[Q] I installed CM10 on my T-mobile Blaze and lost 4G capability! Please help! - Samsung Galaxy S Blaze 4G

I rooted my T-mobile galaxy blaze 4g and installed ICS 2.3.6. A short time later I upgraded to CM10.0.0. It was there that I noticed that I lost my 4G capability. I only have 2G/3G service now. Where did it go and how can I get it back? Please help!

Go into settings/wireless/more/mobile networks/network mode and check mark the one with lte. This should solve your problem

Did that but still showing 2G/3G and an H+ for my network connectivity. Could it be because T Mobile does not recognize this particular ROM yet and therefore has not authorized it to carry 4g? Kind of at a loss as what to do anybody with other suggestions please.

H+ is 4g

OK cool. I hate to belabor this topic but it why is the 4g intermittent and 3g and 2g seem to be default? It only goes into H+ intermittently it's in very few circumstances. Primarily remains in 3g and menu allows me to go down to 2g. I'm pretty new, I've done a lot of reading, I'm just trying to understand. Thank you for all your help.

Its just as frequent as your last ics , the difference is 4g from T-Mobile never leaves the screen but you were still alternating 3g/4g just the same. Another thing is T-Mobile has less 4g towers than say sprint or atnt sooo really nothings changed. Enjoy !!!

TMO ROMs show 4G full time to avoid panic.
TMO calls HSPA14 and up "4G".
H+ is HSPA+21 and higher.
Phone automatically ramps down to H or "3G" when data connection is more or less idle. Under use, it'll ramp up to H+. Potential battery saving...
Nothing has changed compared with before, except the dummy icon.

Stuck on hsdpa (not H+) Noob help.

Ok I've rooted my phone via one click method. I have the rcmix hd 3.4 rotate Rom with leeroids 2.2.4 kernel. So far I love it except ever since I changed from factory default Rom I have no H+ or what I'm under the impression of it being 4G. Instead I'm stuck just a regular H with data arrows underneath. Any ideas for a noob?

Don't quote me here, but I'm pretty sure the afr001 and afr002 ROMs don't have an H+ icon since they are the European Desire HD ROMs. So you may be getting 4G HSPA+, but it doesn't have an icon for it.

I'd bet that is what is happening.
That ROM may only show an H. I know with the one AR ROM i was using it would actually switch between "E", "3G" and "H+" depending on what i was using.
Thanx I think this is very possibly as it seems I have moderately fast connection when off WiFi. Is there possibly an app or a reference to see if the signal strength or speed of connection equates to that of 4G?

Just run a speed test with the app and you'll know right away what's going on.
Where do you live?
The stock AT&T setup shows an H+ icon even when in hsdpa... to let customers think they are getting 4g. Your rom is probably correct in showing you an H for hsdpa, because AT&T only has 4g service in like 6 cities nation wide. So unless you live in one of those cities you're not getting 4g anyway.

Wrong! The phone is using the H+ frequency, now if the backhauling has been done yet is the question.

There is no "H+" Frequency, 2G, 3G, HSPA+, they all use either 850 or 1900. He's right, they have enabled the "+" to show up all the time, even if you aren't getting an HSPA+ connection. It's very deceiving and AT&T is in some hot water right now over their false advertising, google it to see.

No 3g?

Hey guys I was noticing my G2x only ever says 4g or 2g, never 3g. Why is that? It would definitely be nice to switch from 3g to 4g instead of to 2g.
Am I missing something about how t-mobile's 4g is an expanded 3g?

it is as he stated above... tmobile just "dropped" the 3G icon (or LG did it)
so if your area is only 3G at the moment like mine is it will display 4G but that is not accurate.... im calling tmobile about this and will ask more... plus i wanna know when my area will be getting 4G (prolly never)
I just came from Verizon. U have to laugh when I see 4g on my phone. Much slower than my Verizon's 3g. Phone is awesome though. Worth the move.

Has anyone tried going to Setting > Wireless and Networks > Mobile Networks and changing the network mode to try and get a 3G symbol to show up? I'd try it myself but I get no signal in the house I'm in at the moment (Wi-Fi calling FTW!).
I forced my network to used WCDMA and my icon says 4g. But I checked in About Phone Status and it says I'm on hspa not hspa+. So it appears 4g means maybe 3 or 4g.

For the life of me I can't get this phone to connect to hspa. My vibrant right next to me can but all I get is umts on the g2x. Hate having a phone that is "4g" but slower than my "3g" phone. I've reset it and tried everything I can think of.

Toggle to cdma prl in York LTE settings and reboot. If I have LTE set on I get 1x all the time. Not sure if its the real problem or fix but seems to work for me. I'm also in a 3g area.

Same issue here.
This morning I wake up, and my thunderbolt is stock on 1x. If I switch to 4G, it will do 4g, but back to CDMA only, and stuck on 1x. I have 4G at home, but leave it on 3G because I normally am at work with no 4G coverage.
I flashed the stock mr 2 rom just to confirm and used the official radio just to be safe. No change.
Googled around a bit and here is a fix that worked for me...
Dialer -> ##778# ->Call -> Edit -> 000000 -> modem settings ->Rev A
Switch to enable from eHRPD and then hit back once. Menu->Commit.
Solved for me, but I don't know if it has adverse effects...

