[Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot] chsaiteja98:
Evening.

Hi, I am a long-time custom ROM user.

Have been flashing custom ROMs since my first phone(Lenovo k3 note)

These are my thoughts on this MSM Xtended rom, based on 4 hours of usage.

Will write again, after a couple of weeks with more insights.

I bought poco x3 6Gb 64Gb Indian variant, I believe that this device has a code name "Karna".

Downloaded all the ROMs from xda and started flashing them one after another just for the customization options I needed.

I am a huge fan of Resurrection Remix ROM, as it contains a good balance of features and options.

But it is not available with android 11, and I think MSM is the close second to it.(Good Job MSM Team).

Okay, To install the custom ROM I followed this procedure, anyone doesn't know how or has any doubts you can review this.

And help me if I did any mistakes that could cause any more bugs.

Installation Steps I Followed.

1. Signed in with MI account and unlocked with mi unlock tool on pc.

2. Went to fastboot and flashed the TWRP and booted to TWRP. (Version 3.4.0)

3. After flashing TWRP, flashed the "dm verity" zip file,(don't know what it does but followed a video tutorial on youtube)

4. Downloaded all android 11 ROMs on xda for poco x3, most of them can be flashed some didn't flash, I think due to device compatibility issue.

5. Followed the guide and tried to wipe the data, but I only got these options in the wipe menu of TWRP.

1. Dalvik

2. Data

3. Internal

4. Cache

5. Sd-card

6. Couldn't find the system or vendor as mentioned in the guide.

7. Thought this was an error and tried twrp 3.4,twrp 3.4-15,twrp 3.5 but still faced the same issue.

8. Then tried orange fox recovery, here also there is no system/vendor/product menu to wipe.

9. So wiped Dalvik, data, internal, cache, and flashed "Xtended rom" and "Magisk 21" it worked with these specific errors.

1. "couldn't mount /system-root but ignoring"

2. "couldn't mount /vendor but ignoring"

3. "couldn't mount /product but ignoring"

10. Worried it might cause some errors, but rom booted up and every option worked.

Thoughts on ROM:

1. Drained the battery and started charging.

2. Switched off the device and charged, but there is no battery indicator while charging, only shows poco logo with an unlocked icon on top. (Is this normal or a bug?)(Issue)

3. Switched on and charged from 30, it took 2 hours to charge the phone till 100. This is not good, don't know if this continues but in MIUI it only took 1 hour 30 minutes to charge from 0 to 100. (Issue)

4. No Google camera as the default cam, like in arrow os and pixel experience.May include it in the next build. (Request)

5. the x-home launcher crashes when I click on the styles and wallpapers option(Bug)

6. Great to include simple gallery as the default gallery app, I have been using it as my default gallery app for over 6 months(Thanks)

7. The restart menu is black when my theme is light, is this an issue? I think it should be consistent with the system theme(Issue)

8. The advanced restart menu items are crammed too much closer to read their text, why not make each row have 2 buttons and increase the size of these five buttons(Request)

9. If we can dirty flash latest rom, then why add a feature to settings to auto-update or something? (Request)

10. Went through the X-tensions menu and have no idea what half of them do, just configured the features that I needed, but I think this setting UI should be easy to understand. (Suggestion)

11. I prefer to use this rom, compared to other ROMs, I mean I like arrow and pixel plus roms, but they are too stock for my use case and I have been used to resurrection remix features for a long time in my old phones. (My history)

12. So thanks for developing this rom for poco x3, I have been trying to create ROMs for a long time, but couldn't wrap my head around it, i am a java programmer BTW. (Thanks)

Will update this post in 2 or 3 weeks. A lot earlier if face more issues.

Thanks for the Rom again.

Evening.
