[SOLVED][Q][HELP][HOW TO] Unable to bypass unauthorized device

HI there.
I'm really looking forward that someone may be able to unbrick my phone or at least navigate me how to turn back bootloader, using command-line, as this would solve the whole problem.(unauthorized device + Bootloop + hardpressed volume UP button, occuring problems on the other one as well) :crying::crying:
Device, OS, Settings status: HTC VILLE (S4), Fully rooted, CM11s stable, S-OFF, SU, CID 1111111 , TWRP 2.8.1.0 hboot 2.16, ADB: xxxxxxxxxxx unauthorized device :highfive:
Actual status: After i recovered clean copy of my CM11 from TWRP (was trying some custom roms, which i didn't fully met my expectations), i decided for the first time to use Titanium Backup Pro and restore all user and system apps, settings and data which i perfomred earlier, what found out not to be the smartest move. Either way, after approx 24h my phone went down, restarted itself, unfortunatelly only as far as Bootloop
Everything would be just fine if i could just get back into bootloader. Additional problem i mentioned before is my volume button. It works but not 100%, after my phone felt down on it and vol up is hard pressed and sometimes it jams. This leads us to another (minor? :crying problem that appeared during normal use of device. Namely due to this hardpressed VOL UP button sometimes i couldn't even turn off the screen with power button (which is perefecly working if )
Concluding i`ve stuck on Bootloop. Whenever trying to turn on the bootloader with multiple combinations of pressing vol + power button, phone just restarts again. (i did that many times before without any problems) . However i'm able to turn it off sometimes
My main problem for now is with unauthorized device under ADB so i can`t neither start recovery nor bootloader using command-prompt line.
Is there any chance to bypass this unauthorized status in ADB? or should i look after new handset ? Hope that someone will be able to help . I'm willing to give away my endless gratitude full support and even reasonable amount of gold stash
XDA masters, HTC ONE S lovers and supproters, Anyone capable PLEASE HELP

It turned out everything was fine, I was unable to start bootloader because of hardware malfunction, and being more specific, hard-pressed Vol Up Button was sending signals and because of that The combination of Vol Down Button + Power brought no results. Once I lifted gently Vol Up Button with thin sharp tool, i was able to start bootloader Hope, this information will save some stress in the future. I wasn't fully aware of, thinking that if Vol Down Button was perfectly fine bit hardpressed Vol UP button shouldn't occur malfunctioning of the other button

[tips & tricks][emergency button combinations]

My First Post Thread On This Sub-Forum. So Please be Lenient.
A Couple of weeks ago I switched my primary device from Asus Zenfone 2 to Oneplus One 64gb.
A while before that... One of my friends who also owned a One got stuck on the boot logo after flashing an incompatible kernel. As the phone did not have a removable battery.. He had no idea how to go back into TWRP.
I figured that A few (maybe more) of the users would have the same kind of doubts for this device. And hence for them... I've made this simple guide.
SCENARIO 1:
•Phone Freezes,
•goes into SoD (Sleep of Death) ,or
• (practically anything that happens when booted into android but rendering most controls useless),or
• Phone Accidentally booted into fastboot mode without a PC nearby.
Fix it:
These can be easily fixed by forcing a REBOOT on the device.
How:
Press and hold the POWER BUTTON only for about 8-10s.
This will cause a reboot.
This method will work anywhere and everywhere on a one. This can be used to force a reboot in any situation.
SCENARIO 2:
•Phone stuck on boot logo /boot animation after incompatible ROM/Kernel/mod etc flash.
•When causing a Simple reboot won't help. And we need to boot into recovery or fastboot mode.
For this we need to first force a shutdown and then a normal reboot to either recovery or fastboot.
How:
Press and hold down the POWER + VOLUME DOWN Buttons for about 8-10s. The phone will power off.
Then
•For recovery press and hold POWER + VOLUME DOWN for 2-3s
•For fastboot press and hold POWER + VOLUME UP for 2-3s.
And That's it. We've successfully learned how to simulate a battery pull on the One.
NOTE: Please remember that these button combinations are universal. This means they can be used with any ROM or any kernel or even No ROM or no kernel.....lol.
Thanks.

bricked my A9

dottech.org/189086/how-to-install-twrp-recovery-on-htc-one-a9-guide/
I was following the guide at the above link trying to install TWRP on my A9. I had already successfully unlocked the bootloader through the HTCDev website. When I attempted to install TWRP , it failed due to S-ON error. Now it is stuck on the initial boot-up screen that says HTC, has a white background, and says powered by android at the bottom. Additionally, now that screen displays "This build is for development purposes only. Do not distribute outside of HTC without HTC's written permission. Failure to comply may result in legal action." in red letters. I have tried every combination of button pushes that I can think of in an attempt to power it down or restart it. It is stuck on that screen and will not respond. At this point I am just waiting for the battery to die.
Has anyone seen this before or have any suggestions. Thanks

don't understand why this guide makes you flash a boot image if you just want TWRP...
Once you're unlock, the only thing you need to do is flash TWRP from the official thread you'll find on this forum (i suggest the 2.8.8.0 version, seems to be the most stable).
You don't need to be S-OFF either...
You should still be able to boot on download mode to flash the recovery again. I've already been on that situation and I managed to get to the download mode by pressing at the same time power + volume down and holding after having restarted the phone with the power + volume up pushing and holding.

