New to E4GT Have a lot of questions about roms/kernels/flashing - Samsung Epic 4G Touch

Hello all. Just bought a Samsung Epic 4G touch on Sprint and so far I'm definitely digging the phone. I sold my beloved HTC Evo 4G (had a fear tears and memorial) and now am a happy Samsung owner. I've got to say out of the box the phone works with no issues at all. Currently on EL29 stock (Rooted) and have NOT accepted nor received any OTA ICS 1st or 2nd official OTA build. On my Evo I flashed soooooo many roms...anything from Cyanogenmod to a couple of the "3D" roms....had a blast and loved my phone. I am now looking to get experienced with flashing AOSP roms or anything for that matter....Kernels....Modems....and of course roms. It seems different from what I have read. I know on my Evo 4G I was running CWM and I could flash anything...anything Os didn't matter it would work fine. Am I correct in reading that once I flash either the manual Official upgrade to ICS I cannot downgrade unless I do it carefully so as I do not hard brick my phone? how about flashing ICS Or Jellybean AOSP roms...?

As far as I no, the problem isnt going from ICS to GB roms. The problem is with going from ICS to other ICS roms. It is called the EMMC bug, if I am correct. If u wanna go from ICS to ICS, you wud have to go back down to GB, then flash an ICS rom.
I believe that the Agat recovery potentially fixed this problem,but caution is still advised.
If u wanna read some of this 1st hand,which i recommend, u can go here or search around for the eMMC bug

ok So for example I'm running Gingerbread EL29, if I wanted to try out CM9 or CM10 ICS/JB I would be ok???

Yup, as long as you're using CWM 5.

ok Let's say I upgrade to Cyanogenmod ICS or JB and wan't to downgrade back to Gingerbread EL29 do I just wipe everything in CWM5 then flash like a normal rom?

I would odin back to EL29. Or use direct boot kernel. It only boots up to GB CWM and then flash GB ROM or restore GB nandroid. The brick bug is from flashing ICS to ICS or ICS back to GB. But agats kernel has a safe recovery to flash ICS to ICS. I do it all the time.

Bottom line is don't do a factory reset in recovery with CWM 5 or any of its variants. That's what can fry your emmc partition. Instead you can safely do a full wipe with Calkulins Format All Zip for the E4GT. It uses GB binaries so it's safe. There's a full wipe zip and a modified one that doesn't wipe your data. I don't have a link handy but it's easy to find with Google search.
Agat63's new kernels are safe to wipe with too. http://forum.xda-developers.com/showthread.php?p=28639835
Stay away from Rom Manager. Our phones are far different than your Evo. The recovery has to be baked into the kernel unlike the Evo which could apply a recovery on top of the kernel with Rom manager. Mobile Odin is my preferred method of flashing kernel tar files.

[Q] ICS w/ CWM question

Is there a current ICS leak that has cwm built into it after loading it now?
I am currently running Calkulins.E4GT.ROM.v2.8.1 with Rogue recovery...
Is there an ics i can flash using that recovery, and once done still have recovery?
Is that what this Rogue *Stock FB17* v1.2.1 (CWM Zip) is, from http://forum.xda-developers.com/showthread.php?t=1390393 here?
I dont ever want to touch Odin again, i seem to have problems with that.
I also want to be able to flash back to a stock backup if i need, so i dont want to lose my recovery ability.

Technically, not really.
The official way to do it is flash calks fb17, boot up, and then odin rogues fb17 kernel/recovery.
HOWEVER.... Once booted into calks fb17 you can download rom manager,
Flash recovery from there selecting sgs2 as the phone and NOT e4gt
Boot into recovery from rom manager
Flash Rogue's fb17 kernel/recovery
Worked well for me.
ics
There have been many many bricks when trying to flash from ics back to gb .. The data partition on several phones has been fried leading to unrecoverable brick .... so far most going back to gb from ics have been using odin to be safe .... dont touch the cwm touch recovery with ics .... it leads to bricks .... The safest so far has been odin a gb rom then odin cwm recovery and then run your nandroid from there ..Be safe
I am running the ICS FB17 pre-rooted leak and flashed the zip with rouge, it had the stock ics recovery so i went back to this page (http://forum.xda-developers.com/showthread.php?t=1342728) and downloaded the latest auto root and ran option D and the option A to flash the rouge for the FB15 modem.

