CAnt' Unbrick my A3-A20 FHD

Hi guys, I have an acer a3-a20fhd tablet and i've rooted it successfully, after some time my google account didn't work so after doing many things like factory resetting my tablet and other stuff delete and add the account i gave up and decided to update the tablet via the OTA update well guess what since it was rooted the recovery refused to flash the update and i got stuck on recovery i have no android system whatsoever. I followed this guide to flash the tablet with SP Flash tool but i can't do it because sp flash tool doesn't do anything when i press download, i did all the steps before this one and every single one of them worked perfectly this one however does not, it doesn't give any error it doesn't show any red or green bar nor a green circle nothing, can someone of you help me out???? Thanks in advance

I checked the below link but dont know which one is correct SPFT for my tablet?

I'm sure that i had installed wrong firmware on it before, so my tablet now is facing continously connected-disconnected problem when connect to PC and cannot use SP Flash Tool at all,

S_BROM_DOWNLOAD_DA_FAIL (0x7D4) appears right after start downloading

Has anyone else sovled this problem?

Thanks,

Any custom roms for b3-a 20? I'm dying to be able to use my 360 controller with my otg cable, keyboards and mice work, storage works and the 360 controller lights up but has no input.

If anyone knows how to activate something within the system so it will work, that'd be great too. I see there is a key configuration file for the 360 controller so I dunno why it's not working.
[Android General] zeb carter:
I'd like to see more love for this tablet with ROMs and recoveries, too.

I have used Kingroot but recently got a OTA notificationfor Acer_AV0L0_B3-A20_3.006.00_WW_GEN1. I tried unrooting, removing Kingroot but the update still fails. Error message says UPDATE.ZIP found something wrong with ""/system/bin/debugger64" has unexpected contents.

Update.zip is not correct

Installation aborted.

Here's the "suggested" solution over Acer's Community forums:

"Same thing happened to me except my tablet kept going into recovery mode and not booting. Tried factory reset but that didn't work. Ended up downloading stock image file from Acer support site then reflashing using my PC and adb side loader. After reboot the update became available again. It looks like it saves to memory card but then can't access the file to install after shutdown. I removed the SD card and downloaded the update and it installed this time from internal memory. "
[Android General] sixty_oz:
Yeah that update isn't marshmallow or peripheral support.
[Android General] sixty_oz:
Ok, so xpad module is needed, anyone have any idea how to install this on the tablet? getting frustrated, I figured, hey cheap and decent tablet, no custom roms, hmmmmmm. Really want controller support for this thing.

I have flashed using SP Flash Tools and then I unlock, install CWM and flash SuperSU 2.46 (A1-810)

If I upgrade SuperSU in Play Store it asks me for update binaries but I can't do it. Anyone could update binaries or use last SuperSU version? I tried to flash 2.48 and 2.76 using CWM but nothing happens.

SuperSU 2.46 works fine but I don't like Play Store reminding me to upgrade it all the time.

By the way, last A1-810 firmware is AV0K0_A1-810_RV0HRC03_WW_GEN1.zip, in some places I've read this one was 4.4.4 but in tablet says it's 4.4.2, I don't know if there is a newer firmware.
[Android General] Trikk-e:
Ummm, I thought root was OK but I'm trying to uninstall some apps with TB and nothing happens, apparently the have been uninstalled but they didn't. Root is not well done.
[Android General] fREAST:
A quick guide to do this:

You need CWM-recovery.

Reboot into recovery, mount /system and /data.

Connect with adb shell from computer.

cd /system/etc
ln -s /data/hosts OR ln -s /data/data/hosts
(doesn't matter what you choose, both of these options are available in AdAway)

Now if you do ls -l /system/etc/hosts it should say something like this:

lrwxrwxrwx 1 root root 11 Sep 21 20:20 /system/etc/hosts -> /data/hosts

Now reboot, open AdAway, go to preferences, and under hosts file, change target hosts file to whatever you choose before.

Done!
[Android General] spljaa:
Yes,

CWM can mount system and data partitions. Then there is access with adb.

One can access shell there.

Plus push/pull files.

I was able to:

Create symlink for AdAway, exactly as fREAST0 proposes

Modify Generic.kcm for my usb keyboard, to have some alt+ combinations

Install busybox

"fix" permissions for SD card, adding media_rw as some web pages suggest

Remove some apps

Meaning I do have more or less same level of customization I had with 4.2. Obviously it will be nice when boot.img without /system protection could be created

Thanks to Acer Devils for opening that path.

A1-811 KK SDCard access

I used the method in this thread to put CWM onto my A1-811 having just updated to KK in order to regain write access to SD Card.

The point I would make is ignore the comments that say there isn't a complete set of files loaded when SP Flash tries to write.

Once in CWM, load a generic ADB (I think it's an HTC set) driver for the device ID, can then mount system, pull the platform.xml, edit it, push it back and reboot (without rooting). This gives me full access to SD under KK. I didn't root as all my other devices are rooted (CM11) and I need this one for the apps that don't require root (ie sky etc). So pretty much all working well a big thanks guys. Only issue is CWM backup doesn't work as SDCard is renamed, if I sort a fix I'll post it.:good:
[Android General] Mart5:
ADB

What's the code you used to pull and push platform.xml in adb?
[Android General] SluggoAndroid:
Straight ADB from windows command shell

adb pull /system/etc/permissions/platform.xml c:\crap\platform.xml

then edit file to change permissions, then to push it back

adb push c:\crap\platform.xml /system/etc/permissions/platform.xml

Don't forget you need to do this under CWM recovery after first mounting /system

Hope this helps

bootloop with provided image...

