[Q] Permanent problem with Unlocking Bootloader Nexus S - Nexus S General

Hi guys,
I searched forums, web with no positive results. So I start a new thread. Here is the situation: one day my Nexus S (Worldwide edition) froze on restarting with the Google Logo on the screen. Every time I try to turn the phone on it stacks at Google logo. When in the fastboot mode the status is Locked. Every time I try fastboot oem unlock I get Phone’s prompt with Yes or Not to unlock bootloader and after choosing Yes, the status doesn’t change to Unlock. Tried on Linux, Mac, Windows (drivers installed successfully), the same result. Tried to force Flash Stock + Unroot in Wugfresh, doesn’t work due to the Locked Bootloader.
typing "adb devices" in cmd (should return the device number) shows:
List of devices attached
......
Empty line above
Any word of advise how to force Unlocking the Bootloader would be greatly appreciated. Please help. Thank you!

It looks like your device is not recognized in Fastboot mode...
Have you turned on USB Debugging while connecting PC and Allow in Device when Prompt some message ..
Go to fastboot mode and write this command... fastboot devices
If it will give you a message like this
List of devices
1235456785164
Then your devices is successfully recognized...:good:

It is not recognized by adb devices, but:
fastboot devices - gives the following output:

Pretty sure you have a bad USB cable, the error means the fastboot binaries are working on PC but can not connect to device, often this is due to a bad USB cable or port
Try a new cable, one you can verify works transferring data

Thanks, I tried 3 different cables on 3 different operating systems, with the same problem unlocking the fastboot. When I send fastboot oem unlock the device opens a prompt with Yes or No choice, but after choosing Yes, it stays Locked

Something indeed is strange...
So fastboot is for bootloader and adb is for within os and in recovery.
Try booting into recovery and see if adb works, also boot normal into your bootloop and see if adb works there too

Loading into basic recovery and trying to wipe data/factory reset - doesn't work. adb devices returns the following output:
./adb-linux devices
* daemon not running. starting it now *
* daemon started successfully *
List of devices attached
****empty line here****
Somehow, adb doesn't recognize the device, whereas fastboot devices shows it.
Is there a way to flash new bootmode with the currently locked bootloader?
Thank you!

Hope this Guide will help..

UPDATE (resolved)
Here is an update. Hope this would help others with similar issue, as I've read many threads and folks complaining that they weren't able to unlock fastboot and further root their Nexus S, and who can't boot the phone, which stacked with Google Logo (soft loop). This was the case with my device and finally I got it resolved. I've read some guy tried to hit the phone and after that he was able to boot phone normally. It related to some hardware electrical circle issue. Anyways, I tried to hit my phone by placing it under the direct sun in balcony for some time until the phone got hot and then power it on. And ooops, my phone started booting passed by that Google Logo which was the good sign. Once the phone booted up, I went ahead and activated USB debugging and restarted the phone into the Fastboot mode. while the phone was still hot and in Fastboot mode I run "fastboot oem unlock" and hey, fastboot is Unlocked! Again, this was done while the phone was hot, any previous attempts (read above) weren't successful. From that point, I went ahead and rooted my Nexus S by Nexus Root Toolkit, available on wugfresh.com/nrt, without a slightest problem. Now my phone is fully rooted, bootable and working fine. I thank all who replied to my thread and tried to help and hope this info would help someone with the similar issue.

I am thinking once i get them i should be able to run using FAstboot commands
without even unlocking(as fast boot oem unlock also not working for me) boot loader..somebody please confirm...
I tried fastboot update update.zip with Official 2.3.3 ROM but i get following error

error: update package has no android-info.txt or android-product.txt
My phone is not rooted neither the boot loader is unlocked( I have failed to unlock it with Fastboot OEM unlock)
First thing first... connect your phone and type "adb devices". Does your serial nr show up? Turn off your phone and boot into bootloader (hold vol up + power). Type "fastboot devices", does your serial nr show up? If not, adb and/or fastboot isn't recognizing your connection and device. If it does, you SHOULD be able to type "fastboot oem unlock" to unlock your bootloader.
Tip: you can view your bootlooader state on the device display when inside the loader. It says "State: LOCKED" or "State: UNLOCKED" respectively.

This will work for the t? I was under the impression we didnt have any images for the 9020t version.
Edit: I just signed up for the site and everything, and it says nothing about being for the T version.
Yes that Odin package from Samfirmwares is for the I9020T. However it is not version 2.3.3, but rather 2.3.1 GRH78.

Nexus 7 Bootloader Locked!