If you are concerned about having to "touch" Odin again, then you shouldn't be flashing any of this stuff for now..

Can you elaborate why it is bad to flash back to GB through CWM? I've done it twice already due to overheating in ICS and haven't had any issues. I just want to know if damaging my phone by doing that :/

It isn't bad to flash back to GB through CWM per se.
It is bad to fake flash CWM Touch onto an ICS linux 3.0 kernel and do a restore or wipe. The combination of CWM Touch and the ICS linux 3.0 kernel has caused many people to hose their /data partition in such a way that even repartition using ODIN doesn't allow /data to be written to anymore.

That's the one people happen to have had bad experiences with, but the general issue is "fake/temporary" flashes which end up pairing recoveries with kernels they may not have been intended to work with or may not have been tested with, then trying to operations on your phone which may overwrite sections that are hard to recover from.
CWM Touch if integrated (ie repacked with) and tested with a kernel it appears to work ok.
Honestly, just take the time to get to know Odin... its really safe and useful when you invest the time (which is very little). and this is coming from a 'noobs' perspective. As for CWM i have used it as well (not touch) and been okay, but like everyone else has warned... be careful.

Gotcha, so my steady hawkin FB17 kernel/recovery should be good.

Is the Epic a fail when custom Rom installed? Questions? also can ICS be rooted?

Well new company gave me 20% Sprint discount and have become sick of my Tmobiles poor coverage. However I fear wimax might be sucky too here in Seattle. Anyway, long time member here and have been involved in the HTC Sensation and One forums. Both with very very stable roms and kernals.
I was excited to pick up a couple Sprint Galaxy epics and the guy at Sprint had his all rooted and claimed it was smoking fast.
However I came to this forum and see all kinds of complaints of loss of stability just from simple Root of the Epic? Also have not read any stable ICS roms and I have read all of the threads. Plus read this phone is very easy to brick under clockwork. With sensation we use Aroma and it rocks!
So before I move on, I am not looking to break rules on asking ROM questions. I simply would like some input on what ICS rom is stable and supported still as I see many devs have moved on the the sg3 here.
What kernal and radio or what you call modem is stable and how do you find what is for your phone match?
Lastly, what is safest way to ROOT and flash ROMS for this phone?
I did read the stickies but am still confused.
I may be just happy at first to simply ROOT and install the fix for Hot Spot Wi fi and go from there.
Thanks so much.
Not even sure if phones will arrive with stock ICS tomorrow or GB...

The SAFEST way to flash stock ROMs in case of emergency is using Odin.I've found both stock ROMs (GB & ICS) very stable, however I reboot my phone everyother day (windows habit).

First off thank you for your reply. Interesting, I have read ODIn maybe responsible for bricking many of these phones is that incorrect? Lots of what I found seeing the people are very unstable with the custom roms so far for ICS for this phone of course stock ICS will be here soon.is there the ability to just root the phone and leave the stock ics ROM and just run the sprint hot spot mod.

Odin never causes any bricks as long as the process is not interrupted. Most of the instability is caused by user error. From my experience, all fresh (by fresh I mean wipe data/cache and format system) custom ROM installs have been rock solid stable. Also, most network issues are fixed by updating profile/prl. Official ICS is already out, it is build FF18. Stock ICS will not normally have the hotspot mod. You will have to use a hack to install it yourself. If you want a stock ICS experience, use this odin package (reset user data) to odin your phone to pre-rooted FF18:
http://forum.xda-developers.com/showthread.php?t=1721229
And here is your hotspot hack:
http://forum.xda-developers.com/showthread.php?t=1760712
Nonetheless, I see no reason why you wouldn't just save yourself the time and flash a custom ICS ROM.
Imho, there isn't any ics custom rom as of yet that is 100% stable, glitch-free, and reliable. I would wait it out until more polished versions come out. If there is a pretty good one to try, i'd say the blu kuban.

