Do I lose any data or apps after swapping internal 2 external?

And one more question, I rooted my iconia a1 and is it risky to swap internal to external, I mean is there a possibility to brick the device?

Acer iconia B1-A71 boot

Hello Guys

I'm really in a very bad situation. This morning, I rooted my tablet Acer Iconia B1-A71. After that, I install Chainfire 3D and I tried to install the Chainfire driver so I can use this application. However, when the tablet rebooted, the screen was blocked on the acer logo !! I tried to reboot but it still the same result :(

I hope that someone can help me to fix this problem because I have no Acer after sale service in my country !

Ps: I tried to boot with two custom roms that i found on the net, but I had the same result on the recovery menu ("installation aborted")

Sorry for my bad english.

Thx.
[Miscellaneous Android Development] @non4:
Chainfire 3D is incompatible with jellybean. Find a stock ROM and install it. As for installation aborted you will need custom recovery to flash a custom rom

I believe it was caused by a mismatched version of the system.img.gz I downloaded from the Acer Iconia B1-710 / B1-A710 Downloads section differing from what was actually on my tablet.
[Miscellaneous Android Development] elmkzgirxp:
One thing may fix your bootloop. And that is to update your firmware. But since there are no available updates for now, I recommend you to send your device back.

I emailed Acer if I can gain access to a site where we can find all the downloads available which can't be found on the Acer website. I'm still waiting for their reply.

Acer is giving headache. We cannot update to 05 or 06 because of "Invalid partition setting" error. Check Acer's forum, many are complaining but no solution yet.

We can only use this tool if we are on 05 or 06 version, otherwise, you will be stuck in boot loop as what I have read.
[Miscellaneous Android Development] entonjackson:
A linux vm only makes sense if you can pass through tablet over usb to your vm. i don't have experience on this, but if that works i can help you.

just set up your vm, i would recommend ubuntu. when everythings set up, open a terminal, cd to toolkit directory. then do:

chmod +x toolkit
sudo ./toolkit

then apply "Root from scratch".

good luck and ask, if there are open questions.

Just use a Linux live disto as mentioned earlier, Ubuntu, fedora, knoppix etc.

Download a CD or DVD and have a play, its quite cool not even needing a hard drive and useful to fix your PC when win doze takes a dive.

su binary not found after completed rooting

I've used the toolkit provided and everything went smoothly until I've rebooted and tried to install Superuser from the play store. But unfortunately i couldn't get it work and couldn't gain root access because i found out that the su binary is not found in my device and i don't know what to do now. How can i get the su binary actually? have googled about it but i just couldnt find the zip file or the appropriate file to make it work. I also used SU update fixer but it says that fix failed. try dowloading and flashing an update.zip from andriodsu.com How can i fix this? thank you very much.

[Miscellaneous Android Development] al2go77:
Are you using an A1-810? I've experienced something similar when trying to root my tablet (from Ubuntu, root from scratch). The toolkit reported a successful operation but after rebooting I had no root access in superuser. To get it to work I had to copy some files from sodaFR's system image (see first post of this thread, be careful with the version you use to avoid a bootloop) to my system image and use the toolkit again to apply the image. The changed files are mostly in /system/bin and /system/xbin but also in /system/app to get SuperSu since this method is incompatible with superuser, you must also remove the su binaries initially copied by the toolkit. Be careful also to properly copy busybox and all the symbolic links under /system/xbin and not to install another busybox instance.
[Miscellaneous Android Development] wbrambley:
I think any pre rooted img that is not the same version as on the tablet will result in problems. Root from scratch pulls the IMG from your tablet so you can't make this error.

If you have rooted from scratch an IMG not listed here please upload and post here to help others.

Asus Memo Pad HD7 compability

Hello folks, I am about to purchase an Asus Memo Pad HD7 and have been doing some research regarding root, rom backup, etc.

I have discovered that the Memo Pad HD7 shares almost the same specs as the Iconia A1 (CPU, GPU, RAM are the same). My question is, can the Acer Iconia Toolkit be used on the Memo Pad HD7?

What does swapping mean? Does it mean using external instead of internal sd card for installing apps or does it mean changing datas?

Second question. I swapped and ı couldn't see external sd card in the file manager and pc. Internal sd card was there and nothing had changed:confused: Then i swapped again and everything has become what they were, before swapping.

