Installing Win 10 & modifying partition size

Hello,

I am a newbie at this, I have a dual boot x98 air 3G (C9J6). I want to change the partition table of my tablet to reduce the partition size of android and install the new [MENTION=2198172]mirek190[/MENTION] rom. And I want to install windows 10. Can someone tell me how should I upgrade it. i have seen the dualboot video by [MENTION=1167021]Hendrickson[/MENTION]

I can't find the compatible rom and bios etc. I would really appreciate if someone can help me out.

Look at my Tutorials in my signature, you will find a link to Firmware 2.05 which is Dual boot, in fact 2.02 work to with Dual boot, I have also a tutorial on resizing partitions with WinPE. :angel:
[Teclast X98 Air 3G] maxedout56:
Hi I already have dualboot on my tablet. I have attached the screenshot of my firmware in my tablet. What I want to do is basically extend my Windows Partition and make the android partition smaller (android similar to the ones in the 32 GB Tablet version). Is it possible to resize the partitions without reinstalling the firmware?

And compared to my version of the firmware what are the changes in the version 2.05?

I would also like to know is it possible for me to make a backup of the complete system drive of my tablet? like a norton ghost or something of the complete drive.
[Teclast X98 Air 3G] Mikha777:
The tutorial to resize/delete partitions work with PartitionGuru and it see all partitions so you can resize/delete any partitions on your X98 (be careful), to resize or delete partition you don't need to upgrade your firmware. :cowboy:

Since you have a X98 AIR 3G You will be better with 2.02 Firmware cause it support GPS, the advantages of 2.02 Firmware/bios over 1.05 (the one you have) is that in sleep mode it fix a battery drain under Windows, it's easy to do but like every Firmware update there is a slight risk of bricking the tablet, but even if bricking occur it's also ez to unbrick it with CH341a programmer. :o

If you intend using Windows more 2.02 Firmware would be a very nice upgrade to extend your battery life. :silly:

Hello!

I have Teclast Air III Dual boot. I flashed with mirek 7.0 firmware http://xdaforums.com/x98-air/development/mirek190romv5-0-android-lollipop-t3206772

with full repartition for android.

I have several questions:

1. Could I now enter to bios? In dual boot menu I have only Android icon, but not Windows icon like in this video

https://youtu.be/rLjayeQJg4Q?t=617

If yes, how to do this? Could I enter without USB keyboard?

2. Can I restore my windows key from BIOS after reinstalling the windows?

Thank you for your help!

Thank you for your help!

Sorry for my lack of knowledge.

1. It's a perfect virtual keyboard. My steps: 1. press power on/off button while shutting down 2. Press power on/off button 3. When the logo appears I touch the area as described, but nothing happened. Where is my mistake?

2. I don't have windows now. And I didn't save the key after full formatting with partition of disk and installing only Android. Or this program could read the key from BIOS?

Thank you once again.

Regards.
[Teclast X98 Air 3G] Mikha777:
For the keyboard you have to be

very quick

you have only 1-2 seconds to select it by default but once inside the fimware you add few second to help like 5 seconds ;) I've only tested it on my Teclast Air II and Also 3G so I'm not 100% sure on Air III but logically it should do the trick.

If you don't have Windows you will need to use/build My WinPE on an USB drive and boot from the DRIVE and put or download this utilities that is able to read from the BIOS/Firmware: https://neosmart.net/OemKey/ and for the WinPE: http://sharetext.net/Oub.html

But to boot from USB Drive you have to go in the Firmware... :eek: So the best thing you can do is buy a cheap USB hub (if you can afford buy a UB3 compatible hub) and a cheap used Keyboard or use one that you already have. This way you will be able to use Keyboard Mice & USB drive at the same time, very usefull. :cowboy:
[Teclast X98 Air 3G] wegosi:
1. Thank you. I just was clicking very often in the area of the ESC and then change Setup Prompt Timeout ans Saved.

2. I have youtube channel where I explain newbies how to install mirek roms for example. That is why I want to know, is it possible to install windows with hidden keyboard? Because I should tell all variants for users)

Regards.
[Teclast X98 Air 3G] Mikha777:
Yes you can use the "Hidden Keyboard" to install Windows you only need the keyboard to access the Firmware after the touch screen is enough for the installation. ;)

You must be a little bit lucky to have the keyboard the first time at least. :silly:

To all the kind & magic helpers!

I'd like to apologize if this issue has been presented and discussed already, however I couldn't find the particular solution after browsing for 2 hours in this thread.

My problem:

I'm using the C9J8. I successfully flashed from mirek v5 to v7 using his flash tool v3.

After booting up I decided to flash to the newest bios v2.05 - again using his flash tool v3.

It ended successfully - the message popped up and flashed to "KEEP POWER BUTTON FOR 10 SECONDS TO SWITCH OFF DEVICE OTHERWISE YOU BRICK YOUR DEVICE !!!",

which I did exactly. I held the Power Button for 10 seconds until it shut itself down.

