168+ hours of uptime and no OEM Unlock! - Samsung Galaxy A8+ (2018) Questions & Answers

I have a SM-A730F (brazilian version, the carrier is Vivo) running stock, never flashed anything on it. I've done a few tries of maintaining this uptime already and never got the OEM Unlock setting to show. Can someone help me?
Thanks in advance

Is this phone bought factory unlocked or is it bought from a from a phone company example t.mobile.
It possible it is unlock able.

I do already have dev options enabled, but can't see OEM Unlock there. It is not bought from a carrier, I bought it straight from Samsung and can change carrier simply by replacing the SIM card

Factory reset

Will do. Is that the same as a hard reset? This erases all my data, such as pictures and stuff, right?
PS: Found out that my mother's phone, which was bought together with mine and is the exact same model, has an uptime of almost 900 hours and also don't have OEM Unlock available in dev settings. She also have never flashed anything on it.

When it boots up is their any other logo their besides Samsung?
Reset or hard reset is the same do it from stock recovery .

There are 2 Samsung logos. First a still image that says Samsung Galaxy A8+ Powered by Android, then a Samsung splash

That is normal I bought mine from China and been rooted since day one.
If you can't get oem unlock to show ireally don't know what to say.
I did not follow root directions I did it my way.
When you put a Sim card it activates rmm state lock that hides your oem unlock.
You can try a hard rest for 168 hour no reboot and don't disconnect from network if you do you have to start over.
Here is a long shot you can try remove Sim card and do a hard reset and reboot see if you can see oem unlock.

[Q] Unable to unlock phone

So, basically, I got a new pay-as-you-go SIM and I don't want to buy a new phone for it. I was looking for methods to unlock my current galaxy ace, it's rooted and I have a custom ROM on it- The Ultimatum by The "A" Factor. I got my unlock codes and put the SIM in expecting to get a screen saying phone is locked, please put in unlock code or something similar that usually happens. However nothing came up but when the phone finished booting, I had no service and can't use it for calls or anything which suggests that the phone is still locked, I tried using the *#7465525# service code, but I got an error saying no service or incorrect MUDI code or something like that. Is it possible that flashing a new ROM wiped the unlocking procedures and is there anyway for me to know if my phone is unlocked and if not, can I still unlock it?

Didn't show you nothing to introduce the code?¿
... try introducing another SIM from other carrier... when you boot then automatically should ask you to introduce the unlock code
If it doesn't work you could phone to the device's carrier, the carrier must help you if you finished your contract

I do have another SIM from another carrier, but the screen isn't showing up, I've been scouring the internet and found http://forum.xda-developers.com/showthread.php?t=1335548 , turns out it won't show because of my ROM, so I'll have to switch to stock like you said, before I do that though I'll try that code he said at the end to see if it will unlock. Thanks :good:

ok! be carefull with this stuff, you could brick your device if you do something wrong, if I were you I'd phone my carrier to avoid any kind of trouble (if I'd had my contract finished)

Help! Phone stuck at boot screen, power button only restarts phone!!

UPDATE:
OK I'M BACK INTO RECOVERY.
Now can I erase the bootloader and everything and reload all of it without having the phone unlocked?
When I try and do "fastboot oem unlock" it comes back with an error and says "I Must have OEM Unlocked in Developer Options. That's great, but I can't get the phone to boot into android so what should I do at this point?
I don't want to try and erase everything and reload it just to find out i've seriously messed it up at this point, even though the silly thing doesn't load anyways.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
so I received a new Nexus 6 device from T-Mobile for my girlfriend.
In our area unfortunately Wi-Fi calling is a must, so she went ahead and did both of the OTA updates. After doing the second update the phone was stuck optimizing apps, and then the screen wouldn't work...
So I then hooked the phone up to the PC and through ADB did the following commands
fastboot erase userdata
fastboot erase cache
That was supposedly the commands I had found on the internet to go ahead and factory reset the phone.
Now the phone is stuck at the balls swirling and it won't stop. Try and hold the power button down and the phone just restarts itself, won't shut down so I can't even get back into the recovery.
I tried to first load up a factory image before doing something silly like that but when I tried to run the command "fasboot oem unlock" it says I need to enable developer options in Android... which I couldn't get to anyways...
Can someone please help with this issue. Her old phone got stolen and now she has this one which is completely messed up.
Thank you for anyone who can help me!

You have to hold power and down on the bottom button, or since you have adb, you can do "adb reboot recovery". Push volume down first then power. After that you can enable MTP and toss a rom on the phone. Do a complete wipe with the exception of the internal storage ( I did storage one time accidentally, yuk) flash a ROM and you should be good
I can't even turn off the device at this point.... It is just stuck at the balls spinning and won't go any further.
When trying to shut the phone off the power button just restarts the phone, doesn't shut it down. Not sure what is going on.....

It should shut down if hold the power button long enough. Takes like 20 seconds or so.

