Anminer s3 bricked after firmware upgrade.....
a firmware upgrade was performed on my s3 and now it seems to be bricked. no way to login to it in current state. not really sure what protocol seems to be at this point
i have contacted Bitmain several times (on bitcointalk, the bitmain site, and via RMA email) about this issue with no response.
aside from using it as a paperweight, anyone have suggestions on how to fix or get it going once again...is this s3 bricked state even fixable ?
thanks in advance for all input and help.
Hi,
I have the same problem before a Firmware upgrade, so, i decide open the BOX.
The Antminer S3 use a AR9331 Module, this module is like a any other router that is compatible with OpenWRT.

Loking the board and the pinout of AR931 i descover this:

With that proceeded to identify which was the TX and RX serial port in the plane is said to TX and RX pin 16 Pin 17
I had to soldering on the pin board on March 1 order then would wire the port and not soldered to the board directly.
Use yellow for RX, TX to Red and Black to GND, as shown in the following image:

screen /dev/ttyACM0 115200
Where /dev/ttyACM0 is the serial port that is created to connect the arduino board to pc.
https://dl.dropboxusercontent.com/u/2113596/HackingMinero.pngWhen connecting either achieved was only a matter of time to achieve putting on good firmware to do this is as follows:
1 It is necessary that your computer has the IP 192.168.1.100
2. install and configure a tftp server on which team has the firware, I use the version: antMiner_S320140811.bin
After having the TFTP server on your computer and have the computer connected by serial Mining and the lan port only has to ejectuar the following commands:
tftp 0x81000000 antMiner_S320140811.bin
cp.b 0x81000000 0x7c0000 0x9f020000
bootm 0x9f020000
Longer then promise you to to make a better guide.
Happy mining.
