Xiaomi Redmi Note 4 - No Recovery, No Fastboot - Only Blackscreen And Vibration

Hello,
I´m new here in this forum and I hope someone can help me with my problem!
Yesterday I wanted to update the TWRP via the official app from the Playstore. After rebooting the phone nothing worked any more - I have no chance to get to the TWRP or fastboot (Volume up/down + power). The only thing that the phone does ist vibrating in a relatively constant interval, as if it is rebooting all the time. The screen remains black.
When I connect the phone to the PC there comes a sound as if the phone is connected, but a second later it sounds as if it is disconnected again.
Thanks for your help!

Was that an unlocked device?
And also which variant do you have? Snapdragon or MTK?
Anyway, here is full guide about flashing Redmi note 4 : http://en.miui.com/thread-482304-1-1.html

I´ve already unlocked the bootloader. And it is the MTK-version.
Thanks for the Link!

Hi, does the same thing happen to me, did you find an answer?

Xiaomi Redmi 6A hard bricked, is it a lost cause?

Hi guys!
I own a Xiaomi redmi 6a (cactus).
I flashed the wrong TWRP recovery via fastboot. After I rebooted the phone, it showed the brand logo (miui) and then there was some error screen about encryption lost or something with only one button 'reset'. I clicked on this button and from that moment the phone was stuck if I remember correctly. So I tried to reboot the phone. But from that moment my screen was completely dark. It also kept rebooting itself. It doesn't start up anymore.
I tried in several ways to get into fastboot or the recovery mode, but I didn't succeeded. So I removed the battery, reconnected the cable of the battery. Pushed the power button + volume down. I feel a short vibration that indicates that the power buttons has been pressed. But I don't see anything on my screen. Not even the white MIUI logo. It also keeps rebooting. So it must be stuck I guess. The phone is not recognised when connecting it with a laptop.
The only thing that "works" is the vibration at the beginning of each reboot and the led notification that shows some light.
I tried to find the test points on the motherboard, but as far as I know that didn't work. I also read about an EDL, but sadly this is only for Qualcomm devices.
Is there still a way to fix my phone? If I could find a way to get in the fastboot mode so that I can flash the right recovery & rom....
Thanks for reading

You should try SPflash tool for Midiatek Helio chipset.

Yuhuu!

Realme x2 pro wont boot after installing new update

Hello I just installed the new ui 2.0 update for my realm x2 pro. After finishing it tried to boot but it keeps flickering in the home screen and I cant do anything.
Any idea what I can do to fix it?

yeah bro same with my realme 6 pro,
but we have another choice,
drain the battery and let the mobile turn off
after that go to the recovery mode and wipe your data.
or else we need to update the software in the recovery mode which is not arrived yet.

U dont need to wait till the battery drain. Press the power off and volume up button for about 7 sec and it should power off. when u turn it on press the power off and volume down button for 10 sec and you will boot to recovery mode. sadly I lost all my photos and data because of this.

POCO X3 NFC does not turn on anymore

I recently unlocked my bootloader and tried to install a custom ROM using twrp recovery on my Poco X3, After i installed custom ROM i tried to reboot. First it re entered to the fast boot then i went to twrp recovery again and did the whole installation process again which is wipe, format, install firmware(12.5.3.0 Global) and ROM. After that my phone does not turn on anymore not event for fastboot/recovery. No display turn on, power on vibration nothing at all.
I don't know what should I do, I've tried again to hold on the power button and I also tried to enter fast boot but as I said it doesn't work. Also when I plug my phone to charge it, nothing happens. I hope someone can help me, and sorry for my bad English.

Bootloop after failed update

Hi,
I recently tried to download official miui update. I left the phone to install update but when i came back i saw miui updating that goes to 4.99% and restarts every time. Phone was connected to the charger and temperature was high (maybe it was reason why i update has failed). I wanted to try flash stock rom but bootloader is locked. I can enter to fastboot mode but i dont have idea how can i "revive" my phone. Do you have any ideas how to fix this issue ?
