Please note that: This phone has never been reprogrammed/rooted/changed in any way/anything else like that. It is as stock as the day I bought it 2 years ago. I am happy to do whatever it takes to resolve the issue below.

The phone can be turned on, but will only do one of the following things:

-Black screen, old-style htc logo in centre, short vibrate, turn off, endlessly loop.

-White screen, green htc logo with "powered by android" text at bottom, short vibrate, turn off, endless loop.

Holding volume up+down together gets me to the boot screen with the following:

* Software status: Modified LOCKED S-ON *

to previous item to next item to select item


When I plug in the phone to my PC, the USB notification sound plays, but only if the menu above is showing.

Selecting any of the options reboots the phone and goes back to the menu above, with the exception of the "BOOT TO RECOVERY MODE" option. Selecting that takes me to a black screen showing the old htc logo in the centre and:

Failed to boot to recovery mode Press volume up or down to back to menu

This build is for development purposes only. Do not distribute... etc.

Pressing vol up/down at this point gives me the first mentioned menu screen, but below the * S-ON line is Security Warning *.

So, my question is:

1) Can I get my phone out of this loop and back to booting normally?

  • Almost identical happened to me last night. The only difference is that I don't get the white screen with the green logo - only the black with logo. Have you made further progress? Reading up on "phone hacking" it looks like the next step might be to try putting a RUU on a SD card and hoping that will be used to boot. I haven't yet found a RUU. The htcdev devcenter has MR1, MR2 and CRC files for my region (UK) and carrier (three aka h3g) but no RUU files.

  • I've looked into this. I cannot see how using an RUU on and SD card is possible with the phone as S-ON. Does anyone know if this can be done? I'm in the process of trying to return the handset to HTC for a repair, along with a lengthy argument, no doubt, about how their OTA update bricked my phone. Due an upgrade now anyway, but loathe the idea of discarding an otherwise perfect handset. Jul 5, 2017 at 18:01

HTC have sent me this, but as far as I can tell it's useless in our case:

(Posted as answer, not comment, because of size and formatting)

(Not sure what they've done with the numbering)

factory reset the phone in order to get out of the boot loader page, please follow the below steps

3.Press and hold the Volume Down key.

6.Release the Volume Down button when the black screen with red and blue lines of text appears.


1.Press the Volume Down button repeatedly until reboot to bootloader is highlighted, then select it with thePower button.

2.The device will display a white screen with colored text.


1.Press the Volume Down button repeatedly until BOOT TO RECOVERY MODE is highlighted, then select it with the Power button.

2.The screen will display the white HTC screen, and then turn black. After several seconds, a picture of the phone with a red triangle and exclamation mark will appear


1.Hold the Power button, while pressing and releasing the Volume up button. Note: This can be done at any time after the screen turns black. If this button combination is pressed before the image of the phone with the red triangle appears, it may take several seconds for the recovery menu to appear at the top of the screen.

2.Another black screen with red and blue text will appear.

3.Press the Volume Down button repeatedly until wipe data/factory reset is highlighted, then select it with thePower button.


1.Press the Volume Down button repeatedly until Yes – delete all user data is highlighted, then select it with thePower button.

2.Once the data wipe is complete, make sure reboot system now is selected and press the Power button.

  • Thanks for the instructions. I've gone through them, and I get: Between bullets 5. and 6. my phone goes black, then shows white HTC logo, then vibrates, then goes black again, then endlessly loops. If I then hold vol+ and vol- at the same time it exits the loop to the bootloader screen. If I select recovery mode, I get a black screen, white HTC logo, and red text stating that the phone failed to enter recovery mode. I really do wish I could just wipe it and start it again, but it's looking like it's a back to mfr repair. Which is a bit shit. Jul 6, 2017 at 18:02
