Phone reboot loop. Help find the correct firmware - Samsung Galaxy S7 Questions and Answers

Hi,
I have a Samsung Galaxy S7 that's causing all kinds of issues. Originally it had google FRP. After watching some videos on youtube, I installed combination firmware and after enabling developer option and flashing with some firmware, phone booted, started setup but halfway though the initial phone setup, it will power down and reboot to the same point. Tried various firmware but same result each time. I somehow think I still haven't loaded the correct firmware. Need help identifying which firmware I need or if there's something else.
on the back of the phone, it has SM-G930UZKAX. When I loaded this combination firmware (may not be the correct one), in about phone, it shows my model is SM-930V! Not sure why it's different than the sticker. Please advise how I can obtain the PDA, CSC, etc so I can get the correct firmware.
Much appreciate any help.
Thanks

how do I copy stock image/rom s7(snapdragon)

I am buying a new cricket wireless galaxy s7(snapdragon) and to fix the one I messed up. I want to know how do I copy the stock image/rom from the new s7 and put it on the old s7. Obviously they are both snapdragon models and they are NOT ROOTED. My old s7 just reboots and reboots I can get to recovery mode and the download mode. It only boots up to the samsung galaxy s7 screen before it reboots again and again etc. the reason is because I tried to root it with the tutorial on the unlockr's site the name of the article is "how to root the samsung s7 & s7 edge (all snapdragon versions) (video)" rooting the snapdragon s7 which broke my phone so all it does is reboot. Any help with backing up my new s7(snapdragon) and uploading the stock rom/image to the old s7(snapdragon) would be greatly appreciated.
Did you try downloading an image of a stock rom from updato.com or samfirmware etc.?
If not, download it, aswell as ODIN 3.12.3 and do a complete reflash (BL,AP,CSC,CP with re-partition checked, it includes a loss of data though).
You could try AP, BL and CP only and don't tag repartition, which won't wipe your device, if you are interested in your data. If you extracted your data, a full install mentioned above is recommended though. Just to get back to a clean image and anything your root might've messed up.
It should revive your old device and you probably don't need to buy a new one. Especially if i read correctly, just for extracting a stock image, which can be found on the internet already.
Given that you might already have triggered Knox, which will probably void any warranty from Samsung, you could try re rooting or leave it stock, which should be running good on Snapdragon still.
For other G930AZ Cricket Users I went through the samething. I used odin to flash the Engboot and then the phone just kept rebooting. To fix it I did the following.
The first step is to get the G930AZ stock image using samsung switch Here.
NOTE: Using the samsung switch Emergency Software Recovery to return to stock did not work for me, but I was able to get the stock firmware from it.
The model number is SM-G930AZ.
To get the serial number (took me forever to figure this out) go to the download mode on your phone (hold the power, volume down, and home buttons) and press the home button. The S/N is the serial number
After getting the firmware flash ONLY the BL, CS, and CSC (leave out AP) using this version of odin
http://www.mediafire.com/file/2t2sjqxtogbkafk/odin_3.12.3.rar
If that successfully flashes then things are looking good. The phone will restart and probably still boot loop but thats ok. Go back into Download mode but this time Flash the BL, AP ,CS ,CSC (Include the AP). IT should flash successfully and everything should be back to normal after that.
I was able to repeat this process twice with my G930AZ cricket phone so hopefully it works.

[Resolved] Galaxy SM-G355M Soft Brick, after installing Firmware with Odin, Boot Loop

