I just unlocked bootloader yesterday, I change from PLK-L01C636B130 to PLK-L01C432B140.
What I do is I flash boot,cust,recovery,system of desired region firmware via fastboot. Then you flash FULL firmware the desired firmware via force update mode (power+volume up+vplume down). After finish, you can enjoy new firmware.
Goodluck !

well i was not aware of that and it seems much easier thanks.. i went through that because force update gave me error when using debranding method of the tool due to flashing wrong recovery img and the right one wasnot working on it just redownloading with no use
My P9 Lite (VNS-L31) has the C900B114 firmware ever since I bought it and I can't get OTA updates. After searching around the forum for similar questions I came to the conclusion that I have to manually flash C432 firmware but I'm not that familiar with the whole process...
Do I have to unlock the phone's bootloader ? (That would also void the warranty, wouldn't it ?)
Or can I install a C432 firmware directly from my SD card with the menu that opens if you dial *#*#2846579#*#* ?
Thanks in advance .

You have to do the entire procedure for debranding your phone.
So: unlock bootloader + twrp + root + flash C432 oeminfo + repair firmware from dload folder with stock firmware C432B130/B160.
Yes, that will void warranty, but if all works smothly (some may works wrong - result bricked device...) you have a C432B130/B160 stock device (bootloader lock, stock recovery, unrouted).

Im with the same issue. What happen with your problem at the end?
I bought BTV-W09C209 version, and bricked it as I tried to install nougat of different firmware versions.
now, I restored it with the version of firmware Full-OTA C100B006. But whenever I try to upgrade to nougat, it shows build number NTV90M test key and instabilty.
I think it's because of original oem info, so it might be a solution to change oem info file..
I know how to do it(I read https://forum.xda-developers.com/showpost.php?p=72148685&postcount=108)
only thing I need is a backup of europe oem info file. where would I get?
Is there anyone to give me some oem file or help..?
Hi there,
The download in firmware finder should ask you if you want to download multiple files hw_eu.zip and update.zip (something like that).
Download both and flash the update.app from both files one after another, this should get you rid of the test-keys.
Regards,
Benjamin
.
Thank you for reply
I already tried installing hw_eu update and it didn't change anything.
Country region still hw/speceas
Hello, I have recently installed Android 8.0 (Unofficial) on my S7 edge as mentioned in this thread by ProtoDeVNan0. And also installed TWRP recovery as explained here to upgrade it. After installation figured that it has some issues with some features.
So now I am trying to downgrade to the latest official firmware.
But every time I download and install the official firmware zip file using TWRP, it says the zip file is corrupt. So I tried downloading from different sources and still it says it is corrupt in TWRP.
And then I tried using Odin after extracting the Zip file. Using the tar.md5 files inside it. It fails as well.
And also found no way to install the official recovery.
Is there any way I can downgrade from 8.0 to official 7.0? And also I would like to remove TWRP and install official recovery. Basically returning it to its original state.
Searched a lot and found no possible ways to do so.
Please help. Thank you
SOLUTION:
I have found the solution to the issue.
I previously tried using odin to load all the packages in the zip file all together which was the reason i was getting the error.
The solution is to tick and select AP file only in odin and start.
(in case stuck at meta-data unplug)
Then reset odin and re-start the phone into download mode again.
Now tick and select the CSC file (not HOME_CSC), and then start.
After the phone reboots, a factory data reset will occur and phone boots up.
Why are you using TWRP to attempt to install Official samsung firmware?
You do it all through ODIN, it'll put your device back to basically original setup state with stock firmware. Flash with CSC and not home_CSC, I assume you have no data you will need to backup before hand.
More info here:
http://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin
Which Version you use odin? I try your solution but dont work on my g935f?
BL not downgraded!

