Excellent!!!!

To make a factory reset of x98 teclast, download quick reboot app on 1mobile

1. open quick reboot

2. press recovery

3.press wipe data/ factory reset

4.Enter into the sub-menu. There you will find another option “Yes — delete all user data”

Select it and your tablet will get hard reset. :good:
[Teclast X98 Air 3G] Estiui:
No, I haven't, but I'm gonna try the previous solution, as the partition of the card was not originally NFTS.

how do I get dual boot menu back

my brother clicked the top to disable it and I would like to get the menu back
[Teclast X98 Air 3G] vpx:
If I know, what do you want, you can start tablet from power off - push Vol+ and Power few seconds, menu will be back, if not, power off tablet, repeat procedure and click on touchpad after start.

thanks that worked like a charm. Lifesaver

8) Turn off the tablet holding the POWER button for 10 seconds.

- Run Intel Manufacturing Tool as administrator.

- On the tablet, hold the VOL +, VOL- and POWER until you see the "Entering DnX mode. Waiting for fastboot command..."

hi,

I cannot make my tablet to enter the DNX mode. what am i missing?
[Teclast X98 Air 3G] vpx:
Make sure, that your tablet is completely OFF, it takes usually more then 10s. Then push Vol- Vol + and Power together, still push buttons and do not release them, until dnx mode appears, then you can release buttons.
[Teclast X98 Air 3G] sunshine76:

[Teclast X98 Air 3G] mnitstanley:
Whoah !! C9J8 !!! Thanks for confirming that rooting method works on Dual Boot models too !

What is the Build No. of your Android ? Is it 20141216 ? Did you check if OTA update is available for C9J8 ?

Check this post and compare

Mine is C9J7 and after OTA update my build no./date is 20141225.

[Teclast X98 Air 3G] cyanide911:
I'm seriously considering getting this tablet, looks *great* for the price. I do havea couple of questions:

1. The Dual Boot here: http://www.aliexpress.com/store/pro...blet-PC-1-83GHz-Retina/609719_1862203196.html is $229. Any chance of getting it for lesser?

2. Is the Keyboard worth it?

3. I'm surprised FIFA14 actually runs smoothly on this! I'm a very casual gamer (FIFA only) so you think this stands up to FIFA15?

4. Most importantly, International shipping from AliExpress - Should I expect insane import duty? Even if it's marked as a gift? (Country is India by the way).

Thanks a lot!

X10HD 3G just shipped today from Hong Kong, I'll be comparing it to the X98 Air 3G and see if it's worth the extra $$ over the Air 3G.

Is the 2560 x 1600 10'1" 16:10 screen, keyboard dock and 64GB storage worth it? I have my doubts it is ...
[Teclast X98 Air 3G] dimex:
are you constantly in contact with the manufacturers? I've seen your youtube reviews, but dont know if you're just doing it for fun.

Teclast should add an active digitizer model. After using a SP2 and now a Vivotab Note 8, I refuse to not have a pennable display since it's how I take notes at university.

It's the only thing holding me back.
[Teclast X98 Air 3G] zooster:
Keep us informed. Key points are: 1) possible performances slowdowns due to extra pixel count over x98; 2) battery life - smaller battery over x98 (8000 vs 8500mah), despite bigger and densier screen, is questionable; 3) quality of screen and digitizer.

This tab looks promising but on that device I would have embedded a more powerful cpu (z3795?) + 4gb dual channel + bigger battery (around 10.000mah). If coupled to lollipop it would have been the perfect tab. [emoji16]

Play Store Official Fix

The latest firmware (4.4.4 for HG5N) together with the update using the OTA works fine - everything works as it should.

In getting to this point over the past three weeks or so, I encountered some strange things whether software or hardware:

a) I had trouble downloading the three files needed for the Play Store fix. Each location I tried, my PC identified the files as Malware. So, I was reluctant to take a chance on trashing my PC.

b) My Teclast supplier provided me with newe firmware to resolve my issue with Play Store and a great step-by-step video to guide me through the process.

c) My tablet was an HG5N before the flashing and turned into an HG6M after the flashing. As well, the cameras were inverted. My supplier said that in was impossible to have inverted cameras on an Android unit, this only happened on Windows units....wrong!!!

d) I decided to try install the original firmware for the HG5N. Not only did that camera function return, but when I checked the OTA icon, there was an update to install and correct the Play Store issue.

Now everything works amazingly well. After rooting the unit and removing all of the bloatware, I am now thoroughly impressed by the function of this tablet. It is everything that I expected it to be in the first place.

I also own a Teclast P88 and I've never had any issues with that unit (other than replacing the battery).

Thanks to the many contributors of this forum, I appreciate all of the help and guidance offered.
[Teclast X98 Air 3G] zooster:
Guys what do you think is the best version of this device, c6j, c8j or c9j?
[Teclast X98 Air 3G] agunghost:
In my opinion, I will be more happy if Teclast releases the same factor/size of X98 Air 3G but with Bigger RAM and Storage (at least 4Gb RAM and 128 Storage) with keyboard like surface pro. I have surface pro (first Gen) with 16:9 display which is not pleasing (because of its' height).

