I cannot find a sim in my dm520hd (genuine).

Hi.. I have opened up my DM520HD and cannot find a sim card or sim card holder anywhere.

I have spent hours going through the forum looking for photos or videos but to no avail.

Could someone please confirm that my genuine DM520HD has a chip in it and if so where is it?

My board is marked as DM520S_V04

ta..

You should have something like this, below (from DM800HDseV2 but pretty same), this for the ORIGINAL DM520HD.



And a photo of an original with Original Sim, then they put chips,



Motherboard V03,

Thanks for the quick reply.
My board is v_04 and has not got the socket.
I know that you can source the socket but i know that i have not got the skills to attach it.

Picture of the board is attached.

Card,

Admin

Sorry, i do not understand.
If it is possible to put the sim onto a v4 board could someone who has done it please explain what parts need to be put on and which part(s) if any should be removed.

Yes, you can change your box into a Japhar Sim box,

You need to remove carefully the "chip" that you can see on the photo (unsoldering it), and then solder the sim support. Then you can insert the Japhar Sim in the DM520HD box.

Chip to be removed :



Solder the Sim Support/socket, you find here,

And then the sim can be installed, that you can find here,

Hope this helps and to be enough clear,

Thanx for the detailed info.
I have just ordered both items.

Sorry to be dragging this post on...
I am about to take the dm520hd in to have the soldering done for the holder to house the Japhar sim.
Following the instructions, I was trying to load a Japhar image which was
openpli-enigma2-7star-dm520_Japhar.rootfs.tar.cz being OpenPLI 7*.
It failed with 'Boot image is too big'.
Should I have the sim holder done then try again with the sim installed or find a smaller Japhar image (if there is one)?
Please advise

It is good, don't worry of these errors.

Just reboot the box and it will work.

But please before removing the chip please contact Toysoft, as he would like you to run a script in the box first, and then after do the upgrade to the Japhar sim from the chip.

I did reboot the box and it went through the startup ok (screen, internet etc..) BUT it could not see the tuner... So I restored my previous image (OpenATV 6.2) which restored and worked fine.
I will PM Troysoft)

The Tuner will work only if the driver is the correct one with the correct sim for it.

Admin

I connect to this thread, to tell you that if you need to replace the chip with sim japhar, I can do the job.
