[Q] How Do I Downgrade from ICS to Honeycomb? - Eee Pad Transformer Q&A, Help & Troubleshooting

Can anyone tell me how to downgrade back to Honeycomb or point me to the enigmatically-named forum post?
I'm running stock 4.0.3, kernel 2.6.39.4.
Please don't hang me if this is already on here somewhere. I did search, but all I found was version numbers and frankly, a lot of stuff I didn't understand.
From the Moderator: Doing a proper search will yield the right results. To find in a search you need to take your original query and then rearrange the word order sometimes to find. oka1
I recently did the OTA update to ICS. Since then I have had power drain, random reboot, and problems connecting to Wi-Fi.
Any help would be greatly appreciated.

Being you're on stock ROM, the only way is if your tf is nvflash compatible.
Serial # B60 or previous (some B70)

B50
My serial starts with B50, so I guess I'm at least in a good starting place.

Yes the B50 certainly is NVFlash compatible.
Here are a lot of NVFlash ROM, I don't see the latest HC (.21) ROM but try searching here or Google.

or it might update itself in stage up to .21 (not 100% sure on this)

Thank you, baseballfanz, that at least gives me a starting point.

Well, at least I didn't post in the developer's forum. Anyway, it doesn't matter how much you manipulate the search, it won't yield results that aren't on this forum.

Sorry, dude. But from what I found out today, it looks like anything above B70 is "in the works." Something should be out soon, but for now, it looks like you're stuck. I would check this post regularly to see if an update is available for later models.

I did that yesterday hoping that with a clean stock installation would fix problems (and it's working great until now, but as all we know problems come in a random way with ics).
So, I found on the net an nvflash 8.6.5.13 ww rom (full with bootloader, kernel and recovery).
Backup all your stuff first.
I booted into cwm, complete wipe, including /data/media.
Put tf in apx mode, nvflash complete rom, boot it.
After then I configured wifi and a notification about updates appeared. I did that and my tf was upgraded to 8.6.5.21 ww.
Then you can use that, flash cwm with nvflash, flash any honeycomb rom.
Instead I upgraded it with stock 9.2.1.17 ww rom (using official upgrade notification), because I want to see if it works correctly for me (100% stock without root, 9.2.1.17 is not rootable without flashing over a modified rom or with ota rootkeeper)..
Only time will tell if problems are gone for me on ics...

[Q] How to downgrade firmware

Can someone please tell me how to go back from .13 to .9 so I can root my TF please? So far I haven't found anything telling me how, just telling me it can be done. I got the old OFW from asus's website and moved it to the root of my SD card and tried a reload but still keeps loading .13 after the wipe.
So can someone tell me how or what I am doing wrong?
Just extract the contents of the .9 OFW into the root of your MicroSD, pop it in the Transformer and it should prompt you to update.

Ah cool, just open the zip and let me make the asus/update/... folders on the SD card and it will grab that one. Thanks.
Thank you, I felt so stupid and now it worked just fine.
I also want to downgrade from ICS back to Honeycomp.
Can i do that without root ? - just like an update -
And where can I download the de Version- on the asus webside is only theDE 4.0.3 version.

