I had the same issue, I went back to the stock rom and rooted it doing the original ADB and fastboot method, could never get the 1 click to work correctly always ended up with an error on the wifi.
Lordao

I used the one click root on my wifi only and I received the wifi error. I re-ran the one click root ant it worked, just make sure when your running the on click root you don't click anywhere but the "OK" button and don't type anything it can goof it up.

all that the one click root does is type in the adb commands for you. It is literally the same process as adb. However, if you're running the one-click, you have to be PATIENT. Any clicks, any movements, even a gust of wind against your mouse, could cause the commands to miss the text box and that step wont work. I ran the one-click about 5 times before it got all the commands in; if I could do it again, I'd just use adb myself so I can troubleshoot as I go

GPS Not Working

I'm wondering if anyone else has had this problem with the SK4G or knows about any solutions. My GPS has been unable to get a fix since before I even rooted. I hoped rooting and installing a custom ROM would fix this but so far that is a no.

Try to fix permissions in cwm advance menu
try a nexus rom (the themes look amazing an are stable) only crashes are when something isn't supported or something goes wrong with a app
Also the root for the phone is like 99% good an 1% bad
If you have everything correct but can't flash "error" finding the command in the cwm its just a bad root easy fix just odin an reroot put recovery back in an there
If you have anymore issues please just reply to this thread I check all new replys to threads also please check a few other fourms with the same issues as more people helped to fix them. This phones community is pretty much dead or they play the mime game . Be silent an lock your self in a box type of mimes

Thank you for the help. I ran the fix permissions and rebooted and I am running a nexus rom, nexus jb 1.3.2 to be exact. Sorry, I didn't understand the instructions concerning the flash "error" as I am very new to it all. The gps did stop working even before I was rooted, I wonder if maybe this is a hardware issue.

No worries about responding right away, this isn't a huge issue just something I'd like to fix if possible. It is my only phone but I don't need GPS daily so no rush.
If you mean turn GPS off/on in settings I have done that several times. Most recently I turned it on and rebooted but still no GPS fix. Time is getting close to needing a new device lol...

[Q] Activation Problem - Boot Loop

So I sold an unopened, sealed Nexus 5 to someone last night and he's having a problem activating the device.
Here is his description of what happened:
"I popped in the SIM card, the loading proceeded as normally. It said it was activating and then a box popped up saying that "android is upgrading system files" or something like that. It restarted and went back to the language selection screen. I pressed English, next and then it went to the connect to wifi screen, froze and then restarted before I could even connect. Now it just loads on the boot"
I had him boot into recovery and do a factory reset, but the result is the same. I had him do a 2nd factory reset just be sure, but again, same result.
My thought is the system upgrade didn't happen correctly and not is corrupted.
What's the best course of action? Can I use the WugFresh toolkit to flash stock and unroot, or would I have to do it through ADB since the phone can't boot into the system?
I don't want to leave the buyer hanging, he seems like a nice guy, but I'm just not sure how to proceed?

Use ADB and flash the factory image for him.

That's what I figured. I'm not super familiar with ADB but can figure it out I'm sure.

Easy walkthrough:
1) Install ADB drivers (You can do it with WUG Toolkit).
2) Reboot your device in Fastboot mode (Hold up/down volume and power)
3) Download the latest HAMMERHEAD image from google website.
4) Download the Google SDK (not needed, but you will need Fastboot.exe, so I would recommend downloading the whole thing)
5) Unzip the image (.tar or .tgz I think) to the location where Fastboot.exe is (all the files should be in the same directory, usually platform-tools)
6) Double-click on the flash-all.bat file from the unzipped .tar or .tgz folder, should install stock image on your phone (note that you might need the latest version of Java installed on your computer)
And you're done.
Hope it helped!

