When Google released Android 4.2.1 I was pumped, and not just because it has a Siri-like voice search feature. But, like many other smartphone owners who purchased a Samsung Epic Touch, I knew an official update through Samsung would never come. That’s why this guide will show you how to get Android 4.2.1. working on the Epic Touch 4G (SPH-D710) via a community-driven Cyanogenmod (CM) 10.1 rom.
This rom is a ported version of CM 10.1 from an XDA user named dastin1015. After testing it out for a couple days, I have to say that this rom rocks. Myself and others XDA users are in agreement that it offers even better stability than the official CM 10 beta 2 rom (which is still on Android 4.1), and it has better performance as well. Needless to say, it completely blows away the bloated and glitchy stock ROMS released by Samsung. It’s the best ROM I’ve seen so far for the Epic Touch, and so if you have one of these phones I’d consider it a necessity. Ready to get started?
Download list – You’ll need all of these
- Direct-boot CWM5
- Odin v1.85
- Samsung Drivers
- The most recent build of CM 10.1 (save to your phone SD card) [picture]
- Google Apps for JB 4.2.1 (save to your phone SD card)
Note: If you are already running CM10 Beta/Alpha (4.1.x) you should be able to directly flash to 4.2 and shouldn’t need to use Odin or the Direct-boot. If the direct boot CWM is not working you may need to flash the EL29 stock rom before continuing.
Warning: Rooting / Flashing roms / etc can void your warranty. However, you can always just flash back to stock before sending it in for repair, and as long you don’t tell Samsung you flashed it you usually can retain your warranty. Also, if your phone breaks I am not responsible. This guide has worked for me and has been tested on two Epic Touch 4Gs.
First off, we need to transfer the latest build of CM 10.1 and the Google Apps zip files to the phone. Depending on what ROM you are running, this is usually just as simple as enabling USB transfer via your notification drawer after plugging in your phone to your computer. Alternatively, you can just download the two links above using your phone’s browser so that it saves directly to your mobile device.
The full filenames for these two files that need to be on your phone are:
Note that WILD-FOR-THE-NIHT will likely include a a more recent trailing number as it is updated frequently.
Once you have the two files on your phone, the Epic Touch needs to be rebooted into Download mode. To do this you need to first turn the phone off. Next, while the phone is off simultaneously press and hold the Volume Down and Power buttons. The phone should boot up to a Warning screen. Here press Volume Up to continue, and then you’ll be on the Downloading screen (also known as Odin Mode).
Now make sure your phone is connected to your comptuer, and then load up the Odin3 v.185.exe file that was in the Odin zip. You can also move the E4GT-EL29-directbootCWM-v3.tar.md5 to the Odin folder if you like, but it isn’t needed.
In Odin itself don’t touch anything except for the PDA button. Click the PDA button and then browse to the E4GT-EL29-directbootCWM-v3.tar.md5 file and click Start. This should take about 20 seconds, and when your done the phone should reboot into ClockworkMod Recovery.
The first thing we need to do in ClockworkMod is wipe data. Perform the following using the first menu and the “advanced” menu. To navigate you’ll have to use the Volume Up/Down buttons and the Power button to select (some versions of CWM use the Home button).
- Wipe data/factory reset
- Wipe cache partition
- Advanced > Wipe Dalvik Cache
Once you have everything wipe select to “Install zip form sdcard.”
Now what you choose on the next menu will depend on whether you saved your files on your internal SD or external SD. Choose the one where your CM 10.1 and gappsjb… files are.
Now just flash/open the two zips in the following order:
This should take about 2 minutes to finish. Once you are done, use the back button to go to the menu and select “reboot system now.”
Once you’re phone reboots it should be running Android 4.2.1 via Cyanogen Mod 10.1. Have fun and enjoy the increased battery life, stability, performance, and features.
