How to fix a Galaxy A7 that keeps asking for FRP code after restarting

Samsung devices have anti-theft protection called Factory Reset Protection or FRP to prevent thieves from using the phone. While FRP has become an effective deterrent over the years after its loopholes were patched, it can also be a real headache for legitimate owners from time time. In this post, we include one case of a Galaxy A7 device that keeps asking for FRP credentials when it’s restarted.

Problem: Galaxy A7 keeps asking for FRP code after restarting

Hi there I was wondering if you could help me. I bought a Samsung A7 from a friend and handed it into a repair shop to get the network unlocked. I got the phone back and it worked perfectly. Until the phone died. When the phone died I charged it and the black screen came up saying Samsung A7, but on the top left corner in tiny writing it says it needs the frp code in red. So again I brought it back to the shop, who once again fixed it. 4 or 5 days went by and again it was perfect, until it died and the same thing happened again. I’m a bit confused as when I go through the setting I put in all my own details, register it to my own Google account, but still when it dies it’s requesting an frp code. I’ve tried holding the button off, home and volume key down but it keeps bringing me back to the main black screen with red frp warning up in the left hand side. Can you help please.

Solution: It’s impossible for us to know exactly what is going on since we can’t examine it first hand. But based on the circumstances you mention, there must be a software modification done to the operating system that allows it temporarily become network unlocked. Ideally, network unlock codes should work even if a device is restarted. In your case, the network unlock modification appears to only work in one particular session and once the system reboots, the software reverts back to its defaults.

To get a more accurate explanation why this is so, kindly talk to the technician who modified the software. Their network unlock system is probably designed to work on one active session only. Unlocking a Samsung device varies by phone model and software version so you must get firsthand information from the person who modified the system to prevent the software from resetting to its defaults.

Performing a factory reset for network unlocked phones is not recommended as that can cause the problems you have right now. Ask the person who fixes your Galaxy A7 what to do in order to unlock the phone if ever you’ll do a reset again.

There’s no universal software that can network unlock all Samsung devices. Because carrier firmwares have their unique coding setup, each unlock procedure varies across devices or firmware versions. Third party shops use special hacking tools to modify the software of a device. These tools are not sanctioned by carriers or Samsung so there’s no official support for devices modified by them. A coding issue due to network unlock procedure can vary as well so it’s highly recommended that you work closely with the shop or technician that modified the software of your device.
