Thanks for the new links. The link for the v02 img in the OP actually goes to those that same file (same MD5), which is actually v01 test 2. It appears that the real v02 is for 2.3.4., and is apparently not ready to be used. When the v02 link was changed in the OP, the MD5 was not, so the MD5 does not match the file that it links to.

Link in OP: http://icxperia.com/doomlord/play/cdma-dk-02/PLAY-CDMA-DooMKernel-v01-lower-test2_boot.img

MD5 for the file above: c2e649cece34e5f9c3ccdd5bd26b05d5

(same as ozzman's link)

The wifi zip should be the same.

See all the files here: http://icxperia.com/doomlord/play/cdma-dk-02/

Again, I'd stay away from the "real" v02 downloads, since they apparently have many broken features.

I just flashed v01 test2 (from the link in the OP) with Cola ROM v6 on my r800x earlier today and its been working beautifully. Games run SO much smoother than they did in ICS. ICS is simply too much for this phone if you want to play demanding games. Minecraft would stutter and skip like mad when I was running FXP142\144 and LuPuS v7 and v8. That seems to be a good ROM\Kernel combination if you absolutely need ICS, but with DoomKernel and Cola ROM with GO Launcher EX, I'm getting absolutely no performance problems in games. I have 290Mb of FREE RAM, with around 100Mb used right now... I played Minecraft for about twenty minutes, and it only hitched for a fraction of a second when the first night transition started. It was perfectly smooth!

I love ICS on my HP Touchpad, and it definitely seems to handle task managing better (smoother transitions to previously used apps with a bit less mystery involved), but for this phone a nice and light installation of GB is definitely the way to go for performance. I haven't even tried web browsing yet, but that was another area that ICS was simply too heavy, so I'm sure it will be a huge improvement with over 100Mb MORE free RAM available for the browser.

I just wish this kernel and compatible Stock-based ROMs (specifically Cola) were still being worked on. I'm sure they could be even better if they were to get some attention at least once every 6 months...
[Xperia Play Android Development] chery2k:
Okay sorry for reviving this old thread. My xperia play the R800x flashed with Doomkernel is driving me nuts with wifi. (flashed doom's wifi modules) It always disconnects every 3-4 minutes and reconnects while Im at my room and the router is located in the kitchen idk why it act likes this. Just recently I bought the GSM R800a (flashed with doomkernel) and did a side by side camparison with my r800x no wifi drops and it stays connected to my home network.:silly:

Even a fresh install of the 2.3.3 stock for the r800x gives me wifi disconnects. (The same results with Doomkernel) Is there a fix for wifi on Doomkernel's or by chance a way to boost the wifi signal? If I flash Doom's ics beta kernel on my R800x I havent experienced any wifi drops and what gives:confused:
[Xperia Play Android Development] ozzmanj1:
My friend this very reason is whybi have been nagging wedgess forbhis cdma updatevof his kernel and modules. Ibuave been having this exact same issue for many months. This is the sole reason I keep scoping out the Lupus thread every other day. For me I have to reflash the modules every couple days to get it to work for just that much longer. I even peeled off a part of the wifi sticker which is bybthe sd card. And ran a super thin wire and ran it down the side of the phone half way down the side of the phone. Hoping it would act as sort of a extended antenna. Same issues. Its not hardware its software issue. Although standing 5 feet from my wireless router I have about 3-4 bars. I did jump to 5 bars with the wire trick but still dropped. Anyways. Sorry for the long post. I'm just as frustrated as you. Been redoing wifi modules about once a week for many months now and its frustrating but I don't have the time to learn how tobfix this myself between 50 hours a week at work and kids, wife, etc.
[Xperia Play Android Development] CosmicDan:
Have you guys even tried LuPuS GB version to see if it works? This kernel is only needed for out-dated/fully-stock ROM's. There are custom GB ROM's for CDMA that should work fine.
[Xperia Play Android Development] ozzmanj1:
Yes I have tested it. the wifi modules don't work unless your wireless is on static ip. Dhcp does not work
[Xperia Play Android Development] chery2k:
Lupus gb on my r800x works except for wifi and picture taking. Video recordings works btw.

How did you get past the bootloop? Btw im on the stock 2.3.3 rom.
[Xperia Play Android Development] Schwabie64:
I never had a problem with bootloop. I'm currently running a modified version of Cola Rom, on 2.3.3. I've also used his kernel on stock and gbtweaked. Maybe try it again? I can attempt to help you in the morning if it bootloops.
[Xperia Play Android Development] chery2k:
Just this morning I flashed pax's kernel on both cola and gbtweaked rom I'm still getting bootloops (i flashed the kernel through fllashtool) Are you using pax's older kernel? Because i'm flashed his most recent kernel that he posted.

Edit: I finally just got past the bootloop. But each time I power off the device and turn it back on I get stuck in a boot loop again. So in order for me to recorrect this I had to reflash the 2.3.3 ftf file and exclude the kernel which is pax's kernel. Does anybody know how to get around this?
[Xperia Play Android Development] Schwabie64:
Hey, have you tried using the other method for flashing the kernel? And I'm on the most recent release.

Here are the steps I took.

Go into recovery, do factory reset, wipe cache, wipe dalvik cache, then go under mounts and storage and format all options (except for sdcard if you want to keep the stuff on it).

Turn off phone.

Flash 2.3.3.ftf file using flashtool.

Download Pax's newest kernel, rename to boot.img put in the platform tools folder in the SDK. open command window in the platform tools folder. connect phone in fastboot mode and run fastboot -i 0x0fce flash boot boot.img through cmd. Restart phone and it should work.

I flashed Cola rom after I did all the steps above.

Good luck!
[Xperia Play Android Development] chery2k:
Ehh i still ended with a bootloop with the instruction posted above (sorry Schwabie64) i think its a software and hardware related problem. Instead i flashed hatcyls kernel which solved my wifi problem. :)

The kernel can be found here for those looking for R8000x kernel. (Note I did used this kernel before I just wasn't sure what this is kernel is based off of I think it is R800x firmware)

This link contains a zip that has both the last release kernel and wifi modules in a zip format. Just uncompress the zip and copy the wifi modules to your sdcard, then use fastboot to flash the Doomkernel CDMA kernel to your CDMA PLAY, afterwards enter recovery and flash the wifi modules so you can use your wifi.

This link will always be here, I wll never again remove it. let me know how it goes.

just to be safe i reflashed the v1 incase for some reason that wasn't the version I grabbed, and I still couldn't get it to load into recovery. Then I tried flashing the 1.6 ghz version instead of the 2 ghz and i couldn't get that version to boot into recovery either.

i did somehow manage to get into the recovery menu by mashing home menu and search repeatedly once on the 1.6 ghz kernel. i can't seem to reproduce it though, and believe me i've tried a lot of times. i've tried long presses, short presses. from the initial vibration of the phone. right when the light turns blue, right when the kernel image shows up. back button, home button, menu button, search button, and power button in all sorts of random combinations of presses and it's only loaded into recovery once. clearly i'm doing something wrong though.
[Xperia Play Android Development] 007shark:
I can confirm not being able to get into recovery on your final kernel. I tried the back button and volume keys several times.

[Xperia Play Android Development] Mogul345:
Oh I know, I'm excited to flash your kernel this weekend! I'm looking forward to testing tethering with my TouchPad.
[Xperia Play Android Development] NeoandGeo:
Whoah. Speaking of tethering, I just tried tethering with Barnacle and it starts with an error, and also caused a BSOD of my Windows 7 machine.

Error barnacle gives is "shell-init: error retrieving current directory: getcwd: cannot access parent directories: Permission denied"

But then it says the wifi driver is loaded. My laptop was able to connect after a fresh restart, but the loading was so slow that the pages eventually timed out. I flashed your wifi zip in CWM after flashing your kernel over 007's. Wireless Tether app works fine, but I don't receive calls/texts while it runs, so I prefer to use barnacle. What do you think is causing this?
[Xperia Play Android Development] antispiral:
is there a way to flash the kernel with update.zip format or is fast boot the only way?
[Xperia Play Android Development] DooMLoRD:
Sorry mate no idea...

