My wifi won't enable after update - Nexus 6P Q&A, Help & Troubleshooting

Last night, my wifi just stopped working, it won't enable. When I go to advanced I am sometimes able to turn on the wifi, but it just continuously says turning on but won't enable, and sometimes it's just totally greyed out. I also had some problems today connecting to mobile data services as well, and I don't know if that's related.
I've tried a hard reboot (but it just comes up saying no command...), I've tried restarting it a million times... The only thing I haven't tried is a factory reset, because I am abroad using google fi and I am worried that I will have to set up my project fi again and I can't connect to a tower in the USA. (I am not sure if that will even happen, but I won't be back in the USA for a good few months so I don't want to risk it)
My phone says it updated yesterday, which I assume has caused this wifi problem (or a really big coincidence), but I can't find any information online about it.
I run the stock rom, it's not rooted, I have had no problems with any other things besides this.
Is anyone else experiencing this, or has experienced this before? Do you have any suggestions on how to resolve it?

It sounds like you are experiencing the same problem as everyone who forgot to update their vendor image after flashing the OTA. Had you been rooted, the simple fix would have been to flash the the MTC19X vendor image. With unrooted phone, I got nothing. The only possible solution would be a factory reset and to download and install the OTA again.

I don't touch anything or mod anything on my phones. The phone updates itself and as long as I am not running any custom roms I don't see why they wouldn't have a complete update that basically just spoon feeds my phone. Do you know if factory reset would reset my project fi?

I believe factory resets wipe the /data and /cache partitions of the device. All apps installed in /data are deleted, while apps in /system like project fi will have all its setting reset.
It's easy to resolve the iasue if your rooted, but since you aren't the next to last step you may try would be doing a network settings reset. Go to Settings>Backup and Reset>Network Settings reset. Just make sure that you are aware of your cellular data settings so you can set thing back up after the reset.

[Q] N7 4.4 update issues?

Not sure if I'm the only one, and if I am that really sucks, but I got tired of waiting for the OTA and decided to install the update via the fastboot method, unlocked my bootloader installed without a problem.
However the issue now seems to stem from transferring media files to my tablet, which I never had a problem doing, a pop up window will tell me that android.media.storage has stopped, giving me an option to report and to simply tap okay.
Not sure reporting ever does anything, and if it does I've never seen it change a single thing at all, but after I tap okay or send the report, any files transferring will just exit out, then if I unplug my usb and plug it back in, it doesn't seem to recognize the tablet at all.
I've so far remedied this, not sure if it's a permanent fix or temporary, by going into settings>apps>all, then from there tapping the app, clearing data and cache, restarting my tablet with a hard reset and it seems to be working for the moment.
However transferring files since the update are sluggish at best, and taking a 356MB folder of images used to take maybe a few minutes, 5 or 7 at the most, now it's hanging there at times with the transfer time increasing.
As a matter of fact I'm transferring said 356MB folder right now and it's stuck at 10 minutes to finish and hasn't moved for about 10 minutes.
If anybody else is having these problems, can you suggest ways you've fixed it? Or do I simply need to either do a factory reset or straight up flash it again to fix the problem?
Also, I made another article detailing my problems with updating, which I've since fixed obviously, but Recovery Mode isn't anywhere to be found, I do the regular method and before it showed the android with the red triangle and below him it would say no command, now it just shows the android with the same triangle with no wording underneath at all.
I've also re-downloaded the official factory image 4.4 from google's developer site and tried to manually flash recovery onto it, and it says that it succeeded but then when it goes back to fastboot and I choose recovery it loads then shows me the android with the red triangle.
I've even tried downgrading back to 4.3 but it tells me during the rewrite of the bootloader that there's a signature mismatch.
In addition, this should be the last revision to my issue, I've even tried re-flashing 4.4 and now that's kicking back an error saying there's a signature mismatch, so I can't go into recovery, I can't downgrade, I can't flash a recovery image to my tablet, I think I screwed up in ever updating to 4.4.
Im having the same problem with Media Storage when transferring pictures via Android File Transfer on Mac, tried it on Windows also, same problem.
It happens with my Nexus 4 on KitKat also!!
I still havent found a way to fix it, did you (OP) ever find a fix?
Cheers

Nope no fix yet, I haven't tried transferring a large number of files since, oddly enough, I finally did get the OTA update and it installed 4.4 again.
It didn't take long and the file size was puny, only about 32MB, I assume it installed what was missing, but I haven't noticed anything out of the ordinary since the official updated kicked in.
Yeah I have the latest OTA also, but I am still having the same issue!!

Not really sure why it's different for you, like I said I got tired of waiting for the OTA and manually flashed the factory image, that's when the problems started, but after a few days I got a notification that the new update was ready which really confused me.
But I installed the downloaded update without a hitch, booted like normal and I just finished transferring a 100MB folder of images to my N7 without an error popping up on my tablet saying something crashed, so I can only assume for the moment until I transfer a larger folder, that the DL'd update fixed the problem.
I've also heard people flashing it again, or side loading it, or even a factory reset would fix the problem, but there weren't many replies as to this actually fixing the data transfer problem.

