[Q] Strange root problem, please help

Okay it's been a few months since this has happened so I'll try to remember as best as I can; I had rooted my Nexus using WugFresh's kit, everything went fine. It was rooted for about 6 months and eventually got stuck in a boot loop (no clue how this happened, I hadn't installed any kernals, roms, even apps in months). I tried like 4 or 5 different methods to fix the issue; I finally was able to get the phone working again using ODIN mode, it completely restored it to stock (as far as I'm aware).
So I tried to re-root the phone; no luck, using ANY method I've been able to find. The main problem is I can't seem to get into TWRP, every time I try to it simply gives me the dead android with the red exclamation point. I'm not an advanced user by any means, but I'm not totally clueless and I can follow directions. If anyone has any advice for me on this I'd GREATLY appreciate it, I have an excellent 4G signal where I live and the only other internet option is AT&T basic DSL so I'd really like to be able to use my wifi hotspot again. Thanks in advance for your time, I appreciate anyone who takes the time to try to help.

1) android on its back is stock recovery.
2) follow this: http://forum.xda-developers.com/showthread.php?t=1529058
it works 100% of the time if you read and take your time.

it sounds like you have root but cant flash a recovery, let me know if im wrong but if this is the case I would just download goo manager from the market and go into settings and flash a custom recovery and that should fix your recovery problem but sometimes you have to download the recovery twice ive noticed that in the past, let me know if this works for you or you could go through the longer process above but your fix may be very simple

Thanks for the info, I will try this either tonight or tomorrow and get back to you; I certainly hope it works!

I thought that too, but I tried installing super user and a couple of other root-only apps and it said that my device wasn't rooted. =P

This is driving me insane. I'm trying this method; I followed the directions step by step, but my phone is showing that it is unlocked already (when I entered the fastboot oem unlock command in CP it returned FAILED: Invalid Command, but it is showing as unlocked in bootloader.
Now for the weird part; I rebooted to bootloader and tried fastboot flash recovery recovery-clockwork-6.0.2.3-toroplus.img and it returned immediately FAILED: Invalid Argument. I decided to start the process over, and now I can't reboot from CP, it's saying error: device not found.
I really want to just smash this f*%&ing thing into several hundred thousand pieces right about now, so I'm going to take a break for the moment. Are there different types of bootloaders, or is it possible the my bootloader is just corrupted or something?

There are different bootloaders, but the fastboot commands should work just the same. You're on Windows i'm assuming? You could also look at efrant's guide, http://forum.xda-developers.com/showthread.php?t=1626895, as well as his 101 in the general section stickies. It does not make sense that the device would become not found, and I would try reflashing the bootloader. Don't smash the phone!

Have you tried this method?

[Q] Attempted Factory Reset now locked out!

So this may be a stupid question (but it's my first post so go figure) but I've read a few forum posts and I still can't seem to find a resolution.
I'm using a Rogers SGH i3170 with Android 4.3. I used the cf auto root file to root my phone with ODIN and otherwise did not modify the original software I manually installed the SuperSu apk to get around KNOX.
I was going to sell the phone so I went into the backup & reset option to clear out all my information. the phone seemed to clear itself just fine but now it won't go back the 'samsung' boot screen.
It'll show the device name, do the boot animation and otherwise just sits there.
The battery is at 80-90%
My main issue is that I would flash the stock ROM but it also won't go into recovery mode. It just reboots without actually going there.
Did I just brick my phone?
**I'm fairly new to rooting, I've rooted my S4 and Nexus 5 and was able to reset them without issue through the menus without using CWM or TWRP. I'm familiar enough with the processes just need some direction I guess!

Try this: Vol down& power& home. That'll put you into download mode so you can use Odin to return to stock...
You can also try THIS
If that doesn't help then goHERE for more INFO:thumbup:

My guess would be depending on what options you chose for wiping your data you probably wiped the root folder.
in which case there is nothing to boot to.
I have done that before in error and its a pain.
If you still have a recovery great you just need to flash a ROM.
Otherwise you might have to ODIN a recovery back on and then flash. Which is what I had to do.

