Trying to flash a rom causes bootloop. How can I fix this? - Galaxy Note 3 Q&A, Help & Troubleshooting

I've got the note 3 for Sprint, and I already rooted it a long time ago. I recently got rom manager and backed up my apps, downloaded cyanogen mod 11, then tried to install it. Once I do this it gets stuck in bootloop. Any ideas? IIRC I rooted with odin. It was a long time ago, though.

Did you get the good ROM. They are now separate.... Have you done full wipe

I haven't done a full wipe, and I got the download from cyanogen mod's site, specifically the one for the note 3.

[Q] Doesn't boot

Hello,
I've got a problem with my gt-i9505.
I've managed to root the phone and install TWRP.
So i decided to install CM10.2 (21-08) and the right gapps for it.
Everything worked very good and I couldn't be happier.
All my apps were back and it was ready to use it!
I turned off the phone and went to sleep.
The next day i turned it on and it got stuck on the bootscreen (not the CM bootscreen, but the SAMSUNG GALAXY S4 bootscreen).
So I tried to do factory reset and install rom again, gapps again, afterwards again wipe dalvik and cache.
But i keep having the same problem. Right now after flashing the rom it doesn't even boot up the first time.
I also tried going back to 10.1, but same problem.
I don't know what to do, i just got my s4. Really hope i can fix it.
Luckily i can enter the recovery. But i didn't do a backup or anything.
Does anyone have any tips on how to get it working again?

Hi,
Look HERE
Put everything back to stock then, try again.
I found some 10.2 ROMS do not like rebooting,and just hang.
Remove the battery and try again normally worked.

I followed the instructions and succesfully installed the official stock rom for my device and region.
But it's still stuck at the samsung boot screen.
And now i can't boot into TWRP anymore either, is that correct?
After that I flashed with the .pit file. But still stuck on bootscreen.
Is there any other way to solve this problem?
idgaf about custom roms or CM10.2 anymore, i just want my phone to work.
Wether it's with custom or with stock firmware.
Really hope I didn't break my phone. :crying:
EDIT:
I wiped cache after flashing, but no data wipe/factory reset. That did the trick.
God i can't be happier my phone finally works again. Now i'm scared to flash a custom rom again. I think i need to install TWRP or CWM again too I'll just wait for now.

[Q] SGH-I337M Stuck on Boot Screen

I really hope someone here can help me. I'm running an SGH-1337M (Rogers). I rooted the device a number of months ago with Motochopper and installed Foxhound ROM GT-i9505 (which every guide says works with the SGH-1337M). I've been running this rom for quite a while without issues. Yesterday I I installed Cyanogenmod (cm-10.2-20131102-SNAPSHOT-M1-jfltecan) which worked, until I rebooted the device. When I reboot the phone gets stuck on the Samsung Galaxy S4 boot logo. I've booted into TWRP and tried to reinstall the Foxhound rom which was working but end up with the same results. I've used Kies Firmware upgrade to try and set everything back to default without sucess. Using Odin I tried to reinstall a factory image of my phone, which is sucessfull except nothing changes.
Currently, if using TWRP I do a full wipe of my phone and then install Cyanogenmod it'll work, so long as I don't reboot. If I reboot I need to do a full wipe, reinstall the rom and start all over.
I'm at a complete loss here. I've spent the last 5 hours looking for a solution to this problem without success. Any help is greatly appriciated.
Thanks

After you did odin, you must do a factory reset. This should clear up the problem. And, are you using the correct kernel for cyan?

[Q] AT&T s4 refuses to go KitKat

Hey XDA, just a long time stalker who has finally given up trying to find his solution on already posted items (I think 10 hours of trail and error means I'm not gonna catch what I'm failing to see...)
When I first got my galaxy s4 I downloaded KangaBean and it was on 4.2.2 I believe. Today I decided I should upgrade to 4.4.2 since I've only been hearing good things about it, and I wanted the slight updates that came with it.
Well, I have a AT&T s4, sgh-i337 that was on CWM 6 when I tried updating to another ROM, the first one I tried was GOOGLE EDITION 4.4.2 BY DANVDH. Did a wipe, cache, dalvik, format system, flashed it, flashed loki doki, said no to re-root/root fix prompt that followed, then I came to the yellow triangle, I thought that was odd, believed I missed something.
So, I downloaded TWRP 2.5.0.2 like the thread suggested, tried again, no luck. Then I tried Unoffical Carbon KitKat, which just caused the "Samsung Custom" logo to stay on indefinitely (I let it sit for 40 minutes before giving up.) After 2 failed ROMs, I tried KangaKat, updated version of KangaBean, so it should be just dandy right? Narp, same luck. This one boots, then reboots into recovery.
At this point I considered myself to be stupid in some way so obvious that I would die before I noticed it. So, then I just flashed the stock firmware thats like 2.5 gb through odin, re-rooted and installed CWM 6.0.4.4 LOKI'd and tried to flash KangaKat, being confident it would work this time, again I got boot to the logo and then reboot into recovery.
At this point I attempted the other 2 ROMs again, multiple times.
After some sobbing, I re-did the stock firmware, tried again, failed again.
My sadness turned into rage, I just destroyed one of my micro sd to usb-s because it was being annoying and I was annoyed, I took a picture and got over it.
I tried a 3rd time with the re-flashing stock firmware and tried with twrp again, no cigar.
Now, after MANY hours and MANY false hopes... I shall be using my blackberry and hoping to return to android soon, if somebody can help me figure out what I'm missing. Many thanks ahead!
Did you do lokidoki after?

