[Q] Is is Possible to Downgrade from 3.2?

I read some posts about how to downgrade the transformer's firmware, but these were all pretty old and when I followed these steps they didn't work. I was wondering if it is still possible to downgrade from 3.2 to 3.1 build 8.4.4.11.
Thanks

one way would be to follow eepad unroot thread to go back to stock 8.4.4.5 and do microSD card update to stock 8.4.4.11

Which recovery do you have?
There is an update for 8.4.4.11 on the ASUS website. This is NOT the OTA udpate. This is a zipped blob that you can flash from the stock recovery. If you are rooted with CWM, I think it might flash through the staging partition.

I have the stock recovery.

I think you can download the 84411 update from the ASUS website and flash it with the stock recovery.
It is not the OTA, but a full system that will over-write your system files. I think you unzip the file and copy the whole ASUS folder to your SD card. Insert your SD card and it will recognize and prompt you for the update. To be clear, you should have something like /ASUS/Update/US_eeepad....8.4.4.11.zip on your sdcard. It will recognize it when it is inserted.
Double check this and flash at your own peril.... it might not let you downgrade, in which case, there are 2 unroot guides in the dev section.

i want to do this, is the SD card 100% needed? i dont have one right now

Sorta- the sdcard would make it easy, but I think you could extract the pieces and flash them via nvflash.
If you are rooted, you can "flash" them via adb by copying the blob onto the staging partition.

why downgrade? it not needed to root or anything, so am i missing someting?

Have you tried nvflash? That seems to be the best way, but be sure to backup data, I got titanium backup and coped the data to my sdcard
Sent from my revolver!

since few weeks ago my TF its been having problem of deep sleeping and will turn on whenever he wants or when battery has 0% but my friend TF which is stock and bought from the same place and time i did still has 3.1 8.4.4.5.2 build is just fine so i wanted to try downgrading

You might also consider reflashing the ROM you are using now. I did notice some odd SOD issues from a bad flash. I had other issues as well- the screen would dim if I tried to follow a link in an email. I forget the actual cause, but it was fixed when I reflashed the right parts back in.

sorry im kinda newb about this.... how do i know what kind of ROM im using and how do i reflash it?

There is no exact method of knowing, but you can looking in settings/about tablet and look at the kernel version and build number. Then cross reference them with this thread. You might have a custom rom, in which case it might have the name in the build number.
You might have a bad flash. You could try charging the batttery completely (overnight) and then reflashing. If you are having issues, it might be easier to flash a custom ROM such as Prime 1.9.

Be sure to back up any important data since nvflash will erase everything.

I hate me [n00b question]

So I have a I-9020A with at&t. I have rooted followed by flashing -su and roms instructions using instructions on the net. But after following that process and then going backwards (flashing stock w/ no root locking bootloader) I have realized after that I have more questions.
So first: Unlocking the Bootloader erases the phone. Unlocking the bootloader is needed to flash CWM and SU. I have read many many things about NANDROID, how is NANDROID different from CWM?
So I guess my next question is: How does one remove SU? In the process of rooting and flashing CWM and ROMs I make a backup prior to going to deep... that Backup will have SU, I have unrooted, but SU is still on the phone and I cannot seem to remove it.
Another question is: where are the data files on the phone for apps like Plants vs Zombies? I would like to move them off my phone prior to root, though I'm not sure if that is possible (is it?).
The last question is: If I wanted to muck around with ICS and the source code, is it as simple as flashing the source as explained on the google site? because they make it sound rather easy.
Thanks for any and all help,

When I power my phone off and press Vol up and power on then go to recovery I get an Android w/ a triangle with an exclamation and cant do anything at that point.
So I guess my next question is: How does one backup a stock rom (like you would using CMW) without rooting? or is there not a way and I should just except that when I root for the first time I should expect to loose everything and take off things like pics ect before hand.

