Need some help with rooting/updating (UK wifi)

Hello,
I'm not new to rooting, but the Xoom scene is very confusing at the moment and I just need somebody to direct me to the proper guides and confirm that I'm not going to blow up my Xoom and/or tear a hole in the space time continuum.
Situation is this: I have a stock UK wifi Xoom and want to get to Android 3.1. I'm not willing to wait until 2013 for Motorola to pull the finger out and give their European customers an update.
SO
Obviously I need to root and apply the update manually.
I'm willing to risk the one-click method (I've seen other UK Xoomers have had some success with it).
Where do I go from there? One-click method says it will install tiamat kernel... but I've read that this isn't compatible with 3.1. So is there a guide that will take me from tiamat to 3.1? Do the update methods replace that kernel anyway? Am I going to go completely f*cking crazy if I have to trawl through another 50+ page thread full of conflicting info? (Yes.)
Any help would be appreciated.
Thanks.

Im not an expert at any of this, just a regular user but heres the guide i followed to get my uk wifi xoom updated. Http://forum.xda-developers.com/showthread.php?t=1074609
However you need to be aware that this software is the us version and you will ony have access to American English. You will lose all the European languages.
Also you need to be aware that if you unlock your bootloader with "fastboot oem unlock" you can not relock it. Trying will brick your zoom. (Currently)
If you could do a full system dump of your xoom as is with the UK wifi software that would be awesome as currently nobody has uploaded one and im trying to get back to stock and Motorola have only posted the us images

Thanks. I don't mind losing the languages. I'm using SwiftKey so I can just download any language modules I need.
I would certainly be willing to upload that if I had the faintest idea of how to do it! If I can get a step by step guide I can give it a go... and as long as I know I'm not also uploading my personal details and authorisation tokens etc along with the software!
Any particular reason you're going back to stock? Bugs or anything?
Edit: the canadian system image has the full set of languages if that's what you're looking for...

Sorry, didn't have time to wait for a reply, going out in a while.
I did a factory reset and then an adb pull so I've got all the system files etc on my PC. Not quite sure what to do with them, though. They're not in .img format, just in a folder?
Anyway, now rooted and running 3.1. Cheers for the link above.

Is anyone else getting a 4.0 OTA notification?

This may be a known issue but my wife's (non-rooted, completely stock) A500 has been getting a 4.0 OTA notification since yesterday. It says it's invalid, after downloading it, so I ASSUME it's not actually for this device but is that the case? If it is for the A500, do I need to do a factory reset to get it to update?
Thanks, and Merry Christmas!

What version is it running currently? 7.014.02
I have not seen anything since the 7.014.01/02 releases a few days back.
It would be nice to see Acer taking the lead on releases but I will believe it when it happens. The. 02 release did have a new to me update screen when it installed....
Wowsher

I think I know what one of the issues is- This must have been some really old stock (bestbuy.com) because it's running 3.0.1 and the kernal version is 26.36.3-00001-g9b3ce2b. Is it possible that it's somehow "skipping" the OTA updates in the correct order (or maybe they aren't available OTA anymore?) and thus giving me the "invalid" message?

yep would not surprise me at all... you should be able to download from a thread in the rom area a thread by vache has links to almost all of them.
You should probably change the thread title if you can.
Wowsher

There have been others with similar issues.Seems like acer did not and is not pushing the updates to some devices.
I would first call acer if you. Not likely to help but would atleast let them know they have issue.
For a right now fix.
Get iconiaroot. Root tablet.
Get acer recovery installer. Install custom recovery.
Look on forums for a stock 3.1 or 3.2 rom.
You can get a ore rooted rom if you wish but would kill all updates in future.
There are lots of information in the dev forums on step by step instructions and downloads.
Be careful fallow instructions.
Good luck.

The 4.0.xxxx update, is an update for UI. It should come in 2 notifications for stock tablets.
The first, is a preparatory update. The second, is the actual update.
Note, if you have a rooted tab, as some people can tell, it is not advisable to take any OTA update from acer.
In the forum, if you want to take the update, there is a thread which has rooted versions of these updates.

