After flashing the prepare.zip, you should be doing everything in CWM 2.5.1.2. I believe you can get there by going to Advanced->Reboot Recovery while in 2.5.1.0. If not, you may need to Odin back to a fresh rom.

Another thing, according to what I have read, you should flash QR immediately after formatting to ext4, and then flash the most current kernel (unless you add it to the rom), before rebooting.

Anyone having GPS issues? My GPS signal drops in and out several times while navigating. Didn't have that problem with previous rom.
[Epic 4G Android Development] codest3r:
As a matter of fact, yes!

I did a 20 hr trip w/ nav on Q2.1 no problems just before christmas.

After this upgrade to Q2.5 w/ EXT4 Google Nav randomly loses GPS signal. Not for long, usually less than 30 seconds, but on a 4 hr trip it probably happened half a dozen times with clear view of southern sky through windshield.

[Epic 4G Android Development] aggreyj:
Thanks for the advice, I missed the note that said you had to be on 2.5.1.2, I flashed prepare and did that and looks like its working fine now.
[Epic 4G Android Development] thizzmaster:
not bad it all worked out according to the video...

the phone feels a little more responsive and the quadrant score is 1474, which I know doesnt mean much but linpack gave it 13.795 not bad

Anyonr having problems with google nav? Mine is getting stuck at checking navigatiin availabailty.
[Epic 4G Android Development] visions138:
You must reboot in Advanced to get to .2 you can not install any roms if you have EXT4 on .0 .... reboot recovery if its .0 goto advanced the hit reboot recovery it will bring up .2 then wipe x3 for all 3 then flash the rom and next flash the kernel.. your good to go from there
[Epic 4G Android Development] darren.wlsn1:
or just use "quick boot" ap from market, free and it takes you to clockwork for ext4 flashing if ext4 is on ppc.
[Epic 4G Android Development] TheBurgh:
I have the same problem. I had to uninstall the maps update to get the navigation to work.
[Epic 4G Android Development] Dameon87:
Confirmed. Ill look into it, but its probably a problem with maps.
[Epic 4G Android Development] TheBurgh:
Thanks for making ext4 available to the community. GREAT STUFF
[Epic 4G Android Development] spf2722:
I did finally get maps and nav to work, it needed patience.
[Epic 4G Android Development] TheBurgh:
Please share your secret. With 3 kids may patience is werry
[Epic 4G Android Development] lloydcabraham:
I wonder if it's a problem with the rom or the EXT format. Any clues anyone?
[Epic 4G Android Development] mattallica76:
It's not the ext4. It's the GPS fix included in the ROM. If you have working GPS already before you flash it, it seems to cause intermittent GPS issues. I removed it from my phone and my GPS went back to working perfect again. I suppose it might help to leave it if you have a phone that struggles with GPS issues.
[Epic 4G Android Development] Dameon87:
Thanks for the report. I suspected it was that. Ill remove it in the next version prolly tomorrow night.

[Epic 4G Android Development] abmcbride85:
If somebody already commented on this I'm sorry but has anyone else had trouble with installing the AOSP lock screen. I get an error when I try to flash it. Any fix or work around? Thanks
[Epic 4G Android Development] MysteryEmotionz:
Are you flaking the dk28 lock screen from raiderep?. Its nurtured in the dk28 lock screen thread and in the op off my theme. It might be posted in other areas.

Reboot into recovery using quick boot. Make sure your in the recovery that ends in .2. If not use the same method had the 3 finger recovery. boot into recovery goto the advance options. Select reboot recovery. That should port you in the recovery ending with .2. Flash threw there like you would flash normally
[Epic 4G Android Development] mattallica76:
Use a file explorer or adb to navigate to data/gps/. Then delete the file named secgps.conf, then reboot. Android should replace the deleted file with a new one upon reboot.
[Epic 4G Android Development] abmcbride85:
thanks. worked like a charm. i was trying to flash it with the recovery ending in 0 not 2. i feel dumb... haha

Ive been using the 2.5 rom for a few days, Im actually noticing a decrease in performance from the old file system :confused:

games are taking longer to open and theres stutter sometimes navigating the phone, I feel like it happens when ext4 is writing to nand.

The volume rocker seems a little buggy as well.

Also anyone else notice apps randomly opening in landscape mode and taking up to ten seconds to flip back to portrait mode?

