SM-910U Bootloop after rooting - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi all,
Thanks in advance for your help on this.. I've been trying things for the past few hours to no avail..
I have a 910U from Hong Kong. It didn't officially receive the 5.1.1 update yet, so I flashed a stock New Zealand 5.1.1 ROM a few weeks ago. I stupidly tried to CF root today without realizing that it doesn't work with the 5.1.1 version.
My phone is now stuck in bootloop. It goes past the first boot screen and reboots after the second animated screen. I tried to flash the stock 5.0.1 Hong Kong rom but I'm getting a NAND write start then FAIL in Odin. Same result with the NZ version. Phone has been data wiped, cache wiped, dalvik wiped.
I have TWRP on the phone but I'm not sure what else to try at this point.
I can boot into download mode and TWRP.
Thanks!

Try to boot into TWRP and flash a custom rom.
After flash back the 5.1.1 rom if you can

I've been trying to push a ROM on to the internal storage via ADB since I don't have an external SD card. However, I didn't have debugging enabled prior to my bootloop and I can't seem to get my device to show online through fastboot.
I'll try to get an external SD but at the moment I'm unable to flash a ROM through TWRP because I don't have one on the internal storage.

If you try to go into mount and enable MTP it will not work for internal ?
Because mine sometime mount both sdcard & internal memory so try with this tip ?

Blackscreen and boot to twrp

I have an international I9505. Stock rom rooted with cf auto-root and twrp 2.5.
I have been using it since I first got it at launch date. Just a while ago, I took out my microsd card without unmounting it first. I restarted my phone. Now, whenever I try to turn on my phone, it will show the Samsung S4 logo and then stuck at black screen. After that it will auto bootup again but to twrp recovery. I can't seem to boot it normally.
Any solution that I can do right now? Other than flashing it with original stock rom.

First just try doing an advanced wipe with cache and dalvik cache checked.
If that doesn't work I'm just letting you know if you flash the stock firmware via odin you will not lose any data, just root and you can easily re-root your phone.

Did you use the latest version of ODIN to flash the CF Root?
Think Odin3 v3.10.6 is the latest current version
If you used an old version, try flashing it again using the new one, other than that, I can only suggest trying to fix permissions in recovery if it has that option, TWRP should have it, and finally a factory reset, which is not ideal

i used Odin3-v3.07
but after flashing the root everything worked installed superSU and updated it and its binaries and installed busybox,.
it all stopped working after i went into Stock Recovery and back
id prefer not to do a factory reset Wipe,. unless i really have to to fix it ,.
im going to try reflash with the latest version then,.
i have swapped SD card to galaxy tab to put the Flashable touch recovery on the SD card, and swapped back to the phone so i could Flash the Recovery when im in stock ,.
but ill try flashing Root with latest Odin first.. thank you

the new odin is a bit less informative (to me as beginner)
i managed to use AP to flash the root again
all goes fine , it reboots
and its now upgrading android as it says and opening app's
then Black screen again,. i klick a button,. and it shows me again all the STOPPED msg's of all internal apps that are crashing,. litterally all apps,
what can i do ?
If clearing cache didn't work, fixing permissions in recovery didn't work, only thing left I can think of is factory reset

i cant fix persmission in stock recovery and flashing the philz touch recovery didnt work something about not verify signature,.
al i can do i guess is wipe data factory reset ,.but im affraid it wont fix anything
Try TWRP recovery instead
http://teamw.in/project/twrp2/229
No reason a factory reset won't fix things, worst comes to worst, flash the whole ROM again from ODIN, that will fix everything as it wipes and reinstalls the lot
Grab a stock ROM from sammobile
Thank you for all your replys mate..
I managed to get it working again by doing a factory reset in stock recovery after I flashed root with latest odin
Even tho it was my last resort there was nothing else I guess .
I'm not sure tho if this will happen again when I go back to recovery like I did when this all happend the first time while I actually want to flash a more advanced recovery then stock recovery ..
But I'll take my chances and just leave it as it is
Again thank you for your help and suggestions .

Pleased you got it working again, I would say if you think you might want to flash another advanced recovery in the future, it might be best to do that now since you have already factory reset the phone, that way if this happens again, you don't lose months of data and settings and files that you have gathered between now and whenever you decide to flash recovery

i have actually ,. i installed the TWRP u mentioned,. by taking there app from the Playstore,. and flashed the new recovery, within android and without rebooting (just in case)
im used to the old CWM thats why i first wanted the Touch recovery as its based on it,
but always open for trying new things
Thank you
Good stuff
Id say the whole entering recovery / apps crashing thing was a problem with the ODIN version you used to root, too old for Lollipop is my guess, so I wouldn't worry about entering recovery again.

