(super) soft-bricked Z3 Compact - Xperia Z4/Z3+ Q&A, Help & Troubleshooting

My CyanogenMod 12.1 nightly build starting screwing up the screen after a week. I couldnt unlock screensaver, and if i could the screen would be very messed up and mostly unresponsive. So I re-followed the step on the Wiki with a 6 day newer nightly build.
However, when i got into fastboot this time (after `$ fastboot flash boot boot.img`, then `$ fastboot reboot`) the screen was all messed up in the recovery menu as well, and volume (or any other) buttons werent working.
So I looked around the wiki looking for how to flash with recovery, and did not find anything. Did not know about XDA developers. and not knowing anything about flashing, recovering or the alike I downloaded the recovery img, and did ran `$ fastboot flash boot cm-12.1-20151020-NIGHTLY-z3c-recovery.img`.
Thinking about it i realise this last command was retarded, i think i have broken my boot partition. I can no longer get into fastboot. Instead of red light to constant blue light now the lights flash red then green then the screen is just back lit.
is all hope lost or can i fix the boot partition without fastboot?
EDIT:
So ok i might actually have hardware problems and i'm incorrectly blaming it on software. I can get into fastboot every 5-6 times, but never managed to reboot it into recovery mode.

[Q] [fixed] bootloop after attempting encryption(5.0.2)

My base state was after running all the instructions here: http://forum.xda-developers.com/z3-compact/general/how-to-root-backup-drm-keys-t3013343
Phone had been working fine in this state.(Rooted/locked bootloader) I also have a backup of the TA partition
With the new 5.0.2 release, I upgraded via instructions/files at http://forum.xda-developers.com/z3-compact/development/stock-firmware-23-1-0-690-generic-t3056413 with the addition of flashing 2.8.3 lockeddualrecovery
Phone was working fine on first boot and rebooted(as needed) a few times fine. However I then attempted to enable encryption(via settings->security). The phone began boot looping(which I assumed was normal) however it is now 20 hours later and it is still boot looping. Occasionally(1/30 reboots) the phone will show a padlock icon that will show a circular loading icon for a couple seconds and then reboot. I can get in to fastboot mode but can't seem to do anything since my bootloader is locked. Also cannot boot into recovery via any button combination. Attaching adb for logs never sees the device.
Bootloop: No led-> sony logo(red led) -> sony logo(no led) -> sony logo(orange led) -> dim "powered by android(orange led) -> reboot
Any suggestions? I can't send it to Sony for repair as it is a UK unit and I am in the US(Not worth paying another ~$100 in shipping plus whatever the repair cost will be). Warranty is already void and I can recover the TA, so I'm willing to try anything.
[edit] can also get phone into flash mode. however trying to flash generic D5803_23.0.1.A.5.77_US.ftf still causes boot loop
[edit2] fixed, this thread can be deleted. After flashtools "finished" the first time it wasn't really done and I needed to reattach the phone in flashmode again to finish. I'm now booting to the homescreen.
I understand you're glad to fixed the bootloop.
On the other hand the issue itself isn't fixed.
I believe encryption to be very valuable and I really want it to be fixed.
Anybody else has any ideas or succes combing root & encryption?

XT1092 flashing (as in on screen flashing) recovery "no command" screen. Bricked?

XT1092 flashing (as in on screen flashing) recovery "no command" screen. Bricked?
Apparently I did something stupid. I had 5.1 which didn't OTA on its own to 6.0. So I thought it maybe had something to do with a past root i had and TWRP recovery. As solution I went and flashed a stock 5.1 rom in fastboot, which worked fine. Still no OTA though, and adb sideloading gave a status 7 error. Then I fastbooted the 6.0 stock rom, but that wouldn't boot (phone would hang in the white "unlocked bootloader" warning screen. I re-flashed 5.1 in fastboot.
Probably not a smart move, cause now I'm stuck in a bootloop to recovery mode where it's flashing the "no command" recovery screen for a fraction of a second, then black screen for 4 seconds, repeating over and over. I can trigger some orange log error by pressing VOL*UP like when you go to recovery mode, but it disappears in the bootloop. (it says qe 1/1 though, which suggests its rooted I read somewhere). So I can't do anything with it anymore. I read tons of threads here of which I found 2 with a similar problem:
http://forum.xda-developers.com/moto-x-2014/help/xt1092-flashing-command-boot-attempt-to-t3259287
http://forum.xda-developers.com/moto-x-2014/help/possibly-soft-bricked-moto-x-flashing-t3195103
It's the same problem I have now, and one of them says that "with some luck" he got into fastboot, but doesn't describe how.
Googling "flashing" related to recovery and/or "no command screen" in this context does'nt yield much result unfortunately.
For the love of god, I can't get it into fastboot mode anymore to do something/anything about it. I pressed, hold, tapped POWER and VOL*UP on countless ways, and it does a "deeper" reboot with appearance of the white unlocked bootloader screen, but it just keeps bootlooping.
How can I fix this? Did I brick it by fastboot flashing 6.0 and then fastboot flashing 5.1? Is it hard bricked and useless?
What do I have to flash when I manage to get in fastboot?
OK, I fixed it. Discovered it when the battery was drained. When the phone is OFF, holding POWER+VOL*UP+VOL*DOWN for 5 seconds and then releasing triggers the fastboot. Problem then is that you can't flash anything cause the battery is nerely depleted. So I let it charge in the bootloop for a bit and I found out I can hard reboot and get into fastboot by holding POWER+VOL*UP+VOL*DOWN for about 10 seconds and then releasing it. It probably turns off and then triggers the fastboot/bootloader mode.
Afraid of bricking it with OTA as I've downgraded to 5.1 from a (non-functioning) 6.0 I've manually flashed a 6.0 stock ROM in fastboot using this guide including mfastboot. So no sideloading or anything. Now it properly boots and I've got a stock 6.0.
Hopefully this helps someone in the future.

