[Google Pixel 2 XL Questions & Answers] hamisgood:
I tried uninstalling certain system apps via Titanium Backup such as Play Movies & TV but to my horror, PlayStore reinstalled them immediately.

It's not a huge deal but I dislike seeing apps on my app drawer that I will never use. Alternatively, I could freeze it but I rather free up the space.

Has anyone had any luck in permanently uninstalling system apps?
[Google Pixel 2 XL Questions & Answers] Badger50:
You could try using your root explorer type app and delete the apk. Should be gone after a reboot.
[Google Pixel 2 XL Questions & Answers] Zorga:
I always use solid explorer to do that. Works every time
[Google Pixel 2 XL Questions & Answers] marbertshere:
I have the same problem. Have you guys been able to use a file explorer to do it? Root Explorer just says that the delete fails and Solid just hangs during the delete process. Anyone figure this out?
[8525, TyTN, MDA Vario II, JasJam ROM Development] finisterre:
Ever since this morning my Vario II (running HTC WWE WM6) has been putting up this screen everytime it tries to get a data connection?

http://finisterre.googlepages.com/VidyaScreen001.jpg

Any ideas what might have caused this, and what may fix it? I just seem to have to press OK without putting in a User Name, Password or Domain, but it's very annoying.

[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] Hellrazoraj:
[MENTION=7021712]FoxBob79[/MENTION] You will get error 7 as the internal storage is encrypted in Oreo. For this. I downgraded to nougat (clean & lock bootloader) then flashed the twrp of steadman. Once inside the twrp.i wiped everything that includes internal storage also. Connected my phone back to my laptop & transferred the lineage os build & flashed it. Flashing does take some time so keep patience. Once done please restart, but then comes the problem the phone doesn't boot into lineage. I tried these steps with RR mix & Dotos & had booted successfully in it.

Let me try this then.. which version of gaps should I use?? I don't have the magisk/supersu with me
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] zeyaan:
Try with the latest magisksu if not let me know there is a specific version which worked with op5. SuperSU had issues. Also be sure to follow the procedure correctly else it won't boot.

[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] zeyaan:
[MENTION=7544198]Hellrazoraj[/MENTION]

Did you do a clean install? I mean wipe system in TWRP and install? Try again it should most probably work. And are you unencrypted? With dm-no-verity.zip?

You need to 1st formats data from internal storage, flash dm-no-verity.zip. flash magisksu. Boot up to system.

The reboot to recovery and flash ROM+gapps(open is my personal preference)+magisksu.

This should do the trick.

Please try again and report.

Yes, these are steps that I am using

1.clean & lock bootloader flash nougat ROM

2. Setup the nougat ROM

3. Turn off, boot into bootloader. Use dead man's twrp

4. Once booted into twrp, clean all including internal storage

5. Restart the phone in bootloader

6. Connect phone to your laptop, transfer all the files you need.

7. Flash them

8. Restart.

So pls check & let me know does it boot for you or not?? Cause for me it didn't, it gets restarted but all I see is my screen flashing & nothing

2nd post doesn't matter anymore..the developer has stopped the developments..it's the other devs who r creating the lineage os ROM & the original dev had used other kernels & not the real mi a1 kernels
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] veloz46:
Effectively!
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] zeyaan:
I guess your missing out on one important thing.

Once your on nougat, you will need to unlock bootloader and then boot into TWRP. Try 3.2 or official 3.1.1. also you need to be decrypted. To get there you need to format data partition and the load ROM again from PC n flash. While flashing ROM, yu also need to flash gapps n magisksu.

Btw havnt seen anyone make dm-no-verity.zip for our phone. If that's done I am 100% sure roms will boot up. As most of these roms are enabling force encryption.

Sorry cannot trust myself as my pc broke down and will take couple of days before I can try n find solution myself.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] Hellrazoraj:
The DM Verity doesn't matter to be honest..I had formatted the internal memory & flashed the RR remix os & dotos using the same method & they booted without any issue.. yes but once they booted none of the things worked.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] zeyaan:
I just read in another thread, a couple of devs managed to get kernel booting; however, encryption is the problem. I just hope we find a solution soon. Cannot wait to try roms. Honestly, stock is too buggy for me.

It's a near stock rom, usually with kernel improvements like KCAL and substratum support built in. It's also more customizable because of these tweaks.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] t0per666:
You are the kind of people that don't understand how custom rom works and don't think about what you're saying. Do your research and stop posting useless things.

And all the people saying "ow you bought an android one/stock android phone and still wants custom roms/LoS/AOSP/MIUI" you are dumb!!! Vice versa for Mi 5x "ow why did you bought mi 5x if you want stock android why not mi a1" easy it is not available in their country!!! CUSTOM ROMS is much more updated and optmize than stock ROMS!!!

Stock rom updates once a month! Or even a year!! Before you get updated versions! CUSTOM ROMS updates weekly or even daily! And have more optimizations and tweaks!! And a ADD A CUSTOM KERNEL!!! MORE BETTER!!! Geez! So STOP IT! and do your RESEARCH! before commenting. #PeaceOut! ?✌️

On some ROMs with Le2, the kernel would needed to be set as permissive for IR to work.

Secondly, about fingerprint scanner there's a patch for goodix available in the Redmi 3s and Redmi note 3 forums. They might be of some help.
