Complete setup of Lineage OS

Since in my last post I made a complete mess out of my first time trying to root my K20 and install lineage I wanted to my make a separate post so that I can list all the steps I need to take to correctly setup my phone how I want it.
What I actually want
A rooted device
Lineage OS
Minimal excess files (A clean Install)
Current Steps
Unlock and flash recovery
Backup
Format Data! (It's important if you come from Miui)
Install Q Firmware + vendor
Install LineageOS followed by gapps
Reboot into system and setup device.
Reboot into recovery and flash magisk
Profit???
Feel free to tell me how stupid I am and what I need to add to the list or steps I should take to make this process better.
I also dont know if its possible to get recovery and rom on android 10 versions.
Thanks

Did these steps not work?

Remember:
Chinese firmware: Widevine L3 and NFC support
Indian firmware: Widevine L1 but no NFC support

They may work as it but I was just wondering if anyone could go into more detail or if there was a better approach and from what Kollachi said there clearly is a better way that what I said.

Since I'm in stock ROM and haven't ever flashed AOSP ROM in this phone I'll just back off lol

I like the details steps but I have a few questions.
(Unlock and flash recovery) From what I can tell there are two recovery's Orange fox and TWRP
(Format data) Just format data or are there other sections I should format/wipe
(Install Q Firmware + Vendor) I have no idea what Q firmware is or what vendor you are referring to
(Install Lineage + gapps) Is there a specific version from the Mi 9T pro since the official site doesn't list it

Any of the two recoveries will work. Q firmware means Android Q. Wile data/cache dalvik that's it. Regarding firmware, there's a clear topic of Lineage OS in K20 Pro forum which is still in unofficially state

1. You can take what you want. Orangefox is based on TWRP.
2. Format data is needed if you come from miui. If you did it you are good to go. But it wouldn't be false to wipe system, dalvic, cache
3.https://downloads.akhilnarang.me/MIUI/raphael/ --> Take 10.4.6.0 or 10.4.8.0 (Android 10 = Q)
4. No there is no specific version.

I would recommend the latest TWRP from here
https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568
The dev is an official TWRP dev, so this version, or something very close to this, is likely to become official in the future.
OrangeFox is a heavily modified TWRP and has a lot of added functionality specific to MIUI. If you wanted to stay on stock MIUI, but debloat and have root, etc. then OF would be the better choice, as it has functionality that lets it play nicely with MIUI (it can remain installed when OTA updates are installed)
As someone new to flashing on Android, I would suggest downloading a 10.4.x fastboot ROM from the site I pointed to in your other post, then follow the same procedure to flash the ROM.
Make your choice based on Kollachi's info and what's important to you (HD Netflix - choose Indian, or a working NFC - choose Chinese)
However you MUST change the flash option to 'clean all'.
At this point you've got a nice squeaky clean starting point.
Boot into the ROM at least once, though it's not necessary to go through all the setup.
After that follow Kollachi's steps but you can now ignore the step to flash vendor and firmware as it's all part of the fastboot ROM already flashed.
Wipe cache and dalvik, format data.
There is no official LOS for this phone yet. Hopefully it will go official in the future.
For now just get the current Android 10 based LOS from here.

When ever I think I have the process memories and I follow the steps on my screen I still somehow **** this up and I cant understand how.
My current steps include
Flash the fastboot with the ROM that you linked me in my first post
Flash the recovery with TWRP (Every time I have then tried going back into TWRP is failed to work and prompted the original MIUI recovery)
Install the TWRP zip from custom recovery to try and fix the issue above (Only had this work once on orangefox and then never had success again)
So now I try to just flash the recovery and boot to it using CMD and it works fine
Move the lineageOS files from my PC to the phone SDCard
If I wipe data and the caches as suggested then the lineageOS zip is now go and I am back to flashing the fastboot ROM to restart the process
I know this might seem like im either stupid or just not getting it but could you or anyone else please make a bullet pointed list with links to what I have to download in order to actually achieve this since I cant do anything correctly even when trying to follow the steps.
(Im going to sleep since I have been trying to do this for hours now and I will check reply's in the morning.
Thanks for the help so far EVERYONE

I just told you what I have done and I'm running it so far without issues.
Robbo just said you should flash the whole Chinese or indian rom but I don't like his steps because:
1. File is much bigger
2. MiFlash is just meh
3. If you forgot to change the flash process you are bricked if you don't take the correct firmware for your phone.
Default option in Miflash is set to "Clean all and lock". Every time you use it, you will need to change it into "clean all" or something other.

