get a fresh DL of your firmware from a reputable source and reflash it in Odin, if that doesnt work, get a fresh DL of Odin. I use sammobile.com/firmwares for my FW's and i use samfirm to download them as they literally go 4 to 5x faster on Frija or SamFirm. Frija and SamFirm are damn near the exact same thing, so its a eenie meenie miney moe thing there. But for sure use one or the other unless you dont care about a 20 min disparity LoL
if the flash with fresh FW and fresh Odin downloads dont work, try a different cable. Then a different computer. I have 7 computers and for whatever reason, one of my lappys just wont link with the target devices very well... not sure why... im sure i just havent made the proper sacrifices to the USB gods on that particular machine. purported deities aside, literally all of whose things could be the culprit... well.... minus the USB gods one, of course

Hi, I'm new here, basically I made this account just to get help. I have the same issue, I bought my S8+ back in 2018 and never received OTA updates automatically, it's still in Nougat. Recently I decided to update the OS to Android 9 based off of Sammobile, the model number is SM-G955FD, in the Service Provider SW ver. it shows SM-G955F only(is this an issue?). I dowloaded the latest firmware for SM-G955FD with csc XTC. Now there is the other thing where the volume up button isn't working due to water getting inside, it still works. The key combination can only get me to recovery mode same with ADB, when I try to reboot to bootloader(OEM unlocked) my phone just restarts, same with ADB reboot bootloader, when I do ADB fastboot it gives a blank response. That being said I can't proceed to flash with Odin, I'm thinking of using ADB sideload but I don't know where to find the zip file or whether it's the same one I downloaded from Sammobile(pretty sure it's not).

in cases such as yours with micro usb equipped samsungs in the past, there was a jig that you could plug in and it would automatically put t he phone into download mode. All the jig did was provide 300k ohms of resistance between 2 of the jumpers inside the micro usb port. I wasnt able to find a type c jig, but there are type c test boards that basically expose every pin in the cable into a nice wide board thatll allow for easy connection between 2 of the jumpers by hand to test it out. I did read somewhere that the newer ones require 301k ohms, but its hard to say. The usb port board is 13 bucks and a resistor is gonna be less than a buck. Maybe worth a shot since the micro usb jigs were gold

also, the only difference between the F and FD firmwares is the D is for dual sim

ich have same problem

[Q] Bricked Qualcomm's secondary bootloader, what to do?

Hello everybody,
I got my hands on this phone and I tampered too much with Qualcomm's FAT partition with the secondary bootloader, hardbricking the phone itself.
Trying to turn the phone on, shows the Samsung logo for some seconds then shuts down and disconnects, Download Mode is unaccessible but with VolUP+Home+Power the phone just stays connected (with the screen being black), but ignores any attempt to flash, Odin staying stuck on "SetupConnection...".
What I've tried already:
- Flashing with Heimdall -- phone isn't even recognized
- Removing the battery "trick" etc, etc, etc
- Changing .tar.md5 package
- Forcing a repartition with the .pit
Any clue might be useful, thanks in advance to anyone replying.

You shouldnt had to play with the bootloader neither the SBL
Im sorry to tell you that if your phone doesnt acces neither recovery and download mode it is hard bricked
that is why odin doesnt recognize the device
however, USB JIG is the best solution (the other one is changing the motherboard)
You can follow this instructions http://forum.xda-developers.com/galaxy-s2/help/guide-how-to-make-usb-jig-reset-binary-t1604707 to build one
using this SHOULD work but its even possible your bootloader is so messed up that will not open
You told me there about download mode, what about recovery mode? althought it should not work maybe God gives you a second chance

Actually ODIN recognizes the phone, but hangs on "SetupConnection...", sure the simplest solution might be the jig if there's a secondary bootloader in situ.
Obviously the recovery mode is dead, but still, I saw that it bypasses Samsung's logo and just reboots.
Since it's Qualcomm, probably the microSD emergency procedure used on the S3s might be a fair try.
If someone has still a working phone, can please do a dd image of the first 100 MB of the EMMC so I can see if this option is viable?
Might be a nice solution for hard bricked Qualcomm-based Samsung phones to unbrick those.

