[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!

see if you have free space on your phone for the error , as for the booting in to recovery :
1.remove battery
2.reinsert baterry
3.hold volume up + power
4.chose recovery (vol up/down to scroll and pover button to select)
4.wait for phone to boot in to recovery

Fastboot boot recovery name of recovery.img
If you unlocked the right way and not some lame one click crap.

You can try wiping data/ factory reset. Boot into Recovery Mode by holding down Power and Volume Up buttons together until the screen turns on. When the Samsung logo appears, let go of the Power button but keep holding down the Volume Up button until the device boots into recovery. In Recovery Mode, select Wipe data/Factory reset and select Yes on next screen. Select Reboot system now to reboot the tablet

Another boot loop

Tried to change roms and somewhere in the process it got to the Samungs logo and wouldn't continue. I've tried changing recoveries and roms with the same results. I even tried CynagenMod rom and it just changes the logos of the boot screen. I can get into recovery and into download mode. Anyone have any ideas? I'm running out.
Please help!

I have this same problem
I have the N8013 version.
Installed a rom then tried to revert back to previous rom. and got stuck on the SAMSUNG logo. Can get into Download mode, and Recovery Mode.,,but nothing helps. I have tried several methods:
1. ODIN- CWM and TWRP recoveries, and a number of stock and custom roms floating around the troubleshoot forum...got" PASS" on the ODin after attempting to install stock tar images but tablet still gets stuck at SAMSUNG
2. Sideloads of zip files..I get 2 different errors that after doing research seem common on the websites. I suggested to use touchwin recovery instead of CWM, CWM gave another error. .Long story short sideloading is not working either.
Any thoughts, suggestions...help please!

Thanks for the reply....
I tried what you suggested:
wiped data/factory reset
wiped cache
wiped dalvik cache
Then installed the following tar file: N8013RootInjectedSystem from http://forum.xda-developers.com/showthread.php?t=1831152&page=4
Got stuck on the Samsung screen.
From my experience you wipe before installing the rom.. Correct?

I installed: CF-Auto-Root-p4notewifi-p4notewifiue-gtn8013.tar.md5 via Odin, the process passed, and tablet booted into stock recovery.
Did a factory reset from stock recovery and attempted to reboot, but still got stuck at the Samsung logo.
Any suggestions of how to proceed from here?
Any help or suggestions would be appreciated. I do have 2 backups but they are on my external microsd,and will not load in stock recovery...not even able to access my micro sd from custom recoveries.
Any help or suggestions would be greatly appreciated.
TIA
KL

Fixed following these instructions: http://forum.xda-developers.com/showthread.php?t=2108145
The noteable suggestion seemed to be to format everything except external memory...
the only problem is now i am unable to view microsd....but i am happy happy happy
let me know if this works
HOW TO FIX A STUCK BOOT SCREEN ON GALAXY NOTE 10.1 N8013 4.1.2
1.) Download ODIN (just google it)
2.) FLASH ClockworkMOD (CWM) using ODIN to Device (just google it)
A.) Before pressing "START" Uncheck all options ( Auto-reboot, F-reset (re-partition should already be unchecked etc) Just hold the power button device to reset, it will reset on it's own upon start up
4.) Download Firmware Hotfile Linked By the Beautiful Samir who commented on this thread (just search for him). Make sure that fireware is designated for your particular device. No Samsung SIII firmware for Samsung Galaxy Note 10.1.
A.) Use the "Save to" Option not the "Open With" option...It's just better
5.) Enter Recovery Mode (CWM Mode) on device using the Power + Volume UP key
6.) Factory Reset Wipe
7.) Wipe Cache
8.) Advance Settings - Clear Davlink Cache & Fix Permissions
9.) Mounts & Storage - Format all except your external SD card (be careful and watch what your doing don;t want to delete anything else by mistake..cause you will be really..cough..upset)
A.) be forewarned that after these wipes you won't be able to get past the first Samsung logo screen, it will just remain there on the screen but have no fear it should be fixed when you download the Firmware. KAY. breathe easy.
B.) i mention this because my problem was that i was getting past the first Samsung logo but not past the second one, in the sense that it wasn't even appearing on the screen.
10.) Make sure that your USB drivers for Samsung are working, you can get the driver from Samsung site (Google it) or use KIES (Google it)
A.) if you use KIES i advise you to download it, get the Samsung USB drivers from it, then go to control panel on your desktop and Uninstall it, you can download it again later when your Note is working again but it seems to cause problems with ODIN, better safe than sorry i always say
11.) The Firmware can be a particularly long download, but once it is done and you have extracted it to a folder using WINRAR (remember the name of this folder) make sure that it is saved to your computer then shutdown and restart your computer
12.) Now with your newly restarted computer.........
1.) Open ODIN
2.) Put Samsung Note 10.1 into "Download Mode"
3.) Connect your Note to Computer using USB, it should make the ID:COM turn yellow
4.) Uncheck auto-reboot, F-reset etc
5.) go to PDA and look for the folder that you placed your firmware in :KIES_Blaahblaahblahh_blaah
6.) Press START
7.) you should see a download begin both on device and within ODIN....PASSSSSS (Green Box)
8.) Reset Computer Manually by pressing the power button
9.) turn back on Galaxy Note 10.1 and you should be all set
a.) don't be scared after you turn on your note and you get the Samsung logo and then the little android robot downloading some stuff (that is supposed to happen)

[Q] HELP !!!!! UI system stoped working after lollipop update

$/?/)$?*/"$)*?"%?""?(*
stupid freaking company.......
I got the update OTA few minutes ago, downloaded the update then applied and now my phone is not working anymore....
All i get is iu system stopped working
i have a nexus 5 stock non rooted
i tried to reboot the phone several times
Also tried volume down and power, but the only options i have is:
recovery mode (wich do nothing).
restart bootloader(wich do nothing)
start
or exit
Im not even able to go back in my options to do a factory reset
help me please and fast before i throw this phone into the wall
EDIT:
after calming down a little, i found how to do a factory reset in the recovery mode, phone is formating /data atm

You can factory reset by booting to recovery. So go back to the bootloader (Volume down and Power). Then you should see an android with an exclamation mark and the words "No Command". From there, hold the power button & tap Volume UP one time. That'll boot you into recovery mode.
Now I know performing a factory reset from within android will completely wipe the phone, I'm not sure if it's the same with a stock recovery. So if I were you I would ADB pull the contents of your /sdcard before performing the factory reset. After that just use the volume keys to navigate to perform factory reset and power key to select.
It also might be worth a shot to only wipe cache the first time you go to recovery and then reboot and see if that worked. If not, pull your data to PC and then factory reset.

Calm down more first

thanks,
well i went directly to factory reset, we'll see.
when i changed from my n4 to n5, i had a backup and i also have a backup from my email account so i guess i wont loose everything
the only "customisation" i did was to change some icons on my N5, i dont understand why i got that iu system error

Sure, no problem.
Hopefully the factory reset fixes it for you. If not and you need some more help installing the factory images via fastboot, just holler.
