I managed to follow several tutorials.
I try to install mtk vcom drivers on 3 different laptops (Win 8 , XP , Vista)
the result is each time the same , I only have MTK USB PORT (COM X) When I connect my phone.
I read in the forum thatI must have Mediatek preloader usb vcom port to be able to flash a stock rom , however i do not have it.
When I connect flashtools ,and after cliking the download button , the phone connects and disconnects after half a second. So I am not able to flash any rom.
I tried to only donwload the preloader , by unticking every all items , but it seem the MTK usb port is too slow to load the preloader in my phone , and I have a timeout....
What can I do?
thanks for your help

Need help fixing Lenovo Vibe X3

Hello everyone! I brought a Lenovo Vibe X3 (x3a40) 3 months ago. And I updated it to MM 6.0.1 and the bootloader was unlocked and the device was rooted. TWRP was also installed. So I installed this CyanogenMod 13 from HERE.
Then I missed some stock features and decided to revert back to stock MM. And I used QFIL to flash the official stock ROM. But it turned out that QFIL suddenly stopped working and my device got stuck in EDL mode. Once I turned it off completely to flash it again, the device wouldn't boot up. In my case the device should get into EDL when I connect the USB cable and immediately hold the power key for a second. But there is no response.
Usually while booting the device vibrates but now there is no vibration nor is there anything on the display. The screen keeps completely off and it wouldn't boot into any mode, like no download/no recovery/no EDL/no bootloop, just cold.
And when I connect it to the USB all I get is the "Device not recognized" error. In device manager I get this "Unknown USB device (Device Descriptor Request Failed)".
Please note that I've tried switching the USB cable and the port as well as on a different PC and also checked with the drivers. Still the same. If someone could help me, it would be a great help.... :crying:
Further info on the device is here!

My Phone Le 1s x507 is showing only red light & phone is completely dead

Hi,
My phone suddenly gets dead/bricked & now it's showing only red light whenever I'm trying to charge the phone.
After searching in forums I goto to know that I need to flash my phone but when I connect it to pc nothing is showing & I think the phone is not gets connected ( in windows 10 ). I have installed the required USB drivers but still, it's not connecting.
1. I think I need to enable developers mode & also USB debugging but my phone is dead so I can't enable it from the phone . Is there any method to do the same from the PC? if yes it would be great if I get the details of the same.
2. Also, After phone is connected to the PC I need to Root the phone? if yes, How to do that?
I know the further procedure on how to flash mobile from SP flash tool by uploading scatter file & I want to know about the above 2 queries.
Any help will be appreciated.
Thanks.

Rog phone 3 (Tencent edition) USB -C port charging but not recognized on my laptop.(Lenovo)

Model Name: ROG 3 trncent edition( ZS661KS)
Firmware Version:WW-17.0823.2012.131
Rooted or not: yes ( was trying to root)
Frequency of Occurrence: Got<HARDBRICKED>
APP Name & APP Version (If your issue relates to the app): no app used.(magisk or anything else)
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
My rog phone 3 (tencent), which i brought about 6 months ago. I never had any issues like this.
The other day i opened my camera and suddenly the front camera was not working. I restarted the phone, did factory reset, cleared camera data, but nothing solved the issue. I thought i have to upgrade the firmware. So i downloaded the new firmware (2012.143) and connected the usb c cable with my laptop ( lenovo ideapad 320) , but it did not recognize. i tried both ports. I never had this problem before. I unlocked the bootloader, i thought it might help. I also turned on the developer option and selected FTP protocol and USB debugging. But it still didn't connect. while i was trying to enter bootloader recovery mode I accidently put the phone on EDL mode and now its bricked . The indicator light is flashing when i connect to the pc but the PC isn't recognizing the port ( i downloaded the qualcomm EDL driver on my laptop also, but the port option is not showing at all). Is it hardware problem, But the phone was charging just fine.
please help, gaming is my life
