[Q] Galaxy S3 Unknown ROM

Hi everyone, new android user here! I'll try to make this as brief as possible:
Recently purchased a used Unlocked Galaxy S3.
Currently using Bell Carrier on it and it works fine.
I noticed that even after restoring SuperSU was installed.
Checked download mode -> odin installed with custom binary
Checked to see if the phone has root access -> it does not
I wanted to try and flash it with a official ROM to completely restore factory settings but I don't know what the original carrier is so I don't know what ROM to download. I called a couple carriers but they have no record of the IMEI.
I'm fairly new to android and my past two days of google searching hasn't accomplished anything relative to my problem (although I know a lot more about the rooting community!) so I thought I'd ask here.
Is there any way to know what's going on here?
Can I restore the phone to factory firmware/ROM/etc.?
Here is some phone information:
Model: SGH-I747M
Android Version: 4.1.1
Baseband: I747MVLDLK4
Kernel: 3.0.31-538866
Build Number: JRO03L.I747MVLDLK4
Any help would be greatly appreciated!

Just go and download this program http://www.samsung.com/ca/support/usefulsoftware/KIES/JSP
Go to Tools > Firmware Install and Initialization
It will ask you for your model number and Serial number. It will use those to determine what stock ROM is correct for your phone.
It will then flash you to stock, just as Odin would, including the stock recovery.

It definitely looks like you are on the stock Jelly Bean firmware from Samsung. I747M is the Canadian model (747 is ATT). Your build number also looks to be the stock 4.1.1 based on the DLK4 build number! Just as the last guy said, grab kies or use Odin to go back to complete stock if you are not happy with what you have now. If your phone is showing custom binary flashes and you want to get rid of that, give Triangle Away a try! Good luck. :good:

Thank you! That worked like a charm! The device is now in a "normal" state and the binaries are "official".

Thanks for the advice! I'm not too concerned about the flash count, that's only really important your warranty to to be valid, right? But I'll look into it, it may be worth it anyway.
Thanks again everyone!

[Q] Unflashing Sprint Samsung GS3 SPH-L710! Help!

So I have a Sprint GS3 that I flashed to page plus, literally 1 day before they started running the Framily promotion that is $25 for a line, with no contract, and the kicker you can activate a phone you already own (just my luck). So now that it's flashed I'd like to unflash it at the end of the month, and reactivate it on Sprints network.
Prior to posting this thread, I've scoured the internet for different ways to unflash; and I've decided on this method bit.ly/S3Stock . It seems like the easiest way, me, being a noob, so I won't mess up the phone.
My problem is:
When I go into Download Mode on the GS3 it doesn't show the flashing? or do I just not know what I'm looking at? On the video Custom Binary says Yes and 1.
It says:
Odin mode
Product Name: SPH-L710
Custom Binary Download: No
Current Binary: Samsung Official
System Status: Official
Qualcomm Secureboot: Enable
Warranty Bit: 0
Bootloader AP SWREV: 1
I also installed a root checker, from google play, and it says the phone is not rooted? Does this mean that I can simply Factory Data Reset to remove the page plus settings?
I am running 4.3 in the android version, baseband is l710vpucmk3, hardware version is l710.14
In download mode it did not say anything about Knox, which was the warning on the bit.ly/s3stock link. Please let me know what I should do to get back to Sprint settings?
I really appreciate the insight!!!

My guess (and I am no expert) would you need to root the device, and if this phone originally was a sprint phone, I don't see why this would not work, download the newest odin and flash a custom recover. I recommend CWM or Philz Recovery, then flash the sprint modem which should get you back onto sprints network and remove the flashed modem for the service you have now. Again I'm not an expert so this might not work. Once you get rooted and have a custom recovery make a back up! This will save your but if anything goes wrong.

I was hoping since it was showing Samsung official in download mode I could just factory data reset. I'm afraid with all the multi step programs, files, I'll mess something up. Btw knox is on the phone. Doesn't give me the option to uninstall either...I might be better off paying someone who's comfortable using Odin and has an idea of what files they're looking at...

[Q] Just got a used SGH-T999L. Many questions. How to proceed?

