[Galaxy Grand Prime General] mattman1978:
Samsung Galaxy Sm-S920L verizon straight talk. I loaded the micro gaps and added what I wanted. It's running great! NO problems! Appears to be rooted, but since there is no bloatware and EVERYTHING is enabled, I haven't had a reason to explore it. I was having issues with my EFS prior to installation. I couldn't get WIFI to work NO MATTER WHAT! I reflashed the factory files, even deleted the EFS and restored a TWRP backup. It HAD to be the EFS because nothing done to the other partitions would fix it. In any case, installing the ROM as listed in the instructions in the following link completely fixed my EFS along with a major upgrade. I LOVE my phone again! (Enabled hotspot, tethering and much more!)

Where and How?

For those advanced users that know exactly what to do here's your link:

https://jenkins.msm8916.com/job/Lin...axy_GRAND_Prime/job/los-13.0-gprimeltetfnvzw/

For those of us who need a bit more direction, here's how I did it:

**You MUST have a good quality USB cable. The cheapy charge cables sold at dollar stores or whatever isn't good enough! Use origional Samsung cable or a high-quality cable. DO not go past this step until you have the right cable. I don't care if you can transfer files to the phone or not, you MUST use the right cable. Take it from someone who nearly bricked his phone multiple times due to a crappy cable that he THOUGHT was working... :)

First, you will need ODIN to load the custom recovery. You will need the custom recovery to be successful.

https://samsungodin.com/

Get ODIN and the Samsung drivers. Unplug the phone from the USB on the computer and install the samsung drivers on your computer.

Unzip Odin (Or install, depending on what option you have).

Place the ODin folder somewhere you can find it. I used C:\program files\ODin

Download the files listed in the Jenkins link above. At the time of writing this, there was:

changelog-lineage-13.0_j6_20170608_NIGHTLY-gprimeltetfnvzw.txt	13.96 KB

lineage-13.0_j6_20170608_NIGHTLY-gprimeltetfnvzw.zip	326.46 MB

lineage-13.0_j6_20170608_NIGHTLY-gprimeltetfnvzw.zip.md5	86 B

LineageOSRecovery-lineage-13.0_j6_20170608_gprimeltetfnvzw.tar	9.08 MB

Yes you can skip the changelog, but it's negligable size makes it easy to DL.

What are the files? Changelog is just text to describe what he has updated/changed in this latest release.

The .zip file is the actual Operating System for your phone.

The .md5 file will allow TWRP to ensure the file is complete and correct prior to loading it on your phone. VERY important.

The OSRecovery-something.tar is the recovery partition that must be loaded FIRST on your phone!

Place the recovery file on your computer, where you can find it.

The recovery has TWRP, version 3.1.1 at the time of my writing this. Very nice updates to it.

IF you want the GOOGLE APPS as well, you MUST download the GAPPS from here:

http://opengapps.org/

Use the ARM, Select Android 6.0 and then read about the variants. I went with the Micro, which gives you the Play store. Then, I added the Google services I actually use, leaving off the extras.

Now, go find the ODIN.exe file. DO NOT DOUBLE-CLICK!

Disable your anti-virus first, then Right-click on it and select RUN AS ADMINISTRATOR.

Shut the phone down.

Boot the phone into DOWNLOAD mode. Hold the side power button, the volume DOWN button, AND the front, bottom, middle button down all at the same time for a few seconds and then release them. It should go into Download mode. Hit the key to continue into download mode.

Use ODIN to load the Recovery to your phone. Don't format anything, don't muss around. Just load the stinking Recovery and then GET OUT OF ODIN! If misused, it can totally brick your phone. Note: Odin will check the file prior to loading it, it will "think" for a few moments before allowing you to load it to the phone.

TO use ODIN: click on the AP button, find your "SomethingOSRECOVERY-something.tar" and select it. Don't muss with options or anything else, just hit START and wait.

Assuming you were successful, you can unplug the phone and restart it normally if it doesn't restart automatically. It should come up and look EXACTLY like your old system. If so, GREAT!

Now, boot the phone to RECOVERY and let's have a look at that new TWRP recovery.

