[Q] Stuck at boot logo with stock rom

Good evening,
I currently have AOKP d2att 4.1.2 and I'm trying to flash my phone with the stock ROM from Bell using the following link (http://forum.xda-developers.com/showthread.php?t=1739426)
For about a month I was able to revert back to my stock ROM without any problem but this week I tried a couple of times to flash it but when it comes to reboot the device I'm stuck at the Samsung (animated logo) screen and that doesn't seem to go through.
Would that be because of the number of flash that I've done on my phone and it's blocking me from restoring it?
Thanks!
Boot into recovery and do a factory reset. Wipe cash data and dalvik. Reboot and should be fine.

I already done that but I'm flashing the stock ROM from Odin (FYI)
Did you do the factory reset after flashing stock ROM?

reflash rom
the rom isn't on the root of my device anymore and I can't exactly set it there without it turning on.
Causes a slight issue I imagine?

it doesnt have to be on the root of your device, as long as its in your storage. if its in the storage, find that location amd flash it. now what do you mean you cant exactly set it there without it turning on? you lost me there.
The rom isn't on my phone whatsoever.
I meant I need to be able to have the phone fully turned on in order to move the zip over to it.

what recovery are you using? twrp has an adb sideload option, cwm might have something similar.
Just push another nightly zip over with adb, while in recovery. Simple! Don't understand what the fuss is all about.

if u made a backup for ur stock rom, then restore it.
if not, the easiest way is to reflash factory image using fastboot mode. or see my thread in signature
Pardon my noobishness, but I really would rather not unroot my phone and set it back to stock 4.1.1 unless it's my only option.
Either way, I created a backup last night but it doesn't work. When I tell it to install it says "no file found".
At this point, I'm willing to let somebody take over via viewfinder if it'll help >_>
Flash new custom rom
And every modification SYSTEMUI.apk make sure permision each others

If u flash 4.1.1 i think u will receive update before rooting.

this is the thread you should have read BEFORE "bricking" your device. Which you didn't by the way. You don't want to know what a REAL brick is. Don't use the word lightly.
Sigh, one last question I guess -- even though I've asked a ton.
Now that I've flashed CM and my gapps, everything on the phone works except it shows that I have no installed apps...my messaging app, app tab..phone... nothing is there...

[Q] HELP! Nexus 7 (2nd Gen 2013) Does not boot any System/ROM!

I got my Nexus 7 (2nd Gen 2013) in the mail the 2nd day it came out from Futureshop and I loved it! I think its the best tablet in the world! :laugh: :good: Since all of my other Android Devices are rooted, I decided that it is a must to have a custom rom and root on my Nexus 7. So today, I rooted it and all went well, but when I wanted to download the Custom ROM Paranoid Android, it downloaded, it booted up, but then when it asked to select my language, I selected English then all of a sudden, it said "Unfortunately, Settings has stopped." :crying: :crying: I was so scared then I tried again and again but nothing worked. So I never made a backup when I was supposed to. I was too excited that I FORGOT. Then I booted into Recovery Mode and wiped and went to factory settings. But when I rebooted, it wouldnt reboot into anything! :crying: :crying: All it did was show a black screen. I was scared! I tried everything! But luckily, I can still boot into recovery mode and fastboot! PLEASE HELP ME! :crying: :crying: I WANT TO USE MY NEXUS 7 SO BADLY!!

Did you factory reset, wipe system & cache before installing the ROM?
If the ROM file is still in your tablet storage then perform the 3 wipes. After that flash the ROM.

It's nothing to panic about. The factory image package was recently released so you can use that to return to stock with Fastboot if you want.

If you got no backup, then the only thing left is flash factory image. Root it up normally and do a backup. After that flash the ROM.

OMG HELP! Bootloop, download modes works, flashed with Kies and STILL bootlooping

