This is because of undervolting
You can try one of these
1. If you don't need undervolting, then
1. Using root explorer go to /etc /init.d
2. There will be either one of the two files:
--> 00undervolt or
--> bacem_tweak
Just delete it if any of these is present..
Click to expand...
Click to collapse
I think hyperion has 00undervolt script..
bacem_tweak was in jelly blaat but I am not sure about it
2. If you want to use undervolting then
1. Using root explorer go to etc/init.d
2. Search for the mentioned files
3. Open with text viewer
4. Change undervolt vaue.. eg if it is -120mv, change it to -100mv or lower

Hi,
Please try to re-flash Hyperion and do not restore any backup be it titanium backup or cwm backup as it may restore corrupted files. The description of the problem may have one or more cause which as of now isn't clear yet.
Make sure your sd card's 2nd partition is clean as by experience, an un-cleaned 2nd partition may cause problems or boot loop.
I can't say that there's no problem with Hyperion but we tested it several times before release without getting the problem you are reporting.
If you are getting system reboot, this *maybe* caused by kernel panic, it is a situation where the system gets loaded and the only way to avoid lockups is to force the system to reboot.
In most cases, background services/applications may remain in the memory (specially root apps) as they are given high priority and can be locked in the memory. Previous builds of Hyperion has kernel panic tweak adapted from zeps scripts but it works desirable only in stabke kernels. Sadly, the tweak causes some minor problems so it was removed in 7.x.
Here's what you can do, investigate on your device/apps and see how much memory each app takes and how much background services you have (using devtools).
Also, reducing startup applications (using autostarts) will help in decreasing unnecessary system load.
Some quick and handy troubleshooting that you may try:
1. Reflash the rom
2. Reformat the 2nd partition of your SD Card
NOTE:
I/We/DevTeam cannot guarrantee that your phone will perfom as expected (based on our test) if you are using other tweaks and/or kernel.

It is either the wifi driver from WhiteXP's Kernel or the mother of all host file in Hyperion 7 GM that's causing the problem.
NOTE:
Drivers are the bridge between your Wireless NIC and the system itself, it there is something wrong with the driver, we cannot expect the device (your phone) to behave as we would expect.
You can:
Re-download (to make sure files are intact) and re-install (to make sure drivers are properly installed) the wifi driver
Modify your hosts file and/or remove NetForks tweak. Instructions are posted in Hyperion's Thread in Wireless and Network Troubleshooting.

well the reboot problem in my case was due to -120mV undervolting which is pre included in the rom..
and probably this is the same case here..
so please reduce the undervolt value to -100 etc

Changed the value to 100.. Worked well. But when i connect charger. It again restarted... So i deleted the 000undeevolt or whatever that file is.. N working good now.. No restart even on charging...
Thanx again Amin sir for the help...

I'm glad I never had those problems coming from stock rom! Been using Hyperion 7 for quite sometime now and I can say that it's stable and responsively fast. I just hope that the development of Hyperion will be back. :waves at Carl

Constant Reboots!! PLEASE HELP!!!!

Hi guys,
I am using a Sony Ericsson Xperia Arc and am having a lot of trouble with the device constantly crashing and rebooting.
when this first happened these are the steps i took.
i completely wiped the device (factory reset, wipe dalvik cache, wipe cache partition, format system)
i then flashed Baseband 77 using flashtool
i then flashed fxp149 using flashtool
i then flashed Baseband 77 libs using CWM
i then flashed AOKP JB M1-R1 ROM using CWM
i then flashed gapps using CWM
i the reloaded all apps from the market and not applied any backups and yet it still rebooted all the time.
Since then i have tried using
Fusion 3.8
Fusion 3.9
Fusion 4.0
FXP 148
FXP 150
Stock Kernel inside ROM .zip file.
I have also tried putting it back to Baseband 72 but it made no difference.
None of these make any difference to my issue and yet before i had the issue, I had used all of these kernels except FXP 150 and they all worked fine with no issues at all.
I then decided to go all the way back to stock firmware as it is out of the box.
so I used flashtool and flashed LT18i_4.1.B.0.587_(1254-2716).ftf
I reloaded my applications and monitored the device only to see that by the next day, the problem had returned.
I am now at the end of my tether and do not know what else i can possibly do to figure out the issue.
the device has not been dropped or damaged in any way so there is no reason for a hardware fault.
i desperately NEED this device to be working as i use it on a daily basis for my business and cannot live with out it.
IF THERE IS ANYONE OUT THERE THAT COULD PLEASE PLEASE PLEASE HELP I WOULD BE FOREVER IN YOUR DEBT!!!!!!!

i also have a logcat that i was running in the background when one of the reboots happened
not sure if that can tell anyone anything but i have it if it does

First flash stock kernel (587), after flash the rom compatible with kernel. Remember full wipe before

have you tried not to restore your apps? Maybe one of them causes the problem. I'd try to stick with the clean (stock) rom an check if it still reboots. If it does I guess your device is ready for ebay

