Newer Chipsets and ADB incompatible

For some reason the newest Intel chipsets (don't know about AMD) are allergic to ADB and Fastboot. It seems to be true regardless of operating system, 32 or 64-bit, whatever. I keep a P4 system around just to play with Androids, as the last 2 PCs I built want nothing to do with them, even under 32-bit Linux OSs. It seems to have nothing to do with the well-reported problems with USB3 and adb, I always make sure I use a USB2 port.

I would like to find out how to get Linux to see the Hannspad, it's the only one I need to use Windows for. So far, anyway.

Binary Link not working

Hi, guys. First of all, thanks for all the work you've done. I have a problem with my rooting process, because i can't get the suggested binary. (3.1.1). I'm running android 4.1.1. Would you please fix the download link? Thanks in advance. Best regards.

Anyone had a success using kingoroot in Windows 8.1?

If so how did you manage it?

When I try it freezes the tablet during the root process.

I have tried using a virtual machine with xp and windows 7, same problem.

Have also tried on a laptop running Windows vista.
[General Questions and Answers] steve30x:
Sorry for the off topic here but I am curious if there is any Custom roms for this tablet. I was thinking of buying it but looking at the problems with android 4.2.2 I might stear away from it. It would be nice to get android 4.4.4 or android 5 on this tablet.
[General Questions and Answers] kevinthefixer:
I would beg, borrow, steal or buy an older machine, XP or 7. Install the Ainol dirvers first. Or simply buy Windows 7 and get rid of 8.1; That's what I intend to do with my only Win8x box.

[MENTION=4218632]steve30x[/MENTION]: please let us know if you do find a custom ROM for it. In the meanwhile, mine runs very well on stock rooted 411, and if you shop around a bit you can find one cheap. This is a whale of a tablet for US$100. Throw in fipsy's CWM recovery to ice that cake and it's hard to beat.
[General Questions and Answers] Sparkrite:
No custom roms so far.

I now have the T74 and it really is a different machine altogether, it is what the T71 should have been.

But unfortunately no root or CWM backup so far.

C'mon Fipsy buy one and get working on a recovery and root.

Did you try vroot? It has some security issues but it worked on my huge SN14T71.
[General Questions and Answers] fipsy:
Before I would do that I'd try to use other mechanisms than Kingo to root the device. Normally it's done within a few minutes! And there are a lot of explanations here in this thread just a few postings ago.

I didn't test kingo with Windows 8.1 but I don't believe that this OS is the problem. I'm only working with Windows 8.1 and everything I've done with this tablet until now I've done with Windows 8.

[General Questions and Answers] shanco85:
After I start the cmd prompt when I type in adb devices, I get no results. Which is a bit confusing because the tablet is connected to the pc. I confirm this by going into computer and seeing Hannspad as the F external drive. I can open the drive and have full access to all content. So what am I missing?

Thanks for all of the help.

If you are installing the USB drivers in Windows 8 you have to follow exactly the steps Omegadrive described here: http://xdaforums.com/showpost.php?p=48307550&postcount=10

If the USB drivers are installed and the device is shown in the device manager as "Android Device" -> "Ainol Composite ADB Interface" and it still doesn't work you may probably have forgotten to activate USB debugging in the android settings (developer options) on your tablet?!
[General Questions and Answers] shanco85:
So followed Omegsdrives process for installing the drivers and now see the device attached as "Ainol Composite ADB Interface" in device manager. I also have confirmed that usb debugging if enabled within the tablet. I am still not seeing the tablet after using cmd and inputing adb devices??

My tablet has a section beneath usb debugging that says "select debug app" could this have anything to do with it?

You have to add the ini thing I posted and restart PC, then you will see it ;)

I created the ini in the text doc. Was I supposed to move that to a new folder or leave in the .android folder? I have followed everything I can find and the CMD is still not finding any adb devices. I am certain the device is enabled for debugging and as the pics above show the device manager is showing it as an adb interface. Any other suggestions?

Thanks, Shanco85
[General Questions and Answers] Symbiotic12:
I followed this and when I install from the device manager it comes up with "Windows has determined the driver software for your device is up to date." The steps I take are Device Manager -> Portable devices -> Hannspad -> update driver software -> browse my computer and install from the folder.
[General Questions and Answers] Omegadrive:
The file stays in the .android folder, make sure you can see extensions in Windows so it doesn't end up as .ini.txt

Also, make sure the device is set as MTP device, don't enable USB storage or it will not work.

