Galaxy S7: Can I flash Firmware purely from SD card? - Samsung Galaxy S7 Questions and Answers

Hi, new to the forums.
My S7 is playing up (due to toddler getting hold of it and doing who knows what), it just cycles when attempt to boot. Can get to Recovery screen okay. Safe mode not working. I've resigned myself to buying new phone, but, there's some files/photos that I'd like off it.The charging/data port appears damaged, as it won't accept charge, nor recognised by laptop. Wireless charge works fine.
So, I'm wanting to flash the Firmware to see if helps, but, I can't connect via USB. I have the Firmware .zip file on my laptop (that would normally be used via Odin), and a micro-SD adapter. My question is, can I flash the Firmware via the SD card/recovery menu? I've done stacks of googling and got ambiguous answers.
Any help would be appreciated.
Thanks

You cannot flash official Samsung firmware from an SD card; you must use Odin. You CAN flash custom firmware from an SD card, provided you have TWRP installed. The one you should use is https://forum.xda-developers.com/galaxy-s7/development/rom-dqd2-devbase-v4-1-multi-csc-safe-t3592914 , which is, for the most part, equivalent to stock.

Either way from what you've said your options are very limited.

Thanks for that. I assume TWRP is an App that I would have to install and then access on my phone? I'm unable to, as the phone won't boot normally or in Safe mode; all I can do is get to the Recovery Screen. Is there any other possible workaround with that in mind?
Thanks again.

TWRP is not an app; it is a "recovery" substitute, and it must be flashed from Odin. I thought you might have had it installed already.

[Q][NS4G] Problem with fastboot and fixing phone.

Hello, I recently decided to root my phone and place Cyanogenmod on it. When I did that I realized my radio was no longer working. In an attempt to just get back to a working phone for the time being I flashed a rom that I believe was just for the Nexus S and not Nexus S 4G. Due to my stupidity I am unable to communicate from the device to my computer using USB. When I attach the device to the computer nothing happens. The device does not even appear in the device manager. I have tried on multiple computers as well. On top of that the rom seems to have put me back into the stock recovery. If anyone could help me figure out just how to get USB working again I would be very appreciative.
I should note that I can still transfer files to the phone using the sd card or via ftp.
Thank you for your time and help.
Change the USB cable?
Yes, forgot to mention that. I have tried 2 cables both of which work on other devices.
What if you hold in the middle of the volume buttons (i.e. both up and down at the same time) and keep holding, then plug in to your usb port? It should come up as download mode. If it will do that you might try using Odin.
Or try a different machine perhaps?
are the drivers the same for the S as the 4g?
do you have clockwork on the phone or have you tried to run recover by holding volume up and power?
just throwing things out.
Hello, I appreciate any and all suggestions and help.
I have Odin downloaded and installed, but the computer can not find the device so Odin can not do what it needs to do. This is even the case in download mode.
In terms of recovery I am on the stock recovery. I was on clockwork but made a small mistake and now am back to stock.
I know if I can just get the computer to see the phone exists I can fix it.
If you can find the full OTA package for NS4G, you can try putting it on the SD card and flash it via stock recovery.
Also another thing worth trying is connecting the phone to an Ubuntu machine and see if it's detected or not.
I have tried looking for the original full OS. I will continue looking, but the different OS thing is a good idea I did not think of. I will attempt that now. Thank you.
I installed Ubuntu and the Android SDK and Ubuntu was unable to see the phone as well. I am going to keep searching for the original firmware to see if that will fix it. Thank you for your help so far, it is greatly appreciated.
I have found the only rom my phone will accept now is
Android 2.3.4/GRJ22/KRKC1 Radio/KA3 Bootloader
Which is for the M200 variant. This apparently the Korean version.

