My phone is S-ON and is not rooted.
I had installed HTC Marvel_S EU 2.13.401.2 with gold card. It was working very well.
I tried to update HTC Marvel_S EU to 2.13.401.3 with my gold card.
After installation of update phone tried to restart itself but the screen is flashing with back light and phone does not work.
Volume + Power do not work.
Removing and reinserting battery do not work.
What should I do?
Unfortunately once the device has updated to the most recent software it cannot be reverted to the previous update allowing the device to be unlocked. I can escalate this issue as a feature request to see if a further Hboot update can be released in the future for users who may have missed the opportunity to unlock their devices.
I hope that this information meets with your requirements. Should you have any further questions please do not hesitate to contact me again.
You will not be able to unlock the bootloader until HTCDev updates its RUU.
I am sure that my phone is S-OFF. It was blocked on O2 United Kingdoon. Now I use Orange in Romania..
