[Q] How to downgrad to 3.1 - Thinkpad Tablet General

Hello everyone,
I have search the forums for a solution and found no results. I currently have a Lenovo Thinkpad 1 with ice cream sandwich. Is there a way to flash back to honeycomb? I can't seem to find any stock roms or how to for downgrading.

Lenovo don't release any full rom dump.
So il you don't have done a backup with CWR, it's not possible to downgrade.
You must ask for someone to share his backup (I'm also in this case...)

Why would you want to downgrade?

I have a similar need. I have a 16GB US TPT, it's running the CM9 Alpha, and I can't seem to get it back to stock. I have an nandroid backup, but CWM is acting too flaky to restore anything. If I can get the backup restored, and it's really 3.1, I'd be glad to share.

The reason for downgrading is because an app we use was made for honeycomb and there is currently no update to ICS for it. If we have a tablet with 3.1, how can I make a backup of that to re-install on the tablets with ICS?

I got my hands on a honeycomb tablet. What is the method to install root + cwm? I already tried a couple but all of them are getting the "read only" error.

To Root or Not to Root; That is the Question

I rooted my VM Cruz Reader to get app2sd working. So I have a tiny bit of experience rooting a device. I'm still a nooby to Android, and wondering if I should root my A500 (I'd really like to get rid of those goofy "rooms" or whatever they are that Acer added). What's giving me pause is the OTAs. I read recently that HC 3.2 will soon be out, and later this year Ice Cream Sandwich will be out. Will rooting my A500 impede these updates? You can imagine my joy at using the A500 after using a Cruz Reader. Consequently I'm really worried about bricking it. There's a lot of difference between the value of a Cruz Reader and an A500.

Depending on which version of Droid you're using, you can use either "Gingerbreak", or " Iconia Root" to root your device. Both are easy to use, and you can unroot just as easily and receive OTAs. Before you ask, use the search function on this forum for both the aforementioned programs.
Thanks. I've already read about the roots, and I think Iconia Root will work for me. So if I'm understanding you, you remove the root for the OTA, then re-root? That's it?

what it seems like you're missing is tha tthe devs here will have the OTA releases as well and implement the new features/whatever into their roms....if it's anything like any other devices i've had, they will have the rlses before you would get it OTA. No reason I can think of not to root. Just by not getting the OTAs you won't be missing out if you stay current with whatever flavor rom you prefer

I'm still up in the air with the whole rooting thing for a tablet, don't get me wrong I'm not a noob at it as I have a rooted, rommed, themed DroidX, but I justndont feel the need for it on my tablet. And of course I'd have to go back reread everything on how to for this tab which I did for my dx and takes alot of time. Just curious is there a fail safe for tabs for instance my DX has a SBF fail all bricked all emergence fix, is there such a method for my iconia?

Rooting won't block OTA's. However, it allows you to do plenty of things that WILL block OTA's.

Root Keeper app

There is an app in the market called Voodoo RootKeeper. It's suppose to backup your super user permission. Meaning you can unroot with a click and then re-root with a click. Which would work great with OTA downloads without losing root. Has anyone tried this with their Xoom?

Reading it more closely, it looks like it wouldn't help much if you have a custom Rom or kernel, just if you're rooted stock. Then you could use it to take an OTA update and then reroot. That would be cool.

It also would be a viable tool to use for apps that won't except root. Such as movies in the Market. You could switch to unroot download movies then switch back to root when you're done.

I'll try it tomorrow before I flash the new Eos nightly. Actually, there's a chance it might not work with ICS I guess. I'll try it anyway.

Doesn't seem to work on ICS. Installs OK but doesn't show device as rooted. Also there's no unroot option so can't test properly. Similar feedback on the Market for Galaxy Nexus owners.

Thanks for sticking your neck out! Too bad it didn't work.

[GUIDE] How to prepare for ICS upgrade for root users

Look at the following description and choose the right one.
(1) Flash back to stock rom and stock recovery via easy unroot.
(2) Re-root via nachoroot
(3) Install OTA rootkeeper.
(4) Wait for ICS. Call in sick everyday if you have to. Keep mashing the check for update button.
That seems like a lot of pain when the devs are certain to adopt the ICS Asus rom as base to their custom roms.

Because if you rooted via nvflash then you won't be able to do an OTA update even if you have ota rootkeeper. Trust me, I've already tried it all.

Well sure. That might be. But that will take time.
Some people want the ICS update the very second it is out. Reverting to stock allows them to get it the second it is out without waiting for ROM developers to update and retweak their ROMs for a new major Android-version, a process which most likely will take some time.
Besides. I like to know how the stock experience is before going for something different. If stock is good enough, I see no reason to rely on custom ROMs.

It should take only an hour or two to push out a rooted build. Will probably actually get it before being the ota build.

OTA update will not work if you're on a custom ROM or have CWM recovery.
Stock but rooted ROM is OK

I've heard CWM shouldn't prevent an OTA update from going through. From someone in this forum. Referring personal experience.
That said, I agree about custom firmwares.

The OTA update will not automatically install if CWM is installed like it is the case on a completely stock TF.
Therefore some people adjust the OTA update (remove recovery and add root) and publish this so you can install this with CWM. See developer forum.
The original OTA update also include recovery update (where CWM is installed) and remove root. You can use OTA rootkeeper to avoid loosing root.
Summary:
- root with stock rom and stock recovery will allow OTA update from Asus but you loose root; use OTA rootkeeper to avoid loosing root
- root with stock rom and CWM recovery will not allow OTA update from Asus; use adjusted OTA update and install with CWM (keeps root and CWM)
- custom rom, then no OTA update possible; just wait for update of developer custom rom

Well, stock has gone a long way from back in May. Back then, I went with custom roms because they were more stable and smoother to work with. Recently, I flashed back to stock and have been using it daily. Could not tell the difference between stock and custom rom anymore. Asus, or google, has done a good job at stabilizing and improving the original stock rom.
When ICS comes out, I will at first use stock. Then I will try out custom ICS roms. I'll evaluate them on a regular day to day usage. I don't care much for all the tests that people do. I'm a realistic guy. I believe in reality.

Sorry that just made me laugh. A stock rom being good enough would mean no need for custom roms and so far, not one single device has had one. Not even vanilla rom's from Google themselves.

Unfortunately I don't think updating CWM will help, I suggest you try to install TWRP, flash the ROM, then re-install CWM if CWM is your favorite (or you have CWM backups) but yeah, TWRP is your best bet right now.

If you want to update to 4.3 get the images for your device from here https://developers.google.com/android/nexus/images, uncompress and run the flash all scrip inside. Be sure to backup your d data as you will lose all of it (including internal sd).
