[Q] Need help going back to stock, there's some complications with my phone now.

I've spent all day yesterday trying to fix this problem. I've downloaded gigs upon gigs of stock rom files, saw a ton of youtube videos etc. Still nothing.
So here's the deal. I had Cyanogenmod 10.2 on my phone for a while now and I've always had problems, although a nice rom but too many crashes, battery drainage etc. So I wanted to go to stock but before doing so I thought I'd give Cyanogenmod 11 a try and see how that works, which turns out to be worse and I lost all phone signal and data, pretty much no service. So now I tried to go back to stock for good. I downloaded the stock 4.1 something rom file, odin and tried going back which didn't work cause I would keep getting a fail sign on odin. By the way I tried different versions of Odin since that was suggested to me by my friend and that didn't do anything either. Then I read a blog about using Samsung Kies on my PC, now after I did that I got a message on kies that my phone encountered an error. Now when I turn my phone on I get a message "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
Is my phone bricked for good? Can I go back to stock? I'm not sure what else to do here now. Why is it hard finding a stock unrooted 4.3 rom for my phone on the internet? I also can't use that clockwork recovery mode either, it just gives me the message "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again" when I try going into that to even try and install Cyanogenmod again so I can use my phone until I find a solution to going back to stock.

Edit: Ok so I just installed clockworkmod recovery through odin and I was able to install a rooted stock rom through the recovery, but now the problem I'm encountering is that it gets stuck on the AT&T logo when booting up the phone. Installing stock rom through odin still gives me the fail message.
Edit 2: I tried installing a stock unrooted rom through recovery and it gave me some error but now the phone goes passed the AT&T logo after that however I have no service now. How do I fix that and how should I go about installing stock unrooted rom since Odin gives me the fail message?

The easiest way to fix it is to take it to a best buy store they will flash stock 4.3 on it free of charge, this is the advice that is now given by Samsung. Alternatively you could get the phone jtag'ed or while it says firmware upgrade encountered an issue it is in download mode and you can flash things with Odin. You can attempt to flash a recovery image to see if you can access recovery and flash enewman17's stock restore from the development section. You can also attempt to hard brick it with Odin by flashing stuff that has pre 4.3 bootloaders then use the debrick method here http://forum.xda-developers.com/showthread.php?t=2549068.
I recommend you try the best buy method first, then try to flash a recovery, then try to hard brick it and recover it and lastly to get it jtag'ed.
If you can't get it recovered after intentionally hard bricking it you haven't lost anything you were still going to need a jtag service but it might work.
Under the advice of Samsung I tried the same thing you did and they told me to take it to best buy to get it fixed, instead I hard bricked it then used the sd card method to debrick it. Which I had already done twice. But that method doesn't work for everyone I was lucky 3 times and had to jtag once(flashed the i747m bootloader bad idea had to jtag) since then I have quit pushing my luck and only flash things I know are safe for the phone.

Do you still have your IMEI on your phone or is it showing 0?

Go to settings, about device, what does it show for baseband? Then go to settings, status does the imei number for the phone show up, say unknown or 0? If it shows unknown for the baseband and imei you simply need to flash a modem. If it shows the correct baseband but your imei shows as 0 your imei has become corrupt search for imei restore the fresh a ton of threads about it most people loose lte after an imei restore but there is a fix for that too. If you are having problems with wifi try flashing a kernel.

I just did that and my phone is now hard bricked. Won't turn on at all, won't vibrate or anything. It's completely dead. Tried the sd card method and that's not working so far. So I need a jtag service for this. Not even sure what that is right now until I look that up after this reply. I did look into those usb jigs but it seems that's only if it's soft bricked.
Edit: Trying the sd card method on the 4th try worked. Now back to fixing this.

What did you flash that hard bricked your phone? A modem should have been pretty safe to flash. I have flashed a bunch of different ones the worst that ever happened to mine was no service or poor service.
What exactly still needs fixing? No service still? Did you check imei and baseband? Intact, unknown or 0? Will be available till about 7am off and on.

Oh man, I might be sounding like a total noob by now but damn I've never had problems installing custom roms and going back to stock before.
So I flashed a modem that was for my phone and carrier in some thread here and that hard bricked my phone when I rebooted my phone. I tried the sd card method and in the end that worked and I could start my phone but no service or anything which at this point is the least important thing. In that thread of the sd card method it mentions how to flash a bootloader to make the phone not require the sd card (which was requiring it on my phone to start up the phone) and now it's hard bricked by trying that, and the sd card is not making it boot into download or recovery mode at all now.
If only I had enough to buy another phone I would seriously punch this phone repeatedly until nothing was left. I've spent like 2 days on this phone now with about 5 hours not counting sleep of time away from fixing this phone.

