Hi, im new to Note 5 Dev. and been out of the loop since it was released. i had a Sony Xperia play and a Galaxy s3 before and know how to do the basic stuff to do custom roms and flash stuff etc. to those Phones. But a Note 5 is different, running on Lollipop, having EFS partition stuff and OEM unlock Stuff. i just want to ask a few questions to make sure i don't do something stupid (i already did some of the research for answers on some of this for a few days now and some are Informative and Awesome, but a little outdated) so tnx in advance kind People :fingers-crossed:
My Device: SM-N920C (UAE)
Android Ver: 5.1.1 (Lollipop) Stock
Questions:
1.) Can i Revert back to 5.1.1 (lollipop) stock/ [Downgrade] , IF i decided to update to Nougat Stock?? (just curious ) and if yes, can you kindly link me to a process? if not, then that's fine too :laugh:
2.) Do you have to Enable OEM unlock if Updating Stock (in my case Nougat)??
I red somewhere on Magisk thread here on XDA that it can Grant Root Access to 5.0+ . If so, installing TWRP and Flashing Magisk on 5.1.1 involves Enabling USB Debugging and OEM Unlock.
3.) Do i have to Enable OEM Unlock Forever now? cause i saw some threads says that if you disable it, you will have a bootloop or a soft brick and will have to Flash Stock again and repeat. (don't really have a problem with it being Enabled, but the other people in Tutorials , Vid. Tutorials and Thread Posts just mentions "Enable it". And never really says after the process is done u can Disable it and stuff.), just want to have that information, cause i Understand that OEM is a LOCK that Even if someone steals your phone and has a lock in it. they can't just Flash a Stock Rom on it to Unlock it. [great feature] :fingers-crossed:
4.) if i have a Custom Recovery and Rooted my phone ver. 5.1.1 successfully, can i still Unroot it and go back to Stock 5.1.1?? also applies to other Versions of android. EX. nougat Stock then i root it, will i still unroot it and go back to stock?
5.) Do you need to be in a Specific Version of android to use the Custom Roms?? i mean i'm in android 5.1.1 [if rooted], can i flash a Nougat Custom Rom or a s8 port etc.?? or do i need to be in Stock Nougat > Root it > then flash Custom Nougat Roms?
That is all, Sorry if all the Questions are Freakin Long Shahaha, i just want to be specific so all the people who are also newbies can understand the questions and have answers. Tnx again for the people who have the patience to read and answer these questions. :highfive:

1)If you flash stock 7.0 on your device if available then its hard to revert to back to stock 5.1.1 as there is thread in Question&Answers section about downgrading from 6.0.1 to 5.1.1 but many are unsuccessful(I have successfully downgraded from 7.0 to 6.0.1 but Cant confirm about 5.1.1 as google has changed many security policies in updates versions like 6.0.1 or 7.0 which will block your bootloader to downgrade easily/Issue you will face like lossing of baseband or corrupt imei which will block you from receiving network signal)
2)Yes its very important to enable Oem unlock and usb debugging while flashing any stock firmware using odin to avoid DM-Verity/SW Check Fail/Custom Binary blocked by FRP like issues which are hard to solve enough OR you will might hard brick your device which will be difficult to make it live again( AFAIK to flash TWRP or Any root access using odin there is instruction to enable Oem Unlock before flashing always remember it as a essential step before flashing anything using odin)
3)Yes once you enable Oem unlock for purpose of modification of your device, it needs to be unlocked or even its enabled by default to overcome reported issue like infinite bootloop or Many i mentioned in my 2nd Post And Oem unlock allows your bootloader to be customised by flashing mods or roms which is by default locked so that you could not easily modify your device as well as to avoid further modification issues
4)If you choose to stay at 5.1.1 and rooted your device with installed TWRP then yes you can unroot it by flashing 5.1.1 using odin( In case your on 6.0.1 or Even on 7.0 you can unroot your device with the same process but here to remind you that you need to flash stock 6.0.1 or 7.0 respectively version on which you rooted your device So if you will try to unroot it by flashing 5.1.1 again while your on 7.0 rooted device then again here downgrade issue which will probably give you mentioned error as a result)
5)To use custom nougat based roms or any S8+ port based on 7.0 you should atleast upgrade your bootloader and modem to 6.0.1( If your rooted on 5.1.1 and try installing nougat roms then your device will not boot as your using old bootloader, so upgrade bootloader or modem either to 6.0.1 or you can update whole system to 7.0>root>install TWRP>flash custom nougat based roms or s8+ ports afterall choice is your as if you want to upgrade only BL and Modem to 6.0.1 or want to upgrade system with BL and Modem to 7.0, i will mention here is BL and Modem for 7.0 are also available to flash you can find those on dr.ketan rom n10 installation instruction section in Samsung galaxy note 5>Android development>Dr.ketan Rom N10 instead of whole system update but Flashing Stock full firmware is always recommended for good reception and avoid glitches)
I think i have tried to fulfil all of your queries as far possible by myself

