Hello,
this is the very first time here at XDA Developers Forum that I do not find clear information about rooting a smartphone. I am talking about this Nokia 3 updated with OREO 8.0. Only a lot of confusion reading your posts, sirs. Nobody that is telling if rooting this model is possibile or not. So... can anyone says if it is possibile and how to do that, in a clear and simple manner?
Thanks and regards!

this thread should be on Q&A.
Hello,
thanks for your reply. I already read this thread.
So since I am on OREO, it seems I have firstly to downgrade to Nougat. Can someone please tell me how to do that, posting links to the official 7.0 rom, the software and a short guide? Somewhere I read you have to use OST, somewhere else SP Flash Tool...
Thanks in advance and regards

Hello again...
I am trying to downgrade my Nokia 3 8.0 to Nougat, in order to unlock the bootloader.
I have searched a lot for an official 7.0 rom... nothing official... I tryed to follow this guide:
https://forum.xda-developers.com/nokia-3/development/nokia-3-official-firmware-india-uae-t3674320
Managed to install and get a working copy of OST. Connected and start flashing the rom NE1-147I-ind-0-00WW-B02.nb0 (the one I thought it was the earlier one, since nobody wrote "7, 8, or another number" in the file name). OST got stuck at "Reflash service bootloader..."
Can anyone please write a clear guide on how to proceed to root a Nokia 3 OREO that was never ever unlocked before (i mean with bootload never unlocked)? I am going crazy, really...

flash UAE version of nb0 if IND doesn't flash, that's Android 7.0 May 2017 Security Patch, unlock and lock bootloader there and apply OTA updates from notification up to latest update. Then follow guide.

oh they deleted it it was before. I have it on PC, but PC can't turn on.
I have found the file elsewhere... NE1-147C-UAE-0-00WW-B01.nb0

which ost la version you have?
I finally managed to downgrade to Nougat 7.0.
Now, in order to get root, do I have to unlock bootloader first? Can I obtain the code only via a request to the_laser (that didn't answer me) or can I use an online tool ?

you need to unlock bootloader first, and you can PM code i will send you key, use only OTA through notification, don't use OST LA for this guide.

Hi,
can u tell me the method in which you downgraded Nokia 3 from 8.0 to 7, also were u able to unlock the boot loader and root the device. Waiting for your reply as one of my friend also wanna do the same.
Short question: how can I downgrade or FRP unlock a S8+ G955F that is FRP locked and on very recent firmware?
Here are the details:
I am trying to assist a family member with a Galaxy S8+ (SM-G955F) that they have just purchased online. When purchasing it they were not told that FRP lock is on (FRP LOCK: ON) and OEM lock is on (OEM LOCK: ON). It was running Bootloader v2 on very recent stock firmware. It has been successfully flashed with BL_G955FXXU2CRED and AP_G955FXXU2CRED...
It was on G955FXXU2CRED firmware. I was able to successfully able to flash the Combination ROM COMBINATION_FA70_G955FXXU2ARE1 (full name COMBINATION_FA70_G955FXXU2ARE1_CL12792727_QB18097821_REV00_user_mid_noship.tar)
With combination rom, it seemed that I could enable USB Debugging, and also follow the steps for *#0808# IME to enable the appropriate mode for adb codes to be entered. I was able to find the device with 'adb devices', and I thought that the FRP unlock codes on the command line worked. But after re-flashing to the current Stock Firmware again, FRP lock was still there.
It seems I need to downgrade to Nougat 7.0, but I am on Bootloader V2. Odin identifies it by a FAIL with binary not matched (2 vs 1). So it seems that if I could get a method to keep Bootloader V2 and install Stock Firmware for Android 7.0 Nougat, I would be halfway there to fixing the FRP problem. However, I can't find any firmware or ROMs for G955F that includes Bootloader V2. This is identified by a U2 in the firmware name, like: G955FXXU2CRED . Is there a way to keep the BL Bootloader V2 but install AP ROM from Nougat?
I have spent many hours on this so far, and I just wanted to say thank you to all you guys who are helping on XDA, I really appreciate it. I have read about 7 day waiting periods for OEM UNLOCK but I don't see how it applies, as I can't do anything aside from use Combination ROM, use Odin, or go to the FRP locked FW which seems to be a dead end?
If there was a reliable method for rooting this G955F device with this G955FXXU2CRED firmware, I would be open to trying it.

Another note: AP SW Rev is identified as B:2 K:1 S:1
I don't think once a phone has the boot loader CRED, that the phone can be downgraded. Hope I am wrong.

