Yes, I even flashed the recovery image from within TWRP and rebooted to recovery again. Still didn't work.

Note this was on the new 10.3.6 stable MIUI release that got rolled out recently. Not sure if it has new detection or anything that rolls it back.

Anyway I have resolved my issue now all is good.
[Xiaomi Poco F1 Questions & Answers] iitchan25:
How did you fix it?
[Android General] TheZakDroid:
Hello,

On many custom ROMs I've seen that the default icon shape was different. For example on AICP Oreo ROMs they use Squircle icons and on GZOSP ROMs they use square icons.

I know that to make circular icons you need to extract the /system/framework/framework-res.apk, but how do you change it to be any shape?

HOW TO (temporarily) DOWNGRADE BACK TO OREO FOR BOOTLOADER UNLOCK

(or DOWNGRADE BECAUSE YOU DON'T LIKE PIE)

1) DOWNLOAD FIRMWARE AND DEV PATCHED LGUP

* Download

Oreo KDZ you wish to install -- for bootloader unlock would be H930 20d or h930 20r.

(If you just don't like Pie, then choose the most recent KDZ in that thread, which is 22j at the top)

* DOWNLOAD THIS DUAL VERSION OF DEV PATCHED LGUP, made by [MENTION=2651082]tecknight[/MENTION]:

https://androidfilehost.com/?fid=11410963190603845019

(Or use attached file from bottom of this post. Thanks to [MENTION=2651082]tecknight[/MENTION]! Please

go here and click the THANK BUTTON

!)

_________________

2) INSTALL DEV PATCHED LGUP

0. Uninstall any prior version! It will just confuse you or may conflict with this newer version.

1. Extract LGUP_DualMode.zip to a folder on your PC.

2. Browse into the folder and launch LGUP_Store_Frame_Ver_1_14_3.msi.

Follow the prompts to complete the install.

3. In that folder, right click and select "Run as Administrator" on "SetDev.bat" to set LGUP to developer mode

4. Launch LGUP using the desktop shortcut.

Choose Process : PARTITION DL or REFURBISH

----------------------------

3) DOWNGRADING ANY LG V30/V30+/V30S TO EARLIER OREO KDZ FIRMWARE

1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)

2) open patched LGUP and flash OREO KDZ to DL PARTITION mode. In the pop up box "Select All". Use the attached patched LGUP in this post.

You can also use REFURBISH mode, if you wish.

3) Master Reset (

post 101 of Frankenstein thread

)

5) DONE.

It's fairly easy. Most people breeze right through this. But if you have any problems, go through this list:

Make sure you in download mode BEFORE opening the patched LGUP file.

This is at the top of the list as some people forget to do that. The remainder are in no particular order. If that doesn't work,

Try different USB port,

Try different USB cable,

Try different computer.

Reinstall

LG mobile drivers on your PC.

Reinstall dev patched LGUP again, making sure the files are placed where they need to go (LG Electronics folder, etc).

Reboot the computer.

If you ask for help, that's the list of items we are going to give you anyway. ;)

WARNING: In LGUP do NOT go messing with modes not mentioned in these instructions. Especially do NOT use Chip Erase.

ROOT Your LG V30!

Sticky everyone should read. ;)

____________

EXTRAS

If you root with stock Pie KDZ (after unlocking bootloader in early Oreo), then you will need to flash Magisk modules or manually edit build prop to get root-enabled DTS, Equalizer, and lockscreen weather animations. Dual Speaker mode gives you audio directed at your face, besides the main downward facing speaker. High Impedance Mode give you more volume.

(NOTE: The TWRP flashable zips already have this, thanks to the devs who make them.)

* Fully enable LG DTS 3D stereo (root needed) + Equalizer

* LG V30 Lockscreen EXTRA Weather Animations Enabler

* DUAL SPEAKER MODE + HIM (High Impedance Mode)

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
Yeah no need to flash anything extra.

