Hello,
I hope it is the right place to ask for help .... The automatic system update failed and now the tablet is stuck at Android System Recovery Screen. Wipe Data / factory reset does not bring the system back, so I guess I need to upload rom / update from sd card - I got option "apply update from sd card".
So, please, help me to recover from this situation as my tablet is stuck .... I do not have or could not find the right files to use with "apply update from sd card."
Or, any links to the tutorial for updating / uploading rom for this model will help ...
Thank You very much in advance.
Kindest Regards
Lukasz
I solved the problem by uploading the rom again.
1) SPF Tool + MTEK drivers for win
2) Official ROM
Just two things:
a) if SPF throws error you need to choose upgrade firmare not download
b) you need to take off the back cover and unattach the battery otherwise it will not work
Have a nice day
Lukasz
Hi !
Thanks for confirming that you solved your problem !
I will now move your thread to the dedicated section .
Cheers
Hi everyone. Just did the solution like what Luqpa_W said but my tablet is still bootlooping on lenovo screen. There is no problem during flashing and everything seems fine during flashing. I do not really understand what is the problem with my tablet. If someone knows how to deal with it, please let me know.

EDITED: My tablet just got booted! After several times of reboot, it seems working. Thanks!

Hi all:crying:
Description :
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.
A2: If you cannot apply any Acer firmware, because you always get a partition error while installing, you should do a reboot after you get the error. A user reported that this made her/his device boot into Android again, showing the new version in settings -> info. Good luck
A3: If the A1 and A2 didn't help. Send back the device to Acer. Tell them you tried to apply an update from sd card and ended up in this bootloop. Sending device back to Acer over UPS is free. Good luck!
I failed root my AIT A1 and now im trapped in bootloap (my fault,RTFM fail.) I try find somewhere *.zip with official FW to apply it back trough recovery. Got any one advice how solve this issue? On acer.com is nothing usefull.I know how fix but cant find files witch i need....Ty for your time and LINKS...or Ideas
Help ...

Have you unlocked you tablet? If you have, why not use a custom recovery (TWRP for example is a powerful yet simple to use recovery)? If you haven't, then it was a bad idea trying to root your tablet.
Please reply so that I can help.
Reupload A1-811 ROM
Can anyone reupload the original stock ROM? I want to unbrick my tab but hotfile.com link from the first page is down
Thank you
In case anyone else ends up in this thread, the solution to get an A1-811 out of a bootloop, ie. "unbrick" it, please follow the Firmwares for flashing - [EN] guide from this thread:

I have similar but can still go into recovery. In recov the internal sdcard won't mount, so I just think the memory is fried...
Unless you're prepared to solder stuff or replace the MB I don't think there's much we can do...

Hi
after rooting my acer iconia a1-810, tablet keeps locking screen after 0,5 sec. so I can't enable usb debugging and I can't install different rom with Acer Iconia v0.8.1 toolkit
So i tried install different rom from system recovery, but I get check.partition.size=[__PROP_UNDEFINED__] error,
maybe somebody know how to fix this error ?
This error like error in rom file. In this situation you can help rom build author. Or needs more details.

I installed RV18RC07_WW_GEN1 rom from [ToolKit] Acer Iconia v0.8.1 page, first I stuck in boot loop. than i tried install update.zip for that rom, during installation proccess I got that partition error, but my iconia after restart booted up, but stuck with always locking screen.
probably I chose wrong rom version for rooting
maybe I can revert that process or install decent rom via fastboot, what do you think ?
after all my screen wasnt locking down, just lights turned off after half sec. pressing volume up and down I kept screen on, and I manage to enable usb debugging mode in menu.
I unrooted with RV18RC07 stock image, but it did not solved my problem.
Can I flash different rom for example stock RV03RC08 over stock RV18RC07 on acer iconia a1-810 ?
check it maybe will help, good luck !
I bought my Acer A1-810 it’s 2,5 months (from amazon). And few days ago I decided to root it. 1 hour later i realized that was not a really good idea, because i did not know much things about, and it was not as easy as I thought. and voila as a result : bootloop !
I tried different roms, different update.zips but got allways the same error : ” check.partition.size=[__PROP_UNDEFINED__] ”
I was desperate…I was at the point of resend it to Acer for repair. But last try was successful, I did it, I did !!! And there is how !
1. go to acer web page --->support--->drivers and manuels
2. choose your model acer a1-810
3. As my divece was bought in usa, my FW upgrade is AV052.RV26RC06.PA.CUS1 (in O.S ), download it !
4.when it’s done, you should unzip and should get update.zip separately.
5. Put update.zip on SD card
6.Put SD card in your device.
For next steps see the manuel of update
Dead

I did as you guide ...
The upgrade is success and i press power button for reboot. After that my tablet is dead. tried following all of Acer's recomendations (vilumeup button + power button, popping battery out, hold power button in and then insert charger, stick a paperclip in reset button hole, etc). nothing works.
My tablet image version Acer-av052-a1_810-rv03rc08-ww.gen1 Please put the Flash file to it in this post thank
Hey did you by any chance find a fix for your problem? Cuz I'm having the exact same problem and I can't find any solutions anywhere.
hello
so last time i wanted to install that "touch fix" for my Chuwi vi8, after a reboot my tablet wasn't able to boot anymore, it just won't stop to reboot, i can still boot to Windows with lock+up volume + home button, i can also go in the stock recovery mode, yes i already tried factory reset and it didn't worked, how can i fix it ?
i can also get clockwork mode but i just have error closed... i installed all the drivers i was able to found but no one fixed the "error closed" when using sideload, also i don't know WHERE IS THE STOCK ROM...
I have this www needrom com download chuwi-vi8-dual-os
"file is too big" so i format in NTFS but then the tablet won't recognize it, and seems like it's the WINDOWS ROM i don't need the WINDOWS ROM I JUST NEED THE STOCK ANDROID ROM
i've been trying to fix this since MONTHS, tried yesterday, it took my whole day today and yesterday STILL NOTHING.
i reposted this here beacause i think i wasn't in the good category sorry i'm new
IF someone can REALLY HELP ME, do i'll have to PAY SOMEONE to fix my tablet ??? Like really, i already posted this in december no one answered me...
Ok, so it can't be fixed, great ! Thanks ! XDA brokes my device and won't repair it....

Hello everyone!
I have a huge problem with smartphone mentioned in the thread title.
Once i wanted to install Cyanogen mod on it (yes, i rooted my device before flashing new room) and everything was well until the final reboot of the device.
Well, it is in bootloop. It only shows animated Cyanogen mod icon and nothing else.
I still have access to Droidboot that has an active "SD Download" option.
Is there any possible way to repair this device? Even with clean android?
I would apreciate any help whit this thread.
Well, noone seems to know solution to my problem, so i figured it out myself.
I am posting solution to this problem so if anyone in the future will have this issue, then he will have solution right here.
1. I downloaded stock android from asus website (Version 4.1.0 if i recall).
2. I copied the .RAW file to SD card and put it in smartphone
3. I booted up Droidboot and choose "SD Download"
4. I waited a while and after the instalation is complete, i booted up the system
There still was a bootloop but now with the asus logo. But then, i made another step:
5. I booted up Droidboot again and choose "Wipe/reset device"
After that, it worked like a charm
The stock android didn't have drivers for the Back, Home and menu touchbar so i made i think four system updates from android update software and it worked.
I hope i will help somone wit this thread.
Take care everyone
