[Q] Note 3 MJ5 Bootloop, what do i do? - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

I was experiencing problems with my rooted mj5 so i used that popular thread on how to revert to stock mj5. Everything went smooth, but im still having the bootloop problems. The custom lock logo is gone on bootup so i know its true stock mj5 now, but my loader hangs on the ATT animation logo for a bit then keeps restarting. This process goes on and off for a few times until it manages to pull itself through. Should i call ATT for a replacement or is this fixable?

Went into recovery mode and cleared cach - didnt work
Went into recovery mode and did a factory reset - didnt work
f*ck.

Did you flash the 2400258.zip file in the stock recovery?

This. I've reverted back to mj5 multiple times and never got into a bootloop. Don't take it back to AT&T for your mess up. That's fraud.

As i stated above the factory reset does not work. I noticed the main problem was coming from the sd card slot. It doesnt matter what sd card is in there, it will cause the phone to lose signal and enter a weird bootloop. A few hours ago i re installed mj5 and did every step to get a 100% new stock again. The 16gb and 32gb class 10 sd card will cause my phone problems. The main problems are bootloops and if i go to make a call, the service bar will turn to an O with a slash until i end the call so i can not call anyone while my sd card is installed.

Im considering just updating to kitkat and if it has problems from there then i know the phone has hardware issues, then off to AT&T it goes...

Need more info..are you just trying to get rid of padlock or is phone stuck on thst screen? If so did you try battery pull or booting into recovery via power button + home+volume up

You don't need to be on MJ5 to restore to it.

Both. I have the padlock and it stays on the Samsung screen. At this point I just what to get back to a stock state and clear any of the tamper flags

I had a similar problem yesterday. I accidentally deleted my os without replacing it cuz im a noob. I was stuck on the boot screen with the padlock.
I went into panic mode and upgraded to kitkat. It worked, but I wanted root, and safestrap. So I followed the method that you linked, and it successfully restored me to 4.3 with root access.
In short, it will work, but it will wipe your phone. And it didn't trip knox for me.

Problem with brand new Note 3 and safestrap

Please I need some help! I just got a Note 3 today (I had a Note 3 when it first came out) and installed safestrap to it. I put a rom on my 64gb card and backed up the stock rom and then wiped all data, system, cache, etc. and when I tried to flash the rom it failed. I tried to do my restore and that failed also. I rebooted to recovery from safestrap and it went to the factory recovery. When I try to reboot the phone it just sits at the Samsung screen with the custom and lock icon. I don't know what to do. I think its the 64gb card that wouldn't allow the rom to be flashed or the restore to work. Is there an odin back to mj5? I think it's the only thing I can do.

I was able to restore to mj5. Do you know if there is a problem with 64gb sdhc 10 micro sd cards or flashing roms to the stock rom slot?
Flash from the internal. Report back

After a lot of playing around I think it is safer to use a 32GB for flashing or internal. Sometimes recovery doesn't play nice with a 64GB.
i would always recommend flashing from the internal with safestrap. just seems to be more stable. keep the file on your Ext for safe keeping but copy it to your internal for flashabilty<<<

Might get more help over in Q&A, but I would use the method here to return to stock mj5 and then ota update to nb4 then root and such from there.

I didn't have any problem with X-Note (which is now my daily ROM) or Dynamic, but I couldn't restore my stock backup - until I deleted the slot and made the data space larger. Check your sizes.
The only differance between the two phones is that my other note 3 has none of the at&t apps that they put on there. Maybe thats what the problem is . But the other one i had the stock rom and two other roms on it at one time and had no problem .

Odin to Stock

Long story short, I was trying to install Dynamic Kat but it wouldn't work. Each time I would try to install SS 3.72, it wouldn't boot into recovery. If I tried to flash the ROM with SS 3.70, the ROM wouldn't boot--it would just get stuck on a black screen with a blue LED. I was advised to flash Odin and start over. I've been trying to flash stock with several files, however nothing is working (N900AUCUBMI9_OneClickBin.exe). It fails everytime.
Anybody know what I can do to resolve this issue? Needless to say, my phone is soft-bricked at the moment.
Are you able to get into safe strap at all?
As in safe strap recovery.

Thank you for your response.
I actually got it resolved. I was on a ROM which I thought was 4.4.2, however it was 4.3 so it was causing a bunch of problems. All sorted out now
Glad you got it figured out.

No Os.

Ok so I had this att note 3 unused laying around.. So decided to root/twrp it using safestrap.. Well all was good went and got the du rom and gapps and went to back up my stock os with twrp but, took up about 7 minutes of my time to back it up so I thought all was good and did the full wipe.. Well the rom didn't work and for some reason my backup didn't save... So now I'm stuck with no os.. Would like to get back to factory os and I made sure I didn't do a wipe of the SD just the factory reset in twrp.. Any help would be great.. Haven't messed with a Samsung device in years...

If you follow this link, you will be able to download the odin files to get your phone back to NC2 or 4.4.2
Thanks for the quick reply, but I guess you have to go in trwp and manually select the internal SD card, I did and my backup was there so restored it and everything is OK!
