I have questions about Samsung Galaxy J series, specifically the J3 Virgin Mobile

I have a few questions for anyone familiar with the Samsung Galaxy J series, specifically the J3. I have virgin mobile, and after a long time suffering with their HTC Desire 510, I want to upgrade, and not wanting to spend $400 on a galaxy S5 , the J3 seems the next best phone to get. However, as I've grown used to having a rooted phone and customizing my phone as much as I want, etc, I want to make sure my next phone can be rooted, and has support for custom ROM's, etc.
The main thing that could help me with my decision would be some guidance as to whether other versions, the J2, J5, J7, etc, that are present here would be potentially compatible with the J3, or if I'm out of luck and should consider other options if rooting is a necessity for me.
Any help is greatly appreciated!

Anyone?

I'm sure you can root it.
I'm using j5 and it took me like 15 minutes of reading and about an hour /including downloading and setting up all the things /for the root.
I just want to say that you would need to be prepared to wait until someone make a custom Rom for it.

Thats what I was thinking. I figure that rooting it (hopefully) is similar to the other J series. As long as its rooted, wouldn't I be able to (even w/o custom rom) debloat/customize/etc it with various root tools, apps2sd, etc? Or are those dependent on having a custom rom? On the only phone I've rooted so far (htc desire 510) I didn't really spend any time with stock rom when I rooted, instead immediately flashing Nonsense rom, so I'm not sure what limitations keeping stock rom comes with when rooted.
Thank you for the reply! It gives me a bit of hope at least.

I'm not really familiar with the device. As I said before I have a j5. According to the applications that you mentioned I think that it would be possible to get and install them. But rooting isn't quantum mechanics. There are some apps that you could easily install on almost any device and get the root privileges. For example kingroot I am sure you can find others. I usually root my devices trough pc.I recommend you to take some time before jumping on the first option that comes up as a possible solution.
According to changing the stock Rom. I don't known how developed is that treat so.. Again read here and there about it.
GL!
Let me know if I helped by hitting the thumb up

I dont think permanent root is going to be possible until a working twrp is made so that you can flash supersu. I know that sux, I wanted to get one for my wife because she broke the screen on her vm s3. But without root and the ability to get unlimited hotspot... nope. I asked a dev ( lrs121) if he would port twrp to it. He said he would try if I had the phone and could get him the necessary files from it. Look in the sprint s3 section under twrp for virgin and boost s3. He is a great dev.

Actually far as I can say there are 2 twrp options. you just have to read more

Read where? Could you be a little more vague?
I am by no means a noob, and when I answer someone, I generally throw in a link.
But thanks for letting me know it exists.
Is it another phones twrp that works? Any hints at all?

Sorry i was on the phone while traveling. I`ve mistaken that it was about the j5 ( like mine device) and for that especially i had tried 2 working options up to now for twrp. but i`m pretty sure you can find tutorials or you can even simply DL the twrp /for example/ 3 install it as an apk and than you if it stuck just would need to DL odin for your PC and than strictly follow the steps / install /unzip odin, connect device , go into DL mode and flash it with the stock ROM which you can find in sammobile /.com i guess/ ?
GL and hit thanks if i helped!

Dual boot or multi rom?

Hello, I was searching the forum and Google and didn't really find much.
I was wondering if the S7E had the ability to dual boot Roms? The goal for me is to have a N7 port on another slot than my standard rom that I'm running. I have a 935F.
Any help on this would be appreciated.

+1....but i don't think will have such thing thanks to exynos chip
- tapatalked - from my VANTABLACK S7 EDGE

Yeah, I was thinking the same thing. I recall being able to do it on my Nexus. I also believe my s5 had the option. It's been awhile though.

me too i had this on my nexus 5.zperia z2 and even xiaomi redmi note 3 Pro but they all have in common a Qualcomm snapdragon chips
- tapatalked - from my VANTABLACK S7 EDGE

Yeah, too bad you can't do anything with the snapdragon on the S7E. I started out with a snapdragon, got so angry with it and traded it out for the 935F.

i have the exynos chip but what's wrong with SD chip
- tapatalked - from my VANTABLACK S7 EDGE

I also have exynos now. Nothing was "wrong" with it. I had a locked bootloader which limited the things I wanted to do. Trying to make Roms work the way I wanted was a PITA. Hence why I switched.

