Once you unlock with HTCDev you cannot fully relock it. i.e. it will says "Relocked" instead of Locked. HTC warranty are trick but according to the agreement you'll get warranty for hardware fault not caused by unlocking Bootloader.

So did you try to contact Sunshine team as per the instructions?
yes no help from them..
You'll need to unlock your bootloader at HTCDev if Sunshine won't work.... And obviously that's not a good idea if you're sending it in.
Not sure what you can do... You're a bit stuck.
Flash an untouched firmware for your device version with external_sd method. It'll install the stock recovery.

[HELP] what to do? No Rom installed, S-ON and stock recovery

Hi guys, so the owner wiped everything from the phone and he want it back to stock now
S-ON and no custom recovery installed,
I've googled for a method to turn S-OFF but they all require a rooted ROM. what to do?
thanks in advance.
I have answered how to s-off and root Desire HD before in many threats.You can see this post.
You can also check here a newest guide.In this guide as I think you are installing a prerooted rom instead of unlocking bootloader with htc_devs unlock and flashing custom recovery to root the device.

Please help 2.11.425.7 firmware

I rooted my phone, installed TWPR 2.8 on it. Now i want to go back to stock to take OTA but can't seem to find any stock recovery for my firmware. Thus, i can't even boot into recovery mode. Please help
I don't know if this work but I should try to flash the 1.32 recovery. To get back to stock (S-ON) you need to be as stock as possible (unroot, etc.) then relock the bootloader and flash a RUU. Hope I helped
