What do I need to know about rooting an Epic 4G?

Work just picked up a bunch of Epic 4G's. Battery life is horrible. I want to calibrate my battery so I'm wondering what the best root method for these phones is.
I currently have Gingerbread 2.3.5 on this phone.
I've also got a Epic 4G Touch, that had one click root, looks like these don't?

There is no one-click solution for Gingerbread. You would have to Odin EC05 for that. Here is how to root Gingerbread stock phones:

Is there a un-brick method is something goes wrong?

If you mean sponge or soft-brick then yes in the Stickies at the top of Development. It requires using Odin or Heimdall and your current data will be lost.

There is a more "pain in the ass" process of rooting your phone if your already on gingerbread. I will link you to some videos that should get you going.
You WILL need ODIN to get rooted. There are ways to root your phone without it, but ODIN makes things alot more simple. ODIN will become your best friend, trust me.
First, you will need to follow this step...

Once you have done that, you will need to move onto this step...
http://www.youtube.com/watch?v=jWOLEXqAeCc
Of course, use the latest version of ACS Recovery, which can be found on the link to that video.
Once you have completed those steps, you will be rooted, running ACS Recovery Version 5, or ClockworkMOD Recovery 5.0.2.7
Hope this was helpful.

If you run into trouble like it gets stuck at the Samsung screen for more than 5 minutes, you can return to Froyo stock and OTA back to stock Gingerbread and try again. Here is the thread for that:

You can also PM me with questions once you get started.

I just flashed my first ROM (CleanGB) on to my Epic4G and reset the battery statistics. Along with using TB to freeze the DRM and SNS apps, I'm seeing great battery life. Thanks to everyone who contributes to this site!

Its not hard hahaha that's what I'd tell you anyways its really simple if you can get Odin to com its all downhill from there. Just thought I'd give you some encouragement since you've already been given directions. Never be afraid to root the epic is nearly impossible to brick.

Oh big one don't use the stock USB cable if you have one use a blackberry one learned that the hard way.....

My stock cable works fine. Grab Odin as it is an all purpose life saver. Are you planning on rooting and using custom roms or just using root apps?

The stock cable worked fine for me when I rooted my Epic, too. I used the Rooting EI22 Gingerbread Instructions from Android Central, and fortunately it went very smoothly. It was my first time rooting my phone, so I was glad I didn't have any major problems. As noted above, you'll probably want to substitute one of the newer custom recoveries in place of the one in those instructions though. I thought I'd offer these text instructions (with screen shots) as an alternative to the videos posted above.
Regarding use of ROMs or just root apps, I actually rooted mainly to get the GPS and silent camera fixes. I'm probably going to want to use a custom ROM though, but am still currently on stock rooted EI22 (with those two fixes applied). I'm slightly concerned about getting all my apps and data back if I install a new ROM. I've got backup apps (Titanium Backup, non-pay right now, and MyBackup Root), as well as a nandroid backup from what I've read advanced restore of just data is possible, but don't really know what's the easiest/smoothest way to get things back. I might want to go with the MostlyStock ROM, since it probably changes the least amount of stuff, or something with a non-wiping version (I've seen at least one, but forget which it was offhand). Tips on how to make moving between ROMs while keeping apps and data easy to restore would be appreciated. Thanks!

Your stock cable will.appear to be ok, but once you turn your back, it will brick your epic. Trust me. Been there done that.

The hardest part, for me anyway, is picking a ROM to stick with. Right now I'm addicted to trying out as many things as I can. Right now I'm running ThunderHawk but I'm sure that will change soon. I will tell you I haven't have a lot of luck with ROM management tools. ACS updater doesn't seem to have anything new, installs from ROM toolbox don't seem to work, ROM manager has worked the best for me so far.

Get a BB cable trust us when we say your stock one will go south on you at the most critical time! I use my stock for charging only. I have read many of stories on here where the issue was the cable. If you don't have a BB cable laying around check amazon out $1.97 plus shipping. I picked up 4 a few months back I keep 2 at home one in work and one in my laptop bag.

