    Hi, I expect next week to recieve my x98 pro.

    I have read all forum and I want to make a “FAQ” for me nd for anyone in my situation.

     

    • Accessories

    usb otg chargerhttp://techtablets.com/forum/topic/x98-pro-otg-charger/

    recomended usb otg charger in banggoodhttp://www.banggood.com/4-Port-Micro-USB-OTG-Charger-HUB-Cable-For-Tablet-Phone-p-975460.html

    keyboards / case: you can use all of ipad air 2 (as they are the same physical size

    Problems with chargers: plug the USB cable in the tablet and the charger BEFORE plugging the charger in the wall

    Power tips:  I don’t know if it’s my unit that behaves in a really weird way, but if someone experiences the same difficulties, I have been performing tests with 6 different chargers, 7 different USB cables and an amperimeter….

    The circuit controlling the battery of this device does not behave on the expected way. It seems to have two modes:

    • 4.44 V on the USB port: Windows detects this as “running on battery”, and the tablet does not charge with any charger
    • 5.1 V on the USB port: Windows detects this as “plugged-in” and the tablet charges

    The amount of current it takes is pretty random, when the battery is low I’ve seen it draw 1.8 A, when it is almost full it lowers to 1.35A

    But sometimes it enters a state where it only draws 0.45A. To get the tablet out of this my trick is to plug it a charger that is not connected to the wall, that must discharge some capacitor or something like that, and then the tablet goes back to fast charging mode.

    Be aware that this thing eats so much power that with the screen at 100% brightness and a 3D game the charger will not be able to keep the battery charged.

    Long cables (2 meter) can be used if they are made with AWG22 / AWG20 / AWG18 copper wires, charging current is exactly the same as when using the official (and very short) white cable.

    If the tablet doesn’t power on, plug it into a charger and press power button for two seconds. 10 seconds later you should see the Teclast logo and an animation showing the battery level. At least now we know the tablet works and has battery charge.

    Unplug and press power button, hold the tablet close to your ear. If you hear a high-pitched noise the battery is in one of those “I refuse to work as expected” states. Keep pressing the power button, the noise will change the frequency. After a minute it will stop and the tablet will boot.

     

    • Thermal Mod and full size USB mod

    http://techtablets.com/forum/topic/x98-pro-battery-life-thermal-mod-usb-mod/#post-16936

    Copper pad for the CPU:  I used a 1 mm thick copper one above CPU and RAM chips.  (15×15 mm on the CPU, and 7×15 mm above each pair of RAM chips)- I used Artic silver / MX4 thermal paste to be sure that it will make good contact.

    Then, I added a 50 x 50 x 0.5 mm silicone thermal pad between the EMI shield and the back of the tablet.

    1 mm thick may be too much, it will make the tablet motherboard press against the back of the screen.

    To open the tablet start by the top, where the white plastic band is. I used a knife to open a little and the with just a finger nail, slowly unlocking the plastic tabs all around. The corners are difficult, there are plastic tools to do this kind of job, try to find some hard plastic thing like a credit card.

    When putting back the back cover, start with the tablet in horizontal position, with the buttons down, put the buttons in the holes in the back cover and then fit the corresponding edge of the tablet. Continue closing the back, pressing around until all plastic latches click in place.

    Full size USB modhttp://techtablets.com/forum/topic/add-a-full-size-usb-port-on-x98-pro/

     

    • Bios

    bios update: only if you have problems with emmc: http://techtablets.com/wpfb-file/x98-pro-k9c6-bios-1-13-emmc-fix-rar/  http://techtablets.com/2015/10/teclast-x98-pro-boot-to-bios-missing-emmc-fix-bios-update/

    bios update (spanish translation og techtablets link): http://www.htcmania.com/showpost.php?p=20718293&postcount=113

    Becarefull, use capitals. The command line arguments aren’t all in lower case.

    Enter bios: power it down and connect a wired keyboard to it using the supplied usb HOST cable. power it up and keep pressing F7 until you get into the bios. Now go through the bios with arrows up/down. Also ESC or SUPR.

