How to flash GSI in RN8P/HMN8P?

I flashed AOSP_10_Quack_Phh-Treble_v208 many times last night.
but always failed,bootloop.
My step:
unlocked + TWRP
1.factory reset + format /data(or not)
2.flash V208.img to system image
3.format /data or not,reboot
My phone showed Redmi-logo and dm-verity error,
and bootloop.
anybody successed?
Could Somebody teach me how to flash GSI?
Maybe to flash AOSP 9?

It's reassuring to see you have attempted multiple times to flash another ROM and haven't hard bricked your phone.
My guess is you need to flash the dm-verity remove zip file. I'm assuming you have selected AVB 2.0 in TWRP? That's all I can think of but I haven't tried anything as clearly I don't have balls as big as yours

I used these following steps from tvardero :
Flash stock
Flash twrp
Make a backup of system and data (to get back into stock if needed)
Format data -> yes
Flash GSI you want to
To flash another GSI or revert to stock you use your backup of system partition.
NEVER EVER RESTORE ANYTHING ELSE THAN SYSTEM OR DATA, softbrick imminent

I try many GSI-ROM
Most bootloop,even I format /data,disable dm-verity/AVB 2.0 (TWRP by wzsx150)
My steps is
fomat /data,reboot to twrp
wipe /system ,2cache and flash gsi.img(Maybe resize /system to flash gapps)
flash magisk
disable dm-verity/AVB 2.0 with TWRP by wzsx150,or flash disabler.ZIP
GSI ROMs had some different bugs,brightness control,NO mobile signal,
sound,nfc-sim support,googlepay ,bank app etc.,

Really nice to see some testings. I hope we have some some development for our devices

Can't install MIUI custom ROM on Mi A2 Lite

I'm trying to instal MIUI 11 from this link: https://forum.xda-developers.com/mi-a2-lite/development/rom-daisy-miui-11-hybridos-stable-t4003651
However after flashing the ROM the recovery says there's no OS at all. If I reboot it bootloops.
The only way I can go back to recovery is by using adb commands and flashing a IMG. Then TWRP says it can't open destination log file.
What can I do? Thanks!

I'm not sure what you've done with your device and I'm not sure if you know how to read (because there are a LOT of guides throughout the forum), but here we go :
1 - Flash stock ROM (check the forum again on how to do it or Google it.). Do this before you're trying to flash any ROM, really.
2 - Unlock the bootloader and boot TWRP from your PC.
3 - On TWRP go to Wipe and choose Wipe Data, type 'yes' and confirm it to wipe data.
4 - Now you're gonna need to boot into TWRP again, because TWRP sometimes breaks after wiping data, simply go to Reboot section and choose 'Bootloader' in TWRP. This will get you to Fastboot mode, you will need to boot TWRP from your PC again.
5 - Once you get into TWRP, flash the ROM, flash the TWRP.zip if you want.
6 - Go into Reboot section in TWRP and check your boot slot and change it. (If A make it B, if B make it A) and reboot into system.
7 - If you want to install Magisk or any other mod through TWRP, :
7a - if you've installed TWRP.zip previously, reboot into recovery and install your mods/Magisk and then boot into system
7b - if you didn't install TWRP.zip, reboot to Bootloader/Fastboot and boot TWRP, then flash your mods/Magisk. Finaly boot into system.

Step 1 is wrong, miui ports have base stock in built, no need to make a clean flash
Step 5 is wrong, miui ports have twrp in built, you don't need flash twrp zip
Step 6 is wrong, miui ports need to be installed in the current active slot, no needed change slot
If your device have unlock bootloader and enable usb debugging, only boot twrp.img, only boot no flash, like the OP did it (fastboot boot twrpname.img)
Wipe> format data> yes
Install> install miui.zip
Install> install magisk (optional)
Reboot>system

Custom ROMS don't work on my device, how do I restore MIUI?

Hello, unfortunately I've tried flashing Pixel Experience and LineageOS along with the vendor.img from the PE thread but they both don't boot up (infinite loading screen). Also the official TWRP doesn't work for me, but the unofficial one by wzsx150 (LR team) does work.
The problem now is that I cannot restore MIUI back. I've tried restoring all the backups I made prior flashing any vendor or custom ROM (except for the Data partition) but it does not boot, so I have downloaded the EU firmware from the official website and tried to flash it. These are the steps I follow:
-Wipe System, Vendor, Data, Internal Storage, Cache, Cache / Dalvik
-Flash MIUI zip
-Enter fastboot
-Re-apply anti-brick fix
-Flash vbmeta.img (taken from the official MIUI zip) with following command:
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
And this is what I get:
When I first turn on the device, I get the Redmi logo for about 20 seconds, then it reboots automatically. At the startup, TWRP automatically boots instead of System.
How do I fix it?
One last thing: I have the EEU version, idk if that's the root of all the problems I had.

Well, I think I'm in condition n.1 "Can'boot to home screen but you can still enter recovery mode. Then download the firmware update.zip to install it via recovery mode.". As you can see, I've already tried flashing MIUI. It doesn't boot.

Seeing as you have already tried that I would move onto the flashing via fastboot or miflash method.

Hello. I'll close the thread here for now, as an user helped me to install Pixel Experience successfully. Thanks a lot for the help!
(for those who have problems with custom roms, in short: after flashing the zip file, go to the Advanced tab in the unofficial TWRP and choose "Close AVB2.0" and then "RM Encrypt". Apply both of these fixed with ALL the boxes checked for both options. Done!).

Are these steps correct to flash custom rom in 2020?

-use miunlock to unlock bootloader
-put phone on fastboot mode
-type 'fastboot flash antirbpass dummy.img'
-type 'fastboot flash recovery twrp-3.3.1-0-whyred.img'
-type 'fastboot reboot'
-reboot to recovery using phone
-copy gapps & custom rom to phone
-wipe system, data, dalvik, cache
-flash rom
-flash gapps
-reboot
I am currently on MIUI Global 9.5.19.0 with locked bootloader.
Is this method correct? I dont know which guide is outdated right now and which is not. Sorry if this is asked too many times.

Yes this is correct but i want to make some changes in your guide
1. Use orange fox recovery as it is better than twrp and it won't give u any error which u may encounter using twrp.
2. U can use fastboot boot *recovery* to push recovery file and flash its zip after entering recovery (it doesn't need any kind of dummy file flash)
3. Wiping vendor is also there
Thank you

oh ok so basically these are the edited steps to follow now:
-use miunlock to unlock bootloader
-put phone on fastboot mode
-boot twrp using 'fastboot boot XYZ.img'
-flash orange fox zip from twrp
-reboot to orange fox recovery from twrp
-wipe system, data, dalvik, cache, vendor
-flash latest firmware
-flash custom rom
-flash gapps
-flash magisk
-reboot
correct?
thanks a lot btw!

? correct and u can use 9.4.25 firmware as it is best (atleast for me)

Should I follow the same procedure if my phone is on 11.0.3.0?

Now most of the customs support the new pie firmware.
1. Unlock bootloader.
2. Reboot to bootloader
3. Boot to orangefox recovery using
fastboot boot recoveryname.img
4. Copy the orangefoxrecovery.img(extract the orangefox zip) to device storage using the booted orangefox in step 3.
5. Flash orangefox permanently from the copied img file using the booted recovery.
4. If you are planning to use miui don't reboot without flashing magisk. It may reset the recovery to default miui recovery.
6. Enjoy flashing custom roms after wiping(not formating) system, data, cache, vendor etc. No need to format data if you need file ssystem encryption. Formating data from recovery will remove encryption.

Orange fox recovery has aggressive stock recovery deactivation so magisk is not necessary

Question Cannot flash TWRP from Fastboot, TWRP reboot shows Slot A/B, dont know what to do

Ive already flashed a few phones, but this is the first time that Ive got CMD error "FAILED (remote: (recovery_a) No such partition)". So I booted twrp.img, falshed ArrowOS and TWRP from within TWRP and it said something about Slot A and B, which I dont understand ... some guide also said to Format Data, which I did, and then I just could boot into TWRP in Slot A, and no OS on Slot B, which rebooted me into Slot A. I couldnt find any info about this and I dont know what to do. Anybody knows how to properly flash TWRP and custom ROMs please ?

Start fresh by flashing stock MIUI rom through fastboot and proceed from there
1 Boot once into MIUI and reboot into fastboot
2 fastboot boot twrp.img (from platform tools folder)
3 Flash custom rom like ArrowsOS with inject twrp option checked
4 Reboot recovery
5 Format Data by typing "yes"
6 Reboot to system
7 Done

Follow the TWRP install instructions by fastboot boot TWRP.img
advanced, install TWRP
It should then reboot and TWRP will be installed
Then proceed as above by flashing a ROM e.g ArrowOS with TWRP inject.
Then reboot TWRP and wipe data

Use "fastboot boot TWRP.img" to temporarily boot TWRP.
You can install TWRP by using "Install to Ramdisk" inside TWRP and selecting TWRP.img

Did you manage to fix it? I got into the same problem, I could only fix it downloading the most updated version of adb/fastboot. I don't remember where I downloaded it, but it was what solved this problem for me.

well Iam still confused about that Slot A/B thing, but since Ive probably bricked my phone, I flashed the fastboot ROM through MiFlasher and I havent tried flashing TWRP or custom ROM since, there are some things I really like about MIUI so Iam gonna see which ROM Iam gonna choose in the future

Slot A and B refer to Project Treble, where there are 2 separate partitions. 1 for OEM like Samsung and other for core Android OS. That way Google can update the OS partition with security updates without having to wait for Samsung to implement those security update into their version of Android, as was the case before Galaxy S9. Needless to say, this way security updates get pushed out way faster, because there is no need to wait an entire year (I'm looking at you Samsung) for OEM to finally implement it. Hope this clears things up for you.

there is a slight problem with this ... I cannot upload any file to the phone, because I have wiped Data, so there is no folder that I can access from the PC, so I can only sideload .zip files, and most of the .zip files just doesnt work for some reason, only ArrowOS, but not the PixelExtended, nor CrDroid ... I cannot even sideload TWRP.img to install it into ramdisk
EDIT: after sideloading ArrowOS and booting TWRP using "fastboot boot twrp.img", I can access internal storage, so I uploaded twrp.img into /sdcard/Download folder, installed it into ramdisk, rebooted to Recovery and now successfully flashing CrDroid ROM that I uploaded to /sdcard/Download

You can adb transfer files in TWRP. You could also use a USB stick connected via OTG cable

how exactly should I proceed ? flash fastboot stock ROM with MiFlasher, boot into bootloader, boot twrp.img, wipe data, and then what ? which slot do I choose ? should I install TWRP into ramdisk, reboot into recovery and then flash custom ROM ?

sooo what seemes to work for me now is, that I formated data, then flashed PE ROM from OTG and booted into it without any problems
