How to downgrade android 8 to 7.1.1 - Samsung Galaxy Note 8 Questions and Answers

successfully ..close

Are the pictures that bad? Both cameras? I do not think oreo has something to do with it, the forum would be flooded with the issue, it must be something else, check carefully

Yes, i think so, because i often take picture so i find some diffrent between android 8.0 and 7.1.1.. Dual camera often has noise.

You should be able to flash back to Nougat no problem as long as you flash Nougat FW with v3 bootloader.

Yes, BRA8 should work. I haven't tried for myself as I don't want to install Oreo yet but in the past I have "downgraded" fine as long as bootloader version is the same. I have seen others going back to Noguat from Oreo so it is possible.

Oh, now that I really don't know. OEM lock shouldn't matter whether off or on. You should be able to flash stock FW without OEM unlock on. If it's on then it should definitely work. Worse that will happen is it won't flash so it won't hurt to try.
Now whether you will loose OEM after flashing back to Noguat I don't know. I rarely flash in Odin, I only use Odin to flash TWRP, after that I do on my flashing in TWRP. My phone doesn't suffer from the 7 day thing so I don't have any experience with loosing OEM.

Ah I see. Just try with it off. I don't think you need it on to flash official firmware. But I know I have flashed official firmware fine with it on. I haven't turned it off since I first turned it on the day I got my phone.

Yes v3 to v2 will fail no matter what regardless if oem is on. Can't downgrade bootloader.

I flashed back 7.1.1 successfully, but I flashed back to combination firmware first, then flashed to 7.1.1

Download COMBINATION_FA71_N950FXXU3ARA5_CL12991683_QB16751804_REV00_user_mid_noship.tar.md5
Search here or google,
Flash to this rom,
Then flash to your 7.1.1
Or just try to flash to 7.1.1 directly, should works because it's not test firmware, you are allowed to flash back to 7.1.1

OEM Unlock can be on or off when you use odin to flash firmware. It doesn't matter either way. OEM Unlock is only when flashing custom stuff.
You really should not need to use Combination Firmware when downgrading from OREO to NOUGAT as long as you are using the right bootloader. BRA8 I thnk is the is the most recent NOUGAT and you can just flash that bootloader and you should be fine. I did it and it wasn't a problem.

No there is no hardbrick . If you are not on the right bootloader and modem the rom may not boot , so you just flash the right ones.
If you want to came back to LP flash lollipop last booloader and modem and you are ready to go.
Basically , bootloader allows you to boot the rom , modem is everything related to signal , wifi...etc if you are in the wrong one you will not have signal or some things working

Yes, you can. First backup your android 6.0.1 from your recovery, in case something go wrong, you can go back.
Won't flashing/ downgrading the bootloader brick the phone ? How do you flash the LP bootloader and modem?Please can you give a step by step guide and where the correct files can be found? Thanks

That's never happened to me before. Did you flash an incorrect model bootloader?
What model Note 8 do you have & exactly what files did you flash? I'm confused by your post, did you get it working or did you still need help to get it working?
And you should change the thread title. TWRP has nothing to do with your sensors not working.

What bootloader were you on before? Were you on Nougat or Oreo before flashing Weta? What version Weta rom did you flash & did you flash Weta bootloader & modem update?
I've been using Weta rom for a long time & never had this issue so I still think it's a bootloader issue or a coincidence that your phone's hardware failed.

Since you won't say what Weta version you flashed & you didn't flash Weta bootloader update, I'm assuming you flashed Oreo version of Weta as Weta rom itself doesn't include bootloader & modem.
Since you won't give more details on what you flashed exactly I don't have a clue on what you should do or if it is a bootloader issue. Maybe kernel related I don't know.
So at this point all I can suggest is that if you are on BRA8 now, flash entire BRA8 or BRB2 firmware in Odin, BL, CP, AP, & CSC. Or at the least flash BL & CP.

