Samsung i780 cannot remove the PIN lock!

Hi all,
One of the users in our company has locked himself out of his i780 by forgetting the 4-digit PIN he set on the device (not the SIM PIN).
The problem I have is that it is running one of the older ROM's that did not have the hard reset button combination on it so I cannot reset it at all. It also won't enter bootloader mode using the usual combination (although this may be because of the countdown timer on the device not accepting input).
Anyone got any ideas on what I can do next?
Thanks.

I wonder if you can short certain pins on the flash chip to destroy the checksum and thus cause the device to reset itself - this method was used in the LinkSys WRT54G router and some MP3 players..

did you try reflashing the phone with new firmware? might help since the pin is set on operating system level (afaik), the firmware upgrade is done on bootloader level.

But he can't get into the loader mode, so Mirage is a no-go.. I suppose the phone doesent even connect to ActiveSync, hm? If it would then the official HL1/2 updaters are able to reset the phone into the loader mode and flash it

Correct, I cannot get it into bootloader mode because the usual key combo does not work and activesync refuses to recognise the phone until the PIN is entered so I cannot use Mirage or the official updaters!
Looks like I'll have to send it off to Samsung!
Cheers guys.

try contacting them first by phone and see if they can't help out. otherwise you'll have to wait for a looong time

Yeah, I've sent phones to them before, they do take a while.
They say they need them back to take the lock off so looks like it'll take a while!
Moral of this story: Don't forget that damn PIN!

Doesn't it wipe itself after the 50th attempt?
How old is that version? before Nov2007? Can you post the version number? something like "i780XXHA4"

By Omnia this ok
1. type *7465625*638*# to set
2. type your MCC/MNC code (list here: http://en.wikipedia.org/wiki/Mobile_Network_Code), e.g.26003 for Polish ORANGE
3. type your new NCK (12345678), then OK
3. type *#7465625 to check your lock
4. type #7465625*638*# and type your NCK (12345678)
5. enjoy.

Lock Screen: x/10 Attempts Remaining

My G4 gives me warning about unlock attempts remaining when using a pattern or knock code (See attached image).
However, it doesn't say that it's going to wipe my device.... so I'm not sure what it's going to do if all the attempts are used. I don't want some idiot to pick up my phone and be able to wipe the device just by messing around with the unlock screen.
Can anyone confirm what happens when all the unlock attempts are used?
Is there any way to disable the unlock attempts limit `feature`?

Why on Earth would you think it wipes the device? It, like most any other phone, has a longer wait period to unlock the device if you incorrectly enter codes in.

On page 41 of the Verizon LG G4 Manual it states:
After 5 unsuccessful attempts to unlock your phone, you're prompted to enter a text phrase to confirm that you're trying to unlock your phone.
You have 10 opportunities to enter your unlock sequence. After 10 unsuccessful attempts, your phone will automatically perform a factory data reset and all of your
personal files will be erased. You will be warned after the 9th unsuccessful attempt.
If you've set a Knock Code, after 6 unsuccessful attempts, you're prompted to enter your Backup PIN to unlock your phone.

That has a lawsuit waiting to happen. Thanks Verizon... (or LG, if this is a phone design rather than carrier)

My Mom's Galaxy S5 for Verizon wipes the phone after 10 unlock attempts by default but has an option to turn it off (she discovered this the hard way when she wiped her phone because she couldn't remember her pattern).
Also, I know that the HTC One M8 does this.
Thankyou woozzy101 for finding that information, its very helpful. Now I just need to find a way to disable this idiotic 'feature'.
I just tested using an invalid Knock Code 5x times to make it use the backup pin... However when entering the backup pin it doesn't tell me that there are 'x attempts remaining' , but I only attempted to enter my backup pin once (and did it correctly) as I'm afraid of wiping my device by testing entering invalid backup pins. Is anyone brave/crazy enough to test what happens if you use all of your invalid knock code attempts then enter the backup pin incorrectly multiple times? I want to know if this will result in wiping the device... if it doesn't then I'll be using this unlock method instead of the pattern.
Also, does anyone know if this 'feature' is something that is part of Android, or a custom addition by LG or Verizon?

