No other solutions apart from sending it back, I am the one who discovered the manual flashing of the PIC controller, and I can confirm it works.
can you please explain how to do that ? |

hey everyone after getting a new circuit board for my antminer l3+ after install it no hash board are detected... the blissz firmaware was installed for a d 3 miner i think.... even after flashing it with the rigth firmware no hash board are visible. so i put back my old one and now not even this one is detecing any of my cards .... im so lost.... can the new circuit board have mess up my hash boards  really dont know what do to cause i already did both way of flashing it ... please let me know |

You can call it virus ,that's fine , let say its a virus what 'crypto jacking" your miner  Be careful if you have one ASIC " infected " and you have more than one ASIC , within a short period of time all of your ASIC will be a "crypto jacking victim" , or we can say infected with a virus  If there is no signature protection on the firmware you are using, that "virus" simply gets through the ASIC firmware script. To protect your ASICs from getting infected, install Bitman firmware (released after December 1, 2019) all on your asic you have. The network device password and ASIC password always must to be different ! If the infected ASIC gets into the network, it will infect the others despite the firewall. HERE IS some info for you , How to Save your ASICs , if you know how to run some commands thanks for the advice.... i will keep it in mind and look at the link posted. at the moment i got only 1 so i guess by getting a new circuit board and changing the passoword ill be fine. i will let you know and thanks again all of you for the support if you ever pop by in barcelona let me know and ill take you around  |

few days ago i got my first new l3+ and stupid me i havent change the passoword so he got hacked.... i try to flash it with an sd card of 16g but nothing happend...at 19.00 my local time take over the miner and change the pool address... i dont know more what to do... i download the last l3+ firmaware and flash it.... but maybe i did somethings wrong .... do the internet cable need to be connected during the flashing??,,, and after its flash ... how can i see if he really did it ? maybe its the sd card its new...but 2 or 3 times i disconnected just by pulling it out but after i have been format it at 32 fat and place in the file ... im kind of lost... Your ASIC is a cryptojacking victim its not a virus , someone gained access to your miner , and changed some settings there , redirected the hash power to his own account probably , even they can lock you out from your own miner .... My suggestion is completely reinstall the Latest offical Bitmain Antminer L3+ software on your asic from SD card Instruction how to do the firmware reloading from SD card is HEREAfter reinstalled the software , make sure you are not using the default login information. Also... if you have a static ip , try to change that ip somehow ,call your internet provider and ask them to assign a new IP for that location. thanks for the advice but its a virus as bitmain sad too..... i try everything... i cant flash it in anyway... i even shorted 2 points on the circuit board begore flashing it....but nothing.. at 19.00 mytime the virus kicks in and the pool addreess are changed.. im buying a new ciruit board....as also bitmain adviced if the shorted process will not work the board need repair. |

its seams its a very nasty virus... i even short out 2 points on the board prior the flashing... and now dosent even turn on both led ligth when is done like before.... bitmain said it too... if the sorting the 2 points dosent work the board need repair.... i already got one form east europe and will be here next week... i will try a new sd card but seams is like the corona virus of the miner.... |

You should post what chip voltage and frequency setting you are using, as well as the kind of firmware and the numbers of errors per time (i.e. hour or day) you get on the boards.
If the whole board gets XXXXX it can be a sign that your frequency is too high for that board and/or the chip voltage for that board is too low.
If the whole board disappears from the Web GUI it can be a sign that the PIC controller on the hash board needs to be reflashed.
HTH
how do i flash the pc controll of the hash board ? thanks very much for all your support guys you are super cool Check this topic for more information: https://bitcointalk.org/index.php?topic=2383200HTH thanks... i took a look at it but with no image its very hard for me... i saw before the blizz program recovery videos but they do not plug any board on it and i heard i should use only bitmain... i have now flashed with the 2019 firmware with the sd card but if i try to do it true the mac it tells me it cant find the file. i had a virus changing the pool ip. how can i know if the firmware was updated ?? in the miner bio i can read the system is from 2019 but i dont know if was like this before . can be that im using my mac to upload the firmaware eventhou im using parallel and windows 10 with edge explorer ? |

Here's the issue you may have , hashboards are not recognized, anymore  /!\ please read carefuly /!\**************************************************************
Firmware Flash
************************************************************** Here's a fix solution to rewite PIC's of L3+ after some of us flash bad firmware to their L3+.Many has recovered 3 boards , some all of it Thanks to Blissz for this fix (please do not pm him for this ) 1. Download File(re-up) WARNING: Don't flash this to anything else as a bricked L3(+) caused by flashing a wrong firmware version, as this might harm a working L3(+).MEGAor 1fichier 2. Plug only 1 board from chain 0 (white cable on the left) as you can see under , you can plug upper hashboard 1st 3. Go to system -> Upgrade -> "Flash new firmware image" choose the file downloaded to flash new firmware and click flash image wait for reboot. If kernel logs get this ... 0xcc , wait after you see it ( 5 minutes, to see again 0xcc or most of time 0x3 and then it will fix your board) other way try to connect an other boards and restart from "3" Dec 17 14:09:30 (none) local0.warn cgminer: Started cgminer 4.9.0
Dec 17 14:09:30 (none) local0.notice cgminer[377]: detected at /sys/class/gpio/gpio51/value chain 0

