Problem with 4g - myTouch 4G Q&A, Help & Troubleshooting

I have been flashing different roms for a long time. I never had a problem with my 4g connection. I'm now stuck on 3g. I have tried GB, ICS & JB ROMS. It doesn't matter which one I use u only get 3g. Sometimes I see the H for 4g but only for a few seconds or barely one minute. I have flashed different radios and some of them gave me 4g but only for a short time. I have formatted my sd card and did a full wipe before all the new roms. Nothing is helping me stay in 4g.
I'm not over on my data usage either.

It might just be your phone trying to save battery so its switching to 3g instead of using 4G or it might just be telling you that its 3G. Have you done a speedtest when the 4g flashes on and off

When I have 4g I get 6mbps down and 2 mbps up. On 3g I get 3 down and less than 1 up. How do I the phone to stop trying to save the battery? Even though I didn't have this problem before. I go all over town and it just doesn't stay on 4g.

Try a new ROM, or reflash the radio. but, if you're wanting to go back to 2.3.4 rooted, and want to get Gingerbread even better, check out myGinger ROM in the Dev section. I made it myself

Connection Problems

Recently when I restarted my phone, the 3G symbol doesn't show. Switched to edge and it appeared then switched to 3G again but now can't even connect. Just shows the 4 bars with no edge/3g symbol.

Flashed anything recently? Maybe you're just in a dead zone. What rom and modem are you running?
I haven't rooted my phone yet. My reception is great but it has just acted like this lately.
Sent from my SGH-T959 using XDA App
In that case I'd say its either local interference or perhaps a malfunction with the nearest cell tower. Either way if you haven't rooted yet and it persists, I'd call T-Mobile.
I can now go to edge but still can't to 3g. Thanks. I'll call them.

Also, make sure you're in a 3G area.

Must be the area as aloneinshadow suggested, unless you have changed settings, such as: use only ........ network, intended for battery save. Sorry I can't be more specific but my current rom does not have that option. I just know that 2.1 has it, if you are on Eclair.

Help no 4g

I can't connect to 4g even thought I live in orlando. I only can connect to 3g. I'm using the newest royalmiui. I didn't have any 4g problems untill I flashed royalthunder then I only got 3g all the times. The speedtests I do show 3g speeds. Any help is much appreciated

Try a full wipe including formatting system and boot and reflash your Rom. Also make sure that your Rom supports 4G

I can't format boot in the new recovery. I have done a full wipe for every rom I flashed. All 4g roms. I'm gonna do it again when I get home to see what happens
Sent from my HTC Glacier using XDA App
Maybe the 4G tower is down? I'm not sure if roms have to be specially made to support HSPA+ because a) HSPA+ is the same technology as 3G so it should be backwards compatible; and b) the HSPA+ chip in the mytouch is only 14.4 mbps which is the fastest HSPA(3G) chip, not 21 which is HSPA+. I think.

check your coverage map on tmobile.com I have had the same issue and I almost started flaming rom cookers... even on cm7 I get 3g speeds. turns out the part of town I live in has low 4g coverages. Usually stock roms only have the H or H+ icon on the framework. so even when you're on 3g it shows H, even when you're on 4g it shows H. on custom roms notice you have 3 different icons. (or 4) H, 3g, EDGE, (GPRS)
H stands for 4g. mostly on custom roms this shows up when there is STRONG 4g signals
3g shows up all the time even though if a stock similar device such as another mytouch or a g2 shows H.
and edge/ gprs is self explanatory.
some roms may come with kernels that may have botched LIBS that prevent 4g connection (ie cooked roms from european phones like- desire HD etc...). get a friends phone that is similar IE a vibrant 4g, g2 or a mytouch and run speed tests using the OOKLA app on market. You will get the same results when his **** shows H and when your **** shows 3g.
Oh and they and you will be surprised at how much cell carriers lie to us about coverage
I live in North Houston and I can get full 4g speeds 2% of my usage times per month
I did this the other day with similar WHITE MYTOUCHES, one was bone STOCK no root, and one was root with cm 7- royal ginger 1.5