First, for the SetupConnection try changing the ports but first BE SURE Kies is closed or end the task as Kies closes your connections using third-party programs
then reinstall samsung usb drivers or even adb drivers are good.
if you will find anyway to execute the command adb reboot-bootloader you could probably save the phone
2. I just read about the microSD procedure, it looks like a pretty clever idea
I wonder how do you know how many MB's you need
so i have done here a 70MB IMG, and with 100 didnt worked so I did a 99 MB one
Remember you need Class10 16 GB Card
If somehow this solved your problem, i will do a post in our General Section
Good Luck, i'll stay tuned.
EDIT: I just noticed the files have 169 MB so I can't post them here, tell me your email and i send you, my email is [email protected]

I don't have Kies installed, since I never kept any Samsung phone with the stock TouchWiz ROM, but only the USB Drivers package for ODIN and so on.
I sent you a PM with my e-mail address, but you could upload the img to MEGA or whatever file locker service...
In the case this get sorted, I'll upload the IMG over my server and drop the link, so you don't need to worry about the link expiring or whatever

Tried to burn the SD card, it seems that the 7227A doesn't support boot-from-SD.
Anyways, I ordered off eBay for some change a jig dongle, as soon as I get that I'll try that way, but I think that it won't work since most of the hardware components (except for the NAND) are not made by Samsung.
I'll let you know how it proceeds

[Q] please help, softbricked galaxy s5 active

i made a extremely poor decision and was trying to change the boot animation loader when i actually changed the boot cmd and now it boots to samsung then to download everytime,. i can get into the onboard recovery yet i cant access safestrap and none of the many many drivers ive tried i cant get the phone to show to connect, its listed as unknown device in my device manager and ive hand picked the ones im supposed to have to other ones. ADB doesnt see it either and i was wondering if there is cmd for adb to find myu device, if you help me guys i promise ill only practice on hand me down smart phones. Ty:cyclops: [email protected] SM-G870A
This may be a dumb question, but have you tried Odin? I have had situations similar to this with my Samsung devices and always thought i bricked. But as long i could get into download mode, i could Odin back to stock and start over.

ya but i havent even tried loading a file into odin cause it wont see my device
and i have installed the samsung drivers but after this happened my pc wont see the phone
has to be a way to get a connection between the pc and phone
I'm not an expert so I'm not sure. Do you have the correct drivers installed on PC?
---------- Post added at 06:34 AM ---------- Previous post was at 06:30 AM ----------
Try different Odin versions. And make sure you have the proper drivers installed on the PC.
ya ive actually read that it probably doesnt have the function running to talk with the pc cause it cant boot. im all set up to reset the phoone. just need it to appear in my odin

When you boot to system
It doesn't show anything right ??
but the touch is still functioning
Sent from my GT-i9300 running cm11 using tapatalk.
when i just boot it goes to download mode and says "could not do do normal boot"
i can access recovery mode and download mode but i cant get drivers to show it, and it used to show it until i did this, can i put a file on my micro SDcard from my pc via card reader then install it in recovery mode ? like firmware or a memory wipe reset?
If you can get into recovery, I believe that would be possible. Couldn't hurt to try. As long as you can get into recovery and all the recovery functions work, I don't see why you couldn't.
fixed it!
well after two nights of reading i got my pc to discover the device by changing ports three different times to find one that seamed to like it. and also installed kies and installed the drivers from them, (figured couldnt go wrong after as many as ive used from samsung and others). so win7 pro / altered boot command and only stock options afterwards sucks big time. ty all for helping me
never let up

Need help with Unrooting Galaxy S7 SM-G930A

My phone is a Samsung Galaxy S7 SM-G930A. I recently rooted my phone and it was causing alot of problems such as slowdown and bugs. So, I tried to put stock firmware on it and I was unsuccessful. Now my phone is stuck in a boot loop. I need to know how to properly install stock firmware into my phone because I have followed guides on XDA'S website and Odin keeps failing. I really need help with this because I don't even have a working cell phone.

