BOOTLOOP Samsung J7 Refine

Hi Guys I need your help with my phone.

Suddenly after the process my phone is acting strange I search on google and people call it boot loop.

What I did is follow all the steps that was provided in here. I have successfully rooter my device, but when I setup the passcode for my phone thats the time it started acting strange.

It keeps on rebooting.

Anyone here please help :(

I am just new to this :(

Hi sir, I've seen a lot of your post regarding rooting SM-J737P.

I have successfully rooted my device but it is now on boot loop after I have tried to setup a passcode on the device.

Please help me on what to do with this.

I have downloaded a firmware from youtube but it does not flash successfully since my device says that the current firmware is in binary 6 and the firmware version that I am trying to flash is in binary 4.

I am currently on android 9.0 before the boot loop but now I dont have any operating system or firmware installed on my phone. ( after i wipe the data using TWRP )

I am currently downloading the Android 8.0 that you have posted on one of the threads.

It is on different binary version though, but Ill try to follow the steps that I have seen on one of your posts so I can downgrade from android 9.0 to android 8.0.

If you have better suggestion please let me know.

Thank you in advance!

I have successfully rooted my samsung j7 refine ( android 9.0 ) using this method. ( thanks to this tutorial ):good:

It was a little bit hard since I dont have enough knowledge for this.

But it was done successfully, I just have problems with my lock screen.

When I try to create my password for my phone it says incorrect ( thought i am typing it right, i only have 4 digit password ).

And I looked up in the settings, I found out that though I have successfully setup a passcode for this phone it still shows on the settings that I have selected lock settings as Swipe.

Anyone who has idea regarding this that can help me please.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] jokono421:
I wouldn't set up a password to unlock phone during intial set up. Also certain apps you try deleting will put your phone in bootloop. Like payment service, some knox, and galaxy store. Also i have an app disabler. I disable security log agent.Plus make sure you have busy box installed.

l replicated your issue. In fact if you setup a lockscreen you will go in bootloop. So do not root if you want a lock on your phone with anything other then swipe to unlock.

I am not a dev.I'm pretty sure there is a way to fix it and repack your rom with the fix. If anyone does find a fix please pm me.

☆KØŁØЯΛĐØ☆'s instructions worked for me to root a SM-J737U (though I needed to use Magisk Manager to patch my own boot image instead of using the provided patched J737P boot image).
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] Roper08:
I've seen some people have gotten this to work on pie 9.0.

I'm on pie, I've found everything needed except for the combination file. I've checked through the links provided in previous post. Just wondering if anyone could point me in the right direction to get those?

Or would it be better to revert back to Oreo?
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] zrhoffman:
9.0 is what I rooted my J737U on (specifically, J737UUES3BSI1 from 2019-09-23). I had no need for any combination file, I just

1. Extracted boot.img from the J737UUES3BSI1 firmware and uploaded the boot.img to my unrooted device

2. Installed Magisk Manager and patched boot.img

3. Copied magisk_patched.img back to my computer, renamed it to boot.img, and tarred it

4. Followed ☆KØŁØЯΛĐØ☆'s instructions to use Odin to install the firmware

5. Followed ☆KØŁØЯΛĐØ☆'s instructions to use the patched Odin to install my boot.img.tar in the AP slot

From there, it makes you format your userdata, but the device is rooted at that point.

Noob question here...

I'm running on J737PVPU7BTE1 pie 9.0.

I've downloaded to stock firmware, extracted it to my desktop. Then extracted the boot. Img from the Ap file.

Is the Ap file where I'm supposed to get the boot. Img from?

Also I've read through the threads, and forums, and Google, about how to extract it out of lz4 format.. I seen where they talked about. . Lz4 tools in previous post, but I really haven't found out where to get that, or how to use it..

Is there not another program other than 7zip that will do that?

