Hi,

I have an Acer A1-810 tablet (16gb) running Android 4.2.2

What is the latest version of Android available for this tablet?

I found a copy 4.4 from the thread but I keep finding references to a new lollipop rom (but most of the links I find require me to 'fill out a survey' before I can download... BS).
[Android General] nikagl:
It depends on your SKU (PA_CA, PA_CUS1, WW_GEN1, EMEA_FR). Latest for WW_GEN1 is AV0K0_RV0HRC03 which is Kitkat (4.4) and also mentioned in the firstpage:

SD card (recovery) update zip:

A1-810 [KK] SDs_Acer_AV0K0_A1-810_RV0HRC03_WW_GEN1.zip

SPFT firmware:

A1-810 | KK | http://is.gd/f810_44 | 640b0a19247b449b4dd166e050ccc01b | AV0K0_A1-810_RV0HRC03_WW_GEN1

Acer A3 20 FHD Formated

Hello,

the best possibility for me with the acer a3 20 fhd turtorial is to use the 5.1532 Flash Tool and to delete the checksum.ini file from the firmware files. With this method i can flash the whole rom and the flashing process ends with a green circle, but the tablet makes no noise or still boots up. Perhaps because of the deleted checksum.ini file?

When I'm using the 5.1532 Flash Tool and with no deleted checksum.ini, I'l get the Brom Error 4008 (Pic)

[IMG="Flash Process"]http://www.fotos-hochladen.net/uploads/flashwithchecj7kqm4yrhu.jpg[/IMG]

Perhaps someone knows what to do and if the missing checksum.ini is the reason, why the tablet still not starts, or someone could help me with the Flash Process after reading the log file.

Best regards,

Peter

Hey guys, I am currently searching a way to Root one of the newest Acer Tablets.

Unfortunately there is no known way to get Root access for me.

I already tried Kingroot, Kingoroot without success.

Now I wont to try out to unlock the bootloader and get a cfw.

I hoped you guys could help me out with it.

It would be really great if so.

Driver installation

Hello,

what about installing the drivers for the tablet by hand in the device manager? Right click on your device "update drivers", then "seach on the local PC for drivers", then "choose drivers from a list on the PC", then click on "data storage device" and finaly select the "android_winusb" from the extracted zip file from the link below. Click "ok", next uncheck "show compatible hardware" and then try out some of the drivers.

Actual MTK Drivers:

MTK_Drivers 1.6 (Google Drive Link)

Peter
[Android General] Darrian:
I used the drivers from the Acer site. They will work. You have to disable driver signing enforcement as per the instructions that come with the drivers and reboot. If they said to disable UAC then I did that, too. I remember I was thinking something wasn't a necessary step but eventually I did it anyway and it worked, so it was probably UAC. As an aside, I never did get the camera working, and when I finally sent the tablet in for repair of a cracked screen they couldn't fix it (they were trying to fix the camera, too, even though I told them it wasn't a necessity) and instead I got store credit to buy another tablet, so I got the latest model that comes with Lollipop. I'm probably not going to try rooting that one.

These may be the same drivers you already downloaded. Nevertheless http://global-download.acer.com/GDFiles/Driver/USB/USB_Acer_1.0_A44K_A.zip?acerid=635587051048782537&Step1=TABLET&Step2=ICONIA%20TAB%208&Step3=A1-850&OS=ALL&LC=en&BC=ACER&SC=PA_6

I also just remembered I had to go into device manager, uninstall the device as it was installed, and reinstall it choosing my own driver, choosing the ones I downloaded from the Acer website instead of what was automatically installed.

Beyond this I can't help you. I no longer have that model, I deleted the drivers, and it has been too long for me to remember perfectly now. I hope this helps and wish you luck if you truly want to continue down this path. I can't warn you strongly enough that if you care about having a functional camera this may break it for good.

A1-811 CWM

Rooted A1-811, waiting for kernel 4.4 sources for RW /system
[Android General] spljaa:
Thanks, that disable recovery flash was the trick I missed. I mean I did not boot to CWM first thing after flash...

What is the problem with su provided by that CWM? Does Android 4.4 has other security enhancements that stop it from working? some kind of selinux?

Many thanks to all who helped me get that far.

[Android General] Moriveon:
With root by CWM you can't RW /system.

To fix it, we need kernel 4.4 sources, waiting for Acer now.
[Android General] spljaa:
Hi,

In my case I feel like the

su -

command in terminal does not work at all.

Usually after su, when I execute

id

then it at least show me I'm root. It might be that due to some kernel settings even root can't do some things, like remount. Still on my A1-811 device I think it is not root at all.

Other example: usually su gives new shell, thus after su, an exit command will return to original shell. In my case it exits terminal...

