Xoom MZ601 Rebooting on 3G with Nightlies #45 - Xoom Q&A, Help & Troubleshooting

Hi All,
Fairly new to all this. I rooted my Xoom on the weekend, loaded CWM on and loaded the latest Everest Nightlie #45 onto my Xoom MZ601.
Everything looked good for a while as i was loading all my apps etc on while on my home wireless network.
I then left home on Mon and it of course converted back to 3G on Vodafone, but then the tablet started doing all sorts of wierd things. It would spontaneously reboot, reboot into Recovery and my favourite just freeze the screen and do nothing.
As soon as i turn on Wifi (and connect to a network) and get off 3G or run in Airplane mode, the Xoom runs stable. I can't see any settings to modify on the 3G Network side of things, so not sure what i can even try..
I haven't yet had a chance to try stock 1.0.0 or any other nightlies as i didn't discover these issues till after the weekend when i left the house and fell back to 3G (and just haven't had the time yet..)
So has anyone else seen this ? Would any particular logs help trouble shoot this as i can "very" easily reproduce..
Appreciate any comments or feedback.
Regards
Van

Do a full wipe, and reflash ROM and GAPPS then reboot - this can usually fix any qwirks.

But the whole point is this is a brand new full flash with full clear of the caches and full wipe/reset of the device.
I'm happy to give it a go on the weekend, but i would have thought this is the cleanest it would get ? And considering its a reproducible issue...

[Q] Liquid 3.2 = dead wifi/gps

I just upgraded my Droid X to Liquid 3.2 (full SBF to 602, ota'd to 605, rooted, then flash to Liquid). I love the ROM, but it appears that my wifi and GPS are now broken. Wifi tries to turn on but then turns back off after a second or two; GPS won't even attempt to come on. Anyone know a fix for this?
Edit: I rebooted into recovery, wiped cache and Dalvik cache, and tried again. Now the GPS appears to be working, and the wifi stays on. However, when I try to connect to my home network, it drops off after a second or two (once it connects, it keeps scanning, and then it disconnects). I logged into my router and saw that my phone was briefly hitting it, but all the router log showed was the transfer of an IP address, nothing useful for troubleshooting. Does anyone know of a log file on the phone somewhere that might indicate why it keeps dropping off of my wireless network (yes, I've double checked the password, and yes, the wireless network is functional right now).
I'm out of guesses at this point, so I'm hoping someone else can help me out.
Hm. It gets curiouser and curiouser...
I've been tinkering throughout the day, and if there is any generalization I can make, it's that between wifi, GPS, and airplane mode, one of them (occasionally two, but never all three) will work at any given time, but every time I reboot a different combination starts working. Go figure.
Help anyone?
you got same problem i got. let me know what you figure out. I will post if i figure it out
I could not figure out wifi, so I went to vortex. I like the liquid but the wifi is a big problem and I did not have a lot of time to mess with it right now. I may by another droid x just to mess with things of this nature. If anyone comes up with wifi solution please post.

[Q] CM10 Wifi issue

I searched around and couldn't find anything. Maybe I over looked it if so my apologies for a repost.
I have CM10 on my phone. 99% of the time I keep my wifi off and don't use it. About 2 weeks ago I tried my wifi and it won't turn on. I know there was a problem with the nightlies after the 1007 one, at least I think that's the right one. What I can't find is if the wifi issue has since been fixed. I'm on the lastest nightly and am still not able to turn my wifi on. I just wanted to check and make sure that this is still a problem before I go ahead and try a wipe and install again. I'd like to avoid that if it's not going to work. So is wifi still an issue? Is there something I can do to fix this? Any help would be greatly appreciated
EDIT: By not working I mean the wifi slider is greyed out. So attempting to slide it to on results in it immediately defaulting back to off. Also I tried changing the wifi setting from Europe to US but that never seems to save.
I did a factory reset and installed the rom again. I'm still unable to turn on my wifi. Can anyone offer any assistance?

