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!

Hello, can you help me?
I am having a problem with my huawei honor 3c, I think it brick.
In brief, my phone won't start up no matter what I do, the display is completely shut off, the pc doesn't recognize the phone and it only flashes a red led for one second as soon as it's connected to the pc (without the battery), then nothing more happens.
I reinstalled the drivers and changed the usb cable but it's still not working.
it all happened when I was flashing a ROM using the sp flashtool, it was working fine but as soon as I disconnected the phone and reconnected it back to the computer, it didn't work anymore.
may someone please help?
The phone was running 6.0.1 MM stock when I got it.
It booted normally and worked for a few seconds, everything worked fine and after 10 - 15 seconds it froze and rebooted and it kept on doing that until I removed the battery.
I connected it to the PC but it wasn't detected by odin (the drivers are installed correctly). I got this message from Windows: "Unknown USB Device (Device Descriptor Request Failed)". I tried a few times and everytime this happened.
I kinda gave up but I tried to connect the phone to pc one more time and it got detected by odin like nothing has ever happened.
I flashed Lollipop but it was restarting at the end of the bootanimation.
I bought a new battery.
The "Unknown USB Device (Device Descriptor Request Failed)" problem still exists.
Somehow got detected again so I flashed TWRP and while in recovery the phone "works fine" even with the charger unplugged.
The phone is still useless tho.
Flashed back MM stock and the issue still exists.
I already ordered replacement USB port. It will come soon so i will check if the detection problem is caused by broken USB or software issues.
Also there is a small probability that my "new" battery could be dead too.
hey, bro, i have SM-N915G.
From last few days, i am facing the same issue.
All of a sudden phone keeps rebooting itself until I connect it to the power supply.
after connecting to the charger it gets booted properly.
please help me if you found any solution.

========================================
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
