error flash mirek lollipop v5 rom

Hi [MENTION=2198172]mirek190[/MENTION]! tonight i tried to flash mirek lollipop ultralight v5 rom on my air 3g 32gb C9J8 1.07 with .bat file.

I choose the first option (flash rom&wipedata). the tablet reboot in droidboot, starting erase system, data and cache but after there the tablet is stuck with message error "could not open /sys/devices/virtual/backlight.

now the android partition is in bootloop and only windows is available and i can use it.

any advices??? thanks guys!

1 - I'm not quite sure what you mean - but my is smooth ...

2 - it is problem with x86 architecture - the game not handle x86 cpu
[Teclast X98 Air 3G] jsager33:
1. Example: from my home screen. If I drag my finger slowly across the screen to the left to get to the next screen, the screen does not flow smoothly. It looks jumpy. Is there a good app to do a screen recording so I can show you what I mean?

2. I keep forgetting that we are dealing with a different architecture. I'll take this up with the app developers.

I have Mirek 190 4.4 v4.2 ROM how boot. to droid mode?
[Teclast X98 Air 3G] mirek190:
If you want to record the screen use that built feature from android system.

To activate it find it in gravity box.

Via my app to flashing or use some app from Goole play or when the tablet is off then keep volume - and power for 7 seconds and release .
[Teclast X98 Air 3G] chrissss91:
Well, my battery is almost everytime at 99 %, it's like if it was charging/discharging/charging/discharging and that screen wakes up at every change, weird ...

I don't know how to fix it, and it seems strange under Windows to.

Maybe I should wait my battery to be empty and charge it to 100% after or delete some files related to battery charge ?
[Teclast X98 Air 3G] Mikha777:
Ok I see., When I have some time I will look for the Chinese character String in the BIOS.

BTW: Sometime there is leak... :p
[Teclast X98 Air 3G] dark53:
Keep vol- and power did not work app ? your app flash.bat or other

ITS OK no problem I installed app Restart and work.

I have another question if you can install Windows on the tablet as the only system.

[Teclast X98 Air 3G] h0t1ce:
I've been having the same issue. I can't have my tablet in my room at night charging because the screen keeps coming on and off.
[Teclast X98 Air 3G] Stremon:
Same issue for me too...
[Teclast X98 Air 3G] kiwiman2000:
I think these batteries have temp detection on them which turns of the charging if gets too hot

and when cools enables again and I notice when that happens the screen comes on.. atleast to show battery level

probably some xposed module that can control that.

another TIP was replace the 2.5amp USB charger it comes with a 1amp one.. thus slower charging but

less heat.. might be a simple solution for night charging..

or place it in the cupboard at night if can :) (or cover screen)

=---------------------------

Another question.......

HAS ANYONE tried to RUN VMware on the windows on that tablet.. I doubt it supports as the chip needs

virtualizing correct??
[Teclast X98 Air 3G] tecknight:
Chris,

I take it from your freeze .apk comment, that you are having this problem in Android ?

Which android ROM are you running ?

I am running Mirek's latest lollipop and I am not having that issue..

Here is what I suggest

Connect your tablet to a PC using a USB cable.

Open a command prompt

Wait till you see the issue happen.

On your PC, Type the following, followed by ENTER.

adb logcat > logcat.txt

Post your logcat.txt here and I will see what I can find. I will compare it to mine and see what is interrupting your sleep mode.
[Teclast X98 Air 3G] chrissss91:
Thanks Tecknight for the tip, I will try this when my battery will be charged at 100%.

Right now I'm trying to do some battery calibration (How to calibrate Android device battery with root access).

Seeing that I'm not the only one with this problem and that you and Sized already noticed wrong charge capacity reassures me.

My USB port seems fragile and I was afraid there was a matter with it. I really hate charging with USB port.

[Off topic]My former (but still alive) tablet is one of the famous HP Touchpad :good: bought 4 years ago and it has an induction charger which is just an awesome thing for a tablet IMO.

No cable to plug ==> no usb port damaged, tablet can be used h24 as a photo frame, no need to watch if tablet should be charged, just put it on the charger and leave it :good: After 4 years, with I think

at least

3 years of screen on, battery and tablet are both still OK.

