answer 1: who is stopping you from turning it on and make a try???
answer 2: presumably yes, via Odin, using the relatively easy keys sequence (step a going to download, step b confirming by vol up).
Well my friend,
sorry for the late response.. didnt expect anyone to post here
i may not be a very experienced user but i have some knowledge and tried accessing it with adb and samsung sidesync but didnt work.
display shows nothing just the sound and vibration if i press back and menu.
back to my kernel question - can i flash a kernel and turn on usb debugging with a zip ? or with the kernel like maybe there is a kernel which turns usb debug on by default
edit: a custom kernel is flashable with odin ?
thanks for your answer

you want to go back to nougat from oreo , am i right ? Then try this video, if it doesnt help please reply to me and i am gonna find a solution to you ASAP
1) https://www.youtube.com/watch?v=qqpucWXyfqY
hi. thx, but i did this right (like in the video) many times, and it worked perfectly. now is not working cuz the bootloader was updated, and it won't let me downgrade the firmware anymore. i am still trying to find a way but i don't know if is possible.
i am searching a way to downgrade bootloader and then downgrade the firmware, but i dunno if is possible to downgrade bootloader once it was updated.
i am looking for the same solution. i managed to downgrade to Nougat but cant install custom rom
Can someone help me? I have G950FD which Firmware should I flash for my phone? I am using this model in the US
So no solution to downgrade bootloader version?

I have searched the whole web. but, I haven't find the solution to downgrade the bootloader for Binary 6. Well, my phone's OS is dead after upgrading to pie. So, apparently the only way for me and to others who are facing the similar issue is to wait until someone releases Binary 6 combination firmware for SM-G950FD.
Good news: It's easy to get your phone running if your bootloader is not upgraded to binary 6. Cuz, Binary 5 firmwares and combination files are available out there and they are 100% working unless your MB is dead.
Note: I have flashed following stock firmwares successfully through ODIN [INS-G950FXXU6DSK9-20191231094010 and INS-G950FXXS6DTA1-20200120123810] yet no luck. Can't boot the OS. Tried to root the phone, cant able to flash the custom recovery. Nothing just works.
Someone, please tag me if ever finds U6 combination file. That's the only hope to bring back my phone to life.

India has Xiaomi Store with support, right?
If it re locked the bootloader just bring it there (don't say you unlocked it) and let them do they're job for free since it's in waranty
you should go to the expert who can be fix that., Go to the store.
You can fastboot the stock firmware but i sense you done it already
just a phone no matter how much premium you pay for it. try not to get depressed about it. these phones are usually replaced every few years so it's not a permanent life long partner either. hope you understand what i really mean. please don't be depressed about such things. you can't control each and everything in life. you can only guide but not control n if something doesn't work the way you want there is no need to be depressed about it.
Just go to fastboot mode and unlock your bootloader again. After that fastboot the Indian rom again without "clean and lock" option.

hi guys some help pls :) re install rom?

Hi guys, my nephew has his gave his phone to me, i can have it for my kids.
I tried to put it back to factory setting by recovery mode and it says failed to find misc partition.
my guess is flash it from download mode with odin into a new rom ?
Also what rom should i take because i cant really get it clear what kind of phone it is, from the netherlands.
Yes maybe some dumb questions but better safe than sorry
Thats a Galaxy A5 2016, model number is A510F as shown in your pic.
You should be good by flashing the latest stock ROM through Odin.
thanks, ive did that yes with the stock rom, only prob now is that it has FRP protection on..
