Development for SD820 with an unlocked bootloader? - Samsung Galaxy S7 Edge Questions and Answers

Hi! Due to the locked bootloader of the SD820 variants stateside there has been no development for the devices so far. However the Asian versions of the phone also feature the SD820 but come with an unlockable bootloader. Thus far there has been no root/recovery install method in english and the one exploit by the chinese developer Xiao1u has reported to have caused problems with performance and the camera.
Are any developers on this forum able to work on development for the Asian versions in the form of recoveries/roms etc?
As far as I understand it any development for the Asian devices would benefit the US variants once an exploit is uncovered, however I understand that lack of physical devices in the hands of developers is a roadblock.

Not a dev but it is interesting to see the differences between regions of the same device. I wonder if the rooting and custom rom/flashing culture in Asia is more or less popular than western countries. Hopefully it will help is find an exploit for the locked 820s.

They are pretty active but the majority of it is done in chinese (for obvious reasons) leading to limited international exposure. However the devs are undoubtedly talented with many root exploits being discovered by them for devices before western devs.

Roms for Rogers? Not just Rogers Roms

So yes I know we've only recently been able to root our Rogers Dream/Magic
When will there be roms canadians? All I see are Roms that are for the T-Mob and even Rogers Roms ported to the T-Mob G1
is there any progress in modifying/creating roms for us?
I'd love to see some roms like the Ion, Dudes, JF, Cyanogen, or does it already exist? (didn't say hero cuz i've heard the dream can't really handle it or it's not ready)
because i've been sweeping thru the forums daily for canadian stuff...
Maybe I'm just blind?
Thank you in advance
bump, no responses?
There are no ROMS for Rogers yet. Cyanogen tried compiling his ROM using Haykuro's offsets with no luck.
It looks like we're missing a yet undisclosed kernel module that HTC developed. They are legally required to release it under the licensing terms of the Android OS, but nobody has been able to get them to comply yet.
They are not the licensing terms of the android OS, they are the licensing terms of the LINUX KERNEL. This is *much* bigger than just android.
The problem here is, of course, that HTC is not a North American or European entity... being the case, the GPL may not apply to them. It would apply to Rogers though, BUT, unlike tmobile, Rogers has NOT rebranded the device -- its branded HTC, which means that Rogers may not be responsible for enforcing the GPL on it. That, of course, means that the only solution may be at the level of the CANADIAN GOVERNMENT, which can block imports in the event that the device doesn't comply with the law, if that were to happen, then I'm sure HTC would comply with the GPL, but of course, that is not going to happen since it would take years in court, by which time the device will have reached EOL anyways and nothing would happen.
In other words, I wouldn't expect much to come out of this. If anything, it would be more productive to separate the blob from the kernel and patch it to custom kernels as a blob.

[Q] Any hope for G900H Custom Rom ?

I looked around in the forum and I saw many discussions from May - April
about a possibility for a future costume Rom on G900H
Is there any update about it ?

Your selection is very limited and not likely to expand much simply because you have a niche device. There are legions more Qualcomm based S5s in use than Exynos. Which also means that few Developers have the H variant and the natural result is a dearth of 900H custom ROMs.
Any decent search would have found dozens and dozens of threads, asking and answering this question. Not to mention the actual ROMs.

I Have a g900h phone. I understand in most countries in the Americas peoples use this model. This is a high tech phone and perhaps the reason why most developer have qualcomm is only matter of coincidence.

You are mistaken. Most countries in the Americas use Qualcomm models e.g.
Canada 900W8
US 900T, 900A, 900V, 900R4, 900P, 900W8, et cetera
Mexico 900M
Brazil 900M
Chile 900M
Columbia 900M
Argentina 900H
In the list above, all of the models are Qualcomm except for Argentina. Only a few South American countries use the Exynos 900H. Since the vast majority of S5 phones in use are Qualcomm based, most developers also own Qualcomm phones as well. And that is the reason why there isn't much 900H custom development.
.
FWIW, Venezuela apparently uses the 900H as well.

