[Letv Le Max 2] Stuck in Headset Mode / USB-C file transfert not working - LeEco Le Max 2 Questions & Answers

Hello,
I have a small problem concerning the USB-C port.
After connecting my bluetooth earphones, the terminal was stuck in headset mode. I tried to format data, to install again the rom, I made a factory reset, I tried different rom AOSP ... nothing
When I connect wired headphones, the sound works but when I disconnect them no sound works (phone calls and media for speakers or earpiece). I know the earpiece and loudspeaker are working because I tried SoundAbout under android 7.1.0, but this application does not work with android 8.1.0 or 9.0-Alpha
File transfer does not work either, but when I connect my device fastboot, adb recognizes it, when I connect it via android, only charge works.
I think the problem is related to the USB-C port, I cleaned it but it does not change anything ...
Maybe there is another solution that I have not explored yet ...
Thank you for your help.
Best regards
(sorry for my english)
Max.
The Max 2 X829 (treblized)
Android 9.0 alpha (AospExtended-v6.0-x2-20180908-1833-ALPHA)

Hi,
I downgraded to Android 8.1.0 [AOSPExtended [treble] V5.7-official] then I rebooted the system with the charging cable plugged and the sound came back ... weird :cyclops:
But If I reboot without the charging cable, the terminal stays into headset mode...
Data still not working
I don't know why ?
Someone get an idea ? What is the problem ? Any solution ?
thanks

Hello
sorry for a bit of necro
I also have the problem.
I use Audio Router from playstore which works like Sound About but is compatible with 8+ Android.
I also have problems that appeared all of a sudden at the same time:
- same faulty sound behaviour
- usb mtp/adb not available (under recovery and under Android)
- It also seems that my battery will not charge as fast as before though Quick charge is enabled.
pluging/unpluging will not bring the notification to modify the usb link behaviour.
I also tried enabling/disabling usb debugging options...
This happened after trying/flashing many roms so I don't really know which one would have caused evil :/
Do any treble rom could harm the device like this by altering the vendor partition or has it nothing to do with it ?
about usb under pie roms :
The options are greyed under Usb Preferences.
In developer mode, changing the default usb behaviour does nothing.
I have tried 2 USB C cables.
Both are working with my X820 only in bootloader mode.
And both are working fully with my second LeEco (x525).
So i don't think the cables are faulty.
And as it is working also in bootloader mode I suspect there is some lockdown somewhere hidden in my partitions.
But I can't find anything.
I also fully restored the X820 to stock and the problem remains.
under eui roms :
Same problem
No usb configuration available
If anybody could help that would be awesome.
thanks in advance

I would recommend you to reflesh phone with qfil.

Thanks for replying.
I have already done that (full qualcomm reflash with FlashOne & QFil image).
The problem still occurs.
This is very strange behaviour...
The phone is pretty new and I did not make it fall or whatever missuse.
The usb-c is still working in FastBoot Mode (but not mtp/usb file transfer nor usb debugging/Adb) and I can still charge the phone when not using it.
And about the audio problem it can be fixed with an app (audio router/sound about/...) so I am pretty sure it is pure software issue but I can't find any more information about this.
Is there any other system internal partition or else that is not flashed with every rom (other than vendor) and that could be different amongst the x82x devices ?
I have also tried flashing some modem files (not all) maybe this can be linked to this problem ?
Thanks

I am not really sure because I installed many roms for geekly testing purpose
And I can't remember exactly since when It happened...
I ordered my phone from China so I got a chinese eui and modem version but I don't remember which modem version it was...
though I am not sure it can be important or not here...
Currently I went back to SmallEui by Aurel.

This sound exactly like the problem I have.
I am sure it is not hardware related. I even replaced the usb port/flex cable.i don't know which ROM brought me to this stage. Maybe it was linage 15.1, build 20181201, but I don't think it's linage's fault. Because flashing an other ROM doesn't help.
Is there any partition that is not touched by flashing qfil zip file?
Maybe someone can provide twrp backup of all partitions that are reachable by twrp. Hopefully we can find the wrong part this way.

So yesterday I flashed again with qualcomm qfil (2 or 3 times) and I finally got back the audio, usb (debugging, mtp and charge).
I do not understand why but the at 1st attempt the audio problem was still here
at the second attempt the audio problem disappeared but my internal storage went partitioned down from 64 Gb to 16 GB
and finally at the third attempt It worked though I had to perform a final factory Reset from Android Settings because the internal storage was filled up to 50 Gb with leeco default garbage....
Everything looked good then and I was happy at last!
But then today suddenly it stopped working again...
I don't know what exactly is in cause...
since yesterday
- I played around with the usb-c / jack audio adapter
- I restored my apps
- I plugged the phone in another usb-c power cable (with magnet pin)
I will try again to fully restore and see what exactly is in cause of the problem...
The other Usb-C seems to be problematic though I am not sure it is the only one to possibly cause the issue....

