This started as a beg for help thread, but since the GS4 is coming up on 3 generations old, help is quite slow, yet does still exist as of this edit (3-20-15).
None the less, I will try to explain what happened so that people searching for similar problems might find this thread and resolve their issues.
I soft bricked the phone flashing PacMan. ... The instructions CLEARLY stated that you need to flash the rom, then flash GApps. Well, I forgot to Flash Gapps because I was so excited that I had a successful root and new rom to test that I finger ganged the phone.... The phone booted just fine and worked just fine, but I did not have ANY google apps, and went into a panic... LESSON #1 DO NOT PANIC......
What I failed to realize is that Android Lolipop (at least PacMan's version) requires the user to select options in the developer section of the settings menu to enable you to boot into your custom recovery after you have flashed your custom rom.... I DID NOT KNOW THIS and the information was NOT readily available. So what happened was I panicked and tried to flash another recovery which was apparently NOT the correct recovery for my phone.. (the cascade of errors began here). My phone was soft bricked and NOTHING I did would get me out of it.
So, after at least 50 attempts using Odin to try and flash a good recovery, re-root the phone, whatever I could think of, I finally got out of soft brick, and back to a working phone, yet still no google apps, and no recovery (or so I thought).
By this time, I had asked ....no. begged for help on 2 or 3 different threads to no avail when what I thought was a brain storm came to me.... I googled and located the google play store apk, and google play services apk and thought that if I could just get these 2 things installed, I would be able to log onto the google play store and download the apps I need and all would be right with the world....... Yeah.... Remember the cascade of errors thing I mentioned a few lines up ^^^ ?
Once I installed those 2 apk's and rebooted the phone, I was in nag screen hell with no way out, no custom recovery (remember...or so I thought) and no way to access ANYTHING on the phone because literally the second I hit "ok" on the nag screen, it would immediately pop back up...This "nag screen" was the one that pops up and tells you that "google play services has stopped working".. I came inches away from launching the phone against the wall and buying another one... something... anything but a Samsung GS4.
So here we are, 14 hours (of actual face in the phone, Odin, XDA, Google, YouTube) frantically searching for ANY solution.....and NOTHING presented itself, when I decided to take a step back and walk away from it for a couple of hours.......
The next thing I tried was pounding my way through the nag screen... Literally hitting the "ok" toggle to clear the screen, while instantly trying to hit any other button on the screen to get me into the settings menu, because during my little self imposed time out, I had an epiphany.... of sorts..... What really happened is that I remembered seeing a "factory reset" toggle in the settings menus somewhere.....and I was determined to find it........ SO....... 13,386,329 clicks of the "ok" button later, I managed to engage the factory reset switch at the exact right moment, followed by another 4,388 presses of the "ok" button to get to the "confirm" button.......... and like a beacon from heaven...... My phone rebooted, and factory reset, and the #%g^7**&^|@# nag screen was GONE !!!!! Oh my GOD it was GONE !!!!!!! After recovering from my full blown conniption, catching my breath and feeling like a raver must feel after a good night of Molly and glow stick euphoria, I had a working phone again..... almost.
What I did next was go immediately to Odin, re-root the phone, install a DIFFERENT rom, and the latest version of TWRP and like another beacon from the gods I had a wonderfully functional phone with all of the google apps I needed.... and all was good with the world........Pretty much....
I am nearly certain that I cost myself 5 years of healthy living with the stress I imposed upon myself throughout this ordeal ---- The following are lessons learned. Hopefully they save you from madness...
(1) Do NOT use a USB hub to connect your phone to the computer. The phone MUST be connected directly to a USB port on your machine.
(2) Understand the workings of the rom you are going to flash BEFORE you flash it.
(3) DO NOT PANIC
(4) DO NOT randomly install apk's just because you think you are smarter than a 5th grader, and you are so mad your phone doesn't work, you are going to try anything regardless of how retarded it might be.
LAST BUT NOT LEAST and actually probably the MOST IMPORTANT thing to do is locate, download and CONFIRM GOOD a stock firmware for YOUR phone BEFORE YOU ROOT or flash a new rom..... If you get to brick he11 like I did, you will spend more time searching for the tools to get back to zero than you can imagine. You will be revved up, angry with the world, and your google fu will fail you......miserably I might add......
Get all of your ducks in a row BEFORE you root, and before you flash a new rom. That means finding the stock firmware and opening it up in Odin with your phone connected to CONFIRM you have a good firmware to go back to should you fail miserably.... Your very sanity could depend on it...

