Hello Guys,
I need serious superuser help.
Trying to flash a custom ROM, screwed up my IMEI and baseband.
Now I get a null IMEI and a Baseband Unknown on the phone's info.
I reflashed to 6.0.1 stock using the methodology of this thread here:
http://forum.xda-developers.com/galaxy-s6/development/g920f-android-marshmallow-6-0-1-beta-t3293941
I also flashed a few different custom ROMs without any success.
I rooted and installed Wanam Xposed and IMEI Changer, (Using this link: http://forum.xda-developers.com/galaxy-s6/development/mod-wanamlite-1-0-t3095155) but even if the IMEI is showing right this time, the baseband still shows as "unknown" and the phone won't get any signal.
Before flashing the ROM for the first time, I kept a backup of the EFS. I restored it with TWRP but still no love....
I have read countless threads over google but I haven't manged to solve it.
Can someone help?
Did you back up EFS with TWRP? Some other tool?

Yes, TWRP I have the efs.emmc.win and md5 file.
I tried to restore with TWRP but still no love. .
Guys ,anyone? At this point I am really prepared to try anything
Last thing I tried is getting a full Nandroid backup from a fully working G920F and restored onto my own phone.
Still no love. Factory reset, wiped cache and data from TWRP but still no love.
What could be the issue then???
have you tried smart switch ??
It gives me an error when I am trying to setup the device initialisation:
"Unable to find the serial number,model name or IMEI on the Server. Please check and try again"
Have you tried using ODIN to install the latest stock image? That did the trick for my old S5 that had an IMEI issue. I highly recommend using the SamFirm tool from this site to download stock images directly from Samsung.

I used SamFirm and downloaded three different stock roms for the UK and one for the nordic countries. They all pass from Odin but the phone does not boot. I get
"DM-verity verification failed" and
Need to check DRK first" and the phone won't boot up ....
Is this error because I am trying to install a wrong CSC ROM ? Or an incompatible ROM ? I can't figure it out.
I believe the dm-verity error means you've got the wrong ROM. You need to download the firmware for the device/region your phone is.
I know how to fix it

The way of fixing DRK that I know is via box (Octoplus, Z3X, etc.), but often IMEI gets reseted in the process (at least it was in my case).
If DRK is damaged, phone won`t boot without a custom kernel (which trips knox on Android versions 5.1.1 and above), if DRK is fixed, phone can boot with stock kernel.
In SmartSwich I suppose you used IMEI from back of the phone without / right? And for model you used SM-G920F (or whatever model you have) in capital letters?

Stuck in a ****tier place than what I started.
Last thing I tried before my phone died was trying to install the latest Stock marshmallow ROM for my device. The one I downloaded via SamFirm passed Oding but never booted.
Since then, I have tried to flash 12 other ROMS with different CSCs (yes 12) from BTU (which my phone is supposed to be) to VIR , to O2U to TEN. Nothing worked!
I had kept a nandroid backup of a ROM that was working (5.1.1 without IMEI or baseband) and even that does not boot now either.
Stuck on Samsung logo

This sounds logical. Do you have a box? Where did you fix your DRK? And I don't think I really care about the IMEI at this stage, right?

Well, not necessarily I think... In one of my previous tries, I managed to install stock O2U_G920FXXU3COI9_G920FTEF2COH1 (but first I deleted the "hidden" partition from the tar). Was that a coincidence you think ? #not_sarcastic

That's right. Shouldn't I ? I can't reset the phone for the life of me!
Did you do a factory reset in recovery, immediately after flashing the correct stock ROM in Odin, and before booting into the ROM? Uncheck auto reboot in Odin, when flashing is done, power & vol- to turn phone off, then boot into recovery.
Sometimes it's the simplest things that help.