Any help is greatly appreciated.. Thanks guys
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] zrhoffman:
IMO the only tool you should be using to unlz4 files is lz4. You can download a Windows build from the Releases section of github.com/lz4/lz4 (my post count is under 10 so I can't make that a link)

Unlz4ing a file is just

lz4 -d boot.img.lz4
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] jokono421:
Let me help further. To find combinations files go to samsung website you need to create an account an log in. There you can download combination files. Zrhoffman is correct with his method. The 1st time yu root 9.0 pie no combination files are needed. Unless you are in the top 1% people who root an never have issues you will need to follow my steps. Unfortunately once you get caught in bootloop the only easy way to re root stock firmware is if you flash combination in between. Please zrhoffman is correct but if u get caught in bootloop follow my instructions. Or else you will be stuck there feeling stupid why you can not root after you just did following say way. An do not ever uncheck unlock bootloader once u hit pie root

Non of these methods work for 9.0 u7 at all. I cant get this phone root what so ever
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] jokono421:
Might work

I recently ran in problems where phone would get stuck on samsung screen. What i do is hold power up,home, and power for 5secs. No longer or you will go to twrp. Then my phone starts instead of staying stuck. Also use twrp i provided ,flash your magiskpatched boot image too boot.

Hello, I just spent the last 1-2 hours reading through this thread going down memory lane honestly. But I ended up here again because I can't sign into Samsung Account on my J7. I seen it mentioned that it was an issue, but I didn't see anyone responding back to those problems.

Has anyone been able to sign into their samsung account after rooting?
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] jokono421:
With stock before root download an app called migrate. After you sign in samsung app. Save apk+date. Root phone then follow migrate process to restore.. Might work

so i flashed factory combination software with binary 6, thinking that because it was a lower android version i would be able to use that to downgrade to oreo. problem is now im stuck on that firmware. tried to flash oreo and pie, neither worked. when i try to flash pie it give the error that device:6 binary:4.

HELP PLS!!!!!, this software is basically useless

Sorry for the really late response, but hopefully, I find my J7 Refine soon and have better luck fixing it on my laptop than I did on the desktop that I was using at the time, because it is possible that the USB ports on the desktop could have been the culprit.

%Hey I think I'll ask for help now. I've been trying for a few days to do this. I have installed twrp, but I can't see the computer to transfer files. I have formated data and rebooted back into twrp. Still nothing. I have latest adb and samsung drivers. I've used multiple USB and ports. So I went back to stock. I am also able to patch boot.img with magisk. Then I go to odin and flash stock ap, bl, and cp. Reboot back into patched Odin and flash magisk patched tar. It boots up and I have root but no twrp. So I use flashify with root permission. Then boot to twrp. But! Then the screen is black and it says little red letters I can't use custom binaries or something like that because I wasn't able to flash the 3 files from twrp to fix it. Hope someone sees this. Thanks

Nevermind. I just read I will need a SD card. I'll try it after I buy one
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] pauljulian:
Absolutely... only question I have now is where the damned SIM card landed when it bounced off the desk and into the carpeting... Don't think you can help me with that, new friend.

Yeah... was kind of a long distance, remote control party, to be honest about it.... And yeah, your instructions are dead on and straightforward...

Owing to a difference in current image on the phone, yeah, that was a big thing, but really no one's fault. was great to have it rooted, and even if I don't find the SIM, I can use it as a PDA and ebook reader, and really everything else, except calling and text... If I don't find it, I should be getting paid Monday, and I think Boost only charges 10 bucks for flashing a new SIM... but at least I can have everything working and usable... I can now use App2SD, from the sharp lady that built it... really, that's been my only thing, apart from Titanium, and a few other apps and plugins that need root.

Once you figure out how to bypass Magisk, that'd be cool, but this is good to go, as is.

Thanks again, my friend.

Shalom Aleichem to you and yours.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] ☆KØŁØЯΛĐØ☆:
Managed to slightly tweak both the build.prop & default.prop earlier before bootlooping. Baby steps lol Maybe modifying the system.img will have better results. Just some food for thought
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] Vyp3r M0dz:
I have done it as stated by you and otherwise within safety of my device.

I can not into twrp 15 times and I get the same thing. It also doesn't matter if I flash the files singly or at some time, I get the same result either way.

It has to be something different on my variant of the j7. Which I'm hoping we can figure out and resolve.

---------- Post added at 09:24 AM ---------- Previous post was at 08:53 AM ----------

I will make a zip containing the stock firmware and patched boot.img for you.

The rooting of the j737p wasn't too difficult, but like he has stated his instructions are device specific. So it was stressful being as I was feeling my way through it hoping it was a similar process.

