[Android Q&A, Help & Troubleshooting] renojim:
ligalui, thanks for getting back to us! I think the Toolkit isn't quite right. I believe it tries to write busybox to /system/xbin using adb, but we don't have write access to /system. I'm going to have to post in the Toolkit thread to try to get some more knowledgeable people involved in the discussion. The reason I didn't have any problem is that I had rooted JB and under JB the Toolkit was able to write to /system, so I already had busybox installed.

ligalui, just to verify, could you try the following commands in a terminal window?

su
mount -o remount,rw /system /system

or

mount -o remount,rw /system /system/

I'm betting you'll get a "permission denied" message.

I didn't know we could unlock the bootloader, but I'm also not sure what that does for us. I do know that it was a big deal to some people. I've heard of CWM, but I have to admit I don't really know what it does.

Tyfighter98, I think I can come up with a way for you to install busybox manually (unless you'd like to try ligalui's method).

[Android Q&A, Help & Troubleshooting] Tyfighter98:
Ya if you found another method I am all ears.
[Android Q&A, Help & Troubleshooting] renojim:
Ok, I think it's actually not too hard to install busybox. There's two files from the Toolkit you need to get onto to your tabet; I'd recommend putting them on your microSD card. The busybox executable is in 'acer_iconia_toolkit-0.9.4_32bit/bin' (for me) and the tarfile that contains the necessary busybox links (and su) is named 'a1su.tgz' (it's in 'v0.9.4/acer_iconia_toolkit-0.9.4_32bit/bin/a1' for me). I haven't looked into why su gets installed properly but busybox doesn't, but anyway... Find those files in the Toolkit zip and get them onto your microSD card or somewhere on your tablet. The commands I give later assume you put them in '/storage/sdcard1/sysimg'. If you need help with getting them on your tablet, let me know.

Now you'll need to follow the steps I gave earlier to save and mount the system image (up to the "cd /data/local/mnt" command). Once you're in that directory, you're essentially in a copy of /system. Run the following command to copy busybox and create the appropriate links:

/storage/sdcard1/sysimg/busybox tar xvfz /storage/sdcard1/sysimg/a1su.tgz

Now you have to restore the system image you just modified, so follow the steps I gave to unmount /data/local/mnt (make sure you're no longer in that directory - cd /) and copy the modified system image back to the tablet.

It's hard for me to know which of the commands I gave earlier require busybox in the first place, so if a command isn't found, try prefixing it with '/storage/sdcard1/sysimg/busybox '.

Good luck! Let me know how it goes.

News on A1-810 KK

ayfamoks, maybe you can try the "Unlock Bootloader/Preloader + Flash CWM Guide by [MENTION=5889030]FireDiamond[/MENTION]" guide for recovery bootloader.

Renojim and others, I try the "A1-810 BW Remover by GreatAR@4PDA and Moriveon@4PDA" guide to remove the bloatwares:

1) It worked, but now Google Play Store gives me error every time I open it, any version of play store I find ( modded or not). Sometimes, it run until I try to download an app, then it closed and I can't start it without error;

2) I am amazed that bloatware removers worked, because my /system folder doesn't have the permission of R/W; with Emulator Terminal I receive the usual error "mount: Operation not permitted", while in recovery mode that command, in a script, works ( I recommend you to see the "updater-script" file). Is it possible to somehow instill the permissions we want to the /system folder?
[Android Q&A, Help & Troubleshooting] renojim:
ligalui, that's interesting. At first glance, it looks like it's just using busybox to mount, but it runs under recovery mode? I'm not really familiar with recover mode. Do you know if this requires CWM? I'm thinking it does. I'm going to have to look into it further when I get a chance which unfortunately may not be for a while.

I remember when i was rooting this, it was going well but when i wanted to put some files into the tablet it was doing the same thing- charging and discharging the battery. What should i do if there is any chance to unbrick it? And yes, i have tried unplugging the battery and using the reset button.

Also once when i forgot that i shouldn't change dpi, i changed it but i was able to put the dpi back to normal, after that the systeam app- systemUI was not working and i was using that device about 1.5 year later- the notifications bar and system buttons-home, recent apps, back I made in Tasker.

Superuser not working with 4.4, SuperSu works

First off, thanks for writing this tool. I've been a bit hesitant about rooting and wanted to figure out how the process works and what recovery options I have beforehand, and reading your .toolkit.py code was enlightening. The code is well-written, well-structured and has some useful comments, so that was very much enlightening.

