[Xiaomi Redmi Note 5 Pro Questions & Answers] lucius100:
My whyred RN5pro come with global rom miui 10 with android pie I think ?

I unlocked the bootloader and flash PE pie latest version, it required pie firmware, and I flash latest pie firmware from https://xiaomifirmwareupdater.com/firmware/whyred/

After usage for half year, I decided to use oreo rom, there's a few reason.

1. I thought always keep update will make it more stable and safe. But I was wrong, the more I update the PE rom, the more unstable it was. After usage a few days, it will freeze and need reboots, sometimes it slow on animation.

2. I need call recorder, but android pie restrict this function.

3. The latest build now come with wifi drop or something, sometimes my internet access is unavailable while my wifi was working fine.

After that I think a lot whether to use pie or oreo, and which custom rom suits my need ?

After reading and searching, and thinking a lot in these 3 days, I come up with a solution.

1. Because the pie keep get updating, it always got bug and some glitches stuff, and I don't have a lot of time and don't like to keep flashing new custom rom, I decided to use Oreo Custom rom final version instead.

2. After a lot of research I come upon RR, PE, havoc OS, liquid remix, lineageos, and decided on lineageos 15.1 final version as my custom rom.

3. Because I don't need a lot customisation, I think lineage os is the best for me, as I only need privacy guard, network traffic indicator, and stability.

So I changed to lineageos 15.1, here is what I do

1. wipe dalvick cache, data , internal storage

2. flash oreo latest firmware V10.3.1.0.OEIMIXM from xiaomi updater site

3. flash lineage-15.1-20180709-UNOFFICIAL-whyred.zip

4. flash magisk 19.3

5. flash opengapps pico

6. flash lazyflasher no verify opt ( ended up failed / error ) Because I read some user getting bootloop caused by encrypted phone or something, I don't know about this part, so I just flash lazyflasher as the instructions said for uncencrypted phone ( ended up failed / error ) ( I don't know if my phone encrypted or not, so I just flash it as additional file)

7. reboot, after getting in, it shows android encrypting, and reboot again, after a few minutes, I thought it stuck on boot loop, but finally it gets into the welcome screen. I tried reboot a few times to see if it stuck or not, but it was working fine. Tested the rom 24 hours by now, and everything seems to work fine.

What I want to ask is,

1. Does my step on changing from pie custom rom to oreo custom rom correct ?

2. lineage-15.1-20180709-UNOFFICIAL-whyred.zip Is this the final version of oreo lineageos 15.1 whyred custom rom ?

3. Sometimes I saw my sim network bar gone completely, but I can make call and check balance, and in the sim status, it show -100dbm and 99 asu. Is this normal ? Or is it because I flash wrong firmware or something ? Or is it caused by my area unstable tower network so the bar completely gone ?

4. Should I use pie or oreo firmware in this custom rom lineageos 15.1 android 8.1 ? Or it's irrelevant because the firmware is flashed by the lineageos custom rom ?

5. Do I need custom kernel ? And what's the best custom kernel for android oreo ?

Other than that, I am satisfied with everything it offers. Thanks for reading and replying.