Would you consider giving the revolver ROM a try? I downgraded from 1.3.1 beta(ICS) to 3.11(HC).
I am fairly certain Asus like most device manufacturers try to keep you from being able to downgrade from official OEM versions of software back to older versions- the reason being, of course, that the newer versions sometimes fix software and security vulnerabilities (like 8.6.5.21 losing the ability to use an APK file to root, like razorclaw, and imagine a rogue application exploiting this vulnerability, achieving root, and broadcasting to the developer any information without notifying you about it..). The interesting thing is that the method of denying firmware 'updates' to downgrade seems to be arithmetically calculated from the version numbers, basically if update package version is < current version update will be denied. However, when they decided to engineer the update denial this way, it left it's own vulnerability, in that firmwares for the TF101G, being the later model of the TF101, automatically have a higher firmware version because of the 3rd digit is a 6 instead of a 5, indicating that the version is for TF101G. This left the old honeycomb ROMs with this vulnerability- if you had updated to 8.6.5.21, you were still able to 'update' to an older firmware the device viewed as 'newer' than the current device firmware, i.e. 8.6.5.21 users could update from a stock device to downgrade their firmware using the TF101G firmware 8.6.6.19, which could still be rooted with the APK vulnerability.
Now that we have moved onto ICS and there is not yet a TF101G version of ICS available, we lack this native downgrade option, and we are yet to see if Asus is going to fix this 'vulnerability' by simply amending the TF101G and TF101 version numbers, or by altering the way in which the OEM recovery mode accepts or rejects Asus update packages, I have the feeling that they already have with the 9.2.1.11 update recovery that was included.
All of the precursor information I just listed brings me to the only current method known to rollback your firmware if you are on ICS, either 9.2.1.17 or 9.2.1.11..you must root your device with ViperMOD, install CWM via RecoveryInstaller, and use CWM to manually install the firmware to a previous version. This will perhaps add a few layers of complexity..you may have to toggle signature verification and script asserts enabled (I am making a wild guess on this one, I've not yet tried to downgrade just yet), and you will be persistently bothered by Asus update notifications (there are plenty of threads describing how to rid yourself of these). My guess is that soon Asus will begin pulling the HC ROMs from their official website so you might want to grab that ASAP. And if you want to keep from getting bothered by update notifications yet stay stock 100%, you can (until they release the ICS for it) flash the TF101G version of the firmware, 8.6.6.21.
IN SUMMARY; to downgrade ICS to HC, you will have to root and flash recovery modes. There doesn't seem to be a way around it. And IMO it's probably best to NVFlash back to HC, no telling what kind of data will be left that will conflict with HC from ICS if you do simply flash a HC ROM via CWM. You will probably want to make sure you have the right kernel just in case you have to flash it as well..I can imagine a nightmare scenario if the Asus update didn't include a kernel that it leaves your ICS kernel intact, which will not load HC, and also flashes over your recovery, leaving you pretty much bricked without NVFlash. Fairly sure Asus update contain the full ROM- kernel included, but I always err on the side of caution..I'd flash the HC kernel first personally..just to be safe. If nightmare scenario does occur, you can't flash it after you reboot.

I had the revolver rom before- with my last transformer.- But ICS - if working, -is better.- and best seems to me: revolver rom ics based on a (good working !!) stockrom.
Meanwhile i rooted the transformer and install CWM - tried stockrom flashing with CWM- but because of usb is not working+ random reeboots, i changed to revolver ics- Revolver ics had a working usb connection (also random reboots- - and today a freeze while booting) .
I trie to find out the reason for the reboots.
I only go back to HC if there are too much problems with this rom - by i had to trie out first.

Kernel/ota questions

I've successfully recovered my tablet using this method. I was trying to update my TF using the batch script method and somehow managed to flash an outdated kernel. I know this because Asus tech support told me that was the reason my TF wasn't receiving the ota to 3.2. However, Asus tech support also told me that I could flash a new kernel by downloading the source code onto my tablet, then the TF would automatically recognize the [.rar] file and install my new kernel; which didn't work out as you might imagine.
I am now on official 3.1 8.4.4.11.and my kernel is v 2.6.36.3-00011-g3eb19ex And I can't get the OTA update. At one time I had official 3.2 [after previously flashing stock 3.1] but decided to try to root when I found out Netflix wasn't officially supported like the EEE pad site says it does.
Every time I try the batch script method, I end up stuck on the eee pad logo screen. Adb is working as well as apx drivers. Ultimate goal here is stock 3.2 rooted with netflix, but at this point I'd settle for stock official 3.2.
Any ideas? Tia

you could try the zip file from the thread titled [OTA]Stock 3.2 zip file

I would suggest you to try Nvflash. it is the easiest way to root that tf.
I think the relationship between nvflash and the TF is complicated.
There are a few bootloaders out there, including the one used by custom roms, as well as the 4 stock ones.
My theory is that the kernel images in the boot and recovery images have to match the bootloader that is on the TF.
Throw in the fact that the bootloader is only written using the nvflash --create command or during the OTA update, and we have TFs with all kinds of different bootloaders going around that won't match what people are flashing. I think this is why CWM breaks whenever there is a stock OTA that rewrites the bootloader. I think most people brick trying to go back to stock from a custom rom. Going from stock to custom usually isn't a problem because the compatible bootloader is flashed in the rooting process.
Is this the first time we've seen an completely unlocked bootloader on Android?

Use the NVFlash unroot method here:
http://tabletroms.com/forums/showthread.php?1071-Asus-Transformer-NVFlash-Stock-3.1-Recovery-Roms
That will get it back to stock everything with 8.4.4.5. Then, you can manually install 8.4.4.11 with the download on the Asus website. After that it will recognize the OTA update to 8.6.5.6. Once you've done all that, use the Batch Script for a quick root, and you're done. I did this today. As long as you follow all the steps, it's a breeze.
I don't think it will recognize the OTA update to 8656. Roach's update will work, but not the stock update.

It will recognize it, because if you follow all the steps I listed, you're completely stock until you run the batch script to root 3.2. I did this myself on my transformer today.
My OP is not very clear, but that is exactly the steps I've followed to get to where I am today. I've given it 2 days to detect the new update and i've got nothing. I'm currently sitting on stock 8.4.4.11 waiting for the OTA.

Help with unrooting and making OTA updates work again?

Hello,
Well first off, I have unrooted the tablet already (I think). I followed this guide here:
http://forum.xda-developers.com/showthread.php?t=1154947&highlight=easy+unroot
I would have posted my question there, but apparently this forum wont let me post there since I do not have 10 posts yet.
I currently have version 3.2.1 installed, have the stock recovery installed, and do not have superuser showing in my apps list.
However, I am still not getting ICS OTA update. So I can only assume I've done something wrong.
I realize I can simply download ICS firmware update from asus and update it the same way I did 3.2.1 after unrooting, however that wont work. I'm trying to make sure OTA updates are working because I'm giving this table to my computer illiterate sister and need updates to work OTA for her.
Thank you for any assistance!
Asus pulled the OTA ICS update because of reported widespread problems with it.
Hello Steven6282,
any luck already? was ICS cancelled by asus?
Maybe the solution I mentioned in the post below will help?
http://forum.xda-developers.com/showpost.php?p=19468648&postcount=7
on that forum they have stock 3.2 Build of 8.6.5.13 in nvflash. But his depend if you are able to use nvflash (serial number of your tablet)? I used this method and then ota also works again. this way your tablet is really stock without tweaks.
goodluck.

TF101 Honeycomb updates

Does anyone know where I might be able to find the latest of the Honeycomb updates? I've got the 8.6.5.13 NVFlash, but I've been searching and haven't been able to find any of the 'Official' updates. It doesn't help that searching XDA for '8.6.5.19' actually searches for '8 6 5 19'. I believe the latest is either 8.6.6.21 or 8.6.5.21? If someone could point me in the direction of the latest (or two latest) oficcial Asus Honeycomb updates, I'd appreciate it.
Hi Subnetmask (255.255.255.0)
Why dont you just use ota from asus? are is your TF rooted and CWM installed?
Otherwise use gnufabio's recovery installer app to install cwm so you can upgrade.
or use nvflash to install ICS????
It looks like he wants to downgrade, or only upgrade to the latest HC and avoid ICS. I'd link you to the download from asus on their site, but of course it's down -_-
When the site is back up it should be on there. If not search for 8.6.6.21 stock rooted tf101 or along those lines.

That's exactly it. I downgraded to 8.6.5.13, but don't want to upgrade it to ICS again just yet... SInce I downgraded it to 8.6.5.13 it hasn't shut down on its own again yet (Big surprise...).
I looked on Asus' web site, and unless there's another section I couldn't find, the only non-ICS download is 8.6.5.13 for the 'CN' SKU. I've searched around Google and unless I"m missing something (always possible) nothing useful has come up yet. Searching here is kinda useless because '8.6.5.13' gets searched as '8 6 5 13' so pretty much any thread with an 8, a 6, a 5 or a 13 gets displayed :/.
I have a copy of Stock 8.6.5.21 (latest HC). I can post it up once I get to my PC.
Probably be a couple of hours.

