Acer Iconia A3-A20

Hi everyone,

I have an Iconia A3-A20 and it's always rebooting. I tried the factory reset and nothing. For what I've been reading in the forum, It's possible to use a factory image in a SD card to get back my tablet. Can someone explain me how to do that?

File SD_Acer_AV0K0_A3-A20_1.015.00_WW_GEN1.zip begins installing but after 20 seconds gives an error and stop.

Thanks

[Android General] JanniekM00:
Try the 1.018.00 zip file

I downloaded that file now but it stops at the same point of the 1.015.00.

Try to use SP Flash Tool for flashing firmware.
[Android General] j.simoes:
Let's see if I understood. I have to use the Sp Flash with the 1.018.00 zip file...

When I tried to load the scatter.txt file, it says:

Error: Initializing scatter file failed.

I never used SP flash, so I don't know if this is the right procedure.
[Android General] nikagl:
No other messages? Just Installation aborted? Please post pictures of errors if you want help...

You need to follow the guide.

my tab is iconia b1-a71..
[Android General] nikagl:
As always, please post screenprints, foto's or whatever you can make with the error in it.

If your tablet now fails to boot, try to flash only BOOT and RECOVERY using the following guide:

http://pastebin.com/raw.php?i=4FYSSUk8

If that fails, flash the whole SPFT firmware, relevant for your device using the above guide.

And again: post error messages, screenprints, foto's, etc., for any errors otherwise we will not be able to help at all :(
[Android General] j.simoes:
First of all, I'd like to thank you all this information, but I cannot install the MTK driver. When I plug in the tablet, my laptop recognizes a MTKxx driver but it only appears for few seconds because the tablet begin to charge the battery. If I try to install it when the battery is charging, I get an error. The guide says that I should remove the battery but I cannot even access it, so how can I remove it? The A3-A20 specifications says that we cannot remove this model battery... Is it true?

I could bring the tablet to the supplier because it's new, but I bought it in Europe and I'm working in Africa right now, so the only solution is continue testing how to get my tablet alive again.

Regards,

Joao
[Android General] nikagl:
Hi Joao,

I would try to use a different cable, different USB port or different laptop. This often happens when there's something with the connection to the tab...

Anyone else other suggestions?

Hi, I was flashing my A3-A20.

However it didn't flash, show error code 2004, tried other usb ports but still not working.

Someone please help..
[Android General] Moriveon:
Throw your tab in the trash can, it's unrecoverable.

But, if you know how to use TPs, maybe there's a chance...

Btw, where are these people with A3-A20s coming from? I see too much questions about A3-A20 last time...
[Android General] nikagl:
What ROM did you flash? How did this happen?
[Android General] milogen:
I am trying to flash AV0K0_A3-A20FHD_1.023.00_WW_GEN1 , followed the steps in this thread but keep hitting error code 2004 and 5054.

My tablet model is A3-A20FHD , Acer_AV0K0_A3-A20FHD_1.023.00_WW_GEN1 is the only ROM i can flash.

Use SP Flash tool to flash stock

Verstuurd van mijn GT-I8190
[Android General] nikagl:
Do you have A3-A20 (as mentioned before) or A3-A20FHD (as you mention now)? There's a big difference between the two and you cannot flash a ROM for the one to the other afaik.
[Android General] milogen:
Hi, do you mean use SP Flash tool to flash the "Firmwares for stock recovery" which listed at 1st page ?

---------- Post added at 12:30 PM ---------- Previous post was at 12:29 PM ----------

sorry for typo, I am using A3-A20FHD.
[Android General] JanniekM00:
Yeah i mean that
[Android General] nikagl:
The stock firmwares for recovery are usable if you can access recovery. You can also flash a stock firmware using SPFT. That has always helped me getting them out of a bootloop. You will lose all of your data on the tab, because you're flashing an empty USRDATA (you can try leaving the USRDATA checkmark in SPFT off).

I would do this again.

Read this post:

http://xdaforums.com/showpost.php?p=59693904&postcount=480

Take all steps. Make sure to download the A3-A20FHD Flashtool and Firmware!

As I do not have the device, I cannot help you other than advising you to follow the steps exactly. It should work...
[Android General] milogen:
Hi, thanks for the information.

The post i have read for several times yesterday, and understand all the steps already.

I am unable to access to Recovery, and stucked in bootloop.

Does the SPFT able to flash the file "SDs_Acer_AV0K0_A3-A20FHD_1.023.00_WW_GEN1.zip" ?
[Android General] JanniekM00:
No... You must download SPFT firmware. Link for your device: http://cutt.us/e5Smh
[Android General] nikagl:
Right. Make sure to use:

SP_Flash_Tool_exe_Windows_v5.1352.01.zip for A3-A20 & A3-A20FHD

A3-A20FHD| KK | http://cutt.us/e5Smh | 9b3c816da5e843a90c1c8a16af14d44b | AV0K0_A3-A20FHD_1.023.00_WW_GEN1

I am not home, so cannot look for other versions of the SPFT image file...
[Android General] milogen:
there is only version 1.023.00 for A3-A20FHD, i downloaded it twice and still not working.

