Thanx to teh developers

3. I have robo voice

Turn on speaker while in call, and then end the call immediately, this should help untill next reboot. You might try with a new radio.

4. I have a low volume while in call

Replace the original "htcleo.acdb" existing in the following locations with the one attached.

/etc/firmware/

and

system/etc/firmware/

Alternative link and method for solving the low call volume.

5. I dont have enough space on my phone

1. Before flashing your phone, you can edit the flash.cfg file and change the following line:

cache ya 40M >>to>> cache ya 15M

This reduces the cache by 25M with no discernible impact on the speed of the build (imo).

This should give you in excess of 130MB free after a clean flash. Expect that to drop to around 100MB once Market, Flash and a couple of other apps update themselves.

2. Immediate install Z4root to root your device.

Put it on your SD card and then install a file manager from the Market to browse to it and then install and run. Follow the details on the thread... (Note: it may get stuck on 'Rebooting'. Wait a minute or so and then manually reboot - it will work fine and SuperUser will now work after the reboot)

3. Install Move2SD. You can get it from the Market.You can get it from here.

This allows you to move most (not quite all) apps to SD. It is the best option I have found to move most of those awkward apps.

I have now installed pretty much all of my apps that I used to run on non-NAND builds and have moved about 90%+ of them to the SD card. At time of writing I have loads of apps installed and still have over 70MB free

6. I have some battery issues

1. Install Battery Monitor Widget or CurrentWidget from the Market so that you have a way of tracking your current usage.

2. Install Set CPU - free for XDA members from here, but also available on the Market.

After setting your Main Screen to 'OnDemand' and 'Set on Boot', assign SetCPU a couple of profiles. I tend to use:

>> Screen Off: Max/Min 245000, Scaling 'OnDemand', Priority 50%

>> Battery <25% Max 384000/Min 245000, Scaling 'OnDemand', Priority 50%

You can play to your hearts content here, but these give me consistently 7ma in Standby.

Also, you can reduced the sampling rate to 20000 and 'Set on Boot' in Advanced if you like.

3. Avoid power hungry background stuff like animated wallpapers and turn off GPS, Wireless etc. There are LOADS of apps out there that can do this automatically for you free from the market, but I have found that making sure my GPS is off (I have a widget to show me) plus SetCPU is plenty. It may work for you though.

4. Some have reported that Darkstone's suggestion makes a major difference to their power consumption:

"To fix high power drain / usage in standby (60mA or 70mA) disable 'Use wireless networks' in Settings>Location menu. You will now get 7mA or less constantly. I discovered this as the main culprit last night. Also works in other builds."

Thank you goes to Mark5, again.

7. I have no 3G/data, it used to work well with WinMo

You should go

Home Screen>Menu button>Settings>Wireless & Networks>Mobile networks>Access Point Names>Menu Button>New APN

Then you should fill everything needed. If you dont know the right settings for you, you should search for APN settings in this sub-forum. There are thousands of posts with settings in the Cotulla ROM threat alone. Some dedicated TMOUS ROMS come with working APN out of the box

You might look at this blog, too:

THE GPS threat has moved to the next post :)

I read these questions thousands of times, that is why I wrote this FAQ. Some of these tips have helped me, some have helped others. I hope this helps as well
