Did you actually try:I`m on snapdragon s10 version and this method doesnt work.
My path is /dev/block/platform/soc/1d84000.ufshc/by-name/
After doing ` dd if=/sdcard/up_param.bin of=/dev/block/platform/soc/1d84000.ufshc/by-name/up_param ` i got feedback:
3215+0 records in
3215+0 records out
1646080 bytes transferred in 0.019 secs (86635789 bytes/sec)
Rebooting and i see no changes
