Don't know about what it's being reported by BBS versus the ROM but 1% every 4 minutes equates to 15% battery usage an hour with screen on. Definitely no issues there.

Hello everybody!

This is my first contribution for the O4X community. Hope you like it! :)

I have managed to change the Wi-Fi MAC address of my device and now I share this technique with you.

What is a MAC address?

A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. It may also be known as a burned-in address, an Ethernet hardware address (EHA), hardware address or physical address. (Source: Wikipedia)

Why would somebody change his/her MAC address?

- To access the internet where it is restricted to particular addresses.

- To hide his/her illegal activity. (Though this is not effective enough since the Android system sends product information and a lot of other things to the Google servers and I'm sure that previous IP addresses could be searched for if somebody does something really nasty.)

Is it legal to change the MAC address?

As far as I know, it is. However, I firmly discourage you on doing anything illegal with changed/unchanged MAC.

Let's do it!

What do you need?

- A rooted device.

- A file manager that can explore the root filesystem.

How does this exactly work?

Normally, the Wi-Fi driver gets the MAC address from the built-in chip then it writes the address to '/data/misc/wifi/config_mac'. This is done at a very early stage at bootup, I didn't check when, probably in native binaries or somewhere at the framework (though I doubt the latter). This is the original burned-in address. This cannot be changed with software modifications, but only by soldering off the chip from the motherboard and rewriting its contents. Our Wi-Fi device is a Broadcom BCM4330. It has very good built-in features and the open source driver can be found in our kernel sources. So what you have to do is editing the '/data/misc/wifi/config_mac' file with a modified address.

Before you change your MAC address in any way, turn off Wi-Fi! I recommend writing down your original address somewhere (just to be extra secured).

- If you delete the file or use an invalid one (e.g. 000000000000, ffffffffffff or 133713371337), Wi-Fi will stuck at turning on and you need to do a reboot to get it working again.

- Since the file is created everytime again at boot, it is not persistent. If you reboot, it is gone. If you would like to use it permanently, create a script (like 'echo "001122334455" > /data/misc/wifi/config_mac') with some script manager application and set it to run at each reboot.

I did not test this on CM. Since CM has the Wi-Fi module built into the kernel (Anybody knows why??), it may not work. Somebody pls try and report.

Every custom modification to devices have risks. Use this at your own risk!

Have fun and enjoy! :)
[LG Optimus 4X HD] arx-7-arbalest:
Hi, thanks for the support :)

I would like to say that I have managed to change the mac adress on the Cyanogenmod (cm10.1) by editing a file called "bcmdhd.cal", which is located in system/etc/wifi; the line is for example

I only change the "38" with "39".

I have to edit it before installing the rom (every time I install the rom, I must say :D ), because my sister has another 4X, and with the same mac adress the router goes crazy :)
[LG Optimus 4X HD] Adam77Root:
Thanks for pointing it out. :good:

Does the bcmdhd.cal editing change the MAC persistently? I assume it does.

Sent from my LG-P880
[LG Optimus 4X HD] arx-7-arbalest:
yes, i change it in the zip, then after the install the wifi menu reports the new adress.

EDIT.... i found that my trick worked on the first nightlies of the cm10.1; your way does work on the stable cyanogen and last nightly :)

sorry for my english... :(

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] :
Hi guys,

First post on these forums. I hope I'm not double posting but I could find quite what I was looking for.

My brother dropped his SK17i, the screen is cracked but still completely working, and the earpiece doesn't appear to be working ie. during a call you cannot hear the person talking but they can. The headphone jack works for a call though, and no other speakers are damaged. I downloaded ToggleHeadset2 but it wont open so I assume it won't work, but I tried SoundAbout and it also doesn't improve the situation any. Pretty sure its just a broken earpiece speaker which needs replaced.

Its running Android 4.0.2. (Latest Sony firmware update). I'd like to get into mobile phone fixing and he said if I can sort it out its mine. I'm pretty confident about having a hoke about inside it cause i've messed with laptops and desktops before but I'd like a bit of advice if possible.

