about write protection?? - Droid Ultra Q&A, Help & Troubleshooting

OK, so I've been doing some reading around the forums and obviously from what I have gathered there is currently no way to obtain WP off or BL unlock on 4.4.4 atleast not on SU6-7 or higher. Atleast I haven't seen any way so I'm assuming if a method does exist then its being closely guarded for now and not being released.
My question isn't about rather its possible or not, I'm sure there is probably a way just not one that has been found or is publicly available. My question is, assuming you did have an exploit that would allow you to remove the write protection how would you actually go about doing it?
I have some free time and access to a second unused Droid Maxx so I was considering poking around. Looking for exploits in software security is kind of a pass time hobby of mine and I have a little training from previous military training. I by no means am an expert but I figure it can't hurt to play around with the second phone that isn't being used (has problems with speaker not working etc). Anyway, I realized I need to learn a few things and can't seem to find any real info as I was reading around on the forums about how write protect off is actually achieved once an exploit gains access to do so.
Worst case scenario I learn a bit of useless info is the way I see it, kind of like reading an entire write up of how the motorola bootloader was being unlocked before they blocked the exploit in these phones. Doesn't help me but its information and I love to learn new things, even useless ones.

OK, so I guess nobody who knows cares to help me out. I was hoping to try and find a way to achieve write protect off again but its hard to find a valid exploit and method when I'm not sure what I need to do to turn off write protect. I am assuming its in the kernel somewhere as I can edit system the same way I rooted on 4.4.4 SU6-7. I don't know what needs to be changed or where its at though so not sure how to attack it. Would love some information, not asking for any other assistance.

All I now is that wp is set in the kernel of the phone, I think at least

From what I managed to learn the permanent off was achieved in aboot. I've moved on to exploring the tz kernel, figure if I'm going to spend hours deciphering binaries might as well go for bootloader unlock instead. Don't know if I'll find anything as I'm having to relearn assembly as I go also but who knows

Worth Rooting?

I just got the MT4GS after being a long time MT4G user and I'm wondering if it is worth it to root as there is currently no CM or stable Virtuous Rom which is what I used on the MT4G. Any helpful opinions are much appreciated.

If Virtuous is what you like then I'd say yes, go for it and root. The Virtuous ROM might be in beta here in the MT4GS forums but it was smokin' fast and stable enough when I used it. I'm sure an official release is just around the corner anyway. good luck and welcome to the MT4GS family!!

Thanks for the feedback and welcome, good enough reason for me. One thing I do like a lot on stock is the camera app, is that included in the beta or is there a flashable mod?

Root it. Then you can:
Enhance your gps ability because of the generic gps file that's coded very poorly (in fact wrongly ... T-Mo doesn't maintain a good SUPL server, and if you're not on the T-Mo network your AGPS isn't working in stock configuration...well, maybe a little, but not anything worth mentioning. )
Flash a better security update to fix the big-brotheresque HTC spy mode (htcloggers.apk). HTC released an update to patch their security hole, but they are still monitoring everything you do with the device. Flash Undeadk9's security patch to just cut them off at the knees instead, or uninstall htcloggers.apk ( and other file I can't remember at the moment )
Change your hardware key files and re-map some buttons to be more useful.
Flash custom ROMs, as you're aware...
Play with the upcoming kernel files from myself and others...( give us time to make it stable )
...and so much more!
Generally do the things with the device that you've paid for that you should be able to do. Why spend all this money on something, and only use like 60% or less of what it can do?
If you're here and posting, then you should probably just go ahead and root it. It won't be long after you've been poking around in here reading through all the things we have been/are doing with the device before you'll go for it.
Check the sticky at the top of the general section to get a good handle on where to go first and what to read through. Take the time to read through the threads ( I know they are long ) - you'll see what all the problems were that people encountered, and how they were solved. Even if you don't run into the problems, at least you'll learn a whole lot and understand your device much, much more intimately.
...and if you get stuck, we're here to help. Many of us have been through this whole process countless times before, and are willing to lend a hand - just don't post random questions in the dev section and everything will be good.
Welcome to our little corner of the XDA universe - you'll love this device!