GPS works fine in maps 4.7 but not in updated 5.0. Will removing this file help to get the GPS in 5.0 working?
[Epic 4G Android Development] mattallica76:
I'm using Maps 5.0 without any issues.
[Epic 4G Android Development] TheBurgh:
Thanks. I would love to update to 5.0 but it always hangs on the checking navigation availability. Stick with 4.7 until I can get it figured out.
[Epic 4G Android Development] mattallica76:
Did you try uninstalling Maps and then reinstalling from the market?
[Epic 4G Android Development] alexs5:
Everything with the rom is going great, only thing is that im having problems with recovery, after installing the rom i cant seem to be able to install any other zip file (for samsung widgets) i successfully did the EXt4 procedure and all but my clockwork seems to just not work i get an error like "E:Failure at line 3" when its starts copying the contents on the .zip file. Also im getting a constant "/E cannot open /cahe/recovery/log" while on recovery, the recovery is ver 2.5.1.0 even tough i did uptdated it to 2.5.1.2 in order to do the ext procedures, everything works fine except the recovery any help will be greatly appreciated.

On another news..... Awesome rom <3 it :D keep up the good work
[Epic 4G Android Development] TheBurgh:
What is the best way to uninstall it. I have uninstalled the update and reinstalled but had no luck. I have not tried uninstalling 4.7

Do I delete from system/app and install from market?
[Epic 4G Android Development] mattallica76:
Delete it from the system/app directory. Then reboot, and download it from the market.

Hi, I am fairly new to flashing roms. I have tried a couple of Viperroms and am interested in trying Quantum v2.1. I am a little intimidated by the steps going to 2.5. I read all the pages and saw the link in blue on page 1 for 2.5 and for 2.0. Did I miss it for 2.1? If I did, I apologize, if not, I would greatly appreciate it if someone would post the link for me or point my noob self in the right direction. Thanks
[Epic 4G Android Development] JohnCorleone:
Also, if I do take the plunge and try to step up to 2.5, I downloaded the DK28-EXT4Kernal-Final. I was a little confused if this included the 2 things I was supposed to add before flashing 2.5 or if I still add those 2 as well.

You need to be in CW 2.5.1.2 to flash your .zip files from now on. If you try to flash in 2.5.1.0 you will get the "E:Failure at line 3" error.

Great Rom!!!!!!!!!!

Just want to say that I had been using this rom since 2.1 and it had been working fine with no issues. I finally decided to upgrade to 2.5 today and use the EXT4 Mod and let me tell you..... My phone is flying. It is running so smooth, stable and fast that I can't imagine it going even faster. ( i'll still look forward to updates.. hehe). Thank you Dameon87 for all your work on this ROM. Loving it. Highly recommend everyone to use it... atleast try, and you'll see. For me the EXT4 mod along with upgrading from 2.1 to 2.5 greatly increased all aspects of my phone.

My phone crashed last night in a big way. Lost everything. Battery went low, the phone turned itself off. When I turned it back on, it went into a loop (I'm using the final kernel). Came home, plugged it in, and let it charge for a bit, and it would do nothing but boot into clockwork. Tried reflashing, didn't work, tried Odin, didn't work (eventually did), but man.... Oh, and why is Clockwork after you flash back to 2.5.1.0? How do I get it back to 2.5.1.2?
[Epic 4G Android Development] cjobanion:
Were you able to get past the 2.5.1.0 recovery screen? If so, what did you do? I made the mistake of flashing a .zip/addon while in the .0 recovery (later read that you have to flash everything after the ext4 in the .2 version - -doooohhh) and have done everything you have listed as well as trying to restore back to a .0 version back up.

Nothing. I formatted the sd card, odined twice with dk28, and the phone still returns to the .0 recovery and will not let me do anything. Any help would be greatly appreciated. TIA

EDIT: I also cannot get my laptop to recognize my phone anymore (device not found in ADB). ANY help from ANYBODY would be much appreciated.
[Epic 4G Android Development] bondosho:
The only way I could do it was, reinstalling the Samsung drivers on my PC, and then using Odin to go back to stock. But now, after I re-flashed the ROM, and everything seems to be functioning, when I go into Clockwork, it shows version 2.5.1.0, and I cannot flash anything. I want my Sprint apps back. I'm one of the 3 that like Sprint Zone, and Sprint Navigation.
[Epic 4G Android Development] jr_mfn_p:
This rom with the ext4 mod fly's. I've noticed a big improvement in screen scrollings and web surfing. Downloads also seem alot quicker. Nicely done.
[Epic 4G Android Development] Koadic:
Have you rebooted the recovery though CWM? While in CWM 2.5.1.0, 'Advanced->Reboot recovery' should take you to 2.5.1.2 where you should be able to flash zips again.
[Epic 4G Android Development] cjobanion:
I have Odin'd twice (successfully according to ODIN), my computer "sees" the phone through Odin, but not through ADB?!! Everytime the phone reboots, it loads into recovery and says:

ClockworkMod Recovery v2.5.1.0

E:Can't open /cache/recovery/log

Trying to go into "advanced" only brings me back to this again.

