I've a "stupid" question in regards to LTE, voLTE.

Here's the scenario:

At current times I'm working from home where I only have 3G/UMTS. The other day I was in an area where I had LTE reception.

I needed to make an international call (Austria) that got immediately interrupted. Being surprised, I tried US to call, same result. Tried a national call - worked.

I checked my provider settings in my account making sure I have not unchecked international calls. All good.

I called the provider asking whether there is a problem in the area. All good.

I then checked my phone and switched off voLTE, which is on by default. Obviously the phone then used 3G and international calls worked without any problems.

The provider is WinSIM (Germany), the network Telefonica/O2. Actually voLTE and even WIFI calling should work.

Is anybody having a technical explanation, what is happening?

It seems that everything is dead, latest custom (RR) is 7.1.2 and the finger print is not working. That's really sad, cuz i can't find pro anywhere to buy :/ and I really like this phone
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo [MENTION=4520958]origin_de[/MENTION] , hmm, I think the issue there is maybe APN settings as WinSIM probably doesn't have any APN settings in LineageOS. I would recommend to try flashing updated APN settings from Google. If you check my first or second post you'll see a link to my mods and tweaks and the readme there has information about how to use it.

Sorry to hear about that [MENTION=2529763]unfire[/MENTION] . I remember before a guy asking about how to get the kernel source code working on custom ROMs and I gave him a basic run-down on what to do, but tbh I have no idea how far he got with that. I'm guessing by you saying the last custom ROM was RR Nougat that he never finished it I guess... Like I said though since I don't own an x900 I don't have any plans to work on it as that would require a heck of a lot of testing and fixing in order to get it working correctly and something that would be a nightmare to do on a device bring up when I couldn't even test anything myself.

With the LeEco Le Max Pro (x910) that has a SnapDragon 820 though and a mostly complete source code release thanks to the Le Pro3 (zl1) containing source code to it as well in their source code release I can get that working on our msm8996 kernel easily enough and it mostly works correctly too.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] origin_de:
[MENTION=6235294]ThE_MarD[/MENTION]: Thanks for your reply. Sorry I didn't mention that flashing the APNs from your 2nd post was one of the things I already did - just to be sure. Nevertheless WinSIM uses APNs from Telefonica/O2. When it comes to APN setting they directly point to O2 APNs.

What really puzzled me was that I could do national calls, but not international ones.

Have done some google research and found other users seeing similar problems with other providers/phones/Androids.

But I didn't find an explanation of the root cause.

Wi-Fi disconnects when phone is locked.

Hello, good people,

I installed LOS 17.1 (the official one from 22.April.2020) and GAPPs from 06.May.2020 (Full version) on a non-treblelized device that was running Nougat. I've got a question, but before that...

Wow! My phone has never run so smooth, so fast, so cool and the battery has never lasted more than a day with normal usage. A huge thank you, ThE_MarD, it feels like a completely different phone than before when I was running Resurrection Remix 5.7.4 (Nougat). The day I installed LOS 17.1 I tinkered with the phone for like 4 hours SOT (restoring backups, installing apps) and still had 47% battery when I was finished. Not a single hiccup with the installation or usage, pure bliss :) (just Google Photos crashed on first run, but was fixed after an update). Awesome job, mate.

So, back to my question. I noticed that my phone does NOT stay connected to my WiFi when the screen is turned off. Everytime when I unlock my phone, either with the power button or finger print, the very first second I can see NO WiFI icon in the taskbar and the WiFi connecting about 2-3 seconds after that. I'd like to think that this behaviour is a feature and not a bug, maybe the phone uses less battery when the WiFi is off, I don't know, but it leads to another "problem" - my phone does not perform a backup when I'm charging it, nor does it do app updates if there are any in the Play Store, because "it's not charging and connected to wifi at the same time". If I leave the screen on while charging my phone - the WiFi stays connected and a backup is performed as per system settings, the Play Store updates my apps as well.

I just want to know how to make the WiFi stay connected when I turn the screen off. There is a setting in the Developer Options about WiFi throttling that is turned on by default. Could that be the problem?

Hello ThE_MarD,

I quote my note about the APN and the signal quality because I posted it when a corrupted release was builded and perhaps you didn't have the time to react.

Now that it's quieter, maybe you could give us your opinion about this ?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, a new test build is going up! It will be live within 30 minutes of this post and link as always in the first post. lineage-17.1-20200511-UNOFFICIAL-x2 has a permanent fix for front camera green tint in Google camera mods by hex editing the camera ov8865 blobs for black levels. This is inspired by the fix that nullbytepl made for s2 which translates perfectly to x2 and zl1. :good:

[MENTION=4520958]origin_de[/MENTION] hmm that I'm not sure of then sorry... I guess for now your best option is to just disable VoLTE. Sure, call quality will go down a little but at least they'll always work.

[MENTION=8125493]tr0ubles0me[/MENTION] that's good to hear how smooth LineageOS 17.1 is on your x2. :good:

As for the behaviour? It is indeed to save battery life. While charging though I believe it should stay connected. My x2 does the system backups when I plug in my x2 and have it charging. It usually only does it once a day or every other day for me.

