Can update from Lineage 16 Pie, or need to clean flash?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo [MENTION=6607081]kanagawaben[/MENTION] , currently upgrading from LineageOS 16.0 isn't supported, so I would recommend a clean wipe with dalvik, cache, data, system and vendor and then flash LineageOS 17.0 and gapps. You can try upgrading from LineageOS 16.0 but tbh I don't think it would go well.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kanagawaben:
That's what I figured. I will leave it on 16 for now as it's my daughter's phone just now and I don't want to mess with her apps and data. However, I have a new phone on the way for her (Umidigi X) so will reclaim the old beast from her when that arrives and clean flash 17 then. Great work btw.

Is f2fs implemented? Already try to flash 3x with no success. After a clean install (/system, /Vendor, /Data, /cache & /dalvik already wiped) I can see only the lineage animation for hours. My /data (internal media also) , /Cache are f2fs formatted.

What I already try:

Los17 + nano gaps from OP

LOS 17 alone

LOS 17 + BS Kernel

now I am back...thanks God I made a twrp backup..to los16 (f2fs) + bs

Edit:! I think it doesn't boot with los17 because my los16 (including interna SD) is encrypted! I ll try again later and post the results here! first need to completely backup the internal sd to my pc

[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] erwan574:
I used lineage-17.0-20191119-UNOFFICIAL-x2 almost for one day with no clear issues. I feel some lags but this may comes from my apps.

The kernel version is still 3.18.x which reached end of life at the beginning of 2017. So maybe we have to live with known vulnerabilities.

Speaking of boot animation :

Trying to play safe I cleared Cache/Dalvik/System/Vendor and flashed the new image forgetting to re flash the gapps. This also brings lineage boot animation for ages (not infinite after a while it goes back to recovery). Reflashing with gapps and magisk made the phone boot quickly
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kayyappan:
There may not have been any problem with 11/17 build. I faced the same issue even with 11/19 build just prior to posting this. Here is the list of what I did:

1. Took a backup of boot, cache, data, vendor and system, as I normally do, so that I am back precisely where I was at the beginning without any issue.

2. Wiped all including data.

3. Tried a GSI with P boot and vendor of another ROM

4. Wiped all to return to LOS.

5. Transferred the backup from PC to phone while in recovery.

6. Restore - Reboot and ended up with loop - after booting but during "Phone is starting" info on display the device will start again with boot animation going thru the same loop.

I might have tried a GSI on 11/17 after LOS install over 11/16 build too though I do not remember now.

Today after facing the same issue, I wiped all, transferred only boot.emmc.win, renamed as boot.img then installed on boot. Rebooted to recovery, transferred my LOS 17.0 (11/19 build) backup, restored all except boot and I am back where I was.

But what puzzles me is why the restore of boot.emmc.win of LOS 17.0 did not do what I did manually. Something in TWRP? It may be as only boot is left out of all wipe. TWRP 3.1.1-0.

This reminds me of https://xdaforums.com/showpost.php?p=79500048&postcount=752 but here SELinux is anyway permissive!
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo monleylord, oh you're right I haven't tested encrypted yet sorry so it might not be functional. f2fs afaik should be implemented since it's still in the kernel.

Yeah that is a LineageOS ROM bug, so I'm sure they'll fix it before official 17.0 builds start. No idea if we will be ready this time though for initial devices since snap camera app not working is a pretty big issue for us...

Glad to hear it worked fine for you :good:

I'm unsure if I can even solve the USB issues with kernel 4.4 that infrag started to work on... I'll try I guess once I'm done with LineageOS 17.0 bring up but no guarantees...

Oh Hmm, maybe it's device firmware related? You can always try to reflash your device firmware and see if that helps?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kayyappan:
I tried that on 17th itself. Used 30s as given in OP. No luck. I've 19s full & 30s on PC for any eventuality.

I can reconfirm tomorrow.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] kayyappan:
Today I opted to try as per the following:

1. Take backup of LOS 17.0 build 11/19 - boot, cache, data, system and vendor.

2. Copy TWRP folder to /home/kay/LOS

3. Format data, wipe all including internal storage

4. Copy BaikalOS(Pie) boot.img, vendor.img and any working GSI to X2 internal.

5. Install boot, vendor and system img files, reboot.

6. Upon successful boot of the GSI, reboot to recovery.

7. Format data, wipe all including internal storage.

8. Reboot to recovery

9. Copy LOS 17.0 backup taken as per step 1 to device internal.

10. Restore boot, cache, data, system and vendor. Reboot upon restore completion.

11. In case of loop, reboot to recovery, install newly downloaded 30s system FW.

12. Reboot.

It worked OK on reboot on step 10. No need to restore boot first, reboot to recovery to restore rest or install system FW as mentioned by me earlier. But now I am lost :o:confused: - I am not even anywhere near end of read/write cycle lifetime of my X2 to suspect mem failing...:D.

