[Epic 4G Q&A, Help & Troubleshooting] tydynrain:
I have indeed. That was actually the first program/script that I tried, and when it worked it did so beautifully, but often on reboot the apps stored on /sd-ext would disappear/be inaccessible. If anyone has any idea why the ext4 partition would not mount correctly on boot, let me know. I've thought that perhaps I should repartition and reformat, maybe with different block sizes (it's 4096kb at the moment).

The one thing I didn't like about Link2SD was the fact that it always had to be running in the backround, and that if anything went wrong with it (FC, freezing, data corruption), that the apps on the /sd-ext partition would no longer function or be accessible. That's why I originally started looking for a script. I wish data2ext/data2sd would be baked into one of the new EI22 ROMs...hint, hint. ;-)

USB & CMW NOT WORKING -Need to return to stock

Guys I have done it now. . I was rooting and ROMing my wifes phone without her knowledge, then had a brilliant Idea to update CWM to latest version. Tried Odin and discovered USB is broken, Tried to take it back to Sprint and they discovered ROOT and rejected me until I return it to stock. when I trie to load into recovery I got the image below, diligently I rebooted, reflashed. To know avail. What is a loving husband supposed to do?

I am running the latest ACS EPIC 4G ROM, nothing wrong with the ROM still works.

Problem:

1. USB does not work

2. Clockwork Mod Lost/overwritten

3. Need to return to stock to return to Sprint

4. wife is unaware of Mods, except to realize that phone is faster.
[Epic 4G Q&A, Help & Troubleshooting] tydynrain:
Hrmmm...OK. Having non-functioning USB and no CWM is a bit of a challenge. First of all, how exactly is your USB broken? Is the actual USB/charging connector broken, or is it a cable issue? If it is a cable issue, are you trying to use the stock cable (basically useless)? If the USB is absolutely unusable, then you have to get the stock recovery to successfully flash an update.zip file with CWM inside. To do this you need to rename the install zip for CWM and sign it with an app or a script. I know both are available, they just require a little poking around.

OK, here is a link for an app developed right here on XDA to sign update.zip files, and several others as well.

WOW...first off don't mess with a woman's phone unless she begs you to, then standard disclaimers about bricking and zombie apocalypse resulting.

Now

1. Are you sure the cable is good? Try another, try another port, try it with the battery and sd card out, try Heimdall....

2. Can you try flashing CWM 3.1.0.1 onto it? The flashable is in the stickied thread in Development. Pull out the sd card and get it into a card reader onto your computer to put the file on.

3. The tech was a jackass, they should not reject you because you are rooted if it is a mechanical failure. If you have no TEP they should charge you $35 to fix it.

4. Shame shame...keeping secrets.

Hi all... anyone else do the flash to RC1? Love it, but my Home key doesn't work... didn't keep my apps on the home page, no big deal... but I need the home key functionality. I have to back out of everything. Flashing back to 4.0.1 for now.

Trying to upgrade Clockworkmod and new CleanGB

I originally rooted with OneClickRoot which installed CWM 3.0.2.5. Then I flashed CleanGB b10. Now I want to upgrade to CleanGB 16 and the tutorial video said to upgarde to CWM 5.0.2.7. I installed ROM Manager and said flash ClockworkMod Recovery and now it says Current Recovery is 5.0.2.7. However, it will not boot into 5.0.2.7. If I press "Reboot into Recovery" in ROM Manager then it reboots and shows the 5.0.2.7 logo but then aborts and boots into CleanGB. However, if I hold the power button and say reboot into CWB Recovery, it successfully boots into 3.0.2.5.

My questions are as follows:

1) How can I fix whatever I did with CWM so the 3.0.2.5 is gone and it uses the 5.0.2.7?

2) Are the backups I made with 3x still going to restore properly on 5x?

3) Once I have the new CWM installed, I should be good to move the CleanGB 16 zip file onto my sdcard and upgrade from CWM, then restore what I want using MyBackup and Titanium. I hope I'm not missing anything: I've read everything I can find but it's a bit overwhelming and I'd hate to mess up my phone. Does this process sound right?

Thanks for any help and for all the great work you guys do here.
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
1. Simply go to the 5.027 thread in Development, download the flashable zip and flash. ROM Manager keeps it's own copy on your sd card whereas the flashable puts it into the recovery section of your phone.

2. They should provided you didn't rename them. Make another backup before flashing to be sure.

3. Yup.

double home screens!

Ok, i'm am on EI22 urban precision x 1.0 rom and samurai gen 1.2.1 kernel. My issue is that everytime I reboot I all of the sudden have a copy of everything on my main home screen (where it all should be) on the screen to the left of it. First few times i just deleted the other screen but then the next time i'd unlock my phone everything would be gone from the main home screen too! What can I do to stop this from happening? Any feedback would be very appreciated. I'm apologize if i'm not explaining this well. I found the situation difficult to put in words without actually showing whats going on.

Sounds like a buggy launcher. Try another launcher. I use Zeam because I like the scrollable dock at the bottom.
[Epic 4G Q&A, Help & Troubleshooting] SNYPE2K9:
Is there a reason the Glitch kernel is unavailable on the Epic? It seems to be the overclock kernel of choice for the other Galaxy S devices. It has a ceiling of 1.7 GHz, which would be a dream to benchmark on.

