Success, permanent 1200Mhz in rom 4.1.1!!! (someone test in 4.2.2, never tested this way in that rom)

Here is the steps:

1) Download Kernel Tuner from Play Store

2) Open it and click on CPU button

3) Click on "Link Cores"

4) Move the "min" slider to the max 1200Mhz (you will still see 1008Mhz on top yet)

5) Go back and now click on Governor button

6) Open the Boost option (which should be 0) and set it to "1"

7) Now go back to the CPU button and set the "min" slider to the minimum.

8) Enjoy your 1200Mhz!

Attached some screenshots and didn't used Antutu as benchmark to prove the 1200Mhz are working globally.

Happy new speed! :victory:
[General Questions and Answers] Sparkrite:
Unfortunately, not working on 4.2.2, or at least I cannot get it to work.

"Boost" option will NOT change from 0 to 1, on any of the governors :(.
[General Questions and Answers] fipsy:
One more reason NOT to update to 4.2.2! If you don't need the multiuser options (I don't!) you should only use 4.1.1! It's much more smooth and convenient. Not only because it supports UMTS surfsticks and doesn't have lags. :D

And if you need multiuser - buy a second tablet! :p It's not that expensive...
[General Questions and Answers] fipsy:
GREAT!!! This really works! The overall performance of the tablet is noticeably a lot better than before! One more reason to stay with Android 4.1.1!

What are the steps to downgrade back to 4.1 on this device my device is already rooted
[General Questions and Answers] fipsy:
Download the CWM Backup that is referenced here and restore it with CWM Recovery. Of course all your data are lost after this procedure.

You could always follow the step by step guide in the first post of this thread

or some people have had success with Cydia Impactor..............http://www.cydiaimpactor.com/

I have used Kingo successfully but there were rumours about certain data collection while

rooting phones but no issues with tablets..............http://www.kingoapp.com/

Are you sure it's from February the 26th? I only know of an update from 19th of February. Or has there been another one from 2/26?
[General Questions and Answers] lieffring:
Kinggo works great
[General Questions and Answers] Corbu78:
I think so...but...

Hi...I think it's from the 26th but i'll confirm that later...because now i don't have the tablet...!

By the way...after i installed the update, did a factory reset in the recovery... ;) maybe that helped...! :silly:
[General Questions and Answers] fipsy:
Would be nice. Thank you!

The question is: For how long will that pleasure last?
[General Questions and Answers] Corbu78:
you're rigth sir! :)

Hi...you're rigth. The last update i received is from the 19th... :D

For now it's working properly...let you know if the usability begins to fail...!

Did you mange to root it by any of the methods I suggested?
[General Questions and Answers] tylergard702:
Hannspree 10.1" HANNSpad 4.2.2 root

Hi all,

Got a batch of these tablets at work for use with students, however our app and settings deployment solution requires root access on the tablets. I have managed to successfully root and install CWM recovery on one of them out of the box, however i wanted to try the update to see if it was any better.

So after trying the update and failing to root following the instructions on the OP, i tried to boot into CWM, soon to realize that the update re flashed stock recovery (I know this has been pointed out, and tbh, i should have been more thorough in my research.) I now have tablet stuck on 4.2.2 which i cannot seem to root and cannot revert to the original version.

Any ideas? I have tried the KINGGO root method and the Impactor method to root however to no avail. I also tried messing about with busybox su and some oter automated root tools, but because the system doesn't allow the chmod command without root privileges, no luck.

Thanks in advance. :D

EDIT:---

Well, kindly disregard this entire post.

I tried an app that i used to root my phone a little while back called "Root Genius" and it worked a treat.

lol, I have been researching how to do this since Thursday and i figure it out the minute i ask for help.

Thanks anyway :)
[General Questions and Answers] fipsy:
Though you solved the problem by yourself, the easiest way would have been to use adb shell. On Android 4.2.2 adb shell automatically offers root access. So it's no problem to flash CWM recovery and after that with CWM use a lot of rooting methods like SuperSU zip.
[General Questions and Answers] Corbu78:
:P...yiakes....