SuperSU update fails

After using the toolkit (from Ubuntu - root from scratch) on my A1-810 but ending up with the /system RW problem, I used this method based on sodaFR's fix. This time it worked but I was missing many functions (couldn't replace the hosts file for instance to get Adaway to work). It turned out I was missing busybox and all the simlinks under /system/xbin. So I copied them all (cp -av) from sodaFR's image and reapplied the image and it fixed it.

I'm left with one residual problem: The SuperSU app provided in sodaFR's image works fine but now Google Play wants me to apply a SuperSU update. If I do, then SuperSU says it needs to update its binary file, downloads it but fails to install it and quits. The only way to get SuperSU to work again is to uninstall the Google Play update. Is anyone else getting this problem? Until I can find a way to fix this I cannot autoupdate my apps nor use the "update all" function in Google Play which is annoying. Or is there a way to permanently exclude an app from updating?

Thanks.

Root or not root that is the question

Hi,

I did the "root from scratch" on an Ubuntu OS to root my tablet.

Image Version on my tablet is: Acer_AV052_A1-810_1.077.00_WW_GEN1

The last message from the toolkit was:

> SUCCESS!

> Your Acer Iconia A1-810 is now rooted. Unplug your tablet and reboot.

> Install Superuser from the Google Play Store and have fun ;)

- Superuser installed

- Root tested with "Root Checker Basic" but I got the message "Sorry! This device does not have proper root access"

- I installed the app "Check ROOT" and is said: "YES" = rooted

Titanium Backup doesn't work. message: "no root"

The su file exists: /system/bin/su with "-rwsr-sr-x"

What can I do?

Thanks for help!

No risk to brick. But some said swap doesn't really work on the a1, which i don't know why and cannot debug also.

try it out and let me know.

It seems I have to add Windows 8 compatibility.

Could you please do me a favor, download python 2.7 and start a python shell.

enter the following:

import os
print os.name

and post the output here.

apparently they changed this name in windows 8

Most certainly no. But you can change this ;)

Look for a file called dumchar_info in /proc directory of your tablet. use ES File Explorer or any other fileexplorer to see the content. Or use ADB.

Post the content here.

what have you done before?

you must do: sudo ./toolkit.sh

Actually i came back yesterday from vacation ;)

Swapping for which device?

Please check this post.

Sorry for the bad support A1 owners. I don't own an A1 myself. If you want to improve the process of the toolkit, please tell me which files need to be copied to which directories. And what needs to be done if e.g. SuperSU is getting an update.

Come on, this has nothing to do with being a Noob or not.

How could you not read it? It's written in big fat red letters.

I got root access!

Hello,

It worked with application "Superuser with a white hash in the blue icon"!

With the first start I got the message "superuser bin file" needs an update

Two options:

Method: "Install" failed

Method: "Recovery" seems to work - because after that...

- Root check Basic said "This device has root access"

- Application "Check ROOT" said "phone is rooted"

- DroidWall could activate the firewall which required "root"

- and Titanium Backup also works now with root

But when I start Superuser again

still the same message "superuser bin file" needs an update

I cancelled the update task...

everything seems to be fine now. :victory:

Modification of the hosts file failed.

Hi,

it's me again :)

Did you try to update the "old" su-binary with recovery mode a second time, to get ride of the wrong message "su-file is still too old"?

Do you use AdAway?

The program failed to update the hosts-file.

Other tools with "root" right failed, too.

E.g. the total commander app tried to remount the filesystem /system as "read/write" - but the following command failed:

> mount -o remount,rw -t ext4 /emmc@android /system

Error message: "Failed: Operation not permitted"

So total commander couldn't modify the hostsfile in /etc/hosts

Do you or someone else have a solution?

Acer Taiwan just release A1-810 ROM in their support site ths week.

http://www.acer.com.tw/ac/zh/TW/content/drivers/4756;-;A1-810

It's TWN_GEN1 version ROM, if you brick your A1-810, maybe you can try to flash this from SD card before sending it back to Acer.

And they also release the kernel source AGAIN (same file name as before, but the content is different), I can use this one to build a workable exfat.ko (from exfat-nofus), but I can't do it for the old kernel source tarball.

Unfortunately, even we can build exfat.ko for A1, but the vold using in A1 don't support.... you cat mount exfat yourself, but it not show in vold.
