Hello:
I sent my NEXUS in to SAMSUNG for a touch screen non-responsive on the left side issue. The tech stated there were no problems with my NEXUS S!
Upon turning it on, there is a padlock on the botton of the Google splash screen.
I called Samsung and the "level 3" tech said that my phone was now locked to T-mobile. I though that was BS.
Anyway what is it and, can I get it back to normal? My wife has the same phone and here does not have any problems so far.
I've attached a pic of the screen that shows the padlock. Thanks for the help.

that means your phone is unlocked as far as I know. I did my first unlocking and rooting of my nexus last night. When I went through the unlocking process, the "unlocked padlock" started to appear on my startup. If you hold "volume up" and the power button and turn the phone on. it should say unlocked on the fastboot screen...
You have unlocked the bootloader my young Jedi.

yup, unlocked bootloader.
thats not a bad thing, its a wonderful thing!
lol you rooted your phone and unlocked the bootloader. that is what that lock symbol means. did you forget, or not do this on purpose?
Thanks to all that replied!! I kinda figured that is what it was.. Like I said I didn't do it, the Samsung repair facility in Texas unlocked it. I called the Nexus S support line and the Level 3 tech said " When we reflashed your software, it locks your phone into the T-mobile network" and that was after she went down the hall and consulted with the "developers", Samsung tech support is a Joke. One day I'm gunna root this thing!
Thanks Again Guys.
And to the XDA moderator, sorry I posted in wrong section initially, rookie mistake..
Anybody know how to remove this lock symbol? How to re-lock the bootloader again?

several ideas, what error did it show? what is shown in device manager when you plug your phone in the pc in bootloader?
edit: how did you unlock it?!
Try this, these guys do a great job if breaking things down.

When I go type in 'fastboot devices' or 'Adb devices' it says
"list of devices attached:" and nothing underneath it .....
I have tried updating drivers via PDAnet .... still nothing.
the drivers I have are 'ADB interface'.
Am I missing drivers specific for bootloader or something??
Basically, the phone wouldnt restore or factory reset, so I decided to root it? so I found a new '1 click root and recovery'.
Once I run the script, it unlocked bootloader and also reset my phone which worked great. Only thing I want to do now is remove the open padlock icon on the google screen (which I think is by re-locking bootloader) but when I put in the typical 'fastboot oem lock' nothing happens .....
Much appreciate the help, thanks.
You got to remove everything "custom" (cwm recovery, user roms etc) from the device before you can lock the bootloader again.
When you are trying to lock your bootloader it doesn't do anything because your device isn't correctly recognized by windows, this is prolly due to missing/wrong drivers (try uninstalling old ones and then follow the unlockr guide to rooting your phone/installing adb, http://theunlockr.com/2009/10/06/how-to-set-up-adb-usb-drivers-for-android-devices/).

are you positive sure that i can't lock my bootloader with customs kernels, roms or recoveries? i don't think that's entirely true!

what is your phone 4g or gsm?!
Hi, I have a friend who has just smashed their Desire S whilst out on Sat.
Unfortunately, as the title says, they have no screen (touch doesnt appear to work either but no real way of telling!), not root, no USB debug and I have already checked and they didnt have their contacts set to sync with their google account but with the phone! :-/
Can anyone give any suggestions other than a screen replacement? They have already got an S3 on the way today so just want to be able to restore their contacts.
Cheers and thanks in advance!
I think this is definitely possible, but it may get very complicated.
Do you have adb in recovery (you'll have to boot into fastboot and blindly navigate to the recovery option)? Is the bootloader unlocked?

Thanks for replying Aquous!
I have just been given the phone today from a friend to try and help them out so im not sure on either? Do you have a desire s and would be able to tell me the button sequence to get into recovery to find out? As for the bootloader being unlocked, i very much doubt it as the phone was running a stock orange rom.
Any ideas?
Cheers,
It is unlikely indeed that you will be able to recover the data as the phone is. If you're in the UK (possible as the phone is on Orange) and fancy posting it then I can stick my LCD and touch panel on it for you so I can recover the data.
Also if u r in the uk, try a phone repair shop that has jtag, they should be able to pull any data off the phone.

Then you probably don't have adb in recovery either.
We can try the easy way first: from the Google Play website (on your computer), download TalkBack to your phone and see if you can launch it blind. From there on, your phone will read to you what's on the screen
If you can't manage to do that, I have another option in mind but it's complicated and you may not be able to recover your contacts:
Unlock the bootloader via htcdev. This will wipe your data, but if you don't allow the rom to boot after the unlocking, this is OK.
Immediately after issuing the fastboot oem unlock command, HOLD DOWN THAT VOLUME - BUTTON. If the ROM is allowed to load, your data will be significantly harder, if not impossible, to recover.
If you held Vol - correctly after the unlock, you'll be in fastboot (if the phone vibrated, quickly pull the battery before the rom starts writing to the data partition).
From fastboot, boot a custom recovery ('fastboot boot recovery.img')
In this custom recovery, you have adb. Pull the data partition and run file recovery software to try to reconstruct the data that was on it but was wiped by the unlock process.
Purposefully not giving any clearer instructions than this, because if you don't know what you're doing the chances are very high that you're going to do it wrong and won't be able to recover the data.

