TWRP fails for me.

Samsung Galaxy On5 SimpleMobile version. (which runs off Tmo towers)

model SM-S550TL

I Wish this would work for my unit. I attempted in odin and have flashed TWRP on other devices, Sadly through Odin I am getting a secure check fail via the handheld.

"SECURE CHECK FAIL: RECOVERY"

and basically have to do a battery pull and reboot.

Any help is appreciated guys!

This seems to be the latest varient of the On5 stock android 6.0.1

Thank you for the detailed explanation on rooting this device. FIrst time droid user and first time I rooted. It appeared a success.

Does anyone have issues with link2sd on their on5? I have rooted and have link2sd installed.

It will link apps but when you try to run them, they fail. I end up having to move them to SD card to get them to run.

Seems pointless because it's basically the app2sd program that moves them.

Anything that is linked refuses to run until it's moved. Trying to understand what it going on, the link2sd faq's suggest it could be a "stateless" file system. Seems odd to me though that it wasn't mentioned here if that is the case. So I'm wondering did I do something wrong?
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] czarsuperstar@gmail.com:
Maybe this will help. It's beta but I used [MENTION=5672995]jcadduono[/MENTION]'s device tree and added Sdext to the recovery and partition sd card. It doesn't link at start up so you have to select quick boot option and than it will link. I am working on a stable version but right now it's beta. http://xdaforums.com/showpost.php?p=69635006&postcount=22
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] jce2005:
Link2SD does not seem to work very well on the On5...... Also, no updated PRO version and developer is not really responsive.

Best to use is " Apps2SD Pro " ( note the "s" after App ).... There is also App2SD which is different. Very good program, lots of features and the BEST developer I have worked with on getting everything running.
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] czarsuperstar@gmail.com:
Did you try the image I compiled? It is working for me.
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] jce2005:
I downloaded your image and keep it safe.... ( Great work BTW, Thx )...... Currently, everything is running perfect and since I need my phone daily, I haven't messed around with it anymore..... But certainly will try your image once I have troubles or run into troubles.....

The only advantage I see with Apps2SD is, that at any time, I can make a "ext4" backup of the sdcard ( three partitions ( FAT32/ext4/Linux swap ), change to any new, bigger card and just do a restore and all is working again...... Not sure if it would be as easy to do with "adoptable storage"...... Like doing a TWRP backup/restore......

Any thoughts ?

[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] czarsuperstar@gmail.com:
Flashify doesn't work for the On5 how did you get it to flash? You have to use the tar and flash through Odin. Than you can flash recovery through TWRP. Select install image , pick the image and check recovery and flash. Than reboot recovery to make sure all is well and reboot into the system (Android).

This might help:

http://www.tecpharmacy.com/2016/10/download-samsung-galaxy-on5-sm-g550t1.html

This website seems to have the links for the firmware files of your phone. Try to flash these with odin and see what happens, since you have nothing to lose at this point.
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] rein013:
actually the phone still works fine . when trying to flash TWRP it just errors and the phone reboots normally however since the phone is a prepaid and i got a month to return the **** back to the retail store i could care less if i break it so if anyone has any ideas for me to try let me know . if it breaks it breaks ; so like you say , nothing to lose :D

the phone we have is a tracfone version of tmobile called simplemobile SM-S550TL so i wonder if we could flash the total tmobile fileset to this phone but then again i know tracfone are known to locking their **** down so maybe that's why we cant even oden the tmobile TWRP files ? but i have no clue how all this **** works .

thanks for the link btw :highfive:

edit: and to think the only reason i'm doing this is to regain the feature that samsung removed , adoptable storage , as i ran out of storage space and was like wth ? android should mix the memory card as storage BUT NO ! feature removed . no more samsungs for me .
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] ashyx:
Ensure that OEM unlocking is enabled in developer settings.

If you still get the error then it's likely the device provider has locked the bootloader.
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] czarsuperstar@gmail.com:
I don't think it would be wise to flash this recovery made for T-Mobile and Metro. The kernel is different. It may cause complications.