I think you are right. The combination ROM seems to built on selinux version 7.
I think I need to root with twrp. But first I need to enable OEM unlock. I'm not sure if that will be possible with combination ROM or if I should flash latest stock and then wait 7 days??
same problem here... If an solution available pls write here

Flashing stock rom and waiting 7 days would be the safe option.
I am not exactly sure what you are trying to achieve.

I think I read someone on CarHDRom who flashed the rom via TWRP, and then when the phone booted into system for the first time at setting up, they changed the date to 8 days earlier, and when the phone setup was completed and booted into system, the OEM unlock was available.
Re: CRED I believe once it has been installed on a phone, you can not go back to a previous version (pre CRED).

It seems there are a few solutions to frp if you can selectively restore flash files. It looks like Samsung tool Pro can do this, but is there any free adb method?

I still can't get this to work. Have you purchased Samsung tool Pro to do the flashing of individual boot files? What version?
Hi there. I already bypassed the frp.. If you need. Hp with android 8.0 even with the binary 2. I have some comb files and working stock roms through odin. Feel free to pm me via my email [email protected]. Thanks!

Download latest odin and try again. I too got stuck in similar situation. Realised the issue is due to Odin. If you are using latest and encountered this error, try one version earlier.
I too can confirm that the combination-ROM works like a charm with odin. FRP kinda unlocked itself
I know this should be in Rom,kernels,rev. I'm a junior member so I can't post their yet
So I've recently rooted my phone. I got too excited and tried installing a custom boot animation that screwed up my phone and it couldn't shut down only restart.
Then I had an idea to wipe the system through TWRP and I accidentally deleted everything (Wiped internal storage) so download mode was blank. Then I tried installing stock Rom but I extracted it, removed the stock recovery.img.lz4 and replaced it with the TWRP Recovery. For some weird reason the firmware was acting weird with T mobile roaming and stuff that wasn't supposed to be there cause I'm not a t mobile customer. Then I just flashed stock Rom (Augaust security patch) with Odin. Aaand I got RMM Locked again :crying::crying:
I thought flashing combination firmware again would allow me to access the OEM unlock option and flash TWRP again.
When I tried to flash I got an error SW rev check fails device 3 binary 2. If anyone could help me I would really appreciate it. Also if anyone knows why I got the T mobile stuff after I did the TWRP thing (out of curiosity) I would like to know. Please respond.

It seems that your filmware is corrupt.
Which bootloader binary are you on, binary 2 or 3, Nougat or Oreo?
Remember that if you have binary 3 you cannot downgrade to binary 2.
And don't use the combination rom anymore because you have to know what you're doing its risky.
I can advise you to do a fresh install of the official country filmware from out of the box, and after that update to the latest filmware version, and a big chance to get rid of RMM prenormal state, with oem-unlock back.
If you're on binary 2, just flash an official filmware from your country before the August security patch, after that update it again to the latest version.

What I meant is the first official filmware you had when the phone was bought,and if you were on binary 2, but that doesn't matter now you're on binary 3.
Now you have to flash the official filmware from your country, it must be a binary 3 filmware because downgrading will not work.
After that you have to do jailtime for 168 hours untill oem unlock is gonna appear again.
Do not restart the phone or disconnect the network at this time.

Unfortunately you do with the 1 august patch, if you can find a previous official filmware, for example april, may, june or juli patch you can do the trick to set back the date and time 7 days and get oem unlock back.
But this does not work anymore with the august patch or later, that means you have to wait 7 days.

At this time its impossible to downgrade from a binary 3 towards 2 or from 2 to 1.
You can only upgrade, Samsung has blocked the downgrading from a higher to a lower binary, therefore it is useless to try it with Odin, it won't succeed.
Maybe someone else knows a way around to downgrade, but I don't.

1. You didn't posted in the wrong section. This one is the correct one, the one where you wanted to post is reserved to ROMs, kernels and other projects.
2. Modifying Official firmwares is a bad idea if you don't know how to do it. Seems also you downloaded the wrong firmware for your phone.
3. Flashing Combination firmware is useless since OEM Toggle is still enabled (you said you were rooted so I suppose yes). RMM flag is still stored in RPMB and doesn't gets resetted by flashing that factory fw, to set RMM back to Normal you need to flash the full stock firmware for your country and wait the classic 168h countdown.
4. The "SW REV. CHECK FAIL (BOOTLOADER) DEVICE: x, BINARY: x" is caused because you're trying to flash a firmware with a lower rev. than the one installed in your phone. You need to flash a firmware with the same or higher rev (In this case, you need a XXU3/XXS3 or higher fw). Forget to flash a fw with a lower rev since RP fuse prevents you to do it (if you force install the bl via TWRP you get an hardbrick)

