Reboot loop in Xperia ZL after update to Lollipop

alejandrogs — Fri, 29 May 2015 01:51:26 GMT

The reason for my message was to make a query on the operation of Android 5.0 LOLIPOP
What happens is that the update came to my cell last Tuesday and happily settled, but since then the cell failed and refused to turn over

At first lasted a while on and off, there was only work if plugged in, and ultimately did not pass the start to turn the Xperia, he went off and returned to the logo appear, I had to force shutdown the auxiliary button the back of the cell
Not to do with my problem, I wish they could give me an answer, I have no access to it in Sony PC, so I could not do a backup or restore time cell

Connect your phone to wall charger > press and hold power & volume up for 10 seconds > let it charge for 2 or 3 hours

That doesn't help, it turns on, show XPERIA logo, turn off, and constantly repeat

@alejandrogs

In that case you will have to repair your phone with PCC

PC Companion (PCC)

Bridge (for Mac)

@alejandrogs

Your post wasn't clear, if you don't have access to a PC you can use a Mac, if you don't have either one, you can contact your local Xperia care or borrow a computer, there's no other way around it.

@alejandrogs

Run PCC on your computer > press and hold power & volume up on your phone > the phone will be off > once you are promt to connect the phone > press and hold volume up then connect the USB cable > this might take few attempts

Make sure to disable your firewall and antivirus on your computer and also make sure to charge your phone for 30 minutes

I think there was a typo earlier. When you follow the advice from uliwooly and connect it to your PC, make sure to hold volume down and not volume up. The LED should be green, not blue.

So, start the repair guide in PC Companion but do not connect your phone. When you reach the step where it asks you to turn off the phone and connect it with volume down pressed, first hold on/off and volume up for 10 seconds to force a shutdown, then hold volume down and connect it to your PC.

I took the liberty of changing your topic to describe the issue in case anyone else should encounter it.

@richard: your procedure didn't work.

This is what I did...

Try until your phone starts while plugged in with the original charger. Save ALL internal data to the SD-card.

Remove SD-card and SIM.

Plug the rebooting Sony in with the original charger. While plugged in, use the OFF button hidden under the lid at the back. Press it until the phone vibrates once and then vibrates three times.

Disconnect and follow Richard's procedure

"So, start the repair guide in PC Companion but do not connect your phone. When you reach the step where it asks you to turn off the phone and connect it with volume down pressed, first hold on/off and volume up for 10 seconds to force a shutdown, then hold volume down and connect it to your PC."

PC companion starts the repair.

Restarting didn't work afterwards, so I retried the procedure I did before (open lid while plugged in, press OFF until it vibrated three times). Then I let it rest for a minute and restarted while still connected with the original charger connected. The first time it didn't work, so retried the "OFF" procedure and the second effort, the Android rebooted. It took a while (green-blue screen with waves), made a sound at one moment and after a few minutes the initial procedure of a new initialised %, while the battery was at phone started. Then it worked, but the battery indicator was at 27%, while it was 99% full. I let it charge util it was full according to the phone, unplugged it, and shut down. That went too quick and restarting didn't work anymore. Plugged it in again and then it restarted,but the battery level was again at 25%.

So what I would conclude: the Lollipop version has a bug in it that sets the battery level at 25% for Xperia ZL, making the phone software (protecting the battery) to shut down. When the system is completely reset by PCC, it works, the second time the bug takes hold. Maybe the initial setting for the variable of the batterylevel is 25%, triggering a shutdown before the real battery level is read by the system. Suggestion for fix: set variable for batterylevel at 50% during startup, reading the real level ASAP and replace the variable with the real value.

Please contact me Richard about this fix when the Android version is corrected.
