I think this has now happened to the Galaxy tab a Sm-t280 which is a spreadtrum sc8830 device.
I have tried everything I know to root or get custom recovery on this device. I have built root and custom recovery for a Spreadtrum sc8830 device before just fine.
However everything I flash on the Sm-t280 displays the *Secure check fail: recovery* warning.
Even stock repacked boot and recovery images don't work. So safe to say I think it's a locked bootloader?
Can anyone confirm my suspicions?
I have rooted and built custom recovery's for many new devices, but this one has me beat.*
Hi, ashyx thanks for your work!
If you want I can test also on my sm-t280
The bootloader is locked. You can't flash anything not signed by Samsung. More devices are coming locked like this.

It seems so, if Samsung carry on this way I for one will not buy another of their products.
I will never buy a bootloader locked device. They should at least offer the option to unlock it like HTC.

With security being such a huge factor these days. Alot of devices are coming with locked bootloader that can't be unlocked. Mainly Samsung who is near the top when it comes to secure devices. It's what they are shooting for.
Yeh you would think that's great for corporate use, but it's not.
In fact it is a company who contacted me via XDA who sent me this tablet to root it and build a custom recovery for it as they need to modify it for their specific use.
They were going to buy 50 of these devices once I had completed the work.
However obviously that's not possible, so looks like they may have to look at a different device.

Subject: Galaxy Tab A 6(2016) SM-T280(UK model) Locked bootloader
Hi I am a developer, I have been given the task of customising the software for this device by a company who wish to purchase 50 of these devices for a specific use. The modifications needed require the device to be rooted. However it seems this device has a locked Bootloader as any unsigned software flashed to the device returns a *SECURE CHECK FAIL: RECOVERY* warning even with OEM UNLOCKING enabled in developer settings.
Could you confirm as soon as possible if this device has a locked Bootloader, so I can cease working on the device and inform the company I am working for?
Many thanks for your help.

[SIZE="+2"]BootUnlocker for Nexus Devices -- Unlock your bootloader without fastboot.[/SIZE]
NEW: beta version available!
This is cross-posted from the the Galaxy Nexus forum, where the app got started. The app supports Galaxy Nexus, Nexus 4, and Nexus 10, and we are working on other Nexus devices. Please direct your support questions to the original thread.
Original Thread: https://forum.xda-developers.com/ga...p-bootunlocker-nexus-devices-version-t1731993
How it Works: https://forum.xda-developers.com/showpost.php?p=73069986&postcount=2
Changelog: https://forum.xda-developers.com/showpost.php?p=73069987&postcount=3
STABLE version: (a) XDA post, (b) XDA download, (c) Google Play download
BETA version: (a) XDA post, (b) XDA download
Description
This application REQUIRES a Galaxy Nexus (maguro, toro or toroplus), Nexus 4 (mako), Nexus 5 (hammerhead), Nexus 7 2013 (deb or flo), Nexus 10 (manta), OnePlus One (bacon / A0001), OnePlus 2 (OnePlus2), or OnePlus X (OnePlus / ONE / E1001), with root.
You've rooted your device, and you are trying to decide between the security of relocking your bootloader (with stock recovery and USB Debugging off), and the flexibility of leaving it unlocked.
You know that in order to prevent an unauthorized user from accessing your data by flashing a custom recovery, "fastboot oem unlock" wipes your data. This also means that if you relock your bootloader, you will need to do a full backup-and-restore whenever you decide to unlock it again.
BootUnlocker for Nexus Devices lets you have the best of both worlds by using root privileges to unlock your bootloader from within Android, without wiping your data. This allows you to keep your bootloader locked for security, with this application safely protected behind your lockscreen password. Whenever you want to unlock or relock your bootloader, just unlock your screen and run BootUnlocker.

I'm rooted with stock ROM, can I use this app to unlock my boot loader and then flash a custom recovery like twrp? All while not losing my data.
I just bought a Nexus10 and after rooting I used this tool to relock the bootloader successfully. Now I can confirm that it works like a charm in both nexus 4 & 10.
Thank you very much!
Sorry, not wanting to thread hi-jack here or anything, but this seems like the best place to mention it. If you've ever had the experience of rebooting to bootloader and you've forgetten to unlock in BootUnlocker first, or, you really screwed something up and can't boot the OS in the first place to unlock with the app, I made a recovery flashable zip that will do the same thing. Always handy to have on hand in case of emergencies.