Nope currently no... Only fastboot...
[Xperia Play Android Development] 007shark:
I just tried barnacle and received the same error but it is still working with my windows 7 64bit machine.
[Xperia Play Android Development] Mogul345:
Just installed the kernel today and it appears to be working great. Only tweaks I've done to the CPU is to set the min frequency to it's lowest so she'll idle better.

Can't get tethering to work, at least not the way I know how. I'm running the stock 2.3.3 VZW ROM. I installed Android-Wifi-Tether 2.0.7 from Google Code. App runs and gives my Touchpad an IP address, but somehow seems to be also triggering the built-in wifi tethering app, which causes me to constantly be sent to a VZW signup page for their ridiculously overpriced tethering plans till I reboot the phone.

I thought that changing the kernel would cause the VZW internal checks to go away?
[Xperia Play Android Development] markcyst:
Autobrightness seems to be stuck "on." Unchecking the box does nothing to disable it.

Also, I can change the brightness manually, but 100% is very dim compared to stock kernel.

Any ideas? 2.3.3 by the way
[Xperia Play Android Development] antispiral:
Can this kernel be used with CM7 or do we need to use the one they provide?
[Xperia Play Android Development] NeoandGeo:
I am not able to get Wireless Tether to work either. It always takes me to the Verizon provisioning page. Using the V01 final 007s VZW based Timescape Rom. Using barnacle tether I can successfully get internet, but I get either a BSOD, or complete screen freeze on my W7 Pro laptop if there are any other open wifi networks in range that I can connect to. But I think that has more to do with the nature of ad-hoc/Windows rather than my phone or kernel.
[Xperia Play Android Development] 007shark:
Unfortunately, wireless tethering does not have to do with the kernel. The kernel simply provides the drivers that allows wifi, camera, etc to function.

The Autobrightness is tied to the kernel. Unfortunately, verizon kernel sources are still not available. This kernel is based off the 3.0.1.A.0.145 sources which did not have autobrightness options, but currently is the only kernel options we have that will work on our CDMA phones allowing overclocking and recovery.
[Xperia Play Android Development] Mogul345:
Right. I thought that the modifications that VZW made were actually in the drivers themselves, as that would be at a lower level and harder to beat.

So I guess the next thing to do is figure out how built in tethering is integrated into the system, and rip it out/disable. I have no idea where to begin on that though.
[Xperia Play Android Development] 007shark:
I was going to look into it when I find some time. It could be in one of the apks or in one of the jar files.

EDIT: The key will be finding where the browser redirect resides and back-tracing from there.

Just wondering what are the Wifi modules? I just flashed Dooms latest kernel to my VZN r800x and then saw the wifi modules, is the wifi modules for the "hopefully" working wifi tethering?
[Xperia Play Android Development] DooMLoRD:
its for using WiFi in general ;)

wifi modules are not inbuilt in kernel... they need to be flashed separately...
[Xperia Play Android Development] ozzmanj1:
Oh well just curious, as I am always learning something, have the wifi modules always had to be flashed with any previous DoomKernel? Unless I mistaken I dont recall seeing the wifi modules in prior versions of the kernel. Also I flashed the 1.6ghz kernel , running at 1.2, but where games like asphalt were buttery smooth they tend to get hiccups every now and then... any ideas?
[Xperia Play Android Development] Logseman:
Separate wifi modules have been needed in the last two versions of the kernel.
[Xperia Play Android Development] 216Monster:
I have also experienced the hiccups running fpse , FF7 on doomkernel @ 1024mhz tends to lag in spots now, where as the stock kernel @ 1024mhz ran FF7 flawless. I didnt need to overlock before for emulators :/

Doom,

I would say this kernel kicks ass nonetheless , the recovery is great and the button config works beautifully, wifi modules should kick Verizon in the balls for their little kernel stunt, great kernel for o/c on r800x ! :D Thank you for your time and efforts, I will be sending you a donation for this!
[Xperia Play Android Development] DooMLoRD:
the lags happens due to the governor in use...

i personally prefer PERFORMANCE governor during playing games... though sometimes if a sync is triggered in background then the game lags for few seconds.. bit i am ok with it as i have 100+ apps on device and few are always running in background :D
[Xperia Play Android Development] ozzmanj1:
I am using No Frills @ 1.2ghz, Governor : Performance and I/O : Noop (Dont know what I/O to use).
