[Sprint HTC EVO 4G LTE] rawintellect:
Are you hboot 2.09 and s-on?

When you open supersu does it ask to update the binary and then reboot?

Does Adfree reboot the phone when you try to update the host file? Read on my friends!

Hey folks smarter than me,

I have a question, it's not really a problem but maybe you all can help me here. I used to use an app called 3g/4g optimizer prior to updating to JB. It essentially edits the build.prop file to increase the 3g/4g speeds. Specifically these entries:

ro.ril.gprsclass=

ro.ril.hsdpa.category=

ro.ril.hsupa.category=

ro.ril.hsxpa=1

The Rom I'm using now (flex360s Stock w/ Goodies 3.25) has these settings at:

ro.ril.gprsclass=10

ro.ril.hsdpa.category=8

ro.ril.hsupa.category=6

ro.ril.hsxpa=1

Well I didn't like them (I'm all about speed. I know flex loves the battery life so I can respect the 10 setting) and I thought that since I upgraded to hboot 2.09 (yeah yeah I know...never take an OTA...but hey man I am s-on and I plan to stay that way so I wanted the latest radios and a geek's gotta do what a geek's gotta do :)) that editing the build.prop file was not going to happen for me because when I do that now and reboot whatever setting is in the Stock with Goodies.zip overlays my changes. But what I did was go into his zip and change the build.prop THERE and reflashed and it worked!! my changes now stick to whatever I flashed in the ROM. Which are:

ro.ril.gprsclass=12

ro.ril.hsdpa.category=15

ro.ril.hsupa.category=7

ro.ril.hsxpa=1

So I'm asking: (yeah it's a long buildup to a question lol)

Do you think it is it some setting in the ROM preventing me from just changing my build.prop and having it stick between boots?

Mind you I'm rooted and using root explorer to make these changes and my permissions are right rw-r--r-- and it used to work on ICS.

Or is it the new hboot 2.09 saying "no way man you are gonna use whatever build.prop is in the rom and that's it mister!!! no changes!!!" ??? Orrrr is it JB itself saying no way???? :confused:

As I said it's not a big deal. I can get around it by just reflashing my modified version of flex's rom. So I'm happy. Just curious.

In short, can anyone who has hboot 2.09 and is s-on AND IS ROOTED edit their build.prop with root explorer or es file manager AND have it stick between boots?

Oh and PS...with my settings I can pull 2327 down on 3g (see screenie below :cool:) which is pretty good for 3g in my area. Hence my impetus for changing these settings.

As an afterthought.I guess I could flash an ICS kernel and rom and test this myself and see if I can change it with the new hboot.

******UPDATE 1/1/13******

Happy NEW YEAR!!! and what's a great way to start off the year? A resolution to the superuser/Adfree/reboot problem! (read on)

If you're hboot 2.09 (and if you took the latest OTA you are) and s-on (if you're s-off this doesn't apply to you as you're aren't having this issue) then this thread is for you.

If you've read above and a few posts down this thread you will notice several issues with hboot 2.09

for a full description of the problem please go here and read:

Ok...that's the bad news. The good news? There's a fix!!!!!!!!!!!

Over in the android development section a developer by the name of flar2 has created the first over clockable kernel for the Evo 4g LTE. What he's ALSO done is create a system write module so the over clocking settings stick between boots. What this also does is allow writes to the /system partition WITHOUT REBOOTING THE PHONE. And your changes to the partitions stick!!!

The catch? When you flash a new ROM most of them install a kernel. So you will need to redo the process listed below.

Here's what we folks with hboot 2.09 with s-on need to do:

Go to flar2's kernel thread and download his zip: Go here -----> http://xdaforums.com/showthread.php?t=2075542

(1) boot your phone into fastboot usb in the bootloader

(2) extract the boot.img file from the Elemental-EVO-JB-v0.7.zip (it's located in the /boot directory)

(3) place it into your adb/sdk folder (if you don't know what adb/sdk is please read step #2 in my Manual root thread here: http://xdaforums.com/showthread.php?t=2038123

(4) open an adb command window

(5) issue the 'fastboot flash boot boot.img' command that will push the modified stock kernel to your boot partition

(6) boot to recovery and flash the Elemental-EVO-JB-v0.7.zip as normal selecting your AROMA installer overclocking options (if you want stock speed you can select it) Use the volume up/down keys to move around in the AROMA installer as the touch screen is rather buggy. use the power button to select an option.

(7) reboot your phone and that's it! say goodbye to /system partition reboots!

As proof this works please notice my phone now runs at 1.8Ghz and these settings stick between boots. Also I can temp unroot and I can update Adfree hostfiles with no reboots:

ATTENTION!!! None of this is my work. Please go to flar2's thread and thank him! I'm just pointing the way!!!!!

Please donate to him!!!! I did and it was the best $20 I ever spent!!!