I did exactly what you described. Only issue is that as soon as the phone boots, it won't let me enter recovery immediately. Before entering, I see the Green/blueish Android screen trying to install something. It stops at about 33% and it says "erasing" and only then can I enter recovery. To which point, I can erase the cache and wipe data but the phone won't boot onto the System. It just hangs there.
Not erase cache & data, factory reset.

I can't boot into the system to factory reset because I am stuck in the Samsung boot loop. Wiping data and cache from recovery is the same thing... or is there something I am missing here?
Factory reset from recovery.
Have you tried booting into safe mode?

I'm going crazy. I wanted to upgrade my Samsung Galaxy S5 SM-G900F finally from 4.4.2 to 6.01. I rooted it years ago and never cared to upgrade through OTA, since it never worked. So I found out about the FlashFire app recently, and used it to flash a 6.0.1 firmware stock zip file I downloaded. Followed all instructions, left all deselected partitions as is, only flashed boot, recovery, system, cache and preload. FlashFire started working on it, reboots into loading logo screen for a while, I start getting concerned but then it loads up a screen showing "Optimizing files" of like 250. Once that got done, it rebooted. Here is where I'm stuck since then.
My phone has been soft bricked, it's stuck on an endless Samsung logo screen, that gently flashed back and forth, and there's a blue notification light on during this. So I googled what I can do, and I tried using Volume Up + Power Button + Home button, since that would get me into recovery mode. That works, but instead of the Samsung recovery mode I get the Clockwork mod recovery screen. I had completely forgotten that I even had that. But, the same options are there too, so I wipe cache, wipe user data, wipe dalvik and factory reset. Once I did that, I selected reboot.
And the same thing happens. Endless Samsung logo screen. Stuck on it for hours. Now I honestly don't know what to do. I've done the recovery mode options 3 times, nothing changes.
Someone please help me out, I can't figure out what went wrong and how I can fix it. I can't afford a new phone...Ideally, I would like to be able to completely reset the phone entirely to factory settings. Is this possible? I appreciate any advice I can get.
Download odin and flash the whole firmware tar.md5.
4.4.2 to 6.0.1 is a big step so you'll probably need all partitions in that file.

Thanks for replying. Which firmware? I don't understand what you mean by all partitions. Will this Odin method really fix my bootlooped phone?

For some reason the recovery flash diden't work, and custom recoveries can't extract the csc-zip that its inside cache.img.
It could be that bootloader, modem and other partitions needs to be updated as well.
Yes. I think you'll need to flash the whole firmware with odin.

When I googled how to properly use FlashFire when I first used it (which then lead to this soft brick) I read that you shouldn't flash the modem and other priority partitions that were unselected. So now I should do it?
Where is the best place to get firmware? And which firmware do I even get? 6.0.1? Or my old 4.4.2 to get it back to it's original state?
Help pls

Either 4.4.2, 5.0 or 6.0.1 would do since you only flashed four partitions.
Use http://updato.com/firmware-archive-select-model?r=&v=&q=SM-G900F&exact=1&rpp=15
You can sort it by version, date, region etc.

Ok. So you're saying I download let's say the 6.0.1 from there, then I download Odin, connect my phone in download made and flash ALL partitions from that firmware? This will get my phone out of this crazy bootloop Samsung logo soft brick it's been in for 3 days?

You make it sound like odin is some shady, untrusted software while it's in fact the very same software that samsung service centers use, flashing the very same firmware packages. I'd say it's far more reliable than any app you can flash with.
They're only good for smaller partitions like boot, recovery but not for upgrading android versions.
I can't guarantie anything, but yeah, going from 4.4.2 to 6.0.1 I'd say you'll probably need updated bootloader, modem etc to make it work. Flashing whole .tar.md5 package will fix that.
Unless you have some better idea...
And don't be mad at me if it turns out it's not working.
You're the one who messed it up in the first place. I'm just trying to help.

thank you a lot but i have another question after i ran a boot.tar from firmware.obi my phone is stuck on the boot logo what can i do to move on and is it safe if i boot the files u sent me with the current state of my phone? also the download will be ages since the speed for non premium is 15kb/sec
To return the phone to a stock condition, you flash the ROM using Odin which will overwrite everything with the possible exception of the data partition.
If the phone is stuck at the boot logo, have you tried a factory reset from stock recovery?
You can try this link: http://samsung-updates.com/device/?id=SM-G930W8 or https://updato.com/firmware-archive-select-model?exact=1&q=SM-G930W8
I don't know about download speeds for the above-two links as I have never used them before but other XDA members have.

