RUU stands for ROM Update Utility. RUU files are exe files which are used to flash firmware to HTC phones. Not just any RUU will work on a HTC phone. This guide will explain what to consider in order to select the right RUU for a HTC Android phone .

How to know / find the right RUU file for a HTC phone

Setup ADB and Fastboot on the PC
Install HTC drivers on the PC
Boot the phone into Hboot
Select fastboot in Hboot (Fastboot USB should be red in color)
Launch ADB then run this command (type the command and press Enter)

Code:
fastboot devices
Now, run this command

Code:
fastboot getvar all
Some information from the output above are what you will be using, they include:
Product: The RUU you pick should be for your phone model. The phone model in the above example is M7_ul
S-On or S-off: "S" here stands for Security. Its the state of the NAND portion of the phone. S-on means it is locked and can't be written to. S-Off means it is unlocked and can be written to. The S state of the phone is displayed in Hboot.
Bootloader: You will see the Bootloader state in Hboot as Locked or Unlocked. A locked bootloader allows only digitally signed images to be flashed while an unlocked bootloader lifts this restriction. The Bootloader should be locked when flashing an RUU. In S-Off state, this requirement can be ignored
Version-main: The RUU should be of the same version or higher. The Software version in the above example is 6.09.401.5. Here's one very important piece of information.The format of the version-main is often *.**.Provider Location.* . In the above example (based on a version-main of 6.09.401.5), the Provider Location would be 401. Some Provider Locations are:

x.xx.61.x - Orange UK (United Kingdom)
x.xx.69.x - Orange PL (Poland)
x.xx.73.x - Orange FR (France)
x.xx.75.x - Orange ES (Spain)
x.xx.110.x - T-Mobile UK (United Kingdom)
x.xx.111.x - T-Mobile DE (Germany)
x.xx.113.x - T-Mobile CZ (Czech Republic)
x.xx.161.x - Vodafone UK (United Kingdom)
x.xx.163.x - Vodafone FR (France)
x.xx.165.x - Vodafone IT (Italy)
x.xx.168.x - Vodafone GR (Greece)
x.xx.206.x - O2 UK (United Kingdom)
x.xx.401.x - World Wide English (Europe Unbranded)
x.xx.415.x - Arabic (UAE/Middle East)
x.xx.468.x - Turkey
x.xx.497.x - Morocco
x.xx.498.x - WWE Brightpoint US (United States)
x.xx.531.x - T-Mobile US (United Kingdom)
x.xx.666.x - Bell Canada
x.xx.707.x - Asia WWE (World Wide English)
x.xx.709.x - Asia TW (Taiwan)
x.xx.720.x - Asia India
x.xx.771.x - Hutchison 3G UK (United Kingdom)
x.xx.841.x - Telsra WWE (World Wide English)
x.xx.862.x - Voda-Hutch AU (Australia)
x.xx.901.x - TIM IT (Italy)
x.xx.911.x - SK Telecom (South Korea)
x.xx.1400.x - HTC China
x.xx.1403.x - HTC China CMCC (China Mobile Communications Corporation)

In S-Off state, this requirement can be ignored
CID: This is the Carrier ID. The RUU should be for the phone's carrier. In the example above, cidnum is HTC__J15. You should then run a Google search to find out which carrier uses this CID. Note that the CID won't matter if the phone is S-Off and SuperCID. SuperCID is a cidnum of 11111111. This CID is Universal / Global because it is not locked to a specifc carrier and compatible with all. The downside with SuperCID is that it doesn't receive Carrier specific OTA updates.
Some CIDs and their corresponding carriers include:

How to select a matching RUU from a list

Recall that in S-Off (and SuperCID) state, the above requirements (except phone model) can be overlooked; any RUU for your phone model can be flashed. However, in S-On state, you need to adhere to the above requirements. I'll be searching with S-On in mind.
Visit http://androidruu.com to download the RUU for your phone model.
The screenshot below shows a list of candidates for an RUU using the above phone model (m7_ul) as an example.
Your first filter should be the Location Provider which you obtained from version-main in 5 above. In this case, I'll search the page for 401. All RUUs (not OTAs) with 401 ; which is World Wide English (Europe Unbranded) would qualify. From this smaller list, you keep narrowing down if the RUU name carries any other of the above requirements.

I have found the correct files but no matter what i am trying to flash, it says that remote access is not allowed.

I am getting this error, whenever i am trying to flash recovery or RUU

Means the RUU is not signed or not a perfect match

thanks alot. i have a question though,
will the carrier matter if all these parameters seem positive.
for example, i'm using an HTC M7_WLS model with the carrier being ATT. But all i can find is Sprint carriers.

my devices is also Super CID and is S-off.
any help would be highly appreciated.

HTC M7_WLS is sprint variant and should be flashed using sprint firmware. if you're able to use ATT then it must either be that the phone didn't come with any sim network restriction or it may have been unlocked either by yourself or someone else
