I would like to open discussion on developing a permanent fix for the horrible bug with Android 2.1 CDMA devices defaulting to a Preferred Network of GSM. My goal will be to develop a script or app that will either run at boot, via a cronjob, or as an icon/widget on the homescreen that will set the Preferred Network to CDMA.
The "Testing" app (*#*#4636#*#*) looks to be /system/bin/iqd. I have used strace to capture what the process is doing when the Preferred Network is properly set to CDMA, but I could not decipher it (didn't see any I/O on any files, only RAM). I've attached my log in case someone else can make sense of it.
This is the #1 issue on my Evo, and the only thing I have done to notice any change in battery life, and the difference is absolutely huge. Without applying this fix after EVERY reboot, I only get 4 hours max out of my phone. After applying the fix, I get 8-12 hours, which is actually reasonable. This desperately needs a permanent fix, and I can't imagine I am alone here.
Cheers!
This seems like a great idea.
I just checked my phone, it's set to CDMA auto. I am running fully stock, but rooted and unlocked.

I just checked as well and this does not seem to be an issue with me. Mine is already set to CDMA(Auto). I have fresh installed and I also checked on my brothers stock Evo.
Actually I think everyone is affected by this problem.
Go to *#*#4636#*#* , phone info, and you will see that it says CDMA.
So far so good. Now, hit menu and then choose select radio band. and you will see a force close,don't panic now you will be back at the menu, hit phone information again and you will see that now it says GSM! choose cdma and hit back, done.
Now, I'm not sure if that actually does anything for battery life, as the phone doesn't even have a GSM radio. I think its just a pointless HTC bug from the hero days since android did not have native cdma, so HTC had to hack it in.
The purpose of this thread is not to determine whether or not you are affected by the bug. There are tons of other threads discussing that. If your "Time without Signal" value is excessively high (usually around 50%), you are affected, and are only getting about half of the potential battery life from your device (for Evos, it makes the device nearly non-functional because it won't last through a day. A friend also confirmed this on his Incredible, and now gets 2 days out of his battery instead of 1).
Let's limit this thread to only those who are affected by the issue and those looking for a solution. Thanks!
Now, has anyone taken a look at my strace log? Or does anyone have any idea where/how the phone's radio values are set? I noticed some references to "ciq-backend," perhaps this is a deamon, service, or command that we could tap into. Any ideas?

It absolutely has a huge affect on my battery as well as two of my friends' Evos (two are 0002, one is 0003), although I can't speak for all Evo owners. We all experience the same 4-5 hours battery life without the fix, and 8-12 hours with the fix applied. It's just such a pain in the butt to do it EVERY time the phone reboots.
well, its not the fix you are looking for, BUT, i have found that it makes changing this after a reboot MUCH easier.
Download an app called simply "network" from the market.
It gets you right into the test menu, and then you can hit select radio band and complete the process from there.
I think this should be something that could be built into roms but not sure... Also.. i am still not sure that by do doing hte select radio and getting the FC, that THIS isnt what is causing use to see it come up as GSM. No proof of that other than just the thought, but it could be like a default that after the FC causes to revert to (but i did notice better batter life after it than before and its something i have dont on every rom every time i reboot since it was discoverd.
Hope the network app helps a little until there is a permanent solution!
Thanks for noticing this.
I am having the same issue and i have HORRIBLE battery life. Im getting close to my 30 days and might want to switch this evo in for a newer one, but I dont want to lose root.
If i can get some more battery life out of this... I might just be a little happier.
I get like 12-15 without the fix and moderate usage and wifi/GPS on all the time (no 4g tho), but I tried changing it and we'll find out if it's any better.
4-5 hours has to be an exaggeration unless it's something to do with 4g :\
Its a big bug on htc phones and it will say cdma but its really on gsm.. some roms will get a "time without signal" which does drain a ton off battery cuz the phone is looking for a gsm network constantly and in a sense is roaming on cdma. We just dont see anything to do with roaming cuz its suppose to be our defaulted network.
Also we dont have a full gsm radio but we can connect to gsm networks.

We can connect to GSM networks on this phone? I am confused, where have I been lol?
No these phones cannot be used on gsm.
Yes I do see that now after I hit the menu and selected the band and it does seem to be an issue. My time without signal is around 45% which is insane considering I've had full bars all day. If we can figure some way to auto set this it would be great.

