I have seen many threads talking about basebands, but I can't find anyone clearly explaining in which country/region a given baseband in supposed to work well, and where it doesn't.
I need a Gingerbread baseband for my Optimus 3D that will fully work in Latin America region, I'm afraid to get in trouble if I flash the european GB baseband I found in this forum, and loose some (or all) frequencies in my country.
Thanks in advance!
Me too. I'm in Canada and when I flashed the euro gb baseband I lost all connectivity.

I know these boards have picked up a bit but it's kind of depressing considering all the action I see when I check up on the Sensation threads for my other phone. You'd think that because this phone is so sweet and comes completely unlocked there would be a lot of development going on.
Good Afternoon!
Just for fun I thought I would flash the recent GB KDZ file posted.
Still having the same issues registering on the network. :/

I flashed latest KDZ file for o3d even though i have a thrill 4g and 3g and all other things work great except i don't have 4g to test on this country

I have no idea why it's not working. Both AT&T and Bell use the 850 and 1900mhz frequencies for their respective UMTS networks, but up in Canada we can't even get the phone to recognize our network. I'd be happy with 3G speeds for now, but that's not even possible. I wonder if AT&T uses other bands for 3G speeds as well?
My phone is a P920 of European origin and have had to put the 3G baseband of a Thrill. This in Froyo. Also the one I have worked p920h.
Until no one KDZ for America or get a baseband for this continent, you lose the 3g frequencies 850 and 1900.
Keep in mind that the baseband is independent of the rom, which means that after installing the baseband you can put any rom, whether European or American.
The Ginger there so far is European and therefore everything is lost that frequency.
Sorry for my language.

Good Evening,
I wonder if a baseband from another Gingerbread device could be modified to work with the Optimus 3D. What about one from an Optimus 2X?
Just a thought...I wouldn't know where to begin!
just a quick question, my carrier works under 2100 Mhz I am located in Costa Rica, if I do put the euro version will the network not work....
---------- Post added at 08:28 PM ---------- Previous post was at 08:10 PM ----------
my question is since I do not live in Europe, what exactly euro open means
I'm using euro gb fw, and everything is working fine, although I have an edge icon instead of 3g, think it's cause of the region can't remember if it happened with my old x10.
this can be an issue unless it's showed like that when not having data enabled
edit:
I'm on a 3g network and I have edge enabled :S, we need LAM baseband Q_Q
I happen to be in a 1900 umts AT&T area, but it was too spotty and I went back to Froyo. Though for those of us who have to wait, I have a froyo custom kernel with init.d support below (thrillz) that I've been running on my p925 on the roadrunner rom.

Good Evening!
I figured I would install the GB KDZ again.
For no apparent reason after the reboot I was registered on the network (Bell) and have had no problems as of yet (Only has been an hour or so).
I wish I had an answer as to why it worked this time.
I will keep you posted!
Thanks, Audi.
yeah I'm in Canada too and eagerly await some usable Gingerbread with fully working baseband.
Apparently Rogers is one of the last carriers to get on board with Gingerbread and is holding up LG.
ARRHHG!

Good Morning,
My device is a Rogers device unlocked and used on the Bell network.
After flashing the V21a Gingerbread KDZ a second time I am having no issues at all!
I wish I could tell you why it worked this time when the original baseband flash method and my first flash of the V21a KDZ both resulted in network issues.
I didn't do anything differently the second time I flashed the KDZ and was immediately registered on the network. I have had no issues since lastnight.
I will let you know if anything changes!

Hi Audi.
Thanks for the info. I guess since you got on the bell network, the rogers network should also work? Maybe not actually because rogers GSM. Is your connection Gsm Too? I am a bit nervous flashing kdz file. Its not standard zip flash through cwm is it?
I also worried about flashing baseband.
Do you know if I have made nandrroid backup of my 2.2 and need to restore, will my backup flash 2.2 baseband back on automatically?
Thanks .
I use the same gsm network as at&t think it's the same as rogers, I randomly get dc from the network but comes back fast.
I think you should be aware that maybe your 3g network won't work using euro open fw
i'm always on edge :S

Hello!
When running speedtests I average between 2.5 and 5.5 Mbps (depending on the time of day). This is pretty much what I saw on Froyo. No complaints here!
Thanks, Audi.
Hi audi
How is your phone running lately? Any lockups, slowdowns, disconnects or anything? Full hardware working including wifi? Do you get 3g icon or edge?

Good Evening,
The phone is running great. I currently have the Acura ROM installed.
Battery life is an incredible improvement!
The icon I have is "H" (so 3G not HSPA+ yet); and the speeds are as previously mentioned averaging between 2.5 Mbps and 5.5 Mbps depending on the time of day and signal strength.
No random disconnects; voice and data (3G/WIFI) work without issue.
Thanks, Audi.
Hi, I recently bought a used i9103 on eBay that was imported from an overseas country (Still not sure which country), seeing as it was never sold in the US. After using it a few weeks, I notice that the signal jumps radically, even when the phone is stationary.
So my question is, which baseband/modem/radio would be best? (Specifically for T-Mobile USA)
As a note, I am in a major metro zone and other phones in this same area get a strong and consistent signal.
The baseband is currently XXLQ3.
Thanks.
You can try DDLP3 baseband from Indian ICS XWLP8 rom. That's the latest and that's why it should be the best one.
I flashed the modem alone from XWLP8. I'll report back in a few days if there's any difference. I guess I should also ask if there's any difference in hardware in the models shipped to different regions? Or is there only one model, just with different software?
There is only one model as far as we know, at least there weren't any others reported.
Just an update, flashing the Indian radio didn't seem to help at all. Signal still jumps up and down wildly. Turning on Data Roaming did not help either.
SO I just got one one yesterday. plugged in my sim, but noticed signal to be always bad. coming from my nexus 4, i can never get full bars this is even data, just calls and text service. Anyone think its a modem issue? I am on 33r btw, any help would be greatly appreciated.