Hello guys
So a friend of mine gave my his phone.
This is the information I get from it:
Model Number: SGH-T999L
Android Version: 4.3
Baseband version: T999LUVUBMK4
Kernel version:
3.0.31-2106417
[email protected] #1
Build Number: JSS15J.T999LUVUBMK4
SE for Android status:
Enforcing
SEPF_SGH-T999L_4.3_0010

I've been reading tons of threads and I'm almost ready to root the device but I'd rather ask before doing anything.
1. Can I root this phone as it is? Can anyone point me to the correct thread for this particular setup?
2. I've been reading about KNOX and the "warranty bit" but I'm not in the US so if this "warranty" is just with T-Mobile, then I ready don't care if it's tripped or not. Unless tripping this bit means something else...like, will it prevent me from future rooting, flashing, etc?. Phone is unlocked by the way.
3. I'm pretty sure this 4.3 version was done OTA. I can see an icon that says KNOX (when I click it, it says something like: "click here to install").
4. I'm guessing that there is no way to go to a previous android version, correct?
5. Can I flash the device with a stock 4.3 without KNOX now that I already have 4.3 OTA with KNOX? (presumably since I do not know how to check for it)
6. So what are my options? For me stock rom + root is fine. So again, if someone can tell me the correct thread for my phone, I'd appreciate it.
7. If flashing to docholiday's rom is possible, then I presume I need TWRP or CWD. I'm familiar with TWRP since that is what I have on my Kindle. Do they basically do the same thing? Any advantage of one over the other? Which version? I see so many on Docholiday77's repo Is this the correct one for the T-Mobile T999L: TWRP_d2tmo_2.6.3.1.zip?
8. At this point, any custom recovery I use (TWRP or CWD) will trip the warranty bit. correct? What if I use GooManager?
Is this pretty much what I have to do?

Sorry for so many questions, but as you can imagine... you can only brick your device once!
Many thanks!
PD: If you guys need for information, please tell me how to get it and I will post back.
EDIT: Ok, more info
ODIN MODE
Custom binary download: no
Current binary: samsung official
Qualcomm secureboot: enabled
Warranty bit: 0
Bootloader RP SWREV: 1

Cool. I soft bricked my phone when ODIN gave me some sort of error.
Trying to fix with Kies.
Back to square one.

Ok, nobody is helping so I guess I will tell you guys my findings.. maybe it helps someone else.
I tried using ODIN with Windows XP on a Vmware guest image on my MAC.
Something obviously went wrong with the usb communication between guest and host computers.
I tried flashing now with ODIN on a "real" Windows XP computer and it's working (half way through flash).

Galaxy A3 FRP Unlock

Hello.
I've just discovered that I can't switch my phone on because it says "custom recovery block by frp lock". I know there are numerous threads on this forum and other websites describing this problem and ways to solve it, included mantaining data.
Every method requires the download of the same version firmware you had installed on your phone. The problem is that I cannot really remember if I kept my Galaxy A3 2016 to 5.1 or I upgraded it to 6.0. Obviously I cannot check it by phone since I cannot even boot, nor via adb since it isn't able to recognise the phone in the download mode.
So firstly: is there a way to retrieve the firware code, or at least, the android version of my phone? Can adb recognise the phone in downlaod mode?
Secondly. According to this link in xda, that user was able to solve the problem using some kind of firmware image (QB1), which seems to be an upgrade. Is that method valid for other samsung phones? For my A3, should I follow the same steps with the correct firmware version?
Thanks in advance

Kies cannot link to the device in the downlaod mode unfortunetely

try using smartswitch and see if it detects it
-are drivers installed
-does the pc recognize the phone ?

So, I had already tried with Smartswitch, but it says device not supported and does not link at all.
Moreover yes, the computer could read the phone before the frp lock, and even now, odin can detect it in download mode.
Kies just loads for some minutes and then says "unable to link to the device"
EDIT: no sorry kies raises "the device does not respond"

ok we need to flash using odin , i assume you can't access recovery but if you tried and it worked, look at the top of the screen it must show a code like
<your A3 model> followed by <your country> followed by <frimware date>
If you couldnt, we can use an updated version for your model , please provide us with the model if u can.