How are they going to brick their phone? With the locked bootloader and no root, there is no recovery to flash anything.
Trying to flash any sort CF Root or custom recovery will indeed brick a Note 4 CE

KennyG123 I appreciate what you are saying but I need to disagree with the notion that there is not a need to provide a distinction between threads that focus on mods for the retail versions of the Note 4 and those that focus on the Developer Edition of the Note 4. As you know, the Retail version and the Developer Edition of the Note 4 are identical except for one very important element...the bootloader. Mods/hacks etc. designed for one can be very detrimental to the other. They are not compatible in this respect.
I'm sure with your experience and expertise that you have seen many, perhaps hundreds, of inexperienced users, excited about taking advantage of their new Android phone and its potential for modding, do something that bricks their phone because they simply didn't know better. Distinguishing threads intended for Developer Edition phones is not intended to benefit the knowledgeable "crack flasher", developer, coder or themer, it is intended to help the "noob" or less experience user from doing something that will brick their phone or lock their bootloader.
With recovery and root now available for the Developer Edition Note 4 ROMs are not far behind. And, hopefully root and SafeStrap will be available for the retail version soon. With that/those events, the ability for new/inexperienced users (both retail owners and developer edition owners) to separate what's safe to flash and what isn't is going to get very complicated. This is only going to be compounded as OTAs begin to be released and different version of firmware start to show up for users to flash. Having a way to separate or distinguish threads intended for Retail users only or Developer Edition users only makes sense to me. Just saying. No rant intended. Thank you for listening.

The only threads that need warnings are those for root and those for recovery. There has been no issue with the S4, S5 or Note 3 sections. Again without recovery nothing will flash and no harm can come to the phones. They are exactly the same devices, just bootloader unlocked. People desperate to root will try anything in spite of the warnings. As far as I have seen on previous devices attempts to install recovery will fail and worse that happened was they had to Odin in Stock tar. As I said, unlocked developers editions are not new. They have been in use for Sammy Verizon for almost 2 years with no need for a separate section. If anything the locked edition should be confined to General and Q&A. With so many variants of the same device people will always use the wrong thing. No amount of warnings has ever stopped that. Read through the Sprint S3 sections and find all the bricks caused by flashing international ROMs. Both sections have warnings posted clearly. So we really don't need "the sky is falling" kind of thing here. We just need people to read. The information is there.

Thanks KennyG123 for your response. I totally concur, reading and researching what you have and what you want to do is the first step for any user. I came to the Note 4 from the DE5 and thankfully when ROMs started to appear the developer or OPs did specify whether the ROM was for retail or DE users. I hope this will be true for the Note 4.

Unfortunately this lock down of Verizon and AT&T devices has killed development since the S4. This is the other thing to think about... If someone does crack the bootloader or finds a root and SafeStrap like method, suddenly all the DE ROMs will be usable by all.

I don't post much here as I usually find my answers with a little searching, but I'm a daily lurker and have been since the days of OG droid. I strongly disagree with your statement. There has indeed been plenty of confusion in the Note 3 threads. Also a good little bit of drama and some anger over poorly marked threads. Yes, the threads should be more clearly marked "Developer Edition" by the OP, but it doesn't always happen. In the end, I think it just makes more work for you to moderate but that's your choice.

Well, you'd think so, but (in the case of the S5 anyway) the number of ROMs available for the retail version out number the number available for the developer edition. You'd think that it would be the other way around. Most developers aren't releasing two versions, one for retail (SafeStrap) and one for DEs. As of last week anyway. Either way, development for the S5, either model, is pretty slim. And, the unified ROMs (AOSP) just don't seem to be ready for prime time. There is always something that just doesn't work right or not at all.
But I have faith. I hope the Note 4 will be blessed with a multitude of ROMs to accommodate a wide range of user wishes and desires...besides it's getting close to Christmas, gotta have faith, right?

That is because so few of the DE's were sold.
Adding more forums only adds to the risk of someone flashing the wrong thing. Better they see threads like this than assuming all Verizon variants are the same. There are many other variants that have no forums, US Cellular, Metro, Boost, some Chinese knock off... It is ludicrous to make a separate section for every one. Developers have usually been good about properly marking their work.
If people don't read the documentation then the only person at fault is themselves.

New to S7... Why are there only 3 roms posted here?

Is there something I'm missing?
Sammy locked the Bootloader
Yup. This is the most highly sought after device with almost no developer support.
If you wanted root then you should get pretty much any other phone.
if you change the Android Code, you have to share it.

Correct me if I am wrong, but according to the Android Platform User Agreement (I think), if you change the Android Code, you have to share it. Or some form of developers open source agreement. Correct?
So there has been no root accomplished whatsoever on the T-Mobile S7? If that's true, then I'm hanging on to my Note 7 and selling the S7E.