Feedback!

It was the encryption! Now I am on Los17!

For other that maybe face the same problem as I (encryption +f2fs in pie) and cannot upgrade to Android Q. First ensure that you have a full TiBu and a twrp backup! After this go in recovery and copy/backup the whole /internal Sd to your USB stick or PC. Then you must downgrade your recovery prior to twrp 3.1.xx to get rid of the encryption in f2fs. After this you can go up again to the latest recovery and flash Los17+gapps.

Last but not least, you can now restore everything from your previous made TiBu/Twrp backup!

Heyyo, build lineage-17.0-20191121-UNOFFICIAL-x2 is up! This build has snap camera app fixes so it works again lol yay... you may need to go into app info, force close it and clear storage on that app and then it should fully function. I also started checking out the sepolicy fixes but it's not enforcing yet, but I'm surprised at how little we need to adjust device-wise anyways. :good:

[MENTION=3782246]kayyappan[/MENTION], hmm that is super odd... there could just be something messed with your device partitions? You could attempt QFIL if it keeps acting up so weird and then format data and wipe dalvik, cache and system and then flash device firmware of choice and then flash LOS 17.0 and gapps and reboot to system

[MENTION=6950590]monleylord[/MENTION], glad to hear you got her up and running! Yeah, I'm not sure when encryption will be fixed for us. Upgrading from LOS 16.0 to LOS 17.0 isn't supported yet either, so for meow clean wipe and flash of LOS 17.0 is required

Heyyo [MENTION=3514001]xyomguix[/MENTION], cool! your logcat looks clean of any selinux denials so you're 100% good to go. :good:

[MENTION=5857902]maxrocks.90[/MENTION], hmm there's still something going on with your data, so, unfortunately, I'm going to recommend formatting your device and then installing from a clean slate.

Please backup everything important off of your x2 onto an external storage like a PC or a USB OTG device

Use Lineage Recovery (you can just temporarily boot to it via "fastboot boot lineage-17.1-recovery-x2-20200420-UNOFFICIAL.img" if you want to keep TWRP as your installed recovery)

Go into "Factory Reset" and select "wipe data/factory reset"

Go into "Factory Reset" and select "wipe cache partition"

Go into "Factory Reset" and select "Wipe system partition"

select "Apply update" and "Apply from ADB" or if you have a USB OTG device with the latest test ROM please use that instead"

If you're using adb sideload? Please use the command "adb sideload lineage-17.1-20200420-UNOFFICIAL-x2.zip"

If you want to optionally flash OpenGapps, please use an OpenGapps arm64 build between the dates of April 3rd, 2020 to April 8th, 2020 as newer ones might be unstable.

Reboot to system now and then test the fingerprint sensor out.

I got the same problem with the same build and 8 april gapps.

It doesn't want to register my fingerprint. It says lift your finger and touch the sensor again. But I already did that. Maybe its just faulty scanner idk:
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] :
I know what is happening on your case, this problem occurred to my device earlier , the fingerprint just gets vibrated/imprinted once and then stops working you can solve it by

Go back to any eui based ROM and then in setting's search for fingerprint calibration this problem will be solved.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] Abdel1998:

Heyyo [MENTION=5857902]maxrocks.90[/MENTION], hmm in logcat it keeps spamming this, that it's waiting on the Qualcomm Fingerprint Service (more specifically, vendor/app/QFingerprintService/QFingerprintService.apk) and eventually it just decides to close the biometrics HAL...

I ServiceManager: Waiting for service 'android.apps.IQfpService' on '/dev/binder'...

One thing to try is to backup everything important off of your x2 and wipe all partitions and format data and then flash EUI ROM (you'll probably need an older version of TWRP like 3.1.0-0).