Yes flashing the whole fastboot ROM does add the risk, if you forget to change the flash option, but you are guaranteed a clean slate and so less likely to have any niggling issues that nobody else has. I would bet large sums of money that many of the issues you see on here, where only one person has some problem and everyone else is fine, would be solved by fastboot flashing MIUI before installing the ROM of choice.
If you know what you're doing and know when you'll be OK with what you've got and know when it's best to start clean, then going with the vendor and firmware is easier.
But if your unsure and new to flashing on Android phones, I will always suggest go with the overkill and know you've got the clean slate to start with.

It's sounds like the main issue is stock recovery is being restored. This is something that MIUI will do when it boots up.
When you first install TWRP you cannot boot into MIUI before booting to TWRP as you instantly lose TWRP. So you need to boot into TWRP first in order to do something to prevent it being overwritten.
Options are
1
Code:
fastboot boot TWRP.img
2 Use the button combo whilst still in fastboot - power and vol+, hold both until the phone vibrates and the initial logo appears.
Now to keep TWRP you need to either flash a custom ROM, flash Magisk or flash the dm-verity script.
In your case you want to flash LOS, so now you've booted into TWRP go ahead and continue with the steps given.
Also, wait until after you've formatted data before copying everything over. You can access the phone as an MTP device when in TWRP, so you'll be able to connect it to a PC and drag everything across, or you can stick everything on a USB OTG pen, if you have one, TWRP can read data from them too.

The exact problem I have is that I cant transfer any files to the device after formatting the data. I follow the steps correctly and I get into TWRP successfully and then everyone has told me to format the data then install lineage but I cant install the OS if formatting the data removes it.
Get device into fastboot
Flash revocery with TWRP
power the device off
hold volume up and power
boot into custom recovery
format data
move lineageOS onto my device
install lineageOS
reboot
done.
This is the list of exact actions I am doing with no results is there something I am missing or something that is in the wrong order.

After format data, reboot your device into recovery again and transfer LOS, gapps and all files you need.
Format data kills the storage.

I always used to reboot from TWRP back in to TWRP after formatting data, but I've recently seen someone saying that they just unmount data then remount it again. I haven't tried it myself but it certainly makes sense and would be quicker too.

Yes I did that and it worked, unmounting and remounting helps detect the storage in PC

Finally Successful
After a long post I have finally finished the process successfully. This was pretty educational for me since I didn't understand any of this at the start I would like to thank everyone who reply's and all the information that you have provided.

need help guys, i stuck in bootloop.
- fastboot rom global china V10.3.17.0 PFKCNXM
- fastboot twrp 3.3.1
- format data
- flash vendor image cn 10.4.6.0
- wipe cache/dalvik
- flash lineage os
- flash gapps nano
- reboot
- stuck bootloop

Boot loop after trying to downgrade EU stable 11.0.2 to EU stable 10.13.17

TL;DR - Tried to downgrade Android 10 Xiaomi EU to Android 9 Xiaomi EU, tried wiping the device (besides storage). I can get into TWRP and Fastboot, just won't boot OS.
Detailed:
I was running the latest Android 10 Xiaomi EU Stable Rom MIUI 11 (11.0.2) and wanted to downgrade because I had a few issues.
I reinstalled the last stable Android 10 Xiaomi EU Stable Rom for MIUI 10 (10.3.17) and it ran fine. I then realized that I wanted to be back on Android 9....
I went and tried to install Android 9 Xiaomi EU Stable Rom for MIUI 10 (10.3.16) and then ran into boot looping.
So then I got into TWRP and erased all data and then tried to copy over the old update file and realized I can't copy over anything even with MTP Enabled.
All the folders in the sdcard are random letters and numbers..
So now I can't send any files over and im stuck wondering how to fix this problem and then go over to Pixel Experience.
Send help! Please!

You messed up with encryptions... Just flash Chinese fastboot rom before pixel experience... and, as always, don't forget: DO NOT lock your bootloader ..

And I would do that by downloading which version of fastboot? Any stable one that I want to run?
Also would it be through fastboot using Mi Flash Tool or something else?
Then the pixel experience would be installed just through TWRP?
Sorry, I just don't wanna mess up.

As you want to flash pixel experience, you need to flash chinese fastboot rom, because pixel experience is based on Chinese firmware. So, by flashing Chinese you will be half way. Pick last stable pie version.. I believe is 10.3.16, don't remember...
Yes. You should use miflash tool, just don't forget: you need to select "clean all" and not "clean all and lock".
Boot into miui system once.
After that just flash twrp through normal fastboot command, as you already did in the past. Then flash PE in twrp...
Remember to boot in twrp just after flash it, if you boot into device it will be replaced by stock one...

After booting into TWRP and before flashing PE, wipe cache and dalvik, then format data. Either reboot into TWRP, or unmount and mount data, then carry on with the PE flashing.

That sounds confusing..
So after flashing the chinese fastboot and starting the phone up once to confirm its working, i boot into twrp and wipe cache+dalvik, then format all data, then restart into twrp and flash pe?
Doing that is just making sure its a clean flash and not a dirty one?

You boot into MIUI once to let it finalise the installation.
Then install TWRP and immediately boot into TWRP.
When changing ROMs you should clean flash, which normally means wiping cache, dalvik and data before installing the new ROM.
In this case it's best to format data instead, otherwise you may get problems with encryption, similar to what your seeing now.
After formatting data, TWRP sometimes has a problem seeing the data partition properly, to fix this you either reboot into TWRP or go to the mount menu and unmount data, then mount it again.
After this you copy the PE ROM onto the phone and flash it.

Custom Rom flashing problem.

Okay. Am currently on MIUI 11.0.3 (the latest one available for RaphaelIN)
So, the problem am facing is that, when i flash a custom rom, my phone gets rebooted to recovery and sometimes to fastboot(this happens occasionally) and i just simply cant get the rom to load.
Sometimes my phone gets into a state which resembles hardbrick (none of the buttons work, even holding the power button for 10secs doesn't) and after sometimes, usually 15 to 20 mins it restarts itself. This has happened thrice till date and all while booting to system.
The Roms i have tried-
-Pixel experience (unofficial) (android Q)
- Lineage OS 17 (unofficial)
- Havoc OS (both official and unofficial) (both pie and Q versions)
-MIUI (European rom)
I have also tried flashing the chinese, indian and global vendor (all done separately) thinking it was a vendor issue, but it also doesn't work.
Recovery is TWRP latest version, have also used orange fox recovery
Bootloader unlocking was done through the official method and the official app.
Any solutions for this problem and has anyone faced these problems or is it only me?

Consider this an overkill solution that always works for me if I run into issues with other methods. It will wipe everything so backup your data and apps.
Download the latest fastboot Indian MIUI ROM (for anyone else reading this download the ROM that is the same region as your phone)
Fully extract the ROM and flash it - make sure, if you use the Mi Flash Tool, that you change the flash option to 'clean all'
Boot into MIUI once, you don't need to actually go through the set-up, just let it fully load.
Boot the phone into fastboot and install TWRP - I recommend the latest mauronofrio TWRP.
After installing TWRP boot immediately into TWRP.
Format the data partition - don't skip this step.
Wipe cache and dakvik - don't wipe anything else.
In TWRP goto the mount menu and unmount the data partition then mount it again - others would suggested rebooting back into TWRP, either way works, you just need to make sure the data partition is properly mounted after formatting it.
Install the ROM of your choice - either have the ROM on a USB OTG stick, or copy it onto the phone from a PC whilst still in TWRP.
If your ROM doesn't include Google apps and services and you want Google, then install GApps - at the time of writing this Android 10 GApps is still in beta and packages bigger than nano may cause issues, so stick with pico or nano, assuming your installing an Android 10 ROM.
Boot into the ROM.
If you want Magisk, once the ROM has loaded, boot back into TWRP and flash the latest Magisk installer - it is possible to flash Magisk without booting into the ROM first and you'll probably be OK, but occasionally it can cause problems, I can't remember the details, but for the sake of 30 seconds I now boot into the ROM before flashing, just to be on the safe side.
At the time of writing this people have recently reported issues flashing GApps immediately after flashing Havoc 3.0 and recommend booting Havoc before flashing GApps. Although others say they've not had any problems. So if you choose to install Havoc you 'might' have problems if you install GApps without booting into Havoc at least once first.
I've never had problems when following this method.