[Q] USB data connection not working at all (CM 10.2)

Hi guys I'm having an issue with my GS2 i9100 after installing Cyanogenmod 10.2 using the installer on their site, I thought everything was great until i realised for some reason my phone refuses to display its storage on my windows PC, I've tried changing the different modes in the storage settings on the phone, such as MTP/PTP/Mass Storage and i've tried uninstalling and reinstalling the samsung usb driver via Kies but I still can't get it to work, is there an option I'm missing out here or is the rom at fault?
It charges perfectly fine but I am not getting any kind of prompt from either the phone or PC to activate the storage so I can copy files too/from it, it's getting quite annoying as their is alot of music/pictures/videos I want to put on the phone.
Clean install of stock to test before anything else.

Would it be safe to flash the stock rom using CWM6 recovery? as any tool that relies on a USB connection to the phone won't work.
Wanam has a thread in one of the Development sections with CWM flashable stock roms. I'd also be testing it with another PC to rule in/out something PC-side (if you haven't done so already). You need to be methodical with stuff like this - try stuff that rules in/out different causes.
Edit - You could also just take the punt it is the USB board in the phone on the fritz & replace it regardless, which is very cheap & easy to do if you're somewhat handy. KeithRoss39 has a guide in General (search for 'Replacing USB charger board') which has all the info you need if you decide to do this (will cost you a tenner).
In trying the things I've mentioned so far, that's what we're trying to ascertain; whether the board is faulty or not (common S2 fault, almost always shows a few faults but works OK in other ways). Put it this way, if you try those things I've suggested and you're still seeing the same, it's almost certainly the USB board.
In the meantime, use WiFi to get stuff off/on the phone if you need to (plenty of apps on GP enable this if you've never used it).
Sorry for the incredibly late reply, I've changed phones since, but I wanted to update this thread anyway, it turns out re-flashing cyanogenmod after replacing the pcb fixed the issue completely, installing it when i had the dodgy usb pcb must have made it not properly install the USB drivers or something

USB C audio not working on Lineage OS 14.1

Hey guys! I'm having issues with the USB C audio port after installing Lineage. Here's the problem and what I've done so far: The USB C earphones that came with the phone are not recognized when plugged in. I had used them with the stock ROM and they worked fine, that was until I flashed Lineage on my phone and now the earphones don't work. I went into the developer options and selected the USB port to be (audio source) and also disabled/enabled the automatic USB audio rerouting option under [media]. Neither option helped whether I enabled or disabled them (rebooting in between changes). Now, the port works fine if I plug in the USB C-to-3.5mm jack adapter and either a speaker or earphones on the adapter. The audio signal is fine then, it just doesn't work if the earphones are type-C themselves. I also tried going into the Lineage OS OTA update option and updating the OS from there to maybe solve a firmware issue, but the update always fails, stating that I have to check my internet connection. This happens on both Cellular signal and over Wi-Fi. So, I'm unable to use my earphones, AND unable to update Lineage. Any ideas? I appreciate whatever help you can provide.
use other roms

I've checked the info on the other ROMs and it seems each one has its own issues with bugs on Nougat versions that need ironing out. I think I'll stick with Lineage OS for now, unless you guys REALLY suggest I switch to a different ROM for stability, support, etc.. The only thing that kind of worries me now is the update fails, I don't know if I'll be able to get updates on the OS. I've never flashed an update over an already installed OS. Is that possible? Say I go on the website and find an updated version of Lineage (once released) Can I download it and update over TWRP? or how would it be done?. Sorry if these are Noob questions. Thanks in advance for any help.
Same problem with earphone USBc3 not working
I have the same problem with my Max 2 after installing an update around 27 July. The earphone is not detecting, you only can use the bluetooth.
Heyyo, try it with the LeEco logo facing backwards. Oddly enough for Nougat ROMs the USB type C CDLA headphones seem to only work properly with that logo backwards... Might be a byproduct of no blobs from LeEco for Nougat but I could be wrong
Hello,
I had the same issues with newest versions of this ROM. I have solved (for now) coming back to 14.1-20170721 version; after reinstalled this version with TWRP over the newest the Leeco headphones with USB-C plug started to work again.

I also tried downloading the latest nightly manually and using the data/data/org.lineageos.updater/app_updates directory to update, but it failed as well. My last resort was to try to update by flashing from TWRP in recovery, however that ALSO failed, I got an error message saying I was attempting to update over incompatible data. So, I'm unable to use my earphones, AND unable to update Lineage. I'd rather not have to factory reset, but do you have any ideas? I appreciate whatever help you can provide.
CDLA has been somewhat problematic under various Noguat ROMs for awhile now. Ex. audio works on them with the most recent Resurrection Remix-Nougat build, but they no longer respond to mic button presses.
I'm sure it will be fixed relatively soon, but it's an annoyance for now... ?

this is really sad and still an issue with latest version :/
Sadly this does not work under 14.1-20180304