I added a screenshot of my root check to verify.

https://www.mediafire.com/view/odaxzw23pwdczwz

What I'm stuck on is finding a recovery or room for my device.

I can get twrp to flash to the j737p and functions. However, I haven't figured out how to get it to boot into the OS yet.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] ☆KØŁØЯΛĐØ☆:
I'm having a little trouble understanding your complication with TWRP. You cannot get your phone to reboot normally after flashing the 3 .zip files in TWRP?
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] Vyp3r M0dz:
Yes, after twrp is on it seems to do fine through the recovery menu. But soon as I reboot after flashing the zip files regardless how I do them, it boot loops.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] ☆KØŁØЯΛĐØ☆:
When booting into TWRP for the first time, did you go to WIPE > FORMAT, input yes, & format your data? If you formated the data & did an immediate reboot back into twrp, then you shouldnt have a problem rebooting normally. Also, don't clear the cache any time you flash in TWRP. Oreo is a very sensitive OS. If that doesn't work then we'll go from there.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] Vyp3r M0dz:
Yeah I did that as well. I am on the j737PVPS2ASA1 if that changes anything on your tutorial for twrp.

I used your root method with my own boot.img and firmware and worked well. But can't get twrp to let me past recovery yet.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] ☆KØŁØЯΛĐØ☆:
After you boot into TWRP the second time, turn the phone completely off instead of flashing the .zip files. Reboot the phone like normal & see if that works. If it does, then you can flash the files in TWRP. If it doesnt you'll have to wait until I get off work so u can troubleshoot further. Can only do so much away from my laptop
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] ☆KØŁØЯΛĐØ☆:
I'm off work now & able to assist. Could you enlighten me on what Carrier you have? General search tells me its Sprint but want to make sure. Also, I need a copy of your stock boot.img & recovery.img.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] Vyp3r M0dz:
Sorry for the delayed response. I have been busy and came up on a hang up with setting sd as internal. I also broke the screen on my 2nd j737p I use for testing prior to executing on my main one. I am still in search of a custom recovery as well as a custom rom.

I am on boost mobile ( sprint mvno )

I am going to zip up my files and upload them to mediafire now. I have needed to do such for another CDA user who has not obtained a succesful root on his of the same variant anyways. As long as my low tier rank allows me to do so I will post the DL link as a response on here this evening.

P.S.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] ☆KØŁØЯΛĐØ☆:
I would bet my next paycheck that if a custom ROM existed for this device, someone would've posted a root guide before me lol As far as custom recovery, there isn't any. Not an Official one, that is. As stated, this is an unofficial TWRP Recovery. It will work with the Boost J737P variant bc it was compiled using its stock, fresh-out-the-factory ramdisk.

So long as you have your stock firmware, you won't need to worry. Most the firmware out there on odd sites is not actual stock or its packaged wrong. I grab mine off https://fullstockfirmwaredownload.com. They link you directly to a repository of every stock Samsung firmware, after paying $3 [super cheap]. An easy way to know if you have actual stock is by extracting the .tar files & observing if the files inside have LZ4 compression. If they are, you 1) have actual stock & 2) need to extract/convert all files out of LZ4, then rezip them into ..tar format.

UPDATE

​

After a good 2 weeks [roughly] of extensive testing, I can conclude the following:

The latest software version (J737PVPS3ASC2), along with the April 1, 2019 Security Patch Update, are compatible with the same root method provided in my OP. Feel free to install the OS updates before rooting.....or don't ?

There is a

massive amount

of Security measurements/protocols/functions/apps (whatever you wish to call it) that can be removed &/or uninstalled successfully via various forms (I prefer using ADB

The build.prop can be edited successfully, provided you use an outside application. Root apps such as Root Essentials or ES File Explorer Manager will allow editing but upon reboot will return to normal (ie. remain unedited)

Due to our device being a User build & not a Developer build, the SELinux remains enforced. However, I have managed to set the User function from DPI to

ROOT

(ie. Root functionality is set as owner, which is half the way to setting SELinux as Permissive)