I've found lots of good guides to open the phone, replacing the screen will be no problem, but I want to sort the speaker before investing in the screen which is dearer.

My questions are:

1. Is this the component I need to buy? <url removed> darn...can't post links yet! Ok well could someone link me to the component I would need?

2. What specific tools will I need for this? Soldering required etc?

I'm sorry if these are easily answerable elsewhere, I tried...
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Aneel:
see bro its always risky to work with the device opened up and you might go wrong also sometimes.. a good advice is take the phone for Service to Sony if you are still in warranty. if you are not in warranty and cannot afford to spend money i would say there would be some 3rd party repairing centers in your city where they charge a little less... whatever it is no one here on XDA developers would be blamed if you mess up with your phone

Al the Best bro

Best Regards

Aneel
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] :
Thanks for the reply. :) Of course I would never blame anyone if I followed their advice and I ended up destroying the phone, just wanted to know what level of task it is before I attempt it, like would this require soldering it would it be a ribbon slide in and out job. I own anti-static mats, wrist grounding things, and quite a few small laptop tools. Just trying to get an idea of what is actually involved in this before I have the phone in pieces. :good:

Like I said I'm excited to try open the phone myself and learn something maybe, any advice would be welcome. :highfive:

I've finally upgraded from my good ol' Xperia Play to HTC Sensation XE, and to my surprise, it was already rooted which is great. I've had setcpu on my Xperia and have always used the conservative governor and deadline (cfq was unavailable).

On my HTC, there's an option of cfq and interactive governor. What would be the best setup for performance but also taking battery into consideration? I don't need a perfect balance of both, perhaps leaning a bit more for performance and less for battery.

Thanks!

[LG Nitro HD] Sywars:
What is the Best Rom For Performance?

Taking into account a combination of kernels and drivers, which rom has higher processing performance?
[LG Nitro HD] Swetnes:
IMO

Well it depends on a lot of factors and what is important to you:

Best overall performance - cm10.1 with stock kernel. But games will feel sluggish but system performance is fantastic.

Best gaming performance - stock ICS any based on v20f.

Best battery performance - cm10.1 + wind kernel or any of the v20 stock ICS + wind kernel.

Best stability performance: Gingerbread - there are phones out there that for what ever reason start have reboot issues with stock ICS or cm10.x but if yours isn't one of the few with these issues stock ICS any v20.

Overclocking will always impact these but stability may suffer along with battery life and longevity of the phone.
[LG Nitro HD] Sywars:
For Gaming Use With The Wind Stock Rom Kernel + ICS ICS Adreno Drivers + Overclock Using em 1.62 Who Will I be a good performance?
[LG Nitro HD] Technocian:
The highest benchmarks on Antutu I have ever gotten was with HO!NO!'s Full Throttle CM9. For the longest time this was the ONLY stable custom ROM for the Nitro and to this day, it still in the top 3 for many categories (stability, performance, benchmarks, battery life).

I've tried the stock V20f ROMs, latest CM10.1, PAC-ROM, and ran them all with stock and Wind kernel. The highest Antutu score I got outside of HO!NO!'s CM9 was about 6,000. On HO!NO!'s CM9 I regularly approach 9,000 after slimming the ROM down.
[LG Nitro HD] Swetnes:
I agree with you when it came to that benchmark. However that doesn't translate into real world performance. When it comes to battery life the combination of wind/cm10.1 blows the doors off of full throttle.

I think the use of benchmarks as a measure of performance either on a computer or a phone will ALWAYS lead people into making bad decisions. For example the ROM that does the worst in gaming benchmarks stock ICS v20f gives you the best gaming performance. Go figure.

Hello everyone. Apologies if I'm posting in the incorrect section feel free to move this if necessary. I recently attempted to root my Verizon Galaxy Note 2 VRAMC3 with Adam Outler's NoYouVerizon program and after about 5 attempts I keep getting the same error over and over. I tried to post a reply with my pastebin log on his thread but as I'm a newly registered user with under 10 posts it would not let me reply there and directed me here. I didn't want to just spam 10 posts to be able to post there so I hope this was the right thing to do.

