Bricked Z3C stuck on kernel logo - Xperia Z3 Compact Q&A, Help & Troubleshooting

I'm a bit stuck with a weird case; I have a rooted Z3C(locked bootloader) which I achieved by following this thread https://forum.xda-developers.com/z3-compact/general/how-to-root-backup-drm-keys-t3013343
It's been working fine for 1,5 year, when suddenly a week ago after the battery was low and shut the phone down, it got stuck in a bootloop while it was charging (already over 40%).
Couldn't get it to boot into recovery mode(nor it was detected by flashtool), until after a few days I was able to acces TWRP, made a backup(still got that, as well of a backup from the TA partition from 1,5 year ago). And then wiped the phone with TWRP as well. After another attempt to boot (which didnt work) it was able to get into the clockworkmod recovery(it's a surprise how that got on there), and chose "restore". There was a blue light and the screen went black. And it did so for over 5 minutes which made me(and a "techie") think it had probably crashed, so we forced shut it off(power button + VOL up, vibrate 3 times).
Since then I'm pretty much stuck with the situation from earlier but instead of being in a bootloop, it is now stuck on the kernel logo "Sony xperia". I can't make it boot in any kind of mode, I can only force shut down by power button + Vol up. It When trying to boot by using power button + vol UP it doesn't do anything; when using power button + down, it directly gets stuck at kernel logo.
At all attempts to boot there is no LED apprearing, LED only goes on for about 5 seconds when plugged into laptop or charger, and last the phone is not detectable by flashtool(or xperia companion).
Currently following this thread and waiting for the battery to drain: https://forum.xda-developers.com/showthread.php?t=1849170
But I wonder if that will do the fix...
In the meantime I'd like to know if there is anyone who might have some tips of what I can try?

Can you enter flash mode or fastboot?

nope, I can't enter either of them.. Unless there is a way to acces flashmode or fastboot mode without using the button combinations?

I've never stayed in your situation. Try turn off, wait the flashtools send the messenger with instructions to plug the phone, press vol. down button and plug in usb.
personally, i don't like end the whole battery in Sony's 2013>2015, because my fist sony, a M2A, after shutdown by low power, never turns on again... only tree reed lights - uhh, sony with jealous of xbox -, i change the battery and the bricks continued. Not healthy to sony hardware do this, i mean.
https://www.engineerthink.com/blog/2015/11/how-to-unbrick-hard-bricked-android-phone/
But if the last option, do that.

What you are discribing to do with flashtool, I already tried, it doesn't recognise the phone. I even tried "tricks" of different buttons and tempo's bu tthat doesn't help making flashtool recognise the device.
Also I was not able to make the phone completely decharge itself. This morning, after it drained the battery all night long by letting it stuck on the Sony logo, it came up with the battery empty logo when pressing power button. It is not possible for me to drain the battery even more, except if I keep pressing the power button every minute to activate the battery logo...
I tried the instructions from the link you pasted, to get it into fastboot with adb, didn't work, at the first command it already said it couldnt find the device:
C:\adb>adb reboot fastboot
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
error: device '(null)' not found

So, when You have powered off phone, hold vol- and plug it to computer does led on red than green and off?
And fastboot when phone powered off (hold vol+ and plug usb) doesn't work too yes?

@yaroszek, no when "powered off phone, hold vol- and plug it to computer" the LED goed red for a few seconds and then goes off(no green at all), and the screen will show the Sony logo.
when trying to fastboot with "phone powered off (hold vol+ and plug usb)" exactly the same happens...

(4.2.1) RAZR i suddenly bricked

Hey, folks,
I have a Motorola RAZR i with Android 4.1.2. I never did any modification inside the system, even root, 'cause I prefer to not put it on my cellphone. Suddenly, when I was searching on Google Now at night, the phone freezed. I got nervous, but, I tried to restart the system using the combination to put in full power off, with success, but, after, i couldn't turn the phone on until today (I think it happened a one month ago), stoping all the boot process on the giant Motorola logo.
I can't enter in recovery mode too, but the computer detects the phone when I put it on.
Is there somebody who know how to fix it?
Have you tried turning the phone on using power + vol down? As soon as it vibrates let go of power and keep holding vol down until it enters fastboot.
If it doesn't turn on, have you tried plugging in a charger while holding vol down?
If you can access fastboot you can do a factory reset.

Xperia Z... freeze and brick?

Hey there,
So today I was using my Xperia Z aaaand bam, phone "died".
Battery was at that time 70%, phone was a little bit hot, but in scale of 1 to 10 it was like 6. I had not problems previously with it (besides broken screen that got replaced 3 weeks ago). I was playing a game then suddenly it got closed and my screen got shifted. Like Animation of horizontal menu stucked while going to vertical. I pressed power button many times, I've keept holding it for a short time, long time... nothing. Phone did not respond at all. After 10 minutes it went black. No idea if it went "sleep" or so since power button do not work again.
I tried to reset it with Power + Volume down, Power + Volume up and again, nothing.
I've tried factory reset with Sony Companion but no luck either. Phone is NOT detected by that program.
However, when I plug the phone to PC I hear sound that some device has been found. Phone is presented now as QHSUSB_DLOAD in device manager. I've heard that not a good sign...
When I plug it to PC or Charger nothing happens so I have no idea if phone is getting charged or not.
What even more confusing, when I press power button - nothing, phone is COLD. But when I press Power + Volume down after a while it starts to get warm, after a long time of repeating this really warm.
Any ideas what could I do?
Thanks!

