Android Open Kang Project (AOKP), one of the fastest-growing family of custom ROMs out there. The project has released over 30 builds since its inception late last year, and is now on Milestone 5. This doesn't mean much beyond the fact that they've reached a point where enough new features have been added to justify upgrading for those who don't flash nightlies as a habit. You can see the release notes and downloads for dozens of devices here.
Xperia S now has CM9 (Ice Cream Sandwich) and ClockworkMod recovery courtesy of the clever devs over at XDA. If you're feeling adventurous and you know your way around a bootloader, give both of them a try.
DROID RAZR and DROID RAZR MAXX are downright handy if you're looking to maximize your phone's longevity. Unfortunately, those two phones (and their international counterparts) are the only ones that get the privilege. But with some modding and a little elbow grease, Twitter user Dan Davis managed to modify the app so that it runs on the DROID Bionic as well.
XDA member Deeco7 has posted a modified version of the "Vending.apk" Google Play Store app file, with the aim of allowing anyone to download any app, regardless of their own location or the restrictions built into the app. The modified app works with Android 2.2 or later, and you don't even need root to install it.
Motorola DROID RAZR launch announcement was the fact that despite Moto's commitment to more open bootloaders, the flagship phone would be locked down just like previous Motorola-Verizon devices. Even after considerable customer backlash and unlocking the bootloader on the international GSM RAZR, not to mention the fact that both Samsung and HTC have provided unlocked bootloaders for their own Verizon phones, Motorola has stood frustratingly firm. Now a pair of modders have found away around the locked bootloader, opening up the possibility for true custom ROMs.
HTC One X is pretty great, but its 1800mAh battery (not unlike the one on the Galaxy Nexus) is only OK. It turns out that HTC itself made something of an error in judgement when putting together that shiny new software. Due to an errant APK location, the native NVIDIA power control app (you know, the thing that makes that magical "5th core" work to save all that battery life) wasn't working properly. HTC should have a fix out soon enough, but in the meantime, the fellows at XDA have a fix for you.
AT&T's Pantech Element tablet just today and immediately installed ClockworkMod recovery to, as it were, boot. The process is fairly simple as root goes: connect the tablet to your computer with ADB enabled, get into the fastboot interface, send over a custom image, then download a SuperUser app and you're done. Check out the original thread for more precise instructions.
light and pro versions of the Radioactivity Counter app. Yes, this really works.
Android Open Kang Project, more colloquially known as AOKP. The much-anticipated Build 30 of the custom Ice Cream Sandwich ROM is available for download now, complete with custom app shortcuts in the navigation bar for Galaxy Nexus users. There are also stable builds for the Samsung Nexus S, Nexus S 4G, Galaxy S, Galaxy Tab 10.1 and 8.9, the HTC Sensation, EVO 4G, Incredible and Incredible 2, the Motorola XOOM, the ASUS Eee Pad Transformer TF101, the Acer IConia Tab A500, and the HP TouchPad. AOKP is also, without a doubt, the best pink unicorn-themed ROM available.
Nook Color and Nook Tablet get the most attention out of Barnes & Noble's e-reader line, at least from an Android modder standpoint, but many forget that all of the Nook devices run Android - and all have been thoroughly modded. Even the humble Nook Touch has been thoroughly rooted with custom apps and ROMs, though the e-ink reader's hardware limitation prevents some of the more basic Android tasks from being completed. One of those can be disregarded now: XDA members wheiltijohnny and Mani100 have devised some custom code that enables multi-touch gestures for the diminutive e-ink reader.