Hello: I am in Colombia. The phone was purchased Used. I believe the phone was originally configured for Claro in Panama and that it then had Movistar Argentina Firmware flashed into it. I am a "Newbie" with Flashing, etc.
It was Unlocked and yesterday I Rooted it and it was working OK, but the Firmware was from 2014 and could not be updated via OTA or by KIES. My goal was to get Firmware that could be Updated and hopefully that was Unbranded.
I included the URL on SamMobile.com for the Firmware I flashed. I chose that one, hoping that it was Unbranded and I chose COL because KIES showed the previous Firmware ending in COL. That is apparently prohibited by XDA rules for new posters, but it is the latest one for Colombia for COL.
After Flashing the firmware with Odin the first time, and then the phone rebooting, I saw a message about 90 Android Apps updating. Then, it got to the Home Screen, which looked normal. However, if I tapped on any of the options (Settings, Phone, etc.) there was no response, as if the Screen was not receiving input. After rebooting several times and doing a Hard Reset, the issue continued.
THen, I Flashed that Firmware with Odin again. This time, there is a different symptom. After it boots, it will eventually get to a "Welcome" screen (in Spanish) where I am given an option (in Spanish) to select the language, which is shown as U.S. Spanish, or to select Accessibility, or to Continue, but if I tap on any of those options, nothing happens and after a few seconds, it again reboots. It is now in that loop, continuously.
The Wipe Data/Factory Reset option did not help the issues the phone is having.
When the phone boots, there is a momentary screen that shows "Tigo Smart", so this is apparently not an Unbranded Firmware that I was hoping to get for the phone.
The phone is in a "Boot Loop" as I am typing this post.
Questions: Is there another Firmware that you would recommend I get for this phone? Which Firmware? If not, how can I get the phone to work properly again?
After the first Flash of the Firmware, it got to what I call the "Home Screen" and looked as it did before I Flashed this FIrmware, but when I tapped on things, there was no response.
Thank you, in advance, for your time and your help, which I sincerely appreciate! Lanny
P.S.
This is my first post here. Please move this to another place, if that's appropriate. I cannot post this in the forum for this model, because it is my first post here.
Follow on with additional information
Before I began working with the phone, I noted the "Baseband Verson" is G355MUBU0ANJ2.
The first Firmware I downloaded from SamMobile did not have "UBU" in the PDA.
I downloaded another "COL" firmware for Colombia from SamMobile that does have "UBU" in the PDA.
I flashed that Firmware and the phone is doing the same thing it did with the first Firmware I installed (after I flashed it the 2nd time).
It is getting to the "Welcome" screen (in Spanish) and then if I tap, to change the language, or on another option, nothing happens.
Also, it is in a "Boot Loop" again.
I have my fingers crossed (and will pray) that someone here can tell me which Firmware I should get for this phone with a "Baseband Version" of G355MUBU0ANJ2
Thank you again, for your time and help which I greatly appreciate! Lanny
Solved by Flashing original 2014 Firmware
That was not how I hoped this would turn out, but the phone is working again. I installed the original Firmware, which is for Claro in Panama and is dated October 2014. I lost all of the changes I had made, but I will be able to get it back to the way I had it, in the next day or two. If anyone knows how I can Flash a much later Stock Firmware in this phone, that will work properly in it, please let me know. Thank you!
P.S. Someone had installed Movistar Firmware in the phone before we got it. I think it was for Movistar in Argentina. We are in Colombia.

newbie seeking help: which rom and how

greetings,
I recently inherently a Samsung Note Edge (SCL24). The phone is showing its age. It is on its default rom (4.4.4) but many things aren't work. For example, it is extremely slow; it won't remember wifi passwords, etc. I am hoping that by flashing a new rom I may bring it back to life.
The spec is listed below:
SCL24
Adroid 4.4.4
Baseband: SCL24KDU1ANJ3
as I am browsing through this forum, I am a bit confused as to the flashing procedure. Assuming it is the same as every other phones I have flashed, I suppose I would need to root it, install a recovery, possibly a new basebank, and then a new rom.
Is there a guide as to how to do this for this particular phone? It has been a while
any help, and suggestion as to which rom to flash, would be very much appreciated.
ps. I am not looking for anything fancy, but in the past I've always used slim rom.
regards,

Try a factory reset first.
done that many times
This phone was purchased in Hong Kong and other than the model number "SCL24" I couldn't find any other information. Judging from this forum, looks like there are many variations on this phone (vendors in North America, Japan, and others common in south asia). Also from this forum I realized that I probably need to update the baseband in order to flash any new ROMS (post kitkat).
Hence I seek your help,
regards,

Interesting.
Is this an international phone?
I tried asking about custom ROMS for my phone (don't want brick it) and didn't receive any responses.
I did do a Google search and didn't find much of anything.
I did download Marshmallow from Sammobile and have been gutting pretty heavily.
I guess after this much time, interest is fading.
problem solved, for now
As I mentioned earlier, this phone was purchased in Hong Kong and the model number was listed as SCL24. Following the thread on Project_ECSTASY (https://forum.xda-developers.com/no...rojectecstasy-custom-rom-galaxy-note-t3545658), I managed to flash the "Global edition stock rom without any bloatware from carrier au" using odin. The step I followed was:
1) installed samsung USB drivers for the phone (directly from samsung website),
2) downloaded and executed Odin,
3) rebooted the phone into Odin mode (vol down, home, and power),
4) connected the phone to computer via USB,
5) updated the rom through Odin.
6) once the phone rebooted, factory reset
I have not had much opportunity to play with the phone but it seemed to be working thus far. I have not had a chance to put a SIM card into it so I don't know if the new rom/Odin also flashed a new baseband and if the radio works.
will report back tonight,

S6 g920v - Locked out of my own phone and cant gain access. Radio off?

