Lost 2g after flashing to JPC on Bell i9000m - Galaxy S I9000 Android Development

After messing around with the nvdata and associated files for hours to get my sim card recognized after the flash to JP3 I got my phone working with help from xda I managed to get hspa working but not 2g. So on the highway I can only use signal for emergency calls. Can anyone give me a hand with this please.
I had to go out of down directly after flashing hence not having time to figure it out.

Bell does not operate on EDGE (2G) network.

I must only be getting hspa then. It works in any of the cities but not on the highway.

Chances are you lost your 850MHZ band like happened to me.
Follow the instructions Here and it should work again.

I discovered the same thing yesterday driving from Edmonton to Calgary and back. I found Electroz posts and spent today flashing firmwares etc. I bought an unlocked version of the SGS and used Kies the first time to update. That was about 3 weeks ago and it applied DXJG4 which I figured, based on the revisions letters and numbers, makes my phone an Asian based unit.
I am guessing here but my hunch is that the DX version doesn't have the correct radios for Bell. I went the Bell site and checked my IME for compatibility and came back as a no go even though Bell has activated my sim card and I get my normal service etc.
Today I ended up flashing with WJM7 and used the Bell CMC. I followed Electroz #*272...... procedure....it was also part of the WJM7 flashing steps. With the Bell CMC the APN section had three different ones available but not the standard pda.bell.ca so I added that one and that is what I am using now.
The other three are AGPS, Browser and Tethered Data and are pre-configured. I had read a thread from a few days ago where a guy was getting charged huge sums of cash by using the inet.bell.ca settings and finally after fighting with them for a couple of days, bell tech support got him using the pda.bell.ca settings. They assumed he was tethering iirc. So I am leery of trying out one of these other APN's.
When I enter the service menu it is showing the network status as WCDMA 1900 Band 2. Is there another way to check the functionality of the 850MHz band without having to actually drive out of town to test it?
Thanks

Phone Keypad *#*#0011#* While viewing your band switch from wireless on then off from your top notification bar and you'll see it switch to 850 band before quickly going back on 1900 Band 2 when you hook back up to HSPA

Thanks Woolios. Tried it out this morning. All lot of numbers are changing in there when toggling the WiFi on and off but I can't see anything that indicates 850 being active.
I get a 3G briefly at the top of the screen but the line where the WCDMA and State are just disappear at that time and then reappears once HSPA connects.

Here you go guys, I had the same problem, this guy solved it for me, follow the steps it works perfectly.

+1 mkurzum is right about fixing the problem as I've goon through this whole step with flashing JPC and finding out it looked very nice but did not function with telus infact the only Wireless provider it would locate would be Rogers... Pft of all networks to come up lol but anywayz. The method I described about will tell you if your phone is switching from 850 band to 1900 or VS if your not seeing the 850 then your not connecting to it and should follow the above post. Don't forget to back up your apps

I have no problem getting my 850 to work on another build like jm6 when using a different csc/modem file. I am trying to get it to work with jpc.
None or at least very few of the key pad codes such the star-pound thing work with jpc on my phone.
It was the 850mhz that isnt working at least. But other then going out of town I don't know how to test it.

Australian Galaxy nexus bad signal and drop outs

I just received the galaxy nexus and got it from optus Australia, ever since geting it 4 days ago the reception keeps dropping out and data fails to work at optimal speed as it used to in my HTC wildfire or my iPhone 4, I've flashed android revolution hd , kang, and currently using foxhound and all have updated apns. Wonder is my device just a doggy one or is everyone else in Australia getting the some problem?

Try putting a different baseband on your phone. You should be able to find your countries carrier on the forums here. Just search.

