Thanks for the really fast reply!

Hmmm.... two questions:

Have you specifically heard about one of those two apps causing bricking? Alternatively, do you or anyone know about someone hiding the bottom bar successfully after rooting an A1-810?

If I try it and it bricks it, how likely am I to be able to restore it to the way it was using the saved stock system image?

Thanks!

[Miscellaneous Android Development] entonjackson:
1. not exactly that app. mainly it was about changing DPI

2. if you get into a bootloop, the only thing that will help you is getting into ADB over META Mode. There are some guys here, having good experience with META mode, me excluded, i never needed to get there.
[Miscellaneous Android Development] Optimissimus99:
If you really just want to get the full screen mode, install the KitKat Update I you have the Immersive mode. If you don't want KitKat, I really recommend you to at least upgrade to RV27RC03

(not rv31, this version and up breaks root)

Hi to all...is there any way to downgrade my acer iconia a1-810 from kitkat (4.4.2)? I have some sound problems...please help...thx a lot ☺
[Miscellaneous Android Development] Moriveon:
I looking for the way to do it, I'm just need to find somebody with 4.2.
[Miscellaneous Android Development] Optimissimus99:
As Acer said in the update message, you can't downgrade anymore. (I think when you try to flash JB with the recovery, it fails, at least someone at android-hilfe.de tried it and failed this way. ) Also you can't use system image trick anymore on KK ( Acer disabled it + u would need the old kernel.) Try to fullwipe it, maybe this helps, but u can't downgrade ;) wich version are you using, I have ww gen1 and all seems to work great.(and +2000 AnTuTu Score)
[Miscellaneous Android Development] Moriveon:
But there's a way to downgrade. With SP Flash Tool.

I've found the man with 4.4.2 - he can test.

But I still need for somebody with 4.2 (if you do not mind your tablet, pm me) to experiment.
[Miscellaneous Android Development] Optimissimus99:
Sorry I am already on KK
[Miscellaneous Android Development] DustArma:
Changing DPI won't cause bricking, however too low of a DPI will trigger Tablet UI mode which will cause System UI to constantly crash as it's missing the Tablet UI resources, this can easily be fixed by flashing the stock firmware over in recovery mode or by just trying to change the DPI back during the system UI crashes.
[Miscellaneous Android Development] Fekijevac:
I have the same version?.can you try to connect headphones and listen one song?

---------- Post added at 12:38 AM ---------- Previous post was at 12:21 AM ----------

I don't understand too much in flashing android etc. But i think that on official acer web site you can download 4.2 image..
[Miscellaneous Android Development] entonjackson:
I know people definitely reported about bootlooping devices after changing dpi.
[Miscellaneous Android Development] Moriveon:
I have found very interesting Acer Site. It's only for Acer employees.

"...who are authorized to have access to more in-depth technical service information"-Sign Up page.

I tried to sign up with fake info, but Acer is checking my info now:(

Update #0

- Terms of Service.

Hmm, if I'll wait for few days, maybe I can get access to website.
[Miscellaneous Android Development] yoshm:
Thanks, [MENTION=5737085]Optimissimus99[/MENTION]. I have looked and do not find an upgrade from Acer for KitKat - can you tell me the link?

Also, I am wondering

@Fekijevac reported a sound problem with KitKat - anyone else experiencing that?

If I save the the current img using the Toolkit, won't I be able to downgrade by reinstalling that (despite what you reported that Acer says impossible to downgrade)?

B1-720

Well, thanks to you good folks, I got my B1-720 rooted. Anyway, I need a little advice. Now that I'm rooted, do you know whether is it safe to install xposed? I'm afraid to get into a bootloop as I have no idea how get this device out of one.
[Miscellaneous Android Development] Optimissimus99:
i think its really impossible to Downgrade, but maybe someone will find the way to do it. To upgrade to KitKat you first need the last JB (RV27) wich can be Downloaded via Acer support site. Then there will be two Updates, one RV31 JB and the second with KK.

