Just got an s10 from someone. Trying to get into download mode but can’t doing it from keys and when I do it from recovery it says BL recovery locked by key. It will not go to download mode at all. Any ideas on how to get around it?
Will it boot into recovery for a data factory reset? That may fix it.
Already tried. Nothing will work. Even the plug in cable while holding buttons. Adb just restarts

keep holding the buttons and make it reboot as many times as needed. Well, like 10 times might be excessive, but shy of that isnt. Ive had many galaxy phones that were being a little a-hole about letting you boot to bootloader. But being forceful with continuing to force it to boot eventually got every problematic phone ive ever had into DL mode.
if you can adb into the phone, use "adb reboot bootloader" and it should automagically go to DL mode, if it doesnt, hold vol down and do that command again. It might take several times to get there, but youll get there. Im not aware of any way to lock someone out of the phones bootloader
Shut the phone off. Plug in type c connector while holding volume up, bixby and power, then plug in usb cable to pc.
I’ve done all the usb tricks also still nothing. Here is the recovery screen. Reboot to boot loader doesn’t work also

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.

well have you held the phone under a bright light and held just the power down for 15 seconds and let go when the phone go's off ?

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.

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

sorry to hear that mate!!!
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.
Hello, my young brother just bootlooped his new phone, he tried to root the device.
He was following this tutorial - https://forum.xda-developers.com/huawei-p9lite/how-to/guide-unlock-bootloader-twrp-root-t3405701
Unlocking bootloader went fine, then installing TWRP went (probably) fine, then the phone needed another factory reset. And since that moment, there is just "Your device has been unlocked..." and we can't do anything. Going to recovery is impossible. The battery is above 50% so waiting for it to go down on its own will take over a week.
We have a backup made with HiSuite.
I'm not really into huawei, so I've not a single clue what to do. Please, help us guys. Thanks in advance.

I'm not any good at such things, really. I don't want to brick the phone, that's why i'm asking you for help. And your help didn't enlight anything, really. So sorry for my ignorance, but I would be greatful if you could explain it in easier way. Thanks in advance.

Turn of your phone than HOLD Volume Down button than connect to usb than yout phone reboot into fastboot
That's what I try to do. Fastboot doesn't load when i hold volume down + power. I can't turn the device off because it just continously starts over and over again. The phone starts normally when battery goes down completely, system loads but then phone goes off due to lack of battery.

Sent me a massage after you going to Fastboot
I can't enter fastboot, it doesn't start. It just restarts and i see the screen "phone has been unlocked and can't be trusted, phone is booting..." something like that.
you cant enter fastboot, if you have not... do you even know, what you need to do, to enter fastboot? there is more than two thing to do, so, does you realy know what need to do ? call all thngs you need to do, to enter fastboot please.
got similar problems, because i instaled wrong custom recovery.
there are 2 sugestions, got in fastboot, im sure, its working if do it properly and instal proper recovery, for your model. second, use dc phoenis here
ps. why this post are in p9 not p9 lite forum?!
Well, I plug the device to PC using usb cable and when it's bootlooping I hold volume down and power button. That's how i was entering fastboot before. Now it doesn't work.
I've got stock recovery.
hold power button ~30 sec, force restart. even then nothing? well, if fastboot not working, then its gone. Ofcorse, there need to be a way, how you put on board files to work software, but im sure, thease things have only huawei.
The phone is just bootlooping, nothing else. If the battery goes down and i plug it to its charger I'm able to boot normally into the system. But once i try to turn it off it bootloops again.

I can't turn it off. It automatically turns itself on and catches bootloop. I just wrote that fastboot doesn't load at all
So my xperia sp (c5302) has booted into a bootloop after rooting with kingroot. I upgraded it to 4.3 and im not sure what to do because the sony companion wont recognize the phone when it is rebooting over and over again. I need help
To stop the boot looping, you can simply unplug the battery, it requires opening the phone though.
You can then boot in fastboot mode by plugging usb cable while holding volume-up key, and flash the partitions.

But the phone has that small "RESET" button which allows you to deal with such situations, doesn't it ?

Indeed it does, but I wasn't sure that triggering fastboot would work when warmbooting.
I gave i a try and it works. So the way to fastboot from bootloop is now:
1 - plug usb cable
2 - Hold volume up + reset button until leds turn blue
(if phone is in a boot loop, it might actually work by just pushing volume up during the boot)
So, I recently updated magisk on my phone and as usual to update my phone restarts, but this time it didn't boot up.
I think its in bootloop because when i connect it to my pc with a usb cable it goes on and off also, i cannot access to TWRP.
Can you get to bootloader (fastboot)?
If so you can restore a stock boot image and start over, or try to boot to TWRP with fastboot boot twrp.img and restore the boot image from there and then flash the installer (rename the .apk to .zip as per the new v22+ installation instructions).
I am unable to go into the bootloader or maybe im just doing it the wrong way do you mind guiding me? :/
or maybe i don't have the drivers..
my phone just connects and disconnects, so im not so sure i can go into the bootloader and launch a comand.
Can you shutdown your phone?
i don't think, because it's always turning on and off because the usb sound is going off and on in my pc so i dont really know
You need to use a button combo to get to bootloader or recovery (since you can't boot to Android). A quick web search gives this:

Exactly like what happen to my device as well
Nope, it does not let me go into the bootloader. Not even with the button combo.
Do you have twrp installed on your phone by any chance? Also a stock boot.img?
First you need to calm down I know how frustrating seeing your device on bootloop and can't even shutdown it ...
i do not have twrp, but i can download a stock boot.img
would you like me to guide you how to fix it i don't have anything to do?
Yes, thank you.
Your device is going on bootloop right now and keep vibrating right?
it's not vibrating. but it probably is in bootloop
lol mine is vibrating while on bootloop okay enough chitchat let's start
vibration is actually good indication for the next process
prepare ADB and USB cable
Now press Power Button and VOL UP at the same time wait for vibration let go Power Button keep holding VOL up for at least 3secs then let go
it's still not vibrating
now press VOL DOWN there's 3 out of 1 chance that you actually made it to fastboot mode ...
