Question what is bootloader/fastboot mode "reason: bootonce-bootloader"? - Google Pixel 7 Pro

Hi, ive been having problems with my pixel 7, it seemed like no matter how i flashed it it still wouldnt work 100 percent properly. even if i used android flash tool. So today i flashed the disable-verity/verification flags and then booted into system and I turned off auto system updates and did adb reboot bootloader. It didnt reboot into the bootloader but instead shut off and showed the icon for a battery that wasnt charged. holding voldown and power did notheing immidiately so I unplugged the usb and held power and volume down. It went into the bootloader, however this time the readon was not vol down pressed but "bootonce-bootloader" instead. anyone ever see this or know what this means?

Question: Is your Pixel Carrier Locked?
It's my first post leave some comments if you find it helpful...
I was using a Linux box with a BLU oem USB c charger.. wait till the battery percentage shows 0% or 1% hold the volume down button while pressing the power button just get to the bootloader and ..
Once your able to connect it using fastboot... Either use fastboot reboot recovery or select it from the boot menu..
Download the platform tools from Google.. also the latest OTA for your device.. extract the zip to a your Desktop then toss the compressed OTA... In that folder open terminal or cmd... Run adb sideload OTA.zip..
Reboot one more time to manually enter recovery WIPE DATA nd Factory Reset..
Reboot back to bootloader fastboot reboot sideload or reenter recovery>apply OTA from adb..
Adb devices should return device and sideload... Issues the command adb sideload OTA.zip one last time... Nd your back in business... My friend

Need help with HTC sensation, i think he's bricked?

K got this HTC from a friend of me, was working before, had it rooted and fixed with custom rom
It was S-on on v1.27
k now gonna try to explain what's going wrong:
When i shut down the phone, put battery out, back in, connect to usb, i get the phone recognized by ADB (my HTC phone)
when i type adb reboot-bootloader, device responds and boots into fastboot mode
when i use vul up i get Fastboot usb on screen
from this point i can't get any further, device doesnt respond from any button action except for vol up.
Device is not recongized in windows now (windows 8 64bit) got the famous error 43
So in ADB everything is fine, but in fastboot nothing is working/responding
when i pull battery out, then put it back in, i can succesfully boot with volup en power, then i get everything running (custom rom from before) but it says safe mode
Any ideas what i can do to get this thing back on it's feet?
regards,
Robin

In bootloader(fastboot mode) no buttons will works except vol up,down and power..
If you want to flash a custom rom then
First goto bootloader
Now enter to recovery by using vol down and then power button to ok.
Place a Rom.zip in sdcard format cache/dalvik , all partition except sd and then flash rom..

problem was that none of the button's where responsive, i found the cause of this, volume buttons are damaged (the strip inside was broken)
So now i have a new problem much wurse i think
only power button works, so i did a complete reinstall with ruu, booted up fine, but always in safe mode for some strange reason,
Now after shutdown, i can't get the phone on anymore, only goes to Hboot, and there is nothing responsive, non eof the buttons work, can't use vol buttons because they are broken.
Adb is not responding either, only getting HTC Android USB device in my device list....
I think the phone is ready for trash? :S

in bootloader adb doesn't work only fastboot
so when you are in hboot screen try this command
fastboot reboot (in the hboot screen should say fastboot usb)

can't get into adb anymore so i think the phone is dead unless we repair the volume buttons right?

since you are dealing with a hardware problem then yes
but try this
boot normally(even on safe mode)
connect it to pc and type
adb reboot bootloader
it will take you directly into fastboot mode
then type fastboot reboot
see how it goes and check volume button from there(to confirm the hardware issue)
otherwise repeat the procedure but instead of fastboot reboot run the ruu.exe again