Too bad about the answer to the 3rd question, that feature would've been nice to have. but oh well. shahahaha
~Ooh!! i have a follow up question regarding your Answer to the 4th question. Can i also flash other Countries Stock firmware?? for example: mine is Stock 5.1.1 [UAE] can i flash Stock 5.1.1 [USA] or other Country variants?? [of course unlocked bootloader] , i searched again here for people who did that and for some reason they encounter Errors and Unable to revert back to their Original Stock Firmwares.
@AssassinCreed Thank you. yup, clear cut answers. Thank you!! :victory: :victory:
Sorry for my noobish question, but i just buy today an old stock rom P9 and want to make a complete custom and I read much but want to be sure about 2 or 3 things
I have read about unbranded phone, how can I know that
is the procedure to root and install TWRP is the same with my firmware and 6.0 rom, because I find a lot of tutorial about 6.0 root but none for 7.0
if yes, I have to unlock bootloader, root and install TWRp and that'it???
that's my first Huawei and I'm on Samsung since too much time
thank's for the help
It's seem that 7.0 rom have big drain...Is 6.0 is less drain or have I to install different kernel to solve it????
I done it before on s9+ but i have read on some sites, that bootloader must be the same, my bootloader has the '7' bootloader but want to run a Oreo rom (exykings oreo light rom) can i just flash after clean flash, or is it not possible?
Thank you

Not possible, you already answered yourself because you know you can't downgrade the bootloader and you can't run Oreo using the Pie bootloader.. If you're on an F version of the phone then you should be able to flash twrp and then flash whatever you want I'm assuming.

If you want to downgrade from Pie - N950FXXS"7"DSG1 to Oreo - N950FXXS"6"DRE2 you CANNOT do it because the bootloader ver "7" won't allow itself to be downgraded to lower versions "6",5,4,3,2, and 1! You're stuck on PIE!
(The Number in Quotes is the bootloader version. )
If you root your phone you can try to see if the custom oreo rom will boot with bootloader version "7" by asking and searching in the custom rom (that you choose to run) thread.
Root does come with a few cons like permanently tripped knox, No Samsung pay, and no knox related apps so read up on it.
(You will lose secure folder and Samsung health if you go back to stock firmware! But if you stay rooted and on a custom rom then you'll have access to Samsung health and secure folder (Devs found a way to get secure folder working! Check the note 8 roms forums for info on it.)

Read @BluePhnx post.. I already told you that you can't downgrade but you can root and flash twrp and then flash whatever roms that the devs have made for bootloader version 7! There's really no going back!
Successfully unlocked PRA-LX2 bootloader with DC Unlocker
Flashed EliteTWRP (because every other TWRP is down)
Rooted with Magisk
But
There are no ROMs that says it will work with EMUI 5 PRA-LX2. Tried LineageOS that said will work with EMUI 8.x firmware and obviously didn't work.
Can't update to EMUI 8 through Team MT because it only supports locked devices?
Manual EMUI updates get stuck at 5%
Phone doesn't even show a updater app
Does this mean i'm stuck with unlocked emui 5?
Can someone please link me to a guide that will help me update to emui 8 and oreo manually so i can enjoy these awesome ROMs?
Please
Okay Haky86's LineageOs 14.1 worked but I still need a way to update that to newer LineageOS version? Anyone have a guide to dload PRA-LX2 to EMUI 8?