When I want to flash something I always forgot to unlock before and need to reboot again... Thank you very much for Nexus 4 & 10 versions.
Just a quick note to confirm that this fantastic tool works with the new nexus10 “MANTAMD03“ bootloader (android 4.3 JWR66V).
Thank you!
Another quick confirmation; just tested with a nexus 10 under lollipop (LRX21P) and works as expected
What are the chances that this device will get TWRP and Root?
Not that I know... But this seems to be the best android tablet around now considering the price. Furthermore, its born with Android 8, which means it will be treple enabled thus the adaption of vanilla Android or others should be easier. Likewise, this should also improve security patches. I hope that someone will bring it.
Any progress of Rooting the HUAWEI MediaPad M5?
I want to buy it cuz my old Pixel C is sadly broken, but I wanna wait till it gots Root and Custom ROM:
@Marcopoloy13 I am in a similar situation as I would like to retire my old Nexus 7 (2012) and I am quite optimistic that TWRP will be available quite soon, as there is a device tree for the Honor 9 available and the Mediapad M5 sports the same SoC ...
As I am receiving my Huawei Mediapad M5 PRO next week, I wanted to look for root ... Is Huawei known to make a fuzz about root in case of sending it in for repairs etc. (I have a Samsung-past, friends of mine had issues with their support due to root ... ) ?
I am very new to Rooting, i just want to get linux deploy on this tab to install Debian. I have unlocked the bootloader the rooting is very hard.... i have no clue to what i am doing and was following the guide on this awesome forum but the imaging and so forth is not somthing i understand.
i have the CMR-w09 (non pro)
Unlock the bootloader?
How did you unlock the bootloader? I tried the “Huawei unlocking page" mentioned at Kingoapps website, but it didn't find anything about unlocking or bootloaders.

For any WIFI only device, contact Huwaei via Phone (they rarely answer mails, so dont write one), explain the problem using their site (WIFI only device, therefore no IMEI etc), provide them your tablets serial number and let them send the unlock code via mail to you. Takes usually two business days until you have the unlock code.
I have a Samsung Tab S SM-T807R4 that I’d like to install a custom ROM to. I’ve used ODIN and rooted the tablet. I just need to find out what version of TWRP will work on it and most importantly, a custom ROM. I’ve done a lot of digging and I know there aren’t very many of these devices in the wild so there’s not much support for it. Is there a version of Lineage OS that will run on it? If not, are there any alternatives? I’ve got that annoying screen freezing problem and I don’t really want to go back to lollipop.

I don't have this device myself but, the following area of the forum is specific to your device and variants.
https://forum.xda-developers.com/galaxy-tab-s
From what I've found, the SM-T807R4 has a Snapdragon processor and the Bootloader for all the Tab S devices with those processors cannot be unlocked (so far).
Thus you cannot install a Custom Recovery resulting in the inability to install a Custom Firmware (ie. LineageOS).
At the moment, the Bootloader can be unlocked ONLY for the Tab S devices with an "Exynos" processor.
Sorry for the bad news...
I do wish you the best of luck!

again, assuming you have a usa model (buying from samsung doesnt answer that question unless you say you bought a usa model from samsung meaning its a U1 model) then your bl cant be unlocked without paid service and you will not have oem unlock toggle at all
I said yes, can you recommend someone? Or where I can find them?

most of those are for international devices that are unlockable where there is a 7 day wait period and doesnt apply to usa models at all.. usa models are NOT unlockable.. that site even thinks you can create a factory/combination firmware by using stock firmware which is also bs lol

I Participated myself to this long discussion in this thread and the conclusion is that : IT DOES NOT WORK for the Galaxy A52S 5G !!!

Arobase40 said:
At present time we are all on the same boat for the A52S 5G USA or International models as this phone is not really unlockable even when the system pretends it is unlocked !
My OEM toggle is ON and when I turn my phone on I got a message telling me exactly this :
"This Phone's bootloader is unlocked and the software integrity can't be verified. Any data on this phone may be vulnerable to attackers. Don't store any important or sensitive information on this phone.".
But whenever I try to flash a patched AP file with Magisk my phone goes into a bootloop !!!
I tried different methods including creating a "custom ROM" with modified AP and BL files and the result is just the same : bootloop !
For what I know there is something related with the Samsung Vault Keeper mechanism and I'm trying to find out a workaround for this, with no result ATM...
So the purpose of my previous link was to fix the missing OEM toggle button, nothing else... But I guess this option may also be not available anymore with this phone... At least you can try...
On my side, whether I unlock or re-lock the bootloader (in Download mode) the OEM toggle button is always on... ^^
So I guess the unique solution should be to create a petition address to Samsung to put the pressure on this dam*** company ! ^^
I used to love Samsung products but this company's policy is driving me nuts and it makes me more angry as time goes by...

I am not sure what that has anything to do with the OP or this thread. Your bootloader is clearly unlocked. Because you dont know how to root it doesnt mean your bootloader is locked as well as doesnt help the OP at all since his model is a usa model and cant unlock the BL like you can.
You will likely confuse people by trying to hijack the thread to solve your own issues that are unrelated to this thread. Just saying.

both of those are unlockable and rootable but the op in this thread has a A526U or A526U1 so you both are in the wrong thread lol none of that will work on his device and sibce hes not unlocked and cant unlock in the first place he cant flash any custom firmware at all.
What is the KG or RMM state after you unlocked it? So to be clear, you unlocked the phone, booted into download mode, flashed the pached boot file, rebooted phone, it does not work?
So I'm coming to a conclusion that this phone is unlockable. Right? Right! Oh well thanks everyone for your help and support. Much appreciated.
Arobase40 said:
You're right on one point is that my post has nothing to do with OP but it was just a response to your own post... ^^
I'm here on XDA over 10 years and I always rooted my devices and I also saw different US Samsung devices being unlocked after a certain time...
So it's not a matter of hijacking the thread to solve my own issues but just a conversation to explain the situation of both A52 5G and A52S 5G whether from USA or International model...
Click to expand...

a response to my own post saying the links provided likely only applied to international variants and NOT to the usa models and therefore are irrelevant doesnt mean its ok to confuse ppl and hijack a thread to try and solve your own problem lol..
It is hijacking because the international models and the usa models are very different when it comes to unlocking the bootloader.. USA models cannot unlock the BL whereas Intl' models can.. you can unlock your bl but dont know how to root it which is completely dif. than the ops issue who cant even unlock the BL.. the "situations" you are trying to explain are completely different.

Well I'm not really wrong as I simply tried to solve the OP missing OEM Toggle !

you are wrong bcuz u are going based off all the intl models being same as usa models which they are not so any solutions you have based on intl models will not work as they dont apply to usa models.
Arobase40 said:
I don't understand why you are globally locked down with the US models and what you are saying is false and you know it as you are also the same moderator in the Galaxy Note 9 thread !
It took more time to unlock and to root the US Note 9 than the International one but at least it is now possible to unlock the US bootloader and to root the US Galaxy Note 9, including installing TWRP (since 2018) and some custom roms. You also proposed a way to root the US Note 9 without the need to unlock the bootloader and to touch the Knox flag. Partially useful but the problem is that you cannot do TWRP backup and restore when something is wrong... This was the same problem with my Galaxy Note 3 and with every firmware updates I had to redo the whole process from start to root it as there was no TWRP available at that time...
There may be also some other US Samsung devices in the same position such as Galaxy S10e (SM-G970U) but I don't own them and I don't have time to check all their situations...
I saw also TWRP for the US S21 Ultra and the US Galaxy Tab S7 Plus... based on your signature...
BTW, the OP issue is that he can't even try to unlock the bootloader simply because he can't see and can't access the OEM Toogle !

- USA Models have almost always been locked down. A few variants were unlockable for a bit like tmo or sprint but for the most part for years and years us models havent been unlockable without exploits and even then a majority of said exploits were just for root (bootloader was still locked and not able to use TWRP.)
- Not sure what you mean about Note 9 because I dont moderate in Samsung forums, I mostly am mod for Xiaomi. If you mean my root exploit for N9, that is using exploits and only for root, not for unlocking the BL.
- There was no way to unlock the bootloader of the US Note 9 in 2018. I posted the worlds first and only Note 9 root exploit which BL was still locked at that time and no option to unlock and use TWRP so I am not sure what you are referring to there.
- As I stated earlier I believe, devices released in 2019 to current (S9 to S21 and even some flip/fold devices) up to a certain update (each device is dif. but newer security isnt possible) via paid service which I also provide (and one other person) that relies on a device specific "token" that unlocks the bootloader. Even then, the oem toggle is never visible even after unlocking via paif service if it can even be unlocked (meaning its not updated to the point it cant unlock anymore.)
- My S21U did have an unlocked BL until I was robbed at gunppint and thethief broke my screen and upon getting it repaired theyhad to update it to latest firmware therefore losing my unlock. And the Tab S7+ that I have isnt a us carrier model (which are not unlockable without paid service) and is a SM-T970 (wifi only model) which is BL unlockable out of the box unlike us carrier models.
- Lastly, that is exactly what I am saying. He has a USA model that is not unlockable without paid service (if hes not updated to a firmware it no longer would work on.) The oem toggle will never appear. Theres no 7 day trick or anything he can do to get it unlocked. He'd have to find some sort of exploit that no one in the world has found yet or that they havent released (if someone did find some exploits.)
This is coming from someone who knows many devs around the world and as of last few years seems to be the only one still actively searching for exploits (and even found some root exploits and other things) and that only buys US models that are locked down tight and currently working with s21u a50 a32 5g s20u with no luck even at a root exploit. I was simply just trying to put it out there so ppl dont waste their time and stated the links and such ppl posted are irrelevant in this case as they dont apply to us models but hey, you can think I am wrong if you like and I hope op finds a miracle somehow to unlock his BL as itd help me unlock my other devices and others in the same boat but I'll take that with a grain of salt lol.
Hopefully this cleats things up for you.

Because this isnt your thread and the ops issue is completely different than your issue and US or intl model DOES matter because you are unlocked.. US model cant even get that far.. your issue is with not knowing how to root after your bl is unlocked.. ops issue ishe has a US model and cant unlock the bootloader at all.. talking about your issue confuses people with US models into thinking they can unlock their bl but they cant so two different issues...
Arobase40 said:
First of all I have to say English is not my native language so I can say things that can be misunderstood, but since now I don't think this is the case...
I never said or meant that US and International Samsung phone are the same or could be treated the same way nor did I said that ALL US phones could be unlocked, but as you said yourself : "A few variants were unlockable for a bit like tmo or sprint but for the most part for years and years us models havent been unlockable without exploits and even then a majority of said exploits were just for root (bootloader was still locked and not able to use TWRP.)"... ^^

Finally, you admitted you owned a "My S21U did have an unlocked BL"... So what should we think about your own words ???
In regard with my own International A528B phone I did the unlocked process and tried many times to install a custom AP file with Magisk but it didn't work as my phone enter into a bootloop process after flashing it via PC Odin. At last resort I relocked my phone and I was surprised to receive an OTA update which should be impossible if my phone was really unlocked !!! ^^
How can you explain this ??? lol

- My "pseudo" as you call it is a tag/status. I was a "recognized developer" before I became a forum moderator and before jpining the dev commitee. It is tags that every forum moderator receives so ppl can see who the mods are. I am still a developer. The way it is broken down is each device has its own set of moderators which you can usually find a list in each section usually its stickied forwhichever moderators can moderate that section i.e. I can moderate xiaomi forums but since I am not a mod for Samsung I cant moderate in Samsung forums. Rule of thumb though, if you see I have created a thread in say Samsung forum then that is me posting something I have developed or am developing i.e. N9 root method and obviously posting as a developer. You would know if I was posting as a moderator as it'd be saying something in regards to moderation i.e. cleaning a thread for bad language or off topic banter of which I would have deleted/removed comments or some sort of action or if responding to a reported post etc. etc. So it would be clear if I was posting as a moderator as I would make it clear.
- The snapdragon dev section in N9 forum is for all snapdragon models of the note 9. The N9600 is the Korean variant if I am not mistaken and is unlockable by default. The OP in this thread has a USA variant, I did not say all "snapdragon" models were the same. ai simply stated "US/Carrier Models" were not unlockable without a paid service. Since N9600 is not a US/Carrier model it is unlockable and is in that section because it has a Snapdragon chip in it therefore falls in the category of an international model that is unlockable by default and therefore unrelated to the discussion here. The korean variants typically end with a 0. Models that are not unlockable are typically ending with U, U1, or W i.e. N960U, N960U1 or N960W. Anything else is likely not a US/Can model and are typically unlockable by default.
- Afaneh is the other person that can unlock bl's using a paid service which I already stated. USA models can use twrp once they get paid service (given they arent updated to a firmware not able to be unlocked) to unlock the bootloader first. This is the ONLY way to unlock the bootloader. He also makes twrp builds for devices and clearly (as you also included in your link) he is clear that you need to use a paid service. As for that other twrp post I have no idea. Because someone posts in a Snapdragon section and isn't specific on which variants it is for is not against any specific rules. I can bet however without even looking at it you can likely read the comments and see people with US models saying it didnt work or asking how to unlock the BL because it wasnt possible. Typically in those threads the dev will indicate you need to unlock the bootloader first and US variants cannot unlock the BL therefore that TWRP wouldnt apply to them at all.
- As far as your issue, the fact that you could successfully flash custom firmware using ODIN tells me you were unlocked. On locked devices (i.e. US variants) ODIN would fail and device will say an error so they wouldnt even be able to get that far. Samsung always likes to be different in how android and root and stuff work. Sometimes magisk needs to be modified or tweaked to work and sometimes the install instructions vary by device. I cant help you there because I sold my N9 before was able to unlock the bootloader but can guarantee you are able to root your device since bl is unlocked you just have to find the right instructions and follow them to the T. I do not know the steps for your intl model so I cannot say why its bootlooping but I assume you are missing a step somewhere.
As for relocking and getting an OTA, it is possible even if you were still unlocked. OTA will not work however if anything is modified i.e. if you are rooted the ota will fail. Simply having an unlocked BL you can still get an OTA if you havent modified anything i.e. no twrp and no root and no modified rom etc.

First of all, when I posted a thread with a link on how to unhide the OEM toggle I said "Maybe you can try something like this ?" and nothing in the link mentions it was an International model !
And at present time nobody can certify my A528B phone is really unlocked as I was able to relocked it and I also received an OTA update which would be impossible if my phone was really unlocked !!!
That's why I said we are on the same boat... at present time... ^^
In regard with US bootloaders I gave demonstration it was possible to unlock some of them with different Samsung phones and I never said it was possible with all of them but sooner or later it is possible to unlock some of them whatever the process with or without paid services...
Ok, I'm now done with this discussion.

I said it was irrelevant because it will not work as usa models cannot unlock the BL. A lot of those sites will not list specific models and assume every model is the same andsometimes even use old pictures/instructions for super old devices and just create new pages. I bet most samsung sites like that all have same instructions word for word and only difference is the name of the device lol. I dont know why they do this but they obviously dont know what they are talking about,dont care or the page creation is somewhat automated but rule of thumb is us models cant unlock so you can assume those pages do not apply to us models.
Again, you can get an ota if unlocked and on complete stock firmware hence doesnt mean anything really. To add, just the fact alone you can toggle oem unlock and unlock your bootloader and were able to successfully flash a modified firmware in odin says you were unlocked as it would have failed in odin and not flashed anything. The fact that you bootlooped aftereards doesnt mean you werent unlocked, just means theres some steps you are missing or the files you used were no good. This also means you are NOT having the same issues. I dont know why its hard for you to understand that op cannot unlock his bl at all, doesnt even see the oem toggle (and never will) is the same as you who can see the oem toggle and can unlock bl and can flash modified firmware but bootloops afterwards as being the same issues.. OP can only hope his device isnt updated and can pay for paid service to unlock whereas you need to find proper instructions on rooting your device and to avoid a bootloop.. two completely separate issues.. You might have initially thought they were the same issue but that is why i clarified multiple times they are not the same issue at all and you even have a completely dif. variant than op does.. If you still think they are the same issue then i dont know what to tell you at that point and hopefully op realizes that he can only unlock with paid service and isnt confused as you are.
And yes, some us models were unlockable years ago.. In fact, I believe the S4 verizon models could unlock using an exploit on a certain firmware and verizon note 4 could unlock using an exploit turning it into a dev device but outside of that it has not been possible so if you are saying some could be unlocked going based off devices that came out years and years ago then sure. Recent years/devices though it has not been possible.
The paid service technically uses an exploit that creates a "token" that sets device to allow custom firmware to be flashed (essentially acts like an unlocked bootloader) but isnt unlocking the bootloader in a traditional sense at all so one could argue it isnt exactly the same (although result is the same.)
I just wanted to ask if there is any development effort going to bring TWRP and AOSP Custom ROMs to this device.
Under the hood, this device is very powerful. And well built. After using it for a few days, I feel like the just software experience is holding it back.
If there is, I'd like to join and help as much as I can.

Tbh, the stock rom (global) is sufficient, and with root you can modify it however you like...
Custom development may start after Realme stops supporting the phone with OTA updates, which isn't anytime soon since GT 2 Pro is their flagship...
There is also Android 13 coming out...
And until there is an open-source bypass of MSM tool to recover bricks without paying $$, I think that not many people will waste time and money to build custom ROM and then maintain it to integrate Realme OTA's.

What about Xiaomi? They also have auth for EDL flash. But if you see the forum for xiaomi devices. It got lots of Custom ROM.
There's no need for a free MSM. To install any custom ROM you would have to unlock the bootloader first, and with an unlocked bootloader you can recovery every brick, unless you destroy the bootloader itself.

Yeah tell me about it.....I still feel violated for having a random stranger connect to my computer just to type a damn password, and paid for it....never had this issue with xiaomi, mi flash tool works great.....we need to pressure realme to stop this insanity.....there is no reason for having MSM locked.

I also agree with this. And the unlock process itself is crappy. We need to install a dedicated app to be able to boot into fastboot mode! Why? Why not just allow bootloader to be unlocked like OnePlus devices, both phones are from the same parent.
