[Q] HTC One S - Cannot get into Bootloader

I have searched the forum but no luck on this one.
When I Press Power and Down Vol HTC One S just reboots - it does not go into Bootloader menu.
I cant take the battery out as suggested elsewhere because battery is non-removable.
Fast Boot is Off in the Power Menu.
Any suggestions ?

Go to terminal Emulator and type "su" and then "reboot download".

Thanks for this.
I'm not rooted so I cant do su in Terminal Emulator
Can I do ...
adb reboot download
from Mac instead ?
Can you explain what this does ?

Hi,
maybe you can use the ADB to get in the bootloader.
just look onto this HERE
the text there is english because i've only the german explaining and so i don' need to translate it.

EDIT: Finally got into bootloader by connecting phone to a PC with USB Debugging enabled and entering "adb reboot bootloader" in console.
Hi zobojoe, any luck with getting to the bootloader? I have HTC One S imported from Germany with T-Mobile branding and I want to get rid of that branding by flashing the stock ROM but can't get in to the bootloader same as you. What version of phone do you have?

Hey, thank's for trying to help! I've seen the thread you posted before - used it to get CWM and root but I've spent last 3 hours trying to get the stock ROM in my phone (I really hate the T-mobile branding) and nothing worked. What I did was I downloaded RUU_Ville_U_HTC_Europe_1.53.401.2_Radio_0.15.31501 S.19_10.12.31501S.06L_release_251412_signed.exe and tried to flash that using RUU. It didn't let me. So I at least got the zip file from the exe (temp method) and tried to flash that in CWM but id didn't work either (probably because it was not signed). So I tried to extract the system.img and radio.img and pack it again in a new zip and sign it myself - didn't work either. Kinda stuck now. Help from someone familiar with packing ROMs would be highly appreciated. I can't be the only one trying to debrand my phone .

Maybe the bootloader is Not unlocked?
Sent from my Sensation using XDA

Yes it it. Before I unlocked it, the RUU update ended with error 170. After unlocking it RUU update started kinda flashing something, but then ended with black screen with HTC logo and then turned into RUU fail! red warning.

Hi Andrew SM
I too have been able to adb reboot into bootloader but can't understand why power + vol down just reboots the phone and not go into bootloader as it should ?
Is it the case that it is rebooting straight into recovery mode when I do power + vol down and then just boots ? - what should I normally expect to see when I boot into recovery mode ?

I don't think it is recovery - you would se a black screen with a phone icon in the midddle of it with stock recovery.
But I was able to get to bootloader with VOL DOWN + POWER finally after unlocking bootloader via htcdev.com (bootloader screen starts showing *** TAMPERED *** on the top, but that is normal). And you have to disable Fast boot in Settings -> Power of course.
Good luck!

Boot loader
Little late to the party, but I've found the best way to get into boot loader wiht any consistency is to hold the volume down and power button for five seconds or so, then let go of the power button (while holding volume down), then tapping the power button. Boot loader should pop up
Hope this helps!

Brilliant! Worked perfectly! Thanks very much.

I cannot enter the bootloader too, so I have follow your instruction and now I can enter inside bootloader. I was wondering why this was necessary.
Anyway I just have the massage : locked and NOT the TAMPERED advice.
Anyway I will wait to unlock my one s, I wanna see if a different unlock way from htcdev cames out because I do not wannt risk that the warranty could be void. Have anyone tried this: http://forum.xda-developers.com/showthread.php?t=1578908 ?

Thanks a lot for this trick! This works immediatly!

Another easy way to get into boot loader every time is :
1. power off phone
2. hold the volume down button ( until boot menu open )
3. press power button for about 2-3 seconds then let go

How to enter HTC Mazaa's booloader menu?

I have been trying to enter Mazaa's bootloader menu but couldn't. Combination of Vol Down + Power is not working. Please help.

Camera+Vol Down+Power maybe?
And when a screen comes press back.
So it´s on my omnia 7

What mode are you trying to reach? Alternatively, what are you trying to achieve?

I am trying to enter the bootloader menu. The three color screen.

The SPL screen (it's not really a menu, at least not on any of the other HTC phones). On the HD7 it's turn off the phone, then hold down the Vol Down rocker button while turning the phone on again, and don't relelase it until you get to the SPL screen.
Incidentally, this question belongs in the Q&A forum.

Hi,
If you've got the 7720.68 (or had it before you updated to 7740/8107) firmware, your bootloader's locked and you can't access the SPL screen. if you've got 7720.500 then you just press vol down and power on, and you can access the menu.
Sorry! What did you want to do?

I am sorry I called it a menu. I am new to all this. I want to access the SPL screen to know my SPL version. If the bootloader is locked as you said, is there a way to access it? or unlock it?

Your bootloader (SPL) version should appear under Settings -> About -> More...

And how can I know MID?

Please also tell how I can enter in SPL mode if I want to use DFT tool to instal HSPL. Since I can't use Vol Down + Power On combo to enter the SPL mode what should I do?

Please reply.

Please reply people.

[Q] Can't use power button to unlock phone via HTCDev

Hi everyone,
I'm trying to flash a custom ROM, and every method requires me to unlock the bootloader via HTCdev, but I have two problems:
1) I can't boot into bootloader. When I hold power + volume-down, the phone boots into safe mode (I don't think that's normal right?). I took care of this by using adb and (adb reboot bootloader) to get into the bootloader.
2) When I'm in the bootloader, the power button (to make any selections) doesn't work. So I'm always stuck at the last screen that says "Unlock bootloader?" and I just have to select "yes" with the power button, but I simply can't!
Does anyone know how I can get the bootloader to work normally, or get my power button to work when I'm in fastboot?
Thanks in advance!

Did you get around this? I keep having the same issue!

Read the screen on your phone , you got to use volume up or volume down button to select yes or no , i think volume up is for yes and than press power

Maybe certain fastboot commands may help a little, if the power button is damaged. (Maybe take off the back cover and see if you can then push it down properly..)

And not exactly.
If I recall correctly,
vol down means moving down on the list
vol up means moving up on the list
& power button is 'select'

When you are in that screen that i showed you, what happens when you press Volume up , does it select on the scree YES unlock the bootloader (may avoid you warranty) ? If yes it select's than press power button to continue... and you will unlock you bootloader if not i don't have anything else on my mind :/

Volume up works but the power button doesnt

I'm also stuck in this screen for the past week, I got this phone for free, but now I want to root it but I'm stuck in this screen. I've tried several tools like kgs1992utility, hasoon2000's utility, even the windroid tool for htc sensation, but somehow I simply cannot get passed this screen. Is there any adb commands to replace the power button to select?
only the volume down button works, but it works in the opposite way(ex volume down actually takes you up not down) -__-

cant finish power button will not select yes
I am having the exact same problem the power button suddenly will not work on yes but does on no WIERD and very FRUSTRATING

So I had the exact same issue. I pressed the power button and volume down together and the phone rebooted back into the bootloader, this time it says *** UNLOCKED*** at the top of the screen.

[Q] Bootloader Unlocking

So i was following these steps mentioned (developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/) hoping to unlock the bootloader...
It says i need to connect the mobile to the PC in fastboot mode by connecting the phone while pressing the volume up key...
But always it seems to enter in charging mode
I wonder if it does even work, so my question....
Has anyone of you tried it, does it work or is it still a dream to unlock the bootloader in xperia c.....?

Is your bootloader already unlocked? Thats the only action you NEED a volume button once.