Could be a loose battery, try a bit of paper between the battery and the cover and see if that helps.

yes i am starting to think that may be my next move
will i have an issue with getting it repaired since i have unlocked my bootloader, flashed different kernels and roms and rooted the device?
if so, is there any way i can get it back to official "out of the box" state?

i have come across something quite interesting.
i had someone look at the logcat i had running live when i had a reboot and it showed that the last thing to function before the reboot was wifi scanning. they suggested i try turning off wifi and running the live logcat again to see if any reboots occured.
it has now been just over 48 hours and i have not had a reboot at all. i know is because my terminal session is still running the live logcat.
is there anyone that could suggest why this may be happening?
i mean, i know its wifi that is causing the problem, but would that be a hardware issue that could be fixed under warranty? or something else?
any suggestions are appreciated as always

i don't think i can help, i just wanna say that i had (have) the same problem. I said had/have because probably I still have the issue, but i don't notice it that often. Before, I had my phone set to ask for pin code, but now I have removed it to avoid being unreachable if a restart occurs. I have raised the issue long time ago, but really didn't find any answer. Other ppl had same problem with their phone (look at the thread i started about this issue http://forum.xda-developers.com/showthread.php?t=1765537)
I also have HTC desire in daily use with CM7.2, that also reboots quite often. So I don't think the phones are broken. More likely it's kenel or rom or app issue, or some combination of those.
If you can tell me how to monitor things, I can do it on both phones, maybe we will figure out what's going on.

if you open a terminal session and type:
su
cd sdcard
logcat >> logcat.txt
it will create a .txt file and put the live logcat info into it.
you need to leave the terminal running in the background to make sure it continues to update
then when you see a reboot just get the logcat.txt file from the sd card and open it in wordpad or something. (notepad doesnt display properly)
have a look at the last thing that happened before the reboot and see what it tells you
mine had info about wifi scanning and showed that it had seen ssids
next step was to turn wifi off to see if the problem stayed or resolved.
good luck!! id love to hear how it goes

[Q] Would this be a hardware problem? T210R hangs, reboots

On my stock T210R I experienced the system freeze and reboot just a few seconds after power up, it was all stock.
I installed TWRP 2.7.1.0, then wiped it off. Installed gr8nole's ROM (Nov '13 deodexed, rooted). After doing so, there was a Kernel Panic on boot, so I installed Blackhawk kernel 2.1.
After doing all of the above, it still boots up, comes to the initial setup page, runs a few seconds, freezes and reboots.
Do you think this is a hardware problem?
Any suggestions before I sell it for parts on ebay?
Thanks in advance

logs?

does it stay long enough to get logs? even if you have to boot a few times to get them onto your pc and check them out from there?
also with twrp there's some unexplained issue of /data getting corrupted on flashes, the only remedy for which seems to be using the format data option.

Sometimes it goes for several minutes before it freezes, especially if the battery is full, even then apps just randomly close without a notification... Maybe storage related?
Care to share how to gather logs?
Thanks

I would use ODIN or KYES to flash it back to OEM stock firmware. Also remove the micro SD card if you have one in there, sometimes corrupt cards can cause boot loop.

fyi- you can get a lot of different info from files that have info to give with
cat /directory/file > /sdcard/output.file
mostly from /proc and digging through /sys
when you get something crazy looking that goes on forever press ctrl then c to stop.

The tablet did the same without the sdcard, and I tried a couple times to do a factory reset with no luck.
The fact that it does the same with a different ROM and kernel is what makes me think it's hardware related

Weird thing... It's been up for a day now, I have catlog running and recording; the only different thing is that I enabled battery saving mode, and batt is 94%; I have not used any apps other than checking battery and running catlog, but I did not have to use it for it to freeze and reboot...
If it is still running by this evening, I'll enable one thing at a time (GPS, sound, etc...)

Awesome to hear sounds like @moonbutt74 was right
Hope it keeps working have fun

Ok, it seems to be hardware, as soon as I disable Power Saving mode, the tablet freezes and reboots.
As I understand, power saving mode limits the CPU to a lower performance tier; so I think the CPU is having troubles.
Oh well, as long as I don't try to mine bitcoins with the tablet, I should be good to go.

I'm running rooted deodexed stock ROM with Blackhawk 2.1 kernel.
But as I mentioned in the OP, the problem was there with the full stock device, the new ROM and kernel were installed after the problem started.

ouch
i think you pegged it right with internal storage being damaged.
only thing i can think of besides getting your money back is do a full data partition wipe and format
and a full system wipe and format
either way that has to suck. sorry i couldn't help.