You phone has locked or unlocked bootloader? If unlocked, give a try to enter Fastboot mode and flash any custom ROM

Can you phone enter flashmode ? Does any LED indicator shows up when holding Volume +/- whilst connecting cable in PC (USB)?

Flashing red light but it still boots when power and volume down held

I relocked bootloader, updated to .253, then unlocked bootloader. Right after that, I installed a rootable kernel, booted into TWRP, installed DRM restore, SuperSU 2.74, and the new Nexus launcher. It booted fine, and I set up everything to what I had before. I then decided to restart to access TWRP to reflash the Nexus launcher as it didn't show up. After the phone shut down, it began blinking red light. I tried to force shut it down, but it didn't do anything. I tried to get to fastboot and flashmode, but the blinking red light was prevalent. However, the Sony logo showed up if I mash down on volume down and power. So I doubt that my phone is dead and only accessible through QHSUSB_DLOAD. But it's pissing me off.
Any help? Thanks in advance!
Oh, and it was 40%.
Entire situation of physical input:
1) Plug in USB=Red LED
2) Power+Vol Up=Force shut down with 3 vibrations after turned on by Power+Vol Down
3) Power+Vol Down=Turns on to Sony and Xperia screen, then shuts down
4) Power=Vibrates once, turns off
I have the same issue, Could you fix it?

My Nokia 7 Plus does not boot at all or stuck on Android One logo

My phone suddenly restarted and stuck on Android One logo and not booting further. I've turned the phone off and started after few seconds and it was still stuck on Android one logo. Then I've tried to get into recovery mode by pressing Vol Up + Power but it was not working. Also it's not responding to the charger. No battery sign and nothing. It does not respond to power button many times. I've also tried to get into fastboot mode (Vol down + Power) and even it was not working. Please help!
It's not rooted and didn't try to flash/install custom ROM.

Take phone to discharge batttery and automatically turn off. Plug in to charger for few minutes and press and hold volume up,volume down and power for 2/3 minutes. He should be turn off and then you can go in to recovery.
Suffering the same problem.
I'm having the same problem. Exactly what you said. I didn't root my device or even attempt to do anything. I bought Nokia because they were purely stock and delivered some quality mobile phones. I've got only this phone as my daily driver. So tell me if you have got the issue fixed and how much did it cost and how long it took. It's been stuck with that 'android one' logo and a small message that reads 'Download mode' on top. I've tried everything. And what I'm worried about is, my phone's out of warranty and I'm a student. I hope you got it fixed for some reasonable cost. Please reply to me ASAP.

Possible brick after updating twrp

Dear all,
I was on beyond 5.3 with twrp 3.3.1.7 and I wanted to update everything. Magisk, root etc was working fine.
I downloaded the patched twrp file from the beyond telegram chat and flashed it as image into the recovery partition.
The installation was finished in 2 seconds, but stupid me chose to power off instead of rebooting the recovery.
So I tried to enter recovery using the button combo but nothing happened and I was stuck with the samsung logo.
The current status is that my phone only shows the samsung logo.
Holding the power button for a minute doesn't do anything.
Pressing the button combo for recovery mode doesn't do anything.
Pressing the button combo for dl mode makes the phone reboot. It vibrates for a sec, then the samsung logo shows again.
If I keep pressing all 3 buttons the phone keeps on rebooting and vibrating each time, but dl mode never appears. If I let go of the power button the logo stays and again, nothing happens.
So basically I can't enter dl mode nor reboot.
Should I let it run dry and try again or just throw out of the window immediately? :crying:
I let the battery drain over night. Phone was finally off.
So when I plug it in, the Samsung Logo appears and doesn't change. It just stays like that forever until the battery drains.
Pressing the power button doesn't do anything, no matter how long. It doesn't reboot nor does the logo disappear.
Pressing vol+, bixby and power again does nothing.
Vol-, bixby and power makes the phone reboot. The screen turns black, the phone vibrates shortly, the logo reappears. If I keep pressing the buttons the phone reboots again, and again, and again, mever reaching download mode.
If I let go of the power button and keep pressing vol- and bixby the phone stays black and won't even show the logo. Nothing happens. If I let go of either of the two buttons the logo appears again.
It won't boot, won't go into recovery or go into dl mode.
I'm doing all this while it's plugged into the usb port of my pc, and it doesn't get recognized. Samsung 300k tool doesn't recognize it either.
Now I know the meaning of "bricked" lmao.
Does anyone know how to possibly fix this?
Pressing only the power button for a minute literally does nothing. Like hell, how is that even possible?
You can try this to go to download mode:
Vol down + bixby + usb cable connect to PC
It's advisable to charge battery first before flashing firmware.

I tried that for like a thousand times already but now it chose to magically work somehow.
I think I peed myself a little when that ugly turquoise screen appeared and I screamed from sheer happyness.
THANK you!!!
The problem that doesn't stop giving lmao.
Got into DL mode, got odin to start, but after like 10 seconds my phone dies and odin fails.
Now I cant get into DL mode, but rather only the "an error occurred while updating the device software. use the emergency recovery function in the smart switch pc software."
Could it be the battery that simply dies?

Yes most probably a discharged battery. Hopefully you can go to DL mode again after charging your phone.
hello,
I've and S10e and because an important app to me I need to go back to android 9 where it works.
I've read a lot info about downgrade, but no one says ROOT/UNBRICK.
Can someone inform if there is a way of downgrade without ROOT (maintaining the warranty).
thanks in advance
P.S.: Maybe too naive question, sorry for that
