[MENTION=8877649]bluehillday[/MENTION] , as mentioned in the first post for instructions I currently only recommend Open GApps pico and nano between April 3rd and April 8th. Newer builds have had issues and I'm guessing from your post that even open_gapps-arm64-10.0-nano-20200422 has problems too... Just to check, did you clean wipe again and reinstall with April 8th's Open GApps build?

Heyyo [MENTION=4485668]joaopalmeira09[/MENTION] , I definitely love my Le Max 2 as well so I'm glad you also get to enjoy Android 10 on it. :good:

Unfortunately, the radio antenna in all LeEco phones are actually not that good as they aren't long and the metal chassis only makes it worse... one other option is to try to use updated APN settings from Google. I made a flashable zip if you would please check my first post under misc downloads. It would be under the mods and tweaks section of my SourceForge page.

defenetely clean wiped . i have instaled this rom with aprils 8th's nano version it simply didn't want to download anything , i have clean wiped again and instal the april 3rd pico version. same bug occured here but this time it started to dld after letting it stay for 10 minutes . i think if i dld one app and wait for it to finish without queing another dld it works but if i try to dld more, then this bug arises. and even if i cancel all dld's and then try to dld a solo app the same message appears without the dld starting

edit: it works now with april 3rd version. also this is the only ROM i've tried that makes mirror cast work with my TV

Wow ! Thanks ! Thanks ! Thanks ! Thanks ! Thanks ! Thanks ! Thanks ! Thanks !

You can't imagine the time i losted with APN configuration with custom roms ...

By default, i had 50 APN, with updated APN settings I've got the only needs ;)

So why these settings are not used by default (LineageOS and others ...) ?

Your flashable zip run only with Android up to 9.

With Android 10 the file has moved from /system/etc/ to /system/system/product/etc/

I modified the path in updater-script file but I had to run it 2 times (it makes an error at the first execution but it runs fine at the second one).

I don't know if the network is more unstable now with Android 10 but with Android 9 the signal icon was full and not with Android 10.

The network speed is the same even with less signal but i don't move a lot so i can't say if the signal will be lost more faster with Android 10. It could be a problem.

I use x821 version and I flashed pseudo-firmware-466D-X821-le_x2.zip with Android 10.

last los 17.1 build 28 april, bootlooped my phone.....
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] maxrocks.90:
Same my phone is in bootloop. After few minutes, it goes to recovery
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] _arafel_:
Same here, had to install back the nightly from 04/27 from recovery, after that it booted without issue.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] SharkyGTI:
mine also - have been on 27th before... I installed image april 22nd again but device still falls back to recovery during boot :(
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] _arafel_:
This happened to me as well: I first tried flashing the image from April 22nd because I had it already on my phone. However, I downloaded the build from April 27th (i.e. the image that I had just before the botched upgrade), and it worked.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] SharkyGTI:
Yeah, I´m up and back to a working phone - 27th april is actually still working. Just wondering why 22nd april and even 25th march got me no success. Open Gapps nano is now at 28th of april and seems to work allright. The updater on my phone already wants me to update to 28th of april again but now I can withstand ;)
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] :
It is bootlooping for me too
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] _arafel_:
This makes me think... perhaps it's the image from April 27th the one that is somehow wrong and "breaks" the system for further upgrades? I hope we won't have to keep it forever! :eek: :P
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] Dudeman71:
Where are the nightly download files located to install back to 27.th??

Thanks in advance
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] _arafel_:
I'm not sure I can post links: https://download.lineageos.org/x2
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] Dudeman71:
Sorry, I ment the download path inside the Rom!!
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] _arafel_:
Ah, that I don't know... I have set them to auto-delete :D. I downloaded the image again from my PC, and then sent it to the phone (in recovery mode) through USB. ADB sideload would probably have worked as well, but I had enough space, so...
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] alqi:
Mine boot looped too after 28/04 update.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] Dudeman71:
Went back to 27.th with adb sidelooad! Booted fine into system!! Thanks for tipps
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kroppy:
Mine bootlooped too. I have downloaded previous from 27th, copied it to usb key and flashed it from twrp using USB to type c adapter.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] _arafel_:
I have just noticed that the build for the 27th has just disappeared from the download page! Is there a reason for that? Does it mean that those of us who installed it now have a somehow broken installation? :(
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, for anyone bootlooping please grab pstore from recovery.

