[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

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.

[Q] CM7 / ICS Flashing issues

I soft bricked my phone playing with ICS, I got a JIG and solved the problem
I can now ODIN back to any version and once rooted I can install any samsung based rom, the problem comes when I try to flash aosp both CM7 and any ICS beta
What happens is I select the zip, it runs a script and the phone reboots, I see the AT&T logo and then it mounts the sd card, it says it can't find the zip file.
I've tried Froyo, Eclair, even gingerbread (I know your not supposed to flash cm7 from gingerbread, I'm just running outta ideas) I have froyo bootloaders, I reinstalled them with heimdal. I've also done a master clear and erased the internal sd card
Does anyone have an idea of why this is happening?

Are you trying to install the zip from ClockworkMod?

Most likely, the rom is incompatible with the flash method you are choosing which bricks your phone. I had this happen to me twice from either flashing a rom the wrong way or just trying to flash the wrong rom all together and killing my system, but I ended up telling AT&T Techs that it happened when I tried upgrading to 2.2 to avoid warranty issues and they replaced my whole device with a refurbished unit =]
However keep in mind that they cannot jig your device and you will have to do that yourself to get your data off your device before you try getting a new one via this method.
Possible Solution:
1. If you can, flash cm7 to your device
2. Flash This ICS rom

If you have already tried this then I apologize, but I hope this helps.

Another problem
Ok, everything I see says I should flash from a captivatemtd recovery, but when I install Rom manager and select captivatemtd, it says their are no offical recoveries for it, I'm currently running cognition froyo 2.2 with froyo bootloaders
Does anyone know where I can manually get the captivatemtd CWM? and how do I install it?

I'll go over my method of installing(I've had ZERO issues flashing from/to any ROM)
1. I FTS/MC using Odin 1 Click. My phone build is 1008
2. Root with 1 click root(I have to do steps 2 and 3 because I do not have 3 button recovery)
3. Sideload and install ROM Manager(Rom manager, and CWM update.zip are in the Sideload zip that's attached)
4. Copy CWM Update.zip and ROM to device. Reboot and install CWM
5. Reboot into recovery and install ROM
Odin 1 Click(If you can use it)
http://dl.dropbox.com/u/12100225/Odin I897UCJF6-final-OCD-REV0.zip
Root 1 Click
http://dl.dropbox.com/u/12100225/Root.zip
Sideload Wonder Machine and ROM Manager
http://dl.dropbox.com/u/12100225/Sideloading.zip
Edit** What is the build number of your phone?

Here's what you need
Just download this rom
http://download.cyanogenmod.com/get/cm_captivatemtd_full-181.zip
And then watch this video!
http://www.youtube.com/watch?v=iBPu-GqM9RE
Flash CM7 using odin
then flash ICS using clockwork mod using the instructions I gave you before.
That's the easiest way I found to do it and that's how I went from stock rom to CM7 rom and then finally to ICS

Tried this to the letter still doesn't work, could it be because of rom manager not finding a recovery for captivatemtd, some pages say I need that recovery but it isn't available in rom manager.

Finnally
Finnally got CM7 installed the problem was I had to do the three button boot into recovery twice, the first time updates clockworkmod to version 5.x
Now to try ICS again, wish me luck

Thanks
Thanks for all the suggestions, the tip in the video about flashing the speedmod kernel did help I think, I've successfully flashed
teamhacksung's ICS Port for Captivate (BUILD 9) again.

A couple notes here:
1 when your flashing cm7 from cwm( NOT 3e RECOVERY THOUGH) you need to flash the. Zip file, then reboot system, IT WILL PROBABLY BOOT LOOP, three button back to recovery and flash again, then while in recovery still flash gapps. Reboot and it will install fine. You should ONLY need to do the two time flash the first time going to cm7.
2. When you go to rom manager and choose manual flash overide from hitting the menu button you will get the unsupported recovery, DON'T WORRY about it and hit ok. Then another popup will come up and choose 3.x and it will work.

[Q] ClockWork : upgrade, downgrade...

Hi there!
I'm a owner of a TF101 (B50) for month now, and recently I had the need to switch between multiple version of Android (as I'm an Android dev) : back and forth to/from Honeycomb from/to ICS for example, multiple time a day!
So, as I'm used to do with all my "Google's Experience" devices (Nexus S, Galaxy Nexus), I installed CWM on my TF101 to be able to generate nandroid. So far, so good.
I then downgraded my tablet to stock 3.2 using nvflash, installed CWM, and did a nandroid. Great, I now have an Honeycomb backup. Of course, at this point, I'm no more able to upgrade using OTA, so here's my first question :
1- Once CWM installed, how do you upgrade to the latest build ? Asus blobs are not compatible with CWM!
Then, since I needed an ICS nandroid, I reverted to stock 3.2 (using NVFLASH), and I let the OTA did the job for me - before installing CWM. Ok, now, I have both Honeycomb and ICS as backup : let's test that.
I rebooted in recovery, and then restored my 3.2 nandroid (from ICS, remember?). All I had once the job was done, was the android logo with an exclamation mark
After some Googling, I understood why : unlike my Google's devices, on the TF101, it seems CWM can't restore the boot partition. So, the bootloader used was the one for ICS, and the tablet failed to boot.... Here's my 2nd question :
2- Am I right? What guys are you suggesting to be able to switch easily between different nandroid versions ? Should I nvflash the boot partition by hand? If so, where to find a documentation on NVFLASH ? (I'm regretting fastboot )
Thanks for reading.