Does anyone have and is willing to share a stock Galaxy S4 rom so I can go back to stock on my phone? I am currently soft bricked and completely dead in the water...
I need to be able to flash the rom using Odin since that is the ONLY way I can communicate with this phone right now....I can flash whatever recovery I want using Odin, but I cannot boot into that recovery once successfully flashed with Odin. It boot loops and goes back to the completely useless PacMan 5.02 rom I flashed previously that repeatedly shows the "google play services has stopped working" screen.... and no number of attempts to clear it by hitting ok will get me to a working desktop
I bricked my phone by flashing PacMan and forgetting to flash GAPPS before rebooting, then trying to install google play services apk and google play store apk manually because I could not get back into recovery for whatever reason....
I have spent the ENTIRE day searching for a stock rom that I can flash with Odin so I can at least get back to zero with this S4 which is actually a brand new phone for me....
PLEASE do not link me to mediafire or rapidgator downloads because I have tried every one of those that google will reveal.. I need one that YOU know is good, and will work. NONE.... NOT ONE of the files I have been able to find online are legitimate .tar files... They ALL unzip with errors and I have tried them on multiple computers.....Multiple download attempts and NOTHING... I have literally been at this for 10 hours now and really need some love.
On a side note, if I can pull the stock rom from my wifes brand new S4 without screwing up her phone, PLEASE tell me how to do that. She literally picked up her brand new replacement S4 today...
Any help is genuinely appreciated... PLEASE.

Man thank you! THANK YOU! I really appreciate it... I woke this morning to find this reply after leaving my computer running all night for another corrupted downloaded image file.... I have my fingers crossed !!! THANK YOU
P.S. how do I know which one of those files I actually need? I have no idea what the difference is in each of those folders.... Forgive me for noob but I really am pretty noob at this.....
I just looked at the link to help you and noticed that Wilco stops at the NAE baseband. A lot of phones are on the NG2 baseband and if you have a 720T, it could be even a different baseband. Go to settings, "About Phone". Look for" "Baseband" and "Model Number". Write that information down. Once you have that, the last three characters are what is in the list in the link KennyG123 sent you. (For example, I have the original S4 so I have a SPH-L720 and my baseband is L720VPUFNG2 (or NG2 for short. Which was not on that list.) If it is not on the list, go to www.sammobile.com and search for your model number (For example, I am on the SPH-L720. If you just bought your phone from Sprint, you probably have the SPH-L720 or SPH-L720T). You can download the tar file from there. It is a little slow but it will get it done for you. The tar file for both phones are here in this forum if you want to search but going to Sammobile would probably be a little easier from the sounds of it.

Hey brother, thank you so much for the help and reply. I might have forgot to mention that I cannot get into the phone to read the model # or get any information from it at all. The nag screen telling me that google play services has stopped working is so persistent that I can't do anything with the phone once it boots.
Is there a way to brute force wipe the phone so that the only thing left when that process is done is a custom recovery like TWRP or Philz or anything other than stock?
If so, would you be so kind as to point me in the direction of a tutorial that would help me get through that process.... I am either not using the right search terms or I am just too old to be good at this and should have stayed home when the rooting lessons were being handed out...
Anyway, I genuinely appreciate your help... Thank you so much !!
Ok I was able to pound my way through the nag screen to the settings menu and eventually got to the baseband and model #
baseband: L720TVPUBOA3
model #: SPH-L720
I have tried 3 times to download the only version I can find on the sammobile.com website using the baseband to search and the file fails to download after getting about 2/3 complete.... I have tried it on 2 separate computers from 2 different locations now...... This is horrifying ...... Every single force that can be working against me, is working against me.
Ugh...... If you have a link to a method I can use to force wipe the phone without a stock rom, but with a recovery I can boot into to flash a rom I have on my external SD card, I would love to see it...... im losing my mind here...
<<<<<<<< EDIT>>>>>>>>>
I was also able to pound my way into the settings menu and do a factory reset which removed the google play nag. From there I was able to root around in the developer options folder where I discovered that in order to be able to boot into recovery, you need to select the "boot options" tab and allow the device to boot into recovery....
I know this device is old now and most people have moved on, and I am pleased that there are some people who stick around here to keep this device alive. I only wish that someone would have advised me to check the boot options selection when I indicated I could not boot into recovery... That would have saved me 2 days of manic obsessive he11....... This was complete he11...... But I am on the other side of it now, and have reflashed another rom... I am back among the living.

Sprint phones have always been able to downgrade and thinking that has not changed. You should be able to Odin the last one listed on the link I gave you...NAE...then your phone should boot...you can then take the Sprint OTA if you like then root and recovery as normal. Then you can get to the stuff on your SD and flash. The only issues I remember popping up these days is if you mismatch the modem and OS...which wouldn't be the case if you Odin'd NAE.

Glad you got it fixed! I have had my phone for over a year now and never heard of a boot options tab. I guess you learn something new every day.
Also glad you got it fixed. But let's keep this open in case someone else has the same or similar issue.

