Does flash player work on this rom?

---

I think only opera browser

Best HC Yet
I really like this ROM. Couple of items of note that i have seen. My Wifi started to error out. I have tried fixing it, but it still just reports error. I am going to try pershoots kernel. I had issues before with Clems HC kernel. Second I tried inserting a USB disk, and the status bar says USBDisk2 inserted, but it does not appear to be mounted.

Flash

Flash works for me in Opera, but it can be a bit touchy.

---

What version of opera and flash are you using? I downloaded opera mobile 11.1 because 11.5.3 gives me problems, I'll put in a url, push enter, and whatever I type goes away it tries to load the page and just stops (like I pushed cancel on loading the page). Then I was gonna download flash 10.3 and opera started acting up made the tablet slow and had to reboot.

USB and Wifi

Does turning it off and on fix the wifi?
I'll look into using a usb disk soon.

No just keeps going into an error state. It seems to be after modifying the WPA_Supplicant with Root Explorer, is when it errors. For work, my company uses LEAP and this is the only way i know of to get it to work. I have done it a hundred times with different ROMs. For some reason unless i leave the wpa_supplicant unmodified, it goes into error. I have double checked and re-checked to see i haven't made any mistakes.

That would probably be the reason. GTabComb has a different wpa_supplicant from most ROMs, so it might not be compatible with the modification you are using. Can you give me more details on what you are doing to modify it?

---

Sure. Basically I was adding the network, from the Settings applet to use 802.x. I would then modify the supplication to look like the following with Root Explorer:
Network={
ssid=”<networkname>”
scan_ssid=1
key_mgmt=IEEE8021X
auth_alg=LEAP
eap=PEAP
identity=”<domain>\<username>”
password=”<password>”
phase2=”auth=MSCHAPV2”
}
Only after i modified it did it error. Before i modified, the entry was still there, but in the default form which didn't work.

---

Let me know if there is anything i could test for you. This is the only thing holding me back from finally being happy with an HC ROM.

Is that the entirety of your wpa_supplicant.conf file or only a fragment? Because, there are other parameters missing, and it says "Network=..." instead of "network=...". Not sure if case matters in the wpa_supplicant.conf file, but, it is something to check.
A detailed debug output would help in troubleshooting your problem. Get it by doing this in CWM:
Code:
$ [B]adb remount[/B]
$ [B]adb shell mv /system/bin/wpa_supplicant /system/bin/wpa_supplicant.bin[/B]
$ [B]adb push wpa_supplicant /system/bin/wpa_supplicant[/B]
$ [B]adb shell chown root.system /system/bin/wpa_supplicant[/B]
$ [B]adb shell chmod 755 /system/bin/wpa_supplicant[/B]
Use this shell script as the wpa_supplicant to push:
Code:
#!/system/bin/sh
exec /system/bin/wpa_supplicant.bin -ddd "[email protected]"
Collect the logs like this:
1. Power off gTab.
2. Connect USB cable.
3. Run "adb logcat -v time > logcat.txt" in a CMD.exe window.
4. Power on gTab.
5. Kill the adb logcat or shutdown tablet after WiFi has errored out.
This will collect all the logs right from the beginning.

That was just the section I edited. I don't have my cable with me so i can't run ADB right now. I did just do the same thing on Flashback and it worked, but I prefer to run GtabCombOver.

heapsize
What app can I use to change the heapsize? Also, dumb question.... What app should I use to adjust the overclocking?

Try using the wpa_supplicant binary from Flashback, then...

Just edit /system/build.prop and change dalvik.vm.heapsize.

---

awesome, thank you! I'll give that a shot. On the dev page someone there said switching those up a little was helping with overall performance so I'll give it a shot and let you guys know. Thanks again.

Actually, I'm having the same problem, and I haven't made any changes to wpa_supplicant.
The only way to get WiFi functioning again is to reboot the device. I can't turn off WiFi, because it just keeps saying "Error." I even tried going into airplane mode, but it made no difference.
In my case, the problem seems to be related to the fact that I've changed the setting for the wifi disconnect policy to "Never when plugged in." I don't remember having this problem prior to making that change.
I've changed it back to "Never" and will report on whether the problem persists.

Very unlikely.
Will need to look at logs to determine the actual cause of your problem. See post #12. Also get the kernel messages using:
Code:
C:\> [B]adb shell dmesg > dmesg.txt[/B]

Do a basic check. Look at the wpa_supplicant.conf file and see if it looks OK. As a minimum, for home networks, check that the ssid= and psk= values are correct:
Code:
C:\> [B]adb shell cat /data/misc/wifi/wpa_supplicant.conf[/B]
Again, will need to look at logs to find out what's wrong.

I haven't had time to do as you've requested. However, restoring the setting to the "default" has alleviated the problem. The device appears to be turning off WiFi after a period of time, since it's often had to reconnect after I turn the screen back on.
I'll get to the logs when I'm at my computer and have the time to wait for the wifi error.