Wow, thank you for all the info, I am very grateful. I've noticed there are a few threads detailing how to root but can you tell me which one would be the best and most reliable? Thanks again for all the info, especially about that HTC spy stuff, I had no idea.

Thanks man! Got it rooted and running senseless! So far so good!
Not to contradict Shady's advice, especially since it seems like it worked for you, but i've previously and still do recommend against going to a third party web resource outside of XDA to root the device.
The reason being is that a lot of us did everything from the information available here, and we are familiar with the processes and common problems people run into following the guides posted here in the forums.
If you post questions about problems or an issue you run into, you run the risk of slow or no support because of the unfamiliarity the majority of us here have with outside methods and resources.
I know off the top of my head I could post a helpful response to someone having a problem with a method described here. For an outside resource...i'd probably have to go look it up, maybe download somehing, and probably try the method before being able to help.
Then i'd have to dig into the code of whatever offering was in question, to ensure it wasn't doing anything I didn't want it to do before installing anything.
Ultimately, this is a lot more time and trouble then just digging into my memory or looking up a specific thread to verify something, and also probably provide a link to the specific post that addresses the problem.
I'm hitting overtime consistently on my night job, and still picking up hours at my day job, and honestly would rather commit the level of time necessary to troubleshoot an outside resource on something more personally productive, like digging deeper into kernel source or something.
Just a thought to keep in mind as you (and others in the future) wander around here. I promise that everything you need to root your phone and install custom ROMs and such is right here in the MT4GS forums. (excepting the need to go to the revolutionary resource for S-OFF).

Very true. They use a lot of information found at xda to build their guides off of thou. And a video tutorial is always nice, for me anyways. but yeah.. don't expect support from theunlockr.com.
I always go their, sometimes their outdated or wrong. But still gave me a general idea and I was able to use multiple guides to give me the correct process..

I'm glad I was able to find this thread, cause I've been wondering whether or not it would actually be worth it to root a MT4GS or not. And ya, I can agree that for the most part, rooting has more benefits than problems. And I always have gotten the same answer when asking that question about other devices, "Just root it; you'd have to be crazy not to; nothing compares to a rooted phone, etc...". So I gave in and rooted my MT3G 1.2 (w/ the headphone jack on top). After a while I noticed some definite problems: a few important features were gone, also it was impossible to update G. Maps (because of being rooted), and finally the worst scenario of all: not being possible to un-root the device. I must have tried 10 times, following the directions to the T and repeatedly getting the same failure error. I was finally able to find someone else with a similar problem who posted their solution. Tried, waited, failed. Fully bricked, I mean not even a flicker or a battery light would come on after that. Fortunately, I was able to lie to customer service and convince them to do a warranty exchange (Aeon-1, T-Mobile-0) so I got a replacement and haven't rooted since.
So I guess my point is, I'm actually scared to root my new MT4GS for the sake of potentially not being able to unroot it if need be. But, so far from what I've read it looks like it is reversable if I ever need to. I was likely considering using theunlockr.com's method due to clearly stated, and easily understood instructions. I wish I could say the same about the posts I've read @ XDA regarding rooting instructions.
-Which rooting methods are guaranteed to be un-rootable? That option is crucial, if I ever need to go back to stock or do a warranty exchange (for all those people who were gonna say "Why the hell would you ever consider unrooting?)
-So some people suggest ClockworkMod Recovery, others don't seem to care. I ask, is there any real difference between the two? And why?
-Also, which are the best/most stable roms you would suggest? Because I've done the trial and error thing before, comparing several different roms, and I never seemed to find anything worthwhile. (Also, I checked CyanogenMod's site and either I'm blind or they don't have a single rom for the MT4GS)
-I think you somewhat answer the question regarding features of the stock camera being available after rooting. But I need to know: After rooting, is the camera going to be the same as the stock one, including ALL available features (SweepShot, ClearShot HDR, Burst Shot, Macro, Night...)? And is that camera program featured within all rooted roms, or does it have to be installed seperately?
-And ditto that question in regards to G-Maps.
-And finally this may seem like a n00b question, but I've still never gotten a clear answer: How/When can a Nandroid Backup be performed? I know that it would be a safety precaution in case I ever f*cked up my device and needed to restore, but I've never been able to find clear, accurate, and relevant instructions on how to nandroid backup or even nandroid restore.
So I apologize for asking so many questions, especially since I imagine they seem redundant and novice. However, I have rooted phones before so I'm not a complete n00b; I'm just trying to be VERY thorough this time around, to avoid any potential for error. Thank you in advance for your time.

