Hi nikagl.

Thanks for the toolkit!

I think it will be useful to extract linux-specific actions from "Root from scracth" action to some separate action like "Root image only", so it will be possible to pull image from device using Windows host, use Linux VM to just root pooled image, and then push rooted image back to device using windows host again (using "root with prerooted image" target) for better stability (low level communication with device from VM looks risky).

Thanks.

system rw

I just updated my A1-810 to KitKat and successfully rooted with v0.9.4 of the Toolkit. A big thanks to all involved in creating the toolkit.

I've seen mentioned in the toolkit thread various issues with mounting /system rw, but there seems to be conflicting information and a lot of the posts occurred before KitKat. My first question is whether it's possible to mount /system rw on an A1-810 with KitKat? I've tried the xbin BB mount and the .mount_wrapper mount and both give "permission denied (are you root?)".

As recently as 2/14, Nika makes the comment that the system.img he uploaded has no system rw, but that's for an A1-811 and it's not clear whether it's impossible or if it was just left out of that image.

If anyone can help, I'd really appreciate it!

I can´t find a system.img.gz for my a1-810.

But as i understands it, i can pull systems.img.gz from my tablet using function "5".

Then it will be rooted, and copied back.

Is that right procedure using Windows without a downloaded system.img.gz?

Hi Nika

Just ran version 0.9.4 on Windows 8 64 bit.

Everything worked like a charm! ;) Thanks.

After pulling the system.img.gz. what steps need´s to be done to root the system.img.gz?

I am i bit unsecure on this.

I have pulled the file, it is in the folder, but i think something needs to be done to root the file.

Or maybe it is rooted in the pull process.

And then all i need to do Next is to restart the Tool and choose "root" in the menu?

I hope you will help with this.

Thanks in advance
[Android Q&A, Help & Troubleshooting] renojim:
I used Linux running in a VirtualBox on a Windows machine (so basically, I used Linux). I think I could have done everything within Windows, but I recall seeing issues with Windows in the past posted in the Toolkit thread and since I already had an easy way to fire up a Linux machine, I just went with Linux.

You don't really need to pull the image unless you just want to see if it will work. The "[1] Root" choice will then present an option to "root from scratch". That option will basically perform the steps you illustrated - pull the system image, root it, and then copy it back. I should note that the steps that it says may take up to 15 minutes (pulling the image and pushing it back) took closer to 30 minutes for me, so you may need to be patient.

If you have any more questions, just ask!

Now if I could just get r/w access to /system...

[Android Q&A, Help & Troubleshooting] renojim:
I don't have a Liquid S510, but I'd try to get the adb part working first. Look for adb.exe in one of the subdirectories of the toolkit and type "adb devices" from that subdir with your tablet connected to your PC. Also, do you get some kind of message or notification from Windows saying your tablet is connected? I'm guessing if you can't get adb to work then you'll never get the tookit to work.

Hi, I did the Root from scratch procedure for my a1-810 kitkat, but i don't have the permission of RW on the /system folder. Also, I can't install Bubybox, that says "It looks like the installation of BusybBox was not succesfull. Try installing to a different location, that may resolve the issue". What can I do?

I thought Busybox was installed with the "root from scratch" stuff? I have it, but I had it before I rooted KitKat since I had rooted JB before KK. Are you sure it's not in /system/xbin? You may not be able to reinstall it, but is it already there?

As for r/w to /system, let me know if you find a solution. I haven't been able to figure out what the issue is. The "mount" command has been replaced with a script that isn't quite right, but that's only part of the issue.

Rooted System image?

To start I am knew to rooting so I apologize for my ignorance. I got my system image by extracting it from my tablet with the toolkit. However when I went to root my device it referenced a pre-rooted system image. Did I miss something? Any help would be greatly appreciated.

I am also curious how to root from scratch. This is what I am trying to do but I did not see the option in the toolkit.
[Android Q&A, Help & Troubleshooting] renojim:
I believe you can find pre-rooted system images for most (all?) of the supported tablets at the beginning of the Toolkit thread (or somewhere in the thread).

To root from scratch (recommended), you have to use Linux. There are "Live CDs" you can download and burn to a CD or USB flash drive. You then boot from the CD or flash drive. I'm sure there are plenty of tutorials around if you search. Root from scratch will pull the image from your tablet (just as you have already done), root it, and then copy it back. If you're unable to use that method for some reason, you'll have to find a pre-rooted image.

[Android Q&A, Help & Troubleshooting] Tyfighter98:
Thanks I will give it a look

---------- Post added at 03:20 AM ---------- Previous post was at 03:13 AM ----------

One more question as well. How do you know what system image you are running?
[Android Q&A, Help & Troubleshooting] renojim:
The "Image version" is given on the "About tablet" page under Settings. It should be something like "Acer_AV0K0_A1-810_RV0HRC03_PA_CUS1" (I have an A1-810). In glancing at the toolkit thread, it looks like the image version often gets abbreviated to just the RVxxxx_XX_XXX part.

It also looks like the first page may not always get updated with links to rooted images and it's quite possible that there isn't always one available. You may have to search through the thread to see if you can find a link to the one you need. It may be easier to figure out the Linux root from scratch method.

BusyBox?

