[Q] Can 3G data be turned off and just use 1x?

First off, Sorry for the novel I'm about to write! :o

Secondly, Thank you to all of you here who Dev, Mod, and help people with questions.

I always have data turned on. I just spent the last 3 weeks in Alaska where I was constantly roaming and only had a 1x connection. For the first time in the 2 1/2 months I've had my phone (on SleeperROM 1.0.09 since 2011-11-21), my battery was lasting for more than 48 hours on a charge even with medium use (for me at least):

1 or 2 10-15 minute calls and 5 or 6 texts per day

background data on

auto-sync off

check 6 mail accounts and facebook once every few hours

several 5-10 minute sessions on IMDB

about an hour and a half of playing games before bed

I just updated yesterday to Sleeper ROM 1.0.10 with the Scrolling Status Menu mod and love it. As soon as I have enough posts to thank SenseiSimple and toadlife I'll do so.

I was going to request that there be a Wireless Tether or off/Wi-Fi/Tether and "Data Speed" off/3G/4G buttons added. Before posting though I did go to the original 14 Statusbar Toggle Buttons thread by lidroid to make sure they hadn't already been added since it was brought over to the Epic 4G.

Someone over there had already requested Hotspot and 2G/3G toggle, which got me thinking...

3G = better battery life than 4G

1x = better battery life than 3G :D

We already have a Statusbar mod that shows when 1x is being used instead of 3G as backwards compatibility with older Sprint towers and other carriers, so is it possible to turn on the 1x data connection without activating the 3G?

Would not be surprised if it isn't possible due to tower controlled connection selecting, 1x/3G selection hard coded into firmware or drivers, or as someone suggested back in lidroid's thread, that it's an API that Android doesn't allow access to.

Anyone know if it can be done or has been tried?

I wasn't able to find anything by searching for '1x' '3g' 'data toggle'

Would force roaming work for you? Could try roam control in the the market .
[Epic 4G Q&A, Help & Troubleshooting] Talon65442:
Thanks for the suggestion Adam. Roam Control would definitely be one way of doing it. I also looked at a few advanced settings/control apps like JuiceDefender and Tasker. looks like those are ROM dependant on whether they'd be capable or not.

It's not really a major concern for me. It would be nice to be able to voluntarily drop down to 1x to increase battery life for the 60% of the day that the phone mostly just sits in my pocket while still being able to get internet calls and chat. Not so much that I'd want to risk getting a family plan that includes my grandparents who travel a lot kicked from a contract that just started. ;)

Primarily curious if anyone else had thought of it or tried it already.

Addendum: Next best thing would be if we had a way to change PRLs on-the-fly (which we don't), then have stock PRL and a hackjob with only Sprint towers on it and use RC to force roaming on hackjob PRL to force 1x and switch PRL to stock to enable 3G/4G data without roaming.

Anyway. Seems like the answer is that it can't be done with what we currently have available for modifying our phones.

Again, sorry for the long posts. I tend to think of ways to do stuff better when I can get my ideas somewhere besides just in my head.

I've flashed the official EI22 modem for my Epic and I am using RandomRom Thunderhawk 2.3.5 Rom but it seems I can't get my 4G to work anymore. I've even reflashed the mostly stock ROM and tried using a different Moden file for EI22 but I still can't seem to get it to work. Has anyone have any thoughts on this?

Any help would be greatful.

I have rebooted the phone and 3x wiped the phone before installing anything and still no luck.
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
If it is anything like my incident, 4G tries to turn but can't get an IP from Sprint. I had to Odin back to EC05, confirm it worked, then root and flash and confirm it works. Then when I did an advanced restore of data it broke again. I had corrupted data. I restored the next older nand and it worked again. Restored some stuff with Titanium that was more recent. Hope this helps.
[Epic 4G Q&A, Help & Troubleshooting] mikezot:
Thanks. I'll try that over the weekend. I'l just wipe everything and start from scratch and redownload any apps. There's nothing I really need to worry about.

I just have to Odin EC03, then root and then it should be, in theory, working and then I can change the Rom.

---------- Post added at 04:50 PM ---------- Previous post was at 04:44 PM ----------

Or, just go back to EC05, then upgrade to gingerbread and then root and reinstall the Rom I want?
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
Yes, Odining to EC05, one click root then you should be able to flash any ROM you want. Occasionally a GB ROM will be picky about coming from EC05. Then you would have to do the OTA, Odin in recovery from CWM 5.0.2.7 with reboot unchecked, pull battery, put battery in and boot right to CWM and flash the ROM.

You have apps loading and filling caches throughout the day. Get Memory Booster Lite and open the task killer to see all the crap loading into your memory. Freeze or uninstall the apps you don't use regularly and use the task killer once in awhile...especially after using a browser.

Ha, never noticed...but the system apps with com.xxxx long press those and add them to the white list so you don't always see them. There are free apps like Bloatfreezer that will do that and another program called Autostarts that will keep them from loading at start up.