STILL NOT DOWNGRADED!!
You can apply the solution described above (using ODIN to flash AP, CP and CSC with a previous version of firmware). However, the Boot-loader will remain under the latest version (since January 2018 update).
The problem is drastically worst for those who used to patch certificates before the January 2018. For those users, I will advise to not install the update from January 2018 because, they will not find any tools currently available to patch certificates and get the phone work a new. They can try but it will not be successful and the phone will keep saying "Emergency call only" or "not registered on network".
Anyone having successful experience to inform others please!
Thank you.

Yes it Solved. You Need to have Stock Firmware of March , and extract PIT File, then flash Firmware with PIT File.
In Options tab check "F. Reset Time", "Auto Reboot", "Nand Erase", "Re-Partition" and "Phone Bootloader Update". Rest options must be UNCHECKED!!!
If anyone need Firmware of March for G935F and the PIT , then let me know.

I also experienced the same problem. I just tried installing android 8.0 (from the same link and way as you explained) and it works. but after I tried several times, a lot of bug that makes me uncomfortable.
So I plan to restore it to the official/original firmware version as before. I've tried using odin and also the same as you experienced, always fail when installing BL. And AP, CP, CSC works well.
Then, what should i do?
Can someone please help explain to me more clearly? with more easily understood words. My English is not very good, I still have to use translator for sentences that I do not understand. I would appreciate your help.
Thank you

after trying for many days got this Solution.
The baseband should be same or higher of the firmware to downgrade.
Example: G935FXXU2DRAG Oreo
G935FXXU1DRAG Nougat ( will not happen.)
Both should be same I mean the U2 in the middle.
Or u can downgrade upgrade from U1 oero to U2 Naugat. But not from U2 to U1 Baseband.
Hope it helps.
Just download last nougat release and flash it using latest odin simply guys,
I have tested, no one needs to use pit file or nand erase etc. Use samfirm to download latest firmware for your model. Then use latest odin to flash. Be sure to use normal csc file, NOT the home csc. You don't need pit file when using normal csc, its included with it.
If you used twrp recovery etc to flash unofficial oreo releases, you need to first confirm if oem unlock is enabled, don't tick on auto reboot option, just tick F.reset from odin options, then first flash latest nougat for your region through odin, then flash twrp through odin. Then when odin says pass, force reboot into twrp recovery from download mode, then format data in twrp and flash super SU/magisk and no verity opt encrypt. Then reboot and you will be good.

can't downgrade
odin gives "FAIL" when starting the procedure.
i have the U1 nougat version and the U2 oreo version.
can't seem to find U2 nougat ( if any) and I guess upon upgrading to OREO sonething had changed and can't downgrade anymore.
I managed to get into android recovery and did a factory reset and total wipe but nothing, through ODIN flashing doesn't work.
Any ideas anybody ? I really want to downgrade so I will be able to install stock nougat, and flash an oreo custom ROM with magisk in order to get around the KNOX triger thing.

You can't flash U1 nougat on U2 oreo firmware. It has been all over xda that U2 firmwares has Version 2 bootloader which can't be downgraded to Version 1 bootloader of U1 firmwares. Nougat has many U2 firmwares, you simply need to search..

bluetooth start works but need switch off battery optimization
Hello everyone
I found it!!!
Problem with your bluetooh connection after upgrade can be solved in one of the way follow previous post or "disable battery optimization.
I try before swichng off and on all networks, emergency mode etc. and nothing happen.
Disable battery optimization
Sometimes battery optimization also messes up with Bluetooth connections. I suggest you check battery optimization settings and remove Bluetooth from it. To do so, follow the steps:
Open device Settings and go to Battery. There is few ways to go there:
first can be: open settings go to "device maintenance">>>clik on "battery">>>clik on "batterry usage">>>clik on 3 dots right top corner>>>then clik "optimise battery usage">>> and u are there - swich off “Bluetooth MIDI service” and apps that you use with Bluetooth such as Play Music, Phone, youtube, maps etc.
2nd
open settings Tap the 3-dot menu present at the top right corner and select “Battery Optimization”.
Turn off Battery Optimization for “Bluetooth MIDI service” and the apps that you use with Bluetooth such as Play Music, Phone, youtube, maps etc.
