BlackBerry Q10 not reading sim card - sim slot replacement tutorial
 

In this video you will find out how to replace SIM slot on the mainboard in your BLACKBERRY Q10:

I've made quite many such a repairs, in my opinion you should increase temperature to make it more easy, above that good quality video bro!

If you increase temperature you'll cause irreversible damage to the mother board, so I think it is not a good idea.

Can I make it with only hot air gun, is it safe to provide such repair with such an equipment?

please i need the blackberry leap sim ways anybody wit the solution

muhamalak you need professional tools, there is no other way, using hot air you will destroy the mother board!

I have replace the sim slot but now I get no signal network, what can I do?

It is probably due to the mainboard defect, I solve many network problems by replacing IC, here is the exemplary video:

What kind of flux should I use?

I reccomend HF Rework Jelly Flux, very good flux for soldering on mainboard

I need to stick the chip cover to tha mainboard, what adhesive do you reccomend?

I also have trouble with adhesives they are mostly to weak to keep the back cover to the frame. Almost all back covers are coming off, need some solution!

You can sratch the ground portion near the part of the cover you want to hold in place and then apply solder to connect the part to the board for strong support.

I agree. The back cover wont hold if you don't clean the frame properly, use the proper liquid.

I need to do some soldering stuff and need leaping ways, anyone could share the scheme for it, thanks in advance.
