No trudno. Ciężko będzie się doczekać normalnie działającej wersji. Spoko byłoby, gdyby oficjalnie LineageOS zajął się J7. Bo widziałem, że można pobrać od nich oficjalne wersje na A5 i A7. A A7 ma mniejsze zainteresowanie niż J7. Niemniej jednak bardzo dziękuję za informację. Pozdrawiam! :)

I hope you didn't unplug your phone from your PC when rebooting. Phone has to be plugged in to enter recovery

I hadn't unplug my phone during the reboot

or you can use usual method:

connect phone to charger/PC and turn off your phone. Hold power + vol up button and counting will begin. When counting ends, hold for 2 sec more and it should boot to recovery.

Yes but it doesn't work I have the error "No command" I tried also power +vol - but it's just the fastboot mode.

When you get to the no command screen you have to press power + volume up. There's a trick to it, I don't get it all the time either.

Dm-verify error…

E:failed to mount /system (invalid argument)

I can see that in recovery I still have the firmware from switzerland G930FXXS2RC3 instead of UK G930FXXU2ERD5.

In download mode I can see Secure download: enabled and FRP lock : ON, I also remember that i didn't toggle the OEM unlock since flashing official firmware you don't need to be OEM unlocked.

Download BTU Oreo stock files.

have the same issue hear odin keeps failing flash and in recovery it states the same as you did you come across a fix ??
[Samsung Galaxy S7 Questions and Answers] Mr.Januzi:
Hello bro.

I did not come around any fix for that, I had to take it to a repair shop and they fixed it for 40 euros.

While searching on internetil I found some guys who said that they could repair it via Teamviewer from their shop but also had to be paid 35 dollars.

After a while, I found a program which is called ; Octopus Box Samsung which seems to repair NVM, write firmware on samsung phones. I haven't tried it but I'm sure it would work if you do a little research on it and watching tutorials on how to use the app.

Best of luck, and let me know if you come to a fix.

Edit: apparently you need this program and a Samsung Micro UART cable with 530k resistor in irder to work.
[Samsung Galaxy S7 Questions and Answers] kmcmahon079@gmail.com:
i see its tricky situation that i have never faced and need to fix my phone.. what is NVM ? i do not have Octopus Box but i do have Z3X box but and uart cables dont see that option at anywhere what is NVM what does it do and can you tell me where u seen this post ?
[Samsung Galaxy S7 Questions and Answers] Mr.Januzi:
NVM is the memory of the phone on which your firmware operates. I never used the octopus box but I read for it on google.and watched som.youtube videos on which they repair NVM through the octopus box. I never heard about z3x box but I assume it does the same function.

[HTC U Ultra Questions & Answers] inFiniTyz_Z:
Hello my friends.

I bought my U Ultra in December 2017.

Now I decided to flash LeeDroid Oreo on my phone.

It works great.

I backed up in TWRP the parititions "System Image" and "System" in case for going back.

Now my question.

Is it possible to go for going to stock when I recover it all?

Can I lock the bootloader after that?

How to use the "System Image" partition? Can I fully flash my phone to stock with it? With Recovery and so on, because there is no RUU available for me?

My System Version was 2.21.401.1 and my region is Europe/Germany.

Regards
[HTC U Ultra Questions & Answers] QDT:
If you have TWRP backup you simply recover the backup, wipe data and you are back to stock-ish. Naturally due to lack of original recovery you won't be able to receive/flash OTA. For HTC you simply do not exist.

Kind of. You can make OEM lock but it won't be the factory lock. It will be relock. And if you have a custom ROM at that point the phone may not let you boot up.
[HTC U Ultra Questions & Answers] inFiniTyz_Z:
In case when I flash the stock recovery too?
[HTC U Ultra Questions & Answers] QDT:
If you restore whole system then you will get the OTAs. (This is how I upgraded to Oreo in the first place).

Problem is with TWRP/custom recovery not being capable of performing the factory update (people are soft-bricking their phones).
