Found my old Wetek Play 2 recently and thought to give it another go. Want to use it to stream some security cams to it. Happy to see it's still supported I directly installed the latest LiberElec directly to the EMM with the EMM tool. Great units boots trying to setup Kodi finding that my CCTV plugin (Surveillance Camera [URL:https://kodi.wiki/view/Add-on:Surveillance_Cameras]) is not supported by the latest version of Kodi and I need to downgrade. No worries I found the legacy stable on the download page but than realised I am not able to select to boot from SD CARD anymore. I tried all "unbricking" methods but LibreElec won all battles and still is booting bravely every attempt I made (Tried several unbricking methods using the reset button on the bottom of the device as found in the Unbrick resources of Libre Elec [URL:https://libreelec.dtech.hu/misc/wetek-unbrick-resources/] I found a threat mentioning using DD [URL:https://forum.libreelec.tv/thread/27380-wetek-play-2-storage-resize-failed/?postID=182588#post182588]to write an image back to the EMM (as the EMM tool does not allow this as you boot from it and not having another boot option it's unusable) but that seems impossible to do so to the medium which I booted from, is mounted and I am running the OS on. Can anyone help me out here, what am I missing ? Goals is to get the 9.0 version running either on SD or EMM I actually do not care but currently I feel out of options to access the EMM / downgrade the unit. It only wants to boot LibreElec 11 whatever I try. Would be fun if I am able to fix this, I just opened the box but that also seems not to give any extra options.

Just flash the normal "LibreELEC*wetek-play2.img.gz" board file to an SD card and boot. Yes it technically still boots from emmc, but once u-boot on emmc finds extlinux.conf on the SD card and boots KERNEL/SYSTEM from the SD card, emmc is not actively used. Or at least the OS will not fault/lock-up when you overwrite emmc with the factory image. You can also do "dd if=/dev/zero of=/dev/mmcblk1 bs=1m count=100" and erase the first 100MB of emmc which will trash u-boot and partition data. This will cause the box to lock up at some point, but on the next power cycle the box cannot boot from emmc and finds u-boot on SD card, then you copy the backup file over and write the file as mentioned before. This is technically better (emmc is definitely not being used in any way) but I never had issues with the first method.. so /shrug

Just boot from the SD card. The OS runs in RAM so while there is a difference in I/O speeds, it's not that significant.
