com.android.systemui keeps crashing when charging level at 100%

Hello,

recently I get my Teclast X89 tablet, but unfortunately it appeares to have a problem. When the battery charging level comes to 100% (at 99% everything is OK) tablet becomes totally unusable. When the screen is switched off it cannot be waken up and when I use the tablet a window pops up telling that "Process com.android.systemui has stopped", like here:

After restart everything is OK, but it really grinds my gears. Maybe someone know how to fix this problem?

Please halp!

Hello Deen0X, thanks for your reply and explanation. Now i know it seems to be a general problem. If you have a tablet like this connected standby is activated and with this hibernate is also enabled by default (you should find a hiberfil.sys file in C root, its used for fast boot option) so you normally can hibernate with the command i mentioned before: "%windir%\System32\rundll32.exe powrprof.dll,SetSuspendState" this works fine for my other acer win 8.1 tablet (OOTB system) directly after install. But not for the Teclast x89. Of course having a normal boot and restore from hibernate is pretty same time, also fast boot does not have that big impact. I like hibernate because it "freezes" actual system status without draining battery after that.. i often have several browser windows opened, some other metro apps and i like to resume to that state and not to have a clean boot.

[MENTION=3410188]Deen0X[/MENTION]: could you check your event log? Is there also the message that device could not restore from hibernation?

So keep me updated, or maybe anybody else can try the "%windir%\System32\rundll32.exe powrprof.dll,SetSuspendState" command to hibernate the teclast x89 dual boot. It will not harm the device. I have the experience if hibernation is disabled and you run this command it simply locks the screen..

Thx and br

I have the same problem. When charging comes to 100% tablet screen start flickering and the same error appears. When battery level drop to 99% all is ok. This only happen in Android. In Windows is all normal, so i think it is the problem in Android. So, for now it's the best to charge tablet in Windows or when it is totaly turned off. This is a bit annoying because i want tablet to run in Android without any problems. If someone knows how to fix this problem please HELP !
[Device Reviews and Information] Deen0X:
sorry for the delay.

I created a shorcut to

"%windir%\System32\rundll32.exe" powrprof.dll,SetSuspendState

run and... get corrupted my D: (microsd)

i moved all my data to D:, for free space on C:

now, i'm trying to fix it. XD

[MENTION=1060365]danthekilla[/MENTION]

i get few times this problem.

i really don´t know why this happens, but fortunatelly, i found a solution.

turn off your device

plug a keyboard, go to bios

you will see that there is selected "Microsoft Windows" as boot manager, change to "OS Loader" (sr something like this), and set other boot devices to disabled.

restart.

you will see the OS selection screen. select windows, and all will work ok again.

i don´t have any clue why this solve this problem, but really solve (almost for me)
[Device Reviews and Information] Arangato:
Hi Deen0X, oh microSD corrupted? Sounds not good.. I would not reccomend to move hiberfil.sys file to other drive than C :)

The x89 (e6ed) is compatible with the air II dual boot bios and the image files of the x89 dual (e7ed). But windows has a battery drain problem (10%/hour) with that bios. Android gets unstable on charging, after it reaches 100%.

after flashing the x98 air II dual boot bios, you can follow this guide: http://manguiro.blogspot.de/2015/03/guide-teclast-x89-installation-guide.html

com.android.systemui has stopped

Hello,

Maybe not I'm the only one who faced this issue, but every time the tablet is charged to 100% I face the following:

- if the tablet was in a screen-off state when I unlock the screen the com.android.systemui has stopped message appears and the wallpaper is blinking (as well as changed to something default wallpaper).

- if the tablet was in turned off state (or booted to windows) the same message appear after the reboot.

Also I'm quite interested about replacing the GUI or reinstall some stock android without the zillions of chinese bloatwares. I know I can uninstall most of them and use a 3rd party launcher like Nova or Apex (I'm doing it now), but a clean and fresh install would be much better.

Thanks in advance, regards

Teclast x89 bricked ?

Proud owner of a teclast x89. Have rooted it (kingroot and iroot) and then uninstalled various chinese apps (eg tui). Then backed up using titanium. Then decided to restore from the backed up files only for the device to become semi - bricked. By this I mean that I can still boot as a window tablet but when attempt as android it loops and is stuck on the booting screens. Is there anyway to reinstall the stock rom so can use as a android tablet ?

Thanks in advance,

Andy

Hi, owners of Teclast X89. I am very keen in getting this tablet as well for playing some non-demanding windows games.

May I know what is the screen on time you are getting for a video loop test?

Did you guys get a case for the tablet? Will the ipad mini's case fit this tablet?

