New to device and the whole firmware thing - OnePlus 3T Questions & Answers

OK, long story short. Came for the nexus 6 and nexus 6p to oneplus 3t. The 6p had to flash vendor.IMG after every new ROM flash. But what is this whole firmware thing in this device? I have tried to find answers before asking but, what should I DO and NOT DO to have a brick? Like, wanting to go from a nougat ROM to an Oreo ROM, but not sure how. And then if I wanted to go from a n/o ROM to a beta, not sure how...then if I wanted to downgrade from an o or beta ROM.......please help

Treat the OP3T pretty much the same as you would the Nexus 6. The only difference is, like you've discovered, that OnePlus provides firmware files rather than factory images.
The installation instructions for the different firmwares (stable and beta) are found in the first few posts of the respective threads:
https://forum.xda-developers.com/oneplus-3t/how-to/rom-oxygenos-3-5-4-mm-ota-update-t3519074
https://forum.xda-developers.com/oneplus-3t/how-to/coming-update-oos-based-7-1-t3564240

It's pretty much the same as flashing vendor image. OnePlus just simply offers Firmware images which flash the Modem and the Firmware.
If you're gonna be on OxygenOS and Custom OxygenOS ROMs then you wont need to worry about flashing the firmware. Some of the Custom ROMs such as Paranoid Android and PureFusionOS also flash the recommended firmware automatically.
However, others don't and require you to flash a particular fimware image manually. Usually the Firmware to be used would be mentioned on the ROM thread itself.
Once you've Unlocked the bootloader and flashed a custom recovery, The most common process for flashing ROMs which do not have an included firmwares goes as follows:
1. Reboot To Recovery
2. Wipe Cache & Dalvik Cache, System and Data Partitions
3. Flash Firmware
4. Flash ROM Zip
5. Flash GAPPS
6. Flash Magisk/SuperSU (Optional).
7. Reboot
And that's it.
That is the standard procedure for most of the ROMs, but, I'd advice reading the OP Instructions properly first in case theres anything different.
PS. For moving to Oreo from Nougat, follow the same, but be warned, If your current ROM is encrypted and the new one isn't you'll be locked out of your device until you flash the old ROM back OR wipe userdata with fastboot, which wipes the Internal Storage.
PPS. For moving from a Custom ROM to Oxygen OS, best way to go would be to flash the official recovery again and sideload the official ROM zip via ADB (In some cases, encryption still might cause the same issue as above)

That was very informative, thank you!!! Just one more question tho. What would happen if I didn't flash the correct firmware? Like, there is a RR ROM with custom sultan or something that looks like it needs a beta firmware, I'm not in beta firmware, so would I have any issues?

I'm not entirely sure but in most cases the ROM would simply refuse to flash. Like for RR, if you don't flash a correct firmware then the flashing returns an "Error 7" and the installation stops. But even if it does flash through, it would either not connect to a network or get stuck in a bootloop, but nothing too serious which you can't rectify.

omnirom 8.1 how to install

It's been a year and a half since last time i had messed around with custom roms.
I am currently on stock 8.0 Oxygen OS. What would be the steps to install OmniROM 8.1?
I'm thinking the following.
1. unlock bootloader
2. Flash TWRP
3. Root
4. Wipe/format
5. flash OMNI rom 8.1?
Do I first need to update to 8.1 somehow?
You may want to update to the latest Open Beta firmware, which you can get the standalone files from here ( https://forum.xda-developers.com/oneplus-3t/how-to/firmware-beta-10-t3631166)
Flash this before flashing the ROM.
Also you may want to flash the Root method after flashing the ROM. Your best choice is Magisk, since it's getting ready updates and it has many extra features. SuperSU is old and not done by chainfire anymore, so don't flash SSU.
Also remember to wipe these specific partitions:
System
Data
Cache
Dalvik Cache.
I'm not sure by what you mean by "Updating to 8.1" as OOS is still on 8.0, even the Open Beta's. Flash the latest Firmware from Recovery and you should be good go.
Also, don't forget to grab NezorFlame's unofficial GAPPS, since OpenGAPPS still hasn't been updated to 8.1.
(https://sourceforge.net/projects/unofficial-opengapps-8-1/files/arm64/)
Also just keep in mind, unlocking your bootloader will wipe your internal storage. This is a security feature and cannot be bypassed.
IMO, there are better ROMs than Omni. You should try Z-Unleashed or Resurrection Remix 6.0.0. They're the best ROMs with the best customization and usage per user for now.
Good luck, and happy flashing!
You don't need to wipe data if you're going to unlock bootloader, since as mentioned earlier, unlocking BL deletes all of yor data.
Dalvik Cache isn't used anymore (we are on ART now), so no need to wipe it separately, it even reside in /data partition.
Also no need to flash firmware files if you're on OOS 5.
ROM, GApps and Magisk will be enough.

Well, most of the ROMs recommend Open Beta 22 firmware, since this is the FW the developers build the recently updated ROMs on. He may experience issues if he's on OOS 5.0 fw.

