Hello, I have an Acer Iconia Tab A3-A40, Twrp and root via Magisk.

Magisk then told me that a new version is available.

The Magisk Manager, I could not start anymore.

That's why I switched to TWRP.

There I first tried to reinstall Magisk. Error message unfortunately no longer known.

Then uninstall Magisk. Also an unknown error message.

Restart attempt to TWRP.

Tablet just keeps restarting (bootloop)

TWRP can not be started via ADB (Fastboot) nor normally. Always restarting by itself.

Fasboot access is still available.

Start, it does too. Aver logo comes and then it starts again ...

What can I do?

Is there a way to flash the firmware completely via fastboot?

TWRP also starts not with: fastboot boot recovery.img

What can I do? Who else can help me?

Sorry for my bad English ...

Tab is for repair at Acer. So done

hi there. I am trying to revive my old A1-810. It has no system installed (previously it had been updatet to KitKat). I managed to unlock the bootloader and install CWM with support of external SD card. Now I think I should be able to flash original KitKat firmware, but links from first post are not working and I am not able to find correct firmware anywhere.

I believe I need this file: OS_Acer_Acer.AV0K0.A1-810.RV0BRC01.WW.GEN1_A44K_A.zip

Does anyone have it and is able to share?

Thanks a lot

EDIT:

OK, I have found the correct file but I had no luck with flashing. Neither the Kitkat nor the Jelly Bean. I am getting error status 7 "set_perm some changes failed" when flashing Jelly Bean and error status 7 "set_metadata some changes failed" when flashing KitKat. Do somebody know what is wrong and how can I fix this?

Unfortunately the answer is "NO" the bootloader is locked.

Hi, know this to old, but are u still have or know how to make test point for b1-710?
[Android General] Moriveon:
Testpoint for B1-A71 and B1-710

Hello. If you remove the back cover of your tablet and look just above the microSD slot, you'll see a grid of small pins called JP28. You'll need to disconnect the battery, and short Pin №6 with the right pin of the battery connector (Pin №3 of JP25). I recommend using a 1 kOhm resistor. Please check out the attachments with schematics.

Since B1-A71 and B1-710 have the same motherboard (Compal LA-A031P), this testpoint should work on both models.
[Android General] Os_Herdz:
Hi, thx for answer, this is like looks my motherboard, I can't see the jp25 and jp28
[Android General] Os_Herdz:
Sorry for the confusion, the box of the tablet said 710, one last question, what is GND, I know is ground, but where is it?
[Android General] Moriveon:
Try to use the GND pin of the battery connector. Judging by the schematics of your motherboard, it's possible to activate the Download Mode just by holding down the Volume+ button while connecting the tablet (battery should be disconnected) to the PC, you should give it a try before manually shorting pins, because it's easier!
[Android General] Os_Herdz:
I tried, but only appear like mt65xx preloader in device manager for phew seconds and then disappear, and I can't install drivers for that
[Android General] Moriveon:
It's correct behaviour. Your tablet successfully enables Download Mode and waits for SP Flash Tool commands from your PC. You'll need to find a way to install MT Preloader drivers to make it work. As far as I can remember, you'll have to disable signature checks for drivers if you run Windows 8 and older, but I can't advice you on that. Please search the internet on how to get the driver working.

Greetings,

I have a similar problem with my Tab Iconia A1-811. It got stucked in bootloop, so I gave up on it.

I have recently founded it in my bookcase, turned it on, and it looks that everything is still in good condition, except that software issue, so I did a bit of research on my own, and founded this thread.

After trying to install an official ROM from Acer site, I got error as if this is not ROM for this version, but on image link attached it clearly states my Tab is this exact version: A1-811_ww_gen1.

I would appreciate a lot if someone can help me solve this issue and install new ROM on it. Thanks in advance.

Recovery firmware for A1-811

Hello! You are trying to flash an image made for taiwanese devices, but your device seems to be made for european market.