Mine has never been GSM. It has always veeb cdma auto
Sometimes while the battery is low, I like to put the phone into 2G mode also known as edge and get off the 4G network. I remember my myTouch had this with cyanogen and really any other asop Rom also had it.
How do we enable it on a device running sense? Or this phone for this case.
Thanks
Sent from my HTC Sensation 4G using XDA App
It should be under the Mobile Network sub menu.. it's not ASOP or Cyanogen exclusive.
The option doesn't exist for us on our ROM. I like that feature too. Here is a workaround. Go into your dialer and type in *#*#4636#*#* and a menu will pop up. Go to Phone Information and you'll see a drop down that shows WCDMA Preferred as the default. Go into the drop down menu and choose GSM Only. It will cycle the radio off and then back on and then you will have Edge only. Alternatively if you select WCDMA Only, you will only ever have 4G. This is useful if you live in an area that is right on the cusp on 2G/4G. Our phones will drop to Edge if the Edge signal is stronger than the HSPA signal. Sometimes this is annoying since you could still have 4G speed if the phone didn't automatically switch to Edge.
Also, I don't remember who the dev is, but there is an app in the Market called Network. This app allows you to go right into that phone info menu mentioned above without needing to put that code into the dialer. It can be hard to find since there are so many search results if you search for "network" in the Market. If you are interested I will look up the devs name for you and you can find it that way. Hope this helps.
Edit: The person above is correct actually, I didn't see it before but you can choose WCDMA/GSM Auto, GSM Only or WCDMA Only from that Mobile Network submenu in the Wireless & Networks menu in your standard settings menu. Thank you for pointing that out.

Putting 2g only on kills battery faster....harder for stuff to sync faster ...phone stays awake longer. Google put out a whole video on YouTube about it.
Sent from my HTC Sensation 4G using XDA Premium App
wow, totally forgot to try this trick at work. My phone sits there with a full strength 2G signal, but the bars lie, it's very unreliable and cripplingly slow (much slower than edge is capable of). Now I have a 1-2 bar 4G signal and am getting very acceptable speeds. 1.8Mbps down 1.3Mbps up (FCC mobile broadband test, 3 tests averaged).
I just wanted to add that I hunted around for widgets to provide a quick toggle for this function, whether that be forcing GSM as some need to do, or forcing WCDMA as others need to. My search turned up a few like EasySwitch but it seems that none of them work with gingerbread.
No need for the special code...
You can find that here too:
Settings > Wireless & Networks > Mobile Networks > Network Mode

Keeping it on disk space may use more battery charge, but it helps preserve my 2GB 4G data cap. It seems like a reasonable trade-off for me. Does anyone know if the "Data Used" number shown under the "My Account" app is accurate?

it should be under the pulldown notifications bar? or at least I think I remember seeing an option for it on CM9/AOKP. itll have your list of toggles and should have "2G" listed as well. havent tried it out tho cuz Im on Sense now, and if I ever have EDGE data, I usually just connect to WiFi (lol only at my house, service sucks)
I have ALWAYS had very poor AT&T service in my house, from my iphone 3g, iphone 4, iphone 4s....as soon as you pull in my neighborhood AT&T service just goes to ***
I got the One X however and realized I can pick up LTE here when the radio first turns on! I can put it on airplane mode, take it off...and I'll get LTE for about a minute. I get 10mbps down instead of the 1mbps when it's just on "4G"
However..this can barely make it through a SpeedTest as it's 1 or 2 bars of service...then it switches from 2 bar 4G LTE to the 3 or 4 bar "4G"
The phone is thinking I get better service with just the plain 4G so it forces me to connect to that....in reality it's a tonnnn slower and much worse.
Is there any APN setting or any root hacks to force the LTE connection? I get LTE pretty much everywhere in town (las vegas) but like I said my neighborhood doesn't seem to be on AT&T's maps!
If you go to your dialer and type in *#*#4636#*#* it will take to a screen where down a bit from the middle is the option "select network type" tap that and there is and "lte only" option. I have read that this works to force only hspa+ but can't confirm it for forcing lte. Give it a shot though.

I found the screen....Has a bunch of options with "LTE Only" being one of them...however...when I click on that option it flashes as being set to "LTE Only" for half a second and then reverts to the default option of "GSM/WCDMA/LTE auto"
Damn, thought you were on to something!

This does NOT work for forcing either HSPA or LTE. It always reverts back to auto. AT&T does not let you choose your network, period. We will not be able to choose the network unless and until we get the Rogers ROM working on the AT&T units (or until someone builds a custom ROM giving us the functionality of Rogers).

