On rooted Samsung SM-J710FN, camera & other hardware don’t work - Samsung Galaxy J7 Questions & Answers

I’ve recently been trying to root my Samsung SM-J710FN. I managed to find a sequence of actions that consistently produces a rooted phone. I found TWRP 3.0.2 (I know that later versions exist, but this is the latest I could find for this model) and flashed it using Odin. I then use it to wipe the data partition (because, apparently, TWRP doesn’t work well with encryption). I use adb push to copy SuperSU 2.79 (downloaded from here) and no-verity-opt-encrypt-6.0 (in accordance with instructions in this thread, downloaded from here) to /data, then I install both of them using TWRP and reboot.
While the phone does appear rooted, it does end up having some serious problems. Here are some that I managed to find:
The camera doesn’t work. When I try to start the Camera app, it just crashes after a few moments.
The flashlight doesn’t work. When I try to turn it on using the button in the quick settings panel at the top, I get a message saying that the Camera app is using the flashlight (and the flashlight doesn’t turn on, obviously).
The phone does not automatically change orientation as I rotate it (in apps that are supposed to support it, such as Google Chrome), even though the appropriate settings are enabled.
The brightness controls do not affect the screen’s brightness in any way.
(I also can’t manage to re-encrypt the phone after rooting it, but that’s probably better left for a different thread.)
Has anyone else encountered similar problems? What can I do to solve them?

Have you tried to reflash stock ROM again?

I have. In fact, I did so many times before I figured out the exact steps to successfully root the phone (and then a number of times more while troubleshooting these issues). Everything works fine after restoring (unrooted) stock firmware, but stops working again after rooting.

I finally figured it out. Looks like I should have used a different SuperSU version. I repeated the process using SuperSU v2.82 SR5 and the problems stopped.
(I’m still trying to get the phone to be both rooted and encrypted, but that’s a separate story…)
EDIT: I gave up on SuperSU and used Magisk instead. It’s much easier and seems to work perfectly even with encryption!

Can you give me link to download a Android system and Magisk. Which one you used. I have the same problem :c

Here’s Magisk: https://forum.xda-developers.com/apps/magisk
As for “Android system”, do you mean stock firmware? In that case, I’m really sorry but I haven’t really kept a link to the place I downloaded it from Besides, you need stock firmware that matches your specific phone (based on the part of the world where you bought the phone, I think? I’m not quite sure), which may not be the same as mine.

I've already done it, I downloaded all the necessary files from sammobile.com
But thank you for your willingness to help

As I said before, unfortunately, I have not kept a link to the stock firmware. Further, judging by your other posts, you don’t seem to have a device of the same model as mine (I have SM-J710FN, you said you have SM-J710GN), which means my stock firmware isn’t going to be useful to you anyway.

[Q] New SCH-i535/d2vzw - Undocumented hardware change prevents installing custom ROM?

Apologize if I am posting in the wrong spot, but I have pretty much defined insanity by trying the same over and over and expecting a different result. I have accepted that I can't get it to work, but I am hoping someone can shed some light... and yes I have scoured XDA and the entire net for a solution. Here is my situation:
Received a replacement d2vzw with 4.1.2 because I bricked mine trying to downgrade from 4.3 - in the early days of release before it was known this was a very bad idea.
I am able to root and install custom recovery just fine, but TWRP and CWM cannot see/mount internal or external storage. Philz can see the storage but any attempt to apply a custom ROM fails and increments the binary counter.
I have tried editing the ROM script file to remove the model check but it still fails.
It seems that others have had the mounting problems per http://forum.xda-developers.com/showthread.php?t=2391616, but these are for Sprint and do not work for d2vzw.
From what I can tell it appears Sammy and/or Vzw made an undocumented change in the newer S3's that added additional security to prevent flashing custom ROM's. My question is has anyone been able to solve this for the d2vzw?
Thanks in advance.
Solved
So thanks to the post by ohlin5 here, many hours of frustration have been solved.
Again, my issues were that I could not mount internal or SD storage after apparently successfully achieving root and unlocking via CASUAL. Neither TWRP or CwM would work. Philz would mount the storage, but anything other than stock ROM would not install and would increment the binary counter. Based on other posts I was under the impression that there had been a hardware change (this is a newer S3), that was causing this behavior. However, it occurred to me that the bootloader was not actually fully unlocked (even tho it appeared that way and recovery was able to be installed). Per the posting above, it was suggested to run EZ-Unlock and then install recovery and this WORKED! I am not sure what the issue is and why CASUAL is not working in some cases, but I can confirm the behavior and fix.
Hopefully ohlin5's post can save some others the time/hassle as it seems many have the same problem.

