Your bootloader was unlocked before you flashed the specific ROM?

Then do a fresh installation through the flashtool. flash a official firmware and do the same procedure from the beginning.

Oh, dude flashtool just need your device driver and you have to press back button untill you connect your phone on your pc and it also shown on flashtool which is included in procedure of flashing through flashtool and one thing PC not need to recognized your device because flashtool is the only one method to recover bricked phone. that's it .. if you got confused then please search on google you will find the solution.

Dear bjchettri
I do appreciate all your efforts
I have to explain the situation just to make things more clear because it looks like you misunderstand me
when I connect my phone (in all modes "Bootloader, Fastboot, normal, recovery..etc) nothing happens on my pc
even in device manager (i'm using Microsoft windows) the system doesn't show any item for a new attached device or an item for an defined attached driver (which used to appear all modes)
the flashtool needs the system to find an attached device to communicate with (usually the attached device name looks like "android phone", SE android or something this (depends on ur phone brand, model)
now since my system doesn't find any device when I connect my mobile then the flashtool won't be able to communicate with my device (even if i tried to boot my device in all modes "bootloader, fastboot, normal, recovery) by holding specific buttons (menu or volumn down or back buttons)
and if you read my question you will see that i was asking if anyone knows any way to connect my phone using testpoints or something like this because i though maybe I can let my pc to recognize my phone using the testpoints method.
I'm not sure but if i could make my phone recognized by the pc then i will have like 10 ways to find the problem and fix it.

Hi yazanallahham
I have the same issue, could not find any solution yet, wondering if you have fixed your fone ?

I think you flashed the boot.img instead of just booting it. have you tried doing the button thing to get into recovery
powerdown(pull out battery)
press and hold volume- and power untill you see the lg logo, then release and press and hold volume- and power, then chose yes and yes(with volume+, volume - and the power button) and you should be in twrp

Yeah tried the button combo. But instead of twrp or factory reset it gives boot certification error. Secure boot verify.

same thing what did you do to fix this??

can't do neither of that, if i try download mode the phone shows the same error and turns off. The PC recognizes the phone as "Qualcomm HS-USB QDLoader 9008(COM5). The screen on the phone however is turned off.

Yeah I know...I will send it in tomorrow, but I doubt they will repair it for free because I messed with it and they will probably see I did something I shouldn't do to the phone. What should I say when I turn it in? Probably best if I say I tried to update it and something went wrong?

yep i unlocked it. More ideas?

Flash doomlords kernel via fastboot....then reboot to system....if it will not boot successfully then push a ROM zip by adb push and flash it....one more thing just check whether your phone is connecting to PC via fastboot or flashmode.
.
The best way to check is by flashtool...open flashtool software on PC and then connect your phone via fastboot/flashmode and see the status at PC flashtool....if its connecting then flash stock ftf and if not then 1st install drivers..

There was a red light while charging for an hour or so but after a while it disappeared and now im left with dead phone. I don't even know how it happened, i was on cmw recovery and i formatted something, after i restarted my phone it started being like this. I heard that it's possible to repair boot by software called S1tool but i can't find any information about doing this on xperia s.

As far as I know, it is not possible to wipe partition from CWM (if You selected from one of the options from menu) which would lead to hard brick.
Let us start with basics. Can You tell Me which kernel You flashed to get CWM? Also, is there any vibration when You press and hold power button and volume up key together?

Can You give Me link of the kernel You used, just to see if it has any problems. Also, for how long did You hold the combination? You need to hold it for at least 10 to 15 seconds.

Huh, that kernel should have worked. I asked for the combination duration since many people make mistakes there. Since we are clear of that, did You try the rubber band trick from here? That trick sometimes takes more than a day to work.

Yep i did that and i tried many different ways to make it work.. no luck. i got annoyed and i sent it to the repairs today...

Zuk Z2 boot problem

Hallo everybody,
I have a question for you, I have a Zuk Z2 (not the pro version) I received this morning the notification for the update to ZUI 2.0.069 and, since I have unlocked bootloader and root, the official update failed, so I downloaded the update .zip file and I installed it from the recovery (TWRP).
The installation went fine but then after the reboot the phone is not turning on anymore.
I guess the phone is not completely off because the white LED is on but when I try to turn it on nothing happen, and if I press the power button for long time I see a black screen with the ZUK logo in the middle but only for a second and then the screen return black.
Also the device is not recognized by the computer.
Do you have any idea what went rong? do you know how to fiy it?
Thank you very much!

So basically what I did was enter in fastboot mode and from there, using adb comand, I unlocked again the bootloader (I already ulnocked it before but the last update locked it again) and then I was able to reboot the phone succesfully.
During the soft brick of my device I was able to enter the recovery (pressing volume up + volume down + power button for almost two minutes) but in the recovery I was not able to wipe and flash a new room, so what really helped me was a tip from a guy in the zukfans.eu forum for enter fastboot directly using the phone buttons.
To do that you have first to completely turn off your phone (from the recovery for example) and then you have to press the buttons volume up and volume down at the same time and NOT the power button, at this point you connect the usb cable from the computer and your phone will enter fastboot mode.
Once in fastboot mode you can use adb comands for recover your phone.
I hope my explanation was clear and if you need I can send you the link to the dicussion at zukfans.eu.

The problem is that when the flash-in phone automatically disconnected and I have uploaded all the files you need.

When you select "install the update package," the message "system will now install update.zip root directory of the system partition in first ..."

I do not understand what you meant when you say " The problem is that ......... file you need"
It appears that when you boot your phone went to stock recovery mode instead of normal mode. If you can not boot it to normal you might need to flash the firmware.
