[HTC One X] gorle:
If you take a look at the Development Thread for the One X, you'll sure get confused by all the AOSP Roms you can find there (I'm also really confused). So I started this discussion Thread to compare this roms and help people finding the best AOSP Rom for the One X ;)

We have 9 AOSP Roms, I have personally tried many of these, but I really need the help of the community for the reviews of the Roms

But first... Why install a AOSP Rom? I love AOSP Roms because they are very simple, clean, user-friendly and really performance. You can download and apply many themes, tweak your device and give it your personal print!. With Sense roms my Internal memory was fast full even if I didn't put in it my files, I don't know why, but my Sense Rom filled my SDcard... BUT AOSP Roms have many bugs, like stock camera, WiFi direct (read the whole thread), and you can't use Beats Audio, because AOSP can't read Beats libraries (if I understand...)

So, let's start!

-Interpresentation's CM9 NIGHTLY UPDATED!!

CyanogenMod 9 Development

It's a every-nightly updated Rom, it's the basic CM9 with only a few issues, great Rom, hope you enjoy it!

User Reviews

"The focus of this Rom is to get a complete CM9 tree set up for One X, the others have extras, but this one is the simple nightly CM9 with great battery life and performances"

Issues

-Camera focusing on face

-Data Connection occasionally fails

Battery Test

1day and a half (user datas)

-Tbalden's CyanogenMod 9 Alpha 11 UPDATED!!

CyanogenMod 9 Alpha 11

This last, but not least CM9 Rom is one of the most preferred AOSP build, thanks to the stability and the less number of bugs you can find in. This Alpha 3 update brings LINARO optimizations (hope it works well and truly optimizes our phone), it should have fixed echo issues but it has to be tested... The Alpha 4 fixed a BT issue and added a few tweaks and the leasts updates fixed GPS, orientation sensors and LED notifications. I can't follow each update, it's daily :D, but here you have the changelog, the Rom is great, everything is working, stock camera, start working on MHL, Rom updated with new CM9 changes!!!

After a long development period (a week) tbalden came with an other alpha update (10th) that gaves a high-stability to your CM9. I'm using it for a whole day, battery is great and I haven't encountered any single bug... Great!!!

BLACK SCREEN ROTATION FIXED in Alpha11!!!!!

"Faster, smoother and more responsitive build"

Issues

-Face Focus

Battery Test

Personally tested, I use my phone a lot and it lasts me a whole day, so I'm really happy with battery!

Floatshow's PARANOIDANDROID [RC3] UPDATED!!

PARANOIDANDROID EndeavorU[ICS 4.0.4][HYBRID][STABLE]

If you had a SGS, GNEX, GNOTE, S2, Desire, Sensation and many others, you probably know about this great Rom (Official Site). It has the PAD and PAL (Per-App-Density and Per-App-Layout) that make this Rom not just a Tablet mode, that shrinks the dimensions of the apps and LCD density, but with PAL, this Rom changes tha apps layout, they really look like tablet apps: this is the first (and unique) Hybrid Rom, and it runs great!!!

The RC3 update brings alpha10 fixes and ParanoidAndroid 1.5 improvements!

User Reviews

-TripNRaVeR's CM9

CyanogenMod 9 - Endeavor Unleashed 017

You maybe don't like him, but he's a great developer that has solved the in-call volume issue, we have to be proud of him

He has built CM9 for months, with a huge changelog that's making his rom quite perfect, this new update made the touchscreen more responsibility. Trip is developing a 3.1.10 kernel, we all have to thanks him because many features are fully wotking, you can find the kernel here

User Reviews

"Freaking fast, best Rom for my One X"

Here a complete review with battery stats!

Issues

-Face Focus

Battery Test

Battery drains a full charger in 7-12 hours with heavy use. If you keep your screen off, it will last much longer

-Owain94's CM9 Domination Build7 UPDATED!!

Domination - Taking Cyanogenmod to the next level

This is one of the two Roms I've flashed on my One X, but I didn't like it at all, battery is not good but we have many many tweaks to use:

Custom density, kill button in recent apps, tablet mode, NEON codecs, font changer and many more... The update increses the phone performances and the gives you a really smooth device. This new update (Build5) improves performances, adds tweaks and drain less battery! Build 6 fixes everything, from random reboots, to a2dp and MHL support! The build 7 update fixes black screen rotation but there is a multitouch bug that will be fixes soon. Check the HUGE changelog here

Issues

-Camera FCing, use third-party cameras, they work ;)

Battery Test

Not Good (don't have numeric datas)

-Krarvind's Slim ICS 4.0.4

Slim ICS (OneX) - Clean, Simple & Fast

And this is the second one I've tried and I REALLY like it: battery is great, i think because we have a lot of free RAM (1.1 GB free of space in system!). It's fully customizable because it has AOKP settings, only 100MB to download. This 4.1 update brings performance improvements, many fixes and WiFi Direct and a2dp working!!! Try it because kravind made a really impressive Rom! New updated file with a single zip to flash (that includes basic rom, essencials and slim gapps). Official Site Here

Issues

-Camera FCing when focusing and recording long videos (in 720p and 1080p)

-Wifi Hotspot

Battery Test

Great, 2 days normal using (don't have numeric datas)

-Nzvbjr's Unofficial AOKP HTC One X [Build5][b40]

[Beta4][b39]Unofficial AOKP HTC One X

This is the first but the less flashed AOSP Rom I think :o, but the developer has fixed most of te bugs, i hope people will try it.

With this new update the developer made a very fast AOPK, he fixed Hotspot, only stock camera FCs, you have to use Third-party cameras

I personally try it, it's a good Rom but after signing in in Play Store, I couldn't download many apps, they were incompatibles, but I used them in other Roms before.

With this new update this AOKP come out from beta version and becomes build 1, every bug is fixed if you don't care about the 0.5s blackscreen in rotation ;). But the dev made a bad work in this new update (build5), battery is more than terrible and instead of many improvements, like DSP manager and CM7 settings, the Rom is not as smooth as before the update, and GPS in very slow, hope the dev will check these soon...

Issues

-GPS is not perfect

-Camera FC

-In-call Volume

Battery Test

Battery is terrible, draind a lot with display OFF and much more with display ON...

-The|gamer's AOKP

AOKP (Build IMM76I)

Compiled with Trup's Tree, this is a great AOPK port, I haven't flashed yet, so I hope you guys help me reviewing this build

User Reviews

Adwinp's Sakura no Hik@Ri

[AOSP][BAREBONES] Sakura no Hik@Ri

This is not a CM9, neither a AOKP, it's only a AOSP/Vanilla Rom, I didn't try it but users say that it's faster than others AOSP Roms and stable, no FCs or crashes during tests. I hope you try it, it's a very promising Rom ;). In this Rom you can't find any third-party app, it's clean, you have to install them by your own

Issues

-Wifi Direct

-Wifi Hotspot (working on it)