Yes ..i'm a nerd and still haven't tried....sorry sir!

Thank you!
[General Questions and Answers] tylergard702:
Thanks for the tip, however it didn't seem to for me :/ chmod wouldn't function, nor the mount command so i could not edit any of the root file system due to lack of permissions. I was in quite the pickle :L all sorted now though. Thanks anyway.
[General Questions and Answers] piaaf31:
Root is no longer available in the last 4.2.2 update, even with adb shell.

After I tried to make the update, I was stuck with stock recovery, and no way to get superuser permission. So first I flashed previous update 20131319, then got root access back via adb shell, pushed CWM using cat command, and then flashed the nandroid backup I had made just before I begin to mess up with the tablet.

So it works again now and I think I'll stay with this config, because it works perfectly for me.

For information, I installed PurePerformance X which changed radically the device's behavior.

I'm sorry for not having talked of this earlier but I have very few time to deal with my tab, and writing in English is a bit heavy for me.

I've tested PurePerformance for a few weeks now,and I'm fully satisfied.

So, to make it short, here is my config :

- Firmware 4.2.2 build 20131219, rooted with fipsy's method (see first post)

- SuperSu updated on the playstore (doing that implies updating su binary ; I don't think that step is necessary)

- Of course CWM Recovery 6.0.3.3 by fipsy

- PurePerformance X Mod (I used the version for stock rom), installed with CWM

http://xdaforums.com/showthread.php?t=2360670

In addition :

I use Greenify, and put nearly all my apps in the list for hibernate,

I converted YouTube into a userapp with TitaniumBackup to be able to put it in the Greenify list.

I freezed the Software Update app with Titanium to be no more bothered by notifications.

And of course, disabled most of Google sync (kept only Calendar and Google keep because I need them.)

Et voilà ! Everything works fine ! I hope it will be helpful. Enjoy ! :)

Now I'm longing for a fully-working version of CM10.2. unfortunately, I haven't enough knowledge to do the work, but if somebody has time to deal with that, it would be great.

Wouldn't it be possible to find them in the stock ROM ?
[General Questions and Answers] JimboJoe:
When comparing the initial Hannspree recovery, and the TWRP Recovery from Christain Troy (I imagine it's the same codebase as CM), here are the libs only on the Hannspree side:

bt_drv.ko

camera_gc2035.ko

flash_light.ko

hdmi_setting.ko

tsd_block.ko

ctp_gslX680.ko

gsensor_kionix_accel.ko

wlan_mt5931.ko

The three last ones seem to be: touch driver, gsensor, and wlan

If you look at

http://www.slatedroid.com/topic/79953-cyanogenmod-1010-unofficial-on-crystal-2-quadcore/

there was a manual procedure that "may" apply for the gsensor drivers, given you take our gsensor_kionix_accel.ko

Now you need to find that files in the stock ROM, and hope they are actually compatible with the CM kernel version...

fipsy can correct and/or complete my raw hypothesis...
[General Questions and Answers] fipsy:
Thanks, this is a very important information! Fortunately the second 4.2.2 update from February 2014 doesn't replace the recovery (as I was told - didn't try it). So if you want to install the second 4.2.2 update from February 2014 and want to retain root, you have to make sure CWM recovery is installed before you make the second 4.2.2 update.

It would also have been enough to deactivate the Software Update service in App-Settings (for those who don't use Titanium).

Yes - if the kernel is already working and only some external modules are missing.

---------- Post added at 12:41 PM ---------- Previous post was at 12:31 PM ----------

:fingers-crossed: Thats the point. What is the module tsd_block for? Some drivers may probably be built in. This is the critical point. Not all hardware drivers are external modules, some maybe built into the kernel. But there is nothing to be said against trying it!
[General Questions and Answers] piaaf31:
Thanks. Actually, the problem was that the second update from february did not work at first. It stopped during the process with an error, and the next boot stopped on Hanspree logo.

That's why I re-flashed first 4.2.2 update from december, then gave a second try to the second one (which worked this time), but I didn't think about installing CWM between these two operations.

Anyway, now it works fine with first 4.2.2 from december + my few tweaks, and so there's no point for me in updating to february 4.2.2 :)

I'll give it a try when I have time and let you know...

Thanks a lot...
[General Questions and Answers] fipsy:
Now I got into a very curious situation with this tablet I've never heard of before:

I was updating some apps from the playstore (including YouTube). But the update of the YouTube app didn't finish. Just always "downloading". The tablet was working fine except this not finishing download process. So I decided to reboot the tablet. And after this it didn't start again! Just the yellow/green HANNspree logo and nothing else. Even after 2 hours of waiting nothing more happened.

So I rebootet into CWM recovery and restored a backup from last week. Restoring worked fine. But after rebooting I had the same problem as before: Nothing happened after the HANNspree logo showed up. Meanwhile I tried to wipe all partitions except recovery, restore a lot of other backups including the 4.1.1 backup uploaded from ismaeloelo and I also installed the stock 4.2.2 update from 19th of December. Always the same: No chance to boot into android, just the HANNspree logo. I'm just able to boot into CWM recovery. Looking into the adb shell everything seems to be fine: The /system and /data partition looks good, no error, nothing in lost+found. But the tablet won't boot!

To cut it short: I'm completely stumped (and this really bears a meaning ;). I think I will mess around a bit with the actions tool. But perhaps I won't get around an RMA...

What maybe interesting: I included a former YouTube update into the system ROM using Titanium Backup to save system memory. Maybe this is the reason for the device being bricked after trying to update the YouTube app using the Playstore. But I don't know who exactly is to blame for it.
[General Questions and Answers] Sparkrite:
At this stage, I would be starting to suspect it could be a hardware problem, or at the very least a partition error.
[General Questions and Answers] fipsy:
I also thought about a partition error. Because if it was a hardware problem I suppose there should be some other additional problems. Especially because it suddenly appeared when everything was working fine. Maybe rebooting while the update was running caused some corruption at important points. What's also very strange: If I plug in the power adapter no battery animation appears though the device is being charged. And sometimes even the HANNspree logo doesn't appear if I turn on the device. Only the display background light goes on. As some other users reported before. But they could revive their tablet using CWM.

Do you know where the hardware partition information is stored? Probably in NVRAM? And can it be read out somehow?

Edit:

My god! This is extremely weird! The tablet was running again and I don't know why! Seems to have been the same error a lot of people reported before. But here with me the error is very extreme. Because of my problem today I had the USB cable and the power adapter always pulled in together for a lot of hours while I was testing many different things. Once I pulled out the USB cable and waited a moment before I pressed the power button to turn on the device. But instead of turning on suddenly the battery charging animation appeared! I was very surprised because this had not occured for about 20 hours. I didn't do anything and waited. While charging the animation showed for about one hour the battery being deeply discharged. When it finally had been charged to about 40% I tried to turn on the device. And as I somehow expected - android was booting again (the 4.2.2 version I installed before)! So connecting and disconnecting the USB power cable and the power adapter frequent times over a couple of hours can definitely revive the tablet.

But now there is a thing that is that strange that I can't believe it: After the device was booting again I restored the CWM backup I made last week. And believe me: Now the device won't boot again! But if I apply the android 4.2.2 update from 12/19/2013 the device is booting again. It only works with the update from 12/19 but with no CWM backup that I restore. Isn't that weird? I never had such strange behaviuor before in my life. :(

But one thing we now know in addition: If the HANNspree logo appears and nothing more is happening, this can be due to a deeply discharged battery with very low voltage! The problem is that the device isn't charging the battery anymore if it's deeply discharged. Maybe the best thing is to plug in the USB cable and power adapter together and let the tablet alone for about 10 hours. Then disconnect the USB cable and press the power button for about 3 seconds. If the battery animation appears charge it to about 40% and then try to turn the device on. Maybe this helps others with the same problem.

