G935T won't boot past the Tmobile logo - T-Mobile Samsung Galaxy S7 Edge Questions & Answer

So let me start from the beginning.
1. Got a phone as a gift from my uncle. A G935T but had a cracked screen.
2. I accidentally factory reset it with the recovery menu and not the one at settings, leaving it FRP locked.
3. Take it to a shop and replace the screen with a G935F one and also get it FRP unlocked.
Everything good so far and it boots up perfectly. However whatever card I insert it will not detect its network but it knows that a sim is there and it just shows a stop sign instead of the signal bars.
After some research I find that when I dial *#0011#, it showed something that said "MIPI device fail". Googled it and it said that it was hardware failure. So I thought that when the guy changed the display he kept the G935F antennas and not the ones that came originally. So I give him the phone and he replaces the parts and for some reason he decides to flash the phone again and now the phone won't get past the TMobile screen after flashing, nor can the recovery be opened. I currently have my phone, however in pieces as he didn't assemble it and I forgot some parts at the shop. I have my phone minus the back cover, vibration motor and maybe something else is missing idk. But he changed the phone back to the old display and the old antenna and nothing still. I tried countless roms, tmobile and the USA unlocked rom. Still nothing. Repartitioned the phone using a pit file and odin and still nothing.
When I try to open the recovery it says "Installing system update" and it won't get past that.
How do I fix this?

Another, "Is my phone bricked?" THREAD!!

I was rooting my phone last night and was successful. When trying to load a Cayanogen rom, it wouldn't get past the "Vodafone" splash screen. I noticed I did not have the proper radio installed, so, I installed the radio for Android 1.5 from the website.
Now, it is stuck in the red vodafone splash screen, and won't let me enter fastboot, bootloader, or recovery.
So, am I screwed, or is there a way I can fix this? I honestly searched for a VERY long time, and could not come up with much help.
Thanks. Also, I am using this on AT&T and it is unlocked.
if you can enter fastboot or recovery or anything than its not looking good, have you taken the battery out for a while and tried fastboot again?
I'll try leaving the battery out for a little while and try again. I just let it sit on the splash screen for about 15 minutes with no luck.
Left the battery out for 20 minutes, put it back in, tried to enter bootloader/fastboot/recovery, still with no luck.
Any other suggestions? I literally just bought this phone last week!
Also, since I am on at&t and this is a T-Mobile phone, and it is bricked, is there any way I would be able to send it in for a warranty replacement? I have no receipt of the original purchase, but still have the original packaging.

Black screen of death after flashing firmware

I have the S7 Edge originally the ATT version but I rooted and flashed the unlocked version firmware. I was trying to unroot the device and restore everything to the factory settings since I am using the trade in program through Samsung and have to send it back in stock. I tried to flash it using Zodin, the Mac version of Odin, but was unable to get it to work because I was not able to get the proper pit file, it always returned with the error that there is a corrupt file. Since I do not have Windows, I could not Flash the firmware using Odin. Out of desperation, I looked online and a website (the article was on Android forums with the title restore stock with flashfire no PC) said that I could use the Android app Flashfire to flash a firmware and return to the factory unrooted settings. I downloaded and inputted the full firmware file for the original AT&T firmware version and checked the boxes to wipe boot, system, internal data, and trusted Zone and also maintain everroot. It seemed to work and was processing with the fast scrolling command text on the black screen but after a few minutes it said there was an error at the very bottom of the screen. Eventually, it restarted but nothing has come up and the screen is black without any light from the LED indicator. I tried to restart it with the power button several times, holding down the power button and the volume down, holding down the home button and the power button, and holding down the power button, volume down, and home button. I left the phone unplugged overnight and plugged it in this morning to see if it would turn on but nothing happens. Any help would be greatly appreciated and I am hoping that I did not brick the phone.
Since Im not sure now if you also tryed to go in download mode again but ussualy you are always able to do that.
If not try to remove battery and put it back in after 10 minuts. And connect it to your laptop and let it charge for a few minuts. Next Hold buttons for dowload mode. Hold em for 5 secconds. Even if still have a blackscreen open samsung kies or switch. One of them has the emergency recovery option. It will detect it then and will say something like you need to repair the software want to continue etc. Lwt it do its thing and make sure you are on the internet. You drink some coffee and give it 30 minuts atleast.
Still not work? Try to put in a spare battery or charge it with another phone. If that not even works. I cant help you.
First of all, I do not have a battery that I can remove. I tried to enter download mode and recovery mode but nothing worked. It will not boot up into any mode.
Just hold the button combination for download mode for 10sec and connect it to a PC with installed smart switch on it. Smart switch should detect your phone, even if the display of the phone stays black.
I tried what you recommended but nothing works still.
I seem to have encountered the same problem, albeit not through exactly the same method. Essentially I managed a full stock firmware flash through ODIN, all the right messages came up and I got a pass from Odin. The phone rebooted and brought up the blue "updating" screen, which very quickly changed to a "removing" screen, at which point the phone froze. When I tried to reboot, the screen went black and now.... nothing. No recovery, no download, no light to indicate that its charging... nothing. My computer doesn't register there is even a device attached.
I've done heaps of flashing and never seen anything like this!
Would greatly appreciate any advice or assistance!
same issue here accept i was just using odin like usual. anyone figure this out yet? the phone was not rooted or anything. i had flashed the g935u firmware and then decided to put it back to stock g935t firmware. then it started doing this.
reflash but this time it check nand erase all
NEVVER EVER CHECK NAND ERASE ALL, dont advise others what you don't know yourself. This is for manufacturer and is not intended for repairing, if you nand erase your phone its just a paper weight then, beyond recoverable. But this issue is caused by wrong partitioning i suppose, but still it must go in download mode, try plugging it in when smartswitch is open in pc while holding home+vol down+power , if it wont detect then i suppose its nand failure due to any reason. And motherboard replacement is required.

