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.

stuck on white HTC Screen after installing custom rom

I have a problem with my phone? When I try to reboot it just stays at the white HTC screen. If I wait till the battery is completely drained and plug the power in, it boots perfectly.
Did I do something wrong with my setup?
This is how I rooted and unlocked my bootloader yesterday: http://forum.xda-developers.com/showthread.php?t=15251

bump, this is quite frustrating

I think I didn't do this:
But now my phone is stuck on white screen and I don't know how to boot into recovery. Do i have to wait till the battery is completely drained?
-edit-
Thanks guys, problem resolved by pulling battery out during the 3 sec window after rebooting with volume up/down button and booting into recovery afterwards.
Then used ''fastboot flash boot boot.img'' command.

Your avatar is a splitting image of you currently.
Don't bump a thread on the hour.....
So what you are trying to say is you never followed your OWN guide correctly?
Now I assume you did everything else and it is just the boot img problem.
So can you give some details on what it said when you tried to flash the boot?
-You extracted the img, placed it with your fastboot.exe and said fastboot flash boot boot.img
You can try the vol up and down and power to get your phone to reboot.

I flashed the boot.img in fastboot with the ''fastboot flash boot boot.img '' command while it should've been ''fastboot flash boot $pathToBootIMG\boot.img ''. My guide was wrong at that step.
That's the reason why I think the phone won't boot the rom, because it doesn't know where ''boot.img'' is.
That's why rebooting with vol up,down and power button won't do a thing. It just reboots,stays at the white htc screen..
I know how to resolve the problem, only I can't get into recovery so that I can fix it!

Reboot using the three buttons. When it is off, pull the battery out (it is a short window so be ready). Then wait a while, put it back in and hold volume down and press the power button.

You need to boot your phone into fastboot to flash the boot.img, keep searching on how to flash the boot.img, it is here, same as flashing recovery though.

Put the boot.img of your custom ROM (extract it from zip file) in the same folder where your adb tools are.
Then repeat that flashing step

Thank you i'm in recovery now. How should I flash boot.img?
Using the command ''fastboot flash boot $pathToBootIMG\boot.img '' i thought it would work gives me ''error: cannot load '$pathToBootIMG\boot.img'''

Why pull the battery? That is a completely unnecessary risk. Just reboot using the three buttons, wait till the screen goes blank, then wait for the lights at the bottom to go out, then immediately press volume down and power - it will go straight into the bootloader.
If you pull the battery just a fraction of a second too late you could get a current surge just as it is turning back on and that is a particularly dangerous time to pull the battery in my opinion.

For a very simple reason: people will see the instruction to pull the battery and they will pull the battery. A proportion of them will fry their eMMC chips as a result.
The post may be dead to you, but it still comes up on searches and people still read it. I've already seen it quoted in other threads.

[Q] Stuck after flashing boot.img

I'm on 2.20, was trying to get to CM10.1. Following instructions in this thread:
http://forum.xda-developers.com/showthread.php?t=1952076
Got to this point: "If you have the newer HBOOT 1.14 (you probably do if coming from stock 2.20), boot.img's will have to be flashed separately via fastboot. Extract the boot.img from you ROM zip of choice and put it in the same directory as fastboot. Reboot your device into boot loader and run "'fastboot flash boot boot.img' (no quotes)
You can then flash the ROM and gapps via recovery and reboot and enjoy."
I followed hasoon2000's advice that his all-in-one tool could flash boot.img for me. I grabbed boot.img from the cm zip, followed instructions to flash boot.img, all appeared good, however now I can't get to TWRP to flash CM. No matter what I do, when the phone boots to the screen with the red text, sits there for a while, and boot loops. The all-in-one tool can no longer detect any device connected to my computer. Any great advice out there or am I toast?

Turn on, hold power 10-15 seconds, until screen goes black, let off, press n hold volume down, press power just 2-3 seconds, let off power button but continue holding vol. Down
Remember to do a faxtory reset before flashing the zip

[Q] Reboots no recovery only fastboot

I have a one xl that will reboot after being on for 2 minutes
evita pvt ship s-on rl
hboot-1.14.0002
it is unlocked, but i cant relock it. Every time i try it says fails then reboots. I have also tried flashing twrp and cwm recovery via fastboot, but everytime i try to enter one it hangs on the teamwin screen. I have tried the ruu it reads my phone at first then when it says rebooting to bootloader the phone reboots normaly and get error 107.
Any help would be greatly appreciated.

What method are you using to try to relock the phone? What method are you using to install the mentioned recoveries? Please give as much detailed information as possible.
Sent from my Evita.

To relock i have used fastboot in cmd and typed fastboot oem lock. I have done that 10 times with the same result phone reboots normally and when i reboot back into bootloader it still says unlocked.
To flash recoveries i have used fastboot flash recovery ********.img
fastboot erase cache
fastboot reboot-bootloader
but instead of rebooting to the bootloader it boots normally

What did you do to the phone before all this started happening? Phones don't usually just start doing things like this of their own accord.
Sent from my Evita.

I bought it like this. The last owner said it happend after he installed a rom. I was hopping i could unbrick it with out jtagging it becuase i am still able to fastboot to it.

