Boot looping after Xperia Logo - Sony Xperia XZ Questions & Answers

Okay this is a weird one.
I was in line at a store and my phone just blacked out. It didnt restart again. A few days before I had this same problem but it restarted after I held Power + Vol Up + Vol Down.
The funny thing is I had flashed TWRP onto this device. And now that is no longer booting into.
I dont care about the data, Just how to get it working again.

You are not the first with that problem. With your posting 5 of the first 6 postings in this board are about not being able to boot TWRP or ending in a boot loop. You don't even need search to find them.

[Q] Triumph stuck at moto logo, cant get into clockworkmod

Ok so today my triumph stopped responding so i restarted it (took out the battery). then rebooted. upon reboot phone shuts down and now will hang at the motorola logo for about 10 min before boots but will shut back down due to the battery being dead(but had full charge when this started). Dont know what happened. So i try to get into clockworkmod to flash backup. cant get into it. the only thing i can do is get to the recovery.img file(pressing power+volume down). Other than that nothing.
also tried to boot with power pluged in. it stayed on but would not respond to any touches or button press except the lock button.
I have cwm 5.0.2.6 installed and tickerguy's cm7.
never had this problem till today. Any help would be appreciated.
a new development has occurred. now when i try to access recovery, the phone will just vibrate without stopping.
and i believe its stuck in a boot loop but without recovery i dont know anyway to exit the loop.
Are you able to get into download mode (power off then simultaneously press power button & vol- (should show polling))

Yes i am able to get to download mode
Well after some tinkering (replacing the recovery image, assuming something corrupted it) i can now get to recovery, still takes 10 min to load it though. But i am unable to do anything in recovery because i have to press the menu button to confirm selection but the buttons wont respond. Some help would be appreciated.

HELP. Bootloop and I can't get into Recovery

Ok, so here's the thing. I flashed this theme, but it's not working and my phone won't boot. So I try to boot recovery, only I can't seem to get it. I hold down vol up + power till it reboots, then hold down vol down to get into recovery. Except it just keeps trying to boot, and doesn't load recovery. Anything I can do?
This is scaring me a lot. Need help. Thanks.
Ok, figured it out. The bootloop would go to a black screen when it froze. To get to recovery, I needed to switch to vol down 1 second before the HTC logo popped up. I used a timer to time myself properly and pulled it off.
In recovery, wiped data, restoring nandroid. Should be back up and running shortly.
I had a bootloop while on CleanRom 1.2 but since no one else reported it I just assumed that it was something I did. Probably was too.

[Q] LG G2 Soft Brick after OTA...Help?

Just took the Lollipop OTA update from stock 4.4.2. Upon completion my phone rebooted and is stuck on the LG boot logo. I tried entering download mode (holding volume up button and plugging phone into computer) but my phone doesn't enter it. Attempting to power off the phone doesn't work either, since the phone just powers off for a second and turns back on to the boot logo. I tried factory reset (power + volume down) and after proceeding with the reset the phone is still stuck on boot logo. What should I do?

You can power off if you hold power button longer. wait till logo appears, and still hold, till it gone away second time, and hold even a little longer.
Turns off but still stuck at logo when turned on

I have the same problem with the friend who posted first. There is no way on how to get to fastboot mode and when turned on it just restarts and back to logo. Hard reset is the only thing it allows me to try but no result. Any possible way to get to fastboot or download mode??? Help somebdyy

After i flashed the Lollipop firmware, it looked like the phone got stuck with LG logo but i gave it good 5 to 6 minutes and all was fine. The phone just needed to breathe a little.

Unusual bootloop - can't access recovery OR fastboot but loops on "optimzing apps"

Unusual bootloop - can't access recovery OR fastboot but loops on "optimzing apps"
I had my US version OpO 64GB working with CM12 for quite a while, rooted and bootloader unlocked with TWRP (possibly 2.8.6) installed, then some months ago I tried upgrading to CM12.1 through CM updater. This failed miserably - The phone started bootlooping on "Optimizing apps n of N" - as soon as it finished optimizing apps, the phone would reboot and start optimizing again. Booting to safe-mode (Power + VolUpDown) also fails in the same way (though optimizing fewer apps).
I tried rebooting to recovery mode holding Power + VolDown but it just gives a quick buzz (vibration motor) at the "1+" screen and reboots. The same thing happens when I try to boot to fastboot mode with Power + VolUp. So I'm completely stuck. All the guides show being able to boot either to fastboot or recovery (soft-brick) or else the screen being completely black/unresponsive (hard-brick). My phone is neither of these!
I got frustrated enough that I've let it sit on the shelf for the past 6 months, but now I'd like to fix this. All help appreciated.

Did you try clearing the cache and doing a factory reset ?

That's impossible for me to do since I can't get to launcher or recovery.
No acess to recovery?? Then better take it to service center... Atleast can u boot to fastboot mode or adb accesible then use oneplus one toolkits
---------- Post added at 11:34 AM ---------- Previous post was at 11:31 AM ----------
Install oneplus tool kit, while optimising apps it gets dectected by pc, just make it reboot mode & do reset.... Dnt worry this can be fixed, if all these seems messy then take it to service center

while things are loading, have u tried to hold vol up + power for 10 seconds or until the screen turns off and then hold vol down + power button until the oneplus logo?

Yes, just tried it. Same thing as described in my original post. When I hold power+volup the screen goes blank. I switch to power+voldown until the 1+ logo. At that point:
1. If I continue to hold the power+voldown key through the 1+ logo, the screen goes blank briefly, the phone vibrates once and reboots. If I continue to hold the power+voldown key, the vibrate&reboot cycle continues indefinitely
2. If I let go of either the power button, the voldown button, or both at or before the 1+ logo, the phone boots normally and goes to "Android is starting... Optimizing app n of 119). When the optimization finishes, the phone instantly reboots.
It's like the phone recovery is gone or inaccessible. Could this have to do with the phone tampering setting? As I said, I had this phone rooted and bootloader unlocked, working fine with CM12 for some time before trying an in-place upgrade to 12.1. That's when things went south.

Can't enter recovery mode anymore (TWRP)

Hi, I don't know what is happening, but I've been having issues with my phone. I was trying to enter recovery and pressed the button combination for fastboot instead. After that, I tried to get out of fastboot, but it kept going back to fastboot. I noticed holding up for a couple of seconds would boot me into my OS. When I try to enter recovery, the screen goes black and it restarts the phone. It will just keep going in a loop if I hold the buttons. My phone was rooted with magisk and I uninstalled to see if that would help, but it didn't.
I installed an update(I use lineage OS) out of curiosity to see if it would boot to recovery. It booted to fastboot, but after restarting and holding the recovery button combo it booted to twrp and installed the update, then restarted. Now my stupid mistake made my phone unusable. Everything is the same, except Lineage is stuck at the boot screen now. Sometimes it restarts to fastboot, but other times it stays there for possibly infinity.
I don't know what to do. All help is appreciated?
TL;DR Fixed, I think my volume down button was stuck.
Nevermind, I flashed with miflash and still had the problem, then for some reason it worked, but only once. I removed my phone from the case and found that it was booting to os. It is still kind of hard to enter the recovery. I think hitting volume up was cancelling the volume down which was stuck, or something. Now I'm pissed cause I wasted so much time on nothing
