LineageOS 17.1 - Xiaomi A2 Lite - Development Only

[yamaha77]

Very interesting!
Thank you!
Good job!
As far as I understand, the ROM is stable?
Or are there still have bugs / problems?

---

And another question: which TWRP should I use?

Hey, dear Reujea0. Would you mind if I ask you about Los 18.1? Is there any possibility of seeing it soon, depending on your previous messages mentioning about building it already?

Looking forward to hearing from you soon. Thanks for your efforts.

The rom is stable, nothing major, just have to toggle a switch when using gcam

Hello, sorry, I haven't had time to really look into hte building of it, had some issues but did not really investigate them, os I did not make any progress. Right now, the build is at 94% completed, will test it and if it works will publish it tonight. You can quote me on that.

 

[reujea0]

If I end up publishing los18 for hte phone, I will stop providing OTAs for Los17. Also I have decided that I will require a clean flash of los18 and not provide it as an OTA upgrade from los17. This way many issues around migration should be solved

I could use some help. I flashed the image to my phone, but screen stays black after reboot from Recovery.
What i did so far was as followed:

1. Went to options in the normal system, enabled developer mode and usb debugging.
2. Reboot to fastboot and used the command "fastboot oem unlock"
3. This cause a factory reset, i wen again to the options and did step 1 again
4. Entered fastboot again and booted the twrp image
5. flashed twrp on the phone as written here (exept the Magisk part):

6. Reboot into recovery, everything nice till here
7. Wiped the phone and installed you latest linageos version
8. If i reboot now into recovery, the lineage recovery appears. If i reboot into system, first the android 1 screen appears and afterwards screen keeps black.

I dont know what to do anymore. What did i do wrong? There wasn't any issues during flash of OS...
Thanks in advance!

EDIT: When i boot the twrp recovery via fastboot again and from there normal reboot recovery i get the LineageOS recovery.

Which twrp do you use? If you used "dees-troy" as the step 5 suggest you to do, that may be the only reason of your problems.
Please use either offain twrp or there are newer ones that you can find on xda. I recommend you to use this;

[RECOVERY][3.5.2_9-2][Mi A2 Lite] Unofficial TWRP recovery for Xiaomi Mi A2 Lite

When I use Offain TWRP PC output is like this downloading 'boot.img'... OKAY [ 15.830s] booting... OKAY [ 0.748s] finished. total time: 16.578s and then phone reboot to stock Android When I use TWRP from this thread PC output is same but phone...

Hi,

thanks for the quick answer. No, actually i use the "twrp-3.5.0_9-1-daisy-unofficial"

The problem is, there are 20 tutorials how to install and with that 20 different ways. Every tutorial missing out essential parts and i'm a little confused.

Okay than you miss the reboot to recovery step I guess.

Now as you use the correct twrp, I can say, after doing step 7, do what I say. (At step 7, you should also install twrp.installer)

Step 8- go back. And then press reboot. Change slot( if you're at slot 'a', press slot 'b'. Vice versa)
Step 9- now press reboot to recovery.
Step 10- if you will install gapps and magisk, you can do it very now.
Step 11- reboot the system.

Is the flashing prozess of TWRP even right? Do i have to flash it via install or via ADB sideload? Or is that the same?

EDIT: The way you suggest doesn't work either. I switched and afterwards rebooted the system. Screen stays black. But the phone is acually on, because PC tells me something is connected.

I install it within TWRP, never used sideload.

I mean installing TWRP, or does that even matter? Because after i flashed LineageOS the recovery comes from the OS, not TWRP anymore. Maybe the bootloader is damaged, because i did something wrong?
Also do i have to do the Encryption? One guid says yes, the other doesn't mention it.

MAybe an important hint is that i upgrade from stock Android ONE. Maybe thats the problem?

Let me sum up the process which will probably answer your all questions.

Once you opened the bootloader and flashed TWRP image successfully and saw TWRP screen on your phone, unplug it from PC.

IF you will install a custom rom, than
1- format data, type 'yes'. Reboot to recovery
2- advaanced wipe( everyting except sd card) (ı assume you should have put custom rom file and twrp.installer.zip to your sd card)
3- install custom rom and twrp.installer.zip(choosing to upload from your sdcard, you will be able to see them)
4- go back. Press "reboot" but don't reboot anything. From reboot menu, change slot(if you're at slot 'a', change your slot to 'b', vice versa)
5- now you can press reboot to recovery.
6- once recovery(twrp) opens, you can install gapps and magisk.
7- reboot the system.

Some roms require forced encrptions, you can follow what the builder of rom says.

Nope, it has nothing to do with coming from stock rom. It's actually indeed recommended.

Got it fixed, many thanks for your help!

Flashing failed completly, could repair it. What do i do now?

What happend: I bought a used Mi A2 lite with stock Android 8. Because i already used LineageOS and really love it, i want to continue to use it. I did the flashing process a few times wrong. After the help of a very kind user i did it as it was...

Does anyone know the procedure to install Gcam? Or it comes with the rom?
