when you do a cold boot (hard reset) you have to
1. Power off the phone. Remove and re-insert the battery to make sure.
2. Press and hold the middle of the Volume button (so that both + and - are pushed down) and the Camera button. While holding these button also press the Power button.
3. Wait until the screen shows "Cold Boot" then release the Power button only.
4. Keep holding the middle of Volume and Camera buttons pressed until the Welcome screen appears.
This may require some fingering to get it right. If you don't get it right you may accidently enter the emergency download mode.
If this doesn't work you can use the download mode to deploy a NoDo rom that might be available for you phone.

[Q] Help Nexus S Totally Bricked!

Please help if you can, would really appreciate, dont know how to unbick my totally F$$$$### Nexus S Phone.
Even in recovery/fastboot mode on my Nexus S (Vol up+power), I cannot get my system to recognize the device....in fact, even in Windows, I am not able to get the system to recognize my device in Recovery mode/Fastboot mode....the only way it will recognize the device is if it is turned on the normal way, and hangs on the "Google unlocked icon" screen.
Some background info:
My power button recently stopped working...I thought it had to do with the fact that I updated NexusTools (was running a CyberGR rom...cant remember the name...had V4 Ultimate in it (downloaded from Rom Manager)).
So what I did was download/install (from the same developer) their hybrid ics rom....that did not brick it...but it also did not fix the power button...so after not liking the new rom, and the fact that it didnt fix my power button, I reflashed to the original rom I had installed (wiped everything, including doing a factory reset), and it just hung on "Google unlocked icon"
Now my phone does the following:
- First of all, the only way to power the device up is to plug it in (it automatically turns on and tries to boot without me pressing the non-functional power button)
- If I let it try to boot, it infinity hangs on the Google unlocked icon screen
- If I boot into recovery (by holding vol up button and plugging the phone into a power source), it hangs on the recovery screen...meaning the power button, as well as the volume buttons, as well as any buttons are non responsive.
- If I boot into recovery, the device doesnt even register on my system....
What am I doing wrong? What can I do to try and fix this?
I would truly appreciate if anyone reading this has some insights for me.
THANKS!!

yes, sounds like a dead power button(i have one myself).
try going back into your recovery, do a full data wipe(factory reset), then reflash the rom(and gapps). if still nothing, redownload the rom and try again. in your recovery, there is an usb option. use it to transfer your newly downloaded rom from your computer to phone.

Once I am in recovery mode it "freezes" though...as in not even the volume buttons work...they worked fine before, and even work to get into recovery mode...but once there they no longer work...nor does connecting the device in recovery mode to my laptop....so im kind of at a loss, as I cant even use Fastboot/adb to wipe/push anything on the Nexus S through my laptop

im guessing that your using cwm recovery?
give your phone a few smacks on the back near the power button, your phone thinks its being pressed in.

yes, it definitely thinks it is being pressed in...thats for sure...and makes sense...ill try that haha!
Yes latest CWM Recovery...5.0.2 or something like that...just updated that before phone died...

Weird...so i "smacked" the phone a bit...when I do it in recovery mode, it reboots the phone into recovery....so it definitely thinks its being pressed down constantly...but I have found no way to make it "un-pressed"...only briefly by smacking it...

in twrp recovery, theres an option to not use the power button to select(thats what im using), is there a similar option in the newer cwm recovery? tr\y pressing the soft buttons). also, see if sticking a fingernail in between the power button helps, to pull out the button a bit.

After continuingto smack it...as well as "pulling" on the power button, I am not able to use volume buttons and power buttons within recovery...flashing a new rom now...will let you know if that fixes it...otherwise I will try unbickable in ubuntu again and see if that fixes it thanks for the pro-tip of smacking it, haha!

Did factory reset now bricked

So I did a factory reset, the tab rebooted to wipe the device, went to nvidia logo then screen went black, shuts off automatically and I can turn back on just for it to get right past the logo and shut off again, I've tried volume up with power and volume down and same thing happens. Sometimes the power won't even turn it back on for 5-10 minutes. Any suggestions?

Dumb question, but are you sure the battery is charged? I would leave it plugged in for awhile and try again. Then if it still is not booting try to enter download mode while connected to PC. Mine did something similar to this once when I did a factory reset as well. It only recovered after connecting USB to my PC.

I'm guessing you have custom recovery installed?
1. Download the factory image from NVIDIA website (specific to your device version),
2. Go into fastboot by pressing volume down and give a slight nudge to the power button (don't press until the logo comes up, just a quick nudge will do)
3. Unlock your bootloader using the instruction which can be found on this forum (if you have, skip this step) sorry I'm on mobile phone, so a bit hard to do a search for the link with small screen.
4. Unzip the recovery image zip file.
4. While still in fastboot, flash the recovery images using flash-all.bat contained in the unzipped folder.
You will lose your custom recovery and your root, but since you were gonna wipe your device anyway.. let me know if you're stuck somewhere.

