thank you will and everyone else for the rom and support. and good luck with the future endeavors.
and i'm sorry if this is a bit out of sorts or just flat out wrong to post... but this thread has all the people who's opinions matter in this case.

this has been my favorite rom for quite some time... are there suggestions on where to go from here?
it will probably be months until i get the flashing itch or care enough about x or y feature, but i don't plan on changing phones anytime soon (barring accidents).... but i know i'll want some amount of change at some point.

finding a dev who's style you like and brains you trust isn't the most fun thing in the world, and neither is bug-finding on a not-quite-right rom.

again, sorry if i shouldn't post this. i assumed the thread would be buried or closed before long. call it an homage to good work if you want.. or just delete it if i'm abandoning proper decorum.
and thanks again will.

All due respect, but is this wise?


I mean, I'd want to know if my microsd card or the interface to my microsd isn't working correctly and throwing CRC errors. Further, I imagine the delay waiting for the device to complete the IO request is far greater than a simple CRC.

Also, I was trying to track down what that flag really did, and I'm rather certain the SPI/SDCC/SDHCI interfaces on the msm8974 do the CRC in hardware - it's built in to the dma engine. That's what I gather from the flags computed during the device probe here: https://github.com/willl03/kernel_samsung_hlte/blob/lp5.0/drivers/mmc/host/msm_sdcc.c


PS. Otherwise love your ROM.

If you keep regular backups (for important data), and don't suddenly lose power (battery pull), or eject the SD card before unmounting, there's little to worry about.

Why check the CRC every-friggen-time a file is accessed.
As the comment states, performance loss.

Do you check to see, exactly, how much ink is in your pen after/before every character you write? No.

Just because the ability is there, doesn't make it a necessary function.

Turns out, the change has no effect because the sdhci interfaces on the msm8974 do the crc checks automatically during the dma transfer. So, no worries.

Btw, your analogy isn't really accurate, as there is no danger to your pen running out of ink. Perhaps more relevant: I do check that I've locked my door every time I leave my house.

Thank you for this wonderful ROM! I see development has stopped some time back by reading through which sucks but is what it is because I used this ROM on my sons phone for a long time. Anyway I have a question, I'm going back to stock now from this ROM because he just gets into to much crap with a rooted phone can I just wipe ect and just install SamMobile I317UCAMA4? Im worried because I been reading about variances in bootloaders or something which I have no clue about.

Easiest way to do so would be to use Odin. You don't even need to wipe, Odin will do that for you. Just make sure that the Odin file that you flash is for your model. The bootloader and what not will be updated when you flash through Odin.

I317UCAMA4 Can anyone point me to where I can download this stock firmware? I tried from one of the most recent post but I don't have an account there. Thanks if you can.

Been meaning to post a "Thanks for All the hard work" for some time now.
Been stuck on this ROM for some time now. No worries.
Does anyone know if the ROM supports USB-OTG support?

    I am proud to present to you W03 Slim. This is a build forked off SlimKat with added features and tweaks under the hood. A huge thanks to the devs for the bases making this possible. Slim for their rom and teams like PA, AOKP, Omni, etc for their features.

    This won't be the AOSP rom with a thousand features, if that's your thing there are better alternatives. Ultimate battery, performance and reliability OUT OF THE BOX, that's the goal of the rom. When a feature gets in it's been tested to be bugless and high quality. SlimRoms has always been my favorite source so I added my layer of features and tweaks over it, made for our device and it's hardware, more than a bot building the same source for 15 different devices.

    This is just my personal variant of Slim. ALL credits to the Slim team and their Note 2 maintainer prbassplayer
    See and thank their thread