So I just loaded the FF18 Full Restore and Samsung drivers as indicated in this thread,
http://forum.xda-developers.com/showthread.php?t=1670110
I also tested after unzipping to a folder and the ODEN program comes up waiting for me to hook up phone I dont have yet till tomorrow.
I also watched this video and it seems very easy to do if this is correct process,
http://www.youtube.com/watch?v=_IL21F8Gfbs
Still some clarifying questions,
1. If my new phone comes with ICS already pushed to it. Do I simply still install FF18 to get root for the ICS rom?
2. If phone does not come with ICS will this install ICS and Root?
3. Do I need to use this or Caulkins to wipe data first before I do this process on phone out of the box new?
http://forum.xda-developers.com/showthread.php?t=1670110
Also I am little nervous reading this post from SFHUB<, Is he saying not to do the above process thru the built in Odin recovery in the phone if it comes with stock ICS in it? What does this mean???
The Epic 4g Touch has a bug in it's emmc controller that can cause the /data partition to become inaccessible/unrecoverable sometimes thanks to the wipe process when flashing from ICS recoveries... DO NOT FLASH FROM ICS RECOVERIES!!!!
7/11/12 edit: In the FF18 source Garwynn has confirmed the presence of the offending code that triggers the emmc bug (http://forum.xda-developers.com/show...1&postcount=32) meaning that it will eventually be safe to flash from ICS as long as the offending code is removed by the dev of the kernel/rom...
- Please see this (http://forum.xda-developers.com/show....php?t=1525495) thread by xST4T1K which details how NOT to brick your device... It is slightly out of date but still very relevant... if you want a more technical understanding of what this emmc bug is and why this is happening you can see Sfhub's thread in general related to it (http://forum.xda-developers.com/show....php?t=1644364 ). The OP contains all of the information that our users have been able to figure out about this bug... Be sure to thank these people, as their hard work has made it exponentially safer for all of us to flash ICS roms on our phones...
-Every ICS rom will have a flashing guide in it's dev thread, its HIGHLY suggested you read and reread the guide for the rom you want to flash and follow it EXACTLY, taking the extra time upfront to fully understand what you're about to do will save you alot of trouble going forward.
-Put simply though you will always want to ODIN or Mobile ODIN (mobile Odin is an app made by the dev chainfire, available in the play store, that allows you to preform Odin flashes from your phone without using a PC) the el26 Gingerbread kernel/recovery and flash any ICS roms from that. NEVER FLASH FROM AN ICS RECOVERY, THAT IS HOW BRICKS ARE MADE!!!! Also do NOT use Rom Manager or Touch recovery!!!!
- Currently there are some ICS recoveries that are thought to be safe to flash from thanks to the work done on the emmc bug. If one of these is included in your rom it will be noted by the dev in the rom thread, however the safest way is still just to Odin back to el26 in order to avoid any chance of bricking!
Next, once I do this FF!8 and have root and ICS. If I want to dabble in custom roms. I am guessing they are installed by CWM from file downloaded to root of SD card like normal. I do not find CWM touch for this phone anywhere. I am sure I am missing it. It seems from reading the exploit in ICS kernal is causing the bricks. So I am guessing to use SF hubs or Claukins data wipe before loading custom roms. Are we beating to the same drum here?
Will correct radio or modem be installed automtic with FF18 or custom roms? I see many threads just on modems.
Thanks and thanks for the hot spot mod.

