Boot loop problem D6503 - Xperia Z2 Q&A, Help & Troubleshooting

hello ,
Today i was trying to root my Z2 D6503
using king root then a program to replace it with supersu
after first time do that , device still give me it not rooted
so i downloaded king root again (newer version this time ) and try it again
it end that my device now stay on sony log , then reboot , and keep do that
and i try to search for solution but coudnt find
think my device have locked bootloader ( since i never unlock it )
i have android LP (5.0.2) [23.1.A.1.28]
if there anything i can do ? i could manage to go on fastboot ( after alot of time of trying )
Thanks

I got the same problem and I can't seem to find any solution.
I tried to root it with no success on the newest version of Kitkat so I tried to flash an older version of it and I got stuck in a boot loop.
while trying to flash another firmware i lost access to flashmode and Sony pc companion does't detect the phone anymore, fastboot does however work and my bootloader is locked.
also charging doess not seem to work for me anymore.
Seems like we got almost the same problem, does anyone got any solution to this?
Would be mostly appreciated!
Also the firmware I tried flashing was D6503_23.0.1.A.0.167_RU.

Hello Bonises ,

i dont know what different in this time when i success to connect to device , but i just kept try and try
Hope it work for u and u find solution

Softbrick headache

Hi in there
I have a P760 which has this stock ROM V20H.kdz, I rooted it and wanted to unlock the bootloader but failed, I found out that it has an unlock-able BL, ok fine, I flahsed CWM I thought that it would work because I had installed it on many devices with locked BL, reboot and got Security Error, connected to fastboot and flashed many uboot.img, x-loader.img, recovery.img with no success at all, I have a massive headach by now, even when the stock recovery works and I can connect to that damn LG upgrade tool, it doesnt detect my phone and shoots an error. Now what? I'm extremely tired by now, please healp with some valid uboot.img, x-loader.img, recovery.img that would work with JB V20H.kdz or any solution, when I start the phone now the LG logo is displayed and when it tries to boot the screen shows different colors/artifacts. Please provide me with some help.

When a phone is in a hard-bricked state it’s most likely that the bootloaders, which is the phones initial code to launch the phones ROM, becomes corrupted.
The only way to revive the phone is to rewrite the bootloader code.
So basically, if you can't flash a rom through twrp or odin, this service we'll rewrite the os from scratch without having any acces to phone.

help me guys

goodmorning everybody . i am sorry about my bed english also i am sorry because i am writing this post while going to university so will check it later since my phone is broken
first of all my phone is lenovo k6 power i've rooted the phone and it works fine but sadly some apps detect root so i decided to remove it by installing other costum rom called lineages i guess like that
i was sure that the rom will work so i didn t do a buck up and i i did the wipe data system and i delet everything . when i tried to install the rom it didn t work it gives me error 225 which i search through the net and i discover that i need to change something in the rom i tried but it gives me same error
in that moment the phone stucked in boot it won t shut down either go trwp or fastboot i tried to install the official rom by Qfil but i can not since the phone did not shut down i've said i will let it to the point where the phone goes down of charge and try
i let it and now in the morning i tried but the programm didn t detect the phone also when i plug the phone to the charger it doesn t work please help guys i beg you all help and i promise i will not touch it again :crying::crying::crying::crying:
Shouldnt have been that bad
If the lineage os zip gave an error it means that it didnt install. TWRP should still be there and you should be able to bolt up back into recovery. Try doing the right button combination to power up and enter into recovery. I doubt that after installing a zip and rebooting your phone broke.
brother i installed trwp i am using the one that i did on rooting and installing superuser
any idea how can i shut down the phone to install the official rom
