works pretty well, I get a stronger signal then before and get 4G where I didn't before

I guess everyone in LA is capped around 15 down/5 up from what I've seen, which is understandable considering the huge amount of 4G traffic there must be here... the speeds shown are just about max for me right now
[Verizon Droid Charge] dsbaciga:
I used odin3 v1.3 to install the tar package, if that's what you mean.
[Verizon Droid Charge] cujo6801:
I open it with winwar and its showing to modem files cp modem.bin and lte modem.bin
[Verizon Droid Charge] anoninja118:
yeah its the LTE modem and CDMA modem
[Verizon Droid Charge] cujo6801:
coolieo ...thanks
[Verizon Droid Charge] hiien:
So for this package we don't have to flash to another modem before going to EP1Q? As in I can go from EE4 -> EP1Q via ODIN?
[Verizon Droid Charge] anoninja118:
you mean complete rom package? I've seen that you need to go to GB first: EE4 -> EP1F or EP1H -> EP1Q
[Verizon Droid Charge] neyenlives:
anyone have the latest Odin download? 1.8.5 i think? i dont need to download a 650Mb package from the sticky to get a 5Mb application...
[Verizon Droid Charge] neyenlives:
modems have never had to be flashed in order to my knowledge, only roms
[Verizon Droid Charge] anoninja118:
yeah thats why i asked if he meant the whole rom or the modem... if modem, flash whatever you want on whatever rom, if rom, you gotta go in a certain order to get to EP1Q
[Verizon Droid Charge] neyenlives:
you have a download link to the latest Odin? We seem to have a download for everything but that by itself

*edit nevermind found one

[Verizon Droid Charge] anoninja118:
I should probably download it too lol.. I've been using 1.3 with no problems since my Fascinate
[Verizon Droid Charge] carbonwhiskey:
So how do we flash this file?

I see 2 .bin files. Someone else mentioned they flasehd a tar file?

do we just use the PDA button on ODIN and flash like we would tar files/ROMS?
[Verizon Droid Charge] maqsur:
That's what I did (ODIN, select PDA-tar file).

Running now. Hardware listed as EP1
[Verizon Droid Charge] hiien:
Sorry I might've been confusing at first, I was referring to the modem but that's good to know, thanks!
[Verizon Droid Charge] carbonwhiskey:
So you flashed the bin files individually?

When I unpack the file I downloaded, I don't see any tar files, but only 2 bin files.
[Verizon Droid Charge] bkhorn:
Try: http://www.google.com/url?sa=t&sour...rnQis_1Jg&sig2=8or4FsUTsvIbyCfii7D44Q&cad=rja
[Verizon Droid Charge] anoninja118:
no you put the entire EP1Q modems .tar file in the PDA section in odin and you're good
[Verizon Droid Charge] billku:
Sorry for the noobish question, anoninja118, but I'm on Froyo Humble 1.51 as well -- can you just Odin flash this TAR and put the new radios on your phone, simple as that? Or do you need to wipe data/cache, disable voodoo lagfix, etc. Would love to try this, but don't really feel like redoing everything else on my phone... thanks in advance!!!
[Verizon Droid Charge] neyenlives:
Vast improvement, running Humble Froyo 1.5.1

4G is now picking up inside the office building where it never would before and my 3G signal is also much improved.
[Verizon Droid Charge] neyenlives:
Simple, simply flash the tar file using Odin, nothing else, no booting into recovery, no wiping anything, power off, power into download mode, flash it using PDA button in Odin and wait for it to reboot. Done.
[Verizon Droid Charge] dsbaciga:
I didn't do anything but install the modems. I didn't wipe the cache or anything like that.
[Verizon Droid Charge] anoninja118:
yeah as jamesnmandy said just flash the modems .tar in odin and you're good
[Verizon Droid Charge] billku:
Thanks, guys!
[Verizon Droid Charge] neyenlives:
just flashed it to a co-workers Charge that sits in the cube right next to me, his is much improved also, he is running stock EE4 (now with EP1Q radio of course)

Just a little info, we work in an engineering office on the second floor, building has half glass, windows everywhere, we are also in the deepest red 4G prime signal strength area according to VZW's coverage maps. Outside we can get 20+Mbps 4G speeds, walk inside and 4G disappears and we get a middle of the road 3G signal but we both have been seeing the 4g>3g>1xrtt>3g>4g switching issue on both handsets, his running EE4 bone stock and mine running Humble Froyo 1.5.1 with the stock EE4 radio.

