Please Help I broke my phone - Samsung Galaxy S7 Questions and Answers

Hi XDA forum,
So yesterday I tried to root my phone and disaster struck. Now the phone is stuck in a bootloop where it turns on and off and on again indefinitely. I can still boot to recovery mode however. I tried to use factory reset and then reboot but I run into the same problem.
I figured that I would need to put the stock Firmware back on, and went and downloaded this: [I cant post links yet but it was the SM-G930V from sammobile .com] Because Etched on the back of my phone is Samsung SM-G930V
However, when I try to download that using Odin (Prince Comsy Version) it fails and I get a message on my phone "unsupport dev_type"
That is definitely the model type that is etched on the back of my phone.
Any ideas on what I am doing wrong/how I can get my phone to work again?
I would REALLY appreciate any help.
EDIT: this is my first post here, if it is in the wrong place please let me know.

What model does your phone say it is in download mode? It's the end all source of truth.
The firmware you're flashing, is it the latest? The G930V can't flash back to older versions, so you either have to be flashing the same version or newer from sammobile

Thanks so much for the reply!
I was trying the latest version yes. Where exactly will the phone say what model it is in download mode? I haven't seen that anywhere and that might be the issue.

Download mode should be a blue screen with text and an arrow in the background, the phone info including model will be in the top left like https://imgur.com/lvqQmws
It should be in download mode if you're trying to flash anything.
If you're in recovery you're in the wrong place (iirc they use the same button combo, but recovery is volume up, while download mode is volume down)

[Q] Bricked Tablet - see post for details

Here is the sequence of events:
Galaxy tab 2 10.1 with factory rom (wife's tablet)
Wife tells me that she keeps trying to complete the update everytime she gets prompted, but it always fails
Wife also tells me that she can't power off the tablet (she presses the power button, it shuts down, but then it starts up again)
I try the upgrade, get same result as wife
I try to reset the rom: I download what I think is the correct file, download Odin 1.85, and run it.
put tablet into download mode, attempt to use Odin to load new rom ***note, this is probably where I screwed up, as I am not sure i used the correct file. This is the file I used: PDA_HC31_EG01Ba_AP352081user_CP1033580_LTE20110704_0708.tar, which I found in a search on xda forums for my problem.
Odin reported failure. I tried again, same result.
I tried using KIES, using the Firmware upgrade and intitialisation (note that I must have UK version of KIEs, based on the spelling of initialisation--maybe that's a problem??/). I put in the model number, then the serial number if the tablet, get a message that GT-P5113 does not support initializing
tablet displays the message: Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again.
I try to put tablet back into download mode, but that doesn't work. Any suggestions on what to do at this point? Appreciate a step-by-step solution, if possible.
Thanks!

Seems you flashed a wrong file.
Download another rom from http://live.samsung-updates.com/
and reflash with odin
Last week i tried to update my tab from 4.1.2 to 4.2.2 it hangup while flashing. Had to reset but then end up with firmware upgrade encountered blablabla. I just reflash within the blind screen without download mode and got it to work again
But don't I need to get the tablet into download mode first?

That makes sense, but how do I get the correct file to the tablet if I can't get the tablet into download mode?

If it's really a gt-p5113 then find the 1 for your country. If you're not sure your region code/csc then just download for any region.
You will know what i'm talking about if take a look at the given link
Please look at item 10 on my list

I can't load ANY file to the tablet, as I CANNOT GET IT INTO DOWNLOAD MODE. I need to know how to force the tablet into download mode. Pressing POWER and VOLUME DOWN does not work. NOTHING HAPPENS.
Connect to PC on the screen "firmware upgrade encountered blablabl" Downloadmode on in Background, Odin can get access
If you are working with Odin, please kil ALL Samsung and KIES Programs and Services running in Background.
Hi for go to download mode you have to press power and volume up buttons

I have tried this many times and Odin just fails. TWRP, CWM, Phil's touch all tried and failed. I have tried so many ROMs not sure I could list 'em all. Wanted to try SlimKat. But have this same problem, can't find the handle now, I only get the firmware upgrade encountered blah, blah. I'm just about ready to make confetti out of it! Can I get assistance with this problem, please. I don't care what ROM I have to run, I just need it to work...
Any solution to your problem?

