Alright, I can confirm that it also happens in LineageOS 17.1, so not RR specific (probably?).

Edit: Hot damn, I'm not sure, but I also tried on Lineage 16.0, and it also happens.
I've tried it on my TB-8504X and it doesn't happen for me. Audio starts working when I disconnect the headphones. Which firmware are you on? Try S001031.

TB_8504X_USR_S001031_1912041525_Q12000_ROW

This is the version I'm currently use, but I use Lenovo tool to get back to stock, is that a bad idea? And I don't know why but Qfil refuse to recognize my tablet, so that's why I had to use Lenovo tool, does this tablet need some kinda of specific USB driver?

And when I back to stock, it work as normal as I want, plug in headphone -> headphone have sound, pull the jack out -> speaker have sound, on both RR and Lineage then speaker wouldn't have sound.

I'm not sure what could be causing it. It works fine on my device (in RR). Maybe a `logcat` will tell more...

Here is the log, I did exactly like this:
1. Turn on music on speaker -> Sound from speaker works normally.
2. Plug in the headphone to 3.5mm jack -> Sound stop from speaker, sound start in headphone (normally).
3. Pull out the headphone -> Sound does not return to speaker, stuck in headphone mode (even when I turn the volume up, it appear the high volume thingy which supposed for headphone), plug in headphone again don't make headphone have sound too.


And I'm back on RR right now, tested on RR.

Thank you, I'll try to compare it with my device.

@adazem009 , may I ask the exact specs of your tablet just in case?

Mine is TB-8504X, have sim slot LTE.

Snapdragon 425, 2GB RAM and 16GB of internal storage, 5MP back camera (I think there is a 8MP variant).

Are you running RR rom? IF yes can you please try some of the bug I encountered please.

Thank you in advance.
Sadly, no, I really needed calls so, I had to downgrade to los 16, tell us what the bug is, I will try to remember it from memory (I used this rom for about 2 months, so, yeah...)
Edit: I corrected a few autocorrect mistakes, sorry about that...

I have 8 mp varaiant , everything is working perfectly in RR rom, for me RR better than Los 16 and 17 due to smoothness and face unlock in RR.😊


Edit : Even RR fixed my null imei problem, actually in los 16,17 sim works but system shows imei no. Null.

Outgoing calls are working fine for me. Try to call someone in LOS 16.0 and check if your data connection during calls is H+ or LTE (4G). If it's LTE (or 4G), you're using VoLTE.

I did some testing and found these results... From Lineage OS 16, my current ROM
If the 'Enhanced 4G LTE Mode' is off, the calls don't work at all, even with and without internet/data, as soon as I turned on the 'Enhanced 4G LTE mode' the calls started to work normally, also my carrier only supports 4G (Jio), so, I think you are right about VoLTE, also, even in other devices, this is the same for all devices, for example on my secondary phone, the same thing happens...
Also, I don't remember seeing the 'Enhanced 4G LTE Mode' in any Lineage 17.x based roms for this device...
Edit: The connection during calls is always LTE, since my carrier Jio only supports 4G....

Alright, here go the list:
1. Plug in headphone -> Listen normally from headphone, speaker no sound (this is normal) -> Unplug headphone, still no sound from the speaker, replug headphone also make both don't have sound, only can fix after a restart.
2. Package installer sometimes bug out, cannot uninstall or install anything -> TWRP wipe davik/cache fix this.

I think that's it, the two most frequent bugs I met.

As far as I remember, I didn't encounter the first bug, but, I have encountered the second one a few times, my workaround was to clear the data and cache of the package installer, then disable it, force stop it, and then enable it again, this workaround fixed my issue

Alright, thank you, I think mine 3.5 jack probably went bad with the year, at least wireless earbuds work fine. :D

    Have to thank you again to your work, you're a absolutely legend for keeping our device has more life.

    But edit: After dirty flash, Wifi and Bluetooth dead again. :D
    That happens on some devices for an unknown reason. On my device it works fine, but only some people have got this problem. It's probably something related to the latest security patch because it happens on crDroid too. (it's another ROM that's coming today btw).

    Resurrection Remix the ROM has been based on LineageOS, SlimRoms, Omni and original Remix ROM builds, this creates an awesome

    combination of performance, customization, power and the most new features, brought directly to your Device.


    Many things that in previous versions were tweaked with mods, are now included by default in the ROM so, please enjoy!

    Special thanks to the LineageOS team, Omni team, SlimRoms and of course to all the supporters.

    Bugs:

    • Same issues as in LineageOS 17.1 builds - VoLTE doesn't appear in settings.
    • Double tap to wake (broken in all ROMs).
    • Screen recorder doesn't always work.
    • WiFi and Bluetooth don't work on SOME devices since July 2021 security patch (there's a high chance your device won't have these issues).

    @adazem009 @Hausemaster Fantastic job! I've loaded it on my 8504F.

    Only issue I can find was on initial start, I declined the face unlock, and that prevented my going any further. I rebooted, and reflashed, but it kept saying I needed app permissions...

    So I flashed LineageOS 17.1 (which has never worked for me - caused a boot loop), then re-flashed Resurrection and this time accepted face unlock.

    And now, it feels like I have a brand new tablet!

    Thanks guys!.
    You're welcome :)
    Next build is probably going to come next week. It's going to fix screen recording.

    I tried to install this but ended up in a bootloop stuck on the RR logo (for over an hour). I tried going back to stock using the Lenovo rescue tool, which mostly works, but the tablet no longer has any Wifi. Any suggestions? I'm hoping reflashing the boot.img would help but I can't find a copy of that file anywhere -- if anyone can provide that I'd really appreciate it... thanks
    i had faced similar problem( wifi mac address 02:00:00:00:00) when i flashed stock rom(through lenovo assistant) after a bootloop, than i again flashed custom rom(lineage 16 in my case) and wifi start working but wifi mac address changed to different one, than i again revert back to stock rom and everything working fine , i hope it will work for you, (currently i am using RR ROM).