You didn't format data that's why your rom doesn't boot. Follow Robbos nice guide and you are good to go.:good:

I did format the data partition coz that's one thing I and my friends always do when flashing new rom. I don't exactly remember but i think, the pseudo hardbrick thingy started after i formatted the system, data, cache & internal storage.
I will follow Robbos guide adn keep you guys updated on what happened.

Format data = (you will need to type in "yes")
Note: Format data or wipe data isn't the same thing.

Consider this an overkill solution that always works for me if I run into issues with other methods. It will wipe everything so backup your data and apps.
Download the latest fastboot Indian MIUI ROM (for anyone else reading this download the ROM that is the same region as your phone)
Fully extract the ROM and flash it - make sure, if you use the Mi Flash Tool, that you change the flash option to 'clean all'
Boot into MIUI once, you don't need to actually go through the set-up, just let it fully load.
Boot the phone into fastboot and install TWRP - I recommend the latest mauronofrio TWRP.
After installing TWRP boot immediately into TWRP.
Format the data partition - don't skip this step.
Wipe cache and dakvik - don't wipe anything else.
In TWRP goto the mount menu and unmount the data partition then mount it again - others would suggested rebooting back into TWRP, either way works, you just need to make sure the data partition is properly mounted after formatting it.
Install the ROM of your choice - either have the ROM on a USB OTG stick, or copy it onto the phone from a PC whilst still in TWRP.
If your ROM doesn't include Google apps and services and you want Google, then install GApps - at the time of writing this Android 10 GApps is still in beta and packages bigger than nano may cause issues, so stick with pico or nano, assuming your installing an Android 10 ROM.
Boot into the ROM.
If you want Magisk, once the ROM has loaded, boot back into TWRP and flash the latest Magisk installer - it is possible to flash Magisk without booting into the ROM first and you'll probably be OK, but occasionally it can cause problems, I can't remember the details, but for the sake of 30 seconds I now boot into the ROM before flashing, just to be on the safe side.
At the time of writing this people have recently reported issues flashing GApps immediately after flashing Havoc 3.0 and recommend booting Havoc before flashing GApps. Although others say they've not had any problems. So if you choose to install Havoc you 'might' have problems if you install GApps without booting into Havoc at least once first.
I've never had problems when following this method.

Ohhh *****...!!!! It ****ing worked!!!! Though i made some mistakes like clean all and lock in first step, but was able to unlock bootloader almost instantly, no idea why but i can almost instantly unlock certain mi phone's bootloader instantly.

A lot of thnx.... and also happy new year... 1st day of 2020 went quite well for me all thnx to you and i hope yours goes well too.!

Guys i need your help,, i flashed my phones custom Rom tecno 7cs using sp flashing tool.
That worked and it showed the tick icon on my pc.