Sorry to hear that didn't work out so well. I think you'll find that your MT4GS experience will be a lot better.

Yea, everything tends to happen first here, so trying to keep it all organized as things change and develop is difficult at times, much too convoluted at others.
Basically, you need to take your bootloader from S-ON to S-OFF. Do this with the Revolutionary exploit. It installs CWM 4.0.0.8 during the process.
Then you need to make a nandroid backup. (see my backup thread)
Then you should upgrade to the official Clockworkmod Recovery, replacing 4.0.0.8 that was installed with the S-OFF exploit. The version is 5.0.2.7
Dev section link for the official CWM:
http://forum.xda-developers.com/showthread.php?t=1329160
Once you do that, you should already have the superuser.apk you need for rooting that you found when you got the Revolutionary S-OFF tools. You can either have done it then, or now.
I'd wait until after getting the official CWM first, simply because that makes your first nandroid backup as fresh as it can be. It's up to you when you do it.
And that's basically it.
You now have a stock, rooted phone that you can start to play with. I'd say play with it for a little while on the stock ROM before switching to another, that way you'll get a feel for what you gain or lose, and if the various trade-offs are worth it.
Before doing any of that stuff, though, read through this thread:
Read this before posting. MT4G Slide Compendium
That will get you a little more familiar with the terminology, and provide helpful links to start exploring what you need to know.
Also read as much of this thread as you can stand:
S-OFF for Retail (S-ON) Devices, NOTE ADDED 8/17/11
This S-OFF for retail is the thread that officially announced the Revolutionary exploit for S-OFF here. The links in the OP will take you to where you need to go to get it.
If you get through that one, then this is a follow up:
PERMANENT-ROOT (NEW!) & Temp-Root (v2) for any MT4GS (Windows)
The temp-root thread is a bit confusing, because before we got S-OFF you could root the phone until you rebooted it. Once the Revolutionary S-OFF method was out, this thread also ran tandem with the official announcement thread. Because it was also dealing with temp root, it led to a lot of confusion.
There is some really good info in that thread, but I recommend reading the official release thread first. It'll make more sense that way, and you may not even have to check the temp-root thread.
(again, this lends to the evolving nature of what we're learning here - hard to keep it organized as it grows.)
Also, this thread: How To Turn S-Off, Install MoDaCo Clockworkmod Recovery, and Install a Rom For Dummie
Was written as a summary on how to get S-OFF and Root, because of how convoluted and looong the two previously mentioned threads got.
Once you hit this point, you're basically set.
My next move would be to install busybox, which you can find in the market, then immediately flash the Security patch to fix a glaring security flaw created by HTC.
At this point i'd make another nandroid backup.

They are all un-rootable, but once you go from S-ON to S-OFF that's a one-way trip. Several people have reported exchanging their devices after returning to stock with an S-OFF bootloader without issue.
This is returning to T-Mobile, though, it's questionable if HTC will accept a return directly of a device with an S-OFF bootloader.

I'm working on releasing the updated version of Bulletproof right now, actually, and you'll like that one. Should be out in a day or so. The original developer is moving on and is handing it off to me.
I've just spent the last....dunno how long working at it, and needed to take 5 and clear my head. Cruised through the XDA MT4GS forums as i'm winding down for a break, and you caught me at a good time to give a response.
CM7 just got officially put on hold, but with your interest in the camera you probably wouldn't have gone for that right away. It's an alpha release, and we are very excited to have official CM support for the device, but since Ice Cream Sandwich ( Android 4.0 ) source code was just released, the CM team is focusing on that and it's likely to be a while before the CM7 for our phone sees an update.
Honestly, i'm more excited that they are focusing so exculsively on Ice Cream Sandwich, because that means a lot more for all the phones and devices beyond just our own version of CM7.
I'll leave other ROM recommendations to others who will surely come through here and tell you more about them.