Well not being able to leave well enough alone, I locked my phone up again.
Because I was able to get out of soft brick without needing a stock firmware, I never bothered downloading NAE from the link you provided.
Turns out after 2 separate downloads (one using Chrome and one using Firefox) I have determined that the md5.tar files on that site http://www.rwilco12.com/downloads.php?dir=Files/Devices/Samsung%20Galaxy%20S4%20%28SPH-L720%29/Stock%20ROMs are worthless.... BOTH downloads failed in Odin before I could even get out of the gate....
They failed the md5 check that Odin performs and would not allow me to continue.... IS there something I am missing?

Sweet baby Jeezes please tell me that is not all I had to do.... I spent 4 hours staring at the screen downloading files last night .... I waited 4 hours and finally could not stay awake any more but I finally got the OA3 firmware from SamMobile downloaded successfully. I left the .md5 extension and it is now flashing via Odin as I type this.... I could have saved myself a few more hours of misery if I had known you can remove the .md5 extension..... This learning curve is hard on an old man like me hahaha!
Thanks Kenny
<edit> Ahhhhh.... the sweet smell of success !!! I am now booted back into a stock phone!!!
Man I hope this thread can help save someone else from the anguish I have put myself through with this thing....

I am sure it will! Glad you got it working and glad I helped! Some versions of Odin don't care about the md5 extension and others barf it up. With the way your luck went....well...don't buy a lottery ticket this week...hahaha.
Tracfone version
I'm having no luck with Kingroot. It says no root available for device.
According to 'one-click-root' website, the device has no way of rooting it.
Is there any updated information?
.
device specifics:
model: SM-S920LZAATFN
android: 5.0.2
build: LRX22G.S920LUDU1APK2
hardware version: S920L.03
.
[edit: was hoping to change the title to reflect that this post is about the tracfone version]
TWRP recovery method?
TWRP recovery method?
I've read that a phone may possibly be able to be rooted by using odin to download a TWRP recovery, then booting into that new recovery using hardware keys, instead of rebooting normally. And this results in a rooted phone?
I think I have seen a TWRP that may work with this phone. Any help is appreciated. I'd like to be able to update this thread to include a step by step approach to this and other versions of the same model 920.
I'll continue to post updates as I discover more information.
DIY time : crash course in brain surgery
Ok, so I've read a bit of stuff in the forums on the SM-S920L, mostly about the StraightTalk variant, which apparently uses the same system rom, though I'm not so sure.
At any rate, rather than just throw carp at the phone and hope it sticks, I'm going to teach myself how to do it all myself, a-z, 1,2,3... etc., starting with making stock images of the various components, for recovery purposes. Perhaps the phone can be used as a TracFone again someday, though I have no desire to do so, having already bought another for cheaper that even works better, though not as fancy, just newer.
So, I'll leave it here for now and just update the primary with new information as I discover it, starting with the extraction of the stock images, hopefully without goofing up the phone, lol.
This is an unpopular phone, at least for hackers. But it will be a good tool for expanding my knowledge.
Any help appreciated, such as, 'Is this even necessary? There are files here here and here that will do it all'.
(lol, nope... so far I've discovered there is no root option, kingroot no work, etc. There seems to be no posts with information specifically regarding the TracFone 'variant' of this model. It suggests that i can use the StraightTalk files for it, which may work, but there are many questionable unanswered problems.)

Definitely don't use kingroot.
Do you have a laptop or pc? If so I can help you out. I have the same phone. Mine is straight talk, but it's sm-s920l a tracefone just through straight talk.

Ya I got the straight talk, I have been using king root but I totally bricked and wiped my phone on purpose because I wanted to start fresh and let it update. Having a problem though I used twrp and nuked all my ****, or so I thought. I'm trying to OTA update I'm currently on 5.0.2 and it's saying I have a system update and even after I checked everything to be deleted it still says error and one of my files is modified or some**** like that. I think it's like admin.prop so **** it. I do however want to go systemless root. What do you suggest is the best root and rom for our device?
To answer op question yes your phone is the same as ours. Mine even shows tracphone on boot.

Well for our phone there is only one custom ROM and it's LineageOS 13.0 https://forum.xda-developers.com/grand-prime/development/unofficial-cyanogenmod-13-0-galaxy-t3491494 It's android 6.0 and it can be rooted too. It's not being updated anymore for our device as far as I know. There is Lineage 14.* but not for our variant.
For systemless root you'll want to go with Magisk. https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445 I had Lineage, and don't get me wrong it's worth checking out, but I downgraded back to stock and went with Magisk. You can even get Xposed throughMagisk.
If I was you, I would flash back to stock. You can go to this thread https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445 and download the first two, Stock Boot and Stock Recovery. Make sure to unzip them because you need the md5 files they extract. I'd wipe everything again and then get into download mode. On your PC fire up Odin, I'm using version 3.10 http://odindownload.com/download/clean/Odin_3.10.0.zip Click BL use the stick boot md5 and then under ap use the stock recovery md5. When it reboots and you set it up do not turn reactivation lock on.
If you don't already have Magisk on your sd card get it on there and install through twrp. It will ask if you want to root. Might make a back up after. I always make backups and then transfer from sd to my pc. I can restore to like 6 different versions of my phone right now lol I'm no expert, I haven't been messing around with all this for long so I hope that all makes sense. :fingers-crossed:

Haha ya it does I just wish they didn't treat our phone like it has Ebola or some****. All kinds of **** for the other ones. I agree on the magisk because I really want to try that out. Alright thanks for all the helpful links I come to this site to find **** for ours and I end up looking at a bunch of cool stuff I can't have.
I'm waiting on the pixel 2 XL before I upgrade. We just missing out on too much stuff. I think magisk will keep me busy in the meantime though. Thanks again man I'm Soo add once I get here on all the stuff then I wonder well will this work or this work and by then just like awwww **** it.

Hey, I thought I'd let you know LineageOS 14.1 is available to us now. I can't find a specific thread on it, but you can download it from http://grandprime.ddns.net/jenkins/job/LOS_Builds/# Flash it with twrp. You will want to flash that and then flash open gapps [ARM - 7.1] and then whichever from here http://opengapps.org/ I did all that first, set it up rebooted and then installed Magisk.
It has Substratum pre-installed and it let's you theme it nicely. There is only an unofficial xposed version so far.
Anywho, thought I'd throw that out there.
thanks for the replies, gives me inspiration to keep on trying; the phone is pretty ho-hum with default stuff and the general blah blah of social media, etc.;
thanks for the tips, feel free to post more details as they come in
My Turn
I'm about to try and put 14.1 and Magisk on mine. Wish me luck!
downloading twrp recovery and rooting
in google search up twrp click on the first link then click on devices on the top right corner then search up your phone download the twrp.img.tar file
power off your phone and press volume down + home button + power button to boot into download mode
in odin select AP then select the twrp.img.tar you downloaded then press start
your phone will reboot then download the SuperSU zip file
then go to settings then go to find my mobile you have to get a samsung account then you will see reactivation lock option turn that off
then power off your phone then press volume up + home button + power button to reboot into twrp recovery
once booted tap the install option then select where you downloaded the supersu zip file swipe to flash it once done flashing you will see the reboot system option to reboot your phone
then your phone should be rooted!
Hi guys,
So, this is a last resort. I've followed a number of different guides and methods, but nothing has worked. The closest "success" I've had is with a Chainfire auto root; it flashes, it breaks Knox, but I still don't have SU. Could it be because I don't have an SD card? I saw it as a prerequisite in some guide but didn't really put much stock in it as that was a single mention which also involved loading it with verity, which I'm more interested in removing.
I've also tried twrp, which that looked like it had bricked my device, though I managed to recover it by flashing the auto root again. I'm speculating that it's something to do with the latest updates, but really I'm just clueless and frazzled after 4+ hours of wracking my brains. I'm not sure what other info you'd find helpful anymore without going full splurge, so I'll keep it sweet and let you question me or berate me for my vile, witholding ways as you see fit. Any help is greatly appreciated!
Edit:
My SU checker says that I've not got the binaries or root user account. The .tar from firmware.mobi is only 54mb. I tried turning off suhide, but changed no other options. Trying to use fastboot straight up fails, the device isn't recognised after adb booting (despite having tried the correct drivers and some random others multiple times over.) I've been unable to locate a release for the T585 on twrp site, though a version is out there on these forums from a year or so back.

So, this is a last resort. I've followed a number of different guides and methods, but nothing has worked. The closest "success" I've had is with a Chainfire auto root; it flashes, it breaks Knox, but I still don't have SU. Could it be because I don't have an SD card? I saw it as a prerequisite in some guide but didn't really put much stock in it as that was a single mention which also involved loading it with verity, which I'm more interested in removing.
I've also tried twrp, which that looked like it had bricked my device, though I managed to recover it by flashing the auto root again. I'm speculating that it's something to do with the latest updates, but really I'm just clueless and frazzled after 4+ hours of wracking my brains. I'm not sure what other info you'd find helpful anymore without going full splurge, so I'll keep it sweet and let you question me or berate me for my vile, witholding ways as you see fit. Any help is greatly appreciated!
Edit:
My SU checker says that I've not got the binaries or root user account. The .tar from firmware.mobi is only 54mb. I tried turning off suhide, but changed no other options. Trying to use fastboot straight up fails, the device isn't recognised after adb booting (despite having tried the correct drivers and some random others multiple times over.) I've been unable to locate a release for the T585 on twrp site, though a version is out there on these forums from a year or so back.