However, now the tablet doesn't boot up again at all. It's just blank, black, no reaction. I tried every possible combination of buttons in the book trying them out connected to the power plug, connected to the computer and not connected, holding for 3 seconds, holding for 10 seconds, holding for 30 seconds. You get the point!

Does this mean the tablet is bricked (even after following all the steps correctly and receiving a successful message)?? Or is there another trick I might try?

If so, how do I proceed/unbrick it now. I saw that Mikha777 has a tutorial regarding unbricking in his signature (however it only seems to be for the "Air II"). And where can I buy such a programmer (maybe someone can send me a link in PM)?

I appreciate any help!!! :) I'm kind of lost right now..

Thanks for your reply!! Brilliant - just ordered. Will take a while to arrive but at least there's hope. I looked a little further into the tutorial and I understand now what to do!

Thank you for providing me with help :)

As for flashing the bios on a C9J8 to 2.05 I cannot recommend using Mirek's flash tool v3, since even though everything went well, the device bricked (flashing the rom and using the flash tool itself is super intuitive though - kudos to Mirek!!). I don't know if it's due to the model or the flashing procedure. First time around when I flashed to 2.02 I used TecKnight's solution, which went well overall.

I will keep you updated and report how it will go - in case anyone else runs into similar problems.

Cheers!
[Teclast X98 Air 3G] Mikha777:
No problem, look at the UEFI method in my tutorial to flash the firmware/bios it is not tie to any script and you only need the tablet (no other computer) to use it, you will have one more tool in your kit :angel:

It took 7 weeks for mine to arrive.. if you are lucky it can took 5-6 weeks but 8 weeks is the norm ;)

Have a nice week-end ! :cowboy:

Teclast x98 Air III / 3D Games freeze and low battery (fall quickly after 45%)

Hi,

I'm beginner in the world in chineses tablettes and sorry for my english, is not perfect

I just received my teclast x98 Air iii m5c5 but i have 2 problems, and i can't resolve it.

_ 3D Games crash after 30 seconds gaming ( screen freeze and forced to restart )

_ the battery down quickly from 45% up to the end of its autonomy ( and in test the battery capacity reveals 4890 mah but normally it's a 8500 mah capacity)

If anyone has a solution to this problem , you would save my life :good:

Thank you very much !

Hi all,

I'm following this thread and its good information for a while but still I don't find a solution for my problem with the Teclast X98 Air II.

I have given up on Windows after countless tries of changing partition sizes or doing a clean install.

My current plan is to install Android only using the mirek distribution, however:

- the tablet boots into the screen "DnX mode, waiting for fastboot command"

- the tablet is recognized by fastboot devices on my Mac (but not by adb devices if this matters)

- however all fastboot commands that I take from the mirek scripts faill, except for

fastboot osloader ROM/efilinux-userdebug.efi

if I try

fastboot boot ROM/droidboot.img

I get:

downloading 'boot.img'...

ERROR: usb_read failed with status e00002ed

FAILED (status read failed (No such file or directory))

finished. total time: 294.659s

Same failure for all other commands, including the partioning commands

Can somebody help me?

Thanks in advance!

If someone has a solution for my other problem, for my battery.

I did a test and it reveals a 4890mah battery capacity instead of the 8500 mah this model has normally .

From 45% battery remaining, it empties in less than 10 minutes ... (A process "over-Counted" is then present)

My programmer and the cable arrived, but I still can't flash the new BIOS.

Everything is conencted but the flasher stay at 0%...

Any ideas?

My EEPROM is 25LQ64 (Gigadevice)? Does this chip need any special settings?

I still didn't desolder the battery. Maybe that's the problem?
[Teclast X98 Air 3G] Mikha777:
The battery should not be the problem from my experience, do you used the and drivers and software from my tutorial ?

If not try it and let me know but double-check the clip lot of time it's the culprit once the CH341a software and Drivers version are the right one ! Let me know how it goes !
[Teclast X98 Air 3G] bo2000:
Hi,

yes I used your guide and your software.

I also tried a different notebook. Same results.

The clip is looking good (see attachements). But maybe I should solder some wires directly onto the BIOS-pins?

3. On Android version how can i add 2 accounts (2 deferend Gmail users/accounts and each one to be separated from other? I need one account profile for my self and one for my wife.)

4. And last question does mirek190 had any rom that can make that tablet a beast??

Thank you in advance..
[Teclast X98 Air 3G] Mikha777:
What happen exactly at each step ? Also be sure to align Pin #1 of the chip correctly :cowboy:

1)With the CH341a software running plug the CH341a into your computer. Make sure that the Chip type is "25 SPI FLASH", the Manufacturer is "WINBOND", and the Name is "W25Q64BV".

2)Press the "Detect" button. It should detect your bios chip. If it reads unknown then you are not hooked up correctly.

3)Press the "Read" button to download what is currently on the bios chip

4)Press the "Save" button to save this locally on your computer. Use a file name like "t01_bad_flash.bin.bak"

5)Press the "Erase" button to erase the chip. This won't take too long.

