Thanks a lot bro, my amp worked immediately after installing the firmware on a new Micro-SD card. It's nice to bring the amp back to life after a long time. Please don't delete this firmware from Google cloud, it will allow other people to bring their amps back to life from brick state. Here are a couple of tips: Do not edit or modify internal presets on the amp itself or save them in the amp itself, this destroys the firmware. It is best to save the presets you create to the My Tones folder.

Here some photo of back side of power suply. It,s make on my smartphone, not the best quality.

I'm taking the amp apart this weekend to get to the power supply. I'll take a picture of the board and post it here.

Can you guys share the firmware file from your Amplifi 150 micro-SD flash drive? Please copy it bit-to-bit, post it somewhere in the cloud. I will be immensely grateful. You will help a lot of people to bring back to life an amp that turned into a brick.

Try updating the Amplifi Remote app for Android by downloading this Line6 website. They have recently updated this app. I have version 2.61.0 installed, Android 13.

Over the weekend I tried to re-flash the amp again using a 4GB disk image, and this is what I ended up with. 1. The micro SD card is not always read and started on the amplifier. Sometimes I had to use different disks, 4GB and 8GB, reflashing several times. I think the problem is not in the computer and not in the cards, because I use high-quality cards SanDisk, Kingston, and recording bit to bit. Flashed in Windows 11 and MacOS Mohave, on a desktop computer and laptop, all equipment is fully operational. 2. On the third or fourth attempt to rewrite the card, the amp reads the card and starts up. 3. I didn't touch anything, didn't run bluetooth, didn't change or edit the built-in presets. Just used it as a monitor speaker for my computer via USB, and connected my guitar directly. In this mode the amplifier worked for half a day and switched to the mode when all four LEDs start blinking. 4. Attempts to make a factory reset by pressing the tone and volume buttons of the amplifier lead to nothing. 5. Attempting to reflash the amplifier via the USB connection also does not help. After a complete re-flashing of the amplifier after turning on the amplifier again goes into the mode of blinking four LEDs, factory reset does not help. 6. Apparently, I will have to disassemble the amplifier again, pull out the microSD card and reflash it again. I conclude that this is due to some kind of software malfunction, i.e. the amplifier somehow corrupts the firmware and turns into a brick. Please share your thoughts, everyone who tried to reanimate the amplifier on their own, maybe there is a poor quality part on the motherboard that spoils everything, or some glitch, but what is it? If someone has an amp that doesn't have these problems and has been running stable for a very long time, please take a firmware image from your Amplifi 150 MicroSD card and post it in the cloud. You will help a lot of people and make a lot of people with amplifier problems happy!

I have the same situation with my Amplifi 150 amp unfortunately. At intervals the amplifier goes into firmware update mode, when all four LEDs blink. The last time I reflashed the MicroSD card with firmware version 2.60, the amplifier worked for about three weeks and then suddenly turned into a pumpkin again. This is unpredictable behavior. Maybe the flash drive is randomly writing garbage code during operation, or the bluetooth connection is affecting the operation, or some components on the motherboard are unstable. But during these few weeks I have not noticed any problems with sound or tone quality. I'm using a USB connection, outputting sound from the computer to an Amplifi 150 amplifier. I use both macOSX Mohave and Windows 11x64. The only thing is I don't change the built in presets or save them to the amp. I save all newly created guitar tones to my Android phone in the My Tones category. I'm going to try reflashing the firmware again this weekend and see how long it lasts without another crash. I use 4 or 8 gigabyte cards.

Friends, hello, everyone! Can anyone post the MicroSD image from their 100% working Amplifi 150 amp? Here on the forum there is a firmware image from Amplifi 75, but I'm not sure that it will fit Amplifi 150 1 in 1.

I'm afraid Line 6 has buried the Amplifi line of amplifiers and it's pointless to wait for help there. And there has been no warranty for several years. Today it is not even possible to order a new motherboard from resellers.

I have a problem with my Amplifi 150 amplifier. Every 5-10 minutes the amp reboots, sometimes with a very loud short whistle at full power. Had no problems for several years before, everything worked fine. I updated the firmware several times. The firmware is now firmware 2.60. I did a factory reset after that, but nothing helps. I don't activate Bluetooth, I don't change or edit presets. I use only direct connection to the guitar and connection to iMac 27 computer via USB. Have any of you experienced this problem and how did you solve it?

It's so funny when the admin edits my text and replaces the word poop with lollipop. This adjustment will not magically transform the amplifier from Cinderella into a princess ...

Friends, hello everyone! I am writing to you via Google translator, since English is not my native language. So, I have a Line 6 Amplifi 150 guitar amp. It worked well enough and I didn't expect any problems. Installed the latest firmware 2.60 and everything worked fine. After a couple of months, the amplifier suddenly, when turned on, went into the mode of simultaneous blinking of four LEDs. Sometimes they just blinked, and sometimes they burned constantly. I reset the amplifier to factory settings by holding down two buttons - volume and tap, and after that everything worked until the next failure. The last such failure permanently disabled the amplifier. I decided to try to fix the problem on my own, since there was no desire to pay several hundred dollars for repairs. I carefully disassembled the back wall and, having disconnected the wires, removed the entire rear module. The power supply board is located on the bottom of the amplifier. It has a 220 volt input and the following voltages output on the front eight-pin connector. Pin 1: +8 Volt (For powering the motherboard) Pin 2: Ground Pin 3: +19 Volt (For powering the satellite speaker amplifier) Pin 4: Ground Pin 5: -19 Volts (For powering the satellite speaker amplifier) Pin 6: +48 Volt (For powering the center speaker amplifier) Pin 7: Ground Pin 8: -48 Volts (For powering the center speaker amplifier) I checked the voltage data with a multi-meter and made sure the power supply is working. After that, I carefully peeled off the glue from the Micro SD card and pulled it out of the slot. 4 GB card. I turned on the amplifier without a card, nothing happened. I put the card back in and turned on the amplifier again, but it didn't work. And then I decided to replace the card with another and reflash it again. I only had 16 GB at hand, I pulled out the old card, inserted a new one, and holding down two buttons Tap and Tone turned on the power. The amplifier has entered the firmware installation mode. After that I installed the latest firmware 2.60. The installation went well, there were no problems. After installation, I reset by holding down the Volume and Tap buttons, and the amplifier turned on to its normal mode. Everything worked. But now periodically, not very often, but sometimes several times the amplifier independently during operation resets to the factory settings and turns on again. At the same time, LEDs 1 and 4 light up (only 1 and 4). They blink several times and a reset occurs. I don’t know what it is, but I’ll figure it out. Perhaps the system does not like the SD card, and I need to install 4 or 8 GB. Maybe bad cables or bad contact somewhere. I will say one thing, I have not yet met such an so expensive, unstable lollipop. Build quality and components are terrible. What the sound is lollipop, what the amplifier is lollipop. I was fooled by the high-tech design. Good luck to everyone, guys, if I can find out anything else, I'll write here.
