I recently read a thread about unlocking your phone for any sim for free, and it seems great!
Just wondering if turning the SHA256 off is a bad idea for security reasons, since doesnt that encrypt your passwords?
Im not fully informed about all of this, just know some stuff about the SHA256 one way hashing to encrypt passwords
Id love to unlock my phone for free, but wondering if there is a risk
Any info would be great.
Cheers

I've been asking myself the same question ever since I did unlock my phone using that same method.
The "how to" doesn't say to re-enable SHA256, so I didn't do it.
Should we?

I think if we re-enable it, the whole process will be defunct. But I dont know
I just switched carriers and love that I can unlock for free, but if there is a major security risk. Then whats the cost?
I'm going to unlock anyhow haha .... but I won't be installing any 3rd party apps until I know for sure
Update
So I did it. Followed instructions and turned off SHA256, and then inserted a sim from different carrier. It worked, but only sort of. I kept getting "Emergency Calls Only" Then it would switch back to the carrier and everything would work, then back to not working
I went in to the settings again and turned SHA256 back 'ON'
Did a full factory reset of the device. When it booted back up and I set up all my accounts again, the phone works perfectly. Connects flawlessly to the new carrier, AND, this is the weird part, it says my SHA256 is still turned 'ON'
Straaange
ok, but why did you factory reset your phone for ?

Because I panicked haha. The new carrier was working, then not working, then working then not. So I tried to reset all the settings, especially the SHA256, thinking a factory reset would do all that, then try it all again. And for some reason after I set all my accounts back up after the restore, the new carrier worked.
If you ever decide to want to revert this changes read this post:
http://forum.xda-developers.com/showpost.php?p=36819261&postcount=4
so i did this and now note had circle bar , cannot get any signal is not asking me for ecode wont work for att my note is i317 anyone know what i neeed to do
For me, turning SHA256 OFF didn't give me the unlock option. But I had seen a Youtube tutorial where they hit SHA256 ON instead of off, and they got the option. So, OFF (then wait 30 seconds, then go back) didn't work for me, I hit SHA256 ON (waited, back) & got the NV INITIALIZ option. My SGS3 is currently working on a T-Mobile MVNO. Never even inserted the AT&T SIM they gave me.
Is it safe or not
Hello
I would like to unlock my Samsung Galaxy S3 and I saw many articles which include a "Perso SHA256 Off".
Does it remove password encryption or does it have any other consequences?
Please help - Sold OnePlus 3 on eBay - Buyer is stuck on "This device was reset"
Please help - Sold OnePlus 3 on eBay - Buyer is stuck on "This device was reset" even though I have reset/wiped the device.
What can i do to help them?
The device was sent on the latest OxygenOS.
Thank you so much in advance.
I believe you would need to login to the phone.
The bypass menu only comes up if you reset with either a screen lock active or a google account on the device when you reset.
I am sure when it first came out there was a way around messing with the keyboard or something, but I am unsure if this was patched or not?
this is a google security feature - you need to log into the phone.
best way to do this might be to have them log into the phone and immediately change your account passwords afterwards. not sure what else

Why don't you tell them to turn off the phone, power + volume down, select forgot password and wipe the device? That should be enough to get rid of all previous account data

This system uses a special partition to "flag" the device as protected from factory resets. These will not work.

I work retail and return phones every day; we NEED to remove the accounts before wiping the device, or else the only reasonable way after wiping the device is logging into the account. 2x4 is right.

Exactly the system, wipe the device by flashing Open Beta or unlock the bootloader and flash a custom ROM and wipe everything, reload stock recovery, wipe everything then sideload 4.1.6.
Working retail you can't play around with phones the same as I would with my own phone so you're dealing in a completely different environment.
There are options in place in case someone messes up its not unrecoverable

Will not be able to unlock the bootloader anymore, it needs to be enabled in the OS. If it's not already unlocked it's not going to be.
I also doubt flashing stock OOS would remove the FRP, that would kind of defeat the purpose of having FRP in the first place if you could just go to the OEM's website and flash something in 5 mins.
Why not simply use the unbrick tool? That should return the phone in a factory-like state.

