[LeEco Le Max 2 Guides, News, & Discussion] YuriRM:
We need to get a database for LeEco Le Max2 because the components and drivers for the several revisions of this device may differ. Under-the-hood disparities may affect the behavior of ROMs.

A nice hardware diagnostics tool is the Device Info HW app by Andrey Efremov. Therefore, I request that you install the app and select Upload device information at the Info Center option in order to feed the Device Info HW database by Andrey Efremov. Then check the database for comparison with other LeEco Le Max2 devices.

Links and detailed instructions at the end of this post.

133 devices are registered already at the Device Info HW database for LeEco (Le X820, Le X821, Le X822, Le X823 and Le X829).

117 devices are registered as MODEL

Le X820

or LEX820.

However, some masked X829 are registered as X820. Why does that happen? These devices are in the X820 database because their build.prop file has been modified by a custom ROM. A second opinion is that masked devices are firmware related and not ROM (build.prop) related, that modification happens when a Chinese/Indian modem is flashed on the american model (X829). Do custom ROMs allow deeper component testing than stock ROMs? Sometimes they do, depending on SoC, manufacturer and developer choices. Report to this thread when the tests performed by the Device Info HW app (or AIDA64 app) provide positive results on CAMERA drivers or other missing data shown below. Give us details of your device model and ROMs, please.

Feedback is welcome from owners of X829, X823, X822, X821 and X820.

Only 17 devices show CAMERA results. Why is that? Let us know who you are! Give us details of your device model and ROMs, please. Is the Device Info HW app able to detect your camera drivers? Let me know if your CAMERA drivers are not listed here too! Do not forget to provide screenshots.

Update: CAMERA has positive results on these ROMs:

Missing data - LENS, PMIC, RTC, WIFI, MODEM, FLASH, NFC

The creator of Device Info HW gives the following explanation for missing data.

"New devices with Universal Flash Storage (UFS) memory chips use the name 'SCSI' instead of 'FLASH'.

PMIC and RTC are integrated in SoC.

WIFI on Qualcomm is shown if an external chip like bcm4xxx exists. For others I found correct info only for some Xiaomi devices.

MODEM - on MediaTek it contains the project name, for others only the baseband is available.

NFC - it seems that it isn't supported.

LENS - I can't find for this device, may be when the Phase Detection AutoFocus (PDAF) actuator library is not used.

On some models the enabled driver for fingerprint sensor is: goodix_fp."

The developers of custom ROMs for LeEco Le Max 2 must include all these drivers!

Update - I think that there is a need to know the original drivers 'out of the box' in all LeEco Le Max 2 (X829, X823, X822, X821 and X820). Let me know if you have the original ROM and provide screenshots of the test, please.

Everybody should install the Device Info HW app by Andrey Efremov in order to register the components and drivers of their devices in the database. This is a great help for developers and will ensure that your device is supported too!

Install the app, give it the permissions that it asks for (INTERNET, CAMERA and ACCESS_WIFI_STATE ), and manually select "Use Root" at the Settings option. After applying root you need to restart the app. Then select Upload device information at the Info Center option in order to feed the Device Info HW database. Finally check the database for comparison with other LeEco Le Max2 devices.

NOTE - Thanks to [MENTION=7914507]Palm Trees[/MENTION] for his suggestion of a better format with improved readability for this list and also the creation of a dedicated thread! Thanks to [MENTION=2934546]TioCareca[/MENTION] for his suggestion of a test on stock ROMs and also for the title of this tread. Thanks to everybody who provided feedback and screenshots.

NOTE 2 - Our conversation will no longer flood the EUI 6 and AICP threads. You may consult previous posts there (test results and screenshots).

Thanks to [MENTION=6760768]KuranKaname[/MENTION] and [MENTION=1187148]infrag[/MENTION] for their kindness and tolerance.
