HELP XDA! Phone Reboot's if using 3g Data

Hey,
My AT&T rooted nexus one is still randomly rebooting if I use 3g data. I am in Costa Rica and the 3g is on the 850 band. I also have to add the apn "kolbi3g".
So basically I can use the phone for anything and it works great, but if I add the apn and start using the 3g heavily I will get a reboot, sometimes it will reboot vibrate 7 times and I have to pull the battery. I have tried 2.1 and 2.2 rooted and not also cyanogen 6 all the same problem.
If I do *#*#4636#*#* and select the wcdma only it runs the 3g better but reboots way more, sometimes the instant I place load on the connection. However if I select wcdma "unkown" the 3g works much better I can use it sometimes 30min at a time without a problem.
So any ideas what I could try? Is there a kernel that will up the volt's a bit just help stability? Or anything else I could try? Data roaming is off, I have tried both off and on, no difference that I can tell.
Thanks a lot this is driving me crazy! Just got this phone Sunday too sick to my stomach of the thought I spend $600 on this phone if I can't get 3g to work

How about radio image???
It is currently on baseband 4.06.00.12_7. Is there a more current radio?

I came across this multiple reboot issue on a (locked) Vodafone UK Nexus.
It booted into the OS (lockscreen) and as soon as data connected it looped back to the last couple seconds of the animated Nexus logo.... and again.... and again.
I powered down the unit (battery pull), booted into bootloader (voldown+power) and selected clear storage (voldown,voldown,power) then (volup) to confirm.
This deletes the user data and you have to sign in and set up the phone again but it certainly fixed the issue. My only guess is some user data became corrupt and the kernel panicked and forced a partial reboot.
Give it a try and lemme know.

Just did that (had the phone plugged into wall charger), and the second I got to the home screen it rebooted then vibrated like 6 or seven times. Seems to do it worse when it is plugged in. And now it won't even boot up even after pulling the battery, it vibrates 6-7 times.
I am really worried about this, any other ideas??? I will try anything! Thanks for the help

Update! Now the phone just reboot when I do anything period with it plugged in. Just like posted in another thread on this section!
Please any ideas I am very desperate and very sick to my stomach!

Hmmm very strange.
I'm aware from what you were saying on the other thread that you've got an unlocked bootloader and you're wondering what to do on the warranty front.
If you've really tried different combinations of stock and custom firmware and having the same issue I'm tempted to say its a hardware issue.
Many people have returned their unlocked phones with no comeback from HTC some have reported that they have noticed the unlocked bootloader and have issued a motherboard repair as part of the fix because of this.
Although im unsure of the additional cost (if any) i would definitely recommend going through the warranty repair route with HTC. They won't say no and send you back the same broken phone. And who knows, if its a confirmed hardware issue they may just replace it as a goodwill gesture.

Other than that I don't have any more ideas.
A nexus support thread has a popular answer referring to the clear storage fix.

Just make sure you are definitely clearing the storage FROM THE BOOTLOADER before calling HTC. It is the first thing they will make you do before accepting a return anyway.

Ok thank you so much sir. I am so glad to hear that I may still have a chance at getting it replaced! It was very fullish of me to unlock it, I know, it is just that I figured it was software and could be fixed by unlocking. It is going to cost me $$$ to get this to the States, but that is life. If I still can't get it to work I will call htc and let you know what they say

Little update here. I cleared storage again and just simply disabled data, I have been using the phone for a couple of hours on work without any problems. Next thong I am going yo yty is another friends 3g similar card and see if it still reboots on that sim, if it does then I am calling HTC.
Also still open to any other ideas you guys may have.