[MENTION=1692540]jean_htc[/MENTION] sorry I must have missed your question before. Signal should have zero differences between Android 9 and 10 as we are using the exact same IMS, QMI and RIL stack. The same one we have been using since Android 8.1 tbh from Gemini (Xiaomi Mi5). So I'm not sure what to tell you about that sorry as nothing has changed in our device tree that could affect signal strength.

[MENTION=2529763]unfire[/MENTION] I would recommend keeping an eye on this thread and the guy who created the thread as he just mentioned he got his source-built kernel for x900 working and is going to try building LineageOS for it. :good:

Heyyo, so some new news on my replacement parts! I finally received my battery! My "totally not fake" 4500mAh/6500mAh battery... yet the one I ordered from AliExpress was the "LOSONCOER 4800mAh LTH21A Good Quality Battery For Letv Le MAX 2 X821 X820 Le MAX2 LeMax2 X822 X829 Phone Battery+Gift tools" :silly:

So yeah, I'm definitely going to call it and say any of these "massive" batteries from AliExpress to replace on your LeEco Le Max 2 are definitely fake hahaha... I should have just ordered an OEM battery. Oh well, lesson learnt the hard way.

I'll be waiting for all my parts to arrive before I open up my x2 though as I'll definitely want to fix everything at one go.

I have a question for you all. Did anyone find a way to make "sky go" work (to see sky with a regular subscription) on Lineage 17.1 ? Magisk worked for some time but about two weeks ago stopped working and the app started complaining about rooted system.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] tr0ubles0me:
The way I deal with programs that detect root despite Magisk being hidden is with a program called "Island" from the Play Store. I prefer the Magisk way, but some apps (banking, etc.) just find a way around it. What Island does is it basically enables the work profile on your phone, with it's own sandbox-ed environment. After you install and run it all you have to do is clone the problematic apps to that profile and run them from there. It's pretty self-explanatory when you tinker with Island. A shortcut of an app form your workprofile will have a small briefcase on it's icon, so you just run it from that shortcut and not the regular one.

For me it worked with Santander's banking app perfectly. An added bonus is that you can be logged in with two accounts at the same time for a single app, let's say for Facebook or whatever you need.

Let me know if that helped.

Cheers :)

Hi all,

I have been using lineage-17.1-20200511-UNOFFICIAL-x2 for two days and no issue so far.

I wanted to install it because I am interested in infra red feature in official builds.

[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo [MENTION=9060031]mastervipreturns[/MENTION] , hmm for something like that? It could also be due to your WiFi router settings? Are you using 5GHz or 2.4GHz band? You could try the other to see if the issue still continues.

Another thing you could try us to reset your router back to factory and see if the issue persists.

[MENTION=7732756]erwan574[/MENTION] glad that the latest unofficial works good for you! I still have no idea when the official build servers will be online as the hack tool them offline, but in time I'm sure they'll be fully prepared to work again. :good:
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] mastervipreturns:
ok its was 5Ghz , damn, i finally discovered why my wifi drops alot in my x829, its because, 5GH wifi i will use 2.4 and problem solved , its not greenify, its not private dns or firmware its 5ghz wifi maybe i have ****ty router too but its very weird because i used Los 16.0 for one year and i had 0 problems with 5Gh same Router
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
[MENTION=9060031]mastervipreturns[/MENTION] you could always try changing your 5GHz settings. For example, instead of automatic settings, specify WPA2 and AES. There shouldn't be a reason you need WPA1 and TKIP unless you have an original Nintendo DS or something.

I haven't had any issues with 5GHz, so my guess is it's potentially router related.

After encrypting with this ROM, TWRP can't decrypt (always says password is incorrect). Is this expected? I've installed Lineage recovery but it seems very limited (i.e. can't flash zips.)
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo [MENTION=1607904]bwalter[/MENTION] , please ensure you're in TWRP version 3.3.1-1 official as older versions aren't compatible to Android 10 ROMs.

Lineage Recovery as mentioned in the first post is recommended as the installed recovery on encrypted devices as TWRP fails to do OTA updates properly via the Lineage Updater as it doesn't set up the proper permissions for the Google Services Framework and that causes it to crash and all apps that reply on GSF to also crash. Lineage Recovery works perfectly for OTA's via the Lineage Updater.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] bwalter:
Yes, I was using TWRP 3.3.1-1 official. It installed the April 23 official version of this ROM fine. Then I encrypted. After that I can't mount/decrypt storage with TWRP. I'm rooted so I used Flashify to install Lineage recovery but I'm wondering what will happen if I ever need to do anything more advanced from recovery.

Edit: Used Flashify to install TWRP again and now it works. Nice to know I can switch back and forth. Maybe I'll just install Lineage Recovery temporarily when taking OTAs.

I'm also forcing HAL1 for Facebook, Facebook Messenger, Instagram, Viber and WhatsApp as they sometimes have issues with camera preview freezing with camera HAL3 on our devices because the camera blobs were only meant to be used on HAL1, and on HAL3 sometimes mm-camera-daemon fails to get the preview frames which causes the preview to freeze. Forcing these apps to use HAL1 prevents this issue from occurring and these apps don't require HAL3 for full functionality.
