Samsung galaxy note 5 (sm-n9200) need boot-loader unlocked failing miserably.... - Galaxy Note5 Q&A, Help & Troubleshooting

Good afternoon folks. Im a fairly experienced guy as far as rooting and installing custom Rom's go on Samsung Phones. In this case I have POSSIBLY, the Hong Kong version of the Samsung Galaxy Note 5 (SM-N9200) and while I was able to get a root on it with King Root..it's not my desired method. I'd really like to ROOT the phone, but I need to first unlock the BOOT-LOADER.
I've tried the CROM-APK but it won't install (I Keep getting "App not installed" every time I attempt it), and to my knowledge, I don't know of any other methods. IF anyone has a SHORT or LONG winded manner of doing this it would be appreciated. I've even tried the ONE-CLICK-ONE-TOUCH all the way around method and that was to no avail as well.
Also does anyone know if this phone is LTE Capable???? Would flashing a custom Rom give me access to that feature?
Any help would be appreciated.

OK! Update to my situation, I've managed to INSTALL CROM-Service But i can't get it to run on my phone. ALSO, there is no OEM-UNLOCK feature on my phone as well which im told can occur sometimes when the developr absolutely does not want you unlocking your boot-loader.
Is there a way around this????? How do I unlokc my bootloader without that OEM-Unlock feature.

i have the same problem

how did you do can i know

Need help with unlocking Galaxy S3 Mini

Hi guys, I'm trying to unlock my S3 Mini and I'm having no luck so far. I've managed to root the phone using the iRoot (former Vroot) program and it worked nicely. At least it seems it did, now it does ask me to give su eprmissions to allpications and busybox is installed.
As for the unlocking itself, I tried several methods. Firstly, there was some service menu, accessible by a long string of numbers on the dialer, then going to network lock menu and setting something there, but the menu isn't there. Or better said, when I come to the Network Lock, it says only Not Active and no further options available. Then I tried the GalaxSim Unlock just to see, but as it said in the notes, this version of phone is not supported and so it didn't work. Same with another app, Galaxy S Unlock, or something like that. That one needs busybox, so I installed the 1.22 I think, but it says that there is a problem with busybox or something. It does say in the notes, that recommended is 1.17 busybox, so I keep that as a backup hope but it seems again, that the phone is not supported...
So basically, I have a rooted S3 Mini, that is still locked to T-mobile. I'm not sure, whether the country of origin matters here, but I think it was purchased in Austria (I am not the first owner) and need to unlock it for slovak O2. So far I am actually very happy with it's stock ROM, so I'm not planning to flash it completely, just sim unlock. So if anyone has any idea, what I can do to avoid going to a phone service and have it done for money, I'd appreciate it.

Seriously noone has any idea how to unlock one of these machines? I've seen so many people talking about unlocking this and none of the methods mentioned worked. So please, pretty please, if you have any info on this, share it...

Upgrade path from B123

I'm running a P7 with the firmware it shipped with and I'd really like to get it up to date, but every package I've tried so far has failed during package verification. There seems to be very little info on how to update your phone from such an old build. Can anyone please help because I'm at my wit's end here. I have a limited date cap so can't just keep downloading updates in the hopes that one of them will work.
I would be greatly indebted to anyone who could help me. This issue is making me want to cry.
Do you have a phone with a provider/network lock? Which roms did you try so far? You may give B133 a shot, if that doesn't work you'd have to go the way over a custom rom and then getting back to the stock one. I can describe the process more detailed in case it's necessary.
Thanks for the response!
I think the issue is that it is a network locked ROM. I got the phone from a provider called Vodacom and get their splash screen and everything. I went to speak to them and they told me I'm not supposed to be able to update my firmware because that requires rooting the phone, which voids my warranty. Sales people being sales people, I'm not sure how truthful this is. I can't imagine a provider refusing to let you update your phone.
So far I've tried B133, B609, B617 and B853, none of which works, sadly. Someone suggested I unlock the bootloader and I got the unlock code through the Huawei site, but when I try to boot using the three-button method it tells me that no update.app file was found, so I'm not sure how to get to where I enter the unlock code.
Hm, you might search around a bit and find an easier way, but if not, unlock the bootloader, flash twrp and any emui 2.3 based custom rom. Then flash the stock recovery and make a forced update (3 buttons) with B133.
To access the bootloader you have to press volume- and power until a white screen with some text appears.
Anyway, to update would definitely be worth it.
Yeah, I did precisely that last night and ended up soft-bricking my phone. It wouldn't even work when I flashed the original firmware. It's currently in at a repair shop and I hope they can fix it. Lesson learned though.
Thanks for the help anyway.
It's not that easy to hardbrick the P7, it's very likely that he will be able to fix it! With some time for trying, you probably would have been able to do it by yourself, too.
Your very welcome
Yeah, the thing is I was up all night trying to fix it. Flashing it back the original software should theoretically have done it, so I have no idea why it didn't.

