Thanks Kevin. I will give that a try. As far as I know the older version of the tablet (with rubbish specs) came rooted from Hannspree. Once I have root access I will be happy until some sort of Rom comes along that I can try to port to it. I will test it for an hour or two and see what it performs like then I will report back here when I get it. I will also do a video review , overview and unboxing of it but better than the review I done of the T71.

Yikes! That sounds like that 4-letter word that starts with W and ends with ork. Not that we don't appreciate it, especially since as you say there isn't much out there on this tab. But I'd sure be too lazy to do all that.
[General Questions and Answers] steve30x:
If its anything like the T71 than it will be a nightmare to work on because it was very easy to trigger the DRM on the tablet so what should have taken a few hours to do usualy took days.
[General Questions and Answers] steve30x:
I've been in contact with HannspreeUK on facebook and they told me that they don't intend to update the 2015 Hannspree Titan to a 2015 OS. It will stay at 4.4.4. When I asked if they will supply the drivers so we can port marshmallow to the tablet this is the answer I got

[EDIT 2] I replied to them with this answer

And just this very second I got this answer. It might be good news to us after all
[General Questions and Answers] steve30x:
The Hannspree Titan finally got shipped to UPS this evening. It probably wont get out for delivery until early in the morning so the earliest it will arrie here is Thursday Afternoon or the latest Friday afternoon.

[UPDATE] The tablet arrived a few minutes ago. I've had a little play around with it and it seems to be fast. The screen isn't the brightest though. I've just set the runtime from Davik to ART and I'm waiting for apps to optimise. I'll have to put it back in the box though because I am doing an unboxing and over video.

I have noticed that the Storage is divided between Internal Storage and NAND storage too. I just hope its not like the T71 where it installs the apps into the internal storage because theres only 1.96GB of internal storage available. They don't have any bloatware installed either. Its just standard android 4.4.4. Also the tablet is very heavy

I'll report back when I have apps installed and I'm after using the tablet for a day or two. (I'm not sure if I should start a new thread for this).

Thanks very much Kevin. Kingoroot worked first go.
[General Questions and Answers] kevinthefixer:
I don't think I'd bother with a new thread, unless you plan to do some serious dev work like you did with the 10-incher. Which might be a good idea, Lollipop has some serious advances over KitKat. I'm sure the SN1AT71 would be a much better machine on Lollipop, especially if combined with the F2FS filesystem on the /data partition. But that's not likely to happen.
[General Questions and Answers] steve30x:
I don't think I will be doing anything with this tablet. I am already very frustrated with it. Hannspree done something with it in a way that you cant access the recovery menu. When I try to access the recovery menu all I t is the android robot lying down and it says no command but options to do anything. Also the Super User app that Kingoroot installs is absolute rubbish. Only a handfull of the apps that require root get root access. For instanxce Xposed installer and Luckypatcher don't get root access. All attempts to install SuperSU fail too. It also has that horrible boot up bug the T71 has when it refuses to bootup. Right now it has over 25% battery and its refusing to bootup.

I done some benchmarks with it though. It scores higher in ANTUTU than my Galaxy Tab 4 10." in everything but storage. The storage has a lower i/o speed. It scored just slightly faster in Quadrant than my Galaxy Tab 4 too. In Quadrant it scores 4760 and 25 147 in ANTUTU.
[General Questions and Answers] steve30x:
Ok I edited the buildprop and now the tablet will not boot. I am stuck big time until I can find a buildprop or find a way to extract the buildprop in the state the tablet is in now.

[edit] I'm one step closer. I got the buildprop through adb but I can't get it to push back because the /system/ folder is read only. Do you guys have any Idea how to rectify this? I've done a factory reset / cleared cache and tried to CH MOD the directories through ADB but I get the message

Unable to chmod /system/: Read-only file system

I've done ADB shell then SU then tried copying the build.prop and CHMOD the file / folder. I've been at this with the past four and half hours but I'm getting nowhere. Is there a way to extract the rom and reflash it with the build.prop fixed even?
[General Questions and Answers] kevinthefixer:
Steve, did you try to umount /system in adb shell, then mount it with a -rw argument? there's a way to do that in one line but I forget what it is. I should either do a lot more command-line stuff or a lot less, one or the other!

Your recovery issue isn't really an issue, you just have a fairly standard OEM recovery reporting that it has nothing it can do. If, however, you can find Hannspree's firmware, you should be able to copy it to /data/ with adb (do you still have adb access?), boot into recovery and it will flash it. You might look around to see if anyone has ported CWM or TWRP recovery to that tab, that would solve a lot of problems if it's possible to fastboot flash one of those. You didn't perchance create a backup with ONandroid, did you? Saved a tablet of mine once, I did that before CWM was available for it. Had to restore it later on, pulled a similar boner to the one you just did.