Hope you still have keep other older version in your harddisk .
[Android General] milogen:
I am using Windows 7 64 bits, and installed MTK drivers.

I unable to off the tab by just pressing the power button, because it will keep restart in bootloop.

So i use the pin and push the soft reset button next to the volume button.

After that i run the SPFT, when i clicked Download, the bar run 100% in red color, after 10 secs, error code 2004 and 5054 prompt out, then the tab boot from the battery charging screen to Acer bootloop screen, and keep restarting.

If my steps above is correct, does it mean that that is MTK driver problem?

I tried the drivers in Windows XP 32bit, but still the same result, I used other USB cable and still the same result as well.

EDIT: How to turn the tab off completely ? as the battery in built in we unable to plug it out.
[Android General] nikagl:
I don't have A3-A20FHD so not sure, but for other tabs you can long press power to really turn it off. Or open tablet and disconnect battery (dangerous: warranty breach).

Are you 100% sure you have A3-A20FHD?
[Android General] milogen:
Yes i am very sure, box and the tab backside has written.

I have many years experience on flashing rom, among so many brands, i can say that Sony and Acer has very limited custom rom and also recovery, and less resources for people to flash the rom alternately as well.
[Android General] nikagl:
So... instead of using reset button, try really to turn the device off (long press power off, at least 20 seconds, remove battery or let it drain till it's 100% empty), and try running SPFT again after it really is powered off...
[Android General] milogen:
tried long press, but wouldn't help. battery is built in, so i won't risk myself to disassemble the tab.

i think that's it, after a 48 hours tried, i decided to send it back to the supplier to claim the warranty.
[Android General] milogen:
Went to Acer service centre and my tab back to alive, and they upgraded version 1.023 for me, just 15 mins of waiting.

I guess the A3-A20FHD SPFT firmware has issue, someone may test it when you are free.

*SIGH*

I have just purchased a second hand B1-720 for my daughter to use, I would like to root the device for software such as FolderMount and App2SD.

I have been flashing roms and rooting devices since I bought my Galaxy S WAAAAAAAY back when. I realise that this device is a whole different beast and it is one I am struggling to tame.

What I have tried so far:

Acer Iconia Toolkit (using both Ubuntu and Windows and realise that this software doesn't work with my device)

The guides linked off the OP in this thread however the embedded links don't work.

Please, Please, Please could someone give (point me in the direction of) a working set of files including the correct Drivers to install on Windows 8.1 64bit.

System Details:

Model: B1-720

Android Version: 4.4.2

Kernel Version: 3.4.6

Image Version: Acer_AV0K0_B1-720_RV0BRC05_WW_GEN1

Build Number: Acer_AV0K0_B1-720_1.070.00_WW_GEN1

Image P/M: FM.NMXA0.01V

Spent the last 3 hours trying to get this stupid device unlocked and rooted with absolutely ZERO joy.

Can someone please help me get this thing set up so my daughter can use it for our upcoming camping trip??

Cheers
[Android General] nikagl:
Hopefully there's some people on this thread to comment about B1-720. I have read several posts of failing to install CWM using the [MENTION=5889030]FireDiamond[/MENTION] guide:

http://pastebin.com/raw.php?i=uWfHHyZL

Did you try? I think that's the only way currently documented? I guess using the Toolkit should be possible too, but that will keep your /system in readonly mode because mounting /system won't be possible using that method. What happened when you tried using the Toolkit? I think it would be better to discuss that in the toolkit thread so others that used the toolkit can comment too :)
[Android General] Moriveon:
I don't think your daughter will be busy with Root/CWM thing while camping, so do you really need it? :D
[Android General] lembi2001:
Yeppers, need it. I have got a 64GB SD Card installed to move some of the larger files to using FolderMount, thuis freeing up space on the actual device. FolderMount requires root so without it I can't set the tablet up properly

[MENTION=3245659]lembi2001[/MENTION]

Well, as I can remember, when I was working on unlocking B1-72x tablets, I had A LOT of problems I've never met while working with other models. And as I can remember, nobody has tested B1-72x unlocking yet (at least on 4PDA)... Just know that you can brick forever(!) your tablet! And you won't have enough time to fix it before yur trip.

My suggestion to you is try to avoid of unlocking this tab, BUT also rooting is still stable (mostly on JellyBean).

Good luck!
[Android General] lembi2001:
Thanks for the reply. I assume then that I am stuck without root due to the fact that my device is on on KK

[Android General] lembi2001:

I have literally tried EVERY method I could find online but nothing works.

I have recovered from numerous boot loops and I'm convinced this Tablet cannot be rooted.

