    I want to flash Azrael 4.0 to my evo. I want to make sure that I understand all steps before flashing.

    I already have rooted my evo, did nand backup , installed titanium backup and backed up my apps , what's next?

    - Reboot into recovery , wipe data , cache, Dalvik, SD EXT. DO It twice
    - install the ROM from SD card , let it install and boot
    - how do I restore my apps? Is titanium going to be there when I install the ROM?

    Do I need with Radios? Anything else ?

    1) Go to menu->settings->about phone->Software information. What do you see for your current radio and PRI versions? If they don't match the latest from here:

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

    Then you must flash the new radios. See the Rooting for Dummies guide - section 6 under after rooting for instructions on how to flash the combo update.

    2) If you do need to flash the radios, combine it with flashing the new ROM (Azrael in your case). If not, then just skip the radio part. You've already made the appropriate backups, so to flash the ROM, just reboot into recovery, and wipe data, cache, and dalvik. Do you have an ext partition on your card? If you do, wipe it. If not, there's nothing to wipe. Some people say to wipe 2 or 3 times. You can if you like.

    3) You've got that step right. Just flash the ROM.

    4) Once you boot up, it depends entirely on whether or not the dev included titanium backup. I haven't checked for Azrael, but if it's not there, go download it from the market. Once that is done, you can start restoring. I highly recommend that you restore only the apps you know you need, and restore app data only when necessary. To avoid any conflicts, you should also change your settings manually rather than restore them with titanium backup. Yes, it takes longer, but you'll save yourself from potential headaches.

    Another option to make sure that you have titanium installed is to create a flashable zip from within titanium. It isn't as hard as you think, Titanium does most of the work for you. If you want to sign the zip (makes it easier to flash), download Zip Signer (by Ken Ellinwood) from the market.

    In Titanium, Menu > More > create Update.zip. Select the options you want and hit create. Then you just flash it after you flash the rom, using the same process.

    Looks like everything is up to date

    What kind of settings are you talking about?

    How do I install a theme? same as flashing the ROM?

    I just mean all your system settings. Titanium backup gives you the option to backup apps (plus app data) and system settings. System settings would be things you change in menu->settings, for example. It's better if you change all that manually after you flash a ROM.

    Flashing a theme is about the same. The only difference is that you don't need to wipe data. Still wipe cache and dalvik, though. Also, make sure the theme you are flashing is compatible with your ROM. Most Sense ROMs are compatible with most Sense themes, but make sure first. Some themes might include mods that aren't supported by you current ROM and vice versa.

    EDIT: I edited the above where I said to wipe cache and data when flashing a theme. I meant to type wipe cache and dalvik. Thanks to JB in AZ for pointing that out.

    No worries, just happened to catch it. :) Reading, reading, reading....That is the key to understanding!

    Must mean it's working...I am getting more used to the procedures on the EVO...They are similar, yet just a little different from the procedures on the Hero, that I am more familiar with.

    But I will still look to you, akazabam, for guidence. :cool: So again, thanks for everything you do here!

    Ok, flashed the ROM and Theme, everything seems to be working fine, but my contacts that are linked to facebook, their images are not showing, any ideas?

    Haha, well thanks for keeping me in check :p. Sounds like you're picking up everything very quickly :).

    You flashed Azrael, right? I assume you logged in to facebook via Facebook for HTC Sense? Go to menu->settings->accounts & sync. Then select Faceboot for HTC Sense. Do you have the option for "sync contacts" checked? If not, select it. After you've checked it if you needed to, select the option to sync now. See if that fixes it.

    Have you tried just rebooting the phone? Sometimes that helps when nothing else does.

    Lol, No problem :). Don't worry, the easiest thing isn't always the most obvious.

    ^ it also takes a good bit of time depending on the number of contacts. It has to download all of those pictures :)

    So true, and as a side note, may explain why many people's first reaction to a new ROM is that is seems "sluggish". We may want to think about explainng this more in the stickies and guides. :)
     
  16. akazabam

    akazabam Android Expert

    Yes, that's true. Typically, if it shows that it's syncing, that'll definitely be an issue. It shouldn't take *that* long though (unless you have hundreds of contacts).

    I would say that typically after a fresh start it takes about 30-45 minutes for everything to settle down. Calendar Facebook Contacts etc. This is all going to be dependent on connection of course. Doing it while a wifi connection is available is really going to make things faster.

    I want to clean some space on my SD card. I came across 3 backups.2 are from clockworkmod and 1 ra , can I delete the 2 from clockworkmod recoveries ?

    When buying a new SD card , could I just copy everything from old to new ?
     
  19. akazabam

    akazabam Android Expert

    If you never intend on flashing clockwork back and restoring those nandroid backups, then feel free to delete them. It won't harm anything; you just will never be able to restore them again (obviously).

    Yes, when you buy a new card, just copy everything from the old card to the new one. It's up to you how you want to do that, but the easiest thing to do is to put the new card in the phone, put the old card in a card reader, connect the phone to the computer via usb, then copy from the old card to the new one.

    Just got my new SD card, Do i need to do anything to it like formatting or anything? before I copy the old to new
     
  21. akazabam

    akazabam Android Expert

    Well, it *should* already be formatted. If you're going to use a2sd, then you'd want to put an ext partition on it, first, in recovery. If you're not going to do that, just put the card in, boot up, and verify you can access the card, and read/write data to it. Then just copy your stuff over. Like I said, though, you're going to use a2sd, partition it in recovery, first, as that will wipe the card.

    Ok, It's time to unroot. I need my speaker replaced and power button checked out .

    I backed up all my apps and data. I still have the stock ROM backup on SD card. Do I just flash the stock , how do I remove the root so the Sprint rep can't see that my EVO was rooted.

    Never mind, found the process for unrooting. Will I be able to restore my backed up apps when I unroot?
     
  24. ocnbrze

    ocnbrze DON'T PANIC!!!!!!!!!

    titanium will work only on rooted phones. app list backup is probably a better option if you are going to keep it unrooted. if you re-root you can use titanium to restore.

    I will go back to root after finished with Sprint.

    Can I flash my stock backed up ROM , then only unroot ?

    Is there going to be any evidence on SD card of being rooted ?
