[Q] How to unlock bootloader of samsung galaxy S5. - Galaxy S 5 Q&A, Help & Troubleshooting

Hi friends,
I am having samsung galaxy S5, i wan to install my compiled kernel in phone. my phone is rooted. I tried flashing boot.img updated with my compiled kernel, i was able to flash with ODIN but its not booting. After analyzing more i feel that some checksum checking is going at bootloder level. I tried many thing but i was not able to resolve this issue, Even after successful flashing with custom ROM also phone is not able to boot with my zImage. I have less doubt on kernel becasue i downloaded it from samsung website for my particular phone model and also compiled in same way mentioned in README file. In my phone "QUALCOM SECUREBOOT" is enabled and looks like its not allowing phone to boot with custom zImage.
Please tell me if there is any way to unlock bootloader of samsung galaxy S5.

What the hell is this?? Wrong section dude go read the rules before posting

I just attached a snap of a thread where a person who is also senior member in XDA developers suggested me to post my questions here, and i feel he is not less intelligent than you. Since i am new to this forum i felt right to take his suggestion and post my query here. Give a look to that attachment might be u will recognise that person.

Hi Yeroslav,
Seems like you're new to custom romming and rooting. There are roms here in the development forums with "HALO" in their topic header. These are the roms that you may want.
Rooting and romming has it's risks (soft bricking/ hard bricking etc.) and puts you at risk of various problems unless you know how to solve them when they arise ( bootloop. network errors) , so maybe you want to google it before you begin anything. (We're all doing it, so it's low risk, unless you do something majorly wrong like flashing a rom for a different phone model)
Also, when referring to forums here, you first need to check your GS4 model if it's I9505 or I9500, commonly found when you first boot your phone. Once you've obtained the model number do look in the relevant forums (Android development/original android development) for rooting and custom romming methods. (As mentioned before, flashing roms for a different model can result in bricking, so do check your GS4 model before you start anything).
I'll keep this instructions brief (Just google what you don't know).
1. Get root by flashing rooted (stock?) roms through odin.
2. Get a custom recovery by flashing Clockworkmod(CWM) or Team Win Recovery Project(TWRP).
3. Find out how to use CWM/TWRP
*Check the forums and use the search feature to get your way around. Any kind XDA member would continue elaborating on my brief instructions, do go ahead.
Happy flashing!
Cheers.

[Q] need help with firmware 4.4.2

Hi everyone, I need advice on restoring functionality to my i9505. I Odin flashed the NA1 stock leak because I thought it was required for echoe v16 rom which seemed to work but I had no wifi so I flashed the wifi fix from the i9505 stock rom thread for the 4.4.2 stock rom but it broke the sound and I still have no wifi now I gave a buggy stock rom with no wifi no phone no messaging amongst other issues and my Knox flag is 0x1. I have tried Odin flashing all sorts of bootloader modems etc but they either don't fix anything or they have an error while trying to flash saying FAIL! (Auth) in Odin and device says SW REV. CHECK FAIL : fused : 4 , binary 3. If anyone can please help me with a solution I would be very greatfull. I have Googled and looked through a lot of threads but still haven't found an answer. I know I've made a stupid mistake, just need help now.
1. Stop of flash things without read before. Flashing old bootloaders is horrible idea. This will create a paperweight soon.
2. The unique solution u can do is:
- Flash I9505XXUFNB9 (NEE) Nordic Countries-> HERE or HERE by Odin :fingers-crossed:
thanks Joku1981, im downloading now, it was a stupid mistake, I have been flashing and modding phones for about 10 years since flashing monster packs on a Motorola E398, I don't generally make these mistakes, I did a lot of reading before attempting this and it looked like others were having success but I just misunderstood the process. I am in Australia, not sure if that matters, is there any specific process to flashing this? will there be any steps to follow flashing with oden?

Im flashing for about 10 years too. But the Samsung bootloaders are one new big **** for all the people that love modify their phones
I know, its really disappointing, they should understand the potential of letting developers have access to the devices software by now, there are developers out there making way better stuff than the OEMs are. its almost starting to go backwards, you never used to have so much access as you have with the open source Android OS but now companys are clamping down on more and more of the device specific code etc.