There are some that are having problems with reception depending on where you live. Maybe look into flashing another mode ? Try digging around ( use Google : site forum.xda-developers.com oneplus one modem or bad reception )
Hi there.
I have just got a used-N5 on the Internet. It is a D821 (for Indonesia market I think).
Everything is fine except the LTE connection. (2G and 3G connection is normal)
The LTE problem is:
The searching speed is slow.
Even if LTE is connected, the response time and connection speed is extremely slow.
I have taken out my SIM card, and insert it into another N5 (D821) right next to this phone.
The speed is 10 times faster.
I am using CSL in Hong Kong, which the LTE is band 3 and 7 (1800 / 2600).
Baseband is updated to the latest version.
APN setting is correct.
No matter which ROM and kernel I use, the LTE problem exists.
Anyone have idea how to fix it?
Thank you very much!

Questions belong in Q&A.
Every D821 is the same, every D820 is the same. There are no specific regional versions for a D821.
The ROM and kernel have nothing to do with your network connectivity.
Try flashing a different radio version.

Excuse me, do you mean try flashing a different baseband version?
I have tried the one comes with Kitkat (4.4.4) but no luck.
I know every D821 should be the same, but I just wonder why under same configuration (ROM, kernel, baseband), but the result is different.
I suspect if my D821 is a remarked D820.
Thanks.

Yeah, radio and baseband are the very same.
With the exact same software, the result can be different because not every device is made the same; the perfect Nexus 5 does not exist.
The only difference between a D821 and a D820 are the LTE bands it can access, everything else including the 2G/3G bands are the same. If it was actually a D820, you'd probably get no LTE at all, unless your carrier supports one of the bands a D820 can access; it would not mean you get "slower" or "worse" LTE performance - you'd either get it or you wouldn't.
It might just be a hardware issue if you think it's slow.

I believe it is a hardware issue as well
If someone on xda give me a hope then I don't need to bargain with the shop
Thanks :good:
Hi all.
Last night I have brought it to the shop and tested there.
The LTE speed is very normal... I cannot trigger the problem by any means...
I suppose it to be the signal reception issue.
I left the shop and found the speed might be somehow dropped, but it could be still considered as normal.
I went home, re-flash another ROM and prepare for normal use.
However, the LTE becomes abnormal again...
I have found an interesting thing.
I have flashed stock ROM and OEM LOCK before bringing back to the shop, and it is normal speed.
I went home, OEM UNLOCK and flashed a custom ROM, it is abnormal.
Now, I have just re-flash the STOCK, and the LTE is not so normal.
But after OEM LOCK, it seems to be fine.
I believe there is no relation, but is it possible the OEM LOCK to do with the LTE issue?
Thanks. :crying:

Bootloader lock/unlock state has absolutely nothing to do with your issue.
The ONLY difference between having it locked/unlocked is so you can flash images. It does NOT affect anything else.
I am a web programmer. I always suspect something strange when something cannot be explained (bugs in coding, I mean)
I have tested several times today. Locked bootloader still gives a poor LTE result.
I really have no idea why there is LTE problem...

Again, bootloader state affects nothing but the ability to flash images.
Yes I understand.
Just trying everything to find out a reason...
Strange problem. I tried researching this problem and found nothing.
My OPO works just fine at everywhere except home and another location a few miles away from my home. At these places I can't make or receive phone calls. Data works fine. I flashed the newest resurrection remix, with full wipe. I also tried flashing 3 different modems.
I called T-Mobile and presented them with the problem and they said my phone many be too old and possibly not support T-Mobiles' new LTE bands. So, I asked what band am I receiving at home and they Dont know... I dropped down to prefer 3g and still no luck.
Anyone with a similar experience or may know what I'm dealing with please help. I still love my OPO and would prefer to not buy a new phone.

You might not be able to use Lte perfectly on T-mobile(as they already said) since it uses LTE band 12 mostly which OPO doesn't supports..though I guess 3G should work fine.
Also,I guess T-Mobile uses VoLTE to place calls,which again,OPO doesn't support.
Can you list out the modems/firmwares which you've tried so far?
4.0.1.c7-0013.zip
4.0.1.c7-0011.zip
DI.3.0.c6-00241.zip
Thanks for the info. I guess its time to buy another phone.

Can't you just change your Carrier instead?
LTE discovery app shows i am connected to LTE Band 4. 3 of 4 signal bars. Is it possible that t-mobile uses band 4 for data and band 12 for voice?

I am in USA. The next biggest carrier is Verizon which dont work on OPO. Metro PCS is the same as tmobile. I am not going ATT. OPO dont work on Sprint either.