If it really did nand erased all, your phone wouldn't even boot, your phone working is a proof it isn't nand erased. What people don't understand is that nand isn't the internal memory, its the non volatile memory holding vital info about functioning of phone just like a bios of computer, so if it is erased you are beyond recoverable damage. Here , i must say i dont know if odin can really nand erase all, because if your phone is working, nand is definitely not erased. And as far as what fixed your issues, there must have been some other reason. But for everyone, leave that option empty just to be safe.

Ofcourse it doesn't effect S7 edge, because it DOESNOT wipes the nand.. so its not working simply..
On older phones it will wipe nand totally and thats a dead brick..
First search what nand is.. its the non volatile memory.. or simply nand chip .. if you delete it.. your phone won't be a phone anymore.. its the non volatile memory that is equal to a bios of a computer.. delete non volatile memory and your phone is completely dead..
Thanks to the latest phones that don't erase non volatile memory and instead selecting nand erase with s7 edge simply deletes userdata before flashing.. which is equal to a normal hard reset ..

Please help! Soft bricked, unrooted, untouched, 100% stock phone brick during update

I am in need of serious help! I dropped my phone off a 2nd story, smashed the screen completely. So I took my wife's old stylo 2 plus (exact same phone) stuck my Sim and SD into it, registered through metro pcs, and it worked great.
I did software update because I was really excited (my old stylo 2 was rooted and had many problems along with being unable to update android software).
Update took about an hour, then said failed. After that it has been unable to boot up. I tried recovery mode, it offers to factory reset. Again reboots and stuck at logo screen. Says error device is corrupt, cannot be trusted, will not boot. I press power it says press power again to boot anyway. Restarts and sticks at logo screen. Device is basically untouched. No oem unlock, no debugging, no developer options, nothing has been touched ever, the phone is 100% stock. I even did factory reset before I started using the phone.
Can someone please help me at the least flash trip so I can fix this??
I am not new to this, but has been 5 years since I flashed anything. The problem is, is that it's still locked, and can't boot up. The phones bricked and never been touched!
If I can get twrp flashed I can go from there, I need a way to unlock it, or flash without unlocking.
Please help me I need my phone for work. I'd rather not switch back to an old smashed screen

You need to download the kdz(device firmware) and flash it in download mode using lg up.
Sorry for the super long delay. I did what you said, and was able to use my phone again in no time. Thank you very much!

set warranty bit: kernel error and imei theft

hello, i had a samsung j5 (sm-j500f) its imei has been stolen. i contacted with samsung and they said we can restore your imei if you have it. unfortunately, its box is missing and sticker under the battery erased, so we couldnt figure it out that way. we throw that phone away for a while. a couple days ago i found it and i wanted to give it another chance, but it doesnt open now, no reaction for any button conbination (recovery or download mode) and says set warranty bit: kernel. i realized, this error mostly occurs due to custom rom flashes etc. but in my case, there is no such thing. i was using it with official software. i wonder are these two things (error and imei theft) might be related or is there totally another situation here? are there any chances for getting this phone back to life?