None as yet, I'm running out of real estate to search...
The rom you used in your op was probably for a data tab like sprint, att, Verizon, that is usually a brick result.
If you could factory reset you may have a chance but I doubt it without recovery or download mode.
Pp
You are faceing the "black screen of death" ("Firmware upgrade encountered an issue....").
Uninstall kies and reboot your pc.
Start odin.
Connect the tab running the black screen of death (BSOD).
Download mode running in background of BSOD so odin will detect your device.
Flash the correct firmware now and pray flashing the at&t rom didn't caused a hardbrick.

Correct rom
I think that is exactly my problem. Last night I got Odin to run all the way through, it said pass but still no soap. I'm just about to list it for parts and at least minimize my loss.

[Q] no battery pull precludes recovery

I tried to use chainroot, and got stuck on the logo screen. normally you'd battery pull, go to recovery and wipe data. but i can't find any way to shut down the phone, before doing power-upVol-home.
And now i've tried to odin a stock recovery to undo chainroot, odin fails. could re-run odin with auto-reboot off, but again, no way to shut off and go to recovery.
at this point i'm stuck with the blue screen asking me to use smart switch on PC to do emergency recovery. but smartswitch says the device is not recognized.
thoughts? thanks!
I was stuck rooting on the boot logo too. Had to use odin 3.10 and did "run as administrator". Also if this helps to reboot the stuck phone press vol down+power together until the screen blanks out. If you need to get into download mode, as soon as the screen blanks out, press and hold the Home button ( Don't let go of the vol down and power though ).
Good grief.... the non-removable battery has made these recovery tricks so difficult
thanks twisted_mind. at this point, i only get the blue screen asking me to do smartswitch recovery, and the one thing i CAN seem to do is volDown-power-home and it easily goes to download mode. i have not been able to get to recovery mode no matter what i do (including volUp-power-home, even before this smartswitch message came up after i tried to odin a stock recovery).
so i can still go to dload mode, and stick in a stock rom. the ones i've tried are from sammobile, and a potential issue is that i don't know the exact one to pick (this phone is a demo here in europe and i didn't note the details under settings when it was working). so the ones i try end in an odin FAIL. again, i've also tried odin unchecking auto-reboot, but then the phone is stuck at the very end of dload ("don't turn off target", etc), and i have no way to battery pull, etc.
Instead of holding power to shut off you have to hold power and vol down

Hello

Thanks

I have the turquoise screen that says "an error has occurred... use the emergency recovery function in smart switch...". if i do power + volDown there OR when the phone is stuck in download mode after the odin fail, the phone turns off but then comes right back on with the turquoise error screen. i've tried quickly going to the recovery key combo right when or right after the screen goes dark, but to no avail.
I can easily do power +volDown + home and go to dload mode. i just can't get into recovery mode no matter what i've tried so far.
if i could just find a stock rom that wouldn't fail in odin, or something else to use as AP/PDA in odin, i'd be set i think. wish i knew how to do this. hitting nand erase all in odin doesn't do the trick by the way.

is the version you flashed the same version that you had prior (do the apps look the same, etc)?
so odin passed? (mine FAILs, with 4 different sammobile stock recoveries). I have the S6 Edge, maybe the S6 works fine and I just need the correct S6 Edge firmware.

store apps was pre installed in the rom nothing more.
Odin passed normally with no issue.
i used two identical Odin v3.10.6 versions the second one i used is the one i flashed the rom and the root with.

[Q][HELP] Very bricked, please help

I have a GT-P1500, and I flashed a ROM .zip to /system with heimdall before I really grasped how flashing these kinds of things on samsung devices really works. Now everything is terrible.
I can boot into download mode and heimdall and odin both recognize my device. When I flash a recovery, I'm not able to boot into it even when I do the right key combinations and it says "booting recovery" in blue text in the corner on the samsung logo screen. Also, for some reason my download screen says "qualcomm secureboot: enabled" at the bottom of the other stuff. This is normal, right?
I've tried flashing the .tar.md5 firmware files from sammobile, but odin fails to flash them. I've tried kies, but it doesn't recognize my device. I've tried different computers. I've tried different recovery builds. I've tried everything I can think of.
Please help?

No problem my friend, but I just saw you mentioned p1500 and this p5100 thread. Sorry, i missed that too.
http://forum.xda-developers.com/galaxy-tab-10-1
Your problems will be sorted out there better than here.
Although I don't see any help or advice in your case. Since I am pretty sure you are on a carrier locked bootloader, sorry to be the one to break this on you which means you can't go custom and the carrier company is the real owner who doesn't want you to leave them.
Ah, 1500 was a typo. I meant 5100
Also, I can't do anything to the bootloader to fix this? Not even go back to stock?

