I think Wifi Signal Drop when we are using with SOD patch.

with Kernel r10 , I have good wifi signal :) , then now i upgrade kernel r12 with SOD patch Wifi signal Drop (reduce) .

I think this is common issue.

Can you fix this problem ?
[Samsung Galaxy Player 4.0, 5.0] Entropy512:
Hmm... Haven't had any wifi problems on the US version with the SOD patch, and no one has had wifi problems due to it on Nexus S, Infuse, I9000, Captivate, I9100, or I777 (AT&T GSII).
[Samsung Galaxy Player 4.0, 5.0] kiwijunglist:
Any chance to add underclock to 50,000 Mhz if you think it is safe?

Anyone done any tests on voltages to see how low we can go safely, I've currently set

10000 -25

800 -50

400 -50

200 -50

100 -50

but i think that is very conservative. To test a voltagei think the best way is to set the max/min cpu to the same eg. if you wanna test 400 set max=400,min=400 then run stress test at desired voltage.
[Samsung Galaxy Player 4.0, 5.0] noisyfox:
I have wifi problem too... My wifi signal drops. I have a wireless router right next to me, but i still can't have full wifi signal.

View attachment 885690

See these two pictures.

The one above is using r10 kernel and another one is using r12.

I didn't move the g70, just put it next to my computer and using adb to reboot download.

I hope it can have a better wifi signal with kernel r13.

THX.
[Samsung Galaxy Player 4.0, 5.0] marcusmarcus:
Mine is set as follows:

12000 -75

10000 -100

800 -100

400 -100

200 -100

100 -150

So far it has been stable, Have not tried to set it any lower yet.
[Samsung Galaxy Player 4.0, 5.0] Entropy512:
Safe - maybe. But almost surely pointless. The conventional "power consumption is a linear function of clock speed" rule becomes invalid when clock gating (basic idle states) comes into play, and completely goes out the window when power gating (deeper idle states) are available. In these cases, if two clock speeds use the same core voltage, or even reasonably close core voltages, the lower clock speed will actually use MORE power due to not being able to enter deep idle states where core power gets shut off.

This is why, for example, the minimum of the Exynos in the GSII is 200 MHz and 100 MHz is pointless (never saved power for me, and in fact used more power in a few situations), and why the GNex minimum is 350 MHz.

There is no "we" when talking about voltage limits - every device is different. If all devices supported lower voltages universally, they would be sold that way.
[Samsung Galaxy Player 4.0, 5.0] kiwijunglist:
I imagine the voltage would be set to accommodate 99.9% of the cpu inside the galaxy tablet, so they only have a return rate of 1 in 1000 due to instability of cpu caused by insufficient voltage. This may even be higher, eg. 99.98 1 in 5000. If we lower this to an acceptable 90% margin then we can post a suggested undervolting guideline, this is why I ask what other users are running.

Also I thought that typically

power consumption = constant x voltage squared x cpu freq

So if above is true the cpu at 100mhz will use less power than 200mhz even at the same voltage. The same would be true of 50mhz vs 100mhz, if the tablet's idle tasks can be performed at 50mhz (Given that we don't have to run a 3g/2g connection while the tablet is asleep, it can probably run at 50mhz easily and will use less standby power).
[Samsung Galaxy Player 4.0, 5.0] Entropy512:
So... you didn't read anything I wrote about idle states and clock gating/power gating. That general rule of thumb has been invalid for ages - any modern CPU *at a minimum* shuts off the clock when the CPU is idle - so 50% duty cycle at 100 MHz uses about the same power as 100% duty cycle at 50 MHz. Almost all CPUs support even deeper idle states where the CPU power is shut off during idle, which not only stops the dynamic power consumption, but also stops static power consumption - at low speeds like this, static power consumption (not dependent on clock) is significant. So spending half the time in deepidle at 100 MHz uses less power then spending no time in deepidle at 50 MHz.