Pattern locked S3 need unlock/install cwm

long story short i have a Sprint galaxy s3 that is locked w a pattern lock and im unable to get in. i did ALOT of research and came across a few options but none work. one method says i should use adb to remove the lock ( http://forum.xda-developers.com/showthread.php?t=1800799) got stuck cause its not rooted and no custom recovery. i tried to flash CWM and root using this method (http://galaxys3root.com/galaxy-s3-r...gh-t999sgh-i747sph-l710-fail-proofnoob-proof/) odin said pass but i wasnt able to get into any custom recovery it would just hang when using the vol+ home power combination. stock recovery still works the same.
All i want to do is unlock this phone that has a pattern lock.Google account not an option.the owner passed away and im trying to unlock for her family to get contacts and internal photos etc. im not sure if usb debug is on however adb recognized the device so i assumed it was. the reason i guess im having a hard time is because not alot of information is available given the circumstances. Ive been reading for 7+ hours now afraid to ask for help as ppl always get flamed if there is already a solution somewhere. if there is i havent found it. Thanks for any help

Follow this to get custom recovery: http://forum.xda-developers.com/showthread.php?t=2011491
Then mount /data and delete /data/system/gesture.key from recovery

It probably does the same thing I just said, delete the data/system/gesture.key file

HELP!!! I tried to root my Note 4 SM-N910V and now it bootloops!

So I used this guide:
https://www.reddit.com/r/galaxynote4/comments/4f8cgc/guide_a_noobs_guide_to_permanent_rootunlocked/
When I got to step 8, the phone would freeze. Super Sume wasn't doing anything. Then the whole phone would freeze. I looked into what it was supposed to do, and I read that this step was just uninstalling the app due to spyware. I figured "I'll worry about that once I get root. Then I can install a whole new rom, and it won't be there regardless." So I moved onto the next step. I got all the way down to step 10, and the adb wouldn't connect. So, I went to reboot the phone, and it says "root is not available, would you like twrp to root?" or something like that. I said yes. Now the phone is in a boot loop. I don't know if I have root or not. I tried doing a factory reset, by wiping. That didn't work. Still boot looping. I know my device isn't lost, but I don't know what the next steps are to getting it back.
I'm also currently downloading http://www.sammobile.com/firmwares/download/65392/N910VVRU2BPA1_N910VVZW2BPA1_VZW/
this, in case I need to start all over with my phone.
Can anyone help me at least get past the bootloop sequence? It goes samsung galaxy screen, samsung animaltion, verizon red screen, then bootloop.

Did you format you're SD card?

Did you get it working??

I did. I followed that guide about 4 times, and each time I had to reflash to stock with odin. As all this was happening, on a second computer I was researching why it was bootlooping. Well, as it turns out, the guide is bad. The reason I was bootlooping is because 5.1.1 has a special security detection that if it detects root, it will bootloop. You need a different kernal, but his guide said to turn the phone back on after root but before flashing the new kernal.
So, eventually I just tried my own way. I got the bootloader unlocked, and then went into twrp, to flash the new kernal and supersu from zip. It worked.
As I type this, I'm backing up my real SD card (I used a smaller temporary one for the root process), because I'm going to format this, and only put my pictures/old apks/music on it. That should clear up 90% of the space. After I have it backed up, formatted, and files moved to the SD card I will be flashing my first rom.

Having problems rooting Verizon Note 4 after downgrade to Lollipop

I have tried to root my phone (Note 4 910V) several times but I continuously go into a boot loop that ends at the Verizon screen. It gets to the Verizon screen then it restarts. The only way I have been able to recover from it is to use Odin to reiinstall the system files again. Any assistance would be appreciated.
Thanks

If there is a root section please move the thread to Root Note 4 section

after again reading the guide on how to root I found the section I get stuck on....Its is
"8) Allow device to reboot. After full reboot, power down and pull battery." It does not full reboot it loops at the Verizon logo

Did you remove the micro SD card? If not you have to. Make sure you are using the right kernel.

I did remove the micro SD...OK..that's where I am losing it. What kernel should I be using and where can I learn more about Kernels?

Emotion kernel or multisystem kernel.

I had the same issue but I fixed it. After flashing thro ODIN you need to wipe and factory reset in recovery. Worked like a charm for me. Good luck

Wow....Thank you. After a factory reset it worked for me as well
