This is the tool to create the UPDATE.zip but we need to find the META-INF folder for our HANNSpree HSG1279 device ...

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.

---------- Post added at 04:53 AM ---------- Previous post was at 04:05 AM ----------

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...
[General Questions and Answers] peterc18042:
Lost Root, But

I lost root also after the 4.2.2 upgrade, but I immediately used the Cydia Impactor and about 30 seconds and it was back and Superuser was asking me to grant access to adb shell. I also lost the custom recovery. I will install it in the morning.
[General Questions and Answers] ig6677:
Ok, in Canada the OTA upgrade to 4.2.2 started today as well. Thanks fipsy for the link!
[General Questions and Answers] fipsy:
Now I played around one day with the upgrade. And I must say the only really good thing is that the display-keyboard now works flawlessly. No characters get lost anymore. But aside from some optical and functional changes (configuring user profiles) I cannot detect any advantages over 4.1.1. It's also not any faster than before.

And there are even some disadvantages: Surfsticks like the Huawei E1750 perfectly worked with 4.1.1. Now they don't work at all with 4.2.2. You can get them to work with the App UMTS Manager. But this is no nice solution.
[General Questions and Answers] Sparkrite:
Anybody notice their battery life is abysmal since upgrading?

If I leave the tablet in standby with, say, 75% battery remaining and then 3 or 4 hours later it will

have decreased to approximately 30% or so.

As far as I can see nothing extraordinary running, just the OS and keyboard etc.

Overall I do not think the tablet has in ant way benefited from this "upgrade". :(

In HTCMania have made a backup of 4.1.1 and installed cwm. Notifies you of the ota. I had cwm with 4.1.1 and update to 4.2.2 unable to remove cwm. update me and disappeared. Former factory reset and delete me root. Then I update
[General Questions and Answers] fipsy:
Yes, I did. It's not abysmal but it consumes noticable more energy than with 4.1.1. Especially if you keep Wi-Fi on during sleep. But this already was an issue on 4.1.1. If you keep Wi-Fi on only when plugged in, it consumes just small energy.

On my pad it's not that awful. But as I said, it consumes about 20-30% more energy than with 4.1.1.

I think it's a benefit that the display keyboard now works flawlessly. It drove me crazy that every five seconds two characters got lost when I typed a bit faster.

Today I also had the issue many people reported: I plugged the power adapter into the pad that was turned on. A couple of hours later I came back, unplugged the adapter and tried to turn the pad on by short pressing the power button. Nothing happened. I tried it a lot of times but with no success. Then I pressed the button for 3 seconds. Also no success. Obviously the pad hung. Now I pressed the button for 10 seconds (to reset) but nothing happened.

Then I did the following: I plugged in the power adapter and waited one minute. Then I pressed the power button for 10-15 seconds and to my surprise the battery icon appeared on the display. I waited a few seconds until the display got dark. Then I pressed the power button again for 3 seconds and the pad restarted.

So this error is already there in Android 4.2.2. But as it seems it's quite easy to get rid of it.

I have an app running called "Battery Mix". This records the battery charge state and displays it as a graph. Blue means discharging, red means charging and green means the battery is fully charged and the power adapter is plugged in.

As you can see in the appended diagram normally the red charging graph is not linear because sometimes the pad is working and consumes more power and sometimes it's sleeping. But as you can see, the graph for the last charging procedure is linear. This is because during the charging time not even one single battery value was recorded. When I plugged in the power adapter the pad obviously immediately hung. I suppose this is a system error that still persists.

Tank you! The reason was that this website tries to establish an apparently "secure" connection using the compromised RC4 algorithm which is fully hacked by the NSA and can be read along by nearly all authorities worldwide. So this is just a "fake security". Thats why I deactivated this algorithm in my browser and thus couldn't establish a connection.

It's strongly recommended to every server operator to deactivate this algorithm. Here in germany all operators have done this meanwhile. But New Zealand obviously likes to help the NSA. ;)

---------- Post added at 04:04 AM ---------- Previous post was at 03:39 AM ----------

There is another issue. Meanwhile I heard from three persons that applied the update to Android 4.2.2 (that was uploaded by me) that their G-Sensors don't work anymore as well as both cameras. So we suppose that there are different hardware-versions of this tablet with different updates. We are trying to fix this as soon as possible. Until then I do not recommend this update. It seems to just fully work on devices that have the same hardware as mine. :(

in standby is much improved.

