Help - HTC One in boot loop

[SJGoel]

Hello.

I was in the process of upgrading my HTC One from 4.2 and successfully unlocked the bootloader. But thereafter my phone just constantly reboots. It shows the HTC splash screen for about 10 seconds and the reboots again.

I am able to go into the fastboot screen (see screen shot). But when I select Recovery, the phone gors to the next screen - displays "Entering Recovery" - and nothing else happens thereafter.

Can anyone please help? Have looked at other such questions and tried but nothing has helped.

NB: I have an Asian HTC One, using it in Singapore.
Thanks

You probably want to find the RUU for your device which will allow you to flash it back to 4.2 and in working order. Obviously something went wrong in the process if your stuck in a bootloop and can't enter recovery.

Dear Paul627g,

Since the device is a dual SIM 802d, I need some help in finding the appropriate RUU.

Thanks

have you tried a factory reset?
