Updated OP with solution, many thanks to @fipsy for the final solution, here is his post for those that need help rooting this device: (UPDATE: Root for 4.2.2 at the end of the post)
Last week I investigated a lot of days to solve the problem: (I'm sorry for not being able to post working links in this forum because I didn't write enough here. :( So you have to reconstruct my links yourself into your browser)

As omegadrive supposed you just have to exchange the su binary, give the right permissions and the Superuser App from the Playstore will immediately work.

The necessary USB drivers for the device are found here: http://yadi.sk/d/54lX5c2O386XU

They only work with Windows 7!

After starting the "adb shell" you can gain root permissions on the device by typing "su". The su distributed with the device in /system/xbin is not compatible with common superuser apks. So it has to be exchanged with the version 3.1.1 binary: http://downloads.androidsu.com/superuser/su-bin-3.1.1-arm-signed.zip

Copy it to your /sdcard. Then continue with adb shell:

Code:
$ su
# cd /system/xbin

Mount the system partition read/write:

Code:
# mount -o remount,rw -t rfs /dev/block/st19 /system

Rename the original binary for later use (if something fails):

Code:
# mv su su-orig

Copy the binary to the xbin folder:

Code:
# busybox cp /sdcard/su ./su

Change the permissions:

Code:
# chmod 6755 su

Mount the system partition read-only and exit:

Code:
# mount -o remount,ro -t rfs /dev/block/st19 /system
# exit
$ exit

Now install the Superuser App from the Playstore - and have fun! Do *NOT* Update the su binary from within the Superuser App or it will be overwritten with a non-working version!

Cheers, Volker

CUSTOM RECOVERY FINALLY POSSIBLE!!! Again, many thanks to @fipsy, here is his post:
I finally made it! :laugh: Here is a working CWM Recovery for the HANNspree HANNSpad SN1AT71 (HSG1279).

I didn't fully test it but the backup function works. Also mounting and unmounting partitions works as well as the adb shell which is very important if the device is bricked and doesn't boot anymore.
Before connecting to the device via adb shell it is necessary to mount the /system partition (menu "mounts and storage") because otherwise /system/bin/sh cannot be found by adb shell.

The CWM recovery by default stores it's backups on the external SD-Card. The benefit is that the backup can easily be plugged out and stored apart from the device. But the recovery is also able to restore backups from the internal sdcard. Those backups can be made online on a running android system by using apps like "Online Nandroid Backup" and "Nandroid Manager". The benefit is that it's not necessary to reboot the device before backing up and you can keep on working.

There is one problem when creating backups in CWM Recovery: The date/time of the backup is always set to 1st of January 1970 due to a missing backup battery in this device. Look here: http://tau.shadowchild.nl/attn1/?p=341. So if you want to make backups with accurate timestamps you would have to set the actual time of the device using adb shell: Start adb shell and enter:

Code:
/system/xbin/busybox date -s "YYYY-MM-DD hh:mm:ss"

before making the backup.

To cut a long story short: Download the CWM-Recovery here: http://yadi.sk/d/ArprqzfFFWvy4 and flash it to your (rooted) device. How to do this:

  • Copy the file cwm-recovery.ima to your internal sdcard.
  • Either connect via adb shell and enter su
  • or run a Terminal Emulator and enter su
  • then enter
    Code:
    cat /sdcard/cwm-recovery.ima > /dev/block/acta
and you're done! Have fun! Comments are appreciated!
Perhaps someone likes to create an update.zip from it?

Edit (01/28/2014): There is a new version 6.0.3.3. Look here: http://forum.xda-developers.com/showpost.php?p=49835135&postcount=283
Edit (05/04/2014): There is a new version 6.0.3.3.a. Look here: http://forum.xda-developers.com/showpost.php?p=52416205&postcount=492

ROOT for new OTA 4.2.2 update:
Good news for germany: The rollout began tonight! I just got the update to Android 4.2.2! :laugh:

Some people asked for the upgrade file to manually update from the recovery. Here it is: http://yadi.sk/d/igsBGsAjFpLsL
Edit (01/13/2014): Seems this update only works on devices with special G-Sensor hardware (KIONIX 3-axis Accelerometer).

@ig6677: There you will also find the META-INF you wanted.

For your information: After my update to Android 4.2.2 root has gone on my device! I expected this. All Apps that need root don't work anymore. I don't know what you did that root was still there after the update...

Furthermore in /system/xbin there is no su file anymore. Also my CWM Recovery has gone and was replaced by the Stock HANNspree recovery!