I downloaded the G4 manual from Verizon to familiarize myself with the phone before I got it. When I read about the factory reset I was like, ruh-roh, that is an accident waiting to happen. Way too easy to wipe someones phone messing around with it. Or if you have kids and your kid gets it and plays around with it....
I keep re-reading the Manual and the factory reset falls under "Changing Your Screen Lock". It might only do factory reset if you already have the phone unlocked and in the settings to remove the lock screen? Best Buy wont deliver my phone till June 5th (this Friday) so i cant really test it

On my EU origin H815 at the 10th attempt for a pin it simply tells me to wait 30 seconds just like it did at 5 attempts. At 15 attempts you get this;

After the 20th you get this;

Unlocking Motorola ----- Moto G5 TD-LTE EMEA 16GB XT1675

Hi there
I need some help please....?
I have a Moto XT1675 mobile phone.
The issue is that when i start the phone up its asking for a password. I dont have the password and I am not sure what I can do to reset the whole phone so that i can use it again.
Does anyone have a solution to this issue ????
Thank you

Boot to recovery and do a factory reset. Unless u have a SIM lock password; that should do the needful. If it's a sum lock remove the SIM and try

Galaxy S9 Developer options problem

Hey Forum! Hopefully y'all can help me. I have a S9 from Rent A Center and so does my wife, well her phone updated to Pie(9.0) 3 weeks ago and we're both on Cricket Wireless. Well mine hasn't updated and I've even went in and manually checking for updates and it says my phone is up to date so I downloaded the firmware from Sammobile and it failed cause i forgot to turn on USB Debugging in the developer options. So I restart my phone and go to settings and hit the build number and it says that developer options has already been turned on. But back in settings the options are nowhere to be found. So I figured doing a factory reset would help, but when i reset the phone and booted it up and went back to the build number and pressed it 7 times instead of saying developer options had been enabled it backed completely back out to my home screen and so i went back to settings and hit the build number again and it said that the developer options had already been turned on but again nowhere to be seen. So my question is is there a way to remove RAC from the phone or is there a way to remove knox where rac is on the phone? I need help cause I want the update, but it seems there is no way to do it with RAC on the phone.

USB debugging has nothing to do with flashing firmware with Odin

Ok then. I get a mdm mode cant download when I try flashing the firmware in download mode

Not sure if it still works with the S9, but there was a trick where you set up PIN security on the phone, but also enable the setting where if the wrong PIN is entered 10 times it factory resets the device, this supposedly removed the Rent-a-Centre crap after the reset which you cannot do while it is still active
Then enter the PIN 10 times wrongly

So it's a different factory than going into the settings and doing a factory reset?

No, same one but supposedly you do not have access to that with Rent a Centre software on the device, nor can you do it from recovery (As far as I am aware from reading others with the same phones)

Oh so basically I'm screwed until they come out with the update for my device

Do you have the ability to factory reset your phone as it stands right now?
If no, follow the above instructions...

Yes I can and have reset my phone. But when I set it back up it shows up rent a center in the Knox portion of it and I guess reinstalls them. So to speak

Remove VMware Hub bloatware

Good morning,
I'm writing this post 'cause I'd like to know if it's a possibility to "unlock", if I can say this, my phone. My company installs on my phone VMware Hub and the Debug USB is locked because I cannot unlock the related menu. I've tried to format the phone from original recovery by wiping data and nothing changed. So, I've run my phone into bootloader in order to overwrite the original firmware with a new original one. The process is ok but when I restart my phone, VMware is installed and configured.
Now, a question, is it possible to remove it withouth root or debug USB? I'm so annoyed because it is possible to check everything I do in my phone

Did someone answer you? I have the same problem.
Thanks.

Hello, sorry for such late reply been way for too long, the answer is simple, go to developer options, select the oem unlock option reboot the phone to download or recovery i don't remember, a message will come before that will alow you to unlock bootloader, precede to unlock, i can't recall if the phoene will reset but i assume so, when it comes back it will no longer be tied to your employer, it will be an A50 like any other bougt on the store, keep in mind that from then foword you will get a message saying that bootloader is unlocked at phone power on, that's it