I live in Orlando Florida so my 4g coverage is beyond great lol. I had the galaxy s 4g and I never seen 3g on it. I kno this is a older device so 4g won't be as great as the sgs4g but it dosent mean I shouldn't pick it up at all

This is weird. I speed test on full 3g nd I get 9 dwn and 2 up. So its 4g just no Rom will say h

Call it dial-up, call it hand signals, call it morse code. If you are getting 9 down 2 up you are making 99% of t-mobile users jealous. Simple as that.
Lol... I have to drive 1.5 miles just to get cell service to make a regular cell call. Wifi calling is the only way I can use my phone.
Living in the woods at the base of a mountain kinda kills your cell reception.

Yep my speeds are 4g on the my touch even though it never says HSPA just UMTS. But on speed test my vibrant is faster not sure why.
It seems like the 4g issue is with custom roms not the stock rom. I flashd stock with root and I never seen 3g only H the whole time

Better signal unrooted

I bought my ns4g about a week and a half ago coming from a tbolt on Verizon. I got it at 8pm and had it rooted by 9. I immediately installed cm7 and have been using every nightly. My signal was horrible. I had nothing at work and barely one at home. It also would barely hold a wifi signal even when laying the phone right next to my router. I've updated my profile and manually put prl 60679 on the phone and nothing improved. The only time I could get 3g was using the Verizon hybrid prl ( I don't have 4g here). I called sprint and updated the msi? And the lady said I was in great coverage at work and good at home. The signal was so bad in 4 ours of the phone sitting in my pocket doing nothing I lost 50% battery everyday. So this morning I unrooted to take the phone back to sprint for an exchange. I've been using it stock for about an hour and now wifi is good even outside my house and I get 2-3 bars most of the time. Is there any reason why this would be? I have owned about 90% of Verizon's android phones so I'm not new to this, I've just never seen this kind of difference between stock and rooted. I think I will wait and see if it stays like this or gets worse now and switch to the 3d if it is still bad. I switched to the nexus s because I love plain android, butit was so bad before I couldn't even make phone calls or send text unless I got lucky and it would connect.

the only thing i know on the subject is i left my phone unrooted for a couple of days. never noticed a difference after rooting. seems to be many conflicting reports on signal issues when it comes to the nexus. i have generally lower signal (3g 4g wifi) than my evo. really hope its software related so i can get a fix.
Rooting doesn't affect the phone's radio.
Maybe the ROM was bad?
ive been watching my signal strength for a day and its usually around -86. my evo was always -90 or more
It could be the rom I just don't get it. I've never had a problem with cm7. I'm going to root and fund it stock rooted and see then maybe go with something else

damn i like soju 2.6 too. oh well stocks not bad either. i see theres 4 kernels to chose from and 2 are experimental
ok so i flashed my "out_of_the_box" back up and updated prl and profile and my status numbers are the same. i did notice tho that with soju 2.6 i was on evdo rev 0, and now back to stock im on rev A
now wtf? after i flashed a netarchy kernal (stable bfs 2.3.4) im on rev 0 again. what going on here?
Here's what I'm gauging my claim on. I live in a basement apartment so I get awful service anyway. But, on CM7 I can't make a call without it dropping, and mms is out of the question. On stock, I can almost always get through a call and mms sends no problem. I have an airave and its the same story on that. CM7 the mms just sits there with the icon spinning forever. Stock it sends almost instantly. I keep a backup of both and just switch between depending on what I'm doing.