Boot-loop Help

Hey, sorry to bother everyone with another bootloop thread by I just can't for the life of me work out if I'm doing something wrong, or my device is more of a dud than usual.
So got the phone yesterday, did some ota updates ended up in a bootloop.
Now at this point my bootloader wasn't unlockable as I hadn't enabled it in developer settings.
By some miracle it managed to boot itself back into the OS after an hour of fiddling and i decided to enable the option in developer settings.
Now I've unlocked the boot loader and got all the flashing related fastboot commands working i've
Flashed a stock image using the miflash tool, seems to succeed but then on reb but once it's done i'm still in a boot loop!
I've been able to boot into twrp a few times (though most of the time I can't and am still in a bootloop)
Tried flashing a custom rom, but I always seem to be in a boot loop after attempting that.
Throughout the last few hours i've also managed to hit the os a couple of times but it seems very easy to accidently put it back in a bootloop.
If anyone has advice of something to try, that would be great.
(was trying stock image version 10.0.9.0, going to try and go back to stock Oreo)

Sometimes it goes to a failed to boot screen, while other times it seems to loop endlessly.

Try some custom kernel, or patched boot img
I've found in 3 Mi A2 phones (mine, gf and family member) the bootloop is actually easy to overcome pretty quickly by waiting. I got the bootloop with all of them when they updated to two updates from what they came with no bootloader unlocked or flashing.
In each case I plugged the phone in, and left it rapidly turning on and off. Make sure to watch the phone, it will possibly come up with an error screen a couple of times so just press to continue trying to boot (also a glitched screen maybe that says fastboot with no options, press the volume control and the option to continue appears again). After a minute or two the phone will get to the normal charging screen, at that point the bootloop is fixed just hold power button until it starts.
Longest I had to wait was coming up to 2m, one time less than 30s.

Yeah, A2 have A/B partition and if update is faulty and the phone ends in bootloop, after a few failed boots, it will boot from other partition.

I think something along these lines is how i managed to get into the phone the first time and enable oem unlocking.
After a lot of playing around I was able to get the phone to boot by flashing the latest Oreo image (9.6.16)
After that tried going to a pie image again from fast-boot image (10.0.8) and once again ended up in a boot loop.
Lastly I flashed a fast-boot image of the latest ota (10.0.10) and managed to boot in.
So phone is at least all working now. Thanks for everyones help. Just hope the next ota doesn't bootloop the phone again.
@NotOverHere: When the phone finally does boot up, do you find it's stable and reboots are fine after that?

Can't get into recovery

Hey all
I'm updating to May Updates using This Guide and then plan to update to June.
Problem is that I send 'adb reboot recovery' and the phone restarts, shows the start up screen, then the Google logo, then restarts without ever showing the android logo.
I can get into Fastboot mode and try to select recovery with the volume and power, but again, it boots to the google logo, then back to the unlock warning and boots to my lock screen, never going to the android logo.
Ideas?

Make sure you are using the latest adb/fastboot binaries (April, 2020). Flash the stock boot.img from the same guide. You will be unrooted but will be able to boot into System. Now read up on how to patch your own boot.img, it really is very simple. Personally I do not depend on, wait on, or use OTA's. The full image is available the first Monday of every month, and I extract/patch the boot.img from it. The whole operation including rooting takes just a few minutes. It's just one extra step. Once you get the pattern down it can be done very quickly, consistently and you're not depending on someone else's files. If you are bound and determined to use this method, you should seek out more guidance in the tutorial thread itself. Good luck. :good:

Not able to boot into recovery

I was trying to flash a new rom couple days ago and I feel I did a mistake somewhere which led to an issue and I can't manually boot into recovery (I have tried reflashing recovery) when ever I try to boot into recovery or rom does it for Android updates it gets stuck in fastboot from here I can't turn on the phone, when ever I try to turn it on, it boots back into fastboot, the only way for me to actually get back into my device is by using a pc with fastboot boot recovery.img. It usually updates the rom and I can get back to my device from here. I've tried a couple of things but I'm not able to go to recovery without my pc. Suggest me some fixes that could possibly fix the phone
Thanks in advance