Holy ****, you actually did this? And it WORKED? You, sir, have some serious balls! Gratz!
By the way, this has HUGE privacy implications

Yup, everything i needed off it worked.
I left it for a while as a last resort because of the risk of total data loss and bought a replacement screen which was DOA!
So you plan came into play and it really worked. It wasnt so hard as the steps you gave just helped me get the order right in my head rather than trying something and mucking it up even more!
Thanks again good sir! She was very pleased!
I have a HTC One MIni that is stock in a fastboot loop every time I turn it on. I can't get any option from bootloader to work. So after doing some reading here I was going to unlock the phone and try to fix it but I can't unlock the phone. So fastboot was able to get the code and I went to htdev and get the unlock.bin file and I can run it with fastboot and it says it is all good but the disclaimer that it is supposed to come up after this on the phone, never comes up. I thought maybe restarting it would show it is unlocked but no luck. So I'm stuck with the phone only booting on fastboot mode and not being able to unlock it and therefore can't install anything to fix it. Is there a way I can fix it?
Thank you
So, I've unlocked the bootloader, flashed TWRP. It says it's successful. But when I try to boot to the recovery, I get a warning that says "Your device software can't be checked for corruption. Please lock the bootloader." and won't load TWRP after that.
I've checked a bunch of other threads, but can't seem to find a resolution for this. Can anybody help?
Tap the power button twice when the screen appears. (If it's the screen I think it is... American carriers are known to add extra protection)
That just puts me right back at the bootloader. It does say S-On though. Do I need S-Off?
Goodnight all,
I unlocked the OEM bootloader and Rooted my Samsung Galaxy Z Flip 4 using Magisk. It is a European model.
Now each time I start it I get warning messages that the security has changed as a result.
I reset my phone completely and I still have these warning messages on startup.
Is it possible to remove these warning messages because I will most certainly resell the phone???Is there a solution to lock the OEM bootloader again or is it irreversible???
Thank you in advance for your help and good evening to all.
This is by design. An unlocked bootloader should display the ORANGE state on boot to notify the user. This is normal, and no action is needed.
It is not possible to remove these warning messages as this is a result of the bootloader functioning as intended.
You can re-lock your bootloader if you want but make sure you have performed a clean flash with the factory firmware first. You would then follow the same process you used to unlock the bootloader (device off, hold both Volume buttons, plug in USB cable).
It's just a minor inconvenience though and does not affect device operation.
Good evening,
@V0latyle
if I understood your explanation , I download the latest firmware which is installed on my phone with the help of SamFirm or other software.
Then I use Odin in administrator mode and I select the file in the BL box, the file in the AP box, the file in the CP box and especially in the CSC box I put the CSC file (and not Home_CSC) in order to a hard reset of my Samsung Galaxy Z Flip 4 phone. Once the flash is done, the phone reboots to factory state, I click the build number 7 times then I go to developer options and there I could finally lock my OEM development loader again??? Once I've done all of this
,will the bootloader security warning message go away???
Please tell me if I understood correctly please and above all thank you again for your help.

You don't have to do anything with Developer Options or the OEM Unlock toggle. OEM Unlocking only functions as a "safety" to permit you to unlock your bootloader.
If it is already unlocked, simply follow the instructions you used to unlock it after you enabled OEM Unlocking the first time - with the device powered off, use the key combo to boot into Download Mode, then hold Volume Up until you see the device lock warning. When you relock the bootloader, it will wipe data. Once done, no further steps are needed.
If you want to tinker with your device and enjoy the benefits of root, why not leave it unlocked? Sure the bootloader warnning is slightly annoying but again that's by design.
@V0latyle
ah ok, I understand better, I'm doing the reverse step of what I did the very first time I unlocked the OEM bootloader.
I put my phone in download mode by connecting it to my computer and then I hold the volume up key for a long time to lock the OEM bootloader. And if I understood correctly, once this is done, my phone will be factory reset and no more warning message on startup. That's right ???
In fact, I'm asking you all this because I want to sell my phone to switch to the S23 Ultra.
thank you for your help and your feedback

Yes, if the bootloader is locked and the firmware is original OEM, there should be no warning.
@V0latyle I'm testing all this to the letter tomorrow evening and in the process I'll come back for other people that it could help.
thank you for your help and keep you posted
Hello,
I did what you said and problem solved, the warning messages at startup disappeared.
Thank you again for your help @V0latyle
But u know that KNOX is triggered and u loose some of functions anyway even if you relock bootloader ?
