I have a device labelled Superpad VI. everything was okay but when i tried firmware update, its wifi stopped working and started giving "error" when i try to turn it on. Now I have just figured out that the original superpad VI has ralink wifi chipset whereas this device has realtek rtl8188cus chipset. so when i try to install superpad VI firmware, everything else works but wifi doesn't. Now how do I need to install the drivers for wifi? I have found the Linux/Android drivers from Realtek website but they need to be compiled. I know nothing about compiling/programming and Linux itself.
The un-compiled drivers can be found here (under rtl8188cus) [URL] ....
I am trying to compile a WiFi driver (ath6kl) for my Sony Xperia E (Android version: 4.1.1, compilation: 11.3.A.0.47). I have downloaded the source code for compilation 11.3.A.0.47 from here: developer.sonymobile.com/downloads/xperia-open-source-archives/open-source-archive-for-build-11-3-a-0-47
I have compiled required kernel modules (cfg80211 and ath6kl_sdio), but I have encountered some problems during this proccess. I don't understand why on my android device (in /system/lib/modules/ath6kl) there are two modules: ath6kl_sdio.ko and cfg80211.ko (first one depends on the second one). But when I look at my sources, I see the following module dependencies for ath6kl: ath6kl_sdio -> ath6kl_core -> cfg80211. So there are 3 modules instead of 2. Anyway, after some modification (I merged ath6kl_core and ath6kl_sdio into one module) I managed to compile ath6kl.
I have replaced compiled modules in /system/lib/modules/ath6kl on my android device, then rebooted and I got the following error:
<4>[ 23.055226] ath6kl_sdio: disagrees about version of symbol cfg80211_sched_scan_results <4>[ 23.055251] ath6kl_sdio: Unknown symbol cfg80211_sched_scan_results (err -22)
I am very desperate cause I want to modify this driver (to be able to calculate some network statistics) but I cannot load modules at all so I am stuck.
I'm tinkering with building and installing Android from source. Basically I've got it down fairly well, but I seem to have run into a bit of a problem with the wlan module, probably from HTC.
Having pulled the 2.6.27 kernel sources and built that with a .config pulled from the phone, and using that as the kernel image instead of the prebuilt one, I get the following wifi failure message in dmesg:
wlan: version magic '2.6.27-00205-gf2dabc0 preempt mod_unload ARMv6 ' should be '2.6.27-00392-g8312baf preempt mod_unload ARMv6 '
probably because the .config I pulled from the phone has:
So I rebuilt with the '00205' localversion and now I get in dmesg:
[61.122497] wlan: Unknown symbol trout_pwrsink_set
but trout_pwrsink_set was changed to htc_pwrsave_set way back in February:
[ARM]: trout: Switch from trout_pwrsink -> htc_pwrsink 33/8933/1 http://android.git.kernel.org/?p=kernel/msm.git;a=commitdiff;h=44a01f...
I'm clearly getting an obsolete wlan module somehow, Any ideas for how I can get a wlan module that goes with the '00392' kernel would be appreciated.
Unable to install MODULE, I have a problem regarding my A13 android tablet device. It doesn't matter if I will post the brand name of my tablet or whatever because what I only wanted to fix is this. When I follow every instruction written at this link, and following instructions 1-7, after reaching step 5 execute run.bat. It displays the following image I screen captured. (And my tablet doesn't reboot, it's the sign that the computer can't access my tablet.
Obviously, my tablet is connected to the computer via USB cable after running the run.bat as administrator.But what is the problem why it is happening to me. (Additional information: I already installed and followed this instruction on this same device with no error at all. But why does it happened to me even I installed this with success before. I don't change any system file on my tablet before, and I don't know because,I didn't change any file or modify file neither on my tablet nor from my PC.)
<3>[ 154.264768] bcm4329: version magic '188.8.131.52-cyanogenmod-g1ad182f preempt mod_unload ARMv7 ' should be '184.108.40.206-cyanogenmod-g704f542 preempt mod_unload ARMv7 '
I've successfully built the samsung-kernel-crespo kernel from the cyanogenmod git. I unpacked a working ramdisk from a nightly and repacked it with my kernel, when i try to load the module i get the above error, The "extraversion" info that in the "about phone" tab in sittings is 220.127.116.11-cyanogenmod-g704f542, as well as the version of the modules. but for some reason the kernel is looking for that 'g1ad182f ' instead.
I loaded the module via fastboot boot boot.img and i didnt full on flash it to the phone. I backed up the working kernel module and put the new one in /system/lib/modules, rebooted the kernel and the wifi is still giving me an error.
If i try to manually insmod the module and it hangs, if i use modprobe then lsmod it says its "loading" but never loads.
the phone im working on is a nexus s if that matters.
I have a rooted Iocean G7. I wanted to install the framework module with the Xposed installer app. This was no success, I got a bootloop. After this I contacted Iocean, and I have flashed my phone with the computer. It works fine now, as it should.
how can I install the framework module without getting a bootloop or other problems?
If a kernel does not have the Advanced Routing feature (which is needed for VPNC widget - Cisco VPN) is it possible to add this via module like tun.ko module? The Adv. Routing is not needed for connecting but the connection is soon lost.
Will toggling Wi-Fi on and off drain your battery? I'm asking this because I read:
Essentially, you want your Wi-Fi sleep policy to be "Never" because when the Wi-Fi sleep policy is "Always," your phone searches for Wi-Fi more often and that drains battery (I think that's what it is saying).
At the moment, I toggle the W-Fi on every time I'm using it and off as soon as I'm done using it in an attempt to save battery. I'm not sure if this actually works or it's actually draining my battery because it would search for Wi-Fi every time I toggle it on.
On my Samsung Galaxy S4, I can't find Wi-Fi sleep policy as mentioned in the article, but I found "Keep Wi-Fi on during sleep." Am I supposed to set this setting as "Always" to save battery life?
I toggle Air View and Smart Gestures on a frequent basis as well--not sure if I should do that too.
I'm not technically inclined to develop a xposed module, but was using the 8sms app. I loved it since it mixes stock sms with cyanogenmod, but doesn't display FB contact pictures , only googles or contacts on your phone who you've added a picture for. Is there any way a xposed module could be developed to enable 8sms to pull contact pictures from fb? Not necessarily a request as far as throwing it out there and gauging community feedback (although, yeah, this would free many of us from samsungs sms app and make 8sms more appealing). What do you think? Is this possible to do?
I should probably add I'm on android 4.2.2, stock Galaxy s4 for t-mobile and rooted. And yes, I'd flash cyanogenmod but I do need t-mobiles wifi calling do to zero coverage at home.

I have disassembled my Z930 Tab.I found that my WiFi chip is from RealTek (8188CTV or 8188CIV, Can't make out the model name, too small) whereas my tab has some HTC port rom which has the driver for Broadcom's chipset. I found the driver, its RTL8188CUS. But I don't know how to compile it for Android. uninstall Broadcomm's driver and install RealTek's. My custom ROM is running on JB.
I have bought S3 i9300 few days ago.Its updated to Android 4,.1 and it is rooted.Screen uses more than 50% of battery but the brightness is at low.I am facing is the WiFi connectivity , when I disconnect the WiFi it remains as and does not work at all.I think the WiFi problem is due to old kernal but I don't know how to update Kernal ?
how to change the icon of its battery, WiFi and signal bar. I was able to successfully root the phone..I wanted the phone to look original by changing those icons. Even if i try to apply different themes those icons wont change. And another problem is Phone Coverage Signal weak or lost, another phone can receive 50% or full coverage signal.
Ok I'll admit it I've been watching Engadget's live blog of the iPhone 4 debut. Something interesting stuck out at me however. In one of the keynote slides, Jobs pointed out the iPhone actually gets better battery life while on WiFi vs 3G. Normally I switch WiFi off when I'm not using data, syncing will still access 3G when I'm at home and I'll do occasional browsing at home as well. Would I be better off accessing data using WiFi when available rather than 3G? I guess a better way to pose the question is, does the 3G radio use more power then WiFi?
I am currently making an application that's to work as auto-theft.The user whose mobile is stolen sends an sms to his phone and it's intercepted by the application installed in the phone.According to the format and instructions the phone performs the task.I am making a module to hide the contacts on a particular instruction.How do I go about it.I have worked on inserting and updating contacts but how do I hide them, such that they are not visible in the native contacts app.They should become visible when the user sends another instruction.that means they are not to be deleted.and I had another query related to this.how do we delete a contact?
I am trying to make a DRM module downloadable on Android.
I've already applied our modules in embedded system. To apply a DRM module in Android, I made it as a CPM Plug-in of OpenCore and added its uuid in pvplayer.cfg. After applying, DRM-protected music contents can be played in Music Application of Android.
I've planning to make the module downloadable because I want that drm- protected music contents can be played in not only new android phones but existing android phones, after a user downloads and installs it in their phones. BUT, we have a lot of difficulties in finding method.
If anyone knows any method, could you tell me? I have another question. When myAppl.apk is installed in Android, I want a .cfg file written in /system/etc. Is it possible?
For common linux, we provide a kernel driver and also a X11 module for our device. Since Android use the same linux kernel, I guess our kernel driver should work... Well, how about X11 module? does Android includes Xorg ? If not, what's target we need to do for our original X11 module/driver?
I'm porting android to Devkit8000 which is a BeagleBoard clone. I have a GPS module connected on /dev/ttyS0. I could successfully get NMEA output when writing "cat /dev/ttyS0" in the terminal emulator.
I want to know how to let android know that there is a GPS module on /dev/ttyS0 and it is outputting NMEA standard? To be able to use the android.location class with it! or test it with any GPS app in the store!
Is there something to edit in the android's source? adding driver for example, writing a code with android-ndk or what?
i'm a computer forensics student who's trying to explore android forensic possibilities. I have compiled a module for testing devices (i have access to a Samsung S2 and a Galaxy Nexus running 4.1 and 4.0 respectively) in which i want to insert the module into the phone (i.e. insmod module.ko).
My problem is, i'm always faced with the problem of "insmod invalid module format" everytime i try to insert the module into the phone. I know that i can correct this by reflecting the appropriate kernel version in the vermagic string when i compile my module but i wanna find a generic way to do this; in other words, i wanna find a way to bypass this kernel version checking everytime i try to insert the module.
I've come across insmod having the -f flag as stated here (this would theoretically bypass the kernel version checking and i wanna verify this theory) insmod.
As an experiment I set all my internet apps - backup assistant, gmail, people, calendar, news, weather, amazon, stocks, facebook, etc, etc, ETC, to not automatically update, sync, refresh or do anything on the internet without my say-so. I then turned off my phone, put a full charge on it and turned it back on again to reset the timer for Settings > About phone > Battery > Battery use. For the next 6 hours I made a few phone calls while I was not in range of any wifi; I used a few local (non-internet) apps like calculator and stopwatch and camera but I did NOT use any internet apps. At the end of that time "battery use" showed Wi-Fi at 30%, Cell standby at 28% and voice calls at 6%. So why is WiFi so high? Is that just from some "keep alive" or beacon or polling feature? Or is there some app or process I don't know about using the WiFi connection, and how do I tell?