That's all I can think of atm.

On another note,

I sold the tablet to my brother, he couldn't buy one on time and he wanted as a x-mas present for his son, so yeah, I can't test anything anymore, oh well, good luck to you all, at least I helped others get somewhere. :)

i get the message -rwxrwxr-x root root 380532 2013-12-20 17:47 su - what does this mean please?
[General Questions and Answers] fipsy:
The problem is that not only the processor has to be the same but also the complete filesystem. I flashed the CWM Recovery for the "Ainol Novo 10 Hero" - from which the HSG1279 is nearly a clone - about one week ago and it didn't work. I could boot into the recovery but nearly nothing worked because the mounts are completely different. I don't think that any foreign recovery will really work. We have to build our own special recovery for this device. It's not that difficult but if you haven't done it before it's quite complicated.

Another issue: I have an enormous accu drain on my device. If the display is off and I just let it lay around the accu is empty within 19 hours. With a capacity of 6000 mAh this means there is a permanent current flow of about 315 mA. This is really unbelievable and makes the device nearly unusable...

---------- Post added at 12:41 PM ---------- Previous post was at 12:18 PM ----------

This means that the new superuser binary is present on your device but has the wrong permissions.

The original su should look like that:

-rwsr-sr-x root root 62932 2013-07-28 10:14 su

Obviously you have already copied the new su binary on 20th of december at 5:47 pm but you have forgotten to set the right permissions after copying the binary.

Did you rename the original su before copying as I recommended in my first posting?

If you followed my instructions you should have the original binary backed up with the name "su-orig" from which you may still gain superuser access by typing su-orig. After doing this you may continue with the "chmod"-step. If you didn't rename the original file to su-orig you now have a quite big problem...
[General Questions and Answers] erdoboy:
I did save the su-orig which i type in and do then get the # sign however when i do the chmod step it says "unable to chmod su: read only file system. Is there anything I can do please?

Thanks for all your help on this
[General Questions and Answers] fipsy:
Okay, then enter the following:

$ su-orig
# mount -o remount,rw -t rfs /dev/block/st19 /system
# cd /system/xbin
# chmod 6755 su
# mount -o remount,ro -t rfs /dev/block/st19 /system
# exit
$ exit

I think everything will be fine after that...
[General Questions and Answers] steve30x:
If I find anything I will let you know. I think I'll chance my arm with this though. At the moment I have an Acer A500 with Thors Omnirom (Android 4.4.4) and though it runs ok its a very slow tablet. I also have the Galaxy Tab 4 7" but the screen is too small for my poor eyesight. I thought that this being a quad core tablet it would be ok. I am guessing the lack of ram is the problem with this tablet though. Have you guys tried uninstalling any unnecesary apps in the tablet. I've noticed that in all tablets I've owned in the Android OS some phone apps are left in there and running in the background like the dialer and messaging along with a few other phone apps that are useless on a tablet and once removing them frees up some ram and slightly increases the performance and you gain slightly more battery life. Also another problem for the sluggishness could be the drivers arent written properly.

The tablet is for sale here in my town for €129 with free headphones and a free antivirus (which I wont use). Also on the box the manufacture date is May 2014. Could it be improved any bit? If I do decide to buy the tablet tomorrow I will try to root it and see if theres any apps left behind that are of no use. By thew way whats the highest stable CPU speed managable with this tablet? I see the T74 is at 1.3GHz with the same CPU. Maybe somebody might be able to port the android OS from the T74 over to this tablet. Looking at the specs they are almost identical hardware.

Managed to get it rooted with Iroot, had to disable most of my computers security to do it. But for some unknown reason, lost root approx 12 hours later, no idea why.
[General Questions and Answers] steve30x:
I got the tablet this morning and I can see why people say its slow. The tablet came with 4.2.2 already installed and its slower than my much older Acer A500 dual core tablet. I'm going try and root the tablet and see what I can do with it though.

