[Q]Tmobile Xperia Z1S Soft brick boot loop - Xperia Z1 Q&A, Help & Troubleshooting

I was trying to use xposed framework and I rebooted to install it and now my phone is stuck in a bootloop. I rooted it and it had the latest firmware. I can get into twrp. I tried using flashtool but the phone disconnects while flashtool is preparig files to be flashed. I tried repairing with sony pc companion but it says no software is available for my phone after it detects it in flash mode.

[Q] Sony Xperia ZR stuck on boot waves screen

I edited the system/etc/snd_soc_msm file to fix video recording sound quality using total commander text editor.
After reboot my phone stuck on waves screen.
I suspect that there is something wrong with rights to the file, because I renamed the original file to snd_soc_msm file.bak and created new file snd_soc_msm file with my corrections.
Is there any way to fix this problem without flashing full firmware?
Phone model is C5503, firmware version 10.4.1.B.0.101 rooted, no recovery, bootloader locked, usb debugging off
@mur466 no recovery, bootloader locked, usb debugging off : NO WAY!
unless you get access to usb debugging!
Not sure but shouldnt he be able to flash a kernel with recovery with flashtool.
And use the recovery to flash a working file again?

Managed to get it working!
I flashed stock firmware, only system partition, using flashtool. Flashtool options: flashmode, wipe only cache and exclude everything except system.
Now I have no root, but all apps and data are in place.

Looking for help with failed flash.

Hi. I have a Xperia Z1 C6903 (honami) and I tried to install Cyanogenmod on it by following this tutorial:
http://wiki.cyanogenmod.org/w/Install_CM_for_honami
What I did:
1. Unlocked bootloader, had no problems with that.
2. Went to fastboot, flashed over Boot.img, after that I couldn't get to recovery (probably because I didn't install it first)
3. Tried another Boot.img for the Free Xperia project, after that my device had a flashing red light.
4. Reflashed the previous CM Boot.img back.
3. I was told to install recovery, so I installed TWRP (Still couldn't get to recovery mode)
http://forum.xda-developers.com/xperia-z1/general/rec-twrp-2-8-6-0-z1-honami-t3074845
Now I've downloaded Flashtool along with a general FTF file, my next plan was to flash the whole thing, but I'm asking if there was something I did wrong and how to fix up this mess?
Right now by going into recovery mode I get stuck at Sony logo, tried waiting 10 minutes but nothing.
EDIT: Tried to fix it by installing Emma, reinstalled stock lollipop ROM, and TA (I think that's recovery) and nothing, can't even see sony logo anymore
EDIT2: Flashed stock ROM with Flashtool, still doesn't work...

Unable to flash TWRP Recovery to an Xperia Z1 C6906

I've been trying to do this all night and am just having no luck. I was able to downgrade to Android 4.4.4 using C6906_14.4.A.0.157_Generic_US.ftf via FlashTool, and I was able to use KingRoot to gain root and FlashTool sees this, but when I look in the system menu it tells me that the bootloader is not unlockable, as well when I attempt to run the TWRP app with root and flash the TWRP image it says FLASH FAILED. I attempt to unlock the bootloader using FlashTool only to get errors such as:
WARN - ERR_SEVERITY="MINOR";ERR_CODE="0025";ERR_DYNAMIC="Wrong parameters";
ERROR - Processing of loader.sin finished with errors.
ERROR - null
I just want to be able to flash TWRP so I can install a custom 9.0 ROM and bring a little life back to this old device. Any suggestions?
Did you solve this?
I have the same problem