I'm not surprised by your benchmarks. I do a lot of work with Asus Transformers, and they are similar: whiz-bang processors but terribly slow flash memory chips. They love f2fs, and they love fstrim.
[General Questions and Answers] steve30x:
I have no idea how to unmount the system with adb but I tried multiple ways to mount the system as read / write but it all failed. I looked up all sorts of ADB work arounds and most of them required my tablet to be in the OS and USB debugging enabled , but as I can't get the tablet to boot I am stuck right there.

As for the recovery I discovered that what I was seeing was a smoke screen but pressing the down volume button the recovery options showed. So I ran system restore which didn't help because I messed up the build.prop.

I also searched for the Hannspree firmware but I can't find anything.

I did find another thread here on XDA with some people who ported TWRP to tablets with the RK3188 chip on it and they posted a generic image but it fails becauise its not signed properly. I'm going to ask over there if they can create some sort of TWRP or if they can help me create one. I'm not that much up on this kind of stuff and because its eight months ago since I worked on the T71 I am after forgetting most of what I was doing.

Also I tried to boot the tablet to fastboot but its not possible. When I try to boot into fastboot the tablet just reboots.

No I made a massive noob mistake and didn't make a nandroid backup. I should have done so and it would have been able to rectify the problem . If I can get TWRP onto this I am hoping I can mount the system folder with read / write enabled and push the build.prop to it. Until then I have a big paperweight because I can't figure out how to fix it.

[EDIT] I just thought of something. Would it be possible to try to force the tablet to boot into CWM or TWRP from an SD card? I have a 32GB SD card in the tablet.

Thanks CXZa. I will have a look.Yes the T71 is awful compared to the Titan. I wouldn't be putting the effort into fixing it if it was as bad as the T71 but the Titan is so much better. Theres a few small things wrong with it but they are only minor things.
[General Questions and Answers] kevinthefixer:
[MENTION=5213414]CXZa[/MENTION], good to see you chime in. You're more likely to help Steve out than I am...

Steve, I'm still unclear as to whether you have adb access with the tablet in its present condition. Can you get a return from "adb devices", either when trying to boot into Android or when in recovery? If so then

adb shell

mount #should return partition IDs and mount points

su

umount /system

mount -rw mmcblk0p(whatever it is on this tablet) /system

I'm not sure if mmcblk0pwhatever is correct but the mount command should tell you. [MENTION=5213414]CXZa[/MENTION], maybe you could check my syntax? I'm really rusty as far as CLI work goes.

I can't understand why the Hannspree tablets are such a pain to work with but my Galaxy Tab 4 10.1" is so much easier to work with. If this was my Samsung tablet it would be fixed by now.
[General Questions and Answers] steve30x:
UPDATE thanks to Oma on ARC Tablets I got CWM installed onto the tablet. This will make my life a whole lot easier in fixing the tablet.

With that I got it to boot again.
[General Questions and Answers] kevinthefixer:
Excellent! I still do not understand the root problems you had (have?). KingoRoot used to install SuperSU by default. Anyway glad you got it going. And with CWM installed you can shoot a Nandroid. Score one for our side!
[General Questions and Answers] dr_bowtie:
I also bought this tablet at walmart when it came out. Out of the box it was snappy and worked well but it got 2-3 updates right away and I ended up doing them a day apart and after each one the tablet got worse and worse. To the point I quit using it.

Originally I bought it for a work tablet to use in an automotive shop doing ECM diagnostics with a bluetooth dongle (OBDII) and it did ok but other than that it was very laggy after the 4th update. I've watched over this thread since and I decided to get the tablet out today and was surprised by a still full battery after sitting in the cabinets for months.

I just flashed this CM 10.1 fresh from stock no issue. So far it is less laggy than it was but still not out of the box new feeling. but hey it might be usable.
[General Questions and Answers] steve30x:
I fixed the root problem. There was a setting in the build.prop stopping adb root access which I changed. I removed kingoroot and installed supersu through cwm and now I have full root access. Before I changed the build.prop setting I wasn't getting full root access even with supersu. I also done a nandroid backup straight away , but I am going to attempt and pull the rom from the tablet and see if I can get a better rom installed. I'm not saying the rom installed is bad because the tablet is really really fast. Its actually faster than my Galaxy tab 4 which I thought was fast but the functionality is very limited. I'm not even getting a reboot option with the rom. I'm not going to touch anything for a day or two though. I have enough frustration to do me for a few days now. I know over at arctablet they have CyanogenMod for tablets with similar specs so I might be able to do something. Saying that though breaking the tablet again is kind of putting me off

---------- Post added at 08:03 AM ---------- Previous post was at 08:01 AM ----------

