    Default Should I go to ext4? Looking for advice...

    Hey everyone.... Just came over from an evo about a month ago... The evo forums are very active and helpful so I thought I'd pose some questions...

    I have a lot of experience flashing evo roms...

    What I'm wondering is if it's worth it to go to ext4????

    And if I go to ext4 what's a good rom to start with?????

    Thanks in advance!!!!!

    P.s. I forgot to say that I'm already rooted and on ec05...

    Welcome to the EPIC 4G.

    Next, yes you will need to go EXT4 conversion to run most of the EC05 based ROMs. As far as a good ROM basically they all run very well and come down to personal preference.

    Note: While your currently rooted running CWM 2.5.1.0 (RFS filesystem) you do have the option of trying out the leaked version of Gingerbread. There is a link available to it here in this section.

    When you feel you have cwm 2.x down pat, I say move on to ext4(cwm3.x) you need to learn the pit falls of ext4 no journaling. Poor power management and improper shutdowns can and will lead to corrupt data. Making a backup in cwm3 and then restoring it after flashing a new rom will turn journaling on and give you a little more wiggle room from the dreaded data corruption of improper shut downs.

    Just remember this is an android phone, but not everything is the same as the evo.....research=good assumptions=bad.....enjoy!!

    The first thing I do on any new rom is enable journaling. Some people don't like losing the small amount of doped that journaling causes. Some people worry that their nand memory will die too soon from the extra writes. I have tep On my phones so I don't worry about that.

    I have had good luck with syndicate bonsai urbanfury and simply aosp. All on ext4. Before I learned to enable journalling though I would get random force closes here and there from corrupt data. Its not really a big deal most of the time you fix by just clearing data on the offending app. Now it never happens. Always keep a known good clockwork backup just to be safe though.

    Wow fellas it looks like I'm a little more of a noob than I thought.... There's a lot of terms being thrown out here that I didnt see in evo-land....

    I have no problem with the conversion process but it sounds like you guys are saying it's not very stable... I can really take a chance on having my battery life be worse...


    Any advise???? Thanks for the info you've given already....

    EXT4 is your only options really if you choose to run custom ROMs. There are a few that support RFS (stock filesystem for Epic 4g) but the goods is running EXT4. EXT4 itself is stable and the ROMs are too, the part that some people have troubles with is the journaling and no journaling on ROMs. It has to do with the amount of times data is written to your device while running.

    An easy way to think of it is, running an EXT4 ROM with no journaling is like going fishing without a net. It can be done, its less tackle to carry and more efficient but eventually you will loose that big fish your trying to land. In phone terms your device will suffer a lockup or unforeseen problem and cause you to pull the battery to recover which at that point most of the time ends up with data corruptio.. Then the next time you boot up your met with FC's that sometimes can be overcome but some can't and you end up having to wipe and reflash the ROM worst case.

    Now, journaling enabled is like a safety net allowing more data writes to your disk resulting in less chance of data corruption in the event of a crash or lockup. Performance they say is a tad slower but I have never really noticed a difference between the two.


    What causes lockups normally is from a kernel not agreeing with what your asking it to do or even that it just doesn't gel well with your device as not all devices are created and act equal. Kernels is a trial and error sometimes to find the one that works good with your ROM choice and device.

    Hopefully what I have said helps clear things up. Bottom line you want to run custom you need to go EXT4 and then choose if you want to run journaling enabled or not. Otherwise life is the same as your EVO days, backups and restores and flashing themes, etc and having fun.

    Anything else just ask.

    Do you see a lot of speed difference with ext4 compared to Rfs????

    What about the difference in battery life...

    I'm fairly happy with stock (minus bloat) except I really wish the UI would respond faster.... Especially when opening and closing the keyboard....

    Yes you will see a difference with EXT4 over RFS setup. Its a lot snappier and you can tell its performing much better. Battery life is going to be better because the custom ROMs all have custom kernels with undervolts which enhances battery life and speed/performance if wanted.

    If you want to stay stock and just root to get rid of your bloat thats fine, but your not going to have much more that you can do with stock RFS rooted when compared to custom ROMs. I'm not trying to sell it to you, just pointing out the pros and cons.

    We have many options available for you to get rooted on EXT4 and running custom ROMs so sit back and think things over and let us know we'll get you pointed in the right direction if you choose to go EXT4.

    Thanks Paul, I did not know why I have problems with gmail. Now I understand issue. I am running SRF 1.1.0 and Baked Shack 2.3. I do not care if I have to flash the Rom every now and then as long as I have my good battery life and good speed I can live with that.