Are you certain the battery is charged? Should be a question that should be un asked but it does happen. The bootloader you flashed you're sure was for your model and carrier(AT&T vs canadian)? If you flashed the wrong model bootloader then you will need to jtag, If not when I was debricking my phone I had to do a battery pull after each time I wanted the phone to boot with the debrick SD. Are you doing that I don't want you to feel stupid but if you have a lack of sleep and are frustrated simple things can be overlooked. My thought is that If the sd method worked before it should work now especially if you are using the same debrick image. Out of curiosity what model is your phone and carrier?
I wish you the best of luck and hope all works out.

Yeah the battery is charged, I've tried the battery on another phone as well. I do pull out the battery and all that, and yeah I know simple things can be overlooked. Which is why I tried again today. Oh well I guess it's just one of those things that just won't work for whatever reason. Anyways, my model is SGH-I747 for AT&T. I even made sure that none of it was the SGH-I747M. Oh well jtag is what it is, I guess I rather pay than have to deal with this problem. Only thing is that I've never done that before and so many people are offering it on ebay and I don't know who to go with, I mean I'm sending my phone to someone with no real guarantee or anything that I will get my phone back. And yeah there's user feedback but that could also mean a thousand fake accounts giving good reviews or friends and family giving good reviews for 1 penny sales. Anyone you suggest I go with? Either on ebay or out of ebay? Thanks for all the help btw.

Everything seems to be going downhill for me right now. My computer will not recognize any Micro SD or SD cards. It will recognize pro duo cards but not any SD or Micro SD card. I tried all my Micro SD cards and SD cards today and none of them are being detected although they do show up in MiniTool Partition Wizard. I even bought another card reader and it's the same thing. So now my computer is being a twat about this. I think I might as well just listen to some Linkin Park and slit my wrists to end it all. But before I do that, anyone know why my PC won't recognize SD and Micro SD all of a sudden?

[Q] Any idea how to fix this issue? I'm a noobie who has been trying to trouble shoot

I posted this on the Sprint Note 2 forum as well so I hope this isn't taken as me spamming
I have a Sph-L900 Sprint Galaxy Note 2. About a month ago the device started acting up Saying it couldn't connect to my Samsung Account, and the only way I was able to fix it was a factory reset. That soon turned into not being able to connect to my Google account and knox issues where something was trying to access my device administrator, and the only fix was to keep updating the samsung security police. The device began shutting off and restarting about two to three times a day with the same error notifications popping up on start up. I kept doing a factory reset in order to get ride of the issues but would reappear shortly after.
I have never tried to root my phone because I wanted to wait for my contract to be up before messing around with it.The most I have done is install a few 3rd party apps and use the google launcher apk as my everyday launcher. Eventually because it keep restarting so often I thought I would try to put cyanogenmod on it using the installer app.Unfortunately it kept saying it couldn't communicate with my device and had to abandon that option. A few hours later the phone restarted again but this time became stuck on the Samsung Galaxy Note 2 logo on start up. I tried to another factory reset hoping that would fix it but this is what happened
View attachment 2714536
The whole thing is in red and keeps saying error and fail.
I have no idea what the issue being a noob, but started looking through forums and posts hoping to get an answer. I thought trying to reload the stock rom might be my best bet and started looking into how to unbrick the phone on youtube and forums.
I downloaded Odin and tried [ROM][ODIN]SPH-L900 MK4 (MK4 Modem/Kernel/Bootloader/ROM - Full Restore - Unrooted), Galaxynote2root.com, and QBking77 methods and files for putting factory stock rom back on the phone. I spent all day trying each one only to get "nand write start fail" when trying each tar file on odin.
I wanted to see if someone might actually be able to explain to me the exact issue and hopefully a possible solution.

try entering download mode and connect it to kies and run the emergency firmware reset or something like that (it will ask you some numbers that are writen in the battery slot) try disabling antivirus also, it should work.
best,

When you tried to flash the stock with odin did you re-partition?

Upgrading to KITKAT on rooted Note II
Hi all, I want to install french KITKAT Rom through Odin. Before doing that I want to factory rest it with out external memory card, I believe if I do not do it, it would wipe off all the data from it. Is it possible to reset with out the card ?
Thanks for your help.