Its normal, you cant fix it. Its not an error, its just the system showing a mini debug interface. Where did you get the phone from? Someone else used it? Bcs they tried to install a custom ROM on it, failed and just left it as that. If you shut down the phone, hold down Powerup button, down volume and home button you will enter download mode where you can install stock ROM and fix this soft brick. Follow this

thanks for the answer mate, but i guess i needed to give a little bit detail for the problem. i was the first user of the phone, i bought from store not from someone else. so it had original software from the beginning. i am aware these kind of issues mostly caused by flashing custom roms etc. but this is different. i contacted with samsung customer support when this happened and they said they can fix and give its imei number if i give the imei but unfortunately i had nothing. i couldnt find phone box and the sticker under the battery was faded out. i put the phone away for a while and a couple days ago, i found it and wanted to try my luck one more time. one the other hand, you mentioned download mode but i tried all button combinations and no response. if i can enter download mode, i probably would have been flashed original software, but still there is imei problem. i guess i will let this phone go. i cant find any other solution.

Turned this phone into a brick and I need to fix it!

Hi, so, I got this phone from a friend, and he told me that the phone was working prorperly, but after someone factory resetted it, he wasn't able to set it up. Constant force close pop-ups where showing up while setting it up, and you weren't able to accept terms and conditions (button grayed out). Also, one thing I noticed. The phone got into "Factory Mode". Idk what that is, but it wouldn't let me to enable wifi or bluetooth. That little Factory mode thingy got me really confused. Also, I wanted to boot into recovery mode, and I wasn't able to do so. After turning the phone off, and doing the key combo to boot into recovery, the phone rebooted itself (very showrtly after doing the startup vibration) and after that, it seemd to get into recovery, but it stayed at the android logo with an exclamation sign and after 3 seconds it rebooted itself to system.
After that I said, "well, last thing to try is flashing stock rom again". And I did so. Using the Frija software to download the latest version of android for this phone (and using the corect CSC for this phone (CTI)). I used odin 3.12.7 (wich I knew it works because of previously using it with other phones) to flash the stock rom again. I made sure that only Auto-reboot and F.reset time were checked, and started flashing. After it finished, it got to the samsung logo, but got stuck there. Nothing happened (I left the phone there for like 30 min). I decided to hard-reboot the phone and try to factory-reset it, but after shutting it down, it started to be really hard to make the phone turn on. I had to unplug the battery and wait like 10 mins to try again, and I still wasnt able to boot into recovery mode. It just got stuck at the "Galaxy Core 2" logo.
After that first boot, the phone never got passed the "Galaxy Core 2" logo. Just stuck there. After that, things just begun to get worse. It was also hard to get the phone to get into download mode, most of the time it just stayed at a blackscreen (im not shure if the phone ever turned on, but it never vibrated) and did nothing. I decided to try other versions of odin. Tried with 3.09 and 3.04. Nothing, and after every flash, it got harder and harder to make the phone boot.
At this point, I can hardly get the phone into download mode, and if I do so, sometimes I get the odin complete write operation failed error, wich the only way that I've found to solve it is to reboot again the phone into download mode.
I know that the battery is working, I have another core 2 (same exact model) and battery is ok. At this moment I don't know what else to do. Please, help me to get this brick of a phone back to working conditions, I dont want my friend to buy a new phone just to use it to recive calls and charge it.
Some extra notes:
As i've read, sometimes this can be caused by the replacement of the digitizer/screen. This phone seems to have one or both of them replaced, since I can see glue residues on the corners of the glass, where it touches with the plastic frame.
If there is anything hardware related thing to try, I can try to open the phone. I have some experience doing so.
EDIT: As I continued reading through this forum, I found out that some people had luck with Odin3_v3.13.1_3B_PatcheD, so I decided to try it out and see. Still, nothing changed. As today, I can only use this phone to charge the battery (it dosent actually show the percentage, only the battery icon with a loading icon inside) and boot into download mode
Although, I have to say that after flashing the stock rom with that version of odin made the phone not that hard to start in download mode. I think that it could be something that got corrupted on the eMMC module and it has to repartition it all again...? Does anyone know how to do so?
Regards
Well, tried almost everithing I know. Downloaded rom again with binary nature, tried with odin version 3.12.7, 3.13.1_3b patched and 3.13.3, but nothing. Extracted the PIT file from the CSC file, did repartition, NAND wipe, and nothing changed. I have to say that its certaily easier to get the phone in download mode, but thats almost it. One thing to note, when i select the NAND wipe, it dosent seems to do anything. I mean, in odin Log screen some things appear related to NAND wiping and such, but its really fast and there are only 2 or 3 lines dedicated to that. Is that OK?
Anyway, please, any recoomendation or thing to try would be great, since this phone is now trash, it dosent matters if it starts to get worse, or even unusable (more than it is rn).
Regards
