How can I install a rom downloaded from here with odin? - Samsung Galaxy J7 Questions & Answers

Hello,
Currently My J7 got stuck on boot window, all i can i do is to be able to reach the download mode, therefore i downloaded a custom rom (this one: https://forum.xda-developers.com/galaxy-j7/development/rom-t3713641 )
But I can't flash this using Odin, I'm very new to this, so what's the problem? How can i install this rom using odin?

Custom ROMS are generally flashed via TWRP (or similar installations). Odin is used to fix issues using stock firmware. I'd Google search both in your case. If your phone is down, you may have to flash stock firmware (via Odin) first, then follow well documented root procedures for your device model number (I'm guessing it's the exynos J7 Tmobile or Metro PC variety judging from the rom you linked). First order of business would be correctly identifying your phone model, then proceeding from there. Happy hunting!

No worries. I know the J7 has a plethora of sub-model numbers, it can be a little confusing. Just be sure to get as specific as possible regarding your specific device. The J700T for example needs J700T firmware, even though it fits into that broad range of Exynos J7 (or J7 2015). Thats the only J7 I'm familiar with, just stating the obvious need for precision. Good luck with flashing!

[SOLVED] Root G930F running 6.0.1

Hi everyone!
I'm trying to root my G930F running 6.0.1. I downloaded the corresponding CF-Auto-Root from https://autoroot.chainfire.eu/ and flashed it using the integrated Odin. After that my phone didn't boot anymore. I got an exception from the bootloader (same as in this thread: http://forum.xda-developers.com/s7-edge/help/s7-edge-bug-t3331878).
Luckily I was still able to get into download mode. So installed TWRP and flashed SuperSU (http://forum.xda-developers.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770). Flashing SuperSU yielded some exceptions.
After a restart, my phone was working again and I was very relieved. Still the phone is not rooted. So I'm wondering what I am doing wrong, how can I root my phone?
Any help is greatly appreciated!
Did you enable OEM unlock in developer options first?

Wow, you are fast, thank you for taking the time! I used the Odin that came with the CF-Auto-Root. The file is called "Odin3-v3.10.6.exe", so I guess it's the wrong version. Do you think I should try again with the newer version? After the first attempt I'm a bit scared I could brick my phone.
Do you have a link to the appropriate Odin verison?
Just out of curiosity, do you know the reason, why it doesn't work with older versions of Odin?
As the phone is important for me, I tried hard not to be stupid and to follow the guides. I checked multiple sources, but I didn't come across the information about a specific version of Odin. Normally I use guides from xda-developers as they are good and reliable. The info thread links to the following thread for rooting: http://forum.xda-developers.com/galaxy-s7/development/sm-g930-exynos-cf-auto-root-t3337353
There was no mention of a specific Odin version. I'm not trying to blame my mistake on someone else, just trying to find out how I can prevent a similar mistake the next time.
Ok, found a credible source for the download: http://odindownloader.com/download/odin3-v3-12-5
Got there starting from https://en.wikipedia.org/wiki/Odin_(firmware_flashing_software)
I'm always a bit paranoid I could get some virus instead of the legit software.

I guess just reading through threads, not just the main post, and if unsure, make a post in that thread asking what you are unsure about before jumping in
This is my copy of 3.12.3
Code:
https://mega.nz/#!acoGhA7a!17OPP5A1g9d7-GxAqCbjXFpmYfO7CgAHNcaZxqEkOao
Not sure why older versions are not compatible, I assume newer phone model & new(ish) Android version = New ODIN version needed to support them
Make sure you use the latest version of CF -Auto Root for your model S7 too (G930F)
http://forum.xda-developers.com/galaxy-s7/development/sm-g930-exynos-cf-auto-root-t3337353

You are my hero! Now it works and is rooted. So the problem really was the outdated version of Odin that came with CF-Auto-Root.

Hi
If you are talking about this procedure , yes you can
F and FD are the same device , also in the thread is mentioned
This is for the International SM-G930F/FD/X, Korean SM-G930K/L/S, and Canadian SM-G930W8 Exynos models only! Do not flash on S7 edge or Qualcomm models!