Yeah I gave up on this tablet over six months ago. It was good until the updates came along. Then it was just horrible to use.
[General Questions and Answers] kevinthefixer:
If you need a reboot option on a stock rooted ROM you can install ROM Toolbox Lite. It's free and includes a few other goodies like a terminal emulator.
[General Questions and Answers] steve30x:
I have an app called quick reboot which has the options to reboot , boot to bootloader or boot to recovery. I had that rom toolbox app before and uninstalled it on my other tablet when I didn't need it anymore , but thank you for reminding me about this.
[General Questions and Answers] dr_bowtie:
I have used Flashify for rebooting to recovery and bootloader on various devices and installing TWRP. I was hoping they had TWRP for this device but I am not finding it. I guess I can just leave the CWM zip on the device and use it if needed. I am hoping after a few cycles the rapid battery drian sorts itself out. It drops 20+ % in a few short hours sleeping. That could be because wifi maybe on while sleeping. Other than that it seems good.

EDIT: Steve, do you remember how well the 4.2 AOKP works over the CM 10.1? I just found the link you posted on the AOKP and I may try it. The CM 10.1 is pretty slim and seems to work better than the stock rom.
[General Questions and Answers] steve30x:
I can't remember if there was a CWM for the tablet.

Which AOKP are you refering to. I think I made one with extended system partition which ran faster than Cyanogen Mod. one of the problems with the tablet with the tablet was that Hannspree had a weird setup with the partitions and any apps you install got installed to the system partition so eventually the tablet slowed to a crawl when you had too many apps installed.
[General Questions and Answers] dr_bowtie:
I got the AOKP 4.2 from this thread. I believe page 92-96 somewhere in there.

EDIT: This is the one http://xdaforums.com/showpost.php?p=58632433&postcount=915

I first nabbed the CM 10.1 from page 111 or there abouts and yest there was a CWM portable. That was in the instructions for installing the nandroid back up of CM 10.1

I nabbed the AOKP 4.2 back up last night and may try it tonight. The battery life on the CM 10.1 seems horrible. I installed it on a full charge and just over a few short hours, while the tablet was sleeping, it dropped to 75%. Using it over an hours it dropped to 60% just browsing the web. I left it over night sleeping and woke it up 8 hours later to 17% and WiFi stuck at trying to turn off. It needed a reboot to regain WiFi.

I just switched WiFi settings back to Always On and turned off Notify of open networks.

This tablet would easily go a week sleeping and still keep a healthy charge and months off and keep full. Seems CM is using battery for something over the stock rom?
[General Questions and Answers] steve30x:
It depends on the apps you have installed. I have a 10.1" samsung Galaxy tab 4 here and with a few apps I use all the time it will drain the battery to 75% from full charge overnight too. Also with stock rom on that tablet I found battery drain to be awful. I also have a Samsung Galaxy Tahb 4 7" with the bare minimum that I use mostly as a remote control ofr KODi and after three weeks it will be barely drain the battery if its not used. The new tablet I got though is a different beast. It won't even last a day on full battery and it takes seven hours to charge. The T71 doesn't have a Lithium Ion battery either. It has a Lithium Polymar battery which is a terrible battery technology.
[General Questions and Answers] dr_bowtie:
It's just weird on the drastic change on how it does. I've not seen a tablet lose 20% in 2 hours while simply sleeping. I may let it cycle a few times and see if it's just the typical way CM is calibrating the battery stats. I noticed on a reboot the battery went from 17% to 23%. weird.

Only apps I installed were ES File Manager and SNES9X just for testing. Not even using half of the alotted storage. Last time I did install or move stuff to the SD card. That helped.
[General Questions and Answers] steve30x:
Ok heres what you could try. Maybe CyanogenMod is not calibrating your battery right. I am using these apps when I install a new rom and they make a big difference. Make sure you fully charge the battery before using the apps first then let it drain fully twice and it will calibrate fully.

https://play.google.com/store/apps/details?id=com.nema.batterycalibration

https://play.google.com/store/apps/details?id=com.ignisoft.battery.calibration

Also I use this app to show my battery percentage in the top of the screen task bar and it shows battery heat and battery health in the app.

https://play.google.com/store/apps/details?id=com.darshancomputing.BatteryIndicator

You will also need SuperSU to get full root access for the battery calibration apps to work

[General Questions and Answers] dr_bowtie:
The CM 10.1 is rooted. First thing I always do is turn on the battery percentage.

I left to do some running and back back and the tablet was off. It was at 13% when I left. by my watch it went from 100% to off in 12 hours with 10 of those sleeping. thats a pretty good drain just sleeping. I'm charging it now off and going to test it again.