And it's seem I agree with Mike Cane's preference of 4:3, instead of 16:10 or 16:9 display.
[Teclast X98 Air 3G] jasaero:
64gb should be a minimum for dual boot tabs. I do really want a nice keyboard and trackpad setup for stuff like these. Something more like the asus transformer would be preferred really though. Will be interested in how the size of this 10.1 compares though.

Hi Grayie & summerbreeze

I agree with summerbreeze that there is something wrong with many tablets and it should be replaced. But given the disappointment of returning everything (plus cost, plus time) isn't worthwhile to try to disable the turbo in the bios, as this workaround seemed to help summerbreeze to some extent, right? The boys will not notice probably.
[Teclast X98 Air 3G] SUMMERBREEZE:
Y

Thats true. To disable intel turbo mode almost sort the problem about freezing during gaming. Gpu is not effected as performance, only cpu is. It works max at 1.33 ghz.

Here is the settings

http://xdaforums.com/showpost.php?p=57717907&postcount=3655
[Teclast X98 Air 3G] zooster:
Do freezes affect both Windows and Android games? And isn't it possible to disable turbo mode from within the os?
[Teclast X98 Air 3G] ImJamIN:
I don't understand because you want to disable turbo mode in bios.

On android there are various apps that can help to configure max freq for CPU. For example with kernel tweaker (free at Google play) you can set max freq to 1.8ghz or more or less (you choose what you think it's the best for your use) and so the performances are almost the same with 2.15ghz. But above all, when you are not playing games you can immediately change freq to the max and so you have the best performance with other apps.

Give it a try;)

[MENTION=2198172]mirek190[/MENTION]

Isn't much better download the full Base from teclast?
[Teclast X98 Air 3G] SUMMERBREEZE:
they dont work at all, games still freeze. I and a few of others tried them (check the previous posts about this) and games still freezed. This is not just a cpu speed issue. This is mostly a voltage issue and i think when the turbo mode is on, it can not handle it at all. But when you turn it on, voltage is always stable and also cpu.. the apps you mention just change the cpu speed but it doesnt help the freezing issue at all.

for example :
[Teclast X98 Air 3G] deff_rolton:
Hello, Frontier, hello all guys! First of all, Happy new year and sorry for my poor English.

I have some issue with my Teclast 98. I did everything like Frontier said about Google play fixing, and my tablet started work perfectly - Google Play finally started to work!

But accidentally, I guess, I deleted something important for Android to start up and reboot. Yesterday battery fully depleted and Teclast deny any loading anymore, I even can't reset to factory setting=( It shows "Intel inside" logo and nothing going on =(

Thank you in advance!

[Teclast X98 Air 3G] Frontier:
Hi Mike, happy new year (and rest of you guys here),

The only thing you can do is reset your tablet to factory defaults.

To do this, enter the droidboot recovery mode by shutting down the tablet and then hold vol+ (or vol-) and power. On the droidboot menu, select erase data / factory reset (using vol+ / vol- keys) and power to execute selected command.
[Teclast X98 Air 3G] SUMMERBREEZE:
Please from droidboot, do a factory reset, if it doesnt work, please flash the original ROM from Teclast website by using Intel Manufacturing Tools (please check the android development, page #1)
[Teclast X98 Air 3G] mirek190:
Stock bases from teclast are updated to newest fixes from 25.12.2014 ?

If someone update them then could could make copy via ADB dd command and put them on mega.... but if not ....not problem I update roms later...because I have to download stocks - update it - clean - add mods...

Btw.

I think to remove that 3 dots no navigation bar ...or not - what you think about it ?
[Teclast X98 Air 3G] SUMMERBREEZE:
The tablet is under discount (%10 off) 269 USD plus 2 USD store coupon = 267 USD and also if you talk with the seller and press a bit, they will agree to ship it via Netherlands Post (arrives in 9-10 days)

It seems a good deal.

Haven't really looked into it, but are the Baytrail freqs/volts editable within the BIOS? Who's to say you can't just watch your temps and throw a little more voltage at the chip? Might solve your freezing issues.

Yes I have been told by OKQI, but they couldn't tell me if they have the hynix or anything but the slow BIWIN eMMC flash drivers. My 120mb/s read and 40mb/s write Biwin eMMC is super painfully slow!

I'm uploading an unboxing and quick hands on video to my channel now of the vi8. The Chuwi Vi8 is surprising good for $99, same spec as the $249 Dell Venue 8 Pro. My Vi8 has a 160mb/s read and 80mbs write eMMC hynix module, much faster than my Air X98 Air 3G's :(

Yes, in the Bios. You can look under devices or one of the screens there and it lists the eMMC details (brand).

Sure: https://www.youtube.com/user/hendrickson Unboxing video will be up in 10 minutes more to follow.

So it was working and then suddenly stopped? You have tried the obvious things like power it off completely and reboot it. Sounds like it could be a hardware issue.
