[General Questions and Answers] fipsy:
Where do you have this information from? Or did you open the tablet? And if so: How?

---------- Post added at 02:43 PM ---------- Previous post was at 02:37 PM ----------

I cannot confirm this. When I had my tablet boosted to 1200 MHz (I don't like to say "overclocked" because it's just that what the manufacturer promised) it was on the highest clock speed for about 60% of the working time. And I do not play any games! Even when fetching mails with k-9 or browsing on the internet it immediately went to 1200 MHz.

---------- Post added at 02:58 PM ---------- Previous post was at 02:43 PM ----------

As far as I know up to now there is no way to root the device directly if using the latest OTA update from February 18th.

First you have to apply the OTA-update from December 19th, 2013: Copy it to your SD-card and apply it via stock recovery. (E = European Version, U = US Version)

Then you have to reboot the device into android and activate USB-debugging in the developer options.

Then connect to your device using adb shell. You immediately have root access and may push the CWM recovery to /dev/block/acta.

Then start into CWM recovery and apply the SuperSU.zip. And then you may apply the OTA-update from 18th of February again.

Tyvm fipsy for a quick response with pertinent information!!!!! I'm out most of the day today but as soon as I get home I will try that! But I never would have figured that out on my own, thank you so much. I will post a response to let you know how it goes right after I get a chance to tinker some more with it.

for example see here .. https://www.youtube.com/watch?v=dtvuvPEseKg&list=PLSueOvyhPUe-w2YwwwZmCEgcYP4tDFPya

No the term-pads or heat-sink on the CPU!!!
[General Questions and Answers] fipsy:
Depends on how hot the CPU is getting. But it's a bit strange that the g-sensor and camera are broken if the CPU is getting too hot. I don't think it's possible to upgrade the CPU with an effective heat-sink because there is too less space and no possibility to connect the heat sink to the metallic rear panel which would be most effective.
[General Questions and Answers] ig6677:
Why .. is not possible to put the thick thermal-pad between the CPU and the back-cover? Or between the LCD panel and the CPU?
[General Questions and Answers] mrosebro:
Thank you fipsy!

UPDATE: THIS WORKED! fipsy i could KISS YOU! thank you thank you thank you! *does little dance*
[General Questions and Answers] fipsy:
Hmmm. I couldn't exactly see in the video where the CPU is. Is it on the front side of the mainboard (where the display is) or is it on the back? If it's on the back your suggestion makes sense. But discharging the heat to the display definitely is no good idea. Not only because the display is a quite bad heat sink.

---------- Post added at 12:31 AM ---------- Previous post was at 12:28 AM ----------

:highfive: I'm glad to see you lucky. ;)
[General Questions and Answers] fipsy:
I don't think the display has an aluminium back. I believe the only way to keep the CPU cooler could be to attach a thin but large (black) aluminium plate with a double-sided self-adhesive heat conducting film to the three components visible on the front side (CPU and NVRAM?).
[General Questions and Answers] ig6677:
Yes... it may works ..
[General Questions and Answers] fipsy:
Perhaps this heat sink kit could be a solution. It was made for the Raspberry Pi and is only 5 mm high. Maybe this could fit into the tablet: http://www.reichelt.de/Heat-Sinks-I...&ARTICLE=133189&SHOW=1&OFFSET=500&LANGUAGE=EN
[General Questions and Answers] ig6677:
Nop... too high ... it's almost no space between the panel and the CPU..
[General Questions and Answers] Bluze:
THIS one looks to be 2mm. Kind of pricey though.
[General Questions and Answers] fipsy:
If you disregard the shipping costs which are $8 to europe. It's not that much but a delivery time of 15-30 days is also not very fast. ;)
[General Questions and Answers] Bluze:
Oh, it's only $1.50. Something lower down caught my eye that was 17.99, thought that was the price for the heatsink. But 8 shipping and 15-30 days delivery time isn't good.
[General Questions and Answers] fipsy:
And there is no guarantee that putting a heat sink onto the CPU really solves the problems when boosting to 1200 MHz!
[General Questions and Answers] fipsy:
I have the same error again as 11 days ago: After trying to reboot the device only the HANNspree logo appears and the device doesn't boot anymore. This is the same error why I let it repair 14 days ago. Now I'm REALLY annoyed! And I want to get rid of this device. It's simply rubbish!

