[Q] using unlocked i9000 on AT&T....Problems

Repost from thread: http://forum.xda-developers.com/show...=771578&page=3
Hey Guys,
I have a GT-i9000 (Unlocked) and after a few firmware upgrades I have been noticing worse call receptions (more drops) and worse 3G data performance.
For example, I once had near perfect reception and few call drops along my drive home, now (5 firmwares later) I have been dropping calls like my old iPhone (actually worse) and what is more upsetting, yesterday my friends with their iPhones all had signal while I was getting the no service icon.
While i know the Captivate users can use the i9000 kernels (but swapping out the modem file) I wonder if anyone knows if I can use their Captivate modem file (JG8) instead of the one that comes with JM7 to fix my issues with reception and 3g performance .
What functionality will i lose? I travel to Germany often, will that cause issues with 1900Mhz and 2100Mhz bands ?
Is there any other reason that my signal would be so poor?? I really need help with this.....
Is anyone else using an unlocked i9000 on AT&T and having poor voice calls (signal/drops)?

What firmware are you using now? I would like to see if this relates to my issue.
I'm using JPC on my Bell i9000m and am starting to wonder if the reception is not as good as with JH2... I am contemplating using the JH2 modem file with JPC to see if it helps...
Coincidentally, I'll be in the US in a few weeks so I want to ensure I have good reception on AT&T as well.

i am using JM6

Just tried the modem from the the Captivate JG8, it would not even install.
So I am running JM7 now.
I will see how many dropped calls i get today.

JPC stopped booting for me and I am on JM7 as well - I'll post my comparative results as well tomorrow.

Just did some tests with my wife's iPhone (3gs) and my galaxy s.
Passing the same dead zone and her phone could make calls and mine would fail.
I wonder if i put it on gsm mode only if that would help.

[Q] At&t Tab Won't hold signal

So I purchased an LTE Galaxy Tab about 3 weeks ago and have been tossed all around by At&t customer service Samsung customer service and just about anyone else who could possibly know anything. I work for a retailer have have talked through my inventory director to an inside Samsung rep as well.
The problem is that whenever I drive further than say 5 miles (or 8ish km) the tablet will drop the signal and I will have to restart or cycle airplane mode to get it back. This happens regardless of wifi conditions or signal strength. I have tried 3 different SIM cards and also done an exchange for a new device. I haven't sold any of these to see if someone else has had this issue. Anyone else having this problem?

Nope metro Cincinnati and my Galaxy Skyrocket works fantastic. I actually got a little further last time and was able to stream video as a test all the way to work before it dropped off. (15 mile trip taking me right through downtown Cincinnati.) Of course when I got there I lost it.

May need to flash the modem again.

I dont really know. I have a system dump but dont know if the modem is kept within those files.
you could always just flash the stock ATT firmware again?

I've had 2 of them do this with and without root from day one. Is re-flashing really going to do anything?
Here is some more info. Samsung customer support told me to re-create the stock APN and see if that would work. Well the tablet won't stay on any other APN except the default. i have also tried a "pta" APN (like on the skyrocket) and the "phone" APN (just HSPA+).

I still do not know how to get FastBoot_SU working on my XT907 so these things are just experimental.

I know Edge and Voice is working with my Sim.
No idea how to get FastBoot_SU working so i did this a bit different.

1. Navigate inside VZW_XT907_4.1.1-9.8.1Q-27-2-4_1FF.xml using winrar or winzip and find the original NON-HLOS.Bin over write this with the Aussie Radio 100kb one. Make sure its packed normal again.
2. Use RSDLite, make sure Phone is in Debug mode, flash the new VZW_XT907_4.1.1-9.8.1Q-27-2-4_1FF.xml with the modified Radio.
3. Let the update do its thing, once done insert SIM and enjoy GSM reception.
4. Find a way to gain root access ahhahahaha bc this should wiped ur root access.
There is a way to use FastBoot_SU somehow but it does not work me ...
This is the same modification done to ICS to get it to work with US carriers, except you are on JB or in this case i used JB to flash the entire device.
Some one feel free to clean up these steps or improve this for easy use of tutorial ? You are welcome to edit LOL

followed the steps. but it seems the radio is problematic, because att signal is vey vey weak. I couldnot place call.the same micro sim had 4 bar at my hd2 win phone.
any fix?

