After I was presented with a system update about a week ago my nexus s entered a boot loop, not knowing why I tried to restart it a couple of types via removing the battery. That didn't work so I entered the Fastboot mode and tried to go into recovery but I couldn't do that because I was then presented with a exclamation mark like picture on my Nexus S, My phone was rooted before because I wanted to install Miui rom, then when I went back to stock rom and everything seemed to work fine, but when I tried to change my rom again it said I wasn't rooted but on my bootsceen it says I'm unlocked. I also did a permission test, from here I don't know what to do if anyone could help me I'd be very grateful.

Flash clockwork recovery, through fast boot.
restore or flash new rom
Sent from my Nexus S using XDA Premium App
Alrighty, I flashed Clockwork recovery, now thats left is to flash another rom.
I was using Kangabean ROM found in the development section for a few days but was unhappy with my wifi and data connectivity and was unable to solve it so I figured id try a new rom and see what happened. Well I downloaded and tried flashing Super nexus 3.0.
I'm a telus I337M and i thought I could flash this rom even though its ATT because of this thread, I flashed my stock kernel and then the rom, but when I went to flash the rom it failed instantly. So I than rebooted my phone and it hung on the bootscreen. I than wipe/factory reset and re-flashed kangabean rom and KTs kernal because i knew it worked. Everything flashed, I wiped cache/delvik after install but when i went to reboot TWRP said root is not detected....swipe to install superSU, but no matter what I do my phone restarts and always gets stuck at the boot screen.
I have access to TWRP and Download mode so I am currently downloading the stock rom and kernal. I also have my stock nandroid backup before i originally rooted and flashed a custom rom. Whats my best course of action to take? Do I flash the stock rom through odin than factory reset in recovery?
Thanks for any and all help in advance. I'm pretty "green" when it comes to this stuff so any help is appreciated
I'd use the nadroid backup first that way you don't have to worry about loading a recovery to the s4 or wait to download the firmware. If that doesn't work Odin stock.

Just to update you guys in case anyone else has my issue in the future. I tried restoring my stock nandroid, however when I went into twrp and tried to recover it but was unable to because it showed my sd card as empty.....I'm assuming because I somehow lost root access.
Unable to flash my nandroid I downloaded the telus stock rom and flashed it via Odin. My phone is now functional again as we'll as re rooted. I restored my files via titanium backup but I noticed one big issue. My wifi doesn't work...I can access the Internet via my data plan but not wifi. Any idea as to how to fix this?
I also notice this telus stock rom has a lot more bloat than what my s4 originally had when purchased from the telus store. Not that that's as issue cuz I can disable it but I'm just curious as to why? On the notification bar there is also an N beside the wifi symbol with its own wifi looking symbol that was never there before.....what is this??
I appear to be bricked. I flashed a recovery via flashify. Phone gets stuck on fastboot. This is coming from Houstonn's excellent PA rom. Tried to go to recovery. Goes back to fastboot. It just shows udc start. Tried connecting to my PC to flash another recovery via fastboot and it's a no go. Just shows wating for fastboot. Booting doesnt work either. Bootloop. So I figured game over and I'll flash to stock. To my horror, the restore process stops at 49%. Apparently, you have to come from a stock based kernal for it to work. Am I bricked for good?
Hello you must flash a stock Rom in the download mode.
Sorry... I don't saw that the flash stops
Then you must install twrp and costumrome again

Thanks for trying to help. I got it fixed without losing data. I got it to boot into the rom after shutting it down for an hour. Apparently it was overheating thats why it didn't boot. But if for stuck at the starting apps screen. So used adb to flash recovery again. Booted into recovery and reflashed rom after clearing data. Running like a champ now.

Yesterday I was normally on the cm11 nightlies, and decided to go back to 4.2.2 stock tmobile, just to update to kk . I loaded my stock backup, and all went fine. It downloaded an update, did not say what just system update and after that it restarted to twrp recovery. Tried rebooting to system, but all it does is boot back to twrp. What I saw is that it reverted back from 2.6.4 to 2.6.3 version. Flashed the 2.6.4 version from my folder, and the same happens. Tried restoring my backups, taking long but to no avail. Right now I have a bootloop to twrp and don't know what to do. My computer doesn't even recognize phone. Not even usb otg shows up.

There are threads in this very section that will explain what you have to do. Note, never take an ota with a custom recovery!

Hello,
Please help me out guys
I tried for the 1st time to flash custom recovery TWRP - it worked.
Then, i immediately entered to TWRP and i tried to root my phone installing the supersu.zip. When i rebooted my phone - bootloop
In the end, I reflashed stock rom via ODIN but my phone still gets bootloop at SAMSUNG LOGO(NEVER HAPPENED BEFORE)
PS:If i try to enter stock recovery - first it appears "installing system update", then "no command" and then it enters the stock recovery, but nothing can solve the bootloop problem
please help
1.Why bootloop after rooting with the supersu.zip?Should i use the cfautoroot metod?
2.Why bootloop after reflashing stock rom?Never happened before!!!
Thanks!

J500F....
I think i managed to solve this...I was flashing the 1st update package .tar which was released for the J5 last summer
Flashing that - not working NOW, ALTHOUGH it worked a few months ago
Flashing .tar from SAMFIRMWARE - working!
But what about the root problem? Which way is the proper way to root your J500F 6.0.1 without bootloops&stuff

Nothing works: supersu.zip, cf auto root.zip....
i only get bootloops
After flashing using TWRP you should always clear dalvik cache,
The first boot always take some time, 2-5 min,
Before flashing anything try to do a nandroid backup,
The supersu.zip method worked for me,
There is a detailed thread on xda j5 forum on how to upgrade/downgrade and root your device,
After using Odin to flash a ROM enter recovery and wipe data then wipe cache
Sent from my SM-J500H using XDA Labs
Update:
1. It seems it ONLY works to flash 6.0.1 AFTER flashing 5.1.1.(so i have to always repeat this double procedure)
Reflashing 6.0.1 over 6.0.1 - NOT WORKING
2. About root problem - damn, i still can't make it work. I will try your advices and let you know what happened,
Thanks!

I've seen your PM.
I don't really have any idea. But I have a suggestion, although I don't know if it will solve your problem. Backup your stuff from internal memory before. Try to wipe everything including internal memory (internalsd in TWRP recovery), then turn off your phone and re-flash stock rom.
Hello, @Lawr3nce I followed this tutorial by @rjrulz007 http://forum.xda-developers.com/galaxy-j5/how-to/tutorial-upgrade-j5-2015-to-6-0-t3443904 to root my j500h, I downloaded the supersu.zip from this link http://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703
Don't forget to backup your data before upgrading (you can use smart switch), after flashing using Odin go to recovery (stock recovery), wipe data/factory reset and wipe cache partition, this should solve the boot loop problem.
Before flashing the supersu zip file do a nandroid backup using TWRP (boot to TRRP, choose backup, select sdcard as save location then swipe to start backup. In case the flash of zip file failed choose restore and select the backup you did before, better than reflashing the whole ROM using Odin )

Ok, thank you all for the help. Conclusions:
1. For some reason, it NEVER works to flash directly the 6.0.1...I always have to flash the 5.1.1 first, then the 6.0.1.
2. I will try that root procedure from the link .
I am very willing to root it because i want to remove many useless preinstalled bloatwares from my phone
(due to very low free space i can't even update my apps)
UPDATE: That procedure with that .zip WORKS! THANKS