Samsung devices now: If you was lucky and you received one Samsung with android 4.2.2, DONT UPDATE IT PLS
I flashed the file successfully, but I still have no sound and no wifi, things like phone and messaging are still buggy, any other sugestions?
yes my original bootloader was pre KNOX, I know, I have already ruined it now, no going back, almost enough to put me off modding all together, think im going to be up for a new phone by the look of it.
also my android version still says 4.4.2 and baseband still I9505XXUFNA1

Try to flash the combined package from here make sure to turn off your phone manually then wait atleast 10 sec and hold and press power Voldown in order to boot into downloadmode and open odin select CP/Phone ( .TAR) and flash

Well because you flashed a 4.4.2 kitkat..... and instead of you writing thanks to joku1981 there's a button right over there > feel free to click
thank you to both of you guys, you have restored my phone, I am so greatful for your help and generosity I have thanked you both and I will make a small contribution for your efforts, please advise Repulsa if there is some way I can make you a small donation for your help. one more thing, I am confused now as to which roms will now be compatible with my phone, will it be safe to flash Echoe v16 now? and what roms will I have to stay away from? thank you both again so much for your help.

Galaxy S5 chinese clone ROOT problem

Hello. Recently I got Galaxy S5. Then after trying to root it I realized it's a chinese clone which haa complicated my life. I tried to root it and put in a wrong version of Clockworkmod. As a result, I fortunately haven't bricked the phone, but my bootloader is not working anymore. It doesn't load up. Only thing that works is the factory mode. Now the problem is - I want to get the phone to it's stock ROM and firmware, but because there is no way to access bootloader, nor download mode, I can't use Odin to do so. Is there any way I could flash the phone with a stock ROM and make the bootloader work again? The OS works fine, only thing that doesn't work is the bootloader. Thank you.
Samsung Galaxy S5 clone (G900S - South Korean), MT6589. Android version 4.4.2 Kit Kat, Kernel version 3.4.5, rooted.
You need to identify what model you have, obtain the stock firmware for that model and restore that. There are forums that concentrate on the clone models, use Google to find them, and they will go into more detail about your options.
Beware that many things on XDA will brick or worse a clone as the apps and advice here are not intended for a clone which is completely different under the hood.

Thank you for your reply. Well tge stock firmware is secondary for me. The problem is with the corrupt bootloader. I think it tries to load the CWM, but due to it's incompatibility it cannot. Is there any way to replace the bootloader only? Without the working bootloader, I can't do anything to fix it or to flash a custom ROM. I haven't find anything related to it. Or at least not yet.

Try to get your money back bro. If it's a chinese clone s5 God only knows what it's running. It's not a Samsung nor an s5 for that matter so the recovery and Odin won't work.

Well, everything worked well until I tried to flash it. The reason was corrupt GPS. I found a way to fix the GPS but it required root and somehow I clashed it with incorrect CWM and the problem was born :/

Dude, get out of this forum or you`ll break your device permanently. You don`t have a Galaxy S5 and thuss neither a Qualcomm 801 cpu fow which these roms are build for. Find a forum somewhere for your device. Good luck
A normal (full) software image would include a bootloader. Separating a bootloader is much less common.
And as several people have already warned you.. quite a lot of the advice, procedures, firmware, et cetera on XDA will further damage your clone. Your clone may look like an S5 but it is very different internally. If you truly want a completely unusable phone, a literal paperweight, then continue.
Find another forum that has firmware and advice on how to program your specific clone.

Was the purchase of this clone made inside or outside of the USA?