You can download a firmware for your model from my storage, you'll need this file: "Firmware/MediaTek/A1-811/Recovery/WW_GEN1 4.4.2 RV02RC06 1.025.00.zip"

After this you can install a patch, you can either get it from the same folder in my storage (the file is called "WW_GEN1 4.4.2 RV11RC04.zip") or download it directly from the official Acer website.
[Android General] Xmaster6:
Recovery firmware for A1-811

Thanks, that went a bit further now, but few minutes after installation has started, I got another error. Is there maybe a solution for that. Maybe I should restart my device but then I have to wait a few hours before it goes into the recovery mode simultaneously, it wont get into RC using power button + volume up at all.

This time error is: script aborted (no error message) Installation aborted:

ibb.co/QvSRKQL
[Android General] Moriveon:
I'm not sure why the process fails this time. Try flashing your tablet with SP Flash Tool, you'll need a PC with MediaTek Preloader driver installed.

Get an SP Flash Tool for your tablet from my storage (look into "Software" folder), then a firmware for flashing ("Firmware/MediaTek/A1-811/SP Flash Tool/WW_GEN1 4.4.2 RV02RC06 1.025.00.7z").

After loading a scatter file, be sure to

un

check the "PRELOADER" and "DSP_BL" (if exists) partitions. Then click "Download" and connect your turned-off tablet to PC.

I recommend searching the internet for good guides or videos to understand the basic concepts of using SP Flash Tool (v3) before attempting to do anything with it.

Hi guys, so my brother has an Acer Iconia A3-A20. While looking at the Acer forums he found a thread called "OS upgrade for Acer A3 - A20" where a user stated

But since they can't talk about firmware not supplied by Acer my question is where do I find the latest Android version for the tablet (offical and unnoficial) and do I just follow the instruction on this thread to install it?

Also tried downloading the SPFT Firmware on the first post but the link is just a white page with text and no download.

ICONIA B1-A71 UNLOCK BOOTLOADER INSTALL ALLEGRO ROM

Hey guys, so my son brought me a iconia B1A71 I've managed a root with kingroot but was wanting to unlock the bootloader, was looking for the guide for bootloader unlock and each link I go to just sends me back to the firmware thread, I guess its cos its old thread now, anyone have a guide and what I need to get this tablet, custom rom etc?

##Edit ## OK so from the archives (4pda) I managed to install custom recovery and then allegro rom.. It would appear that a developer her spat the dummy out and removed the link to unlocking bootloader in xda.

Dear all,

This is my first message here, and I think I am quite a noobie :) Long story short : I am looking for the most lightweight custom ROM for my Acer Iconia One 10 B3-A30 tablet. Can you help me?

I have managed (I think) to unlock the bootloader, root my tablet through Magisk (with the boot.img stuff). Now it won't start up, but I can access recovery mode and potentially use adb sideload to install the OS I want (I think). I can't find any custom ROM for my device, and I clearly don't have knowledge to create my own. It looks like on this link there is a LineageOs version that would fit my needs, but the download link is broken.

How can I do to install a lightweight OS on my device at this point?

Thank you for reading, and I can explain in a detailed manner all the steps I have taken so far if needed.

Regards,

mmkdj

Hello,

As many of you I've tried to update Android from 4.2 to 4.4 on my Acer A1-811, but I flashed the wrong package so it's basically dead now (not responding to button pressing or charging. The only signs of life are when I plug it to PC - there is plug-in sound and plug-out sound after 3 seconds).

I tried to follow posted here steps, but instead of flashing ROM in Download tab I think I've unlocked the Bootloader. Now whenever I try to flash the ROM I've finally found, it displays Error 6102 and do not want to complete.

I've found @nikagl tutorial on how to flash it and what to do with Error 61**, but mentioned method of flashing only PRELOADER and than everything else doesn't work.

If I think correctly for my device I should use SPFT in version V3.1308.0.sn125 (Error 6102 is in this version, when I try to flash ROM in v5.1532.00 it displays Error 2004). I'm not sure however which version of ROM I should flash. I tried Acer_AV0K0_A1-811_RV02RC06_WW_GEN1 and mentioned error codes are from trying to flash this version.

