A3 2016 after downgrade to marshmallow requires pasword - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Hello
I have tried to downgrade my a3 2016 from Nougat to marshmallow, unfortunatelly after downgrade device requires password to run.
I have tried to use PIN for SIM card or PIN for device protection.
I also found that default_password could be the solution, but it is not.
Anyone has idea how to pass through this password or maybe make downgrade anothe way ?
Regards

I'm not judging but it smells like your device comes from the theft.

Not work
F device Fd owerrite not vork two sim not work two imei
Same thing happened to me a few days ago. To solve the problem I flashed stock firmware, applied root using ODIN, and patch IMEI and certificates using Z3X Box. According to the guy who helped me with the Z3X, there's no way you can make the phone work again without patching IMEI and cert. When fixed, you won't be able to update nor factory reset the phone. If you do so, you'll have the same problem again. It's a matter of KNOX security on the S7 Edge.

Hi Zeth...!
Can you explain why this happens and how to do the job in Z3X ?
I think I need at least version 24.8 (suppport for S7)... can you point where I can get it with no-card loader ? (I was unable to get it).
Thanks...!
Javier.
Well, as far as I know this issue happens because of the new security features on the phone. It has to do with the certificate written on the phone. Once you change it, it triggers an "alert" that is impossible to turn off, unless you patch it again. Unfortunately, according to some flashing sites, it can't be done over Nougat, hence your phone will remain on Marshmallow until a new method is found. I didn't do the flashing with Z3X. I payed a guy to make the process. I've been looking for a card-less Z3X but I only found an older version which doesn't support S7.

Unfortunately there is no solution to this issue yet but if you stay on 6.0.1 you can just use a cert patch and it works 100%, for android 7.0 we must just wait for an update from z3x

Moto Z Force FRP Problem

Hello
I in huge need for you help guys. I bought Moto Z Force 1650-02. After I got I just checked for new Android as always and updated it to 7.1.1 version with 1 september security patch. After that I just facory reset as always. After that my phone want to log on for Google account which was last used in this phone. Seller dont want to tell me what should I type there and he doesnt know about something like FRP either.
So I tried every possible way to bypass FRP and everything Ive done is that I dont have Wi-Fi now and no signal for SimCard. I cant just give phone for warranty because this is Verizon exclusive and im from Poland. For know its just 400 euro wasted.
Pls Help me what can I do with this FRP thing?
Ok I bypassed FRP by myself and everyting is ok except Wi-Fi. It just cant turn on. Any ideas?

You can find step by step instructions on bypassing FRP here: http://4pda.ru/forum/index.php?showtopic=755326&st=700#entry63511470
Just use google translate if you don't understand Russian. Hope link to the needed files there is still active.

[Q] Problem with making/receiving calls/sms and GPS.

Hello guys,
A while ago I was changing my modem and bootloader to other like I did many times, but this time my USB cable got disconnected. Odin as well as phone said that flashing ended with error, so I tried again with another error and after some trying it flashed. Phoned boot up, but not everything was fine. I noticed that my LTE is broken. Phone couldn't connect to it. So I started to search and find that it may be a Problem with NVM. After some time I managed to get LATE working, but after that I noticed that I can't get lock on GPS and I most of the time can't make neither receive calls. Sms are sometimes received after some time.
Do someone know the possible reason ? I will attach log from trying to get Fix on GPS and making call, as well as a screenshot from GPS toolbox.
BUMP ?
