AT&T unlocked but no wipe davlik

---

Hi guys,

I have a Bravo AT&T unlocked (Android 2.1 v1) and there are a lot of apps that simply don´t work (radio, market, etc).
I decided to install a custom ROM (Kobe 2.2.10) and following the instructions I have to wipe dalvik cache. I cannot find that option when I boot, there are only wipe data and wipe cache partition.
AS you may see, I´m new to Android environment so your suggestions would be much appreciated.

Another question: do I need to upgrade to gingerbread or this is made by simply installing the ROM?

The wipe data/cache will work -- dalvik cache is stored on the /data partition; but you'll lose all installed apps as well. If you're rooted, use Titanium Backup or similar to back up any apps as needed. I posted my app backup method at the bottom, but its a bit complicated and requires using adb and modifying the updater-script of what ever rom you're going to flash -- well, noob complicated anyways.

You need to flash the 2.2 sbf first since ALL our roms are based on it and the Froyo kernel. 2.1 is Eclair and afaik, no roms are made for it.

Then I'd skip that 2.2.10 rom since it's out dated. For stability, the roms go as follows -- CM7 -> Pikachu MIUI\2.4.20 MIUI -> MS2 Ginger (no camera\tethering) -> CM9 -> BravoX -> Stock. That said, CM9 will soon be at the top of the pack in the next month or two... I'd start off with CM7 if I were you, just to get the hang of how everything works and then go from there. MS2 also has very good battery, but no camera or tethering -- which doesn't matter if you use US ATT since it does an entitlement check to see if you pay for tethering. (Pisses me off since I only tether my home WI-FI, never 3g. Why should that cost me $20 a month???)

From the what you typed, it sounds like you're trying to flash a rom from the stock bootmenu which will not work. You first have to install Defy 2nd-Init, then install the rom from that bootmenu.

There is no "real" gingerbread for the Bravo, only GB roms built for the Froyo kernel. While the Bravo is fully capable of running GB, ICS, and probably Jellybean as well (Android 4.1.0, not released yet), Motorola would rather us buy new phones then update our software -- the crux of all but maybe 3 or 4 Motorola phones due to us having locked bootloaders.

Here's my app backup method

adb pull /data/app ~/Documents/data/app

Open updater-script of rom you're going to flash (/META-INF/com/android/google/updater-script)

add the following 3 lines right before the final line

package_extract_dir("data/app", "/data/app");
set_perm(1000, 1000, 0771, "/data");
set_perm_recursive(1000, 1000, 0771, 0644, "/data/app");

add the pulled /data/app/ to the root directory of the zip so it looks like

data
META-INF
system

and flash the zip with all you're apps preinstalled and working -- you lose app data this way (settins, passwords, etc), but latent app data from one rom to the next can be bad news.

A trick is to do the above with a TB backup, then use TB to restore the app data for select apps that have a ton of settings to configure, but that can be dangerous if you go from say romA 1.0 to romB 1.0. RomA 1.0 to romA 1.1 is safer for restoring app data.

Not dangerous as in brick, more like the app will just FC on opening up. Its best to just ignore app data and just reconfigure everything.


I should add, if you don't require tethering or camera, then MS2 could be at the top of the list. Its an awesome rom with great battery life and stability.

thanks for the tips, I´ll try to implement them this weekend.

Since the phone is new and I don´t have any personal apps that I particularly use, do I need to make any backups? Do they come with CM7?

No, CM7 pretty much has it covered, unless you use the ATT or Blur Apps. You may need to find a market replacement for those.

If you do use the ATT\Blur Apps, then you could install MS2Ginger, but the camera and data tethering doesn't work with it -- its still one of the most stable\battery efficient roms out there. If it wasn't for the fact that I tether my wifi daily (I am right now) and sometimes the Bossman needs pictures from the job, I'd probably run MS2 as my primary stable; but CM9 works well enough now -- except yesterday when my baseband quit working out of nowhere, all I did was install a theme and reboot....Ended up restoring my Pikachu Backup since I on the way to work and needed stable.

Why wait till the weekend -- its a 15 minute process, and I'm including flashing the sbf and rooting the device.

As far as mods and all that goes, I'd stay away from the Touch Recovery. Reasons -- it doesn't like big Aroma Installer roms (wouldn't even start my 450mb Wiui I was working on), sometimes it just doesn't work, and data wipe also wipes sd-ext (where I store data I don't want being fragmented by vfat). It'll be awesome once its a bit more stable; just not noob friendly yet.

I suspect the Aroma not working with Touch is because /tmp is mounted to ram, and it just can't extract a 450mb rom in to ram and have the system fully working as well.

What sucks, is with little modification, the system will run the sdcard as ext3; except that mediaserver actually checks to see if the card is vfat and will fc when it isn't. And you cant make a 10mb vfat partition and symlink it to sd-ext either since vfat doesn't support symlinking. None of that really matters to you, but the Touch part reminded me of my most hated Android requirement -- vfat as the only filesystem of sdcard primary partition.

HELP

Installing SBF I`m stuck at step 10: the red M logo appears but the phone doesn`t respond to anything. Trying to wipe data in stock recovery but no buttons /button combination seem to work.

Whit the phone off press volume down button and power button, when you are in recovery mode where you see the android logo with exclamation, press both volume buttons at the same time.

thanx, I`ve just done that in a desperate move and it worked!
