Can't activate bluetooth - LeEco Le Max 2 Questions & Answers

Hello,
it seems that on my brandnew X820 bluetooth isn't working. When trying to activate the switch remains grey and reverts to off after a few seconds. Also apps are unable to turn it on.
Unfortunately I did'nt check this with the original ROM. After arrival of the phone I put TWRP on it and then LineageOS. I tried a couple of other ROMs but bluetooth still doesn't work.
What can I try to check wether it is an hardware issue?
Any help is appreciated.
KR,
Bernd

BT freeze problem after update

Hello,
I have an xda prophet for quite some time now, with wm5.
I updated to wm6 and radio rom to the latest one.
After that I had problems with the connection to GPS module. I can see the module, I set paired device, set com port everithing's work fine, I recieve GPS data for a period of time (1min-10min), after that I loose conection.
I get an error that "com6 is stuck in a system call". Tried com7 same thing.
When this happens, I can not turn off bluetooth, whatever I set, led blinks like is on, status remains on, but it is not working.
After reset work's again. Sometime I get also "bluetooth hardware error" (if I keep insisting setting bluetooth after freeze) or "unrecoverable GPS error".
I tried these days changing radio rom to: Prophet_G3_G4_RadioRom_v2.61.21
and WM6.5, same thing happens.
Anyone had such experiences ? is related to rom updates or is a hardware mallfunction?
thanx,
Nemo

Well i would say try another ROM 6.0 or 6.1 as 6.5 is a beta platform and has many bugs
The good thing with 6.0 or 6.1 is that you can troll through the threads checking for a all working stable build
If the above don't work you could try flashing the nvid ROM this will downgrade back to original wm5 but also put everything back to original working order if not a Hardware issue
Thank you for the reply, I thought to try this and also to downgrade back to wm5. Meanwhile I searched this forum alot, and it seems I found a fix.
I edited the registry:
HKLM\Services\OBEX
(Change the "Keep" setting to "0")
HKLM\SOFTWARE\Microsoft\Obex
(Change "IsEnabled" to "1")
In my case the first entry was set to "1" by default, I changed it to "0"
The problem seems to be gone, I hope I'm not saying that too early, but yesterday I had GPS connected for a long period several times without freeze.
Thank you again, great comunity, great forum, loaded with valuable info.
PS. Admins, if you think this thread is useles please delete. Although I searched the forum alot before I posted, I did not found such problems. The fix I found was on a thread also BT related, but different problem.
So yes, I was too early. Problem still present. I will start downgrading later to see what I can fix. Any other ideeas ?

Cello T1144 Need help with ROM

Hello,
Recently I bought a tablet Cello T1144 v2 through ebay and it does not work properly. I can not connect to a wireless network. I try to turn the wireless settings on and see how the slide moves to "ON" and immediately turns "OFF". Also its sometimes reboots randomly. Before I decide that this is hardware issue, I want to reinstall Android, but I cant find ROM for this tablet.
I tried to contact Cello support and asked, but no luck -- they only said that I can send them tablet and they will reinstall it for charge. But it is very non economical for me. Maybe somebody had this tablet or can provide some useful links where I can find ROM? I would be grateful for any information about ROM for this tablet

Bluetooth Wont Turn On

Hi All,
Had this issue for a while, currently running LineageOS 15.1 but tried other ROMs too.
The issue is when I try and turn Bluetooth on the button turns grey and then after a while goes back to off again.
Looking around it seems other LeEco models seem to suffer the same issues (such as Le Pro 3).
I managed to get it working momentarily (60 seconds) by reinstalling the 30s firmware.
I checked the logs and noticed the following:
E/bt_btif_storage(14919): btif_storage_get_adapter_property: Controller not ready! Unable to return Bluetooth Address
E/BluetoothServiceJni(14919): adapter_properties_callback: Status 1 is incorrect

Click to collapse
Any ideas please?

Bluetooth disconnecting all the time

Hi, my mi 8 pro will not stay connected via Bluetooth to my car or galaxy watch, it seems worse after last update, my first question, is there anything I can do that can fix the issue, secondly does anyone know if flashing a custom rom will solve the problem, if so any recommendations.
Thanks
Same problem here. I did try to reset the network connections from the settings but that changes nothing.