Anyone have 8.6.5.19? I don't know why I'm having so much trouble, but I can't get my TF101 to re-root for the life of me. I've tried on the bare 8.6.5.13 & with 8.6.5.21, with ViperMod, NachoRoot and Razorclaw. .13 is too old and .21 is too new for Razorclaw, Nachroot by it's self didn't seem to work right, and Vipermod, using option 3 didn't seem to work either. The problem with ViperMod was when it came back saying UID should be '0', it was always '2000'. If I cna get .19, I should be able to use Razorclaw, then rootkeeper, and update to .21. Then I just need to make the Asus update prompts go away...

Don't know why I'm having so much trouble rooting the thing... I've done it after every release since I got it. I must've just gone stoopid lol. Searching for root give ICS information overload.

It doesn't matter if it's WW or not. your goal is to get root and after which you can flash the correct version for your region.
If it work and you get root, use OTA Root Keeper to save your root, upgrade to 8.6.5.21 and restore root. Worth a try
Finally got it rooted... After about an hour of searching, I found the method that I had originally used (the 'One Click' root found here). I installed OTA Root keeper, but that didn't work on my upgrade to .21 from .9. I ended up having to re-root, but since the 'One-Click' worked, it wasn't too painful. Using linix to root it is so obscure (to me) I totally forgot about it.
Still, if someone happens to have the 8.6.5.19 update file (Call me wierd, but I'd rather have/use the proper file for my unit rather than the one for the TF101g even though it may work fine), it would be great to get that to add to my 'collection'.

How to update to Jelly Bean?

Before anybody says to use the search function, I've been looking through the general topics non-stop for one that applies to my situation, and either it slipped through the cracks (likely) or it doesn't exist (not likely).
Basically, my tablet is rooted and unlocked, and I'm on ICS; the first one that had face unlock in it. I'd really like to update my tab to JB, but I need to be pointed toward directions for updating a rooted and unlocked tab. But on top of that, I also need recent instructions, because I know that earlier attempts at getting this thing updated have resulted in lots of bricked tabs.
If anybody could tell me if it's possible to update my tablet to JB right now, I'd appreciate it, and if someone has figured out how to do it, can you please point me toward that thread? I'd really appreciate it.

I'm in the same configuration, custom-ics-rom with twrp recovery on unlocked device.
I believe the first thing to do is enabling NVFLASH, that will make things safer also in the worst cases.
I did that and now hopefully I have an unbrickable device.
I'm a bit confused on how to go forward, I know that there are two versions of twrp, maybe I should install the JB version, booting inside it and then flash the downloaded JB update from ASUS site, or use the twrp for ICS for flashing and after that install the JB version ?
Anyone knows what is the correct option ?

Keep ICS, as JB will cause much trouble especially if you are rooted, trying to OC and is generally slowein my opinion
I prefer to try it anyway, tomorrow I will try flashing, after all if something will go wrong I should be able to recover with nvflash.

Thank you, Grim. That's disappointing to hear about JB, but if you think that my current build is better than that (which makes sense considering I've seen at least one thread about downgrading from JB to ICS), then I will keep my tab on ICS for now, and thank you for your input, I appreciate it.

If you have twrp recovery, can't you download the jb ROM from the Asus site for your region and flash it in? I'm unlocked and that's how I upgraded one version of jb to another, but my ICS to jb was ota, so in your case I can't speak from experience. There is a full upgrade, and root guide in the general section.

I just managed to do what you re looking to achieve.
I m pretty noob so it tok me a whole day to figure it out.
So first download jb update on asus website (pick the right one for ur type of tf300)
Flash it through adb
At that point i got jb installation working but bootloop
So i flashed jb version of twrp (adb)
I then went in recovery and flashed clean rom 2.5 which worked flawlessly
Just for the fun i did factory reset afetrwards and stock jb eventually launched right

I successfully installed jb following the guide on this site, the only thing that was not working was the flashing of the stock rom, neither given options worked (fastboot flash recovery or fastboot flash system) , I discovered that our eepad has a partition nmed staging used for firmware installs. I then flashed with
fastboot flash staging blolb
and all went good.
Btw I find the JB better than ics, more responsive and smoother, and also if it is not yet overcooked.
