[Samsung Mesmerize] elijahblake:
After bdemartino wrote his AWESOME thread for the Mesmerize it seemed only fitting that the Showcase get their very own... And since his Thread was Flawless, with his permission I'm mostly copy/pasting word for word.

THIS GUIDE IS SPECIFICALLY FOR THE SHOWCASE

If you're Looking For FROYO Skip down to the bottom of this post to the Section Labled FROYO!!!!!

Keep in mind there are many variations to each step, this is what worked for me the easiest.

And last but not least. There is always the disclaimer that attempting any of this can and will make your phone dysfunctional and or possibly bricked beyond repair (but most likely just dysfunctional which is a pain in the arse to deal with) if you do not follow steps completely (and of a trustworthy source such as xda - ehm and in the appropriate forum ).

So make sure you're in a comfortable environment (not a good idea to be trying to accomplish this while slamming beers at the bar), take your time, read each step that these people have taken the time to carefully write up (then follow it), and you'll be just fine. Be patient as things don't always move fast and you never want to freak out as you may screw things up bad, when it's actually just taking longer than you would expect. Always give it at least 5 minutes before you determine it's looping or crashing or whatevering, there is alot going on behind the scenes, trust me!

Steps to Customize Your Stock Showcase (For Eclair 2.1)

1) Root your phone

. - Basically all this means is gaining the ability to give programs/apps and yourself SuperUser access (equivalent of being admin in windows) and also the ability to flash roms via recovery, detailed below.

The easiest way to root is through the z4root.apk. (an application that will run right on your phone)

Download Here

After download, put z4root.apk on your SD card root directory

Then make sure in Settings->Applications that the "Unknown sources" box is checked.

If you don't have a file manager, download a free one from the market, using the file manager navigate to the z4root.apk and select to install it.

Note: If you need help at this step, no offense I would suggest getting someone with more experience to help you continue on. I'm serious here

Reboot your phone

After it boots, open the z4root app and press root. At this point it is going to hang, give it 2 minutes and pull the battery. Count to 10, put it back in and turn it on. - This is normal

After your phone boots open z4root again and click root, this time it will run no problems and phone will reboot.

NOTE

**IF YOU HAVE PROBLEMS WITH z4root: "give Super One Click a try. It's a package you have to download to your computer, but you get to see more of what's actually going on so you know where it's at in the process. I have only used up to version 1.5.5, and I know that version is very capable for the Showcase on 2.1. It is located here."-This Information provided by phidelt82**

Once you are rooted (you will see the superuser icon in your apps, it will show apps you've given that permission to... eventually) you will need to make sure you have a file manager that can request root permissions (read/write) before you will be able to complete the next step. Search the market for "root file manager" and pick one to download and install.

I use Root Explorer

It's a few bucks, but there's hardly a day that goes by when I don't use it.. (Well worth the money)

Also at this step I would download and install RomManager and TerminalEmulator as you will need these later.

2) Install RomManager and the ClockworkMod Recovery

. These will basically just give you the ability to boot into recovery where you can more easily flash kernel's/rom's and anything else you wish to push to your phone. (Recovery is basically a bios like interface - but it's different than the stock version)

I was able to install the Clockwork Mod Recovery very easily just by simply using the root file manager app I had downloaded, along with following with the instructions.

(In your file manager, MAKE SURE YOU ARE Read/Write not Read/Only, for RootExplorer there is a toggle at the top, other ones you may have to enable this through settings, others may just be R/W by default, you will just have to determine this or google the app)

Download the two Files you need from the bottom of this post

Place both files on your SD card root if you were using a computer to download them or you could always download them through your phone's browser

Using the root file explorer app, move the Redbend_ua file from the SD card to /system/xbin/

Long press on the Redbend_ua file and click permissions, there should be one check missing, check that so that all are marked. Save and exit.

Now open TerminalEmulator

NOTE:

The spaces below are actual spaces and in bml8 there is a lowercase "L" not a "1" there is also a space after cd, after redbend_ua, after restore, and after recovery.bin

TYPE THIS ALL EXACTLY AS SHOWN BETWEEN THE QUOTES

at the command line ($) type "su" (then hit enter)

Type "cd /system/xbin" (then hit enter, which changes directory)

Type "redbend_ua restore /sdcard/zImage /dev/block/bml8" (then hit enter, It will now scroll a bunch of text and reboot.)

