Unlocking A505U Bootloader with ADB - Samsung Galaxy A50 Questions & Answers

I have an A50(A505U through Sprint) with a locked bootloader. I've tried the 7 day trick to enable Oem Unlock in Developer Options but it doesn't work. I'm wondering what the chances of being able to to force oem unlock using adb is without bricking my device? I figure this is to easy of a solution but hoping someone is willing to try it!

I also have the same Sprint A505U and I'm having the same problem. Hope we get a resolution for this.

im picking up a verizon A505U tomorrow.. out of curiosity, are you able to flash combo firmware?
also to add, you cant force oem unlock using adb.. you can probably set the oem unlock to on in adb but it doesnt actually change the unlock bit wherever its stored in the firmware so as soon as you reboot its back to 0.
If you can flash combo however you can enable oem unlock then flashing back to stock the oem unlock bit should remain on.
Either way, I will be playing with it all weekend lol.. i just hope its not like the A102U i purchased from tmo which doesmt let me flash anything

Yes I have used Odin to flash a sprint firmware from samfrew and and found out it was sprint verzion firmware when poking around.
I suspect it is going to be the same. All U variants can't be unlocked from what I've been told.

Nope. I got in to download mode and flashed the sprint firmware from samfrew and it works fine. I discovered the firmware has some vzw apps included but not all of typical vzw bloat.

i can install stock firmware fine whether its sprint or not..
what im wanting to flash that i cant so far is the A505U Factory Combination firmware, not the stock based firmware.
Factory combo firmware usually cant flash and will say it needs approval to flash factory binary..

I take it it's currently impossible to unlock the bootloader on the SM-A505U?
I haven't done much with Android since I had a spat of amnesia so I don't remember much, but is it possible to root this phone without unlocking the bootloader? I don't have any plans of installing a custom ROM, just want root privileges.

Witam! I znalazł ktoś jakiś sposób na odblokowanie? Zależy mi bardzo na TWRP oraz Root.

Was anyone able to flash a combination AP file? I get a secure check fail for everything. I'm using Heimdall. Whichever packet is uploaded first, it will fail at that packet.
Edit: Just realized it's probably because of RMM state. Has anyone discovered a bypass? I guess I'll try waiting for 7 days with no sim card and see if that does it. Tried Chimera tool to RMM Unlock with no luck

Following along this thread. This is my first post ever. I have some experience with odin and Samsung. I would like to try out flashing and return with the results. Not afraid to soft brick. Could I possibly get a link to anything you have so far and I will share anything I find? Thank you.

[Q] sony noob. feel stupid...

ok guys i just picked up a play for att. sucks cause i have tmobile and wont get the 3/4g data. im almost always in wifi spots anyway so no big deal.
anyway i have already called att and got the phone sim unlocked. now if i think i understand this correctly this should be the order to follow. if you guys can confirm and provide latest links i would appreciate greatly.

2. unlock bootloader (not yet)
3. root (not yet)
4. load rom (not yet)
correct??? did i miss anything? any preferred method on any of these? please advise.
thanks!!!
First of all, if you bought a xperia PLAY, you should probably post in the xperia PLAY forums.
Second of all, questions go in the Q & A forum.
To answer your question, that's pretty much the right order.

For img flash you can use flashtool.
You don't need root or anything to use flashtool on your phone.
Just pick correct .ftf for your phone and flash it to the phone.

If you were rooted before you don't need to re-root unless you purposely unrooted it. IF you aren't rooted anymore superoneclick or the zergrush(however it's spelled) is the easiest. I'm 99% sure you don't have an unlocked bootloader though, so you have very few options. I'd say re-root if you need to and unlock your bootloader so you can flash flash and flash custom roms like crazy

It got bricked because you didn't unlock your bootloader.
1.Root your phone
2.Install Recovery
3.Unlock Bootloader
4.FINALLY!! you install a rom okay?

You need to pay Setool credits in order to unlock the bootloader. Unlocking the bootloader allows you to lose the sin lock as well, so you could have killed two birds with the same stone.

ya i just found the website. seems like thats the one everyone is sent to on this site.
im wondering now that im rooted if i can clean this stock rom up enough to use on a daily basis. i mean im using tmobile on the device so sharing internet would only be edge lol. i guess the only thing i really want ics for is that fact that its ics.
open the dial pad and use this code*#*#7378423#*#* . Then go to -> "Service Info" -> "Configuration".
If it says unlock bootloader = no, then you have to use the paid service, if yes, then you can do it for free yourself.