[General Questions and Answers] JimboJoe:
Just to let you know that I got the OTA in France as well. I used OTA Rootkeeper, but I lost root any way. I used fipsy's updated root method which is the quickest one. As SuperSU has a root survival method, maybe we could keep the root if SuperSU was installed before the update...?

Performance feels also a bit worse on my side... I tried applying every tweak of Android Tuner, but that's not much better.

No it was for different CPU in the tablet with Android ver 2.1
[General Questions and Answers] fipsy:
The governors "interactive" and "ondemand" have nearly the same power consumption while interactive works a bit faster. You should never use the governor "performance" because it suppresses any clock-switching for the CPU and holds the device always at maximum clock-rate, performance and power consumption.

Turning off WiFi in standby is the most important thing concerning power savings. WiFi is a really great energy waster on this device.

[General Questions and Answers] fipsy:
As you can see in the Superuser documentation it won't work on Android versions > 4.1.1. If you want to root a system with 4.2.2 or higher you have to use SuperSU. That you are able to gain su access from a terminal emulator or adb shell does not necessarily mean that it will also work with the Superuser app!

---------- Post added at 01:24 AM ---------- Previous post was at 01:12 AM ----------

As I can see from your screenshot you didn't use the App "SuperSu" but the App "Superuser" which are completely different! Superuser doesn't work on 4.2.2 als well as the 3.1.1 binary I recommended in my first posting. But SuperSu works (and also "KINGO Root" as one user told me).

[General Questions and Answers] Kristh:
Hello everyone, and many thanks to fipsy for the rooting hints.

I just want to share may experience about this device.

I've got the stock rom and no root at all, but after a simple reboot the system was dead: black screen with just backlight on :(

The only option was stock recovery and load update.zip fron external sd-card.

I didn't have the original rom, so I tried with each one of the 3 zips (E, U and C).

The tablet works with each one of them (C version has no google market), but none of the sensors are working anymore.

Not only the G-sensor (no auto-rotation at all) but also Cameras, Accelerometer, ... and I didn't yet found an way to revive them.

After rooting, with the CWM recovery, I tried to restore the backup from previous version (you can find the link on this thread), but the device didn't work.
[General Questions and Answers] b0joker:
Where can I find the E, U, & C software you are talking about?
[General Questions and Answers] JimboJoe:
Eight posts above yours ;)
[General Questions and Answers] fipsy:
Sounds like a hardware error. But it would be VERY curious if all of the sensors and the camera wouldn't work anymore at once. The only possible reason would be that they have the same current supply (5V) and the voltage regulator is dead?! The internal voltage is 3,7 V because of the lithium battery. It's not unusual that voltage regulators or power supplies die after being turned off and on again.

Since I updated to 4.2.2 I have another problem thats making me really angry: Not only that it's consuming enormous amounts of battery power even if turned to standby (only lasts for about 1 day in permanent standby) but it also hangs nearly every day at least once. With 4.1.1 I never had this issues. The two graphs that I have appended are showing this: In the evening I turn the display off and in the middle of the night (at about 2-4 o'clock) the CPU stops working and the device hangs without any noticeable reason. From this moment it consumes enormous amounts of energy (about 35% in 5 hours). In the next morning I have to make a reset to start the device. I consider returning to 4.1.1. Android 4.2.2 does not have any benefit compared to 4.1.1. It even has a lot of heavy bugs that turn the device into a permanent annoyance! Also the browser lags much more with 4.2.2.

With Android 4.2.2 I absolutely cannot recommend this device anymore!
[General Questions and Answers] Sparkrite:
Yes Fipsy, I agree wholeheartedly, more or less what I said a few posts back. Unfortunate but true, wonder if they will come out with a fix? :(

Is there any simple way to roll back to 4.1.1 from stock no root/recovery 4.2.2??? This 4.2 update is garbage in my opinion...

[General Questions and Answers] Kristh:
Thanks fipsy for the info. If it would be easy to open I would check the voltage, but there are no screws and seems very hard to disassemble.

