Old S9i - want to change to doge mining : HOW ?

many of you may say WHY ? Grin

im playing - i have bricked this S9i ,
tried to reinstall antminer firmware and now just
get a page that says :

tried to install braiins , getting nowhere

so radical change of tact required , lets try a totally different
firmware etc , it was working pretty solid until i messed with
it except after a few hours it seemed "break" and fans would go
FULL speed for no apprent reason so i decided to reinstall firmware

No there is no way to mine Doge using Antminer s9i because this miner uses SHA256 algo and mining Dogecoin uses Scrypt algo which is too different you can't convert the firmware to mine Dogecoin ASIC manufacturers produce miners only for specific algo.

Oh ! thanks

i thought i read somewhere you could put different firmware on it to change it to scrypt instead
of sha 256 , maybe im wrong

Oh what am i going to do with this unit now !

anyone recommened any easy to install easy to download , plug in play firmware
for anything on an S9i

Nope, that's not possible. You will never be able to convert an SHA256d ASIC to a Scrypt ASIC. The chips are not the same.

About your question on the firmware, why not using Bitmain's official firmware ? Otherwise, as you mentioned it, BraiinOS is plug and play. If you have an issue with BraiinOS, you can go on their official topic and ask for some help.

It depends. If you have cheap electricity, why not joining a pool and mine BTC ?
If you have almost-free electricity, you can use it as a lottery ticket and solo mine BTC on ckpool / kano pool.

If you aren't profitable, if your electricity is expensive, you should maybe turn it off.

Hey thanks for reply !

ok thats clear , no doge mining :-)

I fully understand its a lottery at the TH levels im pushing , electricity is mainly
free off solar.

I have tried antminer official software and braiins install , both have failed to take
i think i have bricked it , not sure how to move forward

Are you still able to access your ASIC from his IP ?

If you want you can share with us the kernel log of your antminer, maybe we can help you to identify what is the problem

Without your miner's kernel logs, we do not know what exactly happening with your miner.

I suggest flash it back to stock firmware and then run it for a while then go copy all kernel logs and paste them here just put it inside the insert code tag.

Also, make a screenshot of your miner status and upload it to imgbb, and paste the URL.

Currently i cant get IP address
but i have tried several different items from
bitmain support when the files that were supposed
to did not work , i will experiment further in due course
but currently its goosed

I do have a question that might help me as i am not sure about
it

when you copy the firmware files over to SD card , do you extract
them to the card or just copy them over
Even when i extract them over to SD card , some of the files
are still zipped on the SD card , its confusing

Quote from: koinkab on July 07, 2023, 12:12:39 PM

You have to extract the file on the SD card, but it is 100% normal that some of the extracted files are stil compressed, no issue with that.

Did you follow these steps ? Did you do all the steps including the ones with the jumper to move ?

https://support.bitmain.com/hc/en-us/articles/360019493654-S9-series-S9-S9i-S9j-S9-Hydro-Control-Board-Program-Recovery

Did you give a try with the following step too ?

4. Unzip the downloaded t9+-SD Tools.zip and copy the contents to the MicroSD card.

While you were typing that i was away trying something

i will come back and follow your instructions shortly

by going to bitmain an downloading " S9i SD card recovery image.rar"

i have now got a page that says "ALTERA board update portal " on the IP address

Typical , the jumpers are "just" out of reach im going to have to dismantle
the unit to access , likely need to wait to next week.

Is there any firmware i can put on an SD card that will start the unit from the card
without having to fully reflash at this stage ?

That's the reason why it can't flash through the SD card you just forgot to move the jumper.

About the firmware that you can boot through an SD card without flashing the control board, Bitmain doesn't have a firmware like that but BraiinsOS have a firmware that you can boot without flashing the control board.

However, you still need to move the jumper to boot through the SD card.

Ok
i moved jumper im not really moving forward
I think its best to start new thread to ask for baby steps
going through this
