Installing ROM without included kernel & recovery

Hello forum,
i'm currently trying to find the best software solution for my Xperia Z1 Compact and i already got close to what's possible.
I found this ROM which is working almost perfectly except that it overrides the recovery with a dual recovery with an older TWRP version which prevents me from doing critical flashes and backups.
I only need TWRP 3.0.2 on /recovery, nothing else like PhilZ or anything else.
When i flash TWRP 3 for Z1C and reboot to recovery or press Vol-Up when booting i get a blackscreen boot loop which can only be fixed by flashing an old TWRP or wiping the entire phone from fastboot.
Another problem is that updater-script formats /system and /data to ext4 and mounts them like that which is a problem because i'd like to have F2FS on all of my partitions.
I already tried removing /kernel/ and /dualrecovery/ from the .zip and modifying updater-script to not format both patititons and mount them as F2FS, but when trying to flash this modded .zip it fails to flash (probably because an integrity check?).
So what i need to do is:
Remove recovery from .zip
Remove kernel from .zip
Modify updater-script to not format any partitions and mount them as F2FS
Any help, resources and tipps are appreciated. I'm running Windows 10 x64 but i don't think i'm able to build a ROM on my own as i have only little programming experience.

I don't know much, but I am surprised that flashing twrp 3 causes that problem. What method are you using? Try using Rashr to flash twrp 3 img, then try to boot to recovery. If vol up doesn't work, try vol down, (that's what works for me). Somehow I don't think you'll be able to just remove those things from the ROM and have it flash fine. Your better chance is to get twrp flashed, then figure out the F2FS, etc. Also, there are custom kernels for stock-based roms, and don't forget that twrp 3 is not official on Z1compact, so read threads thoroughly to make sure what you're trying to do is supported. I know many of us have twrp 3 on our phones, so I would look more into that.

Hi,
I had the same issues and maybe this helps.
- install your rom and go into dual recovery and choose twrp
- in twrp go to install and choose "IMG" and not "ZIP"
- you can now install the new twrp version via install !

Maybe you should not flash that ROM because it seems to contain malware. Have a look into the thread.

Change file system

Is it possible for the whyred change from ext4 to f2fs?
I try with the ultimete official TWRP (I can't insert the link but i talk about twrp-3.2.3-2).
I start in recovery mode, go to wipe, advence wipe go on cache and data and change file system, but the recovery don't mounts partition, so i can't flash any ROM.
Someone can help me?
Thank you

the recovery (twrp / orangefox / redwolf) can change Fs only to given formates! and i don't think so f2fs is one of them!
but
it seems like you are having encryption error!
boot in to recovery via fastboot! fastboot boot recovery.img and press enter! once you are in recovery! , format DATA type YES and go ahead , and then change ext4 to exFat and then back to ext4. then Wipe /data /system /cache /vendor partitions... ,, now flash LinageOS (even if you are not going to use it) after Linage OS is flashed, simply boot and use for few mins! ,,, not go back to recovery! wipe partition and FLASH ROM as per your wishes, flash GAPPS and Magisk (if you want root)

Impossible with the official twrp, fstab doesn't support f2fs as you can see here.

Thanks!

I've opened an isue in the developer's git, we'll see if we're lucky.
Edit: @Xatu2 https://github.com/Ankit-Gourav/android_device_xiaomi_whyred/issues/1

So, in base to answers on GitHub ,for use th file system F2FS i need to use twrp 3.2.3-0 and next tray to install a ROM with a kernel that support F2FS, yes?

there is still no rom support f2fs so you cant change to f2fs, it get error 7 when you try to flash these roms

I correct it for a moment, I recently tried to flesh the last stable twrp(3.2.3-0) and all the backup features go perfectly.
I subsequently tried to format all the sectors with file system f2fs and I tried to install the last extended AOSP obtaining the error you said only on the system partition(error 7, but i have an idea for solv it..i think).
I restored the system partition to the ext4 format, I tried to run the flash again, not getting errors and getting the ROM working BUT it's block on boot animation...i don't know why...
Perfect no (?)

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 mount vendor or system after clean flash of full ota zip from google

Hi! for the past few days I've been unable to mount vendor or system in any custom recovery I try. I clean flash my phone to the latest build and then boot to a custom recovery in fast boot (twrp and shrp) and neither will allow me to mount vendor or system. I don't know what I'm doing wrong. Thanks!

Question Cannot decrypt Data

I'm using CRDroid 8 and the latest twrp-3.7.0_12-0-alioth.img from the official TWRP website. But when I go into the recovery it doesn't prompt me to put in my password/pattern and therefore i can't decrypt/mount the DATA partition.
Is there any way to fix this without formating data/deleting all of my files? Maybe another version of TWRP?
I'm trying to use adb pull to get all my files from my phone because I can't boot into system.

Try orangefox recovery

you can use 'unofficial twrp 3.7.0_12 skkk' if youre used to twrp and dont want to switcg but orangefox is better

Have a look here.
