Yeah I was thinking the Cube because of the problems I see with Onda. As well as the inside of the Onda dont seem well made according to this video.

https://www.youtube.com/watch?v=vspDY3mw7fw

The other problem is that cube has been caught lying about the resolution and CPU speed of their tablets

http://xdaforums.com/showpost.php?p=54193447&postcount=12

So Onda has not so good build quality, software heating issues, and they lie about their Antutu scores. Cube lies about specs and Antutu scores. And Teclast has issues with heating and several other things mentioned in this thread. It makes it very hard to choose between these companies. Im tempted to test them out to cure my affordable tech itch...but I dunno.

Damn...these tablets reach 75 C often when gaming? That seems bad compared to my experience with other tablets. Or am I incorrect about the normal temperature range for tablets under load. That just seems high to me. I worry about the chips burning out in these things. Ive read a few horror stories about certain Chinese tabs being opened after they failed, and finding burnt chips along with the electrical smell.

I don't think the Teclast gets that hot Hendrickson's was at 43 degrees after running the Antutu benchmark while the Onda was at 70 something.

I don't think it really has heating issues and I think it will last you the longest in the long run.

If there in no other choice I'll do it if someone will explain me how.

I don't have one at hand, but pretty sure the Teclast doesn't support digital/active styluses. Note 3/4 have screens that accept active digitizer input. Think there is an earlier post in this thread that also confirms this.

[Teclast X98 Air 3G] benbraun322:
Did you flash Mirek190's ROM with partitioning? Because I believe he decreased the cache to save disk space.

Your going to have to flash with partitioning and you will lose your data but if you want to increase the storage for the cache, that's what you have to do.

Flashing is much more simple then you think.

Do you have Single Boot android or Dual Boot?

[Teclast X98 Air 3G] benbraun322:
Well if you believe the problem is the cache you don't need to the official Teclast ROM if you don't want to, you can just reflash your favorite custom ROM for the tablet with an edited Partition Table.

You are going to have to wipe your Teclast and you will lose Windows and you'll have to reinstall it afterwards.

Please watch Hendrickson's YouTube video I believe it is linked in one of the first few posts.

It is very helpful, you can skip the first few steps because you already have the correct Dual Boot BIOS installed.

All I can say it's that bios 1.05 and more 1.07 have adjusted voltage because temp of CPU are more high than 1.03 bios with the same app or same use, but I haven't had any problem of GPU.

Microsd problem

Hello,

I have some problems whit external microsd.

I can write it only whit es file explorer and when I create a new folder there is always a file randomly named somethings like -1531019362.

I can't write external microsd whit any other app I tried.

I have android/windows dual boot, windows is not installed already but I have the bios already installed.

I use mirek190 rom v3.1 for c8j7 whit 8gb of storage.

Someone else had same problem?

Thanks in advance.

In last few posts there are queries about flashing only android on dual boot tablet without affecting Windows. Here I would like to share the steps:

1. Download Mirek190's ROM (or any other which you like) from the links given in OP on first page (Anyone will serve the purpose, but as far as possible choose one nearest to your model).

2. Extract the contents on PC. You will see a file named "system.img".

3. Connect the tablet to PC (Hopefully it is rooted already). Also ADB and Fastboot must be installed on PC.

4. Reboot the tablet in fastboot mode by passing command 'adb reboot bootloader'. Tablet will now boot into fastboot mode. If it turns off, press power button once and fastboot mode will start.

5. Now flash the system.img from Mirek190's extracted ROM. 'fastboot flash system "yourpath\system.img"'. Flashing of ROM will now start and you will see the progress bar on tablet screen.

6. When finished switch off the tablet, disconnect from PC and power on. It should now boot into new ROM without affecting other data.

I got different reaction at different toys. Samsung galaxy note reformatted it just after insertion, Cube talk x 9 found it was damaged ...

There were written that

Android 4.4 KitKat removes ability to write files to the MicroSD card (on phones/tablets that have both internal memory and user-installed MicroSD cards).

In case you can try this fix.

[MENTION=6524670]rudivb[/MENTION] yes...the same one. If you want to change partitions, follow flashing guide in Dual boot section in OP. You can modify partition.tbl file included in mirek's ROM as per your requirement. But probably you will need to replace image files except system.img with the files for c8j6. No idea where to find them. So be careful while using Intel Manufacturing Flash Tool.

[Teclast X98 Air 3G] jaycrewz:
So Ive decided to go with the Cube I6 for now. Im going to do a video review and start my own detailed review thread after Ive had it a little while.

I may still try the Teclast once I get my tax refund, but Im not sure yet. I chose the Cube because most things Ive read said the build quality was the best of the Chinese brands who make "retina" tablets in 4:3 aspect ratio. Also the Cube seemed to have less hardware issues out of the box, and a very stock version of Android without any Chinese bloat ware.

The only downside for me is that Cube only has a 32GB model, and it has that antiglare filter underneath the screen. This gives it that slighty "grainy" look mentioned in a few video reviews on Cube tablets Thus its not quite as bright or as sharp as the Teclast. Still looked great though in Hendrickson's videos.

Thanks for having such a great thread here everyone. Hopefully we get a sub-forum soon for these Chinese tablets.
