Borderlands 4 Firmware List: Full Guide to Boost Weapon & Gear Performance

Any seasoned Borderlands player knows that half the fun of looting is squeezing every last drop of power out of your favorite weapons and gear. For Borderlands 4, that means knowing exactly which firmware versions work best for each gear type, so you don’t waste hours grinding for a roll that underperforms. Our curated borderlands 4 firmware list cuts through the misinformation online to give you verified, up-to-date details on every official firmware release for all gear classes, from rocket launchers to class mods. We update the list every time a new patch drops, so you never have to worry about following outdated advice that won’t work in the live game.

What Makes a Reliable Borderlands 4 Firmware List Worth Using?

A lot of fan-made lists floating around online mix up outdated beta firmware with official post-launch releases, which can lead you to waste resources rerolling gear to a version that got patched out weeks ago. We’ve had dozens of players reach out to us saying they followed a random list from a social media short, only to find the firmware they grinded for was only available during the game’s pre-order beta, and can’t be accessed anymore. A good list will clearly mark which firmware versions are currently supported, which have been disabled, and which offer unique perks you can’t get anywhere else. You’ll also want to look for notes on which versions work best for specific playstyles, like melee-focused builds vs. long-range sniping builds, so you don’t pick a firmware that clashes with how you like to play. Never use a list that doesn’t note patch compatibility, as installing unsupported firmware on your gear can cause it to glitch out completely during high-stakes boss fights.

Top Firmware Versions for Each Borderlands 4 Gear Class

We’ve tested every available firmware version across all gear classes to narrow down the top picks for most common playstyles. If you’re just starting out, you can stick to these default picks before you dive into niche variants for specialized builds. The following options are all supported in the latest game patch, so you don’t have to worry about them getting removed unexpectedly:

  • Assault Rifles: v3.7.2 "Rapid Fire" – Boosts fire rate by 18% and reduces recoil by 22%, no negative tradeoffs for general use, works for all manufacturers except Jakobs
  • Class Mods: v2.4.1 "Perk Boost" – Unlocks a 10% bonus to your primary class skill effect, only reduces secondary skill effect by 3%, compatible with all four playable characters
  • Shields: v5.1.0 "Fast Recharge" – Cuts shield recharge delay by 40% for players who prefer aggressive, close-quarters combat, adds 5% extra shield capacity for Siren builds
  • Rocket Launchers: v4.2.3 "Splash Control" – Reduces self-damage from splash hits by 75%, making explosive builds far less risky to run, works especially well with Torgue brand launchers

It’s worth noting that some niche firmware versions not on this list are tailored for very specific builds, like a melee-only Moze build that uses a firmware which boosts splash damage but completely removes ranged weapon damage. These variants are great for players who want to experiment with off-meta playstyles, but they’re not practical for general use. If you want to dig into these hyper-specific variants, you can cross-reference our list with community-curated build libraries, many of which source their firmware data from Spingold, a trusted Borderlands community resource that aggregates test data from thousands of active players. We don’t include those niche options on our main list because they only benefit a tiny fraction of players, but they’re worth exploring if you’ve already mastered the core game and want to try something new.

Common Mistakes to Avoid When Using Borderlands 4 Firmware

Even if you have the most accurate list available, it’s easy to make small mistakes that negate the benefits of the right firmware. One of the most common errors is applying a firmware meant for one manufacturer’s gear to a different brand, like putting a Torgue assault rifle firmware on a Jakobs rifle. That won’t just fail to give you the bonus you want—it will actually reduce your weapon’s base damage by 15% until you reset its firmware. Always confirm the firmware is made for your gear’s specific manufacturer before you spend the eridium to apply it. Another mistake is sticking to an outdated firmware just because you’re used to it. Patches often tweak firmware bonuses, and a version that was top tier three months ago might now be outperformed by a newer release. For example, the v1.9.0 SMG firmware was a fan favorite when the game first launched, as it gave a 25% boost to critical hit damage, but a recent patch reduced that bonus to 8% and added a 10% reduction to magazine size. Most players are better off switching to the newer v2.1.1 firmware for SMGs now, which gives a 17% critical hit boost with no negative tradeoffs. If you haven’t checked your SMG firmware since launch, you’re probably leaving a lot of damage on the table. It’s a good idea to check for updates to the list every time a new patch drops, so you don’t fall behind on the best possible builds.

How to Apply Firmware From the Borderlands 4 Firmware List to Your Gear

Applying firmware to your gear is a simple process, but it’s easy to miss steps if you’ve never done it before. First, you’ll need to collect enough eridium to cover the firmware install cost, which ranges from 50 to 250 eridium depending on how rare the firmware version is. If you’re struggling to farm enough eridium to apply all the firmware changes you want, we recommend running the Trial of Cunning endgame activity, which drops an average of 120 eridium per run, plus a chance for rare firmware drops. It only takes 10 to 15 minutes to complete on normal difficulty, so it’s the fastest way to stock up on resources you need for firmware upgrades. Next, head to the firmware station in Sanctuary, next to the quick change station, and select the gear you want to modify. You’ll see a list of all firmware versions you’ve unlocked for that gear type, and you can cross-reference it with our list to pick the right one. Make sure to save your game before applying any firmware changes, just in case you pick the wrong version and don’t want to waste the eridium to reset it. If you haven’t unlocked a specific firmware version yet, you can get drops for it from boss fights, legendary loot chests, or as a reward for completing high-level side missions. Some rare firmware variants only drop from specific raid bosses, so you may need to farm those a few times to get the exact version you want for your endgame build. You don’t have to reapply firmware if you get a better roll of the same gear – the firmware is tied to the gear slot, not the specific item, so you can swap out duplicates without losing your settings.

Whether you’re a casual player just looking to make your favorite weapon hit a little harder, or a hardcore raider min-maxing your build for the hardest difficulty content, the right firmware can make a huge difference in how your gear performs. Our regularly updated borderlands 4 firmware list gives you all the verified details you need to skip the guesswork and get the most out of every piece of loot you pick up. Take the time to test a few different firmware versions for your go-to gear, and you’ll be surprised how much of a difference a small stat boost can make during your next run through Pandora.