Thats what it seems from hours reading each ROM thread. Reminds me of the Sensation when GB and or ICS first leaked. Will most likely just root stock and go from there.
CWM is in the kernel. Current kernels such as chris41g's or AGAT's kernels have patched up recoveries that avoid the emmc bug, so they are completely safe. You should use calkulins format all before flashing a rom in CWM.
For odin, it wouldn't hurt to odin sfhubs wipe data/cache, but it's not necessary. As long as you use the reset user data odin package for FF18, it will take you to stock rooted FF18. Regardless of what rom your phone comes with, run that odin package. You don't need to worry about the modem either because it will install the latest one. Be sure to update your profile/prl in settings>about>system updates after.
If you want to try a custom rom, use odin to flash a kernel with cwm (agat's or chris41g's). Once you have a recovery, flash calkulins format all, and then the ROM of your choice. Modems are not installed through CWM rom zips. You'll have to flash a modem zip in recovery or odin a modem tar.

I was studying Sfhugs FF18 thread and it says I can do the one click root and then install option D and that puts in the FF18, with agats CWM. So is this more simple then flashing FF18 and then doing a flash for either chris or agat kernal with cwm?
Should I use Calkulins format before flashing FF18 from stock?
So when you guys flash new custom roms you have to flash current modem each time? or only if you want to have a more current one? Coming from HTC you only have to flash radio when its required to match a new base leaked. So little confused there too.
Thanks your help has been great!

I know I personally use Mijjahz's "GOODNESS" ROM and it runs smooth. Many mods and add ons with more added daily. I flashed agat's 2.2 kernel because I don't like the 2.3 that version 16.6.1 comes with.
I also flashed FF18 over my EL26 modem. Modems don't change between flashing I believe. Those you update yourself. A lot of folks stay on EL29 or find something that works perfectly in their area.

you're quoting some of my new user guide here, and i haven't updated it since the OTA came out so it somewhat overstates the danger of bricking (not a bad thing really, made you read, didn't it!?) which was much easir to do before we got kernel source, since then agat63 and chris41g have been killin it in kernel development since they got ICS source... their ICS kernels are safe to flash from and can be found in the dev section, if you're on the stock FF18 rooted with stock kernel i would personally ODIN (mobile or desktop) back to EL26, and from there flash whatever custom ICS rom you like, as far as I'm aware all of the roms come with a safe kernel these days but do be sure to double check and flash one if it does not... at that point going forward should you wish to flash something else you can just do it via cwm as per usual without having to odin back to gingerbread....do note however that you can't use touchwiz kernels with AOSP roms, there asr safe AOSP kernels as well however...
edit: oops, just noticed revamper addressed most of this on the last page, to answer another one of your questions though you can try as many modems as you like and decide which one works best for you, its varies phone to phone and area to area... the modem is not at all required to match the build number of the rom, (example: may people still use the el29 modem with ICS) you can use ANY modem with ANY rom
Ive flashed this phone hundreds of times. Put your rom and any other zips you have on external card. Then to do a full clean wipe go to privacy. then factory data reset then check usb storage. You can skip this step, but this is how to get it factory fresh. Download the el26 cwm kenal. Its posted everywhere. Next open Odin go to pda and select EL26 cwm kernal. Uncheck auto reboot. Have battery cover off! Flash kernal pop battery out when it starts to boot. or says pass. then use the vol up and power combo hold them down until boot screen pops up then let off. Next flash calkulins wipe all or wipe no data. . Never brick never fail. Then flash your rom and tweaks and be happy. Ive done this driving down the road its that easy. Laptop sitting in passenger seat with odin up lol. Plus i drive a 5sp full size truck. Flashing is easy. Follow directions. There is nothing wrong with this phone just read directions if your a noob. I,ll be making multi scenario flashing youtube movies soon. Like mobile tech videos does.

Can't install ICS from Rogue EL29?

Hi all,
I just got a replacement E4GT from Sprint, I had planned on staying stock but after the hardware issues of my first iteration of this device and the somewhat lackluster update, I decided to take control and root/flash.
I used to do this on the EVO but it's been a while.
so I followed QBKing77's videos to the best of my ability. I have Rogue Recovery installed (pretty sure it's the latest, I downloaded from the official thread and ran the exe to install less than an hour ago). It's doing NAND backup and recovery just fine, so I assume Rogue is working but I can't install AOKP or MIUI.
From the video, it seems like I use the zipped file on the phone's memory, do I need to unzip first?
Can I flash directly from a EL29 Rogue to an AOSP ICS ROM?
Use Chris 41g's EL26 CWM kernel for initial AOSP flashes. Though if your stock now are you not on FF18 ICS yet?
El26 rogue for flashing.

No, No rogue for AOSP. Custom CWM bricks. Rogue was the popular one at the time, pretty sure there was another one that was not working as well.
EL26 with bone stock CWM.
RainMotorsports: I am on EL29, I've had the replacement for 3 days and it has not updated. I could follow the manual update but I hear most people like to flash from GB ROMs because they're stable?
also, I'm sorry, I don't understand flashing kernels. Don't we have to flash an ICS rom before we flash a kernel? And I thought the AOSP kernel was stock with Milestone 6?
rovar: So should I Odin back to EL26, re-root and install a recovery? Does that have a better recovery?
I'm wondering if I should just unzip the files and try again...
You can flash the EL26 cwm kernel on to the phone as is. If its rooted sfhubs auto root tool can do it for you http://forum.xda-developers.com/showthread.php?t=1342728. If its not rooted you can flash the tar for it in odin. http://chris41g.devphone.org/index.php?dir=EpicTouch/Stock+Repack/EL26/
As far as FF18 goes the leak was the OTA you can NoData one click for an OTA like experience where things are not perfect or wipe the phone with full data. http://forum.xda-developers.com/showthread.php?t=1721229
I can approach the rom/kernel question from 100 angles. But you need a kernel with the proper recovery to flash the rom, when you flash the rom the kernel is overwritten with the kernel in that rom. To get another kernel you once again have to flash a kernel. I do not keep up with AOKP. CM9 since alpha 6 has a safe cwm5 based recovery and it + the nightlies use a repacked stock kernel. Chris 41g is testing some from source kernels for both, the AOKP one requires his version of milestone 6 and thats my extent of knowledge on the state of AOKP kernels.
AOSP roms flashed with EK02 through EL29 rogue brick. Chris41gs EL26 CWM has been the tried and true kernel. You could flash the kernel of a TW or AOSP rom, the phone will not boot until a matching rom is installed but we did the reverse (EL26 kernel while the rom was still ICS) all the time.
Thank you. I found a video that showed how to get stock EL26 CWM Kernel installed via Mobile Odin. I am trying to make a second backup because I'm not sure the Rogue Nandroid is compatible but it's having trouble making a backup from here. It seems that it's only recognizing 200mb of free space and I know there's a lot more.
It seems that the EL29 Rogue backup I made won't restore to the EL26 kernel/EL29Rom I'm now running. I'm going to delete the old backup and try to make a new one.
Anyway, sounds like I'm pretty close!
And I'm now running AOKP. Thanks so much! You guys were fast and helped a ton!

Nice. I bet the addiction is already setting in. I just went from CM9 Nightly 7-22 to an early 4.1.1 AOSP build back to TCP's 7-28 CM9 which i had no clue what to expect from but I am on it now. Must must must flash them all!
Edit - I just flashed FF18 forgot I wanted to PRL update and fix my boot image while I was at it.

I need help with my girls phone please

I have flashed a calkulin TW Rom on my girls phone a long while ago, it is android 2.3. She has been asking me to flash an ICS Rom on her phone or even JB if everything works. I just started reading around on here and it seems to have gotten very confusing with all of this kernel talk and everything. Can someone tell me if I can flash a updated kernel while still on this old Rom, and then backup this android 2.3 Rom, then flash an ICS or JB Rom? I need to knkw if she doesn't like the new Rom, will I be able to restore the old 2.3 Rom with this new kernel and recovery. Can someone explain this to me, or point me to the best thread to learn about this phone again. I'm used to HTC devices and they seem way less confusing than this phone. Thanks in advance.