CM7 converts you to an MTD partition table and yaffs2 file system. The warnings tell you that to go back to regular BML ROMs you need to Odin back to stock EC05 with the PIT file and repartition back to the stock partition table and file system. Here is how to do that:

Every once in a while my display will flicker and when it does it is typically very hot. Does the display tend to have overheating issues? I had first noticed it rooted on a Voodoo Color kernel and later I went back to stock. Yesterday it happened again on the stock kernel/ROM.
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
Was that voodoo color kernel also the one that overclocked the GPU? Sounds like the display is damaged from some type of OC or UV. This happened to a friend's phone a little while after using a kernel that undervolted the display.

help w/shutdown animation

hey guys. ive been lurking fow a while finally and registered. first off thanks to all the wonderful devs and non devs who make this device truly epic! i have a questions re: shutdownani

im currently on MTD CleanGB (newest build) - my theme is honeycomb explosion, i have the green helix green robot BOOT working but not shutdown. what ive tried to do an "researched" was to use a rooted file explorer, make sure read/write is checked navigated to /system/media/(then made a /video/shutdown/"the png files")

my assumption was that since the current ROM doest have the path of /video/shutdown that i would have to create the path with the shutdownani .zip of my choice (in this case its green helix boot shutdown). but its not working. any help would be appreciated:)

Does anyone know if the camera hardware is different between the Fascinate? I am talking about the actual optical sensor on the back of the phone, I know that the Fascinate does not have a front facing camera. The reason I ask is that my brothers Fascinate shoots much better video than my Epic. Both phones are bone stock and have default settings in the camera.apk. I noticed that the camera.apk for the fascinate seems much more advanced than our camera.apk. would it be posible to use the fascinate camera.apk on the epic? I know that I would no longer have an option to use the front facing camera in the camera.apk but I never used it anyway and video quality is much more important to me. Anyone have any tips for good video quality such as third party apks, settings, etc?

[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
Assuming you are rooted and have installed clockworkmod in Rom Manager, which will install CWM 5.0.2.7, then you can indeed install CleanGB BML on your phone to access the Hotspot. There are also Sleeper and a ROM from Hoffman1984 which is EL30, latest firmware.

My daughter lives 1500 miles away and she keeps getting pestered to "update" the OTA update from Sprint/Samsung. She keeps saying no, but is there a way to turn this off? On my HTC I can turn it off from the System Updates menu but she says that menu's not there in hers.

Also, if she goes ahead and takes the OTA update, how hard will it be to re-root it walking her through it over the phone? Is there a new zip file she could flash that includes the updates so she doesn't lose root?

Thanks.
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
Some developers put their ROMs up for ROM Manager to list. It is the same as downloading it from the ROM thread...just sometimes more convenient. In ROM Manager you can then choose install ROM as a quicker way instead of 3 finger and install from CWM.

Woo..lots of questions...OK if she is rooted and has changed anything like deleted bloat, on a custom ROM, kernel, added GPS fix, keyboard fix, any of that stuff then the install will fail anyway. In order to root the OTA it will require the use of a PC and Odin...not for the squeamish. Would she be able to flash a custom ROM?

Thanks. She's already running a custom ROM, the ERA_EI22_RC_2.2 with the stock kernel, and she could handle Odin I think. Should I just tell her to accept the OTA and deal with it afterwards if there's any problems?

If she is running a custom rom it won't do the ota... you can just flash an el30 custom rom to get you there or odin to ec05 and accept all the ota's... but then you'd have to reroot... easy way is to find an el30 rom she would want to run and flash it...

No longer necessary. Older versions of Clockwork did not wipe completely but CWM 5.0.2.7 wipe clean in 1 shot. Things improve over time.

1 more quesion about CWM if you dont mind :D

why we need to mount / unmount the partition ?

for example we need to mount /system before flashing bootanimation.zip

i know that the bootanimation is in the /system partition, but why not mount all the partition when CWM loaded, so we dont need to select mount /system first. (i'm often forget to mount /system when flashing)
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
CWM relies on the flashing script to mount the partitions. Scripts written for BML do not make system writeable on MTD. If the script was written for MTD it does mount system....it's a transistion. It is the Developers choice to not automatically mount everything. Probably because bad things can happen to novices.
[Epic 4G Q&A, Help & Troubleshooting] webslasher:
so that's why we need to mount / remount, because of partition map and noobproof system :D, it is good, but pretty annoying if i flash something, but didnt see any change since i usually forget to mount and the script isn't giving any error. lol , thanks kenny
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
Yeah, someone forgot to add an error check that the system is mounted first. Maybe next version. If the scripts you flash are made for MTD you will not have to mount/unmount. As a side note I have never had to unmount yet. It always showed already unmounted.

If you are back on EC05 stock you can either check for updates and accept the OTA or do a one-click root, update to CWM 5.0.2.7 and flash an EI22 ROM from Development or an EL30 ROM (recommended to avoid update nag). Then you can flash the modem update deltas if you want the EI22 or EL30 modems.

Question on CM9 4.0.3 Build (Possible issues)

First off, Amazing build, especially for it being Alpha 2 only. So my questions/issues are currently:

When I reboot phone (Starting at approximatly 55% battery) upon finishing, it's around 16% or less. Is this normal (Note, i believe i fixed it due to leaving the ever lasting boot animation on, however just making sure)

Second, Sometimes, my bars are Blue (meaning mobile data and such are working great) but soon turn grey in same location as before ( I don't have it set to turn off data after a certain time) Problem is now to regain data i have to switch to Airplane mode and back again. Not sure if it's an on going issue or not. I haven't added any other kernels or anything. Just the usual stuff needed to flash this version on the phone. thanks for any help that can be provided. Once again, Great job to all involved with the development of this, it's greatly appreciated.
[Epic 4G Q&A, Help & Troubleshooting] KennyG123:
The first thing is a normal bug that has been around since rooting Epics. Don't reboot with less than 70% unless plugged into a charger. If you get that just shut down, pull battery for 2 minutes then put in and reboot, percentage should be back up.

2nd thing did you try your internet connection? I am pretty sure the google sync connection goes off and on.
