2.3.3 upgrade kills hsdpa connection, 3G only now - Galaxy Tab Q&A, Help & Troubleshooting

Greetings all!
I got my GTab last month and it was working pretty well. I had experienced the odd freeze but otherwise everything worked fine.
I finally got Kies to work on my Win7 Starter (Samsung hehe) netbook and saw there was an update. So I did the update and now I cannot get a HSDPA connect and only 3G. Seriously annoying to be so limited because it seems an update killed a rather important connection for me
So, where to go from here? Do I try to find out how to return to stock or does anyone have any suggestions for troubleshooting/fixing this issue?
I have played around a lot with my G1 and flashing ROMs so I am reasonably familiar with flashing and ADB. I'm good at following directions
Any help would be greatly appreciated.

Greetings! Welcome to Galaxy tab forums
Can you give me more info about your tab? Dial *#1234# and perhaps tell me your tablet model please? Who is your provider?

Thanks for the reply!
Now we get interesting.
PDA: M180S.TE.1719
PHONE: M180S.EE23.1008.ST
INAND: EA26
I am in South Korea (but I am Canadian) and my provider is SKTelecom.

You said that you lost HSDPA after getting the South Korean GB update right? Maybe check your APN settings? Try googling them by typing apn <enter operator and country here> or ask you operator to give them to you by calling their customer support. Most common reason for losing connections after firmware update is wiped apn settings.

Y'know, it's amazing how techincal problems look big and one looses such oversights.
Ok, will be checking into that tomorrow morning.

That's not entirely true.
The International Telegraph Union(ITU) has stated, regarding 3G service:
" It is expected that IMT-2000 will provide higher transmission rates: a minimum speed of 2Mbit/s for stationary or walking users, and 348 kbit/s in a moving vehicle."
- http://www.itu.int/osg/spu/imt-2000/technology.html#Cellular Standards for the Third Generation
According to release 9 version of 3GPP TS 25.306, you could get a max of 46.7Mb/s (more depending on hardware/other factors).
Despite all the technobabble, I have noticed a HUGE difference/drop in my network performance.
So yes, there IS a speed difference for me. Maybe where you are the implementation isn't the greatest. South Korea is difference, much more closer to the edge
As far as my problem goes. I have to visit a service center to see about either fixing or downgrading the OS. The store guy, while very nice, not overly technical.
Will let everyone know how it goes as soon as I get there.

3G not working with HTC shipping ROM?

Firstly, let me thank everyone who does all the SUPERB work on this site, developing software, ROMs, and tools that us normal users would otherwise never see...
Here's my problem:
I got a Kaiser with the shipping AT&T ROM on it - I'm in the US.
I wanted to get rid of the bloatware and other crap that AT&T puts on the device, and take it back to an HTC ROM.
The problem is, I can only connect to the EDGE network, and I'm only getting 40-60k transfers - I know that with my Samsung Sync (my previous phone) I was getting 1.3-1.5Mbps using the same site to test (http://text.dslreports.com/mspeed)
Is this a limitation within the HTC ROM? If so, does anyone know if newer HTC ROM's (perhaps even with WM6.1) will fix this problem, or do I HAVE to use an AT&T ROM to access the 3G (HSPDA) network in the US?
Thanks in advance for your time!!!
Do you see the icon 3G and it changes to H once you're accessing the internet? If no, you might want to check if you correctly config the connection.
I myself don't trust http://text.dslreports.com/mspeed when it runs on PIE web browser. I did the benchmark on 2 different types of connection, at&t HSDPA and Verizon FiOS* Wifi, and it comes up nearly the same speed 1.3-1.5Mbps.
*I have 15 Mbps download package.
Yes, it DOES do that (Mr President...lol)
What site do you prefer to test the speed of your 3G connection? I was hoping to use Speedtest.net, but doubt that they support mobile.
So, I guess that you're saying my connection is probably just fine, but that the site is problematic?
Thanks for the quick reply, btw!!