After Android tried to update itself to the newest version, it seemed that this failed and has caused a "boot failed" message. The tablet refuses to go into recovery mode, its marked as red. The only accessible mode is going into bootloader. After reading many forums and trying my luck with toolkits of all sorts (Nexus 7 Root Toolkit, Nexus Root Toolkit, Android SDK commands), the bootloader refuses to unlock. I have successfully installed the usb drivers since my pc recognizes the device. fastboot devices recognizes the devise but adb devices doesn't. The bootloader is locked and nothing else is accessible, whats worse is that through all of these toolkits and commands bootloader refuses to unlock, trying to unlock it always results in a failure message (unknown error). Commands such as format, unlock or erase fail in reviving the system. Anyone have any experience with this? I have searched for over a week now and im terribly frustrated by this. :silly:

do it the right way, dont use toolkits.
to unlock the bootloader, go into the bootloader(fastboot), connect the divice via usb, type..
fastboot devices(to make sure your device is visable)
fastboot oem unlock(to unlock the bootloader)
if you get an error, reboot the bootloader and try again. i had an error the first time on my replacement seven, second time it unlocked.

Thanks for the reply, i tried this several times, each time rebooting bootloader, but the command still posts an error in unlocking the bootloader. Recovery and Restart bootloader are marked in red font, Start is in Green, Power off White. I also tried flashing the recovery, since its inaccessible but because of bootloader being locked in won't allow me. :S Anything else you know that can be done ?
Reflash the bootloader?
edit: making VERY sure that you DON'T erase the existing bootloader first.
Try a manual update

You can try a manual update. Download the update and run adb sideload. That was not working for me, cause my Nexus it's allready updated, but hopefully it will work for you.

fortunatley though bootloader doesn't allow any command even the erase, it wouldn't allow me, nor formatting it as well. So i think the bootloader is intact. This is the screen i get from pressing Power and Vol Down.

As i have come to learn, adb can only function when debugging is enabled, in my device it wasn't unabled. Also the recovery program cannot be opened so sideloading through commands cannot be done. At least according to how some forums described the How To sideload through adb

try one more time with a different port/pc if it daesn't work it may be a hardware fault, i think a corrupted sd.

Use the volume up/down keys to navigate to "Recovery mode", then press the power button.
When the Android with the red exclamation point appears, hold down power first, followed quickly by volume down and volume up. (So that to start, you're holding down power, then you're holding down all three). After 2-3 seconds, release all three keys.
Use the volume up/down keys to select "apply update from ADB," then press power to select it.
On your computer, open up a command prompt or terminal window.
Using the command line, navigate to the folder containing the ADB executables and the update file.
type:
adb.exe sideload <update filename>
On my Nexus with Jelly 4.2 usb debugging is not enabled too, but I still get the option in recovery mode menu. Operation not succesful cause I cannot upgrade from 4.2 to 4.2. I will wait for another update and then try it again. Good luck!

recovery mode cannot be opened, the text font is red on the tablet and clicking it does nothing. :S
Also tried to completley flash the device but unable to. Going back and doing an fastboot oem unlock yields the same feedback.
Unlock Bootloader on 4.2
Hello, I was wondering if the bootloader in 4.2 can be unlocked the same way as it was on 4.1.2? I recently got a new nexus 7 and updated to 4.2.
Thanks and Cheers!
After some research into my issue, i have discovered that other users have posted "unbricking" solutions through a program called nvflash, when the device is put in APX mode. But unfortunatley i've yet to find a nvflash solution for nexus 7. I will experiment with the commands and what the others have reported as a solution.

Fastboot discussion.

I have searched and couldn't find a fastboot thread. So here it is.
I found out fastboot is working on Linux.
Bad news is Windows seems to need another driver for fastboot.
Please help look for a windows driver or make one.
The fastboot commands all seem to work fine.
Here you guys go! Enjoy.
Code:
[SIZE=5][SIZE=3][SIZE=5][SIZE=3]adb reboot-bootloader
fastboot -i 0x1949 command_here[/SIZE][/SIZE][/SIZE][/SIZE]
Just noticed pokey9000 said this but it was overlooked.
pokey9000 said:
That's it. And you're running fastboot as "fastboot -i 0x1949 your_command_here", and you have udev set to allow permissions for that VID (or are running as root) in Linux?

Thank you.
Still don't believe me, look at the last picture.
I'm having issues with some commands. Please test it out and enjoy!

In the Fire TV section a fastboot cable was created by splicing two USB A to B cables together, so that the A to A ends were together which when connected from your computer to the Fire TV on bootup put the device in fastboot mode, in the process then your computer recognized (Running Windows 8 was the example given) the device and installed the proper drivers. Since the devices are similar, a potential solution would be use the cable, have the computer recognize it and install the drivers, then backup the drivers, and share them here for others to use.
Click to expand...