Trying to load any of my previous back-ups gives me the same message, while trying to reflash ANY rom gives me "line 3" and "line 2" errors.

Thanks in advance for any help.

Edit: I even tried Odin'ing back to an unrooted pit/modem hoping to end up with a stock, unrooted version that would remove Clockwork altogether, but that didn't seem to work either.
[Epic 4G Android Development] bondosho:
Yeah, I did, and it worked. A little bit of sleep, being patient, and a bit of reading go a long way (I had been up for 2 days straight, just could not sleep the night before). Sorry if I came across like a douche.

Everytime I go to advanced setting, reboot recovery to attempt to get to the newer version of clockwork my phone reboots and freezes at the Samsung logo.

So... Just wondering if anyone is noticing any speed increases with the 2.5.0 and the EXT4...

I have two epics, one of which is running the 2.1.0 and I'm getting around 2200 on the Quadrant test.

The second epic; with a fresh install this morning of 2.5.0 and EXT4 I'm only getting around 1500 on Quadrant.

Just wondering if anyone else is getting any better scores with the new versions.
[Epic 4G Android Development] miltownsho:
Thank you, that worked!
[Epic 4G Android Development] abmcbride85:
The scores above 2K are due to the laf fix. The scores you see with 2.5.0 are w/o "lag fix" because quadrant gives so much weight to I/O test.

Sent from my SPH-D700

Also don't base your opinion of a rom on benchmark test. Flash it and give it a real world try. My epic is so much faster than my friends Droid 2 and Droid X and my wifes evo.
[Epic 4G Android Development] rigg3d:
I have noticed a significant speed increase on my phone after switching to EXT4, Very noticeable.
[Epic 4G Android Development] edonnelly:
Forget Quadrant. You're in the perfect position to do so side-by-side comparisons. Run some different things simultaneously and see what kind of real-world difference there is.

I haven't seen much if any difference with ext4, but the only thing I can compare to is my memory. I'm keeping ext4 for now.
[Epic 4G Android Development] Squeaky369:
That make sense. Because I have the advanced quadrant and the I/O test gives most the score.

So I'll run them side by side with some other stuff and see. So far, it does "seem" faster. My wife has an evo so I'll see what the difference is.

Thanks!!
[Epic 4G Android Development] Koadic:
Regardless of what your trying to do, if you are in CWM 2.5.1.0, and have your phone formatted EXT4, then you will get those errors everytime. If you can't get to 2.5.1.2 by going to Advanced->Reboot recovery, then you need to Odin back to stock by using a full tar file, and not just the modem tar/bin that you say you are using.

To return to a stock DK28, with no root or CWM, use the full DK28 file thats 289MB found here: *OFFICIAL* SPH-D700-DK28-8Gb-REL.tar.md5. Upon confiriming your phone will now boot and is usable, then apply the one click root/cwm, boot into cwm and reconvert back to EXT4 (if you want) by following THIS post located in and using the files in [MOD] Epic4G EXT4 Support [Froyo Only] [No More RFS!][Updated/Fixed v1.3]

[Epic 4G Android Development] cjobanion:
I appreciate your response. Thanks.

I still have an issue, though. When I try to Odin this file, it tells me that the "SPH-D700-DK28-8Gb-REL.tar.md5 is invalid". I'm at a loss now. Is there another file floating around out there or do I just need to keep redoing Odin until it decides it is a valid file?!

I have Odin'd before a few times, so I am sure that I have done that right. I'm just frustrated with this "new" message.
[Epic 4G Android Development] Bobbywatts:
Delect the .md5 off the end of the file and you'll be good to go
[Epic 4G Android Development] cjobanion:
Un-F'n-believable!! Thank You!! After hours of searching, reading, Odin'ing, screaming, pouting, and even questioning my manhood (haha), I can't believe that I over-looked something that freaking simple.

As you suggested, I deleted the .md5 extension off the end and everything worked perfectly. Everything is "right in the world" now! My kids have actually come out of hiding now that my phone is alive again!

Again, much thanks to you and Koadic.