[Q] Upgrading an Unlocked AT&T Samsung Galaxy SIII

I sincerely apologize if this has been asked before. However, after lots of searching, I have been unable to find an answer anywhere.
I am more experienced with iDevices as opposed to Android. With Apple products, as long as the device is not factory unlocked, every time the firmware is flashed, the unlock process will need to be redone.
So, I have an AT&T Samsung Galaxy S3 which is unlocked via an unlock code, and I use it in the Caribbean. I'd like to update to the latest firmware (4.0.4 > 4.1.1) using Samsung Kies, on my desktop. Before I do so, I'd like to know will the phone remain unlocked after flashing the new firmware? Or will I need to unlock once again?
I apologize if this is a stupid question, but I'd just like to be precautious. Thanks for any help in advance.
P.S. My device is rooted. Will this affect the update?
I don't think the update will effect the unblocking....
But why update thru kies when the stock/rooted rooms are found here too??
Kies will have issues updating if your device is rooted.... So just flash the stock rooted images, via Odin program, here on XDA.
Here are the stock/rooted 4.1.1 ROMs with Odin program as well:

Thanks a lot guys. Appreciate the answers.
Sorry for the double post. However, just updating that I just successfully updated to a fresh install of 4.1.1 from 4.0.4, and my unlock is indeed still intact. So, anyone else who is a n00b like myself, and is worried of the same thing when updating, don't be.
Hello. I am new to samsung. It came from At&t and i unlocked it here in the philippines. And as ive checked the software it is still 4.0 and since i want to update the software it only says communication failed. May i ask if is it possible to update my s3 to the latest version? Im really desperate Thank yooooou.
A phone can be relocked once an unlock code has been entered but this only happens if the phone undergoes a repair and the IMEI is changed.
Also, just to calrify as the original responder has mentioned "blocking". A blocked phone is very different to one that is locked. This might confuse people but just to confirm, if you have a blocked phone, unlocking it won't help. A block is done at network level and stops the phone connecting to any network to make or receive a phone call. A lock is at phone level and simply limits the phone to working on one network only. A lock can be switched from on to off to allow it to work on all networks but a block can only be removed by the networks.

If your phone came with 4.3 already installed from T-Mobile or you took the official ota then you are out of luck as far as downgrading is concerned. Are yu any of tthose? if so, you will have to buy an unlock code from an online unlocker like FastGSM

[SM-T837V][Combo Firmware and Stock Firmware Files]

Hello Folks!
As soon as I got the tablet I spent a good few hours looking around for the combo firmware to start looking for exploits so figured I would provide you guys with a link to the firmware for free
It was quite funny actually, after I soft bricked and got stuck in a boot loop I realized I couldn't find any stock firmware anywhere either haha, so I spent a few hours looking for that as well.
I have the Verizon variant, I am not sure if it will work on other USA variants or not as I have no way of trying. With that being said, below will be the links. I will provide a rev1 combination firmware and a rev1 stock firmware as well as a link to a modified ODIN for easy flashing!
And with all that being said, the combo firm is good to bypass FRP. You can enable the oem unlock switch but other than removing FRP it is useless as of right now. You can however, mix and match the firmware unlike my S9+. I am currently on stock firmware with a permissive boot.img for example.
If you got questions or need help, well, you probably shouldn't be downloading anything or flashing haha. But I will try to help when I have time. I do not have any current plans to keep this thread going with updated filese as I had to pay for these. If I can find em free moving forward I will re-upload if I can but I typically stay on the lowest rev/firmware I can until I find a root method
T837VVRU1ARG4 COMBINATION FIRMWARE/FACTORY BINARY
T837VVRU1ARGG STOCK FIRMWARE
MODDED ODIN v3.13.1
If you feel like buying me a beer...​
What is the main benefit of this?
In the q&a section someone wrote it is readily rootable with Magisk. Is that not the case?
@elliwigy
Is there any firmware for the unlocked LTE snapdragon. I got the Verizon version but it's not playing nice with AT&T. Any ideas? Maybe flashing the unlocked firmware would help.

I think it's just the tablet, my Verizon one isn't playing nice with my Verizon service. Constantly not switch towers and losing service when full service is available. Or it's a tower problem but my note8 doesn't do it when my tablet does
Thanks for this, have been looking for a couple days for the build.prop file.

