[Q] Is any .apk or method is avilable to unlock bootloader of samsung galaxy S5

Hi,
I am using samsung galaxy S5 SM-G900R7, i am able to root this phone then started trying flashing of custom boot.img contating custom zImage. ODIN is showing successful flashing , but when i am restarting its always going in download mode with error message "couldn't do normal boot" . In download mode there is a line "QUALOCM SECUREBOOT : ENABLE". I doubt this is beacuse of locked bootloader.
I want to know is it really beacuse of locked bootloader?
I downloaded kernel for my phone model from samsung official website mentioned below and built in same way they have given instruction, so i ahve less doubt on custom zImage.
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=900r7
if yes then i have second question is it unlockable or not, i am not getting any unlocking method for samsung galaxy S5. whatever info i am getting regarding unlocking is upto galaxy S3 but not helpful for galaxy S5. PLease help me to come to a final conclusion on flashing custom zImage to phone.

As far as I'm aware most Samsung devices if not all have unlocked bootloaders, as for a soloution I haven't seen anything really but some say you need to re-flash stock then try from scrath or make a backup after reflashing stock and a custom recovery then format and restore to get it working.

Thanks a lot for your reply,
I searched regarding this and i found latest samsungs are coming with KNOX security in which SECUREBOOT is there, which doesn't allow phone to boot with any boot image if chacksum value doesn't match. so i feel even if bootloader is not locked here but same thng KNOX security is doing. Help me if you have any idea how to disable it in samsung galaxy S5. Getting way how to disable in previous series but not finding method how to do for galaxy S5.

Looks like getting rid of KNOX is a difficult task but not impossible: http://www.s4miniarchive.com/2013/12/how-to-remove-knox-bootloader-from-new.html

I think your post brought me closer to soltution. Tommorw i have to try this. The only problem now i have that i am not getting firmware for my phone model SM-900R7, I am getting firmware for model number SM-900R6 which is very close to this not not exactly for SM-900R7. I have to search more to get it, i hope i will be able to find it.
Thanks again for your valuable post.

Hi,
Yesterday night you posted a link, that link was good but still my requirement is different.Yesterday i was not able to go through whole link you provided to me, today i was reading the whole article. its looks like they are trying to save warrany of phone even after flashing custom ROM. They are deleting bootloader contents of flashing ROM, even i will flash custom ROM with deleted bootloader contents, In phone bootloader will remain same with KNOX SECUREBOOT feature. My target is to flash with KNOX disabled bootloader so it will not stop booting with custom zImage.

Actaully that link was removing KNOX from firmware which you are going to flash not from phone if you have already KNOX is there. That is for if your mobile is not having KNOX and you dont want KNOX when you are going to flash with recent updated firmware so you can delete KNOX contents from firmware and can flash.

Hmm, it appears it not possible due to it having a locked bootloader/KNOX not being removable

Dm-Vertify Bootloop

Hello today i come to you with the dm-vertify bootloop issue. I got stuck in this dilemma by attempting to SIM unlock to be able to use my Sprint Variant on T-Mobile and my stupid self was messing with settings i should have resulting in this. After research i have found that i need to flash with Odin using the stock Firmware firmware but i cant seem to find the exact firmware i need to un-brick my phone.
In the system recovery it lists "LMY47X.G925PVPU3BOL1" as the version of firmware my phone is currently running on. If anyone could help me Locate the appropriate download that would be much appreciated!

You wouldn't mind sharing me your EFS, I went into deeper crap with an error saying device does not have drk please install drk first and the only way to bypass it is to root which I don't want to keep. Would really appreciate it if you could help me out :good:

Root for Verizon Prepaid Galaxy j7?

Hi,
I was wondering if there is a root method for the Samsung Galaxy j7 Verizon's 2017 edition (SM-J727VPP). Is it even possible? I read that the bootloader for verizon phones are locked so you can't root them. Is this correct?
Thanks.

I'm on the same boat. I love the phone but not sure how to root it. Anyone know if the other root methods work for this phone?

I just bought this phone as well. Anyone dedicated into developing an unlock method for the bootloader and custom recovery would greatly be appreciated.

I haven't tried on this one yet (scared) but with Verizon's bootloader I know that its pretty much permanently locked.
... at the very least for now,
Meaning, it MAY be possible to get root BUT that would b where the road ended... no custom roms.... etc.

Root better than nothing.

