[Desire Q&A, Help & Troubleshooting] Chromium:
Well it depends how you create the rom and what type of ROM you are creating.

If you plan to simply take an already made rom.zip, make a few little modifications, and zip it back up...it obviously isn't very hard, and likewise its not very satisfying.

If you want to compile a rom from source, then its a bit harder than the process above. To be more specific let's first talk about android versions that are officially supported by the desire: froyo, and gingerbread. Compiling roms based on those honestly isn't that hard. You just need some basic Linux/terminal knowledge. The device and kernel source is actually meant to work by default so you don't need to make any further adjustments. It as simple as opening terminal, downloading the source, and running a build command. Give it an hour (more or less depending on how food your PC is) and you should have a freshly made ROM that you built from source. Yay...some satisfaction.

The hardest thing in my opinion (I've tried all three of these) is compiling a rom based on an android version that isn't officially supported by the desire. (Ice cream sandwich or jellybean). With roms based on these android versions you will have to scour to internet for a working device, vendor and kernel tree. (Hint, hint: WoH and evervolv/nikez). Even once you get the right device tree it probably won't work. You will have to make further adjustments, and even then I'm sure you will be bombarded with build errors. But eventually once you get it to compile successfully....most satisfying thing ever :D

So yea thats my answer. Keep in mind that I've tried (and eventually succeeded) with all three of the above, and that I've got quite limited programming knowledge. (2 high school comp sci courses, where I learned some java.)

Q&A Game

Q: My kernel app tells me my min_freq is 918mhz. Why is that?

A: Its because of input boost. Your frequency will be boosted to 918mhz as soon as you touch your screen. It will be boosted for 1 second after touch. So you have smooth animations and no scrolling stutters.

Q: My device rebooted / didn woke up from deep sleep. What can I do to help you to find the cause?

A: Install "Syslog" from the Play Store and get me the "Last Kernel Log" or do it via terminal. You'll find the command one post under this.

Q: Will you add S2W/S2S again?

A: No. We're using dt2w from starosk now. If you want to use S2W with my kernel, clone my sources and add it by yourself.

Q: Why the cpu jumps to 1134mhz so ofter during idle?

A: Thats because we're using an interactive based governor. Interactive based governors jumps to hispeed_freq (1134mhz) if the load reaches 99%. Don't forget, even if you're doing nothing, you always have some background load. The lower you set your min_frequency, the faster it reaches 99% load and will jump to hispeed_freq more often.

Battery Profile:

I've made a battery profile for hot plug settings. Following is changed:

echo "20" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_0 = Threshold for cpu1 to kick in

echo "85" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_2 = Threshold for cpu2 to kick in

echo "10" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_3 = Threshold for cpu1 to kick out

echo "99" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_4 = Threshold for cpu3 to kick in

echo "45" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_5 = Threshold for cpu2 to kick out

echo "60" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_7 = Threshold for cpu3 to kick out

Most of the time you'll be running on dualcore mode (cpu0 and cpu1). If the load reaches a high level with both cores maxed out, the other cores kicks in and will go off again really quickly. The profile will be active after 90 seconds (counted from bootanimation) so your device boots up with full power first. It'll be stupid to limit it on bootup.

Balanced Profile:

echo "15" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_0

echo "35" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_2

echo "8" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_3

echo "55" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_4

echo "20" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_5

echo "40" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_7

Its a little less conservative than the battery profile and a little less aggressive than the default values. I've tried to make something in between. Try it and left a comment :)​

How to take a kernel LOG after random reboot

an easy way to get the last-kmsg is by using the script below , thanks to [MENTION=5222551]Maxr1998[/MENTION]

GetLog

the log will be saved in a folder in your sdcard called Logs

run the script and the log will be there

original post http://xdaforums.com/showpost.php?p=50436922&postcount=3234

-=-=-

Once in a while, a software bug in the kernel will cause a random reboot, so in order to help kernel developers to fix and troubleshoot the reboots, a kernel log need to be submitted to the developer for further analysis and hopefully lead to a bug fix.

Most Android Kernels have "RAM Consoles" to save the necessary kernel logs immediately after reboot in the RAM. *The users can then retrieve this RAM log on a subsequent reboot to submit to kernel developers.