Already replied: no. First, there's no relation between bootloader and system (why should a wipe let you flash a lower rev bootloader lol). And as I already explained, Rollback Prevention fuse avoids you to do that: in Odin if you try to flash a lower rev bin it returns an error. If you try to force install it via TWRP, you'll hard brick your device and get a dead phone

both are sm-a530w both on oreo. binary 2 and 3

Greetings, ever since i tried rooting my phone, i knew something went wrong (i used cf autoroot).
So the first thing i noticed, i was asked to reset the phone or something similar to that, meaning i would lose all my data.
I tried to find a workaround as this had never happened to me before while rooting a phone, and someone had said that i was supposed to download twrp
and change some partition and then change it back. I dont remember what else he mentioned and what exactly i tried doing, i realised it was formatted either way and i had to start fresh. As i setup my phone i went and switched the oem unlock back to "off", as i did not wanna attempt to root again, but i hadn't realised that my phone was infact rooted sucessfully, leading me to my first error after restarting. "Custom binary blocked by frp lock", with absolutely no access to recovery mode at all anymore. Again, trying to find a workaround, i download some stockfirmware that i atleast had hoped was the right one for my phone, after a couple failed attempts of flashing with odin, ( i had gotten various different error messeges on download mode screen such as (REV Check fail device 7 binary 0 and others witch i cannot remember), now im getting a new error screen, stating that an error has occured while updating the device software. I cant flash twrp recovery as the frp lock is on, and the only thing i can guess is that im flashing the wrong firmware, but i cant find a matching code at all.
Its the following: sm-g930fzkadbt
IMEI: 35214310282955
on the back of the phone it says uk yateley, although the phone was purchased in germany.
Im not sure what to do anymore, any advice would be greatly appreciated.
PS: I have managed to get back to the old error screen with the custom binary info, this time with bootloop, by checking the deviceinfo box on odin
Yep you've now learned the hard way not to mess about and read the proper guides.
Anyway "dbt" is just unbranded german firmware. Download UK "BTU" and flash with Odin, it's UK unbranded.
FRP lock means you'll need to unlock the phone with the google account and password that was on it before you started messing about with it.
If you don't know the google email and password you need to read up on how to bypass FRP lock and it's a nightmare.

Thanks for your reply, just a question, will any btu update work? Should i download latest android version btu firmware?
(Also yes, it was stupid of me to try and do it quick but i had rooted 3 different samsung galaxy phones in the past without issues, either i did something wrong or it took something way too specific to do the job, perhaps the phone's unrootable, but thank you either way) :fingers-crossed:

You'll likely only find the last version of BTU think it was August 2019. It isn't updated officially anymore but it'll be fine to use.

OK so i thought it worked but i can only enter recovery mode now and download mode, but cant actually boot the system, it just boots up the battery screen whenever i plug the charger, and never shows the actual battery info, just the thunder icon. Formatting from recovery mode doesn't help either (Note whenever i launch recovery mode it says installing update, then says no command and brings me to the recovery menu) Any ideas?
PS: It fixed itself. Sorry for the pointless edit.
I want to flash TWRP onto my S8+ but im being blocked by the RMM. FRP and OEM is off but the RMM stays on prenormal. I have tried everything to my knowledge and what i have seen on XDA but no luck.
Is it even possible to bypass this?
My phone currently has the FEB 2020 security patch, is this a problem?
Please Help

Rmm/KG locks have been around since Oreo.
Generally to change KG and/or Rmm states takes 7 days ( 168hrs ) of ON Time with Internet Connection. Times may vary with devices.
While I have not tried them there are various threads on how to change the state.They may or may not work.
There are PC apps, like chimera, which also claim to be able to change the state.
I can't really recommend any one particular thread to try except for waiting for the time limit to expire. As I said some of the methods work for some but not others.
Flashing of stock firmware will reset these locks.
And only way to view these locks is in Download Mode.

The RMM state is now gone after the 168hrs as you said, which is awsome. I checked this morning. I unlocked the OEM and went to download mode, wasnt even showing. I'll try and flash TWRP later. I hope it doesnt gove me the "Official Binaries Only" error

I'm rmm locked here and need root. Are you sure flashing stock firmware will reset the locks?

Yes. Flashing stock firmware will relock OEM and KG and/or RMM state. Basically start the process again.
Note: Some phone can vary with times to be able to modify your phone. ie: my phone if I update firmware I can modify my phone as soon as I give it internet connection ( no sim ) using Wi-Fi.

Thanks for the clarification. I got locked after march security patch. I did all the stuff I found (date, reboots, etc) and nothing. I'll wait then.