If that doesn't work? I would recommend QFIL. This is the guide I followed for my x2 when I bricked it trying to use keymaster firmware from the OnePlus 3 pie release... needless to say? not a good idea to try to flash firmware from a different device lol. :silly:

https://xdaforums.com/le-max-2/how-to/guide-hard-brick-fix-qualcomm-hs-usb-t3492949

[MENTION=3459245]alancai[/MENTION], Lineage Recovery is touch enabled, but you can optionally use the volume and power buttons to navigate. If you're not encrypted you can use "install from local storage" option instead of just adb sideload. Like I've said before, the main reason that we switched to Lineage Recovery as the officially recommended recovery for LineageOS is that TWRP fails to perform OTA when encrypted which breaks Google Services Framework. If you're not planning to use encryption? Then TWRP installed as your recovery is fine which is why I still maintain TWRP for x2.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] alancai:
too bad. already encrypted and lineage recovery installed. can't go back or update anymore. :P

[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] :

[/COLOR]

I had this problem for a long time few months back and the only solution I was able to find were

1. Calibrate fingerprint sensor by settings app in Eui based ROM. ( recommended )

2. QFIL your device. (Lengthy procedure)

You may check this post of mine even one another user had the same problem and was able to fix it by my procedure.

[MENTION=5857902]maxrocks.90[/MENTION], unfortunately it does sound like with everything you tried that it is a hardware failure. :(

You can always buy a new fingerprint sensor and try to replace it yourself or have a repair shop do it if you really need a working one again.

Heyyo [MENTION=4520958]origin_de[/MENTION], have you also had that issue in LineageOS 16.0? Nothing with volume levels have been touched, so it should be the same from 16.0 to 17.1?

Otherwise? you could try to modify your /vendor/etc/mixer_paths_tasha.xml but you would need to know what is the volume source for that mixer path and increase the volume for it manually, same for the microphone.

Heyyo [MENTION=7193614]Uplander[/MENTION], I'm glad you're enjoying LineageOS on your x2! :) Definitely the upgrades to capricorn's nougat fingerprint blobs have been a boon for our x2. Unfortuately their oreo fingerprint blobs didn't work out for us as it constantly thinks it's registering a fingerprint.

[MENTION=9060031]mastervipreturns[/MENTION], ultimately it is up to you. I recommend the firmware-pseudo-466D-X829-le_x2 as that is what I use on my x829 but 30s would be fine as well.

[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo [MENTION=9060031]mastervipreturns[/MENTION] , that one I have no idea tbh lol.. I checked my Samsung Galaxy Tab A 8" (2018) running stock Samsung's One UI and it can install the AliExpress app from the Play store.

I did try using apkpure app and download and installed the AliExpress app and it works fine and signing in also worked... So my guess is they have some kind of weird compatibility block? Maybe it's unlocked bootloaders?

So an update on the side as I always want to be transparent with my fellow LeEco community members is that I put my name in for assisting with ginkgo (Redmi Note 8) development as they don't have any official builds of LineageOS and need help with there quad-camera setup and the trinket dev team have said they're working on sending me one. I'm unsure if it'll be my daily driver since it won't have the LTE bands that I would need here in Canada (4, 7, 12 and 17) so that means I would be limited to 3G, so I will probably just have it as a developer device... it will probably also be a month or two for shipping from Europe, so it won't be here anytime soon lol. :silly:

I definitely plan on continuing work on my x2 as I've already put so much work into it plus of course, the donations I received to help me order replacement parts (that are still in shipping and I'm hoping only half a month to a month left in shipping). I'm not sure yet what will be my next big project for it as tbh I've mainly hit a skill level issue with software development at this point as working on a 4.4 kernel and also trying to find a proper solution to our open-source ConsumerIR HAL + Bridge so that it complies with selinux neverallow policy are really difficult things to try and achieve... I might have better luck trying to figure out how to fix the 3.5mm jack for max_plus users, so I might attempt that instead???

Plus, there's still trying to find a proper fix for the echo-reference for s2 that has been a nightmare... :(

Still also no idea about nash and if I'll even be receiving one that needs to be fixed... So that's also in limbo.

I did decide to also pick up my good ol' HTC One m7 and I was having some problems, but luckily a seasoned HTC M8 maintainer for AICP by the name of claymore1297 got an m7 for cheap and brought a lot of his fixes from M8 to m7 and we do have AICP 15.0 booting, but there are lots of issues still like 5GHz WiFi doesn't stay connected, no in or out audio during calls, no mobile data and camera might still be broken and Bluetooth also needs to be fixed.
