hello to all, I have a serious prodlema with the model asus zc520tl MT6737m processor and 6735 hardware.
The problem for which I strongly ask for help is that after an automatic update, the phone no longer detected the SIMs; I tried to flash several ROMs, both Stok and Custom, but none of those tested solved the problem. I found a ROM Stok that sees me the SIM, but there is no network for any SIM.
I have tried everything, but I can not succeed and my phone can not be used.
I've tried several STOK updates via Recovery and asus ZIP files and it tells me that the phone is a phone ID, although now the build version is MRA58K.WW_Phone-13.1.0.91-20170306.
With this version of Build, the phone does not see the SIM, with the version ID_ZC520TL_13.1.1.70_20170421
the phone sees the SIM, but there is no network.
I pray for help ...

Which of the build firmware is currently on the phone? The one with no network or the one that doesn't detect sim card?

Flash the ID_ZC520TL_13.1.1.70_20170421 rom then check if the phone has valid Baseband & IMEI

Thanks innagee for your interest in my problem.

hello innagee,

I flashed the Stock rom ID Phone 13.1.1.70; 

the phone finds SIMs both, IMEIs are correct (first: 3519290874..8 and second: 3519290874.36)
BASE BAND: MOLY.LR9.W1444.MD.LWTG.MP.V88.P71

The result is that the phone doesn' find any signal....no network......

I strongly ask for help to you and anyone else who can give me some advice, because I read everything and tried everything I could .......

Have you tried switching network mode to 2G and Network Operator to Automatic?

maybe you flashed the wrong firmware ID / build
do you by any chance remember the original ID of your phone before performing the update? 
check the firmware list at https://www.asus.com/us/Phone/ZenFone-3-...Desk_BIOS/

hi X3non, my phone was selling pair promotion with a twin that now has the build NRD90M.WW_Phone-14.10.1807.110-20180705 and it works perfectly.
But when I tried to flash the ROM stock that has the twin, I received the message "invalid scatter file" from SP Flash Tool ...... I do not know the reason ...... Paired phones, different as hardware ? .... I do not know .... but the firmware that works on the twin, I can not flasharlo .... NRD90M.WW_Phone-14.10.1807.110-20180705 .... also because my phone seems to be a MRA58K and not a NRD90M ....... I do not understand any more .....
Thanks for your help.