ROOT & Stock ROM for SM-J727S Galaxy J7 May 2017

Hi guys,
I was hoping someone could help me out. I have rooted before (long time ago) but I can't seem to find a lot of information on this specific phone (SM-J727S). I have been searching online (and across many dodgy looking websites, thanks No Script!) and this is about all that I have found:
The Galaxy J7 is also known as the Galaxy Wide 2 in South Korea
http://pdadb.net/index.php?m=device&id=11601&c=samsung_sm-j727s_galaxy_wide_2
It was released on May 2017, runs Android 7.0 (Nougat) and uses the Exynos chipset
TWRP has a release for the J700 series but I'm not sure if it would work on the J727S
https://twrp.me/devices/samsunggalaxyj7exynos.html
The source code for the system has been released, but I couldn't find a stock ROM (which made me reluctant to try TWRP)
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=j727s
This is the closest I got to a Stock ROM but I don't trust the site, is this site trustworthy? (again, I came across too many dodgy sites to just download anything)
https://stockromupdate.com/2017/07/26/stock-rom-sm-j727s-samsung-galaxy-wide-2/
The KingRoot method currently will not work and is asking me to wait for an update (phone is probably too new to root?)
The closest thing I can find on this forum are these posts (but none reference the J727S model)
https://forum.xda-developers.com/galaxy-j7/development/root-sm-j727p-galaxy-j7-perx-td-lte-t3611202
https://forum.xda-developers.com/galaxy-j7/help/root-sm-j727p-galaxy-j7-perx-galaxy-j7-t3598117
So, I'm hoping someone could point me in the right direction. Thanks in advance
I'd thought I'd mention that the bootloader is unlockable in this phone. I had read elsewhere that other people cannot access the 'OEM Unlock' option on their version of the J7. It isn't the case with this phone
https://forum.xda-developers.com/galaxy-j7/help/galaxy-j7-pop-galaxy-halo-t3647805/page2
I also got a message from Google talking about my accounts being accessed by a 'J7 Pop'. I guess the Galaxy Wide 2 is also known as the J7 Pop?
So, I'm still on the track of rooting this device. I'm just gonna update any relevant stuff here.
The closest TWRP that I can find is for the 2016 version of this phone, it has the same Exynos chipset.
I'm thinking of trying this, but are there any problems with flashing the wrong version of TWRP? (Will I brick the phone? Or will it just error-out on recovery and boot normally?)
https://twrp.me/devices/samsunggalaxyj72016exynos.html
I also found (what I believe to be) the Stock ROM for this type of phone, you have to sign up to the site in order to download it. It is specific to SK Telecom (Korean telecommunications provider)
https://www.sammobile.com/firmwares/samsung-galaxy/SM-J727S/SKC/download/J727SKSU1AQD6/172065/
If someone can advise about going forward with the similar TWRP version I'd appreciate it. Cheers!
EDIT: Kinda answered my own question, from the TWRP download page https://dl.twrp.me/j7xelte/
Downloading an image for a different device, no matter how similar, usually does not work.

Any way to request an TWRP version?
I am Korean, and it's very hard It's angry me............................
XDDDD I'm from South Korea too and the J727S is customized with the Knox Enrollment Service that blocks the wifi and cellular data AND apk installization. (trying to uninstall it )
I found this: https://www.androidinfotech.com/2018/02/root-samsung-galaxy-wide-2-sm-j727s-nougat.html
anyone habe twrp for this model ????
Hi.. I've this model also.. tried to downgrade..but it can't..always failed
My friend was installing the twrp to root a J7 metal.
Now the cell phone does not restart, and I do not know what the **** it did KKkkkkkkkkkk
It wants to remove the twrp without formatting the device.
If installing the original rom by Odin using home_csc does it return to normal without formatting?
Restore

SM-G930A 6.0.1 unlocked running on T-Mobile flash to SM-G930T 8.0?

Hey guys,
My dad has a SM-G930A 6.0.1 unlocked running on T-Mobile. It is starting to show it's age (battery drain, apps not running like they should, etc.) and is still stuck on 6.0.1.. From my understanding, it should be possible to flash to SM-G930T, however I am a bit lost as to where to begin the process to do so. I tired going straight to 8.0 by flashing the SM-G930T 8.0 firmware files but this didn't work (I didn't think it would work, but it was worth a try). With that said, would it be better for me to just stick to updating to SM-G930A 7.0 via the guides posted, or is there a way for me to Flash the SM-930T 8.0 firmware? Thanks in advance.