Just tried flashing following your instructions and got stuck.
RSD Lite v5.6 Multi-Flash reports:
Failed flashing process. 16/19 flash "cdrom" -> Phone returned FAIL.; phone connected
Please help!!! Phone now stuck in Fastboot Flash Mode...
Thank you

I did not use 5.6
Also make sure ur battery is above 50% I did have issues flashing when my phone was at about 30-40 ish %
It will show up as low battery.
Get the Stock Verizon JB reflash it with 6.X and up.
Then use a clean version of JB with a modded PJcon Aussie Radio.
And reflash it from there.
To get out of there just Reboot by holding all buttons Power and Volume until reboot.

Thank you!
It only works with version 6 and above.
All is good now.
BTW I just traveled through the documented refarmed areas in Chicago and Cleveland and still no 3g.

yeah same here.
We still figuring out how to get 3G or 4G

Just to add some "fuel to the fire"...a year or so ago I got bored with my Defy and got an Atrix 4G online from the US (I live in Australia). It was AT&T branded and locked so had to purchase an unlock code. When I got it going on Telstra, the reception was just never that good. People always complained they couldn't hear me and I had similar experiences with hearing them. I even gave it to my bro on the other side of the country and he had the same issues.
I suppose what I'm putting forward is that even if it is 2100mhz band or 850mhz band which the Aussie radio does (I don't know what AT&T/T-Mobile run on), it's possibly more than that? I recall reading a VERY interesting article about how much work carriers do to get phones to work on their selected band - no disrespect to any Devs intended, this is just my thoughts as this may be a ghost we're chasing?
Or is the Electrify M XT905 going to work any better?

Works perfectly fine in Germany though Germany uses Stock Rom for XT907
I am getting Super strong signal everywhere better than my iPhone 4, I am using Aussie radio.
I even get better signal than the AT&T users. So it maybe the area, AT&T been getting worse bc they share some towers with T-mobile now.
By that the same tower rent space T-mobile is allowed to put up their Antenna gear, which sometimes decreases signal strength of AT&T.
Which happened alot in my area, alot of AT&T users loosing more signal... and running a modded phone is probably isn't helping the matter.
But T-Mobile seems to have few more frequencies after the refarm ? Maybe that's why ?

The XT907 Definitively is able to get H+ on GSM with Stock Rom in Europe.
H+ we managed to get it to 2.xMB but her normal area we only get 1.5-1.9MB ish
She also picks up E and 3G here and there.
This is on O2 Germany (DE) in Munich Testing to Frankfurt.
Using Stock Verizon Firmware un-modified stock radio.
I will test Aussie Radio next week in Germany see what happens.
But right now She is enjoying H+ with GSM on a XT907.

Hi guys,
I've read the threads in Q/A and this one about different sim cards in RAZR M, and I must say I'm pretty sad because it doesn't work.
I like this phone very much. It's the best phone I've ever seen. But I won't buy it because I don't have money to pay for expensive plans to Verizon (nor I will be in the US for 2 years which is the minimum contract time), and it doesn't work on T mobile which I would like to use. I guess I will have to stay on my Defy and wait for some new unlocked version of Motorola (never gonna happen imo).
Or should I buy it and try this method so I can use it partially with T mobile? Please advise.

I am using it with this method with T-Mobile.
Though when i am in Germany I have to take the mod out to get onto 3G in Germany.
With US-T-mobile we only managed to get Edge Connectivity so far.
I like it because i dont use much data and edge is enough for geting GPS to work smooth and surfing is slooow.
Else all is well =)

Thanks for the info~~~!!

It'd be really cool if the dropbox link worked. Unless im doing something wrong. Unless i can pull it out of another stock/rom file

Great info. Is the dropbox link down for good? I cant seem to find any mirrors :-/

This method has been made obsolete by the discovery of a much simpler procedure that edits a single bit in the radio NVM that enables full service on US carriers.
I wrote up the updated method in the Q&A section.
http://forum.xda-developers.com/showthread.php?t=2166542

Can someone please reupload AUSSIE RADIO as Radiocomm method is not working for me!

