Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Hmm... This is silly! I could send you my /usr/sbin folder but not sure if it will do much :)

I doubt but I'll package it now.

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Yours may be different than his because of installed packages and what-not..

It's better in this case just to reflash.

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

yeah but worth to give it a try though :) what if it works then it saved him from reflashing. Mine hardly got anything installed lol

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Here you my sbin folder.
Put it into /usr/

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Thanks Maxximuscool for bringing this to our attention. Downloaded the unzipped fmtxd file straight to my N900 from Jacekowski's website then renamed the old file and copied and pasted the updated one into the relevant directory using the excellent new FileBox file manager with root access from CepiPerez. No need to mess around with downloading to a PC, unzipping and transferring that way.

No stations transmitting around here anywhere near 87.5Mhz, so no more fiddling about changing frequencies every few miles on longer trips. Looks like I can finally put that ancient 3.5mm to cassette adaptor to rest in my other car now too, so less wires dangling around on the dashboard.

You've made me very happy indeed with this mod!

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

It looks like working OK, showing up 76.0 and starts correctly. But It doesn't stop transmitting? :) It shows the "Unable to use.." error message when I try to deactive it. But It deactivates if I do it with FMTX Widget. Weird. Do you have an idea why?

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Exact same thing happens to me. "Unable to use..." only pops up when disabling FM Transmitter through the menu.

Using the widget to disable the FM Transmitter shows no error though.

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

What can i use to edit this file?

I've tried a text/html editor and a hex editor, neither work.

I want to change it to 108.0 max freq.

My radio goes to 108.0 max, with nothing on 108.0, but using 107.9 i can hear a faint signal of some radio station (before i turn on my FMTX).

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Same here, freq below 87.5MHz unable to switch off transmitter. But if you change freq. anything above 87.5Mhz, everything is working fine.
In my region, there is nothing below 87.5 MHz, Tuners here can't lower than 87.5Mhz. Isit possible to edit the FMTXD file, so that the lowest freq. is 87.5 Mhz???

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Just checked this.

Same happening to me.

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Is anybody working on fixing this ?

Or even just changing the minimum frequency to 87.5 ?

(or my suggestion of raising the maximum from 107.9 to 108.0 ?)

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

The hardware is limited to 108.0 but we can only use up to 107.9 when hacking the Hex value.

It is uncleared on how to achieve 108.0 on the dot. Because if you can set to 108.X then you can set up to 108.9. Which is not logically understandable by the chip.

Minimum frequency is 76.0, you can use anything above 76.0Mhz as your minimum. For example I'm using 87.5Mhz as my everyday usage. This hack is has mixed result. I personally just tried reset my device to default setting and my FM Transmitter complaning again. I'm working on a solution to make it more reliable

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Lol! I've stuffed up! I accidentally deleted my /usr/bin folder instead of /usr/sbin folder. Now reflashing my N900, dued to cannot start up after reboot. lol.

I'm going to test this out once more. Last time I manage to get my FMTXD to work with all frequencies. But just now I only got it to work at 87.5Minimum.

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

I can't achieve the same result I did before I reset my device.. But I found a simple working around method to get to as low as 76.0Mhz.

Simply switch the FM transmitter to 76.0Mhz from the start and then if you want to disable the FM transmitter then change the frequency to 87.5-> 109.9Mhz then disable FM transmitter.

If you want to go back to 78Mhz then just do it and if you want to disable it, simply switch the frequency to 87.5+ again then it will allowing you to disable the FM transmitter.

I'll keep trying to find a perminant way to solve this. It may be restricted to the firmware I'm using.

76.0Mhz -> To turn off, switch to any frequency higher than 87.5mhz

To enable anything below 87.5Mhz simply enable it from the start.

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Good News guy, I finally hacked my FM transmitter to work with all frequencies even below 87.5Mhz is able to switch able freely. There is only one variable that needed to be changed inside the system configuration.

Now the FM transmitter can be disable or enable, change down and change up freely without having to see "Unable to use FM transmitter" message when you changing from 87.5Mhz to below 87.4Mhz.

Solution hacked is very simple. :D
How did I not think of that, took me all night tried to reduce the minimum frequency to hack the system file. But no luck. I had to read through the Developer documentation of the hardware and software to find out how the damn thing works.

Now That I found the way to do it, I'm going to share with you all. ENJOY THE FREEDOM!

Here is the file, simply follow the folder structure and replace the file inside the zip file with the system file. Then you're all set.

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Nokia official Headset.

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

For some reason, even as root, I can't delete this file.

I used rm -f

Did you have this problem?

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

You can't delete it, you can do so by go to the directory through WinSCP and replace it with the one I upload.

Then it will work :)

Otherwise just Edit the file and change the region to 4.

I want to make it easier for people to do so I upload the file instead. But if you are confident with manually editing the file then you can :)
Make sure your FM-Transmitter is off and there process is not running.

Do it by Commandline.
From Xterminal:

root
killall fmtxd
killall fmtxd "just to double check"
cd /sys/class/i2c-adapter/i2c-2/2-0063

if you have leaf pad then do this:

leafpad region

replace the number in the file from 2 to 4.

Save and exit.

Enjoy!

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

I'll try to edit.

I tried to transfer it with an over write and access was denied. So I tried to delete and access denied. I'll just edit it then with vi.

That worked!

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Good for you for staying with this thread.