[

Using ADB

]

adb shell

su

cat /proc/last_kmsg > /sdcard/last_kmsg.txt

exit

exit

adb pull /sdcard/last_kmsg.txt

open last_kmsg.txt using text editor of your choise

then copy the content

open web browser and go to pastebin.com

paste the content to pastebin.com

then send the developer the link to pastebin.com link

then send the developer the link to pastebin.com link

[

Using android terminal app

]

su

cat /proc/last_kmsg > /sdcard/last_kmsg.txt

adb pull /sdcard/last_kmsg.txt

open /sdcard/last_kmsg.txt using text app of your choise

then copy the content

open web browser and go to pastebin.com

paste the content to pastebin.com

then send the developer the link to pastebin.com link

[

Using Root Explorer / ES Explorer with Root

]

go to /proc folder

then copy last_kmsg to /sdcard/

rename last_kmsg to last_kmsg.txt

open last_kmsg.txt

here's my issue :

I've exprienced 4 reboots since I installed b39 version this afternoon.. I have attached the kmsg log ..

I installed this kernel over semaphore N4 1.7.1 without clearing any cache/dalvik cache ( cudnt find any installation instructions) .. I am on rooted stock ..

The reboots occured when i was charging the phone ..

ROM : Rooted Stock 4.3 JWR66Y

Kernel : hellscore b39 JWR build

Settings : CPU - 192 Mhz - 1242 Mhz

Governer : Intellidemand

GPU : 320 Mhz max

Undervolting : default settings
[Nexus 4 General] xanthrax:
ok then , i would suggest you to update to the latest b40 JWR

if you`re using any tweak kernel app , uninstall it first and then flash the new kernel

-=-=-

also , a 1242 MHz freq seems to be a little bit too low if you are using the phone for games , heavy games ... 1350 would be better i guess

and lets see what hellsgod says about your last_kmsg , i`m sure he will pop up in here soon :fingers-crossed:
[Nexus 4 General] bhanumagotra:
what about wiping cache/dalvik cache ... and do i have to install stock kernel first??

[Nexus 4 General] bhanumagotra:

I used to wipe before flashing the kernel... :p

[Nexus 4 General] xanthrax:

[Nexus 4 General] xanthrax:
thanks mate ! i`ll request that to a moderator even though a moderator suggested me to post it here ...

... and i chosen the first option ...
[Nexus 4 General] OhDae-su:
Ok guys, let me jump in... :)

Flashing a kernel doesn't need any wipes!

Switching custom kernels that are using anykernel updater (which Semaphore and Hellscore do) usually needs a dirty flash of the current rom...reference:

http://xdaforums.com/showpost.php?p=45374233&postcount=3186

Or, in your case you can also flash the stock kernel which gives you the same result as dirty flash. link to stock flashable kernel (the JWR66Y one):

http://xdaforums.com/showthread.php?t=2381128

Also, as [MENTION=3946657]xanthrax[/MENTION] stated disable or better uninstall any kernel tweaking apps before you flash a different kernel. And leave the kernel settings by default to see if you're getting any reboots or not. If not you can tweak it step by step. Though Hells mentioned more than once that his kernel is a flash-and-forget-one...so, usually there's no further tweaking needed. But you can :)

is 192MHz default value or have you set it?

It's still highly experimental and causes some sort of problems. Dt2W itself is unstable, and it can cause some problems on S2W, too. If there are less problems in the future, I'll test it again. Atm I don't see any benefit from it.

got same scraping noise, reboot, then surprisingly, after reboot THERE WAS NO PLAY STORE AND ES FILE EXPLORER..

About JWR and JSS

I have stock 4.3 rom and I have used Hells Core Kernel for 1 month ( used b38 and b40 ) now Im on b41 t3.

I feel really good about this kernel . However , everytime I flash the JWR version of Hells Core , there are screen tearing . So I turned on the : Disable HW overlay and Force GPU thing but it drains my battery a lot . So I try flashing JSS version and flash the JSS to JWR patch , which seems fine but there are keyboard deadlock ( there are no deadlock in b38 btw ) . Therefore , which should I flash JWR or JSS ? Cuz someone said if the developer released a JWR kernel it should be no screen tearing ....
