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.

rooting block OTA update?

root the phone will block future OTA update? even factory image installed?
I donwload rom manager from market, it says your 'rom does not support OTA update, please contact your developer', but I have pure factory image from google installed.
is it showing worong thing? or did it mess up my system? or I should never had clicked there?

ROM manager is talking about an ota update for a custom rom, which you aren't running. And if you want to know whether rooting will prevent a future official ota, a search will tell you the answer.

this article says yes. but other places say it might not, but ota update will remove the root.

This.
Twice so far for me.

Rooting the stock ROM will not prevent OTA updates. I've had the Nexus One and now the Galaxy Nexus, and I can tell you that rooting will not prevent OTA updates, as long as you have stock recovery.
What will prevent OTA updates from installing is custom recovery. If you're using ClockwordMod recovery, you will get the OTA update notifications, but the actual update will fail to install. You can still install them manually by flashing the update yourself in recovery. It's easy.
In either case, you'll almost certainly need to re-root afterwards.

stock recovery? you mean stock image from google.
logically it make sense custom roms don't get update because they are modified from orginal copy, updates are for original condtion copy so may not fit into them correcty. but what exactly is preventing the update there?

I dont have custom rom or recovery and my ota failed.

after root?

OTA updates install via recovery, so they fail with custom recovery (ClockworkMod). They should install with stock recovery. This is assuming the stock ROM (even rooted), not a custom ROM since as you said that definitely won't work at all, since the update is meant for the stock ROM.
If an OTA update fails on the stock ROM (even rooted) with stock recovery, something else is usually wrong. It's definitely possible, but not the normal situation. In two years with my Nexus One and now Galaxy Nexus, I've never had an OTA update fail on a rooted stock ROM (both automatically with stock recovery and re-rooting afterwards, or manually applying the update with custom recovery).
I know with the Nexus One, some OTA updates failed if people had rooted and removed some of the built-in apps or otherwise messed around with /system. If things like that get modified, there's a good chance the update will fail.
Just my experience... hopefully someone else can give some further input.

Getting root access only involves two files being placed in the /system partition:
1) the su binary is placed in the /system/bin directory; and,
2) the Superuser.apk file is placed in the /system/app directory.
Other than that, there are no other changes.
As phazerorg said, rooting will not affect getting the OTA.
There are two separate issues here:
1) Receiving the OTA update; and,
2) Having the OTA update install.
Everyone on a stock ROM (and even some custom ROMs) will receive the OTA update (eventually).
As for installing the OTA update, there are again two issues here:
1) Having the OTA update install automatically; or,
2) Installing the OTA update manually.
To have the OTA update install automatically, you need the following:
1) A stock recovery;
2) A stock ROM (and it CANNOT be de-odexed);
3) All the original applications need to be present (like Goggles, Google+, etc.)
4) Root or no root makes no difference; and
5) A stock boot image.
If you have a custom recovery flashed, then you can manually apply the update through the recovery. However, all the other items from the list above still apply.
If you flashed a stock de-odexed ROM, or a boot image (i.e., kernel) that was modified somehow, you need to flash back to the stock version of each or else you cannot apply the update.
Hope this clears up some things.

Thank you for taking the time to clear this up.
I unlocked the bootloader, rooted, and then installed CWM to make a back-up. I am still, and plan on always, running the stock Rom (4.0.2 right now). I was worried about the OTA's but based on what you said, I can still download the update, but I would need to use CWM to actually install the update? Or would I just need to flash the new update via an updated-stock-rom?

Your phone has several different firmwares on it. Radio, bootloader, recovery and the actual OS. Recovery is what lets you "recover" the OS when things are screwed, and also perform other maintenance operations... such as installing OS updates. You can boot your phone into the bootloader or recovery, in addition to the OS.
Custom recoveries such as ClockworkMod let you do even more things, such as flashing updates or custom ROMs of your choice, or taking nandroid backups (which are basically "images" of your current ROM. Restoring a nandroid backup brings your phone back to exactly how it was at the time the backup was taken... very useful when trying new ROMs or messing around! This is reason enough to use a custom recovery in my opinion).
The stock OS only knows how to install OTA updates using the stock recovery. Stock recovery is what comes on your phone (or from Google via an update). Custom recoveries like ClockworkMod are generally based on the stock recovery, but are different and the OTA updates don't work with them automatically. You can definitely install OTA updates using custom recovery, but you have to do it manually. After you get an update notification from the stock ROM, the update zip file should be downloaded and located in /cache and you can use ClockworkMod to flash it. I also keep the Superuser zip on my phone at all times, so I can flash it immediately after flashing an OTA update, which lets me retain root.
To answer your actual question, I would say that stock recovery is one part of the stock image. But most people probably think of the "stock image" as being the OS side of things. You could have the stock image OS, but still use custom recovery. I hope that makes sense.

where is the recovery/stock recovery and how to access?
when I boot into fastboot, there is up/down arrow, when I click on revoery, i see an android robot with x mark on it.
I used cwm did a full system wipe, the phone went dead, stuck on bootloader screen, then I flashed stock image from beginning.

