 +==== Installation using a modded CFE bootloader ====
 +It seems the original bootloader doesn't allow to boot OpenWrt images, see -> [[https://forum.openwrt.org/t/huawei-echolife-hg622u-corrupted-image/209175|Huawei EchoLife HG622u corrupted image]]. You will need to upgrade the CFE bootloader with a modded one before installing OpenWrt.

 +Upgrade the bootloader via TFTP using the serial console:
 +<code>
 +CFE> f 192.168.1.100:CFW_HG622-dummy_firmware.bin
 +Loading 192.168.1.100:CFE_HG622-dummy_firmware.bin ...
 +Finished loading 87360 bytes

 +Flashing CFE: ..
 +</code>
 +
 +After upgrading CFE you will have a web server at ''%%http://192.168.1.1/%%'' for uploading new firmwares. You only need to upgrade the CFE once, the bootloader will remain forever installed.

 +<WRAP center round tip 60%>
 +It's recommendable to install an old Openwrt version to avoid running out of memory. But don't install any version between 17.01.5 and 18.06.3 (both included), they likely erase the wifi caldata partition. Version 17.01.4 should run fine:

 +
 +Install OpenWrt via new CFE:
 +  - After power power cycling the device, press the reset button when powering on the router and wait some seconds
 +  - Release the reset button
 +  - Browse to  ''%%http://192.168.1.1/%%''.
 +  - Install OpenWrt binary image.
