I thought that might be what you wanted. Nah I have a newer one, my build is Monday June 26th 2017. I only got mine a few weeks ago it is slightly newer model I15-TG. I did my own boot.img. I posted that long post a couple back about using Android kitchen and the thing about xposed.

I tried that gyro app, I am not getting any readings. But I had this other app for controlling an arduino robot, and that had a function to make the robot lean the way you tilt the tablet. It worked but it was the wrong orientation, like tilting it left and right would actually tilt back and forward. I used it on another Lenovo tablet and it didn't do that.

https://play.google.com/store/apps/details?id=com.freenove.suhayl.Freenove

That is the control app, you don't need the robot to see what I mean, it has a similar visual thing like the gyro app you posted. In the app select the quadruped robot. Then go to 'rotate body' option down the bottom right. Then change from 'touch control' to 'gravity control' up the top right, under the freenove logo. Then you can see the dot move around in the circle when you tilt the tablet. I don't know if that is useful for you.

One other thing, have you seen that post on techtablets by Laura. It's really long. There was a section about accelerometer issues in windows for this tablet, I wonder if these problems are somehow linked. That is the same thing yes? Gyro and accelerometer? Or not?

Lineage would be awesome if you could get it to work! :cool:

Edit: here is the link to Laura's thread on techtablets:

https://techtablets.com/forum/topic/the-big-thread-of-how-tos/
[Android General] brainvision:
hi thanks for your hints, suggestions and for checking my questions..

I know the big how-to thread on techtablets, it was one of my source to write guides here but no, issue on windows and android are indeed different: each system has its own drivers, they are not shared in any possible way.

accelerometer and gyroscope are two different sensors: accelerometer measures the speed of the device when you move it. gyroscope measures the device rotation on 360° perspective. basically.

anyway after asking you to try the app I thouht that even if I had no results from the app I could still use the display rotation feature and that meant the gyro worked. I also downloaded a game that uses gyroscope and I play it normally so it must be some sort of gyroscope manufacturer unkown to the app database, I guess.

about your issue I think you could try to recalibrate the gyroscope sensor: search for play store for apps to do that, the first that come in my mind is the amazing GPS Status & Toolbox. Pretty useless on iWork because no GPS but you can just use the Pitch and roll calibration feature there.. ;)

about Lineage OS 13: well it's amazing! works like a charm, all but camera that has the usual issue of bad/wrong driver that causes the photos to have two green vertical bands on the finished photos. also front camera is 180° rotated. videos are fine. to be honest I never used this device to make photos and videos so not a big deal at all for me! last buty least camera works anyway so video calls should work fine, that is the only way to use camera on iwork, imo

xposed works fine too, using the official rovo89 framework (api23 v87) and not the old (v81) amiduos unofficial porting.

EDIT: I wonder if the firmawre updates was also for TCL variant and what was changed, eventually.. hope someone could reply about that
[Android General] shaun_prawn:
Cool, thanks for that stuff. Will you be posting this rom up on xda do you think? If so, I'm really looking forward to it. I put lineage on my dads old Sony xperia and I really liked what I saw. I wish I knew how to do all that stuff with porting roms. I also don't use the camera at all, it's a pretty crap camera to begin with so it wouldn't bother me in the slightest. I'm surprised that xposed works as normal as I thought the reason it didn't work was due to the x86_64 architecture of the Intel atom processor and xposed only supported x86 OR x64 but not x86_64. That stuff is all way beyond me, I read about it but don't really understand it, I just pretend I do :rolleyes:

With the firmware, my kernel was the same as what was in your guide but the date was different. So does the different date mean it is updated? Or the same but just released later as my device is apparently a different version again. It's kind of annoying having so many variations of the same device.
[Android General] brainvision:
yea different dates of the firmware means updates, indeed. Cube has OTA (Over the air) wireless updates but I never receivd one because I immediately rooted; naturally TCL does not receive update of TD.. the kernel could remain the same but changing only androis system rom stuff. I'm not sure but I think that the kernel is basically the same for all iWork 10 variant

xposed works on LOS 13 because AOSP compilation is builded with a better compatibility mode, rovo89 himself told somewhere that it's easier for the framework to work on x86_64 arch if using AOSP instead of the stock manufacturer firmware.

abnout the ROM, I'm just changing a few lines in the build.prop file so to have Cube iWork instead of Chuwi Hi10 and check everything is still working then I could share no problem, even if nothing of it is my work ;)
[Android General] shaun_prawn:
Sd card problems?

Hi, quick question, do you use an SD card in the cube and if so have you had any problems with it? I have a 64GB Samsung EVO which works fine in any other device. From day one I had problems with it in the cube. It would randomly dismount and say to unmount the SD card before removal even though I was not removing it. Eventually it said it was not formatted properly and I tried to reformat on the tablet and using my PC but it would still say it wasn't formatted properly. I ended up putting it in my old tablet and was able to format it fine. Put it back in the Cube and it worked for a bit but then starts unmounting again.

I was going to purchase another card but have since found some forums of people having similar problems, and they seem to think it happens with anything over 16GB in size, and some people said the slower Class 4 cards have less problems. This sounded a bit strange to me so I just wanted to see if you had a similar thing happening?

Also, how did you go with porting Lineage OS over? Any luck?

Thanks.
[Android General] brainvision:
Hi mate, my personal suggestion is: don't buy other SD card because problem is the Cube not the SD cards!

I had the issues you have and for me was a big issue because I used Link2SD to gain space for apps when I still had Windows too. Often apps moved to SD crashed because the card was removed even if the tablet was on a table and I did not even touch the screen!

I tried with 3 different SD cards, 8 gb, 16 GB and 32 GB, Samsung and SanDisk same results, from Class 4 to Class 10.

When I explained that to my seller it replied after a week: "Please use an OTG or micro USB adapter. This is a known issue for these Cube devices."

Weird thing is that there are users having these issues only or mostly on Windows and others on Android. So if you can borrow sdcard from your friends maybe you could find one working and then buy him a new one (I doubt it but you can never tell) otherwise I would not spend money..

About LOS 13: works fine except camera as we said. But I found another issue that I'm not able to explain: the device never goes to deep sleep, so even when the screen is off there's something running in background at minimum CPU speed wasting battery. It's not related to apps but it's indeed a system service; I did not find a way to kill it. And I tried many things!

If you want I could upload the rom somewhere
[Android General] shaun_prawn:
Thanks

Ah, I see. I wonder how they have not managed to fix this yet. I have the i15-TG which I believe is the newest model. So there have been like 3 or 4 iterations of this tablet and it hasn't been fixed. I can't complain too much, as it was a very cheap tablet and has been very good in terms of performance I believe. Did you buy from banggood.com? That is where I purchased mine. I don't use the windows side much at all, but it has been handy sometimes and I still want to keep it I think. I will probably get a usb to use with it instead.

As for LOS 13, well my battery life is already not too good with the Cube, it drains very quickly when I'm using it for just browsing, maybe 4-5 hours and it is nearly dead. I noticed on windows it did not drain as fast but I think the battery is not so good. My last tablet was a cheap Lenovo Tab2 and that battery would last for days, but it was also quite slow and not enough RAM, browser tabs always reloading and such was annoying. So no need to upload the rom, but thanks anyway.
[Android General] brainvision:
I bought mine on aliexpress; regarding the price I see the whole thing like that: I understand that if you don't want to spend a lot of money there are aspects where you need to lower your aspirations in terms of hardware and software, but not both, otherwise it's loose loose situation for the end user. For example I also own an LG G Pad 7 (something like your Lenovo Tab, I see) that is a totally different device from iWork 10 and that I paid even less (much more less I would say, something like € 70 less); yep it has only 1 GB RAM but when I bought it that was the standard. It still last me 10 hours of screen on time, never suffered from any hardware issue, display is laminated and they updated stock rom from KitKat to Lollipop!!