OEM Unlock
I have the T837V and would like to ODIN flash your files, but as you know there is no OEM unlock in the Developer Options on this tablet. Are you saying that you can flash these files without enabling the OEM unlocking?
I would like to install TWRP, but I believe this is not possible without enabling the OEM unlock. Do you know if this is true?
Thanks

Forgive my apparent noobishness but what exactly will that do? Looking for a way to root and wanna know if u have found something I haven't.
Flash firm then what? Does it make OEM show or what? I just happen ta have the most difficult version of the tab S4 which is SM-T837V

I am currently working on a root method with the N9 but it should also work on Tab S4 once all is said and done. I actually found the exploit I use on the Tab S4 originally before I started workin the N9. Nothing is released yet as so far have only gained root on S9 Exynos and I am currently super bricked and waiting for a device replacement lol
Flashing other carrier firmware won't help you unlock any bootloaders or anything nor will it necessarily help you root. Only benefit I can see really in flashing other carrier firmware is say if you have an sim unlocked tablet (we'll say it's a Verizon tablet) and you want to use it on say Sprint. You can flash the Sprint software in ODIN and everything should work. It would be like you purchased the tablet from Sprint essentially.

Hello Folks!
As soon as I got the tablet I spent a good few hours looking around for the combo firmware to start looking for exploits so figured I would provide you guys with a link to the firmware for free
It was quite funny actually, after I soft bricked and got stuck in a boot loop I realized I couldn't find any stock firmware anywhere either haha, so I spent a few hours looking for that as well.
I have the Verizon variant, I am not sure if it will work on other USA variants or not as I have no way of trying. With that being said, below will be the links. I will provide a rev1 combination firmware and a rev1 stock firmware as well as a link to a modified ODIN for easy flashing!
And with all that being said, the combo firm is good to bypass FRP. You can enable the oem unlock switch but other than removing FRP it is useless as of right now. You can however, mix and match the firmware unlike my S9+. I am currently on stock firmware with a permissive boot.img for example.
If you got questions or need help, well, you probably shouldn't be downloading anything or flashing haha. But I will try to help when I have time. I do not have any current plans to keep this thread going with updated filese as I had to pay for these. If I can find em free moving forward I will re-upload if I can but I typically stay on the lowest rev/firmware I can until I find a root method
I was wondering if i could flash firmware for my 837T for tobile to work on AT&T? I understand how to work odin etc, i just was not clear on the software variants and their capabilities.......
thanks

Hi. I have the metro pcs variant 10e. Our oem unlocking in developer options has been hidden/disabled/missing. Is the a10f the same as far as my metro variant? Also when trying to get into bootloader mode the phone vibrated and a little yellow exclamation ! symbol appeared at bottom of my screen right above the charging port. What was that exactly? This is my 1st A series device

even if its the same you cant unlock the bl or root as its a usa variant and its not allowed.
the yellow symbol you see is normal.. its an indicator for the charging i believe to indicate slow charging for example

you do know flashing combo firmware now requires factory approval in the form of a token right?

I don't really follow Samsung much anymore, when this was posted the phone was new and I had access to both and both firmwares weren't available anywhere so I posted it in case it would help someone.

I have metro ASK4 firmware currently on phone. I found official ASK1 4 file firmware . When trying to downgrade I get SHA256 error. So locked bootloader prevents it? Cant even downgrade. What can I look into as far as changing property values sys.oem_unlock_allowed 1 temporarily if anything? I do apologize if my questions annoy the more experienced members. I used adb shell setprop and it added it but theres 2. One with 0 and one with 1

That's because you spelled it wrong bro lol.. it also doesn't do anything unfortunately and reverts after you reboot the device.
You cannot downgrade.. most time even on unlocked bl's downgrading is not allowed.
If you mean you found a lower firmware on same rev that's a different story. You get sha error because you need a modified odin that has the sha checks disabled.. or you can use something like chimera tool
timba123 said:
Lol I see my spelling error now. I think I was really burned out trying to learn and figure out stuff. Is there any decent links on how to patch SHA256? I tried many web searches and little results

huh? thats not useful at all lol.. theres already pstched odins all over the internet.. it doesnt patch the firmware, it patches odin software so it ignores the sha256 altogether
timba123 said:
Yes there are many patched Odin's but not a patched 3.14 version. My device will not work with any odin lower than 3.14

i forgot lol.. i also have an a10e but i use chimera tool and it works fine and no sha checks if u select that ootion

Unfortunately I cant afford any tool like that. I've tried crack versions that dont require box or card but none of them are current cracks.

Thanks. I downloaded official version. Pay day I'm going to try a starter license. I'm a little excited lol. Do you know if it flashes combo on a10e?

it does/doesnrt.. u cant just flash combo firm to the device, it also has nothing to do with odin or chimera.. samsung implemented security so combo firm cannot b flashed unless you have a token for it.. without it u can only flash stock firmware.. if u got acombo token tho then yes, chimera at that point could flash combo no problem