How's the data transfer speed for class 10 micro sd card in this tablet? I intend to install my games in the sd card to minimise space usage in the main memory. Will both Windows and Android see all the files in the SD card or do I need to partition the card like the main memory?

Thanks in advance.
[Device Reviews and Information] djshorty:
On post #16 you have link for guide and download links. I install only android part and dual boot screen appear. I didnt need to install windows that was ok.
[Device Reviews and Information] gadget46:
I will try as soon as possible.

Thank you very much :)
[Device Reviews and Information] suitengu:
Same here on a stock E7ED, it's a bios problem ?
[Device Reviews and Information] betunyo:
I have the same problem and i think this is a rom problem. Maybe the battery stat calibration will solve it, but i have not tried yet.

x89hd

I know I m out off topic but I can't find any info about my device.I have this tablet about a year now and still have no support from taipower.I have sent many emails but no reply.

My only hope is from uses of xda.the tablet x89hd(h21c) has only one firmware 4.2.2.

Is it possible to flash a dual is from x89?

I tried to follow the guide from x89 but when I press power + volume up and volume down at the same time the table boot as normal and do get in any fastboot.I would like any help from experience users.thank you.

* to be honest I'm very dissapoint from taipower to let down x89hd.
[Device Reviews and Information] suitengu:
I think the same, i have the same bios as Deen0X so it's definitly not a bios problem.

I tested to unplug the battery for 15 min, no effect.

I will follow Deen0X's instalation guide because i brock my windows sleep. I will see if a clean android still bug.

edit: same bug after a full restore, we need to wait a new android firmware.
[Device Reviews and Information] Grillface:
I am also having the same problem 'systemui has stopped' when my Teclast X89 (E7ED) charges to 100% battery. I have tried contacting both Teclast customer support and Geekbuying with no response. Any luck with flashing another ROM? If anyone finds a remedy it would be much appreciated.
[Device Reviews and Information] suitengu:
I see on his website that Deen0X have the same probleme. It can be bios or android relative. I think it's not the bios because it works ok on windows.

I think it's a bug in the 1.06 teclast android rom, maybe we can instal X98's rom. If someone speak chinese he can see on bbs.teclast.com if there is a solution (google trasnlate is to awfull).
[Device Reviews and Information] Grillface:
Sounds like we've tried the same things. I applied for a refund/replacement as I only received mine on the 22/3 but I feel like it might be a common issue with all Teclast X89.

Has anyone tried using DeenOX's guide on reflashing android to see if that rectifies the problem?
[Device Reviews and Information] suitengu:
I have tried it doesn't work, in fact DeenOX also has the problem.

I have seen on a korean forum that we can use X98's systemui.apk and systemui.odex, i need to test.

edit : i have just extracted systemui from the c6j6 official rom
[Device Reviews and Information] Grillface:
Sounds like you are ontop of it, let us know how it turns out. I wonder how many Teclast X89's have this problem
[Device Reviews and Information] suitengu:
I have rooted my x89 and replace systemui.apk and systemui.odex with the files i have just posted on the forum.

All run fine, no inteface problem and no bug at 100% charge !
[Device Reviews and Information] Grillface:
Nicely done suitengu!

Would I need to flash another Teclast Rom on my stock X89 first or just do the rooting part of DeenOX's guide?

I tried installing the .apk without root but wasn't able to do anything with the .odex I assume that needs to be put in a system directory?

Sorry haven't had any experience with .odex files,

Thanks suitengu
[Device Reviews and Information] suitengu:
1: you need root, you can use vroot or the X98's toolbox (you can use the same tutorial as the X98)

Now with root explorer or es explorer granted with root acces

2: copy paste systemui.apk and systemui.odex at the root of "system"

3: set permissions rw- r- r- on the 2 files

4: cut paste systemui.odex in system/priv-app

5: cut paste systemui.apk in system/priv-app

6: now systemui will continuously crash, force a reboot (long press on power)

Never instal a system app by the normal way, it does not work and can bug you system.
[Device Reviews and Information] betunyo:
Thx! I'll try it. Just 1 question: if somthing goes wrong, is it possible to flash just the android firmware or you have to reflash everything (android, dual bios and windows)?
[Device Reviews and Information] suitengu:
Deen0X's first part guide flash only the android part and doesn't touch the windows partition.