Pretty much all of the ROMs will support both the Camera app (in its entirety, included in the ROM) and Google maps.
The alpha port of CM7 is the only one (pretty sure) that doesn't support the camera, because the camera is tied into the sense frameworks. CM7 has no Sense components to it, and it was stated very clearly in the thread that it never will. The CM team and their ROM is worth losing the camera app over to a lot of people, and they are the lone exception to the "no camera app" stigma.
Keeping the camera app is one of the things that has been driving development around here, and very few people were willing to use or invest time in making a ROM that would exclude it.
I should take this time to point out that the stock gps configurations are, well, flat out wrong. Misconfigured, and it doesn't work well.
Myself and another developer independently spent a lot of time working on fixing this issue, and when we realized what each other were doing we also realized that we had the piece of the puzzle the other needed to make it work.
We released a collaboration that solved the problem, which you can find here: GPS lock too long or not at all? Try this
If you want to know how my half of the puzzle works, that thread will explain it in almost excrutiating detail. I recommend my patch over the other developers, as he is no longer with us and I will only be continuing support in my thread.

Honestly, don't ever worry about asking too many or too long of a question, as long as you don't post the question itself as a new thread in the development section of the MT4GS forums.
I'm sorry to hear it took such a bad experience for you to become as cautious as you are, but now that you're long past it you are much better off.
I'd much rather see someone ask questions, read some stuff, ask more questions, and then act on knowledge then just go and do and then say "I broke it, what do I do".
I'm happy to help either way, but if the information is there already then reading it before you start is much better then retroactively. Save the "how do I fix it" for uncharted territory learning things that aren't already common knowledge.
Again, part of the problem is that information is so convoluted because we keep adding to it as we learn new things. You can't really structure it before you know what it's going to be.
Myself and a few others have been trying to put effort into organizing things, but it's really a monumental task and i'd like to develop new things more so then catalogue what we already know. It's a crappy balance, but I try to put equal time to developing and organizing/answering questions.
I hope this helped you out some, I know I didn't completely cover it all but it should give you some things to chew on and help you sift through the data by spending more time on the relevant parts. Even then it's still a lot that you should know.
Don't be afraid to ask questions, one of the reasons I go into such depth is because people can correct me precisely where i'm wrong if I am about something.
You learn more when you're willing to admit you don't know something, then to pretend you do for whatever reason. Asking the right questions depends on being honest about what you do and don't know with yourself, so fire away.
I've got to get outside for a few minutes, then get back into coding, but someone else will come along and add to this soon enough.
Take care!
Well I definitely very much appreciate your prompt, and very detailed response to my many questions. I've been reading over what you've written plus the links over the past day. The main issue I have is digging through each thread looking for relevant information, while trying not to get sucked into each and every tangent post/link/info. I lost track of how many hours I've wasted reading irrelevant info which I initially thought actually had something to do with what I was after. And now a day later, I have my desk covered in reference notes (which are no longer comprehensible) and I'm more confused than I was before.
There are plenty of issues I have with forums in general. First of which being, organization seldom exists. Its like going into a library with a single question about 'how to change a tire', and leaving with 15 random, heavy books on quantum theory and black-matter, because apparently someone implied they were somehow related (I'm referring to other people, not you). Discouraging to say the least. I thought this would be more black-and-white; more simple. When 'Android' was new, rooting was simple (less ways to re-invent the wheel).
I'm walking away from this for now. The headache isnt worth it (I literally feel like I got skull-f*cked by god himself). But thank you for your help and feedback.

