[Solved] Reverting Galaxy J7 2016 (J710FN) from Android 7.0 to Stable Android 6.0.1: User Experience

How can you roll back / reboot Android 6.0.1 that was perfect for my needs completely. 7 is terrible
If someone wants to know why I want to switch back to version 6.0.1 read my statement below.


Hello. Yesterday, an update of my Galaxy J7 2016 (J710FN) to Android 7 popped out. Earlier my phone hung several times for a year. And I didn't have any problems with it. At the moment, i.e. after yesterday's update, the phone has become inoperable. It freezes, it doesn't run smoothly, Wifi has moments when it doesn't work. Packet internet is extremely slow. I am not getting application notifications. The upper beam has become completely useless due to its hopeless appearance. The clock on the lock screen looks like **** I was only able to set the screen brightness adjustment bar to be on top, unfortunately, to press the "outside" button which is useful and intuitively placed in the previous version, unfortunately, but you already have to bother with entering the settings ... And what's funniest yesterday I lay down sleep and connected the phone to the original charger / cable and overnight it is about 6 hours charged a few percent ... which can even be seen in the screenshot

You need to download the odin and soft program to your phone, for example from https://www.sammobile.com/firmwares/
and follow the instructions of the software - uploading the software. The data you have on your phone will be deleted.

In truth, it won't change anything about the aesthetics of the new system, but you can try to hard reset the phone and maybe then the performance problems will solve.

Do a hard phone reset (factory reset) and it should work fine if it doesn't help the phone for service if it has a warranty. Undercutting android 7 to 6 may damage your phone.

So if I would like to upload 6 now, the system may not stand up anymore? And then when I give back the guarantees they won't recognize me?

This can happen, the last system that could be underestimated without consequences was 5.

I advise you not to use the warranty. If you apply the flag, the guarantee may be rejected.

so the flag is some kind of tag saying it was something tinkered with?
but if he didn't want to get up after this test, it would be good to upload the rain once again?

but how would you after this trial

After attempting to understate it, the modem may be damaged and then even uploading 7 will not help because the phone will be out of range.

I haven't been here a long time. After several attempts to upload a new software. I managed to upload soft, probably from the French distribution with that name
J710FXXU3AQF8_J710FXEF3AQF1_J710FXXU3AQF4_HOME.tar.md5
using ODIN 3.0.4 (other versions could not cope because it bugs)
The system has 99% returned to its previous state. The only difference I noticed is the inscription 4G instead of LTE above the range indicator.

KNOX 0/0, i.e. the flag has not been stamped
