How to get back to stock based roms from Oreo? - LeEco Le Pro3 Questions & Answers

I am currently using the oreo roms(lineage,aicp and etc..), but I would like to get back to the stock based twrp roms like genesys and the other ones. The problem is that when I flash them via twrp, the phone boots and shows an error: encryption unsuccessful.

Hi,

Thanks it worked

Just as a sub question, how to avoid encryption on Oreo ROMs?

you cant, the latest twrp the one with 3 2.1.1 encrypts the phone and it can be used only on oreo. if you want to go back to nougat or less you have to wipe all internal storage with all in one tool.

Remember abt backing up all photos, videos or your personal files in internal storage.

[URGENT] Unable to boot after modifying build.prop

Hello,
I was modifying build.prop, had made a backup and saved it in another folder in my phone, after modifying, I think it's because I've forgotten to set permissions or something, now I'm unable to bootup after rebooting.
Any idea how do I solve this? I've read online something about adp or something, but I've totally no clue about these.
Is there anyone who has a solution to this?
With sincerity

If you did a backup and have TWRP, just delete the old build.prop in /system, move the backup there and set permissions. ;

System, data, internal sd, cache, what did you wipe? If you:
1. Wiped data/system :- you can only flash a new rom since you don't know ADB. Or flash stock via odin.
2. Internal sd :- that's it, flash stock firmware via odin.

Either reflash your custom ROM via TWRP (dirty flash and it'll keep your data etc) or do a stock flash via ODIN and start again. Can't remember if you can use ADB to restore your build.prop been an age since I used an N3.

My computer doesn't have my device in device manager when I've connected it, was unable to try using ADB earlier when I've tried, any idea why?
Anyway, can you direct me to a guide way I can do a stock flash via ODIN? I'm seeing so many threads in this forum but I've no idea which one is suitable for my phone.
Thanks!!

If you were using stock then you'll need to have a read around general and learn how to flash with ODIN. It's pretty straight forward, you can grab official ROMs from either here on XDA or Sam mobile/firmware. The link escapes my mind currently.
If you were using a custom ROM, download to your PC and use ADB Side load or download to your External SD Card and flash via recovery.
You can use THIS for ADB drivers, it's 15second ADB install and it should work for you.

Weird, computer won't have my phone's device show up...
EDIT:
In the development section, I see lots of roms, any idea which one should I download? I just want one which I can flash to and get my phone working again.
Thank you! I'm on SN-N9005 btw!
Can I contact you via skype or something btw?

For Stock you'll need the ROM for your region, this is quite important otherwise it causes headaches. For custom, it's entirely up to you, you can choose any TouchWiz based (stock look and feel - I personally recommend AllianceROM by @sparky b for TW based) Or AOSP based (Pure Android with no Samsung features - Temasek's ROM is stellar in this department and the new OMNIROM for the Note 3 will be superb once the dev has it sorted 100%, it's still being debugged and beta tested currently and dev tree's etc redone, stop by @jakew02's thread and have a read at where he is up to)
If you have the N9005 you'll be OK to use any custom ROM for that device. Just stay away from the Exynos (N900) ROMs as they won't work and will brick your phone.
I've recommended a couple of ROMs which are both Stable and feature filled plus one which will be great once fully flying. Other ROMs in the development section are just as great, however, I can only comment on the two I used solidly when I had my Note, and the one's I have ran on other devices. But ultimately it's your choice.

Partition internal memory to retain data after new rom?

Hi
Is it possible to partition the 64gb memory such that my data is retained after every new rom installation?
I came from note 2 and was very confident when formatting the mobile as i can take the sd card out before doing any experiments, but on Nexus 6P i have lost data 3 times as the rom. Was encrypted and custom recovery doesn't enter without formatting user data.
If partitioning is possible please help me.

You do know if you remove the security pin/finger print that twrp will be able to backup and restore data?
If I'm not mistaken they've also released a new twrp that allows decryption.
Keep in mind that ROMs of different bases may not boot without wiping. Quite honestly since Google's restore function has gotten better I haven't had the need to keep data. Everything from my home screen layout to my app data gets restored after a flash.