Yup, them dang documentation files come in handy don't they? :)

I don't go below the standard frequencies because of the limitations of my home FM receivers. I have a large piece of art hanging on a central wall of my house. Behind it I built a simple 2 wire dipole antenna that all three of my household receivers share.

With the N900 rockin' at 120 the upstairs, downstairs, and patio stereo's can pick up the N900's signal no matter where I'm at in the house. However, I usually leave it plugged into the charger downstairs right next to the antenna.

I now have a use for my N800 (upstairs) and N810 (patio) as N900 clients. :)

Did I say "What a life"?

Oh, I almost forgot: :p

If I understand you correctly, there should be no need for FM Faker unless you are using a firmware that doesn't support FMTX. Is this correct?

Re: Modified (UNLOCKED) FM-Transmitter frequency 76.0Mhz->107.9Mhz
 

Correct but at the same time it also incorrect :D

You don't need FMTX Faker to make it work. But you will need it to make it work from 0,1,2,3,4,5,6,7,8,9 tuning frequencies.

Without FMTX Faker you'll only have 1,3,5,7,9 as the tuner frequencies. So if you don't want to do the 88.0Mhz, 88.2, 88.4, 88.6, 88.8 then you shouldn't need it.

The FMTX Faker is here to help unlocking the missing tuning frequencies :)

I had to sacrificed my already working Unlocked FMTX just for the research in hacking this damn thing, also have to reflashed my device as well. I spent countless hours testing this to make sure things work nicely for the community to use :)

Now I can reassured that this hacked is 100% effective.

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

arghhh...*banging head*


i flashed my device, did all the same things and i still cannot use this.


it worked before the flash, but this time i am stuck on 88.6 freq....and no matter what i do, it will always give me a cannot use error.

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

Lol don't worry, don't panic.
Things will be just fine.

1. Uninstalled everything related to FMTX
2. if you get the "Unable to use fm transmitter"

Xterminal: root

killall fmtxd
killall fmtxd

Now you should be able to disable the FM Transmitter.
Disable it and then enable it at 76.0

Go to Xterminal:
killall fmtxd

Go to App manager -> FMTX FAker

Xterminal: reboot

Enable FM Transmitter at 87.5, then change it to 88.5 -> 107.9Mhz
This just to make sure you can go UP! now change back from 107.9Mhz ->all the way down to 87.5Mhz
If you change change it to 87.5 then you're doing fine.

Now change from 87.5 to 87.4Mhz, you'll get the error "unable to use FM Transmitter", Change it back to 87.6 and if you can then this meant you are ready for the next step Limitation removal.

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

LIMITATION REMOVAL:
Disable your FM transmitter and then in Xterminal as root:

Install Leafpad "I would prefer leafpad over vi because of the ease of use"

Xterminal:
root
cd /sys/class/i2c-adapter/i2c-2/2-0063
leafpad region


------------------This is what it should look like in the "region" file.
2



------------------Change it to
4



-------------------Save
Xterminal:
reboot

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

worked like a charm. totally free now, thank you!

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

the only thing i have installed is:

fmtx-faker
simple-fmtx-widget

last time i installed, before the reflash, i had 1,2,3,4,5,6,... now, i only have the 1,3,5,7,9, and it is locked to 88.6.


i have removed all fmtx stuff and reinstalled from the begining 3 times now...same result. i just did what the guy above said about changing the 2 to a 4. just finished rebooting.


errr..."not able to us......."

:/

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

you may've downloaded the wrong fmtxd. try using one from a dif post. wish i could upload mine, but can't exactly atm.

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

I'm thinking of wrapping it up as a package.deb, first I have to learn how to do that. Once I've done that I'll announce it :)

This will help solve people's problem.

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

I got that at the start too. But This is how I fixed it.

Uninstall FMTX-Faker
Uninstall FM Widget

reboot

Download the FMTXD from my first post and delete the old on in the /usr/sbin/

Paste the fmtxd in there now, reboot

Now when you click on it, you'll get "Unable to use fm transmitter"

Xterminal:
root
chmod +x /usr/sbin/fmtxd
reboot

Enable FM-Transmitter
Xterminal:
root
killall fmtxd
fmtxd -d

killall ftmxd

install FMTX Faker

Xterminal:
fmtxd -d
reboot

Once you're restarted you'll see 0....9

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

worked!

great.


should i be able to reinstall the widget or the rds notifier? or will those create an issue?

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

Is the region firmware dependent because i changed the region from 2 to 4 but still i get the unable to use FM when i try disabling the transmitter at a lower frequency. The firmware i use is UK region.

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

You have to follow the step carefully. Region isn't the problem. Region 2 will only have 87500Hz frequency as minimum. But region 4 will enable the use of all available frequencies.

I'm using global firmware but it shouldn't be the problem.

@ceroberts
yes once it worked then installing anything you like :)
Freedom that is.

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

Thanks to MAXXIMUSCOOL it works!

region changed from 2 to 4 thru leafpad and xterm.
works verywell.

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

if you changed the region before the steps described in #151 you might need to do it again afterwards

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

I changed it from 2 to 4, but after reboot it goes back to 2. I reopen region before reboot to make sure I really changed the number.

Any ideas?

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

Mine changes to 2 as well on reboot

does it "need" to be 4?

If so, looks like a fcrontab job is in order.

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

crap, indeed it gets reset :(

Re: Unlocked FM-Transmitter frequency 76.0Mhz->107.9Mhz (Limitation Fixed)
 

i tried making it read only but that didn't help, but somehow it now works even with region 2 (can't turn off while the frequency is out of the standard range though)
