Possible to set TRWP password? - Samsung Galaxy S8 Questions and Answers

Hello everyone,
I ve been thinking that my rooted phone with TRWP is not really protected. You can easily boot intro recovery without any password and steal/wipe all the data and install new rom. Is there a way to protect the rooted phone somehow? Like setting a password for TRWP. Thanks in advance.

Don't think it matters that much. They still can boot into Download mode and flash a new one.

So basicly there is no way to protect S8 from that kind of attack? Because I think you can boot into Download mode even on stock firmware.

OEM Protection in developers settings ? I think we can't do anything if it is enabled

Samsung reactivation lock. Even if you wipe all data/cache and flash a new stock it will still ask for the password that was used last. I know this because Im locked out of my s6 because of it ?

Thank you for the info. So it actually asks for pin or password that was used previously to unlock the phone? Or we need to enable it somewhere in the options?

Yeah enable it in Samsung account. Or use secure start-up. With either of these it will always ask for pin or password even after flashing stock Rom
EDIT: I'm pretty sure Google does the same and asks for previous used account password.

Completely bricked. BL unlocked, TWRP installed. Won't boot

Thought I was good at this. Never mind.
So I have managed to brick my device after 6 hours of having it.
Managed to unlock the BL, install TWRP, but the OS has gone, and I have no way of getting the thing mounted to copy over a ROM or anything.
What's the best way for me to sort this out ?
I'm thinking I could buy an SD card, copy a ROM to it, then flash it via TWRP.
Is this the only option ?
Help

If you can get to the bootloader then just use the restore to stock tool from shawn5162. Should work fine as long as you have successfully unlocked the bootloader. Here is the link http://forum.xda-developers.com/moto-x-style/development/windows-tool-moto-x-style-pure-edition-t3199905
Should be clear that this will put your device to LP 5.1.1 without root or TWRP. Then just do the OTA MM update and re-root and flash TWRP. You can follow this guide I created if you like.

I have never had such issues when setting up a phone before. Now I have this message
"there's a problem signing in to your google account on this device
Please sign in from a browser on your computer or tablet first, then try signing in again on this device"
Needless to say, I've done this numerous times, and I still cannot sign in on the phone.
Ugh.

Ouch...Thats a security feature on MM... Only way ive found to avoid it is to restore a backup and before you wipe/flash your next ROM either disable the lockscreen(i.e. unsecured lockscreen), re-enable OEM unlocking, or factory reset your device from it from your running phone(not in TWRP) through settings->Backup and reset...that removes your google account from your phone so once you reset it you can set your phone up with your google account

Think I'm screwed. No backup. No ability to log into the OS to reset from within. Just keeps looping on the input screen.
I think I read somewhere that if you wait 72 hours it fixes itself. We'll see.

Why not use the restore to stock tool then before taking the update just make sure your phone has no security on it or the OEM unnlocked turned on...

hmmm thats weird... the new security feature wasn't implemented until MM... The restore to stock should take you to 5.1.1. not sure what else to try. Hopefully you can get in after the wait...next time you get your phone running make a backup to save a headache down the road
edit: you couldnt use the restore to stock then before it loads flash a 5.1 ROM?

Its the stock TWRP backup from either 5.1.1 or 6.0....whichever you are currently supposed to be on.
wait, if this is a new phone and you had added your google account before "bricking," why cant you just sign in using that google account. My understanding is that the lockout is to prevent a NEW google account that was not associated with your phone from being used to set it up

That error means you don't have a 72 hour lock yet. Go to https://accounts.google.com/b/0/displayunlockcaptcha on your computer. Login, hit the accept button, then try logging in your phone. Your phone is not locked out, just to to the website. If you changed your password, though, then you shot yourself in the foot with the Google protection.

Need help making a factory reset

Hello!
I just got a Nexus 6P from a friend of mine who unfortunately is no longer with us. However, I can't unlock it. Nobody knows the password (nobody ever will), so I tried to wipe the data through the recovery. It didn't work at all. The downloaded apps might have been deleted, but the Google account is still active and also the password.
The USB debugging is turned off and I can't activate it while it's locked, so I don't know what to do now. I've been searching for days and I wonder if there is a way to activate the USB debugging from the outside.
Thank you for reading this.
Maybe gry to flash stock again?
https://developers.google.com/android/images
Here is download link and instruction
With or without USB Debugging, it still won't work for you.
The device will need the password of the previous owner to login after a factory reset.
It's called FRP Lock.
The phone is only good for parts part it out..

FRP

I bought a Nexus 6P and after I factory reseted it requests for account. I don't have any more contact with the man who sold me because he has no smartphone for now.
It has the January security patch.
Is there any somehow I can bypass FRP in January Patch?
I saw at YouTube that is able to bypass it with October patch, but couldn't find anything for January.
Thanks.

Hello,
The exploit has been patched. No new FRP bypass available.
Question... The guy sold you his N6P with his account on the phone that you have FRP after factory reset? Cool story...
I wonder who sell a phone with his account left on the phone..?
Good luck...

He sold me and we did a factory reset. The battery was low so I arrived home to boot up and configure the device while charging, but got stuck in this.
Also, I found a way to bypass it and use the device without Google Account. If I unlock bootloader, complete wipe and install a custom ROM, would the account still be required?

Hey,
Normally, if you enable OEM unlock, unlock bootloader, you may be able to skip setup and add your account.
I usually wipe my phone with OEM unlock enabled and no SETUP/account required. With OEM unlock disabled, setup/account required, even with the bootloader unlocked...
Hmm, so you were able to enable OEM unlock? How did you do, since you can't skip setup, or? And if you skipped setup, you should be able to delete the previous account from settings without issue. I'm confused...
Cheers...

My friend found a way to skip all the initial configuration.
I can go in any setup, install apps via aptoide, etc.
If I enable OEM Unlock and install a Custom ROM will I be able to fully use my new device?

Hey,
Did it involve the use of ADB by the way?
Also, if you got in settings, you can go in account and add yours, no?
Anyway... To my knowledge, when I let OEM unlock disabled and wipe, reflash, I have to add my account after the install. If OEM unlock is left enabled, I can skip setup.
Only way to figure it out is trying by yourself... :good:
Hopefully it will work.

This is how it works anyway. If you enable OEM unlock, the phone ask if you're really sure you want to enable it, and it will disable security feature = FRP...

Recover Photos, Broken Screen or Forgotten Passcode

Hi, I've got 2 phones I want to get the photos off.
An S7 Edge with a broken LCD (can't see anything)
An S6 with a forgotten passcode.
What would you guys suggest? I toyed around with a trial of dr.phone and was able to preview photos on the S6, but I would prefer to find a free way. And dr.phone & fonepaw do not support the s7 edge.
Would a custom recovery like TWRP work? or does that require full access to the phone? (ie turn on debug mode etc)
Thanks in advance?
Abut the S6EDGE I can give you a suggest
Unlock your bootloader first(Require remove the Google/Samsung account,if you login these account your phone before,this way is didnt work)
secound flash the twrp,then you mount your phone and copy photos out to your pc.
Another way:You can contact with some Shenzhen(China) company,they have a lots of way to unlock your phone.hahahahaha

Thanks for the reply. So to flash TWRP I need to unlock the bootloader first? Is this something I can do without the passcode? I did a quick google, and it said the option is under the developer options menu.

Can a custom rom remove a pin coded lock screen S8 SM-G950F?

Hi all
Android Recovery
samsung/dreamltexx/dreamlte
8.0.0/R16NW/G950FXXU4CRL2
Flashed firmware today from G950FXXU4CRJ5 to G950FXXU4CRL2
Also an Exynos not Snapdragon
I have another post on the go https://forum.xda-developers.com/showthread.php?t=3967187
I am trying to get in to my mum's phone which she has been locked out of by her nasty ex husband. It has a 6 digit pin code for the lock screen.
I have tried flashing same and new firmware as I thought maybe that will reset some settings but it didn't.
She has photos on there that she doesn't want to lose... and I cannot guarantee that they can be saved if we do a factory reset.
Is there a chance that if a custom rom was flashed it would make the phone accessable so I can get any files I want from it?
The phone is Australian so I am guessing I cannot just flash any old files, like with flashing firmware.
Any help would be greatly appreciated.
Cheers

Custom roms have different user partition therefore not compatible with stock rom. But if you have twrp installed you can remove the files wich store the lock info , simply reboot to twrp go to filemanager browse to /data/system and remove all files with .key extension and files named locksettings

do not flash a ROM. The storage has a very strong possibility of overwriting the pictures. Best thing you can do is boot it into DL mode, throw TWRP on it, allow superuser access within TWRP and ADB into it. Also, just because it is an Australian market phone doesnt mean it needs some special firmware. You can flash pretty much any 950F firmware on it

Unfortunately my mum is not tech savvy so TWRP is not installed, developer options not active and oem unlock not unlocked.
Yes that is all I want to do is access files to delete lock screen files.

Can you install TWRP through DL mode? I think I tried and it came back with FRP lock. I will try again though... can you recommend a version or TWRP that will work through DL mode please? If not I'll have a search for one.
I tried to flash UK firmware and it didn't work, but thats not an issue.
Once I have TWRP I'll be sorted, its just getting it on there to enable me to ADB in to it. Will I be able to ADB in to it if OEM is not unlocked etc...
Thanks for your reply
If you have frp lock on. Im sorry to say that you must wipe the data

im sorry to say this, but youre probably effed with FRP lock enabled and no develpoer options enabled, so without paying for an unlock service outside of XDA, which very well might cause this post to get removed. Ill tag someone who might be able to help, but if he can help, it will cost you some money. @Nodial you and your colleagues have any methods to help this fella out?
Thanks for the replies guys, yes I had a feeling when I came across the FRP error I would of hit the end of the road...
Might have to either bite the bullet and pay up or factory reset and see what I can recover.
Thanks again guys
