if you mean not only unroot but also reflash a stock rom, you will have to boot to bootloader(by press vol+ and power to turn on your phone) , then flash clockwork recovery
-place the recovery3101.img in the tools folder and type the following command
fastboot flash recovery recovery3101.img
Click to expand...
Click to collapse
then select recovery
and at last flash a stock rom just like you flash superuser.zip

You are running stock recovery (Most likely due to stock rom loading the stock recovery on your phone every time it reboots.So just connect your phone to PC and flash cwm recovery then you can unroot your phone easily.

Dead recovery console?

So I was rooted with Clockword recovery. I just updated rom manager to 3.0.0.0 and flashed the new recovery image with it. Through the UI, I tried to do a backup but when the phone restarted, it was stuck at the fastboot screen. I tried to manually go into Recovery, but the screen goes black -> google -> fastboot. Tried to turn it off and hold volume ^ + power = fastboot but still can't get into recovery.
Advice?

As long as you can still get into fastboot you should be recoverable. Head over the development section and grab a copy of the CWM 2 recovery image and try re-flashing it. That should at least put you back to where you can get into Recovery.
You could also try the stock recovery image in one of the threads there, but I've seen reports that it doesn't boot either.
Here's the thread for it: http://forum.xda-developers.com/showthread.php?t=875875

Not able to boot into custom recovery

Using the LG Google Nexus 4 ToolKit, I did the 1 click for all operation [unlock, root,rename,busybox, custom recovery twrp]. I'm rooted properly but I'm just not able to boot into recovery. I tried booting to fastboot, selection recovery with the volume rocker, then pressing the power key, but this just got me back to Android in a minute or so. I downloaded an app from the Play store which boots into recovery but it also boots me straight to android.
I tried separately flashing the recovery via the ToolKit but again I always boot straight to android. How do I fix this?

flash your recovery via fastboot. fastboot flash it, dont fastboot boot it. fastboot booting it only gives you a one time use. also, if you are using the stock rom, you have to delete the recovery-from-boot.p file so your custom recovery doesnt get overwritten by the stock recovery.

[Q] TWRP: "custom recovery" not working anymore, TWRP not starting

Hi there,
I wanted to install latest CM10.1 coming from 0526 yesterday on my Defy+.
Did a backup with TWRP first.
Then the flashing failed, so I wanted to recover from backup.
Phone now is stuck at Motorola M not booting anymore.
When I enter bootloader (vol down) and want to enter "custom recover" he just jumps back to the same menu. TWRP is not starting.
Choosing "stock recovery" is possible, but if I choose a CM10.1 zip file it's not accepted.
RSD Lite does not recognize the phone when it's in the bootloader menu or in the stock recover menu.
Help is very much appreciated, what can I do?
Thanks and best regards.

Okay, I found out why I couldn't enter flash mode by using Vol+ when starting.
The phone powered already up when I put in the battery, so I always pushed Vol+ too late.
Pressing Vol+ WHILE inserting the battery did the trick, phone went into flash mode and I could re-flash 2.3.6 sbf using RSD lite.
[Idiot mode=off]
Still not sure why TWRP was messed up just by recovering from a TWRP-made backup...
Best regards
Same situation to me.
I opened Terminal Emulator, gained root access
then type below command to get recovery mode
# reboot recovery
Custom recovery not running
I have a similar issue.
I rooted my stock S4 and installed the proper TWRP.
Heres where my situation is a bit different from anything I have seen on the forum threads. All attempts—both hard and soft—to reboot into recovery, all direct the reboot to Odin Mode. Just to clarify I have not flashed any rom custom or stock, the only thing I have flashed has been TWRP and CWM recovery. And I only flashed CWM AFTER the Failings of TWRP.
When I attempt to boot into recovery, it flashes the blue characters then sends me into a Odin Mode loop until I hard-key the "download mode" and select restart to boot the os normally.
my phone works fine other than not being able to flash custom roms, which is a pain in the arse especially with all the s4 Bloatware.
Here's what I have done so far to help myself:
• install CWM recovery
• tried hard-key reboot recovery (power off/ press home/volume up/power)
• soft reboot recovery through both Goo, CWM and ROM Toolbox pro
• removed my sd card and tried reboot recovery
• removed battery and reboot recovery
• emulator reboot recovery
• reboot recovery both with and without usb cable
I looked into flashing stock with Odin but all tutorials i could find were of an older version and I didnt want to guess what I needed to get that to work,
Please let me know if theres anything I can do.

[Q] Help booting into Recovery

Hi guys, I've unlocked my bootloader and flashed CWM from:http://www.clockworkmod.com/rommanager, I've flashed and didn't get any errors, boot to Android and did "adb reboot recovery", I get in a screen with the android with a red triangle, stayed for some mins and nothing, I turned off and boot to Android, turned off again and turn on by Power + Vol -, Select Recovery and samething...
obs: I used this tutorial: http://forum.xda-developers.com/showthread.php?t=2266654 and downloaded this SuperSU: http://download.chainfire.eu/345/SuperSU/UPDATE-SuperSU-v1.51.zip
How can I boot to recovery?
Another thing does SuperSU v1.51 works on Android 4.3?
Thanks
The screen with just a red triangle is stock recovery. Press and hold power and press volume up and you should get the stock recovery menu.
Try flashing CWM from fastboot manually as it's not taking with ROM Manager (which I don't rate anyway)

did you use fastboot flash recovery recovery.img ?
after that you were not able to get into recovery?
Was the 802 ROM a modified stock ROM?
If it was a stock modified ROM then find an original AT&T boot.img, you can download any ATT ROM and extract the boot.img. From there get back into fastboot and flash boot.img
fastboot flash boot boot.img
once you have boot.img flashed you should be able to boot into Android. Do not go into recovery and wipe or format anything.

Can you get into recovery? Which recovery you have? If you can get into recovery, then flash the PA ROM again so you can get into fastboot, download CM for the 800, extract the boot.img from CM and flash that boot.img
turn the device on holding the power down key and power button, as soon as the bootscreen comes up...release the buttons and re press them immdeatley.
this should put you on the recovery screen, hopefully from there you can restore your phone.
cheers.

from fastboot flash clockwork recovery if you are not using it and then see if you can mount USB storage. Not sure if it is in twrp or not. Did you use the CM boot.img from the D800 CM 10.2? It should have boot. Did you wipe system?
