A more specific FAQ section for the One (For general FAQ scroll down a bit)

1. When I try to enter recovery it just blinks for a second and the phone reboots. How do I get into recovery?

Use Vol-Down + Power to enter fastboot mode. Now connect the phone to the PC and use 'fastboot erase cache'. After that it should be able to boot recovery correctly.​

2. The phone rebooted itself while installing the ROM, now it just bootloops. How should I recover my phone?

Reboot into recovery and flash again. If recovery won't load, check FAQ 1.​

3. Do I need to wipe my data everytime I flash a new version?

No, a data wipe is only needed when you come from stock or another custom ROM. It is also recommended but not manadtory to wipe when there is a base update. A wipe is needed if you want to go to GE ROM​

4. Do I need to flash boot.img seperately?

No, the installer will flash it for you.​

5. Can I flash this ROM on my T-Mobile / AT&T / Rogers... variant?

Yes, you can. The ROM will work on all the variants except Sprint, as it has some significant differences. Sprint is supported only with version 31.6 as of now. WiFi calling is available in version 31.6.​

6. And where do I get the old versions?

7. I am on AT&T and my signal is much lower than on stock ROM. How do I fix this?

In fact your signal is not lower. The lower singnal bar display is a cosmetic issue. To check your actual signal strength go to Settings->Info->Network and look for the dbm value. When you compare this you will notice your signal strengh is okay.​

8. I forgot to select an option in AROMA / I don't want a mod anymore. How can I add/remove it afterwards?

Reflash the ROM with the desired options. No wipe required.​

9. How do I get rid of the 3-dot-menu?

As of the 4.2.2 update HTC introduced the Long-press-home-as-menu functionality, which also removes the black menu bar. Activate it under Settings -> Display -> Home Button.​

10. Volume-wakeup mod doesn't work sometimes, is there a fix?

Some variations of the VolWake mod won't work in deep sleep mode. You need to use another variant, like inside a custom kernel.​

11. Speaking of kernels, which one do you recommend?

This is mainly a matter of personal taste. I use the stock kernel included in AR HD. It is stable and works nicely. You are free to try other kernels, but make sure you report kernel issues on the kernel's thread.​

12. When will you upload version x.y?

Please, don't ask for ETAs. It will be uploaded, when it's done ;) Sometimes, Mike likes to take a nap!​

13. Can you include the super awesome mod xyz?

This ROM is meant to be an optimized stock ROM with some important mods in AROMA (APM, %battery etc). Please note that adding more mods also adds possibility for bugs, and increases the size of the ROM.zip​

14. Do I need to update my radio/firmware to flash the ROM?

It is not needed. You can do it if you want to. Newer radios/firmwares can improve signal, bluetooth, WiFi... refer to the following thread for more information: http://xdaforums.com/showthread.php?t=2182823​

15. Does the ROM include radio/firmware/hboot...?

Nope.​

16. But I really, really want to install firmware! How to do it?

Check the awesome work by vomer and makbil here: http://xdaforums.com/showpost.php?p=42556698&postcount=24958 and here: http://xdaforums.com/showpost.php?p=42586614&postcount=25330 . Please remember, that this is NOT the firmware thread. You better ask questions related to it in the corresponding thread.​

17. My Facebook app lags. How to make it smooth again?

Enable Force GPU rendering in Settings -> Devoloper Options -> Advanced​

18. Before I flashed the ROM my phone's speakers were louder. How can I fix it?

This change was made by HTC. It has nothing to do with AR HD. It may change in the future again.​

19. How can I remove Kids menu?

Install either APM mod or use the xposed framework and MoDaCo Toolkit. It has a mod in it for removing the Kids menu from APM. Xposed is available in AROMA, MoDaCo Toolkit is a seperate download. For removing the actual app, you can use TitaniumBackup and use it's function to remove system apps.​

20. My WiFi passwords aren't stored anymore. How can I fix this?

You have probably selected the AT&T option in AROMA. For a quick fix reflash the ROM, select international version (no wipe needed, please see FAQ 7 for a note about signal bars when using the international version on AT&T)​

21. How do I remove the power saver notification?

You can use xposed+MoDaCo toolkit or the following App for that: https://play.google.com/store/apps/details?id=com.jmzsoft.powersaverdisable​

22. How can I get larger MMS sizes without doing a full wipe?

Please check the guide here: http://xdaforums.com/showpost.php?p=42471350&postcount=24137​

23. How can I change the order of EQS?

Please check the guide here: http://xdaforums.com/showpost.php?p=42609830&postcount=25496​

24. I have an error about UID. How can I fix it??

Please look in the folder /data/data/. If you have something from Quadrant there delete it. If that didn't help checl /data/system/uiderrors.txt. You may need to delete the quadrant folder from recovery.​

25. My issue is not mentioned here and/or my phone is still not working after trying to recover. What should I do?

You are always free to post in this thread or join IRC. You will find helpful members who will support you in solving your problem.​

General FAQ

Q 2: My Premium Navigation doesn't work correctly. What should I do?

A: Your Premium Navigation may not work correctly for many reasons. Most of them are not ROM related. You can try the following things:

- reinstall your Locations under "Settings" ---> "Locations"

- remove /sdcard/.data/navigator/Data/Temporary from your SD card

- re-download Google Maps from the Android Market

- clear data from Google Maps in system software management

Q 4: After I reboot my device, mp3 ring-tone is back to default. What should I do?

A: Go to Ringtones > Menu > More Ringtones > Create new ringtone > Select the one you want (Thanks to kill4l)

Q 6: After flashing Android Revolution HD my SD card is being mounted as ready only. What should I do?

A: Connect your SD card to your PC and do defragmentation process. If you still have some problems with SD card, please read this.

Mac users can use the repair function of the MacOS disk utility to solve the read only problem (Thanks to Calimero1205).

Q 8: Do I need to wipe data partition when upgrading from old version of Android Revolution HD?

A: I always recommend wiping data partition but it's absolutely necessary only if I mention that in the changelog. But normally you can live without it.

Wipe data partition if you experience any issues.

Q 10: I had SetCPU installed on Android Revolution HD, then I flashed new version of AR HD and SetCPU doesn't work any more. How to fix it?

A: Please reinstall SetCPU.

Q 12: My phone got random freezes or reboots. How can I fix it?

A: Every CPU is different. It seems that your CPU doesn't like OC or UV (undervolt). Set your CPU to default 1GHz.

If it doesn't help, then you need to flash default kernel from the second post.

Q 14: My GPS signal is very weak or GPS is not working at all. How can I fix it?

A: There are some solutions:

1. You can download and install FasterFix to improve your signal strength.

2. You can download and install GPS Status & Toolbox to manage your GPS settings.

3. Turn off "Fast boot" under "Settings" ---> "Power" and reboot your phone.

4. Read this, this, this & this

Q 16: My Quadrant score is not as high as on different ROM. What does it mean?

A: It means absolutely nothing. Benchmarks on Android System are more or less lottery and they are not showing the real system performance.

There are many settings that can force Quadrant to show more then 3000 points but it's faked performance, that actually can slow down your phone in some circumstances.

What I always emphasize is a real performance, the one you can feel under your fingers. Remember that I/O has some limit and surpassing it shows just a numbers without true ratio.

Also keep in mind that Quadrant has support for Android Gingerbread only in version 1.1.7 and higher.

Q 18: My screen-lock sound and keypad sound while dialing numbers is very low. How can I fix it?

A: Download "Quick Settings" application from Android Market and check system volume slider.

Q 20: My Wi-Fi doesn't reconnect automatically after boot. How to fix it?

A: Disable fastboot in settings or check this solution.
