[Samsung Epic 4G Touch] themacs:
Have a Sprint SGS2ET4G (wonderful phone, came from an often doctored Spint Palm Pre+) rooted and loaded ZedomaxOverclockKernal (v4.1 I believe) via ODIN, and SetCPU to 1.4/400 Ondemand.

Two large issues thus far:

1. Battery life has fallen off a cliff! Went to bed with Juice Defender on and phone in airplane mode. Normally lose a couple percentage points of battery power, but I went from ~75% to 18%! Ugh! Something not right. Drain during the day is significant with pretty light use. Have to recharge midday.

2. Phone will not stay powered down. If I power it down (via normal/stock method - hold power button, select power off, shut down, ok) within a couple minutes it auto re-starts.

Any suggestions/guidance would be greatly appreciated.

Thanks in advance!

After flashing I am getting LOS multiple times per day.

I have to turn phone off and back on to restore service.

Any ideas?

Same here... I got used to it by now, this phone boots up mighty fast. :)

I tried Airplane mode but no dice.
[Samsung Epic 4G Touch] Noan21:
Quite often my phone is going into roam, won't come out and I can't get text or phone calls while I'm roaming.

I go airplane mode and go out and I have no service after that.

Reboot the phone and it's good for an hour or two.

I remember seeing something, I thought in this thread about needing to go to a terminal and get a code then change some setting on the phone?

Is that correct is there another fix for the problem I'm having?

Thanks!

Edit: nvm Found it http://xdaforums.com/showpost.php?p=17703908&postcount=11

IDK if that is going to fix my issue or not but going to try it.

Edit2: That did not fix my issue the phone still goes into roam, and I am unable to make or receive calls or send or receive texts.

Arent those from the gsII original kernel so they wouldnt work??
[Samsung Epic 4G Touch] zedomax:
thats what i was wondering.

---------- Post added at 09:48 PM ---------- Previous post was at 09:40 PM ----------

actually this could work, because the GSII boot.img and recovery image both work, my phone boots, just don't have network/data, someone just need to repackage it with samsung source kernel, I am gonna try that right now... wish me luck caz i dont want to brick my phone twice in two days.
[Samsung Epic 4G Touch] bubby323:
Don't do that... /facepalm.

The initramfs has to do with the service you receive. It has network references that are CDMA and Sprint specific.
[Samsung Epic 4G Touch] zedomax:
I don't get why initramfs isn't included when compiled???
[Samsung Epic 4G Touch] deano0714:
And now he cant flash to stock kernel cuz we dont even have it yet... Isnt the recovery kernel seperate from The regular kernel? Or am i wrong? If so someone could flash juust the recovery and then flash su.zip and get the stuff we need... But im so guinnea pig, ill leave that to somone else..
[Samsung Epic 4G Touch] bubby323:
That would be a more appropriate route like I said before you need root to pull the stock zImage to be able to pull the stock initramfs and compile kernels.
[Samsung Epic 4G Touch] zedomax:
is initramfs universal? Can I just add that to kernel myself? Or is it specific to the device?

---------- Post added at 10:07 PM ---------- Previous post was at 10:06 PM ----------

How to you pull stock zImage???
[Samsung Epic 4G Touch] bubby323:
Because the initramfs can be edited for custom bootclasspaths, root privileges, and custom kernel names, ect.
[Samsung Epic 4G Touch] zedomax:
How do you pull stock zImage???
[Samsung Epic 4G Touch] bubby323:
You use a binary called dd on the phone, but you can't without superuser permissions, so you need root first of all. Try flashing clockwork for the GSII using Odin, if you are brave enough, then su.zip like a previous user mentioned. That might in fact let you achieve root considering if the partitions are the same locations and everything then I can walk you through pulling the zImage on the phone.
[Samsung Epic 4G Touch] deano0714:
So was i correct when i said the recovery is seperate from the stock kernel?... If so someone else needs to do it other then zedomax as he alredy has the gsII kernel and not our stocl one..
[Samsung Epic 4G Touch] spdwiz18:
hypothetical.

