[ROM][10.0][UNOFFICIAL] LineageOS-17.1 [begonia/begoniain]

[dedalumine]

I used vbmeta.img from
fw_begonia_miui_BEGONIAEEAGlobal_V11.0.3.0.PGGEUXM_d7349241eb_9.0
Why did you choose V10.4.5? I was on MIUI global 11.0.5.0 (PGGEUXM), too, unfortunatly this version does not exist online in the repositories.

OMG!!
You just save my ***! nxt518 (a second time!!)

I look for V11.0.5.0 PGGEUXM for one our. I think at the end i mess up with the version numbers . Strange that this version is not available...
I didn't proceed yet: i was looking for potential comments here... Well... thanks to the replies and for your close reading !!!
I just download the indicated firmware and took the vbmeta.img from fw_begonia_miui_BEGONIAEEAGlobal_V11.0.3.0.PGGEUXM_d7349241eb_9.0. as i understood it worked for you.
Thanks again!
I flash lineage on ginkgo two days ago, and i didn't do anything with vbmeta.img (i just flashed the lineage recovery directly). It seems that i was lucky...

I think i will proceed on begonia another day, just to be completely sure . I still would like to have a better understanding on the Android Verification Boot (e.g. is it disable for all life of the device, does ROMs re -enable it , as vbmeta.img is part of the lenieage zip file...)

@theimpulson
Thanks for your work on this device to have LOS , and for kind reply to provide indication for unexperiemented user... I would still be more comfortatble to first flash wit ik and preloader (prior to the desactivation of AVB). At least for my understanding it shouldn't arm.
Thanks!

I believe it achieves the same result in the end. LR.TWRP is a closed source, hence I can't tell what method it uses.

I hope I can ask once more, though it will probably be a dumb question. Since you mentioned LR.TWRP is close sourced, isn't there a security risk while using it (f.e. code injection while flashing)? Many thanks.

The sole reason you need to flash vbmeta image on this device prior to doing modifications is that Xiaomi has enabled verification/AVB on the recovery partition as well. On QCOM devices I work with, this is limited to system and vendor partition, but on this device, it basically covers every single partition possible which user might tamper with.

It shouldn't harm to flash preloader stuff first but I don't know. I was on MIUI 12, did what I told you before and my device is fine.

I don't think so, I decompiled and checked it, seemed normal to me. in any case, if you are unsure, you can always reflash from LineageOS recovery after the initial install.

Im on MIUI Global 12.0.2 and Android 10 QP1A. I have unlocked this one using Xiaomi unlock tool. For getting this rom installed do i need to.

Flash twrp
Downgrade to A9
Flash this rom

Are these the correct steps for me?
After installing lineageos how do i get root permissions?

There are step-by-step instructions by the author himself:

If you are coming from Stock ROM (MIUI), here is how you do it:

- Unlock your bootloader
- Disable AVB by flashing stock vbmeta.img with the following command fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
- Find a decent working TWRP, flash, and boot it using the manual key combo (official TWRP on Android 9, LR.TWRP on Android 10)
- If you have begoniain run this command adb shell resetprop ro.product.device begoniain
- Format data
- Flash latest LineageOS build
- Flash GAPPS if you want otherwise skip this step
- Reboot back to fastboot and flash LineageOS recovery
- Reboot to system

Done

If you are coming from another custom ROM, here is how you do it:

- Flash LineageOS recovery, and boot it using the manual key combo
- Format data
- Flash latest LineageOS build
- Flash GAPPS if you want otherwise skip this step
- Reboot to system

Done

You can get root privileges by flashing Magisk from recovery.

Okay so the miui 12 and Android 10 do no longer require downgrading to A9?

Yes, downgrading is no longer necessary.

Bug report: using Signal Private Messenger
When I initiate a call using Bluetooth, it takes a few seconds before the other party can hear me.

It is LOS issue, as I was using the same with POSP and didn't have the issue. It was also there in older versions of LOS I had tried in the past

Let me know how I can help debug the issue

Beeing on latest LOS i tried to upgrade Firmware to fw_begonia_miui_BEGONIAEEAGlobal_V12.0.3.0.QGGEUXM_b8772f9b12_10.0.zip

But endend up in Bootloop...could you please tell me which of the latest Firmware is safe to upgrade?

Afaik you don't use official firmware, but a custom one baked into the ROM.

Logcat and dmesg while reproducing the issue will be appreciated

You are not supposed to do that. I ship the required firmware in the builds themselves.

I will try. I cannot reproduce it at all times.

Where can i find this lr. TWRP

Where can i find this lr. TWRP

It's on the forums here. Make sure you download the correct one.

Hey. Someone can tell me if SIM 1 or Sim 2 can be disabled without extracting them?

Thanks

Flash magisk from lineage recovery? or TWRP? I've tried several methods to install magisk and at times it says installed, but safety check always fails. Anyone has been able to fix that?

What safety check do you mean?

 

[wojownikhaha]

What safety check do you mean?

SafetyNet. Pass result is required for example by McDonald's app.