** EDIT **

I got the tablet rooted and CWM installed (The newest versio) but now I have a big problem. When I reboot the tablet it shows the hannspree logo for a few seconds then boots straight into CWM. I've tried flashing a new rom and wiping the tablet then install a new rom but it dosn't work. When I connect the tablet to my PC it constantly disconnects so I cant do anything that way.
[General Questions and Answers] Sparkrite:
Hi, first off, what tablet are we talking about here, is it the one you linked to above (Surface Pro 3 - 64GB / Intel i3) or the HANNSpree HSG1279 (HannsPad 10.1” HD - T71B) as this thread is only about the latter ?

If is the latter (hannspree) then be aware there are no alternative roms available and the only known working CWM is Fipys re-written CWM linked to on page one of this thread.

I STRONGLY recommend you read and follow exactly the instructions on page one of this thread. If you take the time to read the whole thread then you will see that some people chose , to their peril, to ignore this advice.
[General Questions and Answers] steve30x:
I'm refering to the T71. I've read the instructions and followed them to the T. It was working and after a reboot it failed to work , but I discovered what I was doing wrong. I left the SD card in the tablet and it booted into CWM recovery. When I take out the sd card it boots into the OS. It took two hours of installing 4.1.1 and 4.2.2 from this tablet then remove the SD card to discover this.
[General Questions and Answers] kevinthefixer:
Very strange. Mine have both had uSD cards left in them from the get-go with no problems.
[General Questions and Answers] Sparkrite:
Good one alright, but at least you are back up and running. :)
[General Questions and Answers] steve30x:
I think I discovered the problem. I think I accidently installed CWM onto the sd card instead of the tablet. I just put a different SD card into the tablet and it is booting into the OS again. Also I installed 4.2.2 (update-FW8963-20131219E) again after wiping the tablet completely clean and it seems to be running a lot smoother. han it was with the original 4.2.2
[General Questions and Answers] kevinthefixer:
IIRC [MENTION=5110154]fipsy[/MENTION] reported the same phenomenon on his. Seems to like a clean install rather than an update. Some claim it runs better on 411 also. I never updated mine so I dunno...
[General Questions and Answers] steve30x:
Its a pitty nobody is developing a modded rom for this tablet because it would benefit greatly from a decent rom. I would do it myself but it all sems to be very complicated. The way it is now my Dual Core Acer A500 is a lot faster than this tablet. My A500 is a lot older than this tablet too. I was hoping that it would be better with its quad core CPU. Another question I have is it really an IPS screen? My TN gaming monitor has a better picture than this tablet.

Maybe if enough of us request the Cyanogenmod team to develop the rom for the tablet they might pay attention

It's new to me that if the CWM partition is copied to an sdcard it will boot from there. :)

Does CWM also boot if you turn on the tablet while holding down 'Volume Down'?

I hope it stays this way! Many people gradually experience increasing lags.

I fear there are not enough owners of this tablet to make the development worthwhile.

---------- Post added at 03:21 AM ---------- Previous post was at 02:40 AM ----------

I remebered a user posting a technical reason for the slowdown of this tablet long time ago. His remark unfortunately has never been discussed. After searching for nearly an hour I found the posting from [MENTION=5092402]scr1k[/MENTION] again, it's #605: http://xdaforums.com/showthread.php?p=54188327#post54188327

TRIM is a command for marking unused datablocks in a file system. Normally used on SSDs, it enables garbage collection (http://en.wikipedia.org/wiki/Trim_(computing)). I don't know if it's also used within the android filesystem. It could explain why the system slows down after it has been used for a while. And it would also explain why it runs fast again after restoring the exactly same image that has been used before. If this was the reason, the TRIM support must have been lost from android 4.1.1 to 4.2.2. But I don't know much enough about the internal machanisms of the android filesystem to give a substantial assessment.

This article about the Nexus is quite interesting. It describes our problem: http://www.anandtech.com/show/7185/android-43-update-brings-trim-to-all-nexus-devices

So if TRIM is relevant to the NAND memory of the HSG1279, a loss of TRIM may explain the lags on android 4.2.2.
[General Questions and Answers] steve30x:
CWM Will not boot without the SD card installed.

Its true that trim is needed to keep the nand running smoothly. Its like this for SSD's on a computer too. I have an app that runs trim and trim will not run on this tablet. I've tried it on android 4.1.1 and android 4.2.2. It works on my Acer A500 and my Samsung Galaxy Tab 4 though.