Please help to install ROM in [Raphaelin]

Please help me. I can't seem to understand what exactly I need to do in order to install a custom ROM on my K20 Pro (Global 10.3.5.0.) I have tried following this (https://forum.xda-developers.com/k20...0-pro-t3953844) post thoroughly and others as well, but can't seem to exactly understand what I am required to do. Most custom ROM's state [Raphael], but as I purchased this device in India, it would most probably be [Raphaelin], after unlocking the Bootloader and installing TWRP, am I supposed to flash a Custom ROM (for ex. Lineage OS) directly or would I have to install a ROM which would make my device [Raphael]? Vendor and Firmware have gone over my head, I do not understand what I need to di. If someone could help me out, It would be mean a lot. Thank you.

If you're running stock MIUI and haven't moved to any custom MIUI's till date then you can straight away flash LOS. Moreover, most of the custom roms work on multiple vendors irrespective of whether it is a China Vendor or India or Global. It doesn't matter till the time the developer specifically asks you to be on a particular vendor.
Vendor isn't a dreaded thing. It's just the drivers needed to run the various components in the device (BT, WiFi etc). Till the time you don't wipe the vendor partion in twrp, you would always be good to go. You could carry on flashing custom roms w/o careing about the vendor.

Thank you very much for your reply. So, just to check if I have understood correctly. I can just install TWRP and then flash Lineage OS straight away, right? I checked (https://forum.xda-developers.com/k20-pro/development/rom-lineageos-16-0-t3965311), and it mentioned:
Instructions :
Download the latest build and GApps
Reboot to recovery
Flash proper vendor and firmware
Flash the latest build and GApps
Reboot
What is "proper vendor and firmware"? And would I also be required to flash this?
Thank you.

Go back to the Lineage instructions and read immediately below that. It starts P.S.
It explains exactly proper vendor and firmware means.
No you won't need to install anything for this step

Nope ! You don't need to flash vendor + firmware as you already running an untouched stock MIUI build. That is for people who are coming from either modified MIUI builds (EU, Miroom etc) or custom roms with a different vendor (India device running on China Vendor)
Custom roms don't carry the Vendor Firmware files and you can only modify the existing Vendor when you move to other region stock or custom MIUI roms.
Back up your data on Internal storage to a safe place either on a PC or OTG. Skip this step if you have nothing important.
Boot In TWRP
Wipe System, Data , Cache , Dalvik
(Don't reboot at this point, Not Even a Recovery reboot)
Flash LOS
Flash GApps
Go to Advanced Wipe and Format Data by typing Yes
Reboot

Did you do FORMAT Data (not just Wipe) when you installed your custom ROM, and before rebooting?

How to flash an AOSP ROM?

Hi there,
I am currently on MIUI 11.0.6 Global version and I am looking to unlock my bootloader and flash an AOSP rom (Android 10). I have read the threads that give detailed steps for flashing ROMs but the information was very scattered across many pages and threads and and got me somewhat confused. So can we get simple steps on how to flash a rom coming from locked bootloader and MIUI? Are these the correct steps?
1. Unlock bootloader with miflash
2. Flash TWRP with ADB or Xiaomi tool?
3. Wipe data partition in TWRP (Factory reset under wipe section??)
4. Flash vendor and then firmware
5. Flash ROM and Gapps
6. Is it necessary to flash DM Verity if you flash latest magisk??
7. Boot
Any feedback on what's the best ROM in your opinion is much appreciated!
3. Format data by "yes" is obligatory when you flash over miui.
4. No needed
6. No needed. I never flash it. I prefer my data encrypted. But notice, when your data encrypted you must do format by "yes" everytime you flash another rom.

Every rom is excellent. If you like MIUI than try xiaomi.eu, RevOS or if you like AOSP than try PixelRom, Pixel Experience, HavocOS etc. The library is still expanding and you have so many choices

Bring light into the darkness of encryption

Hi togehter,
I had some problems with flashing new custom roms and ended up in a bootloop with not being able to boot to recovery. This could be solved by flashing the stock image with the xiaomi flash tool.
Before I will fu up again I would like to bring some light into the darkness.
When coming from Stock Rom:
1. Unlock Bootloader -> done successfully
2. Flashed TWRP Recovery -> done successfully but storage (data) was encrypted
3. Flashed Magisk via Recovery -> done successfully (storage still encrypted)
from here I was happy using the Stock Rom with Root.
Now I started messing things up:
Because there are a few things that bother me about the stock rom i wanted to use lineageOS/Pixel Experience. So I proceeded as following:
1. Backup my data (still have to enter key when starting twrp to decrypt the storage) -> done successfully
2. Flash LineageOS -> resulted in bootloop to TWRP
When entering twrp there was no query about the key and data where encrypted. Also the Backup was not accessible .
3. I used all in one tool to erase storage and decrypt data. -> successfully... Now i was able to place data on the internal storage again and start flashing a rom
4. Flashing LineageOS -> done successfully and able to boot into rom
Back to TWRP data was encrypted and I had to enter key.
5. Flashing remove force encryption script via twrp. -> done but now i was facing boot to black screen. TWRP was not working anymore.
Only way to get it work again, was flashing stock image.
Why is the data system always encrypted. This is rly annoying and backups don't work, because i can not encrypt them. Also, I can not put any files on the memory because it is encrypted.
I would rly like to try a custom rom, but I would also like to be able to go back to a backup. What have i done wrong?
You have to flash no dm verify right after formatting data & flashing rom. Don't let it boot.
I would recommend using the stock firmware. Los/AOSP is rubbish for our device, it's too unstable, lacking features and has worse gestures.