[MENTION=5110154]fipsy[/MENTION] I reckon your tablet is haunted. :)

Glad to hear its back working though, but VERY strange re: the CWM backups not working.

See, I told you it IS haunted. :) :)
[General Questions and Answers] fipsy:
I think it's simply broken. A hardware damage. If I install Android 4.2.2 the tablet is running at the first sight, but the G-Sensor isn't working anymore! Also calibration is useless. I did a lot of factory resets and update-installations as well as restores of several backups. Always the same: 4.1.1 isn't running, 4.2.2 is running but without G-Sensor. Furthermore on 4.2.2 I once had the problem that the touch display wasn't working: my touches had no effect. It seems to be obvious that these errors are associated with a memory problem. Probably 4.2.2 uses other parts of the memory than 4.1.1 and these parts don't fail. This seems to be the only explanation. Fortunately I have an actual backup of the system and sdcard. So RMA is without problems. I restored the 4.2.2 update from 19th of december and the original recovery.

One thing is very thought-provoking: I applied the 1200 MHz patch Omegadrive reported about two weeks ago. It maybe by accident but it's noticeable that only a few days after having the device bursted to 1200 MHz the G-Sensor is broken and also parts of the memory. So maybe it's not a good idea to boost the device to 1200 MHz and perhaps HANNspree blocked this on their new releases in knowledge of the technical problems this may cause!?

Edit:

Today I noticed that the camera also doesn't work anymore! If I start the camera app a "Camera error" appears: "Can't connect to the camera". So this really is a hardware damage. The tablet laid on the table making app updates when this happened. So maybe this damage is really associated with boosting the device to 1200 MHz.
[General Questions and Answers] Sparkrite:
Sorry to hear you are having all this trouble with your tablet, any advancement today or is it totally bunched?
[General Questions and Answers] fipsy:
Not totally but the problems persisted. I placed an RMA order and the courier picked it up just a few minutes ago. We will see what happens next. ;)
[General Questions and Answers] Sparkrite:
Ah right, at least that's something, keep us informed as to how it pans out, please.

Cheers.
[General Questions and Answers] Bluze:
That's really interesting. It's the same behavior I was getting when I said I was going to return it the first time. Nothing but a backlight, then nothing but a logo. As you said, no battery charging animation. Then it "magically" started working again. I think Sparkrite is right. They're haunted! :D
[General Questions and Answers] fipsy:
I think there is more than one reason for this behaviour. Maybe android 4.1.1 verifies the sensor and camera while booting the kernel. If this tests fail the HANNspree logo stays forever. And maybe Android 4.2.2 doesn't verify this and even starts if hardware is missing or not accessible. This could explain the different behaviour in my case where some of the hardware was definitely broken. In a german HANNspree forum there are two other users that also had a broken G-Sensor and camera.

Whereas your G-Sensor and camera have still been working after you've had this problem... It's weird but there certainly is a natural explanation to this problem. :laugh:
[General Questions and Answers] fipsy:
Today I got my tablet back repaired. First: The HANNspree reparation service is excellent! Five stars! On monday the courier picked it up and on thursday he brought it back repaired! Three days for repairing including shipping is the fastest I have ever seen.

I got back my own tablet. I could verify this by the display protection foil that was still there. Externally nothing indicates that it has been opened. But maybe they are able to open it without any damage to the body.

I immediately rootet it, pushed CWM recovery and restored my old 4.1.1 backup from last week. And it perfectly works! So it's proved that a non working G-Sensor or Camera causes Android 4.1.1 not to boot anymore. But 4.2.2 is still booting even if camera and sensor are inoperable.

