Exactly what I thought when I had the i9300t everything worked exactly like the i9300 I was able to intexchange modem roms kernel etc.... now we have users with i9305t which flashed i9305 Rom and kernel with no problem at all. I dont see why it wouldn't work.

And the hardware is actually the same I am pretty sure of it.

Now you can modify and enhance your cpu and gpu and other tweaks best of to know what u are doin before playing.

SO THERE YOU HAVE IT WORKING ON I9305T AND I9305 JUST LIKE I THOUGHT

I cant seem to find anywhere to changed those settings, they are certainly not where they were on my SG2 custom roms.

LOL yes i know you need 3rd party software to do this now. I think Andreilux soon is going to make an application that goes with his kernel that will be able to do the tweaks that his kernel allows, for instance setcpu will allow you to overclock CPU i havent tested Stweaks yet but that allows GPU and cpu tweaks and much more, the reason custom roms have it is they pre-install it with the rom

I'm pretty interested in the audio tweaks:
Gökhan Moral's port of Voodoo Sound implemented. Currently no configuration interface is available, so if you wish to play with the settings, refer to the sysfs interfaces in /sys/class/misc/scoobydoo_sound/ . If you wish to change the device name, you must do echo 0 > /sys/class/misc/scoobydoo_sound_control/enable , followed by an echo output to the same file with the target device driver name. You can use this to change the device path to /sys/class/misc/voodoo_sound/ and sub-sequentially make a certain configuration application work. Please do not ask me for support on the latter. You can disable the sound modifications completely by the same method, by of course not re-enabling it afterwards.

Is there a guide as to how to configure it?
Really hoping the audio would improve on this device.
Thanks for the kernel!! :good:

You think telstra had their own version developed? I dont think so. I installed the optus rom on my telstra phone and it worked flawless. Unless there is something very minor....
Edit: Now installed on my 9305T. Never used a custom kernal without having a whole new rom also. So not sure what its actually meant to be doing....

Confirmed working on 9305T :)

Edit.

Scratch that, I just had a brain failure moment, should've got more sleep last night. The differences would probably be in regards to 3G frequencies. Lte hardware would be the same. I see no reason why the kernel wouldnt work exactly the same as standard I9305.

In hobart im getting 8MB/s by 2.2MB/s


I'' go for a drive into Hobart and do some tests now on the Kernel and report back
as 4g dont reach me atm
but i dont know what i should be expecting

I took a backup of boot.img on my 9305T before flashing... let me know if this would help narcarsiss

Just confirmed that mobile data still works for need on i9305T, I had only checked WiFi previously

I checked the 9305T sources and they are indeed different than the 9305 ones, but not in the way you'd think. I'm already compiling this kernel right now with a merge of 9300 and N7100 sources and didn't touch the 9305 ones. Anyway the defconfig doesn't differ between the two, so there is no difference in the end product. So I can confirm it works. I still find it stupid to proclaim it works and flash it on a device without prior checking of the code, in this case it worked, in 95% of other cases it doesn't. But I hope you knew the risk beforehand.

I think we all did. we just dont care that much as the phone can be brought for $380. and someone has to take all the risks blind folded.:highfive:

$380 lol where in the world are you getting your price the cheapest I see it online is around $730 Unlocked/No contract

The only difference is probably the "t" version doesn't have all the lte frequencies but only the one Telstra uses OR if not then I know Telstra got rid off the 2100mhz 3g frequency maybe it's just missing this.

Even if it's in pounds that's still $600
Still the cheapest I have ever seen for the i9305

Mines telstra phone cost me $384 on a 60$ plan (there is always a catch)



Also a side note:
After bench marking this kernel against my stock kernel phone this one is giving me in quadrant constant 200 points slower

5600 points; Stock Kernel untouched phone not Overclocked
5400 points; SS v1.1 Rom with this kernel not Overclocked

^ overclocked @ 1704Mhz i get 6600 :)

LOL OHHHHHH ye ye Ofcourse if your talking about contract, which means you are locked in.... they are not stupid by the end of the contract you definitley have paid for the phone and more

There is no way you will get one for $380 Unlocked without contract


Thats strange I get a constant 7000-7200 score on when i am over clocked @ 1704mhz and around 6000-6200 Normal

But I am on XXALI5 Base - De-bloated/Unbranded , Deodexed/Zipaligned. Not sure if that makes a difference


And since you got 200 more stock then with the custom rom I am thinking if u had the custom Rom debloated/ zipaligned/deodexed with Perseus kernel and OC 1.7ghz you will get closer to 7000 according to the scores you wrote. ;)

I only get 5000ish with stock everything straight from telstra. Waiting for a more complete rom b4 I change to it though.

we need our own general and q&a thread. I dont like the fact that we have to post in amongst i9300 threads. Can we all ask the mods this? The more of uz the better.