Hah, yea, XDA is like that all over - just the nature of the beast.
This is not the quick-answer type of home, yet from a developers point of view there is no better place on the internet for android/phone development information and help.
It really does all start here, and the journey of discovery is much more prized and worthwhile then the actual end result. In that respect the way XDA is, is the way it should be.
Sometimes the best way to come to grips with something is to forget about it for a little while. Let your mind work it over running in the background, and when you bring it back into focus you'll have a better hold on what you need, and what you still have to learn.
Again, feel free to ask any questions you may have and we'll do the best we can to get you set in the right direction.
Ya, it was like mass overload the other day; it was like trying to make a PBJ sandwhich, then realizing I have to bake my own bread from scratch, grind up peanuts into butter, and somehow pick my own berries for jam, etc...
Anyways, I read over some of those topics again and some of it makes a little more sense. But still, some of those threads are so damn long, Im not gonna read each and every post from top to bottom of the thread, at least not yet. But the main issue I've realized is definitely going to be a problem is the fact that turning S-Off is irreversible. There is absolutely no method of turning S-On after its been turned off, which doesnt seem to make any sense; I figure, if you are able to flip a light-switch on, its only obvious you should be able to flip the switch off. So why is the 'S-Off' method a one-way path? And is this problem going to be fixed?
I read a bunch of articles and tutorials on 'unrooting' the MT4GS, and each one says that it will change the phone back to the stock factory condition it was in before rooting. Of course, once I scroll down and keep reading comments, everyone says that there isnt a way to turn "S-ON". SO, how the hell would someone be able to root their phone while still ever having the option to do a warranty exchange? Unrooting is great cause it gets you most the way there. But I've been reading that when T-Mobile recieves the phone, they send it to HTC for inspection/repair, and thats where they look at all the software/firmware/h-boot/recovery/S-ON Versions to make sure they are at factory specs. So once again, even though it is possible to "unroot" the MT4GS if need be, it still impossible to fully go back to factory standard (which is exactly what I was worried about).
Thats ****ty cause I was actually willing and ready to start rooting via theunlockr.com's method (cause its a hell of a lot easier than any tutorial in these forums, it does it the same way, its just easier to understand). BUT, that S-ON/S-OFF snafu is enough for me to reconsider. As I'm sure there are tons of benefits to rooting and therefore I may not ever want to unroot, I still may need to for the sake of the warranty exchange. And believe me when I say that I NEED to have the ability to exchange; I've had to exchange the MT4GS 5 times within 3 consecutive weeks because each one I recieved in the mail had some physical manufacturer defects. And since the most recent replacement is a refurb, I need to leave that Warranty-Door open in case I need to exchange.... again.
By the way, I forgot why S-Off was required in the first place. Is it possible to remain rooted without S-Off???