LMAO! Rough man.
On-topic though, all good with mine on Telstra bud. Have you tried the latest APN at Ausdroid? Not sure if the Optus one has been updated recently... May also work if you try setting your radio to AUS by default, link and how-to coming shortly (I'll just find it).
haha im with telstra, brought it from optus.
do you happen to have any links to the baseband download? thanks.
I figured that as soon as I posted You should resurrect that Australian traders' thread in the MP.
- Go to the Dialer
- Dial *#*#4636#*#*, go to Phone Information
- Press MENU, "Select Radio Band" and select AUS2
- Reboot for good measure
This is supposed to optimise your radio to maximise use of the 850MHz band and stop it hopping off to 2100MHz in Metro areas.
Also use the following APN settings:
Name: Telstra Internet
APN: telstra.internet
MCC: 505
MNC: 01
Authentication: PAP or CHAP
APN type: internet
Some people recommend putting 'wap.telstra.com/wap' in the Server field. You should only use this if you need the Telstra portal, otherwise it just adds another link into the chain that isn't really necessary. TelstraOne will work just fine without it.
Let me know how you get on.
Yeh I've got same problem but after the update to 4.0.2 it got slightly better , I'm also on optus but got my phone from mobicity.
Its little annoying.

Not necessarily. Perhaps flashing the DVKK6 baseband (Telstra) may help. Unsure. If it has an Optus radio they may have done something to prevent it favouring 850MHz. This is just speculation on my part dude, it works fine on my Telstra unit. Perhaps this is one of the 'optimisations' Telstra made on their model.

No worries man, I hope it goes a bit better for you. I'm rural and getting 3.3mbps down, 1.2mbps up which is marginally better than my Galaxy Note. Considering I'm probably on a 5.7 or 7.2mbps backend, that's pretty good. No drop-outs either.
Good luck buddy.

Make sure you use the trimmed .img in post 6, not the one from the OP. Unzip it first (before you try and flash it) as it contains the MD5 hash also and this will stop the process (or worse).
Use fastboot to push it to your Nexus.
alright, thanks, it worked! thanks juzz! number 1 to come to! haha, ill see how i go with reception for the week. Cheers.

You may need to change your SMSC buddy. I think it's in the menu where you change the radio to AUS2. I'll need to look up the correct number for you once I get to work. Sit tight man
EDIT: Okay. Enter the *#*#4363#*#* code, then go into phone info. Scroll to the bottom, you will see a field for SMSC. Refresh the field, and see what it contains. Mine is this:
07911614786007f0
You could try putting this in if yours is different. Let me know how you get on.

That's fine. It will only handoff to GSM where there's no 3G. As long as you're on AUS2, preferred order is 850, 2100, GSM

[q] lumia 900 bell canada lte

Hi Everyone,
I wanted to find out oif any LUMIA 900 users in BELL are able to see LTE.
I bought the LUMIA 900 from ROGERS Friday afternoon and Saturday I paid 16$ to unlock code.
I went to bell and change the SIM card to be LTE supported. (I had a iPhone 3GS)
I successfully unlocked the phone an put the new card in,BUT I RARELY see LTE.
I mostly (95%) see 3G and YES I looked at the BELL LTE Map in their website. Even though I am currently located (work) within the area I never see LTE.
I called BELL Canada and they havent been able to give me much information.
Setting on my phone are:
Active Network: Bell
Data Connection: ON
Data Roaming Option: Roam
Hieghest Connection Speed: 4G
Network Selection: Automatic
APN: pda.bell.ca
User Name : Left empty
PAssword: Left Empty
Proxy Server: Left Empty
Proxy Port: LEft Empty
Any other Lumia Users with Bell Canada???
Your help is much appreciated.
You must call
Hi,
I had a similar problem with my Ipad 4G but i found the solution. You must call bell at *611 and get thru to tech support! Once you are thru tell them that you have an LTE capable phone and get them to add LTE Provisioning to your account. After they do that restart your phone and LTE should work. (It may take a while to connect to the LTE network)

Bell LTE is crap. Alot of areas marked on the coverage map for LTE dont work. Travel around the city and see if it works in other areas. For example, Keele and Steeles area in Toronto (not sure where you are) is LTE and I get my LTE signal there. If you still dont then try the above post.
Similar situation here with Telus sim. I get LTE but much more often phone sticks to 4G. In most cases i see only one bar signal. There however have been places where I get 2 or even 3 bars (woodbine and hwy7) only once I have seen 5 full bars of LTE - in the Weston Rd & HWY7 area.
I haven't called Telus about provisioning, all I did is to swap my SIM for a V3 LTE one.