When chinese devices started to be diffused all around the globe the idea was: they're cheap, they have no update whatsoever, you have no free support (or maybe no support at all) so you should be aware of all those things before buying one. Today the situation changed and apart from support and Android version upgrades devices are much more durable and reliable. It could happen that a company mount some bad component, but the fact that they are still selling them in the same way without fixing them is no acceptable, imo.

So I could not say I will not buy some Chinese device tomorrow, but for sure I will not buy Cube ones!

But we are going OT and I'm pretty sure you agree with me at the end of the day ;)

Anyway about LOS 13 it's a shame that it has the deep sleep issue because I'm doing something like 3 or 4 hours of screen on time with this ROM that is a very good achievement with this tablet. Of course it depends from user usage, if you close WiFi and Bluetooth when you don't use it and don't need notifications, if you have a lot of apps installed requiring device to wake up and update etc etc. And naturally if you don't use the tablet it could completely go to 0% on stand-by. I think I'll should try to reach the original developers of this porting and asking him for suggestions, if any; I fear the biggest issue is the kernel being the one from Chuwi but it could be something else, can't say..

Last but not least: you talked about 4 or 5 hours when browsing etc; did you meant screen on time or just total usage?
[Android General] shaun_prawn:
Yeah I see what you are saying, it's not really good enough that they don't even bother to try fix the issue. And I'm surprised it didn't even get a marshmallow update. But I still really like the tablet overall for what I use it for, pretty much just browsing the net, emails, messaging and ebay. Also I've been using it with Arduino IDE on Windows 10 as I got the keyboard attachment too. It is a little slow to compile sketches to be honest but I prefer it to my desktop as that is not set up in a good workspace area. I think this tablet will last me a good while but if and when I do get another I think I may steer towards a major brand name. Something with good custom rom support. I like playing around with that stuff and modifying devices.

If you can get LOS running proper with the deep sleep that would be awesome. Do you think the devs may be nice enough to lend you their knowledge?

I get about 4-5 hours screen time. That is pretty much just Web browsing, ebay, YouTube and such. So fairly heavy use I guess. I should try check the usage properly from full charge to like 10-15%. To be honest I rarely let it go below 50%, I usually put it on charge once it gets that low. I think it is not good to drain these batteries fully. My lenovo, I reckon I would get close to 12 hours I think. Maybe more. It just lasted ages.

Hi

Thanks for all the useful info on this thread!

I have the newer i15-TG (rooted with my own modified boot.img) and want to increase the Android storage to 20GB.

Kernel: 3.14.37-x86_64-L1-R517 softteam@pdd-build #1 Thu Aug 3 13:01:48 CST 2017

Build: i15-TG_V1.2_2017_0803

Are there Android firmware images available for this version? If not, can I use images from the tablet itself (presumably I would need to do a factory reset first)?

Is official Dual Boot firmware available for this version? If not, what should I do?

Hope you can help.

Many thanks.
[Android General] brainvision:
You should make a comparison about the two variants: check for specs online and compare them. if the hardware is the same no problem at all. Consider that TCL firmware itself is not available and we use the T/TD one.

Also for Windows you could directly install an ISO file like you do on PC, just be sure to take the drivers from techtablets.com; a possible downside by the way could probably be the lost of the activation key (but I'm not sure about that)
[Android General] DaveOxford:
Thanks for that! Had a go using my own images but had trouble flashing system. Will come back to it later and report.
[Android General] brainvision:
You're welcome! ?
[Android General] comfortable:
I would like to know if you have instructions on how to root the newer i15-TG model.

Sorry editing.. Instructions are the same, you could maybe ask him to share his files so new TG owners could use

i15-TG boot.img

Hey someone messaged me about this the other day, here is a copy of my reply to them with links for my modified boot.img and a screen shot of my tablet info, just compare that you have the same kernel and build number. I noticed that a previous poster also had an i15-TG but they had a newer build number than mine. If yours is different it may not work. For example I first tried to flash the provided boot.img from this thread which was not for the i15-TG and it worked but I did not have auto rotate working.

Original message:

Hi, yeh no problems. Just check you have all the same kernel and build number as my tablet before you do it.