Ive read other posts and searched the web but I can't figure out what I'm doing wrong.
I have an old s6 I was about to sell so I downloaded the official 7.0 from samfirm and started installing via Odin. At a certain point in system.bin it freezes for 30 minutes. I pull the plug on it. I'm supposed to meet the guy in 2 hours at that point and I download multiple different vwz firmware for the s6 and eventually am able to boot up again. The problem now is that a stock firmware won't completely work (modem.bin) and the older versions from updato work except for system.bin.
So now I have access to my phone but when I go to login its samsung account locked. I try to type in my username and pass and it says "Invalid ID or password" and I even reset it but it still says invalid. I can see the phone on my "samsung wheres my device" website, but I cannot unlock it because it says radio is off.
Edit: Forgot to mention I tried to update from 6.0 to 7.0. Tried multiple 7.0 firmware and attempted to revert back to 6.0.1. I honestly don't know what firmware i'm on now.
It says im on FA50_g920vru4AOJ2.
I'm in the US.
So im wondering since i've frankensteined these firmwares together, is this radio issue because I've flashed a different vzw modem? When it's plugged into my PC it says device not supported. When do a factory reset I assumed it reset the modem back to factory as well.
I can post pictures if need be of the phone showing up in my samsung account so you don't think I'm doing something shady.

Stuck in a loop between custom binary blocked and downloading do not turn off

I turned off and then restarted the developer's mode in my S7 yesterday. When I went to turn it on today, I got the message "Custom binary blocked by FRP Lock. I used power / start / vol down holding all three and came to a screen that wanted to know if I wanted to download (probably Odin). I then pushed two buttons of which one was the start button (the one in the middle of the bottom) and the vol up button, which started the phone trying to download. It got the message Downloading "Do not turn off target". I figured out how to stop that, but when the phone rebooted, it was back to "Custom binary Blocked ..."
The information I need to download firmware (like the CSC), is either in my phone or not common enough to exist in the country lists with their respective phone companies. My phone is an S7 and probably a G930F, although I can't verify that because I can't get into the phone. I would not mind downloading Odin, but I understand that the information regarding CSC_home with regard to who my provider is and what country I'm in is necessary in order to install Odin and I don't know how to find that information or to find the complete model number for the phone.
Thank you for any advice you can give me. I would prefer not to have to use a factory reset on the phone to get it up and running again.
Changing OEM Lock does trigger FRP sometimes, like 2 years ago my friend had the same on his Note5, it wasn't that hard to solve.
You need to verify your device model (written in the download mode's top left corner), then download a recent firmware, flash it via Odin, after booting, it'll ask you about your Google account and in some cases, your Samsung account, too.
Unless you've forgotten them, you should be good.

Thanks very much. I got the info off the download screen.
Do you mean I should go ahead and download Odin and then hope to find the right firmware? That's giving me part of the problem. I downloaded two different versions of Odin
3_v3.11.1
3_v3.12.3
I think to get the right firmware, I would need to know the country 3-letter code, if the phone is dual sim or not and the service provider? Since my service provider is not among those listed (like telekom or O2), can I use "unbranded" for my country? Or is this information for the CSC entry something my provider could provide?
Also, if I enter that into CSC, will I still have the option for Home_CSC? I'm quite interested in trying to keep my data.
And finally, I don't think I set up any account which had to do with the cloud. If an account was needed to verify the operating system, then I hope to be able to figure out what that was.

It doesn't matter. Any firmware will get your phone booting, that's the point, if it was FRP cause you forgot the Google account, then perhaps you should be picky, but since you're not, then it's fine.
CSC gets activated when the phone detects your SIM card, that's how it knows where you are and that's how it sets CSC features provided for your region. If you pulled the SIM out, it won't apply CSC just yet. If you travelled to another country, your CSC will be changed (once you boot into recovery).
What model your phone has, so I can find you some files?

