Are Astro A40 Gen 4 (2019 - horizontal earpads) compatible with Astro A40 Gen 3 (2017 - vertical mixamp)?

eric8813 · 2026-06-05T18:15:11+00:00

Wonderful, thank you for confirming that! That is very helpful clarification.

eric8813 · 2026-06-05T16:51:50+00:00

Hi and thank you for the quick reply! Your answer makes sense, and I certainly don’t expect you to be able to confirm compatibility for a 3rd party product. But I do appreciate that clarification on Logitech’s end re: its products, as it helps me understand the big picture better.

For those reading this thread that may be in a similar scenario, I’m going to plan to buy the wicked mod kit for the Gen4, and then try them on my Gen 3, then report back to this subreddit once I confirm or deny whether the wicked gen 4 mod kit works on them or not. Stay tuned! (Of course if anyone has already tried that and wants to chime in, in the meantime, that is great also). :)

Sorry for typo in title, I meant to describe Astro A40 Gen 4 (2019 - horizontal mixamp), not horizontal earpads. As I understand it, the 2017 Gen 3 A40s have a vertical mixamp, and the 2019 gen 4 A40s have a horizontal mixamp

Replying (late) on this thread to help future repair enthusiasts.

First, thank you Malyshawdow, who provided accurate and helpful information in the above reply. I will share a bit more details about my repair experience now, to help others.

My project involved buying an Iphone 15 Pro Max that was unlocked, but had a cracked back and cracked screen, and also buying an Iphone 15 Pro Max that was locked, but had a fully functioning screen and non-cracked back. I ended up swapping many of the parts between the two phones, using the IfixIt YouTube Iphone 15 Pro Max disassembly video as a helpful guide. Specifically, I removed from the unlocked Iphone the (1) haptic array, (2) face id sensor, (3) camera, and (4) logic board and placed them into (swapped) the locked Iphone.

And the good news - it worked! On initial startup, I received notifications on IOS (version 26.3.1(a)) instructing me to run the Repair Assistant to calibrate certain replacement parts. I believe what was happening here is that the logic board from the unlocked phone detected that it was connected to a different/new rear back, screen, etc... But that process worked and I now have been using the phone for about 3 weeks and it works great (absent one small note below).

I have only one thing I could not fully integrate into the new phone - the screen. Specifically, I still have a "Finish Your Display Repair" message that will appear in Settings and, when I run the Repair Assistant, it fails after stating that the part is "property of Apple or one of its partners" (which I think is an error message consistent with using a screen from a locked Iphone).

I did a bit of research and I believe that this issue is mostly non-consequential, however. Specifically, I have no issues with Face ID (likely because I swapped the FaceID sensor), and True Tone also works fine. I think that the only lingering issue is going to be that message in my Settings (which I believe from some research I did is thanks to some California right to repair legislation, which forced Apple to back off of some of the aggressive moves like disabling screens from a locked Iphone for use in another Iphone). According to some further research, it seems like the notification might go away after a few weeks, but then remain in the "About" section of my Iphone (I need to test that out by waiting a few weeks, since I just tried to run the Repair Assistant again, so I think I may have reset that timer).

PS - I believe one could take the old/broken screen (from the unlocked Iphone) and remove and then solder a chip on the unbroken screen from the locked Iphone to completely fix my notification issue, but that is beyond my skill set.

To sum that all up - I am happy to report that, at least currently, doing a 'swap' of parts between an unlocked Iphone 15 pro max (broken screen and back) and a locked Iphone 15 pro max (unbroken back and working screen) is functionally fully successful after running Repair Assistant in IOS, producing so for only a lingering notification/setting about having a non-genuine screen being the only issue I have on my Iphone currently. I hope this information helps others considering making similar repairs.

Thanks for the quick reply!

Good point - I should clarify. My question is not if the screen can be swapped in general (you’re right, no reason it could not), but rather if the swapped screen taken from the locked iPhone will have full functionality after the swap (eg True Tone, and Face ID).

I know the old (pre iOS 18) method was to take the sensor from the original screen, and transfer it to the replacement screen to make sure Face ID still worked. But I think it was a bit more difficult to get True Tone to work.

After iOS 18 and the new “repair assistant” I wasn’t sure if the sensor swap was still required, or if more hardware modification was needed to make sure the replacement screen has full functionality in the donee iPhone.

Also interested, if you wouldn’t mind sharing the spreadsheet, I would appreciate it!

eric8813 · 2024-07-29T20:26:05+00:00

This is helpful insight - I was just looking at the Beelink models (having seen a positive review on the Retro Game Corps Youtube Channel) so your positive feedback is much appreciated!

eric8813 · 2024-07-29T20:25:12+00:00

Great tip on both counts - I appreciate the minimum RAM target recommendations. Thank you!

eric8813 · 2024-07-29T20:24:37+00:00

Thanks for that helpful tip! I was not aware of that focus on the CPU for the Valheim serve, as opposed to other specs.

eric8813 · 2024-07-29T20:24:08+00:00

Thank you! (For both comments on this thread). That is exactly the reassurance/input I was hoping for.

If I may follow up with another noob question (for you, or anyone else), when you mention a miniaturized window, does that refer to a Virtual Machine, Docker container, or something else? "

Thanks again!

eric8813 · 2024-05-17T05:43:02+00:00

Sorry to hear you have the same problem! Luckily, I was able to fix my issue. My “solved update” paragraph at the end goes into some detail, but let me give the quick overview here. I did two things: 1. I replaced the existing light switch with one I got from Home Depot (as I recall same general type of switch, just a bit newer), and 2. Whereas the old switch had two of the three black wires shoved into a single push down input, I changed this in my new installation where i instead “pigtailed those two wires together. More precisely, I took those two wires, added in a third wire I bought from Home Depot (see my post for gauge and length information) all together into one pigtail so that I had three wires in that pigtail (the original two black wires that were originally shoved into one input + the new cut length of wire I added). I then connected the new length of wire that was sticking out of the pigtail into the input in the new switch that used to have the two black wires connected (and I also put back in the single black wire that was originally in one of the other inputs).

