Bricked S7 SM-G930T - T-Mobile Samsung Galaxy S7 Questions & Answers

Hey folks,
Got a bit of a problem. Seem to have bricked my S7. Which is a bit of a problem.
I was following this guide;
https://theunlockr.com/2016/09/03/ro...xy-s7-s7-edge/
Which borked once I flashed it via Odin.
So I went about google how to take this back. Tried to follow this;
https://forum.xda-developers.com/gal...xy-s7-t3600380
Failed half way through reflash and now comes up with;
"An error has occured while updating the device softwareuse the emergecy recovery function in the smart switch PC Software"
So i found this guide: https://www.youtube.com/watch?v=1yXQUFrEWg4
So I download the Smart switch software and get to device initialisation and then it asks for my Serial Number. Which, I can't get because it's in the software of the phone. There's no external Serial number. I think if I could get an SN for a SM-G930T phone I might still have a shot at saving this.
Can anyone help me with this? I'd rally, really appreciate it.

Just found this which could be useful if I could get into the download bit, which I can't seem to be able to anymore.

https://forum.xda-developers.com/tmo...store-t3367007
This too looks useful, again, only if I can get back to the download screen.

Could anyone send me an SN for an SM-G930T so I could get the emergency software recovery to work? That would be great.

It's not on the back of this phone. I also got this second hand from Ebay and so didn't have a box. So, I just found one on the internet and that has worked.
I've managed to get it back working... but I don't want to talk too soon. it's taking me through the usual startup stuff but I'm not out of the woods yet... This has been a hair raising adventure so far and I'm absolutely no further forward than I started.
Not ideal finding a random SN tht matches your model number but we will see if that has any lasting repurcussions. In the meantime, it appears to have got me out of a hole.

Don't suppose you can link me to a rooting process for the SM-G930T could you?

So I have a SM-G930T on Android 7 (Nougat) and I'm looking to root it ultimately to make some changes about tethering identification as I did with my former Z2 and posted a solution on how to do that.
Any help would be grately appreciated.

There's the video. Will be investigating this further later.

when you boot in download mode, press the home button before you press confirm, it will give u your serial and imei

Useful info... but sadly not what is needed I'm afraid.

As it happens, doing those steps, my SN shows blank.

[Q] Huawei H866C Question

Hello everyone!
I seem to have a big problem with my phone that I cannot figure out. I'm fairly good with phones and very good with PC, but this problem eludes me.
My Huawei H866C was working just fine yesterday until boom, system freeze. This happened numerous times and most of the time, all I was doing was looking around in the settings etc. My first gut reaction was to factory reset it.
So I did.
When it was done, the phone rebooted like it should, and there I found the "tutorial" screen.
I tap the green android and it proceeds to the next screen which has only one button labeled "Begin"
When I press begin, it immediately throws this error; The application SetupWizardEx (process com.huawei.setupwizardex) has stopped unexpectedly. Please try again.
Well, needless to say, I've many dozens of times with no success.
I recall a similar incident with my sisters motorola droid bionic, in which after a reset the phone wanted some carrier info before it would load the home screen and let you use the phone. With that incident, I was able to bypass it by touching all 4 corners of the touchscreen. I can't find anything like that to bypass this tutorial nonsense.
I know that the phone isn't bricked, because I never rooted it. Furthermore, I can still bring up swype keyboard settings by holding the menu softkey. From there, I can click a web link in swype help and open the browser with no wifi connectivity. I can go through browser settings, and swype settings. When I first turn the phone back on, I can even use the slide-down menu briefly before it takes away my access.
I was really starting to like this phone until now.
Is there any way to bypass this annoying tutorial so I can use the phone? Otherwise, I'm afraid my money was wasted.
I have included some fairly low quality pictures to try and illustrate my problem.
ANY help at all would be greatly appreciated.

Well admins, you may as well delete this thread. It's helped no one, including myself. I'm just going to return the phone and get my money back..

Click to expand...
Click to collapse
And that's exactly what I did. My best advice? STAY AWAY FROM TRACFONE/NET10/Straight Talk at ALL costs! Sure, they give you cheap unlimited everything, but the phones are pure garbage. :good:

No service with valid sim card

Hi everyone,
I'm having a very bad issue with my Nexus 5.
Last week, my mobile network stopped working, always displaying "No service".
The sim card was still recognized, since I had to enter my pin code after each reboot.
So I tried to put my sim card in a friend's phone, and it worked perfectly on his.
Next, I called Google tech support to get some information and they simply sent me another Nexus 5 to solve the issue.
The thing is, I'm having the same issue with the new phone, but it's even worse.
The sim card is not recognized at first when I reboot the phone.
After I put it out and in once, it asks me for my pin code. And then, I get the "No service" again.
If I try to make a call it says : "Turn off airplane mode to make a call" (see attached screenshot). I tried to turn it on and off, nothing works.
I must precise that the network worked as a charm with the new phone for 3 days and then nothing.
I tried several sim cards from different service providers, and I get the exact same issue every time. and boot in safe mode but i get the no service again

Here is my configuration :
Android 6.0.1
Security patch level : 1 january. 2016
Baseband version : M8974A-2.0.50.2.28
Build number number : MMB29S
Is anyone having this issue ?
Thanks.
There is a known problem with the N5 where a totally dead battery can kill the radio component. No, it makes no sense to me either, but after it happened to me I did a lot of reading across many forums and discovered I wasn't alone. Flashing half a dozen different ROMs made no difference. Eventually I contacted Google and, as with you, they replaced my N5 with a refurbished model which has worked perfectly ever since.
All I can suggest is that you report the second phone to Google and hope that they will replace it again.