[Q] Wifi not working any more

I'm hoping someone can help me. I installed CM KANG 7.1.5 on my Milestone a couple of months ago and for the most part, everything was working great (at least better than the stock 2.2 on it). But over the last week or so, I've been having a problem with wifi on my phone. Basically, wifi is not working any more or at least it's inconsistent now.
Previous to this week, I had no issues. I had a number of wifi networks set up, and everytime I went to the wifi hotspot, the phone would automatically switch from using data to wifi.
However now, it appears the phone doesn't detect wifi networks any more. I've tried multiple hotspots and still nothing. I've tried using Wifi Analyzer and doesn't see anything either. I've rebooted the phone multiple times, taken the battery out, reseated the SIM card and still nothing. I use 3G Watchdog and Juice Defender and have removed both and still nothing. The strange thing is it's sporadic. ie. wifi will work one day and then the next day in exactly the same spot, the phone get no wifi at all.
Has anyone else experienced this issue? How did you fix it? I've thought about wiping the phone and starting over again but I'm hoping to avoid that, if possible.
Thanks for your help in advance.

Doing a complete nandroid backup, wiping everything, and installing a new ROM takes me a total of about 15 minutes. If the problem I was having isn't fixed by that, I just restore the backup.
I should also point out that 7.1.5 is outdated and the current version is 7.2.0; quite a bit of work was done on WiFi issues in the past few months, and you're probably missing out on fixes for these exact issues.
It can be a pain to set up a new ROM, but worst case scenario is that it doesn't fix anything and you can just restore the backup and be right back to where you were an hour ago.
Please keep us updated here.

Sorry, I'm somewhat new to this (this Milestone is the first phone I've ever rooted, installed CyanogenMod, etc) so I'm probably going to ask some very noob questions here. My apologies if these are very simple or dumb questions.
I've been hesistant to rebuild/upgrade my phone to fix this problem for a couple of reasons including -
My wifi still comes and goes randomly. I worry that maybe it's a flaky hardware issue more than software so I don't want to spend all this time rebuilding it again to find out it's a loose connection or something like that instead.
I assume all my apps, data, settings, etc will be wiped out if I rebuild or update my CyanogenMod unless I use something like Titanium Backup to back them up? Or is there some better/faster way for doing it or maybe CyanogenMod and Nandroid have some better/faster solution that I don't know about? It took me, it seemed like days, to fully restore all that stuff last time so I want to make sure it's worth doing.
Is there an ETA on a "production" aka non-RC version of 7.20? If it's coming soon, I'd rather wait. I'd hate to upgrade to the RC version and then 2 weeks later have to do it all over again.
Thanks for your help.

About ugrading to 7.2:
- do full nandroid backup first
- clean both caches
- apply 7.2 zip
- clean both caches again
- rebot
I use that method when moving from one version of the ROM to another and no serious issues (one or twice I have to clean caches one more time after first restart). In worst case you have nandroid backup so you can quickly move back.
I have done full wipe (including partial sd and complete ext partitions cleanup) just few times e.g. moving from CM6 to CM7.
Generally I apply full wipe only when moving from one ROM to another, in beetwen versions of the same ROM I just clean caches twice.

Freezing problems when on WIFI. Please Help!

Hi there,
Okay, so I have been facing this weird and annoying problem(makes me sometimes throw the phone towards the wall, thanks to AHD solid build otherwise it must have been broken by now). Whenever I turn on the wifi and connect to the network, my phone hangs and freezes for like 10-20s and then restarts. It first started happening around 4 months ago and I have owned this device for more than a year. I cleaned flashed the stock rom again and it was fine and a week later it all started again. And the process of me flashing(Clean flash) again and freezing problem has become a loop. I have clean flashed like 5-6 times in these 4 months but the problem persists. I know some people say that this issue develops when there is a shortage of ram but I use the basic apps which I have been using for years. I clear my cache from time to time and have enough internal storage capacity always. I also have around 250-300mb free ram on average.
I have tried cm11, Validus, Lollipop roms on my AHD but they always have some bugs which makes me stay away from them. I like the fluidity and stability of stock therefore most of the time I stay stock.
Just yesterday when I connected to my home wifi the phone froze as usual and restarted. On restarting it automatically connected itself again with the network and froze and restarted again. This continued for like 10 times in loops, after which I immediately went into the settings and turned off the wifi as the phone restarted.
Please help me out, the phone has become unusable for me.

