People,

please don't screw with charging currents/voltages without fully understanding what it DOES to the battery that's being charged... Worst case scenario: you'll blow your battery up... LITTERALY... best case: you'll reduce it's lifespan... It's charging slowly because it's supposed to charge slowly... Sony (and any other battery, FTM) aren't that great... those might not be able to withstand everything you throw at it...

Written from electrical engineer's perspective, just my 0.02 €
[Sony Xperia L] varun.chitre15:
As long as the current is less than max rated current it is fine.

XL's battery has 1800mA as max rated current(according to logs) whereas it charges up at the rate of 1000-1200mA. The current is rate limited in all pm8921 charging modules to reduce heating. But it does not damage it in anyway as long as the above condition is satisfied.

There are millions of people using such feature in almost all flagship phones and in many cases overriding max rated current with no explosion kind of reports.

Secondly, the pm8921 charger polls the battery health and it's temperature every second and it triggers eoc signal immediately after a max threshold is reached which ultimately stops charging. And at extreme times can generate a reboot as well.

Electric hardware is always manufactured to handle such situations flawlessly.

If you had checked out the post #1 there is a disclaimer over the top. And people have come here in this forum by accepting that disclaimer.

You should have explained people in a bit more better way, or had researched a bit about what charging module the phone uses, what security measures are taken to handle such uttermost situations rather than scaring them "Hey refrain from using this thing". Because I don't work for blasting people's phones and have taken necessary care at what max value can be set.

Plus the feature is not forced and everyone has control whether to use custom values or to use built in mechanism.

Hope it doesn't make situation like this

[Sony Xperia L] [QS]:
Okay... I never said "refrain from using" your kernel, you did a decent job, and exposing this setting (among others) made it possible to tweak the phone as anyone wishes and likes. I only said don't "screw with currents/voltages". That doesn't mean "don't touch that stuff at all"

Also, you should NOT assume I haven't checked relevant information in regard to batteries, charging modules and "security measures" (let's call them cutoffs). I'm aware of how phones or any other gadgets handle electrochemical components and I'm not implying you're trying to blow up other people's phones so there's no need to go all tech-savvy on me (as I said your work is appreciated) ... Google is everyone's friend but experience with stuff is equally if not more important.

Bottom line: I just wanted to say: Don't screw with voltages and currents, you cannot trust cutoffs as those can't and shouldn't be always and completely trusted (Previous post is a bit extreme but we all heard of exploding or overheating phones, sometimes due to battery heat - all those phones had charge controller chip/instructions that failed to perform). That's all. You can experiment with stuff... but take it slow. If you could make XL cpu run on 2GHz, would you not? That doesn't mean you should or else its poor silicone soul could say bye bye to the hardware.

So again - you did a great job with your kernel - users go slow with batteries - if you notice it's heating up out of proportion dial it down a bit.

That sounds better?

for 15.3.A.1.14 ??

Hey Varun,

I am on the latest version 15.3.A.1.14 and I want to try this kernel but wanted to know that should I try the existing 3.1 version or should I wait for the latest release as you said it will be soon.:D:D
[Sony Xperia L] Yoru9102:
Hi, I'm new in flashing kernels

Is it compatible with stock rom and firmware .14 ? this delete my data or all is same after flashing? thanks and sorry for being noob xD
[Sony Xperia L] przemek4113:
Hi, the kernel is compatible with the latest stock firmware 1.14.I'm using it right now and have no problems.Flashing kernels doesn't wipe your data, everything will stay.

Its my private AOSP build.
[Sony Xperia L] :
Wow! Great, Looking forward for your kernel. Great work!

And by any chance you happen to solve deep sleep and Internal storage issue in your Private AOSP build?
[Sony Xperia L] Marius Cristian:
[MENTION=4309448]varun.chitre15[/MENTION] just to avoid the confusion around here...you're working with AOSP sources in order to release a new 4.4.2 build with some bug fixes(and indeed a compatible kernel) or you're just building a kernel compatible with buggy 4.4.2?Thanks!
[Sony Xperia L] XenodromeZynosZ:
:angel: The screenshot says it all . it really look like Android 4.4 . Dude,Honestly i said,if you can develop kitkat and kernel for our device , For sure people will donate to you .if you release the AOSP kitkat ROM for our beloved phone , you would be a HERO because there is no one willing to create it for XL,even uberlaggydarwin . if you release it for us, i would be the thankfull person in the earth .Honestly, i would say that i will donate to you . just PM me and tell me what the cost..hehe :laugh:

Good luck! :)
[Sony Xperia L] Jstrax:

Does this mean that the next version of this kernel will have Android 4.4 for XL? If it does, THAT WILL BE AWESOME!
[Sony Xperia L] arjit mehra:
Hey man I've been having this really bad lag issues at timr and so many random reboots.. It's really annoying :/ i wish you would release the next build asap..
[Sony Xperia L] :
This is to all Kernel developers. I don't know why anyone didn't notice this before but as ALL kernels are based upon 15.3.A.1.12 and not 15.3.A.1.14

On installing Custom Kernel on latest firmware ie: 15.3.A.1.14

Then going into settings --> About Phone --> Softwareupdate --> Refresh it you'll receive a notification about System update of 15.3.A.1.14 itself which won't go! I have tested with this Civic, Phantom ,Vengeance and Thunderzap ON STOCK and on custom rom but same results.

