Why? Hell, the Note 2 is on MM update list & other service provider SM-J320's came with MM..... what is up with Sprint? MM even allows app permission editing without involving root so yeah, reasons for wanting MM are def there!
[Miscellaneous Android Development] johnnyblaze420:
Only two j3 variant came wit 6.0 thats the at@t one and us celluar none of the others came with 6.0 you either have be patient if 6.0 that important to you or develop 6.0 rom for j3 or go buy new phone with 6.0 i personally would like to see a custom rom developed for our phone
[Miscellaneous Android Development] 1000Dead:
Exactly! [emoji2]
[Miscellaneous Android Development] johnnyblaze420:
I have been reading a lil bit about dual boot on phones does anyone know if it wouldbe possible on our phone? Coolbeans that may help you with 6.0 if dual boot is option for us

---------- Post added at 04:43 PM ---------- Previous post was at 04:39 PM ----------

If anyone knows of any roms that may work with our phone or if anyone knows how we go about making custom rom i am more then willing to test an use it i would love to see more development for this phone i think it really decent entry level phone would be so much better if we had our own custom rom

This is a thread for sm-j320p and how to root that device. SM-J320P.
[Miscellaneous Android Development] johnnyblaze420:
This method will work on boost sprint virgin most likely thats it it may work on your phone but thats a gamble only you can make prrsonally if it you everday phone i wouldn't gamble unless you all ready have stock rom specific to your phone and are familiar with using odin its worth try at worse case scenario you have reflash stock rom start fresh as if first day you got it again but definitely not worth gamble if you dont have a pc and stock rom and odin
[Miscellaneous Android Development] coolbeans2016:
Definitely, custom ROM is way to go. I was thinking CM with lollipop due to porting problems with MM, but since this device flys with MM on it already.... CM 13!!!!!

Why I was on this thread asking about this device before purchasing it.... the fact it had TWRP ported for it was the reason I purchased it. I had to use my fingerhut account to get it, costs me $20/month for 8 months.... I was left in a wheelchair from a motorcyle wreck few years ago, woke up in UAB hospital in a body bag, toe tag & all........ so have to pinch me pennies verrrrryyyyy hard, lol! All those years of drift racing, pushing 22+ pounds in turbo and a quick run on a kawasaki did me in, oh well........ workin on it.

With CM 13.1 this device will rock!

[Miscellaneous Android Development] johnnyblaze420:
Any ideas on a way to get a rom working for our phone cm13 is definitely what I wanna see us get im a novice at best relatively new to all this not sure what steps we need to take to get a working custom rom or how we go about developing our own does anyone know what is needed or what steps need to be taken to get a custom rom ourselves

[Miscellaneous Android Development] johnnyblaze420:
Wow yea thats alot of reading an configuring but there are two variants that are pretty close to j3 spec wise that allready have cm rom so maybe if can piggy back of of that build reconfigure things to match up to our probably far fetched may not be possible just spit balling ideas im definitely new to all of this but im gonna continuereading that page see if i can try making one testing it myself if i can comprehend all that has to be done that nothing can be accomplished if no one takes the risk

I have been trying my hardest to root this phone. I have the At&t version running 6.0.1 Samsung still hasn't been able to get me to the right place. AT&T is probably not releasing it so it can't be rooted.

Last night my phone locked up, this is normal i hit reset and went to sleep. I wake up this morning to a large triangle saying Custom binary blocked by FRP I've had my phone rooted for a month now and haven't had this issue before... What the heck happened?

Edit: fixed it. Just reflashed the stock boot image turned FRP back off then reflashed supersu.

[Miscellaneous Android Development] coolbeans2016:
Okay. Understand, my hp laptop was not even portable anymore b4 it died. Had the hood off, usb mouse/keyboard, as it slowly died. Fortunately, caught an open box sale @ BestBuy. One of those quick list notifications, got a new 15.6" HD, i7 with 8gb ram, terabyte drive for $349. Was not booting up, recovered/fixed mbr right there on counter b4 purchasing. Norton utilities offers defraggin boot record, compression tools, got it from 3 minutes and change boot time, to 7 seconds! Fast as an ssd. You want me to get a sh*t list of what/how/when getting Ubuntu up @ running? Need make, model, specs, windows version of urs.... if it does not require being the only os on a machine will prolly load it up on mine as well. Personally, cannot stand sh*tsungs touchwiz & need to cut my teeth in this realm sooner or later......

[Miscellaneous Android Development] 1000Dead:
Installing a Linux os (especially) u Ubuntu is really quite simple. If you know nothing about linux, which I am guessing is the case due to not knowing how to even install it ?then it is going to be a long road to editing/modifying/remaking the kernel for a custom rom on this device. That being said once you guys get Linux up and going use the terminal as much as possible when starting out as it is your best friend. If you are having a lot of trouble dual booting than another option (and not a bad way to go for installation first couple time so nothing is messed up) is using VirtualBox to set up a virtual machine to mess around with. If messing with VirtualBox and having some issues there is sometimes a setting in your bios to enable or disable virtual machines.