Was yours Rogers too or AT&T?
Similiar situation here. Except I'm using the Titan 2 unlocked on Telus. They share the same networks at Bell from my understanding and same for LTE. I popped in my LTE enabled sim and so far I have yet to see LTE appear on my screen. I live 3 min Yonge/Dundas and work at Yonge/King and have never once seen LTE appear. You'd think being in the heart of the city you'd have LTE 95% of the time but so far nothing.
I tested download speeds and so far best I was able to get from Telus was about 5mb/sec. Not this 21mb/sec that LTE promises. Even on wi-fi at home with the top Rogers high speed plan I only got 9mb/sec.
Did you get the LTE provisioning?

Hey Pistol44,
The same thing I said above should apply to you! In most cases just getting an LTE sim card is not enough. You must also get you carrier Bell/Telus/Rogers to add LTE provisioning. I work for a company that sells Cell Phones on all the canadian carriers and I see issues like this all the time. A quick call to tech support should fix this!

I haven't called them for any provisioning. I get LTE on the Lumia but seldom and almost always 1 bar only. Interestingly the same sim placed in unlocked Sierra Wireless AC754, LTE holds consistently. Still 1 bar, but stays.

Thanks for the info and I did follow the suggestion. I spoke to Telus support and had a lady guessing all kinds of things for me. Clearly she wasn't familiar with Windows Phones in general. She had me try adding an invalid APN, then turning data on and off. She claimed there was nothing to provision on her end. Eventually I gave up with her and tried a hard reset. But still nothing. I edited my APN last night to isp.telus.com (only added the "i"). No change.
Then by some type of black magic LTE showed up today while I was at work and it stayed on my phone for about 2-3 hours even after I left the office. Well now I'm back at the office and it's on 4G again. Funny how I can be in the same spot where it's LTE one moment then 4G the next.
She probably did something!

I would not be surprised if she did something. It usually takes 16 to 25 hours for a provisioning profile to start working. Sometime they do call it something else.
I should also mention since then I've been getting LTE to show up about 75% of the time or more now. Sometimes it goes back to 4G and then I do a soft reset and it goes back to LTE in a few min. Not sure why but that fixes it.

LTE mode on an LT28i won't enable

I have a stock/generic LT28i from Asia. Totally unlocked and all. I'm in the US off and on, so I got a post-paid AT&T plan with data. 3G works great on my HTC One X (European version, meaning no LTE). I popped the SIM in my LT28i and 3G works, but not LTE. If I try to change the network mode to LTE/WCDMA/GSM, it instantly switches back to WCDMA/GSM. If I put my 3 Sweden SIM in the phone, I can set it to LTE/WCDMA/GSM and see [LTE] AT&T in the network search list. So it seems like there's some switch in the software that's forcing LTE off for my AT&T SIM. Any idea what's going on and how I can fix it? I was having issues with my phone bootlooping so I did a full reflash of the generic 6.1.E.2.29.
Is that account setup for LTE with AT&T?

You may need an AT&T 4G LTE compatible SIM card. I had the iPhone 4 with the mini sim and when I got my Xperia ion they told me I needed a new LTE SIM despite the fact that my then current SIM would have fit the in the ion (and they look the same, except my old SIM had the 3G logo on it).
Maybe you current sim is att 3G.
Same thing happened to me a few times. Kept switching to wcdma preferred. Try clearing cache, dalvik and reboot. Eventually I did get it to stick. Also when this happened to me Rogers network was having an lte outage, so that might have had something to do with it. But persistence did pay off in the end.
And yes you obviously do need an lte sim and the lte apn's for whatever network you're on.
Is your APN set correctly?