I have the SGH-M919
I've rooted my phone and was running a GE rom
Everything was fine for MONTHS
Got in my car and plugged my AUX cable to my phone for music and the phone froze.
Force rebooted the phone and it started boot looping.
Rebooted to recovery (TWRP) and TRIED to wipe dalvik and cache and it FAILED, said it couldn't mount dalvik
Rebooted to recovery again and wiped all partitions and this time it worked so I proceeded to re-install GE rom, still bootlooping
Came home and tried to use ODIN to flash M919UVUAMDL and it failed.
Tried ODIN to flash M919UVUEMK2, also failed (sorry don't have the error messages right now)
Rebooted phone into download mode again and phone said there was an issue and to use Kies to recover
Installed Kies and started emergency recovery and that went through fine and the phone finished and STILLLLLLL BOOT LOOPS !!!!!!!!!!!
Copied the file that Kies downloaded (M919UVUFNB4) and tried ODIN again to flash that and it flashes fine but STILLL BOOT LOOPS
Obviously my Knox warranty flag is tripped and I don't have the money for the insurance right now.... so PLEASE FOR THE LOVE OF BOB does anyone have any other diagnostic tips or tricks to help me figure out why the F this phone is boot looping.
53 views and no replies.... come on people... someone HAS to have something that might help..
Anyone know if ANY possible way to reset the knox warranty void flag ?

Only Samsung can reset your Knox flag. You can't expect instant responses here. People read and answer the questions they know how to. Not doing a full wipe before installing a different ROM often causes soft bricks and bootloops. I would start there although that doesn't explain why you couldn't mount Dalvik. Try a different recovery. Many people have had trouble with TWRP. Philz Touch works well if you haven't already tried it.

1. Samsung WON'T reset my flag... they won't even TOUCH the phone in any way shape or form. I spent almost two hours dealing with them and being honest about the situation. And they STILL won't do anything at all. The rep I was speaking too even said the first thing they do is check that flag and if its popped, they put it back in the box and send it back with no further action. So I will not buy form Samsung ever again.
2. I'm not expecting instant responses at all and nothing I said should have been interpreted at such. I made the comment of 53 views in 4 hours and not a single reply ... I was hoping for a better ratio of responses than that.
3. Where are you getting "Not doing a full wipe before installed a different ROM..." I never said that I didn't... and if you read what I took the time to organize neatly, I specifically state that full wipe was what I tried BEFORE re-installing the SAME rom.
4. Can't try a different recovery if I can't even get the stock factory image to do an initial boot.

Sooooo umm what ?
Anyway... I flashed PhilZ on my phone, did full wipe, tried installing the same GE rom I was using... didn't work.
Tried installing stock rom, didn't work.
Tried flashing M919UVUFNB4 via ODIN... and it flashes fine but again, first boot wont work.
Ok so .... I guess installing PhilZ... then full wipe, then flashing M919UVUFNB4 TWICE back to back did the trick.... no freaking clue how but it worked
I spoke too soon. Went through first boot. Got all the way to the end setup and then it rebooted on its own ... and now its stuck in a boot loop again

Since your using philz, choose install new ROM, then go to advanced and wipe dalvik, THEN go to mounts and select the one close to the bottom, wipe SD/data or something..... This will wipe your internal SD, OK so then install your rom and reboot.....
I am starting to think you flashed a non GE kernel and didnt realize it You just got to give the phone some love, thats all. It knows when your upset you know.

The weirdness continues
sooo it started boot looping again. Then I rebooted to recovery (which obviously after flashing NB4, its no longer PhilZ) and did factory reset. Now its working again with latest firmware.
Also I flashed the GE rom from HERE in XDA and used it for like 2 or 3 months then it suddenly stopped working so I don't think the kernal was the issue... I'm so freaking confused

Flash something else, GE is boring, Flash something crazy like Slim or something, that might work... Possibly it could be a bootloader issue, did you ever get on the MK2? Maybe you got one of the female phones. Sammy made some by mistake. they can be real finicky every now and then, like they work just fine most of the time, but about once a month or so they just crap out. Could be that too.

Well whatever happened it seems stable again now currently on stock NB4
Next thing to check is if the knox warranty flag is still tripped... Do you know how to do that ?

Philz's and TWRP both had small glitches on the GS4 4.2.2 Stock Rom.
I downloaded and installed the OUDHS-Recovery-jfltetmo-1.0.3.3.tar and have it all PERFECT now! You can search using exactly that filename and download it for your use. IT IS THE flashable Recovery Version.
I can, using Rom Manager, NAME THE BACKUP before booting into recovery, and it makes the backup just as I named it!
I can also recover using Rom Manager, and visually select what backup file I want to restore to, again, before booting into recovery!
CWM type backups take longer then TWRP backups to complete, but I have not had any instance that a backup I made couldn't be restored.
I did have that problem using "TWRP" and "On Line Backup". (No longer do I trust using those)
Hope this info helps your decision!
Good Luck and Aloha!