Sure it does... rogers devices and debloated ROMs are the only ones that can be forced into LTE mode. It's AT&T ROMs that can't

If you are rooted and have an unlocked bootloader, try a version of CleanRom or a stock rooted rom which is not an AT&T base. I have been able to lock my radio to LTE (only when not making calls that is) with CR V and I am on AT&T. The only thing is that when you make a call you get bumped to 3g/HSPA because AT&T doesn't do voice over LTE
Do custom ROMs limit the HSPA speed of our phone? Is there some network check where if you're not running on T-Mobile's ROM, you won't be able to access the full speed HSPA+ 42mbps network?
rom won't affect that
have seen a lot of posts with folks getting plus 20mb in the 42mb areas--wish I lived in one--
Do you think the buil.prop settings have anything to do with it?
I remember getting 15mbps a few months back from my home, now the fastest I can get is around 5 :/
sounds like something changed, what do you get in other areas compared to before
some roms don't do as well as others with some folks. but, I never had a rom make that kind of difference.
don't know about buildprop--I doubt it
try the last rom you were on with good speeds. also, maybe the latest radio
I haven't been able to get high speeds like that anywhere really.
What I've noticed is that since switching from the stock ROM, my indicator switches frequently from "H" to "3G". It'll switch back and fourth every 5-10 seconds when I'm using data. This happens with CM9 and CM10 and the modified Sense ROM that I'm running now. I live in an area with excellent 4G coverage and I don't understand why this switching is occurring now when it wasn't back on the stock ROM (and I know the stock ROM had separate indicators for 4G/H and 3G). It doesn't make any sense to me.
the switching is common for a lot of people and is addressed on several threads
if your hboot is under .13 you can flash a newer radio
gotta call it a nite
I don't know if the following setting remains after rooting and installing a custom ROM but check it out and test the different settings:
Settings>Mobile network>Network mode>WCDMA only versus GSM/WCDMA auto
Are you in an HSPA+42 area? T-Mobile only has that in a few markets..

I like my phone switching to edge when HSPA signal is weak because then I still get service and it doesn't kill my battery life. I don't think this would matter because 3G and 4G are on the same bands :/ Which is why I don't understand why it switches....

I am in the Salt Lake City area, which does have HSPA+42
I'll see what I can do with radio flashing. If I get something to work I'll post a guide on it.
I did some tweaks on my phone and saw positive results, I posted a guide for others here.
I was asked to also post this fix that I came up with in the general forum from the CleanROM thead, as it should help people having the same issue. The issue isn't actually related to that ROM but a broader M8 issue that I was unaware of and thought was specific to the ROM. It's been confirmed with multiple users having the issue that the fix below does indeed fix the random data issues that require a reboot/airplane mode toggle to resolve.
A fix for the 4G --> 3G, WiFi --> 4G, WiFi --> 3G, and 1X/3G --> 4G handoff issues that some people may be having is outlined below...
In a nutshell, we just need to change EVDO Rev A to "Enabled" instead of the 3rd "eHRPD" option in EPST.
Dial ##778 --> Edit Mode --> 000000 --> Modem Settings --> Rev A --> Enable --> Upper Right Corner Menu --> Commit Changes
Might cause a reset data connection with the transition due to a possible new IP or hamper simultaneous voice and data over 3G (which is possible), but it will allow the phone to establish a data connection on its own again and not get stuck on eHRPD 's random buggyness. Should transition back to 4G eventually as well
eHRPD basically for allows switching between LTE and EVDO systems seamlessly (no reset data connection from 4G --> 3G and back, slightly faster speeds, same IP, depends on tower...)
Changing this setting basically tells the modem in your phone to act more like a 3G phone when requesting 3G data access. Bypasses the hybrid-ness and just forces you on the legacy EVDO Rev A. network.
If the phone signal (4G is weak) at the time of the eHRPD transition, it can mess up. This change tells it to not bother with that and when the 4G signal isn't available just revert completely to 3G to register and not wait up for transition info. Makes it more cut and dry, and to be honest it does not really impact things. When the phone detects a 4G solid signal again it will switch back on all its own.
Same issue happened on the HTC Thunderbolt when Verizon was messing with things during initial 4G deployment. Only recent changes are the whole VoLTE ramp up, and that could be the cause of this recent crazyness.
To revert this change:
Dial ##778 --> Edit Mode --> 000000 --> Modem Settings --> Rev A --> eHRPD --> Upper Right Corner Menu --> Commit Changes
Thank you for sharing this! Very good find and positive feedback has been showing in response. Worth a try for everyone having these symptoms.