I don't pay attention too much on speed. But, there are many ways to confirm that you're connected to 3G network.
If the answer is yes for any question below, then you're 3G.
a. Tethering internet via your PC on "internet sharing" mode and make a call at the same time.
b. Stream any audio broadcast with bitrate above 196Kbps.
Enjoy.
Um, where do you live? Pretty much only the major cities have 3G deployed, and even then, it's no guarantee. I live in Minneapolis where 3G was rolled out last November.

I'm in Pittsburgh - I know for certain that I'm in 3G territory, as I just got the Kaiser a few weeks ago, and before that, was using a Samsung Sync tethered to my laptop, and getting 1.3 - 1.5 MBps....
UPDATE
Must have had a lousy signal where I was trying it before - I tried it again, using the same site, and was getting 500-600k - so I guess it's hitting the 3G network, but for some reason, changing the 3G icon to an H, presumably indicating HSPDA.
All's well...can one of the mod's please lock this thread? Thanks!

[Q] Changing the Radio Frequencies on a Samsung GT-I9000

Phone Radio Compatibility Details Requested (both general and US T-mobile specific)
I have been doing a lot of researching regarding this phone and all of its cousins as well as how they will operate on the various US carriers. I have the following requirements for my next phone purchase:
1) Must be an Android device
2) Must have front facing camera (for international video calls to relatives)
3) Must be GSM (for compatibility with local prepaid SIM cards when traveling)
As AT&T and T-mobile are the only two carriers in the US (the only two viable ones at least, I don't know if any smaller carriers use GSM) and I refuse to renew my contract with AT&T that narrows it down to one option.
I have been researching the different carrier frequencies, both what they are and why they are different. It seems T-mobile decided to be special and as a result it is nearly impossible to get a T-mobile high speed compatible phone unless you purchase it from them directly. I almost want to call that evil, but it is easy to believe that is just a bad side effect rather than the intent.
Anyways, as we all know the Galaxy S has been severely nerfed by everyone except for Sprint. If Sprint only had a GSM phone that I could use internationally I would pick up their model, but alas it is not. I will not purchase the Vibrant because it lacks the front facing camera. My last option is the unlocked Galaxy S available abroad unless I am missing something.
Most of the online retailers I have seen all list different band frequencies and not even all of them have it divided into 2G/3G frequencies. I have some specific questions, but if you have any useful information for me I would appreciate it.
Question 1: Do the online retailers just suck, or are there truly many different frequency bands for the unlocked Galaxy S?
Question 2: Does anyone know of a Galaxy S phone that is fully compatible with T-mobile in the US (not the Vibrant, I need the front facing camera)? If not, would it be good enough?
Question 3: The radio bands I have ready about are usually divided into 2G and 3G categories. Is the phone radio physically divided into one for 2G and another for 3G, or is it the same radio and those are the frequencies USUALLY used by the different speeds? If I see the appropriate T-mobile high speed frequencies listed under 2G, would that mean the radio is in fact compatible with the T-mobile 3G because the radio can talk on that frequency, or is the hardware actually different and unable to comprehend the 3G speeds?
Bumping my own thread and also wondering if anyone has any recommended vendors to buy the international Galaxy S in the United States.
i bought mine from handtec.co.uk and it is working ok..
beware though that at&t unfort. in my error has been slowly getting rid of 1900 3g and more 850 3g which does not work on the phone..
at least at home the microcells are 1900 3g.
Radio chip/antennae changes?
It seems the internal Galaxy's electronics is all the same or modular. Is there a chance to take the radio module out of T-Mobile body and put it into the Sprint's nice hardware? How easy it is to obtain the desired component?

[Q] Which CSC (Phono/radio) version will give the best results?
I'm wondering what CSC-version (Or is it the Phone/Modem?) will give the best results in The Netherlands with Vodafone as telecom provider, or maybe... where can i find the stock version of the radio (and is it possible to use it with a root?)
I'm using Froyo (I9000XXJPC) - Rooted, but I'm wondering if my connection isn't worse since updating, I believe my 3G/HSDPA is weaker since then.
Anyone the same problem?
I also have the same problem, but already since upgrading to jm1 trough KIES.
I think we need a i9000XEN CSC.

Is the "i9000XEN CSC" the stock one?
I'm not on JPC but changing from JM3 to JP2 (modem) actually makes my GSM signal and wifi sort of worse, dropping 1-2 bars at the exact same location compare to JM5
CSC has NOTHING to do with reception or 3g whatsoever... its just branding stuff and APN etc...
the MODEM file is the one you need to look out for!
Right now i'm on JM1 (rev03) with the appropriate modem file and i have no problem whatsoever!

You sir, are wrong.
I have a Bell I9000M and flashed the new HK JP2 Froyo to it. I lost my 850mhz UMTS Band. I then flashed back to stock JH2, including the modem and still no band. The only thing that fixed it was doing the *#272*xxxx# CSC select. Once I did that, bingo, 850MHZ Reception.
I know what you're saying SHOULD be correct, but unfortunately, it is not.
I'm still correct! CSC contains carrier costumizations. Which also can contain settings to ENABLE the 850mhz radio band!

So, enabling/disabling a band doesn't have anything to do with reception?
So, when I get no reception because I'm in an 850MHZ ONLY area, which is disabled by the CSC. The CSC has nothing to do with it? I don't see the logic there, but alright.
You can use whatever CSC you want as long it enables the 850MHz band. It doesnt matter what CSC...
Modem file is the one that contains the drivers for the radiochip etc... A better modem file means that you can get higher 3G/Wifi speeds or even have better reception.
The CSC only contains the setting to enable the band.. nothing more nothing less

Which was wrong. No service due to CSC = No Reception. Plain and simple. You can argue what you meant all day, it's not what you said.
I'm done with this. I apologize to the OP for having this thread turn into this childishness.
Have a good day.
BackfireNL is right. Selecting a CSC indicates which band/frequency the radio will use according to the place you are.

Uhh, that's what I said, disagreeing with his "CSC has NOTHING to do with reception" comment.
Just so you two know, the actual Merriam-Webster definition of reception is:
"the act or action or an instance of receiving"
CSC not allowing 850MHZ = No Reception.
If you're taking about small increases/decreases in quality of reception, then absolutely yes, CSC has no effect. But that is not what was stated.
Confused...
Okay... thanx, both of you!
I've learned a lot new thinks...
Finally... I understand that I must use the Modem file if I have issues with the reception of the 3G network, but which version should give me the best results for my provider (Vodafone/Netherlands) and the new Froyo (JPC), and where can I get that modem file?
The Radio Chip in the SGS
ht tp://ww w.triquint.com/prodserv/more_info/proddisp.aspx?prod_id=TQM6M9014

That is the chip, now if I understand that right, it is a Pentaband radio. So that would mean it is all locked out in software.
No?
Users in the U.S., What Radio are you using?
I am running CFLagFix1.60(StockXXJF3) and using AT&T.
Everything works fine, except for a weak signal.
I can receive and make calls, but at times have calls dropped.
My home is in an area where there is a weak signal.
I am not try to get 3G, just a stronger signal.
May not be possible, but worth a try.
Signal is fine when not at home.
I have tried the following Radios without boosting the signal.
MODEM_I9000XXJF3.tar
I9000UGJH2-Modem
MODEM_I9000XXJP2.tar
bell_I9000_radio - No signal with the bell_I9000_radio
Any suggestions, or is it a lost cause?​
Is this a haiku?
PS It would help telling us what carrier you are using it on.

In need of instruction...