Seems this error frequently appears if trying to reboot the device. And it has nothing to do with overheating.
[General Questions and Answers] fipsy:
I didn't have the nerve to send the tablet to the repair service again. I was so annoyed that I tried to open the device to see if I could do anything by myself.

It was very easy to open the device. Just stick your thumbnail into the small notch between the display and the back of the device and cruise around the whole device with your fingernail. You will hear the pins snapping out of their clamps. Now you can easily open the device.

I'm attaching two pictures of the inner life of the tablet. You will find this pictures in full resolution here: http://yadi.sk/d/clP7I8jFLdh3d and http://yadi.sk/d/TBlwicSKLdh4S. On the first picture you can see the aluminium back on the left and the display with the mainboard and the battery attached on the right. As you can see there ARE heatsinks on the CPU and NVRAM! It's the white squares. And they touch the aluminium back if the device is closed. So there should be NO heat problem at all!

On the second picture you can see the mainboard. On the upper left there are the soldered battery connection wires (black an red). When I looked closely at the whole mainboard and especially at the battery connection wires I noticed that the soldering point of the red wire wasn't glossy but matt and had dried flux residues around. So it must have been disconnected by the repair service. Because there was no other position on the mainboard that looked the same I supposed that only the battery had been disconnected by desolerding the wire.

So I did the same. After desoldering the wire and connecting it again the backlight was off. I pushed the power button and as you probably supposed the device was faultlessly booting and running. So this is the complete "repairing" process. :silly: :p

As many people reported the device could not be shut off. The backlight always was faintly illuminated and the battery animation didn't appear. Even the shell command "reboot -p" is not able to shut it down in this condition. Also the camera and g-sensor often don't work anymore. It's all just because the device got somehow hung. And it can only be reanimated by turning the power completely off. And this simply is not possible! Except if opening the device and temporarily disconnecting the battery.
[General Questions and Answers] Ajsh:
Wow this is great news. I will immediately root it and push up the CPU clock! Great fipsy, and as always it's greatly appreciated that you share your experiences!

Even I can do this simple service:P maybe it's worth connecting a a small powerswitch between the battery and board for future problems? :P maybe it's not the best solution to open it every time, but with the switch the soldering isn't needed
[General Questions and Answers] fipsy:
You only have to be very careful not to accidentally short circuit the battery with the soldering iron when desoldering the battery cable! I recommend to cover the other soldering points around with kapton tape.

I thought the same. Perhaps there is a more convenient solution with some additional hardware... Maybe with a reed switch that can be activated by a magnet from outside the case.
[General Questions and Answers] Bluze:
Been too long since I sent mine back, there isn't a reset switch? I guess you could cut a small hole where the battery wires are and put a momentary switch in to make one. That really seems like a bad mistake that they didn't allow for that in the design.

Just noticed what you said about a reed switch. Better idea than cutting.
[General Questions and Answers] fipsy:
No there isn't. You may just reset it by pressing the power-switch for more than 8 seconds. But this isn't a hard reset - the power isn't disconnected just a reset pulse is sent to some components. Seems that at least the g-sensor and the camera aren't always able to react to this pulse. Maybe some other components neither.
[General Questions and Answers] ig6677:
Thanks fipsy for the pictures... but where is no thermal-pads on the flash chips! The thermal pad is located on the CPU and the charge controller IC.
[General Questions and Answers] fipsy:
You're right, the H5TQ4G63MFR are the DRAM and the H27UCG8T2ATR are the NAND Flash. They don't have thermal pads. But wherefrom do you know that the second chip with a thermal pad is the charge controller? :o
[General Questions and Answers] JimboJoe:
What about simply letting the device emptying the battery by itself?
[General Questions and Answers] Bluze:
This is just a guess, but I'm thinking there is most likely a protection circuit to prevent total battery drain. I know you really don't want to do that with multiple-cell batteries.
[General Questions and Answers] neonum6:
guys I noticed that, when attached to the charger, performance seems to be better... did you had the same impression?

Maybe part of the performance problem of this tablet can be solved tweaking the power save policy..
[General Questions and Answers] fipsy:
Especially because a Lithium Ion Battery is dead and cannot be revived after having been deeply discharged to less than 2.8 volts.

