Nexus S won't go into recovery?

I am trying to unroot my nexus s. I can't get back into recovery mode at all. I get the android guy and a ! screen. trying over and over still gets me back to this screen...... what to do?

Vol UP and POWER will take you to the bootloader.
fastboot boot clockworkrecovery.img
you should now be in clockwork recovery. It will revert back to stock on reboot, so you will need to mount system and rename the install-recovery.sh to install-recovery.old
I believe it is in the system/etc/
adb reboot bootloader
fastboot flash recovery clockworkrecovery.img (this will replace the stock recovery)

I dont have clockwork recovery on my device..... I kind of need a dumbed down walk though. I tried the unlokr's walkthrough and thats when I found my device won't go into recovery mode. It tries and then goes to the above mentioned screen.

http://forum.xda-developers.com/showthread.php?t=1000722 read through this long thread that I took a user to install Clockwork Recovery (or just look at the stickied thread in General in regards about rooting.. it includes flashing Clockwork)
this 7 page thread is dumbed down to the point where it cannot be dumbed down any more.

If its still stock after you select recovery it will show you the image and then you have to hold even power and volume up again or just volume up I can't remember.

If you can see that android with exclamation mark, i think you are already unrooted.

You are unrooted and completely stock it sounds. If you want Clockwork installed you will have to unlock the bootloader, fastboot OEM unlock, then root or leave it unrooted

yeah, but what if the user cant find the "install-recovery.sh" file? for instance my "etc" folder doesnt have that file and i'm rooted.

then the stock recovery won't keep reinstalling itself and CWR will be default.

When I turn the device on I still have an unlocked bootloader. im trying to re-lock it, and nothing is working

I had trouble going to the recovery menu when trying to manually update to 2.3.3: when you see the android robot with the exclamation sign after selecting recovery, you're supposed to press vol up + power again to access the file selection menu. However, pressing the combination would do nothing for me unless I pressed it like 10 times. Then I would glimpse the recovery menu and the phone rebooted unexpectedly.
After an hour or so of random unwanted reboot cycles, I pulled the battery out, put it back in, tried again the exact same way I had just been trying and it eventually worked.
Don't know if it has anything to do with your issue but maybe it helps?

Actually I figured out how to get into recovery with the exclamation mark and andriod moniker on screen.
Use the vol up and power key and simply press them at the same time and release both immediately.

Am I bricked?

I'm not sure if this is a "brick". I'm abel to get into recovery but anytime I try to boot, it just stays in the 4GLTE flash screen forever. I had successfully rooted it and loaded CM10, but then it failed the last nightly I loaded and told me I had unauthorized software, and now this...
I just tried going back to stock, but it doesn't help. The flash seems to work, but I get the same problem.
I'm seriously sad right now

Click link in sig...start with section 2 going back to stock , then root, then UNLOCK BOOTLOADER! Now you can flash cm10.

When I reboot into recovery (which is actually becoming tricky now - as I need to quickly hit up-volume before it normal boots), I don't see any options for wipe/factory reset. I do see the green 2D android though... but there are no options. I'm just in ODIN mode.

"ODIN mode" is download mode (with the 2D android background), not "recovery mode" (with a different, 3D android). In step 3, you held home+vol down+power to enter download mode, then pressed vol up to confirm. In step 8, you're going into recovery by holding home+vol up+power.
You don't have to be fast; just press the power button last and hold it until you get into recovery or download.

The reason you got the "unauthorized software" error was that you didn't unlock your bootloader. You should do more reading to prevent soft bricks like this in the future. Next time, root your phone, unlock the bootloader, flash a custom recovery, reboot into recovery, and make a backup(!) before trying to install a ROM. :good:

When I try that, it starts to go into recovery mode (and I see the 3D android), but then it boots up normally and hangs at the 4G LTE screen.
The background to this issue is that I used the Guide you linked to root (prior to bootloader being avail), and had CM10 installed. Everything was great and functional until I tried installing This issue has materialized after installed the privacy app (forget the name) which needed root and started cycle rebooting the phone. So I went to flash the latest CM10 nightly, only to hit this issue.
I never flashed the kernel - figured rooting through the initial work around the community had, would have been sufficient in perpetuity... oops

UPDATE: I was able to get into recovery (the combo button timing is definitely more sensitive than before. ...and now it's booted up normally. THANK YOU!

Help, unable to get back to recovery.

So I'm selling my TF700 and decided to reset everything. I made the mistake of wiping the data. When I rebooted from TWRP I now get stuck at the boot screen (white asus logo that says unlocked). It will not let me boot into recovery, the options aren't there. Any idea on how I can get back to recovery?

You can try to hold the power button + volume down button for ten second. Can you access to your bootloader?

[Q] OnePlus One unique softbrick?

I rebooted my OnePlus One yesterday and found myself in a weird situation. The phone would go to the initial OnePlus logo then after, a smal android logo with a red warning sign appears for a split second, and I boot into the CM stock recovery. I can't turn it on or enter fastboot, nor can I turn on ADB Debugging on my phone and would really appreciate help as I do not want this phone to be gone. Pretty scared guys, help would be much appreciated!

I've never seen this problem before.
I supose you are bootloader unlocked, rooted and have costum recovery, right?
For fastboot, if it does not work normally, try: up button + power with the phone connected to the PC; if it does not work, try the same button combo + plug the phone to the pc while you are holding down the buttons.

Thanks for the prompt response. I think you should also know that I attempted to put a custom recovery on my OPO, but after saying that it worked, I only loaded into the CM Stock Recovery. I do not, have my phone with me at the moment as I did not think it would be necessary to bring to school with me, but I will attempt everything you have said. Thanks for the help so far!

I attempted both ways but nothing happens as I press the buttons. It will only boot in the CM Simple Recovery.

I believe you messed it up for good, since you: can't get into fastboot; have no recovery; have no backups... If you could get fastboot to go you would only need to flash twrp and then sideload a rom =/
Does the stock recovery let you sideload?

Yes. It does.
Download the stock image. I'm sure it will be there somewhere in the forums.
Then go to recovery and do the following:
Select 'apply update'. Then you either have the option to apply update from Internal Storage or from adb.
Select adb and enter: adb sideload update_filename.zip

assuming it's the stock android recovery, i'm pretty sure it allows for sideloading.
Def sounds like something got flashed to the wrong parition though

[Q] Can't boot into recovery?

So, I got my new OnePlus One today and I tried to get CM12 onto it. I was following the [GUIDE] How to Install CM12 on the OnePlus One- Android Lollipop/5.0 on the OPO forums, and everything went well until I tried to get the TWRP on there. I flashed the recovery and rebooted the phone. I turned it off and then tried to boot it into recovery but it doesn't, it just hangs at the OPO logo until I hard-restart it.
I've tried factory resetting it and doing
fastboot oem unlock
but nothing happened. The factory reset pretty much just reset the phone. I think I might've messed up the kernel. How do I fix it?
EDIT 1: I've tried reflashing twrp recoveries and nothing. When I hold power+volume down, it powers on, shows the one plus logo, then reboots and just goes to the lockscreen.
UPDATE 1: I managed to manually flash all the CM12 files and use lollipop. I haven't tried the recovery yet but I'll keep you guys updated (if any of you even care).
UPDATE 2: Apparently flashing CM12 made the recovery work. Everything works as it should and the OTA to the most recent CM12 worked perfectly.

You're probably doing the button combo wrong. Hold volume down, then hold power (so you're holding them together), when you see the boot logo let go of power but keep holding volume down until you reach recovery.

I was curios and enabled advanced reboot to try and boot into recovery and it worked (after I had flashed CM12). Everything's working now.

How did you manually flash CM12? I think I'm having the same trouble you were having. I used the oneplus toolbox from the forum to unlock the bootloader, then flash the TWRP, but no luck in getting into recovery mode. It just boot loops with the oneplus logo until I release the volume down button at which point it then boots to the lock screen.

@Heisenberg I'm also having trouble getting into recovery. I've tried the different button combos (power + vol down; power + vol down and release power) as well as the advance reboot options to get into recovery, but they all fail. I get the 1+ logo and after I let go of the volume down button the screen goes black and boots again to the 1+ screen and then to the lockscreen. It's almost like it doesn't recognize the recovery. I tried putting the stock recovery back on using the image in the OnePlus One toolkit folder, but that one doesn't work either. In addition to unchecking the "CM Recovery Update", are there any other settings that could be causing problems?
For background info, I initially used the toolkit interface to unlock the bootloader and then flash the recovery. The bootloader unlocked with no issue...it wiped my device and I was in sync with the "How to root" video posted by alex.inthi. I got sidetracked after the (seemingly) successful flash of TWRP onto the phone I kept getting booted into the Cyanogen recovery. I realized out that I needed to uncheck the setting to keep it from overwriting TWRP and after that was not able to boot into recovery. After finding your beginners guide (thanks, by the way, very well written) I tried using fastboot from the command line as you show, but still no luck.
Thanks in advance for any help...

Okay, I must have been having a special kind of moment - I've got TWRP 2.8.7.0 running on my handset now. I may have been holding the volume down button too long, or it may be that I was using an older version of TWRP, but I'm going to go with the former. I've also been able to successfully flash and boot into Philz 6.59.2

Having the same problem
I am having the exact same problem and cannot seem to find a solution. Recovery screen just doesn't appear, but goes to lockscreen.
Tried erasing, flashing both twrp, philz etc., but nothing works. The phone doesn't recognize the recovery status. Advanced booting does the same.
Update CM-recovery is checked off, phone is unlocked. I've followed every step of the big guide down to every detail.
Is manually flashing the 12.1 ROM the only way and in that case: is it hard for a relative newcomer?
