Does VBMETA have to be applied with each rom? - Xiaomi Redmi Note 7 Questions & Answers

Or is doing this simply a one off if you are coming from a MIUI rom? I am technically adept and have been flashing roms for many years and things are always changing. So I just want to be sure.

Flash it only when you go to custom rom coming from miui stock rom, other than that you don't have to flash it or the vendor when you jump between the other custom roms

So it's kind of like a condom. :good: Thank you!

LOL

Why some custom roms don't need to flash VBMETA ? Even if coming from MIUI ?

you will most likely still need to flash vbmeta after updating your firmware manually.

Ok thx. This coming from MIUI. So I suppose that going back to MIUI' based rom, I need to reflash VBMETA.IMG, right? I take it in the rom ZIP of the MIUI rom, right?

ok to clear this up, vbmeta is only required when going from miui based roms to other custom roms. if u are going to flash a miui based rom, such as .eu, u do not require vbmeta. in fact, since u are going to flash a miui or miui based rom u might as well flash stock miui through fastboot, so there would be no confusion and no additional flashing.
when i was referring to updating firmware manually i meant flashing the firmware packages from xiaomifirmwareupdater.com rather than extracting from the miui recovery rom.

Not every custom rom. Don't need to flash vbmeta e.g. for thelazyindian's LOS, Syberia Project, AEX.

Custom kernel is gone after flashing a rom

Why is it that I have to reflash a custom kernel every time I flash the newest build of a rom?
Any time you flash a custom ROM, it will always include some kernel along with it. Hence, when you flash the newest build of a rom, you're also re-flashing the original kernel that it came with.

I see. Thanks! So I pretty much gotta flash my own custom kernel every time then?
As far as I know yes. There could possible be some way of flashing without the kernel, but I think it's much safer to just flash the whole custom ROM and then re-flashing your own custom kernel.
Yeah the easiest thing to do is just install the ROM with its kernel then just flash your kernel of choice.

Flashing Any Latest Miui ROM Update Through TWRP

I'm on Miui 8.1 Global version rooted, Unlocked Bootloader ,
can I flash Developers rom through TWRP? Without clean flash? Or Does it require clean flash for flashing developers rom on rooted / unlocked bootloader devices,
If I can dirty flash miui global to miui developers through TWRP, will my data gets deleted or wiped ?

It's always better to clean flash dev ROM if you're on stable ROM

No need. Download fastboot rom. Unzip that zip (tgz) file. Go to fastboot mode. Click on flash all except storage. Nothing will get erased. That's better than installing through TWRP

If you're planning to flash incremental OTAs, you should flash the stock recovery. It's easier that way as it takes less data and eases the OTA update process but at the same time you'd end up switching recoveries if you need to flash other custom ROMs

Need Recovery Flashable STOCK ROM

My phone is having issues and i dou t its cuz of the custom rom. I wanna try fixing sumofem by downgrading to stock flashable marshmallow rom or lollipop. So if u guys could help me thats would be great!
I cant flash back to stock by fastboot cuz my bootloader isnt allowing gpt while to be flashed so thats the reason i really need a flashable rom.
Even if i flash back with fastboot. I can only downgradd to 6.0.1 and when i do the camera isnt working alomg with the flashlight.
So fastboot downgrade isnt the option for me. What i need is a stock or only a lilbit modified custom rom based on the stock one.
Thanks in advance

Going back to MIUI

Hi, my device is actually running the latest xiaomi.eu [DEV] ROM, I think it's the 9.4.25. I would like to try AOSP Roms like Aosip, LOS and the others. Can I go back to MIUI after that? I'm asking this because I wouldn't like to lose Stock Camera quality, yeah, I know that GCam exists, but honestly? It's not THAT good, at least with mine settings.
I wouldn't I don't think the unofficial TWRPs are allowing you to go back to official MIUI, but i am not certain of this.
Nobody will answer my questions, and yes i agree gcam does not support our 48mpixel camera so it's useless.
You can revert back to miui,
Download the stock firmware (fastboot) from here, extract it on your computer and then flash it to your phone using "Xiaomi Flash Tool", there is a step by step guide there, just make sure to backup before that.

As far as I know ARB is in the fastboot versions, there is ARB=0 in those ROMs, checked, If you have ARB>0 you'll not be able to flash by MiFlash. However you can flash by TWRP but only upgrade, downgrading in TWRP means you can brick in any time. Of course every single ROM flashing in TWRP require to disable Dm-Verity/ForceEncrypt, to avoid bootloops and problems with encryption after unlocking bootloader.
