4G Xoom has major connectivity problem. Anyone have latest Stock Kernel? - Xoom General

I got my Xoom back last week and have been trying all weekend to figure out this problem.
If i set it down for 20 minutes and come back, it shows no network connection. Airplane mode cycle doesnt fix it, and i cant toggle wifi... it just sticks on turning on/off. Only way to get back to 3g/4g is to reboot.
I rooted when i first got it back, then got the new OTA to "D" and re-rooted. Everything works great except for this sleep bug.
HOWEVER... First thing I did after i rooted when getting it back was to load the Tachi OC GPU Kernel. It has been on there the whole time, and it didnt get overwritten by the OTA. Im wondering if that could be part of the problem, but i cant find the latest stock kernel that should be on the device to test. I wish i had an SBF of the latest OS.
Anyone else experiencing any of this?

That kernel is probly causing it. I would try and put a new kernel on and see what happens. These things have power consumption issues now.

This is how I rooted from stock. Mine and my wife's. No issues with connections so far.

I followed that too. Root is on and working.
I opened box from moto, powered on and activated SIM. Then rebooted and pushed the recovery via fastboot. Then rooted using that method and applied the Tachi OC kernel.
You have done all my exact steps (What Ghz do you OC too btw?) and yours will sit on the desk for untouched for say an hour, and when you come back you are still connected to 4G? if so, then i have a bunk new 4G radio.

I don't. But I don't think I'm running the tachi oc.

Do you have setcpu or a OC kernal by any chance?
I am having this happen also... I have had to remove my battery three times today to reboot the phone.
I have set CPU installed, is that a bad idea?
I'm rooted with just the stock OS, no mods at all and my phone will randomly reboot every two or three days.

No, I'm rooted with straight stock. No set CPU or anything of that nature. But like I said even then ill get complete freezes and then a reboot. Or occasionally ill attempt to open an app and the phone will reboot!!

did you wipe your SD cards when you flashed the new rom? I don't have this behavior but I did have FC's and such because of some files on the SD. I have NONE of this behavior. Something is wrong for you, nothing is wrong with JI2 and freezing/rebooting.

I used to have this problem all the time too whenever I tried to use the gps, but since I've applied the leaked update that problem has gone away. But it seems like you're experiencing the issue at more random times. Have you noticed any particular pattern? For example, whenever you try to play music in the background and read a website at the same time.

Yup mine is bone stock not Rooted and it will lock up just siting there GPS, wireless and Bluetooth off in a very good signal area.
Same here on both roms. I thought the lag fix was causing the freeze. But now im stock jit2 and root.
Had the same with gps and maps with old firmware.

I haven't had this issue happen since I applied the flashable gps fix. Maybe it was an issue with an app that wanted to use GPS running in the background?
This has happened to me several times while booting gps and only recently started happening while playing pandora, but not as frequent as while using the gps...not rooted

Mine has only frozen up once and it was at the end of a call screen turned off. I hit power and went to go unlock and it turned off again.. Would not turn back on but I know the phone was still on since I had apmobile enabled and it was still transmitting wifi connection. Oh I was using eugene's FrankenTwiz (underclocked to 400mhz)when it happened but same thing happened to my girlfriend and she had hybrid r3. Other than phone runs fine.
Ive had some odd reboots where I dont get a shutdown or boot animation or sounds, just freezes, goes black, keys light up, searching for signal boot process. Yesterday in maps trying to troubleshoot my gps. Stock rom,rooted, Ryan's lagfix.
Vibrant vibrating nicely now,Kthx!
Have the phone replaced. I had a phone that would randomly freeze and/or reboot. Nothing I did would fix it.
I talked to a T-mobile worker who had the same issue with one of the early demo-phones Samsung loaned to him. They just replaced his without every saying what the problem was.
I've been having this happen a lot lately myself, it happened to me before on stock ROM due to SetCPU, but now on the leaked ROM. I did not clean the SD card (internal or external), so will give that a shot when I have some time to copy files on/off the SD cards (one reason to dislike the internal SD is that I have to mount it to copy the files, ergh).

Lose 3G and have to reboot

Anyone ever have this problem? Ideas to fix it?
What rom are you running? If its a i9k 2.2.1 build you need the signal reboot fix found in the vibrant development section.

I think the problem exists for KB1 based builds as well. Had the issue with Bionix 1.31, Trigger and Axura. Went back to Nero v5 and problem solved. Also, the wifi sleeps even when the option for never sleep is checked. I wonder if it's hardware specific and only affects some phones.
Sent from my frozen yogurt powered Vibrant
To clarify my previous post: I lost 3g and had to manually reboot to get it back. It didn't reboot on its own like the i9000 builds. I ran 3 different roms from 3 different devs and they all had similar issues. The only common denominator was they were KB1 based. KB1 roms also seem to have RIL issues (very infrequent). At least that was my experience.

Data dropping happened to me a lot in the JK2 modem (had toggle flight mode on and off), but it has never happened to me since (JK6 and onwards)
Are you guys on t mobile? You might want to upgrade your sim card, i just upgraded yesterday and now my connection is more stable.

If data is just dropping and not soft booting, try flashing a new modem.

I dont have this problem but do all the ROMS now say "H" instead of 3G? The weird things is, I still 3g pop back up there intermitently for a second or two here and there...from what I gather, H is the same thing, but if that's so, then why do I still see 3g pop back up there sometimes?
I'm on KB1 and I hate this ****.

