Did everyone have to wipe downgrading from .21 to .15?
[Asus  Eee Pad Transformer Prime] maatsby:
before or after downgrading?

i've read people have had to wipe /data after downgrading from ICS to HC
[Asus  Eee Pad Transformer Prime] tsmt971@yahoo:
It is working like charm. I did successfully downgrade to .15, root and back to 2.1 without forgetting to backup root with OTA Root keeper. I can say now I am rooted. Thanks so much.
[Asus  Eee Pad Transformer Prime] collinsac24:
i did not have to wipe
[Asus  Eee Pad Transformer Prime] collinsac24:
temp unroot is not needed
[Asus  Eee Pad Transformer Prime] currydude:
Both lol

ol cool thanks

Thanks for the confirmation without root I have no backup so I don't want to wipe lol
[Asus  Eee Pad Transformer Prime] Shinare:
Any hope out there for a utility or one click for us not so competent users out here? Heh
[Asus  Eee Pad Transformer Prime] neo1738:
Not as of right now because the root method only works before .21 which means you have to downgrade 1st.

Also according to some devs they aren't looking at ruining their exploits (secrets that will get patched by oem's again and again) on the TFP since we have halflocked bootloaders (technically unlocked but with some restricitons) so you can get root by putting on a custom ROM that way.

Basically don't hold your breath right now there is no reason for the dev team to divulge their secrets doing this for .21
[Asus  Eee Pad Transformer Prime] collinsac24:
Update should be very soon right? With nvflash I believe it was
[Asus  Eee Pad Transformer Prime] hajalie24:
I downloaded .15 WW version and noticed I can't receive the OTA update. How exactly should I update to .21 US? I remember reading somewhere its best to do it OTA but I can't do that...
[Asus  Eee Pad Transformer Prime] bpear96:
Probably because you used WW on a US prime.. you could try going back to .15 using http://xdaforums.com/showthread.php?t=1492887

[Asus  Eee Pad Transformer Prime] bpear96:
No problem glad to help out :D, also i think google docs/drive might be alittle faster but im not sure lol
[Asus  Eee Pad Transformer Prime] Danforth:
Thanks to Wolf for the exploit, and ucfstevie for helping to spread the word.

Success, and didn't have to wipe. Downgraded to .15 TW, rooted with the Sparkyroot app, backed up with OTA Rootkeeper, OTA to .21, then finally restored root with Rootkeeper.

The only hard part for me was trying to get into the ADB shell! Hadn't used it before, and didn't realize that I needed USB drivers from Asus -- I just assumed the ones in the Android SDK were all that were needed.

Rooting is especially useful for me here in China, because it allows me to use a certain VPN app on my Prime so that I can access Facebook from behind the Great Firewall. (After I lost root with .21 I was forced to use my Windows laptop for this.) Love you guys, haha!

ViperMODS tool, modded to add Wolf's no root downgrade

ONE CLICK Downgrade, using Wolf's method and root tool (thanks to viperboy)

​

I modded ViperMods awesome prime tool, to add an option to one click downgrade, using wolf's no root method :D. Just put the blob of FW you want to go to on the root of your primes internal memory, then run option 1 on my modded vipermods tool :D

99.9% credit go to -Viperboy- and Wolf849 :D i just added option in viperMOD's tool

Modded app didn't work for me, here's what it said:

* daemon not running. starting it now on port 5037 *

* daemon started successfully *

ECHO is off.

Step 1 - Preparing for downgrade...

Step 2 - Rebooting..

Step 3 - Moving FW data...

/system/bin/sh: /data/local/installbusybox: not found

/system/bin/sh: /data/local/root: not found

Step 4 - Cleaning up... (this will take 3-10min)

Once your Prime reboots, it will be on .15 ready to be rooted Enjoy :)

Thanks to wolf849 for this downgrade method!!

[Asus  Eee Pad Transformer Prime] hceuterpe:
Anyone try this method with storage/device encryption enabled? Wiping required?
[Asus  Eee Pad Transformer Prime] slayvus:
I wouldn't try it with it enabled. Something might go horribly wrong. Backup everything and remove encryption.
[Asus  Eee Pad Transformer Prime] velow:
Had lost root thanks to asus technical service, made me update again to .21 by zip file, they didn´t resolve my problem (couldn´t install more apps) and lost my root, imposible to recover it even with my backup of root with OTA keeper. This method works!!!! My Prime downgraded and rooted again, backup of root with OTA keeper, now i´m going to update by OTA to .21 again and recover root. Thanks mate!!