To do this, Hold the side power button, the volume UP button, AND the front, bottom, middle button down all at the same time for a few seconds and then release them. It should say "Recovery" at the top of the screen.

Now, my experience with this newer TWRP is that you have to hit the side button to turn off the screen and then hit it again before it will allow you to unlock it. Weird, but hey.

Before you do anything more, BACK UP EVERYTHING! Once they are backed up, restart the phone to "SYSTEM" and save them to your computer. Make sure you back up the EFS and SYSTEM Partitions.

Place the following files on your phone in the INTERNAL STORAGE. Do not use the Micro SDCard for this part. It really does make a difference. I was NOT successful using the Micro SDCard to load the files from. I had to move them to the INTERNAL STORAGE for TWRP to successfully load them.

lineage-13.0_j6_20170608_NIGHTLY-gprimeltetfnvzw.zip	326.46 MB

lineage-13.0_j6_20170608_NIGHTLY-gprimeltetfnvzw.zip.md5	86 B

Now, you have a perfect backup of your phone and a TWRP recovery. In theory, you should be able to back up to your old system if anything goes wrong.

Now, Boot the phone back to RECOVERY.

A good time to say another prayer.

Go back into TWRP as before, go to WIPE

Now, don't wipe anything extra. I wiped the following:

Dalvik

Data

Cache

System

I leave Internal Storage and Micro SDCard along with USB UNCHECKED and NOT WIPED.

Go back to the main screen, select Install. You may have to change the Storage location by clicking on Select Storage button and selecting Internal Storage. Find the .md5 and .zip files listed above. Select them and go!

If things go well, it will report success. Otherwise, try again. You may have to re-download and retry the whole thing. If not successful, restore the backup and go from there. Restoring backups are much more successful if you do it from the internal storage and not the SD card.

If memory serves, you have the option to "WIPE" as soon as it reports success. Wipe the Dav and Cach.

If you like, restart your phone now to view your new OS (without GAPPS).

Otherwise, if you'd like, go ahead and install the GAPPS. Place them in the same location as the other installed files and hit the Install button again in TWRP. Find your GAPPS zip file and install it.

Restart now and you will have the Google apps package you selected.

From there, it's standard issue customization of the phone.

If you have trouble getting it on the wireless internet, shut down and swap sim cards with someone else and restart your phone. Make one call and then shut down and swap back. Restart.

It worked for me anytime I had issues with the network after installing a ROM. I didn't have that issue on THIS ROM above, but if you do, that may fix it. I used my wife's SIM from her phone that's exactly like my own. I wasn't a huge fan of the background or the "Theme" but that's easy enough to change. This change takes you all the way to Android 6.0.1. Not bad!

If you go back up toward the Root of Jenkins download site, you will find files for Lineage14. I was not as successful with 14. Maybe he will get it working better soon.

Note: Prior to this upgrade, I had a buggy EFS. It would not allow any wifi. Soon, things got worse and I was stuck in a boot-loop. I believe the rooting program I had previously used messed up the permissions on my EFS. I had a backup of the EFS, so I had to use ODIN to Format the EFS and then reload it using TWRP. After that, phone would boot and it would work on the wireless network, just not WIFI. Never got WIFI working until I loaded this custom ROM. Now, everything works! VERY awesome! This upgrade completely fixed that problem! I hope others have as good of luck with it as I did. It took me the better part of a week to get it right. Using a Cheap USB cable and attempting to use the external SD card to load Roms and backups both caused a lot of problems. Move all files to the internal storage prior to loading them using TWRP. I honestly believe I included every necessary step. If I left something out or if it doesn't work for you, I'm sorry, but I'm not liable.

If you just want to root this phone, go through the steps above to get TWRP custom recovery on your phone. Back up everything! Download SuperSU zip file (Recovery Flashable) from this site: http://www.supersu.com/download

Put the SuperSU.zip on your internal storage (I left it in the download folder).

Restart the phone to the recovery, select install and select the SuperSU.zip. It will install the SuperSU to the SYSTEM partition automatically rooting your phone! In my opinion, this is by far the best and safest way to root a phone. Should work practically every time! Personally, the ability to backup using TWRP is something every phone should have to start with. Rooting it is simple after that.