Found a quick fix for icons, and can do individual icons, one at a time. Zedge, which I always knew as a site for ringtones, etc.... has an app. Downloaded it, lo & behold has icon packs listed. Browsed down to one I liked, chose the icon for calendar, it showed it on my screen what it would look like & created it. Clicked it and it opened my calendar! Just had to ditch stock icon and put the custom one in its place where I use the shortcut, voila! [emoji41]

Odin

Hi guys,

I'm running the Sprint Variant J32OP and went through the steps. Once Odin says PASS I reboot into recovery but it boots into the stock Android recovery with the options to apply update from ADB or SDcard etc...

Its definitely not booting into TWRP

I followed the steps to the exact. :confused:

Samsung driver downloaded and installed

Used Odin v3.09 and also tried v3.07

Used TWRP recover and tried the Google Mirror .tar

OEM unlock

Any help is much obliged
[Miscellaneous Android Development] 1000Dead:
If I remember correctly to get into twrp you have to do volume up instead of down or vise versa. Hope that helps.

I just got a system update, appears to be a security update only, though there are a couple of added apps I don't recall, still at 5.1.1:

Software Version: J320PVPU1APE1

Android Version: 5.1.1

Android Security Patch Level: 2016-05-01

Baseband Version: J320PVPU1APE1

Kernel Version: 3.10.49-7892928

dpi@SWHD7402 #1

Thu May 10 17:49:29 KST 2016

Build Number: LMY47X.J320PVPU1APE1

Knox Version: KNOX 2.5.1

Unfortunately I hit the ok to update button before attempting to grab the update from cache. If anyone else gets the update, please try to grab a copy of the updated zip before applying.

I have not attempted root on this update, no time this weekend, will see what's what next week.

I feel your pain. I know it sounds redundant but have you checked the md5 on that recovery your flashing? Or maybe even the cable your connecting with. I say that because your passing but somethings not getting to your phone. You sound knowledgeable so I'm sure it has to be something obscure. You can also attempt a adb recovery install thru usb debugging.

It looks like the only added app was Samsung + and a new sprint boot logo, at least, that's all that's noticeable anyway.

[Miscellaneous Android Development] gtibay04:
Hi all, I'm attempting this on a SM-J320Y, it's the Philippines variant. I've OEM unlocked and debug is on, used Kingroot to go into Flashify as well as done Odin method, but I've hit the following snags:

1) TWRP touch doesn't work. I can get into recovery, in fact it gives me a SEANDROID fault and forces me into recovery, but I can't touch anything except the power button which further locks it.

2) I've tried all the CWMs I could find attached to J3, but when I try to go into recovery it just hangs at the Odin Mode stat readout overlay on the main logo screen. Tried all the buttons, doesn't bypass. But it does allow me to boot normally unlike TWRP if I don't opt to enter recovery.

At a bit of a loss here, would appreciate any help. At least it seems like I can unbrick as needed so no problem there and well I've pretty much figured I'm going to be violating warranty no matter what now since my Knox tripped. I mainly need the use of Link2SD as the space is way too limited with all the bloatware Samsung has put in. (Does anyone know if I use KingRoot to temporarily use Link2SD and then restart if the symbolic links keep functioning without root?)

Update: Just attempted to use 2015 J5 SM-J500F TWRP builds as the specs are similar so I thought the port might take. Unsuccessful.
[Miscellaneous Android Development] Curtis1973:
Twrp and root is not universal across the J3 variants. In fact anyone using any variant not J320P should avoid using this here.
[Miscellaneous Android Development] m_444:
Hi , i followed all the steps carefully and still couldn't flash TWRP through Odin i tried both version 3.07 and 3.09 after it says PASS i could not boot into recovery by pressing VOL UP + HOME + POWER BUTTON , i cannot either turn off the phone by holding POWER BUTTON the only working combinaison is VOL DOWN + HOME + POWER BUTTON i get stuck into the ODIN mode and when i pull off the battery and go to recovery i still have the Android system recovery menu , not TWRP if someone could help that would be great .

I have a J3 (SM-J320P) with lollipop 5.1.1

P.S : i tried the without PC method too didnt work :(

I attached some screeshots
[Miscellaneous Android Development] SteveOx1:
Did you turn on OEM unlock through developers menu? For me it was that I was using a 3.0 USB plugin on my PC. The phone didn't recognize it.
[Miscellaneous Android Development] m_444:
Yes OEM unlock is on , plus when i plug in the USB i see the that ODIN has detected it and changed the COM port number

Any chance of begging for some development into J320Y crossover? Anyways, now at least it can be written that this definitely is ineffective on the J320Y variant.
[Miscellaneous Android Development] KUSHLEGEND:
Ive had a similar problem along with a couple others . Everything said it worked but mothing was writtrn to the phone. It ended up being the factory usb cord that came with the phone. You have to use the original cord that came with the phone. Try the odinn method with the OG cable. Hope this helps you

root issue es file explorer

Have obtained permanen root & TWRP's recovery off another thread concerning this SM-J320P. Also experienced no root issue with ES File Explorer, but google searched this yesterday and found this:

https://disqus.com/home/discussion/mjdseo/how_to_enable_root_browsing_in_es_file_explorer/best/

It seems it is not due to slow response by the systemless cfSuperSU, but due to the dev not having certain files in correct folder. I am relaying this to you because even though this is an explanation, and as others state in it a solution, its still above my paygrade!