1. Reboot to recovery after a few minutes if it doesn't automatically do so

2. adb shell cat /sys/fs/pstore/console* > pstore.txt

3. Attach pstore.txt here

I'm guessing there was some merged commits that broke builds for us, but luckily since we do have nightly builds the previous builds that are stable should be fine.

If you're using TWRP you can also use the local terminal in advanced settings and save to /sdcard/pstore.txt

[MENTION=6904104]Dudeman71[/MENTION] the path is /data/data/org.lineageos.updater or something similar to that is where the built in updater downloads to.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] _arafel_:
The build from 27th disappeared from the downloads... does it mean that those of us who are using it have something broken? Should we expect the next build to work for us, or will it more probably fail as well until we fix whatever the issue might be?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kayyappan:
It's located at /data/lineageos_updates directory. You can use the file via TWRP.

[MENTION=6235294]ThE_MarD[/MENTION] i think their is problem with 28 april build as i tried to fresh install this rom by sidedload , i was stuck in bootloop as it was after update. then i had to install again 27 build as this is my primary device and sorry i have read your comment later and i was unable to provide "pstore.txt"
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, so I finally got time to check it out and the issue was due to snap camera. They seem to have merged a change but forgot to merge the privapp permissions for it which caused snap to cause the bootloop.

E AndroidRuntime: java.lang.IllegalStateException: Signature|privileged permissions not in privapp-permissions whitelist: {org.lineageos.snap: lineage.permission.PREVENT_POWER_KEY}

I've asked the LineageOS team to take down that build. Unfortunately, it seems our build on the 28th started before that fix was merged, hence it is broken like our build on the 27th was. As always, it's good to have everything important backed up off of your x2 before doing any updates as you never know when something will break it.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] :
So 30th build should work fine, ie it has the fix merged .

So can I update to it if I am running 27th.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] :
I am on 30th build fingerprint is not working for me on it.

P.S. - Clean flash

After update to April 30, 2020 build, fingerprint sensor has stopped working. I clean flashed the build, still fingerprint sensor is unresponsive
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] Uplander:
30/04/20 update use recovery to wipe cache/dalvik to fix fingerprint sensor...Worked for me.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kailash_52:
I use TRP made by Lineage which is recommended. In this TRP, there is no delvik cache wipe. AS mentioned above, I wiped cache, data and system and then clean installed; but fingerprint problem still remains same.

Had bootloop on 28/04 build, clean flashed 27/04 and everything came back normal. Updated 30/04 build and not a problem detected, finger print working for me.

Thanks Marc for the great job done on this rom!
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] _arafel_:
Same here, I installed 28/04, then downgraded to 27/04 and now straight to 30/04 and it worked without issue so far (at least it boots and fingerprint is working so far).

*edit omg double-post bug attacks... xda forums still broken for me I guess.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] joaoVi:
i just clean installed the latest build, and my fingerprint is not working anymore either
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kailash_52:
I had updated to April 28 build after which I was in boot loop. I wiped the data but no use. I factory reset, again no result. I downloads added the April 30 build, but fingerprint stopped working. Wiping cache and data didn't change the situation. This is my only device, therefore I had no option but to go back to April 25 build. Fingerprint is working fine with April 25 build. Sorry, since I clean flashed I can not provide the information sought by you. I will try once more to update from April 25th build straight to April 30th build, I am keeping my fingers crossed.

---------- Post added at 06:23 PM ---------- Previous post was at 05:54 PM ----------

After going back to April 25th build and ensuring that fingerprint is working fine, I updated directly to April 30th build and I am happy to inform that fingerprint is working fine. As few other members have also reported, its a mystery why fingerprint do not work on clean installation of April 30th build. By all accounts, there is serious problem in April 28th build, all my problems of boot loop and subsequent non-working of fingerprint started after applying update to April 28th build. It will be better if April 28th build is immediately removed from the downloads.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kroppy:
Updated to 30th, no problems so far. My fingerprint sensor works, so I assume log won't help.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kailash_52:
On the download page, updated Lineage recovery file (.img) is also provided. I have installed Lineage recovery, but I am unable to update the recovery because there is no provision in Lineage recovery to choose .img file. How to update the Lineage recovery?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] :
Please check the screenshot ,

I am unable to enrol new fingerprints in 30th build

I have 1 fingerprint enrolled when I was on 25th build is working.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] :
That's not working for me

All the downloads after 23th build have been removed:eek:

A few questions about installing LOS 17.1.

