Recovery issues

When I load the bootloader with power and volume up and select recover it gives me the triangle picture with an exclamation mark in the middle. I am unlocked and rooted. I installed clockwork and can get to it from rom manager but not through recovery option. Help please!

i think this is covered in the FAQ, and it's definitely discussed in several threads already.
The triangle is the stock recovery. If you've updated to 2.3.1, the stock recovery is restored by a startup script every time you boot the phone. You can disable this by renaming the file /etc/install-recovery.sh. Then install clockwork again.
If you want to stay on stock recovery, to get into recovery, you do the vol up and power button, then from fastboot select recovery. Watch the screen closely when the phone reboots...for a second or two you'll see a box pouring an arrow onto an android. During that screen push power first (hold it) then push volume up. Timing is important.

[Q] Help! urgent! stuck on exclamation mark and android

Think I rooted it , tried to go into recovery, now I'm stuck. anyone here? right now? maybe can give me live assistance, over IM of some sort? pleaseeeeeeeeee

Looks like you're in the stock recovery, and the clockwork recovery mod was overwritten (it does that every time you reboot).
you can refer to this post for instructions on flashing the cw recovery again and rooting: http://forum.xda-developers.com/showthread.php?t=931865
it's basically just a fastboot command.

What do you mean you think you rooted it

Also someone posted Odin with stock image...perfect for situations like this

i don't think we need to go the Odin way just yet
it sounds like he's in the stock recovery, he just need to do the fastboot, and all that stuff to get things going

The box pouring an arrow onto an android and/or the exclamation mark android is stock recovery. From there, just hit power first, hold it, then hit up arrow, you should get into stock recovery.
If that didn't work, pull the battery and let the phone boot normally. IF you're on 2.3.2 or higher, the install-recovery.sh script will replace the stock recovery in case you some how munged it up.
Reboot into fastboot with the volume key and power key, then when the box with the arrow appears do the power key hold and press the volume up, you should be in stock.
As others said, you can also just fastboot boot or fastboot flash the clockwork recovery image.
You're phone's not bricked, so no panic necessary.
edit: oh, and finally, if you actually succeeded in rooting, you could also just use ROM Mgr app to flash/boot to clockwork recovery, which is what you really should be using.

[Q] Vol. down + power dosen't enter the bootloader

After I updated my (unrooeted/locked) Nexus S (9023) to 4.0.3 I wanted to try the 4.0.4 upgrade. After the 4.0.3 the recovery mode lost the backlight, so I figured the it was a good time to root.
I tried this one-click script to unlock. It worked and I installed CWMR and flashed the 4.0.4 upgrade. After a reboot the phone had ICS 4.0.4 and got root.
But not all is working. I lost the ability to get into the bootloader by pressing 'vol down.' & 'power'. The phone just starts normally.
The only way I can get into the bootloader, is to "reboot to bootloader" from a command line. If I choose recovery, I get a picture of an android at its back with a red ! (2105.dk/temp/img_1161.jpg). After two minutes it automatically reboots. What has gone wrong? What does it mean? And how can I fix it?
I'm new at this, so i'm out of ideas

try Vol up + power

Ahhh... now i'm feeling a bit stupid
Okay, i'm able to get into the bootloader, but the problem with the recovery still remains. (what does the picture mean? - 2105.dk/temp/img_1161.jpg)
I've tried both CWRM and TWRP. They seems to flash with no errors, but i still can not get them started from the bootloader (fastboot mode?).

Not sure if it's what you are looking for since I can't see the picture you are talking about but I think it's the recovery "security" screen. When you are there press power first and maintain it to press vol up, you should now be into the recovery...
Also remember stock rom has a script that overwrites any custom recovery with stock recovery each time the rom loads.

Yes, pressing [power] + [vol. up] at the recovery "security/error" screen, starts up a recovery.
I also didn't knew that the stock ROM overwrites the recovery. I never seen it mentioned any where else.
Thanks for the hints.

Okay, after learning how the stock OS trying to reinstall stock recovery, I managed to rename /etc/install-recovery.sh to *.bak
Now the stock recovery stays away, and CWM recovery stays on permanent.
Also, the error screen doesn't show up any more. (never found out what it means)

[Q] Root + CWM without unlocking bootloader?

Hello, is there any possible way how to root Nexus S GSM ICS 4.0.4 without unlocking my bootloader.
I made it once when I wanted to update from 4.0.3 to 4.0.4 by using UnlockRoot and then instaling CWM via RomManager, but after update my recovery/CWM doesn't work, I am just getting a "dead" android with red triangle above him. It a bit wierd because I still have superuser app,but RomManager is not able to install CWM.

For as far as I know it's not possible.
I updated my NS to 4.0.4 from 4.0.3 by unlocking the Bootloader and flash CWM on it, from CWM I flashed the update to 4.0.4 and it works like a charm.
The "dead" android you see is for as I know another bug of 4.0.3, the recovery mode simply does not work.
If you are going to unlock the bootloader, please create a backup of everything, also your internal memory (photo's, videos, music etc.) Since the whole phone will be whiped.