[Q] Weird Vodafone service issues

so I have this weird issue and i hope you guys are able to help.
I live in the Netherlands, specifically in Emmen, Drenthe.
A few days ago i changed my network operator from T-Mobile to Vodafone.
I did this because I wasn't very happy with T-Mobile's network, they do reasonably well in the west parts of the Netherlands, but in the East part, not so much. Vodafone seemed a pretty decent alternative.
Now i came across a problem, I study at Stenden, which is in Emmen, and nowhere else but at Stenden (and Drenthe College, another school right next to it) I have no signal. It's not all the time, but pretty much 90% of the time there i'm getting no service.
I have an (almost) 3 jear old GS I-9000, with CM10.1 on it. Seeing as it's so specific, I was really doubting it was because I'm using a custom ROM, nothing like this happened with T-Mobile.
Regardless, I decided to go back to 2.3.6 stock just to be sure, and apparently that fixed it. I'm getting an Edge (E) mobile connection at the points at Stenden and DC, and i can call people normally again.
I find it strange that i'm actually getting an E network anyway, but to think my connection previously was thanks to CM10.1 just seems weird. Not to mention my Phone is once again as slow as Peter Griffin during KisStock
LONG Contextual story, Now my question is this: what's causing this loss of service that's ONLY at college, and am i limited to stock 2.3.6 or can i use another ROM?
Any additional info i need to add?
Edit: FYI, My IMEI should have been fine when i was still on CM10.1, so unless i missed something there, it shouldn't be because of that.

That would have been caused from your modem. Flashing CM10.1 changes your modem to XXJVU (I believe, its been a while since I've used CM10.1) regardless of where you are I think. Try flashing in a modem that's Netherlands specific and see if that fixes your problem.
I think there's a slight chance that its kernel related as well but that's not really likely at all.
So try either flash in a Netherlands specific modem or the same modem as the 2.3.6 version you're running.

[Q] San Jose, CA: HTC ONE, no LTE at LTE tower and loss of BT audio

Good evening,
I'm an Ericsson(Sprint) tech (Since 2000) in the San Francisco Bay Area.
My phone is unlocked (Via HTC unlock), had TWRP 2.5.0.0 installed, and is running stock other than that. Rooted with SuperSU
I recently got an HTC ONE and found two odd things:
1. After flashing http://forum.xda-developers.com/showthread.php?t=2251788 , and Power Toggles from the Play store, my Bluetooth audio would go away. The call still connects to the BT headset, but no audio. A stock rom re-flash takes care of that issue 100%. Semi-noob lesson learned, back up BEFORE trying new mods.
2. This phone will not connect to 4G LTE. (more detail to come)
I have tried all the obvious choices: Reflash/Reset, make sure CMDA/LTE mode is set, even changed my LTE Next Timer to 5 from 300 in the ##DATA# screen. I even called employee care and verified that my UICC ID is properly set on the account.
Of course, the local store employees have no idea what to tell me.
I exchanged that brand-new HTC ONE for another brand new handset yesterday. It exhibits the very same exact issues.
This morning on the drive to work, it briefly connected to 4G LTE for a speedtest and I haven't seen LTE since.
For those of you who will say "Yes, but you're in a pre-launch market." I hear you. My response to that is that I physically work on the NV sites. I can take a cabinet key and open the cell site up to verify operation. I am testing this standing UNDER or a few feet away from a NV site running 1900mhz LTE, and my company-issued test LTE phone (different model) is picking up LTE no problem. In fact, I'm so close my download speeds are approaching 30mbps.
I've been lurking here for a while but wanted to see what the community thinks. Did I get TWO faulty handsets, or is there something I'm missing? I still have 1.5 weeks to exchange for yet another handset if I need to.
Thanks in advance for your time.
Disclaimer, these are my own opinions, and not those of Ericsson or Sprint in any way.

I'm pretty sure BT audio is a known issue in most custom ROMs.
Look up "Force LTE" in the Sprint forums. See if that changes anything. (You might have already done this, though)
EDIT: Dial *#*#4636#*#* and change it to LTE only and if that works, LTE + CDMA. If that works, try CDMA/EVDO/LTE (default).
BTW: Where is said tower in San Jose? I live there (here?) and I rarely get LTE signals (but I do).

Forcing LTE only didn't seem to help.
Here's my plan for tomorrow:
1. Drive to official LTE launch market
2. Test for LTE connection with phone as-is
3. If LTE=YES, happy camper
4. If LTE=NO, run the RUU to flash everything back stock (I know I shouldn't need this, but I'm grasping at straws here)
5. Test for LTE after RUU is complete.
6. If LTE=YES, happy camper
7. If LTE=NO, exchange for a black Sprint HTC ONE (Have Silver now). Maybe there's a bad few in a row.
I'll post tomorrow with results.