You can repackage the blobs so that they can be flashed from cwm. I think one roach's 3201 recovery is packaged this way, so you can take it apart to see how it all works. Essentially blobs are flashed through the staging partition. There is a blob tools thread in the dev section that has all the details.
If you want to go back and forth between roms, I think that nvflash will be your best bet. Rayman and bubble bee have the most info. Check out therenwebsite. It's something like androidroot.mobi? There is also a full backup and restore thread in the dev section that explains a lot of the details of nvflash.

I read, somewhere, that we can flash stock Asus firmwares using CWM ('update zip') by first extracting the initial zip (which contains another zip containing the blob). Is it true?

yes but you will loose root and cwm recovery. It's the easy unroot method.

Not a big concern. I can easily recover both root and CWM using the universal root method since I have a B50!
Thanks

Will you lose root/cwm even if you have OTA Rootkeeper installed?

You Shouldn't but no guarentees x)

need help understanding how to root....

ok so ive searched everywhere and tried reading everything but im very confused. i see that it is going to be very hard to root my tf101 since i have the latest asus ota update (build #9.2.1.24) but i cant quite wrap my head around how to do it.
i tried using the backup exploit and sparkyroot but those dont work on the latest ota. i already have Rom Manager installed and tried the recoveryinstaller.apk from Gnufabio but those didnt do anything either.
iv read the thread about downgrading (Wolf's guide) but im hesitant to do that since i dont understand it and i have no experience using the shell command (is that the same as using a terminal emulator?) can anyone please explain the terminology and how to downgrade? what program do i need on my computer (running windows vista)? please be gentle and dumb it down for me and include any links to programs or files i may need
thanks so much
p.s. is a "Blob" the same thing as an SBF? and if i did a factory data wipe, would that downgrade from ics 9.2.1.24 or keep it the same?

Adb shell is the same as running a terminal emulator, just google android sdk download and click the first link. Follow wolf's instructions carefully using your favorite recoveryblob from the development and you should be perfectly fine. Never use Rom manager, please just uninstall it now. If you factory reset, the recovery will still be there, as a reset only deletes user data, to return to stock you would need to flash stock recovery over cwm (not recommended) or flash a whole ASUS ota package from their website (better, removes any root and rom you have, cross that bridge when you get to it) What are the first 4 digits of your serial number? (for ex: mine are B70K) If they start with B60 or lower (B50,B40,etc..) you can just use NvFlash instead of having to use wolf's guide to root. Don't be too scared, it isn't that bad, just follow instructions carefully.

Thanks for the reply. My serial is b60. After more searching I was able to find an adb dummies guide and was able to downgrade to .17 but I didn't read one extra post to see that sparkyroot doesn't work with .17
So I had to do it all over again and go down to .11 and that worked and then I used sparkyroot and voodoo ota rootkeeper. Will rootkeeper work/stay if I do a factory reset? Cuz some apps and services aren't working. Or should I just do the ota to .17 and then .24? And now I can use nvflash in order to flash a new rom? Is that in the market or just google it?
Thanks again

You didn't need to go through all that since you have NvFlash, but good learning process I suppose
At this point, since you're rooted, use recoveryinstaller again to install CWM recovery, download a kernel.zip (I recommend Guevor's kernel) your favorite ROM .zip, and a new recovery.zip (as 3.2.0.1 works but is pretty outdated) [OR you can go to team rouge's thread in dev for an NvFlash version of recovery and NvFlash instead of recovery installer and update, then apply rom and kernel .zips in new recovery]
Make sure to place the .zips on external SD card if you're using 3.2.0.1. Any other Qs?

NvFlash: http://forum.xda-developers.com/showthread.php?t=1123429&highlight=nvflash
Rouge Recovery: http://forum.xda-developers.com/showthread.php?t=1446019

when you say that recovery.zip 3.2.0.1 is outdated do you mean the CWM version?
is flashing a new kernel safe? this is obviously my first time with a tablet with so much "freedom" compared to my droid2global lol
personal opinion, what do you think of android revolution rom? any other recommendations?

Yes the CWM version, I did use 3.2.0.1 for awhile though, it works, it's just old.
Yes, flash away, just always remember to wipe cache and dalvik-cache before flashing anything.
Android revolution is a great stock based rom, if you like the tab the way ASUS sends it too you, I personally prefer AOSP based roms, so my other recommendation if you want to go that route is Megatron or AOKP Build 37
Guevor's v20 kernel is the best out atm, imo.

[Q] Can't Flash ANYTHING!!!!

Every time I try to flash something my tablet fails, and I have to revert back my backup. It doesn't matter if I download on PC or from the tablet itself. HELP!!!!

Can you post what rom you are using right now, as well as what recovery version.
Also, what rom are you trying to flash ? You are rooted, right ?
If you can post some more details - am sure people will chime in
Good luck,

I'm running stock 4.0.4, Rooted, Clockworkmod recovery. I have tried to flash several different roms. Romswell, AOKP, CM nightlies thru ROM manager. all of them fail in recovery. I flash stuff all the time on my SIII so I'm not really a Noob to flashing and what not, but I can't figure this one out. Thanks for any help.

What are you using for recovery? When you say failed what is the error message? Sounds like you should prolly reflash a current official recovery. If by failing you mean it hangs on first boot then your not wiping system before flashing. Factory reset and wipe system before you flash.

Are you by chance running any scripts for sd card swap, etc ?
I am running this script, http://forum.xda-developers.com/showthread.php?t=1961097 which swaps my 32GB external sd for the internal sd, which runs great - no issues, except with rom manager and flashing from recovery.
I have to go back and de-activate the script, reboot, and then dowload - or transfer file from PC, and it flashes without issue
Otherwise, I have had no flashing issues of any kind - using CWM 6.0.1.5 for the p3113
Good luck,
Bill