Is the answer 'NO' to the partitioning of internal memory?

How are you producing this issue? What is your setup? This sounds like you're either using an older version of TWRP or N developer preview. For N Developer Previews, you must be and stay decrypted to use TWRP. Format userdata then install a modified boot.img to remain decrypted. The stock boot forces encryption.

I am using latest TWRP (version 3.x.x.x) with N Preview 3. Diasbled all securities.
rebooted into bootloader and installed TWRP, rebooted to Recovery. Stuck at splash.
Took backup of internal memory and installed modified Boot and now working fine.
taking a backup and restoring takes hours for some reason.

Ok. To flash a Marshmallow rom, I believe you need to just flash the matching OS' vendor.img before booting into the Marshmallow rom. Make sure to do your factory reset and system wipe like usual.
If you intend to use N previews each month, you'll likely have to stay decrypted. I do not see a reason for the TWRP team to officially support Android N until it's official release.

I am not blaming anyone. but was only curious if partitioning internal memory was possible. I remember changing the partition tables on Nexus One.

Oh, I wasn't implying that. Hope you don't take it that way. I just meant, if you plan on using N previews, unfortunately this scenario is not likely to change. Just wanted to help you resolve your issue with encryption, TWRP, and switching between Android MM/N.
I don't know about partitioning but maybe it is possible? Maybe someone else can chime with their experience?

Error 7 [TWRP]

Greetings gentlemen, well .. I suppose I want to install cm 14.1 unofficial on my OP2 A2005 but it happens that when I enter twrp as usual and perform all the previous steps and install the ROM as it gives me "error 7 and bla bla bla" I looked on the internet how to solve this but to do it and try again it gave me "error 4 bla bla".
I also read that installing a previous version of OOS (specifically 2.2.1) would be solved, tried and do not know what happened? Nothing, I still can not change the stock rom. Someone who happened to be similar and could have solved this situation? I really want to be able to change any rom

Tested but still not working
1)back up all your data to pc and try wiping everything(include internal storage) after that try to install recovery from fastboot and then try install whatever rom(oxygen for example)
2)or just delete twrp folder on internal storage and try if it helps
Flash oneplus2 oxygen 3.0 beta then flash latest TWRP then new rom that you want to use. That's what helped me fix the same problem.

Hello masters , There was issues with boot loop in my OP2, I got it fixed with OP Tech support help, they took control of my laptop installed Certificates and then flashed the latest version of OOS3.X.x
I unlocked the boot loader - successfully
Went to TWRP official site and downloaded the latest TWRP for OP2 and flashed via fastboot - successfully flashed , however I am unable to get into TWRP Recovery. It takes to the OP stock recovery. HELP if anyone has faced this issue before.

I think you actually can roll-back to MIUI normaly
I also would like to know this, i believe you can flash through TWRP but i'm not sure and i would like someone to confirm this because i need to do it today and i don't have a windows system to recover it with ease if something fails.
Thanks.

It's possible but you need to disable dm-verity in twrp (or flash lazyflasher) else it will not boot, and it will wipe your internal storage partition during installation so make sure to backup your data and place your rom in microsd rather than internal storage.
I think you better use xiaomi.eu rom rather than official, since it easier and not wiping your internal storage during installation.
Just flashed the official ROM through TWRP, disabled verify in the options just in case, threw some mount errors but installed correctly.
I just did it and it works fine.

custom ROM to stock OOS

I'm on a custom ROM based on 9.013.
I have the full ROM zip on my sdcard for 9.017. Am I able to flash it via TWRP recovery to get to a stock OOS pie ROM?
Unfortunately I haven't been able to find the answer whether it's flashable via recovery or not.
Thanks,
Pain

Yes of course you can flash oos via twrp. Just make sure it's really is the Full zip AKA over 1+ gig file.

If going from custom rom back to stock oos, don't forget to format data in twrp. Do a backup first because this will wipe everything. So do like this.
Reboot to twrp
Flash oos followed by twrp installer tap
Wipe them select format data type yes
Reboot recovery and install oos again followed by twrp installer again
Reboot recovery and flash magisk then reboot to system. Good luck.