But this EP1Q radio not only boosted 4G and 3G signal but it also seems to have stopped the signal hunting issue. The 4G towers just got turned on in our area a few weeks ago so I attributed the issues to the local system since it was manifesting itself the same on two different devices running different firmware, although identical radios. This tells me however that Samsung has had to tweak the radio firmware since release. I would imagine after the Fascinate fiasco VZW probably told them to **** or get off the pot before people started getting their Charges replaced with Thunderbolts or LG Revos.
[Verizon Droid Charge] jimmydafish:
That is 100% incorrect. They are not independent. The radios and the RIL files are linked together. Mixing and matching may work, but there is no guarantee either. The only way to determine if one is working better than the next is to flash and find out.
[Verizon Droid Charge] chaddymoff:
Wow, just flashed and booted up. My desk in my office is typically a "Struggling for 1x Zone." I've never had consistent 4G nor, with prior phones, consistent 3G.

Sitting at 4G - 3 Bars right now. Haven't tested performance, but sure seems improved.
[Verizon Droid Charge] madsquabbles:
just flashed. used to get poor signal and 3g here at work. now decent signal and 4g! had the same experience when i flashed the leaked GB rom/radio combos, now i'm glad to have it in froyo.
[Verizon Droid Charge] hyunjpark:
Thanks. I just flashed the modems over. I didn't have an issue with 4g, my apt is covered. But flashed it because I wanted better reception in other places. Can't tell if it has improved yet but made a few phone calls and sent some texts and have no issues. BTW I'm running humble 1.42 froyo rom and it seems to be working well.
[Verizon Droid Charge] iratesubscriber:
My 4g coverage is always 4 or 5 bars and it continues on the epq1 modem. In brooklyn my downloads range from 26Mbps to 32Mbps off peak. I cant see how this new radio will improve that but i'll report back.
[Verizon Droid Charge] rand4ll:
I have never had an issue with any rom/modem combination and never read about them either...i have give as far as using eclair modems on GB roms and vice versa...even used eclair modems in cm7...so from experience I have never seen nor had issues.

However, thanks for the information!

EDIT: After reading through this it seems that the RIL in android is radio agnostic so it shouldn't matter what radio is used with the RIL assuming they are both built correctly...

www.netmite.com/android/mydroid/development/pdk/docs/telephony.html
[Verizon Droid Charge] fortesquieu:
They are independent. Sorry to call you out but it's the truth. I have been using different types of radios and ROMs combinations since my Incredible days, even on Charge.

You could use GB radios on Froyo roms and vice versa.
[Verizon Droid Charge] asdecker:
My CDMA modem works but when I toggle the 4G I get signal bars but no 3G or 4G. Odin again?

Edit: Odin'd again using 1.3. Took a couple minutes but 3G icon showed up with LTE modem, just on outskirts to get 4G
[Verizon Droid Charge] hogowner:
where are people getting the tar modem files for ODIN? There are only 2 bin files....where are the tar modem files for EP1Q?

Thanks
[Verizon Droid Charge] hyunjpark:
The link is on the OP. Download that which is a .tar package and just flash with odin. Don't uncompress the file.
[Verizon Droid Charge] lucky13:
The two bin files are inside the tar file, just download the tar file, open odin, and select that tar file.
[Verizon Droid Charge] hogowner:
it is a tar file? when I download it, it is a zip file isn't it?
[Verizon Droid Charge] lucky13:
I averaged 6 speedtests and came up with this:

Before radio flash:

After radio flash:

Note the worse ping on the second run, but oh well, these are close to the average of the 6 tests. No 4G out here in the boonies of Nebraska yet, so I couldn't test that.

Also, my radio didn't flash the first time, I had to do it again with the latest version of ODIN, it seemed I had an older version which didn't work.
[Verizon Droid Charge] lucky13:
It might appear to be a .zip file from the icon, but I'd bet of you check the actual file extension, it's .tar.
[Verizon Droid Charge] hogowner:
actually when I download the file...and install with odin.....it starts to go...says LTE modem in the upper left hand box...seems to download in...then it fails.....
[Verizon Droid Charge] lucky13:
I had that happen also. I am used to pulling the battery when I ODIN from back in the OG Droid days, but when I put the battery back in, ODIN flashed it fine. If you had the battery out, put it back in after ODIN finds the phone.
[Verizon Droid Charge] hogowner:
I tried a 3 times in a row....finally took...I did not put the battery back in..and it worked

