[Q] restoring help (friend's) z3 compact d5803 factory

got it from a friend who bought it new tried to unlock the bootloader and screwed up in the middle of the process.
now it's stuck in a loop won't boot just shows Sony logo on the screen. Turns off and turns on fine, charges ok, boots into CWM recovery by pressing power and volume keys shows that it's missing some root files in the recovery.
any thoughts?

If you can boot it in download mode, just use flashify to flash factory system, and then start unlocking again

No rom, Perma-locked boot loader

Whilst installed the Omni rom my xperia shat itself, and rebooted before it could install anything.
Now as a result, if I turn on my phone, it will display the sony logo, then fade out to red, and repeat until I shut it down using the reset button.
There seems to be no option to use any of the three recoveries I installed, booting into fastboot will actually show a red light briefly however. Then it will restart again.
Flashmode seems to work, but again MY BOOTLOADER IS LOCKED. Flashtool flashes an image, says I need the according fsc script to flash my device AND it should be in debugging mode. But it says it's completed anyway.
(Which is a lie, nothing changes)
Using the Emma flasher just shows that my device is locked.
Help.

[Troublshoot]Phone is stuck on bootloop, can't access recovery mode

I'm new to this business so I might not know everything.
I wanted to install Lolipop on my xperia sp using cyanogenmod 12.1. I rooted it with towelroot, got superuser and installed Rashr to get a recovery mode program. It asked me to make a back up first, so I did. Then I went on an selected TWPR img and it flashed a partition but didn't reboot as it asked me to, I then realized I missed some steps in the installation process.
So I went on and used the backup Rashr made and it also cleaned a partition. Then I rebooted. Since then, it's stuck in bootloop, the screen flashes on and off just pure black and never reaches the logo just solid black. I tried turning it off from the back, going into recovery mode but I couldn't(I held the buttons for at least 2 min and it wouldn't work), it would just light the blue led for a little and then resume to the loop.
PC, Sony companion doesn't recognize it. It only sees it when I try to go into recovery mode(power + volume up) while it is plugged in and appears in device manager as "S1boot Fastboot", I left it for a good 10 min to install the driver, but it wouldn't.
I don't have bootloader unlocked. Right now I left it on so it could drain the battery, but it should take a long time for that to happen. Please help me!!

FIXED
After looking for other fixes, I found this guide and it worked just great.

I've a problem:
My phone is unlocked, UBL, with original 205 firmware. Sometimes it's turned off, the boot was problem: few bootloot before load the system. I installed twrp and cwm, but reinstall twrp, from twrp, and it's the problem. If I power on in flash mode, the phone exit from flash mode after 43 sec. and light is red. After 63 sec go to back to flash mode. I don't flash my phone. Help please! Sorry my english.

HELP! Bricked phone by wiping int. storage, tried ADB/EMMA/Flashtool/Sony Companion..

Hello,
While trying to unlock and root, I bricked the phone - as in its just staying at the Sony Xperia boot screen. Its still responding to Vol up+Power button to restart. The notification light turns red then green when using Vol down + attach USB.
This is what happened
1) Unlocked and Rooted the device, installed TWRP
2) Took back-up with TWRP
3) While wiping cache, system, etc. to prepare for installing custom ROM, also selected Internal Storage: and chose wipe and restart
Now phone is stuck at the Boot screen, tried the following
- Flashtool: Can install new kernel, but giving error when trying to install stock firmware
- ADB: Doesnt show up in the list with "adb Devices" command
- Sony Companion: Get stuck during software repair on the boot screen. On pressing Vol up+Power, the notification light turns on and stays blue.
- Sony EMMA: Recognises IMEI but says the phone is locked
Is there anyway to sideload TWRP or any other options of flashing stock firmware?
Many thanks in advance.

With Flashtool, Are you try to flash 4.4.4 stock firmware?

Thanks. It worked. Also realized that had to unlock again using flashtool

Xiaomi Mi A2; Cannot access recovery and bootloader

As the title says, I cannot access bootloader and recovery mode. This happened after my device was accidentally removed while flashing stock rom :crying:
Is my device hardbricked now? My device is stucked on mi logo when holding the power button. Holding power button + volume down however gives me a black screen (the screen is turned on though). Please help. I was looking for a solution for hours already but I only found solutions that would require you to either boot into recovery or access bootloader.

I'd suggest to connect phone when it is in supposed "fastboot mode" (though with black screen) to PC and type "fastboot devices" in platform-tools folder CMD. If phone is recognized, you'll be able (as obviously you have unlocked phone) to flash stock ROM or boot into TWRP to flash custom ROM, - black screen can happen with corrupt /splash partition, while bootloader may be still working.