I had this problem on Trigger 2.7.1/overstock couldn't reestablish data through airplane or toggling data type. In since flashing 2.7.2 havent had it at all. Fingers crossed. No reboots either. Same kb1 modem.
Don't blame me, blame my keyboard's autocorrection algorithm.
Im going through something similar right now. Running Axura 2.3.1.0 with KB1 modem currently, was on CM7 with KA7 prior and had same issue. I have 0 3G, doing a speed test on 2G i get between 68 and 85kbps download speed, and when on 3G i get between 46 and 60kbps, so actually my 3G is basically dead. Went and got a 3G sim card from t-mobile, called them about 26 times and had them reset my network, filed a trouble ticket and still no dice... not sure whats going on. I was throttled and my cycle restarted on the 21st, its now the 24th and still seems like im throttled but im not, its actually a dead 3G, not sure why... anyone know what i can do to fix this? Is it a bad phone now? T-Mobile doesnt seem to have a clue, nor will they help me out... dunno, tried everything and now im just stuck with no speed... blows!!!

Has anyone ever had this data problem?

Alright this is just stupid. So I wake up this morning using facebook and browsing xda over 3g. I pop up power menu and turn off data, and leave phone for 30mins. I come back, turn on 3g and nothing. I've went to network settingsand fiddled with all the options there; 4G, txting, calling, and wifi work. I also had the "error: 67."
Only things I've tried is cwm wipin and flashing. I currently am away from home so can't just odin =/

Maybe try switching modems? Sfr doesn't include a kernel so try changing to a different kernel also, some of the newer kernels and roms have the modem flash in the install.
Also j would call sprint and ask if there has been any changes to ur data or hotspots plan, they should be of some help in that end. I'm kinda curious as to how that would happen tho.

This happened to my wife's phone went into see what modem I put in and it was gone there as nothing but characters re flashed modem all set.
I get this all the damn time. Especially around my area. What works for me is re-entering the MSL & resetting it to default. It reactivates the device & you'll get your data back!
When I called Sprint about this, they told me that it was because the phone "jumped" to a different tower that wasn't so close. Hope that helps!

Your bill is paid, right? I thought I had a problem like that one time but turns out my payment wasn't taken out when it should have.
But since you're getting an error it has to be something else.
I believe error 67 refers to wrong vision username/password. Have you tried something simple such as Update Profile? Worse comes to worst you can always do an rtn reset...
edit: CWM doesnt write to those areas... Neither does Odin.

[Q] can't connect to WiFi running newest liquid smooth rom

As I put in the topic, I'm running the newest liquid smooth build on my N10. Everything is running really great on it, but I can't connect to WiFi at all? Sorry for posting this here but I'm a noob and can't post in the dev forums yet. Any help would be greatly appreciated considering my tablet is useless without WiFi!

Some wifi problems are inherent to 4.2. But if wifi doesn't turn on immediately after flashing any rom, usually a reboot cures it. Before rebooting tho, try cycling Airplane mode on/off.

I've already tried rebooting several times. I even booted into recovery and wiped everything again and reflashed the Rom. Still no WiFi? I've never had a problem with it on stock or cm10.1
Sent from my HTC One XL using xda app-developers app
I never had wifi issues with my N10 until I decided to give Liquid's newest build a try. I tried all the tricks - reboots, toggling airplane mode, even started from scratch and reflashed the entire ROM but had no luck. Sometimes it would connect for a moment, but then would immediately disconnect. As soon as I returned to my latest backup (Steve Spear's AOKP pub builds), and even since trying other ROMs I've had no wifi issues. I'm saying with 100% certainty there's a problem with Liquid's ROM, but it sure seems that way to me.
Maybe redownload the ROM and start over (perhaps something got messed up while downloading). That's the one thing I never tried as I got tired of monkeying around with it.

OTA 4.3 - Bad WiFi

My Nexus 7 was becoming very unresponsive and pissing me off. Was on older JB version and Paranoid Android. I flashed back to stock/wipe all and then allowed 4.3 OTA update, rerooted. Now my Wifi is EXTREMELY slow. Buddy and I at work put my N7 side by side with his iPad on the same wireless at work and his was flying through sites, with mine timing out left and right.
Any ideas why the radios are so crappy now? Did I ruin something in the flashing processes?
Would love if someone had an answer for this. I have a stock N7 (2012) and have the EXACT same problem. Ever since it updated itself to 4.3 my wifi has been remarkably slow. Can't stream any video at all. I do speedtests on my S4 right next to my tablet, and the phone is 12mbps down with the tablet being about 200 kbps. It's unbearable, I can't figure out whats going on. Tried all the usual fixes with no help.
What normal fixes have you used? I'll see if they fix my issue.

The usual. Clearing caches, factory reset, reseting my router. What i ended up having to do was root it and put an android 4.2.2 rom onto it. Immediately solved my problem and I am pulling down around 12mbps now and can stream video :laugh:. I can't believe you and I are the only ones out there with this problem but maybe. I hope next update google will fix this, i like having the stock firmware on a nexus device.
Oh, ok. Thought there were some 'normal' tools/apps to try. I'm with you, hopefully something is found soon.
Quick question, what type of router do you have at home?
Try doing a clean install of 4.3
I'm not having any problems with download/upload speeds.