6)Press the "Blank" button to check that the chip is now blank. This will take a little while. Watch the progress bar at the lower left corner of the window. Continue when it reaches 100%.

7)Press the "Open" button to select the bios dump you wish to write. In my case the file was named "EMBEDDED_OEM_BIOS_DUMP.bin".

8)Press the "Program" to start writing the new bios to the chip. This will take a little while. Again, watch the progress bar and continue when it reaches 100%.

9)Press the "Verify" button to make sure that what's been written on the chip matches the buffer(the bios dump you wrote to the chip).

10)Unplug the CH341a from your computer's usb port, then unclip the test clip

[Teclast X98 Air 3G] bo2000:
So there is no way to use the programmer just as it is?

In none of the tutorials I've read was this problem mentioned.

So maybe I have fryed the chip?
[Teclast X98 Air 3G] kostas-k:
I have heard about the voltage, but never had problem with flashing. I have flashed the BIOS chip many times with that programmer without any problem at all and with no modifications, just used the programmer as is. For flashing after presing Detect button to detect the chip, I pressed Read button, open the BIOS file and then pressed Auto to start flashing.

[Teclast X98 Air 3G] sikke1:
3.3v flasher works fine, its been done several tablets. It wont fry the chip. 3$ flasher in my photo, soldered directly to the 1.8v winbond.

You can look the pin order from original clip. Number 1 is marked in the winbond chip. Your flash is correct when you can read back exact same data. 1) open the program and load the rom then take screenshot 2) detect, erase and flash the rom 3) close and open program again dont load the rom but read it from the winbond. When you get read function to show what you have in screenshot your rom is fine. I had several partial flashings where read back resulted only half the data... Maybe weak solders and very thin connections to the flasher. It was pain.

If you cant get any read results its not working. While battery soldered, my flasher tried to flash, but all got corrupted and never any read back results. Maybe because 3.3v flasher i do not know..

After flash, tablet is really slow to boot, dont be unpatient and hit power button too much. You should connect the tablet to computer USB it charges from there and boots in 1-5minutes with Teclast icon. Remember to solder back the battery first. I think on my final try it took minutes to start.

I had several trys and didnt get the tablet to always boot. I actually got it to boot but then it died on me ofc I was unpatient and started to flash again.... Plugging in charger and wait seemed the best way.

This is X98 Pro. 14nm cpu core there.

[Teclast X98 Air 3G] Mikha777:
Technically you are right but in daily practice your are wrong, I know lot of users that used 3.3V on 1.8V SPI and never seen anybody fried a component, I don't say it can't happen or have never happen but the "in the field" it don't happen 99.5% of the time.

But soldering wires directly on the chip involve lot more risk to destroy the chip for the "casual user" than using 3.3v on SP1.

The Main Goal of using a "cheap" CH341A is to make risk/reward of the repair affordable. Also like it was told many times on this thread most "cheap" 1.8V CH341a Programmer don't work because you can find drivers and other that could work will be > $75 so the risk/reward begin to be less attractive. :cowboy:

Instead of soldering wire directly on the board it would be less expensive and more safe to test your set-up with a brand new Winbond W25q64 chip @ 0.99cent/piece ;) If the flash work with the new chip you will know that your setup is OK. After if the W25q64 is damaged you just put the new one carefully or ask to somebody that is accustomed with soldering surface components .

That was my 2 cents advice :cool:

---------- Post added at 08:09 PM ---------- Previous post was at 07:57 PM ----------

Worst case the data are "stuck" in the chip (can't be programmed/writed) you have to use a new W25Q64 (cost 75cents to $1.50) and program it before soldering it on the board and ask to somebody that is accustomed with surface mount soldering to solder it to minimize the risk (like fry some small capacitor/resistor around the W25Q64. :o

I bought my flasher off of AliExpress. 1.8v. The description is "EZP2010 high-speed USB SPI Programmer support 24 25 93 EEPROM 25 flash bios". Not $3, more like $12. Came with all software on a CD as well.

For the past days I face a weird issue with the Mirek v7 ROM on my X98 Air 3G tablet.

I used to run Mirek v7 ROM for the past months, after upgrading a previous version of the ROM without wiping data.

I chose to switch to the Lite version of the v7 ROM, and installed it with a full data wipe.

After the installation I only configured WIFI and my google account.

I just installed Facebook and Facebook messenger from the play store, and both crash (they didn't before my android ROM reinstallation)

So far those are the only Android application where I face this issue, and I don't face any issue under Windows.

can you also tell me how to install the rom? the links on the footer are not working
[Teclast X98 Air 3G] Mikha777:
The best thing to do IMO is to write your license number on a paper and download the ISO file (32Bit Version) from Microsoft in your language, this way even the recovery environment will be in your language. If you just add a language pack the user interface will be in your language but the recovery environment will be in Chinese, so if you need to use it it will be very hard unless you read Chinese ;)

The best is a Fresh Install in your language copy the 32 bits Windows 10 ISO file in your language with Rufus on a USB drive and boot from the USB Drive to install :cowboy:
