[HELP] Forgot Knock Code Backup Pin - G4 Q&A, Help & Troubleshooting

My phone had a knock code on it that was working just fine. Some one accidentally pressed in the wrong knock code a bunch of times and the phone now asks me for the backup pin that I had set up when I first set up the knock code. Unfortunately I have forgotten the back up pin but I do remember my knock code. I have tried figuring stuff out about it and a lot of posts were talking about factory resetting the phone. Is there a way to avoid that?
I have some data on my phone that is important to me which has not been backed up.
I do not have Android Device manager set up on my phone
in such a situation is there a way out?
I need suggestions please.

When you have not an encrypted device there are several ways e.g. use SALT to backup your userdata partition . When it is unlocked and you have TWRP you can just remove the code..

Yeah this is where I've messed up, I had been using my phone's default encryption feature (but i have the key).
I have not installed TWRP on my phone and have not enabled the boot loader. Will SALT still be able to backup my phone?
What should I do?

FIX:
Hi guys,
Sorry for your screenloop but one member has find/create a fix.
1. Make sure the phone is rooted
2. Connect the phone to your PC.
3. using adb shell type
su -
dd if=/sdcard/stl5.rfs of=/dev/block/stl5
4. Reset your phone
Second Fix
1. turn of device
2. press power button + home button
3. run Factory Reset
4. insert again your unlock code
Iam now searching with a team for a third fix.
We have an HEX-editor and 3 Android Developer and me as Android developer.
I hope that we can release soon a fix but you need to know that we dont have a bricked phone!

Hi,
I have a Samsung Galaxy Gio, and the app seems to run and do 'something'. Far from the 60 seconds of blank screen, maybe 2 seconds if even that.
The app does generate 4 lines of codes, as in the screenshot. Items that are unlocked on the phone are filled with zero's. So it appears that each code corresponds to one of the locks (simlock and 'SP'? lock).
After entering the code (with a valid sim) #7465625*638*# the dial field is empty again, this the point when to enter the 8 digit code?
Also, (and I will search some more on this subject later) is it possible that the SP code is the unfreeze code? I wonder about this because I accidentally eentered a wrong code with different network sim in it. I stupidly thought it was asking for the pin-code :S
Generally speaking, how often may you enter a unlock code, can you see the 'freeze' counter somewhere? Does it have some sort of cooldown?
I am searching for the freeze answers here now, so I may edit the post when I have found it
P.S. Is there more info about this app somewhere? I'm curious about how it finds the info to unlock the phone, as this series of phones doesn't have the 'efs' folder as the S series seem to have.
UPDATE!
Before running the program, the phone was pretty much 'factory resetted'. I ran the app, wrote down the code, but didn't use it for anything. I'm not sure when I checked the simlock status, but I had 1010 (binary) and I guess it must have been before running the app. I then did a nother factory reset, and ran the app again; just to see if it would generate the same codes. It did.
Since I wanted to search about for the unfreeze code, I checked the status of the lock again ... both where now gone!!
So not only does this app most likly generate the proper codes, it also appears to remove both locks!
I guess the app could have installed some backdoor or something but on a rooted phone, it works!

The App install nothing but it needs root because he need reading files in the android system files.
Fine to hear that this app works for you!
btw this guy makes also a free version for Galaxy S unlock

Yeah, the problem is though, the app unlocked the phone and displayed the codes. I did not enter them. I did enter the code you listed above to get to the 'enter code now' screen so to say, but i never entered anything.
I guess it's all about trust I wonder though where he obtained the information on the phone, since the gio doesn't have nv_data or /efs. I'm still very happy though
Thank you for program

This app may actually brick/reset certain things. I found that my imei now actually reads 00000000 as wel as having all my mac adreses reset.

My IMEI isnt resetted and my mac isnt too.
You say in an earlier post that your phone was freezed? Because too much wrong unlock codes?this app dont write things he read only IMEI and generate code.
I hope that you can reset your IMEI ;-)
My phone was not frozen, I was affraid I might freeze it, so I didn't enter the key yet.
Basically I only ran it.
What happens on Gio's anyway is, that the App does a dd if=/dev/block/stl5 of=/sdcard/Galaxy_Ace_Unlock/stl5.rfs
READING, as the app is doing, from the 'efs' partition causes something to go wrong and it borkes the efs partition! That is why my phone was unlocked, as the lock is stored in the efs partition!!

Specialy for you i reflash my phone back to GingerBread and i formatted my SD card.
After the flash i check my lockstatus and all things stays on OFF.
This tool need only files to read your IMEI and generate an unlock Code.
I think its safe and its works for me.
When you're afraid for freezing your phone i will advertise you to try an unlock service.
Thats not free but you got a guaranteed unlock tool.
Good luck
Thanks for this guide on how to unlock the Samsung GIO. I have already tried several methods to unlock using the apps provided on this forum to unlock Samsung Galaxy phones. However on my GIO the efs folder doesn't excist and therefore the methods I found didn't work. When I get home from work I'll try the unlock method as described above. If it works I'd be very happy . You'll hear from me.
Grat news... I tried the above things. I downloaded Galaxy_Ace_Unlock as apk, copied it onto my SDcard and installed it on my GIO using an app installer. I got 4 codes, from which 2 of them looked like working codes. I haven't tried the codes and rebooted my phone. I just wanted to make sure my phone wasn't broken after using the app and guess what, it did break my phone. Whenever I try to boot my phone it stucks @ flashing loadscreen. I can't get past the flashes, even when I attach my usb cable that's connected to my computer it won't get passen anything.
Help me out here, is there ANY way to reset my phone back to original factory settings?
I have no phone filesystem backup or whatever, I just ran the app as specified above and did NOT enter any code.
What can I do?
My phone also boot-loops!
I successfully rooted the phone and ran this application, it successfully read one code. I didn't do anything else then, didn't enter any code but instead I restarted the phone to change sim-card. But then the phone just boot-loops.
This is pretty much a direct KANG of my work with no thanks or anything.
Here is how its done for those who care.
this.os.writeBytes("dd if=/dev/block/stl5 of=/sdcard/Galaxy_Ace_Unlock/stl5.rfs\n");
this.os.flush();
this.os.writeBytes("cd /sdcard/Galaxy_Ace_Unlock/\n");

Hehe, so you think it's weird that I come here to ask how to solve the bootloop after using the APP? Sorry but is it also possible to restore back to Factory settings or anything or to restore a phone that is totally unusable after this? I can only load download mode and emergency mode now. I have searched this forum but can't find any help on how to restore back. I'd be up to restore back and then retry your method and thanks you greatly after removing my lock then . Don't understand me wrong, I'm only hoping you can also help me out after my phone is bricked atm. No hard feelings, it's my own fault after all for using someone else's code. I'm a programmer after all and I know how things can depend on device specific things .
Anyway thanks in advance, I'd like to hear from u soon!
This is what I did find on the forum:
using dd command on stl5 is bricking the phone: UNSAFE METHOD
Ok. For good comparison I attached both perso.txt: before and after unlock.
Perhaps that helps. My network was locked to 20404 and the unlock code is 61493638
and there is another code in the file: 92427358 but I don't know what that one does.
Perhaps it is better practise to follow this road for getting the codes:
- adb shell
- su
- dd if=/dev/block/stl5 of=/sdcard/stl5.rfs bs=4096
Then use winimage or similar to examine /sdcard/stl5.rfs as FAT16 image file.

I hope it is not a direct rip from your idea as it bricks phones
the thread linked earlier confirms it. dd-ing the unmount efs partition on a 'normally' running phone causes it to corrupt the efs partition.
Personally, I still have not rebooted my phone, until I have found a solution so that it is not stuck in a reboot loop. Be it as it may, I will remove my root and put it back to default settings and return it hopefully under warranty to reset the IMEI. The phone is just over a week old :S
So are there any ideas on how to restore a corrupted efs by using the DD method as described before? My phone is just 4 days old and already teared apart now . I'm looking on all fora I can find but nowhere there is an explanation to be found on how to reset all of this.

IF you have backed up the efs partition, you can use odin. But since its nearly impossible to backup (may be in emergency boot mode, you actually can read) you actually brick your phone from performing said backup. I don't think the repair tool has been leaked yet (e.g. an efs generator of sorts) so it's pretty much impossible to do this at home. The only way to fix it is to have a certified repair technician fix it, as he has the tools (hopefully) to do this.
Lastly, this tool should be deleted from the firstpost. Helroz has already removed it from his site, since it does corrupt phones.

[Q] Phone locked due to Fingerprint Swipe. Help!

OK so my mother decides to buy the same phone I have, the Galaxy Note 4. She thought she'd put on the fingerprint lock, which worked fine, then for some reason, stopped working. She claims she did not set up a backup password, so therefore I cannot see a way to get into the phone. I did find a zip to flash that would supposedly remove the fingerprint lock, but upon booting into recovery and into the option to apply an update from an SD card (I forgot the exact text), it gave me a message that dm-verity verification failed and I could not apply an update from the drive. What can I do to fix this? I don't want to have to FDR, but if that's the only options, I might bite the bullet and do that.

I'm not sure about this but I don't think an FDR will fix your problem either. I remember someone else having a similar issue with the fingerprint reader and after trial and error we figured out that an FDR doesn't touch the files used to manage the reader.
I don't think Fingerprint lock will allow you to use it unless you enter a backup password. In any case, if a factory reset doesn't work, you might try taking it to you mom's carrier and see if they can unlock it for you. They'll be able to identify that the phone belongs to her account and maybe have the tools to reset it. Try giving the carrier a call. Other than that, I have no idea.

Yes, I advised her to take it to the Verizon store where she got it for assistance. She just assumed that I could help her with everything (literally) since she has the same phone...but not that, unfortunately.
You cant use the fingerprint lock without a backup password. it wont let you use it without one, in case the fingerprint doesnt work. If on the lockscreen you see "Enter backup password" that means she entered it. The backup password is 6 character long with a number, it didnt require any caps letter.

PIN/Pattern required to enable fingerprint

Why is it when I set a fingerprint, I set a pattern for the mandatory backup security but when I try to unlock with fingerprint it asks for a pattern saying "Pattern required to enable fingerprint"?
As far as I know, as an extra security, a pattern/pin code is necessary when the phone is restarted/ switched on, once you chose to use the fingerprint scanner.

Finally figured it out.
It happens when screen is locked by a 3rd party app, in my case I use nova double tap to lock screen.
Was wondering why (and forgot to mention) it seemed random.
Edit: for Nova users looking for a workaround, if you enable screen off by root access method it will use a secure lock and enable the fingerprint to unlock.

yeah a lot of screenapp does ask.... if you are on elementalx you could use button mapper which gives you the same functionality of double to sleep and more doesn't ask for patter/pin everytime you unlock
This started to happen to me after a bug crashed the phone and had to force restart it holding volume down + power. I only have the default launcher so I guess it's factory reset time for me

For what it's worth, I had the same issue (until I found this thread) and it was caused by Action Laucher 3. The launcher was set as a Device Administrator and was granted permission to "Power screen off". Once I removed that permission my troubles were over.
Seems to me that it makes sense once you have a fingerprint setup, to require a pin as well. Why? Because what if the fingerprint reader stops working? You won't be able to login?!?!
Not sure until the poster above mentions a pattern is required. Normally it is a pin if you want. Then the PIN required upon restart option as well that is there.
Of course, if you are rooted, you can delete the system files that control/store that...but if not rooted with TWRP, you would have to try a master reset I would assume?!?!
IDK...guess I never thought of testing that out...haha
Guys, i hope it's ok if i conquer this thread for my question but i got serious issues here.
Got my 10 back from repair today and restored my backup.
But dumb me it seems as if i set a password/patern whatever and i can't remember it.
So after the first restart i can't unlock my phone cause it's asking for the code (and won't let unlock only with fingerprint) and i can't remember.
All combination that i would have used are wrong and now i got a working phone back again (after almost 2 month of repairing) and can't unlock it.
Is there any way of bypassing/ignoring the restart password or is it possible to only unlock it again with the fingerprint that is stored?
As i don't know what i should do if i don't get my phone unlocked

Try a factory reset via Android Device Manager.
I don't know what Android Device Manager is but I could do the reset in TWRP too. It's about not losing all of my data or a possibility to get that device unlocked without the code. It would be no problem as my fingerprint is stored. Damn, I could just hit my head against a wall or alternatively just cry like a baby. I never forgot a password or code in my whole life and by now it happens

To be honest, I don't think so. There were loopholes before, but they have been closed. :/
So doing a factory reset and restoring /data is the only way of getting back control of my phone again (without losing too much data)?
I think i will get rid of locking my phone with fingerprint again as there seems not ot be a failsafe mechanic for forgetting a (backup) mechanic
OK, so it seems that I have to throw that piece of aluminum against the wall. The code seems to interact with /data, because after restoring only /data I have to put in the forgotten password again.

I really suggest starting from zero, when you get everything set, then set a password.
Thanks for your advice, but it's not about starting from zero. I've already done this twice today

LG G4 Not working after firmware issue

Im looking for advice as my brothers LG G4 is no longer working. My brother passed away in May of this year and no one is aware of the draw pattern to unlock the phone. I attempted to use an online tool called Dr.Fone to take the passcode off, however this didnt work. The firmware update screen froze and nothing would move so i removed the battery to restart it. On restarting it, the screen began to change colour and the touchscreen wouldnt work, although it takes you to the draw pattern screen. Im at a loss with what to do, as I cant loose the data on the phone and a hard reset isnt an option. If theres an suggestions id be grateful.
You cant do anything then. Android isnt as stupid as it used to be

Backing up your data can be done with DLM backup (check my sig)!
Removing the screen lock is possible in TWRP if you have it.. If not its maybe possible in download mode but this requires Linux or best FWUL (check my sig) as here all tools needed already included!
Depending on what you have i can share details but first i need to know :
Do you have TWRP and so your device is unlocked?
Do you have Linux AND do you have the knowledge to use it? If you can't answer BOTH with "yes" download FWUL first.
sfX
Il be honest that i have absolutely no idea what they are. Im not technically savvy when it comes to phones and things of the sort.
As far as i can explain, the touchscreen wont work and anytime you press the home button the screen lights up, but you cant actually use it. Im not sure if the term bricked applies as it sounds potentially along those lines?
Id probably need a step by step to sort it without getting to the point of being unable to salvage it.

With your DLM back up, i could transfer all the data onto a USB, wipe the phone then reapply it all? Would that be a possibilty?

In theory yes. It depends on the firmware and device model if it works or not.. Some firmwares are more locked down then others but for 8 of 10 it works.

Encryption

I have the unlocked Pixel 3a XL and would like to encrypt the phone. As far as I have been able to tell, that is not possible with the standard ROM and I would have to wait for another ROM? I do prefer LineageOS since previous phones. Of course, I would also then need to install TWRP which would also need to handle encrypted partitions.
The stock ROM supports encryption, which is typically enabled by default. You can check that it's enabled here:
Settings > Security & Location > Advanced > Encryption & Credentials

I did see that but since I do not enter a passphrase when I turn on the phone I am not sure what exactly, if anything, is encrypted?? The PIN on the lock-screen does not count, of course.
That's normal. Everything is still encrypted/inaccessible until you enter your PIN or password. It's a feature called direct boot that was added in 7.0. https://developer.android.com/training/articles/direct-boot

I looked at that quickly but it does not seem equivalent to encrypting the entire partition which is what I am looking for.
In that case, you'll need to wait for a rom that supports full disk encryption.

Thank you, that is what I surmised. Waiting for LOS and TWRP and for them to support partition encryption.
I am concerned now after reading this. I factory reset a phone that did not have a pin or any lock screen at all. I need to return it and cancel lease since I bought a new 3a with unlocked bootloader.
Is the data recoverable? If so, can I make a pin and do another factory reset and would that be sufficient for privacy? I have all my passwords on Roboform.

If you removed your Google account before resetting you're safe. If you did not then log back in, delete your account from the device and factory reset again. I doubt anyone really cares if you are returning it to a carrier. If you are sending it back to a third party I'd be a little more careful.
The dirty trick is to remove your account, leave password on it, the reset from recovery. That will trigger a full wipe.

Edit: I guess things have change with device encrypted vs credential encrypted.

There used to be a way to force a pin on startup before boot. Is that option gone? Haven't used it in years since it was such a pain.

I am not sure anything changed, encrypting partitions have always been the best - and only real - way of protecting your device. The PINs etc. are eye candy.

You put on a pin, use the fingerprint scanner for bank accounts, good passwords, what else can you do? A thief will go for the person that has none of these, there are many devices for them to choose from.
If you are that concerned then keep the information off the device. No one wants your stuff as much as you think they do. If I have to encrypt my phone I might as well leave it home or use a pen and paper.

Our needs and concerns are obviously different. I think it is clear that encryption is recommended by knowledgeable people.

Obviously. But I'm sure you can find a company and device that suits your needs.
