    I have an EVO 4G, while running 2.1 I rooted the phone so i can thether. all works fine. My question is do I need to reflash to an original 2.1 rom in order to upgrade to 2.2 or higher. The reason I ask is when I try to upgrade the software through Sprint to 2.2 it crashes. So Im thinking it senses the phone has been rooted. If the answer is yes. I have 2 more questions. 1. Will the flash reset my entire phone reseting everything Ie contacts and such or will it just reset the android. And the other is where can you get an original virgin 2.1 or pos a 2.2 rom thats has not been messed with and is safe safe.

    If you want the Sprint updates on your phone, do not try the OTA upgrade. Instead, just flash this ROM:

    [ROM]RUU_SuperSonic_S_Sprint_WWE_3.30.651.2_Radio_2.15. 00.09.01_NV_1.77_003_release - xda-developers

    This is the latest stock Evo ROM that INCLUDES the Sprint updates.

    Before flashing any ROM, however, you should follow the guide found here:

    Particularly sections 3, 5 and 8. I don't ever use ROM Manager as this thread suggests, but most people seem to like it. These steps will basically guide you through making a nandroid backup (in case something goes wrong which is highly unlikely), how to backup your apps/data using Titanium Backup, and then how to flash a ROM.

    To answer your question 1, when you flash a new ROM it will completely reset your phone. This is why, however, I directed you to how to back up your phone using Titanium Backup. Also, your contacts should all be saved on your google account so those will load back on your phone once you sync google again.

    I hope this makes sense. Just let us know if you have questions.

    If the OP is going to unroot his phone, he needs to use:
    *OFFICIAL* RUU_SuperSonic_S_Sprint_WWE_3.29.651.5_Radio_2.15. 00.09.01_NV_1.77_CNV_re - xda-developers

    The software version 3.30.651.2 is only released to certain new EVO's that include different hardware. And 3.30 is not root able at this time so if the OP changes his mind.

    Now if I were you I would stay rooted. Simply just flash any ROM thats based off of the current Sprint OTA's. Then once you find a ROM, update your radio here:
    [Update] Radio and PRI Version 1.77 - OTA 3.29.651.5 - Sept 23rd 2010 - xda-developers
    (current radio

    And update your PRI here:
    xda-developers - View Single Post - [Update] Radio and PRI Version 1.77 - OTA 3.29.651.5 - Sept 23rd 2010
    (current PRI 1.77)

    Good luck!

    Ok so stay rooted and flash 3.29 not 3.30. But why do I flash the Radio and the PRI as well arent they in the 3.29 rom.

    First, yes...much easier than unrooting, accepting the update and then rerooting

    radios etc:
    usually they are some users prefer the old radios over the new ones....all area specific and user preference.

    some radios work well in areas that the new ones do not and vice versa

    Pretty much what everyone else in this thread has said is true. You just need to flash a ROM based of the latest OTA and also flash the latest radios, etc. I can certainly give you some updated links.

    First off, if you've never flashed anything, follow the instructions here:

    It's very important that you backup first.

    You can flash any ROM you like that is based on latest OTA (3.70 now). Find the list here:

    HTC Supersonic/ROMs - XDA-Developers

    You will also need to flash your radios, etc. separately. You can find a constantly updated list here:

    [ Radios ][ 12-17 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions - xda-developers
