What’s the best Xperia X10 custom ROM?

February 27, 2011 – 7:43 pm by Adnan Hodzic

Everybody hates Xperia

When I first got Sony Ericsson Xperia X10 it was running on Android Donut (1.6), my frustrations followed soon after mostly because it was greatly lagging with release of Android 2.1. Finally official 2.1 was released, but troubles didn’t stop there, because everybody was waiting for multi-touch support … I could go on like this for a very long time. However, to sum it up Sony has no plans of updating X10 anymore, they are releasing brand new phone (Arc) and they are hoping people will pay money to get it after X10 horrors. Even tho 2.1 isn’t that old, (31.4% of overall Android users is using it on it), Sony changed its UI to make it look better, but all they actually did is make it look pretty bad + made it abnormally slow.

Xperia ROMs

From hardware aspect, it’s a pretty awesome phone, but from software aspect it waste of nerves. It’s obvious that Sony needs to hire more Linux people, because as it seems they have no idea what they are doing.

There are of course, 2.2 Froyo and 2.3 Gingerbread “straight from Google” ROMs, but to be honest … phone is only half usable with those. The feeling I get when using these is … plain awkward. All these ROMs are stuck on 2.6.29, since as it seems Sony did a very good job protecting its bootloader, what I suggest is to use these for strictly development purposes, and have them dual boot with your “working” 2.1

2.2.1 Froyo (beta)

Gingerbread 2.3.1 (alpha)

So what is the best ROM?

Out of all the ones I tried (and I tried many) it’s definitely: kX10 Custom 2.1 SE ROM – R2B001

My main argument on what this is the best ROM is because, everything is working, and it’s working fast. Author stripped it to the minimum, and what I definitely suggest is that you go with the “R2B001 Lite” because the “Full” version comes with too much apps. with it, kinda making this great ROM feel bit bloated.

I made a video for you to “experience” its speed:


  • 2.1 Generic Firmware (2.1.A.0.435), Rooted with xRecovery, JIT v2, SuperUser, and busybox installed;
  • SuperCircle Battery / Reboot option mod;
  • Ubuntu system fonts with Emoji support (display only)
  • All APKs zipaligned / All non-essential system APKs moved to /data/app for easy uninstall and apps2sd support
build.prop Modifications
  • windowsmgr.max_events_per_sec=260 – Makes scrolling smoother
  • wifi.supplicant_scan_interval=180 – Slows down the WiFi scan to every 3 minutes, saves battery
  • dalvik.vm.heapsize=26m – Optimal heapsize for most X10s
  • mot.proximity.delay=100 – Makes the screen off/on proximity sensor more responsive

Surprisingly I’m getting much lower score Quadrant score, but also getting a much higher Linpack score: benchmark results of hacked Stock SE 2.1 ROM (2.0.2.A.0.24 root + JIT) Even though, the phone’s much much faster.

A couple of screenshots, including Linpack/Quadrant benchmark results.

Nexus S

This is how I’m planning to live my remaining days on this phone, if it wasn’t for this ROM, I would’ve crashed my X10 long time ago. In meantime I’m eagerly waiting to put my hands on Nexus S, whose official release we’re still waiting for in Europe Thinking

Google, please hurry up Smile

    It’s a pity the android development process is so arcane and opaque. The community seems to embrace that though.

    Frankly I wouldn’t trust any of these random custom firmwares in the same way I trust debian.

  • Stop whining. Get the iPhone already. http://www.youtube.com/watch?v=Aem4OlegHqg

    I’m surprised that you still feel comfortable posting online about Sony. Did you happen to miss that the company is waging a legal war against “hacking”?

    Granted, their lawyers are not currently targeting phones, but there is no reason to assume that their phone division will remain unaffected by their greed.

  • @robert, true, well you saw what’s Nokia doing with Meego Thinking

    @Gurkan, I’d rather buy any other phone then use iPhone. Please …

    @Arno, meh http://www.youtube.com/watch?v=drJWxMLrpE0 Smile

    Next time, vote with your wallet and avoid Sony at all cost Smile

    Happy HTC user here… when I saw Sony Ericsson shipping 1.6, it immediately raised a red flag. I also avoided Samsung for the same reason. (Well, that and the hardware being *way* too light for my taste. I really appreciate the technical feat, but it just doesn’t sit well in the hand.)

  • Trust me, I was Sony Ericsson customer for 10 years, after Xperia … never again. I adored its looks and was hoping it’ll get hacked eventually and you’ll be able to use any ROM out there … I was very wrong Big Frown

    I too avoided Samsung until Nexus S was released, now that’s all I really want, even though its camera is 5MP (xperia 8mp), and it’s missing LED light unlike xperia and many others. But in order to have the latest Android out there, and that’s all I really care about.

    Still waiting for it to appear in Europe IDK

    Next time don’t call them ROMs. They are operating system images for fucks sake. Software NOT firmware.

  • MysticMaverick

    Read on – Sony have pledged to bring 2.3 to our X10 mobile, now theres a turnaround Smile

  • I know, didn’t expect that one, don’t care tho since I got myself Nexus S Smile

  • MIUI for xperiax10

    Thank you for sharing. My Trip rom (MIUI based) has a Quadrant Score of 1250 to 1379 and Linpack 35 MFLOPS score though. And, best of all, the interface is so much better than standard Android (white background, black texts for all menu settings). Check it out on Modaco: 

    Best regards

  • Mc3ain

    I know this is an old thread, but, i thought if anyone new is looking into this i would recommend this rom over at XDA  http://forum.xda-developers.com/showthread.php?t=1307044

    it works on locked and unlock bootloaders, and im getting quadrant scores between 1200 and 1400 with a slight overclock. and linpack scores around 39-44