Moved thread please delete this. Ty

Moving thread .... don't believe its a sprint issue
I switched from sprint to T-Mobile. They screwed up and let us keep our old phones and did a discount for the hassle. I figure I don't need 2 S8's so I would just sell it. Welcome to my nightmare.....
So I factory reset the phone to get all my data off, I did this through the settings menu. No issues the phone reset. It was at the beginning new phone screen so I just left it and placed the phone on craigslist.
I get a buyer and we meet at the store. The lady who works at sprint and was going to verify the phone was not stolen starts the phone and asks me for the password..........huh?....
The phone is at a password screen and I have maybe 5 at most that I use various combos of, none of these work. She brings it over to the "techs" there are they say they have never seen this. I then apologize the the man who wanted to buy the phone and proceed home. I do some searching online and find out how to get into certain menus and do resets, and re-flash the stock rom. Even after those it wants a password.
I then think I'll just use find my phone with good and unlock it. Well it is a sprint phone and I have T-Mobile now so it has no connection, and I can't get past the password to get to the wifi settings. So google says it can't find my phone.
I contact Samsung and since it’s been less than a year they say they will help. I send in the phone and they send me it back with the crack on the back of the phone fixed and nothing else. I called and they said they have record of me asking for help with a password problem. I then ask if I can send it back and get that taken care of and they said it would cost 150$ because they fixed the phone......huh?
I really just want this password off the phone. At this point it’s a matter of I am more curious about finding a way to get it off the phone than selling it. I’m also open to all ideas. Taking it apart, flashing something third party on it.
If you need pictures I will get them up shortly. Or a video. At work currently, so I can probably reply in a timely manner. If you need more info please ask and I’ll try and get whatever you need
Thanks in advance

FRP locked SM-G930w8 ( disabled OEM unlock on custom ROM )

Hello all,
From what I can tell XDADevelopers is the best place to ask stupid questions - because I'm noticing with how much time I've spent on here trying to solve this problem that everyone here seems to be particularly helpful! However, I have spent way too much time trying to solve this myself, so this is my last ditch effort before I go and buy myself a new phone, haha. If anyone can get this phone working again for me I will PayPal, send some BTC, or eTransfer ( if you're in Canada ) for your time!
So here goes:
I installed an 8.0 Oreo Superman ROM ( I don't remember the exact one I flashed - IIRC it was this one but I'm not entirely sure, but it was working really well and I was extremely satisfied with how everything was working ). Now I did this a while ago and I've been extraordinarily busy lately so it's been a while, so forgive the lack of detail. I was trying to install some sort of application/feature through Magisk Manager and it wasn't working as expected so I did what in hindsight what I know now to be an incredibly stupid idea - which was to disable OEM Unlock and disable developer options and reboot hoping it would get whatever I was attempting to install working. Instead I was greeted immediately to the following bootloop upon starting the phone again:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
( here's a direct link just in case since the thread preview isn't showing the image for whatever reason: https://i.gyazo.com/1a8af44f100198c70ef9ebfc98fea374.jpg )
I'm unable to boot into TWRP and Odin/PC does not recognize the phone at all. I've tried on multiple computers, different cables, etc. My other Samsung S7 has no trouble being recognized by my PC & Odin as well as Samsung Kies, so I know it's not a driver issue. I only have the IMEI engraved on the back of the phone since I have long lost the box that had the SN on it, which might allow me to reset it through Kies as far as I understand. I am starting to think this is well beyond my capabilities to fix, or the phone could potentially be completely bricked. But again, that's why I'm here asking for advice.
I have tried my best to solve this on my own but I simply don't have time to keep working on this - so like I said, I'd be willing to pay to have someone attempt to come up with a fix for this issue or at least tell me I need to go and buy a new phone - though, ideally I'd prefer the former, haha. If the phone is toast, I was thinking of getting a lightly used Xiaomi Mi Mix 2 off Kijiji or Ebay or something - but if anyone has any recommendations for an alternative I am open to that as well, but I like the bezel-less design and the fingerprint reader, but ideally I'd like an OLED and wireless charging.
Anyways, hopefully someone on here has a solution or at least tell me with 100% confidence that I can safely toss this phone and I will keep my fingers crossed....
Thanks guys - any help would be greatly appreciated.

[HELP!] eMMC Software Download App problems with Nokia 8 (No Phone. State stuck) :(

Hi everyone!
For almost a couple of months I have been dealing with my bricked Nokia 8, it became like this on its own, I did absolutely nothing to it, this is one of the greatest mysteries I've come across and been living in misery since.
If you want to know the full extent and description, you can check it in my original post here: https://forum.xda-developers.com/nokia-8/help/help-nokia-8-powering-unresponsive-t3993959
Since then I have posted in the Noob thread and have been communicating with others, to the point that I've been trying my phone out with QPST, in particular the eMMC Software Download App. The reason being that I am wanting to gain access to my deep internal storage and do a full backup of the device, before I do any flashing or repairing to unbrick that would erase my data completely (I am in desperate need to retrieve my contacts and SMS messages as they are not backed up online or offline. It is also making my work life incredibly difficult and loosing out on jobs )
Long story short, my Nokia 8 gets recognised in device manager in 15 minutes after connected by USB as Qualcomm 9008 (before it was QSUSB_BULK but I installed the Qualcomm drivers manually).
I then proceed to open emmc software download app, and after wanting to "Switch device to DLOAD" I get this happening:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It remains in that state with no progression (looks like 20%) and I have tried this again and after leaving it for more than 2 hours it's still the same and gives me this error message after selecting Okay.
However, if I unplug and re-plug USB, then open again emmc software download app, and then click DLOAD button to select phone, I get this:
The State is now Enabled but no more Q/QCP-XXX (Sahara Download), it just says No Phone.
Any idea what this means???
Does anyone know if they may have experienced this whatsoever? And if anyone can help me on this??
I would really really appreciate it!