I don't understand why there is no more devices compatible with this technology, even if charge is slower.
[Teclast X98 Air 3G] oam_xda:
C9J8. Upgraded to mirek's Lollipop 5.0. Bios 2.02. Camera's are not working (and because of this Instagram crashes on start).

However, I did see one guy report that his C9J8 camera worked with lollipop 5.0. I wonder how...
[Teclast X98 Air 3G] tecknight:
You have an HP Touchpad ??

I used to have 2 and just about all of my friends had 1 as well.

Bought for $99 when HP gave up on it.

The HP Touchpad is where I learned Android kernel and ROM development.

I must admit, I LOVED the wireless charging it had and it was a solid (if heavy) tablet.

Yes, my X98 continues to show a "design capacity" that is half of what it should be.

Once it broke, it continues to show incorrect values.
[Teclast X98 Air 3G] tsvetanm:
Okay, then I guess I will have to start reading regarding this programmer...

I noticed that when I press vol+, vol- and power, the tablet does not show anything. But when I touch the back after an hour, it is warm. Could it be some screen related problem?
[Teclast X98 Air 3G] dark53:
while flashing rom lolipop 5.0 mirek190 with 2.2 flashtool program does not connect with the tablet in the tablet shows the message "coul not open / sys / devices / virtual / backlight", any solution? I currently have rom mirek190 4.4v.4.2 I can not use the MFT because you can not open mode DNX

the current 4.4 ROM v4.2 (mirek190) after trying to flash the Droid mode after each shutdown, reboot your tablet I have to again enter the wifi password before this there was what could have happened? something wrong with ADB interface in devices manager calling that drivers for this device is not inatalled.

All ist OK i must install Intelandroid drv v.1.10 Loliipop is super:)
[Teclast X98 Air 3G] breedovsky:
Hello again.

I tried to get android from windows, but I could only get in dnx mod, tried flashing rom, but in 5-6% it failed. Im not sure, but I think it was boot.img? Something like that.

I was looking for solution, but didn't find anything usefull.

PS. Droidboot not working (vol- + power).

Is there anything to make it work again?
[Teclast X98 Air 3G] chrissss91:
Yes, I bought it only for its price (128€ for 32Go), not knowing what I will do with a tablet.

I must admit I tried to buy another one but too late .

A book could be written about the story of this device and all the developpements made by the community (my first steps on xda) !

I must admit too that I really like this device, the only lack today is its 512Mo of RAM.

And you know what ? Clash of Clan is smoother on my TP than on my x98 :silly:

btw I'm trying to collect catlog but unfortunately it fails :

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
[U]Unable to open log device 'main'[/U]

Is there something to activate under Android ?

I forgot to mention, it's a C5J6, Bios 2.02, Win10, Mirek Lollipop 5.0
[Teclast X98 Air 3G] tecknight:
Chris,

Try:

adb root

then try the

adb logcat > logcat.txt

If it still gets an error, try:

adb shell logcat > /storage/sdcard1/logcat.txt

Then pull the logcat.txt from your MicroSD

and YES,

Someone should write a book about the storied HP Touchpad

I actually did some of the very first research into the Touchpad and how it was originally developed.

Did you know that the first touchpads off the assembly line were preimaged with Android (a recovery image) and they actually used this initial android recovery image to load up the WebOS image ?

2 or 3 of these Touchpads with android on them actually made it into customers hands, and we had them backup the image.

That was our very first step in developing a working Android image for the Touchpad

Nodoka,

The only way to get your Android partitions back will be to boot into DnX mode, then use MFT and select an XML file that says to flash with partitioning. It will flash the android ROM you selected, but will delete your Windows installation. You will then have to reinstall Windows.

I couldn't get Onenote to work from fresh install with mirek Lollipop 5 either, but it worked well when I restored it from a Titanium backup which was made in KitKat just before upgrade.
[Teclast X98 Air 3G] chrissss91:
Yes, knew that and it's amazing :

1 - That they developped on Android

2 - That they sent these devices to customers :eek:

Well, still no luck.

adb root :

adbd is already running as root

adb logcat > logcat.txt :

Unable to open log device 'main'

adb shell logcat > /storage/sdcard1/logcat.txt :

says something like "Path can not be found" (mine is in french [IMG="French"]http://smileys.on-my-web.com/repository/Flags/france-flag-27.gif[/IMG])

[Teclast X98 Air 3G] tecknight:
do this one then:

UPDATE about Fixed BIOS 2.05 for X98 with GC2235 Front Camera

UPDATE about fixed BIOS 2.05 for X98 with GC2235 Front Camera

The problem with BIOS higher than 1.03 is that the front camera GC2235 is not enumerated in the ACPI/DSDT of the BIOS, there is only the OV2680 that is enumerated. So I will insert GC2235 device in the DSDT so it should be recognized and initialized properly on the Windows side since Windows use the ACPI tables to find the devices on the hardware.