I have installed and uninstall/reinstalled drivers attempting to fix this problem and have been unsuccessful. Followed all the steps in the guide to a T. Have rooted several phones before in the past with no problems at all this is the first time I've had to ask for help. My pastebin log link is below.

[Galaxy Tab Q&A, Help & Troubleshooting] DevonKing:
I have 6 SCH-i800 Verizon Galaxy Tabs that I purchased new from a company dumping it's stock of old tablets. I decided that I could use them for business and hand them out to my technicians to use for field work. However I did not want them to be able to access certain settings which I could not disable without having root access.

I started with just one tablet that I had already activated on Verizon and flashed it using the latest Cubed3 ROM by dsb9938. It seemed to be the best custom rom for my needs and worked great on the tab. 3G stayed active and connected under everything I threw at it for well over 48 hours. GPS worked. Everything was perfect.

I proceeded to flash the other tablets without issue, and then one by one began to activate them on Verizon. It wasn't until after this that I discovered to my horror that every tablet I activated

after

the flash had 3G connection issues. Randomly throughout the day the data will go into Upload only and then just go into data disconnect mode. The only way to get it out is to turn the data connection off then back on.

The only tablet not doing this is the one I activated prior to the flashing. Other than that all the tablets are identical, even down to the loaded software.

I tried wiping and re-flashing the tablets, but the same problem persists.

Same for all tabs.

Hardware Version: I800.0.4

Model: SCH-I800

Firmware: 2.3.5

Baseband: S:I800.0.4V.EI04

Kernel: 2.6.35.7-dsb9938.VZW.GTab.EI04.1.1.2

Build:SCH-I800.EI04

I flashed every tab using Heimdall 1.1.1, and from the latest update from Verizon, MC2.

Thanks in advance for the assistance.

I apologize in advance if this all seems basic, but I've googled and googled and I'm not getting anything but confused. My girlfriend has a Photon Q that she OTA upgraded to Jelly Bean, and she absolutely hates it. She desperately wants to go back to ICS. Is that possible, and if so how can I do it?
[Motorola Photon Q 4G LTE] arrrghhh:
Use the FXZ thread.

There's the getvar lines to remove, and there's some additional lines which need to be removed if you're downgrading.

Edit - this post may help you with the additional lines that need to be removed in order to downgrade.
[Motorola Photon Q 4G LTE] dereckbarker:
Okay, so I think I get it for the most part. I download RSD Lite and the proper FXZ file for what I'm downgrading to, which would be 4.0.4 in my case since I'm going ICS. I edit the XML file to remove the line <step operation="getvar" var="max-download-size" /> and should be good to go. Assuming I'm correct with my understanding, I'm still confused about one three. There appear to be three different FXZ for 4.0.4, I'm not sure which of the three I should use.
[Motorola Photon Q 4G LTE] arrrghhh:
Well since you're downgrading there are some additional lines which you have to remove from the XML file. Read my edit, I linked you to another post which talks about that.

As for which one to download, that is up to you. Motorola released 3 OTA's for ICS, and one for JB. I have no clue which one was being used previously on your device, but it's likely ASA-14 as it was the last ICS firmware.
[Motorola Photon Q 4G LTE] dereckbarker:
Well it appear I may be SOL anyways as I can't seem to get into recovery mode. Upon starting up and pressing power + Vol up I get nothing but a screen of an android with an ! coming out of its chest for about a minute or two and then the phone reboots. Damn thing isn't rooted or anything, it's a stock phone.
[Motorola Photon Q 4G LTE] arrrghhh:
That's stock recovery. You need to put the phone in fastboot mode, not recovery mode.

adb reboot bootloader

should bring you to fastboot mode. Or, use cam+power to get the menu when the phone turns on.