Thank you for the response but when I connected my phone to Kies 3, I got a message that said "we do not support this device". I have also tried Samsung Smart Switch and that did not work either. Is there another method for restoring my phone and getting it out of the bootloop?

Yes i know you get that msg in kies but you still will be able to flash the orig fw back to the device with kies. Just put the phone in download mode before hooking up the phone to the pc then start kies
And go to the top bar and select the 4th tab where you will see recovery. Then it will ask you for the model number and some other things and after that it will flash the fw for you. I have done this a couple of times now so i can tell you 100% that it will work

I'm actually trying to do exactly this now, and have tried re-entering the correct model number and serial number into Kies numerous times.
No matter what, Kies continues to state "Please check the model name and enter it" even though all of the info entered is correct.
Any suggestions? I'm doing this with my G930A on Nougat (model "SM-G930A")

I think my s7 edge SM-G935F its now just a brick...

I wanted to update my s7 edge to oreo via odin. So, i think i just flash it bad (instead of put one archive in bl i put other in ap, idk things like that). so i saw it told me An error has occurred while updating the device
software. Use the emergency recovery function in Smart Switch. I tried flashing again the firmware in odin but it just stuck in initialization. I just tried in diferent version of odin nor switch mode.
I tried with diferent usb cable nor other usb port
When i try to recover it with switch mode it just tell that it cant because it isn´t compatible (I even put the s/n)
Could someone tell a alternative tool to odin?
Help please, i think im losing my s7
I'm not an expert, you could try using Heimdall (https://glassechidna.com.au/heimdall/) instead of Odin, not sure if that helps.
If not then your phone may be bricked.
If you are desperate there is this thing called unbrickable mod that requires physical intervention, but I haven't found it for s7 edge

[Need Help] Very bad case of soft brick S9+

Hello everyone,
so my phone is soft-bricked after failure attempt to flash combination files in order to fix the csc.
I follow this thread, but the problem actually has nothing with that.
I used the latest patched odin V3.13.1, with a combination file named COMBINATION_FAC_FA80_G965USQU3ARG2.tar, and the proccess failed at flashing the system, and now i'm stuck; unable to flash other firmwares.
Before that, the phone was working perfectly after I've flashed a G965U1 firmware on it, in order to get rid of the bloatware of the original branded G965U (I don't live in the US).
Also, it successfully OTA updated to the latest G965U1UEU3ARK5 Firmware just a few days ago.
Things that I've tried so far with no success:
*Used different usb ports, both usb 2 and usb 3; and different cables
*Using both an Intel-based PC, and an AMD-based. (I know it may sound unrelated, but thats actually what prevented me from flashing the G965U1 fmwr the first time I tried, because i was using and AMD PC)
*Reinstalling Drives, installing latest kies, installing latest samsung smart switch
*using older versions of Odin
*tried to install the original Sprint firmware (v2) G965USQS2ARF4 through odin
*tried to install the G965U1UEU3ARK5 firmware through odin
The phone is stuck in download mode. sometimes if I disconnect and reconnect it, I get an unrecognized usb device message. so I need to reboot the phone again to download mode so the pc will recognize it.
and the result is always a failure:
either due to rev check, with the original OEM firmware
during the installation at 'vendor'/'system' step, due to auth error, when trying the G965USQU3ARG2 Combination file or the G965U1UEU3ARK5 files with patched odin
or even before that step with older versions of odin.
I'm out of ideas... I hope someone here has the knowledge to help in some way, Please...

Guys at imeigurus has a service. Check on them. Those guys have access to special Samsung firmware that they can manipulate Samsung's as they like. They do what others can't, they can support you remotely using teamviewer. But snap the download pic here let me see

after writing this post I realized that I haven't tried flashing an OEM rev3 firmware
so I downloaded one after finding out which one is the right file
and I tried flashing it on a completly other pc than the 2 I've already tried it on
and it worked:victory:
here's the recovery after the successful flash:
