Topic: [GUIDE] Taugeran's Antminer S1/S3 revival story guide (Read 8330 times)
I wish the reset button just worked....
Good morning I apologize for my bad English I am from Venezuela ,
See if you can help me I'm trying to follow your tutorial To A S3 to stop working after a round of light (very common in my country ) I did attempt BY putty and yes the stalls in
" [ 2.890000 ] Kernel panic - not syncing : VFS : Unable to mount root fs on unknown -block ( 0,0) "
I can not get to the other commands to not resuscitate if something is doing wrong, I 'm trying to revive from windows 7 ...
Thank you

ok I'm on putty with the serial-USB and I'm getting a green flashing light but which IP do I enter and other info on putty to connect and reset the firmware on my s3+??
bitmain told me to do this
Connect a TTL cable like this http://www.adafruit.com/product/954 to the 3 pin TTL header on the control card.
Reboot it and press "p" right away to get the uboot command line.
Connect a computer and run a TFTP server with the latest firmware on it from 192.168.1.100
Run these 4 commands to flash the firmware:
tftpboot 0x80000000 antMiner_S320150109.bin
erase 0x9f020000 +0x7c0000
cp.b 0x80000000 0x9f020000 0x7c0000
reset
I have a COM3 window open but no response after the first line (changed the baud rate and parameters of the serial connection), if it's flashing green does that mean I have the right tx, rx connection?
I can type into the command prompt screen firstboot but no response it seems
does this mean my miner is destroyed?

Nice, I just bought a working S1 to backup the data and check how the control board could be unbricked on S1 and S3.
You were faster than me.
You were faster than me.
so..... as I am not technically minded (unfortunately) does this guy win the swag in the S1 reward thread?!
No idea if the above works, but major congrats for the effort put in - it looks complicated!

You, sir, are worthy of praise for executing a fantastic idea! Nice work.

With the upcoming sale for Antminer S1 upgrade kits, I got to thinking:
what are people going to do with all those S1 blades?
And so i had the brilliant idea to begin designing 2 products to repurpose old S1 blades:
designs coming shortly, once i finish them!!
=========================================================
Anyway to help me design said items, i began poking around the S1 controller's filesystem
and managed to corrupt the two standard c library files used by normal operation. This had
the effect of rendering my S1 a several kilo brick.
So i was going: well, sh!t! what do i do now?
I tried everything i knew of to reset the S1 to no avail. I took a look at the schematics, and
behold the controller has a debug/serial port broken out on a (not so conveniently placed)
3 pin header which was (of F**king course) unpopulated.
My next thought was: do I even have a USB to UART adapter? NO!!!
To Ebay I went and purchased this lil guy: CP2102 USB to UART module
About a week later (Monday, Sept.
I got it in the mail, and promptly fired up my
windows machine for the first time in... wait was that date? 2012? dafuq?
anyway, I installed the drivers and opened it with putty using 115200,8,n,1,xon-xoff,
connected tx to rx and made sure it echoed.
Once that was set, I got to work preparing the controller by squeezing the four little
mounting clips to release it from the hashing board, disconnected all cables except power
(since i didnt have a 3.3V supply handy).
I searched through my parts drawer for a spare header of some sort. I ended up pulling
apart a 2x2 0.1" smd header to used the three pins at a 90deg angle. they dont need to be
soldered on, but it wouldn't hurt if you plan on doing a lot of poking around for whatever
reason like i am. I pressed the pins into the cables that came with the UART module,
hooked the module up and press fit the stubby part ( that would be soldered to a pad) of
the pins into the holes on the controller, minding the image above:
open putty with 115200,8,n,1,xon-xoff settings for the bridge, Flip the power switch on
the PSU for the S1, and a moment later text should go flying across the screen. This is
the controllers serial debug console. YAY!!!!!!!!!!!!
So I thought I was going to have to go through the tricky process of completely
reflashing the controller from the U-boot bootloader commandline using tftp and all
that bullsh!t.
But there is a much much easier solution using what is called fail-safe mode. It is a
special mode of the OpenWRT operating system loaded on the controller that boots from
a read-only partition of memory (which i obviously had not corrupted). To enter this mode
power cycle your S1 (no need to restart putty, all will be well) and watch closely as the
text scrolls by. It will pause once or twice. First time is almost immediately after power
is applied:
something like: Autobooting in 1 second. Hit p to stop autoboot.
This is NOT what you want so let
The second time will be during the linux kernel boot sequence. there will be several
timestamps along the left edge of the screen. It will pause and directly mention
Fail-safe mode:
type F then enter/return to start into Failsafe mode.
then it should look like a "normal" linux command prompt (if you've ever seen one, I sure
hope so if you're following this story guide). From here on it is "relatively" easy.
Type:
type:
make note of the IP address!!! More than likely it will be 192.168.1.99 or 192.168.2.99
depending on which revision of the S1 you have.
Type:
restart the controller as part of the erase procedure. Let it scroll by and continue booting.
There may be several "errors" about flash storage. thats typically ok, though. It will then
reflash the flash storage with the factory image, allowing is to boot into a clean environment.
after it seems like activity has calmed down/stopped on the screen, hit Enter/Return.
This should activate the Linux Serial console. If it does and it says something like:
then we are back in business and ALMOST back in business. Go ahead and turn everything
off, clip the controller board back onto its retainer posts, reattach all cables ( wi-fi, enet,
flat data cables, flat power cable). Power on the S1. If all has gone well, after ~20 seconds
the lights on the ethernet jack should light up. Use a web browser to navigate to the IP address
you wrote down earlier (if its on the same subnet as your network, otherwise Refer to
Section 3.1 in AntMiner Manual)
Again, if all has gone well, after navigating to 192.168.1.99, LuCI should load and present
the AntMiner Login screen. Password is
In another tab download the most recent S1 Firmware
Login to the S1. Click System Tab. Click Backup / Flash Firmware. Down toward the bottom
is a file upload section. Click it and select the S1 Firmware file and upload it (this will take a few)
The next screen is just a verification. Apply it. This should take you to a spinny screen while
the S1 applies the Firmware update. After this finishes, it should redirect back to the login screen.
Login, go to Miner configuration, Enter your particular credentials, Apply & Save, Hash away!!!

With the upcoming sale for Antminer S1 upgrade kits, I got to thinking:
what are people going to do with all those S1 blades?
And so i had the brilliant idea to begin designing 2 products to repurpose old S1 blades:
- a "hub" capable of controlling 4 S1 or 8 blades.
- a usb key, about the size of a Nanofury, capable of controlling 1 S1, or 2 blades.
designs coming shortly, once i finish them!!
