[Issue] Strange Reboot Loop - Nexus S Q&A, Help & Troubleshooting

My phone was working fine. No changes or mods recently. I unlocked it to check my messages and it went into a reboot loop. Not just a reboot...but a reboot loop. I had to take the battery out. This I am using CM7 Nightly 25 with Og kernel.

Did you try to flash your current rom again via cwm recovery?
Remove the battery from the phone. Put it on it then press vol up plus power button and hold. Choose recovery then try to flash cm7 zip file again without the custom kernel? Does it work?

What do you mean by unlocked it to check my messages ? Were you referring to SMS & screen lock ? Are you using a setCPU screen-off profile ? Generally such unexplained ghosts tend to disappear across a reboot. It simply could be because you are on a Nightly build which could still have bugs waiting to discovered. You may want to migrate to RC2 release of CM7 for better prosperity.

Workaround for ICS power/reboot freeze

Using Elixir and QuickBoot, you can create a widget in the notifications dropdown with working buttons for power off, reboot, and boot to recovery. The attached screenshot shows mine, which also has four Audio Manager profiles.
I'm using ICS SMOOTH ICE and don't seem to have any reboot or shutdown freezes when I use the options from the power menu. Can anyone else confirm this?
Or you can use switchpro and use the reboot button.
Flash cwm touch, then flash this kernel. This fixed shutdown and reboot for me. Or just hold the power button down for 10 seconds.

What does the expression "fully functional " mean? To me it would mean 100 % bug free, and we all know that is a pipe dream. Of course it could mean "everything works and I haven't found any bugs... yet." But that just means you haven't been using it enough, LOL!
I just got a kick out of the expression. The is a certain arrogance it conveys, though I am pretty sure that is unintentional - I think my Skyrocket will be "fully functional" when it can get up before me and make the coffee.
Freeze shutdown app in titanium. It works fine.

My new fix
After flashing too many ICS ROM's and mods, I had the restart/reboot freeze and my screen would not automatically turn off, no matter what the timeout setting. Here is how I fixed both:
wipe data/factory reset x3
wipe cache x3
wipe dalvik x3
Darkside wipe x3
flash Superlite 4.2 ROM
wipe data/factory reset
reboot
now, so far, all works - reboot works, screen off is back to normal, ICS goodness.
There shouldn't be any shutdown freezing issues

Yeah the dev fixed the problem in the ROM so that the shutdown actually worked instead of froze. On the v2 changelog it mentions the shutdown/reboot bug is fixed

Sky ICS 4.2F-4.5A stalls in reboot

Anyone one else experiencing a stall when rebooting using SKy ICS 4,2F-4.5A?
If I reboot either from CWM or from using the drop down or the power button, the phone hangs up with a black screen and all the LED buttons lit up? Then I have to hold the power button down to do a hard reboot.
I have reflashed numerous times and have come through numerous updates and this one issue persists.
Anyone?

No problem here. You have installed busy box, fixed permissions, and the usual stuff?
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2
I got the exact same issue, busy box installed, permissions fixed. Tried flashing everything again didn't solve it, kernel etc.
The only thing I didn't try is radio, are you using rogers radio as well?
Also it happens if I just try shut down the phone.
Try doing a backup in cwm, then just immediately restore that backup... often fixes that problem for me on sky ics.

I got it resolved but only by fluke. Flashed 4.2-5b as well as the CYMBALINE kernel (an attempt to resolve bluetooth connection issues) and now everything boots fine.
Thanks
I flashed the kernel without it being solved. I did the backup+restore and I think it seems to have fixed it, I'll do some more checking tomorrow kinda late here but thanks!
Btw after you flashed 4.5a you didn't need to flash b
Had the same problem after doing a fresh 4.2 R2 base install. I let the phone fully cache (5 mins or so) and I tried rebooting to CWM to flash the 5A update and the phone hung on shutdown and my cap lights stayed lit up. I realized I forgot to install busybox after 1st boot-up per the OP instructions. So I held power button for 10secs, rebooted, installed busybox and it rebooted fine into CWM to flash update. Weird, never seen that before.

Running Rogers ICS stock here rooted and busybox first, then flashed the modded UXCLF3 Kernel, hangs on the Rogers animation and the touch keys stay on whenever I try to shut down or reboot the phone, have to pull the battery all the time, trying the Backup + Restore route now, hope it works otherwise I'll have a brick and a phone that won't turn off

It worked for me, worst case you can hold the power key for 10s to turn it off.
The issue me and I think also the other guy had was black screen and touch key lights.

This has been answered in the dev thread. Here is the solution . You need to flash it with cwm touch. I have no idea why but with cwm the older cwm you get hung up rebooting or shutting down. It will also hang when fixing permissions. I have also read that twrp was working also.
Cwm touch can be found here half way down the thread.

Odd behavior when upgrading to cm10.0.0 on HTC one s

I just downloaded the newest CM release (10.0.0 stable) and upgraded. For some reason every time I attempt to boot up my phone it sends me directly into recovery (clockwork). Its almost like a boot loop, but I go into recovery instead. I've tried reflashing to an older nightly version of CM10 that I know works, but it consistently just sends me back to recovery when I go to reboot. I tried a Nandroid restore, same thing. I'm not new to flashing Roms, and went through all the rituals (wiping data/cache, etc). Never have had any trouble flashing Roms in this particular phone.
I can't get into fast boot either, always goes into recovery. Has anyone seen anything like this before? I'm running out of ideas of my own. Any ideas are appreciated. There's a beer in it for the best information leading to the reconstitution of this jobby.

