Dear Miasma,

We are waiting for testing results of the S4 sample machine. Hopefully there will be good news before next Tuesday.

Cool. But what is L1, appeared at your website?

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.
(http://www.aliexpress.com/item/AR9331-module-support-openwrt-platform-support-the-Internet-of-things-applications/2000720631.html)

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

https://dl.dropboxusercontent.com/u/2113596/0-Miner.png

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

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:

https://dl.dropboxusercontent.com/u/2113596/IMG_20140831_212859829.jpg

Now connect the serial port to use an Arduino one that can become a Serial to USB converter only by bridging from RESET to GND and the Arduino board are clearly where the RX, TX, GND to the serial port.

https://dl.dropboxusercontent.com/u/2113596/IMG_20140831_212848867.jpg

Then it was just a matter of connecting it to the computer and see what happens in a finish as Minicom or Hyperterminal, I use linux for all these things then for me it was easy, just had to run the command:

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.png

When 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.

Excellent even though its not tested myself.

Quoting big ass posts with picture makes you lose at forum skills.

Did it to have a copy of it for myself even if he delete the post for what ever reason.
I replaced the images with link.
PS: I have a thread in hacking the control board. So it may some how help in that.

That makes sense. Sorry for my ass reply then.

Dear Mister BitMan,

We need to know when to expect the S4  

Absent news it's time to buy SP31s.

Dear Miasma,

We are waiting for testing results of the S4 sample machine. Hopefully there will be good news before next Tuesday.

Look forward to hearing it. I guess your competition is Hashra: http://hashra.com/moonrakerwarp3/

not really no.. Thats just 3x 1ths boxes.. if you read their description a moonrakerwarp3 = 3x moonraker boxes. So you'll spend 12u for 3ths.. thats been done for a long time.

"spend 12u for 3ths" Are you talking about rack units 
I don't waste money on racks. I care about $ per gig and Watts per gig.

What is the BitMain L1?

Edit: Sorry it's been asked and not answered, that I can see.

BitMain L1 is not an announced product.
They can simply delete that entry or can announce it as a new device.
If we do some speculations, we may consider the L1 as L for Litecoin so it as a scrypt miner.
And another way we can say it as zero cost advertisements for their yet to release a product.
They are expecting these kind of speculation to get free popularity. Someone even opened thread for this.

Hashrate is also displayed in MH/s so probably a scryptminer.

[ChuckBuck]

Wow, Bitmain making moves!   

First, worldwide miner domination with the S1, S2, and S3, now potentially a Scrypt miner and a cloud mining site in Hashnest?!!

Mining for ROI maybe too difficult to non existent, but out of all the companies and manufacturers, at least Bitmain makes it feel like you have an outside chance.

Definitely exciting news.

[samsonn25]

IMHO they are trying out another revenue stream.

BTC mining for roi is dead,

they dont stock items anymore, they are special order.  They are selling off farms from s1 and s2 machines because they are not efficient anymore.  S3 are next. S3+ will return .15 btc.

We are waiting for testing results of the S4 sample machine. Hopefully there will be good news before next Tuesday.

So I guess there were no good news then?

Hello Bitmain,

I see you have uploaded the latest cgminer source code here:  https://github.com/bitmaintech/cgminer

Can you please tell everyone how to upgrade their S2 & S3 miners to this latest version with the security fixes? Or are you releasing a new firmware for the S2 & S3 that will include this cgminer version?

Many Thanks, IYFTech.

Hello Guyz,

Cool Some news about the L1 just popped up

"Our brand new, high-performance L1 will be hashing at 120MH/s
with the market-best pricing of only $599.00 USD per unit with free shipping worldwide"

Sales open today and delivery is only on December that's 3 to 4 months and so its a pure Pre-Order.
These days buying miners are too risky since the ROI marginal for most.
More over the Alt coins are different than Sha256
In bitcoin the profitability can be predicted but it Alt its not that easy.
Hope this Antminer L1 might workout. Also note the below statement by them.

Moreover, the miner will be able to mine multifarious scrypt based altcoin, of which scrypt length can be 1024, 2048, 4096 (n = 10, 11 or 12).

[upstart7]

I found Hashnet a bit confusing, and in general does not seem like a great ROI. I like the L1 scrypt miner they have recently announced but will take a wait and see approach. Not a fan of pre orders. They have good track record for delivery, never had to deal with RMA with them ( count myself luck).

December?!!

Ugh, gross.  I thought it'd be closer to this month or October at the latest.

Although, it's a good price now, that could all change once KNC Titans finally drop and spikes the whole Scrypt mining hashrate and difficulty.

Disappointed that Bitmain is going the preorder route.

Which exactly are those altcoins beside LTC L1 could mine? Is there a list somewhere?

Absolutely. Can you clarify please Bitmain?