I'm making some progress. I learned you can get the model number off of the recovery screen which I got to with power / vol up / Home and by waiting for the Recovery screen to appear.
I then found a very close firmware in updato, but the last letter was a y instead of a c, so not the perfect model-number-match. That one with the wrong last letter was for my region in the EU. The actual matching firmware ends with a c and I found that firmware on multiple websites, but listed as being from Thailand.
Now, the strange thing is that I bought the phone in Germany for a trip to Thailand and got it unlocked before I went there. Since I'm in Germany and most likely Telekom, and since I've read to trust no website except Updato, which doesn't have the firmware for my exact model number, I've been wondering how to proceed?
You asked for my model numberOne of the non-Updato websites offers the firmware with a checksum with the file, but since updato doesn't have that firmware file, I couldn't know if the checksum was the right one.
So I think what you asked for was the model which is G930FXXU1DQHC
Thanks very much.

That's a very old firmware, it has U1, latest has U8, I had the same device, too.
A trusted, reliable site would be AFH, search for G930F and find large files, that's the firmware.
Hi,
I found the big file of 1.8 gb called G930FXXU1DQHC_DevBase_v4.3.zip and downloaded it and extracted it to a folder I created myself called odin. It's not what I was expecting. It is a whole lot of folders within folders within folders, but none of the files that I would expect to be able to click on for an installation by odin. I was actually expecting three files that were clickable, which I've seen in instructions that utilize Odin to flash the firmware.
The two main folders it produced were ALEXNDR and META-INF. There's a single file at the same level as these two folders called options.prop.
Edit, I will try to attach a screen shot of what I was expecting to get.
More Edit: I'm not finding an installation file, so I think I'm at the point where I need to install Odin, but I don't know whether I install it on my pc or on my phone and if I should install that before I install the firmware. That's the point, isn't it? That Odin is in place to install the firmware?
Also, I can't see any exe files in the zip file I extracted, so I don't know what could be installed.
What is it I should be looking for?
Thank you. You're helping me keep going.
I see you did not get what U1 and U8 means. For an example, this is the latest firmware for Galaxy S7.
But, you downloaded a U1 firmware, which is very old to be believed. Forget about that, download this one, extract it, and flash it via Odin.
Thank you for that information.
The short version: I'm back in! All the stuff below is my journey which was rocky. Had to do some more internet searches, which brought me to another thread here in the forum:
Can't flash firmware, RQT Closed.
Hi! I need help, I was trying to flash Indian firmware (latest) on my Note8 (N950FD) with french rom. But when tried to flash the rom with Odin, start the procces and less than a minute, finished and appears as success, but nothing happened...
forum.xda-developers.com
For others who come after me:
I downloaded the firmware files, started Odin, put the phone in download mode (power / vol down / home), then plugged the phone into the computer and clicked on the boxes one at a time in Odin and was directed to firmware files in Windows Explorer and clicked on the correct one. I wanted to save my data so in the box called Userdata, I entered the CSC_Home file. They were all accepted. Then I clicked on Start in Odin and after a short time, the scrolling of files on the left side ended. That's where the above link comes in which says to try using a more recent Odin, so I tried again with Odin 3.13.1 (with the Chinese figures).
This attempt went better, took longer and then my phone sat and blinked Samsung at me for a very long time. I finally turned Odin off with Exit and then waited some more while the phone was still plugged into the computer. Then it started installing what it had downloaded. At least by now the little Android robot wasn't keeling over anymore.
After that finished, it asked for my pin and accepted it and I got back to the home screen. It then asked if this was my phone number, which it was. And I could see! that it had a charge of 44%.
I then went into Settings and looked for the developers setting and found that OEM was indeed turned off and that probably caused the FRP lock to occur. I turned the developers setting off for now.
I was able to keep my data with one annoyance. Some of the less standard apps are giving me a pop-up when I open them that says the apps are always on, do I want to close them, and there's a feedback button which simply shuts the popup off. You have to keep turning this off. It seems to affect non-standard apps, so I may have to reinstall those. I'll look into that ... tomorrow.
Many many thanks! It was so great to find someone who knew how to help me! I really appreciate it.