[HELP] Unstable 3G / 2G

I hope you guys can help me out with a problem. Sorry about the long post ahead, I'm just trying to give as most information as possible.
Introduction: I recently installed the latest releases to see how jellybean was coming along on the Desire S. I flashed PACman and then CM10. I liked them a lot, but I usually prefer to wait until a final release, so I reverted my backup of CM7.2. One week later I notice my internet connection is very unstable, I don't know if it's my carrier's fault, or the upgrade messed with something and the backup didn't restore, and reflashing CM10 changes nothing. I didn't notice any problems right away after testing the other roms, but like I said, everything happened around the same time frame.
Problem: First of all, if I enable 3G, it will almost never connect. Sometimes I get a 2G connection, but most of the times there is no internet at all. On 2G only, it seems that a few minutes after screen-off, the connection drops. Only after I wake the device, it realizes the connection was down and resyncs with my google account. And even while awake, 2G is still very unstable, I get numerous network errors on the facebook app timeouts on google play.
Device info: Should I test other radios? I noted that it came from the factory with 3822.10.08.04_M, and was on 20.28b.30.0805U_38.03.02.11_M (I don't remember when that changed, I don't think I've ever explicitly changed a radio). Now I just flashed 3822.10.08.04 back, but it didn't change anything. Could HBOOT also have any influence the problem? I remember I downgraded do 0.98 so I could S-OFF using Revolutionary. Now I'm on 6.98.1002.
Lastly, probably a logcat would help. How should I go about doing it? Reboot phone, wait for it to connect, put it to sleep until it disconnects, wake it up, wait for reconnection, then logcat? Since the problem persists both on CM7.2 and CM10, I decided to stick with 10.0 (nk111's cm-10-20130109)
Thanks a lot in advance!
Here's a logcat I took today, if anyone is willing to investigate. Started recording after gtalk was online, turned off the screen, waited a bit, turned it back on and checked that gtalk was offline.

I'm having similar issues on Pacman 18 and 19.3.
My connections seem stable, but I cannot switch between 2G and 3G without rebooting. If I don't reboot, the phone has no internet connection.
Also, on 3G, battery life is very bad.
I'm wondering if it would help to flash a different radio. I never changed the existing radio.

modem_err - signal loss - random-reboot - high battery drain

Hi,
my phone lately shows an high battery drain, random reboots and signal losses.
Aside from supersu and adaway everything is stock. last-kmsg shows "modem_err"
A few days ago I updated my phone from MMB29V to MOB30H, right after this I went on holiday. (left country)
While being there everything worked fine.
But right after I comeback home the phone started to act strange (see title).
Anyone an idea what could cause the behaviour?
Maybe the update? And I didn't noticed it in holiday because of my disabled data connection?
I tried:
a full wipe, reflash of stock image
flash of old radio
looked out for wake locks (there are non)
using phone without apps (only stock)
Might flashing old bootloader/kernel help?
Maybe interesting:
My provider (Klarmobil (T-Mobile DE third-party)) tends to switch my network mode between 3G and HSPA,
from what I heard and see this depends on my data usage. (HSPA while surfing, 3G while idling). I have the "feeling"
it disconnects when it tries to switch.
Thanks for your help!
Edit:
Added another set of logfiles, showing a "signal-loss", it got so far to ask for my pin again.
Sadly errors still keep happening. I tried the march build and also a custom kernel, no change :crying:

Wifi problem - on-off and no wifi hotspot, phone restarting - Please HELP

Hello everyone,
me and my wife enjoy our htc U11, but few days ago mine start playing up - wifi have difficulties to connect its doing like on-off-on-off, and after while connect to router, doing same thing at work and home too, and I really can't use any longer wifi hotspot, and phone restart at least once a day, not very happy, but today my wife experienced same problems as I have few days, must say both phones bought in UK from two different companies and different times, both are on stock rom, completely standard phones, I am only using modified camera apk, can anyone give me advice what it could be?, I do not have even Facebook or Twitter account, so can't be related to these apks. Was going to do hard reset tonight, but after my wife told me she got same problems and she use her phone very little, I am not sure if hard reset will resolve problems. I will welcome any help...
Forgot to say we are on 2.33.401.10
Many thanks..

Have you reset the router, checked the network settings are correct (if you use dhcp just reset your router).
If the ssid has spaces or characters/symbols then this can cause issues.
I have personally known routers that use signal binding to run at speeds incompatible with some devices. Especially those with 1gb interfaces. *cough netgear*.. Falling back to a basic setup helps significantly.
A factory reset will probably solve it but you'll lose your data. That is the last ditch effort.
Hi, what is latest update for this rom?, as we can get no ota update, if you point me right direction, will be great, and I will update at least one phone, and see difference. I already reset home router, I reset network setup on phones, wipe cache on both phones, still problems, and even when I am not at home, wifi playing, as I can setup wifi hotspot and I am away from any wifi. Many thanks..
Sorry that was my bad, I forgot I was looking at my m9, not my U11. You are up to date.
My post has been edited. Follow that.
To have the same problem on both phones is very strange indeed. It must be network settings causing the problem unless you have an app running that monitors WiFi in some way..
I, too, have been having WiFi problems all of a sudden. I am not stock, I'm on viper with EAS kernel, but was running it all just fine for a while then without changing anything, I have the same problem.
Still looking for fix, but no luck so far, tonight I reset router just to be sure, but problem is still there, I am sure sooner or later I will find out what is behind this problem.
