phone stuck on boot animation. - Nexus S Q&A, Help & Troubleshooting

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.

Enter Stock recovery??

Anybody know how to enter stock recovery? button combination?
Ive tried power on plus up, and power on plus down. I would just flash CWM and make it easy, but i might be returning the phone to tmobile for my screen bleed soon and want the phone to remain stock for now.
SO anyone know how to get into stock recovery?
On the dev forum there's an image of the stock recovery. Sorry i'm on the phone
why? what are you trying to do? if you never flashed cwm, vol. down and power will do a factory reset. as of now, there is no way to enter the stck recovery. just a factory reset.

Not true.
I posted a way to get to stock recovery
Download rom manager
Go to settings, SD and phone storage then unmount phone storage
Now
Go to rom manager and reboot into recovery then it takes you to a screen when you hit home and it shows the blue stock recovery screen....
Not sure how to make selections though

[Q] Booting keeps looping, no backup :((

Hi,
please. Help me out. I just rooted my Nexus S I90023. Everything worked fine I flashed new CM9 Alpha19 ROM, but did not do any backup before. I know, I am complete asshole! It's a brand new phone so I thought I do not need any backup while I have no data. But know the bootscreen has just Google logo and lock image. i can get into recovery but I have no backups and other ROMs installed.
Is it brick? ((
go to recovery. (Power button and volume down) once in recovery press both volume up and down at the same time...then do a factory reset-wipe.
If you still need some data from the phone i would just try to wipe cache in recovery and reboot.

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!

So I manage to unbrick my phone without a computer. I already had c11 ROM on it. I forgot to wipe factory and wipe partition. I end up flashing a new ROM on top of my old one. When it reboot. It got suck on the bootload screen. Not actually stuck like just a loading bootload screen. It constantly boot flash on and off. Like the phone is turning off and back on. It never stayed on. So I took out the battery. Put it back in. Tried turning it on again. It did the same thing. So I hold down the power button+ volume up+ home key. This give you the adba to connect to the computer. When it comes up don't press up to connected to the computer. Press down to cancel. Once you cancel it will reboot again and you will be rebooting normally. Don't know if it was a soft brick or a hard brick but it worked..
Oh thanks, I didn't know There was a Volume down button to function as "not to connect" to the computer. Thanks. First I thought you were just posting about your problem. The solution came to me as a surprise.
anytime
No prob anytime.. I wonder if they will continue to build ROM for the SGS3. Because it does have 2gb of ram. Which still have more than some of the new phones. There owners who still love and cherished the SGS3.
OK so found out why it went into a boot loop. Some how I manage to delete stock recovery. While I tried to install twrp. I installed the wrong version and it did not take. So it malfunction causing it to bootloop. I reinstall twrp with the newest verison. It work.. It replaced the stock cwm and place the twrp in its place. Now I have recovery and no boot loop. Problem fix..

So if you having boot loop and can't get to your recovery mode. Download twrp. Go install. Select your device. A list of twrp version will appear. Select the first which is the newest version. Hit install. Once it download. Its ask to install. Hit yes and then it will ask to reboot.. Hit yes. Your phone will reboot into twrp recovery with a new look and touch buttons. Instead of the factory mash up or down and power button for select.

After you done this make sure you have a back up file with this new twrp as your recovery on sdcard. Hit wipe cache,data and dalvik.. Then restore file.. There you all fixed..

This is for those who don't know how to use terminal emulator. Most don't know the commands. But in terminal you can hit su, then grant permission. Hit wipe and it will tell you what choice. Such as data, system or dalvik. But you have to clarify your command. It will wipe you phone and sdcard. Then restore you phone. But it won't restore the boot loop. Cause of the file either missing, corrupt or not there. It will continued to boot loop until you reinsall you new recovery mode. Any question contact me and I will respond back as soon as possible

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