If you can't get an RUU to work I think jtag might be your only option.
Sent from my Evita.

I've only tried 2.20. I even extracted the system IMG from it but fast boot says it is too large. The only reason ruu won't work is because I can't get my phone to reboot into boot loader. Is there any way I can flash a different boot loader through fast boot.

Just curious, but when you type fastboot devices from the Bootloader, what is the output?
Are you running fastboot oem lock from the bootloader?

If when you type fastboot devices (while in the boot loader) in your computers command prompt, and it doesn't show your HTC device being attached, that means that your computer is not recognizing your phone. Have you installed the HTC drivers? Do you have the newest versions of fastboot and adb installed?

If you can connect to Google Play store, download recovery tools, if you have time. From there you could try to install a new recovery for your device. With only 2 minutes you will have to be quick though.

Alright, so I have a few ideas.
1. Try flashing a new rom via fastboot. (the following is based on the assumption that you have adb and fastboot in your path)
Flashing a ROM through Fastboot
So Why Do I Need To Do This?
You don't, normally you would flash a ROM through recovery, but why not have another way? Maybe your recovery partition on your phone is corrupt?
Maybe you just want to say "I learned something new!" whatever your reason here are the simple steps:
To start:
Quote:
Quote:
We need to download the ROM of choice to your computer. Once complete find the folder that rom is in and open terminal/cmd to that directory
(quickest way for windows; just hold shift and right click within that folder > open command window here) of course make sure your phone is plugged into computer and in fastboot mode.
Lets see how quick and easy this really is...
In the command line type:
Code:
fastboot devices
Seeing your serial number means we know all is good
Now lets type these commands:
Code:
fastboot erase system -w
fastboot erase boot
fastboot update superawesomerom.zip
Of course replace <superawesomerom.zip> with the correct file name
and last but not least:
Code:
fastboot reboot
2. Boot into Recovery via fastboot.
Plug phone into PC, connect with USB cable and have phone in fastboot mode, now open CMD/Terminal in the same directory as your recovery image
Code:
fastboot boot recovery.img
Of course name image correctly to fit command or vise versa
Now you are in recovery of choice within your device without it being flashed to your recovery partition. There is a time and a place for everything, can you think of ways this may help you? Sure you can!
This doesn't actually flash the recovery.img... it will just allow you to boot into it. Make sure that you have a good TWRP version.

Sounds like you flashed the 3030 version of TWRP. Download the 3020 version and put it in your fastboot folder. Plug in the USB to PC
Hold power and volume up untill the phone reboots. While it's still off immediately change to power and volume down and hold till it goes into fastboot (bootloader)
Now fastboot flash recovery TWRP.img
With the 3020 version.
Unplug the USB and hold power and volume up until it says the phone is booting.. let go and TWRP will load.
Go to Wipe / format data / type yes
Reboot to system and your all set

So I've tried that but the phone is still booting to recovery (flashing TWRP logo) no matter what.
Basically the phone is always on now because if hold the power button (or any other combination) for a few second it will just reboot back.
I have an access only to ADB, but I am not able to boot to bootloader at all, it seems the bootloader is damaged somehow.
Also that warning about unlocked OEM doesn't have that text saying "hold volume up to boot to recovery" etc. like before brick.

Hi there,
Try using the Huawei Multi Tool with the Unbrick option : https://forum.xda-developers.com/honor-8/development/tool-huawei-multi-tool-team-mt-t3523923
Speaking from experience, this little fellow helped me recover my phone when I bricked it ON DAY ONE after failed root attempt... (Derp)
Let me know if it helped you
(Leave a thanks if it did )
EDIT : This tool is also useful if you want to get lazy whilst rooting. I use it constantly when flashing diffrent bits and pieces

Clearly follow My steps To unbrick and get normal device ::
Step 1 ::
Download the full firmware of your device.
Step 2 :
make sure that your bootloader is in unlocking state
Follow the video blindly ::: https://youtu.be/OMKDnBqbi3U?list=PL...eT9J26lkefvVkK
don't panic of mobile.
Step 3 :: done ..enjoy u did it
--------------------------------------------------------------------------
If you bricked on nougat then follow the below steps
step one :::
download the downgrade package to mm .
then extract the zip and open the update.app using HuaweiUpdateextrator in that select recovery and extract
1.now, boot your device into fastboot and flash the recovery (Optional)(try this if it said incompatible version on recovery)
2. on your sd card and make a folder "dload" . and copy the update.app which we have extracted earlier
3.the switch off the device and press all three buttons you will be reboot into recovery and done . you device will be okey

Booting to the bootloader is just a timing issue
Phone must be hooked to PC with USB
And volume up and power till it goes black
Then immediately volume down and power and Hold untill the bootloader loads
Keep trying until you get it

I've tried that, but I am still stuck as that tool is using fastboot as every other tool to flash .img files.
Thank you for the tip though.

Plug phone into computer with USB, then hold down power + volume down until it eventually boots into bootloader. I had the same scenario as you and that's how I got into the bootloader. You can flash either a good TWRP or the stock recovery, either one will work.
