Thanks, I was thinking of trying a different USB drive. That’s very kind of you, but I live abroad. I will get it cheaper at store than the shipping costs 
Hi Jason,
Any update regarding optimization of GoControl app.
Hi Sanath,
Currently it is under test, waiting for the completion of the test will be released together with the next version of the firmware, meet us 
Oh that’s great. Will wait for the announcement
Has anyone had success changed USB format on Mac iOS? I can format to FAT16 on one of my spare flash drives, but still can’t get Amp to identify it
For anybody else struggling to get the update to work without a Windows PC, I had success from a Linux PC, by
- creating a 100MB FAT(32) partition on the USB drive, leaving the rest empty
- reformatting it as FAT 12 with
mkfs.fat -F 12 -v /dev/sdX1
and then copying there the .MVA file
@Gatorcosta it may be possible to do something similar from MacOS command line, but I haven’t tried.
In this situation anyway I think it would be best if Arylic could publish a disk image that people can write using BalenaEtcher or similar, without depending on Windows for creating a working USB drive.

UPDATED: due to the way the forum handles text it wasn’t properly showing some parts of the commands - fixed now…
By default Apple Disk Utility wants to partition all storage with a GUID partition map. It is possible that while you have a valid FAT/FAT16 partition on your USB stick the B50 does not see it because it can’t read the GUID map.
The only way I know how to fix this is via the terminal - the commands you enter are in bold:
!!! Remove ALL external storage except the USB stick you want to use or you might end up erasing something you don’t want to !!!
diskutil list external
This will display a list of attached external drives - there should be only one if you followed the advice above
Make a note of /dev/disk# for your USB stick
diskutil partitionDisk /dev/disk# MBR “MS-DOS FAT16” [name] 0
Replace the hash# in the above command with your device number from earlier and replace [name] with any 8 character or less all caps name eg ARYLIC for example:
diskutil partitionDisk /dev/disk4 MBR “MS-DOS FAT16” ARYLIC 0
This should result in a blank FAT16 partition on an MBR partition map
Copy your firmware file as per instruction and try again
Good luck…
Is there any chance to downgrade firmware? Could you share file with previous version?
I updated the device hoping for better ARC and Samsung TV cooperation, but after the update, TV cannot recognise my Arylic B50. I’m forced to use Bluetooth connection.
Hello,
I recently bought a B50 and have been attempting to upgrade the firmware from 48-b0ab8739-7 to 52-452f344c. I followed all the instructions, made a FAT (not FAT32) partition in Windows, and plugged my usb drive into the back of the B50. On the app, I am prompted to update, but when I tap “update,” the app freezes and either the lights on the B50 turn on and off quickly or they stay on for several minutes. Either way, the firmware is not shown as upgraded in the app. I’ve tried upgrading the firmware with multiple USB drives and multiple phones. I am also using the latest version of the app. Do you have any suggestions? Thank you!
Hey Ben,
as I already proposed to Slawomir a few lines above, I could send you my Intenso 1GB USB drive with wich the firmware upgrade worked just fine. Email me your adress and I’ll send it to you if you like…
Hello,
I can’t make the update of the firmware. I get the promt for the update in the app, I clik confirm, all the light just for a fraction of a second and then nothing happens. Ans so on… promt in the app…all tha same every time.
my update brick the b50 , the lights was turned on always, and after manually reboot, it’s not turn on , it’s alwasy on standby.
nothing to do for me.
why ?
Hello, I followed the instructions and had no problem at all.
Would it be possible for usb to read folders instead of
files, this will make search easier.
Regards
Hey Christiano,
Did you find a solution?
I was unable to upgrade my B50. It just gets stuck with all the lights on.
I managed to upgrade my (new) B50 using a plastic SD card reader. It’s a Chinese product using a chipset that is not well-supported otherwise.
I am getting regular drop-outs on ARC. (B50 ARC Issues with 52-452f344c - #3 by neik)
When playing from USB the song list in the app is empty.
I had the same problem too. I found in a drawer an old USB stick, a TRANSCEND with a capacity of 512 MB ! ! formatted in FAT16 and the miracle happened. This particular USB stick is more than 20 years old…I strongly suggest to find an old USB stick with a less than 2 GB capacity, format it in FAT16 and give it a try.
I didn’t get any prompt for updates.
Try it many many times.
The current version cannot save custom eq!!
Happening to everyone on B50 and BP50 as I own both. They need to update again! I know it’s sucks but we need the ARC feature!

Hello, I have a MACOS PC and the pen drive formatted in fat32, but no pen drive works, how can I fix it? I couldn’t format in FAT16. Are there other method for install the new firmware? Thank you.
