weird problem trying to unlock nexus s

a buddy of mine bought a nexus s off of craigslist that is constantly force closing when you boot it. it will force close everything then reboot itself. im attempting to unlock the bootloader but adb devices doesnt show the serial number like it does for my nexus s. when i hold down volume up+down and plug in the usb it goes to the unlock bootloader screen but it doesnt give you the option of yes or no. iv posted a picture to show what it looks like. i cant get the phone into download to try to fix it with odin either. any help would be appreciated.
edit: i finally got my pc to recognize it and we now have an unlocked bootloader, but now iv encountered another problem. i downloaded a recovery image and moved it to the tools folder of sdk when i type in the fastboot flash recovery command it responds with error: cannot load recovery.img.

To unlock bootloader, you have to use fastboot, not adb. So the correct command would be fastboot devices
To boot into the bootloader, you have to press volume up + power, not volume up+down and plug in the usb -- that would bring you into the Download Mode instead

i know, i used adb devices to see if my computer would even recognize the phone. i i can get into fastboot mode by pressing volume up and power but cant send a fastboot command to the phone because it doesnt recognize the phone. when i hold down volume up and down to get into download mode it sends me to the screen i showed in the pic. its the unlock bootloader screen except there is no option to click yes to unlock the bootloader. i would love to get into download mode and use odin hence why i pressed vol up and down and plugged in usb, but like i said it sends me to the unlock bootloader screen.

Before you try to unlock the bootloader I would flash the latest stock rom and see if it boots properly.

Try one of these recovery images:
http://forum.xda-developers.com/showthread.php?t=988686
The full command is
fastboot flash recovery recovery.img
(make sure your recovery image file is actually named recovery.img)

If 'fastboot devices' returns your phone's id you can flash a custom recovery. Otherwise get a full _signed_ stock rom and flash from stock recovery.
Did you install all drivers? Deinstall existing and use either pdanet or sdk build in program to get them. You need like 3 different ones.
Try locking unlocking bootloader again.
There's always the chance you got a defective usb connector.

cant't access bootloader (tried everything)

hi all
I have strange problem
I can't access bootloader I tried these ways:
A- vol down + power = nothing just boot normally
B- in fast boot usb: fastboot reboot-bootloader = nothing still in fastboot
C- in extended power menu : restart - bootloader = fastboot
excuse my poor english
please any help

dude you are in bootloader ..when connected to pc ..it will go to fastboot usb (infact fastboot is part of bootloader)
1.you need to remove battery ,then reinsert it then do volume down + power ..or uncheck the fastboot in settings->power then volume down + power
2.obvious ..as long as connected to pc ..it will be in fastboot
3.when connected to pc ..it happens

This is not my first time to install radio
I didn't ask before reading and searching
Still waiting help

Fastboot is/is part of the bootloader. From fastboot you have the 'Bootloader' option, which will load the HBOOT and thus scan for a PG58IMG.* on your SDcard.
/thread.

The funny thing is when I push vol down it scrolls up
When I push power nothing happen
In other word when I highlite bootloader then push power to choose nothing happen

If you want to go to bootloader only then.. Do this.. Type adb reboot bootloader from phone connected normally then once the coand is done.. Immediately remove the usb cable.. That will take you to hboot only

**URGENT** Semi-Bricked HTC One S

Hello XDA, this is my first post so please bare with me.
I own an HTC One S and I've had it for about a year now. I recently rooted it about 3 or 4 days ago and everything was going smoothly, I pushed Superuser.zip onto the SD card and it worked fine, then I figured I might as well install a ROM manager so I got one off the Play Store, then I downloaded Clockworkmod Recovery and when I booted into recovery to flash it, the phone screen went dark, and wouldn't turn on. When I plugged the phone into the charger, the LED came on and stayed on even if I disconnected the phone. If I hold the power button, the screen flashes very quickly, the LED goes off and about 10 seconds later, the LED comes back on and it's back to the black screen. I had the same problem earlier but I pressed a combination of buttons (I don't remember which ones) and the screen came on so it's not bricked badly, I need help urgently.
Thank you in advance.

1. Go to bootloader (holding power button and volume down button)
2. Find out if it's locked or not.
3. Find out if your phone is S4 version (VLE PVT SHIP) or S3 version (VILLEC2)
4. Relock bootloader if unlocked:
1) Connect your phone to your PC
2) Make sure you have installed HTC Sync (drivers)
3) In bootloader with volume up/down button select "fastboot" then click the power button
4) Make sure it says "fastboot USB"
5) Download the file from the attachment (fastboot.rar)
6) Make a new folder on your C drive called fastboot
7) Extract the contents of fastboot.rar to your fastboot folder (the 4 files from fastboot folder)
8) Make sure your phone is connected to your PC, and you are in fastboot mode
9) open cmd and write:
Code:
cd/
cd fastboot
fastboot oem lock
10) Your phone is now Relocked!
5. If your phone is VLE PVT SHIP (S4) download this RUU ww w.androidruu. com/getdownload.php?file=Ville/RUU_Ville_U_JB_45_S_HTC_Europe_3.16.401.8_Radio_1.11.50.05.28_10.27.50.08L_release_301814_signed_2_4.exe
I recommend you this one but you can choose any other from ww w.androidruu. com/?developer=Ville
OR
If your phone is VILLEC2 (S3) download this RUU ww w.androidruu. com/getdownload.php?file=VilleC2/RUU_VILLEC2_U_ICS_40_HTC_Europe_1.11.401.110_Radio_16.12.20.02U_16.05.20.16_M2_release_263510_signed.exe
I recommend you this but again you can choose any other from ww w.androidruu. com/?developer=VilleC2
(remove the spaces from the links!)
6. Run the RUU
7. It will automatically detect your phone (if in Fastboot USB mode)
8. It will reinstall the stock ROM to your HTC One S, while it will be installing do not touch your phone, and don't even try to disconnect it! You could hardbrick it! You have been warned

Hi, i have the same exact problem. The phone like what OP mentioned, can't be turn on, just a quick flash of white light and nth. Power Button + Vol Down doesn't help either. I'm guessing my phone has the Hard Brick thing. So far, Riff Box JTAG is the ONLY way for this. Hope my country has one and KNOW of one.