Its my kind request to update your base guys. The reason probably noone complained about it is there are very less users using CWM with latest firmware.
[Sony Xperia L] siankatabg:
Tell on Sony to release source for the latest kernel and im sure that all devs will update their source :)

And please dont spam all the kernel threads...
[Sony Xperia L] hashroot:
Hi which kernel source you have used? https://github.com/varunchitre15/android_kernel_msm8930 This one? And What things are working?
[Sony Xperia L] varun.chitre15:
Those are outdated. I made everything from scratch again.

Everything is working except for the bugs in any 4.4 ROMs.

I have begun my work since I got the kernel to boot.

I will keep you all updated on things I fix.

Are you porting caf kernel?
[Sony Xperia L] supreethms:
I want to keep the vibration settings a little higher. But not too high.

Can you please mention the DEFAULT value and at what HIGH and SAFE value the phone can vibrate without a problem?
[Sony Xperia L] varun.chitre15:
Done already. Thats what TZ-4.0 and 4.4 kernel is based on

Have a look at post #3
[Sony Xperia L] supreethms:
YES. I saw Post #3.

But.. As far as i observed in the file, the default was 30. And the mentioned range is 12-31.

So, increasing it by 1 won't make ANY difference at all.

So, i was in a little doubt.

PLUS, i am not able to edit the "level" file in the directory. Even if i edit, and restart the phone, the value stays at 30. It shows absolutely NO CHANGE.
[Sony Xperia L] siankatabg:
Now i have a hope for bugfixed AOSP(CM) rom for our devices.Thx for your work :)
[Sony Xperia L] joebonrichie:
I have created two bulk updates to the Xperia L kernel to update it to 3.4.79

Commit: Linux: squashed update from 3.4.42 to 3.4.79

Also here are where you can find incremental updates which you can just patch, unless there is a better way lol.

hi, I'm using XperiaL C2104 + stock rom 15.3.A.1.14 (generic world-a)...

in the past my wifi tethering worked fine, but now after install thunderzap 3.1

the wifi tethering stop working ... is this a problem with the kernel ?

tks...

have you flashed thunderzap wifi modules ?????????

if not then flash that full thunderzap kernel zip

Hi, Any updates?? What things are working? Also Can you port msm_fb/vidc and audio driver from jb_2.6... msm_fb is needed to boot with stock cm display-caf and vidc driver is needed to build media-caf
[Sony Xperia L] varun.chitre15:
Hi,

Everything is working fine just with some minor Framebuffer issues where LCD sometimes doesn't get updated. And no, there is no need of porting anything, the kernel itself as a whole is purely based on latest kk-2.7 Kitkat branch.

After I stabilize it to a max extent we don't have to worry much about kernel compatibility for next 2-3 android version updates:)

And yes with those new CAF kernel sources, everything from hardware/qcom/* compiles+works very nicely.

Regards.
[Sony Xperia L] hashroot:
Cool:good:, Did you try building CM? And is this repo fully working/updated?

Hi freakzapster,

the kernel that I flashed is the ThunderZap-3.1-Ultra.zip (the complete ones)...

my wifi is working, BUT wifi tethering isnt working... the clients are stucked in the "getting ip address" message,

the password is ok...(123) so the problem is in the wifi tethering... because i used it before without problems..
[Sony Xperia L] varun.chitre15:
ThunderZap 4.0 is almost done. Both KK & JB!

The KitKat version currently & temporarily has been rebased to use the stock sources as I haven't managed to fix the display issues with CAF yet.

One that is fixed TZ 4.0 with CAF will be re-released.

The amount of changes the kernel has gone from 3.1==>4.0 is way too much and there is high chance someone may face any issues even though I haven't faced any. And for this sake, just like v3.0 I am introducing beta testing program for v4.0 for up to 4 testers.

Interested people can pm me but only 4. After the number is reached this post will be edited indicating closure for the tester intakes.

Edit: Beta testing closed

Regards
[Sony Xperia L] baraozemo:
Here more details about the wifi tethering problem.

note: before I unlock my bootloader, the wifi tethering was working fine...

- I flashed the kernel (thunderzap 3.1)

- WIFI connection with my router is OK

- the WIFI Tethering (without password) works OK... clients connect normal.