And it's also proved that a hardware defect caused this behaviour. Quite interesting. But I'm not sure if boosting to 1200 MHz may have to do something with this problem. Because it occurred just a few days after applying this modification. And I'm also not sure if I should boost it again. :confused:

Cheers, Volker
[General Questions and Answers] Sparkrite:
Yes that is good service alright. Glad to hear you have a working tablet again.

But you don't know exactly what was done to it, was there no repair report or anything?
[General Questions and Answers] fipsy:
Unfortunately not! I only got an email from the repair service that they sent it back and two emails from the courier service with an estimated delivery time. But I only got the tablet back and nothing else. No service report, no notice or anything.

Another user who let his tablet repair reported the same.
[General Questions and Answers] Ajsh:
I'm sure you're not the only one that overclocked it. I'm really interested in hearing how the overclocking worked out for other people, because your experience scares me. I probably won't get as good service as you did here in Sweden so I don't want to destroy it:P

So anyone else have it overclocked?
[General Questions and Answers] franzmueller:
Well, i overclocked my hanspad with android 4.1 and kernel tuner. It works pretty good since then and I dont have any problems with the g sensor or the camera.
[General Questions and Answers] fipsy:
Maybe the courier service is a bit slower but I think the repair service will be approximately the same. After I placed the RMA order over the internet a few hours later I got a mail with a job number from novaserve.eu who do the service for HANNspree here in germany. I think it will not be much different in sweden.

I wouldn't call it overclocking because the manufacturer grants the device working up to 1200 MHz on the outer packing. The only thing that's a bit vexing is the fact that HANNspree prohibits clocking above 1008 MHz in the new Android 4.2.2 version. As I know the brother of Omegadrive who opened this thread also clocks his device to 1200 MHz. And seems he has no problems. But I don't know what his brother is doing with the tablet. :D
[General Questions and Answers] ig6677:
No, do not apply!. I've got exactly same story.... after applying boost patch, my daughter's tablet (3rd one ... previous 2 works only 2-5 days....) in about 1 week - black screen and only back-light is working. I restored Android 4.2.2 and got message - can't connect to camera and g-sensor doesn't work also :( ... will call for RMA ...

---------- Post added at 12:12 AM ---------- Previous post was at 12:06 AM ----------

Possible .. the tablet has bad design .... The CPU and flash chip could not dissipate the heat properly ...
[General Questions and Answers] Omegadrive:
I suspect some of them may have a bad design, my brother uses his tablet with his 8yo son and all I know is that he plays games on it like Minion Rush and some others and so far haven't had issues. Also, I don't think OC has anything to do with that issue since the CPU speed only gets to the full 1200mhz when running intensive apps like games, 90% of the time the tablet sits on the lower clocks.

But let's see in a couple of weeks if he reports anything, the tablet has been OC since I gave it to him a month ago.
[General Questions and Answers] mrosebro:
Can't load su

Hi all - first time poster here. I've followed this thread through all 40 some pages (most of it more than once) and i'm very frustrated. I can connect to the tablet via ADB but i can NOT get past permission denied. i can not SU, i can not place SU anywhere on the tablet (besides like on the sd card) and even when i copy the su file onto the sd card, i can not copy it to xbin or anywhere else usable (sorry i'm not being more specific right now but i've been working so hard at this right now my brain PHYSICALLY HURTS.) Every time i try it just says permission denied. I can't even cd into the folders where i need to place su. So maybe there's some step by step direction i missed, or maybe if someone could post a very dumbed down youtube video (i hate to ask for that) i'd greatly appreciate it. because i'm OBVIOUSLY missing something small or stupid that might be obvious to many but not to me. I have successfully rooted and even installed TWRP on my android phone and there are certain things i want to do to my tablet that require root.

I am running latest OTA update 4.2.2

Model SN1AT71 (HSG1279)

i can adb

i can NOT cd /system/xbin

i can NOT mount -o remount,rw -t rfs /dev/block/st19 /system

i can NOT install SuperSU.ZIP from recovery
