right combination of keys (bootloader/ download mode) - Huawei P10 Questions & Answers

Hello, I´m trying to boot into bootloader, I´m stucked in a loop in the screen that says my phone can´t be trusted.
If I plug it to the PC it goes to that screen, I can´t power off and if I try to plug it with vol- and then plug the USB cable it goes to the same screen.
Is there any other way to get into bootloader or download mode? I can´t get out of that screen it keeps rebooting onto it.
I already waited until the battery was dead, thinking I would be able to plug it with vol- pressed, but again goes onto the same screen.
My bootloader is unlocked.

Help bad flash

Hi all,
so i did a bad flash and my diamond doesnt boot into windows, not a problem with the Unlocker Right? turn off and turn on holding power+down volume key+ center key and back key, it boots into bootloader but it just sits there saying LOADING... and this is because the internal memory wasnt being recognize by windows before the bad flash.
do i have any other alternative??
Hi, fear not my friend. Just boot into bootloader mode by pressing power key and volume down at the same time (If you press the center button also you will trigger a hard reset.) Then plug your phone on your PC. On the bottom of the phone screen you should see that the word serial changes for USB. Then just lauch any rom upgrade(either a stock rom or a custom one). The rom upgrade utility will the upgrade your phone like it normaly does when it's not bricked. It will just be a little longer.
you have hold the power volume down and press soft reset to enter boot loader

I was trying to root the phone using the method from unlockr, and my phone rebotted and is now stuck on a black screen after the acer logo. What can I do?
I cant get into boot loader, it just shows the acer logo then goes black
edit: ive got it to go into boot loader by pressing the buttons right before the acer logo shows up..
then it shows this:
Partition checksum
splash1:chksum =8ba9da08 OK
boot:chksum=338dd7f1 !=001ed108 **fail**
recovery:chksum=2b8b7b4b !=00216b18 **fail**
system:chksum =f599c9d0 OK
========
<<FAIL>>
if I plug in the usb, my computer doesnt reconize it what shall I do?
FIXED: FOR THOSE HAVING THE SAME PROBLEM, TRY THIS
Unplug phone from PC, remove battery.
Insert battery again, press Camera + Vol+ + Power (your phone should vibrate 2 times)
Now plug USB, launch Acer Download Tool. You should see "Connected (AMSS)".
You can flash again the phone.

[Q] Bootloop help (cannot access fastboot/adb)

Note: This is a re-post from the Verizon HTC forums (http://forum.xda-developers.com/showthread.php?t=2533042)
I just rooted and S-off my HTC via rumrunner.
No flash roms install or custom recovery installed.
I wanted to see if I still had CWM from my last root (I returned to stock via http://forum.xda-developers.com/show...highlight=s-on.
So I went into the bootloader or fastboot (I don't remember) and hit recovery. This did not send me to a CWM, but it appeared to be the stock version of recovery. The process took too long (I know impatient) so I turned it off via power button + volume down.
Now I come to you in need, my phone is constantly turning off/on only displaying the green htc text, no red text, then pausing for 8 seconds, then off again to black screen. The whole process lasts 12 seconds, and this had been going on for about 10-15 min atm.
Plugging it in, my computer does not have the time to recognize it with adb, or fastboot.
I cannot use the power button + volume down to go into bootloader, and pressing the power button does nothing.
Please help me.
So here's the update.
Screen is now black, meaning the boot up/down process has stopped.
I have tried these:
A. Hold down the volume down + power button for 20+ seconds.
B. Hold down the volume up + volume down + power button for 20+ seconds and let up on the volume up button when screen goes black.
These two methods results in a single boot up to green HTC text then black screen.
I suspect the device has lost most of its power. Tried it for a third time, the device is now unresponsive and remains at black screen.
Now I plugged the usb cable connected to the power adapter.
The device enters the aforementioned continuous boot loop.
I tried method A and B, and there are no results, the boot loop continues. Now the device returns to the low or no powered state.
Now the device is connected to the computer. The same happens as if it were connected to the power adapter.
Method A and B still do not work.
Results: holding down buttons longer do nothing for me. The device seems to have lost power, but when charged, immediately the device enters the boot loop state.
Note: when doing method A and B the trials were done when screen is on and when screen is off, still no results.
Now the screen is off and not connected to anything. The problem still persists.

