I found a bunch of files in the miner I posted above I have a feeling they could be used when flashing the machine I am curious if anyone know's what they are used for and if there supposed to be left on the miner?

If someone has a S9 or other miner they could check to see if those too come packed with the above file.

i have some problem ...

i have take this command "dd if=initramfs.bin.SD of=initramfs.gz bs=1 skip=64" and modifi this for compatibilité on "bitmain" firmware, extract, mount, modify permission for edit files, rebuild all files ok !

So, repack all files on flashable files "***.TAR.GZ", but not work ... i have needed modify runme.sh files for compatibility and force miner to flash all files ! Wink

Thanks again for your help Wink

so, i have all succes but the error FW is mini ...

I have just by pass all error on runme.sh for force miner to flash all files, and now, is working good !! Wink

You managed get it to work?

Have you run into any issues or running fine?

I noticed some files that seem to be related to flash unlocking and nand dump in the miner I wonder if they could be of some use pulling the FW.

Quite interested in what the flash_otp_info and flash_otp_dump are used for

When checking some of them for there functions I have included below.

Code:

Usage: flash_otp_info [ -f | -u ]

Code:

root@Satoshi1:/usr/sbin# ./flash_unlock
Usage: flash_unlock [offset] [block count]

If offset is not specified, it defaults to 0.
If block count is not specified, it defaults to all blocks.

Code:

root@Satoshi1:/usr/sbin# ./nandtest
usage: nandtest [OPTIONS]

  -h, --help Display this help output
  -m, --markbad Mark blocks bad if they appear so
  -s, --seed Supply random seed
  -p, --passes Number of passes
  -o, --offset Start offset on flash
  -l, --length Length of flash to test
  -k, --keep Restore existing contents after test
root@Satoshi1:/usr/sbin#

there also seems to be a way to dump the eeprom and i2c from the miner I wonder if these files are supposed to be in the miner of if they were left there when they made the V9's.

If anyone know's there use please do let me know I had a spell of dumping nand's from XBOX360s back in the day so would be interested to know more about doing this in the miner.

I have succes repacked firmware with my modified files ! but ... problem ...

i have boot my miner by SD card (contain MP Test firmware for allow install any firmware you want) ... i flash my repacked firmware, but "CANNOT VERIFY FW!!!" ...

Any idea ? i have just repacked uramdisk.image.gz files by your methode with succes on linux Wink

thanks, i have other methode for unpacking working with succes... i'm interessed by your methode for repack !

is possible you details all command for repack all ? So , the signature is not needed, just run miner with sdcard before, and after flash any firmware you want

I worked out how to pull the firmware images apart with

Code:

dd if=initramfs.bin.SD of=initramfs.gz bs=1 skip=64
mkdir rootfs_unpacked
cd rootfs_unpacked
zcat ../initramfs.gz | cpio -i

Might come in useful down the line but again I also spoke with taserz about this and to re-compile just do the above in reverse. The issue is it would not be signed so the bitmain firmware won't accept it.

For unlock ssh , the miner need have this files :

-dropbear
-dropbear_rsa_host_key
-lighttpd-htdigest.user

Thanks for the valuable information you put here, I have asked taserz to chime in with what he knows, hopefully the two of you can cooperate and find a simple way to extract a flashable firmware from an existing firmware installed on a miner, that would help a lot of members.

For unlock ssh , the miner need have this files :

-dropbear
-dropbear_rsa_host_key
-lighttpd-htdigest.user

and this code on bitmainer_setup.sh for unlock this at booting :

Code:

###########################
# dropbear
NO_START=0
#if [ ! -f /config/dropbear ] ; then
# echo NO_START=1 > /config/dropbear
#else
# rm /config/dropbear
# sync
# echo NO_START=1 > /config/dropbear
#fi
echo NO_START=1 > /config/dropbear
cp /config/dropbear /etc/default/dropbear
###########################

if i succes repack all files on flashable firmware, i want modifi all i want !!!

so is the reason i working for this

at this time i'm ok for all modifi, extract, mod, but not repack all Sad

At this time, the best methode is extract only "cgminer" and "cgminer-api" (taken on fixed freq firmware) and past on new miner if ssh is actived Wink

Do you see what I did there? that is a big if since almost all firmware versions from Bitmain come with ssh disabled, also not everyone has what it takes to move cgminer and API to another miner using SSH commands, only a handful of people can do that, I am looking for an easy way for the average joe.