[INFO]-Root-Unroot-Restore-Lessons learned

I originally posted this on the Asus TransformerForums. Still no update from .13

Root-Unroot-Restore-Lessons learned
Hello all. I've had my TF now since September or October and enjoying every minute of it. Bought mine in Japan so it was HTKXX.JP_epad-version B70 model. Like so many of us the first thing I wanted to do was root it and install custom ROMs. Being the B70like many I had to wait until Razorclaw was released but as soon as it was I was ready to root.
Let me say I'm not well versed in rooting, intalling, and troubleshooting Android devices...and like many the tablets are new to me. So, to help me figure it out I search and read the forums, re-read, and search again. Notice I said "search the forms", that is very important before posting questions as most of our questions have already been asked and answered. That being said, its ok to post a question, I've found the admins, mods, and other people with experience, problems, and solutions all willing to help. Don't forget, these people do this freely so always respect them even if you dont like the answers or advice they give you. Many of us would have some very shiny paper weights if not for the help from the many on here.
Now..to continue my little adventure. And root I did, Prime! 2.1.0, Revolver, Revolutions HD, and back to Prime! when I had questions I turned to the forums, and sometimes was even able to give a little advice myself. With ICS on the horizion and the latest OTA I thought I should look at unrooting and returning my device back to stock. So, again I turned to the forum for information. Because my TF was the JP model I was concerned there may be something with the build that would prevent this or I wouldnt be able to get the right firmware. You see...there isnt a lot of information related to JP models on the forum. I didnt realize they are all "pretty much the same".
Either way, I eventually posted a question and right away was helped with information or unrooting and reflashing back to stock. All the information however was to restore the US model. After some discussions with one of the RS guys I decided what the heck...gonna try it anyway. (the tinker/challenger in me)
Very good instructions for everything I wanted to do were there. If you think I'm joking, check the signature of RS Team Lead Frederuco. It's all there.
End result my TF was unrooted and now have ver 3.2.1 US.epad-8.6.5.13-20110925 kernel ver [email protected]#1. hmmm...I was worried because everyone was talking about ver.19 and .21...am I in trouble? I've tried various things to get caught up even with a version that I could possibly re-root. Oh boy....even trying to go back and get the JP update from ASUS didnt work, my device is now a US.epad device. My thoughts were...well, at least its still working.
Then I decided to do a bit more investigation, so i went to one of the local computer stores and checked the build and kernel version. I was suprised to see that the only difference in what I now have and what's in the stores is the JP & US. So, maybe what I'm waiting for hasnt gotten to Japan yet...or the ones in the store just haven't been updated. (more likely the case)
Either way, the point and advice here is this. if you decide to unroot and restore I dont recommend to the weak hearted to use a SKU other than what came on your device. It worked yes but not sure where I'm going from here. For me, it doesnt matter as I can always manually update when the versions are on the ASUS site. Worse case, I would have just bought another device and ....yep probably rooted it right away
We all know the risks we take when rooting, tinkering, etc. If you take the plunge, search, read, asks. And respect the people helping.
I hope this in someway helps someone
Update:
I've been able to get my TF from US.epad-8.6.5.13-20110925 to WW_epad-8.6.6.19-20111101 If nothing else I can at least root again. Will probably wait to see if I am actually getting OTA or not. The steps followed can be found in dev post "possible fix for lost root with 8.6.5.21" Sorry, I cant post links yet...
Note that I've changed the SKU on my device from JP to US to WW. So far I haven't seen any problems because of this. (still, if you aren't sure I recommend you dont)

[Q] OTA update not working

Unrooted my tab and trying to get it back to the latest official version, but I'm having loads of trouble. Please help. Thanks!
My model number is A500, Android version is 3.0.1, kernel version is 2.6.36.3-00001-g44a8bac and build number is Acer_A500_1.145.01_COM_GEN2
This is the tab that best buy had on sale a few weeks/months on sale. Only 8GB of on board storage.
I have found threads with official updates, but don't know which is safe to install. They are all the same version but have different build numbers so I don't know which build number corresponds with my tab
I think I know the answer to this already, but can I jump from 3.0.1 to 3.2.1?
Anyways please help. I do appreciate it.
Thanks!
EDIT: 99 views and no replys? Do you guys not know the answer or are just being jerky? This is seriously my first post let alone question on the acer threads. I usually get things pretty easily, but I am having trouble on this one so it's not like I'm being lazy or asking a stupid question. Can someone help either by providing some answers or let me they don't know how to fix this??
Thanks
EDIT 2: Close mods