But whats new: If you connect to the device via adb shell you immediately have superuser rights! No su is needed for this anymore. So it's possible to restore the CWM Recovery using cat.

If you adb push the 3.1.1 su binary from your pc to the /sdcard on your device and after this execute my commands in the first posting of this thread the apps have su rights with superuser.apk again. But you will not be able to add new programs to the superuser app (if a new app requests superuser rights there is no popup). So this is no solution.

The Superuser App is not able to grant superuser rights on android systems > 4.1.1, but the App SuperSu is! So download the SuperSU ZIP from here: http://download.chainfire.eu/351/SuperSU/UPDATE-SuperSU-v1.65.zip

Then copy it to your sdcard and install it using the Recovery. Voila! Everything works again!

Another issue: The Huawei E1750 Surfstick is not detected anymore. On 4.1.1 it was no problem to surf using this stick. But I think this is one of the "great features" of the new android versions...

New recovery version!
:victory: Here it is: The new version 6.0.3.3 of CWM Recovery for the HANNspree HANNSpad SN1AT71 (HSG1279)

Beside some minor bugfixes the main benefit of this release is that there are no more errors when trying to restore the .android_secure folder. So the "dirty" workaround to restore this folder is not necessary anymore.

The .android_secure folder is also automatically restored together with the data partition when selecting "data" from the "advanced restore" options.

http://yadi.sk/d/OmsYk6TIGsBsB

Information on how to install you will find here: http://forum.xda-developers.com/showpost.php?p=49166546&postcount=133

Cheers, Volker

My original question:
Just bought this tablet on Cybermonday for a really good price, but can't find a way to root it for the life of me...
Main problem has been I can't see it using ADB (v1.0.31), always list no devices even with the latest generic Google ADB driver, which shows fine on device manager.
Tablet comes with Android 4.1.1 and no extras, is just a plain version of android with Play market and ES File Explorer pre installed and have access to android stock recovery.

Any ideas?

Also, just in case I start messing with the tablet, Any way I can backup the stock system just in case?

Thanks.

Update:
More info on the tablet...
Model name: SN1AT71
Hardware (According to CPU-Z): gs702a
Board: full_gs702a

Help me

I pressed the power button for twenty seconds thhen released it a few times. It eventually woke up.
Great it worked can you guide how to use adb or some thing to bring this back to original stock I try the pad tools using original updated files but it give a file size too big error.. Adb gives me unauthorized device...



**Update I Tried using Pad Product Tool. And it times out???? Tried three times no success?

Maybe it's good it timed out. There is always quite a lot of small details to be learned with any tools.

Why on the earth you are pushing some "Catpain" firmware into it, not those I said?
Also if you erase the flash, you select them all, boot, rec, misc, system and do the formats too...
You can go straight to the adfu mode by starting it pushing power and vol+ at the same time.

So, what works in that thing? CWM? System? Obviously some that gave you those two udisks anyway...

.. Adb gives me unauthorized device...

Unauthorized device means that you need to go to the tablet screen and authorize your PC to use ADB, at least in my experience. Does "adb devices" return an alphanumeric string, then "unauthorized device"? If so you are booted into Android system and should see a dialog box on the screen. If you have @fipsy's CWM installed you might also try booting into that and then using ADB.

I think the second biggest flaw with this tablet is the tiny emmc storage. I have to remove a lot of original android apps and move some to internal storage to make space for new apps. If only there was a way to repartition it so that we had a lot more space. I've tried moving the apps that boot up with the OS but when they get moved they no longer load up upon OS bootup. The first flas being the horribly slow CPU. My Galaxy Tab 4 has a 1.2GHz CPU and its a whole lot faster than this thing. Comparing the two it would be hard to believe that the two tablets have a quad core 1.2GHz CPU because this thing is so slow.

@ CXZ : is there a way to mount data_bak in recovery. Flipsy's CWM refuses to mount data_bak and I need to wipe it because after installing your PAD tools rom whenever I install an OS now I am getting some japanese apps installed too even after completely wiping the tablet and installing different ROM's. Also the portable TWRP no longer works with my tablet. It could be because I have the latest official rom installed. I will test again later with an older official rom. When I flash the portable recoveries it doesn't create the *.ko and *.ok files. I'm not sure where to get the files from the rom I am using.

I have done quite a bit work for re-partitioning these atm7029s before found the PAD modify tool. So, using it just open the "partitions" and change the value.
My tools can be used before or during flashing using PAD Product tool. They can be found from my signature or here also from donation button (for those who
are not member here).