I will refer this to others as well I am familiar with on XDA, probably try working it out myself if no responses.... If this is a fix, would you please let me know? Post something to this effect in a little more detailed layout?!!

Thanks,

zach

[Miscellaneous Android Development] SteveOx1:
I'm loosing root permissions about once a day. A soft reboot and it's good again....For some reason when I install an app I'm not being prompted to Grant SU privileges.

Also the Root explorer button is greyed out on Es File explorer saying this option isn't available on my phone?

Anyone find a work a round?

Thinking of doing a clean install or possibly another SU app?
[Miscellaneous Android Development] coolbeans2016:
no dev herre, but not the only 1 to "just say no" on other su apps

Everything is actually working fine with this perm root/twrp for this device (sm-j320p). I have not done it yet, was hoping someone in here would post a more thorough walk-through on fixing root with es file explorer. The problem is with the dev's and where they placed the su privilege files for requesting root. Chainfires SuperSU went to system-less which my understanding is not hard coded, it just activates, grants with a script as necessary then is gone again. Xposed will be going system-less as well in the future. With your description, first question is what model of thi sm-j320p are you running? The device I have is not experiencing any lag really with su anymore, and es file explorer has always given option for trying to turn root on, just would not.....

Hope someone else from in here will see this and help you out, this has been one of the best threads for root/twrp I have ever had to use with all of the help put into it!'

zach

ps if ur device is right for this thread, try updating the binary for Chainfires SuperSU, think it should be ver. 2.76.....

remember, even when using root explorer for copying, pasting stuff before pasting into a folder to get some things accomplished you have to make sure r/w (su) is chosen as well................. js
[Miscellaneous Android Development] SteveOx1:
Im using the Sprint J320p. Maybe ill just reflash the Super su zip again in Twrp. I have root but the problem is the super su not prompting apps to grant permission. I tried to uninstall and reinstall apps to see if the permission box would pop up. Nothing..... If i can't grant permission i cant use any file Explorer.
[Miscellaneous Android Development] coolbeans2016:
FIX FOR ES FILE EXPLORER NOT ASKING FOR ROOT ACCESS:

7 files to copy from /su/bin to /system/xbin:

make sure r/w is on in Root Explorer before pasting

1. app_process

2. daemonsu

3. su

4. sukernel

5. supolicy

6. supolicy_wrapped

7. sush

Restart ES File Explorer

Turn on root explorer option

Just wanted to mention... when devices are not quite functioning right, either new out of the box, or new out of a store, when the kdz is available, like with Samsung, using odin, reloading the current firmware (5.1.1 AOL not the APE), fixed alot of issues with mine.

As soon as I get a build completed, I'll post it. I changed to cm13 and am still working threw build errors, I keep getting no rule to make target for files like audio_hw.o, and other .o files which are object files generated from .c files. Im talking to the guy that has the repo on github for our device so hopefully I'll make some more progress. It's compiled quit a bit of files in the out directory, so hopefully I'm getting closer.

All in all the J3 is alright.. It definitely needs some tweaks to the OS... I'm going to see if I can find Fast charge, Audio Mod apk. I'm really not up for having to do 10 different steps just to get better Audio. Any suggestions pls let me know.

I'm very happy with the Recovery as that was the first step with anything.

Androidlover5842? Yeah, I have the link to the github repository, the device tree for this J3. I wish I could do what your trying to do and help. Got a new laptop, so still setting up Android SDK after Java and working on my adb/fastboot commands. Can I ask you a question? If I want to pull a system.img file, and boot.img file off an android device (it has proper drivers loaded and is seen by both adb/fastboot), what are the commands to do this? ADB pull.....?? What?

thanks

[Miscellaneous Android Development] hooks405:
I haven't been able to do it, I read online somewhere that you could get them from an update.zip or I think even a twrp backup. I've also found numerous post about pulling it using DD, but I believe it's located somewhere in /dev/block/mmc...... best advice I have is Google it. Lol sorry

Adb pull will pull files from the phone though. Locating system.img, boot.img, and recovery.img I can't tell you how to do.
[Miscellaneous Android Development] Curtis1973:
No progress on themeing. I can do it. Don't care to really. Touchwiz is a complete garbage OS. Fully debloated and stripped to bare minimum with no apps installed it still drains the battery in under a day. I have zero interest in the device.