TWRP functionality is around 70/30. By that I mean that all normal TWRP functions are good to go (ie. Wipe, Install, Backup + Restore, etc..) whereas sideload & MTP appear to be dormant. Using an Ext. SD Card is

strongly

recommended

Any & all Magisk MODs that pertain to Samsung/Exynos/Oreo 8.0.x/Universal will flash successfully. Read the instructions, if provided by the MOD Dev, carefully. Some MODs require tweaking, file placement, etc.. If you fail to do so & end up bricking your device, it is

your dumbass fault

SuperSU is excellent & no I don't give a fųck what you think about my opinion. That being said, I'm not the only one who wishes SuperSU didn't sell out & become unsupported....which brings me to my next bullet point

Contrary to popular belief, SuperSU can be flashed in TWRP successfully. However, since flashing Magisk to the same location that SuperSU normally installs into, SuperSU doesn't stick after reboot (YET)

I am working on a method to replace MagiskSU with SuperSU, including a workaround to updating the binary. It won't be an overnight task but I'm goin to stay on top of it. Feel free to shoot me an email if you want to help assist me in finding a way or if you have questions pertaining to my ROOT + TWRP guide koloradokiller848@gmail.com

I am on the hunt for a rom still ... I am scanning the web through all official and unofficial roms. I am curious though the j7 prime and the j7 refine both have the same specs hardware wise other than little things such as camera and internal storage and such. the core hardware is all the same it has a different bootloader and device id basically is it ... what keeps me from taking a rom/recovery from the prime and using my stock firmware and bootloader to make one of them work on my j737 ??? both exynos both arm8l both sdk26.

Also I got my firmware from https://www.sammobile.com/firmwares/ and paid for them. I however cannot locate my stock boot img anymore.

I have taken all the files and programs I personally used to root my j737p and orginized them in a clean file structure as well I modified your walkthrough with changes to fit what I did to achieve root and have it all zipped up loading to mediafire now ... Ill have the link shared for that soon.

I have to check my XDA privileges to verify I can do so at my current tier, but I may make a new post specifically for my j7 variant so others can find it for their use easier. have you and topjohn cited in the txt file and would link you both to the post if I can post my own thread at my tier.

****** On a side note, I am also in process of trying to root my Lenovo tablet a10-70f I had a supersu oneclick type root on it from when supersu was good. I have removed it and upgraded to marshmallow. I had twrp on it however having issues getting it again, I do have a compiled list of resources to try gettin it on there via spflash or mdktools with a selection of twrp boot images and other such files to play with and see what works when I get time. I as well, have an LG V20 H910 I may replace the screen on soon, in which if I do I plan to root and rom. If you have any info on those devices or would like to be updated once im successful let me know.

Curiosity will open doors you never dreamt of. It's that exact feeling that sparked my interest in the whole "rooting" concept. Unfortunately, I'm a reverse-engineer & to accurately answer your question you would need to ask a Developer. I do know that compiling a custom ROM takes more than one person, each one handling a certain aspect(s). To compile a custom recovery like TWRP, you will need your stock Recovery.img & the ramdisk that is packed inside it.

Sometimes, custom ROMs suck major ass. It's often better to tweak your own sh¡t instead of flashing somethin that someone else created. That way you ensure you get what you want & you arent just settling with another person's idea.​

Thank you for the citations buddy. Link posting privileges are granted after you post 10 times, be it by commenting on a post or starting a new one.

I delve in all things Android but Samsung is my bread & butter. I'm well adversed in ADB & Fastboot, which comes in real handy when working with those devices. I dont have those devices on hand to do any work with but I would happily assist in any way I can.

You can email me at koloradokiller848@gmail.com if you have questions or are curious about anything regarding Android. Idk everything Android but I'm certainly not a noob lol

I'm running the April 1st, 2019 security update also on the newest firmware. If you need the stock, lemme know. As far as booting up fully after flashing the 3 files in TWRP, I can troubleshoot a few options.

If you cleared the dalvik + cache after flashing, stop that sh¡t. Wiping the caches are nonsensical, but I'm assuming you didnt do that.

If you are still stuck on the carrier logo, force restart the phone by holding Vol - & Power for 7 seconds, then reboot immediately into TWRP. Once in TWRP, flash the patched_boot.img. It won't force you to reset your device again & it should get you back into your phone.

If the above 2 options didnt work, let me know & we'll go from there my man
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] ProphecyOD:
Ok I think I might have cleared it the first time by have since quit. When I load the patch_boot.img on the sd card it does not show up in twrp? Does it need to be a zip?

Probably be a good idea to have the stock file.