not permanently. you'd have to temp-root every time you reboot.
Revolutionary is about the easiest way to root a phone in existence so I'm not sure why you're so scared... assuming you have adb working, it's literally as easy as plugging your phone in and opening a single file in the Revolutionary zip archive. everything is done for you. as long as you don't download their faulty recovery (it will ask you if you want to... just say no), it's literally the easiest rooting method available that I've ever seen.
don't make it too complicated. I certainly believe in having all of your bases covered, especially when it comes to potentially screwing up a $500 bundle of plastic, metal and silicone, but rooting is not a big deal anymore.
many people will tell you that they have received warranty replacements after sending in S-OFF/rooted phones. my best guess would be that HTC/Tmo randomly pick phones to "thoroughly check" and the majority don't receive this type of treatment.. and even if they find a rooted device, there's no telling whether or not they will deny your replacement.
I received a warranty replacement (faulty hardware buttons, the leds never turned off) for my gal's rooted MT4GS simply by installing the stock rom and recovery, but still with Revolutionary's hboot installed. No issues whatsoever. I'm not saying it's "right" and I'm not guaranteeing you the same result, just offering my first-hand experience.
here's how you can obtain perma-root and s-off in ~10 minutes. no complicated guides:
www.revolutionary.io
download installer, enter serial # to get your code.
open archive and find the installer... let it run.
when it's done, you'll be rooted and s-off with a custom hboot. say "no" to the download recovery option and manually flash the official CWM recovery, or modaco's 4.0.0.9 recovery image. (either should be fine, although roms are going to start coming out that may have issues with the 4.0.0.9 modaco recovery so cwm is probably your best bet)
if not being able to flip the S-OFF switch back to S-ON at this point is something you can't get over, this isn't for you. personally, I spent $500 on this phone and I'm going to do whatever the hell I want to it, and if TMO and HTC have a problem with that, I will happily take my business elsewhere.
Its not rooting that I'm worried about, its the possibility of having to do (yet another) warranty exchange and being caught sending back a warranty-void device. And since I just found out that my premium phone insurance extends my warranty for an indefinite amount of time, I imagine that i will undoubtedly be exchanging this phone sometime in the future. I can only hope that by then either the S-Off thing has been fixed or T-Mobile announces they no longer care. I can see both happening, honestly.
Rooting is going to be the easy part, if/when I decide to do it. The last things I havent yet figured out are:
-Which Rom(s) I'm going to try. When I compare most roms side by side, they all seem vaguely identical. I remember Cyanogen having the option of fully customized visual aspects/themes, as well as tons of settings/features that werent offered through other roms. But the problem with CM is that, as you said before, the several camera options/modes in the stock rom are not being used by CM. I'm looking for a rom that is, above all, stable; lightweight/fast; includes all camera features of stock rom; and if apps like gmaps wont be included, I'd like to be able to find something that is comparable, or even better if possible. If not, I really hope the market allows gmaps to be installed on a rooted device (a while back on my rooted phone, the install of gmaps would always fail) Also, you had mentioned that you were nearing completion of a Rom of your own, so I might read up on that as well.
-I read up on that article on micro sd cards regarding speed comparisons, so I ended up running the benchmark app on my pc and found that my SanDisk 8bg Class 4 was (apparently) faster than my currently used Samsung 16gb Class 2, which sucks cause I like having more space than I use. But anyways it got me thinking, I realize that speed is important for file-transfers and also running apps that have been moved to the sd, but I could have sworn I remember someone talking about how they had rooted and then installed their OS/Rom onto their SD card instead of the phone itself. I dont know if I read that wrong or not. And if that was accurate, then I want to know if there is truly any benefit from doing that or not.
-Also, in regards to sd cards, I remember last year when I had a rooted MT3G with Amon Ra's recovery, there was an option to throw in partitions. Almost everyone I talked with on here told me to add a partition. Then after a few updates to the recovery, I noticed new options in the partition section: Ext.2, Ext.3, and Ext.4 as well as the options to select the partition size and "swap" size. I never did understand what exactly the difference (if any) between "Ext.2, Ext. 4.... etc" was.
And as far as the "swap" size, I remember there being a LOT of debate over what exactly this number should be. Some people started suggesting outrageously high numbers, while others explicitly explained to not do that, because apparently the lower the number the faster it becomes. Ok, so if thats the basic concept, great. But I still never did find any reliable information regarding "swap" size.
So ya, those are the final questions/issues that have been bugging me. Any advice/help is greatly appreciated.

Exactly how do you root a phone?

I've always been curious about the way the developers/"hackers" actually root/unlock the phone. It seems that many release their rooting/bootloader unlocks but never explain how they did so. Why is that?
It just doesn't make sense that people go through all the work and never explain the how and what...So, my question to all of the bootloader/root developers is; how did you figure it out/get it working/un hard brick/etc. your phone? What exactly did you do to root/unlock your phone?
Note: I'm referring not to the '1-click' utilities that people use, but rather to the people who made them (Just to avoid confusion).
The only resource I've found on how someone unlocked a bootloader is the azimuth security blog post on unlocking the Atrix HD bootloader (I can't post a link)
Yes, I would like to know this as well. What little I do know, is that Developers use SDK/Android tools for the rooting (and as far as I know, unlocking the bootloader) process.
I'll admit my guilt in not searching XDA for these answers, but hopefully someone will chime in and give us a path to follow.
is that mean we must mastering java languange to be able modifying? or is there anothar way?

[Q] In way over my head regarding a Android stick (Mk809III)