Hi, guys,

I've got x829 bought 3 years ago. The phone came with stock software 5.9.16s which was just crying to be replaced by a custom rom. So what I did back then was the following: I flashed TWRP 3.0.2.1, modem 466d, Resurrection Remix 5.8.4 (Android 7.1.2), opengapps and magisk (versions that were latest at the end of 2017) and I've been using the phone happily ever since, occasionally updating magisk from time to time. No problems what-so-ever. I've not participated a lot in this forum for the last couple of years.

But now, due to the staying at home thing and the pandemic, I decided to come back here and see what's going on... Oh, WOW :)

Straight to the questions:

1. Having in mind my current configuration (Android 7.1.2), is the LOS 17.1 install method in the first post still valid for me.

2. What's that "treble" in the thread title?

3. How can I check if some partition on my phone is encrypted, so I know if I need to go with TWRP or Lineage Recovery? I'd like to have OTA updates if possible, but I like TWRP as much.

4. I guess dirty install is totally out of the question?

5. Is it better to go with LOS 16 instead of LOS 17.1 in terms of stability. I'm not looking for cutting edge stuff and so on, so I guess LOS 16 would have more bugs fixed and will be generally more stable.

6. Anything else I should know before I jump to the installation, or anything else I should have asked :)

I'm generally tech-savvy. Thanks :)
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] decentguy49:
In a nut shell, yes method posted in OP is still valid for you, make sure you are on latest TWRP and then make a clean flash of LOS 17.1 along with OpenGAPPS, if you want then install MAGISK as well and you are all set.

To your question of LOS 16 or LOS 17.1, i will suggest to go with latest one as it will get latest features and bug fixes more often then LOS 16.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] tr0ubles0me:
Thanks, mate. Since yesterday I've read quite a lot about that TREBLE thingy, but it's still not quite clear to me if I need to treblelize my phone before installing LOS 17.1. Are you saying that LOS will treblelize my phone? I mean, the installation will create vendor partition, install GSI and so on? Does anyone know which GSI is LOS using?

Thanks.

[MENTION=6235294]ThE_MarD[/MENTION] i have this rom but eversince i have updated the firmware from stock to 466d (le max x820) , charging is not working anymore, or works very very slow. it doesn't recognize quick charge, and a message appears at the bottom when i plug charger ''charging slowly'' i have bought another charger but it was pointless. can this ROM work with other firmware?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, a new and VERY exciting test build is going up! Link as always in the first post. lineage-17.1-20200502-UNOFFICIAL-x2 contains an open-source ConsumerIR HAL + bridge implementation that is both selinux enforcing and selinux neverallow compatible with special thanks to meaning (not sure if he's on XDA but he is on Telegram) for working on this with me! Which means we are almost ready to merge this on OFFICIAL builds! Then anyone can enjoy IR with MiRemote or Zaza Remote (Zaza Remote only works with selinux enforcing, otherwise it'll try to write to /dev/ttyHSL1 which is the device port that our IR uses and it causes the IR to not work). :good:

This build also of course contains the VNDK current commits as well. ;)

[MENTION=7443972]joaoVi[/MENTION] as mentioned before, please submit logcat so we can try and figure out what's going on.

[MENTION=10654447]kailash_52[/MENTION] in the developer options there is a setting to update Lineage Recovery with ROM updates. Please enable that and it'' automatically update it for you. :good:

[MENTION=8125493]tr0ubles0me[/MENTION] glad to see you decided to check out the XDA forums for x2! Yes there's been plenty of developments for x2 since nougat hehe. I've done a lot of work to clean up the device and vendor trees for us as there was a lot of random errors and uneeded entries.

Treble means project treble, which was designed to separate the system (Google's) changes to Android from the OEMs (vendor). The main benefit of this is the ability to be able to flash Generic System Images (GSI's) so that we can try other ROMs without the need of someone specifically building a port to that ROM. With the developments of VNDK current? That should also mean we can boot GSI's with selinux enforcing as well which is nice. :)

To check if your phone is encrypted? You can go into Settings > Security > Encryption.

Dirty install is definitely out of the question as you are coming from another ROM. You MUST do a clean wipe and flash.

It's up to you which way you want to go, but LineageOS 17.1 does have a lot of fixes that I'm not going to port back to 16.0 as that would be a heck of a lot of work to do for an older version of Android that won't get newer official builds as our official build is only for LineageOS 17.1.

[MENTION=8877649]bluehillday[/MENTION] you can use other firmware if you want. I only recommend 466d for LineageOS 17.1 as it has updated installer scripts for Android 10 ROM support. Device firmware shouldn't affect charging speeds tbh. For sure have you tried both a new charging block and USB cable? I also recommend verifying charge speeds via AccuBattery app as the lockscreen is terribly inaccurate.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] tr0ubles0me:
Will unofficial builds update OTA to the future unofficial builds?