[ROM] Tab 3 7.0 SM-T210/R Stock 4.4.2 KitKat Update

This is the stock US KitKat ROM for The Galaxy Tab 3 7" Tablet. Finally found it after a bunch of hassle online, and figured I'd post it here to make things easier for everyone.
When I Odin'd this ROM, it actually upgraded my tablet, and left all my items installed (not guaranteeing this will work the same for everyone else).
Afterwards, I just Odin'd TWRP to reroot using Chainfire's SuperSU (no other Superuser would work) and called it good.
Caution: if you are using a custom ROM, this may not work without reflashing stock 4.1.2 since the 4.4.2 ROM appears to be an update, rather than a full ROM.
Rooted devices and custom kernels that are otherwise stock should be fine.
The cache, and if possible dalvik-cache should be cleared before flashing. Some of those files can sometimes interfere with upgrades.
It might be necessary to pinpoint apps that are force closing, uninstall and reinstall them. Some apps, particularly paid apps, store their data differently on KitKat, and will automatically fail as a result.
If that fails, it might be necessary to factory reset the device.
The Stock 4.1.2 ROM for the T210R is available here: http://forum.xda-developers.com/gal...-stock-sm-t210r-4-1-2-jellybean-odin-t2958676
The T210R...XAR file is for the 210R:
https://drive.google.com/open?id=0B2iEgzRTFjrQTmI0ZjRBbWtOajQ&authuser=0
The ITV file is for the T210 (no R)
To download these ROMs, a torrent client is required (such as utorrent).
Anyone who wishes to contribute, please seed if you can after downloading ("Force Starting" the torrent will seed it indefinitely.)

I've seen both devices referenced together quite regularly, implying that they use the same ROM.
http://www.boeboer.com/samsung-galaxy-tab-3-7-sm-t210r-manual-guide-wifi/
And even use the same kernel from what I've read:
http://forum.xda-developers.com/showthread.php?t=2439564
I would take standard precautions, such as having a odin image of your original software available and performing a backup of your current system (if able).
Perhaps someone else has some insight to this question?
edit: Looks like I had my information wrong. Found where I obtained the ROM from, it is for the T210R model, and was not intended for the T210.
There are custom ROMs that have been patched for use on both devices, which is where my confusion came from, but this is an official ROM.
I have gotten my hands on the T210(no R) ROM file, and have update the Links above.
I am not responsible for any failed attempts at flashing to either device.

First, thanks for this. I have the T210R. I tried using this and had the same result, it updated the tablet instead of loading a completely new version. I did however run into a problem...the tablet had many for closes and reboots to a point it was unusable and so I reverted back to my backup. Did you see this? Maybe I had a bad download?

