[Q] how to root Sprint Galaxy 4g - Epic 4G Q&A, Help & Troubleshooting

I wanted to know what is the easiest way to root Sprint Galaxy 4G. I've tried the Super One Click Root App and it keeps getting hung up on waiting for device. I read that i had to download drivers, and i had a question about that. Is it referring to the device drivers for the phone once i plug it into the computer, or is there some other special drivers i have to download. I rooted my Eris, and want to root my friends Galaxy 4G, but it's not the same method. Also how do you get into recovery on the Galaxy 4G.
Please let me know the easiest way to root. He doesn't want a custom rom, just the root.

First stop is to the Wiki page. Then read a guide or two. Also utilize the search feature in threads and the advanced search for more broad searching.
You need the Samsung drivers for the phone. They can be found in the guides or directly off Samsung's website.

I've done that. I installed drivers. I followed step by step for the "super one click app" and it gets hung up on waiting for device. All the other methods sound confusing. One says to install drivers than it states to run "run.bat"! I don't even know where this is or anything.

The run bat is in the folder where you extracted everything, its a windows batch file i believe. Also if you are having issues with the computer seeing your phone try using different ports or even a different cable.

[Q] NB question... rooting & restoring factory rom

Pardon my ignorance -I have found some info from the forums as per the specifics of rooting and - im considering rooting my slide (as it seems 2.2 is never going to come) and go with CyanogenMod-6.1.1. Im never rooted a device but that part doesnt sound so hard (ive used linux before, etc) but my main concern question - is there a way i can make my own ROM code - or rather read out the rom code of my phone currently (pre-root), this way - should
a) i not have a good root experience (something not working right)
or
b) 2.2 comes out - via OTA
I can "go back" to my orinal rom code?
Moreover, is there a way I can go back and restore the original rom code that i backed up pre-root? I dont even know if reading out my own code can be done or if i must rely on some factory rom code available in some "slide bible" that has alluded me. Cant seem to find any slide rom bible as of yet.
Can anyone point me in the right direction or help ease my concerns...
Also ive read about "Titanium Backup" and 'Clockwork' and 'amon-ra' -- can any of these be used to backup current rom code prior to rooting ? or perhaps just after rooting?
New Bible:
http://forum.xda-developers.com/showthread.php?t=924793
Old Bible:
http://forum.xda-developers.com/showthread.php?t=704567
Old Bible definitely has stock rom. I glossed over the new one, didn't see them immediately, but I'm sure they're there.
Titanium Backup is for Apps, Clockwork and amon-ra are different types of Recovery. Within those two(or atleast Clockwork) you can make a "Nandroid Backup" which is what what you're looking for. It will backup your ROM/settings and stuff.
When you root you're going to be flashing an Engineer version that allows you to keep root, so you should make a nandroid of that. In the Bibles you'll find a link to a pretty easy root method:

Hope this helps.
i am new to this android stuff. but i flash or install new roms all the time to play with them, and in the old bible is the factory rom, i have tested it and gone back to factory and then rerooted just to see if i could. it is all possable with the little know how i have of linux.

Can some one please help
I have been trying to root my mytouch slide for quite some time. I have read post and followed directions on countless websites and even watched a few videos.
The first method i tried was the one where i had to go into command terminal, using sdk tools, and catch my phone in adb with "loop". This never worked because adb would only detect my phone when it was booted normally but when i would boot into recovery mode nothing would come up.
The second method was the one where i had to download a few files and put them in a folder in C:\ and from that directory in command terminal i had to run "my root" along with other commands that were supposed to push all the files I needed to my phones sd card. This didn't work because when i rebooted the phone into the bootloader the "ESPRIMG.zip" wasnt detected. So , im guessing, without that flashed first i cant install any other roms or upgrades.
I dont know what else to do and i would really appreciate it if someone would be able to help me finally root my fun
Sorry if i posted in the wrong spot or something.

If you want 2.2 OTA Go to CR's post in the development section and it should be one of the first. You have to root before installing as it is yet unreleased and it is unsigned. You can get all of the info on rooting/unrooting you need at theunlockr.com if you do not like root(which I highly doubt). There is an unrooting tutorial on theunlocker also.

that all sounds great but my problem is that i cant root my phone so i wouldnt be able to install that anyway
@han-shinibi
thanx again for those links
i used the second one and i got it to work.
At first i was having the same problem with the hboot not recognizing the ESPRIMG.zip but after reading alot of comments someone gave me the idea to backup my sd card and to format the sd card and try again. I backup all the zip files i had from the previous attempt and i formated the card from the phone and then connected it to my laptop on "disk drive" and formatted it from windows also(I used FAT32). I uploaded all the zip files and started the process all over again and it work this time(attempt #23). Now im happily running cm6.

Please help, trying to root a friends Incredible

OK, I am far from new to this. I have unlocked many WinMo phones and now rooted many Android phones. I have an Evo that was rooted with ADB back on 2.1 and have rooted many friends phones.
I am using UnRevoked and I have installed the HBoot Drivers. Now it says connected, then Pushing Recovery, then stays there forever. I even let it stay connected overnight saying that, I woke up the next morning with the same screen, it isnt doing anything. Is there a different, better method??
UnrEVOked is the 'best' method.
Recommend this: http://forum.xda-developers.com/showthread.php?t=855515&page=3
It will have the answers for ya.
Have you installed the usb drivers, back in the day that gave me the biggest issue.
Sent from my Redeemed Incredible using the XDA App.
after reading literally thousands of posts about unrevoked and finding that most issues turn out to be simple fixes or retries, and having used it myself w no issues, this is probably the most supported and used way to root...the gold standard...not to say there arent weird curcumstances it might not work... But its a total work horse ...if you have the skills to hack the hack im sure you could use the exploit and manhandle it... I usually type something wrong, disconnect at the wrong time, or execute "doooh!" Moments, and with the swiftness....after making sure the drivers are right, give the autopilot of unrevoked another go...its really the way too do it....
Sent from my ADR6300 using XDA App
If all else fails, if you know someone with a Mac computer that version of Unrevoked is simplified and you do not need to install drivers. Simply download unrevoked and root.
A friend of mine helped me root my Inc using the Mac version and it was a quick process. I have no idea how the driver/pc version of Unrevoked works as it has steps that Mac users do not need in order to root. I've been rooted for about a month with no issues yet.

I know it is possible to root using something like connectbot; I searched around here. I could only find some posts in HTC EVO Shift 4G where they had steps. Which would be the same, just the files you need are different (obviously)
Good luck, be-careful with this method too. Without a computer to use to odin with (if something goes horribly wrong). You're really risking things.
You can use the app z4root to root without a PC. However, it does not work on froyo 2.2

Rooted my phone but no rooted applications work

Hi folks,
I rooted my phone but no applications that require root access work.
I am currently running the 40.2 update on my verizon nexus.
I tried wifi_tether_v3_1-pre111.apk, rom tool box, root checker and root toolbox.
Rooted applications always say that my phone doesn't have root access or a kernel is missing.
When I do a fastboot oem lock, it shows that my phone is unlocked. I am quite confused as to why no programs that require root work for this phone.
Is their any programs out there that can verify that phone is rooted. Is their any technique other then what I tried that can verify it.
I am stuck and I dont know what else to do.
Is anyone else experiencing this issue? I cannot be the only one.
Simply unlocking the boot loader does not give you root. Check the stickies in the dev forum a guide

I normally would of, or but I answered your question on mobile as i was leaving the house this morning
Sent from a phone that is not running ICS
You need to install the root binaries to achieve root, look in the general thread and theirs a guide to show you how to root with superboot r3. Once you run it in adb, it will install the binaries and superuser apk. Then after go to the market and search busybox, install the app and let it install the busy box file.
It is impossible that your missing a kernel if your phone can boot. The programs you installed to check "root" are not compatible with the phone. For future reference, check the stickies in the general thread.

[Q] How to root my Galaxy Nexus but still get OTA updates from Google?

Excuse my complete noobishness, but can someone help me root my Galaxy Nexus but still get OTA updates from Google? I found multiple sources from here and a video from QBKing77 but nothing answer my question completely. I would be really grateful if someone with experience could help me by give me step by step instructions.
Thank you.
Rooting your phone does not disable OTA updates.
Why would you want ota if you rooted? Just flash a rooted version of the updated rom when it's released.

That's what I do. I don't flash ROMS, just use a few apps that require root. Install OTA Root Keeper from the play store to retain root. Run the app before installing any updates to preserve root. Then when you receive an OTA, install the update then run OTA Root keeper again to get your root back. Worked for me on Verizon Galaxy Nexus coming from 4.0.4 to 4.1.1.

Use the guide in my sig or stickied at the top of this forum.
Only change would be fastboot boot recovery cwm.img rather than flash.
Just root the phone, and don't flash any custom recovery, then download supercurio's OTA root keeper app from the playstore, to backup your root then enable root with the same app after you receive OTA

Don't use the toolkit?
Sent from my Galaxy Nexus
Why not?
The toolkit is SUPER easy.
Open the tool kit and the DOS window guides you through what to do, by typing numbers or letters to get the desired option. I can post the guide on when to boot in recovery mode and what the phone will do but as for the Toolkit, it's self helping. Just install it, run it and follow the on-screen instructions.
I do exactly the same as what you want successfully; I have a completely stock Nexus, but it's rooted for the use of some apps. The OTA update tells me when there is an update, I install then simply root again. I'd rather not have an app to keep root as that will be yet another app to clog up my phone's app drawer.
A lot of the custom roms aren't to my taste so I am happy to keep the stock experience
Will post again the steps when I am on my home PC.

simply because the toolkit is an excuse not to learn the FUNDAMENTALS of owning a nexus device.
what happens when something goes wrong? do you know what the toolkit is doing behind the scenes? most of the toolkit users DONT. there are more than enough 'HALP!1!1 I BriKt mah PhoneZ!1!!oneone' to prove this is the case....
if you understand what its actually doing, you understand how useless it truly is...
Well, for starters the "fundamentals of owning a nexus device" don't include rooting at all. I know many people who use Nexus devices un-rooted and are fine.
Plus, I'm more than happy not learning too much about it as I'd rather spend my time eating cake.
Remember, not everyone here is in to tweaking settings, trying different radios, resetting their phone every 5 mins to test yet another ROM.
Some people are more than happy with the stock experience but just want root. The toolkit makes that simple.
Secondly, if the toolkit was doing things behind the scenes, I'm sure someone would have found that out and reported by now.
Thirdly, how do you know custom ROMs aren't doing the same thing? They are far more likely to be able to phone home without the owner knowing.
Fourthly, I personally tried rooting the manual way but the one line help of "just type this" I got never really worked with my phone.
Fifth, I've used the toolkit on my own phone and my partners many times, I've seen nothing bad, no bricking.
Don't see why you're so against something which makes life a lot easier for people who aren't too sure how to root the manual way?

And yet another person who fails at grasping why XDA exists....
Sent from my Galaxy Nexus
Actually, I do. I understand why XDA exists but I also understand the multi-uses it really has.
Not everyone who comes here has a desire to mess with their phones all the time...
If you're not a fan of the toolkit, why not flame the developer?
Here's a short guide on what the OP wanted to do.
1) Make sure phone is up to date. Make a note of your software version - probably 4.1.2 or 4.2 and build number (mine is JZO54K)
2) Turn on USB Debugging (Settings > Developer Options > USB Debugging)
3) Shut down the phone
4) Start in Bootloader (power button + vol up + vol down)
5) Run the Galaxy Nexus toolkit
This is where we use the toolkit. Read the info and select your build number. The windows will guide you through what options you have. If you want to root only, choose that option. Go through the menus and type YES to begin.
6) Phone will restart
7) After ~160 seconds, ToolKit will restart to Bootloader
8) Phone will restart
9) Toolkit will finish rooting by pushing the files to the phone.
10) Phone will restart back to Bootloader
11) Finish - Confirm in ToolKit
See pictures for further info.

So does the person that thought I was saying the toolkit did something malicious... I never said any such thing.
Toolkits are pointless. It takes longer to learn the toolkit than it does the three commands needed to unlock and root a nexus. That's my ****ing point, yet this guy is going on about how easy the toolkit is to use. If it's so ****ing easy, why did you have to provide screenshots and instructions?

**edit**
i cannot believe that someone would actually think its NOT beneficial to understand the process, and rely solely on a toolkit...its amazing to think that there are people so wrapped up in their own little minds, that they refuse to take the time to learn to do things the right way and understand what they are doing to their device.
what happens when joe user, who only knows the toolkit, flashes a mod on his phone that was NOT intended for his phone/build/rom version, and he bootloops? he jumps on xda and posts a thread. HALP I JACKED MAH PHONE!!! how do i fix it with the toolkit?
please, for the love of tech, LEARN what it is you are doing. do us all a favor and help spread the KNOWLEDGE and stop with the damn toolkit. this website is designed for you to learn, not follow a damn prompt/menu to get instant gratification.

Don't use a toolkit. Learn commands yourself and you won't have to worry about what a toolkit is or isn't installing.
Sent from my Galaxy Nexus using xda premium
root toolkits are fine, if you already know what you are doing. the problem with root toolkits arises when a person that has no idea what they are doing uses them and messes something up, which happens often, just read all the threads that users start asking for help, that include the words "i used a root toolkit". you dont see any these thread with the words i used fastboot or adb. usually what happens is something simple gets messed up, then the situation becomes worse because the user didnt know/learn the basics, and messed something up after. this is the problem with root toolkits, they go around you having to learn the basics. then we get all these threads about "help, i bricked my device". just taking the little time needed to learn the basics prevent this from happening.
this is a nexus device, its meant to be able to root the device easily. this is the basic procedure.. fastboot oem unlock, fastboot flash a custom recovery, flash the su binaries or custom rom in your custom recovery, reboot. that is it. it takes me 3 minutes to do this. add on a little reading beforehand, and maybe itll take you 30 minutes. much better than getting lost after using the root toolkit, or even messing up your device messing with stuff that you shouldnt. and, occasionally, the root toolkit itself can mess things up.
btw, op, you can always install an official "ota" manually, without receiving it ota, and without having root too. also, if you flash a rooted stock rom(unmodified, only root), youll still receive otas
You can unlock and root without install a custom recovery. IF you don't install any custom recovery and leave the stock one you'll continue to receive the ota updates.
Bye