---------- Post added at 12:38 PM ---------- Previous post was at 12:35 PM ----------

If you want to build a recovery for the phone I would get the device tree for the on5 split your boot.img using Mkboot tools replace the DT image and kernel (which has to be renamed to zImage and it should build successfully.

actually it worked two different times kinda that iv tried.... first time it softbricked my phone...displaying fatal exception...or panic mode if u rather... but the Master FRP reset file and the tmb combination files that I previously described you got me back out .........the second time like a dummy i flashed the wrong recovery an thats how i ended up with the purple writing of signature falire an bit set.....And the four single files that he made the video with got me back stock.......with that bein said ....flashify nvr warned/ notified /or stated that on5 was not compatable...as if a normal incompatable flasher of any of the sort would.....now some four ground on all that ....before any of the topic of my troubles that i posted .......nandroid /twrp manager / both did not work an gave me close to the same issues ...jus was able to reflash thru odin an was back at ground zero...an..i have yet to fimd any flasher app to sucessfully work for any custom recovery/ custom roms /kernels / or even get a boot anamations ...to work for that matter....pretty much jus basic root an superuser ....nothin special

I installed Twrp via Odin and then flashed supersu 2.79 using Twrp with no problems and now have root. Installed Twrp app from play store for easy access to custom recovery.

[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] czarsuperstar@gmail.com:
This is the method that I used. Go to about device and tap build number like 5 times until it states you have enabled Development mode. Check OEM unlock and USB debugging. Also check unknown sources in security and uncheck Android device manager and than go to download mode and prepare Odin for flashing recovery tar. Under options in Odin uncheck auto reboot then flash the tar. After completion pull out the battery and put it back in and hold volume up ,home and power until you get into recovery and then flash SuperSU.zip

Can someone give me some guidance on how to port this twrp to the galaxy on5, model sm-s550tl? It would really be appreciated! If this is not possible, I understand.
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] ashyx:
There's a guy attempting to port twrp to this device, but he's having issues.

I've had a bit of communication with him. The signs are that the carrier has locked the bootloader as it doesn't seem to accept unsigned files.

What happens when you flash the g550t twrp recovery, do you get the secure check fail error?
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] hydroman202:
Yep. That's the error I get. If I had to guess, maybe the boot im g for this variant I have, (sm-s55t0l), is too different from the others to get it to flash without issues? I know that when I owned the galaxy core prime, it said the same error until the original boot image was modded and flashed. If there was a way to extract the boot img without root, there might be a way to get a working recovery.
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] ashyx:
Could be, need the s550tl boot image to compare the headers.

If it has a special header then this could be the issue. That is if indeed the bootloader is indeed not locked.

Does this carrier make a habit of locking bootloaders?

I know where the firmware is but it's not free.

Have you tried to download the stock firmware via smartswitch?
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] hydroman202:
Not yet, i have to wait until I find Wi-Fi to attempt to download it. If it even exist.

Should be on the device/box or can use Samsung phone info.

[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] AndroidKing:

The twrp recovery doesnt work on this model sadly any help to get it working cause in download mode it says some error (recovery)

Model SM- G550TL

[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] hydroman202:
​

The recovery boots fine. No issues.
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] ashyx:
OK so my next step is to simply unpack and repack the stock recovery. If you can't flash that then we know it's either missing header info or needs to be signed. If it's the latter we're in trouble.

I will be investigating the headers later and comparing with the G550T.

Do you know if Simple mobile make a habit of locking bootloaders?

Is there a better thread we can post this stuff in instead of hijacking this one?
[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] hydroman202:
I will make a new thread. As for flashing the recovery after unpacking and repacking it, I will do that and let you know in the new thread the results.

You are actually just suppose to hold Vol+Home+power until you see the boot screen turn on then let go right when you see it other wise it boots into system

---------- Post added at 03:14 PM ---------- Previous post was at 03:05 PM ----------

The first time I did this on my SM-G550T1 Metro PCS phone it worked perfectly no problems. I unrooted to see if any updates were available like a fool. I wasn't thinking straight. When I went to reroot it though I followed the exact same instructions as before with the same files I used the previous time but when I flashed the Update.zip thru twrp for the second time my phone would not boot up again. The screen would illuminate and that's it. No logo nothing. It still booted into download mode and recovery though. I just took the phone to the store I bought it from and told them I did a factory reset and I didn't come back on. They inspected the phone for water damage and didn't find any so they replaced it for me. I'm looking to install tarp and root it again but I'm a little paranoid about it after all that.

[Samsung Galaxy On5 ROMs, Kernels, Recoveries, & Ot] hydroman202:
Hello, I was wondering, under developer settings on this phone, (galaxy on5) I found an OEM Unlock option. I understand this allows the bootloader to be unlocked. What I don't understand is how. Every guide I seem to run across says fastboot is required, but I cannot figure out how to get into that mode. All ADB does when I type "adb reboot fastboot", or even " adb reboot bootloader" is that it just reboots into the os. Is there something I'm missing? If it helps at all, the "OEM unlock function" is enabled by default.