About the update to 4.2.2 I also have much more hangs and less battery life: before the faulty reset (and the forced upgrade) it lasted about 2 days, even playing around; the lag was still annoying, but not worse than now.

I'll give a try to the update.zip link posted above and let you know.

If you could install cwm it is also possible to disable the integrity check of the package (if i'm not wrong). Anyway you can follow the suggestion of djport1973 some posts above:

and maybe restore their backup.

If you have problems rooting the device, VROOT works perfectly (with the right usb drivers/android sdk). It leaves some cinese garbage, but then you do a rom restore and it goes away ;)

There is still the alternative to flash the CWM Backup of 4.1.1 with CWM recovery. You will find the links in this thread above (posting #205).

---------- Post added at 10:51 AM ---------- Previous post was at 10:43 AM ----------

I think this is not possible without destroying the body of the device. And you also would have problems finding the right pins and positions to measure.

So I managed to root 4.2 with no issues once I figured out the drivers unless I missed it is there cwm recovery for 4.2 or no? I tried flashing the cwm in the op even though it states 4.1 in the file name but it failed..
[General Questions and Answers] Kristh:
Read carefully the very first post of the whole thread.

"To cut a long story short: Download the CWM-Recovery .... and flash it to your (rooted) device."

You would have a file called cwm-recovery.ima to replace the stock one, no matter the android version you have (that's only a recovery, not the full rom).
[General Questions and Answers] HamBone625:
Thanks a ton didn't see the "continue reading" before that's all it took... I'm gonna blame the device I was reading it on rather then myself haha thanks again!

[General Questions and Answers] Fritz:
Great work guys but like others I find some of this quite confusing (due to my lack of knowledge not your posts).

So I have this tablet on 4.2.2 and if I'm right I can root it by following Fipsy's instructions in the very first post of the thread BUT the final stage should be to install SuperSu instead of Superuser app?

Then I flash CWm Recovery using ADB to make my back ups?

I literally copy the posted code one step at a time once I've got ADB to recognise the device?

[MENTION=5110154]fipsy[/MENTION], settings>Location Access> uncheck Wi-Fi & mobile network access dramatically improves battery usage. I've gone from 24 hours ish on standby to 10% across 8 hours on standby (both with Wi-Fi on.

How did you do that? With an image created by your own using CWM Recovery? Or with a foreign image?

---------- Post added at 10:02 AM ---------- Previous post was at 09:58 AM ----------

It is a vfat image File. Maybe the extension .ima isn't appropriate for Flashify. It's the standard extension for FAT32 images for WinImage. Maybe you have to rename it to .img.

---------- Post added at 10:13 AM ---------- Previous post was at 10:02 AM ----------

On 4.2.2 you may forget my frist instructions that I wrote for 4.1.1. On 4.2.2 the best and easiest way is to flash the (renamed) UPDATE.ZIP for SuperSU using the Recovery: http://download.chainfire.eu/351/SuperSU/UPDATE-SuperSU-v1.65.zip

If you're rooted you don't need ADB. You can flash it with a Terminal Emulator from the Playstore. Or even with Flashify if you don't want to type anything in the shell.

But even 24 hours is quite short. With 4.1.1 it lasted for about 2 days.
[General Questions and Answers] Fritz:
Thanks for the quick reply.

So do you mean literally all I have to do to root this device is follow this step (I was never rooted on 4.1.1; this will be my first ever root on this or any device for that matter)?

"but the App SuperSu is! So download the SuperSU ZIP from here: http://download.chainfire.eu/351/Sup...erSU-v1.65.zip

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

In otherwords copy UPDATE-SuperSu-v1.65.zip to the SD card and use the stock recovery (Vol Up- PWR-HOME not sure of the exact combination atm) to flash it to the device

And apologies I didn't explain the power thing very well. What I meant about the 24 hour thing is that after updating to 4.2.2 a full charge was lasting me about 24 hours. After switching off "Wi-Fi and Mobile Network Access" I use about 10% of battery across 8 hours. So last night when I turned in I had 49% battery and when I woke up this morning I still had 39% left. Wi-Fi & Radio Alarm app on all night, otherwise on standby. I appreciate the drain probably won't be linear but extrapolating a full charge should now last me some 3 days.
