Hi guys. I've rooted and flashed my s2 countless times and never had any problems, but i've now upgraded to my s4 and every time i've tried to flash a rom on it something has gone wrong. The first time i tried flashing fox hound and my 3G wouldn't work. I then tried flashing my backup and ended up bricking my device. After many long hours I managed to get my phone back to factory setting. A few weeks later I tried again with the google edition Kit Kat Rom, but then the play store wouldn't work. So I tried flashing my back up and yet again bricked my device and spent even longer fixing it. I don't know what I'm doing wrong.. I'm doing everything exactly as I'm told. So I thought I would give it one last try. So I've had to root my phone again, but now after I rooted it I'm not getting Superuser, SU or BusyBox... I'm running Root Checker and it;s not coming off the "Checking for root access" display. As you can probably tell I'm not the best when it comes to technology. If there's someone you can help get me on the right track I would be very grateful.
Oh and also, I've been hearing the words (Verizon and AT&T) etc and I don't know what type of phone i Have. All i know is it is an S4

Ok, so first off I rooted my previous phone (a Verizon Motorola Droid X2) without any problems ever. I dropped Verizon as my carrier and switched to Straight Talk and I bought the Samsung Galaxy S4, after a few months of having it I decided to look for a way to root it. After a few days of browsing and reading about I found and root option that worked. (http://forum.xda-developers.com/showthread.php?t=2565758) This saferoot worked and i had superuser and was able to do everything i wanted to.
I then went on the Google play store and installed apps that I previously had on my old device for rooted phones. Well I installed chainfire3D and opened it up and clicked install the drives (which then requires a reboot) after a sort time I noticed my phone was stuck on the loading screen and I can't get past it.
I then start looking for a unroot/unbrick option in order to restore my phone to default firmware and factory settings to get it to work again.
Now here is the dilemma...
Like it says in the title, the phone model is SGH-S970G and for the life of me I can't find this model's firmware anywhere.
plz help me asap!!!!
Thank you in advance for any useful information to help point me in the right direction or give me a solution!

If you get your phone fixed, I suggest you skip reinstalling Chainfire 3D. It specifically says it's not for Jelly Bean devices.
UPDATE...
nvm, delete this thread i guess. redid entire process second time, maybe got impatient first time. now, installing cf/SU and ti backup seem to work as they should, ti backup asking for root access and happily doing its thing now, which would have to mean the phone is rooted, yeah? heh.. whats what i get for brainlessly taking the OTA update recently without thinking before acting.
---------------------------------------------------------------------------------
stock (i guess) galaxy S5, ATT, ANG3 update recently.
total brainfart. wasnt thinking about root which id kinda forgot about and wasnt super concerned about, even though its always been on the to do list.
im using this method...
http://forum.xda-developers.com/att-galaxy-s5/general/g900and3tong3keeprootota-zip-t2862299
and the process of flashing seems to work fine BUT after going back to the older firmware, it still shows NG3.
why is that? i cant even tell if its actually rooting the phone, even though towelroot (when used like the guide says) doesnt return an error or reboot the phone.
phone isnt bricked, still works fine.. calls email wifi etc. its just not DOING anything. NG3 preventing going backwards, perhaps?
There are many threads that focus on this same issue I have run into. I am posting this now because there isn't anything that has been posted this recent. I literally spent three days trying to find a solution.
What I did to mess this up with my S4 I337m Fido phone.
1. Odin install TWRP recovery. This seemed to work fine. I think I had to flash it twice to get it to work but I could boot to recover no problem.
2. CF-Auto Root
This process worked up to the point where you are suppose to reboot the phone and open the Su App and allow it to write permissions. This failed to work. Every time I booted my phone it would lag out and tell me SU app failed to open.
3. Flashed Slim KAT anyway...bad idea but I figured I would follow proper steps and flash. Everything was fine except for WIFI...yes everything seemed to be running smooth except for WIFI. This was obviously unacceptable.
4. Flashed stock ROM for my S4 which I received from a thread and then updated with Kies to obtain fully stock. This by the way is a suggested fix from many threads but this is where the sounds stopped working!!! Yes WIFI was good but SOUND was gone!!! WTF!
5. Flashed like 4 different froms ranging from CM11 to Mokee ROM....Nothing worked.
FIX! So I downloaded my stock rom from Sammobile.
No I flashed this via ODIN and rebooted and then did an update from Kies...This did not work to resolve the ISSUE of No Sound for me! What I had to do to fix this was to do a "Firmware Upgrade and Initialization" in Kies! What this does is ask you for your MODEL# and SERIAL# under your BATTERY. This then gets the firmware specifically for your device from Samsung. This updated my phone to 4.4.2 and everything works better then when I originally got my phone.
Again their are other threads that lay most of this stuff out but the last tweak I did not read and tried out of desperation. I hope this helps at least one person. I will continue to try and root my device because I am crazy like that. I have been an XDA user for 8 years now and enjoy custom ROMS on every android device I have come across. I cracked this S4's screen a month ago and they said warranty was void so to hell with Stock **** lol
I thank the XDA community with all my heart for giving me restless nights of modding fun. I have learned a lot from all of you and appreciate your time.
Hello XDA community
Iam a longtime lurker here what a great community with a wealth of information.
I have a a grasp of the basic rooting and flashing custom roms/kernels over the past few years on my old galaxy s3.
My partner had an OTA update for her gt9505 galaxy s4 today whicg seemed to hang while updating, unfortunately she pulled the battery mid update
The phone can enter download odin mode but i cant get it to open the recovery. I have flashed (using odin) a few different compatible roms they finish installing via odin but when the phone restarts it just turns off it will not go past the galaxy white and black screen. It will turn off again.
It has never been rooted, i spent many hours trying to get to the OS but it fails when restarting. I decided to flash CF-Auto root hoping to get access to recovery. Again it successfully installs cf auto root and restarts and then turns off.
It seems everything i flash never ever saves to memory.
What else can i try please? iam happy installing a custom rom but i cant get it working. iam afraid its bricked for good without expensive repairs.
thanks
lol i managed to get it working.
It was a combination of dead battery and multiple problem cables not charging the phone.
Hey folks, hope I`m not coming off as one of the "hey, I broke my stuff, how can I fix it without anyone knowing I broke it" types LOL. I`ve actually been modding Android devices since my Droid X what seems like ages ago, and have done a few along the way so it`s not new in theory. So....I`ve got an I337 S4. It appeared with 4.4.4 on it, and you can imagine how that went when I started modding. My ultimate goal was/is simply to have the native tether app working (and it was, very briefly). Long story short, I bricked it, and brought it back with 4.3 on Odin. It functions fine with the exception of Wifi. It won`t activate wifi, a very, very common problem I`m reading. I`m totally comfortable doing the mods to get it going, I just don`t know what I need. It`s rooted. (here`s where I`m lost): Baseband version is FNJ4, bootloader is FNJ4, but the BUILD number is MK2. Tried the BypassLKM method, no dice. So my question is this: What is the simplest way to get WiFi access back so I can get the Native Tether function going again? If everything was FNJ4 or MK2 I`d be able to make something happen, but several approaches have gotten me bootlooped and I`1m just ready to get it right (safestrap has saved my a$$).
Thanks for any help!!
update
See, a studious and persistent student of modding gets the worm LOL. I got my WiFi back with this procedure right here http://forum.xda-developers.com/galaxy-s4-att/general/how-to-root-i337ucufni1-t2881298
I used the safestrap method without a hitch. Hope it helps someone else out there
