[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

Power Button and Volume down button both stopped working

I've had my phone for about a week now and had this happen this morning. Power button wouldn't turn on screen/do anything and volume down wouldn't do anything. Had to use the home button to get the screen to respond. After holding down the power button and volume down I was able to reset the phone and the issue is no longer present. Should I just assume this was some kind of software hiccup or should I go the route of trying to get it replaced for being defective? Anyone else run into this issue? Any help would be awesome. Thanks guys.

I had an issue with my power button failing to respond. Because of it I couldn't restart my phone (and we can't get any restart apps without root) so I had to use the built in scheduler to force restart my phone.
Found that in settings -> backup and reset -> Auto restart. Supposed to be used to "optimize your device by restarting it automatically at set times" :/

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.

Stuck in Safe mode, volume button issue

Hey everyone,
issue: Nexus 5 always boots into Safe mode
-volume button is stuck pressed but physically it is fine, I even removed the whole button and tried to turn it on, same issue
-when I turn on the device, bootloader appears with cycling options (i.e volume button issue)
-I swapped the whole mother board to another one, problem solved (borrowed from a friend)(gave it back)
-did a factory reset through stock recovery
-bootloader unlocked, TWRP installed, rooted
is there a way to "Force" your phone to boot normally?
or is there a way to disable safe mode?
or is there a way to disable the volume down button itself?
[Update 14 Sep 2017]: found a work around, tapping the volume buttons rapidly (alternating) while boot up, this fixes them temporarily, been 24 hours now with no issues
thanks

Blank Screen Bootloop?

Hi Everyone,
Phone decided to randomly turn off (at around 80% charge) and now won't boot. Have tried all the basic TS guides.
have tried:
-Charging - no on-screen displays
-Holding power button for various intervals
-Button combinations (Power + vol up....etc)
Connecting to PC gives me an indication that it has detected a USB connection, then consistently after ~40s I get the disconnect notification sound. Then off for 20s and the the cycle repeats.
I'm assuming it is stuck in bootloop for some reason but still nothing from the screen.
Phone hasn't been dropped, rooted, is running stock ROM etc...
any ideas?

Assuming the bootloop isn't caused by hardware failure then you can try forcing your phone into its Recovery mode by holding down the power button and volume down button simultaneously. From here, you may be able to roll your phone back or restore a previous backup. However, this often results in data loss, which isn't ideal, so you might have to weigh up your options.
If this doesn't work, you'll need to enter your smartphone's Safe Mode. When your phone is booting, and you see the manufacturer's name appear, press and hold the volume down button to put your device into Safe Mode. Here, you can follow prompts to hopefully remove whatever program, app, or software updates forced your phone into a bootloop.

It won't boot at all, the screen doesn't turn on. But surely something like this doesn't just randomly fail

My recommendation: take phone to authorized service center and let them try to fix it.