Ah sorry, I actually gave up and put the SIM in my One X (HSPA-only version) instead. 3G was good enough for my needs. Maybe on my next trip to America I'll put more effort into it.
having the same issue
I'm having the same issue, built I'm on net10, which is supposed to support lte speeds, but i don't get higher than 3g for their att compatible service.
Also, unable to root after phone overheated and did original gb att to gb lt28i, to ics.. the rootme or e4root neither one would work. I've got backups, but they're under titanium backup and cwm, of which neither can i access without root. Is there an .ftf firmware prerooted on ics that doesn't require anything but flashtool to install and add cwm, since I'm sure I'm not the only person with such an issue. If I've overlooked it, direct me to the page where it is, all I've found so far is stock roms, and deodexed, which i can't use.. Also, my boot loader is locked.. I've checked all threads about root and ion, and noon have been helpful with my recent issues..any downloads needed to rectify this and not the usual I've already done that loop back to the same popular pages would be helpful and appreciated. Thanks in advance.
EDIT: sorry, i didn't see how old this thread was...and to the above, i'm not sure if what it wrote applies to your network...but most likely you need to look into APN settings required by your carrier...

I know the ZL (6506) is capable of working with T-Mobile's new LTE network, but my question concerns the IMEI number and your account with T-Mobile. On AT&T, your account has to have an IMEI number that is known and recognized by AT&T so as to enable LTE connectivity. Is this also the case with T-Mobile??

The info or where you got your info is incorrect. you DONT have to have a IMEI number that is known to AT&T to have LTE. I have changed phones prob 20 times since I got my first LTE phone and NEVER had to change it again.
You can be on the LTE data plan and everything work fine on a old dumb edge phone then put the sim card back in an LTE device and it still work fine...
LTE worked fine on a Canda Note 2 and One X
Same here. TMo does not care. I just started using my ZL teo days ago, before that was Nexus 4. Just took the SIM from the N4 and inserted in the ZL. All works!

Hey people, I'm seriously considering picking up a Sony Xperia ZL C6502 Black. I'm aware that it doesnt support LTE on either network, but the price is insanely lowwww! My question is, does anyone know what kind of speeds I can expect to see on TMO and ATT respectively? I'm currently using an ATT Gnote 2 on ST/ATT and I have a Nexus 4 as a backup which I use on the TMO $30/"unlimited" data plan. I only point this out to indicate that I don't get LTE speeds now, which sorta makes it a "You can't miss what you never had" type of deal. I roughly get about 14-17mbs down on either device. Is there any chance I'd enjoy the same with the 6502 on either of these plans??? Any help/insight or even opinions, would be greatly appreciated.
The speeds to expect will be the same as you have now.......

i just received my ZL C6502 today and noticed that the data connection does not work at all. i followed the APN settings on the t-mobile link you gave and still no dice (it does show full bars and H+ as you mentioned and when i switch the SIM to my old G2X its on full HSPA+ speed). i left the house and it was running ok suddenly and streamed netflix, etc. but when i went home it lost the connection again. I'm suspecting that this phone does not really work on t-mo's 1700 AWS even though the box says so and that i only got online outside the house because that area is on the 1900mhz refarm. is there any difference to t-mo's AWS 1700 and regular HSPA 1700mhz?! any insight or help is appreciated!!
I have a 6506 on TMo so I am limited in help. However, someone in my office has a 6502 on TMo and it is working fine. He had trouble until he manually set it. Same case as mine.
Perhaps you have a defective unit? Try removing and reinserting the SIM card. Perhaps a factory reset.
I had mine for almost a month and has been flawless in LTE when in DC and HSPA in Dallas.

The 6502 is the same as 6506 but without lte it should work I don't have 1900 coverage and I'm always on hspa and there's no lte were I'm at either. U need to make sure the apn is set exactly there should not be any values under proxy and port also under apn type have it blank that was the issue with mine those three things had values and was messing up internet. Also there's three different apn you have use. 1. Fast.tmobile.com (Lte), 2. Epc.tmobile.com, 3. Internet2.voicestream.com. Give it a try.

thanks for the help guys. ive gathered all that info earlier and did try the three APNs different combinations / proxy - no proxy, etc to no avail. i'm leaning on faulty hardware or messed up radio. i'll just sleep over it but so far its been disappointing :crying: great phone though...
As a quick update I did literally sleep over it and I'm happily up and running with hspa.. I literally left the phone alone overnight lol. Rooted the fone and all I need is to figure out how to get to recovery to put CWM since pressing vol up at boot is not working and flashboot isnt going either (that's for another post). Moody bastard this ZL is.. Anyway Thanks again!

