My z3 doesn't turn on unless I press the yellow button near sim is it a software issu

[khanjunaid]

I had to change my phone's speaker in a local repair shop,after that the problem is persisting,power button is also functinal but not perfect. Is it a hardware issue???
I have an unlocked bootloader with RSXW 3, I tried factory reset in twrp & installing other rom, but haven't tried flashing a Ftf.
Please tell me how should i proceed???.:crying::crying:

Flash the firmware which RSXW 3 based firmware(official) via Flashtool, and don't wipe data.

@maple_mak
Thank u for your reply.
Are u sure there is a difference between twrp flashing & flashing via flashtool???(any partition that twrp can't access that can lead to getting stuck.
I don't wanna loose my root & recovery it can get really troublesome trying to root again with this problem.
Also there is a constant green led while connecting phone to pc in flashmode (& even after disconnecting) & pc shows device not recognized

You can download the app pre-rooted firmware at General thread and use TWRP to flash it.
TWRP is for flashing rom and mods. Flashtool is for flash firmware, flash kernel and unlock bootloader.