Take anything I say with a grain of salt as I'm not the greatest guy to ask for help, I only really ask questions here and I'm just going to suggest what to do, if you do it is up to you and I take no responsibility for your device having further issues.
1. Hard reset your device and upon it rebooting, check for the update again and try downloading it again
2. If that doesn't work then back up your data
3. After backing up your data do a factory reset on your device and once you've booted back up to Android, check for the update again and install
4. If that doesn't work, I'm not sure what else to suggest, this is what I would do to try and fix the problem, but for my situation it was unique in that I tried fixing it various ways that seemed to make it worse before it got somehow better.
I hope issuing a factory reset works for you, if not then that hard reset does when you try to redownload the update.

Thanks for your reply back. Yep i also thought of the same 4 step solution as yourself but i also heard from 2 people that had the same thing happen to them and they thought it could be a goggle server problem, So i am going to wait to see if it sorts itself out over the next few days

Phone restarts at startup.

Well this is my 1st post so first of all hey everyone
I just spent a week in Amsterdam and my phone restarted twice, different times different days and I dont remember what I was doing with it back then.
But as I landed back home I put the phone back from "Airplane Mode" and went on to toggle "Cellular Data" on.
The second I pressed the cellular data shortcut on my the phone restarted itself but this time whenever it would finish the screen would be on but fully black and sometimes it'll show battery precentage at the top but then will restart again in an infinite loop.
Sometimes it'll pop up the "Optimizing Apps" window and will go through all 24, upon finishing it will restart once more and do the same.
I tried using the bootloader and it worked (the bootloader that is) but the phone would do the same thing even after Rebooting from there or shutting down from there and then turning back on.
I contacted tech support on chat but they couldnt help past telling me to go to bootloader and reboot, said I should factory wipe when it failed.
Also tried wiping cache but to no avail.
I have no backup of my phone (wanted to do one before the flight but got lazy and I suck for not doing one sooner) since probably October and google doesnt backup my contacts properly for some unknown reason.
I already downloaded Android Studio with everything included for me to try using adb to sideload stock without wiping but its my first time and I couldnt get it to do anything at all...
I already got the official stock .gz file from the motorola website.
Anyway here are the specs to my phone:
XT1575
Everything is stock. didn't root or change recovery once in my life.
Was fully updated and had plenty of drive space (I have almost 128GB with the 64GB version + 64GB SD)
I'm really lost here so help will be very appreciated.
Thanks in advance,
-Noam
Start with a full wipe and if that doesn't work flash the stock image. Not sure what your question is though as you never really say. Once fixed I would unlock and make a backup so you don't have to deal with this again.

The thing I pretty much want to know is if theres a way to either backup the phone now with it connected to the computer while in bootloader or recovery. or a way to flash the stock rom without wiping which I read someone did with his tablet. I cant post source normally because I'm a new user so here it is but change spaces to dots: schnouki net/posts/2014/08/13/flashing-a-stock-android-image-without-wiping-user-data/
Also while in recovery I noticed 2 options under wipe: 1. userdata only. 2. userdata+(insert something I dont remember here) and I was wondering what gets deleted in both? if I delete only userdata what data will remain? something helpful?
Sure you can try flashing without wiping data but being locked I personally wouldn't risk it. No idea about backing up in your state... somewhere I remember a thread on backing up without root try searching in q&a.

Out of curiosity why shouldnt I try flashing with no wipe if ill lose the data anyway? worst case wont I just have to wipe after it fails and flash again?
And I will try thank you
Do you have any knowledge about the 2 wipe options?
Thanks in advance
Well I tried turning the phone on and it took a couple of minutes before loading to a fresh start. It apparently wiped itself on its own. Managed to restore almost everything.
Anyhow the phone takes too long to boot now. Was even stuck at boot and I had to restart it.
Anyway to fix my software? Or at least check for corruption?

Unfortunately the process com.android.phone has stopped

I factory reset it and it stay pops up constantly!
Does anyone have a solution to this problem?!? Im willing to try anything. Ive tried all the ones on youtube with the "solution" but it does not work.
I am also running stock too
I also have this problem. Phone is stock, no mods
Is there a way to restore the phone without the built in factory reset?
I think the recovery files built into the phone may be corrupt...
Tried a factory reset and it didn't work

Hey there! I fixed this problem by actually rooting my phone! It went away right when I rooted it. It seems that it cleared the cache.

"Decryption unsuccessful" message on stock 7.0/7.1.1

This is the second time I get this message. First time was on stock Android 7.0. next time, ~2 weeks later on stock Android 7.1.1. To revive my phone I had to perform a factory reset twice.
What causes this message? Is it software or hardware related? I assumed the former, but the fact that it happened twice after a reset and on a new version made me wonder...
I'm heading to a country without 3G coverage and barely any WiFi, so if this happens then, I'm screwed on 2 levels: -Loss of pictures, due to not able to back-up -Not able to reset, since that requires WiFi.
Anyone else who had this issue? Any recommendations, RMA?
Full error message: "Decryption unsuccessful" The password that you entered is correct but unfortunately your data is corrupt. To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google account"
Thx.
You can set the phone to back up without wifi if you are good with that I've had my phone since December I have not had that happen odd.

Did you experience any random reboots?
When you say stock you confirm that it's full stock (no root and running google's kernel) ?

Never had any troubles with random reboots.
My phone froze, got unresponsive. I had to restart, and when it tried to boot I got this message. This happened twice.
No root, standard kernel. Bootloader not even unlocked.

That's it. Storage corruption and the decryption unsuccessful is a consequence of your problem.
Sorry but that looks like a defective device.
ram/emmc/power, it's hard to find without root/twrp. Unless an update got wrong but I don't think that would show these symptoms.
First, I would also raise a PR on google to see what they suggest: https://source.android.com/source/report-bugs.html
You really need to backup your data and have a backup phone in case the following gets you a brick..
I'd actually try flashing factory images (you won't be able to flash recovery image but others yes ). Make sure to record the messages returned on your PC to see if something went wrong. The update process is a bit dumb, it goes on even if errors are encountered so even if it finishes it doesn't mean much.
Once the device is flashed, if it boots, you could try filling your data partition by moving big files using usb transfer. When its full, reboot and see what's happening.
If you are short on time, prepare the RMA process...
edit: oh btw, I'm sure people would be interested to get the information displayed in bootloader mode (power on the phone by pressing volume down)

Thanks for your reply.
I sent it for an RMA, so unfortunately not able to do what you described. Couldn't chance it getting this error message when abroad.
Curious though if they will grant an RMA, nothing much is looking wrong at the moment. Hope they will, because else I'm screwed.
If they don't, though, I'll see if I can get the information displayed in bootloader mode.
I'm having the same issue.
Same message, only I'm BL unlocked, rooted and twrp.
It happened twice. Once on 7.1 DP1, and again on DP2.
Once I get into recovery, the system is encrypted, and I can't do a thing.
I'm going to try and back up to a flash drive, and try to mount that in twrp if it happens again.

Recent Twrp now supports full disk encryption so you should be able to see your files? And even do a backup from there. Take twrp 3.0.2-3

Weird. I don't have twrp so I can't check but you should see your data. Maybe the partition needs to be mounted (I think it is by default though). No /data/media ? /sdcard is the same but as a virtualized FAT file system to be able to be access from Windows. Could be that /sdcard is empty in twrp but /data/media shouldn't.

If I understand this thread flash custom kernel like ElementalX to unencrypt your device.

When WiFi is turned off I get 'Unfortunately System UI has stopped'

This is on two standard Galaxy S5's, with standard ROM, etc - not rooted, or anything else.
Every time I turn off WiFi, or enable Mobile Hotspot, I get 'Unfortunately System UI has stopped'.
To fix I have to Power off/on the phone.
(Turning on WiFi is no problem, just turning it off.)
I have gone into 'Safe Mode', and same issue, so it looks to not be a bad App.
I have also uninstalled 'Google' updates, and again no change...
Any thoughts?
All of a sudden my S5 showed the exact same error message for no aparent reason... I didn't do anything, and now I can't use my phone at all because of that bug. It happens on every boot so I can't even unlock my phone. Tried reinstalling everything, ROM, recovery, kernel, with/without root = still same, what just happened here??
EDIT: Same thing if I'm in Safe Mode -_-
Seeing noone knows a solution here's what I did yesterday.
1. Backed up all my stuff from internal storage to the sd card
2. Did factory reset in TWRP recovery
3. Flashed completely stock official firmware from Samsung
4. Waited for it to boot up and try to restore some of my settings (it restored all folders on their places, made same amount of home screens as I had before the reinstall and downloaded all of my previously installed apps from the Play Store, ofcourse without the cracked ones, and it also restored most apps' data as well so it's not as bad as you may think to factory reset and reinstall everything)
5. Started rooting, flashing TWRP again, installing Dolby Audio, Xposed and everything I had before, took me one full day to set it up as it was before.
Now when I set it up I always make a nandroid backup from when things are working fine, in case it goes crazy for no reason again... Good luck!
when the wifi radio is acting weird, a dirty flash of your current ROM susually fixes is as its probably a radio issue. Id do that before doing anything drastic like the boot-n-nuke Odin flash and starting from scratch (which will fix that issue)
I don't think I have a ROM issue, as I have two S5's, and both have the same issue... and both are standard ROMs.
I will do a factory re-set on one at some point, but this looks to be a 'simpler' issue.
I have tried a full Cache delete, as well as other 'clean' processes.
Nothing works.
I tried to re-flash my stock ROM as @youdoofus said but still had that annoying popup. Try everything you can think of, if all else fails, reset.

well, you can wipe cache, and dalvik 3x each (not kidding about the 3x each), then dirty flash the rom, pray to the gods of android, reboot. If failure occurs, its Odin Nuke time unless you want to try to flash an individual radio file by itself (not recommended)