Hello, I am the buyer of this Nexus device. I was able to successfully do these steps above, and reload the stock image for the Nexus 5. However, I am still running into issues.
WITH SIM:
I was able to get to the home screen after the initial setup, sent a few test text messages to my Google Voice number successfully, and browse on Chrome for a little bit before the device froze and restarted. After it restarted, I let it load up again, tried setting up my Google account on the device, then it froze again. All of the freezing happens within 3-5 minutes of using the phone.
So I decided to go into the bootloader, and do a factory wipe/cache wipe, and proceed without having the sim card in. I was able to get to the wifi selection screen, select my router, but as soon as the keyboard was suppose to pop up, the device froze and restarted. I am now just stuck on the welcome screen.
Any ideas now?
---------- Post added 29th November 2013 at 12:45 AM ---------- Previous post was 28th November 2013 at 11:56 PM ----------
Update: So I'm not sure what happened, but I ended up locking the device through Wug's Nexus Toolkit, inserted my sim card, and proceeded to set up the phone normally. So far everything has been working perfectly fine. I can receive/send texts, make and receive calls, and do normal functions with the phone without it locking up and restarting. Fingers crossed it'll stay like this.
Any idea on why this would've happened in the first place with the device?
---------- Post added at 01:38 AM ---------- Previous post was at 12:45 AM ----------
Update 2: Well, I noticed that it will randomly reboot every half hour or so it seems. It's kind of random, but I'm not sure what else could be causing these random reboots. The phone itself is working fine, but I just started experiencing random restarts.

Are you still on the stock rom or custom?

It was working fine earlier. I put it on the charger and got it to about 50%, used it for a little bit, then bam. It froze, and restarted all over again. I can use the phone maybe 5 - 10 minutes before it starts to recharge. Sometimes It'll automatically reboot after even unlocking the device.

I would do another factory reset and use it for a bit without any additional apps installed. If you are fully stock and locked with this happening I would think about possibly doing an RMA. Also just and FYI make sure you have the seller of your phone call and transfer the warrenty to you so if an RMA is needed you have the ability to do so.

I will try factory and cache wipe again, and see if that does anything with no apps or anything else installed, and go from there.

Sorry its happening. With everything stock and no third party apps or mods there to cause it at least to me things start looking like something bigger might be wrong here.

I think so too. No go after another factory wipe/cache wipe. It reboots automatically after awhile. I haven't had this kind of issue before, so I'm not sure what is causing it.

I figured it would be a sim card issue since it was working for awhile without the sim, but I did the factory/cache thing without the sim card, signed on via wifi, but it still doesn't work. So I am seeing what my options are from here. Thanks for all the tips everyone.

For some reason I wasnt thinking of this earlier. Can you capture a logcat from the device after a reboot and post that here. Should help track down the problem.

I was going to try and do that earlier. I will try and do that now, but I can't even get past the bootscreen animation at this point. The 4 dots will do the animation, freeze, and just reboot.
I'll keep trying. But, I really think this is just a defective one. I had a white Nexus 5 a few weeks ago and didn't have any of these issues :crying:
Edit: My last restart the phone kept vibrating like crazy before restarting.

Honestly it sounds like it's hardware related and time for RMA. OP If you do have ADB set up grab the last_kmsg right after the reboot.
Code:
adb pull /proc/last_kmsg
I doubt it will show any kernel panic but it's worth a shot.

From the sound of it he is now not even getting far enough to be able to pull it. I also think RMA is the best option here.

Just saw that. OP by your earlier symptoms I rules out a stuck power button. With the new info I'd look into it further. If the phone is just looping over and over it could be a stuck power button, Mash the power button repeatedly for a minute. Then try and reboot. A few other people have had this on the N5 already and it's a notorious issue on some Samsung phones.

If it comes to that, how do I go about transferring the warranty over?
I feel really bad, I just don't get it. I bought two of them, the other buyer hasn't had any problems. Both brand new, sealed, in the box. Go figure.

Maxx Hd Encryption unsucsessful bug

Ok so i was on my phone when all of a sudden my home screen kept crashing and pushing the window to close it. So i closed it and powered down the phone thinking a restart would help. It subsequently went to the Encryption Unsuccessful page where it tells you that your phone will need a Factory Reset. So i power down my phone and some times itll restart to the "E.U" screen 3/4 times. When i get it to power down and not power on i try to use the Volume+&Power. It'll pull to the menu and ill scroll to the Recovery and click it but itll push right back to the " Encryption Unsuccessful" screen. On the "Encryption Unsuccessful" Page i have a "Reset Phone" button but it does nothing but turn blue from gray when i press it. I can even take screenshots on the "E.U" page. I URGENTLY need my phone because im constantly awaiting interview calls and im waiting for a certain one. Will try other things until i get a Reply from this. If I fix it over night (well morning now) ill let you know with what stwps

sorry bout your troubles man, bad timing....i dont have a Max and I dont encrypt my phone. Are you on stock ROM? what version?
You most likely will need to flash with rsd lite, a stock rom then go from there

