Problem flashing CWM Recovery into Sprint GS2 - Samsung Epic 4G Touch

I was able to use Odin1.81 to restore the stock ROM (2.3.4) with root to my S2. Everything was good. Then I wanted to flash CWM Recovery. I tried two methods:
1) Installed ROM Manager from Google Play. Install CWM Recovery from there. Device selected as 'Epic 4G Touch'. This didn't work after reboot. Instead of entering CWM Recovery, the device went to 'Android System Recovery 3e' menu. It seems that Android has some built-in protection system from being flashed.
2) Restored stock ROM again, then flashed CWM Recovery 5 from Odin1.81. Now I could enter CWM Recovery, but I noticed the power on logo changed from "Samsung Galaxy sII" to "Samsung Galaxy sII I9100". A yellow triangle with an exclamation symbol appeared in the center of the screen. This bothered me a lot.
Does anyone know what correct steps should I follow to root my Sprint S2+install CWM Recovery?
Thanks in advance.

For number one. NEVER use rom manager like they brick our phones.
Use sfhubs el29 one click.

Use sfhub's auto root utility or download and flash Agat's safe kernel + recovery (which can be done through ODIN).
Then use Triangle Away to remove the triangle.

OK as was mentioned DO NOT USE ROM MANAGER! Unless you want a pretty paperweight.
Use sfhub's one-click(s) to add stock+root. You can use either the EL29 for GB http://forum.xda-developers.com/showthread.php?t=1433101 or FF18 http://forum.xda-developers.com/showthread.php?t=1721229 for ICS.
Then use sfhub's Autoroot to add a CWM recovery [either Rogue for GB or Agat's for ICS] http://forum.xda-developers.com/showthread.php?t=1342728
Find and follow the instructions. They are very detailed and precise.
I would also HIGHLY recommend doing a whole lot of reading. Read the stickies, read the OPs and the follow up posts too. A little time and patience will bring rewards. Haste and carelessness will surely kill your device.
Good luck.

Thank you, daniel4653, garwynn and leaderbuilder. You are all very helpful. I am going to try EL29 and Autoroot script.

Rooted but can't install rom

Okay just rooted my galaxy s 2 with the auto root, I want to install roms using rom manager but sometimes it will rom manager has denied super user permission but other times it will not say it all and it will download complete I hit install rom wipe everything then a triangle with an exclamation mark in it and the android dude on the side pops up and stays there, I take the battery out then put it back in and it takes me to the recovery system but it only says reboot now, apply update, wipe data, and wipe cache with the triangle with an exclamation mark in it and the android dude still showing behind it. Any clue to what can be wrong?
Sounds like you haven't flashed a custom recover, if you have unlocked the bootloader already then you may be able to flash clockworkmod recovery from within rom manager,
Not sure I have an evo 3d

What do you mean by haven't unlocked bootloader?
I hold the vol. down, power and home button at the same time then vol up to continue it says Odin Mode, product name SPH-D710, Custom Binary download: NO, Current Binary: Samsung official....Downloading do not turn off target!! Been on the screen for a while now.

No u just need Clockwork Mod recovery to flash a rom rom manager won't do it, I had this problem and really rooted again with a method that included clockwork mod in it. I have a Mac so I don't think it'll be the same way but try this. If u can go to the ACS website they are always easier.

First, just to make sure, you wrote Galaxy S 2 in your OP, but you are on the E4GT (Sprint) version correct?
If you are, and used sfhub's Auto Root, did you proceed to option 'C'? If not, you have not yet installed a custom recovery, which is what you need to install custom ROMs.
Try this, hold [Power] + [Vol. Up] at the same time for several seconds (30+.) If you are booted into CWM recovery, you will be all set to flash ROMs, if not you still need a kernel with CWM (option C in the auto root process.) Based on your comments in the OP, you do not have a custom recovery. I believe you described the stock recovery.
Easiest thing to do is go back to the Auto Root batch file and complete option C. This will give you recovery without increasing your custom software counter (counter = bad for warranty.)
Yes I'm with sprint and no I didn't proceed with c thanks for informing me I will try to see if it works. Thanks.

CWM on Rooted E4GT without ODIN/PC? Recovery Exclamation

Alright I used the autoroot method from here - http://forum.xda-developers.com/showthread.php?t=1342728
Now I'm the late adopting noob here but I tried to flash CWM from their rom manager application and after selecting my model it claims it was successful. If you try to boot into recovery it does the normal one. If you try to reboot into recovery from rom manager it gets stuck at the android dude with the exclamation after a short loading bar.
I have watched a couple videos about using ODIN and all. But I was trying to do this without changing anything. If I have to thats cool as it seems there are some stock repacked roms that would be comfortable to someone new like myself.
Phone is currently rooted, EK02. The only thing I ran into was some talk by the Galaxy Nexus rooters saying something about renaming/deleting a file. Most of the things I run into no one ever says how they fixed it just that they did.
Can you just revert back to factory condition (using the same script you used to root and install CWM) and then try again? Or does it produce the same error?

When you say "rom manager" are you talking about the Auto Root package or some other application? I'm thinking some other application because you mentioned "reboot into recovery from rom manager"
All you needed to do to get CWM was, after rooting with Option A, choose Option C and install EK02+CWM.
If you are now asking how to get back to something working, you can ODIN one of the factory restores.

New issues.. Recovery Issues..

Okay, I'm not sure what's going on with my phone this time, but... I was assuming that whatever I used to flash my phone to the EL29, I figured it came with recovery. I thought whenever you Root your phone, you automatically get the recovery app. Well, for some reason, I don't think my phone has recovery on it.
(my battery is full)
I tried to go to recovery.
By doing volume up + power. It goes to the Android System Recovery <3e>
It says "E: update file is backed up: Reportedted
#MANUAL MODE#
--Updating application...
Installing Apks.
Successfully updated application."
So I click on reboot & then it says E: file is written... Update success
Then my phone reboots, and when it comes back on, my battery is completely dead.
Then I keep getting a pop-up that says Attention : no firmware update is available.
I use different apps, that say that my phone has root access, so that's why I assumed I was rooted.
But I don't know what's going on.
is there a different way to get into recovery? Am I doing it wrong? Do I not have the recovery on my phone??
Anyone help me out with any of this, I would really appreciate your input. Thanks

You only have stock recovery, it can only flash official signed files from Samsung/sprint you need to use the autoroot package from sfhub to put either cwm or rogue recovery on, look at the stickies in the dev forum you will find detailed information to help you achieve this

Root and Custom Recovery are 2 separate things. You can have one without the other. If you flash custom recovery in Odin, you'll get the yellow triangle and increase your flash count. There are ways to reset, including USB jig and upgrading to ICS and using Triangle Away. The pre-rooted ODIN OneClick packages give you root, but flash stock recovery so you won't get the yellow triangle nor increase your flash count. Then if you want CWM, you can just use the Auto Root package to install it.
Whenever you boot into stock recovery it tries to install the pre-installed Sprint apps and then when you boot into the first time after going to stock recovery, it searches for firmware. That is just the way they made it work.
I don't know how you initially got EL29.
If you still have root access, the Auto Root sticky can install CWM pretty easily. Just choose Option C and install EL29+CWM-Rogue
If you don't have root access, you can flash the EL29 ODIN OneClick. The link is available in the Auto Root sticky. Choose the NoData version which won't reset any of your Android User Data.

[Q] have root but have no recovery? CWM?

no idea what's going on. i flashed via Odin to get root, and that worked. but i can't get into recovery via power/vol+ and home. also tried vol+ and power but no joy. download works fine.
i installed rom manager to have a peek and that says i "need to have clockworkmod recovery" before i can do anything. the weird thing is in spite of all this, rom manager *can* reboot me into recovery. i just used it to backup my rom just in case.
for now, it seems the only way i can get into CWM is via rom manager? this can't be right since my htc desire and galaxy s2 could do it from a cold boot. had to in case we screwed something up and couldn't boot an OS.
the root guide i used was via here. not2root.com

Here is CWM 6.0.1.5 mate https://hotfile.com/dl/176065007/332cffb/cwm6-recovery-n7100-121014.tar.html, flash with Odin/Mobile Odin. Also read this for root http://forum.xda-developers.com/showthread.php?t=1901196.
cheers
flashed and got into recovery but not at 1st. i always held down the 3 buttons when trying to enter recovery and this time i noticed a flash of "the recovery screen" before it rebooted and went into android.
apparently you just press the buttons and let go with the note 2? not sure if i just realised it now or if this fixed it but either way i got in so tomorrow can flash a new rom.
cheers

[Q] Fixboot.tar Install/backscreen on reboot

I have a Samsung Galaxy S3 SGH-I747 (AT&T) that I updated OTA to 4.1.1 a while back. I just decided to root the phone using Odin3 V3.04 and clockworkmod.tar. I tried using clockworkmod at first but couldn't get the phone to go into CWM recovery mode. It just went into stock recovery instead. Reading further, I was told that I need to flash fixboot.tar first, then clockworkmod.tar, then flash CWM_SuperUser_3.0.7.zip file in recovery mode. When I used odin to flash fixboot.tar and rebooted, it boots the Galaxy S3 logo, at&t chime, then goes black with Amber light. It will not boot fully. I then used Odin to flash clockworkmod.tar, rebooted and it also went to blackscreen.I was then able to go into recovery mode and flash the Superuser zip file and reboot but I'm still getting the black screen. What did the fixboot.tar file do to my phone?? Can I reverse this without flashing a whole new rom? I have search the forum for severalhours now with no luck. Any help would be great.
where did you get your initial information and tar? as well as the fixboot info and tar?
check out this rooting thread here on xda. the purpose is to flash cwm recovery onto your device. you then boot into the custom recovery you just installed and root from there. instructions are on the thread.
recovery mode is: vol up + home + power. release just the power button when your device vibrates

I got it from this link - http://rootgalaxys3iii.com/root-at-t-galaxy-s3/
I am aware of the process you mentioned, but it would not work. It just kept going into standard recovery mode instead of custom recovery so I could never root from there. Thats when I came across this link and thought I needed to flash fixboot.tar first as it states. It did work! I was able to flash clockworkmod.tar and then root the phone, but what good does that do now that my phone is hosed at the blackscreen...There were two sites that said to use this fixboot method. I should have known better...
I just read your thred. Looks like my problem was letting the phone reboot. Is there any way to reverse the fixboot.tar I used? Maybe there is a 4.1.1 boot.tar that can put things back as they were?
via the link i provided, in odin, were you unticking the "auto reboot" box?
i've used that thread method on several S3's with no problems. if you were getting a PASS message then it actually worked.
can you get into recovery now? if so, wipe data/factory reset and wipe cache. reboot.

I used that method from another site and I was getting a pass. It looks like my issue was letting it reboot. When it didn't go into CWM recovery,I used the fixboot.tar and thats when my phone would not boot past the boot screen. I still have some unsaved material and don't want to wipe the phone. I can get into CWM recovery now. Will doing a data/factory reset wipe everything? If so, is that my only option at this point? I don't want to go to factory and lose everything unless I have to.

Well, since I got no response, I did what you said and deleted everything. I still have the same problem. Phone boots to Samsung logo, does jingle and geos to blackscreen with blue light.
Back to my original question. I used the fixboot.tar and it jacked my phone where it only boots to blackscreen with blue light. Is there a fix for this???