Did you doa hard reboot clear the cache and davlik after it got stuck on the lock screen ? It seems odd that it would just not boot up at all. I was about to wonder if maybe it was the CM kernel bug that will keep it from booting past the initial screen but you tried aGE rom so...

Soft brick - Need some guidance

It's been awhile since I changed anything on this phone, I've been running CM11 with no issues. The wife was playing with my phone which is on cm12 and wanted me to upgrade it. Great, I hate having to touch her phone but ok.
1. Did a straight upgrade to CM12 nightly (couple nights ago build) with gapps from CM site. After the install everything crashes on the initial load, it's like the baseband is jacked and doesn't know how to handle the new google play services because everything crashes.
2. Went back and wiped internal everything this time, re installed nightly and gapps. No change.
3. Tried step 2 a couple more times and different gapps from PA and other random sites (micro, light, stock versions) and then TWRP just died on me. It's asking for a password when I first go in so now I'm stuck there. Tried to use ODIN to install the latest TWRP after converting it with another script found here (i'll find the link).
so, I'm probably going to have to use ODIN to restore some stock version of S4 ATT but I really don't know which one is stock that would work with CM12. I don't want to get caught in the safestrap crap of dual boot and whatever else. Any help is greatly appreciated.
You'll need to Odin the mdl firmware in Odin. Be careful as it will want to update itself after you flash it. See sammobile.com for the firmware.

Awesome, thanks!
Flashed the stock, towelroot, twrp from google play and cm12 nightly. Perfect and back where I left off. Thanks!!
Ok.. I did a bad thing I guess. after working for a couple weeks I tried to reset the phone while cm12.1 was installed. All it did was keep restarting TWRP and was stuck there. So I figured there was an issue with the twrp install or something whatever, I went to flash back to stock mdl in odin. Instead of selecting PDA I selected Phone and it failed on the first attempt. Then I selected PDA and it installed correctly (Said passed). Now I'm stuck on the AT&T logo on boot. I tried to reinstall the stock rom again and the same results. Where do I go from here??!?

Boot into the stock recovery and do a factory reset

Ok, factory reset worked on the second try. Sent it in to a boot loop on the first go around, odd. Thanks!

Galaxy Note 3 Bootloop

Good morning,
I'm stuck with a big problem on my Note 3 HLTE.
Here's the story : I was previously on the PAC Rom 5.1 and I wanted to change to get the CM13.0 that was just released. So I've performed the full wipe (dalvik, cache and factory reset) and then when I wanted to update the OS, it didn't work. I ended up with a phone in recovery, telling me that there was no OS installed on it.
after several attempts, I then tried to revert back to a stock ROM based on 4.4.2 with Odin. The installation went on without any problems, I was able to get through the first install with my Gmail account and then the phone rebooted, and that's where I got the bootloop curse.
what I did then, was to redo an install via Odin with my carrier stock rom, and I got a FAIL message. So, I retried an install with Odin by adding a PIT file and another ROM still based on 4.4.2. the install worked, as I was able to set up my Gmail account and so on. At this stage, I wasn't able able to get any signal for calls, 4G . In parameters, the baseband was identified as "Unknown". Then, the phone rebooted again, and I got the bootloop curse again...
My last attempt has been to install my carrier stock ROM after performing a full wipe, with ODIN. The install was successful and I got the phone rebooted to stuck on bootloop.
So, here's where I am, and I would like to solve this problem, please. What I think is that, due to the fact that I was on Lollipop, the bootloop might be due to the downgrade attempt to KK. So if there's any way to solve this problem, I'm eager to take it.
Thank you !
Hey Guys,
I've been able to resolve my bootloop problem.
I've installed TWRP with Odin, made a full wipe including data (I've saved them before), and I installed the CM12.1 by Temasek, and way to go, the phone is running fine ^^
Now, I'm just stuck with the lost IMEI thing and baseband. SO my question now is : if I want to install my operator stock ROM for getting back, should I just choose the Lollipop ROM, or can I take the KK one without getting stuck in bootloop again ?
Thank you !
