Hi there, I have my reasons, but I want to return back to a custom Oreo rom, I'm currently on a custom ROM with the latest firmware 9.0.7, so is it a case of downloading a earlier stock firmware, flashing in recovery? Also as I want to stay decrypted too, do I still use the v4 no Verity file on Oreo?
Thanks everyone
I am also thinking of going back to Oreo and have my reasons also. I think the best way would be to use the Aroma installer by brad which has oreo stock too.

would also be very interested if downgrade is possible. bought a used 5t with pie but need xposed and a few modules. anybody out there who tried downgrade?
Hi..I successfully downgraded my 5t to Oreo ob19 using flashable zip from below link
https://forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-mirrors-official-oxygen-os-t3708099
Copy the rom zip to internal storage. Reboot into stock/twrp
Wipe data/cache reset system settings
Flash zip and wipe cache then restart
We are back into the good old Oreo...

hey guys,
i will be flashing Echoe Zen Rom v3 [2.20.40.165] which is the latest rom & will then flash the latest kernel available (Ael Zen v3.5) which was released yesterday... The only doubt i have here is if i flash this rom will be able to flash the latest stock firmware from asus? and if yes how can i flash it... I have seen people having issues with twrp & updating stuff so do i also have to edit the updater script? Please someone enlighten me on this issue of updating to latest stock rom after flashing echoe rom... I know the flashing of entire rom i.e boot.img, system.img etc with adb but is there any other way like ota or flashing directly of stock rom via twrp? i dont wanna edit the updater script & stuff everytime we get an update...
The best way back to complete stock is to use root with CWM recovery and flash the stock zip from your external SD card as the phone goes back to complete stock. Bootloader is locked again after you do this.
hello, currently I am on resurrection remix oreo rom with some old oreo firmware (non-arb firmware by yshalsager).
now i want to flash latest miui pie rom. i wanted to know about some steps to follow and precautions to take...
because I want to come back to rr oreo (obviously with oreo firmware) if there any problem arise or if don't like the miui rom (haven't used on 1 year).
so for this I made the non-arb firmware and firmware-less rom using the tool provided by yshalsager on his website.
because i want the firmware to stay non arb (to be able to come back to oreo firmware from pie firmware).
now i understand that in many cases miui used to wipe complete device when flashing rom or/and it will encrypt device /data
so if people that have tried this will answer my question I will be grateful.
will the miui rom wipe my complete device? (i have already backed up my current rom) (but If it will wipe my storage data, such as music pics etc)
will it encrypt device? such as data partition and etc
if yes, how do I prevent that? by flashing lazyflasher or such?
or is it no problem if it wipes.
if I do need to flash lazyflasher or such, can anyone provide me the zip?
thank you
okay, so I tried orangefox recovery (which automatically remove dm-verity and forceencryption on miui roms).
first I flashed the non-arb pie firmware then I flashed firmware-less rom (created using tool by xiaomifirmwareupdater).
although the device did not get encrypted nor did I lose any data. the ROM didn't boot. it was stuck at boot logo. can someone tell me what's wrong here? and the correct steps?
Hi,
I am running stock Android 9.0 firmware on my Samsung Galaxy S9 (SM-G950F) with TWRP recovery and Magisk.
I want to update my firmware to a newer stock Android 9.0 firmware by flashing it as update.zip in TWRP, without formatting data.
I have downloaded the ODIN flashable firmware from sammobile, but this is not a TWRP flashable zip.
Where do I get an update.zip or how can I genereate it?
Thanks,
Stefan

uhm... wut? You cant do what youre asking. Youll have to get a compiled ROM and flash it. I dont have a rootable version of the S9, so im not familiar with the ROMs that are available, but are there not any 9.0 ROMs you can flash?
Actually, I would also switch to an already compiled ROM, if it wold be possible to do without wiping the data partition. But all ROMs have this as a prerequisite, if you switch to them from a stock ROM.
I will probably try to flash the stock firmware via ODIN with Home_CSC, although this is riskier than flashing the firmware via TWRP.
A better way, as I understand would be to get a Samsung OTA firmware file. Since https://firmware.science is down, does someone know an alternative?

you dont flash firmware in TWRP, just ROMs. And if you flash a deodexed stock ROM that has the same base as yours, you shouldnt need to wipe
Flashing a deodexed stock ROM sounds good. By same base do you mean the baseband version (G950FXXU4CRKB in my case) or the build number (R16NW.G950FXXS4CRLB)?

Hello,
I haven't flashed my phone for about 2 years.
I am running Firehound 8.1.0 64bit with TWRP 3.1.2-0 (I think)
Do I need to flash anything other than the latest TWRP to enable me to flash android 9.0 & 10.0 ROMs? As when I upgraded to 8.0 I seem to remember their being a bit of work involved.
Thanks in advance for any advice you can offer.
All you need is a 64bit unofficial twrp
Format data to remove encryption with twrp & wipe system & cache
As long as your stock base firmware is oero nothing else is required (if you are still on nougat firmware your fingerprint reader will not work unless you flash oero stock firmware or fingerprint fix)
The process is exactly the same for any custom rom

Is there a way to tell whether I am running Nougat or Orio based firmware? The build I am on is from March 2018. I think I remember reading about this back then but I'm unsure as to whether I flashed stock Orio or not.
I will have a look through my ROMs thread to see if stock Orio was a pre requisite.
So if I am on stock Orio, all I should need to do is update TWRP and I'll be good to go?
Edit,
I just looked through the ROM thread and the dev said a camera issue would not be fixed until stock Orio released. I have a new laptop now so looks like ill have to get ADB and fastboot back up and running then fastboot stock Orio before flashing a new ROM.
Thanks for you help

After flashing Oreo I recommended JarlPenguin's TWRP
Hey guys!
I'm rooted with magisk on this ROM - https://forum.xda-developers.com/oneplus-5t/development/rom-unofficial-aosip-aka-derpfest-t3978357/amp/
What would be the best way to downgrade/roll back to an Android 9 ROM? Safely.
Appreciate the help! Thanks.
I just did this process.
You just need to have your twrp updated and flash the stock rom (or other roms).
You'll lose your recovery, it goes to stock, and magisk.
I think flashing a non-stock android 9 ROM is way better, you won't lose your recovery.
If everything goes bad, you can try the unbricking tool for 5t.

So if I'm understanding correctly, it doesn't matter that I'm on the latest firmware as well? All I have to do is find a android 9 ROM (I'm probably going to do oos Aroma) and flash that in the latest recovery installed. Latest recovery being the one I'm currently on twrp 3.3
Yeah, that's it.
I was using aicp android 10 I just flashed lineageOS android 9, all worked well. I'm also using twrp 3.3 that should be OK.
