[Q] Problem with Omega 12 + Perseus 33.3 start up screen lasts forever

HI Guys
I'm an old iOS user but switched to android 2 months ago with a wonderful Note 2 International running android 4.1.1
​
after one month of use I decided to root my device for VPN service and custom ROM benefits
​
Everything went fine. First rooted with odin 3.07, then decided as most of users recommended to flash ARHD 11.2
After using my device for 2 weeks I noticed poorer battery performance. 4 days ago, After a lot of searching online I decided to flash Omega 12 then Perseus 33.3 for better battery performance and better control of my CPU.
That's what I did. First, wiped all data through CWM then installed Omega 12 ---> Perseus 33.3 ---> clean cached data ----> restored my apps through titanium ----> fixed permissions ---> charged my mobile to 100% then wiped battery stats ---> set gpu to 440mhz and cpu scaling --> frequency responsiveness to 600mhz === every thing went very good with wonderful performance and battery life with 40 hours battery life ,more than 7 hours onscreen and also did couple of successful restarts to change SIM card .I thought that's it "I will stick with this system forever no matter what."
:highfive::highfive::highfive::highfive:​
As I said, after 40 hours of battery life my battery died so I put my note 2 with the recharger while off because it was night time. Next morning, I unplugged my phone then turned it on but my startup screen keep showing the big robot walking with no ending for 30 minutes. Tried to restart the phone couple times, searched online for a similar issue but nothing related to omega and Perseus, wiped cache, dalvik but still the same.
:crying::crying::crying::crying:​
Finally, I restored an image through CMV contains my 4.1.1 old stoke ROM + factory kernel just after rooting. My smartphone now is working fine.
My question now is "Why did it happened? Did this happen with anybody before with the same circumstances? and what is the possibility of this happening again if I tried to flash a custom ROM or a new kernel?
I'm ready for any questions​

Firstly, NEVER let you battery die completly, it is not good for the overall life of the battery.
Secondly if that ever happens boot to recovery and clear dalvik cache and fix permissions. This will usually help.
It's hard to say exactly what cause this issue without a log.
Also, please keep regular backups through your preferred recovery, as this will help if you need to go back.
Cheers,
Evil.

Thanks for the tips.... really appreciated

same
same thing happened to me exactly .
same rom same kernel
i couldnt even restore a previous backup of omega from a week ago - it just wouldnt restore without rebooting !!
also, for my note 2 to work again i had to reflash my recovery (twrp) via odin and reinstall my rom.
i had a whole load of other issues and in all honesty im almost thinking i may have a broken NAND chip - sudden death - not quite, but im patched for that, but may be a small fail on the chip had caused this event , i really dont know.
im back to normal now but im stll very worried about the next few days - please read my other post where i explained this fault at the time it happened.

thanks.

I will look at it... but I think in the mean time I will stick with my original stock and kernel for a while till I have the courage for another rom/kernel trial

[Q] High CPU usage with battery drain , sever lag & freezing !!

Hi everyone,
I have :
Samsung Galaxy Note 2 N7100 32GB
Omega ROM v14 4.1.2
Stock kernel
which I got 7 months ago . I rooted it few days after I got it and installed latest Omega ROM at that time and some later versions of Omega ROMs and stayed on v14 for long time with stock kernel . The device was running normally and smoothly till a week ago when the device suddenly started to lags and freezes and overheats with late response to touch and typing and opening apps .
During this week I installed cool tool and system tuner to monitor the CPU load and temperature I noticed that the CPU load is between 90 - 98% almost all the time with fast battery drain and the device freezes when the load reach 100 % ( not always ) even if I'm not running any app and sometimes the screen does't turn on after turning off till I force restart or remove the battery and put it back . Then I installed latest Omega ROM v16 with stock kernel with wiping cache and dalvik cache without full/factory wipe but the problem still there .
I Installed latest Perseus kernel to have some contol over the CPU and tried to change the max frequency up and down with no benefit !! .
I was thinking about Note 2 sudden death syndrome ( SDS ) but my device is internal 32GB version which means it is unlikely to get SDS and eMMC check showed No. Sane chip .
So, I hope to find a solution as I like my Note 2 and I have no interest to change it .
Thank you all

I suggest to go back to stock (rooted if you want). I was in a similar situation as you are now. I was about to sold my Note 2. I did a factory reset, rooted and installed applications one by one just to see which one misbehaves. I have the perfect phone now

Use it without an sd card....

Thank you both
I started with the easiest solution so I tried to you use without sd card but didn't work.
I gonna try ludovicianul solution and inform you .

Solved !!
I flashed the stock ROM and full wipe/factory reset without unroot then flashed Revolution HD ROM .
The problem was solved in that time .
Then I started to restore my apps by titanium backup one by one and dicovered that A.I.Type keyboard is the reason because when I restored and used it, the CPU usage raised again and the problem returned .
Finally, I opened application manager in the settings and chosed A.I.Type keyboard and did "clear data" and now my mobile runs fast and smooth .
Thank you ludovicianul and Aayush_goel for the help

Glad you got a resolution.
most cooks would advise against a dirty flash and reinstalling apps with tb for the reasons you stated.

[Q] Problem with 4.4.2 and MJ5

Hello guys,
I have some issues while using the latest 4.4.2 DN3 ROMs. Before installing DN3 4.2 I flashed MJ5 bootloader, and it was running for a couple of weeks fine, then the phone started to freeze and reboot several times a day. I thought DN3 v5+ would fix these freezes and reboots but it was no good. I was really disappointed, as I really liked the look and feel of DN3. Now I'm using Revolution HD 31, it's stable (more or less, a couple of freezes and reboots for two weeks) and fast, but I really liked the looks of the latest DN3...
So the question is - what can I do to avoid these freezes and reboots and will upgrading the bootloader to a newer one will help me?

I don't think bootloader has anything to do with it. I was on MJ5 with 4.3 creikelo and NEVER had a reboot or force close. DN3 just freezes after 1-3 days. I had the same experience. It started getting laggy, or better said, the CPU was doing something, hence the lag, and then it just restarted by itself. And I did clean install. It is enough to reat the DN3 topic and see how many people have problems with it - and most still consider it the best ROM... I just went away to another ROM, and will post results in a week hope it doesn't behave the same as DN3

Thanks for the reply!
What ROM did you install? Is it stable?

I had a problem with mj5, my phone froze on the boot and i had to reinstall the ROM.
I think mj5 is for 4.4.2 ROMs, is a older bootloader.

I tried JellyKat 6.7, but seems I have same issue... at first it was getting high CPU usage after a day or two, then phone became so overloaded it reacted to nothing and I had to pull battery out. Then all of a sudden I started getting SOFT reboots (that means only from the point of boot animation, no samsung screen) and I installed Xposed module Samsung Crash Fix and will see if it helps... I dunno, I am begining to believe there's something wrong with all 4.4.2 ROMs Because I never ever had FC, crash or reboot with 4.3 Criskelo....

[Q] Galaxy S4 lost messaging/calling but internet works. Anyone else have this issue?

This has randomly happened three times to me so far on different roms. I searched Google and XDA forums and maybe i am searching for the wrong terms so i will ask here.
I had Hyperdrive installed on my phone for 3 weeks with no problem, i was texting last night no problem. In the morning i woke up and could not send/recieve messages or calls but i could surf the web, check facebook, and everything. This was on and off of wifi. Reboot several times, Full wipe and restored to a previous nandroid, same problem. Another full wipe and reinstalled hyperdrive from scratch, same problem. Finally spoke with Tmobile, no help. Grabbed Carbon rom and then everything worked fine! Why?! Does anyone know why that happens? Same thing happend with the 4.4 Google edition rom. Worked for days then no network. Went back to carbon and it worked fine.
TLDR:Hyperdrive worked great for a week then lost all mobile except internet. Full wipe several times and problem persisted. Changed to Carbon Rom and it worked fine
Used Google Edition 4.4 for days and then it also lost all mobile except internet. Full wipe several times and problem persisted. Changed to Carbon Rom and it worked fine.

What is your modem?

Baseband version shows
M919UVUAMDL

Update it

You can grab the new nh7 modem from Shinyside in development, I ran with my MDL rom no problem.
Pp.

I updated to the NB4 and it seems to be working again. Ill see in a few days if the problem comes back. Its weird that it works great and then out of nowhere it acts up. Thank you for your help!
I will try the nh7 modem from Shinyside if i have the problems again. Or i will just stick with Carbon Rom, it works great but i wanted to try something different.

Nh7 modem has improved my signal all around, I noticed it on my previous rom and going to nh7 stock rom has been a good move for now.
Pp.

So it happened again with the updated modem. After 2 weeks of using Hyperdrive i lost service again. Reboot, wiped and used a backup. Still no service. Wiped and re-installed from scratch, still no service. Updated to the newer version of Hyperdrive, still no service. Wiped and reloaded Carbon and i have service again. I do not get it.

You might have to update your bootloader

Ditto, for Serio, that has been a common issue between KK roms and latest KK firmware.
Go for the nh7 bootloader , don't stress knox.

[Q] Phone freezes when not awake (stock and custom rom)

Hi,
since a few weeks i've got a big problem, my phone freezes to the point where I have to hold the power button to restart it. this started happening when I was on Jellykat v6.7 but still persists after flashing stock rom.
Info:
Flashed latest bootloader
Problem persists on Jellykat and stock, with multiple and stock kernel.
Problem does not occur when running spotify in the background.
Right now I'm running stock rom (4.4.2 from sammy, flashed via odin) with stock kernel and latest bootloader.
When I restart it and check my battery stats I can see my wifi was still working when my phone did not respond, thus the device was on and I was recieving messages while the decive was not awake.
Weird thing is that it works properly when I let spotify play in the background, meaning it doesn't go into deep sleep (I think).:silly:
Right now my device works fine, but only because I have spotify playing the background 24/7 which isn't ideal in terms of battery life and such.
Any thoughts on it?
Thanks in advance!

Still no one? I guess i'll have to survive till I get the note 4 :silly:

Same here
Same thing happened to me when I was on stock rom.. sometimes it froze sometimes it didn't.. (Without spotify)...
Now changed to custom rom... havent faced such issues since then (last one month..not much)