Sounds like you should have read more.
When you open the bootloader (the lock) it will wipe your personal data off the phone (not SD storage). This just means you get it as if you just bought it from the store. There is no way around it but happens only once and you'll never have to do it again. Unless you lock it back
Once the bootloader is unlocked you can now flash a custom recovery such as CWM which will let you manage and back up your phone with whatever ROM you want/have.
Once recovery is on your device you also have to root the phone. For this you'll need a zip flashable file with the superuser apk and SU binary files. Flash it in recovery and you should be good to go.
The last step is to install a ROM of your choice. You can just run what the phone has and it will work fine and even take updates without a problem. However, every time you want to flash something you'll need to flash CWM again because the stock image flashes the default recovery on reboot. There is a file you can delete to prevent this from happening. I forgot the path so look around. However, I would recommend you flash a stock ROM which already comes loaded with good stuff and all other things are done for you Just stop by the development section and pick a ROM you like.
Naroid is just a backup.
Oh, and BTW, mocking around with ICS... I would leave that for later. First get your head around basic flashing/rooting stuff. Changing the source code requires knowledge of code and even phone hardware. I'm guessing it's not for you just yet

i was going to write something similar. toonhead85 you should do a bit more research and reading before you start hacking on your phone. youve hearts in the right place, but youre not quite ready just yet. at least take small steps at first

A little more clarification or nandroid backups:
Nandroid is a specific type of backup of the phone's system files. I think that includes system rom and radio. I not sure if any data is included in the backup. You should make a nandroid backup of the stock rom bbefore you flash any custom roms. If something goes wrong with a rom flash or if you want to restore to a previous stock or custom rom, you can restore from the backups you have made. You create these nandroid backups by booting into recovery and selecting the backup option (I think maybe named backup and restore). Backups are usually found on your SD card, but you can copy them to your computer to save additional copies.
If you want to also backup apps, get a good backup program from the market. Two that I have used are Titanium Backup for Root and MyBackups for Root. They can backup and restore apps and data as well as system data.

Thanks for all of the amazing replys. I do know that I am not at the point where I wanna muck around in the system to much as this is my one and only phone. But I would like to at some point.
But something I wanna know is this: If in flash CWM, can I use it without root? Say to make a backup of the stock rom before flashing SU? I only ask because I am currently at work and can't test the idea.
Another question is this: I know how to get to the stock recovery, but from what I read you use the VOL UP to get the "Menu". When I push any (hardware) button I get nothing and the image being displayed is an Android with a triangle and there is an exclimation point in it. Any thoughts?

a nandroid saves everything in your phone, just how it is at that moment. and when you restore it, your phone goes back to that very moment you made that nandroid backup. all your data remain. everything. its like you didnt do anything in between backing up and restoring

and you need root to use NANDROID? Or just an unlocked bootloader and to flash it over?

And CWM recovery.
You don't need root to backup but remember that when you reboot it will flash back to stock recovery (the triangle). You can simply repeat the adb command to flash CWM again.

So I could flash unlock my bootloader > flash CWM > Make a backup and save it to my computer then when i reboot my phone it would automatically reflash the stock recovery? and if this is correct, then all i would need to do is flash CWM to restore the saved backup?
So here's a question, is it the action of flashing SU that keeps the phone from removing CWM and reinstalling stock recovery?

You must rename the /system/etc/install-recovery.sh file or it will keep replacing the stock recovery. See this post, item 2.