I have no idea how to try to help you with fixing it. Probably I will try to search a bit. All recommended sources and guides are mostly welcomed.

And most likely you are totally right that some changes in kernel might be needed, to ensure some polices are less strict.

Change su on A1-811

Link on page http://www.android-hilfe.de/root-cu...er-entsperren-cwm-installieren-kk4-4-2-a.html points to supersu.

And it worked for me.

One trick is to upload it to device.

./adb sideload update.zip

was some option, as CWM for A1-811 can't mount sdcard, yet.

It might not be full root. However it works for Titanium Backup. I plan to see if it is sufficient for AdBlock

It opens a question:

How to write own update.zip files? For example I would like to upload some keyboard mapping to device.

In CWM one can access /system. Which is otherwise ro if I understand correctly.

Or maybe there is option to download such image, and play with it the way root-toolkit does? And then upload it using CWM...?

Hi Nika. I tried to flash your ZIP file on my Acer B1-750. My tablet shows exactly that file title as its Image Version in its "About Tablet" status page, so I had great hopes.

Unfortunately, the process stops with an error, before it completes:

Do you have any hints?

I'm not sure were you got that file, because I couldn't find it on the Acer website.

I was trying to do this because after rooting, I screwed up the camera by removing the Google Pinyin Keyboard. There was some comment that this would happen if you delete the Korean keyboard, but apparently removing the Pinyin keyboard also creates this problem:
[Android General] nikagl:
Hmmmm... end of footer error sounds to me the file you downloaded might have been corrupt? With which recovery are you trying to flash this ROM? How did you root it, and can you try to use the recovery stock and/or the one you used to root the device?
[Android General] limited_imagination:
Hi, thanks for the reply.

I used the stock recovery, and entered it by starting with the power off, then holding power button and the volume up together, and then it gives me the option "apply update from external storage". I then navigated to your ZIP file on the external SD card, and selected it for installation. That's when the error, above, shows up.

I rooted the tablet with the "Fastboot Tethered Recovery Launcher", as described in that thread linked to the paraiso-san quote, above. That does not give me the option of installing a ROM from an SD card, although it does allow a "install zip" option in the menu. During the root process, that option installs the SU UPDATE.ZIP, so I don't think that should be used to try to install your ROM zip file, but you could set me straight there if I am in error.

I tried a wipe data/factory reset from both FTRL and the stock recovery, and interestingly I still get "Camera cannot connect" error. The paraiso-san quote is pretty clear that a re-install of the ROM is the only thing that will work.
[Android General] Shreps:
If you're Root, you can try to extract missing APK from the ZIP, and push them to your system. Or you can also install keyboards from Google Play Store.

Envoyé de mon One+
[Android General] nikagl:
Right, good suggestion by [MENTION=4493088]Shreps[/MENTION] for trying to add the APK manually. Additionally, please confirm that you are sure that the download was successful, as it installed fine for others...
[Android General] limited_imagination:
Hi, thanks for the suggestion.

I have already tried this, and in fact I had already backed everything up with Titanium Backup before fooling around, and so I re-installed the Pinyin keyboard from Titanium Backup.

Re-installation of the Pinyin keyboard APK has no effect on the camera problem.

From reading the comments in that other thread, I think that the problem is not with the APK itself, but it arises instead from something else in the factory ROM that depended on the original installation of that keyboard.

That's why I'd like to flash the entire stock ROM again.

Interesting that other people have not had trouble installing that ZIP file. I have downloaded it three different times, and tried to flash with each separate download. No joy, same error each time.

The contents of the ZIP file do not look corrupt when I view their folders on my Win7 PC. It all looks good inside.

Would it be worth trying to use my Win7 PC to create a fresh ZIP file, with the same title, from the un-ZIPPED contents of that file? Or is there some kind of signature check that would be defeated?

I wish I knew what the error "not 0xFFFF (File exists)" means. Google searching that phrase is not much helping me for that.

I installed a terminal app on the Acer, and ran "dmesg" to see if the camera driver was even being loaded. But neither the word "camera" nor "cam" show up anywhere in the dmesg output. If anyone else with a working camera feels like looking at their dmesg output to check how the camera driver loads, I would be curious how it's supposed to look.
[Android General] nikagl:
Creating a fresh zip should work, except not with stock recovery (which expects it to be signed). So when you use custom (CWM) recovery it should install too. I have searched for the 0xfff error too, but nothing concrete either. It did occur for some other Acer users, but all on other devices... and some Zenfone users... that's all.
[Android General] limited_imagination:
Ok, the CWM recovery I used to root the device, starts up Vampirefo Venue 8 v.6.0.3.7, just like in this thread: http://xdaforums.com/dell-venue/general/successfully-rooted-android-4-4-4-dell-t3166706

