Galaxy s5 china

[Giordano]

Hello everyone.
I bought this phone because I needed a device to make calls. He worked it and not 2 hours after the network has been blocked.
I do not know how to show the picture because I've never participated in a forum
Using the program MTK Droid Tools I extracted this information:

Hardware: MT6572
Model: GT-i9600
Build number: ALPS.JB3.MP.V1.2
Build UTC dates: 20140504-083004
Android v: 4.2.2
Baseband v: -----
Kernel v: 3.4.5 (linux @ XzServer)
(gcc version 4.6.x-google 20,120,106
(prerelease) (GCC)) # 1 SMP

I do not see any IMEI

There are two (2) months that I try the firmware on the web and believe me, I'll have downloaded at least 10 but I just get error messages when I use SP Flash Tools.
I ask you, if you can, your more than welcome help.
Thanks in advance.

Thanks for the suggestion but my phone is already root.
The IMEI not him since the day I bought it.
However it worked. Then he did not do anything. The signal is blocked by showing
the signal barred (see photo).
After began to crash all app one by one.
My idea was to try to restore the firmware, but from what I understand,
I think of not being able to do this even though I have studied all the ways feasible.
If you are able to help me I'll be happy.
Otherwise I know I have thrown away money ....

The link was for manually setting your IMEI. Try it out and see if that will help solve the network issue.

What errors are you getting when you try to flash?
