So, you flashed a ROM via cwm.
A few lines later you mention that you can't install cwm... is there something I miss????
Whatever;
Can you enter Fastboot/Flash mode manually/via PC and flash a new ROM from there using Flash Tool?
Have you unlocked your bootloader?
Have you tried following these steps?
That's pretty much everything I can think of.
I hope it's just a software brick... :fingers-crossed:

No I said I can't install a rom via recovery it gets unknown error ....
But Now I have another question how to enter mt5689 in Fastboot/Flash Mode manually via pc .....with flash tool......
plz can anyone tell how to enable usb debugging mode when phone is bricked.....
if you want to install a stock rom via odin, you dont need usb debugging to be on, just boot into odin/download mode (google to see how) and flash a stock rom, then do whatever you need.

I flashed with spflash tool and process completed successfully with no error... but after installation of rom I safely remove usb of my device ... but when I try to turn my phone on then nothing happen.. now my phone is hard bricked.... Now Plz guide me what I should do now....
I heard from someone that I can be fixed with volcano box....
Plz can anyone tell me..
Did you choose correct model and version?

Stable rom as in stock rom? or a stable custom rom?
in any case. if you have cwm or twrp you should be able to access the file on your computer, or even transfer it to an sd if the phone has it..
if its a custom rom flashable zip though you you might as well just flash it.
if its a stock rom an you cant aces recovery then you have to redownload it to your pc....

Now you can't unbrick your phone because you overwritten the preloader of your phone. Remember: when flashing with SP flash tool you mustn't flash the preloader. The preloader is the file that makes possible the flashing with SP and now that you have overwritten it or flashed the wrong one, you probably won't be able to recover it. Take it to service center.

Soft brick after adb update (bootloop)

I don't know what went wrong with the adb update, but now I can't do anything. I can just enter in recovery mode and download mode.
The phone goes in bootloop (It can just load the first booting screen where there is the Samsung s6 logo) and when I try to do the manual update from external sd or adb etc... It says that is disabled. Any tip to fix it? The device was rooted before the 5.1.1 android update.
Help me please :crying:

Yes I would say so the phone is stuck in EDL mode the screen is just black and I cannot reboot it. When it runs out of battery I can see the nubia logo. How would I put it into fastboot?

Redmi Note 7 Pro - Stuck in recovery mode

Hi,
I recently got a Note 7 pro from China as a gift and I flashed it to global rom using fastboot. But because there was an app that wasn't working anymore and people have suggested its because the phone is in unlocked mode, so I went ahead and used ADB to lock it and now it's stuck in this recovery mode 3.0. Does anybody know how to either reset the phone or bypass this? Thanks in advance.
First unlock bootloader & flash again with fastboot rom
Locking and re-unlocking the bootloader
To lock the bootloader, the device has to be clean installed in Fastboot mode. For the instructions, see this page.
Once a device has been unlocked, it can be locked and re-unlocked using the same account countless of times, anytime, on any official or custom ROM.

1. Unlocking the phone will never affect any app except Mi Find My Device or other Mi Security (that too it isn't much of an impact)
2.. Now use Mi Unlock to unlock the bootloader, since you already unlocked it would unlock immediately but will also format your phone..
3. Now never lock the bootloader while using a custom ROM
Just tried but won't work... it says that this account is not bound by this device. I think it's in a *bricked* state.
Same here. Cannot unlock. Tried fastboot install with miflashtool.
I think you sign out of mi account before locking bootloader if you have done this then you have to visit service centre, they will be able to flash as they have authorised account or else you can try extracting rom into adb folder & direct click on clear all.bat file if it works
Yes, this is the problem. My mistake was installing pixel experience. After install, the device don't boot up and goes în bootloop and I wasnt able to turn off the device. After, I boot up în fastboot and flashed fastboot stock rom. This rom relocked the bootloader but don't boot. The version of stock rom is the good one, only one from miui site for Redmi Note 7 pro available. My device don't boot and cannot install anything neither stock or custom. The recovery is now stock without the option to turn off or installing update. Maybe i will try @navi_58861170's method. Maybe it will work. În other case we must use edl method which is a little tricky. If you find another way, tell me.
Not working. Sadly.
