I'm comfortable doing Android ADB stuff from a Windows desktop machine, as a long-time Android owner I've flashed many a device that way. And recovered a few bricks too...

I assume you're asking, so from the notes I made to myself last night (I always make notes about this kind of thing else I'll forget when I get a new one or have to re-install)

To disable connected standby - however I now leave it on but enable hibernate (see below)

For those looking to disable Connected Standby on Clovertrail (and similar) Devices: A simple change of a registry key and a system restart exposes all the legacy functionality: HKLM\System\CurrentControlSet\Control\Power\CsEnabled (1->0)

To enable hibernate

Windows admin command prompt: powercfg hibernate on

to hibernate, type this: shutdown /h

To make a shortcut: create this desktop shortcut: "C:\Windows\System32\shutdown.exe /h"

I assume they don't enable hibernate because of fears it'll trash the eMMC/SSD rapidly. I more fear that the battery will be worn out first through constant charging...

And actually, that makes me remember, in some ways the best thing about the Xoom was it was only a few months old but was being sold off cheaply - and so were all the accessories. Official cases, car chargers, all dirt cheap.

And that's one great thing with this X98. Because it's essentially iPad Air size, lots of old Air accessories fit it. The screen protector is £1 from Poundland; a decent case was £7 from PC World (could have got one for £2). Actually anyone wanting a decent bluetooth mouse, unbelievably (UK) PC World's own-brand BT mouse (which is two-mode also does its own wireless connection with a dongle) is only a tenner at the moment and it's surprisingly good. Just want to find a good, but cheapish, BT keyboard now. I really am sad. :p
[Teclast X98 Air 3G] SkOrPn:
Yeah hibernate may not be good for the emmc. However, if there is enough space for it, its a good option if you need the device to save battery. I'd prefer these devices to have faster boot really. I wish we had 5 second bootup times already, lol as I wouldn't even care then and can turn off the device when ever I'm not using it.

Still dunno how to flash, I just stuck at erasing cache. Timed out.
[Teclast X98 Air 3G] Petepe10:
Ok with me, but I prefer you do not put a browser in the system app folder but in the normal app folder. Problem with system apps is that it they are retained forever, after an update you have 2 copies, And they can not be deleted if you want another one, wasting space. (Well, they can be with linksd etc, I know, but not in the normal way).
[Teclast X98 Air 3G] mirek190:
Ok I leave stock browser in 4.4 .

What you say about stock browser in lilipop ? Because I used chrome instead of that stock browser .

Stock browser from 5.0 is ....hmm very strange for me.
[Teclast X98 Air 3G] oam_xda:
This is also my question. If and when I get the CH341A eeprom flasher, I need to get my Windows key injected to the new BIOS. I only have it on text file which isnt directly usable with taipower utility.
[Teclast X98 Air 3G] Perfectdevil:
Firefox for god sake
[Teclast X98 Air 3G] royeiror:
I'm partial to Chrome, but the Stock AOSP browser could be a good compromise for the people who prefer FF or Dolphin or any other.

For me the stock browser is just like IE, a means to get the browser I want.
[Teclast X98 Air 3G] SkOrPn:
No browser please, except for the one already provided in the ROM by default. If one wants Chrome, FF, Dolphin or Lightning it can be downloaded from the Play Store. Otherwise you will need to include all of them to be fair... lol
[Teclast X98 Air 3G] mirek190:
Ok I see - in that case in 4.4 and later in 5.0 will be only asop browser.
[Teclast X98 Air 3G] astromark:
I think the stock browser is excellent - personally I'd say keep it and let users install Chrome or Firefox or whatever they wish in addition.
[Teclast X98 Air 3G] whymoo:

Hardware mod?

Wow, what a difference BIOS 2.02 makes - yesterday I was at about 20% after 8 hours with very little use. Today after flashing and with a similar use I'm at 80%.

Anyway here's a question for someone much smarter than me with hardware.