How did you try to flash the RUU? You can not flash it like a normal ROM
Also if you are looking for the RUU try HERE
I see what you're trying to do, that won't work...you can't flash a recovery to get to stock because stock phone won't flash from recovery, which is why once you get root the first thing you do is flash a custom recovery. Use the RUU to flash it back to shipped state stock, or if you are trying to keep root and just want to use a different ROM. More clarification on what you are trying to accomplish would be nice.
If you did a Nandroid prior to flashing CM10 I would wipe all partitions except SD and restore the Nandroid, if all you want to do is get CM10 off your phone. Remember Nandroid Backups are your friend do them before flashing anything and save them to your PC if you don't want the SD space taken. Doing this has made flashing pain free and hassle free. If I don't like how my phone is running after a flash I can always get it right back to how it was when I was happy with it. Lastly there was a time when I had a Nandroid backup of a Sense ROM and was on AOSP and wanted to flash back to Sense, well my Backup wouldn't flash. After spending hours raising hell I did a clean install of the ROM booted once, then rebooted into recovery and flashed the Nandroid backup that had the settings I was using (when I was on Sense, it won't restore data and apps used on AOSP)...sorry if its not much help but more details are needed. But you have a starting point.

i have installed CM10 without backing up any image, therefore i cannot restore the orifginal vendor's rom. Nandroid back would have prevented this situation. the second problem is that I couldnt find any RUU for this phone. indeed the link you attached seems to have it bu unfortunately it is in chineese and after pushing all the buttons i couldn't download the file. so my options are
1- to pray that someone will be kind enough to publish it in a manner that it is accessible
2- I have a friend with a simillar phone , can i somehow back up hus rom and restore it in mine ????
thank

CWM Can't see my backup

I fragged up Android by applying an update, so I can't boot into Android.
I can get into CWM, but it doesn't see my backup... The backup is in /clockwordmod/backup/2013-03-17-14.09.00 . I can see it when I put my SD card in the PC.
However, CWM isn't finding it when it's in the device, and there's no option to direct CWM to where it is....
Solution anyone?

Bump....

Hi there!
What I can think of is first of all save your CWM backup to your PC.
Then you'd really have to flash a ROM to at least a version that will enable you to use the version of your backup: say if the ROM requirement that you had installed when you made the backup was 4.0.4 then install any ROM of that. You won't have to install any apps then.
You can then install X-parts from Google Play and with that CWM but that will not be a "stuck-on" CWM as any ROM upgrade will remove it BUT the beauty of it is that in your backup [which you'll then copy from your PC to the same folder you describe above make a Restore] you have the CWM that will stick and from there on won't have to worry.
Sounds like a bit of work but personally I don´t see a way around it...this is what I would do to get things as before.
Hope this works for you and do let me know.
Oh and don't forget to click THANKS.

Yea, what I ended up doing was installing a stock ROM, then installing Rom Manager. From ROM manager the backup installs no problem... But if booting directly to recovery, it can't find it, even though it's in the standard spot... It seems halfway pointless to me to have a backup that can't be restored from recovery... but who am I to judge :silly:

Okay... I think I found what the problem was. From within CWM App, I changed storage to external as opposed to internal, now the backups are found from recovery. Not 100% sure that's what the issue was, because I've wiped and installed a couple different ROMs since having the issue.

Having trouble reverting to stock rom on my shield tablet set to be killed

So when the whole shield tablet recall program started, I installed blisspop on my old tablet. Now I want to return that tablet to stock. I downloaded the 2.2.2 recovery image and tried to flash it off of a micro SD card through twrp, but I keep getting a error that's says failed to sysMapFile and nothing happens. How can I revert back to stock? And I picked 2.2.2 because I was worried about the killswitch, can I actually use the 3.1.1 image and then re root and remove the Tegra update file? When I return to stock rom, will I be able to reinstall a custom recovery but keep the stock rom? Sorry for all the questions, I'm pretty new at this. Thanks for the help!

Flash what ever you want in fastboot.
IF you let it boot make sure it's been factory reset, if it connects to WiFi your F****D.
From recovery delete the "TegraOTA" folder/apk from /system/app (or /system/priv-app, I forget). As long as you nuke the updater before it connects to WiFi you're fine.

As the poster above me said, you must flash this with fastboot.

You can use whatever image you want as long as you remove TegraOTA.

Yes, you can also just flash the custom recovery from fastboot when you are installing the custom ROM. Or you can just not flash a new recovery at all. If you leave your current recovery partition intact you can still flash your custom ROM using fastboot.