[Q] CWM disapeared, boot loop, only have access to android system recovery

Hi guys
(SM-N9005)
So yesterday I had liquid smooth rom installed for the past month or so (I have been trying a variety of roms for the last year or so) and I was getting some bugs occuring and decided to put a new rom on.
I booted into recovery, did the normal backup, factory restore, clear cache and dalvik, installed the rom and restarted my phone. It then went into a boot loop.
At this point I assumed it was no biggy, so I just went back to recovery and chose to restore with the backup... except it wouldnt. it couldnt recognise the file it had just made.
So I then coppied some previous backups to the external micro sd, stuck the micro sd card in, booted in recovery and tried to recover with them... couldnt recognise them.
I also noticed that when trying to reboot, it came up saying that I didn't have root access... even though I certainly have for the past year.
I tried flashing an updated version of superuser as that was the suggested method on some forum - didnt help the situation.
Now when my phone boot loops, it goes straight to android system recovery <3e> and nolonger have access to CWM
No idea what to do, and my uni work greatly depends on me having access to my phone :/
Any help would be greatly appreciated
my baseband version is LRX21V.N9005XXUGBOB6
i got some problem ... it freak me oute but i founnd how to back my stock firmware backk
you shoud find your firmware ... it can be downloaded from sammobile.
and flash tar.md5 file via ONDIN.
good luck!

[Q] Bootloop official OTA

I found a previous post that somebody is posting out and saying that they had the same problem for india devices.
I did an update from system ota and i got stucked in the bootloop, but it could proceed until Optimizing apps screen.
When the optimizing reach 2xx of 302 then it will reboot, after many tries of rebooting my phone, it is still stuck at the same place.
What should i do? I just went back from Hong Kong and all the photos are inside. I want to recover them.
Model- N910C Malaysia
Issues : Update from offical OTA lollipop
Tried:
-Wipe cache
-Reflash the same stock rom by using odin without wiping the data (from sammobile)
-Flashed back to the previous version of android (4.4.4)
-External SD card updating
-Did tried to apply adb update or pull the contents of the phone by selecting "apply update from adb", but i receive error from the adb.exe everytime i want to pull.

Bootloop on Lollipop Stock

So, yesterday i tried to install Euphoria OS on my phone, but in all of a sudden, the /cache partition corrupted, i was dumb enough and deleted it via TWRP, making my phone fall into the QPST status.
After fixing it, i proceeded and reflashed KitKat, but the phone only shows 8GB instead of 16GB, so i tried to fix this by flashing TWRP, everything went well, until i upgraded to Lollipop again.
It always bootloops no matter what i do, i really need my phone with my 16GB of storage back, it isn't a Hardware failure since the QPST diagnosis didn't say anything about mobo failures.
I can mount all the partitions, i can wipe it all, i can boot into bootloader and recovery, i can do basically everything but booting the system.
Any light on this? it either happens after i flash TWRP or after i try to root it.
Im running Android 5.1.1 stock.
List of tutorials i have tried (In order): http://forum.xda-developers.com/nexus-4/general/wip-unbricking-nexus-4-using-qpst-t2208289

Don't you dare tell me to reflash the ROM again, this is the first thing i have done, i did this 20 times already and it never worked. It isn't a ROM problem. It is a partition problem somewhere.
Fixed, had to use LGNPST to reflash JB 4.4.2, then upgraded to a ZIP version of the Lollipop ROM, then flashed the stock one.
I'm having the same problem with my Nexus 4. I read also about LGNPST, but I remember something about flashing the Optimus G cache partition I believe, then manipulating one of the prop files afterwards in order to get your 16gigs back. The problem is that all of the files needed to do this flash are attached to a stupid downloader site and so its full of pop up windows and adware from what I've seen. I can't get mine to boot into system, or bootloader, or recovery, etc. The device will not finish looping for debugging to be enabled, and even trying to boot into download mode is not happening. I've tried all I know to do, especially considering fastboot and adb both utilizeusb debugging. I really am baffled. Any root kits I've tried also don't work so far. Help please.