I was on the most updated STOCK ROM. And i didnt want to encrypt my phone either i think i may have hit that setting when my homescreen was crashing over and over. I was wondering if it could be heat damage because I have a laptop with a metal case (****ing Dumbass Alienware) and i was playing rust for almost the whole day and it gets like hot to the touch when i play that long and the phone was in my pocket. If you could link me to a tut for how to flash with rsd and a link to the stock ROM ill go through and try that tonight and post my results either in the am or right when i finish depending on what time it is and what im doing.
Another thing that sucks is theres no warranty and i have no carrier on it ATM (its a verizon phone without the sim, basically an android ipod)

its possible rsd may work, but i wouldnt be surprised if it doesnt. encryption errors are bad and sometimes unfixable.
if you are able to boot the phone and tell me the system version, i can provide an end all script to try.
if you cant get the system version, have you taken an update in the last couple weeks? that will tell me what you are on if yes or no.
also, you will need to be able to get into fastboot to use any script, you can get there right?

Encryption errors are triggered by the data partition becoming unmountable (data file system corruption?).
Data and data/media wipe (factory reset) could fix it (unless the data partition part of storage device is physically damaged).

Yeah i believe it may of been heat damage because of my laptop accumulating a lot of heat on the metal casing and that combined with 17hrs of Archeage = one hot laptop
And also for all who replied i sometimes get a picture of the little android dude laying down with his stomach hatch open and a caution sybol above it. Dont know if thats something bad or if its just buggy because i can hard reset it (pwr + Vol-) and turn it back to the encryption unsucsessful page.

regardless of the issue, "if it is fixable", this will do it.
there are certain situations that cant be fixed by rsd and standard fastboot. the above tool will fix any issue that is fixable.

Well, Putting myself in your place, the first thing I would try is boot into recovery and wipedata/ factory reset wipe cache.
restart and check again.
if even after that It doesn't work
flash firmware through odin.
although I would not be dealing with this problem directly cause I don't know what exactly is causing this. So the easiest part, flash.

Even after completely flashing to default through odin, I would say don't flash anything more. its not the software's fault
There are 2 things now
Your router settings. for this there are many things that could make problems
1. First Check wifi password and be 200 percent sure that you're entering the right password.
2. Check at another place, another wifi. I also had trouble connecting at my friends wifi, it would keep returning with authentication error, but the same device connected to mine router without any error. (I still couldn't confirm why it happened there, I suspect my friend had blocked my device in router settings or gave me the wrong password)
3. Forget network, turn off your device, turn off your router, then turn on your device and your router , open wifi in device enter password again and connect.
4. Make sure bluetooth is off and only wifi is on.
5. Check if your Mac ID is not being blocked by the router (find MAC address in your device settings-wifi-advanced) enter your Router settings >>wifi>>MAC Filter disable the Mac filter.
6. Go into your router and go to advance and under wireless go to wireless card list and click set up access list ...add your device with the mac address.
7. Reset the router.
8. Change the security settings on the router, from WEP to WPA2/WPA or vise versa, change SSID name as well.
can connect through WPA push button?
9. Try changing wifi channel to 5, 6,7,8.
10. there are few app in play store that say they can fix the wifi issues one such app is wifix, try them too.
Even after going through all this it doesn't work, then I feel there is a chance that wifi module is at fault and the part would need to be replaced.
there are whole lot of people on the internet that have faced issues and are facing issues with the wifi be it any device,(same goes for the wife ) Guess it has a mind of it's own too.
Well best of luck.

Ok Thank you very much for your help....
I already went through what u suggest before to post my 1st msg...with no luck.
What i find strange is that i'm not even able to connect to an open network..and
still i believe that it has nothing to do with the hardware....
Auth error on an open network is weird....anyway...