To give a back story on what I'm trying to accomplish, I'll explain my situation.
I work for Bell, in a retail store, the main reason I came to these forums was to find a way to re-flash phones in store to avoid having to doa what little stock we have of the phones. One of my colleagues from another location told me about the new update from Kies locking phones up at a ridiculous rate of 25%, so I'm trying to be pro-active about it.
Once I got in, I got a bit carried away with 2.2 software and what not. Now, i'm no expert, but I'm computer literate and made sense of most of the process, some extra guidance would be nice though.
Playing with the phones we have in store, I was able to flash every available software I could find on said phones, however a constant issue is found. I can not get a solid data connection. If I disable data, everything works fine, soon as I turn it back on, nothing happens.
Furthermore, I followed a thread regarding re-flashing everything back to Bell's stock settings and it didn't help me along at all.
I have done some searches, but i'm coming up dry. I know you've probably heard this hundreds of times and I'm sorry for being new to the process, some guidance towards this all would be great.

not sure where you got that number from, but it's not that accurate
the reason for the ridiculous high amount of returned phones is due the Internal SD card problem that was found.
even under normal conditions if it gets formatted a lot or used a lot it seems to die faster than its Europe counterpart.
apparently on the Canadian version of the I9000 they use a bad batch of Flash Disk for the storage memory
there is a sticky Topic Poll about it.
it is NOT the ROM flash from Kies that are killing the units, just anything software that constantly access the internal SD can produce the same effect.
http://forum.xda-developers.com/showthread.php?t=793404
the rest of the returns you guys at Bell are seeing are due this other problem discussed here http://forum.xda-developers.com/showthread.php?t=775017
it can be reproduced, but you need the ideal conditions to do it.
it has to do with signal quality and tower availability

I'm referring to 3G connection. I have set up the APN, even tried different settings, all producing the same results.
In regards to your second reply, the phones I've seen at this location for DOA's have mostly because of a failure to fully turn on, the display won't show. I've experienced similar issues when a flash doesn't work properly, a re-flash fixes it. We started seeing this issue after samsung released the update. However, I'm not going to flash a customers phone to have them lose 3G connectivity, or open up other issues.
Basically, I'm looking for two things. Primarily a way to re-flash everything to work as if it were out of box, with the latest software update. Secondly, to be able to get a stable 3G connection on 2.2, everything else seems to work fine at this point.
i'm not even going to touch the 2.2 topic as it's not even released officially.
the current stable official flash is JH2, on JH2 3G should work properly (stable), another thing you can do is to go into the service menu using the secret codes (wiki) and make sure the proper 3G bands are selected for WCDMA
1900 and 850 should both have a start next to it
next check is the *#0011* to see if the towers keeps constantly changing
that's another reason for unstable 3G if the phone keeps jumping towers every few seconds
this is also related to the 2nd link i mentioned about people getting Comatose Syndrome on the phones, which locks up the phone, and they have to reset the phone to get the phone to work again.
I'm running JH2 currently, I ran *#2263# 850 and 1900 are available. Also, ran *#0011# both are available, ran a test on youtube it worked for 5 minutes.
Any ideas?
**Edit**
I lied, on the *#0011# it only shows 1900.

Get something straight
the update samsung released was JH2, and it is not causing the problems you've seen.
the problems with the symptoms described are after they were flashed by the Alpha & Beta versions of Froyos 2.2, which many of them do end up losing the 850 band, the band issue can be fixed with much work.
there have been at least 4 different leaks of froyo, each one bringing its own volume of chaos and bugs, the most dangerous 2 are JPH and JPK, one loses the IMEI / ESN number ID, the other one kills the internal SD

Since the I9000M and I9000 are hardware based bands, you should always have the 850 and 1900 bands for 3G
Many who have tried Froyo and back had come across the problem of losing the 850 band, mainly because the Froyo leaks were intended for the Korea test team running international I9000 devices
some times just by flashing the Firmware back to stock or Froyo betas doesn't actually activates the 850 band, even though it shows as selected in the Service Menue
if you go back to the Band Selection screen of the Service Menue, you should choose bands that are knowingly not available in canada, like say band 900 for example, and then go back again to the service menu, and band selection to only choose 850
once you can confirm 850 works, then you can select 1900 as well, and now both of the bands should be active permanently until some body else screws it up again.
using *#0011# and trying to call the voice mail are the fastest way to verify for line and for 3G on 850
you can also try the app speedtest from speedtest.net