[Q] Motoblur'd rom update and issues

Hello,
I am considering updating my gingerbread based ROM on my old EVO 4g (I am currently running Cyanogen mod 7.1)...
Its been a very long time since I've flashed a ROM to my phone, but I have been wanting to upgrade to an ICS/JB ROM for a while because (amongst other things) I hear that these android 4.0 ROMs are better when it comes to battery life.. As you can probably tell, I am not one of these folks that re-flashes their rom every week so I may be a bit rusty with this and I am a little bit intimidated. While I would like to try something new I also am a bit worried that my lack of experience may cause me to make a mis-step and mess up my phone..
The ROM I am looking at right now is the new release of MotoBlur'd, found here: .. I understand that this ROM is based on CyanogenMod 10, and since it seems I cannot get a version of the raw CM10 directly to install on my phone, perhaps MotoBlur'd is the next best thing...
But before I open up this can of worms and go off and wipe my phone and flash this new rom, I had 3 questions which I hope someone with experience can answer
1) All other things being equal, would this actually help with the battery life, over the Gingerbread based CM 7.1?
2) Is it still the case that Netflix and other video viewing apps do not work with this (or any other ICS/JB) ROM?? They mention it in the android dev thread, but no one has confirmed that these things work or not work.
3) Do I have to peroform any extra steps or install anything else (other than what is shown in the instructions) to move the phone from CM 7.1 to the latest Motoblur'd ?? For example do I need to install an ICS based ROM first before JB? Or can I just flash directly to this ROM??
Hopefully I can do this without causing too much damage or requiring too much help from the users in this forum... Of course any advice or suggestions anyone can give me would help...
Thanks

Excellent guide, Hipcat... I think this will really be helpful to me... As someone who doesn't do this all the time, it can really help to have a guide like that to cover all the bases.. I know we are supposed to try to search for the stuff that we need to know, but sometimes its hard to know even what we need to know, and sometimes the multitudes of information we find is contradictory or out of date, so this really helps..
I found a broken link on it, so I posted that as a reply in your thread (I hope thats okay)...
I think I may just stick with my GB based rom, as much as I would like to monkey around with ICS or JB.. I guess I don't see the sense of switching if it won't help my battery life and if it will prohibit the use of video playing apps (which, I know, suck a lot of battery)..
The biggest problem for me is the battery life (I found several contradictory explainations on how to calibrate the battery, I will try the one found in your guide next), but mainly I believe my problem is that I have too much garbage loaded on the phone (not reloading after a year and a half can do that), and a lot of stuff loads in the background so that is probably affecting my battery life.. Also I don't think I am using the most up-to-date radio, which is probably causing the most battery drain of all... So I am going to try the following...
1) I am going to (actually I already have) upgrade my radio to 2.15.00.01.15
2) As per your, and honda's suggestion I will try to update my recovery to smelkus 4.3 (I think I am using clockwork recovery right now, although I am not sure if that is the same thing or not)..
3) I will try to re-format and re-partition my SD card and attempt to install A2SD so I can have more room for apps (can I use A2SD with CM 7?)
4) I will wipe everything, and reload to CyanogenMod 7.2 (perhaps this will work better than 7.1) and reload about half the apps I have on there now (only the stuff I am using now)..
If battery life is my main concern, is there a better ROM I should be using??? I picked CM in the first place because it was an AOSP (no frills, no extra garbage) ROM, however I haven't been able to update my PRL (havent ever updated it, probably)...
Thanks again for your response... You and your guide have been quite helpful...

Yep, I fixed that link and what you said is why I wrote that guide; because searching can be a real pain in the @ss sometimes. It's like a teacher telling you to look up a word you can't spell. Well how do you search for an answer if you're not really sure of the question?? lol

You cant update your PRL on any non-stock rom. It has to be stock for you to be able to do that

Well if battery life is your main concern I always suggest a good sense 3.0 ROM. If you are worried about bloat that can be removed. If you want I can hook you up with a rom/kernel combo with everything you want.
When I am not testing or making a new rom I use sense 3.0 and can get 8 hrs of heavy use on stock battery. Thats netflix with 3-4 hrs use plus web surfing and calls during the rest. On my extended battery with light use I can get 4+ days.
If you would like to try my rom pm me before you partion your sdcard. There are certain things you need to do for it to work right.

Perhaps I will go to stock and try to update the PRL before I go ahead and update the ROM to custom... However, this Evo is on Boost Mobile (not Sprint) network, so I am not sure how to appropriately update the PRL... Should I just update it as if it were a regular Sprint Evo 4g or does it matter?

Umm updating prl only requires the *228 call from the phone and it works on any rom. Now to put a custom or older prl it takes a bit more. Updating your profile now that I do believe you have to be on a Sprint rom but I don't have Sprint so I can't say for sure.

Never heard of that *228, so cant say anything about that
Updating profile and prl I've always seen and heard can only be done on stock, unless you use this ##codes apps I saw somewhere....

The ## codes only work on the sprint roms. To change prls on AOSP roms you need a windows pc with qpst setup and prl files on the pc. Then you have to enable diagnostic mode through adb or a terminal emulator. There is a thread here on our EVO forum to do it. I will bump it so you can check it out. It sure beats all the backing up and restoring to do it.
Edit: I bumped it. It is in the dev section.

Yeah. Theres an app that uses scripts to emulate the ##code functions.

Really? I can't believe I have not heard of that till now. Do you know what it is called? I would love to check it out.

Found the thread, thanks!!
Now I just have to figure out which PRL file to use for my Evo on Boost, and where to find it (I think this is what stopped me from updating the PRL before, not knowing if I should use a sprint PRL or something else)...
Edit: I did find this thread regarding boost PRLs on EVO
And if there is indeed an app that emulates the ## commands, I would like to know what that is...
... TPK2013

Heck if your on boost you need a boost prl. You can Google boost prls and find dozens of them. I would suggest using the latest one. Just dial *228 and it will update your prl. After it finishes reboot your phone. It is really that simple. I do it on my cricket flashed EVO but it works for every service provider.

[Q] I Wanna Update To JellyBean.. But How??

Hi guys..
This is my first time on this site. I dont know why I never found it sooner. Anyways. I have a Sprint Galaxy S2 Epic 4g Touch. I am currently on the fi27 I believe & I am rooted.
I would like to update to the JellyBean.
First off, can I go to JellyBean from the fi27, or do I have to go to the Fl24 first, then to JellyBean?
Do I have to unroot, before I do anything?
I hope I am asking all the right questions. I really have no clue what I am talking about. I had my friend try to explain it to me, but didnt work very well... My head isnt right at times. I have a brain tumor, so sometimes things are hard for me to comprehend..
So if someone could tell me what I need to do in order to get to JellyBean, from rooted fi27.. I would appreciate it.. Or if someone can guide me to the correct post that I would need to read that explains it..
Just anything to help me get to JB, & whatever Files or programs I need or whatever..
Really appreciate your guys help!! Means a lot...

Rwilco has made a compilation of the stock roms (http://forum.xda-developers.com/showthread.php?t=1903252), which include Official JB Builds. When you feel confident about moving forward, you might also want to look at some of the other non-stock roms too. Good luck in your flashing!

To go from ics to jellybean flash in odin a one click for a jellybean rom. Super easy to do take a look at some stickies for guidance. Rwilco has the one clicks for you.

I am rooted. I said that in the first post.
I have no clue what an Odin is or a one click..
Like I said, I have never done anything like this before. I got my phone from a friend who had rooted it before I got it.
I apologize for my questions. Having a brain tumor messes up my head at times & things are hard for me to understand. I am sorry.
Can someone maybe post a link to the page or the file that I would need in order to get to JellyBean..
I am not on ICS. I am still on FI27
Can I go to JellyBean from FI27, or do I have to go to FL24 first?
Can I just flash to JB from where I am now, being on FI27 & rooted or do I have to Unroot first.
Nobody answered my questions..
Or If you did, I am sorry, but I dont understand.

Click on the link for GB27 root/restore and download to your PC.
Once its DL you need to extract files. Right click on your screen and make a folder gb27...then click on the DL gb27 and extract... Click to select where to extract too then select that folder you just created.
Once it's done double click until a screen pops up that says something like root/restore gb27. Boot to DL mode (power off the hold volume down and power at the sane time.. Then select volume up) and then connect to PC. Once it recognizes your device...yellow light...click start and then let it do its thing till the green pass light happens then your phone will auto reboot and then set it up.
I know this sounds like a lot. While you're DL the one click at this link watch qbkings video and it will all make sense I swear. He makes it very very easy.

grab the restore version of the one-click...being its ur first time on jb.. this will wipe ur phone data..so back up anything u need...but i definitely advise using restore version ...this will also create the correct system partition for jb on ur phone....and as stated above, Watch the qbking video...it is a great resource.....Good luck..

[Q] SPH-L710 C-Spire SoftBrick Help?

Hello new to the forums. I have been rattled once again by the s3. Finally a problem I haven't really found too many solutions to and plus don't want to increase my chance of completely destroying my phone. Now. I have a Virgin Mobile phone in the US. Was on 4.1.2 but to flash to cricket I was trying to downgrade down to 4.0.4 from JB to ICS. Pretty much during this process not doing my homework I used odin and put the phone in download mode and figured oh Sprints rom should work since SPH-L710 is the same model and completely being wrong. I have been searching around google because I am soft bricked. Here is my assumption of soft brick. When Odin finishes the screen goes red stating the recovery files cannot be found and it wont read my sd card. Still able to go to download mode but not reboot mode. Hence, Soft Brick. Been trying to get out and recently took off a sticker seeing C-Spire. Now I remember seeing this while I was reading my XDA forums so I figured why not. Found some youtube videos googled and fond J7 for C-Spire. So close, but the link didn't exist or something. So... My conclusion finally made an account and finally asking for help the correct way. Please provide links and comments to help me out here would love this s3 back on track. Hope I followed the rules. I did honestly search the forums one had c-spire, but link was dead. My luck man. Thanks in advance.

Wanted to also add. Maybe with this I wanted to for a while, but never had the clear instructions on this nor want to repeat the process of screwing up my phone AGAIN after fixing it. Any good ROMs for the s3 C-Spire SPH-L710? For Example, Would love to use that multi-window with anything and I tried pacman not loving the whole ics not using the home button preferably JB I think which is stock whatever is stock. I loved the XMT launcher and the whole PIE thing. Just let me know guys. Ahead Apologies for the noob questions if they are.

this help http://www.sxtpdevelopers.com/showthread.php?t=55
you should beable to flash that. then just let the phone update.

Still trying it out at the moment just downloading it, but if it does fix this and so on whats some good roms for the C-Spire or im presuming this does not ever fall in the catergory of sprint but cspire yes?

I don't have the c-spire, but once you flash the stock rom from the earlier post, you should be able to root and set yourself up with XMT and pie controls on the stock rom. They are stand alones and you can add them yourself, without looking for a custom rom for it.

just found my sprint s3 rooted w/4.3 wicked project

i just found my phone while moving.. charged it and forgot how cool all the mods were.. was gonna give it to my daughter with the pink theme. but then i started to check on everything and noticed a bunch of apps dont workl. tried updating some of the ones i could. but phone really started running slow. i know it was the last version of jellybean. so i want to update phone and get her a different rom.. but it has been awhile and i cant find original tar file. ive been looking through posts in development and found a kitkat one,but it says to update bootloader first. so im guessing that it is just the firmware. i need the whole stock file.. it should include the bootloader in there right? also i tried to update through flashfire but says my supersu isnt new enough.. cmon 7 years old isnt that old.. sorry.. but i really havent done this in awhile. if i uninstall supersu. then redownload it from playstore will it be updated? i think its built into the rom though. does that mean i gotta extract from system apk? ugh... this is kinda fun messing with this thing all over again. she might not get it.. jk. just want her to be able to use without any issues. would be nice if it stayed roooted. then i could change themes and stuff for her.. but if not stock it is.. she just turned 10.. so this will be her first phone...help would be greatly appreciated. thank you for your time in reading this long post.. sorry. Could def use some help trying to get this running right.