You need to format data (not just wipe data) in TWRP. Some people suggest before flashing a ROM and some say after, but I don't think it makes a great deal of difference either way.
Make sure you either flash the appropriate firmware and vendor recommended, or the fastboot ROM of that version.
Then in TWRP wipe cache and dalvik, then format data.
Reboot into TWRP, or unmount and mount the data partition in TWRP so it correctly reads the data partition.
Copy across the ROM (and GApps if needed)
Them flash.
Boot into the ROM and you should be good.
After initial setup, if you want root, boot into TWRP and flash Magisk.
From here, if you've set a pin on the ROM, you'll be encrypted, but everything should still work normally. You should be able to access everything normally in TWRP and also perform backups. You should be able to got data across from/to a PC normally.

Not true in many ways.
There is need to flash no dm verity. It's one way of solving the issue, but it's not the only way. You should only do this if you know what it's for and if you know you want this.
AOSP ROMs are not unstable. I've been using them on mine for over 4 months. None are perfect and they have a few minor issues/bugs, but they are far from being considered unstable. I've never had shutdowns, reboots or FC'S.
Thanks for the replies.

So for example with LineageOS 17 I can use the global vendor and firmware, but sometimes in the thread it is recommended to use chinese vendor and firmware. In this case I should flash another vendor and firmware then the global one.
What do you mean with a fastboot rom. How can I identify one of them?
Is the MiuiMix Rom a fastboot rom. This one changed my vendor and firmware. After flashing this rom, my bootlogo changed to redmi... Am i right with this suggestion?

Fastboot ROMs are official ROMs that are flashed through the Mi Flash Tool
, with the phone booted into fastboot mode and connected to the PC. They contains almost all partitions, including vendor and all firmware. They will be a .tgz file. They are mainly used as an almost failsafe way to recover the phone, should you mess things up. Flashing them will restore the phone to factory, so will lose TWRP, but you're guaranteed a clean starting point.
If, for example, you want to install Havoc 3, it is recommended to flash it on top of either China or India 10.4 vendor and firmware. So if you're phone is currently on global firmware, you would then need to flash, say, Chinese firmware and vendor flies, before flashing Havoc.
If you have been previously flashing other mods, such as 75Hz, screen refresh rate, for example, then you might choose to flash the official Chinese fastboot ROM, instead of just the firmware and vendor, to ensure that you've cleaned the phone of any mods, etc. In most cases you will be fine flashing firmware and vendor, though.
Miuimix is a custom ROM, which is based on the official China MIUI ROM. Because it's based on the China ROM this is why the logo changed to Redmi.

So in this case, i can just flash this rom and there is no need of flashing a diffrent vendor or firmware.
So final question: I'm happy with the stock rom plus root. I would like to try a custom rom but I'm not willing to go through the whole installtion procedure again. Is there a way of making a backup and keeping it?
When I backup the stock rom right now, the backup will ne encrypted again...When I formate the data, all my data will be gone again ?

Updating a rooted Redmi 8 with custom recovery

Hey guys I was wondering something I haven't installed the latest update yet and my phone is rooted and has TWRP on it soo not sure if i can just update with all that or like i should restore the phone to its original state then update
Last version of TWRP I tried (3.4.0-0) did not work properly with Android 10, don't know about the new 3.4.0-1 because I switched to OrangeFox which can decrypt Android 10 without issues.
As for the update process, you need to get the Recovery ROM update package, you can download it from the official xiaomi site, put it, Magisk and your kernel if you use a custom one either on the phone's internal storage or even better your SD card and flash from recovery in this order:
1. ROM
2. Kernel
3. Magisk
4. Wipe Dalvik\cache
5. Reboot to system
I did it exactly like this a few times now, granted it was with xiaomi.eu instead of stock but the process should be the same.
This should just update the phone without wiping anything and with maintaining root, just make sure to do it from a recovery that can decrypt the phone.

Well I have a few questions
By recovery ROM you mean from here https://c.mi.com//miuidownload/detail?device=1900376 the full ROM? like I just flash the ROM file using TWRP well OrangeFox version right and it will keep all my apps and data
Yes, you flash the rom from mi.com.
Don't "just" flash it or you'll loose root and OrangeFox, flash in this order:
1. ROM
2. Kernel
3. OrangeFox (I added this step because you are on official MIUI and the update will replace your custom recovery unless you re-flash it after the rom.)
4. Magisk
5. Wipe Dalvik\cache
6. Reboot to system
Before flashing make sure you are flashing the right rom for your variant and region.
Other than that, you should be good, I updated like this three times and had no data loss.
