Getting started

There is a lot to know about the Epic 4G touch. This wiki covers almost everything you might want to know and more. If you are new to the phone, rooting, installing ROMs and kernels, etc. then the following resource is a great place to start.

Safely Flashing Ice Cream Sandwich - Q&A

As we progress towards an official release of Ice Cream Sandwich for the Epic 4G Touch there are many things users should know before diving into the current unofficial builds. There is risk using any custom firmware on your device, however, Ice Cream Sandwich has proven to increase that risk if things are not done correctly. xST4T1K put together an excellent thread for the community to ensure you are as safe as possible when upgrading to an Ice Cream Sandwich ROM, whether it be Touchwiz or an AOSP build. It is highly recommended you see the thread below before proceeding to anything ICS.

Questions and Answers

  • Question: Are we able to use a clockworkmod based recovery in Ice Cream Sandwich?
    • Answer: Currently it is not recommended to use a recovery on Ice Cream Sandwich. Wiping anything in an ICS ROM from ICS recovery has consistently resulted in expensive bricks. As for flashing, some have had success flashing zips through ICS recoveries, however, proceed with caution. The safest way to wipe/flash anything in recovery from a ICS ROM is to odin the EL26 CWM repacked kernel, flash what you want, and then flash your ICS kernel in the same recovery. Flashing an ICS kernel while in the EL26 gingerbread-based recovery is a must, ICS will not boot on a GB-based kernel. You will often find that there is an ICS-based kernel in your ROM's installation ZIP.

  • Question: Why don't we have custom recoveries in select ROMs?
    • Answer: See above. This is a precaution to limit the amount of bricks.

eMMC hard-brick bug

This is one of a handful of devices that Samsung has publicly (albeit quietly) admitted that the firmware of the eMMC card in the device is faulty, and could lead to a hard brick under certain circumstances. The brick bug is triggered when executing a block-level formatting in the recently released ICS OTA (and related ICS leaks leading up to it.)

  • More simply, this fatal format process is triggered:
  1. when users do a 'factory reset' in the stock ICS OTA ROM which wipes /data partition. This OTA is being pushed from Sprint to Sprint-consumers' E4GT phones running EL29 stock, from 7/13/2012 - 7/20/2012. A manual update is also available from their website.
    1. Do not factory reset if you're running the FF18 OTA! You have been warned.
  2. when users with rooted ICS-based kernels use recovery to wipe anything (unless using an ICS kernel marked as 'safe'.) 3rd party kernel developers discovered workarounds in June 2012, but, as always with rooted code, some risk still exists. (See Disclaimer)
  3. possible other scenarios where formatting anything on the internal storage chip is involved (such as flashing a ROM from an unsafe ICS kernel recovery, as most rom zip's trigger a format)

This bug does not effect users still on Gingerbread EL29 stock or earlier (and related 3rd party variants.) Samsung is supposedly working on possible fixes, but as of 7/18/12 the status of any publicly available fix is entirely speculative. The FF18 kernel source code released earlier this month in tandem with the OTA release is reported to still contain the triggers for this bug.

If you're not happy with the looks of the software you are running then you might want to checkout the theme database. Make sure the theme you choose is compatible with your software version. If you're not sure, ask your developer.

Kernels are the middle man between your devices software and hardware. Kernels are specific for some builds. If you use an AOSP ROM, you need an AOSP kernel. If you use TouchWiz then you need a TouchWiz kernel. With Samsung phones, the kernel also includes recovery. Not all kernels (or ROMs) have a custom recovery and therefore once they are flashed, you may lose the ability to flash or restore a ROM until a kernel with a custom recovery is flashed via ODIN or Heimdall. You may find a list of kernels for the Epic 4G Touch in this database.

Odin is a software program used to flash your Samsung Epic 4G Touch. Primarily, this is how one achieves root, however it is a great tool to use whether you're just flashing ROMs or restoring back to stock. ODIN is only compatible with a PC running Windows OS.

Using ODIN to flash your Samsung Epic 4G Touch


Heimdall is a cross-platform open-source tool suite used to flash firmware (aka ROMs) onto Samsung Galaxy S devices. It runs on Linux, OS X and Windows (XP, Vista, 7 etc.). It is an alternative to the proprietary closed-source tool ODIN which only runs on Windows OS.