Did you tried updating via Hisuit ( PC software) ?
---------- Post added at 05:57 PM ---------- Previous post was at 05:51 PM ----------
If Hisuit method doesn't work ...
Try this
https://forum.xda-developers.com/p8lite/general/hwota-huawei-p8-lite-honor-8-lite-t3777058
I haven't tried this ... Because my device updated via OTA

Nope it won't work
All roms available for this device are GSI's ( Treble roms).
What you have Now( Lineage OS 14.1) is not GSI rom
Your device will be treble supported after updating to EMUI 8. After that you can Flash any rom of your choice.
Currently I have Havoc OS 2.9, it wasn't available on these treads but I Flashed it because it was GSI rom

I followed this guide
But the TWRP mentioned in the video didn't worked for me and No official TWRP was available for this device at that time.
After Flashing System, I did Factory reset via Stock recovery.
About Performance ... Don't expect Mid-Ranger King like performance ? UI animation seems a little slow than AOSP Stock Roms. You should also Flash NSF- Injector or L-Speed or FDE.AI like Magisk Modules Why? Because these optimize the Rom and I was able to play Call of Duty Mobile on Medium Settings?? on EMUI 8 it was struggling even on Low settings.
And I have Stock Kernel
Rom is stable ... Bluetooth Audio work. Adaptable Storage doesn't work and I heard it doesn't work on Android 9. Didn't checked the GPS.
Update ...
Things I forgot to mention ...
1) Signal bar is bugged it always shows 1 bar?
2) Camera is now choppy ... P20 pro camera Magisk version doesn't work, Gcam doesn't work because of Android 9?but you can have Google Camera Go, result is better than AOSP camera
3) Mobile Hotspot doesn't turn off, you have to Enable WiFi to turn it off???

Important Note :
*DC unlocker doesn't Unlock the Bootloader* .... * it only gives you the Bootloader Unlock Code* .... * So you have select "get bootloader unlock code" NOT UNLOCK BOOTLOADER ( currently I don't remember the correct option on DC unlocker Client)
Firstly I downgraded to Android 7 via Hisuit, then Unlocked the Bootloader. At that time DC Unlocker worked only with EMUI 5 ( Android 7), I don't know about the current status of DC unlocker. If you try to get bootloader unlock code with Android 8 it won't recognize your device.
Updated to Android 8 via OTA to enable Project Treble
Brother Momin, which version of TWRP did you use? My phone has EMUI 8 and I have unlocked the bootloader.
I had tried following the video you mentioned above. I used the TWRP they mentioned. Then downloaded Havoc 64bit ROM and flashed it. The everything went downhill from there. I couldn't factory reset or boot up. Sadly, I forgot to make a backup and then had to get my phone flashed with the stock ROM from a professional. What was the exact steps you followed? Thanks.

I had major problems too when I wanted to boot HAVOC OS 2.9
I used this guide to unbrick mine
https://forum.xda-developers.com/p8...uide-brick-huawei-p8-lite-2017-maybe-t3816694
In this guide there is TWRP named RecoveryV2 ... This was the only working TWRP for my device,
https://drive.google.com/file/d/190zqju8ZmwZCzI4WXtujgKLFXvvuWTk8/view
*important Note* = I could use this TWRP to flash things like Magisk,OpenGapps or to revert to EMUI etc. This TWRP couldn't Factory Reset my device and corrupted my internal Storage.
You have to wipe system via fastboot, Flash Havoc OS via Fastboot , Factory Reset via Stock Recovery ? then Flash TWRP to flash Gapps, Factory Reset via Stock recovery ? Flash TWRP for Magisk?
In Magisk you should Flash Ainur Auido to increase Sound Quality and NFS Injector to increase the performance of Device
Its been a year since I Flashed Havoc on my device and I kinda Flash and Forget ?
Thanks for the reply. Your device is Pra-Lx2 or Lx1? Is it your daily driver? So the process is: bootloader unlock>wipe system via fastboot>flash havoc>factory reset via erecovery>flash twrp,gapps, magisk etc.
Will I be able to backup my stock rom from twrp before I flash Havoc, as a fall-back if anything goes wrong?

My device is Honor 8 lite (PRA-LA1)
TWRP couldn't do Nandroid backup. I haven't tried Official TWRP because I didn't need it.
Yes Havoc is daily driver.
If anything goes wrong,follow unbrick guide- unbrick via HuruUpdater method. Always have full Stock Rom on your PC ( as it is around 2.5gb) you can get it from Firmware Finder.
After Gapps I did Factory Reset via Stock recovery just in case?