I'd really like some clever soul to work out how we can physically install a wireless keyboard USB dongle inside the case. Obviously we'd strip the casing off the USB dongle to make it smaller - looking at the photos there might just about be room: http://techtablets.com/2015/03/teclast-x98-air-ii-photos-of-the-internal-components/

But is there anywhere and any way it can be soldered to a port or UART or whatever? I've seen similar things done to Android devices before now (with people retro-fitting GPS chips inside devices, I think - I've been trying to find the XDA thread from a couple of years ago.)

There are loads of decent wireless keyboard/trackpads out there, far more so than Bluetooth ones - and anyway I'm getting quite bad wifi/BT interference at times too. This would be a neat solution.
[Teclast X98 Air 3G] royeiror:
Wouldn't this take over the USB port? Maybe there would need to be the components of a hub in order to keep the port and have the dongle inside the case.
[Teclast X98 Air 3G] astromark:
Not sure, you'd have thought so. I left hardware behind a very long time ago. Here's one of the threads I was thinking of - someone trying to add GPS to an ereader! Gotta love XDA. Someone was doing something clever with the pinouts of a UART.

There are photos. http://xdaforums.com/showthread.php?t=2294079

hg9m overheat, shutdown while charging

Hey has anyone fixed the hg9m or other variants from overheating or shutting down while charging and playing games? It seems very much like some type of bug or perhaps something to do with how windows changes power handling when plugged in as even very low current chargers like my 500ma battery pack still cause a shutdown. I did open it and added a sheet of metal some electrical tape and thermal paste on top of the soc so it transfers heat to back case better but didn't seem to do much except make the back get hotter, which means its transferring more heat but not enough I guess. Any one else have a software\firmware solution? Thank you :)

[Teclast X98 Air 3G] SkOrPn:
Find me some really high quality pics (I mean VERY high quality close ups) of the 3G GPS module/pcb area, and or a dead/broken Teclast and I can try to reverse engineer it for you. I have been modding stuff like that for nearly 30 years for Intel, Qualcomm and Lockheed Martin. If the 3G module is USB based, then one can assume the non 3G teclast has unused solder pads. To save money on PCB design these devices may not have traces for extra USB ports in its specs. For example when I added 128GB to the internals of my Dell Venue 8 Pro, there was 8 unused solder pads on the PCB (two full USB ports just sitting there to be tapped into), so I not only installed a 128gb USB drive inside the unit next to the battery I also installed a full sized USB port. Not all devices will have such solder pads just sitting there for you. I recently asked Chris of TechTablets if there were any of these free USB pads in the Teclast but he didn't know, so I would have to spend time with the 3G/GPS model and a little research to see how the chip gets its connection. Definitely looks like there is room for adding stuff, but again I do not have the device yet so I do not know for sure. If its using USB for everything, such as 3G, GPS and WIFI etc, then it would be really easy for me to install a small logitech universal receiver somewhere inside (should be anyway). By the way, your interference that you mention maybe caused by USB 3.0 hubs, so stay at least 3 feet away from them when your using a 2.4ghz wireless receiver. My logitech receivers only work if I place my USB 3.0 hubs on the opposite side of the desk, lol. Any closer to the HUB and my mouse dies or gets erratic.

I plan on buying the Teclast x98 3G next week, but I am not much interested in adding storage space or possibly risking harm to my device. I "might" be reverse engineering it so I know what is what on the PCB, but I'm not sure yet I even care :) That really depends on how bored I get some day and if I find a need to do it, like we did with the Dell (turned it into a Porshe Car Dash Radio for my little brother). lol

Hi :)

got now my second Teclast x98 (C5J5 - 32GB) and installed "android 5.0 mirek190_v2.0" (Thank you mirek190 for your work).

Everything seems to run as expected. Only Instagram keeps crashing with an whitescreen or it dosen't even start.

I tried to install Android 4.4 but I couldn't find any compatible rom for the C5J5. I also tried to install an older version of instagram (same result)...

Does anybody know how to fix this issues or does anybody know an working 4.4 rom for the C5J5 (other than remixOS)?

regards

Sep_michi
[Teclast X98 Air 3G] astromark:
That's the spirit! Exactly what I was hoping for! :)

I have the 3G model so there might be less option. I'm not planning on taking the back off (yet) but if anybody else has had to in order to remove the BIOS chip, would you be kind enough to take some hi-res photos of the board?