Not if you flash only BL & CP. But those won't flash kernel. If you still have the issue, trying flashing a custom kernel if you don't want to loose TWRP & reinstall.
First off, I feel there would be many more reports of this with either TWRP or Weta Mod if the issue lay there with either of them.
I have used both in the past and have always worked fine for me.
Did you follow the flashing instructions letter by letter?
Have you got the latest TWRP that works with Oreo?
Which I believe you need to flash the older version before flashing the newer TWRP via TWRP with the iso.image?
I would just flash the full stock image via Odin like others have suggested. If the phone then works fine, as it should after this, try again but just take your time doing it.

Bought a XT1926-8 yesterday and apparently its impossible to unlock the bootloader

just updated to the newest OTA version(1 june patch) and Oem unlocking is available now, thanks everyone.

How is OP supposed to flash it? bootloader needs to be unlocked doesn't it? He says he's having trouble with the OEM unlock. Bootloader, then custom recovery, then you can flash roms, or am I wrong?

You should flash the firmware from your phone, in this case if i'ts G6 Plus, It's EVERT, it's here on the forum.

For flashing custom recovery and custom Rom, you need unlocked bootloader, for flashing STOCK system you don't need it to be unlocked

Hi Techno,
How exactly did you do it? it's been so long since i used to play with rooting phones. and i found one phone that made me wanna root. Moto E4 plus. after all the steps, now am stucked to TWRP. i tried to flash magisk but still goes back to twrp.
TWRP: twrp-3.2.3-0-nicklaus
instead of: twrp-3.2.3-1-nicklaus, issue file too large
i'm not trying to revert back to original, im still pushing to root the phone. but, im stucked.
what could i possibly have done wrong?
Thanks in advance!

All versions of EMUI10 that I've tested so far, force locks bootloader. So don't install if you don't want to get locked. I guess if you have beta access approved you can downgrade back to 9.1 using HiSuite.
I have to downgrade using testpoint
Fastboot will still say you're unlocked but the command fastboot oem lock-state info says it's locked. Downgrading back to 9.1 will give back the unlock status, apparently. I guess they just add something to lock even if you're technically still unlocked. And the command to unlock through fastboot is removed so no way to unlock it again. I hope it's just locking for the beta.

Like @ante0 said in the previous post, we already have the links for the updates, but so far all of them will trigger the bootloader lock, so unless you don't care about it, you should refrain from flashing EMUI10.
If the final release won't change this behavior, then probably Huawei has decided to lock the bootloader for good.

Downgrade to EMUI 8?
Well, if you do like me you have to as I have to flash board when BL is locked.
If you mean to keep unlock it won't work. Update from Oreo to Q directly will cause problems, it did for me when going Oreo to 9.1 anyway, and system update actually forces you to flash the latest stable 9.0 (9.0.0.197) to update to 9.1.0.300 then to 9.1.0.306.
And it's not like it's using a function to lock BL like they do when you flash a dload firmware. It's probably still unlocked but something changes it to locked. Iirc you could unlock using TP before, but now it refuses as USERLOCK is changed to unlock as well when you use testpoint, so it will just say "Phone is already unlocked", before it only changed FBLOCK to unlock.
But we will see what happens
@ante0 @Pretoriano80 : just in case I would install this beta from FF. What install method I have to use?

Installing with no-check recovery should work just fine, but you should also flash the new CUST and Preload.
If you really want to flash it, i can send you the link with the latest build (B140), but like i said, it will lock your bootloader.

You can use the 3 files tool (skip the rooting part, of course) from here -> https://forum.xda-developers.com/mate-10/how-to/tool-emui-9-0-to-9-1-upgrade-tool-t3949867 <- and replace the nocheck.img with the one from here (tge no verification version) - > https://forum.xda-developers.com/mate-10/development/recovery-nocheck-pie-t3950037
Make sure that the downloaded firmwares are not corrupt, otherwise the installation may fail, because the no-check recovery will skip the integrity check.
I will send you the update files in PM.
i'd like to have a link for the update files aswell please, on firmware finder PC version there's only 10.0.139

It doesn't really matter. When you flash it you won't be able to flash any newer ones as you won't be unlocked anymore, and can't unlock again either without downgrading back to 9.1.
I would wait until official to see if forced locking remains or not.