After downloading the file from sammobile.com, unzip the file once (I use 7zip) to yield the necessary files. Each file will be preceded by the blank or slot location.

so i managed to get this phone back to its original state when it was frp locked by downloading software from sammobile but it still remembers the google account... i will try to download a older version of android and run that to hopefully get the phone to 6.0.1 or whatever the original version was and try some older ways to frp unlock my phone because the older version will have less security patches. hopefully this works! thanks for the help so far .:good:
I'm not sure that you can downgrade once the phone has been updated.
Good luck.
same here, stuck without solutions. tried pretty much everything found on the internet carefully and taking the time to do it.. but still...
i still need help can someone find a way to unlock my phone?
One way to remove frp lock is to flash a custom recovery (like TWRP) for your phone and then use the wipe -> format data (and type 'yes' when asked, without the quotes). Restart the phone and let the system boot. After it boots you can procede to flash the stock rom
* P.S. 1: flashing a custom recovery will trigger KNOX so say bye bye to S Health if you are not planning to root the phone (so as to be able to edit the build prop and enable SHealth again) after flashing the stock rom again. Do not attemp to flash the stock recovery image on its own or your phone will be soft bricked and the dm-verity error will give you nightmares (happened twice to me, took me 6 hours to recover my phone). To get back the stock recovery you need to flash the stock rom again.
* P.S. 2: If your phone has the bootloader locked you will not be able to flash a custom recovery. In that case you can try to downgrade to 6.0 but there are not guarantees that it will work ok.

hi could you please link the stuff i need to download in order to to this my phone is SM-G930W8
Hi,
Using latest Odin I am trying to return to my phone to stock but cannot
I have tried 4 different firmware’s already (over 20 times) and each one will PASS the flash process, phone rests, installing system update (stops at around 30%) and during the blue screen the update stops, resets, receive Erasing message for a bit and then NO COMMAND and phone will simply not boot. (with some flashes the stock recovery is not even available, working or present)
... only way to boot the phone is to install TWRP... installing the NO VERITY file seems to help in booting…
I have noticed when i plug the phone is it comes up as another device name (from a previous ROM) so i am guessing it hasn't been wiped correctly (i did formats, factory resets, wipes many many times and no change)
Back in DOWLOAD MODE under system status = CUSTOM (after flashing stock firmware)
My guess is that the new firmware I flash simply wont stick, or is half installed, or could be something to do with encryptions,
Some of the logs I see include:
Failed to open recovery
Reboot recovery cause UNKNOWN
E: Failed setting up dirty target
Fail to mount /system as rw
i have no idea what else to try

You flashed the wrong firmware and corrupted your device.
You should flash the newest available firmware for your specific model number. You might have to flash the PIT file for your model number along with the firmware with the "re-partition" option checked in Odin when you flash it.

If you didn't flash the firmware then how did it show up as a different device "from a previous ROM", as you said?
They might have been V3 firmware, but was it for the same model number of V3 as yours? Are the model numbers different? Is V3 the model number? Or is it the device branded name?

Have you tried factory resetting the device then try flashing via Odin? Sometimes there is conflicting data that prevents from flashing the firmware.
You might not have a choice of which firmware to flash to repair your device.