I did not have this problem, but I didn't have much on my Tab either. (Some apps don't play well with KitKat upgrades.)
Torrents have multiple segmented hashchecks to make sure you get an uncorrupted download, but it might still be possible. I'm reasonably sure my file is OK since I've used it (can't speak for the non R file though).
Did you clear your cache, and if possible your dalvik cache? I've read that some of those files interfere with upgrades.
If you can pinpoint the apps that are force closing, uninstall and reinstall them. Some apps, particularly paid apps, store their data differently on KitKat, and will automatically fail as a result.
Other option would be to try a factory reset and see if that fixes it. (I understand not wanting to do that though.)
One more thing, if your ROM isn't stock, or stock rooted (custom kernel should be ok too), you may have to flash 4.2 before the 4.4 ROM will work on the device.
Right guys, here i go, just joined and first question!!!
i have not ever rooted a sm-t210 but it was rooted when i bought it second hand!
i have linux installed on my p.c. and was wondering if there is a way to upgrade to and official KITKAT!
as stated i am having problems because my SM-T210 wifi only! and want to update to kitkat official release!
but was hoping also that there is a way/method to root via LINX and not via windows!!
if that is not possible how do i go about it on windows!! as i can use a friends WINDOWS-P.C. if i must!
ah also my SM-T210 does not have the options to change the function of the USB-function,,,
i.e.
it used to have an option to,, use as a mass storege, media transfer or use with samsung keis,,, or some thing of the sort
but this option has dissapeared! may have been my fault!!!! as i uninstalled some system apps,
now it crashes and reboots whenever i try to turn of USB-DEBUGGING options in DEVELOPER-OPTIONS !!!!

Just to triple check, by the above quote you mean that if my tablet is currently rooted, I should still be fine to flash this update correct? [obviously it would become non-rooted once flashed and I'd have to re-root it as you mentioned you rooted after installing]
Also, how much space does this take up?
thanks

That is correct. I was rooted running the Werewolf custom OC kernel. I still had my tablet upgrade without wiping, and one other user has reported back saying the same. But I can not promise upgrade as opposed to overwrite.
The flash file once extracted, is about 1.4 GB, I don't know sizes beyond that. It does not repartition the tablet however.

Could you upload the T210 ITV file? This torrent is going to take 10 hours
No system file
Well this is awesome, system won't mount and I don't have a backup. Samsung website does NOT have the stock firmware, and attempting to get it for another country just to get this to load so I can flash a ROM leaves me with having to download at 15kbs. I am in the process of selling this to someone for their kid... And there are ZERO seeders for these files. Lovely.
Sorry, m'y post an error

For some (unknown) reason, Odin3 nor JOdin3 doesn't seem to work for flashing my Samsung Galaxy Tab3 device. For that reason I tried Heimdall-Frontend, but to make that work you need to extract the content of a stock ROM first.
Anyways, it still didn't lead to get my device into factory reset yet.
But that's another story on which I still have not yet found the answers needed to get the device successfully back into factory reset.
My guess is that the 'system.img' file, of Android 4.4.2, successfully has been loaded from Heimdall-Frontend, yet by going into reboot right away after Heimdall-Frontend releases the connected device, the download may be deleted.
I read that the cause of that may lie in the fact that Android 4.4.2 is only an update and no full ROM.

D801 TWRP Issue - Bottom portion of touch screen doesn't respond

tl;dr - TWRP touch screen won't work after installing custom ROM, much hassle to unbrick, looking for a "bumped" (still not actually sure what that term means) or otherwise modified version of TWRP that won't go haywire when installing a custom ROM.
tl;dr 2 - Also interested in the LATEST "stock-based" ROM recommendations anyone may have... G3 backports or whatever. She needs her Camera to work well but older 4.4.x and 5.0.x OS is missing a lot of new functionality and compatibility with new apps.
I'll just start out by saying that I've figured out just about every way to brick and subsequently un-brick this device that is feasibly possible, and am considering starting a thread specific to those various methods... but that's not what this is for.
This is an issue I've encountered a few times now, definitely on my girlfriend's T-Mobile LG G2 D801 with Lollipop (30B and now again on D801 30C), and iirc, also on KitKat.
I'll explain what I can remember, most of this has been done in the middle of the night after many frustrating hours of attempting various methods... I have to say, this phone has been much more difficult to mod compared to my previous experiences with Samsung and Nexus devices.
I had gotten this device all the way through to CM12 or 13 a year or so ago but recent issues made us decide to attempt to revert back to a Stock-based ROM.
Steps:
1. Root (ioroot / Autorec, can't remember which or for what reason, I have multiple versions of each)
2. Install TWRP Custom Recovery (most recently and successfully using a modified version of the "30B Freedom Tool", although I haven't tried that on 30C - yet.
3. Transfer custom ROM & Kernel to SDCard.
4. Boot into TWRP and install custom ROM & Kernel - most recently GoogleEdition 1.5 and then DorimanX 12.0 Kernel
5. Clear Cache / DALVIK Cache.
6. Reboot device. This is where the trouble begins...
Results: Won't boot into OS at all, instead I end up at the text-based "fastboot" screen, which after multiple tries I can eventually get back into TWRP or into Download Mode.
Once in TWRP after installing custom ROM, the bottom ~1" of the screen won't respond and all other touches aren't accurate... playing with it, I can usually eventually get into some of the TWRP screens, but for most purposes it's about useless.
I managed to restore a backup of the original 30B system image via command line over MTP using ADP TWRP commands, but that bricked the phone in an entirely separate manner where I couldn't access Recovery anymore and the system wouldn't boot at all... I ended up using the LG Update tool to get it up to 30C, and was surprised to find that it still had the restored backup data (apps, pictures, settings, etc), and the phone is now working again, albeit back to stock recovery.
Now, as I mentioned, this isn't the first time I've run into this "phantom touch" issue in TWRP on this device, although the circumstances seem to be a little backwards this time vs when I was taking the device over to CM12/13. I think I remember something about a "bumped" or otherwise modified version of TWRP being out there, but I can't find it now or put my finger on what the changes were.
Has anyone else run into this? I am hoping I've just overlooked something, but days of digging through threads hasn't turned up much.
/edit/ To give you an idea, attached is the folder I've got files stored in... with tons more in Archive and Stock-Based... I've used them ALL at some point. I'd like to get enough info in here to write a Step by Step guide for new owners who are picking these devices up on the cheap, and would appreciate if anyone wants to help out with this!

Consideration and Steps to root

Hi Everyone,
Honor View 10 is going to be launched soon in my country (this end of month). I have considered it as my next phone upgrade. Before, I have looked upon N*k** 8, but that subforum is dead already (no UBL, no root, nothing to see). I am currently waiting for X***mi RN5P which still have no news about the official launch here (probably another 3 months). But they decided to do some twist, by disabling the UBL ability for the phones they launched officially here. Kinda ironic.
To make sure I can live with the phone as it, I have to confirm several things first :
1. Does the phone has native VoLTE that works out of box without installing any additional app? I read from several thread here, it has support Dual VoLTE, but still doubt. I have checked some other phone who said they support VoLTE but in reality doesn't work. My main carrier used to be CDMA carrier, which has completely moved to 4G (only). So we can only call/sms thru VoLTE. If someone can post the screenshot of the VoLTE call setting, or "Enhanced HD" setting or similar, it will be a great confirmation. (I don't need the video call, only voice call/sms).
2. I am using Automagic (tasker alternative). I am quite active in that forum for several months. From there, I read a lot of incompatibility or something won't work, mostly from Huawei Devices. It seem the aggressive battery saving from the ROM has been disrupting Automagic from running properly. Is there anyone here who use Automagic/Tasker or similar automation app and found problem specific for Huawei devices, specificly for this View 10? (using stock ROM). I mean something like wifi scanning or location which work in Phone A or Phone B using the same android oreo 8.0; but doesn't work in View 10. If only minor problem, I can accept it.
3. Is there anyone having problem with the UBL process? X***mi just pull it tricks by kinda banning all user from my country to unlock the Bootloader. (error 86023:hardwareID) I am afraid of the same, as I need root. But I don't need to change the ROM.
Best case
If all the problems are solved and I have bought the device; I am going to root and install TWRP as usual. But I will stay on Stock ROM, most custom ROM still have problem with VoLTE. I might use LineAge or AOSP-ish ROM if there is any and has solved most bug. This is the step that I am going to do after I bought the phone.
1. Unlock the bootloader. https://forum.xda-developers.com/honor-view-10/how-to/honor-view-10-bootloader-unlock-t3749426 Result : Bootloader Unlocked
2. Install Magisk (latest is 16.2) via fastboot https://forum.xda-developers.com/ho...agisk-root-honor-view-10-mate-10-pro-t3749280 Result : Root achieved, Magisk Installed
3. Then proceed on to backup the original recovery https://forum.xda-developers.com/showpost.php?p=75630973&postcount=3 Result : Original recovery backed up. I am thinking to do additional backup by using partition backups, but don't know if it works.
4. Flash Official TWRP https://forum.xda-developers.com/ho...recovery-twrp-3-2-1-0-touch-recovery-t3752397 Result : recovery changed to TWRP.
5. Backup all available partition. Result : all partition backed up, except /data. Since FBE still won't work
After the ritual, the phone will be rooted, Magisk installed, TWRP, and have full backup of all backup-able partition from TWRP and the original recovery. Xposed still won't work, so need to find alternative in Xposed. I mostly use Gravity box and App Settings Modules. Maybe there are alternatives available in Magisk. (haven't research much about it). To backup app's data, the only choice is Titanium Backup then, since /data partition can't be backed up in TWRP. We don't have stock firmware yet available, so need to be careful with the modification.
Do I miss something in my steps above?
Thanks for the answer in advance. And sorry for the long post.
Regards,
Desmanto

