Fastboot Mode problem

i just bought redmi note 4 , and long story short, the fastboot mode (volume down+power) will only display for about 10 seconds and then it will reboots itself into charging mode. doesn't matter if i use the key, or even use adb commands to get there. it will still reboot itself in short period of time.
* if I normally go into fastboot this happens too... after a few second fastboot mode disappear..
why is this happening? how to fix this?
please help

Stuck in peculiar boot loop

I tried to flash twrp and now my phone is stuck in a 5 second boot loop.
Fastboot and recovery can't be accessed at all no matter what combination I make. vol+ power, vol- power, both +- power, hold 40 secs 60secs (useless because phone reboots in 5 secs) , all tried. Every 5 seconds it just boot loops. Help me.. I have it for less than a week. Wanted to flash only because the stock rom was giving problems such as landscape and auto random reboots.
I even tried a script which said would wait in adb detect mode, that didn't work. Guess phone rebooted before my pc could detect it. Tried installing intelSOC method as suggested in another thread, the short reboot is tough to get by.
By the way, it's an umidigi china phone.
bump.. pls help!
Hi , let your battery to completely empty , press vol + and plug usb to see if phone goes into Fastboot mode if not try Vol - and plug usb .
Both didn't work. But thanks.

Xiaomi Mi Pad 1, dead. Pls help.

Guys my Mi Pad 1 was running on Remix Rom based on shield blobs. Suddenly it hanged up upon reboot it only went into FASTBOOT, could never boot into bootloader. I did not have the time to fix it right away, now the situation is it does not boot up even to the fastboot screen. Only when connected to power outlet, first red led notifications blink then the Mi Logo comes up and then it goes into fastboot, but in the fastboot mode when connected to PC it does now show up.
Looking for some advice and help on how to fix this situation.
Get new USB cord and leave on charge hold power button down like 20 30 seconds plug it in while tapping power ..
Try holding volume down when off and plung in pc ..

Xiaomi mi play - Black screen problem

My problem is with black screen Xiaomi Mi Play(M1901F9E). No fastboot, no recovery. If it is connected to charger only led flashes two times every minute. Also, when holding Power button + Volume Down/Up phone vibrate after every 10-15 seconds. I download official fastboot ROM and tried to connect the phone with XiaoMiFlash but phone is not showing. Only I can hear(on PC) a USB connection (and disconnection 1 second after) every 10-15 seconds while I'm holding Power button + Volume Down.
I tried to deattach battery to try to reset it, but nothing happens.
Does anyone know solution or where is EDL test point on this model?
If You allredy download the rom
extract the boot.img

Go to your adb fastboot file location and paste the boot.img
After you paste the boot. Img
Don't connect your phone. When you doing this next steps
Open a command to your adb fastboot

Question How to save a black brick

I tried to root my phone by magisk.
After flashing a patched boot.img, it's failed to boot into system and I got a message that "the device need factory reset". I clicked yes and everything seems ok,I can boot into system. Then I tried to flash img again. So I boot into bootloader. Unfortunately, this time I got a black screen. The phone doesn't response me anymore.
I tried the software repair in xperia companion but It cannot dected my phone when I hold on volume down and plugged in it. I also tried hold on volume up + power but nothing happened. Hold on power key also no response. The led light always black, only become red when I connect it to my pc.
What should I so now and what's my phone's status? I searched something about 9008 mode and edl but I don't know how to check whether my phone is really turn into that status, my pc cannot dect my phone.
Have the same problem, only with the 5 iii instead. Still looking for a fix.
Try to switch the phone off; then just plug it into your PC without holding the Vol- key. It has happenned a couple of times with me that the phone does not want to boot up, with attempts to get it into FLASH mode by holding the key down throwing more confusion into the mix.
I think there is a low battery protection. Make sure the phone is charged up. Keeps the device from death during a flash.
Red led mean a very low battery. Keep it plugged (not to PC but to power adapter) for 2-3 hours and then try again a force reset.
Never, never try flash or other stuff under 50% battery
Also force restart is keep pressed vol+ and power button (or vol- and power button) till you fell a vibration.
Try this after a good charge

It might require experimenting with service modes and different chargers. I had an early Xperia 1 III that bootlooped while charging after setting up the fingerprint reader. It seems that charging is disabled during booting. It has to finish or enter a service/fault mode.
my phone is having this after doing fastboot --slot=b reboot recovery (which actually I had to do fastboot --set-slot=b and then fastboot reboot recovery). the notification light blinks red. have tried vol up + power, vol down + power, and vol up + down + power for like 30 seconds and nothing

I feel sorry for you brother...such a nice device...OK let's talk what happened, the state now your device is in is called hardbrick and it had a corrupted bootloader or no boot loader, but your device is still alive, in your PC in device manager it lists as Qs USB mode with some number after it like qsusb9008...now this device can only be brought to life with the help of a blankflash file which can flash your boot loader in snapdragon service mode...actually no snapdragon can be hardbricked permanently now you need appropriate blankflash file for your device.. Please don't open the device if some repairmen suggests to do JTAG nothing is necessary all you need is blankflash file which is shared to only Sony testers groups.... Who tests ROMs before release and they hardbrick so they share those files to them.... Please don't loose hope....it takes time but certainly it can be bought back to life... And dont try any flashing utility as there is no functional boot loader on it now and nothing will work...Sony won't provide that for sure and they will say then can only solve by mother board replacement ,don't believe therm your device is perfect it only needs blankflash file as it entered into final safe mode... I ain't regular on XDA if you need any info contact me via my mail [email protected] g ma I'll .com
Have any of you tried this - https://developer.sony.com/develop/open-devices/get-started/flash-tool/download-flash-tool/
ok in my case it was the charging IC