The only way I know of to successfully root a Tab A is by flashing TWRP and then using it to flash SU or Magisk. What version of TWRP are you using and what version of Odin? Using the correct ones won't brick a T585.
When I got my Tab A a couple of weeks ago I did a LOT of reading first ... but then it took less than 24 hrs from receiving it to having it rooted + running RR Oreo
Following the guide HERE I enabled OEM Unlocking and installed Odin.
Using Odin I flashed twrp-3.2.3-4-gtaxllte-OMNI6.tar from HERE.
Using the freshly installed TWRP I flashed RR-O-v6.2.1-20181210-gtaxllte-Unofficial.zip from HERE, Gapps from HERE and the latest Magisk from HERE.
That was it - rooted and ready to go :victory:
The first guide pretty much covers all the steps you need, I simply used a different TWRP version. You can't brick your device flashing TWRP unless you flash something that's not for your device. Make SURE to enable OEM Unlock first - and don't use SuperSU but Magisk.
Good luck :fingers-crossed:

I honestly don't remember
But it should work on either one - only difference now is that we have an official recovery that can be downloaded from twrp.me directly :highfive:

Does this need twrp-3.2.3-4-gtaxllte-OMNI6.tar to go from Oreo to Pie?
I am not finding -OMNI.tar anywhere. All links are dead.
Can I use a newer version of TWRP?
Thanks.

Ok, so I went ahead and tried with the latest TWRP (3.3.1.1), RR (v7.0.2).
Everything seemed to go well..... except, tablet is now stuck in boot animation. It won't startup.
I double checked and I don't think I missed any steps.... Any ideas on what I can try?
Thanks.

Update:
I tried to restore the backup via TWRP and ended up with a "unable to mount /system" error.
My /system partition was showing zero size.
Many wipes and restores didn't help.
Eventually, what seemed to help was to choose repair the system partition, change file system to FAT, change file system back to ext4. Saw it in a youtube video- https://www.youtube.com/watch?v=T-7neHzSIvc
After /system error was fixed, I did an install of RR again and it went smooth.
All is well now.
Hope this helps someone.

Back then we had no working official version and the Omni6 one was the only one without issues. Now we have the official and it should work just fine.
No idea why you had those problems, but I'm glad you got it all sorted
Hi All
Looking for a best tutorial to follow and the right one for my phone really don't want to brick it, obviously :/. as there seems to be a few versions for the S7
I have the following: S7 android 8.0.0 SM-G930F not sure what else I need to know! I'm in the UK so I assume UK phones come with Exynos cpu's
and as far as I am aware android 8 is Oreo! but when they say Stock Rom I assume they mean the same as what came with the phone the original rom?
if so is there an alternative stable rom without the crap included or is it just as simple to delete every thing you don't want now it's rooted! and does that mean if I reset the phone its back to normal with all the crap included! or is there a way to keep it rooted even after reset! and should anything be disabled I.e prepare the phone before attempting to root like any kind of auto encryption that needs disabling and just one more question
if at anytime the rooting process hangs for a ridiculous amount of time when should I throw in the towel! and what are the chances of retrieving the phone back to original state! or does a dirty shutdown brick it?.
I started the root process but failed at first hurdle!, followed instructions install Odin3_v3.13.1 but when I connected the phone nothing showed up in Odin? though I will have another go just to confirm I followed it correctly, I'll update this when it's done.
this was the tutorial I followed:
Easy 4 Newbie [Root Guide]SM-G930F, G935F, G930FD, G935FD (Samsung Galaxy S7 Edge)
Warning ! Please note that the official TWRP for Nougat on Galaxy S7/ S7 Edge is not available yet but based on my experience the Marshmallow version is working on Nougat. By installing a custom recovery on your S7 and S7 Edge and rooting it...

I know alot of questions I would really appreciate any help and clarification on the above.
many thanks

Look pal, rooting the phone is just like being an adult, it means you will get rid of Samsung's "Child Care".
Yes, UK models use Exynos chip, but you have to be sure, look at your baseband version, if it is G930FXXX, then you are good.
ROMs are in two shapes:
Stock-based: These are just like the one you are using, or other Samsung phones does, like Samsung Experience, One UI, TouchWiz. Maybe MIUI and FlymeOS will come into account, as there are ROMs based on them + Samsung's.
AOSP: These are pure Android ROMs, with few modifications to the core, but keeping the UI as close to the source as possible, Google & OnePlus phones come with a near-to-pure operating systems.
Changing a ROM is not risky, as long as you follow the instructions, without any unaccounted improvising.
Before you install a ROM, read the working and bug list, to make sure you are installing something you have an idea of.
You need to install TWRP recovery (or any other one you like), and format data, in order to be able to travel among ROMs and/or root your device.
Formatting is only required because the phone is forcibly encrypted, and TWRP can not decrypt it, at least not for this device.
Rooting is simply about flashing a 5-MB file, Magisk, then rebooting to system, no need to wipe data.
No need to do any additional steps, unless you are trying to hide root from some apps and/or pass SafetyNet.