Not a real big deal it's just giving me something to tinker with over the holidays. For regular stuff tablet wise I have a Samsung Note 10.1 1st edition

I'm going to start a new thread for this tablet.
[General Questions and Answers] dr_bowtie:
I've been playing around with the sn1at71 with the CM 10.1 installed from a back up and since first installed the wifi was dropping. It would show full signal but be gray and sometimes go blue and then back gray. After the tablet shut off from battery drain after 8-10 hours I did a full recharge in the power off state.

Once i booted the tablet I decided to boot to recovery and wipe cache and dalvik and just reboot. I did the same as before and in the stock recovery i flashed the cwm zip for cwm recovery and on a slip I rebooted the tablet instead of doing the wipe. So on another reboot I decided to try the portable twrp and it booted just fine so I did the permanentize and I have now twrp recovery.

From there I just did a cache wipe and dalvik wipe and did NOT do a factory reset. Upon reboot it appeared it did a full reset of CM 10.1? it was like I installed the back up fresh.

So what would have happened if I did the factory reset too? would it go back to the stock hannspree firmware or was this just a fluke?

After going back and reading the thread from page 80 it may seem I did not want to permentize twrp if I want to swap back ups? not sure on that. But I did have the same battery drain right out of the fresh back up. It went from 100% down to 95% before I could get through the set up.

Turning Wifi completely off stopped the drain. it's been 2 hours and hasnt dropped any. I'll leave it to morning and test it then I am going to shut it completely down and leave it for a day and plug in the charger to see where the level is at. I prefer to leave twrp on the tablet but if I cant restore the AOKP back up to try I may have to figure out how to flash the stock recovery back. I do have the latest stock firmware as well.....

I dont know of anyone still using this tablet to say what rom works best with less issues and battery drain.....
[General Questions and Answers] steve30x:
When you do a factory reset and wipe it will just wipe the data and you will have a clean install of the rom thats installed. It will not roll back to the factory OS unless you reinatsll that rom again. Also from what I can remember the best rom would be the 4.2.2 rom.
[General Questions and Answers] dr_bowtie:
The issue was I did not do a factory reset. I just did a wipe of the cache and dalvik but it acted like it was factory reset as it started all over from a fresh install. So far so good this morning it had no loss of battery over night with wifi off. I made a back up of the simple install and I plan to make a back up of my full install with all my apps installed. Would be nice to open the partition but I dont know how to do that easily and reading about it here seemed confusing to me. Need and app or something that would just resize the partition. or something I could just flash that would do it automatically.
[General Questions and Answers] steve30x:
The best thing to use for backup is Titanium Backup. I've used it for two years and its never let me down. As for the wiping , I really have no clue about that. I haven't used the T71 with over nine months. It could be a bug with TWRP.
[General Questions and Answers] CXZa:
The TWPR says what it's doing. No such bug AFAIK. When you erase dalvik it will say about finding

new apps etc. but the data should have stayed if data wasn't erased.

You can switch roms quite easily using portable recoveries. Just don't restore the recovery

partition of these backups if you plan to permanentize. The recovery used in them

might cause some problems. Otherwise portable versions should work over it just fine.

I'm probably wrong but I have some faint memory about that the wifi turn on/off options were backwards.

But it might have been a different tablet and ROM altogether. But I think there is option that put airplane

mode on when the screen sleeps...

There is already a fw file for sn1at71 that has a bigger data partition I think.

Was it you Steve who made it? ;)
[General Questions and Answers] steve30x:
Yes I created a firmware where the main partition was much bigger to allow more apps to be installed.
[General Questions and Answers] CXZa:
Though it could be easier for bowtie to adjust the partitions himself than to find that file.... :P

So, how is the Titan then? My link wasn't useful I guess. They just have the same rk chip.

Found some developers doing firmwares for Hannspree but not this new one yet.
[General Questions and Answers] steve30x:
The Titan is a good tablet but I am having an issue with it at the moment. It only sees 3GB of the 16GB storage. The internal NAND which it calls external_SD won't mount for me. Its replaced my Galaxy Tab 4 10.1" though. Its every bit as fast with a better looking screen and I love the screen size. The two biggest drawbacks about its size is I can't find a universal 13.3" tablet cover or any sort of cover and its very heavy. My 24" computer monitor is lighter than the tablet.
[General Questions and Answers] dr_bowtie:
I'm confused? I've already permanentized twrp. So are you saying that I cant "restore" that CM 10.1 or AOKP back ups without issue or I need to not flash the recovery when it flashes the back up?

If so how can I flash the back ups back and forth as i please without reflashing the recovery image? I am not very versed in flashing stuff. But I can follow a guide. My OnePlus was the first thing I ever flashed and that was to unlock the bootloader to flash twrp but other than that I am still on the stock rom. My Galaxy S3 I flashed CM but thats pretty much the extent of my experience. Other than the guide here for using the portable cwm flash tool and flashing the CM 10.1 back up.
