Downgrade ICS TO Honeycomb - Acer Iconia Tab A100

Hi, I would like to downgrade from ICS Honeycomb, given the bugs of Android 4.0.3, I explained how to do?

Same way you installed the leaked version of ICS. Download the 2007 build of HC for the A100, put it on root of your SD card, boot into recovery mode and the tablet will do the rest.

impossible, currently.

But you can do or not? I downloaded the version of January 2012, when I put the root of your SD card, rename to update.zip and flash, does not work?

So, you installed a leaked alpha ROM without knowing what you were doing or how to roll it back?

So does not help anyone. I installed it knowing that it was enough to downgrade the rom official Honeycomb, copy it to your SD and install via external recovery, sought confirmation.

EMEA_GB Firmware

Hi Everyone,
In preparation for the official release of the ICS update on the A100, I was wondering if anyone on this forum is still running the Honeycomb EMEA firmware, and if they are, one the firmware upgrade rolls down the pipe, can you take a backup of the upgrade zip? Also, if anyone has the large update zip file for EMEA_GB firmware, I would be interested in that as well. Thanks in advance.

I downgraded my A101 to EMEA GB ROM from this post http://forum.xda-developers.com/showthread.php?t=1307046&page=13
It works fine.
If you don't mind having 3G related stuff installed, it should work on A100 too.
Thanks, but I want to play it really safe and get access to the exact original ROM that I had originally. Does anyone else have the original A100 EMEA_GB Honeycomb 3.2.1 update zip? I also have backups of all the partitions on my tablet but don't have a recovery shell installed to be able to dd the images back... any ideas?

I was able to restore the original HC firmware with DD Images I took before I upgraded the tablet. I think I'll stick on HC for the next little while.

Got OTA notification but....

...I downloaded the 4.0.4 update and went to install and reboot. But the phone got stuck at the screen with the android belly up and a exclamation point. Pulled the battery and rebooted and was at 4.0.2 still. Haven't gotten another OTA notification. Do I get another OTA alert or do I have to update manually.
I have a GSM Nexus, rooted but with stock 4.0.2. And I activated OTA RootKeeper before downloading the update. Any help will be greatly accepted.

Besides root and maybe unlock your bootloader, did you change anything in your system (install mods, different radio etc. or rename system files)? If you are not completely stock your OTA will not work and you will have to update manually or get back to Stock first.

Nothing changed. Except for root and unlocked bootloader everything is stock.

Well the screen you were looking at (Android belly up) is the stock recovery. If you see that: no need to pull battery. Simply push volume up + power simultaneously and you'll get into the recovery menu. Scrolling through the options can be done with the volume buttons, select with the power button.
That said: I think no one knows for sure but I myself would not wait and update myself. There are a lot of guides here on how to do that and if you flash the stock images you will have the same as anyone who had the OTA. Make a proper backup first (you allways should)! You will lose all your data if you have to unlock your bootloader.

Have you installed CWM recovery installed?
The "belly up" android is the phone trying to boot in the stock recovery to update the phone. But as you may have CWM recovery installed (which replaces the stock recovery) the phone cannot complete the update.
You will need to re-install the stock recovery. I believe you can do this with the GNex Toolkit.

Is it possible to get the Stock Recovery Screen when you have CWM installed? Didn't think that was possible... that it would just boot into CWM recovery. That is why I didn't mention it (trying to learn here).
Same problem here. Stock 4.0.2, rooted, CWM installed.
Does this mean we will lose settings before we are able to update the device?

this mean you are not eligible for the OTA update mate, because you have a custom recovery
i suggest you to
flash the stock rom manually
flash a custom rom wih 4.04 inside
my 2 cents

custom recovery is needed in order to install custom ROM dude, is quite simple
and yes, you can root the stock ROM without custom recovery, there are a lot of guide about that in the developer section

So my only option to fix this now is flash 4.0.4 manually (will I lose stuff?) and then root again and get stock recovery back? Sorry for my n00b questions, thanks for your help!
Edit: would it be easier if I just get the stock recovery back and then try to get the OTA to turn up again?

Thank you master for your soothing words. I just want my Galaxy Nexus to be like he is right out of the box, but rooted. Thats all I need from him... I am guessing my girlfriends Nexus S is going to be a pain in my assholes in a few weeks bc its still on GB and my TF101 will also go haywire because of my rooting adventures...
First this GN nuisance... Guess I am going to have to wait until tomorrow, I am flying to Dublin in about two hours and I don't think I can fix this in time...

i agree, take your time and you wouldn't regret it
I want to manually flash 4.0.4 and stay unrooted. Should I use the GNex Toolkit to flash 4.0.4 directly or do I need to flash the same version I have on my phone?
Sent from my Galaxy Nexus using Tapatalk
I had the same issue described by the OP, the belly up android when trying to update to 4.0.4 from the OTA notification. I had previously changed to 4.0.2 yakju using efrant's instructions from the first post in this thread: http://forum.xda-developers.com/showthread.php?t=1391881
However, I had skipped the optional sections. In particular step 12 to flash the recovery partition. I went back and just executed step 12 (fastboot flash recovery recovery.img) and rebooted. Then I was able to update to 4.0.4 successfully from the OTA notification.
I'm guessing I didn't have the "stock recovery" because I previously had the default Samsung version?
Just got the update again OTA, and again the belly up droid. I'm really pissed now, bc it also reset my Go launcher... Had 7 screens w/ widgets and shortcuts...
Why did it go wrong again? I thought I put back the recovery to stock to solve the OTA problem... Should I do other things? The phone starts to really slow down and I'm ready to toss this piece of c* in the bin...

I had the same issue just now with my phone (unlocked, rooted, stock revcovery), but a quick reboot allowed the update to complete and I'm now on 4.0.4. Did you check the version number again after this latest attempt?
Yes, still 4.0.2.
And of course, my phone says I'm up to date. Lovely, NAAAAAT!

OTA

So I know the rule about never accepting otas but I was asked a question and couldn't remember. So if I accept an ota will it brick my phone or will it just update and unroot?
Sent from my Galaxy Nexus using xda premium
depends on what you did to your phone with root access.
are you on stock? ROM?
Yea stock rom just rooted
Sent from my Galaxy Nexus using xda premium
Well if you are on stock and you rooted, you will most likely lose your root (although some posts around here say that root aces is preserved during update in some rare cases).
If you are on a custom rom (e.g. if you installed an update using a custom recovery) and you are updating to a stock update then you will be likely screwing your phones system. depending on where you messed (or let a programmer mess using custom recovery or Rom managers) you could be bricking your phone as well since there are updates for boot and recovery in the stock updates to 4.0.2 and 4.0.4 (I don't count 4.0.3 since google pulled it off their site).
If you want a stock version of the newest android for your GN make it a manual patch by following this guide http://forum.xda-developers.com/showthread.php?t=1391881 make sure you do flash the boot, recovery and radio as well...
But before you do that check in with the forum thread or website were you got your custom rom or root method and ask them for advice, Yeah do that! It's the safest way to do something when you know how others got to the point where you wanna go!
Thx alot

Please let us know how things worked out for you.
Hint: after following the steps above you are on the official google builds. Nice thing about that is you get new android versions as updates on the very second they are released. And most things that come with root are already available in the unrooted system (except overclocking) so why bother about root and stuff when you as a non-developing user can acces more priveleges on stock while rom builders for other phones try to keep up with YOUR system?

I'm completely stock right now just a rooted 4.0.2 I will probably stay like this until cm9 becomes stable or AokP next milestone comes out because he current one did not agree with my phone at all

If you still have CWM installed, then just download this and flash it in CWM. Done.

4.3.1 rooted, how to go to 4.4.2 ?

Hi dudes,
I've got a used Nexus 7 (2013) on android 4.3.1 firmware but rooted ...
I'd like to go to the lastest firmware 4.4.2 I guess, so I wonder if I can do a upgrade using the wifi as an unrooted tab or not ?
My tab is rooted , is it a problem for upgrading ?
If so, I'd rather unroot it, I prefere tablet as brand new ...
is there a way to brick my tab using the official update (by wifi) ?
Thanks !
If you are not receiving the update, just unroot it, and return it to stock. You can use the Nexus Root Toolkit by Wugfresh. It's really simple to use, and the help section is really good. Goggle it.
Have you tried going into settings, and going into system updates? Just having the tablet rooted, should not prevent you from receiving updates. Now, if it's routed with a custom rom, that's a different story. Good luck
--=={BSnapp} ==--
hi, it is rooted with the official firmware 4.3.1 I Guess( is there a way to see if it's a custom or official firmware ?)
and I've got the notification of the 4.4.2 upgrade ...
?
In parameters here is what I've got :
band base version
DEB-G00_2.25.1_0802
kernel version
3.4.0-g9e52a21
[email protected]$1
so official one ?
I see that you have the LTE model (DEB.). If you could post a screenshot of your About Tablet screen, one of us should be able to help you.

apparently, trying to do a recevory using the POWER and UP trick, it seemes the guy before me has installed clockworkmod recovery v6.0.4.4 so what should I do ?
You could flash a 4.4.2 ROM using Clockwork Mod recovery. NOTE: Please research and double check every step before flashing. The basics are: make sure that you have plenty of battery life; make a backup of your current ROM; do a factory reset in Clockwork Mod; select a 4.4.2 specific to your device, e.g., Paranoid Android for DEB; download a zip file of SuperSu 1.94; download Gapps; then flash the ROM, Gapps, & Supersu. Again: read, read, read through XDA before flashing anything. EDIT: Make sure that you have the most recent Clockwork Mod version for your device.

I understand only English, so I don't know. I do know that as Bsnapp's post states, Wug's Nexus Toolkit works well for unrooting and flashing stock. Back up your files first.
