First of all, the whole A9LH process has been perfect and now I can cold boot into sysNAND 10.7 and install all cias stuff there. I am using AuReiNAND to boot up the system. I have unlinked system before I did A9LH stuff. I am also keeping the EmuNAND and having flashed it with my 9.2 sysNAND backup, i.e. the backup I did before flashing A9LH. In order words, basically I have reversed my previous EmuNAND 10.7 and SysNAND 9.2. Now it is SysNAND 10.7 and EmuNAND 9.2. I know it may be meaningless to keep EmuNAND 9.2. I just keep it maybe one day I could use it to access my HBL....or doing other stuff if necessary (not sure at this moment), or maybe I could upgrade it at a later time. Whilst everything is now perfect, it comes to my notice that I cant access HBL in both systems, neither at sysNAND 10.7 nor EmuNAND 9.2...I checked that I have firmware 9.0 from AuReiNAND in my SD card at the appropriate place. I also placed one firmware.bin (as the one from AuRei for NTR) in my SD card. But nothing changed. The result is simply that I can scan the QR code of yellow8 in EmuNAND 9.2. I can see the ninjhax debug screens with several colours screen flashing a few time, and at last I always saw a red bottom screen and then blackscreen forever...I simply cant go into HBL, just like the way it stuck in my Sys 10.7. Any suggestion and help would be much appreciated.