The only thing that can bug in the process is if you delete (and not replace) systemui.apk.

hello

i have the x89 and till now it is doing great at both os's and root

but today i came up with an issue.

my hdmi is not working at android and at windows.

anything that i can do about it or it is known problem?
[Device Reviews and Information] Grillface:
You deserve a medal

Worked perfect, for anyone else that struggles with the rooting: I had a issues rooting as I tried using the X98's toolbox but that had adb problem. In the end I used iroot and a combination kingo android root following this video ww.youtube.com/watch?v=FL-SV8UatOU which did the trick.

Charged to 100% and no issues with the systemui or any google.locations/services errors!

Any clue which of the bloatware apps can be deleted safely - or more importantly which ones can't be?

Thank-you suitengu you are a legend!

In case you are still having this issue (as I did) try this:

Instead of press VOL- & VOL+ at the same time, just press VOL+ and voila!

New problem: teclast x89 not charging when ON

Solution: Drain the battery to 0% (until not being able to reboot) and full charging it when off

Disconect the battery do nothing even if someone on the teclast x98 forum report that it works.

Some news to, x89 and x98 air 2 and 3g have the same motherboard, only peripherics change. So the fact that we can not charge the x89 when using an usb otg hub is related to the x89's bios.

To enable otg charging we can surely use the x98's bios. But it's a pain because i think it will screw windows activation.

This teclast has a realy good hardware but it lack of a coherant software.
[Device Reviews and Information] Neo Polonais:
Hi guys, i'm a part of happy owners of the x89 e7ed.

I experienced the 100% battery bug on android and i'm about to try files given by suitengu.

For people having a boot loop on android try to press vol+ and vol- when booting android, it will boot on safe mode and then try to restore your tab from the settings (worked for me after i tried to install xposed)

Have anyone get a CMW or TWRP to work?

And how can i change the keys on bottom bar, like volume and camera that i don't need?

[edit]

I found that ultimate dynamic navbar is the perfect app i wanted
[Device Reviews and Information] flow28:
Same problem

Hey,

I have experienced exactly the same problem.

I tried with two different micro HDMI cables (micro HDMI to full HDMI adapter, angled micro HDMI cable) and three external displays (two Samsung, one LG), no luck.

The HDMI of my Teclast X80h, which I ordered as well works flawlessly.

All drivers for windows are installed and up to date and android doesn't even need additional drivers AFAIK, indicating a hardware problem probably.

A return to the reseller is impossible from my side.

Can I run USB LAN + USB Sound card on this device? Anyone can confirm?
[Device Reviews and Information] gufte:
Hi guys,

I'm a little confused and hope you can help me. Is there really a Z3736F version of the X89 or does it always only come with a Z3735F?

Thx in advance
[Device Reviews and Information] flow28:
Was any of you able to install Xposed on the X89?

The following method taken from the X98 Air forum doesn't work, I get a bootloop everytime.
[Device Reviews and Information] suitengu:
No problem but you will not be able to use an usb otg hub and charge at same time (we need to find another bios in fact because it work on X98)

Mine is 35F, it seem that some vendor proposed a 36F version. Maybe it's the refurbish old one (the e6ed win only) flashed with the dual boot. Or Maybe there are two version (it would be realy surprising).
[Device Reviews and Information] aitnog:
the x89 win (e6ed) has a Z3536F and the x89 dual (e7ed) has a Z3535F. IMO they changed the processor because of the overheating issues and/or the costs.
[Device Reviews and Information] flow28:
Are you sure, that charging and OTG don't work at the same time?

Not even with the special hub, reported working (charging+otg) for the X98:

"Universal usb OTG Charger HUB cable for Tablet PC thinkpad 8,X98, M80ta,WT-8,Miix2,ME-400C,V8P,T100TA,W4-820,V975I,more models"

(link not possible yet, just google or search for on aliexpress)
[Device Reviews and Information] suitengu:
Maybe with the hub with the 3 ways switch. I have this one and it does not work : http://fr.aliexpress.com/item/NEW-O...ombo-USB-2/2054513034.html?recommendVersion=1

i just did this

set the permissions to rw-r-r at both and after that i cut one by one and paste them in the folder but i had no systemmui crash . i did reboot and now waiting to get full charge to check it.

just for the record

i have the x98 dual os bios on my x89 with the touch option at the begining.

my only problem still is that i have issues with the hdmi
[Device Reviews and Information] Neo Polonais:
Hi guys, i need some help.

I messed up with my tab and ended with a fully formated hard drive with some buggy windows.

After that i managed to install win10 but i had no drivers.. so it was unusable.

Then i managed to fully reinstall the original oem windows with bing.

But each time i tried to do the boot command PW + vol- + vol+ i have the "Entering DnX mode" message but just for a sec, then windows [or the shell] boots, i can't stay on that screen so i can't flash android.

How can i flash android?