Here is a link for a screenshot of my tablet details. (Go to Settings, then go to 'About Tablet', at the bottom of the page):

http://s000.tinyupload.com/index.php...81702680450815

Just compare all those details should be the same.

And here is the link to my modified boot.img:

http://s000.tinyupload.com/index.php...80268258455189

You are comfortable with doing the rest by yourself? The guide explains it all pretty well, let me know if you have any problems and I will try to help.
[Android General] brainvision:
Thanks for sharing your files Shawn..

Anyway I'll repeat what I said already in OP: if firmware versions don't match don't flash, but try to follow the modding guide. At least be sure to have a full backup of partitions or official firmware [emoji880]
[Android General] comfortable:

Thanks for your help but the links are coming up as Not Found. I believe my build is later than yours (mentioned earlier in the thread). I'm pretty sure mine is 1.3. I'll have to check again when I get home.

brainvision

What tool do you use for a full backup on an unrooted tablet? I might as well do that before attempting anything.
[Android General] shaun_prawn:
New links for I15-TG modified boot.img

Ah sorry, those links did not last long at all, I have uploaded to google drive now.

Here is my tablet details:

https://drive.google.com/file/d/0B9rmfzmrSRNTc1RSa1Q0MkRjcE0/view?usp=drivesdk

And this is my modified boot.img:

https://drive.google.com/file/d/0B9rmfzmrSRNTb2lNb0JISER5Y2s/view?usp=drivesdk

Just in case anyone else reads this, please make sure you have the same kernel and build number as shown in my screenshot before flashing my boot.img
[Android General] brainvision:
Every kind of software that lets you clone and restore partition, it's plenty.. Also you should take a look at the iWork10 section of the techtablets.com, in particular the sticky threads and the Big Thread of How-to, from where I take info too [emoji123]

EDIT naturally if you just want to root and nothing more you can use Linux dd command for boot and recovery
[Android General] Lady Adellandra:
Stuck at Step 10

Model: i15-TD

Greetings~

Great walkthrough on how to root and recovery of the Cube iWork 10. I'm having the following problem: I received a new Cube iWork 10 today and found I can't get into the Android side. The previous owner's name is still there, and it's nine-dot pattern protected.

First off, I did all the steps until then correctly, and that gave me hope. I checked Device Manager and it first reads ADB Interface. (When at nine-dot Pattern)

I ran Minimal ADB and Fastboot, followed directions, and was unable to run the .img files.

It always told me < waiting for any device >, freezing there with a cursor.

I'm thinking it lost communication between the PC and the iWork when it rebooted.

Please help me!

--Lady Adellandra
[Android General] brainvision:
hi there, in the case you still have the issue.. you bought the tablet as used, didn't you? SO maybe the easy thing to do is to ask the the previous owner to tell you the pattern so you could reset the device.

Anyway before launching any command to flash img file did you check if the device is recognized by the PC with adb devices command?
[Android General] Bl4ckKat:
I also have a i15-TG. My kernel version is the same as the one posted on the last page, but my build is different, it's i15-TG_V1.2_20170808. Can anyone please help me out with a modified boot.img? Or would the one on the last page work for me despite the build version being older? ON the back of my device it actually says it's a i15-TC.
[Android General] darthcas:
Do the files in the post for resizing partitions work with i15-TD?

Hi!

Thank you very much for your instructions which are very clear and well written.

Right now I'm forced to resize the partitions as like for many people, the microsd slot stopped working no matter what I tried and the Android data partition is getting full even though I have deleted and uninstalled all I can, deleted all my content files and keep deleting files many times a day.

But I have some questions as my version of this tablet is the i15-TD which I already unlocked and rooted a good while ago (so I have the correct boot and recovery img files for my device). I'll enumerate these questions through my post so they are easier to notice and answer.

1- Does these files you mentioned are compatible with my version of the tablet and can I follow your instructions assuming they are?