Usually you can just leave that vendor.img unflashed and the Chinese apps are gone. If they are on that data_bak just do the same to it.

I'll have to check that new recovery closer some day... But in the mean time you probably can just use an earlier rec.img, although mixing firmwares
sometimes causes problems. Not big ones if same android versions, but have to do some fine tuning then.

I've used the PAD modify tool to edit the partition but the partition never resized for me.

I don't use the pad tool to flash OAKP or Cyanogenmod because my efforts to use different roms other than those you posted a link to failed. Every time I try to use a different rom other than what you've linked to I got a blank screen after the Hannspree LOGO. This also happens if I try to install Christian Troys Rom's using the latest official T71 rom (20140515E) as a base for the Christian Troy roms. I can not figure out why the newest rom (20140515E) wont work and the older one (update-FW8963-20131219E) does

Still, they are Actions' "PAD whatever tools". Not mine at all. I don't want to take or get credit from something that I have not done!
(but maybe I should, as it seems to be just okay here, IDK). So, please, leave that "your" word away from Actions' tools for now on...
Thanks for understanding! :good:

Okay, back to business...

I haven't actually tested that partition size thing. It's output should be just some hex values in a bin file. So, I have just assumed it should work...
If not, test the tools I mention in my signature/blog.,,

Yes, PAD product tool doesn't work with CM and such. To make it work you can dump the partitions either by using adb/terminal or just
use the JollyDumper2 package of mine. Extract and read the instructions before using...

And, yes I really have to check that new firmware... ( just for curiosity, not that it would help in any way...)
It's sad that Ainol hasn't released any updates since that 2014-01-04 (yyyy-mm-dd) firmware...

> your pad tool
Thanks, I see that you removed that word already. :good:
Getting credit is always nice, maybe too nice for some, but one can then also get the blame if something goes wrong.
And that situations isn't that nice, especially when you cannot really do any fixes and such....

I tested TWRP portable now using that new stock recovery. For me it worked as expected.... odd.

If you have saved the previously created *.ko and *.ok files, just use them, they are the same.
Otherwise you can use for example 7-zip (i use latest beta) and dig the touch driver from the sn1at71.zip.
sn1at71.zip -> misc.img -> modules -> ctp_gslX680.ko --> rename to TWRP-portable.ko --> copy to sd card

I don't have as muck time as did but I was going to do this when I get the time. Thank you for the help though.

Quick question: I assume the newer firmware is rootable, which method? Or is it possible to tell CWM to block over-writing Recovery, and then just flash SuperSU?

Oh yes, and can this TWRP-portable be installed permanently? What version is it based on?

I've installed a working AOKP 4.2 to my Hannspree Hannspad HSG1279 T71 (Rotation and wifi works perfectly for me) and backed it up in CWM. Its RAR'ed and all you have to do is unpack it to your SD card then do a system restore. Put the backup I've uploaded into the sd card and wipe your tablet then do a restore in cwm.

If you plan on reuploading this please give credit to the original sources.

All credit goes to

Christian Troy on SlateDroid for his original AOKP http://www.slatedroid.com/topic/91865-custom-rom-aokp-422-by-christiantroy/
cxz on SlateDroid for his Boot2CT's Boot Converter http://www.slatedroid.com/topic/102857-compatibility-zip-maker-and-cwm-recovery-maker/ and for his help with porting the rom.

Please give credit to the original sources if you are to reupload this.

Here is the download link for the AOKP Backup

If your tablet is already rooted just do a wipe of the tablet and install the newest firmware and it will be rooted. All you have to do is install SuperSU. No TWRP portable won't be permenently installed.

@steve30x : Oh yes. The portable recoveries testing you did at Slatedroid. Did you also test the permanentizer using a stock recovery as the base?
It's possible that the permanentizer failed for you because not using the stock. That is why I've added "warning" now that they should be used on the stock,

@kevinthefixer : So IMO it should be possible to permanenetize those portables, but to be sure someone just must do the testing.
It is TWRP v2.6.3.0 made by Christian Troy : http://www.slatedroid.com/topic/91617-custom-recovery-twrp-v2630/

Not yet. I will test it within the next few days. I might have time to do so tomorrow.

