I have a few different Linksys WRT54G routers and I've installed DD-WRT - build number 44715 - on them. However, this build appears to have been made in 2020. So, I was wondering if there's a more modern version of dd-wrt for this router. If not, is it possible for me to compile the latest version of OpenWRT for these routers which have 4 MB of flash and 16 MB of RAM?

I've found 2 vintage desktops from around the 2000's era. One already had a broken power supply that won't even turn on (and thankfully didn't break anything else). The other desktop had a working ATX PSU, but it just blew out a few days ago. The PSU is an Elitech LC-B450E and I believe it has 4 molex connectors.

Now, I was wondering, would it be possible to repair the PSU (not that I would do that myself because I don't even know how to solder)? If not, would it be possible to get a relatively new one that's compatible?

I was thinking of getting a wifi card like that, but can't seem to find any.

I am running Linux on my macbook pro and it has a Broadcom BCM4360 wifi card. Problem is that the driver for it is proprietary (or more accurately, mostly proprietary with some of the source code available), quite outdated, and I couldn’t get it to work with Linux kernel v6.9.5.

I am running Gentoo Linux on my macbook with a custom kernel. I previously had wifi working, but then I reinstalled Gentoo (because I wanted to do full disk encryption), copied over the kernel config file from my previous install (which I knew had working wifi), migrated it to a newer kernel version (plus added support for full disk encryption) and now the wifi drivers won’t even compile.

So, I was thinking of replacing the current wifi card with something that has modern and open-source drivers for it. Is it possible to do that on a Macbook pro 11,2 (Retina, 15-inch, Late 2013)? If so, are there any compatible wifi cards with open source drivers for Linux?

I want to install a (or build my own) custom AOSP-based OS on my Samsung Galaxy J3 SM-J337W that has microG instead of the proprietary Google Play Services. Please forgive me if I'm doing something stupid: I'm a complete noob with this.

So, the first thing I did was check and see if my device is officially supported by ROMs like LineageOS and I couldn't find anything. Not only that but my device isn't supported by TWRP.

Next, I've done a bit of further research and read about GSI ROMs and Project Treble. The Treble Info app says that my smartphone is Project Treble compatible with the following requirements:

• VNDK version: 28 (lite mode)
• System as Root: disabled
• Manifest location: Modern
• CPU architecture: ARM32
• Binder architecture: 64-bit However, the only a64 non-SaR GSI images that I could find are some of Andy Yan's builds of LineageOS 16 and 17 and they do not have microG installed. Plus, I just don't want to install any malware-infested OS from some random Joe.

I've been thinking of building my own custom ROM or GSI. However, compiling AOSP would take a long time.

Has anybody ever managed to install a custom OS on the Samsung Galaxy J3 SM-J337W?

I have a Samsung Galaxy J3 2018 (model number SM-J337W) on which I want to install my own custom AOSP ROM (because I don't want Google or Samsung to spy on me, I'm stuck with my current phone, and my phone is not supported by LineageOS, GrapheneOS, or CalyxOS). I have managed to install ADB for Linux and unlock the bootloader, but I can't download any TWRP binaries because my phone is not on the list of officially supported devices. I believe i've found the source code for TWRP on this Github page: https://github.com/minimal-manifest-twrp/platform_manifest_twrp_omni. However, I'm not really sure how to build it. According to the code lines bellow, I believe it requires some kind of device number or code:

cd <source-dir>; export ALLOW_MISSING_DEPENDENCIES=true; . build/envsetup.sh; lunch omni_<device>-eng; mka recoveryimage

or if I'm not using a recovery partition:

cd <source-dir>; export ALLOW_MISSING_DEPENDENCIES=true; . build/envsetup.sh; lunch omni_<device>-eng; mka bootimage

Also, I am not sure whether or not if my device uses a recovery partition or not. How do I find that out on my specific device?

Also, when I open up AIDA64, then go to System -> Device, it says j3topltecs. Should I use that for my device number/code?

Also, please keep in mind that this is my very first attempt at rooting any Android smartphone so sorry if I sound like an idiot noob. I also use Linux and don't have Windows installed.

Also, is there any way I could tell lunch (or whatever tool does the compiling) to use only a specific number of threads because if it starts compiling using all 8 threads then my PC will definitely overheat.

PS. Do I even really need TWRP? Has anyone ever managed to install a custom ROM on this specific device?