[MENTION=1992318]Fekijevac[/MENTION]

I've connected my headphones and played some Games, wich worked fine. I have no mp3s on it but I think this will also work

And yes, XPosed should work fine, and if there is a Loop caused by it, it can be resolved by factory reset
[Miscellaneous Android Development] ivoda:
After usage of kitkat about 10 days on A1-810, my impressions are:

-battery life is almost good as it was on 4.2,

-really good response for every task using ART,

-unable to use sd card for write on by preinstalled apps, only as a storage ( movies, music ) - due to kitkat,

-unable to use toolkit anymore - due to ACER,

-no error or bug for now.
[Miscellaneous Android Development] yoshm:
Thanks. My image version is Acer_AV052_A1-810_RV03RC08_WW_GEN1, which I gather is "RV03" not RV27 - correct?

I've looked on the Acer support site & I cannot find a way to get RV27 (or any other Android update) - can you point me to a link where it is?

Also - when I try to connect to Acer's update server using the Settings option - I get a 1004 error ("Update service temporarily unavailable") - so I'm not sure that RV27 would be able to get those two updates, either. Is there a link to where I can get them directly & upgrade to KitKat without going through the built-in upgrade process, which seems to be having trouble connecting to the Acer update server?

Thanks!

[Miscellaneous Android Development] Optimissimus99:
Have you already The pre Update?

Is The KK pre update (RV31RC03) rootable via Toolkit?
[Miscellaneous Android Development] swing4thefence:
Yes. I already took the Preupdate and rooted from scratch with the toolkit.
[Miscellaneous Android Development] Optimissimus99:
Hmm, then you need to fullwipe ;)
[Miscellaneous Android Development] swing4thefence:
Full-wiped.

Now I can't get the toolkit to complete. it stops at "gzip: System.img.gz: Unexpected end of file

E: Couldn't unzip system.img"

Funny thing is after that it acts like it is rooted. So I decided to proceed with Calingo's instructions. I had (before rooting) downloaded the update file so I installed rootkeeper, temp unrooted, and rebooted. then I tried to execute the update. It reboots and gets about halfway and then fails with no reason given. Upon reboot it says update failed and when I try to re-download the update I am back to "there is not enough space for the system update in download cache storage. I tried this cycle twice with no different results the second time...
[Miscellaneous Android Development] cabalio83:
Try to go back to the previous 4.2.2 flashing acer update.zip, I had the pre-kk update installed over root and KK update was failing. I started clean and managed to update straight with no errore.

Then do the root keeper trick.
[Miscellaneous Android Development] yoshm:
Thanks. I found the equivalent page on the English-language site. I see under OS there are several options. Given that my image version is Acer_AV052_A1-810_RV03RC08_WW_GEN1, I assume the right one for me is this:

AV052.RV27RC03.WW.GEN1	450.3 MB	2014/03/30

I'll try & see what happens.

Thanks,

[Miscellaneous Android Development] Optimissimus99:
Yo, this seems to be the right for you. And look at the KitKat root Guide a few posts ago. As you are on JB you can easily Root KK with OTA Rootkeeper...
[Miscellaneous Android Development] derdar:
Is there no way to root 4.4.2 still? I do not want to go back 4.2.2...
[Miscellaneous Android Development] swing4thefence:
So are you saying that when you went back to the previous 4.2.2 you updated directly from there to 4.4? Because when I did it it's still a two-step process for me to update to 4/.4
[Miscellaneous Android Development] cabalio83:
No, I went back one step on JB then i made the two regular updates to get kitkat. I was stuck at pre-kk and couldn't go further.
[Miscellaneous Android Development] swing4thefence:
Are you rooted?

I just tried the sequence for a second time in a row.

Install the last ota before the Preupdate.

factory reset

download preupdate

root

OTArootkeeper hide root

install preupdate

unroot

download KK update

Root

root process errors out with ""Gzip: system.img.gz: unexpected end of file

E: Couldn't unzip system.img" but yet I still have the SU binary.

OtaRootkeeper hide root

Install update

update fails.

Try to re-download update, "there is not enough space in the download cache for the update file"
[Miscellaneous Android Development] cabalio83:
Right now I'm on KK so no root. I was rooted before.... I flashed stock to get rid of root and update to KK.

Sorry for not being too clear.

I nave not seen any way to get back from KK to JB, so for the moment I'm locked in stock KK
[Miscellaneous Android Development] yoshm:
No joy. managed to install the new OS with RV27 with no problems. However, still getting a connection error ("update service unavailable") when trying to update to KK :(

Finally tried calling Acer tech support. They are investigating and are supposed to get back to me tomorrow.