I've tried rooting my A1-810 running 4.4.2 from scratch using superuser (the supersu install has a bunch of extra files that I didn't understand, so I decided to go for simplicity and use superuser). However, this didn't work - launching "su" through the shell outputted "255". Looking in the logs showed some error about a connection failure. Reading up on the "su daemon" concept showed that due to SELinux, Android 4.4 and up requires running a su daemon in addition to the su binary. I think the superuser package does support daemon mode, but it requires additional setup.

In short, it seems that Android 4.4 is not supported by the "Superuser" option in the toolkit. Usering SuperSu works as expected, so perhaps a note should be included?

One more thing I wondered: The install-recovery.sh script used by supersu works, but it would be nicer to use a proper init script instead (the script also includes a note about this). Did you ever consider implementing this?

Hi everyone!

I have Acer Iconia A1 - 810, Runing KitKat, the scr from about tab:

I rooted it with Toolkit 0.9.4

It seems to be half unlocked - I Have SuperSU - Root Checker says i have Root permissions...

But System is RW protected - i can't change nothing in System Directory...

I just wanted to do one "small" change - Swap the sd with internal memory...

In the system dir i have the files:

fstab, fstab.fat.nand, fstab.nand

In etc no vold.fstab files...

I can only view the fstab, without perrmision to save any changes, and error when try to edit fstab.fat.nand and fstab.nand - read error.

Is it possible to swap the sd with internal memory?

If Yes - can someone tell me how?

[Android Q&A, Help & Troubleshooting] renojim:
grany, I hope someone else chimes in with more information. The last I heard, we've been waiting for Acer to release the kernel code so that the system r/w problem can be overcome. I haven't heard if that ever happened, but I haven't been keeping up with the latest developments.

I too would like to substitute external memory for internal since my A1-810 is now giving me an "insufficient space" error when I try to install any new apps (even though I have hundreds of MB available :confused: ).

It is possible to save the system image, mount it as a loop device, make changes, and then restore it. I gave some scripts I use here. If you decide to do some experimentation, please let me know how it goes.

Edit: For anyone that comes across this from the "insufficient space" message, I had to uninstall the Play Store and revert back to an earlier version. No amount of clearing data or caches did any good.

[Android Q&A, Help & Troubleshooting] renojim:
Are you sure you're root? It doesn't sound like it since fstab is readable to anyone and the other two aren't. Did you type "su" at the command prompt? For what it's worth, all three files are identical. I think the Toolkit was supposed to install busybox, but I also think there's something wrong with the Toolkit and it doesn't do it properly. I probably have it because I had rooted my tablet previous to KitKat and it was installed at that time.

Now that I look at it, fstab, et al, aren't located in the system image. They're in rootfs which is mounted ro. You can remount it rw (if you're root) and then make changes to any of those files. You may need busybox to be able to remount it, however, so you'll probably want to work on that problem first. I gave an untested method to install busybox here.

Did I brick my Acer Iconia A1-810?

Hi,

I hope I am correct in Posting my Problem/Question here.

I have an Acer A1-810 Tablet and since I never got an update prompt (I was on 4.2.2), I opted to manually flash the Android 4.4 Firmware using the Stock Recovery.

I visited Acer's driver Page and got the 4.4 Firmware "Acer.AV0K0.A1-810.RV0BRC01.WW.GEN1". I put the zip file on the external SD card and flashed it and it completed successfully.

But when trying to boot the acer logo showed indefinitely and it wouldnt boot correctly. So I thought, I just flash the stock 4.2.2 again from the Acer website. There are multiple choices and i went with "	Acer.AV052.A1-810.RV31RC03.WW.GEN1". I have also tried a few of the others but all I am getting are Bootloops :-/. In the Process the Recovery seemingly got updated since it looks slightly different now and now when I try to flash any of the 4.2.2 firmwares I get the error message "assert failed: getprop("ro.product.name") == "a1-810_ww_gen1" . So apparently I do not have the ww_gen1 Version?

Before I did all that I was planning on Rootinng the device via the toolkit from this forum. I never got to the point of actually flashing a rooted firmware but through the process I know that my Stock firmware was "RV18RC07".

But unfortunately on Acer's website the only firmwares available are

RV18RC09, RV26RC06, RV27RC01, RV27RC02, RV27RC03, RV27RC04, RV27RC07 and RV31RC03

Is there anything left I can do? I reckon I need the stock RV18RC07 zip file to flash? I unfortunately cannot use the one from the Iconia Toolkit Thread, because I cannnot boot my device to make the toolkit work :-/