This makes your phone use the "old" version of EvDO. Basically what all 3g phones that don't have 4g radios use. If your area doesn't have 4g, doing this change shouldn't effect you at all and might get you 3g if you are stuck in 1x.

1X here all morning too. I'm in San Francisco.
On the plus side, my DL/UL speeds suck, but ping is 9 ms, so Mobile Hotspotting is still relatively fast.

Dont think you can use data while on a call when using EVDO, like you could on LTE.

You can in 3G with the Thunderbolt. I did it yesterday. I work in 4G but live in 3G, but this feature is what finally made me pick the TB over the Charge.
I started this morning with the 3G/4G toggle on 3G only, to save battery, and around lunch I switched 4G back on and it has been there since... I haven't had issues with 1X. Must be a regional thing.

Does anyone else lose 4g a lot?

I've tried WCDMA Preferred and GSM Auto (PRL) but I am constantly losing 4G switching back and forth in areas I have never had a problem.
Download the app called 'Network' in the Android market and set it to WCDMA only.
That isn't a solution but why wouldn't I just set it in the testing mode? Why download another app?
I lose 4g often too....and I go down to 2g....what happened to 3g? My old prepaid Cricket phone had a consistent 3g signal all over Tucson, while the 4g is really fast, it isn't reliable, and almost (almost) makes me wanna go back on cricket.
this radio is garbage.
my g2 was piss poor with 4g and this one is even worse.
I can watch it sit on the table and go from full bars of 4g to 2 bars of 2g/edge and STAY there.
sorry for the uninformed question, but is this something that can be fixed in a new rom, or mod?
I added data tweaks to my roms. I don't have any issues.

It's not the radio. It's more likely the 4G signal in your area. I am in Atlanta and I have full bar 4G almost everywhere I go. At home it will drop down to 2G but I have wifi there.
As for 3G, this is a 4G radio. We're you joking about the 3G expectations?

Point #1 - You are incorrect. I am saturated with T-Mos "fake" 4G coverage and have never had a phone drop it like this one does.
Point #2 - What are you asking the other posted about 3G expectations. This phone doesn't have a 4G radio. T-Mo doesn't have 4G. They have 3G that they market as 4G.

Everyone has "fake" 4G coverage. LTE isn't technically classified as "4G" either, the specification calls for rates of at least 100/mbps. T-Mobile currently has faster and more widespread pre-4G coverage than any other carrier, and the phone does have a pre-4G radio. The phone does support HSDPA at rates up to 21Mbps, and does is in fact have a pre-4G radio. And as far as my other comment not being a solution, have you tried it before bashing it? I've had plenty of luck with that solution personally and I figured it would be kind of me to share, but I suppose I stand corrected.

Yes. Thanks to your roms, I have signal in places I never had before (like the bathroom at work. I can now surf while doing my "business" and important "paper work" in my "office", ya know.?
while i poop.
What are data tweaks?
I have noticed like the iPhone 4 that if you touch that metal peice on the back around the camera the signal drops. I got a case that covers that up and that fixed all my 4g signal problems. My phone stays on 4g most of the time where I am. The T-Mobile network where I live works very well though.

If you are on the tmobile network, you can't get 3g anymore if your phone is a 4g phone. It's either 4g or 2g.

have all HSDPA towers been upgraded to HSDPA+?
Or does the phone just recognize all HSDPA as '4G'?

It recognizes all HSDPA as '4G', I have full signal in certain areas with a '4G' icon but get speeds around 1Mbps and when I check the actual signal with third-party apps it is registered as HSDPA.

[Q] Blaze does not get 4G after mod

I have not been able to connect with 4g since I modded Blaze.
I have used many ROMs and settings, searched for weeks to find answer to activate 4g, no joy.
4g works perfectly with stock Rom. My wife has identical phone that easily and automatically picks up 4g sitting next to me while my modded phone only gets 3G or occasionally H+. We have swapped SIMs to confirm SIM and hardware are functional as well as signal reception.
I have uploaded and reloaded many different mods: stable, nightly, paranoid, Pac man, etc.- Same result, everything works pretty well except never 4G
All installs were clean and fresh.
I have seen this question in this forum and other, but no replies/ solution.
Anyone have an answer why the 4G does not work on my modded Blaze?
H+ is 4g it's just displayed differently. Nothing is wrong with your phone.

I suspected, but could not confirm that H+ and 4g were the same, Thank you
P.S. Speeds on H+ with 4 bars are ping 1048ms, 9.19 Mbps Down and 1.87 Mbps down. Isn't 4G faster?
Our phones do not have true 4g. The stock ROM shows 4g more as a marketing gimmick. I'm my experience with the blaze 3g has better ping times while 4g or whatever you want to call it has better speeds. Of course it all depends on location

EDIT: Oh I'm sorry, I just realized that H+ is like 3.5G or something. I have the exhibit "4g" and it was H or 3.5G
Either that or H was 2.5G
