Can't boot or charge - Xiaomi Black Shark 3 Pro Questions & Answers

Brand new out of the box and can't boot or charge. I'm unable to get into recovery either. Anything I can do?

Try a known good cable/charger.
If no joy, return it.

While this is not normal behavior, here are some things you can try. First, power-cycle the device by holding the power button for 20 seconds, 5 times. Attempt to start the phone by holding down the power button and the volume-down button at the same time. This will start recovery mode where you can perform a factory reset. If this does not solve your problem, please follow these steps:
1) Let your phone rest for 12 hours (do not charge);
2) Charge with the official charger and cable for 6 hours;
3) After 6 hours, disconnect then reconnect your phone to the charger. A low battery screen should appear;
4) Do not attempt to boot. Allow it charge for 1 more hour;
5) After 1 hour, your device should be ready to boot and power-on.

[Q] Xperia S stuck on boot!

I need help please!
I tried to downgrade my phone from using this guide:
thespicygadgematics.com/2012/06/downgrade-and-install-gingerbread-and.html
with the gb rom from here:
thespicygadgematics.com/2012/07/root-xperia-s-lt26i-without-unlock.html
I was on this part:
Enable fastboot mode by press and hold the volume down button and same time connect the phone to the PC via USB cable (differ from device to device)
I did it and it started flashing but suddenly it disconnected the phone and now it always displays the logo, goes back dark and so on!
What do I do now?? Please help me
First do the forced shutdown by holding power button + vol down. Then try to charge battery again, just plug it in, and try to flash again. If you can't get it to charge battery try flashing again hoping it will last long enough to finish the process.
Thanks for the reply! I did the voldown+power, then plug it into the computer and did a software reset with seus. Now everything is working again

bricked = no sign of life under any circumstances
Try putting the phone into download mode when the battery is removed. Pull the battery and leave it out. Connect the phone to the PC via USB cable, and hold down vol+ and vol- (but not pwr). The USB cable will supply the power. Let us know if it will boot into download mode using this method.

Thanks for the reply.
I tried to put the phone in download mode when battery is removed, however there was no message/flicker either on the screen and the computer did not recognise any device. I held the vol+ and vol- buttons together for about 15 seconds.

Sounds like a true brick. The phone is getting old enough that it may not be cost effective to send it out for repair. But if you do choose to go for a repair, Mobile Tech Videos in LA has a very highly respected reputation here.
There are several ways to put the phone into download mode. You should try all of them that you can before you give up.
Recovery mode:
With the phone off (and not connected to the computer), and battery installed, hold all three buttons, vol- vol+ pwr continuously until the initial boot screen appears the second time.
Download mode:
1. With the phone off and connected to the computer via USB cable, and battery installed, hold all three buttons, vol- vol+ pwr.
2. With the phone off and battery installed, hold vol- and vol+ (but not pwr) while plugging in the USB cable.
3. With the phone off and battery installed, hold vol- (but not vol+ or pwr) while plugging in the USB cable.
4. Attempt each of the above three options with the battery removed from the phone. The computer will supply the power to the phone.
5. Use Android Debug Bridge (adb) which will only work if USB debugging has been already turned on in Developer Options, since you can't boot into the system to turn it on. With the battery installed and the phone connected to the pc via USB cable, use the command "adb reboot download".
6. Use a USB jig. With the battery installed insert the USB jig into the USB connector of the phone. Some have reported that this method works when no other method would work.
My phone switches off everytime I'm charging it

[Q] S3+Paranoid Android 5.1 bootloop - Can't access recovery

Hello
I have a Galaxy S3 that was working normally for a few weeks with one of the latest Paranoid Android 5.1 builds, Boeffla kernel and TWRP recovery. Today I powered the device down and since then I am stuck in a strange bootloop, what happens is the following:
1. The device powers on as soon as I place the battery on the device, NO power on button required (when problems started battery was at about 45%).
2. If left alone it infinitely loops the "Samsung Galaxy S3 I900" screen
3. Volume Up+Home+Power if looped twice gives me the TWRP screen but the phone instantly reboots so the menu is effectively inaccessible
4. Volume Down+Home+Power enters download mode but at this point Vol Up or Vol Down commands are non-responsive, USB connection and Odin doesn't work AND the device restarts after 3-5 seconds on that screen, so I can't flash anything at the moment (Latest USB drivers installed)
5. If steps 3 or 4 are attempted when phone is connected by USB cable to laptop then the device infinitely loops the charging battery icon but it looks like it is not charging i.e. no charging animation at this point.
6. If I connect the device to power plug WITHOUT battery and replace battery when connected, then the device does not auto-start as per point 1. Power button for 5-10 seconds throws me to battery icon and halts
7. Device to power -> no battery -> attach battery -> Vol up + home + power leads to halted battery icon
8. Device to power -> no battery -> attach battery -> Vol down + home + power leads to download mode that auto-restarts after a few seconds as per point 4
I would greatly appreciate any help at this point as I am out of ideas and out of ways to search google in a meaningful way, all info I can find does not apply as I can not access TWRP or download mode.
Thank you very much
Ok

Perhaps a messed power button? You can remove the outer plastic for trial.

the power button feels ok, obviously I have no way of confirming that but it is certainly not stuck-in, i.e. i can feel it clicking when pushing it and it doesn't remain pushed in when released. all steps mentioned in my original post were tried without the back plastic on as I needed to hot-swap the battery for some of the steps. thank you very much for your input though
Your power button is faulty, if it powers on when you insert the battery then it's shorted out.

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