[edit]

\o/

I flashed X98 Air 3G Air II Dual boot bios [with touchscreen] an managed to get into fastboot mode and i think android is installing (:
[Device Reviews and Information] Neo Polonais:
Fuc*k, i can' turn my tab on anymore..

I used toolbox.cmd to flash bios, everything went fine until i reboot.

When i try to turn it on、 nothing happens but some chips getting hot..

I can't connect it to my pc

I think i killed my tab..

[edit]

So now i ordered a x98 air II and some stuff to flash the bios chip from my x89, hoping it will be that simple otherwise i'll have to change the chip for a new one [some peoples on chinese teclast forums already done that]

and i'll use this software

http://gq-usb-programmer.software.informer.com/

it seems to have a W25Q64 chip
[Device Reviews and Information] Grillface:
Sounds like you've had a worse case scenario. Let us know how it turns out.

I was originally interested in upgrading or at least re-installing a different version of windows on my x89 as the current windows OS had trouble with bluetooth and wifi dongles, not to mention potential Superfish style viruses built into the Teclast windows OS.

Now i'm hesitant to change the windows OS partition as the possibility of bricking or losing the android partition without the backup of proper English documentation.
[Device Reviews and Information] Neo Polonais:
Don't worry i turned mine into a mirror because i was flashing bios, [too many times? wrong file? i don't know] after i successfuly flashed bios from X98 [with touch screen, no more otg keyboard needed]

I wasn't able to install win10 from win 8 "because this PC uses a compressed operating system", i had to run an install from usb stick and due to bios, only 32bit os..

but when i managed to reinstall win8 with bing image i understood that the most important are the WIMPART.TXT and WIMPART-PRE.TXT files

for windows only tab, WIMPART starts with that

select disk 0
clean
convert gpt
create partition efi size=100
format quick fs=fat32 label="System"

I was never able to get a dual boot from that file because it erases all partitions before installing the image

and for dual boot, witch i didn't had time to test

select disk 0
create partition efi size=100
format quick fs=fat32 label="System"

So i guess that if you format only windows partitions it should be good for a fresh 32bit windows

the original x89 dual bios is available in the official teclast forum. this way i turned my x89 win (e6ed) into a x89 dual :)

Hi suitengu. I updated my installation guide, and add the steps you indicated for solving the battery charge problem. (figure you don´t have problems with this, quoting to you on the article.)

Thanks for the fix!
[Device Reviews and Information] Deen0X:
Hi.

can you give a link for the bios?
[Device Reviews and Information] aitnog:
http://bbs.teclast.com/thread-389148-1-1.html

the first post has an attached file which contains two folders - android and windows

the android folder seems to contain a basic bios to install android as discribed in the official teclast howto - I did not test it.

the windows folder contains the dualboot bios and some scripts to flash it from another windows machine to your x89 (booted in android with enabled debug mode and connected via usb to the windows machine)

after you have flashed the windows bios you can install windows as discribed in the official teclast howto.

on boot you can use vol+ to change the os and vol- to select and boot it

btw. teclast forum needs registration and a dummy answer to the thread to see the first post completely and translate.google.com (or chrome) is your friend ;)

[Device Reviews and Information] Shrelf:
Hi, thanks for the help so far as i got here because i also have the 100% charge bug.

I don't know if I understand your post correctly though:

Does this mean that when I install the systemui app from the x98, my x89 won't have the 100% bug anymore but instead will not charge unless it is switched off?

I hope that I misunderstood as I really would like to get rid of the bug without getting another one;)

[MENTION=6429918]Arangato[/MENTION]: the left button says "online update" and will check if an update is available,currently returning "undiscover new version" for me . the right one says "local update" and will open a file browser to pick an update file.

I got the translation by using the camera/image recognition feature of the Google translator app on my phone, which is pretty handy for cases like this where you cannot copy and paste the text.
[Device Reviews and Information] suitengu:
Shrelf> battery bug at 100% and the no charge problem are not related.

The no charge problem can happen when you play with an incorrect usb hub.

Ok good to know,thanks!
[Device Reviews and Information] ntemis21:
since i copy paste the new files for the charge bug i am having some issues, at first i said ok first time maybe it was just bad luck, but the it does it every day,

systemui stops working most time and i must hard reset it and it does it if i let it drop under 15% battery
[Device Reviews and Information] suitengu:
I don't have the probleme under 15%, are you sure that you have past the 2 files and no only the apk?
[Device Reviews and Information] Neo Polonais:
Maybe you didn't put the good read/write rights, i didn't do that part and wasn't able to use system ui until i figured it out.
