hello installed the rom too so far everything works correctly but theres one issue i having. Its affects the Obb Folder. Ihave a game called Dead Trigger which needs access to the obb folder , which works so far but it kinda lets the OBB folder dissappearing and then theres a obb file which is 0 Bytes replaces the folder. I tried to fix it by removing the obb 0 byte file but it keeps coming back and crash the obb folder.

Weird behavior, I personally tried these games and they're working fine. Try to clean flash the ROM (formatting data) I guess.

New build is up.

2021-09-12 [douglas] [giza]

  • Fixed up wpa_supplicant config files.
  • Cleaned up wpa_supplicant service definitions (rootdir).
  • Kanged Wi-Fi HAL from the BQ Aquaris M10 (freezerhd).
NOTE: please, let me know if wifi drops are gone.
Great work as always, the build is almost stable!

The one issue that affects me is the inability to connect to hidden Wi-Fi networks. I can add them, but they will go to the saved networks afterwards and won't be seen in the available networks page.

I hope you squash this in the next build. If it's something wrong that I'm doing, I'd appreciate letting me know.

Keep up the good work! Thanks

I can confirm this. It works initially but eventually the obb folder becomes a 0 byte file. Also, Chrome isn't able to save to the download location and complains about not having access to the SD card.

@Rortiz2 I did a 2 days test with the new build and wifi disconnections are almost gone for me. I lose connection from my nas from time to time when streaming video using VLC, better test another player when I have time to see if there is some kind of buffer issue within the app.
Since Netflix and Amazon Video are working fine could be just VLC acting weirdly.

About battery time, I got more than a day of juice with about 3 hours of full hd streaming and a bit of navigation.
Not bad at all if considering the age of the battery and the deep sleep not working yet.

i tried it i wiped everything and reinstalled the rom , it still having those weird behavior.

Alright, I could experience this issue as well, I'll investigate it as soon as I can.
By the way, I did some progress with camera and now the device isn't crashing (and force rebooting) when opening camera. I'll keep you guys updated ;)

Code:
09-15 01:24:50.954  1705  1705 D AMZ-MtkCam/DisplayClient:  (restoreBufCount){#197:vendor/mediatek/proprietary/hardware/mtkcam/legacy/v1/client/DisplayClient/DisplayClient.cpp}[restoreBufCount] get_min_undequeued_buffer_count failed: status[Function not implemented(38)]

Awesome. Let me know if the issue persists with other players as well.

The camera seems to be working without problems after modifying lib3a.so with Ghidra (I just had to patch NS3A::AeAlgo::getRecommendCWTarget_v2p0 to always return 2). The video recording isn't working but fixing it will not be very complicated (since I had the same problem with my old MT8163 tab).

  • Fixed camera.
  • Fixed internal storage (OBB) issues.
NOTE: Video recording isn't working at all, it crashes with the stock camera app but it works with some third-party apps (such as Telegram).
NOTE: Let me know if obb issues are fully gone (I basically reverted the sdcardfs squash update). Try to clean flash the ROM as well before reporting if the bug it's still present.

Whoa, never thought I'd see the day the camera was working on this thing. Rortiz2 does the impossible once again. Great work!

    I just installed this for the first time ever on my douglas (bricked > downgrade > LOS > Profit). And I am kicking myself for not doing this sooner. The tablet is unrecognizably fast compared to the garbage FireOS! Thank you @Rortiz2 for all your hard work. This is really superb.

    That sounds like toomuch work. :) I was kinda hoping to get hw video for 720p60 videos in youtube cuz they seems to lag abit amd i am too lazy to switch it to 480 manually but i am pretty much content with the state of 15.1. Good work mate!
    Yes, indeed it is. We can only thank Amazon for not updating this tablet to (at least) Android 7.1. That could have made my life easier. Anyway, I'll focus on OMX once I fix these internal storage/external SD card leftovers and that USB connection error.
