Lost 2g after flashing to JPC on Bell i9000m

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.

Are you sure its a GSM network? As far as I know, the galaxy s is incompatible with cdma networks. I could be wrong tho.
Sent from my LG-P930

Movistar in Spain uses GSM, not CDMA, but the bands are not the same for 3G, that'e your problem. You won't get 3G on Europe, only in the US with AT&T, Canada with almost any carrier, and any country from Mexico to Argentina.
Maybe in Australia/India you can have 3G, I don't know, but there are some members with a Glide from India, they can answer this better than me.

Thank you, I'm stupid, I should havechecked that before buying the phone

On the samsung galaxy s captivate it says:
Network Technology EDGE, GSM, HSDPA, UMTS
Does that change anything?

I think I may have good news for you, check this:
http://www.unlockit.co.nz/mobilesettings/settings.php?id=27
There's a good chance you have to set the APN settings manually, the above link shows you how to do this. These are the settings that tell your phone how to get onto the data network, if those are not already in the phone or set automatically. Give it a try, your problem has occurred more often and this was the solution!

Setting the APN manually should get internet working, but since the phone doesn't support the bands needed for 3G in Spain, that won't solve the 2G only problem. Still, working 2G data should make it at least fairly usable until you acquire a phone that supports your local bands.

Perhaps not in Spain then, but it works elsewhere in Europe. I live in The Netherlands and I get 3G. Haven't looked into the frequency bands, but it all works perfectly here. There are several other European users here, and I've never read anything about not having 3G because of frequency band issues.

[Rogers] Not allowed by SIM

My original thread has not been moved from the old forum, so I'm just going to link it here:
http://forum.xda-developers.com/showthread.php?t=1757711&highlight=not+allowed+by+sim
Anyway, someone on HoFo posted that if you change your APN to non-LTE, the problem goes away. I did that yesterday and so far I haven't seen the error. However, my coworker did the same thing on his S3 and still got the error. This issue is specific to Rogers network, as other people used their unlocked Rogers S3 on other carriers and did not see the error, but once they put in Rogers SIM back in, it was back. I wish Rogers would get off their ass and fix it!

This happens also on Telus. Not sure if I've done this APN trick, but I have HSPA locked and the modem locked on 850mHz through the service menu *#2263#, and I still get this error sometimes.
a quick flight mode toggle always fixes it.

Yeah, same here. It's just annoying when you're in a hurry and need to make an urgent phone call.

Not sure if this helps but I sell cell phones and a memo was released by rogers stating its a error in the firmware and that when rogers reception drops or its out of range it will say this, instead of showing no signal. Its states rogers and samsung are working on a fix for it. Its probably more noticeable on the rogers network than others because they are currently working on expanding there network in most of Canada therefore its probably causing signal drops every now and then.

still having this issue after OTA update
TELUS

Sorry to resurrect an old thread but I purchased an unlocked S3 about 3 weeks ago and I just got this error today. I was not able to make any phone calls until I used the flight mode trick. I thought this problem had been fixed? I'm with fido so it's part of the Rogers family.
Does anyone else still experience this issue?

haven't had this error since the last time i posted which was September
although i find it more often that my phone would lose reception in places or situations where before i would have reception, but just SIM error.
so my guess is that the phone hasn't yet reconnected to the network after losing reception (from underground parking etc) and before it was "showing" reception when it had none and came back with SIM error. now it just flats out says what's going on, which is no reception.

Need help on Tmobile

Got my zl today excited then let down by problems with internet, so i insert sim and it picks up tmobile and auto download settings then when it start downloading google play apps it hangs. I go to chrome loop up a page get "error 502 bad request the server could not resolve your request", i have full bars and H+ but wont connect. I also notice that when i insert the sim i can just pull it out with out pressing down on it. Any help...
UPDATE: Got it working just need to tweak the APN settings, for future tmobile user the automatic download setting are not correct here is the link for Tmobile settings http://support.t-mobile.com/docs/DOC-1979

Cool. I was using tue ones from the Somy app...

T-Mobile
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.
Sendt fra min ZL 6506

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.

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

[Q] HELP!!! ATT Galaxy S3 I747 unestable network or band conection

I have a ATT sgh-i747 4.4.2 KitKat unlocked and I use for Carrier Claro PR the connection to 4G lost in a few minutes from start up I can not do a call or use internet only wifi, I put apn from Claro PR LTE but nothing, I go to ServiceMode and in band selection are in Automatic I change to GSM all and works but in edge network for internet too slow but I can do any call, then I change to WCDMA all but not work I use WCDMA 850mhz only this works 4G, I use LTE all but only internet connection, what I can do to have all connection works including LTE. Thanks, if someone can help me will be apreciate.

Did it ever work properly on that carrier. If so, when did this start, and did you do anything to the device (flashing, modding, etc) just before it started?

HI Doc thanks for respond, I bought this phone used and phone have version 4.3 with PhilipTouch Recovery but system not have root or SuperSU then I flash stock recovery to use the update.cfg rename it to.zip and now are 4.4.2 stock rom official but in 4.3 same issue with network, I copy from my fathers phone att s3 NVfiles with QPST and I flashed to mine and put again my imei but nothing, what do you really think what happened in you're experience?

Im not really sure, but since you bought it used you should check to make sure the imei isnt blacklisted.
Does your fathers S3 work on the same network? Try swapping SIM cards. Test your card in his device and your device with his card.

My fathers phone is from ATT network, but I put my imei from my broken phone Galaxy s3 and is not black listed and is from Claro PR Network but let me see if my father give me again his phone because he don't want any body touch it and i dont know if is unlocked, I had to beg, and it was a miracle that gave me the phone to extract from his phone the nvfiles last time, you know if I can try something else DocHoliday??? Thanks.:good:

If you changed the original IMEI that's exactly why you are experiencing problems.
Anything but the original one assigned to the device will most likely cause problems. Even if its from another device that's the same model.