Flashing problem on Chinese version K20 Pro (raphael)

Hello there,
I'm using the Xiaomi.eu latest Beta rom ATM. I'm trying to flash other roms (like lineage OS 17.1 for example) but it seems to reboot to fastboot everytime. I've tried doing a clean flash, formatting data, dirty flashing. Nothing seems to help it boot into the new rom.
Clearly I'm doing something wrong. If I try flashing the recommended Chinese vendor firmware (stable version), I get an error 7..but my TWRP is up to date as recommended.
If anyone has any idea where I'm going wrong, that would help a lot.
Thanks

Don't know what your doing wrong, but this is my failsafe method should nothing else work.
Flash the latest Chinese 11.0.5 fastboot ROM. Make sure you don't lock the bootloader if using the Mi Flash Tool.
Boot into MIUI once to allow it to finalise the install, you don't need to do the initial phone setup once it boots into MIUI.
Boot into fastboot and install TWRP. I recommend the latest from mauronofrio which should be 3.1.1-32
Boot immediately into TWRP. I use the volume up button while powering up the phone.
Perform a factory reset in TWRP (using the swipe button), then format data (need to type 'yes' to confirm).
Reboot into TWRP using the TWRP boot menu, this ensures the newly formatted data partition is correctly mounted.
Copy over the ROM you want and GApps if needed, then flash.
Boot into your new ROM, everything should be OK. Then boot back into TWRP to install Magisk if you want root.

Yep that seems to have done the trick. At first I was getting frustrated because I thought I was downloading the right Chinese ROM, turns out I was downloading the recovery version instead of the fastboot one.
I think it wasn't working because I was on the beta channel. Switching over to the stable channel meant I had to go through a fastboot flash apparently. I've seen this before on my OP3.
Got lineage OS loaded, thanks for your help!

Can't flash Lineage on MI 9T Pro: "package requires firmware from an Android 10 based MIUI build"

Really badly need some help here. My MI 9T Pro is on MIUI 12.5. When I first tried to flash Lineage 18.1 on the device (a week ago), I got the error message about Android 10 based MIUI build(in the subject line). I flashed the latest stable EEA firmware and tried again (I may have wiped too much in TWRP here: dalvik, cache, data, system, vendor). Then I got into a bad Fastboot loop (couldn't even flash back to TWRP). Don't remember how I got out of that (I think I flashed an empty vbmeta file onto the phone: vbmeta_dv_shivsom.img ).
Flashed back to MIUI stock 12.5 to get a clean start. Worked fine. Then flashed Pixel Experience, which worked fine. Flashed back to MIUI stock. Tried Lineage again. Got the same Android 10 error message before even beginning the flash. Then unzipped the Lineage ROM and edited the file updater-script (removing the Assert lines in the script). Zipped it back and tried to flash the modded ROM. Flash went through, but on reboot it got stuck on Fastboot. Have now done this in several rounds, gone back to stock, tried Lineage 17.1. Tried only doing Factory Reset and Format vs Wiping Cache and Dalvik). I also tried with the latest Havoc 4.8, same result. Tried with a modded Havoc. Tried to flash the latest China firmware before flashing the ROMs, didn't help. I'm totally stuck here and any help would be fantastic.

Forgot to mention. I also get the ERROR 7 message together with the Android 10 error message. (And when I tried to flash Havoc I got the ERROR 1 message together with the Android 10 error message.)

Do you have a global phone or an EEA/EU phone?
If it's a global phone flash the global MIUI ROM not EEA ROM.

Thanks a lot. The phone was bought i Europe (new). Flashed back to the 12.5 EEA stock from mi. But if you think the global version will make a difference, I can try that (if that works, any ideas why the EEA version would cause all these problems?).

You should be using the European ROM with the European phone, global ROM shouldn't make a difference. Try flashing the European firmware that is linked in the LOS OP.
When flashing you do not need to wipe system or vendor.
It is as rare as hens teeth the times when you need to wipe either system or vendor. In future did not do this. In future, only do the standard TWRP factory reset for a clean flash. There is almost never any need top go to the advanced wipe screen in TWRP.

Will do. Yes, I followed bad step by step instructions and wiped too much on the first flash attempt. But any damage from aggressive wiping should be eliminated after I used the official MI flash tool and flashed it back too stock? Or is there any changes that remain on the devise after going back to pristine stock? ( Will stick to Factory Reset and Format Data in TWRP going forward.)

Flashing stock fastboot ROMs will restore everything.
