Exploring the Future of Immersion Crypto Mining Techniques

Welcome to a step-by-step guide on the upgrading of the Bitmain L3 Plus Plus from the stock firmware to Hive OS’s firmware. The Bitmain L3 Plus Plus, as you might already know, is a script miner used for mining Doge and Litecoin. But why upgrade the firmware and why Hive OS? Well, Hive OS’s firmware not only allows you to monitor the miner, but it also has features that make the miner more efficient and use less wattage.

Tools Required

A few things will be required for the upgrade. To start with, you’ll need a USB adapter with different card slots, including an SD card or a Micro SD card. This adapter will help you plug the USB into your computer to flash and access the files on your SD card.

The second item on the required list is an SD card. For Bitmain L3 Plus Plus, you need a card under 32 gigabytes in capacity for this upgrade. Remember to have the SD card and adapter ready before beginning the upgrade process.

Understanding Bitmain L3 Plus Plus

The Bitmain L3 Plus Plus has an 8-gigabyte SD card. There’s a control unit which carries multiple hash boards along with two fans to cool down the system. The control unit has an SD card slot that we’ll use for the upgrade. Besides this, the L3 Plus Plus comes with a Bitmain power supply unit, which is fairly quieter than most others in the market.

Upgrading to Hive OS’s Firmware

Step 1:

The first part of the upgrade will involve unplugging the fans and the cables running into the control board from the hash boards.

Step 2:

The second step is to undo the screws at the front and carefully pull out the control board to access the SD card slot.

How to Flash Firmware

Locate the SD card on your computer and format it to FAT32. After that, you will download the required ASIC firmware from hiveon.com. Extract the downloaded firmware and copy it onto the SD card. You have now successfully flashed the Hive OS firmware on your SD card.

Step 3:

Insert the SD card into the control board, ensuring the gold pins face upwards. Then, plug in the power supply. Remember not to plug the ethernet cable in just yet.

Jump on to your computer and locate the IP address of your miner. Load the IP address on your browser, and you’ll notice the firmware change.


You can now disassemble the control board, re-attach the fans and the hash boards, and then reassemble the L3++. Connect your L3++ to the power supply and, finally, the ethernet cable.

Step 4:

Move on to your Hive OS account and attach the L3++ miner to the account using the “farm hash”. You can find the “farm hash” in the setting section of your Hive OS account, right beside the rig list.

Return to the IP address of your miner on your browser and click on Hive OS. Insert the “farm hash” and click on “apply”.

Result of Upgrading

You will now find the miner listed on your Hive account. Keep in mind that initially, the miner will mine to the default Hive OS wallet. To change this, simply create a new flight sheet indicating the wallet, miner, and the pool of your preference.

Under the overclocking tab, you can set it to 504 Mega hash at 660 watts, which is a huge win compared to 580 Mega hash at 942 watts.


So to sum it up, upgrading your Bitmain L3 Plus Plus with Hive OS’s firmware is extremely beneficial and easy with this step-by-step guide. You get the advantage of central management and efficient mining.

  1. hey there, i need some help… mine was just light red and blue of the board on for 1 min, then red light flashing for a min, then still for 5 secs then green light flashing

  2. I just picked up 3 L3+'s this week and found this video and upgraded all 3 to the HiveOS Firmware. After doing so and running a few days on ProHashing, I noticed I really wasn't making hardly anything. Started digging around and found out that Hive has a built-in "Dev Fee" in their firmware. i.e. Hive is sucking out around 3% in the background on each miner running their firmware.

    So, all these Youtuber's out there promoting to install Hive Firmware are probably getting paid to promote it. Because NONE of them are telling about this hidden fee. They state that the Hive Firmware is FREE…however, it is far from free. They are charging you in the background.

  3. side notes for using HiveOS :
    HiveOn Free account – an account with a total of 4 or fewer workers (under certain conditions), excluding ASIC with Hiveon firmware.
    The firmware charges a dev fee. This is done in parallel mining, without hashrate dips or suspension of the main mining process:

    L3+ / L3++: 1.8%

  4. @thehobbyistminer – great video! I have 4 GPU rigs on my Hive account already so I have maxed out the free account limit. If I add one of these ASICs, will that put me over the free account limit and activate all of them now to charge me each month? Any ideas here and hope that makes sense?

  5. just so you know, for if you have to do another , you dont need to take the screws out to slide the control board out , just hold the clips open and it will slide out 😉

  6. So I know the hashrates are different STOCK on the different submodels for the L3, my question is how the hashrates change on hiveos firmware, are you still getting 504mh on the 660 watts for the L3+ 504mh model?? Can't seem to find the stats on those submodels…?

  7. People that Use Mean Well AC-DC Single Output LED Drivers for Power , Get far better performance , than if they use the China Drivers, most Things use China Drivers for Power, Mean well Drivers, made in the USA, are a lot more power efficient ! I think its the DC, Current that provides more efficient, it does not Wave like AC. Eddy Current ! Does Mean Well Make a power Supply for Your Machine ? i bet it Does. I Notice China Writing on the Power Supplies Used by minors. Maybe I am Wrong, But pot Growers Prefer Mean well Power Supplies for the Grow Lights…

  8. How did u get to 400 ish watts? I did same thing and I’m getting 660w 504 mh? Did you adjust any other settings? GREAT VIDEO BTW very informative and easy to follow!! No BS and straight to the point!

  9. I would be interested in what the firmware does on a L3+. At this second, I see 548mh, 24 hour average of 519mh , at a setting of 400m, lowest voltage, 702 watts, using BlissZ, Litecoinpool. I can get lower power usage 387m and lowest asic voltage, 680 watts using an HP 1200 watt platinum HSTNNS-PL30 but I'm not real sure of the 24 hour average.

  10. I had (3) L3 + on them using hiveos and litecoinpool. The firmware would always state that 500 hashrate at around 600 watts. They never averaged over 500 on litecoinpool. Actually they were around 450 475 over 24 hours. But the user interface always claimed over 500. So I stopped using hiveos. Even with a fee, that's way more than stated by hiveos. BE CAREFUL! using their asic firmware.

  11. Hi, Bro! thanks for that amazing video!! greting from China and I am your super fans. i wondering to ask you maybe could make an video for building an Aleo node?

  12. I just picked up a couple L3+ 504m units recently that had the HiveOn firmware on them. The dev fee was taking more than the quoted 1.8% on my two, even after updating to the latest HiveOn firmware, so I ended up switching to a different firmware that doesn't charge a dev fee. Still has the fan control and overclocking and undercoating features, so I'm glad I made the switch. For the noctua fans, you can use a pair of flush cutters to remove the inset tab off the noctua fan connector, that way you keep the tab on the control board fan header to make sure you plug the fan in correctly.