If I had to guess I would say your volume down is broken, else it would enter hboot
plug in the power and let it charge all day. then plug it to your pc and try to adb reboot bootloader or adb reboot recovery the instant you here the pc usb ingage.
once you get to the bootloader try and fastboot erase cache followed by fastboot reboot
after your phone boots you should be able to go back to bootloader and reinstall custom recovery

I have a few questions/concerns to this.
1. When I charge it, I can't stop the phone from the continuous boot. I'm afraid that doing this all day might hurt the phone more.
2. Currently I have been charging it via computer (still boot loop), and the computer does not recognize it at all. I think there is really not enough time because the loop duration is only a few seconds.
3. Since the phone is connected to the computer, the commands adb reboot bootloader and adb reboot recovery does not work. Error: device not found.

So what is this method supposed to accomplish?
I did this and the phone stopped the continous boot. However when I tried to go to hboot it went back into the loop. I did this twice, and I'm able to stop the loop with the bright light method, but I don't know what to do from here.
Note: when plugging phone into computer, the loop starts again.

Plugging the phone into the adapter, the phone charges, but the boot loop occurs again.

the phone should not bootup with the power cord plugged in from an off state (are you turning the phone back on ?)
turn off phone by holding power 15 seconds under a bright light
plug phone into outlet (not PC) let charge till green light comes on (not Red)
hold volume down and power for 10 seconds ( you should be in hboot)
plug phone to PC choose fastboot hit power
your now in fastboot usb
from here you reflash recovery
fastboot erase cache and reboot recovery
if your still in bootloop I'm at a loss, and seems your hboot is corrupted I think you have to return your phone to Verizon or HTC.

Well I don't know if it is truly off, I'm just assuming it is.
But yes as soon as I plug the phone into the power adapter the red led flashes on, and the htc logo appears, then the loop continues.
I'll probably take it into Verizon tomorrow and update on what happens.
Update: Welp, I gave up. I'm going to get my replacement soon and I'll be turning it into Verizon. Really it's not that bad of a loss since I just wiped the phone, only thing is I lost my screen protector and carbon skin

[Q] Unlocked Bootloader Can't Get Into Bootloader Mode

Unlocked and rooted with TWRP and SuperSU.
Ok, so I messed with framework-res.apk when I wasn't in recovery mode, and now know I should not have done this unless I was in recovery.
Phone will start to boot and begin the boot up animation but then goes blank. Adb does not recognize the device when connected to my computer, so I don't think it boots.
Problem is that when I hold volume down and power buttons together, it won't boot into fastboot mode, either.
So I can't use adb and can't get into fastboot mode. If I hold the power button down for 7 seconds, it starts to boot again but goes blank after the boot up animation begins.
Any ideas? I don't understand why I can't get into bootloader mode. I wouldn't think a system file like framework-res.apk would have anything to do with the bootloader mode.
OK, figured it out. I had to disconnect my phone from my computer and then hold all 3 buttons down - power, volume up and volume down and then release. That put me into bootloader mode.
I can now confirm that you (or at least I) should not mess with framework-res.apk even while in recovery, lol!
All I want is my custom wallpaper back, wah!
The good news is that if you can't boot into bootloader using volume down and power, you can try the 3 button reset to get into bootloader. Have to hold them all down for at least 10 seconds and you can't be connected to your computer by a USB cord.

Is there other ways to enter fastboot?

I've dropped my phone (ATRIX HD) and now it isn't turning on. The thing is when I connect to charger it shows the green light and start to boot (motorola logo appears) but then it keeps restarting forever. I've read that to solve this you enter fastboot mode and do some modifications. The problem is that I'm unable to enter fastboot when the phone is connected to the pc instead of the charger. Since the power button broke it gets even harder because I have to use a mini screwdriver to press it (and it is very hard to press the volume down at the same time also). So, is there any other way to pass the files needed for recovery or to enter fastboot mode? Thanks!