[Verizon Droid Charge] neyenlives:
Speeds for me have been comparable and quite honestly, nobody should be expecting to compare modems that way unless something really major as changed. Cellular data will always be variable. This modem fixes weak 4G and stops it from doing the switching thing, that's worth having even if it meant getting 14Mbps instead of 15Mbps.
[Verizon Droid Charge] PeterDLai:
Is the RIL (Radio Layer Interface) part of the ROM, kernel, or modem? I'm using stock EE4 with imnuts kernel and EP1Q modem, and I'm wondering if upgrading my baseband to "EP1" made any changes to the RIL or not.
[Verizon Droid Charge] Tornlogic:
Still bounces back and forth for me. I see no improvement, however, I'm glad others do.
[Verizon Droid Charge] maqsur:
I'm using gummy charged 1.91 (froyo) with this new ep1q radio. I did some speedtests on 4g (i'm in new york metro area). Great speeds, rivals my cable connection.

did anyone notice the call quality is not that great with this radio? I have been noticing when someone is calling me, the voice volume goes up and down....
[Verizon Droid Charge] GoBlue13:
I've noticed this as well. Was hoping I was just imagining it. Guess not.

My battery life has also fallen dramatically.
[Verizon Droid Charge] black02ss:
I just installed this on my humble FE Rom. Lot strongere signal. True test will be tomorrow at work.
[Verizon Droid Charge] black02ss:
OK I can say that this improved greatly. I tested at my home with is 4G enhanced services and and averagin a good bit increase over the stock radios and my connection hasn't dropped. Tomorrow at work is the true test. Report back in 6 hrs.

hrm...i did a good 20 minutes of talking on mine yesterday evening and none of those issues...weird
[Verizon Droid Charge] Outsider2011:
so i odin'd and i just need to know how to find out if im on EP1Q this is what my info says:

kernel version: 2.6.35.7-ep1h-cl323089

build number: SCH-I510.EP1F

my spee test are only hittinh 8 dwnload and averaging 3 upload and i live in phx AZ.... so am i on EP1Q or not?
[Verizon Droid Charge] fortesquieu:
If you look at your baseband, it became EP1, which is also EP1Q radio, I have no idea why they took out "Q".
[Verizon Droid Charge] Delicate Donut:
Is there an ee4 file package to go back to in case I get poor voice quality? I remember on my captivate I tried like 5 different modems before I found one that had good data speeds and voice quality.

Are you using the Speedtest.net app or are you going to speakeasy.net/speedtest in the browser? The app is inaccurate on Gingerbread, the website however is accurate.
[Verizon Droid Charge] hyunjpark:
Any one having dropped data connection issues? I flashed the modem yesterday and it seemed fine but yesterday and today the phone will show the 3G or LTE icon but I will have no data connection. When I toggle the mobile data, it shows no data at all and won't come back on unless I reboot my phone. My connection was fine on EE4 but with this modem my speeds have dropped actually. Probably going back to EE4 modem.
[Verizon Droid Charge] hazard209:
Instead of rebooting, try going into airplane mode for 30 seconds or so and then then turn it off. See if that helps at all.
[Verizon Droid Charge] PeterDLai:
I get that issue with any modem and I've extensively tested each one. Not sure if it's an issue with the phone, SIM card, or just the network. One of these days I'll try getting my SIM card swapped but I'm doubtful it will help. Sometimes I can go hours without dropping data connectivity, other times it'll drop a few times per hour.
[Verizon Droid Charge] Outsider2011:
Thank you..i tried it and my dwnloads are 15 but uploads are kinda terrible only getting .50...but i live in phoenix and they only have so little states/citys for testing

Premium Droid Charge
[Verizon Droid Charge] PeterGunz:
My experience has been 3G in places that I usually have 4G. Before this radio my signal had only dropped to 3G a couple times since I've owned the phone. Just today I have seen it 5-10 times.
[Verizon Droid Charge] neyenlives:
That's pretty amazing because I have had the exact opposite experience. A full 24hours into this and I haven't had any of the switching or drop issues. I was in the middle of nowhere on a golf course all day today nowhere near an interstate and it was fine.
[Verizon Droid Charge] greene.phillip:
Just flashed these with Odin 1.83 no issues at all. However... I seem to be getting consistently lower 4g speeds with them. Did 6 tests prior to flash average around 6mb, 6 after average 3.5-4. Will test further tomorrow but nothing good to say yet o.O
[Verizon Droid Charge] Tornlogic:
I don't care so much about synthetic benchmark speeds, but what really bothers me is the reduced battery life. Its horrible.
[Verizon Droid Charge] asdecker:
Im getting not so good battery life too. On gummy 1.9.1 with Imo's 13.3 kernel and EP1Q.
[Verizon Droid Charge] maqsur:
Had same setup, but got pretty good battery life imho. For example, left uncharged overnight, only dropped a few percentage points in 8-9 hours. After one hour of phone call, dropped maybe 5-6 percent. Watch netflix for 1-2 hours and drop about 20 percent per hour (with full brightness, and via data connection).

