[HTC One X] Whello:
FAQ for new readers of this thread:

Dear fellow XDA-user / One X owner. You might've stumbled upon this thread and not feel like you want to read all the pages here. I understand and that's why I've written a short summary of my own personal experience as well as the experiences of different users, using the particular ROM. This might answer most of your questions and if it's not in here, please feel free to ask.

In short, this is THE best ROM around for the HTC One X, built by one of the best and most devoted Dev's, Trip. Not only is it STOCK CM9 ANDROID 4.04, lightning fast and super buttery smooth but it's also quite stable and most core functionality works without a hitch! It is well suited for day to day use and I'm sure it won't disappoint. Please take your time browsing the various options and settings, there are so many to choose from! I personally can't go back to SENSE after using this ROM, despite its share of glitches. Let me explain;

* The camera app works but still experiences a few force closes, however you will still be able to take pictures and the flash etc. works. The extra options like scenes etc will work most of the time too, sometimes it will give you a FC. The videocamera functionality still seems to be very buggy, if you record video for about a minute and then decide to stop recording, the camera will FC on you 99% of the time. Most of the time however, the video recorded will still be usable or accessible in the Gallery app.

* The screen rotation works and it works very well, except for the fact that the screens blacks out for halve a second. However, I personally don't take issue with that :P. I'd much rather have a perfectly fluent UI than some transition that I will see rarely anyways. Besides, that halve second won't really bother you in getting stuff done, will it?

* Sometimes you have to tap twice or even three times on the END button to end a call, which can be a bit annoying. But it works eventually and thats better than not working at all, right? I'm sure it'll be fixed eventually. ;)

* Battery Life seems to be a bit short but okay, I am quite the heavy user and my battery life seems to go between 7 and 12 hours a day. That includes taking a few pics, around 20 to 30 a day, approx. 1 to 1,5 hours of incoming and outgoing phonecalls and about 200+ texts and whatsapp messages, approx. 10 minutes of Google Maps and approx. 30 minutes of Facebook and Twitter use. I use WiFi for like 75% of the day and have "okay" HSPA+ reception. Check out the Screenshot. It might be wise to use an app like Easy Battery Saver.

* Recharging the battery has seemed improved over a little while ago, it seems the battery recharge from zero to 100% is around 2,5 hours, if you leave the device untouched and on during the charging cycle. If you choose to use the device, the time to charge might increase extensively. Please note that when on the charger, it's not wise to use CPU or GPU intensive programs, the phone might overheat and shut down till it's cooled down. ***Please also note that the phone won't be able to enter deepsleep while plugged into a charger. This is a security and safety measure, Lithium-Polymer batteries must be in active use at all times and must not be overcharged, so the active processor generates activity and uses battery so leaving the phone on the charger while it's charged to full, won't damage the battery or pose physically harmful risks like exploding batteries. I must urge you not to try and change that, it will seriously damage the battery and might cause physical harm to you or others in the vincinity of the phone while it explodes or bursts out in flames!*** (Example: http://www.youtube.com/watch?v=C5_-eBbDE0s)

* Sometimes, once or twice a day, the phone decides to do a hot reboot all by itself, so no HTC logo, just the CyanogenMod animation and then you're welcomed back to the lockscreen, where after like 10 seconds or so, the phone just freezes and it starts a complete reboot, where it starts where normal reboots start, at the HTC logo. After the second one (the complete reboot), it works perfectly again (???). I'm fairly sure it's not any app or anything I use, it's just really sporadic and you won't be bothered by it much but it might be a word of caution. Why? Please check your phone atleast once every hour, if it did a reboot in your pocket, chances are you won't be receiving calls or texts or anything while on the go, because it requires your SIM pincode. Again, doesn't happen very often, but it does happen.

* Wifi and Cell reception indicators seem to work perfectly fine now, haven't been able to notice any faults there. In previous builds, there have been problems with the indicators, they might have a few issues where the indicators might not have worked or showed a no signal where the user would still be able to make full use of the device. You might want to flash your phone to the latest radio, it improves signal and call quality quite a bit ;): http://xdaforums.com/attachment.php?attachmentid=1130356&d=1339710628

* LED indicators work perfectly fine. Please note that the LED will turn green when getting to 90% charged. This is not a bug but a safety measure implemented by HTC by default. For when by some freak accident the phone does enter deepsleep while charging. When you hit 100%, it might just be best to disconnect the phone from the outlet and just go to bed. If correct, it won't use more than a few percent during the night.

* Bluetooth and hotspot problems seem to persist. However, I haven't tried this functionality personally, I will try it sometime soon and update this post where applicable :). The Bluetooth issues seem to be related to the provided music player. It might well be that the problem won't show when using a different player. Good hunting ;).

* The provided Apollo music player can be quite the nightmare and FC's in a heartbeat. Might I suggest you download Winamp? Also, when the screen goes off, you might encounter weird bug where your music starts playing in slow motion, if so, set the CPU-governor to interactive. The problem should no longer be present after that.

The very best music player I've used on this device is PowerAmp Music player. Awesome app but sadly not free :(. If you have the money, buy it, it's just awesome.

* The provided G-Apps and Boot.img work fine, use the ones Trip provided, if they don't work fine, please let us know and I'm sure Trip will conjure something up in a day or two :).

Please use the following guide when coming from a different ROM:

- Unlock Bootloader @ HTCDEV.COM.

- Download and Install CWM Recovery and place the downloaded ROM.zip and G-Apps.zip on your SD card.

- Download and use Fastboot to install the new Boot, using the following command: ./Fastboot flash boot boot.img

- Use Fastboot to erase the cache memory on your device and go back to Hboot. ./Fastboot erase cache

- Boot into CWM Recovery and format Cache, Data, System and Dalvik cache. All except for the SD Card obviously. ;)

- Then use CWM Recovery to first flash the ROM.zip and then the G-Apps.zip.

- After succesful installation, reboot the phone and if done correctly, you will have a working phone :).

- If you haven't followed these steps precisely or perhaps skipped a step, please try these steps again and don't spam for help.

- If you have and after a second or third try it still doesn't work, please, by all means, let us know and we will try to help you out!

If you already have Trips ROM on your phone, you can skip a few steps and just do the following:

- Use fastboot to erase cache.

- Flash the latest boot.img provided with the ROM.

- Flash the ROM and G-Apps both provided by Trip.

- Reboot your phone and all should work, no data should have been lost. (No guarantees)

Please, feel free to copy and paste this where you think applicable, it might answer a few questions and save you some time in answering the same questions over and over again :).