One thing more, I made a nandroid backup of stock rom JB 4.1.1 AT&T the very first time I flashed a custom rom on my phone and after clean flashing(format system, wiping cache, wiping user data, dalvik cache) I restore the rom from that backup. Basically I have never flashed the rom through RSD Lite.
So maybe I should try flashing with RSD Lite and see if the problem persists?

Seriously, would anyone care to help?
Or I'm just wasting my time here? Isn't this community built to help people?

It's not a problem I've had, but I'd say start from scratch. Go back to stock, then re root and try again.

Thanks. I'll try. Hopefully it would fix the problem

[Q] Wifi stuck "Turning on"

Tried searching around and have seen others with this issue but nothing has worked. Tried a clean flash of a rom and during the setup wizard its still broken.
I have pretty much done everything but done a clean flash of stock and i am gearing up to do that but i dont have high hopes.

are you using a custom kernel?

Nope...
its not that i just cant connect, its like the hardware is broken.

and just did a complete factory image flash.
still broken

I had this happen to my N6 last week. It started after running the battery completely flat so the green LED lit when I charged it. The fix having repeatedly wiping seemed to be draining battery completely again until the green LED lit when I charged it. It has worked fine ever since.

I have the exact same issue and have tried everything from fully returning to stock which worked a little better but still not well and also tried different radios etc etc and roms... dont know what the deal is.. nothing on the internet seems to help its almost like no one knows how to fix it or its really rare... ugh

First contacted square trade as that is my insurance, they said contact Moto because it is still under warranty. Did that, Moto said they would replace it. I said i don't want to go without a phone and they said they can charge me 25 and put a 500 hold on my account but they would send the phone first. Said OK phone arrives on Tuesday.
Just as an FYI they did basically say did you factory reset it.... but that is all the trouble shooting.
If anyone is interested in my symptom. Wifi is just always stuck at "turning on" every once in a while it will be off. but when you try to turn it on it just gets stuck again.
When it is stuck you can not turn it off.

Might be worth an RMA. see my previous post.

Don't know if I'm a little too late to this post... .But it happened to my Nexus 6 too, tried everything, wipe cache, factory reset, root, delete /persist/wifi but nothing worked....
However, luck seems to be on my side when I went into Google Connectivity Services under Setting--> Apps... and wipe its cache and tried to disable it (but stopped before I did). Then reboot the phone once i wiped all the data from the Google Connectivity Services Apps and VIOLA! It's working now!
*EDIT... It worked for about an hour (allowing me to dl all the apps) but now it has failed again....

I have the same issue as soon and I unlock the bootloader

any ideas? Im going to root again the device and load a different to see if it makes any difference

I am experiencing this as well. Was working fine yesterday and when I tried to go to Android M Preview 3 this happened. Whats worse is that this is happening right after I switched from Unlimited Data on TMo to Project Fi with 3GB. Making this even more frustrating is that Project Fi support says the preview images are now compatible with Project Fi. Isn't that something they should be telling people up front?!

I'm having the same issue on marshmalow, it suddenly started to happen some weeks ago.
First times was solved with phone reboot.
Then was required to clean cache before restart
Now I've tried reclutance suggestion (delete data from google connectivity services and reboot but the problem persist?
I'm using 6.0.1 stock rom without root
I don't want to perform a factory reset
Any suggestion?

here too...close the wifi

All tried doesn't work,
Wipe cache
Wipe dalvik cache (via fastboot as I do not have a custom recovery neither unlocked the boot or root, my phone is completely original)
Also tried to delete wifi data
Any suggestion?

