Halp, random freezing and reboots, all roms and kernels.

Hi Everyone, i am getting random reboots and freezes on all rom and kernel combinations, sometimes it will happen 20 times a day, some times only a couple.
Anyone know what the problem may be?
Damaged bootloader or something?

OMG same here i get random reboots. though it hardly ever happens to me, nothing is affected and everything is fine, but its just weird. ive not tried the SystemServer Crash Fix in Wanam, though this may help. :good: when it comes to freezes it happens all the time to every device so no real explanation- at least not from me. though greenifying apps and de bloating and etc would help if this is consistant. - i my slef havent de bloated anything and only greenify apps. you could also try a factory reset.

I have tried wanam crash fix still the same problem, i guess its more than rom selection.
What do i need to flash to set everythinf back to factory factory, reflash bootloader the works.

I'd format everything in TWRP, system data cache internal, the lot.
Then power off the phone and it will warn you that there is no OS installed. Then boot to download mode with the button combo.. then flash the latest stock rom via odin
I use v3.09

Hey mate, I have a HK note, can't seem to find latest 4.4.2/4 firmware, so I tried N9005XXUFNF4_N9005OXAFNF4_BTU but failed on ext4 system etc... so i just flashed the latest N4 bootloader, flash twrp, a rom, same freezing issue.

Anyone else?

That's your problem then. You flashed incompatible software on a HK Note. HK notes are slightly different to the normal note due to software. Find the latest HK software and have a nose around the HK guides and read how to fix, it's a common problem (or it was once at least) and can be fixed, so don't panic too much
Sent from my Spectrum ZX +2

Ok cool thanks, i checked samfirmware and nudda?
I have previously softbricked my note when kk first came out and had to flash the chinese Rom / sweet from combo to bring it back, are you saying to flash that chinese rom again?
Im not sure what started the trouble as i was running xnote for a while perfectly.

I found this firmware on samsung updates "N9005ZHUENH4" flashed it, seemed to be ok for the last couple days, today I rooted the phone and boom, back to freezing and restarting.
I re-flashed BL, Modem + CSC from the HK recovery rom, but it wouldn't let me flash AP :s
I just flashed g00h s5 rom, I can't get past the inital setup steps :/
What do I need to re-flash the phone to totally factory, seems there is still something screwing it all up :/

herrrooo???

Have flashed multiple times, cannot shake this problem.

[Q] Galaxy S4 random rebooting after installing CWM

I hava a Galaxy S4 GT-i9505 and yesterday i rooted it and installed CWM 5.X.X.X
but now it keeps randomly crashing, it happened while browsing, while using snapchat and watching photos but also while just watching home screen.
When it crashes it freezes for a moment and then shows samsung logo and after a while it is back up and shows my unlock screen wich i dont have to fill in my Pincode like i have to do when i reboot or boot my phone manualy.
I have updated CWM to 6.0.4.7 but still it is crashing
I am running stock 4.4.2 android only CWM and SuperSU
I have searched for a similair problem but couldnt find anything

Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

I also had such an issue. It happened to me only after installing viper4android on the stock rom.
Deleting the app didn't help.
You will probably have to re-flash the stock rom via Odin. Or change to a custom rom..

I did reroot it flashed stock rom still freezing and rebooting.
I just want to keep 4.4.2 wit root access.
Any other way than achieve this beside cwm with SuperSU?

You need to delete Knox. That's the reason you are experiencing reboots. Afer you root you have to delete Knox.
Get the Knox removal script from here and flash it:
http://forum.xda-developers.com/showthread.php?t=2507931
CWM is totally unrelated to your random reboots.

Thank I will try this tomorrow.
Although when I first booted my phone after rooting it asked something about disabling Knox.

Disabling and deleting are two different things

Good to hear that still got hope

I hope you did a full wipe before re-flashing stock rom, right?
Doing a dirty flash will not help you much.

