[Q] Flashing Stock Rom

Hello everyone I just bought an HTC One (Great device by the way) it's not available in my country so i had to buy it from france it's the 801n model and it was locked to Orange France carrier but i unlocked it to be used on any other carrier BUT i still have some built-in system apps from Orange that are really useless and I didn't receive the latest android 4.3 update so i Was wondering if there's a way to flash a "STOCK" firmware on my M7
thank u (i'm new to HTC stuff)
Here you can found the stock rom.
However, i advice you to put the phone in s-off if your hboot is 1.44 or wait the tool for the 1.54

Is your phone stock or do you have a custom ROM?
If custom ROM, you will need to have a stock ROM and stock recovery to successfully execute an OTA.
Are you S-OFF, if not you can not flash the OTA files.

[Q]upgrading firmware htc 1 m7

im using htc one m7 802d indian model..(dual sim cdwg i guess)
my software number is 6.15.720.4 android 4.4.3
I rooted my mobile a few days back and installed twrp. I received ota update for version 7.15.720.x after a week.
I tried installing viper custom rom and (installation failed) its representative told me to first upgrade my version to latest and try installing later. For that purpose i need to get a stock recovery of my present version which i could'nt find. and moreover i found a nandroid backup for 4.1.2 version. What should I do and how to upgrade . Please suggest and help me. I'm stuck with this version.
