After updating from cm12 to cm12.1 when I connect the power cable it starts automatically and also with the power cable is connected it doesn't power off but restarts again. The only way to powet off with the power cable connected is to press vol+ vol- and power button. Everything works fine with the power cable not connected.
Any help?
Thanks

Yes, this happens when the chargemon is broken/ not working. I had the same problem while testing CM12.1 (old build).
You can report to in CM12.1 thread.

You have to be holding the up/down vol keys when you plug it in.
Not all methods of accessing Download Mode have been added to the numerous stickied OP's about this issue, so here's a link to the procedure that works on mine:

that's the only thing that works but my comp wont recognize it and i installed the drivers and nothing also when i plug the phone into my comp the usb mounting icon doesn't pop up on the phone, so frustrated
The way I do it and it does work is two ways.
Of course make sure your drivers are installed
Turn off phone
Plug in USB cable to PC only
Hold Vol +/-
Plug in USB to phone
Wait a second and let go of Vol +/-
or
Download Terminal Emulator
Type
su
reboot download
I ran into this problem the other day as well. Instead of holding down the power button and both Volume + and -. Try just holding down the power button and Volume -. This worked for me. Every tutorial said to hold down both Volume + and -, but everytime I did it just took me to the "phone...!... computer" screen.
I tryed to downlode CM7 on my phone and i forgot to downlode ROMMANGER first then this haben
it show me (GALAXY S and CYANOGENMOD)
i can't go to the downlode mode or the recvery mode
Take out battery and sim. put the battery back. Hold volume up and down buttons and then plug usb cable while holding those 2 buttons..it ll get you into download mode.

Have you tried to Leave Odin Open. Then Plug the USB. While the USB is plugged in and Odin running press and hold volume down + Home + Power. Once the black screen comes release the Power Button.

If you have gingerbread bootloaders the button combo for download mode is simply volume up + power button. If that doesn't work then wait for the usb jig to arrive..... How did you manage to soft brick your phone, what messed the phone up?

i had my phone plugged to the charger overnight about 2 weeks back. it was charging then, however it was completely dead in the morning.
tried holding the power button, nothing on the screen
tried removing the battery (had it out for > 1hr) and then inserted the battery back and tried charging/starting , nothing on the screen
i tried the power + volumerUP + volumeDown and nothing on the screen
Tried plugging the USB to a computer and tired to put the phone in download mode , but screen was dead.
i tried replacing the battery with a new one (from ebay) and it is still dead. the battery show about 3.8V when i check the + and - terminals using a multimeter.
it was working the night before and was dead in the morning, the phone is about 22 months old and it was running the original rom (i had rooted the phone about a year back),
i am not sure if the phone is bricked, please help guys.

bricked = no sign of life under any circumstances
Try putting the phone into download mode when the battery is removed. Pull the battery and leave it out. Connect the phone to the PC via USB cable, and hold down vol+ and vol- (but not pwr). The USB cable will supply the power. Let us know if it will boot into download mode using this method.

Thanks for the reply.
I tried to put the phone in download mode when battery is removed, however there was no message/flicker either on the screen and the computer did not recognise any device. I held the vol+ and vol- buttons together for about 15 seconds.

Sounds like a true brick. The phone is getting old enough that it may not be cost effective to send it out for repair. But if you do choose to go for a repair, Mobile Tech Videos in LA has a very highly respected reputation here.
There are several ways to put the phone into download mode. You should try all of them that you can before you give up.
Recovery mode:
With the phone off (and not connected to the computer), and battery installed, hold all three buttons, vol- vol+ pwr continuously until the initial boot screen appears the second time.
Download mode:
1. With the phone off and connected to the computer via USB cable, and battery installed, hold all three buttons, vol- vol+ pwr.
2. With the phone off and battery installed, hold vol- and vol+ (but not pwr) while plugging in the USB cable.
3. With the phone off and battery installed, hold vol- (but not vol+ or pwr) while plugging in the USB cable.
4. Attempt each of the above three options with the battery removed from the phone. The computer will supply the power to the phone.
5. Use Android Debug Bridge (adb) which will only work if USB debugging has been already turned on in Developer Options, since you can't boot into the system to turn it on. With the battery installed and the phone connected to the pc via USB cable, use the command "adb reboot download".
6. Use a USB jig. With the battery installed insert the USB jig into the USB connector of the phone. Some have reported that this method works when no other method would work.
My phone switches off everytime I'm charging it
I accidentally restore a backup (of my previous Z2 which was on my sd card through TWRP) on my Z2 on Exsistenz LP ROM yesterday. After that phone wont boot. Battery was .70% at the time of death. Red blinking led is seen when connected to usb cable. POWER + VOL UP doesn't give 3 vibes as intended, in fact nothing. Neither red hard reset button(Tried pressing it for >3mins). Cannot enter flash mode or fast boot modes .(tried to flash stock ROM through flash tool-failed). Only red blinking LED appears when usb cable connected.
Wierd to found when I press hard reset button while pressing POWER button it gives 3 vibes. But nothing changed.
Tried "pressing and holding all 3 buttons (power,vol+and vol-) all at the same time till it vibrates once then let go of the power button and vol+ but keep holding vol - while plugging in the usb cable this MiGHT boot your phone into flash mode" But didn't vibrate while holding all 3 buttons.
Its out of warranty period as well.
Please help me to recover to recover??? :crying:

Something similar happened to me recently...wonder if this is a bug in a new release or something
This is what I did.
If you can't turn off phone, turn it off using the hard reset button http://sony-xperia.mobi/eng/sony-xperia-z2/231-how-to-do-a-hard-reset-and-reboot-a-sony-xperia-z2-physical-hard-reset-button-sony-xperia-z2.html
There's a really good guide on bricked z2 somewhere on xda but I can't find it anymore . What it said was useflashtools and flash and old ftf e.g. 4.4.4 or 4.4.2 and make sure to wipe apps_log and user_data in settings.
This might also help http://forum.xda-developers.com/showthread.php?t=1849170
Thanks for advice. The problem is it wont connect in flash mode. (attached usb with VOL DOWN button pressed & hold still gives only red blinking led)

If you restored another XZ2 with LOCKED BOOTLOADER's backup you probably killed your phone.
Was your bootloader unlocked?
Restoring anothers TA partition kills your device because drm keys are uniq