PC does not detect Xiaomi Redmi Note 4 (even on TWRP)

Hello
I made a thread on reddit in the subreddit of my ROM (/r/LineageOS/comments/cccbtu/pc_does_not_detect_xiaomi_redmi_note_4/) regarding my issue and they recommended that I come here (I hope that's the right place.)
In summary, the notification that usually shows when I plug in my phone, to change the USB configuration from charging to MTP, does not show.
I've tried everything I can think of (different ports, PCs, cables, etc.) and nothing seems to help.
"adb devices" shows no devices both on normal boot and TWRP. The only thing the cable does is charge.
I'd be very happy to fix it.
Thank you!
First it's a software issue so the hardware is fine
Second i suggest getting an sd card with the official stock rom on it (version 10.1.1.0) to fix the reading error since it can't be readed even on twrp
If the problem still presists
I suggest to change the cable or the phone socket
Try another cable then see

Poco F1 Bricked

Hello,
I am currently in a dead end with my Poco F1, and would like to check with you before throwing it away.
I was using my Poco in version 12.0.3.0 with TWRP installed and root with Magisk. Due to the last days errors of apps that shut down when opened, I decided to reinstall the system using TWRP, but I made a mistake and installed version 12.0.2.0.
I don't know what installing this version did, but now the mobile isn't starting MIUI anymore, it's starting by default TWRP. Furthermore, something has been changed in the TWRP version installed that touchsreen it's not responding, so I can´t use.
The problem is worse since, for a long time the transfer of files to a PC via USB cable isn't working on my Poco, so Windows is not able to detect the mobile in fastboot mode either. I tryied reinstalling drivres in many ways, and still not working. The poco charges perfectly, so I don't think the problem is the USB conector, maybe is a motherboard related issue, so changing the connector I don't belive will solve the problem
Recap:
- I can't start MIUI (the version has been corrupted).
- I can't use TWRP (it has been corrupted and the touch screen does not work).
- I can't install from fastboot (Windows isn`t detecting the Poco with the cable connected).
- I don't think changing USB connector solve de USB data transfer problem.
Any ideas or should I throw away the smartphone?
For me it's a real pitty, because I don't like the new Poco F3 or others phones on the market, most of them don't have 3.5mm jack or microsd card slot, and are bigger, heavier and more expensive than the Poco F1.
Thanks to everyone.

Hello,
The issue with error of apps was probably due Webview which Google pushed an update and fixed it. For more infos read here.
Now, to the current problem...how did u flashed previous version? Clean installed or Dirty installed?
What Desktop system do you use? AMD or Intel? Your PC can detect the device while you are on TWRP? Do you have twrp.img on ur device so you can reflash it via TWRP?

Thanks for your answer.
I noticed that the issue with the apps is due to webview after breaking my phone, next time I'll think things twice before flashing anything.
I did a dirty installation, I thought I was installing same version (12.0.3.0), but I was flashing 12.0.2.0 on top of 12.0.3.0 without cleaning.
I tried both desktop systems: my laptop with an Intel CPU, and a PC with AMD Ryzen 9 3900X. I also tried 5 diferent USB-C cables that are working perfectly with others Android devices. When I look for new devices in the device manager of windows I can't tell any diference on listed devices with or without connecting the Poco. As I said, maybe I have some hardware issue in the phone, because file transfer was not working for many months.
I can't install anything via TWRP because touchscreen don`t respond to mi fingers... I remerber that this happend to me years ago when I installed a wrong TWRP version, but don't know if that is the problem.

Well, somehow you need to manage to flash MIUI again via TWRP or Mi Flash Tool.
Perhaps if you redownload latest twrp.img and latest official miui 12.0.3.0 and transfer them to USB OTG or external SD Card and then put ur OTG or external SD Card to your phone and flash it from TWRP. Since you was able to wipe system as u said before you will be able to flash twrp.img into "Recovery" make Clean Install (according my guide) and flash MIUI.
I'll try if connecting something via OTG make the phone responds, but the main problem with TWRP is that appears to be corrupted or something. I cann't use it because touchscreen don't responds to me, and nothing happens either if I try to use it with volume+ and volume- buttons, I see TWRP but I can`t interact with it.
Thanks again for your patience.

I tried using OTG cable in TWRP and nothing hapens, TWRP don't respond.
Seems that I'm in a dead end, I ordered an USB PCB spare part to try if is posible to repair the USB data transfer connection replacing it, becuase looks like is the only way I have of flashing a new clean rom.

If you have AMD system try the AMD Fix in my guide. Also try this guide to install drivers.
Finally I could solve the problem.
I bought a new part of the USB port PCB from aliexpress, I ordered one that claims to be original for around 15€, not the 2€ ones.
I replaced it and the data transfer is working again, so I could install the ROM via fastboot from my PC.
I don't beleive that the PCB I replaced is original, but works like it is, phone charges properly and seems that didn't loose signal.
Thanks to everyone.