Hi Mohamedkam000
Thanks for replying. I'm not confused about why I want to root the phone. I'm just trying to understand the inner workings and the risks as I'm not as clued up with phone OS's as I am windows. I don't care about warrantees or hiding the the fact it's rooted I just want a clean rooted phone free of big brother well inside at least I know you will never completely keep them out but making it hard is a start lol.
Thank you very much for all the above especially on clarifying about the roms and the reason TWRP formats due to encryption nice one
My Baseband version slightly different though it's G930FXXU8ETI3 not sure if having a U instead of a third X makes any difference!
and I posted wrong tutorial I'm actually following this one below again not sure if that matters.

It doesn't matter which version of Android you are using, root is the same.
However, on stock ROMs, it might sometimes get rough, as you may end up with Wi-Fi not working (happened to me Q1 2020).
If you really want to learn how Android OS works, then rooting the stock ROM is not your way.
Try AOSP ROMs, preferably start with Oreo ones, you can root in 3 common way, LineageOS SU Add-on, Magisk, Super SU.
But before you tickle your phone, you have to make a backup of your current device, of every partition, EFS is the most important partition, so make sure it is safe.
Baseband version doesn't matter a lot, unless you're paranoid with updates, it is sorted alphabetically, each string on its own.
The phone is more similar to a linux machine than to a Windows PC.
Edit: To root stock ROM, you have to flash dm verity, so you don't end up encrypted again.

Thanks again for clearing quite a few things up I thought rooting stock rom would have been far safer way forward wow how wrong was I! but I guess I am just trying to find any kind simile to windows in any way but as you pointed out again it's more like Linux which again I've only played around with ubuntu and mint for a short period so again not to up on Linux lol.
It's funny I was just reading up on AOSP ROMs then got your message. I see they have a stable but not complete! Android 10 not that I would consider it need as I need a stable OS so Oreo is fine for me.
I have backed up phone using Smart Switch on the PC I assume that copy's every thing that's needed, I reset the phone in anticipation all be it prematurely but at least it restored all my data so if anything that was a good test of the back up at least .
I will have look at some AOSP ROMs and see what's involved there, I'll check out their tutorial hopefully it will include the whole process including root.
I gather by your comment using a AOSP ROM you don't need to use dm-verity or will that still be needed!.
The first thing to do is to flash (install) TWRP, it's a custom recovery (think of it as a mini OS that can boot before Android), that will be the base for any of your future tinkering.
Here is the thread, read the FP carefully: [Recovery][Exynos] Official TWRP for Galaxy S7 (herolte)
Once TWRP installed, you can do many things:
Install addons like Magisk. Magisk is the tool you use to obtain root. Forget SuperSU, its outdated, and don't works in modern versions of Android.
Install a custom ROM (this subforum is the perfect place to find them).
Backup & restore an image of your current ROM (very useful).

AOSP ROMs are pure, you can't say they are not complete. They are complete, and what OEMs do, like Samsung and Xiaomi is just a customization that you can do, too.
It is preferred that when you take a backup, take it with TWRP, just to ensure you backed up phone's partitions, along with "EFS".
The root procedure on Android 6+ is done by patching the Kernel (boot.img), so unless you take backup of that, you cannot keep root.
There are stable custom ROMs, custom ROMs are meant for custom adjustments, however the stability depends on your phone, and the way you use it, you can compare AOSP vs. Stock and see the difference.
AOSP ROMs doesn't need dm verity, well, at least not if the developer did not mention the encryption part.

Some of the roms I have looked at mention external touch buttons at bottom of phone do not work or something else in the phone I'm just reading their comments.
I understand about the stock & custom rom's now that's not my problem at least not at the moment as I am miles away from choosing a rom! as I can't even get out the starting gate!. I can not get TWRP on my phone as the only way I can see to get it on a unrooted! phone is to use Odin but as I said Odin doesn't work at least not for me it does not see my phone. I would love to take a back up using twrp but that won't happen until I find a way to get TWRP on a unrooted phone. what crazy paradox is this!. you can't root phone without twrp installed and twrp won't install on a unrooted phone!. that makes perfect sense.

Does your phone allow MTP communication? I mean can you transfer files when the phone is turned on?
Does the phone show any notification about a usb connection?
If not, then you have probably a bad USB cable, at least, or you have a hardware issue that can go as deep as a burned charging port.
If yes, then either your USB cable is not as fast as the phone requires, or you haven't installed the Samsung USB Drivers on your PC.
Unfortunately, you cannot root your device without PC, at least not since Lollipop.