There are lithium batteries with and without protection circuits in the market. If your battery has no protection circuit you have to ensure yourself that it will not be deeply discharged or overcharged. Lithium batteries - different from other batteries - have no maximum voltage. The safe maximum voltage is 4.2 volts. But you may charge them up to about 12 volts before they explode (http://www.youtube.com/watch?v=NRDyw70AbPs and http://www.youtube.com/watch?v=p21iZVFHEZk). You also must not discharge it to less than the manufacturer recommends (2.8 to 3.2 volts) or it will be destroyed fairly quickly.
[General Questions and Answers] fipsy:
Yesterday my device had the same error again. It's the third time within one month. I noticed it by a non working g-sensor and camera. After normally shutting down the device it didn't start again. Just a black screen and if I pull in the power adapter a pale backlight. I opened it, disconnected the battery and soldered it again. After this procedure the device was working normally.

One thing is very interesting: The first time this error occurred on 21st of march, then on 1st of April and now on 12th of April. Do you notice something? It always happens in a period of 11 days! Very strange! I suppose this really is a defect. Especially because other users who are also running Android 4.1.1 didn't ever have any problems.

I will wait for the error to occur one more time. And if it happens next time I will send it to the repair service again. Expecting to get a new device that is hopefully working.
[General Questions and Answers] Bluze:
Thanks for posting that. I've been considering buying another one on the chance that I just got a bad one, but you're having very similar problems.
[General Questions and Answers] haircut313:
Do anybody notice the faded dull color when switching from 4.2 to 4.1
[General Questions and Answers] fipsy:
We are not the only users having this problems. At least I know of 5 other users. But there are also users who never reported any problems. So maybe it's a hardware issue as well as it maybe a software or handling problem.

---------- Post added at 11:12 PM ---------- Previous post was at 11:10 PM ----------

What did you do for switching back?
[General Questions and Answers] Sparkrite:
I have been running 4.2 with all the OTA updates (2 I think) since it became available and , touch wood, have had no such problems.

The tablet is rooted and has Fipsys version of CWMs recovery installed.

In fact the tablet is running quite well and hopefully it will stay that way. :)

Unfortunately maybe Fipsy, and others, got a faulty batch or something similar.
[General Questions and Answers] fipsy:
Android 4.2 even boots if the g-sensor and camera are not working whereas Android 4.1 becomes stuck in the HANNspree-Logo. Maybe Android 4.2.2 or the shutdown procedure of 4.2.2 prevent the g-sensor and camera from getting stuck.

Perhaps I should make a test with Android 4.2.2 to see if my tablet also works faultlessly with this android version. But I don't like 4.2.2 because of it's screeen layout with fewer space for icons and especially the missing support for UMTS surfsticks that I sometimes use.
[General Questions and Answers] Sparkrite:
Yes, trying 4.2.2 for a while would be interesting re: the g-sensor and camera.

You would get over the icon spacing but I can see how not having support for a modem could be a piss-off.
[General Questions and Answers] fipsy:
Maybe I'll try this for some weeks. To resolve the modem issue you could use a surfstick with a built in WLAN access point. But I don't like to buy a new surfstick just because of this botched android version.

By the way: Google intentionally removed the surfstick support to push their tablets with integrated 3G modems. It's no mistake but user-unfriendly marketing. The same happened just a little later to the USB memory-stick-support that was intentionally removed together with the external sd-card-slot in the nexus tablets to prevent the user from easily extending the internal memory. Google has somehow as well become a "piss-off" in the last year(s). ;)
[General Questions and Answers] wankelrx8:
I bought this tablet back in December, 2013, and it had some lags. I accepted all the OTAs up until now, and am on 4.2.2. The tablet was practically unusable, with extreme lags and freezes. I read a post from Fipsy about doing a Data Reset, and it really worked well! I installed the new Chrome Beta, and even that runs normally, whereas Chrome was completely unusable before. Thanks for the suggestion and keep up the good work, guys. Is it really worth rooting for overclocking purposes? From what I've read, you have to be on 4.1? Sounds like there are some issues with this...
[General Questions and Answers] fipsy:
I hope it remains that way! I had the problem that after about 14 days the tablet began to lag again with android 4.2.2. That's why I reverted to android 4.1.1. But that version seems to have an evil issue with the g-sensor and camera. So as I see it at the moment there is no android version for this tablet that is without heavy bugs.

