when we see acer subscribe to Open Handset Alliance and we have no usable source code and now locked bootloader, we can doubt in efficiency of this label ... it's a joke.

update

acer a1-810's fw has updated to ACER_A1-810_AV052.RV21RC02_WW_GEN1. It's 76 mb update but I can't update and I can't unroot via toolkit. Stucked.
[Miscellaneous Android Development] EQUANCY:
I'm glad to hear you've signed our purpose.

As far as I know OHA is not relevant with locked booloaders and there is no obligation about SDK sharing.

OHA determines only Certain Standarts of an Android based devices and also partially source code sharing.

On the otherside, ACER using kinda AOSP based Android, which means it has already contains open source codes,drivers etc. (May be I could know that wrong, not sure) but ACER is not publishing its SDKs.

After all, thanks again.

Firmware Update

Hey i just installed the RV21RC02_WW_GEN1 on my A1-810 and now i can't use your toolkit so can you please add a new version?

And one more thing after installing the update my battery indicator goes maximum to 76%. I charged it for 10 hours and the problem is not solved. Also i rebooted it several times but that didn't work too. If you have any solution please contact me. Thanks!
[Miscellaneous Android Development] entonjackson:
what does that mean "you cannot use"?

if there's no system.img.gz for the new firmware then create one, or wait until someone provides it. i cannot change this as i don't own an a1-810...

UPDATE

I confirm an update from Acer that cannot be applied with my Acer A1-810, root ver. RV18RC07_WW_GEN1.

This update weights 76MB.

This is exactly what I've done:

I remove the root from unchecking the box in the settings of SuperSu. The "su" binary is kept by Voodoo OTA Keeper, a modified version for A1-810 that SODAFR75 gave me.

I go to the "About" section, in the settings, I touch the "update" button. Android tells me there is an update, which corrects the battery indicator. I click on "Download".

Then the update is downloaded in a ZIP file, in /cache/fota_dn/. Well, I'm root, so I copy the ZIP file to my computer, in order to save it.

Android asks me to reboot, in order to install the update. I say "Yes".

The A1 reboots. It tries to install the update, then shows a superb "Error !". I cannot do anything; The only thing I can do is pushing the Reset button with a needle: the A1 shut down. I press the Power button, the A1 switches on, everything is normal. When it has booted, I only have a message from Android: "The update cannot be done". That's all folks.

Here is the update file (ZIP file, 76MB). It comes from my personal dropbox, so I will delete it one day or the other (but not tomorrow, maybe in two-three weeks...). So please, downlaod it then re-upload it where you want.

Just CLICK THERE.

I hope that my English wasn't too bad and that you understood everything.
[Miscellaneous Android Development] entonjackson:
Thanks for the valuable info.

Downloading the update.zip. will provide it on page 1.

What is the exact version of this update?

Maybe Acer built in some kind of root recognition and in order of root blocking updates. I don't know why the f... they should do that, but who knows.
[Miscellaneous Android Development] yatto:
The exact version of this update ? Uuuh, I don't know, because I cannot install it !

I'm asking it on a thread on another forum, I will edit this post when I know it.

Another hypothesis is that, since I have uninstalled some crappy apps (the antivirus, Astro, Games HD, etc.), the update cannot find them and refuse to apply itself. I don't know, I just tell you what I've done on my device (and since I rooted my A1, things just went really well, no problem :) )

EDIT_1: By the way, I signed the petition for unlocking Bootloaders for Acer Iconia devices, and I also sent the e-mail with the template you've made for Acer.

EDIT_2: The update is referred as "1.105.00 WW GEN1". I don't have more information, at the moment.
[Miscellaneous Android Development] nribeiro:
So what can I do to root my Acer A1-810? Just Install a stock image from the 1st post and then the rooted one?
[Miscellaneous Android Development] yatto:
More information about the "battery indicator" update:

So the new version is Acer_AV052_A1-810_RV21RC02_WW_GEN1.

And curiously, this is exactly the same build that my neighbour upside me "nribeiro" is talking about. So, for the moment, just wait and see.

Maybe,

and I am NOT a specialist so MAYBE

you can install on your device the old rooted Android image(so you will lose the benefits of the recent update, the battery indicator is more efficient and NTFS is natively supported). or

MAYBE you can try

to root you A1-810 manually from Linux. AND MAYBE doing as I say here can BRICK YOUR DEVICE so...

I recommend to wait for Entonjackon's answer.
[Miscellaneous Android Development] nribeiro:
It's the same as mine. Maybe I'll wait or not...

So wich roms are rooted? They are in the 1st post right?

Best regards and thanks for the help.

B1-710 cannot swap internal and external

Hi

I have tried to swap internal and external SD with the toolkit after rooting my Acer Iconia B1-710.

It seems to work at first... in Root Explorer I can see that the vold.fstab has been changed. (the 1's have changes to 0's and 0's have changed to 1's like they are supposed to)

But when I reboot the B1-710 there is now only an internal SD. The external one is gone. It does not come back until I change the vold.fstab back to its original state.