Once I chose CWM at that stage, it starts Vampirefo Venue 8, v.6.0.3.7. I never get a menu option to "install a ROM" or similar, like I do in the stock recovery. I only get an option to "Install update from zip file", where I can navigate to the SD card and select your ZIP if I want. It comes in the second menu item under this screen:

I am worried that if I navigate to the SDs_Acer_AV0K0_B1-750_RV03RC02_WW_GEN1.zip file from this menu, that Vampirefo Venue 8 will not install it in the same way a full ROM should be installed by the stock recovery. This is the menu option I previously used to install the SU update.zip file, as mentioned in all the rooting guides, but that's as far as my experience with it goes.

Can you comment on this? If I can install the ROM ZIP from this menu option, then I might as well try your own ZIP from here, before I create a fresh zip.
[Android General] nikagl:
You can surely install the ROM with either the CWM (Vampirefo) or with the stock recovery. Difference is that CWM doesn't require signed zips. Assuming that the CWM is created for this device, and the fact it already worked for the SuperSU update.zip you used to root the device, I doubt it would be a problem running it. Although... having said that... I don't have the device so I can't talk from experience here - you'd have to rely on comments from other B1-750 users to know for sure what to do... (although I doubt they'll respond as I seem to be one of the few consistently responding to this thread)
[Android General] limited_imagination:
In the interests of science, I went ahead with it.

It worked!

Now I have my camera back, along with all the other Acer bloatware.

I have lost root of course, but that's going to be easy to get back again I think.

And now I know to avoid removing both the Pinyin and Korean keyboards.

Thank you for your encouragement, it's a little nervewracking to get up to the "This cannot be undone" warning in Vampirefo Venue 8, when nobody has had 1st hand experience with that.

No idea why the stock recovery would not flash this ROM on my device, but Vampirefo Venue 8 did the trick with the SDs_Acer_AV0K0_B1-750_RV03RC02_WW_GEN1.zip file.

edit: just for curiosity, once rooted, I checked the dmesg output, and the camera entries show as follows:

<6>[ 33.814796] gc0310 2-0021: camera pdata: port: 0 lanes: 1 order: 00000000

So, I have tried to install a custom recovery of this topic (recovery_PhilZ.img) on my b1-a71, and have flash with the Flashify. In the moment that I have restart my tablet, I went immediately on the bootloader and try to go on the custom recovery, but after the Acer logo, screen turns black and then, the tablet is turned off. I don't know what to do, pleeease, can somebody help me?
[Android General] limited_imagination:
So I was really curious why this device was supposed to come with 8 GB internal memory, but both ES File Explorer and also the Android's built-in System -- Storage graph, showed only 3.66 GB were available to the user.

The System -- Storage graph showed 4.26 GB allocated to "System", which seemed brutally wasteful.

I ran an app called Storage Space, by Lakshman, available on Google Play, to get an idea of how this thing is partitioned, and it seems pretty wasteful to me.

Of the 8 GB on board, this thing only has 7.04 GB partitioned to be used for anything. So right off the bat, about 0.96 GB is wasted as completely unused.

The Block 15 partition, "/data", has been partitioned to 3.66 GB, which is the only storage area permitted for user-installed files.

Of the rest of the 8 GB, the Block 14 partition, "/system", is allocated 1.94 GB, of which only 1.12 GB is used (0.82 GB unused).

The Block 12 partition, "/cache", is allocated 1.16 GB, and was currently 100% unused. I had just cleared my cache before running the app, but it seemed to me that carious apps creating cache files would create them in the /data partition, since that's what shrinks the available 3.66 GB over time. Google Chrome is the worst offender in this respect. So I have no idea how the device uses the Block 12 partition.

The rest of the Blocks are partitioned into smaller spaces of 64 MB, 32 MB, 16 MB and 12 MB, but even these partitions are wastefully used to my eye. Block 11, "/config", for example, only uses 84 KB of a 12 MB partition. Block 9, "/factory", only uses 44 KB of 12 MB partition.

It looks like it should be possible to re-claim at least another 2 GB, or roughly another 55% of the storage space allocated to the user under Block 15, "the /data" partition.

Has anyone tried to re-partition their Acer?

Is it even possible without an unlocked boot loader, like this B1 - 750 device has?
[Android General] RuthieRayne:

Ok...so for some reason my computer doesn't recognize the device. I've downloaded drivers, both from the source listed and from another source.

When I turn the tablet on and look in the device manager, I see the error "this device cannot start. (code 10)." This is the same on my Windows 10 computer and my old XP computer. Nothing seems to work. Anyone have any thoughts?