Anyway I was reading this thread found that the tablet was not boosting to 1.2GHz and was not going above 1.08GHz so I followed the instructions in this post to make the tablet boost to 1.2GHz.

http://forum.xda-developers.com/showpost.php?p=50809393&postcount=391

You will need to download the latest Kernel Tuner for it to work. It makes a big difference to the performance of the tablet. What we need now is some way of overclocking the CPU slightly (even 1.3 or 1.4GHz would make a big difference)

So no way it has support for f2fs. Not a big deal at this point because as far as I know none of the custom ROMs that Steve30x has put together support f2fs either. But I would expect a significant performance increase from that.

It's going to be at least a couple weeks before I can test anything, I must force myself to do my taxes.

Ah, the old "Kernel Tuner" trick... Have you tested it using 4.22? At some point KT didn't support 4.22 without doing some "hacking".
Because of that I made recovery flashable package called JustBoost. It only enables the same basic Android "feature" that the Kernel Tuner does.
You can find a link for it from my signature/donate button/blog...

Funny that in some threads at Russian 4pda forum this my little zip has another "developer" name. Not because of classical childish stealing. .
No, in this case because some half brain idiot who worships that developer included his name to it when releasing it (without asking of course).

    # mount -o remount,rw -t rfs /dev/block/st19 /system

    Rename the original binary for later use (if something fails):

    Code:
    # mv su su-orig

    Copy the binary to the xbin folder:

    Code:
    # busybox cp /sdcard/su ./su

    Change the permissions:

    Code:
    # chmod 6755 su

    Mount the system partition read-only and exit:

    Code:
    # mount -o remount,ro -t rfs /dev/block/st19 /system
    # exit
    $ exit

    Now install the Superuser App from the Playstore - and have fun! Do *NOT* Update the su binary from within the Superuser App or it will be overwritten with a non-working version!

    CUSTOM RECOVERY FINALLY POSSIBLE!!! Again, many thanks to @fipsy, here is his post:
    I finally made it! :laugh: Here is a working CWM Recovery for the HANNspree HANNSpad SN1AT71 (HSG1279).

    I didn't fully test it but the backup function works. Also mounting and unmounting partitions works as well as the adb shell which is very important if the device is bricked and doesn't boot anymore.
    Before connecting to the device via adb shell it is necessary to mount the /system partition (menu "mounts and storage") because otherwise /system/bin/sh cannot be found by adb shell.

    The CWM recovery by default stores it's backups on the external SD-Card. The benefit is that the backup can easily be plugged out and stored apart from the device. But the recovery is also able to restore backups from the internal sdcard. Those backups can be made online on a running android system by using apps like "Online Nandroid Backup" and "Nandroid Manager". The benefit is that it's not necessary to reboot the device before backing up and you can keep on working.

    There is one problem when creating backups in CWM Recovery: The date/time of the backup is always set to 1st of January 1970 due to a missing backup battery in this device. Look here: http://tau.shadowchild.nl/attn1/?p=341. So if you want to make backups with accurate timestamps you would have to set the actual time of the device using adb shell: Start adb shell and enter:

    Code:
    /system/xbin/busybox date -s "YYYY-MM-DD hh:mm:ss"

    before making the backup.

    To cut a long story short: Download the CWM-Recovery here: http://yadi.sk/d/ArprqzfFFWvy4 and flash it to your (rooted) device. How to do this:

    • Copy the file cwm-recovery.ima to your internal sdcard.
    • Either connect via adb shell and enter su
    • or run a Terminal Emulator and enter su
    • then enter
      Code:
      cat /sdcard/cwm-recovery.ima > /dev/block/acta
    and you're done! Have fun! Comments are appreciated!
    Perhaps someone likes to create an update.zip from it?

    Edit (01/28/2014): There is a new version 6.0.3.3. Look here: http://forum.xda-developers.com/showpost.php?p=49835135&postcount=283
    Edit (05/04/2014): There is a new version 6.0.3.3.a. Look here: http://forum.xda-developers.com/showpost.php?p=52416205&postcount=492

    ROOT for new OTA 4.2.2 update:
    Good news for germany: The rollout began tonight! I just got the update to Android 4.2.2! :laugh:

    Some people asked for the upgrade file to manually update from the recovery. Here it is: http://yadi.sk/d/igsBGsAjFpLsL
    Edit (01/13/2014): Seems this update only works on devices with special G-Sensor hardware (KIONIX 3-axis Accelerometer).

    @ig6677: There you will also find the META-INF you wanted.

    For your information: After my update to Android 4.2.2 root has gone on my device! I expected this. All Apps that need root don't work anymore. I don't know what you did that root was still there after the update...