I can only acces to odin mode. Via that, I have the following text:
Product name is: SM-A310F
Current binary: Custom (it was rooted)
System status: Custom
FRP LOCK: ON
Secure Download: Enabled
Knox Warranty Void: 1
RP SWREV: B:2 K:0 S:0
I am sure that the phone had Vodafone pre-installed applications, and looking at mrcrab.net there exist these possible stock firmware:
Android 5
Android 5
Android 6
Android 6
I only fear that if I mistaken the version I will obtain a wipe of my data, which are not vital but are important to me

Actually there is no way to avoid the reset as we don't know anything about the PDA version, install the drivers type in google "USB Samsung drivers"
It must show developer.Samsung.com/....
I'm on phone so I can't provide it as a link, install the drivers and try again, else we will get the latest version

I already have samsung usb drivers, and odin can succesfully detect the phone in download mode; Kies cannot, though
Anyway, if you open one of the links I posted, isn't the PDA shown in the line:
OS Version : A310FXXU1AOLE (chosen one as example)
In that website there is every stock firmware by model, android version, and mobile operator. I know two out of three, and those 4 links are the 4 possible choices regarding android version. If I picked the right one, would I avoid the data reset, wouldn't I?
EDIT: What, if I did how it is explained here with the latest version? I mean download android 6 last upgrade, extract it, rename .tar.md5 in .tar and flah it with odin? Would it be any risk of loosing data?

Hello,
.MD5 lets odin checksum the rom loaded to it to make sure it's not corrupted, however if you are sure of two main things:
that the frimware you are flashing isn't a downgrade as downgrading flashs a old bootloader which gets you in some kind of troubles possibly a brick, to avoid that, grab the latest version
and the second thing you must make sure of is that the file isn't anyway corrupted.
if you think it's all ok, then you can proceed as of i tried it once and it saved a device.

Okay, I'm sure now that my android version was 6.0.1 because I read that 5.1 didn't have single app permissions manager, and I definetely remember that I had it.
According to this page, I have three possible choices.
1) I think the right version is the oldest one. In case I mistaked, would I risk a brick even if the major version is the same?
2) Also, if I mistaked, do I risk a data loss even though the major version is the same?
Thank you (we're almost there)

The build number must be the same regarding the android version, so to keep the files it must be the same as the one in the phone, else a wipe will be performed.
The problem is that you want your data, that maybe lost if we don't have the exact same build.
Just grab the latest marshmallow or nougat -, but the data would be lost then.
Do a hard reset in case something went wrong.

I was able to unlock the phone a mantain the data! Thanks

I have a special problem with an old Samsung Galaxy A3 2016 SM-A310F (Android 7.0 Nougat)

I am not an expert, but it sounds like you are trying to flash a bootloader that is an older version than the version 4 on your phone. I don't think you can downgrade the BL version. The fifth character from the end is the BL version. (e.g. G955USQU4CRE1) Also, you may need a newer version of ODIN.

so could i just google a "verison 4 BL for s8+" or something along those lines?

Yes. There are a lot of software versions available. If you use Updato you can search by model number and service provider (listed as region on Updato. I was able to find one with a version 4 bootloader. Similar to your version, but CRE9 at the end. It is an oreo version. Your phone is a model SM-G-955U when you search there. It might take a long time to download. I have sometimes had luck speeding things up by trying to restart the download. Sometimes it just takes a long time. Be careful when you are flashing if you have any desire to go back to a previous version. I am not sure of the limitations.
Another thing you could try that might be easier for you is to go to the JRKruse ROM thread here - https://forum.xda-developers.com/verizon-galaxy-s8+/development/rom-t3771206 and use the instructions he has there to install the ROM. There is another rooted ROM that he has that may also work for you. He has instructions on what to do.

Hello, my galaxy s8 is stuck in rpmb provisioned and its boot looping, I can get to download mode, it doesn't say things such as fuse blown etc. How can I get out of the boot loop? Help is appreciated.

Did you find a fix? Im having a very similar problem. I don't see any stock roms with a v4 bootloader. The most recent seems to be a v3.

Fixed it the way Smithfolk said. I was using the combination rom FA70_G955USQU4ARE1 with a V4 bootloader. I used odin v3.13.1 and flashed verizion G955USQU4CRE9 from Sammobile including the bootloader and it fixed my phone.