SOD N7100 - with every kind of rom

Hi everyone!
It is a couple of months that I am having a big issue with my note 2 (N7100). I have continuous SOD. It happens more times a day, especially in the morning when I leave my phone charging all night long.
This issue appeared the first time with an unstable DN4 version (a lot of users had SOD), but after that also with other kind of roms (stock 4.4.2, CM12 based and AOSP roms).
Can anyone help me in finding a fix for such an issue?
Some additional information:
If I receive a message or if the phone is completely charged the notification led is on but the screen does not turn on, if someone calls me the phone does not rings and there is no way for me to know that I received such a call...
Please find attached last_kmsg extracted after last SOD this morning (I can't read it).
Thanks everyone for the support.
Edit: attached the log files of this mornging SOD. Can someone help me?

Wipe data and try to flash with odin from pc stock firmware to see what is happening. Before flashing if you want to be sure that everything is cleaned do this:
put out if you have external SD and go to your recovery and format system, cache, data, dalvik and your internal SD, reboot from your recovery to download (if your recovery ask you for reroot say no) and flash the stock fw.
Notice if your emmc has problem maybe you can't flash with odin and also revive your phone. It is your decision.

Galaxy S9 reboots every 1 min 48 seconds. Fine in Recovery mode

I tried factory reset, removed the memory card, no joy. It does it with battery in any charge state including fully charged. It stays on long enough to check a few things, but since it doesn't reboot while in recovery mode, it seems there is a problem in the software. Running Android 10. Any ideas?

Does it do it in safe mode?
If not it's a 3rd party app.
Stock launcher, right?
By watching running services you might see the cause list before it reboots.
Otherwise reflash it; possibly corrupted or bad firmware.
Use known good rom.

Yes, it does it in safe mode as well.
Yes, everything is stock.
Sorry, I'm a noob, so I don't know how to watch the running services.
I will try a reflash. Any suggestions on where to find a good rom? Does it have to be a samsung rom?
Thanks!!

Try clearing the system cache.
Doesn't have to be the stock rom but it would make troubleshooting easier probably.
A Samsung Experience Center at Best Buys can also run advanced diagnostics on it and reflash it.

Running services shows that the settings app is using 160M of ram on average out of about 1.5G. Everything else is much lower.. i think bc the phone is working on updates after factory reset.. It stays around that level and then the phone freezes before rebooting. It is always 1min 48 seconds.
I would love to try replacing the stock rom. Is that available from Samsung perhaps? If all else fails I will check with best buy...good to know! Thanks again.

Oh and clearing the cache didn't help.

Disable updates. Try disabling the internet at start up... see if that helps.

Ok will try that when I get home and let you know.

Tried disabling internet at startup so no updates and same issue. Then tried just leaving it at the let's get started screen and still reboots. I'm guessing reflashing is next. I found instructions on youtube, do you suggest using Odin3? Also do you know of a safe place to download the stock rom? If not I guess another rom will suffice.

I never had to reflash any of my phones. I'm far from the ideal mentor for how to do a reflash, lol nothing bricked yet.
If you look around on XDA you can find links. Get the exact stock rom needed for that device.
You can use a custom rom but it may end up being a Pandora's box of trouble. I run stock for a number of reasons.
Using the same rom be preferably first to ensure it was a corrupted rom.
Normally they don't become corrupted. Using a different rom introduces more variables. It could be a mobo failure in which case a custom rom might give you a work around for it or not depending what failed. It be nice to know the hardware is good from a troubleshooting prospective... and save you needless hair pulling.
A Samsung Experience Center at Best Buy might be a better option as they can reflash it to the original stock rom.

Hey, just thought I'd let you know that I found the stock rom and was able to flash it using Odin. Unfortunately, it didn't help, but something did change. Now the phone reboots every 30 seconds rather than every 1 min 48. That doesn't eliminate a firmware problem, but it also still could be hardware. Bummer. Thanks for your help and maybe I will try a non factory rom since I've got nothing to lose.

Developer options>running services, ram usage
Watch what ram memory is doing. If it dies at the same amount in use regardless of the rom version loaded, you got a bad ram chipset.
It may be a corruption of the bootloader files allocating memory, I don't know as it's beyond my knowledge base.
This sounds a lot like a memory issue though.

Good point about the rom usage with the new vs. original rom load. Unfortunately, I didn't write down the memory usage before flashing. Now it uses about 1.8G of ram on average. The screen locks up just before the reboot so I don't see any memory spikes. Settings is using about 150M and one UI about 200

Try opening some memory intensive apps and see that kills it quicker.
If you got a bad mobo better to known sooner than latter.

Good idea. I tried a few times but since the phone is fresh, there aren't many apps. I'll have to play around with it some more tomorrow. Have a good evening!

I think you're right about the memory. It works fine in recovery mode, which probably uses minimal memory. And the build I flashed is UI 2.5 whereas I think the old one was 2.0. I would imagine 2.5 is more memory intensive.

My only question if so, is could the bootloader have become corrupted and is somehow causing this rather than the hardware?
Just a guess... if it has basis in fact I don't know.