I have a 6506 on TMo without any issues. I live in LA without TMo LTE, but speeds have been as high as 18Mbps in West LA. I only have the issues of bad coverage at my house, but that's just TMo and not the phone.

The info or where you got your info is incorrect. you DONT have to have a IMEI number that is known to AT&T to have LTE. I have changed phones prob 20 times since I got my first LTE phone and NEVER had to change it again.
You can be on the LTE data plan and everything work fine on a old dumb edge phone then put the sim card back in an LTE device and it still work fine...
LTE worked fine on a Canda Note 2 and One X

That's the thing you had an LTE phone AT&T had in their system when your account was provisioned for LTE so you never had a problem after that. For those people that have the ZL as their first LTE phone on AT&T they will have to first get the account setup for LTE using a phone AT&T recognizes on their network.
So basically put the SIM in an AT&T LTE phone, have AT&T provision it for LTE then once that's done you can put it in any other LTE phone and it will work fine

LTE on T-Mobile not working AT&T working

So I got my pixel xl from Google today. It works but I am on T-Mobile and it will not connect to LTE band 4 or 12 which are in my area. I have an ATT SIM for my work which I popped in and it works fine. That said without driving around Atlanta to try to find B2 I cannot tell if it is T-Mobile or the phone. Is anyone else on T-Mobile getting LTE connection at all?
So news today I can connect to LTE. Yesterday when I got the SIM in using *#*#4636#*#* I would get zero reception forcing LTE only. The phone would only connect to UMTS/HSPAP. Today after several restarts and calling T-Mobile and Google support it is now working. Here is what I did.
First Google is saying the update is supposed to affect LTE connecting issues.
Second make sure your SIM is properly registered with your provider. They should elevate the issue to higher tech support to have them look into it. This takes up to 24 hours.
Third go to your dialer do the *#*4636#*#*, go to phone info and change the preferred network type to LTE/UMTS or LTE/WCDMA (I haven't seen a difference between them). (This info is in other threads) Then restart your phone.
The problem seems to be how the phone determines what bands the network provider uses. It defaults to CDMA as the voice connection. For me this meant the phone was always connecting to UMTS only. It seems the firmware has some kind of default setting when it senses an error out the gate. The APN settings and preferred network settings needed to be updated and the phone restarted for it all to work. I now connect to band 4 LTE in my area. I hope this helps others.
I am also getting slow data speeds on my pixel XL connected to t mobile
My XL seems to get pretty consistent LTE service and good speed on T-Mobile.
LTE in Chicago working well.

Google "Pixel LTE band 4 issue"
Weird. I'm getting pretty awesome Band 4 coverage in So. Cal. I also get Band 12 here, but Band 4 is what my phone tends to be connected to, which is fine since it tends to be significantly faster.
I'm in Oklahoma on t mobile getting slow connection compared to my friends. They each have a galaxy s6 edge and get between 70-80 MBs down sitting right next to me. I'm getting 14 MBs down. I just left sprint today for slow connection. Hoping to find a way to get this resolved ASAP.

I only experience the issue in downtown Toronto area and I contacted my carrier, Telus, in Canada. They confirmed that network signal in such area is mainly LTE band 4...
Just an FYI for those with the same issue. Google has asked for my shipping address after contacting them about the issue.

Have you tried swapping SIM cards?
I pulled the sim out of another working TMO iPhone6s and my PIXEL got LTE right away.
Have an update and updated the main post.

Thanks. I changed mine to LTE/WCDMA. Will know how it goes next week.
All seems to be working on my end.
I was having delays in mms being sent. I was using the default APN. About a week ago I changed the APN to the one recommended by T-Mobile. Mms sends instantly now just about. I don't think it's effected much on LTE but I didn't have problems before. Make sure your on the proper APN
I sure hope there isnt a recall..My XL hasnt even shipped yet and im on Tmo
I spoke with a t-mobile rep yesterday who helped me get my issue resolved. My main apn was set up incorrectly. Now I am connected to LTE and not just hspa+. I get generally good speeds most everywhere and I have tower right by my house that must go fairly unused.