Yes full whipe factory reset dalvik cache data files, all even formatted my SDcard

[Q] Safest way to load 5.0 on my rooted Note 4?

Hi guys,
Have just spent the last couple of hours trying to research this but still not quite sure what's the best (safest!!) way of upgrading to lollipop on my SM-910G. I am rooted and currently on 4.4.4 and when I try to do an OTA update, I get the msg "The operating system has been modified in an unauthorised way.... etc etc"
When I connect via Kies, I get a pop up msg telling me that lollipop is available however when I try to update it tells me that I have to be unrooted. I read an article where some guy messed up his rooted S4 while trying to update via Kies. Can't afford for that to happen on my phone, I've backed up all my apps and data via Titanium Backup but now need to know what the safest way is to upgrade and keep all my settings etc.
I've downloaded the right 5.0 ROM (N910GDTU1BOC5_N910GXSA1BOC5_XSA.zip) for my model - am I correct to say that if I flash via Odin, I will lose all my apps and settings (and root)?
If I want to update and keep all my settings, am I safe to unroot via SuperSU, then update via Kies? I've read about how unrooting via SuperSU isn't really a complete unroot?
At the end of the day unless I'm 100% certain I will probably stay on 4.4.4 since there has been some horror stories with battery drain and stuff on 5.0

Has anyone been in a similar situation?

hi
Just a few points ...First if you " dirty flash" official stock Rom with Odin, then you will lose root ( so to me there is no need to unroot first ) However you do not loose any 3 rd party apps or settings . Also i never use Kies as my personal experience is that it is a waist of time .Regarding Lollipop well i have flashed several newer " version"/changelog/dated of Lollipop 5.0.1 over the past months and all of them have been good to me...( ..overall.) No real battery drain ,no lag ( only recent button and one " Samsung bug in the setting " Accessibilty" .
All my "problems " on Lollipop, on and off, was caused by 3 rd party apps
eg.Past few days i had suddenly random reboots over and over .i reflashed Lollipol ,i factory reset ,but the random reboots continued .
i then started to install all my +_ 162 ..?? apps one by one and checked
Eventually found my culprit ..'Greenify " (the experimental paid ,bolt on package, which is meant mostly for Xposed module with few functions you can also use without Xposed eg "don't remove Notifications " and Greenify system apps l)
After using Greenify for months with no issues it suddenly started giving problems .
So i could have given Lollipop the blame for my woes but i did not .
Yes I do believe Lollipop has issues ,but overall i cannot complain .
yes ,Titanuim is the way to go .
Also i "unrooted " via SuperUser app once, no problem at all, but then why do this if you just flash over it and root is gone
Bottom line ,
you can be "stuck " on Android v4.4.4 hoping and waiting .......?
or faceup to Lollipop ?
its your choice ?
good luck

Hey willcor thanks for the reply! Good to hear your experiences with this. Interestingly I've had a similar problem of sluggishness, lag and random rebooting (multiple times a day) on my Note 4 running kitkat. This went on for about 2 or 3 days. Tried installing some recently installed apps thinking it might have caused it, and now it seems it's fixed itself, I think??
Even pulling the battery and restarting often took ages to boot. Took my 128GB SD card out and tried to boot thinking maybe it was the card but it still lagged and restarted by itself. Like I said it seems ok now and has been ok for the last few days, but now that you mention Greenify, I have that installed too along with a few exposed modules. This rebooting problem is what motivated me to think about upgrading to lollipop to see if it would fix it.
Going by what you said, if I am not going to lose apps, data and settings, then I might flash to lollipop, then re-root. Sounds like the way to go. Maybe...

hi,
Just a quick remark. When i was on Android v4.4.4, most of my issues eg. Private mode S HEALTH... (yes i know there was quick fixes /patches , that you could apply) Play store not installing apps, lags from time to time etc was caused by Xposed Framework. As far as i can remember Xposed was never optimise for Android v4.4.4? As "good" as Xposed was, it gave me "terrible headache /problems" on my Note 4....... even after uninstalling Xposed it broke some apps functionality! (This is a fact for me) . but yet, on all my other devices, no issues ! As stated in my previous post, that Lollipop experience, has been over all, very good for me.,(I have accepted the few bugs, that comes with every software update be it Android v4.4.4 or Android v 5.0.1.)
Lollipop also enabled me to use other apps /features eg Network Toggle app (change network only to LTE or LTE/3G or 3G only.. root required)
Bottom line
for me is.... yes, Lollipop has issues, but most of mine was caused by 3rd party apps not optimised 100% , work smoothly on Lollipop.
good luck
..............................
post note....
Titanium, i forgot, you might have some minor issues at first. Titanium could not find backup folder on my ext sd same as on Android v4.4.4) , so i used NextApp Sdfix (Play store, free app) Titanium, then was able to locate back ups. Again yesterday, i factory reset my device because of a Nova launcher, toggle notification issue and because i also wanted to for a period of time.
Titanium could not write and above NextApp Sdfix said i had no write premisson after running NextApp. i formatted my ext sd on laptop and NextApp did its work and Titanium working 100%
Just thought to make you aware if issue arrived.

Thanks... I forget all these root features have to be redone. I've also given extsd access on kitkat after rooting. Will have to do it all over again I guess!

Ok just a quick update. Flashed to 5.0.1 with Odin and rooted with CFautoroot. Everything seems to be ok apart from after rooting and rebooting, I got a "could not do normal boot" msg, saying that the phone was in download mode and not to disconnect the target. I pulled the batt and booted up normally ok. Checked in Titanium and found root access ok, activated write to SD and all seems normal.
Things seem a bit sluggish with lollipop, so I uninstalled xposed (which now won't work on this version), greenify and some other apps, and booted into recovery to wipe cache partition. When it was done wiping the cache and said to reboot, I got the same "could not do normal boot" msg. Once again I pulled the battery and it booted ok.
Not sure what has happened or if anything is affected - should I re-flash 5.0 with Odin and re-root all over again?

hi,
i am sure i read somewhere about.re: your remark, when you rooted and got a msg, with
"could not do a normal reboot... I am sure it could be ( @ Chainfire,) Cf autoroot website not sure.?
I would have search for a answer /reason!/ explanation Then i would afterwards, reflash Rom. (depends on you)
Just a quick question.... At what stage did you uninstall Xposed....? before /after flashing etc. i stated before that i found Xposed "broke /caused issues after i uninstalling it. (facts about two or three times it happened , in past )
Also i had no problem in using Greenify again (i have re installed it) its just the donation /paid / experimental package i am a bit hesitant with.
good luck

Hey guys, I have since reflashed and rerooted and now seem to have less problems, although the phone is still sluggish, randomly locking up and restarting , and sometimes restarting to the green android "could not do normal boot" screen.
Question now is, can I boot into stock recovery to do a factory reset? I've done some research but the views seem conflicting. Is this recommended, will I be stuck in a bootloop and will I still be rooted after the reset?
I never did a factory reset when flashing from 4.4 to 5.0.1 so I'm hoping this will fix the issues I've got now.

apps crash, phone reboots

I had been using rooted kitat for sometime. Everything was great. Then I installed a 5.0.2 Russian stock ROM and that ran fine too. But after a few weeks, I have been getting this problem. It seems the phone doesnt load apps and/or they keep crashing. The phone eventually hangs and reboots, and even gets stuck in a bootloop at times..I have tried flashing alternative roms through odin, i cleared the cache and wiped data through recovery but the problem persists...most of the apps that are glitching are google apps and sometimes systemui and phone....What else can I do?

im having the same problem on my G530H. does anybody know how to fix this???? its really annoying

Maybe you didn't factory reset before update to 5.0.2

Samsung Galaxy Note 4 - SM-N910C - Hotboot issue...