1) Check this article to see if you can remotely remove the device from your end (never tried this myself): https://help.ting.com/hc/en-us/articles/205666168-Removing-Android-Activation-Lock
2) Assuming your account is not full of sensitive data, change your Google password temporarily and give it to the buyer (may be easier to call or live chat them if possible). Once they get in, change your password back. Not exactly safe, I probably wouldn't do this myself. If you do be sure to take caution- 2 step your account after, force log out all devices to your account.
3) Cough up the shipping cost to return the item and try to sell it again. Unfortunately you would have to pay the return fee + lose the original shipping fee.
TIP: Before selling a device, DO NOT factory reset it then box it up without turning it on. Factory reset, THEN test to be sure it goes to the home screen and working properly. You can then reset it again or sell it at the home screen after skipping the setup steps.
For reference to others reading this thread - always REMOVE your accounts BEFORE factory reset of your devices prior to selling to avoid this issue.
There are lots of ways to bypass this on YouTube. I actually did it yesterday. I had to unlock a tablet. If adb is enabled, it's piece of cake.
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.

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.

Hi All,
I have T-Mobile version of S20, which was unlocked long time ago. I recently switched to Verizon and the phone working perfectly fine. This morning I received security update for May 2021 from T-mobile and after that phone is not able to connect to network. Verizon technician tried troubleshooting, but they asked me to do a factory reset.
Does anyone know how to connect back to network with factory reset?
Thanks in advance.
Wow, it's really secure now
So the old factory reset solves everything bs solution... I tend to curse techs out if they mutter those words.
Before you go Dr Strangelove full nuke nuts:
Try clearing the system cache
Try a network reset
Try clearing the data in the sim card toolkit
Then try a hard reboot (simulates pulling battery).

Thanks for reply, but so far I have already tried clearing system cache, network reset, setting reset and hard reboot (can't do battery pull in new Samsung Lol). I am thinking of flashing t-mobile or verizon firmware using odin.

That sucks. I haven't updated my Note 10+ in over a year, deliberately. Zero issues.
The reflash sounds like a plan.
Since you're doing that anyway see what the factory reset does. Unless it's an old load I try to avoid doing that and find the root cause to prevent it from happening again.
In this case though you know the root cause...

Did the factory reset, but it didn't work. Trying to get correct firmware to flash using odin.
I flashed Verizon version of firmware downloaded from Sammobile.com using Moded Odin provided in this thread that fixed the phone. https://forum.xda-developers.com/t/...e-links-and-flashing-discussion-here.4054757/
Data was lost because of factory reset I did already.
Report the issue to Samsung Members app, I've seen other people who switched carriers while keeping their devices face the same sort of problem. If Samsung does come up with some sort of solution or maybe the carrier comes up with a solution, you can be kept up to date with it.

I had the same problem. Did a reset and nothing. I haven't flashed any firmware in a while. I have another phone that I can use for a while and maybe I can wait until there is a solution or another update. My s20 is also from tmobile unlocked.

Any direct link to the Verizon firmware or the name of the file that you downloaded? There are many files for different processors. I have the T-mobile S20 bought in T-mobile and was unlocked via T-mobile after I payed for it.
UGGG!! Same problem here. T-mobile seems to have had something in the update that has carrier locked the phone again. After a complete data reset the phone doest ask for a Verizon pin when I insert the sim card though.
Please help!!
Hi i have the oneplus 9 pro LE2125 using it on AT&T its default the radio setting's via engineering mode is LTE/TDSCDMA/GSM/WCDMA and i am not getting a good signal on it.any advice on which settings i could maximize the signal..or is there anyone that could share what is the default settings on their device using AT&T..Thanks
You could try AT&T advanced tech support, hit or miss but sometimes you get a good tech.

Clear sim toolkit data, network reset and clear system cache.
That's the most I had to do but there's more if that doesn't work. Try advanced tech support again, get them to reset it on their end.