Dual boot is possible with Dual Boot Patcher on note 5 which I had before S7E , so that means it is possible for exynos chips but I don't know if our S7E is compatible with this app, as I decided not to root this time .

I'll test it out now and report back.
Thanks for the find!
Update: As of right now I cannot get it working. I get it to say "Switching rom" and then the rom stays the same. I will continue testing.

So, I tested it out and I was not able to get it to work. My initial problem was that aroma installers were not supported. I tried both TWRP and in app flashing. The error logs stated it failed to update the binary. I'm not a dev, nor do I pretend to be one so I have no idea how to fix that.

To get it working our device model must be supported and on the list of supported devices included in the app which I guess is not but is possible with some dev help.

It is on the list of supported devices actually. That's why I was hopeful. Everything goes like it should, but when you switch to the rom nothing happens. Or you get it to say "Switched roms" and you are on the same rom. The dir isn't populated with the boot.img either so you can't manually flash it.

Could be. I just updated my BL and CP, so I'm going to test again and see how it goes. I'm not aware of any 935F kernels that support dual boot though.

When I had the note 5 N920c some roms were successfully booting as a secondary rom and some perhaps most didn't because of twrp recovery, but there were moded twrps which solved these problems.
As I decided not to root then I don't know if there's a work around for S7E or not.

Thanks for the info. I'll probably keep testing and see what I get.

dave7802, Sorry from being new... but can you explain your statement? I'm an iphone user that is looking to switch to android, and I'm thinking of buying an S7 Edge. I want to be able to dual boot it. Sounds like you were able to get it working, but would you be able to help me understand how? Sorry totally new to this whole idea of ROMs and dual booting. I just want to make sure the phone I'm about to buy is going to be able to be dual-booted. I'm in North America, and I read on a different thread that the NA phones are not BL unlocked.. is that going to be a problem?
Sorry to ask so many wide open questions, but you are the first person that I have seen to confirm dual booting of an S7 Edge.

It will depend if its EXYNOS
If so you should be okay, If its Snapdragon then its locked and there is limited support.
The dual booter Patcher app, Bascailly allows you to installed selected ROM's in the Internal or External Memory.
And from within the App you select your Current ROM, Upon restarting the device will boot into the addtional ROM.
Now chenxiaolong is updating to Support android 7.0 And the dual booting is newly supported for the S7 Edge so it may be some time before its perfect
But keep in mind that the Root method Magisk is also bringing a Universal Dual boot so this may be another option.
CM builds are not yet created for this device, So it is only Stock ROMS you can dial boot

Thanks this is really helpful. Based on what I found online about the Snapdragon distribution, the US 100% snapdragon, so I think I'm going to pass on this brand/model. Any other recommendations for devices? I'm thinking the Google Pixel, or the 1plus3T. They are both really new phones, so I'm guessing they wouldn't be supported. So new to all this, my head is spinning.

Total android noob looking for root help

I was wondering which samsung galaxy s8 should i buy on amazon for rooting since i hear the american verisons have a root but it drains 20% of your battery life.So what if i get a unlocked international version? Would that be the best approach or what exactly should i get?

If your reason to root is to use different roms then you should do some research because my understanding is that most US s8 have locked bootloaders and roms are not an option. I'm not up on all the details, this is ment more as a FYI.

Its to mainly have full control over the device,but i don't want the battery handicap.I asked on a different forum and found out from someone else that in order to not have the battery handicap i have to get a exynos model that has a F instead of a U in the model number and install twrp with magisk.I cant believe you couldn't just tell me that and save me the trouble instead of telling me to do research.
All i need to know now is if a exynos unlocked s8 is ok to get with a root because i am going to want to have a specific sim card working on it

I didn't tell you because I didn't know. And your welcome for even responding. A**hat

Yes exynos version, as you say, rooting itself is easy and painless. I kept mine stock for 2 months but rooted a month ago, and am loving the flexibility and ability to tweak what I want (debloating lotsa bloatware apps, changing bootanimations, trying and managing various kernels and custom ROMs) enjoy!