---------- Post added at 11:13 PM ---------- Previous post was at 11:11 PM ----------

Not sure what you mean - I can upgrade to a rooted KK based on my current JB, without going through official Acer channels?
[Miscellaneous Android Development] Optimissimus99:
Take a look at this ;)

Edit: Quote displays wrong, take a look at Post 3407

To get rid of the update error, try to make a factory reset

Can someone with installed Pre - KK update look if the network utility is usable? (Active Button?) Because actually it isn't sure if PreKK / RV 31 is rootable :(
[Miscellaneous Android Development] swing4thefence:
The Run button is active in Pre-Kat. I have rooted Pre-Kat in the past but this time I get a gzip error in linux. Either something's wrong with my Linux build or somehow the system.tar.gz is getting corrupted when the tool pulls it off. I'm updating to Trusty Tahr just in case and then I will try the toolkit again.
[Miscellaneous Android Development] swing4thefence:
Updating Linux didn't help. I went ahead and updated to see if the update was broken too, but without root at all it upgraded me just fine. Now I"m on KK without Root. I can confirm that the following don't root our tablet on KK:

Framaroot

Towelroot

SRS Root

[Miscellaneous Android Development] Just_Another_N00b:
Are we there yet?

Stil have not seen any (Pre-)KK update on my Canuck A1-810. Still getting the infamous 1004 error on my stock (non-rooted, ok, un-rooted) A1-810 of Canadian descent. I already am on 27 (RV27RC02_PA_CA), but not yet on the Pre-KK JB.

Is there anybody in this forum who has been able to get the pre-KK update on their Canadian A1-810? Still doing a daily reset to stock and 2 times a day a factory wipe. "I will enjoy this!"
[Miscellaneous Android Development] kazzxtrismus:
I do have the update to pre-kk and am in Canada with a Canadian A1- 810.. But I've never been rooted... Can you downgrade to an older image?
[Miscellaneous Android Development] Just_Another_N00b:
I am loading the factory Stock image from ACER daily, and doing a factory reset 2 times a day. Overkill, but the only way I feel is certain to not have Acer think it was ever rooted. I did, however, work with some Supercharger stuff, but I reloaded my own pre-rooted system image, thinking that only that part is worked on by Supercharger. If not I might resort to a full format of all partitions and then reloading the Acer stock image.

Only thing is that that might need superuser setup, and/or I haven't the faintest whether that can be done over adb... Does anybody know if (and how) a full reformat is needed?
[Miscellaneous Android Development] swing4thefence:
Yes. you can downgrade back to the Pre-Precat rom by visiting http://us.acer.com/ac/en/US/content/drivers and downloading it. Just make sure you match the last part of the image name to what's on your tablet. All you do is download to an sd card.

power down your tablet.

Hold Volumeup and Power to enter recovery mode.

Select "install update from sd card"

And away you go.

---------- Post added at 01:16 PM ---------- Previous post was at 01:15 PM ----------

I don't understand.... are you sending it back for service? My tablet was rooted and I still got the update notification.
[Miscellaneous Android Development] Just_Another_N00b:
On your story on the first part: Onve on full Stock KK there is no way back...

On the second part: No, not going back for service. Warranty expired quite some time ago, and the tablet is fine, just no KK
[Miscellaneous Android Development] swing4thefence:
Some people are working now on a downgrade method but they need a scatter file. I haven't been successful getting my hands on one yet. You don't need to keep factory resetting..... When they have it ready for your region's device they will provide it. I think they want everyone to upgrade so you will lose Root.

So normally it should work on nearly all ICS/JB devices, for some it won't but the idea may work in a slightly modded version "

I tried Genius Root and it opened an adb restore dialog too but it failed to root.

A3-A10 Upgrade to KK Released Today

So I received the update yesterday for the initial update for the KK version. Like a dumbass I forgot to unroot my tablet first before authorizing the update. Now I am stuck in a boot loop. It looks like I can apply the update manually from the recovery menu but being a new update no one has the file. Is there anyone out there who can download the file and post it for download????? Acer may take forever in getting the files on their site and I really don't want to have this brick sitting around. I am assuming once I have the initial file installed I can continue on to the full KK upgrade.:cyclops:
[Miscellaneous Android Development] swing4thefence:
If you're in a bootloop maybe the update failed and you CAN use the update from the acer website. And if you have a brick, i wouldn't worry. I'm sure Acer will get around to releasing the update.zip in a year or so.