How to properly flash tulip with twrp and ota on stock?

Hello there.
I'm using tulip for few months now. One of first things that I've done, have been unlocking device, rooting it and put stock rom with root access on it. So far, so good. I did not encounter any serious glitches etc, but now I would like to finally upgrade miui to 11 (currently having 10.3).
And there's my problem. I would love to dodge making clean installation (wipe data etc) and I do not wish to risk to bootlooping my phone. I've read on some threads (older ones, but still) that you cannot simply install ota update in system, because due to changed recovery (I do have TWRP instead of fabric one) you will cause bootloop. I've tried alternative method of installing zip BY twrp, but program says, that it encounter a problem called "package expects build fingerprint (...) of tulip 0/PKQ1.180904.001/V10.3.2.0.PEKMIXM or PKQ1.180804.001/V11.0.2.0; this device has omni_tulip/tulip:8.1.0/OPM8.181105.002/1", and then sait, that in had error 7.
Is it simply wrong rom being installed and I have to choose something that is being named the same way and supports ota, or is there a way to go more swiftly through this process? If so and I should pick rom with ota - what to choose? I like deep level customisation, but compatibility with google store, being able to use store, payments and paid apps, instead of "opening them" by some lucky patchers kind of apps.
OR MAYBE I just need to change recovery from TWRP to something different - like PBRP f.e.? Just like this thread says - https://forum.xda-developers.com/re...how-to-setup-official-miui-breeaking-t3893703
Just a quick update - changing twrp to pbrp does not change anything in upgrade process - still get the same error, now just without telling me, which version do I have.
Also, what's interesting, apparently twrp said to me that I do have android 8.1, but "about phone" in system says, that its android 9 (9PKQ1.180904.001 to be exact).
That's werid, because everywhere I check, phone says "android 9" as a version of it.
Have you tried wiping system and installing?

Not yet. I've found method of flashing via PBRB with usage of downloaded file and one option check, but I'm not gonna try it, unless I do a backup of my apps. If that won't work, I'll perform a clean instalation and choose rom that supports ota.
well, I've tried to do this with the method, that I've described before, but this did not ended successfully. I'll look for rom with ota update possibility and then install it most likely. Apps had backup, so I lost almost nothing.
It worked. I had to download bigger patch (1.7 GB, instead of circa 700 MB, that I've tried before), I also had to use method described here -> https://c.mi.com/thread-1782169-1-1.html (pitch black recovery, instead of twrp + one tweak in options). Start after flash was very long (it took like 10 minutes or so), but it booted successfully in the end. Not sure which rom I do have after all, but as far as I remember it was so close to stock, as possible (with only few extra options and tweaks). So yea, it just works.