Does overclocking the CPU overclock the GPU? From looking into multiple Galaxy S phones (my brother is on Verizon) I noticed that the GPU scaled with the CPU at least in the Glitch kernel for the Fascinate. I haven't heard much talk of GPU overclocking elsewhere so I'm curious if the overclocks are increasing the bus speed and the GPU is just getting overclocked with the CPU.

The reason for these questions is I am just getting an Epic now. I have a plan I don't want to lose by upgrading so I have been buying phones outright for two years now. I was able get a mint Epic for $125+$15 shipping, so it seemed like time. I was having trouble with my Evo and I wasn't able to play the newer gameloft games, so I decided I needed a bit of a GPU boost. I just love to tinker with my stuff a lot and overclocking is something I do for fun. Though it would also help future proof myself just a bit. I have already had a Hero, Moment, and an Evo so it would be nice to find something I can stick with for a while.
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
Look into the IAP Samurai kernel in Development forum. He has OC up to 1.5G and increased frame rate to 72 fps.

As far as the Glitch kernel, I would check in with the CM7 crew in that thread in Development and see if there are any plans to port it.

is there a way to get higher bitrate video from the camera apk? i get the feeling the bitrate is set to 12 mb/s just because it is low enough for a class 2 microsd to be captured to. if i could throw in a class 6 card or so would i be able to edit a configuration file or something to capture at a higher bitrate or is there a hardware limitation that i would run into?
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
From what I have read the limitations to the write speed of the sd card is actually and android issue. Whether or not the bitrate of the camera can be sped up a little is way beyond me. So it may be software limitations to a point. Earthbound in the IAP Samurai kernel thread is doing work to increase the GPU speed and framrate of the display. He might be a good person to look into this.
[Epic 4G Q&A, Help & Troubleshooting] SNYPE2K9:
on the evo 4g there was a software patch to allow higher read/writes on sd cards, i feel like it was a rom thing rather than a kernel thing, though kernel would make more sense because all the drivers would be embedded in the kernel. i could talk to him about it and see what he thinks.

i could also probably see if i could do some research on the cmos sensor just to make sure there is no hardware limitation from the camera. i would have started there, but if something already existed i didn't want to go and reinvent the wheel.

i've been from the moment, to the hero, to the evo, and just today my epic arrived. i'm thinking i may have finally found a phone worth sticking with. perhaps i may even get into some development myself. i'm pretty well versed in linux, i'm not too familiar with c (i had the choice between it and java in college and i chose java) but i have a couple books. maybe if there is no answer i could try tackling this at some point. hardest part of developing is actually getting started XD

EDIT: So I used SD Tools to test my SD cards speeds (just to see if there was a software cap on the SD card speeds)

I'm getting 8 MB/s writes and 20 MB/s reads, I tested it three times since this is a class 2 and that seemed very strange to me. I also tested another sd card and got 6 MB/s writes and 10 MB/s reads. Does the Epic cache data before writing it to the SD card? Unless my Class 2 card is really this good (which I could test in Linux in a bit), then that is the only thing that makes sense. However, regardless of how this is happening. We have the throughput to capture at higher bitrates. Time to do more research.
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
You have to remember that we only have kernel source. The full tar.gz has not been released so the Developers are still limited to what they can do. It is possible that your class 2 card is better. The class is the minimum rating and when the chips get cut they are all different so you could have gotten one from the better yield end of the spectrum.

Compass installed upside-down?

It seems that any app that uses the compass shows the same issues - north and south are read fairly accurately, while east and west are reversed. I tried turning my phone upside down (so the screen was facing the floor), and held it so I could watch the screen as I pointed the phone in different directions - and the compass pointed in the right direction the whole time!

Either a software setting is reversed in my phone, or my compass was somehow installed upside-down... anyone else have these symptoms?

UPDATE: I may have fixed the problem by placing my phone on the table screen side down while performing the built in horizontal calibration in the display settings...

UPDATE 2: Not only is the compass now pointing the right direction, but apps that auto-orient when the phone is turned sideways, seem to be flipping much faster as well...

Hey I'm planning on rooting my Epic 4G (with DK28) using this method for mac:

http://xdaforums.com/showthread.php?t=808103&page=16

Could someone clarify some of this for me please?

Will this work with FroYo? I know it says it does, but it says a clockworkmod redirector is in the script? What does that exactly mean? Will I not have clockworkmod, and if so, how do I get it from the script?

Thanks!
[Epic 4G Q&A, Help & Troubleshooting] styles420:
It works just fine with Froyo. The redirector allows for proper rebooting into custom recovery, when using Rom Manager's reboot option or "adb reboot recovery"for example - if you don't plan to use either, having the script won't hurt anything our even be noticeable. The latest version of the one click root will also install clockworkmod automatically... Hope this helps
[Epic 4G Q&A, Help & Troubleshooting] || Acer ||:
Thanks so much for the response!

So if I boot into recovery mode, it'll go to clockworkmod?

edit: It worked until it said for me to reset desktop adb server and re-login.

How do I do this and what does it mean?