[Q] Restore stock firmware via SD card

I have a Samsung Galaxy S 4G (SGH-T959V) with kernel 2.6.35.7-T959VUVKJ6-CL694130. I took this phone to a place to get it unlocked, but now it does not recognize any SIM card nor can I connect it to my pc or laptop via USB. I have been looking all over for ways to restore the firmware, but I can only find ways that require download mode and a fully functional USB connection. I downloaded and installed the Samsung USB drivers, but I can only get the message that the phone is malfunctioning and remains undetected to Odin and Heimdall.
I am not able to find a reference on how to flash my phone from the SD card and I am not sure which files I need to put onto the SD card to even attempt it. Could someone please help and include links to stock firmware files?

Well, it sounds as if you have two separate issues.
1) No SIM cards are recognized. Do you know if you have an IMEI number still? You can find it by either typing in *#06# in the dialer or by going to Settings, About Phone, and Status. If you have a string of numbers, then you're probably good. If its all 0's or *'s, then your efs partition is probably messed up. In which case things get complicated (especially if you don't have a backup of the efs partition) and just restoring the stock firmware probably won't help.
2) You cannot get your PC to recognize the phone. I assume this means that you cannot transfer any files to it either (ie Mass Storage Device does not work) as well as Odin/Heimdall not recognizing it. I'm assuming you can get into Download Mode?
The first things to try would be a different USB port and/or cable and/or PC. Is there anything showing up in Device Manager? Another thing to try would be to download a LiveCD of a Linux distribution such as Ubuntu or Linux Mint. If it gets recognized there (type in the command "lsusb" at a command line/terminal) then its a problem with the Windows drivers. Don't try this right away unless you have a good internet connection as its a fairly hefty download.
In order to get back to stock from the SD card and without download mode, you will need a custom recovery. While you gave your kernel version, a little more info would be helpful. Are you currently on the stock rom? If yes, do you have a custom recovery or custom kernel installed and are you rooted? If not, which ROM are you using?
Welcome to the forums!
Thanks for the reply. I know this will probably scar me for life, but I just figured out I was putting the SIM card in wrong. Now the USB works great.

Samsung Note 1 - USB not working

Hello!
I have Note 1 N7000, about 2 and a half years old and I'd like to keep using it.
It has it's original OS 4.1.2, factory reset has been performed about 2-3 times.
None of the USB functions work - data transfer, tethering, OTG, nothing. I can only charge the phone (but not with any cable which indicates a bad [worn out] USB port).
The problem came out of nowhere (as it always does) - one day I wanted to transfer files via cable and the phone simply couldn't be recognized by the PC.
Before that I disabled some google's apps (and some others) that I never used so I performed a factory reset just to make sure I didn't disable somenthing required by usb to operate but with no luck.
I ordered a new USB port (the little board with usb) from ebay and installed it today by following instructions from youtube.
The phone can now be charged with any cable (as expected) but all other USB functions still refuse to work (not as expected).
I'm currently out of ideas, what could be the cause?

i would re-flash stock. you should be able to find a guide and files in your devices forum.
you could have some corrupt files, and a factory reset wouldnt fix that.
if stock doesnt fix the problem, you likely would have some additional hardware issue, im not sure what it would be though.
short story: I installed custom ROM (this one: http://forum.xda-developers.com/showthread.php?t=2179332 - the v16) and it still doesn't work.
Long story:
Stock recovery didn't let me to create a backup, nor it allowed me to install ROM from SD card. I couldn't flash via Odin or some other similar tool because my phone's USB doesn't work
I figured out I should try a custom recovery.
Is there any other way to flash a stock ROM (or any other) than installing it from a SD card? I haven't done this before so please, be patient
I found PhilZ Kernel (5.0.3) and CWM recovery (6.something), merged into a single .zip that could be put on a SD card and installed from there. It said it was for XXLT5 (which is my version of 4.1.2) if that matters.
Installed it and now I had that CWM recovery that gave me the ability to create backup and flash from SD card.
I downloaded stock ROM from SamMobile.com, identical to my original one (XXLT5, my country, my operator, TWO mark), put it on SD card, did a full wipe and tried to install it but it said "installation aborted".
Then I downloaded another stock from the same site, also XXLT5 and Croatia but no carrier specified, TRA mark. It was the same size (786 MB) as the previous one if it's of any importance.
That one also refused to install.
Then I searched for a custom ROM until something not too wild shown up, the link is in the beginning of this post.
It installed normally from SD card and it behaves normally too, except for the fact that the USB problem persists.