I'm quite sure the cable isn't the issue. Also that's just it, I can't get windows to recognize it or find much info about it. The adb driver for the device isn't enough I guess. The funny thing is windows says it's working properly as 'Kindle' for a little while when you plug it in (while in bootloader) then device manager refreshes and reports 'cannot start'. I tried launching 'fastboot devices' many times but still nothing. I think it needs a software fix and not a hardware one but I have no past experience using fastboot. So... noob alert.
btw the driver windows tries to use is ms_comp_mtp(Generic driver installed=true) and adb uses the Amazon one on the fourm here.

I have a problem
I don't think there's ever been a question of getting into fastboot mode by using the adb reboot-bootloader command.
The issue is how to enter fastboot if the device is semi-bricked.
The device has source in the original bootloader to boot into fastboot mode if both volume buttons are pressed while powering on the device. But this has since been altered and now will only work if the device is unlocked.

Is flashing the stock .bin file any different than doing a factory reset?
I am bricked, have root, have adb, can get fastboot using adb reboot-bootloader in windows 8. I also have a Linux box if necessary.

Fastboot works with win8? Not with win7.1 If you have fastboot working with win8 please go to device manager (when your in the bootloader) click properties on the device then look for what driver it uses.

My main reason is to get fastboot working with windows. I just can't. Linux seems to work with fastboot but I can't access it via windows.
Just uninstall the kindle driver and replace it with the generic fastboot one
hello all,
i've kindle fire hdx 7" , no adb, grey screen logo then shutdown and goes to black screen.
when connected using cable, it show new devices... QHSUSB_BULK and sometime unknown devices.
press hold power button and volume up only go to recovery mode, but cannot recovery the system..
always go to grey screen logo...
sorry for my bad english language...
hope all of you, understand what i mean here
i need solution for fix the problem soon. thanks
I think all that works is reboot into fastboot mode. Windows 8 says no drivers are loaded. I tried a command (can't remember what) and it just went out to lunch so... I guess windows 8 isn't working either. Only to put the device in fastboot.
there are three oem commands:
oem device-info
oem idme
oem relock
Click to expand...
Click to collapse
but it doesn't support oem unlock so there must be another way of unlocking the bootloader, when you try some of the commands the device returns "not allowed for locked hw". Does anyone know what the "hw" is ?
hw = hardware?

Read up on this bud.
Hi,
I have a bricked kindle hdx 8.9 that stops at "Kindle Fire" boot screen. I am a newbie at these things.
Just discovered that it still respond to some adb queries. Sounds like there is still hope to recover... Could it be the bootloader is messed up? Anyway to reload an image boot file to repair?
Also "fastboot reboot-bootloader" puts it into fastboot mode...with the status "ready"....and i just dont know how to proceed. Any one can help?
uhg
Facepalm
just back a little: was rooted in April but with subsequent amazon auto updates - didn't have su status. But I was able to load apps & files, installed vpns, quite a few docs,mp4 files, etc. Not really using much of the new freedom or whatever was left of it... Nothing exciting.
Was working well until one fine sunday afternoon, just 2 weeks ago when it just simply stopped after rebooting from a previous low battery charge. Was told it could be an interrupted routine update when the battery power just fell below threshold - but thot it wouldn't have erase the previous image before the new update is effective. Or it could possibly be a deleted file that is related to the booting process as I did a bit of clean up prior to the last reboot?
In the meantime, I did some adb shell/pull to explore or extract the files, photos,etc in /sdcard & other places back to my PC just in case they were not backup by the cloud. Maybe it was not bricked...but just lost a boot file or something...
In a bad situation, have absolutely zero ADB access as my build.prop is botched (bad permissions) and I did a factory reset in hopes of recovering. There is a "fastboot cable" on amazon that says it will reboot a hdx into fastboot mode, but I'm unsure of it's legitimacy. Help?
here try

I don't quite understand. Why is a special cable required for this? What makes it any different from the standard one that comes with the device?
I don't know if this will add anything to the discussion...but I can confirm fastboot is working on Ubuntu 14.04. I am using a kindle fire HDX 7" and it detects it on devices..and most commands work. Sometimes the terminal must be closed and reopened for commands to go through..
fastboot oem unlock works..or rather it says "Okay" but I'm unable to flash anything.

Bootloader is ok but no command works

Hi
sorry if post is duplicated , i search but not found on this topic
When i connect my mobile to pc and then run command to go to bootloader ,
it shows Daemon not running. Starting it now on port 5037
then goes to bootloader
in bootloader no command work there , means only adb reboot bootloader works
even fastboot devices shows nothing
please advise me what i have to do
Sorry for my bad English
Thanks
if from your pc you type:
adb reboot bootloader
does it go to the bootloader?
If so, while the bootloader is displayed, from the pc if you type:
fastboot devices
Are you saying it responds with nothing?