Well then, suck it up and flash the newest firmware, you are out of options.
Your device probably doesn't allow downgrading, in this case, you can only flash exactly what was on the device before you caused the issue or a newer firmware, you can't go backwards to an older firmware.
If you're trying to flash an older firmware in an effort to get past a locked bootloader, you are probably wasting your time, that doesn't work out most of the time.

That definitely makes sense that i cannot downgrade but i am flashing either the same firmware or slightly newer staying on the same bootloader version.
I have a situation now. When I first got this phone, it was stuck in a firmware that is not from TMK/TMB. Here is what I have vs what it's intended because I don't get any updates since I am stuck on the April 2021 update. It had a Metro By T-Mobile SIM inserted which converted the CSC to TMK (I forgot the original one, but according to the Phone Info app its XAA but the triple code says TMK/TMK/VZW.
Intended TMK/TMB firmware:
G975USQU5GUCG (March 2021 update)
What I got
G975USQU5GUCH (which is Verizon/USC/Comcast/Xfinity only)
However the update for the May 2021 patch is the same:
G975USQU5GUE2
I tried flashing the TMK update but it instantly failed the moment it started (thankfully it didn't break my phone). However, how am I supposed to get the right firmware for the CSC? Thank You...

It had a Metro By T-Mobile SIM inserted which converted the CSC to TMK (I forgot the original one, but according to the Phone Info app its XAA but the triple code says TMK/TMK/VZW.
Intended TMK/TMB firmware:
G975USQU5GUCG (March 2021 update)
What I got
G975USQU5GUCH (which is Verizon/USC/Comcast/Xfinity only)
However the update for the May 2021 patch is the same:
G975USQU5GUE2
I tried flashing the TMK update but it instantly failed the moment it started (thankfully it didn't break my phone). However, how am I supposed to get the right firmware for the CSC? Thank You...

Flashing the March update should have worked with no issues. When you flashed it, what method did you use to flash it and did it give an error when it failed? If so, what error did it give?

I suppose the SD card update, I tried it and it said something about 6 bytes not detected before aborting it

I used the update via sd card mode which instantly failed with some byte failure. The file was for TMK. Seems odd, I think it's the current firmware prevent that one from being downloaded

Try downloading the full firmware update then flash it via Odin.
Google search for:
"Update for (your model number)"
Find the firmware update(not the OTA update) that you want to flash and download it to a PC, it should be a .tar.md5 file, not an update.zip. You may have to extract the downloaded file using 7zip to extract the .tar.md5 file.
Then do a Google search for:
"USB drivers for Samsung phones"
Download and install those drivers on PC.
Then do a Google search for:
"Odin for Samsung phones"
Download and install Odin on PC.
Do a Google search for:
"How to flash firmware via Odin"
That should find a guide to follow to flash the firmware.

Does that require a hard reset? Or does home csc can be used?

It shouldn't require a reset, but, to be safe, you can back everything up to Google as if you were tranfering data to a new device then restore the backup the same way you would when switching to a new device.
You should also backup your photos, videos, downloaded files, user installed apps, user app data, and any other user data that you want to save and store that data on your PC or backup user data by whatever other method you are comfortable wirh, do a Google search for backup methods if you need to.
Then flash the firmware using the Home CSC. It shouldn't wipe your data but if it fails to flash try flashing the firmware with the non Home CSC.
If it flashes successfully with the Home CSC and boots successfully, it shouldn't wipe your data so you shouldn't need to restore anything but if it acts buggy you will probably need to factory reset it and restore your data from Google and/or PC or whatever method you used to backup/restore user data. If it flashes successfully with the Home CSC but then bootloops after flashing and booting the new firmware, just boot into stock recovery and factory reset the device and wipe the cache partition then reboot the device and see if fixes the bootloop. If it boots successfully this time, restore your data from Google and/or PC or whatever method you used to backup/restore user data. If it still bootloops after wiping in recovery, try flashing the firmware with the non Home CSC, if it successfully boots after that, restore your data from Google and or PC or whatever method you used to backup/restore user data.