Probably because most of these 'How-to' pages are copying from each other and most of them describe not only the installation of TWRP, but also root (su). It is a simple catastrophy how many 'half cooked' and wrong descriptions are out there. I was roaming the net for 3 days now and I'm more confused than before ...
Actually I have my A9 only a week and experienced the opposite . I wanted it to be TWRP AND ROOT and found a page, that didn't mention the modified boot.img. Now I have NO root and wonder, whether I still can flash the altered boot.img (and which! Are all boot.img for unlocked A9s equal? There seems to be only one version). BTW, after flashing TWRP I also though I can enter it with Vol+ & Power but that leads in my case to also a seemingly dead phone with not even the chance to power it down, no matter how long I press that power button (have 2.8.8.0 TWRP). My only reliable way to enter TWRP is to boot into the standard bootloader and from there to reboot 'custom recovery'. Anyway ... on topic :
@TO: while the phone is showing that HTC-logo and is 'dead' for any buttons, is it still listening to the USB-port? I could reboot mine with 'fastboot' (or was it 'adb'). Something like 'fastboot reboot recovery' (or 'adb reboot recovery') helped to get me out of that dead lock. Did you try that?
P.S.: Did I mention how much I miss my removable battery (though, the A9 is beauty because of that built-in battery!)? But actually I don't understand, why that 'universal' 10+ sec. power-button press doesn't switch off the phone! Normally this trick (also on PCs) works with a kind of software independent hardware timer ... well because, to work also in the worst case of software failure. No idea what HTC did there (the A9 is my first HTC).

Try to flash a RUU related to your phone, it should fix it

You have to Press both Volume Buttons and the Powerbutton at the same time for ten Seconds. This have worked for me every Time.

Rooting Help - Virgin Mobile Galaxy J3 - Volume up button unusable :(

Heya peoples, I have a problem and am hoping for some help in a work around.
I am trying to root my J3 but my volume up button does not work. I have adb installed, and the correct drivers for my phone. I can use adb command to reboot to the bootloader and it brings me to the Odin "downloading" screen. I can then use the program to install TWRP so I can root. Everything goes fine up until this point. After TWRP is installed there is a single massive problem I am hoping there is a work around for. My volume up button does not work. I can only reboot to recover using adb once the phone boots up, and I read that if you let that happen it overwrites TWRP with the stock recovery (which is what happens when I do this). I read that you have to reboot directly from the downloading screen into recovery using Vol up and home and power. But I can't do that since my Vol up doesn't work. When I am at the download screen after installing TWRP none of the adb commands work so I can't reboot directly to recovery to access TWRP the first time. I hope this all makes since, and I hope someone has some advice because as far as I can tell I can't continue passed this point without a working volume up button.
A little more info in case it matters. When using adb command prompt I have to type ".\adb" instead of "adb" as the tutorials say. When I do ".\adb devices" my device shows up as connected. After rebooting to the bootloader using adb, typing ".\fastboot devices" shows nothing is attached, and any command I try to put in results in "waiting on devices". Checking the device management at this point does not show any unknown usb devices (one guide I read said if fastboot wasn't recognizing to check to update drivers if something was showing as unknown usb".
Basically hoping there is some way of booting directly to recovery from bootloader without having to use the vol up key combination so I can access TWRP for the first time. Any help at all is appreciated. I realize having a working volume button would take all the headache out of this but unfortunately fixing it is not an option at the moment.
Edit: I have also unlocked the bootloader using the Crom Services app from samsung, and have developer options and usb debugging enable.

Question: If I use an app to remap the buttons would that work? Wont be around a computer until tonight. Does remapping the buttons affect it at the level of being in bootloader (because if so I could just switch the up and down volume, use adb to reboot to bootloader then power/home/and remapped volume to reboot to recovery). But I feel like it wouldn't work if the app is not actually changig it but intercepting the button press and then changing it. I dunno.

Can this device even be rooted? Doesn't virgin lock their devices?
In any case if you flash twrp to the boot partition (rename it to boot.img) it'll boot directly to twrp then just use twrp to flash to the recovery partition.
Reflash the stock boot.img back to the boot partition.

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.