Few questions on custom roms. (noob here)

hey guys, just want to start off saying that I love how helpful and informative everyone is on this site.
I've got a g900v that I newly rooted thanks to jrkrusem, I have installed the custom rom that he has on the tutorial through safestrap.
I figure i will ask before i continue and maybe brick my phone, I am slightly confused about the difference between bok3, bog5, boe1 etc.
I know Ive got a locked bootloader so no custom recovery but I would like to know which roms I can use. Basically I am looking for a little
clarification on this whole process if someone wouldn't mind enlightening me or even if there is a existing thread that I cannot find please leave a link. Thanks!

The last characters in the version designations are basically alphabetical, the order of which you can see here: http://samsung-updates.com/device/?id=SM-G900V
With BOE1 and up, the bootloader was locked which prevents a downgrade.
The custom recovery for our phone is SafeStrap: http://forum.xda-developers.com/verizon-galaxy-s5/development/safestrap-5-0-lollipop-t3313800

Can't find XAA or ATT binary 7 firmware. Please help

I have an AT&T Galaxy G950u with my most recent firmware being g950usqs7dtb1. I flashed a combination file (g950usqu7ask1) to turn on OEM unlock so I could install Havoc (I know now, I didn't have to do all that,) but now I can't get Odin to flash any stock ROMs back to install TWRP. The main error I'm receiving in Odin is FAIL! (Auth).
I've tried all kinds of ROMs but I can't find my original ROM anywhere except some shady site that definitely isn't legit.
When I boot into Download/Odin mode the numbers next to RP SWREV are B7(2.1.1.1.1) k6 S7
The error on my phone is SW Rev Check fail: (ab)) Fused 7 > Binary 1
I realized I probably need a carrier free (XAA) or ATT firmware that is binary 7. The problem is it's so recent I can't find any binary 7 firmwares out there. I've searched Updato and couldn't find xaa firmware for binary 7
Working with patched/modded Odin 3B v3.14.1
If anyone can help I would be so grateful.
Edit: I've tried Frija and it says ATT not supported, and it says it can't find anything for XAA. I've also searched Updato thoroughly and can't find a binary 7 file.
Edit 2: I found a ROM.

Well first off you can't flash any custom ROMs on this device it has a locked bootloader. Oem unlock doesn't matter. It's useless. Garbage. That's all for that. Flash any other carrier firmware and flash the oyn csc not home. It will repersonalize for att as the firmware are actually multi carrier. Att included.

Hey there @TheMadScientist not following you! haha. Just came across this thread as im researching what elliwigy and jrkruse have done.
To @uberdad search for anything s8 SM-G950 by jrkruse and elliwigy here and you should have a solution if your device is still on 7. Wont be twrp but will be safestrap twrp. You can install a custom rom then.

There are no custom roms. You can only have root on a 7.0 stock system img. Please research more before beginning to pass on information. As well this thread is now old no need to dig up old stuff. I helped out with some of the stuff on this device I know what it can and cannot do. Here wanted to install a los based rom. which is a big no. Add I said to begin with

Then he was trying to flash twrp. Which is a big no. Please don't go dragging up a bunch of old threads we have dealt with. This leads to confusing people

Hi. Yes you are right I should have said Slightly Cooked Rom or Modified System Image. However preferred to put Custom Rom due to the fact the amount of new Customization Enthusiasts here on XDA to make it simpler. Also sure yes USER Root on XDA only obtained on 7.0 (at least public). Little off topic but our team has a *working* root along with our own SuperUser which means for repairs pretty much but if time was put into it could become possibly a semi to full user root. I have used Magisk SU older versions along with our root and had a semi working user root on past Galaxies.. Anyhow we don't really have time, especially myself, to work on an actual user root for every device i/we work on.
In the world of forums threads never really grow old they just go into a deep sleep eventually....Until someone wakes it up with the thirst for knowledge. It's how the internet works when it comes to these here BBS/Forums/Blogs etc. =]
What he asked could be something someone else might ask or attempt trying (he shouldnt have even got as far as he did unless on international variant which makes the Q odd.. haha eh? however i felt the need to straighten it up for anyone who might read and get confused. See what im saying..? along with the previous statement about data no become stale.
The more ya know the smarter you become. Information makes the world go around. .. IMO Always best to keep it flowing constantly added to.
