[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

[Q] Odd Galaxy S3 Power Issues

I honesty don't know how to describe my problem so I guess I will just tell you whats happening and what I know about my phone.
My phone:
Unlocked Verizon Galaxy S3 running CM for recovery, and CyanogenMod 10 for the ROM (Updated with Odin from Jelly Bean).
The issue:
1) Whenever I press the power button the phone completely shuts off. It doesn't just go to the lock screen, it turns off.
2) The phone will not always turn back on.
3) 85% of the time when it doesn't turn on, it boots into the first splash screen and turns off.
4) When I try to put the phone into download or recovery mode the first screen will pop up for about two seconds and then the phone will turn off again. The phone will either shut down on the cancel/download screen for download mode or the first splash screen with the blue text at the top for recovery mode.
5) The other 15% of the time it will reach the CyanogenMod screen, freeze, then shut off.
6) When I put it on the charger, the stock charging icon pops up but then the phone stops charging and shuts off. (It will charge correctly some times)
These things don't just happen if I press the power button. I used a custom app to turn the phone off without the power button and the problems still occurred.
Things I've tried:
1) Replacing the battery.
2) Switching chargers.
3) Leaving the phone on the charger for a while.
4) Taking the battery out for extended amounts of time.
5) Just leaving the phone alone for a while.
No, the power button isn't stuck... I don't think it is
I am aware that the motherboard might need replaced. However, most of the cases I read about involved the phone not turning on/charging at all. If I could get the phone into recovery mode I would clear the cache and see if that worked, if not I would just factory reset the phone. If I could get into download mode, I would flash a stock firmware and be done with it.
This is my second android phone and I've never had this problem before. I did my experimenting with my old Motorola Droid so I could make sure I knew what was safe with my S3 but apparently there is something wrong.
I greatly appreciate any and all help and please do help me
[EDIT #1]
I began hitting the power button against a hard surface and 1 out of 7 times it works. Perhaps the button is stuck.
[EDIT #2]
I am now able to press the power button without the phone turning off. I will still make a back up and sync all of my important media and prepare to have to factory reset and flash a new ROM.

[Q][XT1032]Bricked Moto G With NO USB Debugging

Won't Properly Turn On. Can't get to bootloader.
--+ How?! +--
1) Updating to lollipop (power off)
2) Goes To TWRP Recovery
3) I Power Off With No SuperSU
4) BRICKKKKKKKK
--+ Signs Of Life? +--
The phone seems to be woking but I can't see the display....... I think I can get into bootloader mode and press power because about 2 minutes later the notification lighting comes on and the phone makes the beep-beep-bee!
They say not to panic... BUT IM PANICING. Please Help Me And My Spelling

1. Plug it into the charger
2. Hold the VOL DOWN key
3. While still holding the VOL DOWN key, press and hold the POWER key
4. Hold both keys down for over 120 seconds. This is more than two minutes and will seem like a long time. You might want to time yourself to make sure you hold it longer than two minutes.
5. After holding the keys down for more than two minutes, release them.
6. The Flash Boot screen will display, and the Normal Reboot option will be highlighted
7. Press the VOL UP key and the device will start a normal reboot.
If you have tried the above and it didn't work, try this:
Plug in the phone for 15 minutes.
Proceed to Step 2 above.

Did this happen without warning? Were you running stock or custom ROM?

S8 Plus Recovery Auto Boot

Hi guys, this is my very first thread so here goes nothing,
I recently damaged my S8 + power button and it is no longer operational, however i have been able to boot to download mode and reset device after it going flat and not turning back on and staying in a bootloop while plugged in. Any way so my new problem is that it went flat again and i plugged it into charge and it automatically boots into recovery mode and when i manage to get it into download mode pressing volume up or down does not work. Any way to fix this and get my phone back up and running?

I can definitely see that being a ***** because you need the power button in sequence with Bixby and a vol button to get to download mode or recovery. Id prob root the phone and install quick shortcuts app that gives you on/off/reboot/restart/ options it might help you. But replacing the power button is a simple procedure and I'm sure it's very cheap to. Id fix that button and problem solved.

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.

Click to expand...
Click to collapse
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.