Mixed Results when ROOTING

Hi Gents,
ok so we all know by now that waiting 7 days unlocks the OEM option for the N8 950F, i want to root, my concern is that i have been reading and see that results are mixed, i have seen that flashing a custom FW has soft bricked some phones and you will have to flash back to official FW and wait yet again for 7 days for OEM to show up in dev options....
what i want to know is whats the sure fire way to get it to work (ROOTand CFW) because i dont wanna end up losing the OEM option and then have to restore OFW?
please let me know your thoughts and what you did to have a successful first time flash, my note model is N950F/DS.

You don't gain anything anymore from rooting that you used to. The phones are already lightning fast.

That's cause no one knows exactly why it disappears yet or has a valid fix for it. So far it seems like people are having luck with krabman's method.

In the past, people mainly rooted for speed tweaks & themeing but those aren't the only reason for root. Speed tweaks & themeing were never the main reasons why I rooted.
Like many I spent time in jail waiting for my OEM unlock. How I spent that time was trying to work around not having root and it was a miserable failure. When talking about the need for root I think it's best that the conversation first be understood to be subjective. A person that doesn't do anything that requires root will feel that it is unnecessary, those that do will consider it vital as a means to get where they're going.
There are many, many, people who said "you don't need to do that" in regards to getting root on these devices who went down in flames. No timer on OEM unlock and not a big deal, you try again until you get it right. We get one try and getting it wrong means you have reset your timer and you're waiting a week. Wait that week and you get one try, failure means another week. A person can repeat that cycle as many times as they want, I'd suggest going all in the first time because no one knows exactly which steps are not needed yet although we have ruled a few out. One thing that is apparent is once you have the first rom install in the rest can be done following normal rom installation procedure so long as they're clean flashes. I haven't tried any dirty flashes but for the same rom I'm thinking it will work, of course when the time comes I might be proven wrong. I'm hoping someone else will get there first and I can take advantage of their experience.
That being said in general the process begins by flashing TWRP in odin. You must leave odin and go directly to TWRP, failure to stop the boot at recovery means a certain binaries error and a week wait. Once you are in recovery you must stay there until you have finished installing a rom that has been de-knoxed. Pay attention to holding the buttons on the phone while you start the TWRP flash as described in the TWRP thread. If you untick reboot in odin then the only way out is to hold volume down/ power which will tell the phone to reboot into system. You must then quickly switch to volume up/bix/power during a small window in order to get the phone to go to recovery. If you miss it nothing can stop the phone from continuing to boot and you have just got a week wait before your next try. If you don't untick restart you can try the same thing when odin automatically reboots the phone after the flash. If you miss it you will get the binaries error and be waiting a week. People have missed it both ways. There is a reason that the TWRP instructions specifically state to prepare odin, hold the vol up/bix/power buttons and continue holding them while you press the button in odin and keep right on holding those buttons all the way through until the phone boots into TWRP. This makes it a sure thing, the other way you may or may not succeed. Lastly we've proven you don't need to remove your SIMs on subsequent rom installs but it remains a question with the first install as there are conflicting reports. If it were me I'd pull them and not put them back until I was fully up and running on the other side. You will need to pull at least Sim 2 in order to put in the micro SD with your rom, verity, and root firmware for use in TWRP no matter what. Feeling frisky and you want to leave Sim 1 in then please report your results in the OEM unlock thread.
So... To install a rom you will begin by following the TWRP instructions to the letter including the format all the way through the process until the end. Some will say you don't need to flash the no-verity, ordinarily I'd agree with them as it is flashed as a part of both the SU and magisk flash but in this case we know that following those instructions in exacting detail works as a first step but not doing so has been a failure for many. Because few have followed the same steps plus or minus a detail from the known working method we don't know exactly which things are unneeded so if it's me I would just follow the known working method. As always those wanting to advance our knowledge by trying something else should report their results in the OEM unlock thread. When you reach the end of the TWRP installation instructions you will remain in recovery and flash your rom and then factory reset. Then flash either magisk or SU again depending on which rom and which root method you're using. Once root has been reflashed you can go ahead and boot to system. Finish the setup before you put the sims back in the phone.
There is a longer throw the kitchen sink method in the OEM unlock thread for those that wish to search, that is what I would do if I wanted absolutely no risk as it seems to work without fail. I've done what I describe here a good ten or more times now as I was the first reported rom install here using the first method and I've been flashing away since then and dropping some of those original steps as I went. I'm thinking it should work for others too but I cant prove it until someone does it. It may be you need the kitchen sink for the first flash, I simply cant say because I would have to go stock to try and I'm not harboring much of a hankering to do that. This being XDA and we being adults please understand that I'm sharing the information based on actual practice on my own phone but there is no guarantee. You make your choices and what happens, happens.