Pixel Stuck in Bootloop, ADB Unauthorized, Bootloader Unlocked

Hello, I recently came on a pixel phone to build and use lineageOS on. Upon rebuilding, I believe I performed adb sync wrong the device and damaged system. After that, my adb keys became unauthorized and I am unable to access the bootloader menu(I press power and volume, but phone boots into Bootloop). I tried the steps to get to bootloader menu, but the phone doesn't power completely off, and when I press the power button it gives me the launch screen saying press power to pause/continue boot, not allowing me to go into bootloader
My bootloop goes like this: Bootloader integrity screen(bootloader unlocked, cannot be verified) --> Google loading screen --> Android recovery. This shows 2 options with the message, "Can't load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device". The two options are to try again or data reset.
I press try again, and the same bootloop ensues, sometimes getting to lineage loading logo, but then back to the same recovery error regardless. If I press the buttons(power and vol up), to go into recovery, it just shows an android with a warning sign above it, giving a message saying "Error!" on the bottom. My adb on the computer shows as unauthorized, so I don't know how I can fix this. Google has said the warranty is expired and cannot do anything to help. Ideas to fix? Thanks for help in advance!
Use power and volume down (not up) to go into Fastboot mode. Then flash the stock images

I tried that, but whenever I press any button, the phone is never turning completely off unless it dies. Even after that, it goes to the screen showing the secure boot integrity(Press power to continue/stop boot)
How can I completely shut off the device and restart it? And if system is messed up, will that leave my bootloader intact(I'm assuming so as boot is a different partition?)

Does holding down the power button for 5-10 seconds turn it off? Or if you do that does it appear to turn off and then restart?
If that fails to turn it off, try just holding power and volume down for 5 seconds, and if the screen flashes (goes off and then on) let go of the power button but keep holding volume down and hopefully it goes into Fastboot.
That should work unless you have a dodgy power or volume button. The bootloader is completely separate to the boot partition, and the fact that it's doing anything at all suggests that it's still functioning.
Only other option I can think of is trying ADB commands when it's in recovery mode, e.g. adb reboot bootloader. However, if you have the stock recovery, that may not work.

Thank You!!! It didn't work in the bootloop, so I had to let the phone drain its battery and shut itself off, then I was able to enter the bootloader and reinstall lineage. Thanks so much!

Is ur bootloader unlocked? If so, use twrp to perform a full wipe and install from twrp as well. Of you can't access trwp, and are in a bootloop, do the same thing I did: let the phone lose all it's battery, so it's outta the loop, connect the phone to a charger, then hold power and volume down. This should get you into bootloader mode where you can then use fastboot to flash twrp.

I had the same exact issue when it switched to slot B and stopped showing up on my computer when the device was in fastboot and I had no access to recovery mode. Try powering the phone down from fastboot with the power off menu. Then turn the phone on by holding the power button down and keep it pressed (it should cycle on and off b/w fastboot and a black screen. Keep holding until you feel a short vibration after about 30s - 1 min) It should then show it in adb and fastboot on your computer.
EDIT: If the phone isn't powering on, try charging it and if that doesn't work, try hard resetting it by holding the power button down for 30s-1 min. Can't imagine a bad flash would completely cause the phone to at least not load the bootloader.

Stuck at entering fastboot mode

How can I get my Galaxy Note 20 Ultra out of stuck at 'entering fastboot mode'?
Hold down power and volume down until it reboots back to recovery. I got stuck there last week and that's what worked for me.

Is this problem solved? I cannot boot into bootloader mode, thanks!
Switch off the device. Then hold volume up and down buttons and insert the USB cable plugged to PC. You will get to download/odin mode

Download mode is different from fatboot mode, I can enter, and works ok download mode. However, fastboot does not, it gets stuck in entering fastboot mode and no fastboot command works
I got same issue here, I've tried rooting via TWRP and after data wipe and "reboot to recovery" it got stuck in same thing and doesn't move at all, if I hold power and vol down it just boots the device which i dont want since i need to flash magisk as a last step. if anyone encountered this or knows how to fix it i'd be helpful
I'm not rooted but I've had past Samsung devices that I was able to root and if I'm not mistaken Samsung phones aren't able to boot into fastboot mode because Samsung removed the ability to. You can run commands via ADB mode but I think that's about it

it gets stuck into fastboot entering if i try to do it the old fashion way .. please help
Guys, turn off the phone, press volume up and volume down together, and plug the usb cable while pressing volume up and down, and wait until the phone enter in downloading mode. This work for me.

