@alebarce I’m trying to find one that might hold on better. But they all look the same on the internet. Let me know if you find anything and i’ll do the same. I need to restore this tablet so it’s not a $231 brick, wish I never tried the v1.13 bios on the K9C3, but it worked just fine on my X98 Pro (K9C6).

Hello Chris and all friens here,

So would mean that with these I could wake up My X98 pro K9C6 ?

Shortening my story is that :
– My K9C6 started to have problem the day I tryed to modify the “power managment” about buttons rules in the WINDOWS part… It made mess TOTALY even in the Android mode looking like this I’d like to understand the reasons…
As from there, windows crashed and dual boot menu dissapeared and no windows anymore, the tablet was booting LONG BOOT 3 minutes to open android mode… BUT the tablet seemed unstable greatly when charge more than 80%… it was restarting by itself repeatidly … but android was working well from 0% to 80 % battery charge… (77 – 80 %)
What it was coming from ? the values I changes when Windows was still alive did change something somewhere ???? No clue…. 🙁
From there I rooted it and installed mirek V6….  Android was working same well but upper dans 80% battery problem still there, very unstable restarting by itself mostly when not using it or when try sleeping mode… ANY CLUE ANYBODY PLEASE ?
I really read all from everywhere I can’t understand what to do… And finaly, this unstable mode at when I was at 97 % battery the tablet switch off and never started again… I am on mirek V6 1.5/56 Gb installation, and bios 1.14… I wanted to downgrade the bios to 1.13 that is looking better than the originakl 1.14 I had… but actually, dead tablet is a bit annoying…
Do someone have any answers about my experience ? What would you advise please  ?

No. even switch on it does. but the problem is that when you touch the power  managment on windows side it make crazy things to the kernel and this is dead after… I still gone on Mirek V6 1.5/56GB android only but still havin problems… when charge is about 88% and more… the kernel a like “fighting together” and tablet can’t stay sleeping mode … it restart all the time because this stupid kernel from windows is somewhere again… or that is bios need to update maybe….

How do you update the bios on this one ?

All is easy to do BUT when I enter F7 the menu popup with my USB WINPE (with all needed files on it from BIOS’s zip file and else..)appearing… but as I am reading there should be a shell appearing on the tablet when selecting the WINPE right ?  Mine is simply rebooting when I select the WINPE pen drive…. Any help please ?

You need a keyboard plugged in to “Hold F7” if that still doesn’t work.. Boot into DNX mode and reflash the android image (VOL -/+ while powering on), this will wipe your data though.

He is still looking to have nearly same issue has I have… and he saying that even F7 not opening the bios as before.. And DNX mode not appearing anymore… So what can we do at such state please ?

Not sure this is any help but I remember getting a similar error on my X98 Air 3G and it turned out to be (of all things) low charge. Hold down the power button for about 14 seconds. Plug it in and charge it overnight, then try again. Also if it’s not broken, I don’t really recommend flashing bios updates. Always a risk of a brick. If all else fails you’ll have to do a USB bios flash.

Hello,
I have same problem… Did this really helped you to find back the dual boot menu and else ? Because just before mine started to “android optimizing apps” reapeatidly for hours….  Most problem with my x98 pro is also that even I never managed even under android when it’s back on I never managed to conect ADB… “device not recognized” and else… turns me crazy as I want to root ans flash it really..

I solved this problem, use 2.5V and 3A charger, it will help u

I also bought a 3A. 5V charger but the problem is still the same…

My issue is that charging well under windows BUT charging as SLOW USB CHARGE when on Android… And a good charger 3Amp did not solve that issue….

Maybe need 5.3 V charger ? Can you please anyway send the link where you bought your charger on photo please ?

Hi and thanks for your answer… but russian links… even is I speak basic russian … this will be difficult sorry -( Did you find how to correct this problem of charging under android mode ???

[Stephane Rousseau]

Hello everybody,

I start to become crazy now… My X98 Pro (K9C6) was working well but since yesterday it is very difficult to charge under Android.. that is detecting only “USB charging mode” and really not want to accept the power of my AC Power supply.. I checked and with others AC power (all 2.5 A. SAMSUNG and others…)… under android only keeping sloooow charging mode “USB Charging”..

NOTE : if I switch to windows 10 mode It charges correctly…

What went wrong in my android system ? I reinstalled it twice to factory settings… problem still there…

[Stephane Rousseau]

Hello,

I have the same issue about the : “sometimes it enters a state where it only draws 0.45A.”

But your trick as you mention is not working for me (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.)

Any help ? the crazy thing is that on windows boot it is charging OK… but under android there is no way ! it stays a 400 – 470 mA

I’d be very grateful for HELP !

Thanks,

Stephane.