Can anyone help me and tell if it is possible to make it run again and what can I do to achieve it?

Thanks in advance,

Supersu will not install via A1-810 Recovery System <3e>

I have, with some difficulties, been able to get CWM Recovery <3e> on my A1-810 KK installed. Mostly it was related to drivers fighting with me during the process...

But now I am unable to install supersu.zip via CWM Recovery <3e>. The installation aborts, and I have tried all versions from 1.99 onward. What could be the issue here? I have tried from SD card, from local storage and to no avail, all of them fail fairly early at install... Most of the files have been locally downloaded and the zips are 'correct'.

Dunno where to go from here... Maybe fall back to the Toolkit? Is there a way to see where CWM Recovery <3e> chokes? Install a really old version of Supersu?

-- EDIT --

After hints from [MENTION=5266476]LaosPerson[/MENTION] and [MENTION=5737085]Optimissimus99[/MENTION] I ran the first restart after flashing DIRECTLY INTO RECOVERY, and lo and behold: CWM 6.0.5 is the recovery now! Then I was able to install SuperSu 2.0.2 from ZIP file without any problems. See added attached images...

Thank you all for helping an old fart like me out!

[Android General] Just_Another_N00b:
You are so right. I will adjust text...
[Android General] Moriveon:
[MENTION=4523909]Just_Another_N00b[/MENTION]

To flash SuperSU you need to unlock your device first.
[Android General] Just_Another_N00b:
I followed your unlock+bootloader instructions. And the english translation of the russian instructions... What else is needed? I thought that process would unlock, set up bootloader and recovery, or is that a wrong assumption?
[Android General] Moriveon:
[MENTION=4523909]Just_Another_N00b[/MENTION] So, you unlocked your tab (using XDA guide I hope) but still having stock recovery, right?

Try to flash 4.4 firmware and unlock again.
[Android General] Optimissimus99:
Just flash again, and after unlock STRAIGHT Boot into CWM, if you Boot in Acer system, it restores 3e recovery
[Android General] Just_Another_N00b:
Right! I read something like that before in this thread, and I was not sure if the <3e> was the supposed recovery or not. I followed the guides (both) too literally.

Thanks for the info. I thought it was something I failed to do (and it was!). I have run this unlock/recovery thing about 6 times now, and I was not sure if it worked or not. And the cryptic info on that step of directly going to recovery was valid for all A/B Iconias.

I will run the whole rigamarole again and start into recovery right away. Maybe this just needs to be clarified in the guide and not the info there of checking if you can boot into Android.

FireDiamonds step 16 (and new 17) should read:

16. Close SPFT, disconnect your tablet and start into recovery (Power and Volume+) right away. Answer the question posed there affirmative.

17.1 If you are stuck in the Acer Logo, press Reset and boot again

17.2 If your tablet is not reacting to anything, reflash using the Rescue folder

Same holds for the Russian step 19 and forward.

By the way:

The Russian guide is slight more elaborate on what/how to use for the Rescue step.

Still [MENTION=5889030]FireDiamond[/MENTION] is the best!

---------- Post added at 12:06 PM ---------- Previous post was at 11:08 AM ----------

I rebooted into recovery DIRECTLY AFTER FLASH (redid it after [MENTION=5737085]Optimissimus99[/MENTION]'s hint of rerunning whole process, but restart into recovery right away), and it worked. Could also then easily install SuperSu 2.0.2.

The only item now is left is the CWM 6.0.5 question on fixing root. Because of the age of CWM I think it is a moot question, but still.. Yes or No?
[Android General] Optimissimus99:
I typed yes, and root worked (but without /system Write permission)
[Android General] Moriveon:
[MENTION=4523909]Just_Another_N00b[/MENTION]

Fixing root on your tab won't do anything. You can flash SuperSU, but you'll have not full root (can't mount /system in RW).

Root is blocked by kernel. When Acer will release 4.4 Kernel Source code, we'll be available to make kernel w/out blocking root.