I think i might have found fix....
Shut down the device with long press (8sec) Power button
Press and hold Vol down key
Press and release Power key
Device enters fastboot mode
Select Recovery mode option (using Vol up/down for navigation and power key to select)
Device enters recovery mode (after showing NVIDIA boot logo) with Android Robot screen.
Press and release Vol UP + Power button simultaneously
Then select wipe data/factory reset with Vol up/down key to navigate and power key to select
try this but be PATIENT AND wait for it to say erasing then i think ill be normal once its done also just wait with it on the "blank screen" we could have just got ahed of are selves and whent to conclusions and thought it was bricked

Pixel Stuck in Bootloop, ADB Unauthorized, Bootloader Unlocked

Hello, I recently came on a pixel phone to build and use lineageOS on. Upon rebuilding, I believe I performed adb sync wrong the device and damaged system. After that, my adb keys became unauthorized and I am unable to access the bootloader menu(I press power and volume, but phone boots into Bootloop). I tried the steps to get to bootloader menu, but the phone doesn't power completely off, and when I press the power button it gives me the launch screen saying press power to pause/continue boot, not allowing me to go into bootloader
My bootloop goes like this: Bootloader integrity screen(bootloader unlocked, cannot be verified) --> Google loading screen --> Android recovery. This shows 2 options with the message, "Can't load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device". The two options are to try again or data reset.
I press try again, and the same bootloop ensues, sometimes getting to lineage loading logo, but then back to the same recovery error regardless. If I press the buttons(power and vol up), to go into recovery, it just shows an android with a warning sign above it, giving a message saying "Error!" on the bottom. My adb on the computer shows as unauthorized, so I don't know how I can fix this. Google has said the warranty is expired and cannot do anything to help. Ideas to fix? Thanks for help in advance!

Use power and volume down (not up) to go into Fastboot mode. Then flash the stock images

I tried that, but whenever I press any button, the phone is never turning completely off unless it dies. Even after that, it goes to the screen showing the secure boot integrity(Press power to continue/stop boot)
How can I completely shut off the device and restart it? And if system is messed up, will that leave my bootloader intact(I'm assuming so as boot is a different partition?)

Does holding down the power button for 5-10 seconds turn it off? Or if you do that does it appear to turn off and then restart?
If that fails to turn it off, try just holding power and volume down for 5 seconds, and if the screen flashes (goes off and then on) let go of the power button but keep holding volume down and hopefully it goes into Fastboot.
That should work unless you have a dodgy power or volume button. The bootloader is completely separate to the boot partition, and the fact that it's doing anything at all suggests that it's still functioning.
Only other option I can think of is trying ADB commands when it's in recovery mode, e.g. adb reboot bootloader. However, if you have the stock recovery, that may not work.

Thank You!!! It didn't work in the bootloop, so I had to let the phone drain its battery and shut itself off, then I was able to enter the bootloader and reinstall lineage. Thanks so much!

Is ur bootloader unlocked? If so, use twrp to perform a full wipe and install from twrp as well. Of you can't access trwp, and are in a bootloop, do the same thing I did: let the phone lose all it's battery, so it's outta the loop, connect the phone to a charger, then hold power and volume down. This should get you into bootloader mode where you can then use fastboot to flash twrp.

Not able to get into EDL or Fastboot

Hi Everyone,
Recently I have unlocked the bootloader and flashed twrp after upgrading to OOS 13 after that I have not able to access any storage(including OTG) so I had changed the format of disk. Now its stuck is bootloader and show qualcomm icon when starting and just keep on trying to boot(stuck at logo not a loop or anything). I am not able to get into the EDL mode or fastboot for that matter any suggestions
Video is uploaded to show the icon it continues to normal oneplus logo boot and stays there

can you hold vol - and power with it unplugged until the screen goes black, then fast as lightning hold both volumes and plug it in? I used to have this device and I'm trying to remember what I did to get out of that.

I had always waited till the phone got discharged and then tried again EDL used to work when I had the flashboot but now it not a possibility it resumes into the unlocked bootloader alert (sometimes press power to pause or continue to boot) and then logo not matter which combo of the buttons I tried

If nothing works you can always take the back off and unplug the battery.

Doesn't discharging the phone will also do the same or are you suggesting me to go into edl by removing battery cover and plugging in like the old mediatek recovery method

Have you tried unplugging the device, using volume up and power to fully shut off the device, then wait a second, and switch to volume up and down, while plugging in? Important to keep it unplugged until going into EDL.

It's already fully shutoff when I discharge it to recover from the boot animation. The keys combo don't work at only power button work to continue or pause boot
