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.

Isn't Android Revolution HD is in the Generic HTC One M8 section?
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.
That code doesn't do anything on the Viper rom

Sounds like you guys need to flash CleanROM...
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.

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.
Rayden1000
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.

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
my phone will drop connection and then not reconnect. no voice, no data. (wifi still works)
what I've tried:
1. Different radios/firmware
2. different roms
3. different preferred network types
4. switching airplane mode on and off
what I haven't tried:
1. different sim
2. calling tmobile for suggestions
What else could cause this problem?
it could be a hardware issue
Hello,
I have the same issue than you !
I am facing issues such as call drop and no 3G data connection in some area in my region since I have 5 signal bar and H letter displayed (HSDPA connection)...
I have found a workaround consisting in:
1 - Switching to GSM Only mode (2G Only)
2 - Desabling Mobile Data Connection
Then it works, I can pass and receive voice call ...
Regards,
Nino
I'm new to the Sensation and having the exact same issue.
Followed the stickies in the Dev section to S-OFF, root and bypass SIM lock and then once the SIM card is inserted I get only GSM and no data.
If you use *#*#4636#*#* in the Dialer and go to Phone Information do you notice that it always switches to WCDMA preferred? I change to GSM/CDMA auto PRL like all my other Android devices (on Rogers Wireless) and it disconnects, reconnects but only for GSM and no data. It sometimes says it's connected to EDGE or HSPA but no icon at the top right and then it reverts back to GSM.
I have also tried flashing virtually every firmware, ensuring that the radio and RILs match (I had an HTC Desire Z so the HTC phones are not new to me entirely). I don't know what else to do. I tried a Bell SIM card and tried all of the same options to no avail.
I really hope someone can figure this out. I don't want to have destroyed a phone that I just bought for my wife. Her Atrix broke and I purchased that outright as well, so this is really killing my wallet. I've been through about 10 Android devices and I wouldn't say I'm a newb, but I really do feel like one right now. This sucks!

I did try every setting in there. The new sim card fixed it! So I guess our problems are different.
Here is whats happening! I go into an awful area with no cell service and when i return into an area with good service... It shows all my bars, 3G icon, but its all grayed out and will not return with color... Also i have no data connectivity at all. The only way to resolve this problem is a reboot. I have the Nexus s 4G KL1 radio... This has happened twice in 2 days. Can anybody tell me what this could be? I tried the KL2 radio and the same thing happened. So I went back to KL1. I am running Cyanogenmod 7.1 stable. Any help would be appreciated, I like this phone and dont want to have to go back to my slow Evo.
Happens on ICS ROMs. I switched back to GB because of that issue.
OHHH ok that makes sense since i was on an ics rom... That sux i love the ics roms to. Is this an issue they know about and are working on?
Yes I am sure the devs know about this issue. A lot of people already reported this issue on the ROM's threads. I think there was a fix in the CM9 repositories that was merged this week.
well thats good news since were i live its not good service and im in and out of service a lot. Thanks for chiming in and letting me know! I was wondering if i had a bad radio or some thing lol...
This happens to my I9020T as well (with stock ICS, Pixel ROM, and Brainmaster's Stock and MIUI ICS ROMs). So, it's definitely an ICS issue. My network connection won't reconnect after I ride the subway (underground, where there's no signal) for about an hour. The only way to fix it is by doing a reboot (enabling and disabling Airplane mode doesn't fix it).
I just tried switching radios: from KI1 to KF1. I'll update on the result later tonight.
Sounds like exactly what happened to me.
I went back to gingerbread. I haven't had the issue since!
Just out of curiosity have you tried the KL2 radio with CM9/Latest nightly and then toggle your Data Enabled or the data roaming? If that works it might save you the reboot. Settings, wireless & Networks/more, Mobile networks, Data enabled.
You could try toggling the data roaming too.

I've tried enabling-disabling Data as well, and it doesn't fix it.
The weird thing is the same issue happened to my girlfriend's T-Mobile G2 with Gingerbread last week, when I unchecked the "Use only 2G network" setting on her phone and forgot to check it back. So, when she told me the issue when she got home, I re-enabled the "Use only 2G network" setting again, and her phone haven't had the reconnect issue ever since.
So, my speculation right now is this reconnect to network failure issue has something to do with the Nexus S' 3G/4G network type setting.
I definitely think you're right
I am having somewhat the same problem.
My phone keeps switching from UMTS:3 to HSDPA and back to UMTS:3
This is draining the hell out of my battery. But when I have it on EDGE 2G I'm getting good battery life.
the issue is not that big for me. I just give it a few moments with it in sleep and when I go to use it again it fixes its self.

Update!!!! I have since switch off of the I c s rom. I have not had the incident happen even 1 time since doing so. I am totally convinced it's on ice cream sandwich roms.