Overclocking only works with android 4.1.1. With 4.2.2 you are not able to get the full performance of 1200 MHz from the tablet as the manufacturer promises. 1008 MHz is the maximum. Clocking to 1200 MHz gives about 20% improvement in performance.
[General Questions and Answers] wankelrx8:
Well, I'm having the camera and Gsensor issues on 4.2.2, so I guess it's not just 4.1.1. I'm going to stick with 4.2.2 for a while, unless I really feel that I need to get the camera and g-sensor working.
[General Questions and Answers] fipsy:
That's an interesting information! But if the g-sensor isn't working you're not able to switch the display automatically from landscape to portrait and vice versa. Don't you mind?

You can solve this issue (at least for 11 days) by opening the tablet and disconnecting the battery for some seconds. But you need a soldering iron for that.

Good one Fipsy !! :laugh::laugh::laugh::laugh::laugh::good::good:
[General Questions and Answers] fipsy:
This tablet somehow makes me sarcastic. :silly:
[General Questions and Answers] wankelrx8:
I guess the auto rotate feature is not such a big deal to me. I use it in landscape mode mostly, like a PC. I think it really sucks that the camera doesn't work, 'Can't connect to the Camera' error. But, that doesn't bother me much either because my phone takes better pictures anyway, and is WAY more convenient to carry around. For now the tablet is doing what I want it to do, Gmail, Facebook, plays video, Web browsing. I can live with those things, as long as it doesn't slow down again. I may have to do another data reset if it does. :(

How can I stop constant OTA notifications system update available?

Hi All.

I am a newbie and this might be trivial to resolve. (I hope!)

After rooting, how do you prevent receiving OTA notices a system upgrade is available?

I am at 4.1.1 and receive notices about every 5 minutes a new system update to 4.2.2 is available. It is very annoying!

As I said I'm a newbie and have tried reading through the 40+ pages here and don't see anyone with this problem --

sorry if this is a silly request but having to constantly dismiss theses notifications is quite frustrating.

Any help would be greatly appreciated! THANKS!

[General Questions and Answers] franzmueller:
Try to disable the update APP in the settings. Works fine for me.
[General Questions and Answers] leocarroll:
Nothing there

Thanks for the response franzmueller!

If you are talking about the Software Update under About Tablet, I have nothing available there. When I touch that panel and am connected to the internet, it immediately provides the OTA available notice. If I am not connected, it says Network Unavailable and says it needs a network connection and offers to go to network settings or close. Those arre the only options.

Apparently on other versions of the system there IS a setting to shut off the OTA available popups. But not on my system.

I am at 4.1.1, Kernal 3.4.0 Aug29 and Build 20130829U-V1.1.0_HJT-FW8963-10.1-0x27-0x05.

I had previously called Hannspree Tech and they suggested the same as you, but when I told them I had nothing to shut off they said it must be I had a different version. On previous versions I guess you could shut off the OTA. But not on 4.1.1

In searching these forums it also seems that each phone or tablet has a specific procedure to shut off these OTA notices. I haven't seen any procedures specific to this tablet.... and I haven't seen anyone else complaining about this nag.

THANKS for trying!

New CWM Recovery v.6.0.3.3.a

Hi all!

I worked on a new CWM-Recovery and finally completed it. With old recovery v.6.0.3.3 you have not been able to mount the internal and external SD-Cards as USB mass storage devices on your (Windows-)PC.

This may be very important if you are not able to access the internal sdcard via adb shell because the USB-drivers are not working or because of other issues. If you want to copy for example an update-file to sdcard for flashing with cwm-recovery this would not be possible if you cannot push it via adb. You would have to boot into android to do this. But if android isn't booting you have a problem. :silly:

If you select in CWM-Recovery

- mounts and storage

- mount USB storage

nothing happens and the logfile in

- advanced

- show log

shows:

W:Could not enable /dev/block/actj on LUN 2

This is because on this tablet the LUN directories are non-standard. I modified CWM to work with the HSG1279. If you choose the above command on new CWM-Recovery v.6.0.3.3.a you will notice on your connected PC an additional drive being added. If you have an sdcard in the external sdcard-slot of the tablet two drives are being added to your PC.

This is the only (but quite important) change in CWM-Recovery v.6.0.3.3.a. Everything else is unchanged.

Today my device had the known error for the fourth time: A non working g-sensor and camera. This time I will not open it again and disconnect the battery but send it back to the repair service hoping to get a new one.

The first time this error occurred on 21st of march, then on 1st of April, then on 12th of April and now on 5th of May.
