk perfectly. It's basically like nothing you've ever seen before and if you look under LG g pad 7.0 on Android file host, go to the second page and click on the last user who goes by the name anonymous and you'll find the ROM there. I had no idea what it was until my g pad boot it up and I saw the e logo. I pretty much **** myself in excitement
Does anyone have issues with bluetooth? When I connect to my car it will reboot my phone in around 15-20 mins. I"m on crDorid now but it also happened on Syberia but everything was fine on stock global 12.5.2. I have already flash back to stock Miui and then reinstall crDorid rom, It still having the same issues. I have also turn off location scan for wifi and bluetooth.
Thanks
I have same issue but im in LineageOS, I tested ArrowOS and it was the same.
Swapped to evox and still having the same issue. I might just go back to stock rom.
I'll have to test it too.. I was bored to pair it to be honest but I'll do it to check it.
Not sure if it helps but I'm using another ROM with I think is not allowed on XDA (helluvaOS), and used a bluetooth headphone for 35min today, without problems.

Thanks for letting me know. I had to go back to stock because my phone was rebooting every 5 mins at some locations. But after I saw shadowam said that the banned OS was working so I gave that a try and its been good so far. Only 1 random reboot after using android auto the whole day.
