MeanROM’s is a replacement ROM for the HTC EVO 4G LTE which has three stated goals: being clean, mean, and nice. We’ve previously covered MeanROM for the HTC EVO 3D, which was one of my favorite daily drivers for a long time, but it’s become something of a new beast on the new phone.

The “clean” portion of the stated goals are that MeanROM looks like stock, not a lot of font nuttiness or jaggy themes going on. There’s really not much difference between stock and MeanROM’s looks when you first flash the ROM. There’s a slightly different dock, but nothing you can’t modify yourself back to stock.

The “mean” portion is aggressive tweaks for battery conservation while the screen is off, and dual-core mods for while the phone is on and running that keep the LTE ready as can be along with the ability to overclock to 1.72GHz. It also feels like there’s something been done to the multi-tasking memory management as once the ROM is booted everything runs pretty smoothly.

The “nice” goal involves adding things that are not part of stock or fixing problems that shipped with stock. Google Wallet works on this ROM, you have an accurate 1X/3G indicator of signal strength, a 5-in-1 power menu has been added, quick settings, HTML in Microsoft Exchange email, uncompressed MMS, MMS over WiFi, quiet camera, camera photo enhancements, long press volume rocker to skip tracks, capacitive buttons dim with the screen, 360 Rosie if you want it, smooth scrolling mods, circular battery with 1% increments, and a pack of both the 4G LTE and 3D ringtones, and a lot more.

After running this about a day, it’s made my phone a much happier EVO. I haven’t bothered with the overclocking or the flashable mods that ship with it because what ships just works great right out of the box. Most of the annoyances I have with the stock EVO 4G LTE were wiped away with one flash.

It scores in the 5000-5200 Quadrant range right out of the box, so there’s perhaps a little improvement without even adding the overclocking tweaks. The smoothness of the ROM is where this thing shines though. No long delays switching between things, no jerkiness.

The thing about MeanROM is that this is what should have shipped – working Wallet, smooth, perhaps not with the root tools, but you get my point.

Remember if you’re flashing this, make sure to clear your wallet settings if you managed to get a wallet set up beforehand. If you remembered mid-flash that you didn’t do this, don’t freak out, try opening Titanium and restoring the Android ID. Also make a nandroid backup as this is going to replace everything and if you don’t like you can flash back.