Wow you guys really get screwed over there in the US with cell phones. It's a pain in the a** to do anything with your phones.
Anyway I'm guessing the phone was originally AT&T right? And now it's unlocked to any carrier.
If you just want to update the phone to the latest firmware then just flash AT&T Oreo. It won't affect the SIM it will still work as before.
If you want to flash any other firmware including T Mobile then you'll need to unlock the bootloader on the device and that's a whole different ball game. With plenty of guides on how to online.
Make sure you back up all the things you want to keep before flashing

Thanks for the reply! I appreciate the direction. You are right, US phones are a pain. And yes, the phone was originally an AT&T phone, but was unlocked.
As for unlocking the bootloader, I've found different sources that say that unlocking the bootloader on this particular phone is not possible with this particular phone. I did read something about an engineering bootloader being used to get around a locked bootloader for rooting. Could this be used for flashing as well?

That's not entirely true. Using Odin you can flash any USA firmware onto any other USA device, no bootloader unlocking required.
It's very common for people to flash G930U over their G930V/T/A/P devices to remove bloatware

It's unstable and only lets the device charge up to 80%, your best bet woulld just be a full flash with Odin
This guide is a bit dated but it's the best one out there. Just make sure you google the latest Odin and use all 4 firmware files when flashing https://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin

Thanks for the reply! I had tried flashing the 8.0 G930T variant last night with the latest version of Odin and the PrinceComsy version and got a Model Mismatch error. I read that the modified Odin3 v3.13.1_3B_PatcheD would let me flash the firmware and ignore the Model Mismatch error. However, I didn't go through with it because I was not sure if I would brick my phone and instead erred on the side of caution and made my post here. Would I be safe to flash the files from SM-G930T_1_20180625111401_xf3965l42p_fac onto my current device?
If your firmware files are from a trusted source like sammobile, updato or samfirmtool then it should be fine
Odin3 v3.13.1_3B_PatcheD seems to have positive feedback here on XDA so should be fine too https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572

Greetings-
I apologize for jumping in an already created thread, but I think I am in the same situation, and like to verify with you both before I use the advice please. I have a SM-G930T that I just purchased, and really like to run a custom rom. But I understand I can not because I have Android 8 on it. I know how to use Odin, and have the latest version plus you guys talked about it here. I have also already downloaded the stock rom from sammobile site. What are my options? Is there a rom I can flash the phone with using Odin that would provide better performance, less G..bage, and more battery life? Is there a way for me to root the phone? I really need an app that requires the phone to be rooted.
Thanks

Ok, so flash any unbranded Stock Rom for your device using this version of Odin which has been specifically modified to flash US devices. https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572 PatcheD.zip is the file you want to download.
Then when you have checked the phone is working ok on undrnaded firmware you can go ahead and root the device using this method which is again for US Qualcomm devices. https://www.****************/2018/0...on-galaxy-s7-and-s7-edge-on-android-8-0-oreo/
Take you time and read instructions.

If I understand it correctly there is no unbranded firmware for the US, its all network specific but you can flash unbranded UK firmware and it will work fine, UK BTU is the one you want from sammobile.
Load into the modified version of Odin and flash.

Yes that's the right one but like the beanvee and i have said there is a specific way to flash this stock then root the device.
You also need Samsung USB drivers installed so your pc can talk to your device, there's plenty of guides around how to flash with Odin and what you need to do beforehand, the only difference with you is the version of Odin your using and then the method of rooting afterwards.

Thanks. I have used Odin before, and I already downloaded the patchD version of Odin from the link. Thank you so much. I'll keep you posted on how it turns out. I still do not have a verified version of a custom recovery for this. Do you guys know of any? I found this link but the link to the suggested twrp does not work. I think it is this one. But I can not be sure. The original link points to a slightly different url.

Nope do not use that TWRP, it will flash TWRP but not boot it and you'll be stuck on Samsung logo forever.
There is still no way to unlock a Qualcomm snapdragon bootloader and i'm not sure anyone is working on it anymore.
All it means is you need to flash custom Roms via Odin or possibly the inbuilt S7 recovery, you just need to check the ROM is in a format which can be flashed that way.
With regards to finding a TWRP solution you'll have to do some serious searching on google and read everything.
There are already several de-bloated stock Roms on the forum if thats what you want to do. Root and custom recovery TWRP are two different things though, you get rooted so your good to go?

Yes root is my main goal, and you are right the debloated roms will work just fine. I can do w/o twrp. Just double checking here; since I am flashing the UK rom, and I believe one of the comments on this thread was how US images are locked tighter, would not I be able to find a UK version of TWRP for my phone? Just checking.