The Logitech adapter is exactly what I'd like to fit to work with their K400r keyboard/trackpad combo.

I don't have a USB 3 hub so it won't be that interfering. I just notice that wifi and BT trip each other up on some of my devices. In this case it causes the mouse to stutter, for instance. Turning wifi off on the tablet cures it.

Also it means that the mini USB port is free for charging; I know there are splitters but even they seem hit-and-miss for simultaneous charging and OTG use.

I do have a mini keyboard/trackpad combo I bought from Gearbest.com that I plug through OTG for any need that arises, but frankly I don't think Windows 8 is a polished tablet experience. Android is amazing so no need for a mouse, and the iPad 2 I left behind for the teclast was way too slow for anything but Netflix or Kodi.

I do hope Windows 10 will make me want to jump from Windows 7 immediately.

Ok. BIOS 2.02 works on C9J8 too. Flashed with fptw-tool under Win very comfortable. Restart after long-pressing power button works well - No brick! The price to pay: No front cam anymore. Bios seems to show OV2680 instead of GC cam in both OS, Android & Win.

Battery drain is now down to 9%/7h, means about 1,3%/h.

Edit: After de-activating the non-working front-cam in device manager, the drain got reduced to 0,4%/h.

about to give up on fixing battery drain in windows via BIOS flashing.

I have a c5j6 model,didnt come with UpdateIFWI so I installed the apk from someone having same model than me here on the forum,tried the falsh the bin file and it runs forever doing nothing

yesterday night,tried mirek method but after loading to the screen where you chose between system flashing or bios flashing,I use option2 and nothing anything happens,with a prompt flashing in the cmd windows.

I followed strickly the step by step below,frankly doesnt know what I am doing wrong.

any other file than the bat file should be at the root of C: disk or something?

or the adb version I am using is not the required one? has someone a link to the correct one you ahve been using successfully?

my tablet is perfectly showing on my windows PC while plugged in so I "assume" nothing wrong here but only god knows:rolleyes:

help:confused:

On PC - installed adb .

- unpack flasher on drive c:\

- go to task menager and check that adb is killed .

- run flash.bat ( not as administrator )

- plug tablet via usb

- run flashing ( read everything what appears ) it takes around 2 minutes

- it should end with - finished or so

- wait 1 min and keep power button until swith off tablet itself .

Random Hibernation issue

Try checking the event manager and see what causes this random hibernation.

Also do you see the thermal event throttle message on android? I get this message and in windows it happens because of heating according to the event manager.

I added a copper plate and thermal paste between the soc and the metal shield now the temperatures are very low compared to before even with charging (at a very low capacity which was a major problem before) it doesn't hibernate except for when i am on gorillavid streaming. on android i don't get the thermal throttle message anymore.

I will add a thermal pad (1.5mm) between the aluminum cover and the shield and see if the problem is solved or not. Unfortunately 1.5mm pushes the screen so if it works i will order a thinner pad.

let me know a few things, i may be able to help you fix it.:

1. the temperature range you see

2. the event around the time of hibernation

3. how the cooling solution on your soc is installed.
[Teclast X98 Air 3G] SkOrPn:
Cut a hole in the back cover and install a real copper heat sink, that will fix it.... lmao j/k

[Teclast X98 Air 3G] Okluzhion:
Can somebody explain how to flash Remix OS? I can vaguely understand the process, but the English is too broken for me to understand the instructions completely. If flashing for the first time (I have Android-only Air II), I need to install universal adb drivers, isoc and Intel android driver exes, and Intel manufacturing tools. In the OP, the poster says the tablet needs to be plugged into the usb while installing isoc, but the installer itself says that all the intel devices should be unplugged. That's the first confusing thing.

I understand that I need to (when everything installs correctly) open Intel mnf tools, then from there open the ROM folder and select, in my case, flash.xml. After that, power the tablet off, hold vol up, down and power button to enter Teclast DnX mode, connect it to USB port and flashing should start by itself, is that right? Now, on the chinese forum, it mentions some Bios thing, and 5.0. Now that's the part I don't understand at all.

I would appreciate if anyone could help me out!