[GUIDE] How to Unlock Bootloader and Install TWRP

First, you’ll need ADB and fastboot, which can be downloaded here. To set up ADB, go to Settings/About Phone/Software Info and tap on build number until you get a toast notification saying “You are now a developer!” You will now have a new category in Settings called Developer Options. Go into developer options and enable USB debugging and OEM Unlock. You won't be able to turn it on if your phone is plugged in to your PC. Once you've turned it on, go to your PC, open Terminal or Command Prompt and type “adb devices”. Then plug in your phone and hit enter. You'll get a prompt on your phone to “Allow connection​s to this PC?”. Check Always allow and Allow. Now run “adb devices” again. Your device should now appear in Terminal.
If you have a SD card, download the latest zips from here and here onto your​ SD card. It'll save you a step later on.
Then you'll need to reboot to fastboot by holding down VOL- and plugging in USB while power is off. Alternatively​, you can type “adb reboot bootloader” in Terminal or Command Prompt.
Next, you'll need to unlock the bootloader. Bootloader unlocking​ will factory reset your phone! Once you're in fastboot, run “fastboot oem unlock” in Terminal or Command Prompt. Now the bootloader is unlocked.
Now it's time to flash TWRP, a custom recovery for Android. It's going to be the way you install custom ROMs and add-ons. Download Official TWRP here. Once you've extracted​ the recovery.zip, run this command: “fastboot flash recovery path/to/recovery.img”. Once the file has flashed, disconnect the USB cable and battery. The next step is important! You're going to need to boot into TWRP for the first time. With the phone off, hold down VOL- and press power until the phone vibrates and the LG logo appears. While still holding down VOL-, release and immediately press and hold power. You should now be at a white screen that says “Reset all data and restore to factory settings?” Use the volume and power keys to select yes and yes again. If you've installed​ TWRP successfully​, it won't actually factory reset your phone. Now you should see the TWRP screen. If you don't see the TWRP screen and instead see a floating ring that says “Erasing”, don't worry. Let if complete and try flashing TWRP in fastboot again.
In TWRP, you'll be greeted by a screen that says “Swipe to allow modifications?” Swipe it, then go to the Wipe tab. Go to Wipe, then Format Data, then type yes, then go to the Reboot tab and select Recovery to reboot into TWRP again. If you're prompted to install the TWRP app, don't bother.
Once you've rebooted into TWRP again, it's time to disable encryption​ and root the phone. Download the latest zips here and here. Skip downloading them if you already put them on your SD card earlier. On your PC, push the files to your phone using the command “adb push path/to/file.zip /sdcard/”. You can drag and drop the file into Terminal or Command Prompt to copy file path. Then go to the Install tab in TWRP and select the no-verity-opt-encrypt.zip, tap Add more zips, then add the root zip, then swipe to flash. Let the zips flash, then tap the Reboot System button when it's done. Your phone will take a little longer to boot and might reboot a couple times.
Once you're back in the OS, go through the setup wizard. Set up Magisk. If you stay on stock, you should install an app like Quick Reboot Pro from the Play Store to make it easier to reboot into recovery. Now reboot back into TWRP and go to the Backup tab. If you have a SD card, set it as the backup location. You can enable compression if you want. This will make a full system backup that you can restore from as long as you have TWRP. If the backup takes up too much space, you can put it in Google Drive or your PC later on.
You are now ready to install ROMs!

My device will not start boot loader with command "adb reboot bootloader" or with the method of holding volume down and pugging it into the PC, it just restarts and boots like normal. i cannot even get to the stage to use the command "fastboot oem unlock"

Please explain more in detail so you can be helped better In what ways? What are you doing to get into bootloader mode? I've never had any issues on my T-Mobile Stylo 2 plus. Are you trying to get into bootloader using buttons manually or through twrp or adb?

You hold volume DOWN and power then soon as screen comes on and you see LG you let go of the power button and then immediately press power again and you never let off volume DOWN. That doesn't work?

Hey there, I've got the LG K530F, is there any chance of unlocking it? I looked up the LG developer website and it's not listed in there, filling that form will just lead to a popup regarding that. I thought about downgrading it back to MM (Android 6.0) using the K350F10d_00_02221.kdz firmware package aiming to be able to run fastboot oem unlock, but I'm afraid of getting it bricked. Anyone tried it? I recall doing something like that to unlock the LG Optimus L9, but that one was way older and had much weaker security measurements.

Can't get into Bootloader
Hi i have a LGL82VL and when trying to use adb reboot bootloader it just restarts, And when using Vol Down and Power it just comes to the factory reset page (Hard Reset)
Any ideas on how to get to the bootloader? i checked with fastboot devices while on the hard reset page and got nothing. Any Ideas?