what do you do to restrict recovery access on rooted note 8 ?

hello all,
i have been wondering and searching for quite some time on scenario when you lost/misplaced your rooted phone and want to have piece of mind knowing for sure whoever find it can not access your personal data. is there such an apps/utility/setting that will enable us to do so ? on unrooted phone we have frp lock and google lock. since we rooted our phone those 2 features are no longer able to stop anyone to get into recovery mode and do whatever they want.
i found a topic of twrp password protection https://forum.xda-developers.com/android/software-hacking/twrp-password-protection-thread-t2990816 but is not fruitful according to devs.
any of you have been thinking the same with me ? what did you do ?
many thanks !

Samsung: worst ever for a power user!

Today I got up real pissed with Samsung for being so restrictive around ROM flashing, rooting, flashing custom firmware or even stock firmware, so wanted to create this post to help anybody considering to get a Samsung phone to stay away from it.
This post is not intended to recommend any specific brand or model of android phone, but to recommend the exact opposite, which brand and model NOT TO EVEN THINK of purchasing.
This post relates to Samsung Galaxy S9 G9600 model which is Snapdragon architecture, but since Samsung is coming up with a bunch of "security features" I tend to think this may be the case for other models as well. I browsed all around XDA and other sources for guides on how to root and install custom roms, and it turns out Samsung manages to have limitations for EVERY step of the way.
Getting a few facts straight
Reference post: https://forum.xda-developers.com/ga.../rom-lineageos-17-1-s9-s9-snapdragon-t4093301
Ok, so there is a solid thread about a custom firmware and looks like several users got hands on it, but they might have been able to get passed though all Samsung security crap before it came out or before it got so tightened up. I'll list below every limitation I found:
OEM Unlock
There is a step where we need to tick OEM Unlock from the phone developer settings, it turns out Samsung has put a 7-day timer for this option to even appear listed to enable. If you do factory reset of the phone, the 7-day timer restarts. There are a few posts around on how to get passed this timer, but to me they were all crap, none of them worked. STRIKE ONE!
Bootloader unlock
After 7-days, we get the OEM Unlock option to appear, at this point you may think: Hurray!! .... WRONG! Now next step is to unlock the bootloader using an utility called CROM Services... And as you may have already guessed, did not work! I'm able to install the apk, but on launch it complains about wrong android version. (Tried with Android 8 and 10) STRIKE TWO!
There are some posts and guides claiming to be able to unlock bootloader by using fastboot utility, I can't reach to understand how, since fastboot commands rely on the bootloader to be previously unlocked (?). I least that is my understanding, correct me if wrong. Needless to say fastboot did not work for me. ADB lists my device but fastboot doesn't. There are a few troubleshoot guides around to try selecting proper USB driver from windows device manager, tried all that, tried a couple of ADB installations, fastboot didn't work.
Knox and RMM state
After some lookup in the web, Samsung incorporates some security features trying to prevent device theft and such things. For us power users this is in reality just a whole load of crap preventing us to get all the juice out of our phones.
Reference: https://www.goandroid.co.in/unlock-bootloader-of-galaxy-s9-plus-snapdragon/84688/
TWRP Recovery
Next step would be to flash a custom recovery such as TWRP with Odin or adb/fastboot, but since we are not able to unlock the bootloader in previous step, this is not doable at all. STRIKE THREE! OUT!
Fastboot utility doesn't recognize the device in download mode, so we can't send any commands to the phone.
Odin complains it is only able to flash signed stock roms, so since TWRP is not, we cannot flash it.
Rooting
Needless to say that if we don't have TWRP, we cannot flash the corresponding packages to root. Although this step may not be needed to install custom firmware, rooting has not been possible.
Stock ROM Flashing
