JP1 Remotes

I think I'll declare this hopeless and discard the remote.
I tried downloading the remote, then installing the extender, and then holding setup to deactivate the extender. No luck. the CBL button blinks twice then after a few seconds it blinks twice again. Then pressing TV, the CBL button blinks twice and then TV blinks once.
Tried clearing with 980 and 981 then uploading an rmir file from a brand new remote. Then pressing TV causes CBL to blink twice. After that, no blinking from any of the device buttons or any other button.

If anyone would care to look at the files, I've uploaded the rmir file from the dead remote without extender at this link:
without extender

And the rmir file from the dead remote with the extender installed is at this link:
with extender

If THIS clean file doesn't work, PM me and we'll try plan B.

I may be confused here, but if dannyo's remote still has an active extender in it, I think that the file to upload must have at least a signature of 3A793A79 rather than 31793179. But both of dannyo's files and mdavej's file have a signature of 31793179 on the Raw Data tab.

So I would think (but am not sure) that the clean file to upload should be generated by using IR.exe, File\New, and selecting the extender RDF. I don't know how to get RMIR to make a clean extended upload.

Just to clarify, my clean file was downloaded from an RCA out of the box, not made from "File-New", so it is the base config the readme recommends. I couldn't tell if the extender was ever actually loaded or not. Something to try would be similar to what eferz said, but start with my file, then merge with ext-install, upload and activate. Then try to deactivate and 981 reset. Failing that, my plan B is to reflash the entire ROM which I've had to do myself on a couple of occasions.

The scrambled extender RMIR file was also scrambled for me. Couldn't read a thing.

eferz,
The fact that the readback signature is 3179 doesn't tell us anything about whether an extender was loaded. It just tell us that subsequent to an extender being loaded, something else was uploaded to the E2 area, and of course we know that has happened.

Anyway, I believe that an extender was loaded because if one isn't loaded. and an E2 image from another RCRP05B is uploaded, the remote will work. dannyo tried that.

Regarding the quote in red about File\New, The RDF file included in V1.32 does correctly setup the E2 area using File\New, at least for an unextended remote. I went to some effort to make that work. Of course, if one has a the subject remote, it's fine to start with a download.

I think mdavej's plan of action is a good one.

mdavej,
I opened RMIR 2.02 beta.
Opened your clean ir file (without [general] and [settings] stuff.
Installed the extender with file/Install Extender... (raw data changes greatly)
Then uploaded (green lites blinking on usb connector)
unplugged remote.
Pressed TV then OK to activate.
CBL blinked twice then TV Blinked when TV was tapped.
CBL blinked twice when OK was tapped.
Then I tried to deactivate with a long press of the setup button.
TV blinks twice immediately then blinks twice again after a couple seconds.
Then tried a 981 reset by holding setup.
TV blinks twice immediately then blinks twice again after a couple seconds.
I tapped the 9, 8, and 1 buttons.
Each number pressed causes the TV to blink twice and then CBL blinks once.

I would expect two blinks after the 981
Now the TV blinks twice when tapped.
TV blinks twice and then CBL blinks once when CBL is tapped.
CBL blinks twice then TV blinks once when TV is pressed etc.......
If I tap a device button a second time, it blinks twice.
I'm thinking the remote is still scrambled??

I'm somewhat confused by the use of the term "executor". Perhaps you mean "extender". Anyway, I don't know if the File\New will work with an extender. Probably. Very Happy

Regarding the signature, it resides in flash memory and you can change it by entering a new value of the Raw Data tab. For example, using a non-extended RCRP05B, I changed the sig to 3579 from 3179. That uploaded fine to the remote, and downloaded too, although RMIR complained that it had no RDF file to match 3579. It is still possible to change the sig back or to do a 981 reset, in which case the remote will set it back to 3179.

So even though dannyo may have installed an extender, depending on when he saved his download from the extended remote, it may have the wrong signature.

The name E2 memory is a leftover name from when remotes used EEPROM for memory. Most remotes now have around 64Kbytes of flash memory, and most of it is taken up with UEI firmware, which we can 't access with RMIR or IR. However, some of the flash memory is intended to be modified with upgrades, keymoves, macros, and learned signals. We call that the E2 area, and RMIR overwrites all of it each time it uploads an image to the remote.

The E2 area is the part of memory (the only part of memory) that RMIR or IR reads from and writes to. When you download from a remote, the entire contents of E2 is read and displayed in the Raw Data tab. And when RMIR uploads to a remote everything that was displayed on the Raw Data tab is written to the remote.
