Xperia XZ2 keeps restarting continuously - Sony Xperia XZ2 Questions & Answers

Hi, My Xperia XZ2 is about three years old and worked perfectly, until yesterday. WIthout any reason it restarted, and before the restart was complete, already restarted again. The only thing I can do is turn it off but when I turn it on, same thing. I used Xperia Companion from my PC to re-install software. That works, but when I remove the phone from PC, the setup-procedure starts, but does not get finished because it restarts again! Any suggestions?

[Q] No WiFi after bootloader unlock

Hey everyone,
I'm new to Sony Ericsson phones, and I just unlocked my SP's bootloader today.
What's weird is that after the bootloader unlock, WiFi refuses to turn on. Completely.
On top of that, superuser no longer seems to be working, and because of that I can no longer restore any of my apps through Helium.
I've tried flashing a new kernel, to no avail.
Any ideas?
Edit: Thread closed because no solution for a long time.

Random reboots

Hi. I hate this phone.
After three months since I got it, one day it turned off by itself and never turned on again. I sent it to customer care in the store where it came from, and they changed the battery. The moment I got home, the phone had the same problem. So I tried Sony PCC to repair it. It turned on, I installed some apps and suddendly it turned off again. I suspected it was because I deactivated bravia engine, but I'm not so sure that's the problem. Anyway, I decided to downgrade to Android 4.1 version .254 with root. Now the phone seems to be working. But sometimes it just reboots by itself. It happened once when I was scrolling Facebook, and twice when I was using Chrome. It just reboots and restars like nothing happened.
Is this a Ram problem? I can't put the latest firmware because the phone doesn't work AT ALL with it. What can I do?
Hi. Try to flash 254 fw with flashtool. It could help.
Flash the latest FTF via Flashtool
I have quite similar issue on my Xperia SP (random reboots). I have latest official rom installed via PCC.
Try switching off Stamina Mode and see if it keeps happening. It seems to work in my case.

Sony Xperia Z Bootloop At Optimizing App.. Android Is Starting

Haven't had any similar issue so far in two years. Just restarted today as I always do every other week to get into this mess. No new apps installed/updated within the past three days. Last thing I was doing was USB Tethering. No custom ROMs, running on the latest official updates, i.e. Android 5.1.1
What I have already tried is vol up&power, then vol down&power button, which did turn the phone off, but when turned on again, same thing started, and I can't get the Companion recognize it to be able to do a wipe/repair either.
Flash stock rom via flashtool
That's what I wanted to avoid.. Anyway not to lose the data? Also, where can I find version 0.9.13? I'm asking because there's this under the official Flashtool thread:
WARNING : Since Xperia Z, sony added a new set of files I called bootbundle. Those files can be bundled from 0.9.13 and can be flashed from 0.9.13 only. To all those flashing devices from Z edition to all after Z, it is highly advised to use 0.9.13 and to be sure FTF you flash contain the bootbundle set. I've been reported of hard bricks because of missing such set of files from bundles.

Sony XZ3 Android Setup crashes

Hi,
I have a big problem with my xz3. I flashed it multiple times via Newflasher but right after startup there is the fault Android Setup crashed. Wait or end. I wait and then it continues but WiFi is not found.
Before the problem occured there was a ota Android 10 setup. Also I dropped the phone accidentally. It worked a day or so and then the crashing startet.
Is there a way to wipe everything and get this phone to life again.
Thanks
( I don't know if this is the right forums. Sony forum is a bit empty)
I'm currently facing the exact same problem
The phone randomly crashes and reboots in addition to the wifi and signal drop issues you mentionned
I have searched everywhere but haven't found a solution to this
Has anyone found a solution to this ?
I tried to reflash it with xperia companion and multiple stock versions with flashtool, some checking wipe everything, still no wifi.

latest google play services update error

hey guys, post here because is the most active forum from xz2 and xz2 compact, i have both of these phones one with unlocked bootloader and the other stock, but with the lastest google play services update both phones gets into bootloop after restarting for apply the update, so im stuck on may 2020 update bacuase august 2021 update briks my both phones. Have you face this issue? do you know what to do to avoid it?
Since when do you need to reboot for a google play service update? Never heared before
Yeah, mine just started bootlooping with a play system update today, even though I already had august patches.
EDIT: it somehow fixed itself after 20/30 boot attempts
Yes, there is such a problem, gogle play updates are in Security, it is treated after a couple of reboots, but does not solve the problem sony xz2 h8266
I have same problem, trying fix this with Xperia Companion, refresh last firmware update, with reset all settings. Nothing helps, but phone start after 20\30 boot attempts like marcogiannetta said.
it happen with me either and after fix it with Companion it got same problem so , I fix it again and stop auto update but nothing stop the stupid error .. any suggestion ?
I have the same problem :-(
If it bootloops, patiently wait for 20-30 bootloops, it will eventually boot into the OS.
Then enable developer options and disable automatic system updates..
It's the only way to prevent the error so far.
Still waiting for the real solution to this problem...
The Play system update has been took down so we are now stuck on may 2020 update :/