I have been trying to play around with the numbers and the emmc@fat/auto values. But to no avail. Either only the internal SD is shown or both are shown - but not swapped.

Should the external SD be formatted in a special way to work as internal? Right now it is standard FAT32.

Or does the vold.fstab.nand file do something about this? In this file only the internal SD is mentioned.

Hope somebody can help. Thanks
[Miscellaneous Android Development] entonjackson:
I doubt the root from scratch method under linux will brick your device, because the only thing it does is pulling your /system partition, adding the su binary and pushing it back to your tablet again. The only problem here is, that the a1-810 needs different su binary and config than the other devices, so you won't have RW permissions for mounting /system partition.
[Miscellaneous Android Development] entonjackson:
Could you please try this and give me feedback, it worked or not.
[Miscellaneous Android Development] ssamsonice:
Thanks.

I tried editing the vold.fstab.nand as well. But it the post you are referring to is not quite exact on how to edit that file, so I gave it a few shots.

The original line in the vold.fstab.nand is:

dev_mount sdcard /storage/sdcard0 auto /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.1/mmc_host

And the original lines in the vold.fstab is:

dev_mount sdcard /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.0/mmc_host

dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.1/mmc_host

With both the original lines in place in the two files I have an internal memory (5,5 GB) and an External SD (29,71 GB)

I then made changes to vold.fstab to look like this:

dev_mount sdcard /storage/sdcard1 emmc@fat /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.0/mmc_host

dev_mount sdcard2 /storage/sdcard0 auto /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.1/mmc_host

just like the toolkit does.

Now for the changes to the vold.fstab.nand:

In my first shot I tried just to edit the 0's to 1's like this:

dev_mount sdcard /storage/sdcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.1/mmc_host

After a reboot I only had the internal memory (with 5,5 GB)

In my second shot I copied the lines form vold.fstab to the vold.fstab.nand and erased the original line in vold.fstab.nand. Now the two files are identical like this:

dev_mount sdcard /storage/sdcard1 emmc@fat /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.0/mmc_host

dev_mount sdcard2 /storage/sdcard0 auto /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.1/mmc_host

But the same result as above: Only internal memory (with 5,5 GB).

So do you know what I should be changing in the vold.fstab.nand?
[Miscellaneous Android Development] entonjackson:
take a look at this
[Miscellaneous Android Development] ssamsonice:
The suggestion in these posts is what I have been doing.

The exact text in the swapped-textfile is what I have been using for vold.fstab.nand.

But is there a certain way vold.fstab will have to be as to not conflict with vold.fstab.nand?

I have tried many things - like completely commenting out the vold.fstab and using original and swapped texts - but every time the external SD is not there. Only when I use the original texts in both system files will my 32 GB SD card show - but sadly not as internal memory.

Hey guys,

I don't know if i'm right here, but it would be really nice if one of you could tell me if it is possible to flash an older version of the firmware on the acer iconia a1-810 using the stock recovery tool. yesterday I accidentally updated my firmware and now i wonder if theres a way to get back to the previous version. I tried searching the Internet and also these forums but couldn't find any usefull information.

I really hope you can hell me and sry for my bad english but it is not my native language.

Rooted A1-811 Successfully

Hi everyone

I have a A1-811 and successfully ROOTED it. I used the "A1-810 ->Root from scratch" method without any problem. Please adds A1-811 supports to the Toolkit, thanks.

By the way, I tried to use my rooted .gz directly root my device, but no luck. It fails when checking firmware version. After that, I changed something in .toolkit.py(l.split("Acer_AV052_A1-810_")[1].split("_WW_GEN1")====>l.split("Acer_AV052_A1-811_")[1].split("_TWN_GEN1"))

I replaced A1-810 with A1-811(Cause I have a A1-811), and "_WW_GEN1" with "_TWN_GEN1"(Cause I have a Taiwan version). I tried them both under WINDOWS and LUBUNTU. It only worked with Lubuntu but not Windows(which was still failed when checking firmware version). Lubuntu operated the whole things well.

I am not professional, please don't easily try this method until the official Iconia Toolkit updates!!!! If you try it, I don't pay any responsibility to your A1-811

Here's my rooted system.img.gz for A1-811 Taiwan version on Google Drive docs.google.com/file/d/0Bz5DDMjsS0KMcXJyR25lOGdLYWs/edit?usp=sharing

Developers, please check it out and help me with it if there's any problem, thank you.

Hello developers,

I have a question to ask. I'm currently using Koush's(Clockworkmod) superuser, everything is fine. I can gain root access by using root checker and other APPs(such as Adaway, RAM manager, etc.) But I couldn't update my su file with the superuser app. Would you please help me with it? Thanks a lot:D

Apply Root

Hi. Just purchased my a1-810 and wish to root.