* Cube iWork10 (i15-TC) 26052016.rar file from: https://drive.google.com/file/d/0B55gm49vxGYHWWpGaEFOMXB4dFE

* img files partitions from: http://rpeter.dyndns.info/xda

* gpt_....bin files from mediafire

* Windows drivers from here: https://mega.nz/#F!0AVVCJiL!z2NN8hIZEJPQBTngxgVkuw

* other files from here: https://onedrive.live.com/?authkey=!AEt5uW0vShObNiM&id=349D98B3AE35F242!112&cid=349D98B3AE35F242

* ... any other files I could have missed

2- If not can you clarify, point directions or provide the appropriate links for my version of the tablet?

Also before I start I would like to take the opportunity to install a more recent version of Windows-10 using a recent iso (for example copying the content of a FALL-2017 iso to the USB-stick) instead of the one that the tablet has installed, and in this way try to keep as much free space on the Windows partition.

3- Is this possible? Or do I really need to use the "Cube iWork10 (i15-TC) 26052016.rar" for this? --actually can I actually use this one? (as it says i15-TC)

Thanks and hopefully you can provide answers before I start.
[Android General] Bl4ckKat:
I have the same questions, but I have an i15-TG. Can you please tell me how you unlocked and rooted your device? Where did you find the boot and recovery img files for your device? I have made several posts here but no one will answer me, not even an admin. Do I need to find someone with a rooted and unlocked TG version and get the img files from them. Or is there some way you managed to get those files off your device before you rooted? If so can you please please tell me how you got them? I am on the verge of sending my device back because it's useless unless I root the thing or manage to resize android partition. Is there any links you have to show me hoe to dump the img files from your device?

I have tried so far macrium reflect which creates img files but will not allow me to get into the partitions. I have tried mini partition wizard and eausus recovery to try and get the image files via virtually mounting the boot and recovery partitions. Russion forums, chinese forums, and countless google and xda searches. No where can I find how people are getting these image files from there device. Maybe I'm just not understanding the instructions, do you need the boot and recovery files to root your device, or can you somehow get this files during the root process? Please help sorry for all the questions.
[Android General] darthcas:
Hi!

I unlocked and rooted the tablet more than a year ago following almost to the letter the procedure explained at the 1st post of this topic: https://xdaforums.com/android/general/cube-iwork-10-flagship-dual-boot-i15td-t3367954

But since that was so long ago is most likely that not all files at the end of that post will be useful to you particularly the boot image as it has to be for the exact version, build and kernel of your model of the tablet and you could brick your tablet if you use another one --don't use the Modified boot image (i15-TD) or Modified boot image (i15-TCL) img files in that post).

The rest of the file I think are fine although the SuperSu might be old and the TWRP i suppose should be work fine too --although I´m no android expert and rooting procedures I have only done to other 2 tablets in my life and only if/when it was definitely needed.

About your final questions, yes you need ALL the files BEFORE starting the procedure: drivers for your OS and adb/fastboot which you have to install correctly and test before the procedure, (proper) boot image for your version of the tablet, recovery image, supersu, all sha/md5 verified and which preferably should be on the same folder at a you hard disk, before you start typing at the CMD line preferably go to where those files are located, etc.

Since this is the 1st time I know about the i15-TG version I don't know where or how you can get the proper files for it but you can also search at the TechTablets.com forums.

I hope both you and I find the remaining files and answers to our questions :fingers-crossed: and maybe what I wrote have been somehow helpful to you.

Good luck :good:
[Android General] Bl4ckKat:
Thank you for replying Darthcas! That's what I thought can't use the files here. I got my tablet in October, the firmware has a date of September 8th 2017. Banggood don't or can't supply the rom. I did find a TG rom from a Russian forum along with the twrp and supersu. But the actual boot and recovery I cannot find anywhere. A few of us have this tablet now I find references to the model but no one seems to have the files!

I have heard mention that if you have the correct ROM you can somehow dump the needed boot and recovery images. I even know how to modify them for the root to work, I just cannot for the life of me work out how I can dump these files from the found rom or the stock my tablet is currently using. If I can find these files I can do the rest no problem with the instructions here. You would think in the coming months someone with my model will upload the recovery and boot img's somewhere online. Thanks again!
