Just so nobody else finds this thread lacking info or progress updates (times etc) and needs any help in this same situation.
I have finally sorted my 4tb LS-WTGL that was in Emergency mode. After hours of waiting for the updater/Nas to finish updating i decided to try different methods. AND finally i had some success.
JUST SO YOU KNOW THIS WAY I HAD TO SACRAFICE MY DATA BUT AT LEAST I NOW HAVE A WORKING NAS, WHEN STUCK IN EM MODE I HAD NONE!!!!Download the file previously posted by davo (Thanks again)
Once downloaded and extracted, open LSUpdater config file (.ini) in notepad.
This is a exact copy of my settings that worked perfect for me, copy and paste them or edit the ini as needed.
[Application]
Title = BUFFALO LS-WTGL/R1-V3 Updater Ver.3.09
WaitReboot = 999
WaitFormat = 500
[Target]
ProductID = 0x00003004
Name = LS-WTGL/R1-V3
[Flags]
VersionCheck = 0
NoFormatting = 0
[SpecialFlags]
Debug=1
Now run the LSUpdater.exe, right click on top window bar the and select debug options.
These are my settings:
Now Update, it took my 4tb Nas, around 15 mins to complete update and then shut down. After turning back on around 7-10 mins of the Amber "!" light. Once the power led has stopped flashing your Nas should be shown in navigator as ok now.
Right click go to setting that should open up your Nas control panel. (mine was reset after my update back to japanese).
Login with:
User: admin
Pass: password
Change the language to yours and enjoy setting up your NAS again.
I hope this helps someone because i spent too long trying to figure this out on my device.
