Recovery/bootloader/factory reset isnt working - Android Q&A, Help & Troubleshooting

Hello, I have a problem with my phone (Z5S Nubia Mini). When I want to turn on the phone, i have to push it for like 5s, then the phone starts (sometimes it vibrates for few times). But my problem is, that I CAN NOT get into recovery or bootloader, also i cant do factory reset via settings. When I select "recovery" (or restart or bootloader) in restart menu, the phone just turn off. When I hold VOL UP+POWER, the phone vibrates for few times, then the white screen with orange chinese text shows up, I still hold VOL UP+POWER, then it turns off again. When I tried to do factory reset via settings nothing happened, nothing was restored/uninstalled. Can you help me with this, please?
I tried to hold POWER+VOL UP+HOME and after the phone vibrates hold VOL UP+HOME only, but the phone stuck on white screen with chinese text (something like "wo")

Power button problem

Hi. I did http://forum.xda-developers.com/showthread.php?t=1586570 this to my phone and since then every time I turn it on the black screen with AP Fastboot flash failure appears and not the Motorola logo. Not that I turn off my phone that often, but it's frustrating. I have to pres Vol Up/Down + Power button and choose Normal boot everytime I want to turn on the phone. Please explain me how to unroot or I don't know, I have the phone for 5 days now. I want it to look like I've just opened the box
P.S. Already tried Factory reset, doesn't help, still the black screen when I press the power button to turn on.
P.S.2 My system version is 651.167.3370.XT910.AmericaMovil.en.01 if it matters.
Really? The link I posted is from this forum. Come on. I should be able to undo this flash I've made and really return to fabric settings.

[Q] Lenovo P780 enters Boot Loop after Factory Reset

From couple of days ago I started to get popups saying "android ____ .com" or something and every time I clicked OK the message would pop up again not letting me press anything but the OK button continuesly.. so I powered off the phone
I powered back up again and my phone wouldn't boot anymore. The screen said "Encryption Unsuccessful" and then there was a "Factory Reset" button right below - nothing happens when I clicked it
So I went on and performed a factory reset by entering recovery mode (power button + volume up + volume down) and after it didn't work I went back to recovery mode and tried "clear cache" which didn't work so I then went to factory mode (power button + volume up) and cleared data by selecting MMC or something (it was in chinese)
What happens next is, the phone enters a boot loop. It boots, shows the Lenovo logo, then turns off, then boots again, Lenovo logo, turns off, and so on. I wasn't even able to turn off the phone so I clicked that red reset button at the back
I didn't try removing the battery or SD card
How do I go from here?

Help stuck in white boot logo

Ok so i rooted my phone i format him and when he restarted it's stuck to boot logo but the lockscreen works and everyting and there is only home button and back button. How to hard reset the phone ? I think it's not bricked, there is no welcome Setup
Well, to hard reset the phone, its simply hold the power and volume up button, and may I ask how you rooted your phone, just need to make sure you did it correctly
If you can get into bootloader (I think its power+volume up) you can use the volume keys to navigate to factory reset, and press power. Rooting your 610 with windroid is the most easiest, I recommend you trying Windroid root tool. It flashes a recovery and roots
volume down and power button when phone is off.. if the phone wont turn off volume button up and power button for around 10 seconds
hope this helps
White Boot Screen with LOGO
Folks,
Similar issue, Was loading a new ROM onto HTC Desire 610 but forgot to clear Devlik Cache.
Screen now stuck in "White Boot Screen with LOGO"
Power Button with VolumeUp or VolumeDown does nothing,
Power Button with VolumeUp AND VolumeDown reboots phone but back to same screen i.e. boot sequence does not complete.
adb or fastboot can not see the device anymore.
Any suggestions / help be greatly appreciated.
[Solved]
I left the phone overnight and phone/battery died. Following morning was able to to use adb and recover phone

t870 S7 unlocked bootloader stuck in loop

sm-t870 unlocked/rooted stuck in bootloop
cannot enter recovery or download mode, or even seem to shut the tablet completely off.
any combination of buttons turns the tablet on with the message "bootloader is unlocked press power key to continue"
so holding power+volUP, must be let go to press power which seems to interrupt the button combination
power+volDOWN seems to shut the tablet off for 5 seconds but it automatically turns back on.
having plugged into laptop seems to make no difference.
help!
Hi man, have you fixed this issue? I'm having the exact same problems as yours. I updated my Magisk it just went bootloop.
Thanks!
Plug into PC then Power+Volume Up got me into recovery mode