Now updated by OTA to .21 and rooted again.....:)
[Asus  Eee Pad Transformer Prime] haberbe:
going to downgrade to root soon. probably this weekend.

quick question, does this method result in wiping the tab? will i have to re-install everything again? or is it like an OTA, where all my prior stuff is kept intact?

just trying to get a feel for the ammont of time and effort i will have to put in when i pull the trigger.

Thanks
[Asus  Eee Pad Transformer Prime] svladimir:
Guys a quick question: now since I've successfully rooted my prime, how do I install custom roms/kernels ? My understanding is that in order to do that I gotta unlock the bootloader (to install CWM). And this's something I'd rather not to.

Any info would be very welcomed
[Asus  Eee Pad Transformer Prime] MegaPantheR18:
Can I use it to downgrade:1) to WW, DE regions?

2) to Honeycomb?
[Asus  Eee Pad Transformer Prime] bimbobo:
Same question here because option 1 says "downgrade from US to 15." what about if you have 21 with other SKUs?

In my case WW21

Thanks anyway for this new great found.

---------- Post added at 09:39 AM ---------- Previous post was at 08:56 AM ----------

This new tool does not work for me.

It reboots after choosing option 1, but after the process is done and another reboot occurs, I am still on WW 21 not rooted. and not downgraded.:(
[Asus  Eee Pad Transformer Prime] Mekrel:
1) Yes, you just need the blob file for that region, i.e. if you want to downgrade to DE .15, you need the DE .15 blob file.

2) Yes, you can downgrade to Honeycomb as long as you use the Honeycomb blob file but as you're downgrading from ICS to HC; you're goning to have to wipe as the frameworks differ so much.

You can get any blob file from any firmware, as long as that firmware is still listed on Asus' website for download. Just extract the firmware using an archive manager such as 7Zip and you'll find another .zip inside which will contain the blob.
[Asus  Eee Pad Transformer Prime] bimbobo:
It did not work for me, I put steps and screenshot in the other thread where the tools is explained.

I went from .21 ww and back keeping root. No user data wiped. Easy process - just make sure you follow the instructions I used the modded vipertools by bpear.
[Asus  Eee Pad Transformer Prime] bimbobo:
I did it nothing happens, there is something wrong, even though I followed the procedure and no errors can be spotted.

It seems like it does not catch the new blob on the sd card
[Asus  Eee Pad Transformer Prime] currydude:
Says signature failed verification during installation process? Could it be the file downloaded from google docs? Going to try another mirror

EDIT Nevermind, might be because of WinRar, try 7zip guys, I got a different md5 reading using 7zip

EDIT: nevermind, it was Filezilla, best way to transfer is to move it into a microsd and then transfer the blob file over using stock File Manager to /sdcard
[Asus  Eee Pad Transformer Prime] MegaPantheR18:
Thanks a lot! I was able to return to Honeycomb!! I put blob into internal memory and it worked!

P.S. Accelerometer works in Glowball and Temple Run(didn't work on ICS)
[Asus  Eee Pad Transformer Prime] maatsby:
or u could use "adb push blob /sdcard/blob"

It takes a little while cos its so huge but it gets there in the end
[Asus  Eee Pad Transformer Prime] currydude:
Or that :P
[Asus  Eee Pad Transformer Prime] Mekrel:
Why use the tool? You're better off writing the commands yourself.

Since getting involved in Android, I've installed Linux (I recommend Ubuntu for new users) along side my Windows install and I find using ADB is far more reliable on Linux than Windows.

It takes a few steps to setup, such as editing udev rules for your device but once it's all done; it's much easier.

Once you've got a working Linux distro setup with the Android SDK tools working (such as ADB) you'll find you'll never have to wait for another tool again.
[Asus  Eee Pad Transformer Prime] bimbobo:
OK it worked now! The SD Card needed to be reformatted.

Now I am on 15WW, rooted and I saved the root on OTA Root Keeper.

BUT! why in the apps. list I can only disable stuff and not uninstall?

For example Vibe or Gmail or other Google apps.? I can only disable them.

I will also try to install WW21 again and see if OTA RK saved can restore the root, without unlocking or else.