Hi
Yes I can transfer files.
Yes phone asks to allow or block file transfer and it ohone shows up in Devices and Drives list and I can access the phone directory and shows up as Samsung s7 icon.
I will try another USB lead but the one I'm using is new and wasn't cheap but still a possibility I have had leads that weren't suitable for other things I was trying so it is worth a try.
Thanks

When I downloaded Odin this was latest one Odin3_v3.13.1 though I have doubts that one version update will fix this issue as I did not see many if any people having my issue so they all used Odin and I believe theirs are fine even with older versions! but as I said Mohamedkam it's worth a try I will down load that version and give it a try.
As for the Samsung usb driver I believe that is where I got mine
SAMSUNG_USB_Driver_for_Mobile_Phones no version visible under properties on file version 1.7.23.0.
The USB connection seems to be fine I have uninstalled then re-download and reinstalled a couple of times.
I can transfer files no problem it shows up as Galaxy S7 Icon with card and phone drive inside.
I'll update shortly thank you.
Update:
I just went to try new Odin and whilst checking my phone have seen I have Offical TWRP app installed? I have no clue as to how that's got in there! as Odin did not show phone so I could select nothing!.
In the phone I open app and if i select backup existing recovery it opens and Select Folder tab and under that Selected Folder: /sdcard Filename: Recovery .img and at the bottom of screen Root access required.
I just hope it's installed correctly!. it is showing in playstore my apps as well just to confirm. if this is now installed what should I do next Now not sure what tutorial to start following.
I am just going to try the new odin and see if it picks up the phone back soon.
OK Seem that it now shows up in the new Odin. at least I think it has! in the log window I see this: <ID:0/004> Added!!
I didn't see that before.
Would be grateful if you could tell me how to proceed from here!
Correct, you don't need he latst version of Odin or the Samsung drivers, bit it was just to be sure.
You need to be in download mode, but before, you must have checked OEM unlock & USB debug in developer options (mandatory).

As I said the older version did not show any kind of data what's so ever and the phone was in download mode. phone displayed "Downloading" which I believe it says that even if it's not doing anything! so a tutorial explained. I think it must have installed the Official TWRP app even though phone did not show up in Odin everything was blank however when I installed the new version of Odin like you suggested it then showed up as <ID:0/004> Added!!. so your suggestion work thanks for that and I did enable OEM unlock & USB debug I did long time ago.
I would check out your tutorial but unfortunately I don't speak French and translating instructions is too risky but thank you for the offer but I'll carry on look around still undecided on what custom rom to go for as I said some comments point out small issues and the developers also state certain things are not working so that is making it hard to consider one if you know what I mean.
Again Thank you for your input very much appreciated.

Take a note that, when you flash TWRP, you have to boot immediately to the recovery, so as to enforce its existence, cause I remember they phone has an original recovery backed up somewhere, and gets triggered when you reboot directly to system instead of the unofficial binary.
I advise you to watch guides on YouTube, it's more .. understandable.

I recommend to go with ALEXNDR ROM: zero bugs, everything works perfectly (it's based on stock ROM).
[ROM][G930F/FD][ALEXNDR] * U8EUE1 * DevBase v7.4 * Encryption support [Jul-10]
Important notes for Developers / Chefs !!! This ROM is NOT based on any other custom ROM. My work contains many original ideas and innovations that I introduced as the first in the ROM development (see "Changelist" in post #2). Of course, it...

Take a note that, when you flash TWRP, you have to boot immediately to the recovery, so as to enforce its existence, cause I remember they phone has an original recovery backed up somewhere, and gets triggered when you reboot directly to system instead of the unofficial binary.
I advise you to watch guides on YouTube, it's more .. understandable.

Yer I read that but I've ended up with TWRP installed and did not do that process because I was unaware it installed until it showed up.
As I said I'll just keep looking for now I know I'll find one that works for me from start to finish.
and I've been checking youtube but wouldn't want to use any links their providing but it may help familurise myself with the whole process if i watch enough of them.
Thanks again for your help.

