[Q] Phone stuck in boot loop!

Hi,
This is my first time ever being on this site! I have never dealt with any rooting or modifying before. I was unlocking a moto g with Telus I got a code online and I entered it in and my phone began to get a problem. A white display shows up saying WARNING BOOTLOADER UNLOCKED! and then afterwards it shows a black screen and the process repeats again. I have tried to do the flash boot were I hold power and volume up but when I select a option it goes right back to the warning display. I am not sure what to do any help would be greatly appreciated! I have installed motorola device manager on my computer but it says its up to date and that I have the current version. Sometimes also when I plug it into the computer during the white warning display my computer recognizes the phone and tries to install some drivers but it never completes because the phone reboots.
I have tried following a youtube guide but it hasn't helped as I'm clueless on what to do.
Thanks in advance!

Unable to boot through the Mi logo

So I last time when I flash XiaoMi Mi4i I do not know why the phone seems to to bricked.
What I mean brick is :
No respond when pressing power button.
When charging no LED light.
No Recovery (Volume + and Power)
No Fastboot (Volume - and Power)
Today I manage to read a thread tha use the following instruction to save the XiaoMi Mi4i.
1. Download the Fastboot ROM.
2. Install XiaoMi Mi Flash.
3. Restart computer and disable driver signature verify.
4. Flash like normal.
The flashing process take about 720 second, The result is successful but the phone wont turn on itself.

So I try to unplug it and press the power button. No response at all then I plug into a wall powered charger the phone show me the Mi logo then turn off the screen with a red LED blinking again and again until I unplug the phone from the power sources. This happen also when I plug the phone into the computer via USB.
The good news is that I can now enter Fastboot mode. ( I assume that my device came back from brick) but no recovery menu. I then connect the phone in Fastboot mode to the computer via USB then flash the ROM again just like normal. The result success but the phone won't power on itself so I press the power button and nothing happen.
Then
I plug into a wall powered charger the phone show me the Mi logo then turn off the screen with a red LED blinking again and again until I unplug the phone from the power sources. This happen also when I plug the phone into the computer via USB.

Nope but in MIUI forum there is no one complaining about the version.

I would suggest using a MIUI 7 fastboot ROM. And a global stable one over a developer build. I ran into problems like no wifi / mobile network once, always I tried to flash the developer fastboot ROM. But once I flash a stable ROM everything was okay. Then I could easily go back to the developer ROM.
Try this,
Version: V7.2.3.0.LXIMIDA

Black screen brick

Hi guys,
Today I pull out my mix 2s from the charger and I had a black screen. When I press the power button the screen flickers, but goes black.
I have the bootloader locked and no USB debugging active.
I'm able to boot in fastboot (always with black screen)
And somehow I think I've managed to reset the phone (key combination withing the xiaomi recovery)
For a second I was able to see the xiaomi boot logo while connecting the phone to the pc, but it went black again..
I've tried the xiaomitool (but no USB debugging)
Xiaomi PC suite does not detect the phone
MI flash tool says it cannot flash with locked phone...
Do you have any other idea?

Unfortunately when I try, it says that I don't have permission to do so...
Also I've figured out that if I leave the phone alone for like 8h when I turn it on I get to see the xiaomi logo followed by a blank screen...
What could this be?

i would guess something is messed up with the system… doesn't look like the screen is bricked or something… do you get into the fastboot loader mode? press and hold power and volume down.... normaly you should see the fastboot "logo" then..

eventually you can use minimal adb and clean/format everything and reflash ah new rom

Im able to boot in fastboot and sideload, but always with a black screen
i dont have unlocked bootloader neither usb debugging active

After all it is a screen issue...
In order to empty the battery (i wanted to try to circle the battery, maybe it would help with issue) I pressed the power button straight and the phone kept rebooting (vibrating each time it reboots)
At the 5th reboot.. The screen went on. (it's like the hardware is forced to work somehow)
However the touch was not working..
After a few minutes the screen started to flicker and it completely distorted the screen image.
Now, after the 5 reboots the screen comes on but with a distorted image.
I'll send it back and ask for a refund.
Thanks.

ty for reply! I opened the back to get access to the battery, but I couldn't. It has a thin metal plate that doesn't come off, even if you remove all the screws.

Recover unbrick OP6

Hello guys,
I need your help.
Yesterday, my phone hangged and got stuck at Qualcomm Crash Dump mode.
I was just able to enter Fastboot (Power + Volume down button) but it won't wipe date, reset to factory or enter any other mode, it would just get black and do nothing, without possibility to launch the OS.
So, I used MsmDownloadTool to reformat it with the enchilada_22_H.07_180513 ROM.
The tool succeded to download the firmware to the phone but now, when I power it on, it just go directly to fastboot and whatever I do (Start, Recovery mode, Restart bootloader), it restarts directly in fastboot mode.
The problem is my device is not unlocked (I never rooted it) so I can't use the command "fastboot oem unlock"...
Due to the use of MsmDownloadTool, I know that I won't be able to recover the data but I would like to know if there is any possibility to make the phone usable again.

Try using different versions of MSM, I used the one which had OOS 5.1.5 and it successfully booted after it showed success in MSM

Thanks for your answer.
Problem is I can't use MSM as my phone is not detected anymore. It automatically boots on fastbood mode when I plug it on my computer.

I only see the "OnePlus Android Bootloader Interface" now.
I don't see the COM port "Qualcomm device" as before using MSM.

Try this:
when in fastboot mode power off the device from there and wait for 10-15 seconds once powered off then, hold the volume up button for 5-10 seconds and as you are holding it, connect your device to USB, let me know if this works or not

Ok, I will try it sunday and 'll tell you.

That manipulation works as you expected.
I'm gonna try with OOS 5.1.5 and will tell you.

that's cool! I hope it works.

Hum.. doesn't seem to work...
Tried with enchilada_22_O.09_180517 ROM but when it completes the download, it just boots with the OnePlus logo (photo) then keeps black with the cyan LED light.
Is there a way for me to diagnose what's wrong ?

you know, this usually happens with me but not on this screen, you know the screen where it says "bootloader unlocked"(if it's unlocked), there's one glitchy line on the screen and when that line appears that means something's wrong and then the phone crashes to crashdump mode but usually I get out of it by simply pressing power button but it seems like the crashdump problem is different for everyone, so coming back to your problem either the flashing is going wrong or something is off, seems like even the only solution is not working for you, I can only suggest you to try it again but if even that doesn't work then I don't think there's any solution left.
PS. I hope that you are putting your PC/Laptop in test mode before performing MSM operations.