---------- Post added at 03:00 PM ---------- Previous post was at 02:27 PM ----------

Installed 15WW

Rooted with OTA RK

Saved Root

Installed 21WW

Restored root with OTA RK

It says root restored.but it's not rooted at all.

I spent 2 hours uselessly! (even if the tools worked).

How come some people reported that now they have 21WW rooted?

It did not work for me, as I wrote in the early post :(
[Asus  Eee Pad Transformer Prime] sontin:
Rootkeeper is only working when you update per OTA. It's useless when you using the manual update... :(

How did you upgrade to .21?

1. settings-> about tablet-> Software Update

2. upgrade from a file: WW_epad-user-9.4.2.21.zip
[Asus  Eee Pad Transformer Prime] casey225:
You have to do OTA update to keep root. As a matter of fact, as soon as the final boot was complete from the downgrade, the .21 OTA immediately started downloading. I rooted and protected before the download was complete just to make sure I didn't accidentally update again. Once it rebooted with root, the download completed, I installed the update and had .21 with root.

---------- Post added at 10:33 AM ---------- Previous post was at 10:26 AM ----------

One minor detail is that when I first tried titanium backup, it told me SU didn't have proper permissions, or, something to that effect. I still had SU app, from previous root of .15 that I never uninstalled. TB will offer to fix it for you, which I did, and I haven't noticed any other problems. SU Upadate Fixer app doesn't detect any problems either. Looks like we're good to go.

[Asus  Eee Pad Transformer Prime] johanjonker:
Firstly.. thank you

I'm now rooted on. 21

I didn't loose anything from the downgrade - root - upgrade..

It wassnt easy to get the files. Since most download link from the US is blocked.

But other than that.. I'm one happy rooted TFP user..

And to think of it the only reason I want root is for proxydroid.. but now ... (evil.smile) i have it all.
[Asus  Eee Pad Transformer Prime] osunsanseun:
Does this method also void warranty?
[Asus  Eee Pad Transformer Prime] flyingwolf:
This method does not void your warranty, you are only rooting and not unlocking so you are fine.

Did you install the same region as the tablet originally had? i mean, if you had a US prime did you install the US .15 or the WW? Because i think for it to work properly you have to have the same region

Yah I made sure it was US .15 and even made sure the tab was on us version of .21 before I downgraded.

There's an app in the development section (at least that's where I think it is) called ATP Tweak. I read that using that to load CFQ io scheduler and setting it as the default scheduler helps. I've done this and it does seem to help, I've definitely not had as severe lock ups but it's a strange one as noop and deadline schedulers are supposedly best for flash storage and noop is the default scheduler used on the Prime.

I got the TF101 and the only issue is that the .15 blob will not work (for the tf101 obviously)

Glad it worked for you :) maybe that is also the case with tf201.

[Asus  Eee Pad Transformer Prime] jasonftfw:
Figured itd be good to share since the tool mentions the tf101. That way if someone with a tf101 reads this, theyll know what to do. Took me some time myself to find this thread and then find a blob that worked.

Thought I would crosspost in this thread since the question in the original thread isn't bearing fruit.

I was able to downgrade to .15 using the tool. Rooted fine, voodoo'ed the root and checked for updates to get back on .21. I was able to get the update notification and downloaded the update. Told it to do it and it rebooted. Went to the android guy with the spinning wire mesh. Got about 25% on the progress bar and then the guy was on his back with a triangle and an exclamation point in his open stomach. Stayed there for maybe a minute or two and then by itself rebooted and went back into .15 saying there was an error and reverted.

I downloaded the update a second time in case it was a bad download and got the same result. Another user in the other thread on the tf101 is having the same issue and wiped everything and it did not resolve the issue.

Any ideas would be greatly appreciated. I would like to get back on the update path.
[Asus  Eee Pad Transformer Prime] pbelcomp:
When .21 first came out, I remember seeing a post telling people to look in a log to check and see what the error was that stopped the update.

If you know what the error is, you may be able to fix it.

I can't find the post right this second but maybe someone remembers what log to look in.
[Asus  Eee Pad Transformer Prime] buxtahuda:
Sounds like some system files/apps have been changed/removed. The build.prop is usually one of the most obvious culprits.

Use Root Explorer or another file manager to locate the /cache/recovery directory and copy over the two contained files (I don't remember which one you actually need to look at) somewhere to the root of your (m)SD card. You should now be able to open up the file(s) and find where the issue is.