There must be something, you got me mixed up with P1500 . well, lets put few confusions to rest
what else do you have, I will need more details
Are you using a carrier locked tab 2 p5100?
or did you flash a carrier locked firmware on your unlocked tab?
you mentioned you flashed a rom zip from heimdall. which one exactly?
is your device booting up or you are just stuck in download mode?
The tablet boots, but the screen is just black and I can only try rebooting it. I can boot into download mode by holding power and volume down.
I do not have a carrier locked version, and I have not flashed any firmware packages as something eventually goes wrong and heimdall or odin stops there.
The device was booting into stock properly before I flashed the ROM incorrectly. I flashed the 5100 version of the ROM here: http://forum.xda-developers.com/galaxy-tab-2/10-inch-development/rom-cyanogenmod-13-cm13-0-t3303800

Update your bootloader to jelly bean. Flash from odin.
http://forum.xda-developers.com/showthread.php?t=2642005
Refer to this. Will work, no need to worry.
Sorry for replying so late, I have been really busy lately.
I am unable to update my bootloader: odin either outright fails or hangs on SetupConnection forever. After weeks of recearch and attempts, I see no answer. I guess I really am bricked forever? Damn.

Urgent help needed odin fail

Hi all I will keep it brief.
I have tried to flash with Odin 3.10.6, 3.10.7, 3.09, 3.10 root, twrp, stock firmware G920F but everything fails at "Nand Write Start" its driving me crazy. I've tried different versions of Odin, Twrp, and even Smart switch multiple times but nothing will write to the phone. ODIN ALWAYS FAILS AT NAND WRITE START.
My phone will only boot into download and NOTHING else not even recovery.
Any help welcome......
Try different firmware revisions. You flashing stock? What was the last fw successfully flashed?
Sent from my SM-G920F using Tapatalk
It is Stock G920F (united kingdom EE (EVR).
My problem is No matter what version of Odin or what I try to flash Odin always fails after Nand Write Start. It's not just the stock firmware, it's anything I try to flash in download mode.
Im actually in the same boat just now. ODIN wont flash the EVR Firmware (previously it did, mine fails on the cm.bin). I have tried different ODIN versions and also different laptops. Also the Smart Switch / Kies3 recovery procedure didnt work for me either. I was able to flash TWRP via down and get into recovery, but it see a lot of unable to mounts when trying to flash custom ROM and fails to do so. I think that i might have stupidly wiped via recovery something i should not have as i did noticed before all this i lost me IMEI (unknown).
I always assumed that if you can get into download you would always be ok but this is the first time for me that im having big issues.
I really hope someone can help out other wise i have a really expensive paperweight.

Try to flash latest fw. Probably you've upgraded the bootloader to which cannot be downgraded.

What i've noticed with the S6 (and S7 i presume) is because you can't shut the phone down completely when your stuck on the download screen it never fully resets itself for another attempt at flashing by Odin. If your hold Power+Volume down to shut it off, the screen just goes black briefly then it comes back onto that error message about connecting it to Smart Switch for emergency recovery.
Smart Switch is a waste of time, it will download all the software for your device , say it's going to install then you get an error message telling you to use recovery code which of course it does not give you! So basically you just go round and round in circles with Odin and Smart Switch, i'm convinced it's not being able to shut the phone down completely that causing the problem of failed attempts.
Anyway something you might try that allowed me to flash G920F United Kingdom EE (EVR) PDP in the end. >>>
The phone battery eventually died, i waited for 10 minutes before charging it up to around 15% again, then i put it into Download mode, made sure my windows 10 laptop had "debugging" enabled at start up (i think this is why Nand Write Start is failing).
I loaded up ODIN 3.10.7 with "Cf auto root", connected my phone then flashed the root file straight away. It worked, so i reset Odin, put phone back in download mode and flashed EVR quickly via odin and it worked.
Over all i thin there's 2 issues here: The phone cannot be completely shut down when it will only boot to download or that smart switch recovery error and Windows 10 keeps turning off "debugging mode" which prevent Nand Write to device. I may be wrong but after hours of attempts with lots of different Odin and Firmware thats what i noticed. There has to be a way of shutting the S6 off completely .
NB: Tried latest BTU firmware, won't flash same problem "Nand Write Fail"
NB; Reactivation lock is OFF

There is no recovery code as far as I remember. As long as you have the sn that should make a go.
And there is no way to shutdown the phone completely. We can force reset but it will only shutdown whem the battery depleted.

