Easter break so time off. Yes you can, but I'm out at meetings today. Suggest you first backup 100% working rom im TWRP.
 
I meant I was on holiday for Easter break we get over here, is all.

To update firmware you have a few choices, in order of risk:

1 - Safest option - Go back completely to stock by flashing a stock recovery, and then accepting OTAs to get up to date.

Download stock 1.54.401.5 recovery here: https://www.androidfilehost.com/?fid=95897840722641412
and fastboot flash as you did with TWRP.

2 - Next safest option - Use a complete RUU zip if there is one available that matches your cid and mid numbers

Download one of the RUU zip files from here: https://www.androidfilehost.com/?w=files&flid=24562
the higher the numbers the more up-to-date, so latest is 4.16.401.10 released as part of HTC Android 5.x update.
Follow this to install:

Alternative, which is using the RUU zip file if none of the above work.

There are full RUU zip files available that should allow you to update your firmware and get you back to stock rom/recovery as well. This is normally a last resort step but if you can't get to the TWRP backup links, it's an option if you don't want to try different ROMs until you find one where everything works.

Note : if you have anything on your phone in internal storage you want to keep (photos etc) copy it all over on to a PC first - this will completely wipe the phone's internal storage.

You need the file listed here, this will also update your firmware to 2.22.401.4 as there aren't any for your older firmware that I could find:

https://www.androidfilehost.com/?fid=95916177934516315

Download it and check the md5 matches exactly.

Rename the file to be 0P6BIMG.zip (first character is a zero, fifth character is a capital letter I) and copy to the root of your sd card - don't put it in a folder.

Reboot to bootloader, then using vol buttons highlight HBOOT in the menu and select using the power button.

The bootloader should then recognise the zip file and work through installing the full stock setup, your phone will probably reboot a few times during the process this is normal.

Once completed, been reading that this might have to be run again to properly install the firmware. So if process asks to reboot once complete do that, then reboot to bootloader and select HBOOT again, and go through the whole install again.

Once complete then delete the 0P6BIMG.zip file off your sd card, otherwise if you go in to HBOOT again it will re-install the whole RUU every time.

Then - Power off. Volume down while powering on.

Above the instructions it should say FASTBOOT highlighted and at the top of the list below, HBOOT highlighted.

Tap power to select HBOOT.

HBOOT screen - choose and select FACTORY RESET.

FASTBOOT screen - REBOOT.

Note : this will also remove TWRP and reinstall the stock recovery. You already know how to fastboot flash TWRP back again.

Good luck.

3 - Riskiest option (not because of the process itself, but what you can do afterwards) - Use Sunshine at a cost of $25 if it works to gain s-off, to completely unshackle your phone and hence be able to install whatever firmware you want (amongst other stuff) - but at the risk of bricking your phone if you don't know/pay close attention to what you are doing.

I'd recommend you take the first option or the second one at a push.
 
Why download the stock again ? I have the stock 401.5 done stock flashing...while using it asks me to update firmware to 401.10 i installed it...it goes to twrp and i dont know what to do next
 
Not the stock recovery, what you have is the stock OS (rom and kernel). The link for option 1 is for the stock recovery image only, you still have TWRP custom recovery installed. You won't get OTA updates without the stock recovery. That's why you get the notification to update, but the update won't install because you have TWRP. Nothing will have installed. You do know what to do next, flash the stock recovery, then reboot and check/install the OTA.