    Stability: In BIOS select the IGD Turbo mode, set it to DISABLED

    Force to open OS selection menu: turn off, and try to boot with Volume up button and power buttons pressed together

    BIOS version:  enter the BIOS, look for Project Version

    K9C6 1.05 Version: http://techtablets.com/forum/topic/older-k9c6-bios/

     

    • Windows 10

    The tablet comes with a Windows 10 license on the BIOS, it activates with no problem. Yo don’t need a special Windows version from Teclast. I’m using Windows 10  November 2015 edition downloaded from Microsoft and it’s activated.

    tweak power options in windows 10 to reduce stress in CPUhttp://www.eightforums.com/tutorials/51027-power-options-add-remove-min-max-processor-state.html

    Install Windows only. Create a Windows 10 install pen-drive with the Microsoft Media creation tool or Rufus tool, connect a USB hub, connect a USB keyboard, USB mouse and the pen-drive. Boot, press F7 to get boot menu, chose to boot from the pen-drive. Launch Windows install, during the install process delete all partitions and install Windows normally. You’ll end up with a 58 GB partition with Windows taking about 11 GB and the rest free.

    May be you have to set the label of USB to “winpe”, GPT partition and NTFS file system

    From another user: First thing I did was re-install Windows 10, which went completely smooth. I backed up all the drivers with DoubleDriver, then booted off a Windows 10 installer flash drive, deleted all existing partitions (including Android) and did a clean install of Windows 10. I actually was going to install Windows 10 Pro, but it turns out the installer picked up the embedded Windows 10 Home product key from the BIOS so once the install was done I noticed it was Windows 10 Home. Either way, once I booted back in to Windows it was fully activated. So it’s nice to know there is indeed a valid Windows key on the device, I thought I may need to buy one based on some other reviews. Re-installed the drivers from my DoubleDriver backups and I was good to go. Sidenote, I don’t have a charging OTG hub yet so I did the re-install on battery power… which seems like it’s probably not the smartest idea, but the tablet made it through fine with plenty of battery to spare.

    • Android:

    DNX BOOT MODE: Entered by holding down volume and power buttons

    FASTBOOT mode: Entered from dual boot menu  (OS selection menu), select android & hit OK. .. then press volume down & up buttons together until you see the FASTBOOT screen

    Android Safe mode: Entered by touching and holding the power off option from the shut down menu and a new window will pop up asking if you want to boot into safe mode

    ROOThttp://techtablets.com/forum/topic/x98-prok9c6-rooting/

    ROOT NEW METHOD: try this and tell us (read all post, it is not at the begining) http://techtablets.com/forum/topic/twrp-2-8-7-0-recovery-for-x98-pro/

    TWRP 2.8.7.0 recovery: http://techtablets.com/forum/topic/twrp-2-8-7-0-recovery-for-x98-pro/

     

    a. other “keys” tweaks. i dont know how to enter android recovery or fastboot.

    b. how to resize partitions so reduce android and make a windows’s one bigger

    c. how to backup a complete copy of your tablet just when you recieve it. (may be macrium reflect??? does somebody check it?)

    d. how to check your real windows version so you havent got a beta version of windows 10

     

    Please, tell me by private message in order to complete this post. Or if anyone have more questions, I will put in this list. If anyone answer me, i will delete question and put the answer above.

    It will be great also if Chris consider it to stick it.

    Thank you, Juan! Maybe disabling the IGD Turbo mode is actually teh solution to my stability problems … I sure hope so. So far the X98 Pro is completely useless for me, I’m afraid …

    BIOS version:  Press Esc  or Supr while booting to enter the BIOS, look for Project Version

    Key combos (copied from another post on this forum)

    If you hold down the volume up key together with the power button it will override this and boot up to the dual boot screen

    DNX BOOT MODE

    Entered by holding down volume down and power buttons…

    FASTBOOT mode

    Entered from dual boot menu… select android & hit OK. .. then press volume down & up buttons together until you see the FASTBOOT screen….

    Android Safe mode…

    Entered by touching and holding the power off option from the shut down menu and a new window will pop up asking if you want to boot into safe mode…

    One thing I will add, my X98 Pro was crap, and would crash all the time, and now again would get stuck in the bios bootloop, after running the fix (flashes a new bios) this device is like a complete different unit, barely any crashes or hangups atall, I would say, everyone should flash that fix, as it looks like it repairs curropted stock memory or something, Im not too sure, but, I was ready to put it on ebay until I run the fix..

    Just working on getting xposed working on it now..

    I can’t download the firmware after X98 pro root therefore my play store continues to crash. During the firmware download I get message “installation aborted” then I need to reboot then tablet works fine. Android without the play store is a drag! I uninstalled the play store and install new version and continues to crash! I am using the teclast pre installed app to download the firmware.

    Hi there! Thank you for this good compilation of topics. I do not know what to do with the camera. I have installed Windows Home fresh using the whole drive. My camera is working but only the front one. I have no option to switch to the rear one.

    I have installed the 64 bit driver listed here but it does not change.  Any ideas? Anyone with the same?