[Q] HELP UK model with serious signal issues on ATT in the USA

Hi all, well my One arrived from the UK today.. As I feared it does not have the ATT LTE bands that PDAbd.net suggested it had, bummer, but I can live with HSDPA... Set up the phone, it asks me to select the operator I am unsing, with ATT as the first choice... all goes well.. I load it up and initial impressions... WOW.. what a great phone.
BUT and and very BIG BUT.... the signal is terrible... bouncing from no signal to 2 bars and displaying H one minute, 3G the next and then E...
Driving down a notorious road it drops the call at least half a mile before typical and doesn't pick it up again until even later..
Does anyone know if there are any setting I can adjust to optimize to ATT?
I really do not want to put it is back in the box, but unless someone has a suggestion for me, I have no choice...
Help!!
Many thanks,
Nick
A quick question. Where did you get your HTC One? And have you used any other HTC Phones before and got good signal with it?

Hi There,
I bought it in the UK. It was a legitimate HTC supplier and an unlocked model 801n.
I have used a couple HTC phones in the past:
ATT 8X - worked well (at least as far as signal was concerned, but that was the ATT model)
I also had a Verizon Incredible, but since that is a different provider, I am ignoring it.
Other phones I have right now adn tested in the same location with the same SIM:
1. ATT - Galaxy note 2 - good signal no issues
2. ATT LG Optimus G - Good signal no issues
3. ATT Iphone 5 Good signal no issues
4. ATT Nokia 920 - good signal no issues
5. Blackberry Z10 - unbelievably good signal - no issues - Unlocked ATT bands, not ATT branded (Purchased from Expansys USA)
This is why I am wondering whether it is some kind of optimization issue. I cannot believe HTC could have made such a mistake in design. Also, if I switch to GSM only, I have full bars.... It is only on 3G and HSDPA that the signal is poor and the display oscillates between 3G and H
Any advice?
Many thanks,
Nick
Are you rooted? The solution is disabling fast dormancy on HTC One. New HTC devices enables fast dormancy by default which affects & weakens signal strength on networks that doesn't support it yet. If not I am not aware of any ways to disable it without root yet. I'll update you if I find one.
On UK almost all networks do support fast dormancy already except for Three UK so that maybe the reason why it's enabled by default in the US however I am not aware of the implementation of network carriers there sorry.

Also, I have been led to believe that the One supports a number of carrier frequencies, but they only enable those for the specific region it is sold in. Do you know if there is a way to enable the other frequencies? Or is this just an unfounded rumor? Also, do you know if there is a way to check which LTE band the phone I have is equipped with - Not an on-line reference, but a way to find it on the phone?

Your warranty if you mess something in the software's side like bricking your phone & OTA updates. But you'll be able to update anyways just by directly flashing on the phone.
Anyways here's a noob proof app to rooting. Please do some research first before going so you'll not mess this up.

Also, I have been led to believe that the One supports a number of carrier frequencies, but they only enable those for the specific region it is sold in. Do you know if there is a way to enable the other frequencies? Or is this just an unfounded rumor? Also, do you know if there is a way to check which LTE band the phone I have is equipped with - Not an on-line reference, but a way to find it on the phone?
Many thanks!!

Check this regarding what is Fast Dormancy and tell us if it works(probably NOT (it works only to samsung phones) but it is easy to try) http://androidforums.com/samsung-galaxy-s2-international/674208-fast-dormancy-in-nutshell.html
"To turn FD on/off enter *#9900# in the dialler to get into the SysDump screen then select the Fast Dormancy option"
You mind sharing the link if they have stock? Good luck with the signal issue.

I had a friend with an international GS2 with the same problem. Constantly bounced from HSPA+ to 3G to EDGE to no signal. I'm 99% sure that the issue is network settings, you likely need to check SIM card, data plan provisioning, APNs, etc.

