Hope this helps. Go to their website and download the fastboot ROM of your desired phone and desired locale. There you can also find the MiPhone Flasher exe file. Run that file on your PC, connect the device with a USB cable when in Fastboot Mode, the application will detect the device, then provide the Downloaded ROM path and hit Flash. within 2-3 mins you're good to go

You're computer isn't recognizing your device? Is recovery working? Have you booted into recovery and tried the PC connection from there?
1.....Yes
2.....Yes
3.......NO
You mean ADB side load or Mount to computer? IF
that you meant NO I did not try yet.

[Completed] Help with Bricked Blu LIFE PURE XL 16GB Snapdragon, tried everything...

Hello everyone.
I'm having problem in flashing a ROM into my Blu Life Pure XL 16GB with Snapdragon (Equivalent to Redmi Note 3).
My smartphone is in the following situation: >>>It only boot into fastboot mode.<<<
I cant get into recovery mode, or EDL or anything else. Debug mode is enable and bootloader is unlocked. Tried every "button combination" and no sucess.
My PC recognize ADB interface driver, i can see my device in "fastboot devices", but if i try to type "fastboot continue" my device just get stuck on BLU logo and i must restart it. (In cant ever turn off the device)
I tried to flash a ROM through MI Flashtool, the software recognize COM port everything seems to be ok, but if i try to flash a ROM then tooks forever. The green bar gets full, more then 3 hours waiting and nothing.
I also try to enter in EDL mode to try flashing a ROM through QFIL (Qualcomm Flash Image Loader), since i can only get fastboot mode i just downloaded "fastboot EDL" that i found here on XDA however its not worked, its just get stuck in "Waiting for device...". I can list my device normally using Minimal ADB and Fastboot version 1.4.2 but no sucess with Fastboot EDL V1 and V2.
All drivers are installed and working.
Anyone else have another method?
There is another FASTBOOT EDL that works on my device?
Thanks guys.
Hi there and welcome to assist,
Unfortunately there is nothing about your question/device on XDA forum. Try a Google search first or contact the manufacturer for stock firmware and flashing instructions.
Also you can try this [GUIDE]How to reboot to EDL from fastboot
You'll have to create an account to post in the main forums if you have any other questions.
Good luck

Stuck on fastboot mode after installing custom rom

I am a POCO X2 user. Currently, I flashed the oxygen os file with TWRP recovery. But now I am stuck on fastboot menu. I tried many methods. But unable to exit from fastboot. I can only open twrp from fastboot. I search the reason behind it on the internet and I found a single way to solve this error that I have to install fastboot ROM of my device. But now I am confused that which fastboot file I should download. My device is POCO X2. But I flashed one plus os( oxygen os).
Flash stock rom on your device