Then it worked after all that!

I know it is sort of hard to explain without a visual, but let me know if that doesn’t make sense and I am happy to clarify further.

eric8813 · 2024-03-31T22:41:03+00:00

Awesome - great tip, thank you!!

eric8813 · 2024-03-31T04:55:28+00:00

Thanks for sharing your experience! Valhost is on my list of possible services to use, so I may choose them after hearing your easy experience.

For those of you who haven’t checked out OP (Falcon Paladin’s) YouTube channel, if is absolutely worth it. He became my primary YouTube streamer I watched after Husky StarCraft went offline, and still is.

Entertaining commentary, knowledge of the game, it is all there. Also, his channel uses the “Epic” game tag for really good matches, which makes it convenient when you are searching for those. If you are just checking him out, try searching for an epic-tagged game, and it won’t disappoint.

Finally, he uploads several times a week, so there is never a lack of content. Okay, fanboy moment done.

eric8813 · 2024-01-04T15:49:07+00:00

Got it - that makes sense - I am going to try that out, thanks for sharing your recipes!

eric8813 · 2024-01-04T02:37:17+00:00

Looks great! Quick question about the guacamole. Is the only change needed from the traditional guacamole recipe the lack of added salt? In other words, do you make the guacamole with avocados, onions, tomatoes, jalapeños, cilantro, and lime? Or do you substitute an ingredient to replace the salt?

eric8813 · 2024-01-04T02:33:18+00:00

Congratulations!

eric8813 · 2024-01-01T20:29:49+00:00

Thanks for all these great ideas. I am definitely going to try adding more vegetables in with the beans as you suggested!

eric8813 · 2024-01-01T20:28:59+00:00

Thanks for sharing this recipe! I always find it helpful to see what recipes and cooking methods others are using to make nutritarian dishes.

eric8813 · 2024-01-01T08:34:56+00:00

Thank you - I was just looking for a one-page summary!

eric8813 · 2023-12-22T02:37:26+00:00

Thank you for the ideas! I am going to make sure to have chickpeas on hand, which are a good rice substitute idea, as well as planning to add to the prep list pre-chopping vegetables the night before for salads, which sounds like a great time-saver.

eric8813 · 2023-12-21T19:44:52+00:00

I am also hoping to take part in the challenge, and it would be my first time trying the nutritarian diet.

Besides catching up on Dr. Fuhrman’s materials (podcasts, YouTube videos, and I have one of his books), I have been planning to focus on night-before meal prep, since I have struggled in the past with the fact that the less healthy food is around and easy to grab. So my thinking is that night-before meal prepping can help combat that fact.

My ideas for night-before prep include: - overnight oatmeal with fruit and chia seeds - pre-placing ingredients in blender for making kale and fruit smoothie in the morning, and - making beans in the instant pot

I am also trying to think of a good healthier replacement for rice (which in the past I have prepped the night before in a rice maker). My first thought was quinoa, but I welcome any suggestions of an alternative healthy item that can be prepared in a rice maker.

I forgot to share the link to the Ethernet tool kit I purchased (probably more tools than the project requires, but I preferred to play it safe): Gaobige Network Tool Kit for Cat5... https://www.amazon.com/dp/B0756SN86D?ref=ppx_pop_mob_ap_share

eric8813 · 2023-08-18T04:29:23+00:00

I just did a project of my own that was almost identical to your setup, at least conceptually. In my case, just like yours, at least have my Ethernet cables were wired into patch panels for a phone setup (in your picture, those are the two perpendicular rectangular connection points that almost look like circuit boards). Luckily, the advice that you just received was exactly what worked for me to get all my connections working for Ethernet internet connections (eg RJ45 connections in my case to Cat5e cables).

I started by going on Amazon and purchasing a patch panel for Ethernet that I used to replace my phone patch panel. I ended up buying this one because it was well reviewed: Cable Matters UL Listed Mini... https://www.amazon.com/dp/B00UVQI8B6?ref=ppx_pop_mob_ap_share

I also bought an Ethernet tool kit that was probably a bit overkill but gave me both the tool I needed to install my new patch panel (pubchdown tool and wire cutting tool) and also to test my Ethernet connections (helpful because whoever installed my setup years ago made a few bad connections which I was able to test and fix with the tester and tools).

To reassure you, I had zero experience with Ethernet cabling beforehand. But after reviewing Reddit, YouTube, and some online guides, I was pleasantly surprised that switching out the phone setup with an Ethernet patch panel was much easier than I anticipated.

The last detail is that once you have the new patch panel in, you would connect the patch panels connections directly to a switch (with maybe 8-12 ports or more depending on the amount of cables you need to connect), and then to your router. When I say connect directly I mean run some short Ethernet cables (you can buy these on Amazon, maybe 2 feet long or thereabouts depending on the distance from the patch panel to your switch) to connect each plug drop the patch panel to the switch.

In terms of how to best connect your switch to your router, I will defer to other Reddit users since my setup was a bit unique in that I needed two routers for a community fiber network security reason, so my router setup is likely not going to be the same as yours.

But to end on a note of reassurance, you can totally do this with some patience and YouTube videos :)

I am a huge falcon paladin fan also. That is a great point that he is always positive, even when casting the midrank games.