Ok, so let's stay out of custom firmware - let's play around with stock firmwares. At this point, since flashing stock firmwares is kind of allowed by Samsung I was able to try out a couple from android 8 to 10 with Odin
Stock ROM Source: https://www.sammobile.com/samsung/galaxy-s9/firmware/#SM-G9600
But watch out! Once you get to install a specific build version, you cannot go back or downgrade to ROMS with previous Android build version. So now that I got Android 10 cannot go back to 8 or 9, this is probably because locked bootloader and unable to unlock. Here, Odin complains with FAIL! (AUTH) message.
STRIKE FOUR! EVEN OUTTER!
SIM Unlock
Ok, let's stay out of Samsung S9 G9600 model, let's crash it to the wall and throw it away to the garbage! Ok no, let's have it carrier unlocked and sell. Unlockbase is a well known and trusted sim unlock provider, I purchased a license to unlock by USB cable, but... GUESS WHAT! G9600 is not supported for unlocking operator network with this software... what a surprise!! I was able to apply for a refund and got my money back, so no worries here.
Note that flashing carrier free ROM does not unlock sim to use with any network operator.
I'll be trying to unlocking by code soon, as this is based on IMEI number, I may think this is independent to the phone model and edition, so I hope I have more luck with this option.
Conclusion
G9600 is a really crappy phone to mess around with. I may have ran low on luck with this specific Samsung Galaxy model since I got it as a gift, which is the latinamerican crappy edition. I wonder if other S9 editions and other Samsung models run with better luck than mine on this scenery... But as a lesson to myself, I will stay away of any Samsung smartphone in the foreseeable future.
OEM Unlock
The 7-day lock prevents stolen phones from being factory reset, leaving the thief with a phone permanently protected by your account. While a minor inconvenience, it's actually effective and not the worst compared to other manufacturers.
Bootloader Unlock
After OEM Unlocking, flashing TWRP through ODIN is effectively unlocking the bootloader. This is possible on both exynos and snap.
Knox and RMM
While this is an inconvenience, from Samsung's point of view, it's worth it. It makes the phone look more secure in the eyes of potential customers. If you really wish for NFC payments, I'm still able to use GPay with Magisk on a custom ROM.
TWRP Recovery
TWRP is flashed through ODIN, not fastboot. Look up an actual guide before complaining.
Root
Yes you can
Stock ROM Flashing
The one thing I could agree on with you is Samsung disabling OTA updates when OEM unlocking. I don't see the point really, but you're free to flash whatever you want through ODIN. Downgrading shouldn't be an issue. Not sure what's up with that.
Before buying a phone, how about you do some research before crying on forums. As a power user coming from the Oneplus One, I don't regret going for Samsung in the least.
Thanks for your reply, I had dropped all hope after several attempts over last few weeks. Found this option and I was able to get past my blocking issue with TWRP and moved on.
https://forum.xda-developers.com/ga...er-development/g9650zhu6dta7-android-t4051751
I have G960F and have to admit I totally disagree with your original post. I've been using custom ROMs on nearly every phone I ever had and don't think S9 (G960F) is bad in terms of unlocking. Just did an OEM unlock, waited a week, flashed TWRP through Odin, booted straight to TWRP and immediately flashed a custom ROM from it (because a boot to the stock ROM would replace TWRP back with the stock recovery IIRC). In the end I got sick of all the problems with Magisk and non-working google pay that I went back to the stock ROM - making S9 the first phone I use with a stock ROM even though it can be flashed. I think it's a great phone for power users.
And as far as SIM unlock goes - Samsung is not to blame, the carrier the phone was made for (and purchased from) is. Phones that Samsung itself sells are unlocked. I wonder why there's still some countries where SIM locking remains legal.
This thread is a prime example of how people end up with bricked devices. So much misinformation in one page LOL
I had the 9650 and most of what I'm doing here is user error. This was one of the best devices I've ever owned. I mention of fast boot and such you obviously just do not know samsung devices. You can't blame samsung on your own ignorance