After phone boots, open RomManager

Click on Flash ClockworkMod Recovery

Select the Samsung Fascinate your phone will still be the Showcase. This is just what works with our model.

At this point you're all stock and ready for new kernel/rom. (but now you are able to do so very easily)

Accessing Recovery!!!!!

NOTE: There are a few ways of getting into recovery mode. The easiest is to download QuickBoot.

Once installed you can install the widget to any homescreen or just use the app from the app drawer. Once you open the app, click Recovery and it automatically reboots the Phone into Recovery..

You may have to click the install update.zip (while you're on the stock kernel after Voodoo you won't have to anymore)

The other method, which you will need incase you EVER Bootloop! Is the 3 finger method (Hold down the volume up and down keys and the power button all at the same time when you're turning your phone on) Once you see the Samsung splash screen you can remove your finger from the power button, but keep holding down both volume keys!!!

Incase of Bootloop, remove the battery and do this while Rebooting...

AGAIN WHILE YOU STILL HAVE A STOCK KERNEL, YOU WILL PROBABLY HAVE TO *apply sdcard:update.zip* after you enter the FIRST RECOVERY...

The next Screen will be Clock Work Mod, this is where you will want to do your First Nandroid Backup!!!!

3) KERNEL: Install Voodoo lagfix kernel and new 5.0 sound

Now onto Installing a Voodoo Kernel

If you want speed and good battery life (and high standard marks) +unlocking the headphone amp and eq controls (it makes even the samsung headset sound killer) go here and follow those steps for using your now functional recovery mode to flash the new Voodoo 5.0 kernel.

Now you can install Voodoo Control and get new life out of those earbuds!!!

Note:

Just an FYI, after installing custom kernel's you will always have an issue on start up of seeing a flashing black box in the middle of the samsung logo. This can be corrected by installing a custom boot screen (only requires root access) and you can find out how here.

4) Custom ROM : Download and install the ROM of your choice.

Right now we really only have 1 that I recommend..

It's Phidelt82's PicknPack Rom

This is a deodexed Rom which allows you to use MODS and themes. This ROM is 100% Stable, I've been running it for a WHILE with ZERO issues...

MODS/Themes/Customization

NoClock in the Status Bar

Midnight Theme

HoneyComb Digital Clock

Shutdown Animations or Images

Bootanimations with new Boot Sounds

Of course there is WAY more than these listed, but this should fill up your afternoon playing around with your new and IMPROVED Showcase!!!

FROYO FOR THE SHOWCASE = YUMMY!!!!

Yes, for those of you that didn't already know, thanks to Phidelt82 we now have Froyo!!!! I've been running it for about a week and it's Delicious!!!

I'm not going to Write as much as I did for the 2.1 b/c the directions are in the threads already.. Just follow the Directions, if you have any problems after that read through the threads and see if anyone's already figured them out...

And this will work with a Factory Showcase!!!!!

First of all you need to go to:

[Froyo-Odin] Showcase EB11 - Cellular South Update (be sure to Thank Phidelt82)

After this you will have 2.2, now you can use:

SuperOneClick to root your new Froyo Showcase (if you want)!!!

And if you plan on doing Mods/Themes/etc.. You should go ahead and Flash the EB11 Showcase Pick-n-Pack, again be sure to thank Phidelt82 for this!!!

If you flash the PicknPack Rom made by Phidelt82, then there's no need to root... It comes PREROOTED.. You only need to ROOT if you're staying on the Stock 2.2!!!

If you're flashing the picknpack do a Nandroid backup after you're done.... If you're going to stay on the Factory 2.2, do you a Nandroid backup after that...

Thanks to lmartin92, JT1134, Phidelt82, we now have a voodoo kernel with lagfix for 2.2 which can be found HERE...

If you're new to using voodoo lagfix kerenls.. Remember to always disable lagfix before doing Nandroid Backups/Restores/Flashing mods/Themes for YOUR SAFETY

I'm working on a few themes... sbrissen has already Made us the NoClock and NoAmPm mod (you have to be on the picknpack for these)

For a list of the Mods/Themes/Roms for the showcase look HERE
