[Q] JVP really slow when booted with bluetooth on

I've flashed new JVP into my SGS using ramad's deodexed firmware with CF-root kernel and JKay skin. Then I restored my backup and used it for some time. After one reboot I noticed that it suddenly got much slower than it was - before I got quadrant score of 1900-2200, after it dropped to ~1300. After some investigation I found that there must be some problem with my settings - if I use some "clean" database (com.android.providers.settings) it works like it should but with my backed'up data it works fine only if I boot it with bluetooth turned off.
Can someone suggest what could have I done wrong?

Try to re-flash and use the stock Kernel, then see if you get the same problem. If not then only restore /data applications (Never restore /system applications) and see again if you get a problem, and so on..
You need to find out at which stage you get the problem, this could help isolating the problem so you can help finding a solution by finding out what cause it... in the way you are asking every member will give you a theory, try to find out by your self, devices are all different and so are the applications/settings/Kernels are all different on members devices.

Sorry for beeing so vague on the first post.
I did tried to isolate the problem - reflashed everything at least 10 times with different configurations. The result is I can show the exact moment when after restoring the backup phone starts to act weird.
Unfortunately the problem probably lies somewhere in my old settings as restoring only this one piece into the clean firmware (or - as my steps were - after flashing cf-root and installing theme) doesn't activate the slowdown. Unfortunately I also did a mostly clean restore - restoring only things I really need (contacts, bookmarks etc.) and only a few applications with data and for the rest of backup only applications. It didn't help.
Today I'll try another way - I'll reflash it and then restore only applications without any data and see what would happen.

Ok. So I did another round and for now I'm satisfied with the result.
What I did was:
1. reflash deodexed JVP
2. restored my user apps with data from backup
3. restored pieces of system data and configured missing settings
it worked fine up until this point
4. reflashed to CF-Root kernel - it seems this broke my setup. I'm certain that there must be something in my config/installation that when added to CF-Root and bluetooth introduces slowdowns.
5. as I needed my theme I just flashed it using CF-Root's CWM and after that I reflashed back to the stock kernel - everything returned to normal - quadrant score was back up at ~1300 (from around 700 with CF)
6. as I also wanted to convert to ext4 I flashed a Speedode kernel and I test the speed - it showed stable 1300
7. converted to ext4 using SpeedMod's CWM then rebooted and retested with quadrant - it holds fine at around 2200.
This closes the case for me for now

Good work, and you did it all on your own
Now you know what was the cause for your trouble and how to deal with such problem next time.

For others that find themselves in a similar predicament, but want an alternative method (or workaround), then keep reading.
I too am using Ramad's deodexed Rom's with CF-Root & have similar problems.
Ramad, I know it's not your Roms.
There is definitely something flaky after flashing CF-Root (no disrespect to Chainfire) , as I can replicate the faults again & again & again, with only the deodexed Rom & CF-Root, APN & WiFi setup. No user apps or anything else on the phone at this stage.
Certain problems then arise (lag is often noticed first) after the phone is restarted while ever WiFi & BT are both turned on prior to restarting the phone.
See my posts in the CF-Root thread here (Posts #2151 & #2152) which lists a few other problems which arise after flashing CF-Root, along with my workaround in post #2152.
It'd be great if Chainfire was able to get this issue fixed, as a workaround is never as good as a permanent fix.
If anyone found my workaround worked for them, feedback is definitely welcome.

Acer builds ROM and KERNEL testing

ok i started this for myself, but the info may be helpful for some. Here it is and how i got to it
I only used Acer based roms because that is what i prefer. Every time a new rom was flashed i would wipe EVERYTHING then format system and data and flash the rom. I would then root and remove everything i don't use and set the tablet up for my daily use. This procedure was the same for every rom tried and apps installed were 99% identical across the board.
When swapping kernels within the same rom i would only wipe cache and dalvik cache then flash the kernel
For the testing side, after the rom and kernel combo were set up as needed, i would reboot the tablet and let it sit for 5 minutes to settle in. Then i ran the following tests 5 times each then proceed to the next test.
Vellamo
LinPack Multi-Thread
LinPack Single-Thread
Quadrant Standard
Antutu
CF-Bench
Don't ask what these tests actually test cause i really have no idea. Everybody prefers different testing apps for one reason or another so i did as many as i saw people mentioning.
These are only results from these tests. Not reliability, lag, battery life or anything else. If this becomes useful for anybody i will update it with more info as i do more testing.