So I'm confused.
If I type "adb reboot bootloader" with my phone connected; it boots into fast boot mode and will accept fastboot commands.
it shows the "Fastboot" screen with the option to start the device if the power buttoned is pressed.
What are you trying to do?
Are you saying you don't get the screen?

What drivers are you using.
I presume you are on a Windows laptop?
yes on windows 10
Sent from my PH-1 using XDA Free mobile app
Sounds like you're using an older fastboot, so you'll need to do fastboot -i 0x2e17 <whatever_command>
Or you can get the latest platform tools from https://developer.android.com/studio/releases/platform-tools#downloads
Did you install the essential phone drivers?
not sure about version but download some days back from links provided.. any ways thanks download from ur link then let u know
thanks

Moto G5 Plus "bricked" after update.

Hello! I don't know if there might a be a solution for this problem, we've tried many stuff that's been posted here on the forums but ended up in the same results, so no luck. My friend's Moto G5 Plus "bricked" itself while updating to Oreo some time ago, wasn't rooted or anything, bootloader wasn't unlocked either. We can access the recovery menu with "power + vol+", but any option we try to use ends up with the message "Failed to pass validation, backup to fastboot". Some of the solutions I've tried require the bootloader to be unlocked, but I haven't been able to unlock it since my friend never checked the "Allow OEM unlock" option. He took the phone to the official service but they said they couldn't do anything and wanted to sell him a new phone. Any help is appreciated. Thanks in advance!

Would be helpful to know what exactly you've done to rescue that device.
For example, did you try to wipe the complete device and fastboot flash the latest signed Oreo firmware?
Is the device recognised by a PC?
What about using Lenovo Motorola Smart Assistant?

Hey! From what he told me, at first he was able to access the recovery menu, when then little Android with the red mark shows up, then he used the Smart Assistant and after that he gets the validation error message that I mentioned. I suppose the Smart Assistant made things worse? The device was initially recognised by the PC, but now it isn't. We tried to flash the stock firmware and unlock the bootloader but we didn't have any luck either. Since the PC didn't recognized it anymore we tried a few things to make it work but ended up giving up.

So you can't get to the screen with the dead android (fastboot mode) or recovery with the key combination (power and vol down/power and vol up)? You should be able to get there and check the connection by typing
fastboot devices
or
adb devices
Is the battery full enough to start?
Do you see the device in Windows devices manager?
PC should recognise it at very worst, as qhsusb_bulk. Your PC must be in test mode, and then when you connect look in device manager, under usb devices, and a hard bricked phone will show as qhsusb_bulk. Anything else, you should be able to communicate with ADB/fastboot, as Wolfcity stated. If it does show as qhsusb_bulk, you will need to use vaches' blankflash to recover the unit.

I tried to attach a couple of screenshots but I get the "bad request" message here. Anyways, when we do a normal boot we get the validation error message and we are sent directly to fastboot menu, but there we cannot choose any options because all of them lead to the error message again.
It's been a couple of weeks now but the last time we tried doing something, the device wasn't showing up in device administrator nor being recognized by adb.
As regards to the battery, we've left it charge up for some hours, so I guess that's not a problem, although we cannot see the percentage.

I'll tell him to check if it shows up as qhsusb_bulk and update here. Could you explain a bit more or link to a thread about vache's blankflash? What is it exactly?

This thread is long, but alot of good info on hard bricked Moto G5 plus devices.
Code:
https://forum.xda-developers.com/g5-plus/help/moto-g5-plus-hard-bricked-recognized-t3636457
To get PC in test mode
Code:
Here is how to turn on or off the Test Mode feature in Windows 10.
IMPORTANT: Please remember that turning off the Test Mode feature may force the program/driver which is not digitally signed stop working.
Step 1: Open Command Prompt as administrator. To do so, type CMD in Start menu search to see Command Prompt in the search result. Right-click on Command Prompt entry and then click Run as administrator option. Click Yes button when you see the User Account Control screen.
Step 2: At the Command Prompt window, execute the following commands:
To enable the Test Mode:
Bcdedit.exe -set TESTSIGNING ON
To disable the Test Mode:
Bcdedit.exe -set TESTSIGNING OFF
If the above command didn’t work, this one must work:
Bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS
Bcdedit.exe -set TESTSIGNING OFF
You may exit the Command Prompt now.

Update: The PC detects the phone as Android Device > Mot Composite ADB Interface.
But once in adb, adb devices isn't working. It doesn't recognize the device.

It is recognizing the device, " Mot Composite ADB Interface" is correct.How about
Code:
fastboot devices
? It should show the device #. ADB doesn't always show devices.

Yes! Fastboot devices shows the device! So now we have to procede with the flashblank.zip and all that from the other post right? Also sorry for the late reply, I've been pretty busy these past days so I left him with all the work.