The ideal thing to do would be to keep the bootloader unlocked. Flash pie kdz, install twrp and then flash the ZIP by seadersn
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] dimitrissot:
Thanks. My bootloader is already unlocked. So I factory wipe then flash the stock pie zip and then magisk right? Why I need the kdz if I already have twrp and my bootloader is unlocked?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
Have you already flashed pie KDZ once? If yes then there is no need to flash it again

Yes zip an then magisk
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] dimitrissot:
No haven't flashed pie kdz before. I am on Havoc ROM. I rooted the phone when I got it with stock Oreo and from then I use custom AOSP Pie ROMS like Havoc. Now I want to go to stock Pie.

---------- Post added at 10:08 PM ---------- Previous post was at 10:05 PM ----------

If I only flash the pie Zip without the kdz step after a factory wipe I will loose root?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] FaceTheSlayer:
Yes, you should dl latest magisk and flash it right after rom flash
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] dimitrissot:
So I can flash just the zip? No need for the kdz step if I'm getting you correctly? It won't lock my bootloader again?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] FaceTheSlayer:
Bootloader wont be locked again, and you can flash zip and it *should* work. I just flashed zip wihtout kdz flashing and everything is ok, but I'm coming from latest stock oreo.

Edit: i did a full wipe and also wiped internal storage.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
No, flashing a TWRP flashable zip (ROM) won't lock your bootloader. This is just stock-based ROM. You'll need to reflash Magisk again, just like any other ROM.

HOWEVER, with these stock firmware TWRP-FLASHABLE zips, you may need to use older Magisk 18.x until it's successfully completed. Then you can update to 19.x. I've asked [MENTION=3138121]seadersn[/MENTION] what he used, but have not seen answer yet.

If for some reason it doesn't flash well, then Plan B is to use LGUP to flash the full KDZ (No, it won't lock your bootloader), then reinstall TWRP and the three root files. See WTF SECTION 6.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] dimitrissot:
Thanks! I guess that if this ROM is a full one as it seems to be (not just an upgrade) there won't be any issues I hope. Recovery won't be affected as I can understand so I can use a backup if something doesn't work..
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
The stock firmware Oreo TWRP flashable zips don't like the latest Magisk. May be the same for Pie. If so, then you have to flash Magisk 18.x first, reboot then update to 19.x.

EDIT:. [MENTION=3138121]seadersn[/MENTION] said he used Magisk19.3. OK, then!

So I installed the update via dev patched LGUP with Partition DL. It went smoothly, including flashing TWRP. I ran into the encryption problem, but used the links on this thread to get past it. However, when I tried to install Youtube Vanced and All Lock Screen Weather Animations with Magisk 18.0, I was greeted with a black screen upon reboot.

So i am posting the process i followed:

I Didn't install any extra encryption disabler or root checker zip during flashing because its already included in the ROM

Step 1: Backed up everything.

Step 2: Wipe data, system, cache and dalvik

Step 3: Install Pie Zip 30b

Step 4: Wipe dalvik cache

Step 5: Install Magisk 19.3

Step 6: Wipe dalvik cache

Step 7: Dont reboot system because you will get an encryption error. Instead go again to advanced wipe in TWRP and format data to remove encryption.

Step 8: Reboot System

Also i tried to reinstall magisk through recovery but i get an error saying Failed to decrypt data - unable to mount storage. Any suggestions?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
You restored Oreo from TWRP and when it rebooted TWRP was no longer installed? That makes no sense.

If phone is encrypted -- and this is all over the instructions in post #1 as well as mentioned in the threads -- you need to flash the new encryption disabler. It's attached to post #1.

Try Master Reset.

If that doesn't work try going into Download mode manually and flash KDZ via LGUP. Your bootloader will still be unlocked but you will need to follow the Section 6 WTF Instructions to reinstall TWRP and and root. This includes specfic steps involving the new encryption disabler and what order to flash Magisk. I've updated that section to apply for new Pie.

There's also a

copy of those instructions in this thread

. See post #107 and #108 (for confirmation).