I doubt the radio would make a difference. I think the issue lies in the Phone application.
I could be misinformed here, but if i recall correctly, our phones radio is relatively stupid as far as radios go, and the intelligent parts are actually done as a part of the phone application. This only applies to CDMA Variants of the Nexus S, but it could be the reason that the ICS update was pulled (As thats where CM and others get the ICS version of the phone app.).
After taking the subway for about an hour last night, my NS actually reconnected when I got back up to ground level. One thing that I didn't do is listen to music (PowerAmp); I was always listening to music when I had those network reconnect issues.
Anyway, I hope this issue gets fixed in the upcoming official Google ICS update, that should be released in a few weeks*.
*http://www.engadget.com/2012/03/15/confirmed-ics-coming-to-the-nexus-s-in-the-next-few-weeks/
I've found that if you just stick it in airplane mode when you are about to go into known no service area and then take it out of ap mode when you know you have a signal you can save from having to reboot to reconnect.
My building at work is a tomb for sprints signal and it works for me every day w/o rebooting ...
To all of you having network reconnect issues -- do you use any battery saving apps, like JuideDefender or GreenPower? I use one, and I'm thinking that its network toggling internal API method has something to do with this issue.
Yesterday, I disabled my GreenPower app right before I took the subway, in which my NS couldn't receive any network signal for about an hour. Then, when I went back up to ground level my NS was able to reconnect to my network successfully.
I'll do the same test later after work and update back tonight.
I hope this is the right place to ask. If not please let me know so I can post correctly.
I have been trying to find a Sense ROM for the HTC Inspire 4G that will actually allow for switching between "3G/2G" and "2G only" (forcing the EDGE network) due to poor 3G signal at work. I went down the list of Sense ROMs for the phone and installed them to test. Thus far no love. I am aware of the "*#*#4636#*#*" in the dialer and choosing the appropriate network but "GSM only" will not work. It just keeps using the 3G network regardless of the selection. I have spent a month trying to figure out how to do this whether it be via ROM or other methods such as adb push. At this point I have found nothing that will work long term. I have found one time fixes on a couple of ROMS which only work upon one boot. After rebooting the phone, the process has to be repeated (involves installing a radio). Other fixes make "2G only" permanent which I do not want.
I am pretty sure this is not hardware lock because CM versions allow for the switching and locking in bands with no issues. I am convinced it has to be a lockout by the HTC software. I would prefer a Sense ROM due to faster camera and other things, but with the extremely poor 3G signal at work, my battery life is being mutilated by the constant switching between 3G and 2G bands making Sense a no-go.
I am not looking for a toggle switch. I just want the ability to switch between the two at will on a Sense based ROM. If any one has a fix or a ROM that works consistently and long term please let me know. It is greatly appreciated.
Try doing Android Revolution HD worked for me both 3G and 4G plus 2G

You can do the dialer thing or the way settings>networks>and mobile network>mobile network settings>gsm only hoped this helped

There are quite a few toggle apps out in the play store that can help with toggle...
Not looking for toggle

I am not looking for the toggle apps. I am wanting a Sense ROM for the HTC Inspire that will actually allow me to force GSM only mode (2G only). Thus far no luck, even with ARHD. I have only been able to force 2G only in non sense roms such as CM7. I want to know if there is a Sense ROM that allows for it on the Inspire and if so, perhaps there are additional settings I missed. I know how to utilize the *#*#4636#*#* menu to select the "GSM only" option but regardless it always goes right back to showing the H+ and AT&T's fake 4G mode. GSM only seems to be disabled completely.

I am not sure. I have narrowed it down to one of two things - either it is software or firmware. The 2G only works fine on AOSP style ROMs such as CM, Gingerbeast, and aospX. Sense ROMs are a no go though, including ones for the Desire HD which is what leads me to believe it may be firmware.
I was running the sabsa prime rom which is a sense based rom ans was unable to find a toggle like you are looking for. I am now using the jellytime rom by randomblade and it has the ability to force edge network or 2g in the settings.

I've got verizon m8 with "Unlocked 4G LTE" off ebay, and I'm trying to make it work on t-mobile US.
The problem I'm facing: everything seems to work (LTE included) until it loses the tower (because e.g. I'm moving between towers). It then gets stuck with one bar signal in the status but no actual connection, and it's not even trying to reconnect.
Resetting network by toggling airplane mode on/off brings signal back.
Phone is soff/rooted/supercid with latest firmware (6.21.605.3).
What I tried so far:
- changed sku_id in default.xml to TMOUS (and LRA_US, as set by s-rom)
- tried to flash att and wwe radios - no signal after this, reverted to stock
- enabled all cdma and lte bands in qpst
- tried latest s-rom and viper
- tried different options for "preferred network type": gsm/wcdma/lte, cdma/evdo/gsm/wcdma/lte etc
Nothing helps
any hope or time to get rid of it?
thanks

spent a week on this and gave up. Best solution is to sell and get a used t-mobile version :-/ Just did this and t-mob edition gets a much better reception in addition to not losing towers.
I saw multiple people claiming to be successfully using gsm/lte on vzw m8 and I'm really curious if it's something I missed or there is some kind of different hardware involved.
