Hi, could you please explain in details how you did to get the 4.1.1?

I'm in the menu of CWM but can't select anything because CWM is asking for a package to install?
[General Questions and Answers] HamBone625:
Hey whats the likyhood that you could build twrp for this beast?
[General Questions and Answers] Sparkrite:
All instructions needed I have posted just before your own post.

Start at post 551 and download V4.1.1. from the link given.

Unrar the file and place the complete "clockworkmod" folder onto your SD card.

Go into CWM and do a factory reset, clear cache and clear dalvik cache.

Then select "restore from SD" (within backup and restore menu)

CWM should automatically see the "clockworkmod" folder (assuming you have directed it to the correct SD card).

Let it do its work and Et Voila!
[General Questions and Answers] john_lenfr:
Yep, I tried but I failed.

Done

Done

Done, Factory reset Ok, clear Cache Ok

It is at this point that things becomes tricky: In my default menu I only have "install package" so it accepts only .img files.

The folder "clockworkmod" is not detected

I have to root my tab? to install something before backup?

"Et voilà" ne fait pas tout le travail malheureusement :)

To summerize,I had a problem with my battery: it was not detected by Android and voltage was at 380mv. I decided to opened my tab (because I don't want to wait for a warranty repair, especially for a tablet that costs nothing) and then I unsoldered wires of + and -.

I recharge the battery with a Lipo charger at 1S 1Amp (waiting to be at 4.2v) and then I resoldered wires.

(I found that the third yellow cable was for protection fuse).

Eventually, I got it repaired by myself.

But I would like to know how to do backups for the future?

I have photos of inside the tab for those who are interested...
[General Questions and Answers] Sparkrite:
Ok this begs the question "Do you actually have CWM recovery installed on the tablet and if so what version?"

The only version that works correctly with this pad is "Fipsys" reworked CWM recovery. A very detailed step by step instruction set, (including links, thanks to Fipsy himself) is given on page one of this thread, have you read that page and actioned it?

You CANNOT do a full backup and restore with the stock recovery.

BTW a handy way of rooting this tablet is with Kingo.............

If I had the time and nerves ... ;)

But I think I do not have them. So the chance is relatively low. Perhaps someone else likes to to that to himself. :eek:
[General Questions and Answers] TrentSterling:
New here. Updated to 4.2.2 before I knew how slow it would be. Came here for downgrade instructions. Used Kingo to root and installed fipsys CWM. Did a backup of my 4.2.2 install. Copying the 4.1 backup right now. (I assume I can have 2 backups in the clockwork folder as long as the timestamp is different)

Wish me luck. This thread has been extremely helpful. I can only pray we get some better performance out of this thing. Maybe a custom rom someday?:confused:

EDIT: 4.1 installed. It's a freakin breeze in comparison. Installed NovaLauncher. Disabled animations. Is there anything else I can do to improve performance?

Can't seem to overclock to 1.2ghz even though I'm on 4.1.1 now.
[General Questions and Answers] john_lenfr:
For those who think that the tablet is slower than with version 4.1.1 you HAVE TO DO A FACTORY RESET to restore fast reaction.

You'll have to reinstall all of your apps but it worth it.

---------- Post added at 09:33 AM ---------- Previous post was at 09:27 AM ----------

Exactly.

So I don't have CWM installed so I can't do backups and recovery...

Ok, but I can't ROOT my tab, and driver I found on first post doesn't work on W7 64b or 32b.

Ok, so this is why the folder clokworkmod was not detected...

Ok, thanks for the link, I will try it sooner as I can...

Cheers,

John

I went back to 4.1.1 too and I'm not able to set the CPU over 1008 MHz.

I tried with SetCPU 2.2.4, CPU Tuner, AnTuTu CPU Master Free and No-Frills CPU Control.

Am I doing something wrong? Or the previous 4.2.2 version left his kernel on my tablet?