Hi guys
First of all, I am not a programmer.. Not even very tech savyy, so if "ordinary" people isn't allowed to ask around here, I apologize. I would also like to mention that english isn't my primary language, so also please forgive me for my bad english.
My problem is that I am in wayyy over my head. I bought an android (hdmi)stick over Ebay and actually kind of expected it to be plug and play. After a bit of playing around and reading up on it I realize that this is far from the case.
The item is an Azurill MK809III
I have the following problems:
When I am trying to use apps that requires a rooted device, they say it isn't rooted. When trying to use apps that doesn't allow rooted devices, the app says it is. I am quite convinced that it is, but I don't know why various apps (also apps which only purpose is to check for root) says it isn't. I would, solely for that reason like to find another (still mediacenter-friendly) rom.
I also find the movies kind of choppy. According to various posts on the internet, it's because of a problem in the way the stock "kernel" handles things. I've read various recommendations of which alternative kernel that should be used. I don't know if another rom will solve this problem also?
The problem is that it's a JUNGLE out there. I honestly don't know how to flash a rom, and when reading up on it it seems VERY complicated. I know from earlier escapades that tech-things often look more complicated in writing, but what worries me the most is that all the guides that I found includes some kind of code.. Is that Linux? And does that mean that I need to have a computer running Linux to do this?
I am a totally virgin when it comes to tampering with things on this level.. I honestly thought it would be a nice "out of the box" alternative to a Chromecast, but boy was I wrong.
Can anyone save me? Either by guiding me through the whole process or maybe just tell me if this is possible without Linux and pointing me in the right direction(s)? I fell over something called "Rockchip Batch tool", but I don't know if that can be used for the process or only to flash back to the stock rom (or maybe I totally misunderstood what its for)
I am of course kind of afraid of breaking my device, so I don't dare to start following some guide on my own initiative, unless someone assured me that it is the right thing to do.
Thank you in advance.. :fingers-crossed:

Bump..

I really want root

I'm a noob at programming and I want someone to make an exploit to root SM-G950U on Oreo. I got this phone on ebay and it was on Oreo when I got it and I can't downgrade. Please, I had a rooted SM-J327P and it was cool but this phone has way better specs. I didn't get to do some things on that phone because it got stuck in a boot loop and I couldn't fix it. My software version is G950USQS3CRE2. I know it will be difficult but I was told that it's impossible to stop a hacker by a family member who is good at programming. I can't take people being defeatist saying "It's impossible." If my dad who's good at programming says it's possible, then it's possible.
No one replying
Why has no one replied yet? Is it because people just started working on the exploit when they saw my post so it's not finished yet or are people just ignoring me? I hope it's the first one because I don't like to be ignored. I might be able to give suggestions as to what the exploit could look like. Here's one. We could try to bypass the fuse checks like with hekate on the Nintendo switch.
Respectfully, search the forums. There is as of yet no way to root Oreo but the devs are working on it. And please have a bit more respect for those who spend countless hours working on it who'll make it available to you FOR FREE. Do what I did and make a donation out of your appreciation. Perhaps if they charged for root methods, you would have a bit of a different tone.

The root method was patched there is no root past rev 2 bootloader and more than likely wont be. If you want root get a root friendly device.

Question Anybody have any clue as to how one would go about unlocking A536W or other models' locked bootloaders?

I've tried looking around online and whatnot and have asked many people (even going as far as to email Samsung's team in hopes they might help out somehow) but I always end up back at square one. I genuinely doubt that it's impossible, but I don't know where else to go or what else to do. Does anybody know of a device with a similar situation that I might be able to work a method off of? Perhaps another Samsung device previously thought of to be "impossible to unlock" that I may learn something from? I'd really love to be able to unlock and root and flash this device, as its hardware is quite nice and fast: it's just unfortunate that it gets stuck with OneUI (I know everyone has different opinions on the matter, but I just really don't like Samsung's OS, personally).
Any help or guidance or advice - no matter how small - will be greatly appreciated. Thank you in advance.
you are not having the able to unlock the locked phone that has locked bootloader because they don't wnat you to unlock your phone

Realme RMX2155 was previously thought to be not unlockable for awhile but somebody ended up cracking it via editing firmware files via hexeditor and some other stuff. Eventually, somebody found an even easier exploit. It's not quite the same as the A53, which is why I'm asking if anybody has any ideas. Tons of unofficial methods exist for different models - some easier and some more difficult. If everybody thought that an official method had to be the only way, I'm near-certain XDA forums would be mostly dead with only a few device-forums active.
I've asked on here previously about unlocking the bootloader for my A536U, but it really went to dead ends. The best asset to cracking these devices is time. Just be patient, someone may find an exploit soon.
Although, finding an exploit has been done for phones, I read years ago that someone who did that for one only got it by chance. Its not easy.
Anyone however can sell it or trade it in and buy a device that's unlockable. Much easier.