For Android/linux I don,t know a lot about it since I don't use it, I know DSDT tables are used too but I don't know to which extent. :confused:

If I'm successful to build a new BIOS2.05.bin with the modified DSDT it could work on both OS Windows and Android, it's not easy (at least for me) to find the tools and knowledge I need to be successful but I can say I'm very confident. :cowboy:

For the Windows side I can inject the fixed DSDT part in memory when windows start without modifying the BIOS, it's less elegant but it work. :D

Worst come to worst I will come out first with a fix only for Windows where the fixed DSDT is injected in Windows at start and later I will come with a complete BIOS fixed.

If you have any question feel free to ask. :cool:
[Teclast X98 Air 3G] cosmok82:
info about building

Excuse me Mikha777, you talked about "building", so I presume you got a source code :cool:!

Where I can download it? Is there a toolchain to compile this kind of BIOS?

Thanks in advance for your answer.
[Teclast X98 Air 3G] serpao:
Hi there.

I wanna ask a simple question here: Is it still a good choice the Teclast x98 nowadays?

I see that there is a lot of community here working on it, but im still undecided. I have read a lot about the tablet, and there are plenty of ppl not happy because the temperatures. Even i have read that the teclast turn off itself when watching a film, or things like that, only because the temperature.

I would like to see yours point of view.

Thanks in advance :)

Sergio
[Teclast X98 Air 3G] fresnillo:
The only toolchain is this one:

http://www.tianocore.org/

Probably we will be lucky with coreboot

Wrong automatic desktop rotation on Win10

Please. . . excuse me if I propose again a topic already discussed. Unfortunately English is not my language and search here for me it is very difficult. Sorry ...

After updating to Win10 Home 32bit, I have had many problems, some resolved, some still standing.

What I want to resolve now, it is the automatic rotation of the Windows desktop and wrong upside down. If active the automatic rotation, any rotation setting I put (90°,180°,270°), taking the vertical tab in the desktop overturns always 180°.

Maybe I have to update the driver of the rotation sensor? Or what ? If so give me the correct link?

PS

I find and read here, but dnt work for me . . .
[Teclast X98 Air 3G] mtr33:
:good: Nice work. So far I've not been able to fix the power drain on my HG6N by flashing a new BIOS because of the camera issue. I don't need android on my 32GB device, but the power improvements would be more than welcome.
[Teclast X98 Air 3G] cosmok82:
Do you say that Mikha777 used this toolchain? And the source code? Where I can get the souce code of BIOS 2.05 for example?
[Teclast X98 Air 3G] fresnillo:
No, you are asking about the toolchain and tianocore is the only one available with support for your processor. If you work with American Megatrends probably you could get it, but at this moment the only way is use an hex editor and be clever.

He has explain how he get the fix for this BIOS, and he has asked so many times about the parts which he needs to edit a flash dump, and nobody pass it, and they are in all flash eeproms, only he needed one dump and explit it.

There is not an official published tool by Teclast to compile the BIOS, or unlock the "x64 WindowsBoom protection". The only way is hexedit.
[Teclast X98 Air 3G] Mikha777:
See your PM. :)
[Teclast X98 Air 3G] RaichuBender:
I'm sorry for the late reaction. I wasn't at home for a few days so I was unable to let you know if it worked or not. Unfortunately, it didn't. It returns: "46 - Error: Problem getting flash information." Please tell me that third option if you remember.
[Teclast X98 Air 3G] UrielZ:
...

I have the same model (c5j6) and exactly the same problem.

tried 3 different headsets and the sound in all of them it sound like i'm in tornado...
[Teclast X98 Air 3G] Mikha777:
OK this one should work, it require a little bit more manipulation but it's easy to do. :cool:

1- You must create a bootable USB key, Follow the instruction here: http://www.sevenforums.com/tutorials/46707-ms-dos-bootable-flash-drive-create.html

2- Copy the DOS version of FPT (See Attachement) and the BIOS File in the Root of the USB drive.

