Quick help, device stuck at <!> logo

Hi guys, i'm new to fastboot so pardon me for this noob question. I have root and the latest clockwork flashed through ROM Manager. The issue is that I don't have a nandroid backup yet, so I thought it was a good thing to do. I did the following:
1 - entered fastboot mode (power + volume up)
2 - selected recovery
3 - phone rebooted and now is stuck on the exclamation + robot logo
How do I proceed to reboot phone or enter clockwork?
Thanks.
Edit: Well, I figured how to bring up the options and reboot the phone(turns out it was almost like on my previous phone lol). Still, for some reason I could not boot into clockwork until I re-flashed it using ROM Manager. I think it's the second time my clockworkmod gets messed up and I have to re-flash it. Anyone knows why?
Edit 2 :I just made a nandroid backup and rebooted the phone. Then I turned it off, booted into fastboot mode> recovery and ClockworkMod was gone again. Can someone help me figure out how to solve this? :|

the stock 2.3.1 rom has a script that runs at startup that will replace the recovery back to stock at every boot. /ect/install-recovery.sh
if remove or rename it, it won't do that anymore.

Moved to Q&A

! screen is the stock recovery.

Again, press up and power together real fast.

[Q] How to hard reset Nexus S

hi all
i am trying to do a factory reset to my nexus S but i faced some problems, the phone cant be reset to factory settings. my phone is on 2.3.4 and is rooted
i had tried the following steps
1) going to Settings>Privacy>Reset phone
after i confirm to wipe everything, the phone rebooted and it will stuck at the "Google" logo (in words) with the fastboot unlock logo at the bottom. i took off the battery to shutdown the phone (anything i press at this moment does not get any response from the phone) and start it up again. once it is started (it get pass the google word logo if i do it this way) all my application and even my themes are still there
2) shutting down the phone. press volume up + power button. choose recovery
same thing happen as above. it cant get pass the google word logo and once i restart the phone by plugging out the batt, it went back to previous state without wiping anything
i search online guide and also youtube video and all of them shows that the recovery will bring you to a android with a exclamation mark (in the triangle) but i cant get to the screen. i had left my phone there for 30 minutes but it is still stuck at the google logo.
Please help

thanks for the feedback. now i am trying to flash it but i faced "adb device not found" error

ok done
managed to flash it back to an older version and everything works now
thanks a lot for your help! cheers

Make sure to update it eventually because you could run into issues when flashing stuff if your recovery isn't up to date.
No problem!

phone stuck on boot animation.

so, i just want to flashed a new rom, then i reboot in recovery, then i restored my data. at some point i saw a text shows cache.img was not found. then i reboot the system, the phone just stuck on the boot animation. please help. urgent

Which ROM did you flash? Did you flash gapps?
What are you doing when you say get into recovery and restore data? Are you trying to restore last ROM's /data from recovery?
If yes, then that's the reason you are stuck at boot screen. Factory reset &flash the ROM again and let us know if you are able to boot.

Remove &replace battery. Press volume up button, then press power button along with the volume button. Keep holding till you get the fast not screen. Use volume to scroll and select recovery. Press power button to get into recovery.

Stuck on boot

Hello! I unlocked bootloader succesfully, flashed philz recovery and everything was ok until i flashed latest CM snapshot (previously was on stock vanilla). Now im stuck at google logo and cant do anything! Anyone got any idea whats going on?
P.S. It seems i cant get into recovery, tried holding the power button, but phone just tries rebooting. Same for holding Volumeup+down+power...

Flash stock image in fastboot and start again

I'm guessing you didn't wipe everything before flashing CM??
1. Switch off your phone completely.
2. Hold down Power+Vol. Down till you enter the bootloader.
3. Go to recovery and wipe everything(system, data, cache, dalvic)
4. Flash the the rom.zip and gapps.zip and reboot!

Problem while rooting

I tried rooting my brand new Mate 9. I unlocked the bootloader, but the wipe that followed failed for some reason. In the eRecovery there's no option to Wipe Data / Factory Reset and when I try to log in at the start screen, the keyboard is not showing up, so I can't even log in. Tried wiping through ADB, but it doesn't even see the device. Any other way to wipe it, so I can proceed with installing TWRP and rooting this sucker. Thanks in advance!

You can boot to fastboot and flash twrp.
While the usb plugged in,hold volume down and power, when the phone vibrate remove power button and keep pressing volume down.
For stock recovery, remove the usb,hold volume up and power and when you see the logo, remove power and keep pressing volume up.
You can copy a keyboard apk on ur sd card and install when you are in the system,just skip the log in screens.

Thanks! I managed to install TWRP and boot to it to do a factory reset, thinking that it will resolve my login issue. Now I'm stuck in bootloop.
And if I try to boot into TWRP again by pressing Volume Up + Volume Down + Power it boots me into eRecovery that wants to perform an update, which after 5% fails saying: The update package does not exist.
So I can't even get back to TWRP nor the system.
Any advice to resolve this?

well to boot into recovery just use vol up+power and release once u see the huawei logo.btw when your factory reset fail during unlocking BL you can manually boot into the system and reset thru settings again.

Never do factory reset via twrp. It does not support huawei's data partition.
To avoid bootloop, just flash stock recovery and do factory reset with it. You need flash additional stock zips to restore additional apps and themes.

I had exactly the same problem as you. After rooting and start wipe, the factory reset seems had not finished well and the phone booted to lock screen with password field, but without keyboard...
Only procure that worked for me was rebranding the phone and installing another full room using Funky Huawei. Yes I know it is a paid service but I believe you will be happy to know it can help you.
Good luck
