[Q] Samsung Nexus s hard reset dont work

hi guys,
i just god nexus from a second hand store. i want to hard reset it but it does't.
it is stuck in the screen where the little green guy with the triangle with an exclamation mark next to it. please help.
is there a way to load the factory rom manually?
(i know how to jailbrake and downgrade an iphone so this should not be so hard)

Hold volume down and press on once you see menu with recovery
press volume again and you will see option for clear storage - thats what you want

that is what i have done already. but why is the mobile preventing me from hard reset ?

I have been hanging around the XDA forums (as well as every other forum I could think of) and have been unable to solve my re-set problem.
I got my Nexus S about a week ago and decided to unlock it. That went well, no problem. Then I decided to root using Superboot - that did not go well. Now my phone is unresponsive, just sits on the Google name with an unlocked padlock on a black screen. I can get into fastboot mode by using the volume up and power button if I do this right after replacing the battery. I cannot seem to go anywhere else. Once I got into a menu that would let me install from sd card, but none of the options would install. I followed the following directions to see if I could do a hard reset:
Hard reset Nexus S using hardware buttons
This option is recommended if you are unable to access the options via the Android OS.
1. Turn the phone off by pressing and holding the Power button for about 2 seconds, the tapping Power off. Alternately, you can pull the and replace the battery.
2. Press and hold the Volume Down button while pressing and releasing the Power button.
3. Continue to hold the Volume Down button until you see a menu appear.
4. Now tap the Volume Down button to scroll down to the Clear Storage option.
5. Press the Power button to select Clear storage.
6. Press Volume Up to select Yes.
After a few minutes the hard reset process will be completed and you can reboot your phone to factory default settings.
I never get to the clear storage option, although I have tried data/factory reset and wipe cache. I can get to the android with the triangle and exclamation point but that will just sit for ever, and removing the battery at that point and then rebooting does not work. It just takes me back to the Google and the unlocked padlock. FWIW - my phone updated right before I unlocked it. I don't think it is bricked, but I sure can't get passed the Google name or the Triangle/android.
Thanks for any help.

I've the same problem now - did you ever resolve yours?

Here is how
Power off by removing battery
Hold vol up not down and power,
release power and you get Fastboot mode
vol down to recovery and click power
You get the screen with Android + triangle
Click up and Power again for few seconds
you will get the 'Android Sys recovery'
However if you have my problem 'error in loading the built in SDcard memory this wont help.
The only way i managed to get it to work some times although not now, is to reboot the mobile while it is connected to a PC, and load the PC at the same time.
However this time i am stuck at Google screen

Bootloop can't get into recovery

I am running Cm11 nightly , can't remember the day i think it is 2/21. Well randomly today, the phone rebooted and went into a bootloop. I am not sure why it is doing this now. But even if i remove the battery, and replace it the phone will bootup automatically and continue the bootloop. I can not get into recovery, just Odin. I have read that people have been having trouble with the power button sticking, can anyone confirm this? Any other suggestions?
Thanks

Try volume up + home + power to get into recovery. When you see the blue text in the top left corner saying "rebooting recovery" let go of the power button but continue to hold home and Vol up

If I do this, I see the blue text in the top left but then I get the Samsung loading screen and then it shuts off and reboots.

another option if you cant get into custom recovery is to flash it with a stock rom using ODIN, you will lose everything but it might be your only option as to recovering your phone.

I have figured out that it is a hardware issue. I can boot into the phone if I continuously press the power button as it is booting up. But once it gets fully turns on, the power screen will constantly come up and eventually the phone will just reboot and start the whole process over again. From what I can see, the power button circuit is stuck in on I believe.
Thanks for all the suggestions guys. Looks like I am just going to have to get a replacement.

[Q] HTC ONE SV "Lock screen common control has stopped unexpectedly"

Guys, i have done everything i could to try to fix this problem. But my phone always has popups saying "Lock screen common control has stopped unexpectedly. Would you like to send HTC a report blah blah" I DONT UNDERSTAND WHAT'S CAUSING THIS. I even reset the phone. Also, when i press the lock button after the screen is off, there is no lock screen. It's like a plain wallpaper with the pull down notifs. So i have to pull down the notif, press settings and then click the BACK button just to get to the home screen. Along with this problem, when im in any app and i press HOME button, it's like my homescreen is always resetting. And then the pop-ups come back again. I really need your help guys. Hoping for your intelligent responses.
WHAT CAN I DO?

did you modify anything, root ? unlock etc ?
if not, you need to deep reset you phone from recovery mod.

No root. Now i cannot open my phone. The lock screen is absent, just wallpaper and notif bar. So icannot put my pattern password

Reset/format your phone using recovery mod.
if you cannot operate your phone, just put out the battery, & put it back in, start the phone.
Press and hold the VOLUME DOWN button, and then press and hold the POWER button.
Wait for the screen with the three Android images to appear, and then release the POWER and VOLUME DOWN buttons.
Press VOLUME DOWN to select FACTORY RESET, and then press the POWER button.

Now the problem is...
I did reset it. And when it turned on, everything stopped working. Like ALL APPS. Popups were flooding. "HTC sense has stopped working". So i cannot do anything, so what i did was I restarted the phone. And voila! IT IS STUCK ON A BOOTSCREEN LOOP. Bootloader's option now is to only REBOOT. But rebooting only makes my phone go into bootscreen loop.
NOW I CANNOT FACTORY RESET/CLEAR STORAGE/ETC. I can only REBOOT. So my phone is practically useless now.

[Q] Getting to fastboot without a full boot first

Hey guys
This might seem basic. Of course I can use adb or the buttons to get to the bootloader/fastboot. But occasionally when I'm messing with my n5, I do something that forces a reboot, or maybe I accidently hit the wrong key, or don't do the buttons right - now it's booting up, but, as often happens at these times, now you have to wait for the applications to 'optimize'.
That takes a good long while with 200+ apps! I know I can hold the power and force another reboot, but I can never seem to get it to go to the bootloader while forcing a boot by holding the power/vol+/vol- .
Am I missing something, or is there no way to "abort" a boot, and somehow get to fastboot mode ?
On my old phones, I would pull the battery, jumping straight to "power off" mode, then hold the vol and power like usual and be off to the races.

To force a reboot into fastboot mode, hold Power + Vol down. You can do it whenever you want.

That's ^ the procedure... For me the easiest is to hooks power to force reboot once it vibrates and starts to go black let go of power and hold volume down to get into bootloader.

My S7 Edge is Constantly Rebooting And Nothing Works

The problem started when I was on my bootloader that simply said "Downloading Do Not Turn Off Target" and I held the power button down to reboot since I didn't see any other way to cancel that screen. From then on, my phone kept restarting over and over again. Basically, it shows the "Samsung Galaxy S7 Edge" logo then turns off and shows a blank screen for two seconds then turns on again repeatedly. If I hold the power button, volume up and home button or just volume up and home button, the phone states "Installing system update" on the screen and goes to the menu that allows me to reboot the phone, clear cache, shut down, factory reset and so on. I tried factory resetting and clearing cache over and over again with no luck. I tried to install custom firmware by holding volume down, power button and home button and going into the bootloader and using odin but still no luck. Every guide suggested that the phone has a stuck power button but the tap methods don't work and I'd like to confirm that's the problem before I take my phone apart to replace that power button.
The thing that confuses me is that when I go into the menu with the options for rebooting, clearing cache, etc. the power button works fine. Whenever I want to shut down the phone, I can click the volume up and select the "Shut Down" option and then clicking the power button to confirm and it does shut off the phone. How would the power button be the issue if it works fine afterwards?
So would the conclusion be to replace the power button flex or is it a software issue? Or is my phone bricked after having it for three months?
(The problem's lasted for two days now)

Sorry, wrong thread.

Have you tried flashing the STOCK firmware via Odin or SmartSwitch?

Yea, stock firmware should do it. If you can get into recovery it's definitely not your power button.
