[muchbass]

Not dead at all. The developer has made some progress on the source code this month.

Whether that source code progress translates into something feasible and tangible for the device community is entirely a different story...

Well he probably wouldn't have made source code progress if there was no intention to make something usable for the device.

I still have (slim) hope that this will at some point be usable enough as a daily driver ROM.

Note

• This device has different names in different countries: J2 Prime; J2 Ace; Grand Prime Plus. As long as its model is SM-G532G/F/M/MT(/DS), this ROM is for you.

Working

• Boot
• Wi-Fi / Bluetooth
• Sensors (Prox, Accelerometer)
• Audio / Video / Media
• ADB / MTP (must turn on File Transfer)
• Brightness
• Camera (Front, Rear, Flashlight)

Not Working / Bug

• (NW) GPS (constant crashing) (Remove mtk_agpsd in system/bin if you don't mind)
• (NW) Video Recording
• (NW) Radio FM
• (NW) LiveDisplay
• (NW) Recent key
• (NW) Wi-Fi Hotspot
• -------------
• (bad bug) Phone randomly freezes, completely. You have to take battery out and in if it does so. Currently DKY.
• (bug) Snap - Camera app on LOS - breaks after you take a picture (the picture taken is still saved and viewable). Use 3rd party one like OpenCamera or Gcam 4.x armv7-a.
• (bug) SD card cannot be read by non-system apps (such as a file explorer).
• (bug) Bad battery life if RIL is not working. You can add into system/build.prop this

  ro.radio.noril=yes

  or fix RIL itself, but....
• (bug) RIL and Audio, only one can work. If you want RIL in this ROM, you have to disable Audio. Check the workaround below if you insist.

If you find any unmentioned bugs, mention me. Any logs of those bugs are appreciated!; but mentioning it with reproduction should suffice.

Workaround

As mentioned in bug list, if you want RIL, audio must be disabled.
Unhide this for steps and stuff

• Steps:
  1. Backup the folder /data/data/com.android.providers.telephony. It will be vital later
  2. Install ROM as normal, don't reboot yet.
  3. In TWRP, go to Mount, tick System.
  4. Press the home button, then go Advanced > File Manager.
  5. Locate to and find file /system/lib/hw/audio.primary.mt6735.so (if you mistap, tap the ... folder on top to go back).
  6. Rename it to anything else (I just add .bak, so if I want it later, I remove the ".bak").
  7. Now reboot and do setup wizard.
  8. RIL is still not working yet, but go on.
  9. If you have 1 SIM in, move ahead. If 2 SIMs, turn off both SIM's cellular data (In Settings > Data Usage), then set both SIM's preferred network to 2G (in Settings > SIM Cards).
  10. Reboot to recovery (Any of these: Power off phone then Power + Vol up + Home; adb reboot recovery; reboot recovery option in Magisk)
  11. Copy the folder in step 1 to /data/data
  12. Reboot now. Turn on cellular data and enjoy. (if you want 3G or LTE, change the preferred network ON ONE SIM ONLY. It will break if none of the 2 SIMs is on 2G)
• Additional bugs:
  • No audio, as said. This means no Media Recording/Playback as well
  • RIL will break if you install NanoDroid (even when your audio is not working)
  • VoLTE, Calls (because no audio)
  • (1 or 2 SIM in) RIL breaks after a few days (probably 2 or 3)
  • (dual-sim with 2 sims in) This is due to Hardware limitation: at least 1 SIM's preferred network must be set to E (2G) and at least 1 SIM's cellular data must be off at any time
• To revert back: Do step 3 to 6, but instead rename it back to audio.primary.mt6735.so, then reboot

Download

• ROM: https://github.com/almondnguyen/android_OTA/releases/tag/14.1-20201125
• Google Apps (pico recommended): https://opengapps.org/

Instruction

1. Install TWRP
2. IF YOU WANT RIL, SEE THE WORKAROUND ABOVE FIRST.
3. Format Data and System
4. Install ROM and Gapps, optionally Root (use Magisk)

Enjoy!