(all modern CPUs have the ability to enter idle states of the CPU even if the system isn't being put into deep sleep)
[Samsung Galaxy Player 4.0, 5.0] onurdndar:
Has anyone tried the CIFS support? Is it supposed to work out of the box? When I was on Froyo stock rom, I used CIFS Manager with modules compiled for the Galaxy S here : http://xdaforums.com/showthread.php?t=761414. They don't work with the new kernels, and I couldn't get it to work any other way.
[Samsung Galaxy Player 4.0, 5.0] rumirand:
Bump to r13.

- Added charginghacks from Entropy512's kernel.

Please test if wifi signal is ok.
[Samsung Galaxy Player 4.0, 5.0] eng_matt:
Hii rumirand , your work great , thanks for everything , I want to something for you :) if possibble .

Can you add r13 kernel without SoD patch. ?

I want to test it. wireless signal drop issue. Thanks.
[Samsung Galaxy Player 4.0, 5.0] rumirand:
The patch shouldn't affect wifi signal. The dhd.ko module isn't recompiled. Maybe it has relation with switching the source code to US.
[Samsung Galaxy Player 4.0, 5.0] Entropy512:
And also - even if reported signal varies, is there actually any performance change?

The BCM4329 and BCM4330 seem to be wildly inconsistent in terms of wifi signal strength reporting. I'm also 90% certain the signal reporting is determined by the wifi firmware (in /system/etc) not the kernel.

CWM

AM I missing something here, but I'm seeing CWM as an install option. I can't find anything on how to install CWM on this device 5.0. Any help is greatly appreciated.
[Samsung Galaxy Player 4.0, 5.0] Entropy512:
There's a reason he also has Odin-flashable tar downloads... For those like you still on the stock kernel.
[Samsung Galaxy Player 4.0, 5.0] jayhammy:
Yes, I see that. But there's obviously a way to install CWM on this device as there are builds for it. But I haven't seen any way to get CWM on the Player 5.0.
[Samsung Galaxy Player 4.0, 5.0] :
I could be mistaken but I think what Entrophy512 is trying to say is that in this device the way to install CWM is to flash the kernel. CWM is in the initramfs that's packed into the kernel. So, flashing the kernel has the secondary effect of installing CWM. ;)
[Samsung Galaxy Player 4.0, 5.0] marcusmarcus:
You have to use Odin to install this the first time. That will get CWM on the device for use for any future updates.
[Samsung Galaxy Player 4.0, 5.0] Entropy512:
Yup. CWM is included within custom kernels on nearly all Samsung devices. (Tablets, the Nexus series, and Tegra/Snapdragon based devices are the main exceptions.
[Samsung Galaxy Player 4.0, 5.0] jayhammy:
Awesome. Thanks, guys!
[Samsung Galaxy Player 4.0, 5.0] pitbull84evil:

[Samsung Galaxy Player 4.0, 5.0] kfirbep:
to install the kernels i need to falsh it with odin and install it from recovery?
[Samsung Galaxy Player 4.0, 5.0] rumirand:
Flash with odin OR install with CWM.

The first time you need to flash it with odin.
[Samsung Galaxy Player 4.0, 5.0] rumirand:
Will see what I can do.

boot loop

Im stuck in a boot loop and cant get out. I have tried reflashing the rom and also the stock but both keep looping. what do I do?

Well I think its a boot loop it gets to end of samsung goes black and restarts. I cannot stop it.
[Samsung Galaxy Player 4.0, 5.0] rumirand:
Try wiping data and cache in recovery.
[Samsung Galaxy Player 4.0, 5.0] Samwes:
No that hasn't worked, still does the same.
[Samsung Galaxy Player 4.0, 5.0] Entropy512:
It's not a fix for "ghetto lag" - it's a ghetto fix for lag.

Full Voodoo Lagfix support includes scripts in the initramfs that automatically convert RFS to ext4 and have addons in CWM to control this process.

"ghetto lagfix" means the kernel supports ext4 partitions but you have to manually convert them.
[Samsung Galaxy Player 4.0, 5.0] rumirand:
Just a little update. r14 released.

Changed overclock patch (now Entropy512 based).
[Samsung Galaxy Player 4.0, 5.0] Samwes:
Is it possible to just reset everything, get it to put stock kernel back on or even just unroot in recovery mode?