you cant flash stock firmware through recovery.
take a look at this. it flashes stock firmware from on the device.
you will need to verify there is a version for your device, and how to use it. i have never used it myself. seems simple enough though. put firmware on device, flash with app. done.
Thank you for this, excellent app.
I flashed stock ROM successfully, but USB still doesn't show any signs of life (the only thing it does is charge battery).
...not a very bright future, right?

right, now that you are clean stock, there should be no reason its not working other than hardware.
edit, maybe try some different usb cables, could be you got a bad one.
I have several other cables and other phones (and other PC-s) at home. All combinations work on every PC.
It's only my phone that doesn't work regardless of which cable I use (or which PC I try to connect it to).
One friend suggested me to downgrade it to 2.3.5 (and then try to update it back to 4.1.2 in case it works [or even if it doesn't ]). His idea is that it might work because gingerbread uses USB mass storage protocol instead of MTP.
I downloaded some apps (tried a few of them) which switch from MTP to USB mass storage (in 4.1.2 ), one even required reboot after changing the setting but none of them gave any results.
Somehow I doubt this switching back to 2.3.5 would work, should I even bother?

[Completed] Help! Seriously messed up ROM mod on Galaxy Tab 10.1

So I got this free Galaxy Tab 10.1, and tried adding a Custom ROM to help it run better, and be able to run some apps that the old android 3 os couldn't run. As of now, it has CWM v6.0.3.6 installed, as well as a KitKat ROM. This ROM seems to have been corrupted, and now the keyboard constantly stops working (receiving constant pop ups about it) and it no longer will connect to my PC via USB, although it still charges when it is plugged in.
I made a mistake when I was installing this ROM, and my backup stock ROM was never loaded onto the tablet.
My original thought was to use the install from sideload option to get a different ROM onto it, but it doesn't detect even in Recovery mode.
Odin does detect the device, so is there a way to use this utility to fix this problem? Or maybe some other option that I'm not thinking of?
Thanks for the help

Greetings and welcome o assist. If odin detects your device then kies emergency firmware recovery should work, that will return your tablet to its original state. The other option is to flash a different rom through recovery, just download it to your sd card and then flash it
Good Luck

I booted the device into download mode, where it is detected by Odin. Kies can tell that something is connected, but it just continuously tries to connect. The device does not have an sd card slot, so there is no way for me to add a different rom to it.
EDIT: Kies does not detect anything being connected at all if the device is booted normally.

Additional update:
By using the calculator app to copy paste numbers, I've gotten the device connected to my phone's hotspot, along with my laptop. Perhaps there is some way to force a file download over wifi? The device shows up in my network places on my laptop, but the folder is empty.

If you start kies and select emergency firmware recovery it will ask you to put your phone in download mode and connect it. Does kies recognise it then?

Problem resolved, I was able to locate a Samsung release 4.0.4 for my device in .md5 format and flashed it with Odin. Thanks for the help.

[Completed] Samsung Galaxy Alpha without operating system

Hello XDA,
I'm using a Samsung Galaxy Alpha and I've recently wiped the whole phone due to the custom ROM draining my battery. Now I have a huge issue. I do not have an operating system on my device and I have no idea how to get one. I've tried to flash the original firmware via ODIN, but it won't boot up. I can't transfer a firmware to my phone via sd card and install with TWRP Recovery since my phone does not support SD card. What can I do? Can I transfer files to TWRP via a USB stick that plugs into the phone or transfer files via USB cable to my computer?
I will be happy to provide more information if needed.
Thanks,
Vegar