... if you know how to, please tell me ! :p

This is your specialty so if you don't know, I most certainly don't Cry

, who else besides you and taserz know about this stuff? maybe we could reach out to them to see if they can help.

hi, i don't know ... at this time i'm ok for :

Extract all files by ssh (easy for all)
Extract all files on firmware, exemple, downloaded on bitmain.com

At this time, the best methode is extract only "cgminer" and "cgminer-api" (taken on fixed freq firmware) and past on new miner if ssh is actived Wink

i have my own moded files for T17 / T17+ and other ... at this time i don't know how to repack all files for make a firmware flashable ... i working for this

if you know how to, please tell me ! :p

if past modified files miner, working is ok, but one problem, if you reboot the miner, all original files are restored ...

Hi, i have recevied my V9 ... test it, and run perfect ! no rejected ... sorry man ...

Is there a way for you to extract the complete firmware image from the working miner? I have been wanting to ask you this question because it came to attention that even on other miners like the S17 pro some miners come with a fixed frequency firmware (one member here reported that) but most others (like mine) came with auto-tune firmware, so it would be great if you could explain the process of extracting the firmware from the control board.

Thanks.

Tested with "multi-version" : "4" last 4 hours still very high rejected rate but started this time round.

I look forward to you getting your V9 and testing to see if you get the same issues.

Thanks for the help.

So quick update I wondered about each of the boards on the miner and thought I would test with unplugging 2 at a time and testing them on there one.

It looks like one board is part of the cause after testing them one of the boards seems to reject a much much higher amount of shares than the other two.

This is much lower than it was so it looks like it's a fault in a board that is causing the issue.

I noticed there are some what looks like jtag connectors on the boards I may be able to hook into the board directly

I found a very interesting post where someone reverse engineered an old antminer and thought about trying this with the reject board to see if it behaves any different.

https://mightydevices.com/index.php/2018/02/reverse-engineering-antminer-s1/
https://github.com/MightyDevices/mightyminer

I am unsure if this will work as the chips seem to be different but what harm could it do the board is faulty anyway.

hum ... try change 1 to 4

just for test ...

on my idea ... bitmain have include Asicboost on firmware, but, V9 have "S7" hashboard reconditioned ... and not compatible ...

"multi-version" : "1" (no asicboost)
"multi-version" : "4" (asicboost actived)

just try ...

coming soon i receved one V9 model ... i have only buy this for psu lol , but i run it, if i have same problem, i work for this for try discover the problem Wink

I added the line in the conf but now the miner won't start to mine I checked in the gui and everything is missing from the config page I attempted to start cgminer from the cli pointing to the /config/cgminer.conf file but the miner starts and runs at only 1.1 TH it's like only one board is starting.

Another things I noticed was there us never any WU or Bestshare showing in the GUI or CLI I think bitman sold me a bunch of faulty miners tbh.

Any other idea before the claw hammer comes out.

Thanks again

Thanks, add this line ""multi-version" : "1""

so ,

Code:

{
"pools" : [
{
"url" : "firstpool.com:3333",
"user" : "3SsoMeBtCaddRe3S4pY2HbYoX5PnhGuSt3s.Worker1",
"pass" : "x"
},
{
"url" : "stratum+tcp://2ndpool.com.com:3333",

"pass" : "123456"
},
{
"url" : "stratum+tcp://somepool.com:1234",
"user" : "z9z9z",
"pass" : "x"
}
]
,
"api-listen" : true,
"api-network" : true,
"api-groups" : "A:stats:pools:devs:summary:version",
"api-allow" : "A:0/0,W:*",
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50",
"bitmain-use-vil" : true,
"bitmain-freq" : "533",
"multi-version" : "1"
}

modifi your cgminer.conf, and reboot miner (no apply on config webgui for old the new settings) ... just try it

Thanks here is a copy of the cgminer.conf file I have changed some of the info I have SSH access to the miner bitmain have not locked down the V9 range with there firmware from what I can see.

I will send you a dump from the miner's webgui via PM also.

/config# cat cgminer.conf

Code:

{
"pools" : [
{
"url" : "firstpool.com:3333",
"user" : "3SsoMeBtCaddRe3S4pY2HbYoX5PnhGuSt3s.Worker1",
