i asked my cousin who worked with these problems he says you have to do some complex thing on your computer. Any other way i might send it to sony.
it keeps poping up that it cannot recognize my usb plugged in .
Try downloading and running the update service:

This should flash your phone back to default (stock) ROM I believe. It worked for me when I deleted /system
Flashtool is much better that SEUS in my opinion. Much more flexible.
When my Play would be rebooting constantly I:
1. Connected it to pc, Let it recognize my device
2. Before it would reboot again, I took the battery out.
3. Entered fastboot mode
4. Flashed new firmware

Dear All,
I bought a Mi max 2 months ago, after using it some,i decided to change my rom.
What i did:
1)Unlock phone via mi
2)Usb debugger
3)TWRP
4)Supersu rooted
Everything was fine.
I downloaded a rom and flash it in fastboot mode and BUM! total darkness.
After some research , I managed to reach my phone via MiFlash.
Mi Flash now sees my phone as a port device Qualcomm....
I downloaded a correct rom.
So what is my problem !
In EDL mode,I start flashing, 2-3 seconds it flashes than it says `can not see port`(I downloaded all drivers,disable/able driver enfor...sth)
And phone turns in NULL mode, no connection any more from pc to phone.
If i disattached/attached battery and connect again to PC in EDL mode, i can reach it for a few seconds and than again losing connection.
I need my phone to keep connected to my pc untill i will finish flashing.
It is complicated, i am not even sure if it is possible or i damaged my motherboard.
What can i do???
Thanks in advance

BOOTLOOP+no connection with pc

hi guys,
today my phone just randomly got into bootloop mode.
I didn't install any patch or tried to root.
The phone is technically brand-new.
It just loops on its way booting and there is no way to access download mode or anything.
When connected to pc it stops the loop but the pc doesn't connect to the phone when it used to do it in the past.
Whenever I disconnect my phone from the pc it gets back in the loop