Thanks Man. This worked.
Since we can"t enter into fastboot mode is it possible to flash boot.img with adb commands?
I m having the same problem with a21s(a217f). I can t enter download mode using key combinations and the other way launching it from recovery doesn t work, it stays stuck at,, entering fastboot mode,,
The ROM is already bricked, it says in recovery when i try to factory reset the following error:,, can t mount. /system (structure needs cleaning)
Even with,, apply up. with adb,, doesn t work, it just doesn t get detected on my computer when i checked with adb tools.
! The only thing that works is that I can access my sd card and apply a update from sd card but I don t know where to get the update file. (I ll edit if it works to flash stock rom from,, apply update from sd card,, )
Anybody got some ideas or should i burn my motherboard and replace it?
sorry for bad english
Honestly plug device into PC.
Power off device
hold all 3 side buttons. Volume up and down and power/bixby.
Should usually work.
After in fast boot you must press a button Volume button to find via odin.

I already did that, unplugged the battery, reconnected it after 1min, connected my phone to the computer and pressed all 3 side buttons, still doesn t work. I guess the download mode is deleted or something..
Volume up & down, no side key, then connect to PC. Works for me. Connect to PC first does not work for me.

It wouldn't be deleted as it's a safety protocol if the device has a bad update and freaks out.
Maybe try to person above method.
Normally I can enter download mode with any of these methods if you cannot I'd suggest trying to get the device replaced due to software malfunction

Samsung phones use a tool called Odin to flash firmware. If you're flashing custom firmware firmware you'll need to have your bootloader unlocked.
I got mine into download mode just now. It's a Galaxy A13 .. Like stated above, try to hold all three buttons down and connect to USB. I had to let go before it showed the battery charge icon. From off. If not from off try from charging. I think that's what I did just now. Plug the usb -> let it show the charging icon (from powered off!) -> hold all three buttons, let it power on, let go. DONE.
just follow this video it helped me a lot to unlock my boot loader

I Flashed My Note 20 Ultra With Recovery.img And Now Its Stuck On Orange State "Bootloader Unlocked" Warning Message!

Ok Guys So I Shouldn't Have Done This But I Used Fastboot To Flash Recovery And I think I Did It Wrong. It Said "ok" And Finished And I Rebooted Phone It Resetted And Then Stuck On The Orange State Bootloader Message. I Do The Recovery Mode And Goes Black And Nothing Is Responsive For a While, Sometimes Longer Than Others. This Happens If I Start Phone Normal Or Try Fastboot Or Download.
Because Of My Mistake I Cannot Connect To Pc Software And Im Not Sure Of What I Can Do. I Feel Like Im Not Going To Like The Answer For This But I Got To Take The Blame For This.
Btw i Have A Samsung galaxy Note 20 Ultra Sm-N986u
I think your phone is hard bricked
so you can't get fastboot using volume up+power or via adb?
rescue from manufacturer site pos or just device not being recognised?
It isn't hard bricked it's just way of Samsung trying to make life of simple people more difficult, people who paid for Samsung phones lots of money.
To sort that screen issues what you can surely do is,
Simply press volup + voldown buttons at the same time, no matter if you're on that orange screen or whatever just press those those two buttons at the same time and keep pressing them while you connect your phone to pc. you will boot into download mode. Then flash stock firmware for your phone. After stock of flashed Reboot and start your phone, go to developer options see if oem unlock option is there if it is then oem unlock it if it is not then go back to settings manually change date to year ago, then go to updates disable auto update, connect to WiFi, and press on update several times untill window shows up saying no updates, then go to developer options you should see oem unlock, unlock it.
Then boot into download mode and make sure you have working copy of recovery.
And make sure you follow instructions of whoever recovery you installed on how to boot into recovery. I have S20 plus and too had troubles with it, and the only working recovery for my phone is twrp customised. To boot into it after flashing recovery from odin auto reboot disabled I pressed voldown and power, USB cable connected, then after screen goes off I changed from voldown to volup while kept pressing power button and cable connected. Orange screen with warning showed up for 5 sec I kept pressing and it bottled to twrp and then I was able to install custom rom beyond rom and while installing in aroma I was able ti choose option to remove orange screen.
That's it.
I ran into the same error. I mistakenly loaded twrp's recovery into userdata instead of ap section. The phone was stuck at the orange screen and nothing was happening whatever i pressed. I waited till the battery to dry out and with 0% battery, i directly connected to pc and was able to get into download mode. Then i flashed stock and everything is now back to normal.