if adb can find recovery (adb reboot recovery) shouldn't fastboot be able to flash CMW to the recovery partition like with a nexus phone. we know the bootloader is suppose to be unlocked (fastboot flash recovery recovery-clockwork-3.1.0.1-crespo4g.img) just a thought. I might be way off.
[Samsung Epic 4G Touch] zedomax:
i have root, give me the commands, I've pulled 5,6, and 9 already.
[Samsung Epic 4G Touch] bubby323:
No, fastboot is for Google specific branded devices. (Nexus) Clockwork would be the way to go here..
[Samsung Epic 4G Touch] deano0714:
Im pretty sure those files are useless because they are from the gsII kernel not ours.. Also untill we get the kernel pulled your phone will not have a cell signal cuz you cant flash the stock kernel back :/
[Samsung Epic 4G Touch] bubby323:
But you are using a SGSII kernel to get root which there would be no sense in pulling since it's NOT for the Epic Touch.

---------- Post added at 04:18 PM ---------- Previous post was at 04:14 PM ----------

You should just be able to use the kernel you are using from the GSII with root, and then boot up into clockwork and flash the su.zip and flash back the stock kernel. That solves root for you, but not for everybody else until we have the stock kernel pulled from the device which is impossible without root.

Does anyone know how to mount these images on linux?

this isn't working for me:

[Samsung Epic 4G Touch] bubby323:
The source AND the initramfs MUST be from the Epic Touch and NOT the SGSII.

Ok, then try other ways to get root. Try a one click from the Epic 4G.

There is no point in mounting them, and linux doesn't have native yaffs support built into the kernel unless you add it.
[Samsung Epic 4G Touch] Epix4G:
Z4 don't work butI didn't think it would
[Samsung Epic 4G Touch] bbedward:
You need a destination you're mounting it to

mount -o loop image target

like mount -o loop mmcblk0p5.img /mmcblk/05

---------- Post added at 10:56 PM ---------- Previous post was at 10:48 PM ----------

this could work, i just built initramfs from samsung sources, i was thinking, why on earth samsung would give open source that couldn't compile a fully working kernel by itself??? doesnt make sense that we'd have to pull it from stock kernel.
[Samsung Epic 4G Touch] bbedward:
Are you flashing through CWM? If so why not just use an AnyKernel type of template which has all the scripts you need built into it (just need to change the paths for zImage/modules/etc if they are different on the samsung.

I know it builds the initramfs for you :? and without any modules, the initramfs will be very small. The more modules you use the bigger.

idk if the samsung does it different from every other phone, but usually the only deviation is the location of the modules or boot image
[Samsung Epic 4G Touch] zedomax:
ok, now i just want to have a bootable kernel, that should be possible with initramfs from the gs2 right since my phone is booting??? Trying that now...
[Samsung Epic 4G Touch] datajosh:
Not sure if you're still working on that but I think it's supposed to be bigger than 50K, there's some initramfs stufffrom the SGS2 on this git if it helps any.

OK unfortunately I left my notebook at work and it is killing me that I can't get in here to try and help at all. I am no dev and am pretty new to this but what about this idea. Is the recovery partition different from the original epic to the epic touch. Here is what I am thinking. I have a Odin flashable tar for the Epic which includes the recovery.bin which is clockwork. Could you pull everything except the recovery file out of the tar. Flash it with Odin and get CWM? I wish I had my computer because I would try it.

[Samsung Epic 4G Touch] bubby323:

Why can't zedo insmod?

Sorry if this is annoying (being a newbie and all), but I noticed when building the kernel that the wireless and bluetooth are built as modules. So why can't zedo do

insmod dhd

insmod bthid

assuming he has those installed from the kernel build? Are the kernels incompatible?

I thought initram was just a temporary root fs to get things going. The modules should be installed on the fs, right? Or am I being misled by my desktop Linux experience?

Sorry in advance for the ignorance :D
[Samsung Epic 4G Touch] zedomax:
You know what that COULD be the key, there's an option to build the modules as modules or built-in, I have it all as built-in, let me try compiling as modules then insmod them.

You need to add every module the kernel builds to the initramfs, it tells u where the modules are after building. There's useful scripts for building these automatically (make-kpkg , etc)

On desktop you do modules_install and it	insmod's them automatically from /blah depends on distro