I guess I just apply the update.zip within the stock recovery and all sorted? No need for adb or windows?
[Miscellaneous Android Development] shantusingh:
Just wanna share rom toolbox and any other cpu app is no good, the best and best app for stable 1.2 ghz cpu overclocking is " System Tuner " . Rom toolbox has only option to overclock after reboot and until we are using till screen in on, but of course after using tab for sometime then we put to standby and once we use back again then the overclocking goes off and comes back to 1001 ghz . But in system tuner, after we turn back on from standby it instantly takes root permission and is always on 1.2 ghz ( I check by using standard quadrant system information and current frequency changes there, so now it always remains on 1.2 ghz whenever I check and has improved speed a lot ) . Just wish we get 4.2.2 atleast on acer b1-a71 as more ram will be available and games can load faster and be played normally even if acer b1 has less benchmark in fps .

I just have one doubt as 1.2 ghz comes and remains fixed only on "hybrid" settings, so I read somewhere that by hybrid, 1 cpu takes full cpu usage for example 1.2 ghz and other (if dual core) goes to sleep, but I don't think this is happening as speed is really improved even in games ... so I still believe both cores work on 1.2 ghz when required like while playing games, etc .

Hello,

I have an Acer Iconia A1-810 since August and I really want to root it. I'm downloading the system.img.cz file but the download speed is very very low (about 37,5kb/sec) this is not normal, normally I make downloads at a average speed of 600kb/sec.

If I flash the system.img.cz file with the Acer Iconia toolkit, will it erase all my data?

Thanks,

Too tired or just scared of doing wrong

Hi!

Maybe I'm to tired for this, but I need help in rooting my Iconia A1-810.

I have just updated standard firmware to the RV21RC02_WW_GEN1. I've downloaded the toolkit AND the newly added update.zip (for RV21RC02_WW_GEN1). But when I read the README and toolkit-folders it says I should add a system.img.gz in the image directory, not the update.zip. What is the system.img.gz that I should use.... and what is the update.zip file for ?

Sorry for the inconvenience.... but there are to many files for my brain right now...

Thanks!

Marcus
[Miscellaneous Android Development] entonjackson:
There won't be a system.img.gz until someone roots his A1-810 with "root from scratch" method. But this method works only under Linux.

As there are thousands of free Linux distros anyone could do it from a Linux installation, vm or live cd.

After applying root from scratch with my toolkit, there will be a rooted system.img.gz in /cache folder.

Ok, Thanks! Looking forward to it.... hopefully some firendly Linux-user will help us out. :o

this the installation instructions of the ROM of sebasrock156 :

What's up... I will explain how to install the ROM manually... is somewhat boring but here goes... remember that to this tablet should be your root

Should not pass it Here: http://www.madboxpc.com/foro/topic/181890-actualizada-rooteo-tablet-acer-iconia-b1-a71/

Now let:

With Root Explorer and Root Explorer just go to the path / system and copy the corresponding traditionally files in each folder:

In App: All files must be in permissions rw-r - r - or as we know other inverted L

(Cap in the post)

In Bin: All files must be in permissions rxwr-xr-x

(Cap in the post)

In Etc: The relevant files should have the permissions to rw-r - r - and the folders in rxwr-xr-x

(Caps in post)

In Framework: All files with permissions rw-r - r -

Note: Framework-res.apk file you change the permissions to rw-r - r - outside the Framework folder and then copy it

(Caps in post)

In lib: All files with permissions rw-r - r - and folder permissions soundfx rxwr-xr-x

In Usr: All files with permissions rw-r - r - and folder permissions Share and xt9 rxwr-xr-x

In Vendor: All files with permissions rw-r - r - and folder permissions Etc rxwr-xr-x

Before asking all files within the folders also permits you must put ¬¬

After all that editing your build.prop (cap in the post) and pasting the following lines:

# # # SONY Media Applications Properties By Rizal Lovins # # #

# Mobile Bravia Engine 2

ro.service.swiqi2.supported = true

persist.service.swiqi2.enable = 1

# Sony Clear Audio +

Hey dude.

I am also a newbie here like you and faced few problems too.

First of all , check whether your firmware is AV051.B1-A71.RV05RC05.WW.GEN1 ( you can check that in the settings>about tablet : Image version.

Follow the steps very carefully and dont even do like touching the tablet when the toolkit asks you not to.

You could try put the RV21RC02_WW_GEN1: update.zip on your sd card and follow the FAQ:

A1: The system.img.gz you applied, wasn't suiting to the firmware version installed on your tablet. Download latest Acer firmware update, copy it on a micro sd card, plug it into your Iconia, go to recovery by holding Volume up and Power button while device is turned off. Then choose apply update from sd card.

Who knows might work, can't get worse right? :)

Thanks for sharing the image. I can't use it though I believe it will be useful for others. I'm having A1-811 and already rooted it by using Root from scratch of A1-810. By the way, the root from prerooted system.img.gz method won't work for A1-811 yet, I think something must be changed in .toolkit.py.