What we want?

Our own I9305 general thread and q&a thread or atleast our own q&a thread. Lets all msg the mods please

Hi AndreiLux,

can you compile the FM radio module as external .ko module ?

i want try to load it in the kernel and try with the app Spirit FM

or have you already tried ?

if the module compile well only in the i9300 kernel version, you can compile the i9300 version with the vermagic modified for the i9305 kernel. i want try.

    Identical kernel to the i9300 one. Only difference is:
    • CMA device memory allocation is gone as we don't need the hacks used in it for larger memory, 2GB with the default setting will suffice.
    • You apparently have no FM radio.

    The port is trivial and everything else should work flawlessly.

    Please refer to the I9300 thread for changelogs, bug-reports and other issues. Kernel itself will be posted here.

    Hello AndreiLux ,

    is this project still allive?

    I've told you guys the i9300 will always be first to get new versions since that's what I have to develop on, test, and use. Please refrain from such posts because I will update here as well (i9305 users are first in line before the 7 different Note 2 versions...). I also use the i9300 as a testbed for fast feedback in case of bugs, and that's why you people for example never get non-hotfixed versions first because things will already have been debugged on the i9300.

    So, with that in mind, uploading 30.1 now for here. Please read the changelog in the main thread.

    Basic, not very scientific UV test

    Hi Guys,

    I finished my two days of UV and non UV testing.
    TL;DR: UV seems to help a decent amount, I think it's worth the hassle.

    What did I undervolt?
    I spent weeks undervolting my CPU, GPU, internal, and memory components. I then went through each component, and used the ABB interface to see if I could further undervolt. On the CPU I could undervolt a little bit further, on the GPU and internal I could get a decent amount of extra UV, on the memory component I could gain no further UV with ABB. Please note I'm unsure about the GPU undervolting - there appears to be a bug with the GPU frequency or volt_table interfaces, more on that HERE and HERE.

    Click HERE to see my full undervolting, but for a quick idea, here are my average undervolts for each component:
    CPU: 155mV
    GPU: 147mV
    Internal: 175mV
    Memory: 150mV

    Not bad for an ASV3 chip :)

    How did I test?
    Both days I took it off the charge at midnight, and left it off the charge for the next 18 hours. Used BetterBatterStats to monitor everything, I tried to use the phone in exactly the same way both days - about 1h30m screen on time, which included about 20mins of candy crush saga, both days push syncing an exchange account from 8am - 6pm, all google services on push (google now disabled), about the same SMSs, same amount of wifi and 4G, I think I was pretty consistent.

    I wish I had more time to knock off a few more tests, but my i9505 came in, and I've already left it in the box for 2 days.. I can't resist anymore :)

    "alarm" (): 15 m 6 s  (906 s) Cnt:(c/wc/ec)5053/10/0 1.4%

    So, both days had the same:
    - Total time on
    - Screen on time
    - PowerManagerService wakelocks
    - mdm_hsic_pm0 wakelocks
    - signal variance

    The only real difference is the screen brightness, but I don't think this is enough to worry about.

    Battery level, however, the UVed config used 3.9% battery per hour, whereas the stock voltage config used 4.7% battery per hour. Over the 18 hours, this meant that with UV I had an extra 15% battery than I did with no UV.

    Caveat: I do think I used the phone slightly harder on the stock voltage test day, but only right at the end, i used google maps with GPS for about a minute, and I drove to the shops which I didn't do the day before. This may have made a % or two difference, but not 15%. To balance that a bit, I cut the test short on the second (no UV) test day, the overal % lost is probably about right.


    Hi @omniwolf,
    Thanks for sharing the profile. I tried the just the CPU and GPU settings and got a FC. Which version of the kernel are you using ? I'm using 36.2.
    Yes, this is with 36.2, but with this fix I posted to make it act like 36.3.

    Hi Andrei,
    Any chance we can get the mods from alpha26 in the i9300 kernel in this one?
    Thanks :)
    Here you go. Sorry for not keeping up to date too much but some irritating people in this section and the minuscule user-base of this device makes me a bit lazy in releasing things.
