[Resolved] HANNSpree HSG1279 root and recovery!!! [Updated 01/28/14]

[Omegadrive]

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:

$ su
# cd /system/xbin

Mount the system partition read/write:

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

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

# mv su su-orig

Copy the binary to the xbin folder:

# busybox cp /sdcard/su ./su

Change the permissions:

# chmod 6755 su

Mount the system partition read-only and exit:

# 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:

/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

  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

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!

Hello.
Long time has passed. Does anyone have the mentioned file CM10.1_Hannspad_T71.zip (see http://forum.xda-developers.com/showpost.php?p=58325450&postcount=854)?
Thanks.

Here you go.

294.92 MB file on MEGA

mega.nz

It was very helpful when I needed this file. At the time I did some serious search before locating it.

I had it still on an SD card just in case someone was in a similar situation.

So many thanks! Indeed, I downloaded and found out my tablet is the S74 and not the S71.
However, all the custo ROMs developed I have found are for the S71. On S74 I have only found the root jailbreak.
Does anyone know if there is a customized ROM for S74?
Thanks!