Thanks for the suggestion... As soon as I enter the code, I get an error, so I am unable to even get to the SysDump

I bought the last one they had. You should be able to find them now... More and more are popping up every day.
Many thanks,

Hey, thanks - Do you know what settings I should use? I have an LTE provisioned SIM card...I assume that should be ok, since the phone is LTE enabled, just wrong bands? I have tried with Auto LTE on and of - I currently have it on GSM/WCDMA - it has been working better the past day, but it is still not right..
The SIM works perfectly in the Note 2, Optimus G etc. So I am wondering whether I need to look at the APN or something like that, but I do not know what the best settings should be. Anyone have this info?
Many thanks,
Nick

APN shouldn't affect your mobile signal reception. It's just made for cellular data profiling. So you are able to connect to the internet.
How about try setting your network selection mode to manual and just select the top most usable network there?
Interesting... I am in Korea right now and have great signal... no issues at all. However, my data indicator is still bouncing between H and 3G, so that is very strange...
Despite the indicated low signal and bouncing data connection type indicator, the phone is working well, have not dropped a call recently and excellent phone call quality...
NO LTE connection in Korea though.. I assume that is probably due to ATT not having a LTE roaming data service agreement here? I believe my phone has at least one LTE band that it supported here.
Have fun..

I think u should talk to att people may be they can help? With the signal issue or the data connection issues!
Please let us know once u figure it out

Issue with At&t unlocked Moto X 2014. on t-mobile

So i am having issue. I bought a Moto X 2014 and it is clean in terms of imei. Both t-mobile says its clean and at&t says its clean. It is a AT&T variant XT1097 and like i said it is clean in terms of imei. weirdly enough T-mobile wont be picked up on the service, but AT&T will? it basically says
No Service
selected network (T-mobile) unavailable
and when i do try to select a network it says
"cant connect to network right try again later"
has anyone else have this issue with the AT&T moto trying to use it on at&t? and found a solution? if there is any solution ill take it i need all the help i can get lol
i tried reseting it, factory reseting, airplane mode, etc literally almost everything else.
Sorry.....I have similar issue..Did you find the solution? If yes could you share the info for it.

Add the T-Mobile APN.
it's discussed on the ATT thread, basically it's an issue with the lollipop radio used on our update, "fix" is here: http://forum.xda-developers.com/moto-x-2014/general/att-xt1097-lollipop-discussion-t2951294/page36
Add the APN (as mentioned above)
Download the 4G/LTE switcher app
select WCDMA preferred as network, only HSDPA speeds but it's better than no service ^_^
I had this similar issue and it was driving me absolutely insane, the connection would be weak then it would just disconnect me altogether and then zero service. Most of the time if I were to get a call the radio would switch to HSPAP like normal then after the call it would fail to switch back to LTE then it would just completely drop connection. This is on an unlocked AT&T XT1097 running on the unlimited MetroPCS (T-Mobile) mind you.
Since February 2015 I've been dealing with this bug by using LTE switch to get by, but this got so tedious and it just irked me that I had to go thru all this crap because of poor development. This is a pretty huge bug that should've never been there to begin with. Seriously, how dare you mess with my service Google?
Anyways what I did to fix this completely was just purchase MoFoRoot for $20 (fully worth BTW) and flash the 4.4.4 AT&T modem and now I have zero issues. I used to not connect to the network on a reboot but since flashing the modem I am now able to connect and stay connected without any hassle. The connection is now solid and I can't be happier with this phone. Currently on stock 5.0.2 non-rooted with 4.4.4 modem and zero problems, now I don't need to get another phone.
Using the fast.metropcs.com APN as the T-Mobile APN doesn't allow me to connect. I have solid LTE and HSPA/HSPAP service with it and can't be happier... I take that back, I'd be happier with better indoor coverage.
Thank you makers of MoFoRoot for your lifesaver app, I am happy to have supported your fine work.