All I want is to get the full use of my SD Card back after KitKat ruined it.

I don't have a prerooted image and most of the links to downloads on XDA Developers site don't work, files are missing or moved etc so these rooting guides are useless.

I also don't see "preloader_unlock.bin" in: "15. Check files:

PRELOADER "/811 Unlocking and CWM"/preloader_unlock.bin" When I use China gadget reviews method.

Is there a WORKING root for the A1 811 or am I wasting my time?

Nope :(

I have an A1-811 and never had any issues rooting it. It bootlooped once or twice when I initially developed the root from scratch procedure in the toolkit, and I was always able to recover it by simply flashing the full ROM posted in the guide mentioned in this thread:

in the second step i flash the second scatter the one with all items but instead of firmware upgrade ,i put download mode and gave me an error and now i connet the tablet to the pc and turn on a light in a 1 sec and then turn off and the pc does not reconise the driver

any help plzzzz

I think the SAME goes for me yesterday. Let's cooperate!

I used Vroot to get root access and it was successful. Then i tried to install CWM with Flashify 1.9.1 (Recovery image). Device rebooted and entered infinite bootloop.

I'm using this guide to unbrick my A1-713HD. When i start downloading with SPFT It always end with BROM ERROR: S_BROM_DOWNLOAD_DA_FAIL 2004. Any ideas, friends ?:)

Device: Acer Iconia A1-713HD

Android 4.4.2 (stock firmware)

Root: Vroot 1.8.5.15285, BusyBox 1.23

OS: Win7 x64

For now i'm using SPFT 5.1420.03/5.1528.00.000 with Acer_AV0K0_A1-713HD_RV05RC03_WW_GEN1_DCC. Installed both drivers for SPTF and Acer. While first plugin i see MediaTek PreLoader USB VCOM port (COM7) is ready for use.

Trying this, no help yet.
[Android General] DaniloPT:
yeap same problem, but now only power on the red light,and the acer logo doesnt appears and pc doesn reconized preloader drivers
[Android General] RealJhad:
1) Plug your device to your PC with USB cable (a good cable, on a direct back USB port, avoid front USB ports)

2) A "MTxx Preloader" device should appears for a few seconds, install drivers for it

3) Unplug, replug the USB cable, your device should be well regconized (a COM device in USB Ports & Com)

1 and 2 is good enough, i can see MediaTek PreLoader USB VCOM port (COM7) is ready for use, so drivers are okey. But unfortunatly at third point it doesnt show any device in Windows device manager and the device continues to reboot each few seconds ( i can see how it changes between Battery screen/Acer Logo screen/Black Screen and also i can hear the sound from PC (plugging/unplugging)).

It happens w/wo battery.

Hi all,

I am not sure where the confusion is, but:

[MENTION=5874504]DaniloPT[/MENTION], you have not posted which firmware you were on and which firmware you have tried flashing. You have not mentioned which SPFT version you are using either

[MENTION=5914777]RealJhad[/MENTION], you mention an SPFT version you tried when flashing which are not mentioned in the posts [MENTION=4493088]Shreps[/MENTION] has created

When flashing/unbricking, etc., please follow [MENTION=4493088]Shreps[/MENTION]'s guide:

http://xdaforums.com/showpost.php?p=59693904&postcount=480

Flash firmware AV0K0_A1-713HD_RV05RC03_WW_GEN1 with SP_Flash_Tool_exe_Windows_v5.1352.01.zip as mentioned in that guide.

Make sure to try different PC's, different USB ports and different USB cables if flashing fails. How unlogically it sounds, I have had several times that a port, PC or cable failed and it worked when using another.

If that does not work, I do not know what to do either. I do not have A1-713HD and cannot reproduce this... maybe someone with A1-713HD can respond in that case?

[Android General] nikagl:
I'm afraid I don't know. I don't think there's any guide that tells you to format a device using SPFT, and I don't think anyone has really tried that yet. All you can try to fully power off the device (long power off and/or remove or drain battery) and try again (possibly without battery, sometimes that helped). If none of that helps you will need to find Test Points but I don't think there's many people in the community with that experience... bringing it to a service center should also work, many people reported that they can revive tabs where we can't...

I do everything right okay?

i have a lot of experience installing roms because i had 5 android and all with roms.

2 point , something here its wrong , i use the file to install via sp flash tool, everything correct, drivers all !!!!ok!!!!!!

3 point, something is missing in the firmware of this tab so please check again or remove it because the tabs are deading, is not only my case , some people here are with the same problems , so the problem is on these files.

i dont have more solucions. i go back to the shop and try solve this problem, please people dont install any of this files , you gonna kill or devices.

[Android General] nikagl:
What ROM version were you on? What exact steps did you take when it started bootlooping?

Fixing bootloop can mostly only done by:

* restoring a backup you made before you started the whole thing

* flashing a full ROM using SPFT (see instructions main thread)
