Nandroid Backup! Its your friend!

READ ENTIRE POST

Mention what rom and mods u used with results in a post please! :)

**If you flashed mashup and miss your data speed you need to redo mod 1**

One user that was plauged with switch to 1x being reported it being eliminated by the mods

Confirmed working on MIUI, eclipse 1.2 & 2.0.3, stock 2.3.4 and CM7

Mod 1 "may" work on any other 3G phones, mod 2 when posted "may" work on other 3G MOTO phones.

Mod 1

The Problem:

Since I do not have internet at home and I live in a poor service area any increase in 3G data speeds I can get is beneficial. So, I started looking into a way to increase my 3G data speeds.

Please let me know what rom you are using when you post something

Note: The first boot I did on some of these took a few minutes for 3G to first come up. Any reboots later it showed up immediately. I had no service issue and triangle once or twice while I was checking all of these. Reboot always fixed it.

The Solution:

First, nandroid backup prior to changing anything on your phone is a good policy to follow.

Most of the build.prop edits I’ve found are for GSM phones. I did find one thing that might help. I have confirmation from another source this hack works for them as well.

The line to be edited in build.prop which is in your /system/ folder by root explorer, root browser or any other editor/method of choice (make sure you backup your build.prop first):

persist.ril.uart.flowctrl=1

Change the “1” to “10”, save your build.prop, and reboot.

You can change the 1 to 1-10 and null or blank.

These are my results below in kb/s.

1=baseline 75-100 kb/s

0= no service – Don’t do this!

2-5 = 100 kb/s with some temp increases

6-9 = 150-200 kb/s

10 = 250-350 kb/s

A null value gives me 150-300 kb/s with large fluctuations.

I found that “10” gave me the best speed with most consistent results.

These speeds were clocked in actual large file downloads not a speed testing app.

I found that speed testing apps do not give accurate results. The real downloading gives real results.

Note: With this a tester was getting 500kb/s downloading a rom over 3G.

Please reply back with any results you find as I am looking for conformation of my findings.

If you try this in a different ROM please let me know your findings as well. This SHOULD work in any rooted X2.

Doesn't work on liberty for the moment. Gonna attempt it on fully stock liberty soon

Thanks to MoonShadow-NM for his assistance with the write up

Mod 2 - Can be used along with Mod1

Atrix lib replacement mod

This mod I found helped with increasing data speeds in my poor service location as well as an increase in speed in a good service location

Signal at a horrible -102 dBm I was getting a consistant 200kb/s download where I only had 100kb/s before using this in conjunction with mod 1 at a value of 10

Signal at a nice -62 dBm I got a nice 400-500kbs consistant download speed where I only had 250-300kb/s before using this in conjunction with mod 1 at a value of 10

Note: You may see a better increase as I am a huge data user and subject to network optimization by evil red.

This mod at my house also stopped my phone from jumping between two towers. One with a -130 signal and the better with a -102.

The attached file is an Atrix lib_motoril.so file. It is a different file from our stock blur file. It is about 50kb smaller in size then any X2 blurbased non-port rom file I found. It was given to me to try by a Alien port user after talking with him about his nice data speeds and connections prior to any modifications.

This is a fairly easy file swapping mod.

Download the attached atrix lib and extract wherever you want.

Navigate to the /system/lib/ folder in a file manager of choice and either backup by placing a .bak after the .so of the original libmoto_ril.so file.

Go to where you extracted the Atrix lib file. Copy and paste that file to your /system/lib folder and then set permissions to the rw-r--r-- for it..

Reboot and let me know if you had the same good results as me.

Thanks to kinevil for the atrix lib and idea to try this file!

I make sure BSR is installed before I try anything so I can do a battery pull and get into BSR. Wipe cache and dalvik if any issues come up first then you can always nandroid after that if needed.

-----------------------------------------------------------------------------------------------------------------

Mod 3 - May help with connection stability. Not speed.

Easy build.prop addtion

In a fike manager such as root browser and root manager got to /system/ and open your build.prop to edit.

Add the following line.

ro.mot.eri.losalert.delay=

The standard mod for this us 1000. Feel free to play around with it. Please post your results.

Happy modding!
