OTA2 -- A Few Stupid Questions

2012-02-06, 1:59 AM

A few questions about Over-The-Air  updates:

 

1. If you do not own a 3G-capable TPT:

 

         a.   How can Lenovo push an update down to your TPT?

 

         b.   How can your TPT ever "know" that an update is available? Or does it silently check a website for update availability every time your TPT connects to the internet? Any idea where it chekcs

 

2. When OTA1 was released, were users given the option to decline it? (I don't know, because I bought my TPT 1838-25U on Ebay and don't know if it came with .75 on it or it updated after I bought it). 

 

3. What is the mechanism behind Rootkeeper (e.g. renaming some file; making some file read-only) that makes (at least on other systems) a device immune to an OTA installation without the owner's consent? Presumeably, whatever Rootkeeper does, you could do yourself manually, although an automated approach is always easier. 

 

4. Do we have any good reason to believe that whatever voodoo that Rootkeeper does will actually protect us from an involuntarily-installed OTA2? (Not that there's any harm in installing Rootkeeper, even if it doesn't work). I also own a Nook Color Tablet. I believe that lots of owners of NCTs lost root, even with Rootkeeper installed, as Barnes & Noble launched a campaign to eradicate root that Bashar al-Assad would be proud of. I'm not knocking Rootkeeper. I'm just curious what a manufacturer like Lenovo or Barnes & Noble can do to force an update whether you like it or not. Likewise, I wonder what an owner (or Rootkeeper) can do to protect his/her device from involutary updates.

Go to: settings> about tablet> system updates> check for updates. if there is an update available, it will tell you and give you the option of downloading it or not. it isn't forced on you, or at least the last one wasn't.

When ota1 change out, I didn't know about it until I saw posts about it on the boards. It didn't download it automatically.

I don't know anything about root keeper.

Is OTA 2.x US available? I still have build A310_02_0037_0075_US and receive the "Your system is up to date" message after checking for system updates. How do I install the latest US build?

you have to download "voodoo OTA rootkeeper" and check the box for temporarily disabling root. then install ota2. then reinstall the SuperUser program (which will disappear after OTA2 is installed). then re-enable root using voodoo.

at least that worked for me.

Don't forget to make a backup with Rootkeeper before you do anything.

Re: OTA2 -- A Few Stupid Questions

I am still a bit confused about the OTA, so please forgive me if these are silly questions.

 

I am still on build 65, and never got a notification about an OTA.  Every time I selected "check for system updates," I got a brief "downloading" message but nothing seemed to happen.

 

So, after doing some reading in here, I checked my downloads folder and there it was, 60-something MB zip file and and an XML file as well.

 

A couple of questions:

 

(a) Do I just unzip that file and the update will install automaticaly?

 

(b) Does the tablet have to be plugged in for the update process?

 

(c) I know that there have been several updates since 65, so do I need to install the one I have in the zip file (I assume 75) first and then the others?  Or can I go straight to the latest one (available at the Lenovo site)?

 

(d) Anything else I must consider to avoid any updating problems?

 

Thank you for your help and apologies if these questions have been answered a million times.

I had a similar problem with my TPT not detecting the newest OTA.  I followed the instructions for manually installing the update at:

 

http://forums.lenovo.com/t5/ThinkPad-slate-tablets/Instructions-How-to-manually-install-updates-and-fix-stucked/m-p/579867#M5288

 

I don't know why my TPT didn't detect/download/install the update using the "Check for updates," but this manual process did the trick and was easy to follow.

I forgot to point out that you must have your TPT connected to the stock USB Power Cord/Adapter or the Dock during the update process as indicated in several other previous posts.

Thank you, so the update zip file can only be executed in recovery mode?  And my second question is, when they say save update zip file to sd card, do they mean external or internal sd card?  Thank you again.
