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.

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.

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.

You could use odin to get to OF1. You could use Samsung Smartswitch. You could go to sammobile too.
You will lose the ability to root your phone if you take this update.
Here is the odin file.

The files for all variants are available from sammobile,

Personally I have never visited the website,
but a quick Google search seems to confirm it.
Hello Community!!
I have owned many androids over the years, and have recently got an S6, hoping to dive back into the game of rooting, modding and messing around until my phones works the way i want it to. There are MANY things that really Piss me off about my T-MObile variant of the S6, including the horrible battery life, bloatware, and lack of personality. I Really would love to root my device, but KNOX. OMG what is this?! If i Root, no Samsung pay? What other downsides are there to rooting? But recently, my phone installed "ANdroid Pay" SO I am thinking, I should just root, forget Samsung pay and just use Google pay or whatever they call it.
As you guys can tell from my sig, I have been very inactive on these forums. I am hoping someone can give me some advice here---
Thanks So much

There are pros and cons to root.
The first pro is limitless customizations and personalizations.
The first con is OTA updates get disabled.
Another pro is you are able to dramatically improve battery and overall performance using various apps.
Another con is your warranty will be void, assuming you tripped KNOX.
If you trip KNOX, Samsung Pay no longer works; if you have root (even without touching KNOX) Android Pay does not work.
I obtained root just to prove to myself it could be done.
Since then there have been dramatic improvements with speed and battery life.
Package Disabler Pro can freeze a lot of the bloatware without root: https://play.google.com/store/apps/details?id=com.ospolice.packagedisablerpro&hl=en
Hi,
It's a highly personal decision. I myself for the first time am holding on rooting - I was the one who made the most famous Xoom rooting tool and also S4 Linux Root Script, so that tells a lot. The thing is, meanwhile my device is satisfying my needs, and I'm really curious about Samsung Pay, as it has a way wider support than Android Pay and other systems.
The best thing about rooting in my opinion was the endless system customization - specially after Xposed was released. The way better data management I had, better system control and some exclusive apps that require root or works better with root. If you are really pissed about Samsung TouchWiz apps and system "features", rooting would be a nice idea. Just keep in mind that after rooting Knox will be tripped and there's no turning back with Knox. Depending on your country, Knox trip also means warranty void, because once rooted you can unroot and make it looks like nothing happened.
Just adding what was already said, but Android Pay doesn't work with root.
All the best,
~Lord

Rooting doesn't allways mean tripped knox. I have my G920F rooted and knox intact. This can be done even after updrade to 5.1.1 stok firmware.
An android phone for me is worthless without root permissions. I need it for:
adaway adds
iptables (firewall)
better battery life (debloat)
titanium backup

I was only aware of root that can be applied before upgrade to 5.1.1.
Can you advise how you applied root after 5.1.1? Thanks.

Just install de 5.0.2 engineering bootloader via ODIN. Then instal TRWP via ODIN.
After this two steps you can flash whatever you want via TRWP.
Edit: with the 5.0.2 bootloader you will loose fingerprint scanner, the rest works great, at least with the custom rom I am using.

Keep in mind this engineering bootloader does not work with all variants. For example there is no Eng Bootloader for the Canadian phones.
Thank you both. I have the international SM-G920F (technically it's the dual Sim version, SM-G920FD, (from United Arab Emirates)).
So, to confirm, would the eng boot loader still work on my device variant, and allow root without tripping KNOX?

I have the single sim version of the G920F, so I don't know if it will work with the dual sim.
I don't think that it will strip you knox...
... and I think that if your phone doesn't work with this bootloader, you can just flash the correct one and make it work again.
But these are just guesses... you decide if you want to take the risk.
Good luck.

Hi,
I wouldn't risk that "you can just flash the correct one and make it work again". If you know how a bootloader work, if it gets broken there is no way to get to Download Mode and flash a new firmware/bootloader.
For information sake, a bootloader is a piece of software that is the first thing loaded when you boot your device, it comes before anything, be it kernel, be it recovery or anything else, that means, if you have a broken bootloader, the moment you try to boot your device up, it will try loading BL and it will fail, so it will shut down back again. I've had a broken BL once before on S4, the only way to recover was a direct flash of software in system chip using a tool called JTAG.
So, all I can say to users who still didn't get it: beware with this. It seems that many people are getting successful results, but it's an extremely risk procedure, make sure you read every single instruction and follow it, the possibility of a hard brick is high.
Even still, it's a great find, thanks for sharing with me, I didn't know of this until early today .
All the best,
~Lord

Did you mean, once rooted we can unroot and install the stock firmware and hence tripped Knox will be restored as well?
Or the unrooting will only help to restore the stock but the knox will continue to remain tripped. I would like to know this as I am considering purchasing S6. The last samsung phone I owned was S2 and used that for 3 full years with out any problems.
Thanks.

Once Knox is tripped its tripped but, yes you can flash original firmware and as long as you factory reset it, it will be unrooted and ready for official updates.

Once tripped there is no going back. Voided warranty depends on laws of your country and your retailers policy.

YOU CAN NOT UNTRIP KNOX, you can reflash your firmware from Sammobile, http://www.sammobile.com/firmwares/database/SM-G920F/
use odin and then after you flash, go into recovery or use system settings and conduct a factory reset. It will say Official in the status but, since they will reflash your rom anyways, they will see the knox trip.
It depends on where you purschased your device whether or not they will warranty it with Knox tripped.
Honestly, anyone who roots should understand this information before hand. You should always know how to return to stock unroot.

After rooting my 5.1.1 without tripping Knox, with the 5.0.2 engineering bootloader (as as described a few posts ago) I have flashed a stok rom with odin and then everything went back as it was before the rooting procedure.
1. I was on stok oficial rom with oficial bootloader.
2. I lost root.
3. Knox was still intact: 0.
4. Fingerprint scanner and MyKnox worked again.
So: after upgrade to 5.1.1, rooting with the 5.0.2 engineering bootloader seems to be safe and also easy to bo back to stock... at least for my model (G920F)
I have a stock N915T purchased about a year ago, it is still on 4.4.4, as I was not going to update to 5.0.1 due to Samsung's own problems. The phone is currently used on the Rogers' network in Canada. My question is can I use ODIN to flash the N915W8 5.1.1 Rogers firmware to my N915T without experiencing any problems? Also would this upgrade replace the Canadian radio on the phone, or would I have to manually flash the radio file?
Thanks in advance.
I would just root what you've got and go from there.

However, from my past experiences with Note 2 and S3, flashing with ODIN would unroot the device, essentially bringing the device back to stock.
Wouldn't that be the same case here? ie if I rooted my edge, then flash the w8 firmware, wouldn't that be the same as the method I proposed in my OP?

Okay so my device is Galaxy S7 and I had it rooted and running LineageOS for a few days. Because of security, I decided to install stock firmware using Odin. This runs well as stock. Play store and phone info sata this is certified and official software. SafetyNet gets everything passed and says no root. But still my Samsung apps cant run, since they think this is rooted... What to do? Can there be some files left?

After rooting your phone warranty will be set to 1.
You can check by going to download mode and reading the property : Warranty void
If its a 1 you can never use these apps again for security reasons

This isn't correct, once you flash back to stock with Odin the security is restored. The knox counter trip means the warranty is void because the phone had been rooted etc