Maybe you can try the app in this video for Windows looks like it has a big list of various Samsung models
I tried the link in the video but it takes you to a 4shared link that seems kind of spammy so I searched for the file on Google and found it eventually about to try it on the PC right now..
Tried it its a jtag app that need a box to flash firmware
We need to find a 7.1 n root exploits that work or find a way to dump the firmware I can't find any restore firmwares online yet

I have the stock firmware for j727VPP, the QB2 bootloader version to be exact, which is stock. It's Odin flushable , if u need it for any reason restore or w.e let me know n send me an email @ [email protected] . Also, Verizon just came out with a update for j727vpp which changed the bootloader to QF3. Do not update, otherwise going back to QB2 will be near impossible and if anyone does come out with a root then it will be for the QB2, not EF3 bootloader. But, if u already did update and need the EF3 firmware for restore purposes I have that as well, except it is in a ENC4 format, which is a RAW format for firmware. U will need to decrypt it with 7Zip to Tar or Md5 in order to be able to flash it. Like i said email me - [email protected] and I'll provide u with whatever files u need.

Any root yet?
Is there a working root method available for this phone yet? There are a few websites that claim to be able to root it, but I don't want to take a chance and brick my phone. Thanks.

[HELP] Samsung S7 SM-G930W8 OEM

Hi everyone, I bought this samsung s7 sm-g930w8 phone and I tried to root the phone but was unsuccessful.
Now I can't enable OEM unlock. It's not grey out but it just unenable.
For some apps it said can't be opened on a rooted device. When I checked with rootchecker it said root access not properly installed.
I already tried to unroot and do a firmware reset but nothing change. Please help. Thanks

So that is a Canadian Exynos device yes?
First thing to try is to make sure your following any guides exactly and are using the correct version of any files. Then try rooting it again. I'm going to assume your using Odin in download mode and it doesn't give you any errors but a "pass" when complete.
Also I've always found it much much easier to install TWRP first then root.
If none of that works,download firmware,flash with Odin and use Home_csc so you don't lose your data.
It would be helpful if you provided your firmware version, cell carrier, locked to carrier? Etc

New easy way to root ALL Samsung devices 100%

Hello everyone
Here is new method to root all Samsung devices,twrp not needed.
First you need to download EFTSU tool: https://mega.nz/file/34lDEBqB#7mSv2SeYKP2kReheBk7q5AU582TZUdsJy6GL5sd7O-I
Then you need file from this website where you can find for your device and download it : https://eftsu.com/
After you downloaded this file put your samsung device in download mode *need oem unlock* then flash your file with eftsu tool.
Your device will reboot it and it will during boot ask to reset ,then reset it.
When it comes to system you need to download and install eftsu manager: https://mega.nz/file/Oo1yCSiQ#rWlMbcBiBHSzv5oMioyGxQZ0ynxqaeqz_Nfm4ze240c
And you are done.
You can also install root checker to see if it rooted.

Hello! I want to root my Samsung Galaxy A01 with firmware A015MUBS3ATL8, I found all the files that I should download, but no way to unlock the bootloader, I did all the guides and when it asks me for confirmation on the bootloader screen to unlock it, I affirm and the phone is formatted and it reboots, but when re-entering the bootloader it is still blocked
Sorry for my bad English, I'm using Google Translate

Please help.
My phone is SM-G955F with Exynos processor. Hungarian XEH code. The latest PIE is running on it. OEM does not allow unlocking. The slider can be turned on, but it also turns off immediately after enabling. What can I do to make OEM resolution work?
Thank you.

I have a samsung galaxy j4 +
I got it from a friend today.
The phone is after a hard reset (some dumbass did it)
Unfortunately, there is no access to google accounts because the accounts were from her husband and he died.
I keep searching and trying but can't root. Because Debug Usb doesn't go on.
And the computer doesn't read the phone after all.
Yes, I have drivers installed, various Odins, I also took your EFTSU, Fastboot and I do not read my phone anywhere. Nothing else is just loading.
Yup i trying Hard reset many many times...

try to frp unlock your phone,you have here on xda tuts how to do it,just search for it.

what do you mean nothing happened?

I can't unlock the OEM with either method.

did you follow the guide i wrote above?
First you need file downloaded from the website and with the eftsu tool flash it in download mode,the when phone is reseted and comes in system install eftsu manager and root checker and in root checker you have to see if it's rooted or not.
