So no fw problems? Can you give me why you say hw problems in order that I can confront with your ideas, study them and give good reasons to my superiors to change board? I think i am the deal with you, it is impossible for nothing to work, i just want to see if there is an objective way to prove that there are hardware problems so i can justify it to my superior. Sorry to bother, really.

Does your superisor have any idea?
Provided that supervisor should have enough knowledge to judge

One of them says not hw problem because it’s impossible that don’t work both SPI and UIM. I don’t know what say, I think that module wp7607 has problems… . But my doubt is that the problem could be firmware type ( could I have mistakenly changed something of the initial firmware of the wp module?) or simply hw type. I tried to lounch .exe on windows (in one test release 16 and in the other one test release 13.1) but nothing change. The other biggest problem is that I can’t find other ways to restore firmware on the module because sierra wireless website is off since march 23 😥

Maybe the metal case of module is not contacting well, you can use your finger to push the metal case during testing

The metal case was not-well connected. Now works both SPI (CAN) and the UIM for the SIM. Thank you very much for all your support.