3- Boot with the USB drive and at the prompt just type:

FPT.exe -f MyBios.bin

Replace "MyBios" part with the name of your BIOS.

4-

IMPORTANT

: At the end of the process press the power button 10 second and release it to make the tablet shutdown.

5- Enjoy !

Let me know if it work fine :o
[Teclast X98 Air 3G] cosmok82:
OK, I dumped my BIOS before and after the unbrick of tablet.

Can you suggest me some tool to edit the bin file?

If I have to work only with the hexeditor could be a problem.

PS

I'm looking for American Megatrends tools, but I think they aren't at disposal of everyone...
[Teclast X98 Air 3G] chrissss91:
Well, I had to do it in 2 command lines :

adb shell
dmesg > /storage/sdcard1/dmesg.txt

See attached file (there are a lot of things related to battery :crying:)
[Teclast X98 Air 3G] fresnillo:
Sorry, I could only suggest you hex-editors: http://www.wxhexeditor.org/ or http://home.gna.org/bless/ and be patient searching and splitting, a random change will not work.

They works fine on linux (bless could be sometimes hard, but it's beautiful for me).

When you finish flash with flashrom, I used a raspberry pi, wire-wrapping and the spi port, but in this thread there are tutorials with programmers and "tweezers" which could be easier. Test it and enjoy ;).

And yes, the American Megatrends tools are only available for manufacturer. It's not published for customers. This was the reason of the tianocore and coreboot mention. They are opensource.

Hello, I also have teclast x98 air 3g and I have a problem with touchscreen reaction on Android.

There is no reaction, but when i start Windows everything is ok there.

I changed android version but nothing happened. Do I need to change somehow some drivers?

[/COLOR]

Yes - install android my 4.4 and use special boot.img.

- before flashing replace that boot .img in ROM folder to special boot.img ( everything is on my gdrive. )

Hello again. As I understood I copied

2 files from your disck.

boot_touch_fixed_for_mirek190_roms 4.4.img

and

X98 Air 3G 4.4.4(C9Jx) mirek190_v4.2.7z

because my tablet is C9J8.

Before I flash, i removed (renamed) original boot.img file and replace it with _boot_touch_fixed........

Then I flashed using Manufacturing Flash Tool 6.0.43

I can't use your file FLASH_tool_Teclast_x98_air3g_and_2.bat

because for me volume- + power dont work.

But this problem still exists. Did I do something wrong?
[Teclast X98 Air 3G] mirek190:
Do you keep enough long that buttons ?

At least 7 second - and not every time is able to boot to droidboot this way .

Also you can start flashing from the android - only choose the proper option it that Flasher .

kingroot randomly fails

Hi

Ive rooted this teclast with kingroot via the pc.. took a couple of attempts (I think it got stuck on boot menu

or didnt reboot like it should during the root) - why not made chinese to eng version of it either.

anyhow root stuck for a few days....

ive noticed sometimes it looses root access... and rebooting from the boot menu brings it back

im at lost why if it goes straight into android it fails but from boot menu it works

for now I just reboot and hold vol+power and select droid option

ive tried srsroot failed to connect.. tried iroot aka vroot connect .. but seem to add crap to the tablet

and some rocket side icon.. which I remove the shortcuts and apps

im sure it was the offical setup not some malware version.

=== its about time google allowed root access with an offical tool built-in and stop control how we

want to use our devices.

also a simple flash method could be added.. where you boot from a menu with rom on sdcard

where it cant go wrong like.. with some form on internal roll back factory rom

X98 Air 3G - C9J8.

I have always had very poor WiFi connections in both Windows and Android. I get data for around 5sec, then nothing for about 10sec. Even when within a metre of the WiFi router. Have played a little with channels, different routers etc so think I have covered off all the basics without success.

I am presuming I have some sort of hardware issue. Is anyone able to provide some guidance on either how I can narrow the problem down or fixes I can attempt? Earlier in the thread (much much earlier) there were mentions of people looking to make manual improvements to antennas (as an example) but I couldn't find any subsequent posts with details.