As far as I know with stock recovery about all you can do is try to format cache and try to factory reset again. Otherwise will have to take back to T-Mobile and RMA. Make them update it. Lot of OTA updates have been failing.
I'm just curious to know if there is someway. Maybe I can force TWRP recovery or something like that on the phone by at least getting in the bootloader... There is a fix for bricking if it is like that.
Why the bootloader just doesn't come unlocked I will not understand. It would prevent motorola from having a heap of useless devices, as i'm sure probably even motorola themselves cannot fix the device.
Seems like a whole pile of sh*t if you ask me.
Anyone have any ideas? Worst part is T-Mobile won't ship a phone over the weekend either, so thats just 3 more days without a phone which is just wonderful.

There is no way to flash a recovery without the bootloader unlocked. On these devices it is best to unlock bootloader first thing before trying to update so have some control if things go bad. Moto has the ability to reflash them like J-Tag. TMobile store may replace it.
Messed up part about T-Mobile is the fact this was an exchange for a stolen phone. They actually waived the insurance fee of $175 and the tax on the phone... which was extremely nice of them since I still owed about $350 on the LG G3 my girlfriend had.
So since the exchange was done over the phone or I should say since the new handset would bought over the phone the store won't replace it... it's weird they operate that way because the store should be able to replace anything that is sold via phone or internet and vice versa.

Yea. It a bad situation. We have seen a lot of them choke on the OTA flash. Best to unlock upfront and fastboot the updated factory image. You are always safe once it is unlocked.
Still begs the question as to why they don't just unlock the bootloader from the factory to avoid all this crap. I mean imagine how much money and time they would save if they just did it? I completely forgot about unlocking the bootloader even because I figured hey just OTA it and be done.... remember it's my girlfriend so I wasn't going to put some ROM on there that might have something broken or whatever... can't believe this **** though.

I understand. They look at unlocked bootloader as a security problem. It even tells you it disabled security when you flip the unlock switch. From the many OTAs we have seen brick it is best to just unlock even if running stock. Once it is up and running can always relock. Do not relock if have custom recovery or kernel tho. It will more than likely bootloop. I tried it for grins but made sure the unlock option was enabled and was able to unlock and reflash. Many have flashed new software and relocked before first boot to find out it bootloops and can't unlock again. Best to have TWRP so that if is locked have a adb/MTP option. We pretty much discourage OTA. I haven't tried but have seen a post that says must be locked to OTA. If that is the case you always have the chance of a bad OTA flash and end up same place you are now. With TWRP there are also OTA files that have been converted to flashable zip and can be flashed in recovery.

Buying possibly locked phone running Android 5 or 6

When buying from ebay dead phone it might be either password, fingerprint or even Google locked (not sure what the last one means).
Would I be able to use it after fixing the screen and hard reset?
Older Androids at least up to 4.4.2 upon the hard reset simply eraze all data and let you use the phone.
What is the situation with Android 5, 6 and 7?

Be careful if the reactivation lock is on from settings you won't be able to use or flash anything no matter if it's on android 4,5, or 6.
Even if you do hard reset when setup the device it will ask for samsung account password.
You must have device owner password to unlock the reactivation lock.
Thanks!

Yes FRP does not seem to be an easy one, so all ebay phones are potentially bricks. BTW FRP was first introduced in 5.1

If the workaround to bring back the oem unlock toggle isn't working, then you will have to wait the 7 days for it to appear. Then you can toggle it and try installing twrp again. You likely missed a step in the process last time which resulted in 'jail'.

Reboots don't affect the 7 day timer. Your uptime timer will reset, but the 7 day timer for OEM unlock is server-side.

I'm not sure but I think that installing the update could restart the 7-day wait period. If you want to root as fast as possible then it's probably safer to not install the update for now and just wait for the OEM Unlock toggle to appear. There is also a stick thread here with a workaround to skip the 7 day waiting period, but it didn't seem to work for everyone (although it did work for me the one time I tried it).
Any luck///need help too.
Any luck with getting the OEM to show?
I've tried them all waiting 7 to 2 weeks, factory reset change date at setting up insert sim card and no luck. I got my note 8 at soon as it came out so maybe it has something to do with it? I want to root it so bad it cant because of no OEM. Any new information would be great!

Damn, sorry I thought I listed it. I have a t mobile note 8 where the OEM wont show up and a unlocked note 9 N9600 where the OEM is grayed out to which I tried Odin flashing N9600 CPT/TCP version (not to sure right early this moment) and the flash passed but the phone was exactly the same without any changes and still the OEM was grayed out. I tried 3 different methods of changing dates on both phones with no luck. Any kind of new information or version ti they and get this OEM to work for me would be greatly appreciated.

Ok the T-Mobile model has a locked bootloader that can't be unlocked, so OEM unlock won't work.
The N9600's bootloader can be unlocked though. I have tried the date trick in the past on another Note 8 variant and it worked, but I have since read different things such as recent firmware updates stopping the trick, or needing to jump more than 30 days ahead instead of 7 to make it work. Not sure if all that's true or not, but if nothing works then I would probably back things up, flash original firmware through Odin with full wipe and wait 7 days to see if OEM unlock appears.

Yes I know the t mobile bootloader cant be unlocked but still can get be rooted and use some mods with the lost of 20% battery lose but one has to get OEM unlocked under developers options (that option never shows up for me) I've tried 7 to 14 day without reboot but not 30. I've give that a try on the note 8.
As for the note 9 N9600, I thought it came unlocked already but still just need the OEM unlock switched, which for me is grayed out and cant be switched. I'll use factory reset on both and try the 30 days trick instead of 7 and see if itll work.
Thanks for the info.

Yeah the samfail method for u.s. snapdragon models was patched by Samsung at one point, but it depends on which version bootloader you currently have installed if I recall correctly. Check through the samfail thread for more info there. I have an exynos, so can't say for sure about n9600 but that's what I would try at this point

I cant do anything without figuring out how to get OEM unlock to show up on my note and OEM unlock option greyed out removed from my note 9. The only step one found was the tricking the device on changing the date and that didnt work on the note 8 (going to try it for 30 plus days and see if thatll work) as for the note 9,,,,,,, I dont know why it's even grayed out.

Like I said you won't get it on the T-Mobile model (and iirc it's not needed for samfail, even if you are on the proper bootloader, etc.), but you can always check the 9600 and/or OEM unlock threads for more on that one if the stock flash/wipe and waiting period approach isn't preferred or doesn't work out.

Bought phone from ebay, now registration wizard won't let me pass

So I bought this phone from eBay, like many before it. But this time it came with a twist: when I booted the phone, initial setup ran and all wend fine until I got to the register Google account screen.
There, the phone says: "This phone was reset. To continue, sign in with a Google Account that was previously synced on this device".
No matter what account I use, I always get a Toast message saying "Unable to sign in to device due to a unknown error. Please try another account or try to sign in again after 24 hours.".
I'm guessing this is some kind of theft protection where entering a previously synced account "proves" that you're the legit owner. The authorised service here told me that I need some kind of proof that I'm the legit owner and surely enough the eBay seller has issued no invoice containing the phone's IMEI (or any similar document).
Anyway, here I am with this gorgeous phone on my hands which is little more than a brick due to this.
Is there any way I could get it to work again? Returning it will just generate more costs for me and I'd like to avoid that.
I've seen guides on youtube where they managed to bypass this security measure, but both methods I've seen failed for me. I guess the version running on my phone is just too recent and plugged all the holes.
Do I have any way of downgrading the software at least? Note that this is a fully locked phone and I can't even start TWRP from fastboot.
Anything else?
Edit: Now that I'm re-reading this post, it occurred to me that there's very little chance that this phone wouldn't be a stolen one. Had it not been, the seller would easily issue me an invoice.
Leaving this post only because my searching hasn't turned up anything on XDA. Probably also reporting the guy on eBay.

From the Settings / About, what is exact (full) build name/number?
Generally, if you are on Nougat then IMO, rolling back to MM should completely reset your phone.
You cannot flash TWRP without unlocking Bootloader. But that will not help much for resetting Google protection.
Btw, enable Developer's menu, does it allow you to unlock FRP/OEM Unlocking - in that case you will be able to reset all from EMUI recovery.

- Boot to Recovery (switch off, press and keep pressing Vol+ and Pow). Does it boot to stock Recovery and does it allow there to Factory reset (it should but if FRP was unlocked)
- Boot to Fastboot (switch off, connect by USB to PC, press Vol- and Pow), do you see Phone (Bootloader) and FRP locked or unlocked?

It is stock recovery. I don't recall the option for factory reset. In fact there's no options at all, save for reboots.
Fastboot says everything is locked as it should be.
Don't know how to downgrade to MM.

Rollback instructions are here

But not sure would it allow you to setup.
That is Factory Reset Protection (FRP/OEM Unlocking) - if it was unlocked you would be allowed to reset from recovery.
You can ask seller - maybe he can login to his Google account and remotely remove Google account from the sold phone.
Or you can try DC Unlocker, not sure would it work

Well, DC unlocker ultimately worked, but not before buying a wrong package, having to ask tech support, etc, etc. Not to mention the guy really has no patience for people who don't have his level of understanding of the subject. Why does he do it then if he hates the whole thing so much?

So did you use DC Unlocker to unlock Bootloader or DC Phoenix to reinstall the phone?

DC unlocker. I wanted minimal impact on the OS as the phone is for my daughter and she doesn't do custom ROMs et al

Sorry for bothering but I'm interested now - when Bootloader was unlocked (and FRP too), were you just able to pass setup or you needed to do Factory reset from Recovery or how did you get the stock ROM working for you
Final resolution: the seller sent me an invoice. I guess that means that the phone wasn't stolen after all since they can only expect that this will be entered into Huawei databases.

The procedure was thus:
1. unlocker unlocked the FRP
2. phone rebooted into a factory reset (low level) mode - it specifically said "low level"
3. phone booted into normal Android where the FRP protection was no longer active. On screen where it previously demanded a previous Google account it now only demanded A (any) Google account as I'm used to from all the other phones I ever bought.
Sorry old post