Getting into fast boot is tricky...hold down arrow and push power, then release vol after boot.
Are you flashing boot.img properly in fastboot?
OK. I got it semi sorted out. It turns out there is a bug of some kind, I am not sure if it is special to the One S or what, but it is to mine. CWM gets thrown into a sort of boot loop if the device is charging while attempting to restart, and won't boot either into the rom nor into fastboot. It won't respond to adb either. It just keeps going into recovery. And it won't shut off. This happens when charging for some reason.
After I took the USB cable out I reset it with volume +, volume -, and power. I guess HTC put that little trick in there to simulate removing the battery since you can't take the battery out of the back. That effectively shut the phone off. Then I was able to get into fastboot and connect with adb. I put Team Win Recovery on there instead of CWM for now, and got into recovery. Wiped everything, and flashed the extra rom I had on there.
I am still unable to flash CM10 stable, it just goes into bootloop if I try, but at least I have my phone back. Hopefully I will be able to figure out if there is a way to kick start it on there, or whatever bug is solved. Look forward to trying it when its (or I'm) not broken.

The One S isn't offically supported by CWM. It sounds like you need to try and flash the boot.img in fastboot.
Try TWRP...it will be better

That's weird. CM10 comes up as an update...
Either way, I tried flashing the 11/11/2012 nightly through twrp and came up the same thing, would just bootloop and not go into the rom. Fortunately I could still access both recovery and fastboot, so I went back to a previous nightly from last week, and after a (painfully long/manual) titanium restore, I'm back to normal. I'll have to investigate what is going on later when I have some extra time to commit to it.

Yeah dc211 was right. I'm using hboot 1.14, had to go and flash boot.img in fastboot. Install went smoothly after that. Thanks for the input y'all.

Before you flash this you need to remove "qrngd" file from the rom . The file is located at system-bin-qrngd.
I was able to flash 10.0.0 without removing qrngd. So far it hasn't been a problem. I read somewhere that file is some sort of random number generator, but that it isn't clear whether its even used anymore. Also, they say its more of a problem with earlier nightlies, especially with people using HBOOT < 1.14. It might be just junk DNA in the system files, or they may have patched the problem. I will keep my eye on it though, and will report back if I get any spooky behavior.

That was fixed in the 11/09/12 nightly, so its not an issue anymore.

Ok guys i have flashed near every rom this phone has ever had and never ran into a bootloop problem. So i had CH 10.2 on my phone for 2 days with no hiccups. Then today after letting my phone die completely "battery death" i pluged it in and now it keeps bootlooping and i cant get it into recovery if i hold down volume down + power it loops at the galaxy s 4g starting screen. If i let it go of the power button at the correct time it just bootloops. anyone have any ideas?

Battery Pull. Hold Vol Up + Vol Down + Power. Whenever The Samsung Galaxy S 4G Splash Screen Comes On, Let Go Of The Power Button And Keep The Volume Buttons Held Down. Should Take You To Recovery

OMG YES!!! I have no idea what i did but i pressed the combo when i plugged it into my computer and it looped the battery screen twice then went straight into CWM recovery did not go through the splash screen like a normal CWM recovery start but whatever i got to remove the rom and flash the new Slim Rom . Anyone have any idea what could have caused this just so i know what to or what not to do in the future ?

To get to CWM recovery on this ROM, simply download 'Quick Boot' application and use it to get to recovery. It works.
Apex launcher crashes as well. I think issue is ROM related. Also, ROM is very heavy, I couldn't find why.
Edit: ROM is snappier after using CM performance features and letting cache do its work.

I got through the splash screen on 1st try.
You should check if you worked according to ROM instructions.
I usually always format system as well as wipe everything twice before flashing any new ROM.
I was referring to :
1. the lack of recovery button on power menu.
2. The inability to use hardware keys to get to recovery after flashing this ROM.
Heimdall One-click (in download mode) and try again.
You're right - I missed that option in developer features - it's called 'advanced reboot options'.
I'd suggest you get to download mode - one click heimdall and reflash this ROM after dowble wiping dalvik, cache, and format system.
I've flashed numerous ROMS to my phone before but have never ran into a problem like this.
-I went back to stock
-flashed CM7, as recommended from the OP
-downloaded and flashed CM10.2 but it gets stuck around 75%
I've been on this thread, and the rom thread as well as waiting a bit, hoping to find a solution or it figures itself out. Nothing! Is it unsafe to pull my battery when its at 'Installing update' (75%) for an extended period of time?
Also, i am on CWM 5.0.2.8
Thanks
I flashed it from ICS (Ultragen) and had no problem.
You can try that as well.

Stability Issues

Having some serious stability issues. Was using catalysm rom and things were... okay. Tried to flash pure nexus with franco and phone didn't wanna boot then was boot looping then would hang on the little circles boot screen. Then tried Screw'd, which I'm using right now, but notice that when the phone sits it also wants to reboot itself but when it does, all it does is bootloop at the google screen or the screw'd bootlogo screen. Doesn't want to start unless I just play around with button combinations until it finally wants to act right. As my daily phone this is a huge disturbance. Also I'm on elemental 6.11
Possible power button problem that is causing the reboots?
and its all fine on stock rom?, i would flash system and boot.img, wipe cache and see how you get on, whenever you get instability problems you go back to stock and see if its hardware related

Then it would be best for you to flash pure stock through fastboot to rule out software.
