Logitech UE Hyperboom: iFixit UE Hyperboom battery not charging (BMS?)

Wed, 15 Jul 2026 16:19:49 -0700

I am having an issue where my two different replacement batteries for my original Logitech UE Hyperboom battery will not charge. I have already tried the standard troubleshooting steps including checking the power adapter, inspecting the DC power socket, and ensuring all internal connections are secure. Despite these efforts, the device still refuses to take a charge while the original battery is recognized. I believe any Battery Management System included with the iFixit battery is not being recognized by the UE Hyperboom. Has anyone else been able to get a UE Hyperboom to recognize the iFixit BMS and charge the battery? If so, what steps could I follow to get the replacement battery to charge normally?

Logitech UE Boom: How can I upgrade my firmware if the app doesn't support the speaker?

Sun, 12 Jul 2026 14:47:42 -0700

It's the 1st edition that came out. I own two of these. Want to connect them to stereo.

Don't know if a firmware update is needed or not.

THe UE Boom app is useless for them.

Logitech UE Hyperboom: UE Hyperboom replacement battery not recognized - flashing light every 40 seconds

Wed, 08 Jul 2026 12:40:35 -0700

I am on my second replacement battery (one from iFixit, one from another source) and neither will charge or allow the speaker to power on. When the iFixit battery is installed, the charging light/power button flashes approximately every 40 seconds, but the battery is not recognized and does not take a charge.

I have already verified that:

1. The battery connector is firmly seated on the motherboard.

2. The original battery still works, confirming the speaker's internal hardware is likely okay.

3. I have attempted a factory reset (Volume Down + Power) for over 30 seconds with the new battery installed, but there was no tone and no change in behavior.

Has anyone successfully gotten a third-party or iFixit replacement battery to work in the Hyperboom? Is there a specific "handshake" or firmware step required for the BMS to accept a non-OEM battery?

Logitech UE MegaBoom: UE Megaboom will not charge (light still flashing)

Thu, 02 Jul 2026 07:21:29 -0700

I haven't used the Megaboom for 6 months, took it out of storage and used it for the last couple of days while I was working outside (still had battery that lasted two days). Once it went flat, I plugged it in to charge overnight, the white light was flashing as normal. In the morning, I tried to turn it on and it said "Critical battery, please charge". While charging, if I try to turn it on, it just says "Charging, please wait". It still won't work no matter how long I leave it charging, though the white light is still flashing as normal. Is the battery toast? I did use it outside on a day with a lot of fog

Logitech UE Boom: Why does my UE Boom require 3+ attempts to connect?

Fri, 22 May 2026 23:11:42 -0700

My UE Boom seems to consistently require three attempts before a Bluetooth connection is established my laptop (MacBook m1, up-to-date). Anyone know what is causing this and/or how to fix it?

Steps:

Turn on laptop (defaults to Bluetooth on) and UE Boom (previously paired).

First attempt. Connect laptop to UE Boom via laptop toolbar. Fails to connect. This sometimes 1-3 times.
Second attempt. Turn on UE Boom and try to connect via laptop toolbar again. This results in UE Boom turning off instead of connecting.

Third attempt. Turn on UE Boom and once again try to connect via laptop toolbar. This time the connection is made and UE Boom behaves normally until turned off.

UE Wonderboom: Speaker turning itself off

Fri, 15 May 2026 17:52:12 -0700

I just got a new UE wonderboom speaker off of Amazon, fully charged it, and now when I try to play music through it it will turn itself off after playing for a few seconds. I’ve tried a default reset and removing the device from my phone, any ideas on what to do?

UE Wonderboom: My Wonderboom - powers on but won’t power off by same button and….

Mon, 04 May 2026 11:21:32 -0700

Hi all,

Hoping for some help bit long shot I appreciate. My speakers not turning off by the button I can turn it on from so one assumes the button is ok?

The volume buttons do nothing and are unresponsive.

These issue existed before I dismantled it to replace the battery and was kinda hoping that may fix all the issues or at least re seating everything.

Any suggestions greatly appreciated,

For info this is an original wonderboom and it still plays music albeit quality is bit naff now. Will likely buy a replacement but I’m a stickler for trying to fix before scrapping anything.

Thank you!

Greg

Today my UE Wonderboom suddenly stopped working, however it will not power down. The power light blinks but it will not turn off, pair, or anything else. I tried the factory reset, and it will not work. Can anyone help, please? Thank you!

UE BOOM 2: Factory Reset won't work...

Sat, 08 Nov 2025 22:44:21 -0700

This is quoted from another post:

Factory rest [for UE Boom 2]

Note that doing this many times in a row may harm your speaker, so refrain from doing this more than once or twice.

What does this mean exactly? I have tried resetting my UE Boom 2 and now the Bluetooth Sync light won't stop flashing when I try to turn it on. And it won't display on any devices either. Is this speaker toast? Thanks.

Logitech UE MegaBoom: Can 18650 battery cells be replaced, or will circuit self-destruct?

Wed, 01 Oct 2025 04:37:24 -0700

Some manufacturers deliberately program the battery circuit to destroy itself if the battery cells were to be disconnected. They do that to have a monopoly on original batteries and rip consumers off.

Has anyone tried to replace the 18650 cells and had success?

For me it did not work, and I made no errors in replacing them. My box behaves as if no battery is connected (sometimes noisy sound telling me "critical battery" and such only while plugged into USB). I now wonder if the battery is actually the cause, though it seems so.

Logitech Bluetooth Speaker: Ultimate Ear Roll 2 not charging

UE Roll 2 doesn’t charge any more. I change the battery but still not charging: the light doesn’t flash. I barely hear a vague sound when I try to reset after 1 hour charging.

Is it really dead?

Logitech UE MegaBoom: Stuck in Demo Mode

Fri, 19 Sep 2025 08:47:12 -0700

I have a UE megaboom.

It is a “demo” model and hence has bluetooth disabled.

I have tried factory reset (Minus, and power button for 15 secs)

I have tried hard reset (Minus,Plus, pairing button for 15 secs)

When I try to update software with the UE speaker update assistant on windows, Windows cannot detect my device - “USB device not recognized”, and then the update assistant cannot proceed.

Logitech UE MegaBoom: Megaboom 3 cannot downgrade demo mode firmware (v31.0.11)

Thu, 28 Aug 2025 18:25:02 -0700

I just bought a used Megaboom 3 which on arrival turned out to be a demo unit. I have read lots now about the demo units only being different due to the firmware version which disables bluetooth and requires a permanent USB cable connected to work.

Other people have been successful with earlier versions of the speaker in downgrading the firmware to the proper user firmware, but the apps I have are not working for this so far. I have the current version of the update assistant from the UE website which tells me the Megaboom is up to date (and has no option to thus do anything else), and an older app UE_1.3.91_x86 which does not recognise the speaker when the USB cable is connected.

Is there another version of the update app that will work with the megaboom 3 specifically and allow me to downgrade it please?

I’d be incredibly grateful as I was hoping to give this as a present. Thanks

UE mini boom: Speaker has suddenly stopped connecting to all my devices.

Fri, 08 Aug 2025 11:28:29 -0700

I have connected to my phone, tablet and computer in the past with the UE Mini Boom without any issues, it has now stopped connecting to all devices. I have read that to solve this problem you hold the - volume down with the on/off button until it makes a sound and it should resolve, however my speaker has a slide across on/off button so I"m unable to perform this.

I have also run application to see if there are any updates required which there wasn't.

Cheers

Lynda