An updated kernel? If you mean ICS or JB kernel you cant do that.. You can only use gingerbread kernels with gingerbread.. Now if you want to try some JB / ICS
Just make a back up of what you have... Grab your rom of choice
Wipe everything(its safe since your on GB), and flash your ICS/JB rom (kernels are included with these roms so no worries)
Now when you want to restore just go back into the recovery of your rom(whatever you flashed) and restore the calk rom.. It will be just like you left it

Ok, thanks for the extremely quick reply. I have also seen things about unsafe recoverys or something of the sort. I'm on a very old recovery on her phone. What would you suggest I update the recovery to before I do this? I believe it has the cwm rogue recovery on it now if I remember right. Thanks again.

If you are familiar with odin or mobile Odin.. I'd odin /mobile Odin the El26 from here http://forum.xda-developers.com/showthread.php?t=1662295.. Unless you are on el26 now? It been a minute since I been on GB
But ICS kernels are now safe (agats, kuban kernel) to flash from and restore your back up to GB
JB kernels are safe as well to restore your back ups /flash from
I never *flashed from a jb kernel tho.. I always play safe and mobile Odin el26 before flashing from a JB kernel

Just go to the Android development forum (not original development) there's a sticky there called kernel repository find any gingerbread kernel and as long as it's not rouge recovery you'll be able to backup her current ROM and flash any new one you want. I say avoid rouge because seems a lot of people myself included couldn't flash roms from rouge. And if you want to do jellybean sbrissen's kernel/recovery is safe to flash back any ROM as well. I did it last week

Switching to AOSP from stock JB

Hey guys, just got my E4GT yesterday. I installed the rooted GB27 via the one click method. Then installed kernel/recovery through mobile Odin and the tar from here http://forum.xda-developers.com/showthread.php?p=40549220
I am coming the Nexus S 4G (got the epic via a warranty swap) and a Nexus 7, so things here are WAY more complicated. I have been reading like crazy to get a grasp of the flow of how to do things with this device, but I keep getting what seems like either conflicting information or gaps in knowledge.
So what I want to do is switch to an AOSP ROM like PAC or CM, as TW UX is so not jiving with my nexus sensibilities. So since I am currently on all JB partition images I am to understand that I need to switch to a ICS modem. Now this might be a seemingly stupid question, but is there a perfered version of it? I see quite a few ICS modem and don't know to choose and nothing seems to give advice in this regard (at least that I can find). My only guess would be the largest number would be final ICS modem and thus should be the most stable/best available. Thoughts?
Then recovery, I see that the recovery I have installed is for only TW jellybean Roms. So I would have to flash another kernel/recovery prior to flashing my aosp ROM of choice. The GB - EL26 seems to be recommend from many sources, and I want to avoid the whole emmc brick mess. So is that the preferred recovery to flash from? And just so I understand, once I flash a ROM it will then inject its own kernel/recovery images correct?
So every time I want to flash a new ROM, I would start with installing that gingerbread recovery, then reboot recovery into that recovery, full wipe (factory reset,wipe cache/dalvik cache), flash ROM+gapps, and reboot. What about nandroid? Since I am switching recoveries so often are nandroid good across different recoveries? Or not? I am used to being able to have a few backups handy to always be able to get back to a working ROM.
Anyway, thanks in advance for any advice you have to offer. I hated having to ask these questions, but better to ask than end up with a paperwieght.
Your reading has paid off, looks like you got it down. FL24 is the newest ICS modem. EL29 directboot kernel is pretty easy to use, only problem is that it can't flash modems. But you can do that after you get AOSP booted up.
Nandroids are only good on the recovery that they are made on, but all the AOSP ROMs use the same recovery. If you use garwynn's v0.4.1 GB27 kernel it uses that same recovery as well, that's how I go about it. You'll catch on quick don't worry.
Search for Mobile Odin it will save you a lot of time.

I like things about both, mostly just the music on TW. But yeah, I usually stick with AOSP. I've got 8 AOSP ROMs in the Android Development section when you get around to it. Welcome to the madhouse btw.