Now pull up a chair and listen closely.....99% of the American devices (including yours) have an extremely uncooperative Qualcommm Snapdragon cpu at it's heart and thus refuses point blank to play ball. The online community have done a fantastic job creating the modifications you are now using. The rest of the world (i'm happy to say) enjoy the S7 with an extreamly cooperative Exynos cpu at it's heart. It just loves to be fiddled with, it's a whore of a chip, constantly on the go with all kinds of neat tricks.
Anyhoo... my point is, the software has to be compatible with the hardware you catch my drift? All the cool little programs are written with a specific piece of hardware in mind, unfortunately for you guys Qualcomm is the ice queen.

Thank you so much. You guys are amazingly patient, and informative. Thank you for educating me, and helping me achieve my goal.
I have tried a few times but can not flash the files. I have attached screenshots, and followed the instructions here. Do you see anything I should be doing differently?
I initially thought the code came as one tar file, which I could flash, but it was a zip file, which I had to unpack.

SM-G930U root for v9 Bootloader "G930UUEU9CSA3"

i got the latest security update via OTA and an now running the G930UUEU9CSA3 firmware, ive tried flashing the eng boot img i originally used to root from here "https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616" but odin fails every time, i'm pretty sure its because the new security update updated the bootloader also... to version 9. now i guess my question is are there any eng boot files for the v9 bootloader available yet? or any other usable root methods available?

That wasn't very clever was it.
Should never update branded unless it's to fix a major bug. Any loophole which allows root or flash is closed on an update until someone figures out how to root on the new boot loader.
I think the best advice to anyone on US networks is to flash unbranded and go from there.

i got the latest security update via OTA and an now running the G930UUEU9CSA3 firmware, ive tried flashing the eng boot img i originally used to root from here "https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616" but odin fails every time, i'm pretty sure its because the new security update updated the bootloader also... to version 9. now i guess my question is are there any eng boot files for the v9 bootloader available yet? or any other usable root methods available?

Get magisk.zip from internet , move to a sdcard insert sdcart to s7, Flash twrp for s7 then format data then click install magisk.zip reboot after finish and done.

I'm fairly certain that the only twrp for the s7 is a temporary one because there is no unlock for the bootloader, and even still the temp twrp is only compatible with the v4 bootloader and I am currently on v9.... that is unless I'm mistaken if I am then please someone correct me and point me in the right direction because I'd love to be running magisk on my s7 : )

That wasn't very clever was it.
Should never update branded unless it's to fix a major bug. Any loophole which allows root or flash is closed on an update until someone figures out how to root on the new boot loader.

No it most definitely was not very clever at all and unfortunately I'm stuck : / Also is the G930UUEU9CSA3 firmware not unbranded?

Yes it is I didn't read properly. Anyway what odin are you using to flash? The modified one?
We are talking about a qualcomm device yes?

Yes I'm using the modified Odin and all my previous attempts at flashing the eng boot files via Odin on the v8 bootloader have been successful, it wasn't until after the OTA that I started having issues.
And yes this is Qualcomm : )

Hmmm so it may be that loophole is now closed, what you need to think about is if you deffo need root? Or is it just nice to have. I'm sure a dev will get round it soon.

Twrp will work certainly, i did on my own s7 qualcomm variant with this https://www.google.com/amp/s/forum....de-how-to-root-android-8-0-oreo-t3840271/amp/

Okay I was completely unaware of TWRP being an option or the possibility of Magisk with a locked bootloader, now to clarify I'm running the latest unbranded US Region firmware for the US T-Mobile version of the Qualcomm Galaxy S7 "(TMB) G930UUEU9CSA3" that being said I have a few questions about how to specifically to proceed if you don't mind helping me?
First is the version of Odin available from the post provided above inst the modified version I've been required to use for all my previous flashing "Odin3_v3.13.1_3B_PatcheD" should I use this one or the version provided in the post above "Odin3_v3.13.1"?
My next question is that all the different versions and variants of TWRP available for my device the Galaxy S7 and the S7 Edge are either for Exynos Canada/International or Korea or the Chinese Qualcomm variant of each. Should I download and use the TWRP for the Chinese Qualcomm S7?
The sammobile link in the original post for "Android 8.0 Oreo Stock Rom" provides me with a list of the latest and up to date international versions of firmware for the Galaxy S7 Edge "SM-G935FD" I'm assuming I should just use the stock firmware image for my device "SM-G930U" instead?
The link for the no-verity-opt-encrypt-6.0 is dead but I don't think its needed because of something someone said in the original post about this method failing after latest security update "the one I'm on" https://forum.xda-developers.com/showpost.php?p=78115895&postcount=18 he said he solved it easily with information and another flash able zip from this post https://forum.xda-developers.com/showpost.php?p=77000849&postcount=47 and the zip from here https://forum.xda-developers.com/showpost.php?p=76564735&postcount=37
All that being said I haven't attempted anything yet, I'll try the above method as I understand it later this evening and I'll post my results