I didn't re-partition. I keep hearing i need a Pit file for that. Plus A) haven't found one and B) not really sure of the process of how to do so since the videos online keep saying not to select it

Need help fixing Soft Bricked Sprint Galaxy S III

Hi I was wondering if anyone here can help me in a very very annoying situation I got myself in. So pretty much I flashed a Lolipop ROM on my phone and it worked but i really didn't like that the camera didn't work, so I restored back to a backup I made of my original firmware. Everything seemed to be working but I was constantly getting Google Play crashes spammed at me each second... so I tried to wipe the device. At this point I didn't care about losing data I just wanted to have stock firmware and fresh device. It it nothing I ended up bricking my phone so now when I power it on it says, "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again. I'm a noob at this stuff and so for the last two days i've been searching for 'stock firmware' or 'stock ROMS' for Sprint Galaxy S III SPH-L710 I've downloaded these .tar.md5 files and tried flashing them with Odin but it always fails! It's so frustrating and I'm pretty sure it's an easy fix its just I'm so dumb to see it and I also can't use my phone :/... PLEASE HELP EVEN SUGGESTIONS ARE FINE......
Thanks

Can you get into download mode? Turn off the phone. Then press power + Volume Down + Home. If so, go to this site: http://www.sammobile.com/firmwares/confirm/41671/L710VPUDNJ2_L710SPRDNJ2_SPR/
Download the file, unzip, and then flash with ODIN. Make sure your phone is plugged into the computer and recognized in ODIN before flashing. The new version of ODIN, I think you load it in the PA slot and PDA in the old one. Make sure you are downloading hte file over a good connection and not a phone data.

Do you have the T variant of the phone? Look under the back cover and make sure that whatever you flash is specifically for your model number.

First time messing with my phone, and it looks super soft bricked.

Hello, first timer here. I have never tried rooting or anything, but today I finally decided to... and messed it up.
Verizon Samsung Note 2 SCH-i605 (yes, still.)
Got it on July 2nd, 2013, so I believe it was build 4.1.1 kernel 3.1? Not too sure on the legalities
Completely unrooted and unmodded
I was using kingo root and everything was fine until it hit about 52% on the rooting process when my computer lost connection with my phone. Since, it gave me the "Firmware upgrade encountered an issue" problem. So then I google-fu'd and followed directions of:
http://forum.xda-developers.com/showthread.php?t=2040264

http://forum.xda-developers.com/showthread.php?t=2582290
http://forum.xda-developers.com/showthread.php?t=2024207
etc.
and used Odin 3.10.7 (and 3.10.0 just in case, both on and off admin mode cause why not) on every single md5 available in all those links and the one from sammobile.com for sch-i605.
And each time, I would either received failure on "sboot.bin" or receive the "System Software Not Authorized" error if succeeded (it was stuck in bootload? too, kept flashing the logo then the error message). The VERY first time, however, it actually brought me to that page where I'm allowed to press things like erase cache, factory reset, or reboot my phone. There, I chose all those options in the order I've listed them. And ever since I haven't seen that screen again.
My issue seems to be every problem I can find put together, and can't seem to resolve it with my skills alone. I honestly don't care about recovering my data (which I believe is impossible now anyway) or rooting my phone. I just want it to turn on again.
Thanks in advance.
p.s. getting a new phone isn't an option currently
-edit-
Checked my verizon wireless software upgrade assistant for some info, and it says "Up to date" and "Version ND3" if that means anything to you pros out there.

Greetings,
Thank you for using XDA Assist. To get you the best possible assistance, I'm going to move this thread to your device's Q&A forum. Good luck!

install kies and try flashing rom. do you have rom from i.e. sammobile? use different odin versions and do not mark repartition

KIES is unable to read my phone (tried the bottom 3 versions of it), and I've tried running Odin 3.07 and unchecked repartition for every stock and restore md5s I had for my phone... the ones that didn't fail sboot.bin are still giving me unauthorized error.
I'll keep trying all the combinations, but it seems moot at this point.

Trying To Get Back To Stock

Hello everybody, I'm in way over my head here. A few months ago, I rooted my device using odin. I felt that this was fairly simple and I had no issues. Today, I tried updating the software and got a message that said something like "can not update as you have unauthorized software installed". I thought I had better unroot and that's where my problems begin.
I unrooted using supersu, , but it still would not let me download the software update. I thought that the recovery must be the issue, so I tried flashing back to the stock image using odin and now the thing won't even turn on. It goes through the samsung startup screens and then goes into a sequence of 3 or 4 error messages that all read something like "Unfortunately, dialer storage has stopped"
I don't think I've done irrepairable damage but I'm not sure where to go now. It doesn't want to boot into recovery but I can get into download mode. Any help is greatly appreciated!

Flash the stock firmware in Odin to go back to 100% stock. You'll have to find the stock firmware (kitkat or lollipop) in one of these forum threads or download it from sammobile.
Edit: You didn't mention which device you have (8.4 or 10.5; wifi or cellular). Below are stock firmwares for 8.4 and 10.5.

Thank you! I have the sm-t805w. I have downloaded the firmware from sammobile and will attempt to install it this evening. Do I need to install gapps as with nexus devices or is that included in the firmware files?