Can you turn device off while in boot loop? I cannot find out anything about this elsewhere
[Samsung Galaxy Player 4.0, 5.0] rumirand:
You can enter in download mode and reflash stock firmware. Then, enter in recovery mode and wipe data and cache.

You can't easily turn off your device if it's bootlooping.

[Kindle Fire General] NewKindleUser:
Hi,

Could REALLY do with some help here ... starting to pull my hair out. Rooted my KF with the steps from http://xdaforums.com/showthread.php?t=1410766. Got through the root and the process hung on the recovery install.

Now my KF just shows the Kindlefire booting screen. I've tried loads of edits to the drivers re-installed many times, etc ..

In device manager, I see the device as Android Phone / Android Composite ADB Interface. The problem is that the device status always stays at: This device cannot start. (Code 10).

adb returns nothing. It's like I can't connect to the device at all.

Can ayone please help?
[Kindle Fire General] movieaddict:
i think its stuck in fast boot??
[Kindle Fire General] NewKindleUser:
Tried the various restarts as suggested in the thread. No luck.

Device Manager still has a problem with the device. KFU can't connect or see the device.

I've tried re-installing the drivers several times, but always get the same result. Searched the threads for a similiar problem and it seems most issues are when people get to the the Yellow Triangle page. I'm not getting that far.

Seems to me to be a driver problem, but I can't trick Windows into figured it out.

[Kindle Fire General] b63:
some more information would be helpful

os/bit of computer ?

have you tried to remove the old drivers ?

http://support.microsoft.com/kb/315539/en-us

which drivers have you used ?

in the meantime there is a new kfu available 0.9.2 which has a new driver installer.

http://xdaforums.com/showthread.php?t=1399889

would download it, extract to c:\ and rename to "kfu" cause it don't likes spaces in the pathname - sometimes. run install_drivers.bat

then run the utility with run.bat and try to set bootmode to normal (option 1)

the 3 status messages from kfu may also be helpful for us

Thanks for direction and feedback.

I had previously installed the drivers with kfu 0.8 and 0.9.1.

I'm using Win7 x64 running in a VM (I have a MAC) as well as WinXP 32.

I've downloaded and installed the drivers from the latest KFU. When I connect the KF, it appears under the USB Controllers Group in Device Manager with a Yellow Warning Triangle. KFU cannot connect:

ADB Status: Offline

ADB Rooted: No

Boot Status: Unknown

The WinXp isn't on the MAC. But the Win7 one is.

I'll try the MAC port as well.
[Kindle Fire General] b63:
then you have 2 options:

1. try the mac port

2. use winxp machine and be prepared for a little hassle with the drivers

good luck !
[Kindle Fire General] skourg3:
I've seen it show up as unknown USB device before. You can't install the drivers when it's in this state. Usually doing a hard reset on the device (hold power for ~20 seconds to turn off then turn it back on) fixes the device and it will show up as either Amazon Kindle with a yellow exclamation (without drivers) or as ADB Device or some such if you do have the drivers. If it shows up as Amazon Kindle without drivers, install them (right click, update drivers, browse your pc, point it to the drivers folder inside KFU). You should then be able to run KFU option 1 and select Bootmode Normal.

If you can't get that to work, download the android SDK on your Mac, use the SDK manager to download the Android platform-tools, open up a Terminal, cd to that platform-tools directory, and run

./fastboot -i 0x1949 oem idme bootmode normal

Which should get you back in normal mode.
[Kindle Fire General] iconoclastic:
I registered just to say that I thought I had bricked my KF (it was just stuck in fast-boot). I tried all of the driver fix stuff but the Kindle Fire Utility still said that no Kindle could be found. I tried your suggestion, skourg3, and it worked perfectly. (slight addendum for the uninitiated: the command is fastboot -i 0x1949 oem idme bootmode normal).

[Samsung Galaxy Nexus] rickhuizinga:
I've had this happen to me about once a day.

I noticed something unusual while travelling for the holidays: I did not experience a single reboot or hard freeze while having a Rogers SIM card in my phone while in Canada for a week.

Within 15 minutes of returning to the US and inserting my T-Mobile SIM card I had another hard freeze.