So I could definitely make it an entire day before pluggin it back in. I live in nyc metro area, with 4g coverage. Maybe that makes an effect. Also, I don't run really anything in background.

Problem is there are so many things that will affect the battery life. If i stayed at my work with data connection on, then i would lose battery quickly because the verizon signal sucks there. (0-1 bars) But at home area, i get 4 bars all the time, so that helps.
[Verizon Droid Charge] asdecker:
Im in a strong 3g area with a little bit 4g so I don't change to LTE often at all. I think I've flashed and.changed stuff so much recently I just need to chill out a couple days and let the phone iron it out.

has anyone had their phones randomly shut down after installing the EP1Q modem? it's happened to me about 3 times today so far, and it's only started occurring once I had installed the modem.
[Verizon Droid Charge] neyenlives:
No problems here, I don't know how fast it is, I don't obsess over speedtests, it does everything I want lightning fast. I'd give up a little speed for this kind of stability any day. Even at 15Mbps its faster than most peoples home broad-band so whats the problem?

Nope, not once, neen running it all weekend. You running an undervolted or overclocked kernel?

I'm seeing no noticeable difference using these modems. I'm on Gummy Froyo 1.9.1 with the latest PBJ kernel.

My work is on a fringe area - also have a local airport competing with airwave usage, so coverage is typically shaky to begin with. A work colleague has the Thunderdolt and he's in-and-out of 3g/4g all day, but I've never seen 4g here.

lte modem is AMAZING. I feel like I'm getting better life on these radios but i could be wrong, i'm not really sure. the speeds on these are amazing though. Im running gummy gbe ep1q and ran a speedtest (yea i know about the problems with gb and speedtest) and got 36 Mbps consistantly. then I ran a speakeasy test and got two mistakes (i think) of 80Mbps and 143 Mbps lol.

the EE4 radio is much better if you are worried about understanding phone calls.
[Verizon Droid Charge] hiien:
Honestly I believe this modem success to be a YMMV thing. The only way to know if it's good for you or not is to flash it and see for yourself. Worst case scenario, you can always flash back to EE4 if EP1Q is no good for you.
[Verizon Droid Charge] bgorrell:
Thought I'd report my experience.

I ran this modem for the past week. I'm not in a 4g area, but was hoping to see improved 3g signals at least. Unfortunately, I observed slight to no improvement.

I'd have left it on anyways, but noted a significant loss of battery life from about 20 hours to 10-12 hours.

Switched back to EE4 modem today and battery life is back to normal. So for me at least, this modem was a bust.

Running Humble 1.51, pbj, no OC. Also I work in a very weak 3g area, FWIW.
[Verizon Droid Charge] trparky:
Maybe they need to do some more tweaking to these modem firmwares. Any signs of a new leak, newer than EP1Q?

What kernels are you guys running on?

Battery life on EP1Q has been normal for me, and I'm running imoseyon's kernel.
[Verizon Droid Charge] trparky:
I've not done anything yet to my phone, I've not even rooted it yet. I came here into this thread to look for any semblance of stability for the 3G/4G radios but knowing that other people aren't having good luck with it, I'll be staying away from that firmware.

I was hoping that the EP1Q modem firmwares would be the godsend that we've all been looking for when it comes to data stability on the Droid Charge but it doesn't seem like it. Close, but not close enough to break out the champagne.

Now if something comes along, say a newer firmware and it does turn out to be the godsend that we've been waiting for, you best believe I'm going to be flashing that onto my phone. But until then, stock for me.
[Verizon Droid Charge] greene.phillip:
I've been using the new modems a little while and... I also upgrade to a new kernel version of pbj and a newer gummycharged rom at the same time. I can't say for sure the cause but it seems like my 4g is lower performance than before. However my battery life seems to be improved.

I want to go back to compare speeds/battery and I tried to flash the above but it just hangs on 'Downloading to VIA...' with a nearly full bar. Any suggestions?

Update: Reflashed the EP1Q modems and it went fine. Still working fine. Going to try the EE4 modems again. Only slight difference I noticed is the EE4 modem flashes cp_modem.bin before ltemodem as the EP1Q does.

Tried a few more times and it finally completed successfully.
[Verizon Droid Charge] trparky:
Based upon what a user over on the Verizon Wireless Community Forums said, EP1Q is an older build than what is currently available to official Samsung firmware beta testers. Apparently EP1Q was dropped by Samsung for whatever reason.

Some build with "4H" in it is the latest official beta build but I've not been able to track down anything with that in it as far as firmwares for this phone. Apparently it has turned out to be a pretty damn stable build as per the user that told me the above.