About a week ago I successfully managed to root my Acer Iconia A1-810 using the Iconia Toolkit, also provieded from a thread here on xda.

The root was 100% and everything was working fine. However I weren't able to install from zip files from my standard recovery for some reason, so I decided to change...

A couple of days ago I downloaded the CWM recovery version 6.0.3.0 provided in this thread and flashed it.

Now I'm faced with a complete bootloop and can't seem to find a way around it.

I can't access fastboot because I guess apparently you'll have to start up the recovery in order to start it...(which is to me not easy to understand the reason of why, but at this point it doesn't really matter what I think).

And as perhaps you understand allready, I can't access my recovery because that's the one thing I flashed in order for my device to get to this state.

I have also tried getting into meta mode, but as soon as I plugin the USB cable into the tablet it tries to boot itself, consequentually putting itself in the bootloop.

There should already be a backup of the standard recovery internally stored on my device, I just need a way to access and implement it.

Someone please for the love of allah, ghandi, vishnu and all the gods names, help me out of this horrible mess I'm in.

Not really trying to be a jerk about it...But I did in fact install that CWM recovery under the 'false' pretenses that it was going to work, so I gotta say I feel kind of let down.

I'm about to start a new job, and was really counting on using my tablet while at work.

I'm really not pointing any fingers, I just want help...

[Android General] Sgt.Mindfudge:
Thank you for your response, I hope I weren't invasive when I also wrote to you in PM ^^

I appologize for my ignorance...Somehow I managed to skip that step...

EDIT:

I've completed the guide and now my tablet boots and the CWM works like a charm.

I can't thank you enough for pushing me in the right direction where others would've just been disrespectful and say something about not being an idiot and what not.

EDIT:

I noticed that when flashing using the guide provided, the date and clock on the device was changed, and the setting to automatically retrieve date and time was turned off.

If anyone stumbles across this problem (Which WILL make you unable to go online) it can simply be changed by going to Settings>Date & Time and either chosing the automatic retrieval and connecting to an online network, or changing the date and time manually.

Thank you a bunch, Shreps!

Much love <3

[Android General] Sgt.Mindfudge:
Wow....So, I'm back with yet another problem, haha...

Long story short, I installed gApps zip from CWM onto my A1-810, and replaced alot of my apps on my device, hahaha..

Some of them annoyed me so I decided to disable some of them...Then as I disabled the "Google App" it started uninstalling the so called updates, which was the entire content of it....

Now as it is, I have no homescreen...I can acces the Window manager, notification bar and settings through it.

I tried a factory reset just to see what happened but it was still the same.

I realize that I have to replace my entire rom, which I really don't have a problem with, seeing it came with alot of korean bloatware.

I managed to re-enable my USB debugging, and my CWM recovery is still functioning aswell as my bootloader.

However...

I got a bit conserned when I realized that the avalible ROMs are not really a full match with my Image version and build number, and seeing as I bet this is a korean-originated tabled I guess it's supposed to be like that, but I feel like I have to make sure by asking on here.

This is my current system information regarding this:

Acer_AV0K0_A1-810_RV0HRC03_WW_GEN1 - img version

Acer_AV0K0_A1-810_1.055.00_WW_GEN1 - Build Number

What I'm wondering is that if I can simply flash it with example: AV052.RV27RC03.WW.GEN1 or AV052.RV27RC03.AV052.RV31RC03.WW.GEN1 ?

The images above are the version names for specifically the Iconia A1-810 directly from acers download page.

Edit: I actually found the exact stock rom for my device on the link from the post above, but I'd still like to replace it if possible without the extra korean bloatware

For some reason when I'm trying to flash it with SP Flash tool it gives me the error message:

Edit: I loaded the DA_SWSEC.bin instead of the MTK_AllInOne_DA.bin and it seems like it fixed it.

But now instead a message saying my PMT has changed and I need to download it...

Would it be possible to use the old scatter file that I used to flash the preloader and recovery (from this thread) and simply put it in the same folder as the firmware imgs?

OR maybe I should make my own scatter file, and simply replace the recovery & preloader adresses in the stock scatter file?

Also you should strongly concider using the Iconia Toolkit to root from scratch using Linux.

That's what I did and it worked like a charm (on same image) and it's just a easy step-by-step even explained in the actual terminal as you're using it.

- I would call it an almost idiotproof method.

If requested, I could upload my own rooted system image, but it would mean for Me to re-assemble a computer to access a certain harddrive, so therefor only on request. Let Me know in PM if you really need it.

Hi

Try this method:

Download then install then run this app:

drive.google.com/file/d/0BzPzaKp_pZR6cjRNeGs3ZjRUams/view

The app is kingroot

Make sure that before you install the app, you must tick on check box unknown sources or extenal sources in settings of your tablet AND become a developer by tapping 7 times on build number in setting as well.

When kingroot is running , you tap on root then the app start to root. After a while your tablet restart. You run the app again, if your tablet is not root you tap on root again.

Tell me the result if you root ok.

I've been looking all over the net for ROMs & Recoveries for my B3-A20 and have yet to find anything other than the stock ROM on the Acer site. The B3-A20 comes with 5.1 and the A30 comes with 6.01.

From what I have found out they seem to be the same hardware.