Hi Mooms
I will check that out many thanks. I wonder if you could help me here. I am in the middle of the rooting process but have hit a snag. again!
I have now installed TWRP successfully then no-verity-opt-encrypt-3.1 all went fine and I'm at point of flashing Magisk but have an issue when I swipe to flash is gives me a error in red saying "invalid zip file format !"
I downloaded it from github here.
GitHub - topjohnwu/Magisk: The Magic Mask for Android
The Magic Mask for Android. Contribute to topjohnwu/Magisk development by creating an account on GitHub.
github.com
I click on "code" tab and then "download zip" and I placed that in a download folder on my sd card when I select it I get the above error any ideas as to why I am getting this am I downloaded the correct file?
thanks for any assistance you could give.
Alrighty... So I'm in the weeds here after going through three variants of the Samsung JPop (Which have bootloaders locked up like Fort Knox) and decided today to break down and dish out $59 for this bargain device. First thing I did upon getting it home was fastbooting it, and was able to unlock the bootloader with no issue. (So easy, a caveman could do it)
I've read just about every thread in here and though there seems to be TWRP support for quite a few models of the Onn tablets, I didn't see this one in here. Right now I have a throwaway laptop which is installing ubuntu for building TWRP for this device. Now, I have NEVER built TWRP. But I have plenty of free time, ambition, and am willing to learn. I have the basic guide to building TWRP open elsewhere. I will take whatever help I can get on doing this, big or small. Building a basic TWRP image should be easy enough, but the guides don't really go into device specific details (as expected), so this is where I could use some veteran help.
Device Specs:
Model: 100026191
Out-of-the-box Android Version: 11
Display: 7" 1024 x 600 Resolution
Processor: 2.0 GHz Quad-core CPU
RAM: 2GB
Cameras: 2MP front & back
USB: Type-C
Ubuntu just finished, and I am getting the build environment ready as we speak. Will keep this thread updated with progress and hickups that may occur along the way. Wish this noob some luck!!!!
Alrighty, so here's what I've been able to come up with as far as more detailed system information. Sorry for the late post, had trouble getting wifi working on ubuntu but got it going.
I suspected a MediaTek CPU and was eager to do a readback with SP Flash Tool, but as you can tell from the provided screenshots, it's actually a Cortex-A53 CPU. my goal here is to some how pull my stock recovery out of here. I thought about dd'ing it but someone in another thread advised against it. Does Onn have stock firmwares hidden away in the internet somewhere? Or is there another tool I can use to pull recovery?
Good evening guys and gals. New day, new opportunity. So i'm still stuck at pulling off boot and recovery from this tablet. I used
Code:
/adb shell cat /proc/mtd
to no avail. Permission denied just like with dd.
Today, I got the MTK droid tool and hooked the tablet to it and got these results. Still no scatter file, still no progress on pulling these partitions. (I apologize for my dumbness yesterday, this device is in fact MediaTek)
Alright. Eighty of you have clicked in this thread, zero of you show any motivation to do anything to contribute. You guys must hate this tablet because I went through this entire board, and each thread that even mentioned this model were left with no response. I just want the boot and recovery partitions off of the stock tablet. I am willing to do the rest. I said before, I'd take any help I could get but since this device is "so" insignificant, I'm not trying anything else on it.
I don't know if you guys dodge this device because it's Android 11, or what. But the least you veterans could do is either tell us it's not going to happen (given that you tried), or give us some other ideas we could try. Hell I'll paypal you enough for you to have the device in your hands in order to help. But that's where I stand. Moderator can lock this thread if he wishes. There's nothing else I can do for this device at the moment.
guess i'll return it to walmart
was hoping to root it easily with twrp
just gonna go grab the 8' if this is how it ended for the 7'
thanks for the help though!
I need a firmware for the 100026191

I have the boot and recovery images if you want them.
I unfortunately accidentally deleted the original boot image, but I have a magisk patched image still present.
I can walk you through the process of extracting the original if you would prefer that, it's quite simple, I just don't feel like buying a second Onn tablet at the moment.
Just note that if you want to extract the original boot image, do NOT flash the Magisk image, it will permanently erase the original boot image. There is another way, I can walk you through it.

I oicked up one of the gen3 tablets. Do you think your way of pulling the boot image would work on it?

My way of pulling the images should work on any Android device that ships Android 8.0+, however if you got it brand new, don't update it.
Factory reset it if it downloaded an update, then disable OTA updates before enabling Wi-Fi.
You can run `adb logcat` while the update is downloading to find out where to download the OTA, and dump the boot partition from that.
From there, if you install Magisk, you can dump the recovery partition with `adb shell`.

Ok I will have to reset it then go from there. Do you have a guide on how to pull the image?

When doing first time setup, don't connect to Wi-Fi.
Enable Developer Settings
Disable OTA Updates
Enable USB Debugging
Connect to Wi-Fi
Connect the device to your computer
Run `adb logcat > ota.txt`
Reenable OTA Updates
Go to Software Updates and start downloading the Android 12 update (If it's not the Android 12 update, disable OTA updates again after this one finishes installing, then try logcat again after rebooting)
Search for a link that looks like `https://android.googleapis.com/packages/ota-api/package/827ee737174e0e8f761bcaeb12738221a924c810.zip` in the logcat.
Put the update link in your browser, and download the zip file.
Extract the zip file
There's your boot.img, very conveniently.
The update link I have provided is for the 100074181, the 3rd gen Onn 7, if you happen to have that one then go ahead and just use my link.
Though update to Android 12 before actually using that boot.img with Magisk, it won't work with Android 11.
After you're done with that, and you're rooted.
`adb shell`
`su`
`dd if=/dev/block/by-name/recovery of=/storage/emulated/0/recovery.img`
Then connect your tablet to your PC and enable file transfer in USB settings, then just pull recovery.img out of your tablet and you have the recovery image.

Update to Android 12 before using Magisk, just in case.

I will look for it. Saved it to a USB drive and of course it decided to be stupid and it is repairing now. Slow going but as soon as it gets done I will look to see if it survived and if so I will get it uploaded.
