Hello friends. He knew; I'll tell you what happens to your celu. In the 1st place, you should say that version of s5 have and, depending on her I say if you made a mistake or not to release him x certificate (release x certificate equals IMEI change.) At the end of the s5, if we had to change IMEI for desbloquearles but no longer. All right; if your tel is a Qualcomm (g900a; g900t; g900f; g900m etc ..) you have is damage on the network, the product of changing IMEI (not always the case) which have disrupted you a file that is only called Qcn in Qualcomm processors, not the Exynos (sm g900h.) this alteration and each time we change or repair networks is common, one must Flashar the respective Qcn. Imagine, I use the word Flashar which means you'll have to take what the technician to realize. It is not no big deal, so do not let yourself killed for a steep price. Greetings from Dom Rep.