Also, to be clear, I'm NOT on a custom ROM. I'm on the Stock Sprint ROM, just unlocked and rooted.

I have had better luck with setting my network mode to automatic instead of cdma/lte ... I live In the Fremont area I see tons of areas light up with LTE now ..
But once I get to my house or my shop for work I have nothing lol.

There are a lot of people working really hard to get launched. Glad you're seeing some of that paying off.
I've been going into panic mode with my personal HTC One. I had a horrible experience directly with Samsung on my Galaxy SII. I was hoping to just pick this up and see the heavens open and the light shine down lol.
That hasn't been my experience thus far I'm jealous of all of you happy modders going crazy on this beautiful device. I hope to join you soon

Black HTC One all the way! With any luck you just got two lemons. That's pretty awful luck though, and kind of crazy. Maybe you need to sit on top of the tower.

>Getting my climbing gear out now< LOL
Black ONE is on the way.
Should I just leave the bootloader saying "Re-locked" or go through the dance to get it back to saying "locked?"
I sent the first dud back "Re-locked" as the guys in the store didn't seem to care at all. I guess it's probably no big deal.
I have done very minimal identical items to both phones:
1. Unlock via HTC /Fastboot
2. Install TWRP 2.5 into Recovery via Fastboot
3. Install SuperSU by following the prompts from TWRP 2.5
4. Installed the 3-button mod here: http://forum.xda-developers.com/showthread.php?t=2251788 via TWRP 2.5
5. Installed "Power Toggles" from the Google Play store. (After this step on each phone, Bluetooth would connect, but no audio. I also never saw LTE work again)
6. Reflashed the official RUU after things aren't working.
You guys are all pro modders, is there any step here that would stand out to you as potentially damaging to getting 4G LTE or maybe hurting the radio file somehow? I see everyone having a field day modding and flashing custom ROMs, now I'm scared to do even the basics for fear that somethings going on behind the scenes.
I've got to go do some actual work now. I'll post an update when the Black ONE comes in.

I have had the same problem of LTE not connecting anywhere. I have done the same things as you, including installing power toggles. If I remember correctly, I believe my LTE quit working after installing it as well. I find it hard to believe that the power toggles app could be the culprit, but it's a possibility I guess.

Hmm...weird. Before and after I rooted my phone and installed TWRP 2.5 with Super SU and left my phone "as-is" I fortunately have always had LTE in the downtown Hayward area.
I've been able to flash custom roms and not really have any issues other than those related to the Rom itself. Hopefully you really did just have bad luck...maybe buy a lottery ticket? Lol.
Good luck with your next One!
Hope it works out for you!

The only thing that doesn't sit right with me is that after I run the RUU to restore everything, you'd think the issue would be fixed right?

Well look at this everyone...does this sound familiar?

"UPDATE: awww, one of those 2g/3g toggle widgets permanetly turned off the LTE radio. Yesterday I could see LTE from Tmo, ATT, Cricket, and MetroPCS. Today all LTE options are gone. When I go into *#*#4636#*#* I can re-select LTE/GSM/WCDMA as a preferred network, but when manually searching for network the phone still can't see any LTE. Power cycling the phone, the field goes back to "GSM auto (PRL)", does anyone know how to make the preferred network stick with LTE without changing back in this hidden menu? What should be in this preferred network blank? and how do you make it stick? anyone?"

The only thing that doesn't sit right with me is that after I run the RUU to restore everything, you'd think the issue would be fixed right?

Yeah you would think so. I have ran the RUU on 2 seperate occasions just to make sure and still no LTE. I will probably just end up trying to exchange it for another one and hope the new one holds up better.

Now we just need one more brave soul to test power toggles to see if it really is a problem. If it is, contact the dev and tell 'em to declare it incompatible with this device!

I agree. If this app is causing this kind if an issue with the One, we need to verify and make sure that nobody else installs it. Maybe someone has a One that they are about to exchange for a different issue would be willing to test this theory for us.

I don't know about the 2G/3G facet of it (simply because it's never been noted as compatible with my device in Power Toggles), but I've used this app for a long time and I pull LTE quite comfortably.

Update: called Sprint about the issue and they notified my local Sprint store that when I brought my phone in, they were to exchange it for a new One (not refurbished) at no cost. They were out of stock and I should be receiveing it Saturday or Monday