Dec 17 14:09:30 (none) local0.notice cgminer[377]: i2c init ok
Dec 17 14:09:32 (none) local0.notice cgminer[377]: Chain 0 PIC Version 0xcc

Dec 17 14:13:51 (none) local0.notice cgminer[377]: Chain 0 PIC Version 0x3
[...] you will see some logs like this , PIC's is currently writing. Dump IIC Data:[41][98][0][0]@ChainID:[0], Chip[C9] wait logs "miner start and switching pool" the board has been flashed with success. After fixing all or some of boards , you can finaly flash back bitmain l3+ original Firmware.**************************************************************
Manually Flash
************************************************************** /!\ I will not assist with "how to" here cause i didnt experience it yet but if you have stuff (pickit3) and knowledge to manually flash chip of your miner here's the files ! warning ! have a look to the pic version you have (writed on the chip). there is PIC16F1704 or PIC16F1705 Here's the hexa files for each version MEGA PIC16F1704.hexPIC16F1705.hex1FICHIERPIC16F1704.hexPIC16F1705.hexThanks to martin_fryc for sharing files, after succefully fix his L3+ by manually flashing PICs************************************************************** where are the images ?? and do i need to plug only 1 hash board to the circuit board ? and which version should i choose ..based on what ?? |

flashing the pic controller its the same as flashing the intere miner ? No, that is not the same. If you have the option for repair, I would suggest to send the faulty hash board back. In the meantime you can still use the miner with the other 3 boards. i have now flashed the circuit board with the 2019 firmaware but once again when i try to upload the firmware it tell me the 404 error message had it into another tap... im using the mac but with parallel using windows 10 and edge explorer ... why cant he find the file ?? should i try to use a normal pc ?? or is something else ?? |

how do i flash the pc controll of the hash board ? thanks very much for all your support guys you are super cool |

but how is it possible that my mac got infected???
Who told you MAC cant be infected with virus ? i know its a kind of myth.... but i never experience nothing in 9 years , anyway i run avast and he got something but i dont think was the virus... what can i do to fully clean it |

Prob has the Nicehash FIRMWARE wich was known to be "manipulated".
the Custom FW from nicehash has a backdoor were this scammers let them change your mining settings.
It was aknown issue and thats who nicehash started, they were focused on custom firmwares at the beggining rather than pool.
the Nicehash firmware backdoor can be removed by flashing to org bitmain firmwares , you need to clean the entire memory from the controller board "BBB".
201904231534-L3+-SD-recover-NAND.zip 179.31MB L3+ SD card firmware 2019-05-14 is this one i need to flash the miner with the sd card? its from the bitmain firmware |

flashing the board with the firmware by sd card today i did flash the board with the card and then i try to upload the new firmware but wasnt possible. i saw in the l3+ firmware the first in the list its described as sd recovery from 2019 should i use just instead ? |

No as the virus will reload its self..
the sd card will erase the virus (maybe) if you are lucky.
or you need a new controller.
depends on how good the virus is
screen shots would help us
ok thanks can i use my mac or i can only do it with pc with windows i also found out of a bitman antivirus but also said i need windows 7 or higher.... do i need a pc ? you can do stuff on mac and use chrome or microsoft edge browser. I have not had much luck using safari browsers last year or so. ok thanks i will try ..... but what you mean ... hasnt work for you ?? my macminis have safari chrome microsoft edge firefox I cant get great results running safari. But if i use chrome or microsoft edge. it works on the mac minis. yes thanks i manage to use to mac as a pc.... but the miner still infected.. i flashed with the sd card and then i try to upgrade the firmware but didnt aloud me.... and after a while startrd again to log into the nicehash pool. |

There are internet bots that search for ASIC miners that have not had their factory password changed and then change the internal settings. A factory reset to the device while on a LAN not connected to the internet and then a password change might do the trick.
ok thanks i will try but how can i connect the antminer to the lan but not to the internet ?? i also realized i need a pc..... cant do it with the mac |

it happen again now with my phone ....  cant i just flash the miner true the webgui with out open the miner ? |

I would suggest you move this thread to Mining (Altcoins) If you want to get much more audience and more replies from people who are more familiar with mining and the AntMiner L3+ The option to move topic is on the bottom left of your topic. Which store sold you the miner? ok thanks i will try i got the miner from a chinese company well known |

flashing the pic controller its the same as flashing the intere miner ? |