Hello there, i deleted most of your post because i didn't want my post to be huge. So if i just give you some guidelines hopefully you can have a look around for the files you need.
1. For Qualcomm / snapdragon devices you must always use the patched version of Odin you already have. Now this version of Odin can be dangerous if you don't flash the correct firmware for your device because it ignores device mismatch and other safety measures the normal Odin checks for before flashing. Which brings me to.....
2. Anything for G935 will not work for G930 including TWRP, you must always use firmware, patches twrp which specifically says it for G930 Qualcomm/snapdragon devices.
3. The China/ Korea Qualcomm/snapdragon devices are exactly the same as the US devices, anything working on the China / Korea devices will work on the US device.
Now i know you want to root unbranded on V9 but as you are on the T Mobile network it may be easier to flash and root T Mobile Oreo for the time being until there is a workaround root for V9 unbranded.
All of the threads you linked to were for G935 devices and i've mentioned you can't use those patches BUT the process and step by step instructions you follow are the same for your device. So you can follow those guides as long as you are using the patches for your device.
There is a Snapdragon section on this forum so thats a good place to look.
I've had a quick look for this specific firmware and can't find anything about rooting the U9 version yet.....
I'm just checking this firmware G930UUEU9CSA3 your running did have either XAA or USC code next to it when you downloaded? I've noticed Verizon, AT&T and Sprint are using the same firmware VZN, ATT, XAS.

I'd be interested to know how this turned out if the device with V9 bootloader could be rooted with temp TWRP method.
Can i actually flash magisk on my 930u?
Is there any way to root my g930t ?
I'm on v9 bootloader, and i don't care about knox tripping.
Did developpers really failed to break the security of this little old device ? Or no one worked it ?

Would this info be applicable to edge models as well? Pretty sure our moderator has moved on as he is disgusted with samsungs persistance in blocking root with new bl versions. Im on an unlocked tmo s7 edge with the u firmware as well.

Yes by using 1st and #1623 post number it can be rooted easily. I already have done that on both G930P and G930U.

Help needed with S7 downgrading from 8.0 to 7.0

Hi all, I'm relatively new to the Android world and seeking help from experts here.
I recently bought a used S7 (SM-G930K), it came with Android 8.0 and I want to downgrade to 7.0.
I tried downgrading using its stock firmware with Odin. Attempted many times but only realized that it can only be downgraded as far as the bootloader version goes.
Think my S7 was on bootloader version 2. So as checked for the available stock firmwares, the "earliest" version 2 was still on Android 8.0 (PDA G930KKKU2ERJ1 and CSC G930KKTC2ERJ1).
Anyone can advise me how to go about downgrading to Android 7.0? Though this S7 may not be my primary phone and there's obviously no warranty, I won't want to brick anything.
Do I have to downgrade the bootloader version to 1.0 first? And how do I do that?
Apologies, do excuse these noob questions, I'm not familiar with many Android terms. Cheers!
Model: S7 SM-G930K (KT Telco)
Android version: 8.0
Baseband version: G930KKKU2ERJ1
Security patch: Oct 1, 2018
Basically, on Samsung phones, once you upgrade your bootloader, they put a lock on it, so you can never downgrade it, for security reasons, of course.
The only thing you can do is flashing custom rom, or stock rom with custom recovery & kernel.

I see, now i understand why..
"Custom roms" - does this mean it's made by users like us? And what does "stock rom with custom recovery & kernel" mean?
Can you point me where can i find these roms for my S7? Is it the same as flashing them on Odin?
Many thanks!
Yes custom ROM's are community made. The kernal is kind of like the foundation that sits beneath the ROM, so you can use the official ROM but run a custom kernal to tweak phone behaviour.
Flashing ROM's involves using TWRP instead of Odin. If you're going down that path I would recommend you read very carefully and educate yourself, instead of just gung ho'ing it. Wouldn't want to brick your device.
It's also worth mentioning while you can flash an older custom ROM via TWRP, that doesn't downgrade your bootloader with it. Having a newer bootloader on an older ROM can cause issues.
Most custom ROM's are also made for G930F, while some also support the G930K you may want to make sure before flashing anything.

Definitely will be more mindful as rooting does involve some kind of risk of bricking my phone.
Wow that's great info, really appreciate you explaining this to me.
Something new I've learnt! :good:
