you can modify the Z3c so that it boot properly / boot into Android and not only in the battery indicator when power connection infects?

Hiii
I just want to confirm that weather it's normal or not?
1. When ever I connect my phone to power (While phone is switched off) USB/AC phone boots up to safe strap choice menu automatically without pressing any button & I can go to safe strap menu by pressing settings button or boot normally to phone. If i don't do any thing it goes to charging mode.
2. When I connect to AC power & at that time even if battery is not there in phone, it will boot to safe strap choice menu but wont boot further. whatever i press it will just boot again.
3. While connected to AC power after booting into safe strap even if I remove battery, safe strap works fine. I can browse through menu etc.
If that be the case then may be phone can also work like that with some tweaking, so for people like me who are most of the time working on laptops, they can connect their phone to charger cable whenever possible & reduce use of battery. It will increase the battery life also.
I'm currently on slimics 4.2, though every other rom I've tried also exhibited the same behaviour...
I can get into download mode easily using 3BC. It is not as easy to get into recovery, but it does happen every other try or so.
From recovery, if I do a reboot, it starts the phone allright. If I reboot the phone from the power menu in the phone, it restarts the phone allright.
However,
If I power down the phone, it does not power down completely. It powers down, and if I have the power cable in, it shows a battery loading animation without movement, and I am not able to power up the phone, without first going to recovery mode.
If the power cable is not in, it still acts as it is and shows the battery loading animation. Then it seems like it knows that the power cable is not in, and restarts the procedure resulting in a battery icon boot loop.
This is fixed either by going into recovery and rebooting system or by flashing a new kernel in download mode and booting from there.
Has anyone experienced something similar?
This is how it looks: http://youtu.be/TvjUUL852Us
I'm inclined to think it is a hardware problem.
I got the same issue. But it only appear if I flash cm7.2 or higher.
If my phone is powered off, only the battery icon appear (without charging or movement of the status bar).
It doesn't load up the Battery. After starting the phone the battery loading up very fast.
Maybe it's a software issue because our devices never will get an official update to ics or jb.

Hi,
my dear D4 falled down from my jacket, after it doesn't want to power on. I tried to remove the battery and boot, but it freeze on motorola dual core technology screen. I tried to boot with the wallcharger (and battery on) but after this screen the phone simple reboot and come back to motorola dual core screen. What could i do to get it back?
It has CM12 and safestrap on (perfectly work before it fall down)
After come times without battery on, i retried to attach it and connect the wallcharger. The phone, after motorola dual core screen, show a "?" inside the battery (on battery charging screen)
It looks like phisical damage
Can you load Fastboot option ? (Hold volume up, down and power button when your phone is off)

Hello!
ID: C5J8 BIOS: 2.05c
Symptom: if I shut down the tablet from Windows 10 or in Android 5.0 then I can't power on by button.
If I connect the USB cable afterwards it can be powered on random time - sometime after usb cable connect 5 minutes, sometimes more, it is very stochastic behaviour!
My question is: is it bug or feature? The reasen is settings in BIOS or what the hell, I dont understand? I have to tilt my family shut down the tablet, because they can't power on without me...
Do anybody have a good idea?
has nothing to do with windows or android for sure ... when the tab is in the S4 or S5 states the control of the tab is done by the BIOS firmware
1. do a restart/reboot from whatever OS and after that a power off and check whether is responsive now
2. do a forced power off (long press power btn until turns off) and check again
however if it did not show this behavior on your previous bios version then for sure is caused by something in the new bios (i would guess has something to do with the way the battery level is now detected, normally if your battery is below a level it will refuse to start, but if somehow the bios doesn't properly detect that...) maybe you can also try a 'load defaults' in the bios?
Have a look at this thread, it explains how the tablet determines when to turn on.
Dear wallabyman!
Thank you, it is very detailed and good post. I understand, and we can't do anything - it is a feature, but a very ugly feature from Teclast!
This time do you have any change in this operating? Could you power on by button after shut down?

It has operated in the same way with the original BIOS too!
The reason why I found the linked thread was because I am experiencing some problems too, although not as bad as you describe them.
I am able to always turn on the tablet. If it does not turn on, I am trying the following things (in no particular order):
- Make sure tablet is really off and not stuck with black screen, by holding power buton for 10-15 seconds to do a hard powerdown
- attach a USB lamp to USB-host adapter to see if it is still powered on
- let it charge for about 30 minutes with original charger and original cable before trying to turn on
- not move the USB charging cable too much, my device seems very sensitive to small changes in the USB charging connection. I have the tablet lying flat, and try to power on without touching the cable if it is charging at the same time
- set quiet boot to off in Bios to see the red AMI logo
a minor aspect:
- if the device is charging and I press the power button only once, the Bios boot screen will appear together with the battery, but will not boot until the power is pressed again and battery charge is sufficient
Sleeping:
- putting the device to sleep from Android (sikke1s ROM, not for your device) and waking up again seems to work perfectly for me now.
- with Windows I still have big issues, trying to narrow it down currently
- from the shutdown state I can always boot up within a few tries (press the button not too long or to short, try hard power off even if it appears to be off and again)
In order to simplify stuff I will write it in steps as it happened
1) Phone turned off while listening to yt, most likely battery drain as I didn't pay attention to it and it was low already
2) Tried to turn it on after 3% charge and it started doing application optimization (Phone did this before with no issues)
3) Looked at it again in a few min and phone was turned off
4) Proper charge and turned it on which ended with constant restarts once boot animation was reached
5) Right now it's just stuck on boot animation
Things I tried so far:
1) power and volume down button for safe mode > Keeps repeating the Sony logo and doesn't do anything
2) 2 min restart > nothing happened
3) Flashing it with sony flash tool > phone is locked as bootloader is off (I can't turn it on as I need a turned on phone for that)
Any ideas on how to fix this? Phone is neither rooted, unlocked or whatever, classic factory settings.
