- EH 237 NAM programming codes:
-
- FCN 923885 (or M 923885)
- " 924885 "
- " 904885 "
- " 904005 "
- " 904035 "
- " 904085 "
-
- we can see the ESN and modify the parameters for the NAM.
-
- IMPORTANT! With FCN 904030 we can transfer data,(??) THREE o FOUR times
- ONLY. This means you can't clone the phone forever! There may be
- another code offering unlimited ESN transfers, or some test-mode option to
- reset the counter. Experiment, and let me know if you find anything. --Dr.

- FCN 900000 asks for 5 Pin codes -- ??

- EH237 ESN programming:
-
- Either build an ESN Transfer Cable for the Ericsson EH237 and EH238, or
- program it directly from your computer with the Ericsson Software.
- Documentation below.

- At last the Ericsson software is in wide distribution! Thanks to Phoenix of
- CCC for cracking this one. It's been around for a good while now but hadn't
- been released to the various p/h bbs's until more recently. Unfortunately,
- CCC neglected to include any wiring diagrams for the thing so here they are
- for you all to peruse along with a few pointers for running the thing.

-
- ::: Loading :::
-
- I am not quite sure why but this software refuses to load if there are any
- memory managers loaded. In other words, most of you will need to boot off
- a clean floppy rather than your hard drive. To make such a 'bootdisk' use
-
- FORMAT A: /S
-
- from the DOS prompt which will format the disk in your floppy drive and make
- it bootable. I don't know why this is the case since the Cheese Factory have
- never released software with such problems before.
-
- ::: The Cable :::
-
- Much the same as for the Sony CM-H333, the software is self-explanatory, the
- only thing you need to know is how to make the cable.

- Where 21, 11 and 8 represent the numbers of the D-plug pins you must connect
- to. (ie the leftmost pin of the phone must be connected to pin 21 on the
- male 25-way D-plug which connects to the printer port of your PC).

-
- I have _never_ actually made either of these cables, nor rechipped a phone
- with it. Nevertheless, I am told that the way to make the cables is to buy
- a plug-in saver charger (eliminator that goes up the bottom socket) and
- modify that to make your cable from it.
-
- You _must_ buy one with a plug that has adjustable pins. Don't go out and
- buy one with pins fixed in certain positions since you need to slide them
- along into the positions shown above. Some may be fixed into the plastic
- (such as the "Mainline" ones) - Avoid these. If you're lucky the cable to
- the cigarette lighter will contain 3 wires. That way you can just cut off
- the lighter plug and solder the 3 wires onto your D-plug. Otherwise you'll
- need to take your own 3-wire cable from the plug to the D-plug which doesn't
- look quite as 'neat'.
-
- You may have heard a rumour about the Ericsson shutting down after too many
- ESN changes. I'm afraid I'm not in a position to say either way since I have
- never owned one. What I _can_ tell you is that I have a friend who has
- rechipped his at least 30 times with no problems, but I have heard that the
- maximum number is around 40. I'd love to hear from anyone who knows the real
- answer. It may be worth your while not using one of these phones for boning
- a hell of a lot of ESNs on just in case. It's a nice phone to pick up second
- hand and use for yourself...
-