Thank you for your help,

[General Questions and Answers] OMIGHTY1:
It's odd that this tablet becomes so much slower with every update. After upgrading to 4.1.1 from the original stock version, it became slower, and now even more so with 4.2.2. It's odd, due to the massive amount of optimizations in that build. Perhaps the software devs at HANNSpree are just terrible?
[General Questions and Answers] zephyro5:
Indeed, I haven't read every posts but I searched the word "1008" which didn't return the post you mentionned. I should look for "1008MHz" to find it.

Thank you for your answer Sparkrite.

[General Questions and Answers] fipsy:
I just read in a german computer newspaper they made a test of the electromagnetic compatibility for this tablet and this test failed. So it's able to interfere with other high frequency equipment. It does not obey the Electromagnetic Compatibility Laws in most countries. So normally this tablet may not be sold in most countries. This may be an important information for all those who want to return their tablet after expiration of the return period.
[General Questions and Answers] wyelkins:
Anyone want to try to build Philz recovery for our tablet? It is based upon CWM but with many features added, included an option to root.

I have been using it on my S3 since the start of AOSP 4.4.2 Roms and it is still the best in my opinion. There is a large active community for this recovery and Phil himself is a knowledge resource. There is a long list of supported devices.

Will probably not be easy because Ainol Devices are not supported. So a lot of modifications would be necessary.
[General Questions and Answers] zephyro5:
Don't worry, it's okay ;)

And now, after only 3 days having boosted the CPU to 1200MHz I can confirm that it's not a good idea...

I can't boot into 4.1.1 and no camera and sensor into 4.2.2... So, it seems I'm good to open my device thanks to the help of Fipsy ;)
[General Questions and Answers] fipsy:
Could you revive your tablet by re-soldering the battery cable?
[General Questions and Answers] zephyro5:
Yes, with your help (http://xdaforums.com/showpost.php?p=51568288&postcount=451), it was pretty easy.

But I kept the device opened during one week to troubleshoot it. At 1200MHz and without the metal back cover, it hung after some hours... But I only need to press the power button for 8 seconds and restart.

So the device really need a heatsink to run correctly. Maybe with a good dissipation, the device could run perfectly at 1200MHz...

For now, I set it back to 1008MHz because I don't want to open it everyday!

And I also soldered a longer cable to prevent multiple desoldering/soldering on the printed circuit board.
[General Questions and Answers] fipsy:
What about sticking a reed switch to the back? Then you can disconnect the battery just by holding a magnet near the position where the reed switch is inside.
[General Questions and Answers] Sparkrite:
Doesn't a reed switch normally work the other way ie. closed when magnet is in proximity and open when moved away?

Also the metal back isn't going to be conducive to reliable magnetic operation.

Nice idea though, but might need a little work.......;)
[General Questions and Answers] fipsy:
Thanks for the hints! But just rooting will not speed up your device! Wich "weird" apps did you uninstall that gave you more perfomance?

I took gmail, maps, YouTube, and Google search and installed then from the market. I also removed all the wallpapers and music fx...whatever that is, its constantly running..and the video editor since I really don't plan to use the useless cameras on here anyways. I also turned off all the logging, as well as most animations and it runs a lot better. If only I could get the optimum cable TV app to work, as well as the NHL gamecenter to play live games.

Don't buy this piece of junk. Mine died 10 days after I got it from Walmart. Nothing happens when I press the power button for 15-30 secs with the charger connected. Occasionally the screen lit up but nothing on display. Called support and they suggested holding down power + volume + and - key for 15-30secs and that didn't do anything either. They suggested RMA.

Please help.

So, I have been reading the above listed operations on how to root the Hanspree HSG1279 which I now own. Quite honestly I am a bit confused on where to start. If someone could help me with a step by step solution on how to root this device from the time I plug it in to my PC that would be very helpful. I have never attempted to root any device before so I am trying to insure that I do this correctly the 1st time. Please know, any and all help is greatly appreciated.

[General Questions and Answers] fipsy:
Are you able to boot into the Recovery? Hold down "Volume -" and then press the power button for 3 seconds. Release the power button and keep on holding down the "Vol -" until the Recovery menu appears (takes about 20 seconds). If this isn't working your device is subject to RMA.