Sadly, this only works with VZW based ROMs. Anything with parts taken from other bases, or a GPE ROM it may not work and the code for EPST might be different/EPST might not work and/or the option may not be there.

After making a Nandroid back up of your current system then do the edit and restore Nandroid if you want :angel:
But to answer the OP, yes. GSM ROMS will not have this option unless the Dev adds it in. Otherwise its a CDMA only function (I believe).

It works on my viperone 1.8, are you on the newer versions that you do not have the new verizon firmware for yet ?
This is great, I come from an HTC One S but also switched between that and a Galaxy Nexus so I could tell a difference in the way my signal acted and we have had signal issues with the HTC One S for quite some time now and it all seemed to stem from when we finally obtained s-off, seemed our One S was never the same, may have been placebo but I was worried it was happening all over again with our blessed M8 lol. The One S was not Verizon and may not be the same issue. I just tried this and it already seems better.Thanks very much. They still have not found a fix for the HTC One S

If you go back to 1.8 then it will probably work for you, 1.8 was the last verizon that worked correctly for your verizon firmware. I was on the 2.3 but had too many wifi issues so I went back to 1.8, which is less wifi issues now with this fix I seem to not have any wifi issues so far so think its working for me. I"am not going to update viperone until the new verizon firmware is out in a zip to flash in recovery, because the wifi issues are not worth it to update now.
Any more successful difference's people have since doing this?
I was listening to a radio show streaming app today on Wi-Fi and the app kept stopping. every 10 minutes or so after trying this fix. It was the first time I listened to this app with this phone but listen to this app all the time with my other phones and never have this issue. It was consistently dropping Wi-Fi and 4g wasn't picking it up. I am running CleanRom with Harmon Kardon. I tried disabling Harmon Kardon to see if that may have been the issue since I am not accustomed to using it yet and it seemed to work better without it but still dropping signal. The signal icons seemed uneffected. I guess I am going to remove Harmon Kardon see if that makes a difference before I revert back from this fix.
I did this and my phone now reverts back to LTE and doesn't get stuck on 3G like it had been doing since day 1. I was getting tired of cycling into and out of airplane mode. Thanks for this advice/fix!
Is this the bug I experience where I have 4G signal, but am "offline"?
If so, that has been driving me nuts. I am on the stock ROM, S-OFF Rooted. Is this present with the off the shelf version?
Reporting back after 3 separate complete wipe/reflash/restores on my M8. Here is my status as of now:
Tuesday: Tried flashing stock recovery and did factory reset. (didn't fix the handoff issue)
Wednesday: Tried flashing RUU then returning back to CleanRom 1.4 (didn't fix the handoff issue)
Thursday: tried the EHRPD fix listed below. So far today NO handoff issues! I don't want to jump the gun, but this appears to have done the trick. I have gone from 1x to 3G to 4G with no issues so far.

If anyone is using the Verizon M8 with a GSM sim and can't access the USSD code ##778# then go into settings -> mobile data -> preferred network -> LTE/CDMA and try running the code again in the dialer. Dont forget to change the preferred network back to Global after applying the fix by the OP.
This has worked great for me. Thanks for posting. Was incredibly frustrating to have to fight with the phone every morning on my way to work to get it to connect to 4g. I had to toggle airplane mode, switch preferred networks and even reboot or some times do all of the above - lol. Thanks again.
Apparently this is a known issue and per Verizon, they're working with HTC to fix it. But I've also read that the problem could be cause by running xposed modules which seemed to be the case with me. I'm s-off running stock and was fine until I installed xposed.

This fix does not impact Wi-Fi directly, just eHRPD for mobile data transitions. Sounds like the app is the problem. Have the same ROM with Harmon Larson installed - no issues.

Yup. Seems to be impacting certain phones regardless of ROM. I'd give it a shot and see if it helps. If not just change it back.
Big thanks to the OP. I've been dealing with the the eHRPD limbo since I got my phone in April. I live in a low 4g area and was experiencing text and mms problems big time. It was always happening when it was bouncing for 3g and 4g. When I would check the network details it would say eHRPD. I would constantly toggle airplane mode off and on and change network preferences to get it to work. Really annoying. Well I tried this last night and the signal is staying in 4g almost all the time and I have experienced no problems with messaging. I am running Viper 1.8 and had to kind of guess to find the edit button after entering the numbers in the dialer, for some reason the Edit button did not show up but it was there when tapped on it. After that it was easy. Thanks again for the help. I wish Verizon was as good.
