so i downloaded the firmwire version RV21RC02_WW_GEN1:

i place the image at system_image

then using toolkit it says no system.img.gz in folder system_image

using windows step..
[Miscellaneous Android Development] 888jonathan:
- @ 888Jhonathan - in step 5, the fist line references system.img.GZ and the the example doesn't have the .GZ at the end. I would suguest removing the .GZ from the fist line so it won't be confusing to us Linux challenged. :confused:

Sorry about this mistake, I've edited it to system.img. :good:

Thanks a lot for your tests, I really appreciate that. It's nice that you have your tablet rooted now. :laugh:
[Miscellaneous Android Development] xxiteruxx:
Hi, I also got the same problem that foruma has. I successfully rooted my B1-A71 using the toolkit and I also tried swapping the internal and external storage, and though the toolkit said it was successful, I saw that my storage space was unchanged. I checked /etc like you mentioned, and there's both a vold.fstab and a vold,fstab.nand in there. Hope you can help us out. Thanks!
[Miscellaneous Android Development] foruma:
Hi Enton,

Yes, it has both files in the /etc folder. I have save a copy of the files in my SD card, will use pc to edit it and paste the contents for your perusal later.

Thanks again.
[Miscellaneous Android Development] treetop777:
Unfortunetly, most likely you will not be able to recover from that. If you can't get into the factory reset (Vol Up + Power - I THINK) then it's hopeless. Even if you had a good image, the toolkit can no longer communicate with the tablet. Sorry.

Can you let us know what method did you use?
[Miscellaneous Android Development] Ollemedo:
I just followed the windows steps to root my iconia. I used the RV03RC08 System.img.gz when I rooted the device.

I have tried too factory reset the device but it still just stuck in the boot loop. Any tips what to do next, I´m kinda stuck atm.
[Miscellaneous Android Development] treetop777:
There is no backdoor recovery for it so there is nothing you can do. I hope you bought it from Amazon.

Has anyone tried to root a1-810 with 0.7.6 from scratch?
[Miscellaneous Android Development] old_art:
does any 1 manage to root their a1-810???

i dont see someone successfully rooted their a1-810 and it makes me scared to root it.. because im a student and it is expensive to me to buy a new one if my device brick...

i saw all the a1-810 user in the end bricked their device...

hmm...i want to root my a1-810 =(
[Miscellaneous Android Development] entonjackson:
of course you cannot see, because you don't read.
[Miscellaneous Android Development] aldolo:
i'm waiting too. the failure/success ratio seem to high right now. moreover i hope for the 4.3 update before trying the root. let's cross the fingers.
[Miscellaneous Android Development] treetop777:
0.7.6 is untested so far; you are welcome to try at your own risk ofcourse. The A1 can be rooted however, look at post 1843 and then 2044.
[Miscellaneous Android Development] 3r1clfbo:
Hi Enton,

First of all, thank you so much for your toolkit:good:! Rooting my little princess' Acer Iconia B1-710 8GB was so straight forward.

I then tried to swap internal and external sd (8GB and 32GB) and I seem to be in the same situation as foruma. both vold.fstab files are the same as those he/she posted. And when restarting the tablet, the swap does not seem to have taken place: apps still on small internal sd.

I will be watching this thread for your updates!

Cheers

Eric

Hy everybody! I've maked root on a1-810 (0.7.4 root from scratch + RW workaround) and root validator shows all 5 items green and root explorer works fine BUT titanium backup and sd maid not uninstalling apps! What's wrong?
[Miscellaneous Android Development] treetop777:
Did you follow the instructions on post 1843? Because if you didn't, 0.7.4 don't always work right to root the A1. If you have the courage, try (at your own risk) 0.7.6 which has the R/W workaround built-in.

EDIT: I rooted my A1 (post 1843) and just tested Titanium back-up and it did uninstall Mcaffee for me.
[Miscellaneous Android Development] citynomad1:
Iconia B1-710 in bootloop after rooting

I just rooted my B1-710 using the toolkit and the pre-rooted image (the correct one for this model - I checked twice!) and now the poor tablet is in bootloop. The rooting process completed successfully, didn't display any error messages, told me that the device is now rooted and that I can unplug it, etc.

In case it makes a difference, I ran the toolkit from Windows, and the tablet is the 16GB model.

Any ideas?
[Miscellaneous Android Development] vadison:
Yes, i did all instructions step-by-step in post 1843 and in your post 2044!

Now I have fixed titanium by switching on "Use system busybox" in the settings! But Adaway don't work=( I think it's becasue busybox's files is in "xbin" folder, not in "bin".. Am I right? And can i just cut they off from "xbin" and put in "bin"?
[Miscellaneous Android Development] xxiteruxx:
Uhm, not to tell you what to do or anything, but why not just use the latest version of the toolkit on the first page? it worked fine when I rooted my B1-A71. Wala naman ako naging problema. :D
[Miscellaneous Android Development] vadison:
Oh, i have noticed, that there are TWO su files - one of them in "bin" folder, and other is in "xbin" folder and they have different size. Same with busybox files. WHY?
[Miscellaneous Android Development] entonjackson:
the one in bin is from the installed SuperSU app.

the one in xbin is copied by my toolkit.
[Miscellaneous Android Development] vadison:
wait wait wait wait wait,

1st. Superuser, not SuperSU, coz su.tgz (from manual) already consist Superuser.apk

2nd. If I get it right, we have: toolkit's root (with R/W bug) and after that - root with R/W workaround using su.tgz, that makes root second time, right? And there is two su and busybox files. And therefore titanium and adaway and other does not work properly, right? Which su and busybox i must delete?
[Miscellaneous Android Development] entonjackson:
wait wait wait.

which version did you use actually.
[Miscellaneous Android Development] vadison:
0.7.4
[Miscellaneous Android Development] entonjackson:
Then forget everything i said.