Good Day Everyone...
I hope you all are fine...
Allow me to explain my story till we hit the big problem that is the hotboot/fastboot...
10 months ago, I bought Samsung Note 4 SM-N910C ... Was switching from Broken screen Note 4... I had a Nandroid backup of it... but while restoring I messed up badly as I wiped the new device IMEI that time... but I managed to find someone to fix the phone and create a backup... Now Why did I change my phone again...? Battery degrading, phone heating and of course from time to another I must restore the IMEI backup as it gets corrupted suddenly and randomly... In addition to the Note 4 Great Offer...
All 3 phones were SM-N910C, however the first 2 came as KitKat 4.4.4 and the latest phone came as Lollipop 5.0.1 ...I didn't really care much as I grabbed the Nandroid and restored it carefully... Everything works great, Until after installing Xposed... softboot / hotboot / fastboot / quickboot whatever you wish to call acts similar to REBOOT but without shutdown... This issue is Critically annoying as I play from time to another with Xposed and rebooting sometimes don't give Xposed enough time to load the modules ... In addition the SIM lock is active at every reboot and the loading TIME...
I took a backup for all my application on Titanium Backup... Preformed a clean Install of Kitkat 4.4.4 ROM on the phone and restored the applications, Hotboot remained the same... I thought perhaps Xposed is the issue... So I went to ADB command ... adb reboot fastboot ... same results ... phone keeps REBOOTING without shutdown...
How Reboot without Shutdown? Do I know the difference between Hotboot & Reboot?
Yes I do know the difference...
a Reboot would go to shutdown animation, reboot to Samsung NOTE 4 then load the BootAnimation followed by its loop till device has loaded, reboot clears all memory and reload everything, Enter SIM Lock and takes time...
a Hotboot would go immediately to BootAnimation then loop while in the background it's just refreshing the Apps and services briefly, no SIM Lock needed, it doesn't take time...
My HOTBOOT is doing same as REBOOT but skipping the Shutdown animation...
So my Question: What is wrong with my Hotboot? Is it Lollipop? Do I need to check something?
I Thank you all for your patience and reading all what I wrote whether you Answered or not...
P.S: Some Xposed apps are acting weird on this phone compared to the 2 previous Note 4 phones...

Lollipop 5.1.1 fix the "Hotboot" problem, also disable fingerprint (it's the main cause).
Next iteration of update will fix fingerprint problem.

So I should Flash lollipop 5.1.1 then flash back to kitkat?
I have done many tests for hotboot via trying multipl 4.4.4e apps... 2 apps out of 6 managed to hotboot...
Xposed installer failed...
TWRP manager failed...
APM+ failed...
Fastboot failed...
Simple reboot success...
Root toolbox success...
I have Kitkat 4.4.4 on my phone... Rooted with TWRP recovery and xposed installed... Busybody is present... Selinux enforcing... What more information do I need to provide?

XPOSED is still problematic on TW odexed Lollipop ROM, so it is not recommended to install EXPOSED on your Note 4 with Lollipop.
Fingerprint causing many problem on Lollipop 5.0.1 - 5.1.1 (sudden lag, random hotboot, random apps kill), so disable fingerprint while you are on Lollipop.
Some said that COI update (5.1.1) fix fingerprint bug.

After a few KitKat updates my phone started random hotboot too.
On lollipop 5.1.1 (COH update) it's all gone with 2 drawbacks.
Fingerprint must be off or I'll get another random hotboot+random lag.
Xposed Framework is out of the question for Stock 5.1.1 ROM.
The only way to install Xposed is to flash non a TW ROM or flash a Deodexed Stock ROM which is not my preferences as XPOSED for 5.1.1 is still in ALPHA stage.
COI update said to be the best update as it fix fingerprint bug. But COI update is still unavailable in my country.

Since no solutions were found...
I'd share mine... You need Root...
Simply use this apk:
https://play.google.com/store/apps/details?id=simple.reboot.com
Create a widget and drop it on the home screen...
This solution is temporarily until the cause is found which will likely take a lot of time...
