Access Bootloader - G4 Q&A, Help & Troubleshooting

Hey!
Is there any way to access the bootloader through physical buttons? I know I can access through the OS or through the recovery but I'd like to know if I can access through the physical buttons. I tried volume_up+ power_button and nothing happens
Thanks

[Q] Buttons wont work, stuck in bootloader

My friend's phone is pretty screwed. None of the buttons are working and the phone only loads into bootloader. I cant select any of the options in the bootloader because the buttons arent functioning. Is there anyway I can load it in adb and reboot it or something?
Try hooking it up to your comp. and try sdk see if it does anything.

If you have sdk installed on PC already try using adb is what he meant

Can anyone go more in-depth on how to use adb?
Having the same issue, not sure you can access ADB without having your phone in usb debugging I thought? I could be wrong. Does anyone know the commands that would be used with to reset the phone with ADB to stock default? I can't use the volume buttons there for when it ask me to press volume down to accept reset I can't do it. Its funny. I may just take the phone apart and see if dirt is in the way of the connection on the volume rocker.

Problems with power button

A few days after some problems with hardware, the power button has lost the function of waking my htc e9 +, but still maintains the reset function after 10 to 15 seconds while holding down. What could solve this problem? I think it's a software problem, I'm trying to reinstall the system, but I have trouble accessing the twrp to perform the general formatting of the system. Someone give me a light, tell me what I do not know. Google translation
Thanks
additional information
I could get into recovery if when I give the command `` adb reboot recovery``, my cell phone did not appear a black screen with a triangular symbol with a sclipping point inside, it would disappear pressing the power + volume up button.

The power button does not work to wake up the device and also does not work for bootloader selection, so I can not access recovery by default mode, and when I try to access the command line in ADB, I have that red triangle with an exclamation that could be deleted Pressing power and volume +. The main question now is, what the hell is this red triangle symbol with exclamation inside and how to eliminate it?

N7100 boot stuck

Hello.
I own a Note II which lately seemed to have some problems.
In the last few months, it used to restart somewhat spontaneously (it seemed that it rebooted when its processor or RAM were too busy, but this wasn't a rule). During one night it probably rebooted and next morning I found it stuck on the first boot screen (the one with "Samsung Galaxy Note II").
When stuck on the boot screen, if I press the power button for a few seconds, it turns off. If closed, it gets to the boot screen and gets stuck there when I press the power button. When plugged to power, it gets stuck at the screen with the empty battery that has a loading icon in the middle.
I manage however to get it into recovery mode, however, in this situation, it can't be seen by the PC, unless I put it in adb sideload mode. When stuck on the logo screen, it is seen as mtp device.
In the recovery mode screen, there are many errors (can't/failed to mount /efs, /system, /cache, /cache/recovery/last_recovery, /data, /data/log/recoverylog.txt, /cache, /cache/recovery/log, last_log, last_install.
In Windows, the PC doesn't recognize the model, however, in a virtual machine that runs Linux, it is correctly seen as Note II when in adb sideload mode, but Linux is not able to mount its storage.
I have also deleted cache, tried Samsung Kies and Note II Toolkit.
What I would like to do is recover the data on it. Do you think it is possible, and if yes, how?
Thank you.
Sounds like a failed memory chip to me.
any answer now?

No, I don't have access. What I want is to recover the files on it, if possible.
This may be a problem with the power button. if you can go into download by pressing only the menu button + volume down is because the power button is always pressed.

Sorry i think your partitions broked. I think you cant recover your data. There is has only one solution. Odin and Format....
My device too has pc cant detect my phone. I tried different cable without samsung usb drivers. Pc succesfully detected the my device.
By the way i installed lg usb driver because of someone's phone is lg and they need format.
I think there's no way to recover your data now.
BTW what recovery are you using?

Phone powered off wont reboot

My 5T decided to power off in my pocket this eve. Tried to reboot and now it won't accept my pin. Tried to boot into recovery mode (power & volume down) but only comes up with keyboard, not menu. Tried rebooting using power & volume up to get recovery mode but again comes up with keyboard. Option of forgot password gives factory reset which i want to avoid if possible. Any help please? Thank you
There are multiple ways to bypass a screen lock.
First one is using an adb command, just search on Google "how to bypass android phone with adb" and you'll find it, but for this your phone needs to have USB debugging enabled but it's already locked so it may be useless. This method will work without losing your data.
Other is using a specialised software like "DroidKit" or "DrFone by wondershare", this method will be frustrating because the software may push you to buy a subscription or something but it'll alsol work without losing your data.