This seems pretty systematic, over 8 days with a T-Mobile SIM card I've had about one hard freeze per 24 hours. Over 7 days with a Rogers SIM card, not a single freeze or reboot.

Happens to mine as well every now and then. Today just after I had started it and it was lying on my desk.

[Samsung Galaxy Nexus] Xaelius:
I dont have one myself but have been flashing and re-flashing on my NS4G since the first SDK port of ICS. My own experience and observation has been as follows: Once the official sources were release and the initial source builds began coming out, there was a problem with random reboots and as things were tweaked and adjusted they became less frequent then more frequent again and eventually in the right ROM/kernel combinations have almost entirely ceased. Its most likely a software glitch and until an update or you flash something custom it isnt likely to go away no matter how many times you exchange it....just my thoughts and opinion on it.

Please don't flame this!

But the speed at which new apps are being published.. marketplace is sure going the good way
[Windows Phone 7 General] ohgood:
i'm not flaming... your article has no mention of wp7 at all (as you stated), and that puts wp7's presence in perspective for calendar year 2011. A quick search of the comments also showed no references to "wp7" for me. Maybe the fans haven't woken up yet for commenting, or don't care about the 'year in review' or overview, if you will.

A more focused user-based collective opinion about wp7's success or lack of it via adoption numbers is on slashdot, this morning:

http://mobile.slashdot.org/story/11...el-on-why-windows-phone-still-hasnt-taken-off

there are the usual trolls and fans, but the consensus is what we've all seen debated here on xda before. give the comments a read after the 'article' and you may get some more insight as to why there was no mention of wp7 in your linked article.

happy early new year ! :-)
[Windows Phone 7 General] vetvito:
To be fair, he said "no mention of WP7". ;)
[Windows Phone 7 General] drupad2drupad:
LOL why did I just know you guys will comment ;)

Yeah, the only reason to share the video was to show that even though they accept the fact or millions of apps on different platforms, they do acknowledge like most of us that daily we only need 3 apps or so. That is what I mentioned somewhere else in the forum saying - after I moved from android, I thought with only a few thousand apps I will never find apps I used on android, but to my surprise I found everything apart from SMSbackup+ and Titanium back up. But turns out we dont have back up facility yet and hence no apps of that kind. Again my 'need' of app on day to day basis was very little so I might have found the transition easier.
[Windows Phone 7 General] svtfmook:
this i feel is also their downfall, most apps are crap. there is like 25 kama sutra apps, but only 2 google talk apps...

how many HD babe apps does one market place need anyhow?
[Windows Phone 7 General] pillsburydoughman:
The quality of apps is an issue though. My nephews got an ipod touchand frankly i was shocked how lame the games on windows phone were compared to ios ones. I think developers need to concentrate on making quality apps.
[Windows Phone 7 General] RoboDad:
You keep saying this, but it is simply not true. WP7 just passed the 45000 app mark a couple of weeks ago. And, depending on which site you query, the current total is somewhere between 47000 and 50000.
[Windows Phone 7 General] drupad2drupad:
Lol sorry I keep doing that I know! I think it follows some tweet prediction when it hit 40,000 in November saying with Lumia's launch around end of Dec-early weeks of Jan it will steep to 75,000 (speculation, I know!). But again I think pocketnow tweeted recently of it crossing 50,000 mark this month? Not sure :s
[Windows Phone 7 General] svtfmook:
i would rather have 500 QUALITY apps over the 50,000 HD Babes and kama sutra apps that the marketplace now has.

devs are waay too interested in making a quick buck with tons of low quality simpleton apps that took them 1 day to develop that they throw on the market for 99cents. when they could spend some time on making 1 really good app and selling it for $4.99 and they would probably make a lot more money. but instead, they are just looking for a quick buck.

huge problem with windows marketplace. they need to do some app house cleaning instead of just inviting anyone with $99 to put whatever app they want on the market. sure it drives up app numbers, but seriously attracts crappy apps.

look how the itunes app store was. you had to apply for an sdk license, only so many were given out and apps had to be approved. they still had a huge increase in app numbers, but the apps were a lot better quality.
[Windows Phone 7 General] doministry:

It's the lack of important ones.