    Furthermore in /system/xbin there is no su file anymore. Also my CWM Recovery has gone and was replaced by the Stock HANNspree recovery!

    But whats new: If you connect to the device via adb shell you immediately have superuser rights! No su is needed for this anymore. So it's possible to restore the CWM Recovery using cat.

    If you adb push the 3.1.1 su binary from your pc to the /sdcard on your device and after this execute my commands in the first posting of this thread the apps have su rights with superuser.apk again. But you will not be able to add new programs to the superuser app (if a new app requests superuser rights there is no popup). So this is no solution.

    The Superuser App is not able to grant superuser rights on android systems > 4.1.1, but the App SuperSu is! So download the SuperSU ZIP from here: http://download.chainfire.eu/351/SuperSU/UPDATE-SuperSU-v1.65.zip

    Then copy it to your sdcard and install it using the Recovery. Voila! Everything works again!

    Another issue: The Huawei E1750 Surfstick is not detected anymore. On 4.1.1 it was no problem to surf using this stick. But I think this is one of the "great features" of the new android versions...

    New recovery version!
    :victory: Here it is: The new version 6.0.3.3 of CWM Recovery for the HANNspree HANNSpad SN1AT71 (HSG1279)

    Beside some minor bugfixes the main benefit of this release is that there are no more errors when trying to restore the .android_secure folder. So the "dirty" workaround to restore this folder is not necessary anymore.

    The .android_secure folder is also automatically restored together with the data partition when selecting "data" from the "advanced restore" options.

    My original question:
    Just bought this tablet on Cybermonday for a really good price, but can't find a way to root it for the life of me...
    Main problem has been I can't see it using ADB (v1.0.31), always list no devices even with the latest generic Google ADB driver, which shows fine on device manager.
    Tablet comes with Android 4.1.1 and no extras, is just a plain version of android with Play market and ES File Explorer pre installed and have access to android stock recovery.

    Any ideas?

    Also, just in case I start messing with the tablet, Any way I can backup the stock system just in case?

    Thanks.

    Update:
    More info on the tablet...
    Model name: SN1AT71
    Hardware (According to CPU-Z): gs702a
    Board: full_gs702a

    I have had the best luck with AOKP for a daily driver on this tablet. CM10 seemed to lag more than the stock ROM, and had some stability issues as well IIRC. Recommend you start reading on page 86 of this thread and read it through, don't just skim it.

    What ever you do to this tablet, it will always be a work mule, never a thoroughbred.
    Thanks for your reply, kevinthefixer. I have read this thread more throughly. Because things can be confusing and it's hard to gather all relevant information, I have created a small step-by-step guide how to replace stock ROM with Cyanogenmod 10.1. Here it is:

    1. Download BNMGUYs_CWM_based_recovery_v6.0.3.3_for_ATM7029_portable_[cxz].zip (see http://www.slatedroid.com/topic/107...e-versions-of-custom-recoveries-cwm-and-twrp/) and copy the zip file to a microSD card.
    2. Create a folder called clockworkmod on the microSD card with a backup folder inside that folder.
    3. Download CM10.1_Hannspad_T71.zip (see http://forum.xda-developers.com/showpost.php?p=58325450&postcount=854) and extract the folder CM10.1_Hannspad_T71 to clockwordmod/backup/ on the microSD card.
    4. Insert the microSD card in your tablet (tablet turned off).
    5. Press Vol- + Power button to boot the recovery system.
    6. Select "apply update from sdcard", then sd-ext and then BNMGUYs_CWM_based_recovery_v6.0.3.3_for_ATM7029_portable_[cxz].zip. This will boot CWM once without replacing the recovery partition.
    7. In CWM select "wipe data/factory reset" and confirm with Yes.
    8. After wiping the tablet select "backup and restore", then "restore" and "CM10.1_Hannspad_T71" and confirm with Yes.
    9. Done. Reboot.

    CM 10.1 runs pretty smooth on my tablet, definitely better than stock ROM. Maybe I will try AOKP later, but I am already fairly satisfied.

    Thank you very much Christian Troy, steve30x, CXZa and everybody else who contributed to the creation of custom ROMs for this tablet!

    Hey great news guys. Got a CM 10.2 ROM working like a charm on this thing fast too puts the buggy 4.2.2 stock ROM to shame.
    Does have a few issues but its a great start.
    Follow the steps on this thread except step 1 if you already have fipsy's excellent CWM 6.0.3.3

    All credit goes to the people who made this possible with their hard work like Christian Troy