Also I got the links to download the Roms and the CWM 4.1.1. from this forum

http://www.android-hilfe.de/hannspree-forum/491077-hannspree-hannspad-sn1at71-10.html

Its in German but so I don't know what it says but it might come in helpful here
[General Questions and Answers] fipsy:
So if you hold down "Volume -" while booting without sdcard, the HANNspree stock recovery is starting up? Meaning that you didn't overwrite the /dev/block/acta partition with CWM!?

But android 4.1.1 didn't have lag problems. Meaning that TRIM should have been working there. Can you prove this?

I collected those links (as you can see from the similar username :D) and posted them to that forum for those who have problems with english language. But all these links have been posted before somewhere here in this thread.

Perhaps I should post this collection here, too. :)
[General Questions and Answers] steve30x:
Yes. It won't boot into CWM unless the SD card is inserted

Download LagFix (fstrim) Free

https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix&hl=en

and Mount /system (rw / ro)

https://play.google.com/store/apps/details?id=com.beansoft.mount_system&hl=en

Runt Mount /system (rw / ro) and mount the system as R/W then Run Lagfix and see for yourself. Trim is not supported in both 4.1.1 or 4.2.2. There must be some other reason that there is no lag issues with 4.1.1 and 4.2.2 has lag issues. My guess is the CPU driver wasn't written written properly for 4.2.2.

What my biggest problem with this tablet is I seem to be charging the tablet more often than using the thing. The battery drains extremely fast with this tablet.
[General Questions and Answers] fipsy:
That's really curious! So you are able to boot into Stock Recovery without your sdcard inserted and into CWM with sdcard inserted? Two recoveries in parallel. Nice! I didn't know that this is possible. It's interesting for those who do not want to replace their Stock Recovery with CWM.

Maybe after more than one year we have finally found a solution to this issue?! Can anybody who uses 4.2.2 and suffers from lags please test this? Would be really great!

This would mean that installing the LagFix has no effect. So it's quite important to test this.

This is also an issue with 4.2.2. Sometimes those drains also occur on 4.1.1 but much less often.
[General Questions and Answers] kevinthefixer:
fstrim is a standard Linux command-line utility. It was carried over into Android IIRC starting with 4.2, but requires a kernel tweak also. It works on my Asus TF700 with 421. My guess is that the kernel used on the Hannspad isn't compatible. Lagfix is just a GUI frontend for the command-line tool.
[General Questions and Answers] steve30x:
If somebody posts a download link to the latest T74 rom I will see if I can port it to this tablet. I'm going to do some experimenting with different roms and see if I can port something better over to the tablet. Also I've disabled the Google play store and google play process which made a big difference. The tablet runs a lot smoother now.

EDIT

I got Cyanogenmod 10. and 10.2 installed on this tablet (The T71) but the rotation or wifi doesn't work. If I could find the drivers for these it would be start. Cyanogen mod 10.1 is android 4.2.2 and is a whole lot faster than what came with the tablet. Maybe if I could get the drivers from the original rom installed with Cyanogen Mod 10.1 the wifi and rotation might work. I don't know how to extract and reintegrate the drivers yet so I will spend the next few days reading up and learning how to do these kinds of things. There is hope after all. (Maybe)

This is where I got the instructions to install Cyanogen mod (The first post) The screen is stuck in portrait mode so its not much use even without wifi.

I was thinking about this question earlier, I would like to eventually port CM11 and maybe TWRP to this tablet in the future.

I don't have much experience with Android development, but I think the drivers are in the kernel image.

EDIT: Looks like they released the same model but with a 4.4 update:

I cannot find any source on their website, correct me if I am wrong but under the GPL they should release GPL source.

[General Questions and Answers] Sparkrite:
Unfortunately as far as I can see the T74 is still unrootable and therefore it is not possible to send a rom image.I have it for 4 weeks now and I must say it is a vast improvement on the t71.
[General Questions and Answers] steve30x:
Unfortunately my T71 is dead kind of. I used it for less than a minute this morning. The battery was at 20% and in less than a minute the battery went to 15% then it shut down at 14% and will not boot up. The only thing it will show now is the charging symbol with the battery icon and the green filling the battery. I only got this tablet last thursday so I can return it to the store where I got it. I think my tablet was dodgy from the beginning anyway because if I atemted to reboot the tablet when the battery was below 35% it would just show the battery low symbol on the screen and not boot up.