I just rooted my Acer Iconia A1 810 running Kit Kat 4.4.2 but can't seem to install busybox. Has anyone else experience this? Also has anyone gotten Link2SD to work. I created a second partition but I keep getting a mount scrip error?
[Android Q&A, Help & Troubleshooting] renojim:
Someone above said the same thing about busybox and I told him I thought busybox was installed with the "root from scratch" stuff. He never replied. So... I would first check to see if it's already there before you try to install it.

I think the problem with Link2SD (and btw, that's one of the main reasons I wanted to root my tablet) is that it can't create its script on /system. Thus far I haven't found a way around the unable to mount /system rw, but I'm still making my way through the very long Toolkit thread. One of the things I wanted to try is to save /system to system.img, mount it as a loop device, manually add the Link2SD script, and then copy the modified system.img back to /system. I probably won't get a chance to try it for a while, but here's some stuff to get you started if you'd like to try. I assume you already have a microSD card inserted which will show up in /storage/sdcard1.

First create a directory in /storage/sdcard1. I called it sysimg (make sure you're root first):

su
mkdir /storage/sdcard1/sysimg

Here's the commands to save /system to /storage/sdcard1/sysimg/system.img (this is for an A1-810; some of the numbers would have to change for other tablets):

dd if=/dev/block/mmcblk0 of=/storage/sdcard1/sysimg/system.img bs=4096 skip=17664 count=262144

Here's the command to mount it. First create a directory to use for the mount. I used /data/local/mnt:

mkdir /data/local/mnt
busybox mount -o loop -t ext4 /storage/sdcard1/sysimg/system.img /data/local/mnt
cd /data/local/mnt

Now you should be able to change or add anything you want. One of the first things I did was to change the hosts file in /etc to a symbolic link to /data/local/hosts so I could use the MoaAB hosts file. I can now also edit the hosts file at will without having to constantly save and restore a system image.

From another tablet, I believe the Link2SD script goes in /system/etc (or /data/local/mnt/etc once it's mounted) and is called 'install-recovery.sh':

#!/system/bin/sh
#added by link2sd
sleep 2

#mount -t vfat -o rw /dev/block/vold/179:10 /data/sdext2 1>>$LOG 2>>$LOG
mount -t vfat -o rw /dev/block/vold/179:13 /data/sdext2

#mount -t vfat -o rw /dev/block/mmcblk1p5 /data/sdext2 1>>$LOG 2>>$LOG
mount -t vfat -o rw /dev/block/mmcblk1p5 /data/sdext2

#mount >> $LOG
#echo "$(date) mount finished" >> $LOG

I have a strong feeling that some of that may have to be modified for our tablet, but at least it's a place to start. I also don't know if Link2SD needs continual write access to /system, but I suspect it doesn't.

To save any modifications to the system image back to /system:

busybox umount /data/local/mnt
dd if=/storage/sdcard1/sysimg/system.img of=/dev/block/mmcblk0 bs=4096 seek=17664 count=262144

Then reboot.

Of course I take no responsibility if you muck something up in /system and then your tablet won't boot. :D

Let me know if you have the cojones to try this. I've done the save/modify/restore thing a few times, so I'm pretty confident about the above commands.

-JT
[Android Q&A, Help & Troubleshooting] Tyfighter98:

Well you're the second person to report that busybox wasn't installed. I had it installed when I rooted JB, so maybe the KK toolkit is messed up? I'll take a look at the scripts and see if I can figure out what's going on. You can open a terminal window and type 'su' and get the # prompt, right?

At first glance, it appears that busybox should have been installed in /system/xbin, but I don't see where that directory is ever created. I already had busybox in that directory since I had rooted JB. Can you check to see if the /system/xbin directory exists?

A1-810 KK

renojim, with a file manager I went to see in /system/xbin and /system/bin to check if it was present Busybox. No, not there.

Tyfighter98 and renojim, I managed to install busybox, although I do not understand I'll explain the procedure that I followed.

1) I ran the "Root from scratch" with the toolkit "Acer Iconia v0.9.4" (search on Google "androidiani GUIDA ROOT FROM SCRATCH", I can't post outside links), installing SuperSU when required and not Xposed installer: over the procedure, according to Root Checker the tablet had the root but I fail to install Busybox because I didn't have permission on /system;

2) I tried to unlock the bootloader following "Unlock Bootloader/Preloader + Flash CWM Guide by [MENTION=5889030]FireDiamond[/MENTION]"; the tablet went into bootloop, so I had to run the recovery procedure in that guide; I lost the root obtained;

3) I re-ran the Root from scratch, this time installing, when required, Superuser instead of SuperSU: as 1) I had the root, busybox did not install and I did not have the permissions on /system;

4) I followed the guide "how to easily unlock bootloader and root acer iconia a1-810 tablet with android kitkat 4.4.2" (search on Google) to the point 19.3 to try to unlock the bootloader, the procedure was completed successfully but was installed only CWM;

5) Again Root from scratch, installing SuperSU AND Xposed installer: the installation of Busybox was inexplicably completed successfully, I checked with a file manager and it is really present in /system/xbin.

IMPORTANT: I don't remember if I've done before step 4) or 5), I'm sorry but the memories of that afternoon are confused :)

Sorry for my English
