Bootloop after Update / Xperia SP can't decrypt encrypted data

[Dan1eL]

Hello,

i got a problem with my new Xperia SP.

I had to encrypt my Phone because i use it as Business phone too and our Exchange Server has the rule that the Phone must be encrypted.

After the Update and the reboot the Phone isn't able to decrypt the System Data's and stucks in a Bootloop.

I'm able to fix it by myself?

Our have i send it back?

Please help me. :c

Best regards

In that case I suggest that you try to reinstall the phone software using SUS.

Then check if the encryption works.

This won't work because when it's crash looping the PC will noty recognise the phone

I had this problem too. I suspect that Sony failed to test if the update worked with encrypted storage. Bad Sony!

I tried various fixes. I couldn't find a way to recover the phone with storage intact, but I did manage to reset the phone to factory settings.

If you want to reset your phone to factory settings, download the Sony PC Companion. Select Phone / Tablet Software Update. Then click "repair my phone / tablet" and follow the instructions. This will put the latest firmware and operating system on your phone but it will wipe all of your settings and your phone will no longer be encrypted. You may have to attempt to run PC Companion a couple of times because the first time it won't have the necessary USB drivers installed.

Thank you for your post.

I had the same problem.

It is really shame for SONY 😕 , I have this device just for 2 weeks ....

Looking forward for explanation from SONY.

Had the problem after the last upgrade and I was not able to reset the phone via USB. My final resolution was to reset the phone. Therefore I did the following: in the window where to enter the encryption key tab the "keyboard" icon. Via this way you get to the settings and there you can reset the phone.

Now I just rebooted without any update and I am stuck in the loop again. That is really bad. I come from a Windows Phone Lumia 920 and after 2 month I am really wondering why people are shouting on WP - I never had so many problems with WP as I have with the XPERIA SP.

Well, this is just great....

Last night I switch off my Xperia SP as I usually do overnight, no issues at all up to the point when I go to bed. Turn it on this morning, around 8 hours later, enter my sim card pin code which is accepted. Next the decryption password screen appears and security code is accepted too, however as soon as the boot ribbon screen appears and goes through it's usual cycle for 5 to 10 seconds or so it then fades away and I am presented with the 'Enter sim card pin' screen again! Fair enough first time I think, as something may have gone wrong, until I find this is a never ending loop that is now occurring for no good reason! So, some poorly tested software 'push' update must have arrived at some point yesterday and knackard the whole android software is my next thoughts.

Not good enough really in all honesty. I've only had this handset since the start of October after over 10 years of Nokia handsets and this is the only time EVER I haven't been able to access my phone when I want it.

As suggested, I have tried a hard reset to no avail, removed the sim card from the device, also have downloaded the 'Update Service' application. Two obvious issues with the Update Service here are that the Xperia SP isn't even in the list of available devices (not sure what that is all about), and my computer cannot recognise the USB device regardless (presumable as it is encrypted). My laptop is very new also, totally up-to-date, and been connected to the phone before so there are no issues at that end. I'm pretty frustrated at this and looks like now I will have no option but to try and get a replacement handset through Amazon under the warranty.

No, I will not be paying to send off the phone for someone at Sony to diagnose and repair the issue. The phone is as new and has no damage, superficial nor otherwise any has only been out of the box for 6 weeks. Now I will loose all my settings and non-backed up files too, although fortunately I do have most of them.

All in all, not impressed here. Look forward to any response from Sony.