RMA

I'm continuing to have issues with my Motorola Nexus 6 phone.
It is running stock android 6.0.1
I never unlocked it or rooted (Sadly cause If i do so I were able to backup my apps and settings with titanium backup and restore it before a full device reset )
The problem started some weeks ago.
First symptom was that i was unable to enter on Settings -> Data usage (Every time receives an "unfortunately, settings has stopped" message)
Then some days have difficult to connect to wifi or disconnect (at that moment I didn't investigate the issue, just retry considering the issue was on router side)
After some time I realize that the problem was on the phone, specially cause it started to stuck turning on wifi, but for some days just turning off phone and turning it on again solves the issue.
With the time it becomes more and more frequent and turning it off and on didn't solve anything so I've reboot into recovery mode and perform a clear cache but it doesn't solve the issue.
Looking here and at other forums found that this issue is really common and some people solves it trough ADB with "adb shell pm clear com.android.settings" I've tried it but it didn't solve anything.
Even when many people didn't solve it with a factory reset I want to try it, but I need to be able to backup one app data (If could backup everything will be the best but at least need to backup blockchain app (Also have an issue with them as provider and couldn't log in from another device or website, just this device has a session already approved and open)
Any suggestion?

I've upgraded/downloaded to almost any possible rom and the problem is still here
Looking on forums found that is a very common issue since marshmallow in many devices (Specially Nexus)
Most people couldn't fix it but some could.
the problem is with devices macaddress that shown 02:00:00:00:00:00 and get stuck turning on
there are solutions in forums that seems to be a little bizarre like drain battery to 0 and full recharge (This one works for me once)
,others like deleting Google connectivity services cache, or deleting /persist/wifi folder completely
But I found one for nexus 5 who replaces the full /persist partition with a dump and edit the files and permissions with macaddress information.
This seems to have logic and provides an explanation about why the problem persist after, factory reset or rom changing so I want to try it in nexus 6.
Could someone provide me a dump of it?
There is an app: https://play.google.com/store/apps/d...nam.partitions, that makes the process of making a partition backup easy. The persist partition is on /dev/block/mmcblk0p26
Thanks in advance

Did you solve your problem? Because I have the same. Did you try to change Mac address on device?

Some issues I've had (2 days in)

Love the device, but this one is going in for an exchange. Not sure if it will resolve the issues I had, but my phone was behaving badly. I unlocked and rooted it about 10 minutes after I got it, using the Chainfire method here..
1) WiFi reception is awesome, except it drops the connection constantly! I have an entry level commercial AP (Unifi) and the thing is awesome. All kinds of devices connected to it, but this Moto can't stay connected. From the logs on the controller, it appears to be switching channels constantly. Wifi goes from all bars to bars with x to off.
2) Reboot results in bootloop. On more than one occasion, I had to reset the device multiple times to get it to boot. This morning, I could not get it to complete a boot at all. I've since reflashed the Tmo stock ROM.
3) Lookout randomly comes back! Froze it with TiBu, stop and disable in app manager... nothing kills it! Reason 1 for root!
The WiFi issue is a killer. Again, I am going to take this one in and exchange it for another and hopefully the WiFi issue is gone. I think I'll need to restrain myself from rooting until I pass the exchange date.

I had similar issues what i did was flash the stock boot img then do a factory reset and reroot and everything is good now

Thanks! I will give that a shot before I take it in.

I've been back on stock with unlocked bootloader for a day and change, and I still get WiFi drops. It seems to happen more with BT on, but they certainly haven't gone away. I've changed a bunch of things on my AP to try and eliminate them too, but it hasn't helped much. I may try disabling the A/C radio (which fixes it for some), but that's hardly an answer. I am starting to think that this is a Nougat or a Qualcomm issue.

Seems like a hardware issue. If it was a software issue then it would affect more than just you. So far you are the only person on various forms I go to having issues.

I actually have this issue with another device too , so I think it's either an Android, AP or a Qualcomm thing. Some have said turning off the A/C/N radio helps, but that's not a "solution."