I suppose you really need to read a bit more.
For all Qualcomm US devices the bootloader is LOCKED.
This is well known and documented. Root is possible only with an engineering kernel. The page that you referenced is inaccurate as it referenced an engineering bootloader. It's actually an engineering boot.img file that the writer mistook for a bootloader. Again... it's an engineering kernel not engineering bootloader.

But arn't there other S7 roms from Verizon, AT&T and Sprint having developers pushing out custom kernels? Is this something that T-mobile can release but won't?
Google gives/updates the OS, Samsung gives the S7 hardware / Updated OS - Patches the OS & then gives to the Carriers (Tmobile) and they plug in their hellware (Bloatware), surely they have the source or the ability to modify the stock rom when updates are being pushed out to the carriers.
When a New Stock drops, it is the phone carriers who modify the kernel's, boot animation, build property, and sets their modems and such . . . Not Samsung because they would not be want to push out the kernels, modems, build property, boot animation & custom roms for each phone carrier in each region of each county. So lf what I am thinking that our phone carriers developers are lame ducks....
Going the other way on this, how does Sam Mobile play into this? how is it that they are able to host the roms on their servers? Arn't there any links from Samsung to host the roms?
Please if I am wrong, please someone correct me.
It's complicated...
Samsung locked the bootloaders on all US (Qualcomm) S7 but left the bootloader unlocked on international (Exynos) roms and some international Qualcomm roms.
This sucks and hopefully is not repeated on the upcoming S8 which may be Qualcomm only.
Last summer, an engineering bootloader was leaked and a group of people here got a root that uses the engineering bootloader. It's not perfect, as it forces people to use a non-production kernel. More people here came up with settings to get the most out of that kernel.
Right now we are in the middle of the transition to Android 7 and the engineering root doesn't work with it presently. Until a solution for that is reached
At the same time, the international rom deveopment has gone smoothly with over a dozen roms updated and a few tweaked kernels. The Exynos phone itself seems to be faster and with better battery life (but worse reception) compared to a standard qualcomm. Rooted with a custom kernel on both, it's like night and day how much better the exynos performance is. Some people ported T-mobile wifi calling and Volte (through CSC settings) to the international version, so for a certain user (of which I am one), the ideal root solution is to run a full speed exynos 930F on Android 7 and retain t-mobile functionality.

I was dead set on getting the Note 7 but after the fiasco i settled for the S7 edge. the G935F also has all the bands that t-Mobiel uses so we get band 12 as well. The issue with getting the G935F is trying to buy online as it has to be imported and still get insurance and so forth. Bought from B&H photo ( aa reputable US store) for insurance and good support. The g935F turned out to be a good gamble. As long as you wait there was alot of development. Since alot of us T-Mobile guys hopped over we were able to get Volte and wificalling ported over via various CSC edits and other workarounds. So we get alot of custom roms and T-Mobile support as well. Only issue you have to root and loose Samsung pay but for me that a okay lol.

Is any customizability permanently lost in OTA nougat update/ security patches?

Hi brand new to S7 edge (SM-G935T). Love this phone so far but would like to update to nougat and security patches ASAP as i had my last phone hacked and want to minimize that chance.
I have rooted/s-off/etc and played with custom ROMs, boot screens and animations, etc for MyTouch 4G Slide years ago.
After that i had some limitations modding a Galaxy S4.
I know sometimes system updates would lock you out of some levels of customization of the system.
So i'm wondering: will any of the OTA updates will lose me something i can't get back?
Thanks in advance
Well i think i can answer this myself now for any of my fellow befuddled would-be buyers.

So if you bought any of the US carrier models with the snapdragon chip you probably might as well take the OTAs to the last security update (Here is t-mobile's list of releases) for updates and security purposes, and then play with that release and decide if you would prefer to flash to the brandless ROM "G935u" instead of "G935t", which won't come with the carrier's cruft. To specifically answer my OP question, it's still possible to root the latest version of them, for what it's worth, although not GOOD methods.
Sad face. I was beguiled by the xda-developers Samsung Galaxy S7 Edge page into buying the S7 Edge without realizing a lot (all?) of the cool stuff was for the exynos variant.
With the way things are now in the mobile world one should not put his faith in any one website. Most snap dragon chips come locked tight this day in age. My self included should have done much more research in before buying.... I'm am at least thankful for root.