Worth it to root Sprint s7 Edge at this point?

Hey guys, just looking for some opinions here on whether or not people think it's worth it to root the s7 Edge right now. I just picked one up and it has MM and binary 4 on it, so I figure I need to decide if I want to root it before taking any updates. Does the official oreo seem decent? Is there any way to make touchwiz feel less touchwiz-y without root? Thanks!

I would advise to not update to any build after october 2017 if you plan on switching between carriers other than sprint as sprint is the only carrier to have updated the bootloader to 5 and many seem to believe the others won't. rooting is possible either way.

Thanks, so downgrading the bootloader is not possible once it's been updated even with root? I see on sammobile that there are several 935U firmware versions for sprint that are 7.0 but have binary 4, are these viable options? I do have a gear S3 so i would like to not lose samsung pay/S-Health, that still happens when rooted right?

Correct, once you update to any G935P firmware QJ3 or above you will be stuck unable to install any other firmware and unable to downgrade whatsoever, even with root...Trust me i'm stuck in this particular issue atm as I obtained this parts phone with the sprint motherboard that had QJ3 firmware with the bootloader 5 on it and now am unable to use it on my verizon account leaving me with having to obtain another motherboard. the 935U firmwares are completely viable options, they are just debloated and come without carrier modifications, If you need any assistance with anyting further i'd be glad to help, i don't proclaim to be a pro, but after months of research and trails on the G935P I've learned quite a bit on the do's and don'ts lol.

You are awesome, thank you! Are the roms posted in the general s7 edge section working for the sprint variant? The specific forum for the G935P is very dead. Im just weighing pros and cons of rooting, if there are good roms that improve performance and battery life available and magisk is working I think it'd be worth it to root for me

I would look more into the roms listed under verizon and at&t variants of the S7E, they are more active and most roms are made with multi-carrier support...they will say in the installation guides, but the ones listed in the general forums are mainly for the international versions if i'm not mistaken.
Also, check the forums for the S7 Flat version as they seem to be more active and most of the guides/roms apply to both variants, also confirm that in their respective guides.

I just checked for updates on my SMG930P today and it looks as if Sprint is now binary 6!? Hopefully this is a hint that the rest are moving to binary 5 for Oreo. I'm going to wait on this update just in case. G930PVPU6BRD2 is the latest update that just popped up for me.

I just wanted to verify if I flash G935UUEU4BRD1 Firmware I will still be on binary 4 which will allow me to switch carries and achieve root? Is sammobile the only reputable resource for these firmwares? Seems like they charge a bit much. Thanks guys

[HELP] Buying samsung s8 advice

Hello friends!
I'm considering upgrading to a SGS8 and before making a purchase I need your help confirming what I should look for if I want to have an unlocked bootloader in order to install whatever ROM I please ans be free from Samsung's tyrany.
Please tell me if im wrong or missing something here when looking for one of these on Amazon:
-Model: SM-G950F or SM-G950FD (This is because these models came to the market with the "OEM unlock" option under dev settings and they have an Exynos chip)
-Running stock Android Nougat 7.0
-Bootloader version: ??
Got it right? Thanks for your help!!!!

Nobody here will guarantee anything probably, and neither do I, but I'd say that what you wrote sounds good.
You can send it back within 30 days with Amazon anyway

thanks mate, just looking forward an educated piece of advice from someone versed on the whole story and current dev state about this phone =)
I understand there is a whole bunch of models SM-G9500, SM-G950F, SM-G950FD, SM-G950U, SM-G950U1, SM-G950W, SM-G950N....
Some Snapdragon, some Exynos...
I understand its best to go for an Exynos one, and among those the SM-G950F, SM-G950FD.... perhaps someone can tell me why is that or correct me?

F & FD are same. They use the same firmware.
The only difference is FD version has hybrid sim slot (2 sim or 1 sim + sd card).
Whereas F version has 1 sim + sd card option only.

Definitely go for an exynos version. Go for a G950F/FD. What these people said is correct, FD is dual SIM version. they are unlocked international versions with unlocked bootloaders. There is quite a lot of development ongoing for these devices.