BUT

- WIFI Tethering with password (012345678) , IT FAILS.. all clients are stuck in "getting ip address" and never connects.

but I I change the cliente to connect using "static ip" + password, it connects OK.

Now the problem is to discover why dhcp stop working in XL while using wifi tethering..

any help for this?
[Sony Xperia L] varun.chitre15:
ThunderZap 4.0 will be released on Feb 27 :)
[Sony Xperia L] arjit mehra:
Awesome! :D
[Sony Xperia L] Navneet Suresh:

Awesome waiting for it BTW are you gonna add TWRP? or any other special teasers other than posted before ?
[Sony Xperia L] akthakur84:
Me Too facing the same problem..

But when I remove the security from wifi tethering settings, It works fine...

The problem may be in the kernel sources as SONY has not released 15.3.A.1.14 sources....
[Sony Xperia L] varun.chitre15:
I can't reproduce this.

I tried WiFi hotspot with password and two of my devices can connect without any issues.

Can you collect a dmesg and send me instantly after it fails for you i.e about 9-10 seconds after any of your device gets stuck on obtaining IP address.
[Sony Xperia L] baraozemo:
Hi Varun,

here my dumps... (NOW, DMESG LOG ATTACHED)

[Sony Xperia L] saurabh007:

[Sony Xperia L] varun.chitre15:
There is a small change.

I left one part of optimization from Kitkat kernel. JB kernel is all-stable.

And so kernel won't be released tomorrow. I don't provide a further estimate but I promise it will be done in no time.

The beta testing reviews were damn amazing

Time for the update!

After more than 2 months of work I have something to be released to the public and to be proud of. This release is very special for me because with this I have stepped into what we call as 'original development' by writing

two new drivers

from scratch viz ThunderSonic Sound Engine and Charger current control. I have worked literally hours on this.

For me, this release is biggest ever not only for this device but among all of the devices I developed in the past including Samsung Galaxy S Advance where it ruled the forum for the time it was supported by me.

Let us proceed to the humongous changelog

Changelog-

Download: http://d-h.st/3G6 [32.38 MB]

Wonder why it is so big in size?? You will know :) Just download and flash it off ;)

Please wait for my next post which will include all the instructions on how to use the ThunderSonic sound boost engine and Charger control

To those who flashed the kernel, just put the below file in /system/etc with all permissions

https://www.dropbox.com/s/4j771f7tatcrbii/sysinit.sh

And delete the same file from /system/etc/init.d

I will update the zip tomorrow with this change.

This is necessary and everyone must do this who have flashed the kernel
[Sony Xperia L] mchauhan:
Huge Update

Update is Huge ii size and changes.. Thanks for your great work varun.

Installer and new logo are nice.

Initial Impression is awesome. GPU and CPU overclocking limits are good and New Inteli Thermal also looks nice.

How to use new Sound and Charger control ?

Also, noticed just a small thing. As soon as second core goes offline my GPU reaches to it's max frequency and stays there for all the time.:confused::confused:
[Sony Xperia L] varun.chitre15:
Antutu scores not much important :)

And yes the clock mismatch is due to kernel. Cannot be called a bug because now the phone's rtc i.e hardware clock is being used to read the time. Just set the time manually and you are good to go

I will write more about this when I am on pc.
[Sony Xperia L] varun.chitre15:
Sound and charger control guide should be here in next hour.

Make sure you did what I said about sysinit.sh in previous post. It's important

Regarding GPU, that's fine. It won't go to lower frequency unless it finishes all the load it has. Not a thing to worry about tbh.

Hi Varun, i'm on omni alpha 2 right now....after installing TZ 4 with all default settings (yes i did checked Kitkat) after reboot its stuck on TZ logo....and cant go into recovery as well.
[Sony Xperia L] chongns:
sorry to ask, how long should it take to bootup, i'm on stock rom.

PS: i have waited about 5 min, it still on the Tz logo:(

edit: stock .14, flash from twrp, no wipe
[Sony Xperia L] varun.chitre15:
Ah Omni!

I knew this would happen. It's because Omni uses some extra stuff in ramdisk. It is not possible to support every ROM because they have their respective changes in their ramdisks. And currently the ramdisk is of CM11

I have a good idea in how to support EVERY Kitkat ROM. I will do it in ThunderZap 4.1.

For now, you can flash cm11 to use this kernel.

What firmware? It has been confirmed that it works on .26 and .14 firmware for Jellybean
[Sony Xperia L] saurabh007:
I set the clock manually, still it is not updating.. Don't know why
[Sony Xperia L] Dev.Katalyst:
Thanks varun. I'll wait for 4.1

as long as titanium backup is not working in Cm11, i'll stick to omni.

Why is non-OC version now needed?

The second core overriding issue is fixed and there shouldn't be any problem
