(xoom 2) XOOM 2 10.1 Freezing & Reboots – A SOLUTION!

I just wanted to share with you my recent issue & solution to the XOOM 2 rebooting issue.

Now to give you an overview of my situation, I purchased the XOOM 2 10.1 UK back in January 2012.

I use it almost every single day. No surprises I was getting random screen freezing followed by reboots every single day. Most days twice!

Now I was hoping that when the update happen back around 2 months ago that it would solve this issue. It never.

In fact my freezing & reboots were happening more frequent.
Basically within 5-10 mins of using the Xoom2 it would reboot.
Some days I just wished I could throw the dam thing through the wall.

I rooted using Dan’s method. The only method. & tried various ways to solve the issue.
NOTHING worked.
In fact, I was convinced that my rooting & installing things that should not be there was making the reboots worse.

So I cleaned up my Xoom 2, went into recovery, wiped cache & cleaned data & rebooted.

This still did not work.

Then I tried task managers, cache cleaners & even paid for that system panel app that logs all apps & usage.
Nothing worked; I was still getting the reboots. Everyday.

So after looking over many Xoom 2 forums & with many issues and complaints about this issue, I was close to selling & getting an iPad.

I was convinced it was hardware.

Then I tried this way:

1. I rooted.
2. I installed ADW Launcher & made default.
3. I installed SetCPU
4. I installed Titanium Backup
5. I froze the stock ‘launcher’ – (whatever you do – do not un-install any app, you CANNOT update Xoom if you do)
6. I changed CPU from ‘hotplugmoto’ to ‘performance’ 1200min 1200max
(I know you might think this uses lots of battery but I found not)
7. Set up setCPU profile for ‘screen off’ I use ‘on demand / 300 to 600’
Battery over night on this setting did not go down by 1%
8. Rebooted.

After 4 days of constant use & trying so hard to get the Xoom to freeze & reboot – I can’t.
This method works.

I have surfed using ‘Firefox’ while using ‘Currents’ while using ‘Google+’ while downloading files and steaming music via ‘Google Music’. I have open every single app & been quickly switching between them all trying to over load the system.

Nothing will freeze or reboot my XOOM 2.

What I can get from this is that the Xoom 2 works perfectly.
With the high CPU set, it is so fluid and lag free. It works almost perfectly now. It also means the hardware is absolutely fine.
Maybe with newer firmware updates in the future this will be sorted naturally.
I makes me think something with the high CPU means a bug in the processing won’t make the Xoom freeze & reboot.

Until then this method works for me and I can’t see why it won’t work for you.
If you are having this issue I hope this helps.

I messaged you on the Motorola Forums, but I think they may take it down since they don't like talks about rooting.


But thanks for posting this, I will give it a shot.


When you changed to performance 1200 min/1200 max - I'm guessing you also checked set on boot? right?

Yes i ticked set on boot. Make sure you have a screen off profile otherwise it will be running at max all the time.

Hope it works for you.

Hi,

I froze some bloat before and uninstalled flash 10.3 cause flash streaming online videos didn't work 4 me (neither 10,3 or 11,x), then installed flash 10.2 and all starts to work ok but still 2 or 3 reboots for week.
Also seems that "memory booster" app helps when some apps starts to freeze and u can finish em and free some mem.

So now i'm trying setcpu and then i will do launcher trick ;)

Thx a lot!

Hi

I switched launcher on personal preference but to be fair I have had no freezes now for 5 days

So I'm not messing now if it ain't broke.

The reason is I did this is I read 1 post on another forum that someone changed launcher &, this helped him.

So wether launcher or high cpu I'm not bothered

To finally have a working tablet is such a huge relief!

Thank Vanpeebles,

I did everything you said and now hoping for the best!


Either way, I'm loving ADWLauncher Ex..... sooo fast and snappy!

Thanks my Xoom 2 is running great again! :)

Also add this warning. Do NOT remove the Launcher2 app if you do then your Xoom 2 will never boot again and the is no current way to fix this because of the locked bootloader. :)

That's my question, why do you even need to freeze the stock launcher if you've set adwlauncher as the default.. like what's the point of that step of freezing the stock launcher, it shouldn't impact performance.

No he is right, because the stock launcher takes a big bite out of your RAM around 100MB. And even if you do have another launcher running that stock launcher always seems to be in the background on my tablet. :)

Yeah but won't freezing the launcher (or changing its name to launcher2.apk.bak) cause problems if your tablet faces a failure and the adwlauncher crashes?


EDIT: I guess titanium backup unfreezes apps if you do a wipe so the best option is to freeze the stock launcher (NOT uninstall it and NOT rename it)

Over 1 week now and not 1 reboot.

I can't answer these questions on the launcher?

All I know is this works for me, I have had not 1 freeze or reboot, so the stock launcher can stay frozen.
(it may have absolutely nothing to do with it, but I really don't care)

Hi after several days over GO Laucher EX (or HD "Tablet version but less customizable") with Setcpu 1200 1200 performance and etc....

only 1 reboot when several web pages were opened on stock browser with flash videos etc.
I've noticed that now when apps stops to work it goes back to home instead of reboot except that time.
Almost no free ram and that's seems to be the clue..Stock launcher doesn´t free enought memory

And battery drains suddenly stopped.

Super happy man ;). More fluid launcher, more customizable, and also wifi starts to work better when comes back from sleeping

Thanks for not to give up!

Have to say... this solution seems to be working very well. I'm running set CPU in conjunction with auto memory manager set to "aggressive" and AdwLauncher Ex!

Using many apps that in the past would give me reboots, but now they are working flawlessly.

Thank you very much for this awesome contribution!

I'm Xoom 1 user and also having annoying reboots you described here. Most of all it happens when watching movies or iptv in player.
But isn't setting cpu frequency to 1200min will force cpu run at 1200 not less all the time? It probably may overheat the cpu and sounds dangerous. :eek:

When its in use yes, but you also set a second profile to turn down the cpu to a lower value when the screen turns off so you don't drain battery and cause overheating!


So far - I'm running this method without any problems, no noticeable battery drain or extra heat in anyway!

I'm currently running on stock kernel without ability to scale over 1000. Tried to set to performance governor only, but failed and got regular reboot during usage. Will try your method.
Seems to be it's operating system problem. Don't understand why motorola still didn't resolved it, including that fact that problem also present in first Xoom model. :mad:

Worked a bit around with your solutions and stabled on the following:

  • Stock launcher frozen;
  • SetCPU profiles:
    1. Screen ON/unlocked: Governor OnDemand (1200-800) with Noop Scheduler
    2. Screen OFF: Governor standard hotplug (800-300) with noop scheduler

It looks like moto_hotplug governor doesn't work quite well but I also noticed some glitches on systemui.apk. Whenever you turn your screen on and unlock doesn't show smooth you must turn off screen and try again... if you unlock with a laggy unlocker the whole system will be a mess.

With those setting I'm not having reboots, just some lags here and there; battey, however, lasts much less due to ondemand governor.