Ok, i might be wrong but does lock on booting screen mean that my bootloader is locked? Someone told me that it says that my bootloader is unlocked...I lil'bit confused and lost
And maybe last question: Is it possible to flash CWM via Odin like other samsung devices?

Lock on the Google screen means it is unlocked. And AFAIK you can root and flash ROMs without unlocking.

ok, thanks for providing info.
Now i have to solve my not working recovery, is there any stock CWM kernel?

If you see the dead android with the red triangle above it, just hold the power button and press the vol.+ button and you'll see your recovery

Note that the padlock is actually open, hence "unlocked". Locked bootloaders show no padlock at all.
I believe there is -currently- no "official" way to root 4.0.4 without unlocking the bootloader, so i wouldn't count on it considering we have a relockable bootloader (and hence don't need exploits).

Still having prob with recovery, i flashed it via adb fastboot, but after restart is my CWM lost (really not there) again

Rename /system/etc/install-recovery.sh to something else.

problem with recovery
I also see a dead android but in my case backlight also dies out and when I press vol up + power button, phone just reboots

The official 4.0.3 has the recovery broken.
As the recovery mode cannot be used, I think unlocking bootloader then flash CWM recovery become a must.

Ok, i will try but right now i have to fix my superuser app, it's gone mad, it is not asking about permission, some apps gets it, but my root explorer not...i tried to reinstall root expl. but it didn't help, tried to delete SU data and nothing, still not getting permission for r.exp.

There is an exploit that you could use you to get root without unlocking BL or wiping phone. I used it myself and it was super easy. Unfortunately, the exploit was closed in 4.0.4(so I've heard).

if your bootloader is unlocked it should say : “LOCK STATE – UNLOCKED”.
If you have a dead android and exclamation mark, it is the stock recovery. Press volume down + power button + volume up, in order. This will give you the stock recovery.
For some reason the new ICS update still has the 2.3.6 security.

About this thread topic, is there any way to root without unlocking?
When I was in 2.3.6 I had my phone rooted without unlock, but lost root after the ICS update althought I still have the Superuser app in my apps even after a factory reset, so I assume it was installed as a system app.
Can I do anything to regain root now that I have Superuser already installed?

Lock on boot screen = unlocked
I think you can flash cwm via odin or you can try flash the cwm 5.0.1.0 via rom manager, it works for me...
Here's CWM 5.0.2.8

First press volume down + power + volume up. This gets you into STOCK recovery.
Since ICS has a problem with the CWM recovery loading up. You can force it to go into recovery.
Heres how
type this in cmd prompt (Make sure your command prompt search is in the correct folder. Press shift and right click on your folder you have your img in. Than click run command prompt in the list): fastboot flash recovery <RECOVERY IMG>
download my IMG uploated below for the latest recovery

[Q] Can't get to recovery after (successful) upgrade to KK.

Hi,
just got time to update my 2nd XT925 to KK (RSD'd back from CM11 JBBL to stock SFR rom, let the phone find its update and apply it, everything went fine).
But whatever KK recovery I try to flash, it gives me an exclamation mark and nothing else (I'm unlocked, yes).
Don't know what's happening here. Can someone helps please ?

Are you saying you are trying to flash a recovery or are you trying to GET to the stock recovery? If you are trying to get to the stock recovery, the key presses to get to it have changed.
Your best bet is to power off your phone. Then, press and hold power+vol up for a few seconds until you see the menu come up. Then, press vol down to highlight Recovery and then press the vol up button.
Eventually, you'll see the "Dead Andy". From there, press and hold vol down+vol up+power. You might have to do it a couple of times. Eventually, you'll be in the recovery but for the XT926, it's kind of hard to read because for some reason, they decided to make it dim.

No (but thanks anyway). What I tried to was only to install a KK recovery for CM11.
I successed but I had 2 problems mixed: the 1st one was that the Linux version of fastboot (or mfastboot) did'nt work with the new bootloader. Both were complaining about "(bootloader) Variable not supported! ". Had to find some old laptop with Windows installed to use it to flash the recovery without error.
But even then if I just let the phone reboot, I would'nt get the new recovery (just the stock one after the keypress you speak about). I had to go straight from bootloader screen to the recovery (by manually rebooting) to get it work. Looks like the standard boot just restored the stock recovery each time I tried.
Thanks anyway, it's working now.

Variable not supported comes up under some Windows, but it usually still works.
You never go straight to the bootloader when you reboot. You have to reboot the phone (or turn it off first) and then press and hold vol up+power. Then, from there, you use vol down to select recovery and then press vol up.
It never boots directly into the recovery unless you tell it to via an ADB command or from within a custom ROM that allows it.

Keep in mind, the stock recovery will override the custom recovery if you don't immediately boot back into recovery. Flash recovery, when that's done, press power to shutdown, and use the method Bolski described to boot into recovery.

Let me see if i undestood.
You say that if you don't boot right into recovery, the stock one will overwrite CWM/TWRP. So i understand that, after very reboot you must reflash recovery if you want to use it again.
Or am I missing something?

It won't reflash every time. You only need to boot straight into recovery the first time, so that the update binary completes. After the first time, you'll be good.

I think this may be the problem I am having. I cant get my 926 to boot to recovery from fastboot after I load CWM recovery. Is there some trick?