My favorite quote "Engineers are educated beyond their intelligence." Ironically, I am in school for engineering
Now I have a problem. I rooted again and right now I am stock rooted. My signal is back to being bad again. So I can either remain stock or switch back to Verizon or go with 3vo. I came to sprint just for this phone so I can root and play. I don't know what to do. I have 18 days left until my 30 is up...
Sent from my Nexus S 4G using Tapatalk
I rooted a couple days ago, haven't noticed much of a difference in signal strength practically... BUT my time without signal went from 1% to about 8% . Obviously battery life suffered somewhat.
Currently I'm on EvDO rev. A.
Will continue to post updates.
So I have switched to the hybrid 00001 prl for now and I get decent signal, eve get some at work. I figure if I'm going to switch tithe 3vo in a week I won't go over the 300mb roam limit. Its a shame too I like this phone, I just want something j can play with.

EVDO rev 0 to rev A switches depending on signal quality.

Reflashing radio after flashing rom

I have been having bad signal and sluggish data speeds after flashing a rom. On any rom I was choosing actually. And then I decided to give it a try after almost 6 months of being rooted to reflash my current radio and I noticed immediately the difference.
Is this a known problem or am I the only one? I know flash my radio after every rom.
Sent from my HTC Glacier using xda app-developers app
Your radio is not altered when flashing a new ROM. By reflashing your radio after every ROM flash, you're only increasing the possibilities of something going wrong and leaving you with a brick. The radio is the most dangerous thing to mess with and radio flashing/reflashing should never be taken lightly.

But why is that I get signal drops and slow browser on every rom even on stock rooted
Sent from my HTC Glacier using xda app-developers app
Your ROM does not touch the radio. The radio resides in a partition not touched by recovery.
Flashing a radio is dangerous. Failure = a bricked device.
I'm not sure why you're having this result, or if it is a placebo effect. All I know is ROM does not affect Radio performance
But I do notice a big difference in the time it takes to load a web page after reflashing my radio as well as no more signal drops

Shaky service in your area? Is WiFi like this too because it might be the hardware
Sent from my HTC Glacier using xda app-developers app
Nope wifi is perfect, my wife has a sensation 4g which never has a call drop and we live in the Miami area and I would get call drops in the middle of the day in the city.
It happened on virtuous affinity (but I know sense 3.5 has kind of a problem with signal, correct me if I'm wrong), virtuous unity, lee Droid the latest one, everything. Until reflashing my radio I don't understand why.
Sent from my HTC Glacier using xda app-developers app
In Miami too... I just reflashed to the latest GB radio from Panache stock and it did feel like it was giving me better overall service. On Sense Roms though I do notice an occasional signal loss and then it comes back and a lot of times it's while sending SMS. After the last time going from Dark Unicorn back to ARHD I was not receiving some messages from my g/f and she wasn't getting some of mine, if I did they were late (that didn't make her happy, lol) but I think it is better now. Maybe it's T-Mobile, maybe my Android doesn't like her iPhone.
Actually I just flashed the latest version of miui.us v4 and I can say that it has the best signal on any rom I tried and didn't have to reflash my radio as compared to just changing from the last GB version of miui.us which needed a radio reflash

GS4 data very sporadic

My s4 data is bad to kick off and back on. It has done had since I first got it. I have 3_g at home and it's very solid signal, I never lose signal in fact i keep 4-5 bars but data kicks in and out all of the time. My old phone was very solid never lost data signal ever. I have tried the 3 different radios and several ROMs but they all do the same thing? It doesn't show roming and it looks to be on sprint solid. I know I've read about losing data due to flashing but mine works fine then it doesn't work, off and on, off and on all of the time... Rebooting sometimes brings it back, switching radio off will sometimes too but sometimes I just have to walk away for 10-30 min and it'll pop back up... any ideas?

I will assume that you have updated PRL and profile. If not, do so. If that does not solve the issue, call Sprint to see if thry are working on towers in your area.
Yes I did update profile/prl as well. I have a second phone we keep in the house (as my house phone) but it keeps data signal just fine never drops either. I haven't called Sprint I may try that but I really think its buggy firmware

Hope the problem works itself out. One last suggestion would be a factory reset (that is if you didnt wipe data through rom flashes). Doing so can potentially fix a lot of different isses....maybe this as well. Good luck
