Here is an update..I was finally able to get the baseband back in rasbeanjelly..I simply flashed the old Twrp (2.6.0.0) recovery & then flashed your Kernel (1.5.9j) again..
Baseband back
It was the problem of recovery..Not your Kernel :good:

@Sak3ater
Are you able to get data connection? I got the baseband issue solved but cant connect to data (wifi works fine) with stock (0.84) and hybrid (0.33/0.84) radios.
Thanks for feedback!
Yes.. Data connection working fine.. Just tested it now.. I am on radio 0.84 .

Got it working. Flashed stock radio and then flashed the hybrid radio without flashing the ROM or/and kernel. All good so far with all stock. Will report back after I flash kernel. Thanks again!

Any idea as to why the Android system is using so much of my battery? I looked at better battery and it suggested the cause may be
"system_backoff". I've since gone back to Franco, as I need my phone today. If you guys have any ideas as to why this may be happening, I'd love to hear them.
Thanks!
After using 1.5.9 j for one full day. Wanna report something..While trying to scroll the App drawer screens very slowly.There is a little jerk while swiping there..Also try to swipe the settings menu & there is a little jerk there as well..Vertical or horizontal,this jerk is there when scrolling slowly..
Anyone else experienced this thing
PS:Just to confirm if this is the Rom issue,i flashed another Kernel & all fine now..
Edit:Flashed 1.5.9j again & everything seems to be normal now..Weird things happening today lol
Accuracy & Jitter Filter were turned on that's why i was experiencing the Lags while scrolling..All okay now..

It's not the kernel..Check your Apps.This Wakelock is the reason that Android OS & Android System keeps your phone awake..
The Apps that i could point out are Facebook,Chrome or greenify..
Excessive use of touch wake or touch control also triggers this wakelock..The bet possible way of troubleshooting is by disabling the Apps one by one & check if the wakelock stops.
Ps:I've been using touch control on 1.5.9j & this wakelock hardly triggered for not more than a few secs..This Wakelock is random.Sometimes it's high for me as well.& sometimes it hardly shows up.It's up to you how you identify the root cause.It's the not the kernel,that i can guarantee because this wakelock shows uf in all custom kernels including Franco as well

Don't know about you guys, but I'm extremely satisfied with Stratosk kernel.
I'm running PA and semaphore 1.5.7, I have excellent battery life, always over 5h of SoT with normal use.
Gaming performace an user experience is perfect and my n4 i cold as ice, even when on charger while web browsing.

I'm sorry, Semaphore does not include any sound 'fixes'
Thank YOU for your kind words, my friend!
Thank you!
Semaphore is my favorite... after Franco's, stock, faux's, Matr1x, Harsh, bricked, anarkia1976' and some others (that I didn't test yet)... :laugh:
I'm just kidding. Thanks so much, mate!
I have to thank you, once more, Strato, for your time and work, in 4.3 too. I have the best scrolling experience ever with semaphore. Especially in falcon pro app, nothing else gets near.
With touch control support and your automatic answer mode my N4 is like a dream machine.

You should've said that semaphore is my favorite kernel..franco & stock comes next.. Say the opposite while in Franco's thread
Ps: this kernel is really something. Scrolling is better than the other best kernels out there.. thanks a lot dev for giving us such a great kennel..

Just moved onto AOKP 4:3 which is JSS based so just to be 100% which kernel do I need ? and just flash as normal ?
TIA [haven't followed to closely and don't wanna flash the wrong one
If it's jss then flash semaphore 1.5.x j

I would suggest you to flash 1.5.9j. Although, it's a test version, it's work fine.
Otherwise, you may try 1.5.7j (I hope AOKP use default SELinux configuration.

I fully respect davidbar93's opinion.
Hi,
I use stock thermald. I don't know the exact threshold.
I don't touch and I don't play with thermal protection.
Stock should be 60c CPU and 37c battery.Hi,
I use stock thermald. I don't know the exact threshold.
I don't touch and I don't play with thermal protection.
I flashed 1.5.7j as I'd already downloaded in prep [I was just asking to be 110%]
Anyway @stratosk
Kernel is working just fine with AOKP - I've not tried Touch Control yet - not sure if thats in the 1.5.9j kernel ?
As always thanks and great work :good:

About Double Tap to Wake.
Implemented from scratch and hints from show-p1984 and LG G pad kernels (thanks).
The basic idea is known: touchscreen remains _always_ powered to handle input events
and wake up the device with a double tap.
User have to double tap on the _center_ of the screen (to limit accidentally wake ups).
Double tap is disabled by default. To enable it run the command bellow as su:
echo 1 > /sys/devices/virtual/input/lge_touch/dt_wake_enabled
If you run the above command during screen off, the command will remain pending until
the next power on. Then it will be actually executed.
Touchwake functionality is still implemented and it should be disabled if double tap to wake
is enabled.
1.8.8 (22/12/2013)
- Linux kernel 3.4.75
- dyn_hotplug: Activate the driver 1min after boot (because during init scripts execution all CPUs should be online to get initial settings. Fixes issue where a CPU governor could be set with default performance governor. Thanks to ihancioglu for reporting and reproducing the issue).
- cpufreq: set initial utilization to zero on device CPU addition

Last Updated 2016-05-19189About undervolting
As you may know, APQ8064 comes to 4 versions (PVS bin): Slow, Nominal, Fast, Faster.
Every bin has it's own voltage table. Nominal bin chips use lower voltages than Slow bin,
Fast lower than Nominal and finally Faster even lower voltages.
Stock kernel uses a paramater boost_uV. By default, is added in voltages but it can be disabled.
The value of boost_uV is 0 for Slow bin chips and 25000 uV = 25 mV for Nominal, Fast and Faster.
The boost_uV may be disabled (= undervolting by 25000 uV in Nominal, Fast and Faster) using this command:
Code:echo n > /sys/module/acpuclock_krait/parameters/boost
I implemented 3 more paramater that handle undervolting:
- lower_uV: undervolting value for lower frequencies
- higher_uV: undervolting value for higher frequencies
- higher_khz_thres: above this frequency (default 1350000KHz) higher_uV will be used. Else lower_uV will be used.
Undervolting value is subtracted from stock voltage. The final voltage for each frequency is calulated:
Vdd(final) = Vdd(core) + boost_uV - uV
So, to undervolt frequencies 384000-1242000 by 25mV and the other frequencies by 12.5mV use these command:
Code:echo 25000 > /sys/module/acpuclock_krait/parameters/lower_uV echo 12500 > /sys/module/acpuclock_krait/parameters/higher_uV
The higher_khz_thres maybe changed using this command (for example to use higher_uV from 981000KHz):
Code:echo 918000 > /sys/module/acpuclock_krait/parameters/higher_khz_thres
Also, I added a debugfs file (acpuclk/acpu_table) to show the acpu table frequencies and voltages.
For example to get the information about the current status use this command:
Code:cat /sys/kernel/debug/acpuclk/acpu_table
and the output:
Code:CPU PVS: Fast Boost uV: 25000 Boost uV enabled: No Higher KHZ threshold: 1350000 Lower under uV: 37500 Higher under uV: 25000 CPU KHz VDD(stock) VDD(final) Difference 384000 875000 812500 -62500 486000 900000 837500 -62500 594000 925000 862500 -62500 702000 950000 887500 -62500 810000 1000000 937500 -62500 918000 1025000 962500 -62500 1026000 1050000 987500 -62500 1134000 1100000 1037500 -62500 1242000 1125000 1062500 -62500 1350000 1150000 1100000 -50000 1458000 1162500 1112500 -50000 1512000 1175000 1125000 -50000
