Change FrSky ISRM Mode (EU/LBT & FCC) via LUA Script
Some customers of new FrSky remote controls have the problem that the internal module can no longer be flashed from EU to FCC and vice versa. This is noticeable because FrSky has sent out wrong ISRM versions to customers. Following complaints from some customers, FrSky has now provided a solution to the problem but wont publish it offically. I think the solution should be public, so I’m releasing it here on my blog.

What do we need
- OpenTX 2.3.0 or higher
- SD-Card
Step 1: install OpenTX
You have to install at least OpenTX 2.3.0 on your remote!
Step 2: check ISRM Mode
Now go to page 7/7 in your „Radio Settings“ and select „Modules RX / Version„. There you will find information about your ISRM module.
Step 3: install LUA Script
Download the LUA script (isrm_mode_1.lua) and copy it to your SD card in the folder „Scripts“ -> „Tools„.
Step 4: run LUA Script
Now go to the folder „Scripts“ -> „Tools“ and execute the LUA script (isrm_mode_1.lua). To do this, select the script and press and hold the joystick until a submenu appears. Now click on „Execute„.
Step 5: change ISRM Mode
You can now switch back and forth with the joystick to change the mode of your ISRM module.
Step 6: Check it!
Now check if the module has accepted the setting! Finished!
By the way: You don’t have to rebind your models!

Works perfectly on X9 Lite but not on X9 Lite S
I have an Taranis X9D+ 2105 with opentx 2.3.39 but on screen 7 there is no info about modules/ rx version

Working like a charm!! thx for sharing neighbour. greetings from NL
Greetings Back! =) #staysafe
I tried with a Taranis Q x7 but it did not work, I get a syntax error.
Is it a different lua file for each transmitter?
It just works on remotes with ISRM Modules! Are you sure you have one?
Hi Phyl! Great help, but how do you found the isrm_mode_1.lua ? where can I found it? Can you send it to me? Thank you!
You can download it here from this page under the section „What do we need“!
Hello, I have made a small adaptation of the lua script to use it with a tool in the Horus 10X Express, if someone is trained to try it, I have only tried it in the Companion simulator, send me an email and I will send it to you.

The modification of the script has been tested by several users and in all cases it has worked correctly.

Hello Phil.
Do you have any solution for horus x10s yet?
Nope, nothing new as i dont habe a Horus here! 😉
Hallo, ich habe das Skript „isr_mode_1.lua“ geändert, um es an Horus X10 anzupassen.
Ich habe es nur im Companion-Simulator ausprobiert und der Präsentations- und Tastaturteil funktioniert einwandfrei, aber das Lesen und Schreiben des LBT-FCC-Modus konnte ich nicht testen.
Wenn Sie es unter Ihrer Verantwortung testen möchten, haben Sie es hier …

Hi, any news on that Horus script, this one is not working.
As i said without a Horus in my hands, i cant programm it! Sorry guys!
Does this work for the X7?
Yes, if you have the ISRM Module!
Herewith confirmed by me, also works on my Taranis X9D SE 2019.I managed to flip it from ISRM 1.1.3 FCC to 1.1.3 EU.
GREAT contribution Phil, thanks !
The error you get on a Horus X10S is: „attempt to call field ‚drawScreenTitle‘ (a nil value)“
Yeah, thats maybe because if the different resolution of the screen. I might try to reprogramm it but i dont habe any remote to test it.
Does not work with ISRM FW 1.1.3 🙁
Ay sorry my mistake 🙂 Using this script I have had set model with R9 external module so ISRM module is off.
In this case and script can’t switch frequency.
Changing to model using ISRM solved issue.
BTW works with XLitePro. Thx for sharing.
??
Is there a script for the Horus?
Not yet, try the X-Lite Script. There might be an issue displaying it but there are just two coammands which get executed, so it might work. I try to get an universal LUA Script for that!
Greetings,
Phil
That is not working, I have tried that