In CWM go to Recovery (Hit the "power" button to select), then go to "Back Up and Restore" (use the "power" button to select), then go to "Back Up". Make sure you have at least 50% battery when you do this.
After it finishes copy the contents it should be in /sdcard/clockworkmod/backup I back it up to Dropbox, so I can have the files where ever. (PM me if you'd like an invite so we can both get more space on Dropbox. If you do use Dropbox, I'd encrypt the data with something like TrueCrpyt.)

With the phone completely off, holding down both volume up and volume down and then holding the power button will get you into the bootloader. From there you can use volume up/down to scroll through options to boot into recovery. Alternatively, if you're already rooted, you can use apps like Quickboot to just reboot directly into recovery.
I never actually tried the stock recovery on my phone... I unlocked the bootloader and flashed ClockworkMod and rooted as soon as I got the phone home from the store. Normally, selecting "Recovery" from the bootloader menu would get you into recovery. The only time when I saw the android with the X was after trying to apply the first OTA update (just for fun even though I knew it wouldn't work without stock recovery).
If you have ClockworkMod (CWM)... the backup/restore is nandroid. It's called nandroid because it's NAND flash, and the OS is Android... NAND... Android... Nandroid.
But... make sure you backup /sdcard to another place, because if you do a full factory wipe, you'll also lose all that since they're stored on the "sd card", which is really the data partition. Doing wipes in CWM doesn't wipe /sdcard, but factory resets do. I reguarly rsync my /sdcard to another computer over wifi so I'm sure to always have a completely external backup. That's never a bad idea when you're messing around with this stuff. Too many backups never hurt anyone. Too few backups, on the other hand...

Yes, if you have CWM installed, you can use that to install the update. No need to flash an updated stock ROM.

I just tried to access my stock recovery. But I see the Android robot with a triangle with ! inside. Then I can't do anything with it - power button and volume keys have no effect. What does this mean? I'm running stock rom with stock recovery but with bootloader unlocked.

[Q] Question - Recovery Mode without WCM

I just re-lock the bootloader and i removed the root using nextoolkit.
and before that, i didnt put CWM in my nexus.
anyway, i was looking at fastboot mode, and tried to enter de recovery mode without CWM... when i did so, it just apeared a kind of "android error" with a exclamtion mark. the buttons were freezed and i couldnt do anything. so i waited 5 minutes and it did a automatically reboot
-why my recovery mode showed this "android error"?
-what purpose of a recovery mode without CWM?
-recovery mode only works on root devices?
-did i do anything that can cause me problems by entering the recovery mode and waiting those 5 minutes?
Thank you

The Android with the exclamation mark is the stock recovery.
Stock recovery is useful, but not quite as useful as CWM or TWRP because it doesn't let you flash ROMs or mods, etc.. Stock still lets you do a factory data reset and a few other things.
Recovery works on stock devices (necessarily), but you need to be unlocked to flash a custom recovery and use those advanced features that the custom recoveries offer.

i have a galaxy NEXUS, but the image i found was nexus S (but the problem is the same)
i found this in another forum, and every body sad it works:
"1. flash that through fastboot, that is the cwm for lte
2. reboot phone,then find the file named /system/recovery-from-boot.p and either rename it to '1recovery-from-boot.p' without the quotes or delete it, (i renamed it)
3. reboot into fastboot mode and then chose recovery, you can then make backups or whatever with out the dead android guy with the red triangle containing the exclamation
i didnt make this up just followed the directions in the above mentioned thread good luck !!!!"
I found the "recovery-from-boot.p" but i couldnt delete it because is in system folder? only with root acces its possible to delete it?

Beamed from my Grouper.

[Q] Cannot boot to recovery (on two completely separate phones).

I flashed CM10 onto my phone a couple weeks ago, everything went smoothly. Today, I reverted back to stock and locked the bootloader so that I could receive the stock JellyBean update. Well I download the update, reboot phone into fastboot, attempt to go into recovery and I get the red triangle !. I know this is an issue with the phone apparently not finding a recovery boot but why didn't my reverting to stock reinstall the stock recovery? Does anyone have any guides they suggest to get stock recovery back? (I've found a few but thought I would ask).
Now, this is understandable that my phone can't boot into recovery since I flashed CM recovery onto it and whatnot, but I attempted to boot into recovery on my girlfriends phone (same phone, NEVER BEEN UNLOCKED OR FLASHED) and it can't boot into recovery either... Is something going on here or am I just missing a huge piece of the puzzle? I don't really want to have to flash anything on my girlfriends phone to fix it, she's not into the tinkering and would rather not have her data reset. Any help would be appreciated.
And for the record, I did a search to figure this out but at the very least I can only find solutions for people who have flashed CM or similar and nothing pertaining to the problem my girlfriend's phone has.

Unzip the factory image you get from developers.google.com/android/nexus/images
Then use fastboot to flash the recovery.
EDIT: red triangle doesn't necessarily mean the recovery is broken. It's just the way it is. If you wish to flash a 3rd party ROM you'll need to flash a 3rd party recovery.

I think you are confusing a few things here. First off, the Android with the red triangle IS the stock recovery main screen. (If you want to flash the update manually, you need CWM -- go into fastboot mode and type: fastboot flash name-of-recovery.img, where name-of-recovery is the recovery that you downloaded and want to flash.) Second, you need the stock recovery for an update to install over-the-air, but you need a custom recovery if you want to flash it manually.

So in the context of my girlfriend's phone where nothing has been done to it in the 4 months she's had it, why would it be giving the recovery error? Also, does flashing the recovery wipe the phone?
It's funny too because I just got the JB OTA but I'd still like to get this figured out.

Back to stock rom??

Hello all, I was wondering if anyone can point me in the right direction. I have a acer iconia a100 rooted and currently running the carbon rom (4.2.2) and twrp recovery (2.6.3.0). I would like to go back to stock rom (ICS). I have not changed any kernals or anything like that. Can I just restore my nandroid backup of my stock rom or is there something specific I have to do? Also, I just looked and I dont have a stock backup with twrp, only with cwm. When I unlocked bootloader, I installed cwm, then must have done a backup of stock rom, then flashed carbon rom, then switched to twrp and made another backup so I would have to go back to cwm to restore nandroid. How do I go back to cwm from twrp?? Thanks for the feedback.
I looked in my internal storage and it looks like I have 2 zips, fastbootrecovery.zip and xsposeddisabler-cwm.zip, do I flash one of these?? and if I do, can I do it with es explorer?? Thanks

Just the stock ROM or completely back to stock, 100%?
If you don't know what those zips are, or how to use them, then don't use them, period.
To get back cwm you can use fastboot to flash it back on or use one of the cwm installers in development, if any are still there, if you want to do it with fastboot you'll need some stuff to get ready, most of it should be there from when you rooted the first time, then a couple lines in a command prompt and you'll have it back. There's also stock rooted ICS ROMs available, so depending on what you want we can go from there.

I am going to sell my tablet so I would like to go to my backup of my stock rom. When I restore my stock backup, I can just do a full wipe, that will get me back to the starting point of just the basic rom, right?? That will wipe all my data from the backup rom, or will a full wipe erase the rom too?? I want to get back to the basic rom (just like if I install a new rom) have to set up accounts, wifi, etc).

http://forum.xda-developers.com/show....php?t=1510706
Root Instructions here:
http://forum.xda-developers.com/show....php?t=1531646
Unlock your bootloader for fastboot, follow here:
http://forum.xda-developers.com/show....php?t=1557445
once you have done all of the above, you should be ready to flash this recovery. Make sure you have ADB up and working properly. And place the recovery.img in your working folder (see below)
1- Open a command prompt in your working folder (usually in your platform tools, mine is C:\android-sdk-windows\platform-tools) make sure you are administrator.
2- Connect Tablet to pc and get excited.
3- Type: adb devices (verify your Tab is connected and listed)
4- Type: adb reboot bootloader
5- Once bootloader is in fastboot type: fastboot flash recovery recovery.img
You will see writing recovery, flashing recovery, etc.
6- Once flashed Type: fastboot reboot
7- Profit
But it says make sure you have the latest ics leak?? Are they refferring to the rom?? If so, I currently have carbon rom istalled which is jellybean. This will not work then?? I am a little confused and any feedback would be greatly appreciated.

Does anyone have any suggestions?? Thanks

Well, before the tab got official ICS, we had a leak. If you had read down the topics some you would've found it. You do not want cwm, you want twrp.

To just go back to stock to sell it you'll run into a couple issues coming from 4.2+, namely the storage path changes, you'll retain the /0 folders, however many were made. Otherwise following the guide that roman made will work to go back to 100% stock, I'll see if I can get a link, I'm in a waiting room with crappy data lol
Edit:
That guide will work for installing cwm, basically get your cwm image then get fastboot going, fastboot flash recovery cwmimageyougot.IMG

Best way to return to 100% stock. No need to fuss with recoveries just install what he says then the ROM does the rest. While in twrp remember to go delete /0 directories or they'll remain there forever. Or until its deleted at a later date, but if you have stuff in there you should do it prior to going fully stock again.

Thanks for the response, youve fully confused me with the /0 folders?? What exactly is that?? When I go to es file explorer, I see sdcard0 (which looks like the internal storage) and sd01 which looks like my ext sd card. Is it one of those your are talking about??
Also, you said something about go delete in twrp, I went into twrp and did not find anything with that name?? am I deleteing something in twrp. Could you spell it out for me since I am a noob when it comes to reverting a device to stock. Thanks for taking the time to explain this.

that is something happening with cwm. i had this problem. it keeps creating a folder names 0 and keep moving old files into that whenever you install a new rom.

Hello guys. I need your feedback. I have a A100 that is rooted and is currently running carbon rom 4.2. I am going to be selling this in the next couple weeks because I just don't use it anymore now that I have a second pc.Do you think it would be more advantagious to sell this just the way it is (rooted and custom rom) or should I take it back to completely stock? Or if it is more advantagious to sell it with a custom rom, which rom would you guys suggest?? Thanks again for any and all suggestions.

Please Help!! I was trying to go to stock ics and these are the steps I used.The simple method to revert back to stock ICS from a custom ROM on an A100.
+++Locked bootloader, no custom recovery, no root. Full stock .014 rom. It will recieve OTA updates to latest Acer version.+++
Get Ready
1) Download this flashable Stock recovery zip, and place in your normal flashing location, - Thx 4 help pio
http://db.tt/VLmnMCzq
Also uploaded below
2) Download the Official .014 Stock ICS rom
The stock ICS zip from zeronull. http://forum.xda-developers.com/show....php?t=1611696
Here is a second link to it. http://ubuntuone.com/7DZtbNqZzOk7qsaQxNk99a - thx zleto
3) Rename the Stock ICS rom to "update.zip", no quotes (make sure you have "hide known file extensions" UNCHECKED, in the folder options). And place it on the root of your microSD card. This will allow you to see the file extension to verify that it is named properly.
Get it Done
1) Flash the Stock recovery zip with your custom recovery. Then wipe cache, davlik cache, and wipe data/factory reset.
2) Reboot to system.
3) Allow it to sit for 5 minutes or so.
4) Then Power off.
5) Update from the microSD card by holding down the power and volume rocker closest to the corner at the same time, until you see "erasing cache .".. ect, ect. The stock rom install should start by itself, dont touch anything, wait for it to reboot.
****** If it won't boot do a factory reset (with the hardware buttons, see below) and/or try to reflash the ics rom one more time. ******
Quote:
To perform a Factory Data Reset use the following steps:
1.Place the rotation lock switch in the up position (tablet held in portrait). Or to the left if held in landscape.
2.Press and hold the Volume down button, which is located farthest from the corner (it is volume up, if held in landscape).
3.With the Volume down button held, press and hold the Power button for 3 seconds then release it. Continue holding the Volume down button.
4.Once the tablet vibrates, switch the rotation lock on and off repeatedly while still holding the Volume down button.
5.Release the Volume down button and stop switching the rotation lock once the "Erasing Userdata..." message appears in the upper left corner of the screen
Now I get the android symbol with the red triangle, that stays for about a minute, then it reboots and stays on thye acer screen. When I did the steps and was going to reboot, I received a waring while in recovery sayiny that I dont have a op installed. I did it anyway, as posted and now I'm stuck, can anyone PLEASE help me.I tried doing a reset with steps 2 though 4 but while pressing the vol up and letting go of the power button, it does not vibrate.
I try to boot into recovery with vol up + power, it boots than says erasing cache, then booting into recovery, the the android synbol comes up with the red triangle.

I can't even get into recovery. It says bootloader (unlock mode) when I pwer it on. If I press power + vol up, it says erasing cache, then booting into recovery kernal, then the android symbol comes up with the red triangle.Thanks for responding and since this is the wrong thread, can we discuss this in the other thread?? While I was typing this, the android symbol with the triangle was on the screen for about 2 minutes, then it just rebooted and now its saying acer acer acer acer acer on the bottom of the screen.

Can anyone help me out with this please?
