Why? Because there is a big solder blog on them! :cyclops:
NAND flash doesn't use a lot of pins, maybe about 20 out of 48.
Pin 6 is no connection, pin 7 is Ready/!Busy.
The short is not pretty but it's not a cause of your problem either.
Your NAND flash is partitioned and you are probably only looking at one partition.

Hello community.
Anyone working on the unbrick this device?
The other day I went up a picture where you can see a semiconductor, which would block the entry into the bootloader with Fast-Boot Cable

Just the Standard USB Circuitry...

That chip is probably not anything as nefarious as you're speculating... I believe it's just the standard USB EMI filter and line termination circuitry, similar to the STF202 device. Here's its spec sheet:

FYI...

USB-OTG is working on Galaxy A5FU with CM13+AICP11

Its just for Info.
But does anyone tested USB-OTG support on A5FU?
No? Than its time to use CM13 or AICP11, because it works perfect, even in recovery to use it for backups etc, tested by me some minutes ago.
Just plug the usb stick,card reader,external drive and format like what u see in popup,done.
PICS FROM MY A5FU.

Ultraslow file-transfer speeds with Galaxy S5

Hi,
recently my S5 started to act strange: everytime I try to copy files from or to the phone it's doing it ridicules slow. Right now I'm at about 0,3MB/sec.
Another thing that happens is that while a file is copied, it shows >2GB big until it's completely saved on the harddisk:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Is there a known bug in the S5 that would explain those utterly slow transfer-speeds? Perhaps because the phonememory is almost completely used? I'm pondering to wipe it
and install Cyanogenmod, though for that I would first need to copy everything, which actually would take days....
Btw.: USB3.0 doesn't makes a difference, I would say it's even slower than 0,3MB/sec with a USB3.0 cable and MTP set to USB3.
Any help?

That's awesome, man! You took it apart and took out the motherboard, and you want to fix it.
Hope it works