So, as far as I can understand, the install process of LOS 17.1 will treblelize my phone, although I don't have a vendor partition at the moment?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] decentguy49:
Yes LOS will make vendor partition and all for you, just install latest TWRP and latest LOS and you will be ready to go.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] bluehillday:
[MENTION=6235294]ThE_MarD[/MENTION] yes i have changed the charger. it charges extremely slowly like 10-12% in 8 hours. and that's because quick charge doesn't kick in,and i have the app you mentioned, it shows the current mA status. i have to unplug and plug several times untill quick charge kicks in. can i flash the firmware over the current 466d? also where can i see the firmware ? in the ''about phone'' it isn't showing anymore like it used to appear in the stock eui rom
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
[MENTION=8125493]tr0ubles0me[/MENTION] there is no automated OTA for unofficial builds. They must all be manually downloaded and flashed. You can switch between unofficial and official builds easily though and official builds do have OTA via the Lineage Updater.

LineageOS automatically sets up treble on x2 and zl1. How it works is there's an unused and unformatted partition called last_parti on our devices and we initialize it and rename it to vendor. This doesn't affect going back to stock EUI ROM as EUI ROM never uses that partition. Once your vendor partition is set up it will stay that way unless you ever QFIL which resets the whole partition table anyways.

[MENTION=8877649]bluehillday[/MENTION] hmm that doesn't sound promising, usually for slow charging being stuck there it is faulty hardware, so if changing the charging cable and charging block doesn't fix it? There is a chance it could be something up with your x2... There isn't a way to tell which firmware is on your x2 as LeEco never did setup timestamps on our modem firmware, but yes you can flash over existing firmware without issues.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kailash_52:
I am facing exactly the same problem after updating to Unofficial 2nd May update. Till on April 3oth update, the quick charging was working perfectly fine.

The developers are putting their best efforts to bring improvements and new features in to the builds and I appreciate their efforts and hard work. That said, I personally feel that in last 10 days, the updates seems to have been released without adequate testing since every Official and Unofficial builds after April 23rd have problems. Of course, all official builds after 23rd April have been withdrawn.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] bluehillday:
[MENTION=6235294]ThE_MarD[/MENTION] well.. after i plug it and replug it several times it works, and a message at the bottom appepars like ''charging and estimate time left untill full charge'' whereas if it's not quickcharging it says only ''slowly charging'' . if it is a hardware problem shouldn it not work 100% of the times? it works after several replugings
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kroppy:
[MENTION=8877649]bluehillday[/MENTION] I had similar issue, changed cable, helped a little, but not 100%, i had to plug and unplug several times to make it charge rapidly. In my case it was lint in the port! I took a needle and pulled all that dust and lint from it, now it charges immediately. I'm not saying it may be your case, but worth a try.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, a new test build is going up! It will be done upload within 10 minutes of this post. Link as always in the first post. lineage-17.1-20200504-UNOFFICIAL-x2 contains the same updates to the open source consumerir HAL + bridge and VNDK current but also features a fix for miracast as it was reported broken in the last build so now it will work with VNDK current. :good:

[MENTION=10654447]kailash_52[/MENTION] , thank you for the kind words. The issue with the official builds though was the build servers were having issues doing repo syncs before building, so it wasn't including all merged commits before the builds were made, which resulted in some broken builds. :(

For my unofficial builds though, I have not done a repo sync in a while so that is unaffected. The point as well for my unofficial test builds is to of course test changes that I've made before merging them into official builds... so yeah, sometimes there will be bugs, but that's the exact point to having the unofficial TEST builds. :silly:

[MENTION=8840628]kroppy[/MENTION] that is a good suggestion! Thanks for the input bud. :)

Will this Rom work on x900? It ususes snap 810 instead of 820, it seems that rest is the same. Tell me at least if it is safe to try? Or it will for sure hardbrick my phone.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo [MENTION=2529763]unfire[/MENTION], this will NOT work with x900 because it is Snapdragon 810. The LeEco Le Max with SD810 is on kernel version 3.10 and we are SD820 which is on kernel version 3.18. We also do not contain any of the kernel source code that the Le Max requires, so it would be a guaranteed brick if you even somehow managed to flash it.

I would check if there was any advancement made for x900 custom ROMs. I have zero plans with it since I don't even own one sorry.
