Hello unpainted.
Are you familiar with using a jTAG device with a 6 pin probe attached?
If so, I can send you a copy of my LV07 v1.0.0 backup factory firmware and you can flash your LV07 back to life with the jTAG and probe.
If you take off one of the metal panels on the LV07, it's the one on the left if you're looking directly at the LCD screen, you'll see the jTAG probe points.
I bought both the jTAG and 6 pin probe from AliExpress.
I did the same thing as you and tested several other firmwares on the LV07. But because I learned how to flash my Bitaxe MAX (which has no USB port) and LV06 using the jTAG, I was able to revive them! Luckily I had 2 other LV07 miners and I saved a copy from one of them and flashed it back to the non working one without any problems. The only mistake I made, was not making a backup of my LV07 first before I flashed it as it was my newest LV07 with the newer 1.1.0 firmware!

Hey, I'm looking for the original firmware for LV07, it could be version 1.0.0 or 1.1.0, can you get it for me? Thanks.
This is an interesting thing that happened to me.
I have three LV07s. I successfully installed AxeOS on them, and everything works on two of them.
On the third, the ASIC chips aren't being identified: ASIC STATUS: Chip count 0
What I did was remove the heatsink, and now the chips are identified, but I have a problem with the TPS546:
TPS546: Status: 0x4851
TPS546: The voltage regulator is turned off
TPS546: An output overcurrent fault has occurred
TPS546: TPS546 IOUT Status: A0
TPS546: IOUT Overcurrent Fault
TPS546: IOUT Overcurrent Warning
TPS546: The output voltage is NOT within the regulation window. PGOOD pin is asserted.
I believe it's due to excessive power consumption on one of the chips.
I didn't test this LV07 with the original firmware; I flashed it immediately.
Do you think it could be something with the firmware or hardware?
Thanks.