But i think you need SuperSu instead of Superuser.

Succesfully rooted B1 - 711

First it didn´t worked, and i figured out why it won´t work, if you´re native language is not english, turn System language to English(US) and be sure Swipe, Swiftkey or other Keyboards are unchecked, use the Android keyboard for the root methode. My dictionary corrects all english words to german, after i changed it all worked fine. :D

thx entonjackson great work :good: :laugh:
[Miscellaneous Android Development] entonjackson:
Which method did you choose to root?
[Miscellaneous Android Development] Rhodos:
i rooted it with Toolkit v0.7.6
[Miscellaneous Android Development] entonjackson:
Yeah but root from scratch or root from system.img.gz?
[Miscellaneous Android Development] Rhodos:
system.img.gz
[Miscellaneous Android Development] jbarcus81:
Says file can't be found.. I have downloaded system.img.gz for the Acer Iconia A1-810 ... Says some extra steps are needed ... I'm a little confused. Certainly not new to rooting devices, never rooted a tablet though. From what I am reading, I need the system image that matches my system which I have.. the toolkit.. right?
[Miscellaneous Android Development] citynomad1:
So, is there anything that can be done about this, or is this tablet permanently screwed now? And why did this happen?

Thanks for any help.
[Miscellaneous Android Development] treetop777:
That should be it. The right image and the toolkit.
[Miscellaneous Android Development] twu2:
0.7.6 root from scratch for A1, the su at xbin, but the toolkit will check it at bin (it will fail).

please move su from xbin to bin for a1 in toolkit.

And, it use clockworkmod's Superuser app and su, I think the version in this toolkit is not newest one, you can get the current version from here:

http://download.clockworkmod.com/superuser/superuser.zip
[Miscellaneous Android Development] entonjackson:
I didn't modify the structure of the workaround.
[Miscellaneous Android Development] twu2:
But, it the toolkit, it will check /bin/su after copy the file, it won't pass this check here.

The workaround don't care su put in /bin or /xbin, so you can move it from /xbin to /bin

try:
with open("/media/iconia/bin/su"):
print("Successfully mounted pulled system image.")
except IOError:
print("E: Couldn't unzip system.img.")
print("Cleaning up...")
subprocess.call("sudo umount /media/iconia", stdout=dev_null, shell=True)
subprocess.call("sudo rm -rf /media/iconia", stdout=dev_null, shell=True)
subprocess.call("rm system.img*", stdout=dev_null, shell=True)
wait_for_enter_exit_error()
[Miscellaneous Android Development] entonjackson:
ah i see. i will fix this.
[Miscellaneous Android Development] twu2:
Another problem in 0.7.6.

In the workaround, it use a lot symbolic links.

But in 0.7.6 zip, after extact it, it become a normal file, not symbolic links anymore (I test it under windows and linux, got same result).

I remember in 0.7.5, after unzip, they are still symbolic links.

This issue won't brick A1, but it won't root and, do some command will make A1 hang.

I think the better method is tar them together, and put the tarball in toolkit, then just extract them directly.

Here is the tarball make by me (include ClockworkMod's new Superuser.app and su binary):

[Miscellaneous Android Development] treetop777:
I don't remember if the tab would even go into the stock recovery once it's bootlooping. But along the same idea, we need somebody to work on a procedure to NvFlash or Fastboot an original image back to it. In that case, the first procedure for everybody would be to extract and save an original image from their tab own tab (which the toolkit can do now if I'm not mistaken) just in case. I suspect that even with an already rooted image from a year ago, the image in the tab TODAY won't be exactly the same and that's maybe why tabs are still being bricked..

Absent of that, i would suggest that people (if they can't afford to risk bricking the tab) use the root-from-scratch method and apply the R/W workaround manually. OR buy the tab from Amazon. :laugh:

Still same problem like v0.7.7, the root from scratch is not work for A1.

after unzip the toolkit, in v0.7.5, they are symbolic links, for example:

lrwxrwxrwx 1 root root 7 Oct 28 14:19 0.7.5/bin/a1/xbin/bzip2 -> busybox

but it v0.7.6 and v0.7.7, they are normal file:

If we use v0.7.6/v0.7.7 to do root from scratch, the workaround won't work, su exist, but command related to busybox are failed.... and the bad thing is, the mount command already be modified to a normal file (it was symbolic link to toolbox before root, and should be symbolic link to busybox), so if some program execute mount command, it might hang the machine...

Please fix it (I don't know how to zip symbolic links like v0.7.5, usually, we use tar to do this, tar won't convert the symbolic links to normal files.....)
