Okay I did this I got a pass but now the phone boots to the black screen with SAMSUNG in white on the screen and then the blue swirly thing then the white and yellow sprint logo and then back to the black screen with SAMSUNG in white and that's it. Either that or download mode.

Try booting to recovery now to wipe cache and factory reset. Power+home+volume up.

Sounds like you corrupted the partitions flashing all those bootloaders. There is really no random problems that pop up which can be solved by flashing bootloaders. You only need those if you specifically mess up your bootloader, or you need to update it. But you have successfully messed it up beyond my talent. If flashing the stock nj2 .tar in odin didn't fix it, you may need to use a debrick image. But I've never gotten myself in a position to need that so maybe someone else ca n chime in here.

Edit: I see you were trying to flash bootchains and root images all intended for the Verizon s3. That is a different phone than the sprint s3. You are going to have quite a time trying to undo that mess up. If its even possible.

That in a nutshell is what I have done to my phone. I can boot into recovery and download mode but nothing I have tried will work.
I'm ready to try using an SD flash. I was using an MK rooted stock rom 4.1.2 before all this happened. If someone can tell me how to make an SD image that that would work in windows I would appreciate it. Although I would need the android files on the card because I can already get to Download and Recovery mode. I'm at my Witt's end here. Please let me know if you have something to help me!

The phone has a 16 GB capacity, not a 16 GB rom.

Class 10 is just a speed rating, installs are not time critical.

To unbrick they are. Turns out only a class 10 is a go to unbrick. Don't ask me how I know.

I have no idea what you're asking or even what you're trying to say. If you can edit your post into the form of a comprehendable question you may get more response

The post you replied to has some broken quoted text from another thread, now merged....hence the confusion

Edit: fixed his post and quoted text

Edit again: fixed your post to include his quoted text so the thread flows better after the merge.
Yeah, I know, I'm confusing, but trust me...it's better now

This is what appears to be what I have done to my phone. I can boot to recovery and download mode but nothing I have tried so far has gotten me past that. {Another thing that bothers me is trying to get win7 to load the correct drivers for my phone. I've even tried turning off my internet connection but it still doesn't seem to install right except in kies or oden.} I tried to flash an SD card with a debrick image:http://forum.xda-developers.com/showthread.php?t=2660566 but nothing happened. I have the unified android skipsoft toolbox on my pc but I can't get win7 to install the correct drivers for the phone to use it! If someone can help I sure would appreciate it. The phone was rooted with a stock rom MK 4.1.2. I rooted it with Kies a couple of years ago. It's a Sprint SPH-L710 16GB I can't get the serial # because it won't boot to let me get it. I don't have the box.

Maybe I missed it but, have you tried the firmware flash from Sammobile?

yes that was the last thing I did. That's the one where you put it on the SD card, right? the one thing that I can't understand is if it boots to recovery and download mode why I can't go back and fix the 4.1.2 that's on there unless the thing that Madbat said is true, and I corrupted the partition. Oh and I still would like some help on getting the phone drivers to work in win7
Thanks!

No, you download it to your computer and flash it via ODIN....
http://www.sammobile.com/firmwares/download/29314/L710VPUDND8_L710SPRDND8_SPR/

Instructions

• Extract (unzip) the firmware file
• Download Odin v3.10.6
• Extract Odin ZIP file
• Open Odin v.3.10.6
• Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
• Connect phone and wait until you get a blue sign in Odin
• Add the firmware file to AP / PDA
• Make sure re-partition is NOT ticked
• Click the start button, sit back and wait few minutes

has nothing to do with the sd card

Does ODIN recognize your device?
As far as drivers, let me see what I can find

 

[congaman59]

Okay I tried it again. It passed in Odin but when it reboots the phone It goes from the White SAMSUNG to the blue swirly to the Sprint screen & back to the white SAMSUNG on black background and that is it. Oh and the blue led blinks up and down.

I am ashamed of myselp. no one told me you had to have the external SD card in for it to BOOT!!!! LOL . Well much thanks to you and everyone else who helped. My phone is booting and is upgrading as I type!!