I appreciate that it worked for you. I will concede to the fact that you are much smarter than me in regards to this. So please offer assistance.

When it says After starting ADB Shell you can gain root permission on the device by typing SU. Where is that telling me to type su at?

Am I missing a step? Please help, Thanks Shanco85
[General Questions and Answers] fipsy:
Okay, thats more precise. So you didn't have problems installing the USB drivers but just finding ADB. :)

You need to download the Android SDK (https://developer.android.com/sdk/index.html). Unpack it (e.g. to a folder called C:\android-sdk) and you will find a folder called "C:\android-sdk\sdk\platform-tools". Within this folder there is a program called "adb.exe". Start a Command Shell by clicking on the Start button and entering "cmd" in the search box. Within the Shell navigate to the folder mentioned above by typing:

C:
CD \android-sdk\sdk\platform-tools

Now you can start adb and list the connected devices:

adb devices

If your USB drivers have been installed successfully and the tablet is connected you should see your tablet as a quite long combination of numbers and letters representing your device. Now type:

adb shell
$ _

and you should see the command prompt ($) of your tablet. Now you're ready to type any shell commands to your tablet.

Cheers, Volker

MTK Droid Tools also need ADB. So first check if your device is recognized by adb using "adb devices" command.

I'm not sure if MTK is able to root this device. I cannot recommend using it! It may brick your device. There are no experiences using it. So if you just want to root your device I'd prefer to do it manually.
[General Questions and Answers] ou2mame:
An easier way to do this is to shift right click the folder that adb is in and then click command line to start.. Then just type adb shell and then go from my here

[General Questions and Answers] fipsy:
No, there are closers as well as openers and even changeover switches. This one could be suitable.

As the metal back is made from thin aluminium it is just slightly paramagnetic and thus doesn't affect magnetic fields. So there should be no problems operating the reed switch with a small neodymium magnet.
[General Questions and Answers] Sparkrite:
You're absolutely right Fipsy, I didn't bother researching what is available now. (Tut! Tut! Sparkrite, quick slap on hand)

One concern would be its CCC (current carrying capacity) as I think a reed that could handle close to 1A may be required.

But, all in all, a very possible solution, to not having to open the pad each time to hard reset.

Infuriating that it can't handle 1.2Khz , its "supposed" rated speed.
[General Questions and Answers] fipsy:
The operating current of this switch is 1.5 A. Just the switching current is 0.25 A. If the tablet is crashed you should boot into CWM recovery before disconnecting the power. In recovery mode the current consumption should be less than 0.25 A. I didn't prove that but I'm quite sure.

Another issue would be that a switch with 1 A switching current has more than 3 mm in diameter and thus couldn't be placed between mainboard and back cover. So it could be a good idea to use two small switches as a parallel circuit. If you place them rotated by 90 degrees to each other you will have another benefit: Good shock protection. If the tablet gets a stroke only one of the switches may accidentally open. The other one always stays closed.

Perhaps you should place an additional small self adhesive thermal pad between the back cover and the most strongly warmed up components.
[General Questions and Answers] Sparkrite:
Well, you have certainly thought about this. :)

Your quite right, two in parallel would work alright and as you say have the added bonus of being very unlikely that both would open at the same time due to shock.

I have never had any problem with my tablet (touch wood), but I am running it at 1008Khz and V4.2.2 and it very seldom lags, does all I want it to do, ie. reading,browsing,youtube and Netflix.

I suspect the battery is starting to get a little tired as its not holding as well as it used to, not very good as its only six months old.
[General Questions and Answers] fipsy:
It's no problem to replace the battery by yourself. I'd recommend to use two flat lithium cells with 4500 mAh. You can buy them nearly everywhere for about $10-20.
[General Questions and Answers] Sparkrite:
Fipsy will you do me a favour please?

Next time you have your pad open will you measure the battery and give me the dimensions.

I wonder are you better off with two batteries as it means more cells have to stay balanced for optimum output/longevity.

I have changed batteries in other pads but, believe it or not, I haven't opened this one yet.

Thanks in advance.
[General Questions and Answers] fipsy:
Since the last repairing I didn't have problems. But it's just a few weeks ago and I didn't use the tablet much often since that time. But if I'll open it again I'll determine the dimensions of the battery.

As far as I know there are no single cells with 6000 mAh or more capacity that are slim enough to fit into the tablet. So two cells are connected in parallel. I think most slim batteries for tablets will fit because they all have approximately the same height. If you connect the batteries in parallel you do not need a balancer because different voltages of the cells are automatically compensated by different (dis)charging currents. Only if you connect batteries in series you will need a balancer to prevent deeply discharging or overcharging of particular cells. It's just that it may be necessary to buy cells with an integrated protection circuit because I don't know if the tablet has a protection circuit.
[General Questions and Answers] zephyro5:
The best way, would be a Normally Closed Reed switch (form B) but it seems to be difficult to find them...

I think maybe a bigger diameter should fit in between the PCB and the battery.

If I had to open my pad first (I hope not), I'll give you...

[General Questions and Answers] franzmueller:
This is wierd. I have kind of the same problem.

Yesterday the battery of the tablet drained very fast. Without me doing anything the battery was empty after a few hours. I tried turning it on again and it showed the empty battery icon. So I plugged the wall charger and tried to recharge it over night. This morning the tablet doesn't want to do anything. I already checked the wall charger and it seems fine to me. Trying to load with USB+wall charger now hoping to get the thing running again.
[General Questions and Answers] zephyro5:
The last time I had to play with USB and wall charger it took me some time before the pad want to boot (plug in, plug out, plug in...)

And I realized that the battery was drained, like there was no protection to prevent it to completely go empty.
[General Questions and Answers] franzmueller:
I decided to open the tablet to measure the voltage of the cells.

Between the red (+) and black (-) cable I have 4.1V, between the red and yellow 2.29V and between the black and the yellow 1.67V.

I'm not an expert with electricity, but this is what it looks like for me:

One cell is really f**king empty and therefore pretty much dead and the other cell is quite low, but won't recharge because the tablet refuses to load when one cell is dead.

I'd like to hear some other opinions on this!!
[General Questions and Answers] fipsy:
Don't think so. The cells are connected in parallel so a Voltage of 4.1 Volts indicates the cells are fully charged (maximum 4.2 V). The yellow cable has another purpose.
[General Questions and Answers] franzmueller:
Okay, my bad. I thought they were in circuit.

I still hads no luck so far. I tried every button combination I could imagine, plugged and unplugged wall charger and USB several times. I definatley have no backlight like some people described in earlier posts. :(
[General Questions and Answers] fipsy:
I also had this problem in the past. But since the last repair it's gone (knock on wood). But I always could revive the tablet by plugging the power adapter for about 12 hours. Are you able to boot into recovery?
[General Questions and Answers] franzmueller:
No, I can't do anything, screen stays off the whole time.
[General Questions and Answers] franzmueller:
Good news. After hours of recharging with both USB and wall charger I finally was able to boot again.

I kept measuring the voltage and it didn't change so I can't say for sure that this was the problem.
[General Questions and Answers] fipsy:
The voltage of the batteries surely wasn't the problem. There are a lot of problems with this tablet that cause this and other strange behaviours (like non-working camera and g-sensor).

Hi guys,

I think the general slowdown over time on this tablet is due to the lack of TRIM support in Android 4.2.2.

This is a very interesting information! Thank you! So Android 4.1.1 is capable of TRIM?

Another information that may be interesting for some people: As some users will know I sent my tablet to the repair service twice because of a non working g-sensor and camera. First time the reparation only lasted for about 6 weeks. In the meantime the second repairing is about 8 weeks ago and the tablet still works flawlessly. This feeds the hope that the second service has been successful and that it really seems to be possible to fix this issue without changing the mainboard.