Google Docs that please

NexusBeam 4.1.0 issue

Hi everyone,
I got this Rom installed + Glados 2.3 Kernel on my I9023EU.
This combo solved:
-ICS increased battery drain: lazy governor, 100 mhz min freq
-lag in app drawer
Issues:
-font installed not properly displayed
-random reboots (no OC)
any hint?
EDIT:
-WiFi staticIPs not working ... when asked for subnet mask, only the last segment is to be inserted. Then it works..
EDIT 2:
-upgraded to GlaDOS 2.4
NEW ISSUES (not related ti the upgrade, i dare to say):
-BLN BLINKING: if when unlocking, lights are in the off-phase of blinking, the remain off.
-DSP MANAGER 2.0: Equalizer is not working
Thanx a lot

No problem with the ROM NexusBeam 4.1.0, but I didn't change the kernel...
Maybe, if i have any time this weekend, I'll try to install Glados 2.3 Kernel.
I will report issue(s) if I have some.

Try to use the new matr1x kernel

anyone of you heard about wipe cache/dalvik/data
even AFTER having flashed NB4.1. ?
someonedon'trememberwho said this solved some probs..

No problems with Nexus Beam, the best rom at all (imho).
Now i've tryed to use Glados 2.3
Have you wiped data/factory and cache before installing Nexus Beam?

yep. and someone says also after... what about it?

I encountred some random reboots while making a call with 3G enabled.

Random reboots seem to have disappeared after reinstallation. This time I flashed nb4.1 and glados2.4 at once, without reboot inbetween.
Still short battery life and no correct fontinstall

wifi issue

Is there any way i can extract wifi component from one ROM and use it another?
i've installed cyanogenmod 7.2 but can't connect to hidden wifi at work. I don't have access to access point to enable broadcast.
I've tried different ROMs and was able to finally get it to work with DARKSIDE SENSE v4.0 ROM with thederekjay's Kernel. But my phone keeps randomly booting and is really slow compared to cyanogenmod (200 vs 400 free mem).
So I flashed back to cyanogenmod and tried wifi module (bcm4329.ko) from DARKSIDE SENSE v4.0 ROM. But wifi doesn't work, I can't even enable wifi connection.
Any help would be greatly appreciated.
Thanks

That module is compiled for a very particular kernel, i.e. the one it came with. To regain some RAM you could de-sense the ROM and maybe run v6 supercharger to make the OS more aggressive about closing apps.

so I switched back to Darkside snese but my phone keeps randomly rebooting. I've tried flashing the ROM multiple times, clearing cache and formatting partitions. nothing seems to work. I was able to get 3 (of approx 30+ reboots) kernel panic logs: (/proc/last_kmsg )

Can some one look at these logs and see what's causing the reboots.
thanks for the help

[Q] NOOB question

Please, forgive me if this isn't the right place to post this question, I just find the whole forum a little complicated for me to understand (obviously, I'm not a very intelligent person, not even intelligent).
So the thing is a video on YouTube about overclocking the Samsung Galaxy S4 up to 2.3 GHz and I flashed this kernel: http://forum.xda-developers.com/showthread.php?t=2294083
And I had Rom Toolbox and the app KTweaker (the app that came with the kernel) to set the CPU and when I used KTweaker to do so it worked perfectly but when I used ROM toolbox to edit the values my device rebooted, even the smallest change with Rom Toolbox made my phone reboot. I used to edit the CPU with Rom Toolbox before flashing this kernel so I don't think it's the problem.
After that, I wiped cache, data and dalvik and installed No-frills CPU Control but when I overclock my phone with it and I go to KTweaker app to check if both have the same values and the apps tell me different things
Also I noticed that, before wiping, I could go from 1890 GHz to 2300 with no trouble both max and min. After wiping, if I do that, my phone reboots.
Do you think you can help me? At this moment I don't know if my phone is overclocked or not.
Also I editted the GPU. Mainly because of hard gaming.

So what model do you have?
The kernel you flashed is for the Verizon version of the s4. You can't flash a kernel for another phone onto yours.