Not sure if you're still with us -
interested in knowing why you have not rec'd any OTA before now -unless you've been rooted from the start like i was when i got mine!!!
you also have to be stock, as in factory stock! the update checks a whole lotta stuff before it will install . If the system doesnt stack up the update will fail. So if you have deleted or frozen bloatware apps they will need to be restored, along with modded build props etc. factory data reset and full wipe fixes that problem, but Most people want to keep their data if they can and isn't an option. The update itself should leave everything in place. Mine did.
u need a Gen_2 build. I'm not familiar with your build number or upgrade path for 1.145, but you should receive an OTA for 3.1, 3.2 and the latest 2 for 3.2.1.
if u just wanna install one of the updated custom stock roms with root or cwm, you should be fine with any build and yes you can go straight to 3.2.1 from 3.0.1, but no OTA with these roms

This is a known issue and too many reasons to list. But, basically you are not 100% or it thinks that (checksums different) etc.
So, just flash directly to 3.2.1 GEN2

Mods please close. I was able to fix the issue
I was rooted and had to flash to 3.0.1 or 3.1 before unrooting with the iconia apk. Then I used the acer recovery tool to flash stock recovery. But after flashing stock recovery and unrooting I couldn't get any OTA updates. I re-read some the posts and manually updated to 3.2 after decrypting the zip. After updating I checked for new OTA updates and sure enough found both. Now I'm back to stock 3.2.1. Patiently waiting for ICS

Glad you got it working.

[GUIDE]/[RESOURCE LINKS] For updating X 1st Gen LP 5.1.

This thread might help you with the resource, links and few information about upgrading to Lollipop 5.1 when the official OTA arrives.
BEFORE WE BEING, LETS SUM UP WITH THE THINGS WE KNOW TILL NOW.​
After agers, Motoroal dropped Lollipop for our Xs
First the LP 5.0.2 came out as soak test
Finally LP 5.1 OTA hit the brazillian markets a couple of days back
We can expect to hit all other markets in couple to weeks.
Now things we need to know for successfully installing the OTAs when it finally arrives in our regions​
** I'm expecting all of you(reading this) are rooted with locked or unlocked bootloader **
*If you are not rooted, you are set, stop reading and count clocks before it hits your region*​
Now whether you are have locked or unlocked bootloader, I'm guessing you have Custom Recovery installed (TWRP,CWM, etc).
and might or might not be running a Custom ROM.​
For both the cases, you can never successfully install OTA when it arrives cause it has a pre validation check, which will fail if it recognizes anything other than stock is installed.
For more info :
http://forum.xda-developers.com/showpost.php?p=59524348&postcount=324
AND NEVER TRY TO DOWNGRADE CAUSE IT WILL BRICK YOUR DEVICE OR SET IT UP FOR BRICKING LATER (IF IT DOESN'T BRICK, WHEN TRY TO INSTALL OTA IT SURELY WILL)
​
More Info
( http://forum.xda-developers.com/moto-x/general/info-warning-risks-downgrading-impacts-t3058202 )
So, it narrows down to a particular question " What should be done if we want to install the OTA when it arrives.? "
This is what you need to do :
Flash Stock ROM (if you are using Custom ROM) and Stock Recovery and then download the OTA and give it go....
** its good if you install both Stock ROM & Recovery, cause you might knowing or unknowingly tampered your system partition by installing/experimenting with several modules and framworks (xposed for eg) ** ​
which by the way raises the following follow up question :
Q : Where to find Stock ROM ZIP file and how to install it.?
A : For this, first you need to know which Model of Moto X are you using and download the same and the flash it.
For getting to know and downloading the your region specific ROM zip file please vist ;
http://forum.xda-developers.com/moto-x/general/info-tip-web-sites-official-leaked-roms-t2923347
and for the flashing guide :
http://forum.xda-developers.com/moto-x/general/guide-moto-x-return-to-100-stock-using-t2446515
Please go through and read carefully to both the threads, and you will find yourself happy with LP 5.1 when it finally comes.
I have no hands in making the links mentioned, all this is done by spending hours of research time by these people.. *Say Thanks to Them*.. I just accumulated the data to provided a one thread solution.

I haven't posted this cause, its not the official OTA installation thing, its just restoring a TWRP backup. which in case has many bugs (eg speaker phone, Network selection etc.)
I also admit that there is no contribution from me, in creation of the links I've posted, I just accumulated the data for myself, in thought that, when the OTA hits my region, this would help me going back to stock.
I made this thread thinking that, if in some way I could also help others who are looking for a solution for this.

The tips posted in -> http://forum.xda-developers.com/moto-x/general/faq-kit-kat-how-to-prepare-carriers-t2536735 still apply for Lollipop...