Smart Switch is useless! I put in the model SM-G920F then the serial number and SS tells me the correct firmware is (EVR), downloads it, prepares it for installing, starts to install, gets to 1% then says "an error has occurred please use the Emergency code below to recover your phone" BUT there is no code! It says Emergency recovery code: .......nothing.
The main issue i'm experiencing is ODIN will not flash anything of any version, always fails at "Nand Write Start".
I've tried multiple versions of Odin, Stock Firmwares, TWRP, Root. Nothing will flash until the battery is dead, then when i try with a little charge for the first time Odin will usually flash the 1st file i give it (no matter what it is) then thats it, back to failing after "Nand Write Start".
Driving me crazy.
Quick update. I loaded a later FW (Still UK) and it passed in ODIN, so that was better.
But after that it booted into stock recovery, showed unable to mount efs (no sim card in). I then rebooted and its been on a blank screen ( with the blue light flashing) for the last 30mins. No real signs of life.
Cheers

The stock didn't flash correctly then. After you flash stock with ODIN it should reboot into recovery, should just boot into MM, and go through phone set up.
The problem with flashing different Stock firmware (even if it's same region) it can cause all sorts of issues. There's G920F BTU which is the non branded stock for Galaxy S6 G920F then there's G920F EE (EVR) G920F Vodafone (VOD) etc
You'd think the non branded BTU would be fine on any UK S6 but that's not the case unfortunately.
Use Smart Switch and go through the emergency recovery option, one you put in your model and serial number it actually tells you what stock firmware your phone was shipped with, then you find it and flash it through ODIN.

Already tried that. Flashing the EVR just doesnt work, ODIN Fails every time. Smart Switch says it should be EVR based on S/N but i just cant get it flashed.
Dont know what else to try.
Cheers
You might also try Win7 or earlier, 32-bit, if possible. There are known issues with Win8 and later.

Its WIN7 im using on both the work and personal laptop, neither of which have had any issues in the past.
IF i flash EVR, it fails, i then flash TWRP to reboot into Recovery, but i see there alot of unable to mount / error messages, possibly the partitions are damaged? I dont know.
cheers

My phone (SM-G955F) wont enter recovery mode, and wont restore back to stock firmware

Dear mods if this is wrong place please by god move it to the correct place
Hello, so I flashed the latest TWRP recovery to my phone but it gave me errors so went back and forth to stock firmware just to try to get it work.
so Finally I flashed an older TWRP recovery through Odin. after that my phone stopped going into recovery, so I tried to flash back to the latest version of TWRP through Odin. but this time I failed.
so I tried to do what I did earlier and tried to flash stock firmware but no Odin just gives me an instant fail when trying to flash back to stock.
and my phone now only boots into download mode but its useless as it stopped working on flashing the stock firmware...
and when not entering download mode its freezes on Samsung s8+ screen and wont go into recovery.
Is it a hardware failure maybe?
should also add I'm now at this wery moment downloading another firmware to see if I am able to flash that firmware on to this device, even tried using PIT files without a luck :/
Okay. I would recommend to restore back to stock before anything. Do that using smart switch from Samsung.
Phone needs to be in download mode and then you open smart switch and click on more. Then choose Emergency Software and Initialization. Now click on the*device Initialization*tab.
You'll need your s/n number which can be found on the back of your phone and you'll need build number.
Which is:
SM-G950F
or
SM-G955F for plus model
Sweet I am trying it right now and going to give feedback if it works
so any clue why TWRP gives me verification failed no matter what I trY, it litterly allways ends upp telling me to factory reset my phone
so here we go

it ended up as a fail saying that the device is not supported, im ****ed
It keeps saying that, everytime you try to restore using smart switch ?
Okay if.
Then, when you boot into Download mode. Reboot into download mode again, just fast.
With that i mean, hold ( Power, volume-down, bixby ) enter download mode, when youre in download mode, repeat (power, volume-down and bixby) and enter download mode.
That fixed my problem i had once, where it said fail with everything i tried to transfor with odin and with smart swtich.
Hope you understand.
Sorry, late reply. work
