[Q] Android 2.2, no 850MHz 3G band available on X8 E15a - XPERIA X8 General

Hi Everyone,
I'm a first time poster here, so please be patient with me.
Just today I installed this ROM onto my Xperia X8 E15a:
MiniCM6-1.0.0 *Released*, Froyo Cyanogen 6.1.3 port for the X8
It works nicely and is a great, except that I can't connect to my mobile phone carrier. I am 99% certain the problem is that my carrier operates on the 850MHz frequency, and I'm guessing that the ROM I installed is supporting the E15i's supported frequencies of 900 and 2100MHz.
My phone can scan for networks and it picks up carriers that use 2100MHz, but doesn't find my carrier, who uses 850MHz.
How can I force the X8 to connect at 850MHz? I know if this can be done it will fix my problem.
Thanks to anyone who tries to help.
JC.

Update Xperia X8 with official firmwares or custom firmwares
Official versions of E15i/E15a listed in this thread. Download the appropriate version and use Flashtool.

Thanks bailey_ca, love your work!
Before I encountered the above problem I bricked my phone while attempting to upgrade to Android 2.2. To get the phone to work I used FlashTools to put a 2.1 rom back onto it, but I mistakenly put on a E15i European rom instead of the US one.
The European rom is designed only to work with 900/2100MHz 3g bands, whereas I needed 850/1900/2100MHz bands, like my phone is designed to use.
I flashed back to the 2.1 rom designed for the E15a model, then up to Android 2.2, and it all works great, 3g and all.

how can i know the bands my phone is using?
I'm having a similar problem.

[CONFIRMED] --> *** X10A users: Android 2.1 Update works for X10a ***

We are all waiting for our country/operator specific update now that the Android 2.1 update has been officialy released for Nordic countries.
The aim of this thread is to exchange experiences and share news
for those of us who got the X10a hardware version
(850/1900MHz bands for some Australia, North America and Latin America operators)
If somebody with an X10a has already updated, please share if you got it straight from SEUS/PC Companion or by changing to a Nordic 1.6 first, and then updated to Nordic Android 2.1
A "Yes I just got 2.1" is now what we expect:
Please share as much info as possible
(method used to update, tested radio 3G connectivity, locale, operator/carrier, language, etc)
Let the fun begin
[EDIT NOV 04, 2010]
NAM 3G bands: CONFIRMED WORKING
Overwhelming feedback confirms both currently released Android 2.1 firmwares (Nordic and Global) DO WORK for the X10a.
jerpelea suggests Sony Ericcson may have unified the bands because the X10i firmware works on the X10a, 3G and all.
ENGLISH, SPANISH, PORTUGUES languages: CONFIRMED PRESENT
Source: http://forum.xda-developers.com/showthread.php?t=824935
Released firmwares tested to date by xda-devs users:
- Nordic region Android 2.1 --> reported OK from many X10a users
- Global international Andoird 2.1 --> reported OK from many X10a users
- Notice: some users (espcially Rogers Canada) are reporting problems with 3G speeds (check next pages of this thread)
Where to obtain instructions and the Android 2.1 update firmware:
- 2.1 firmware "Nordic" and flasher by Bin4ry: (this is the one I used, a nice tutorial by user gfgodoy at post 3): http://forum.xda-developers.com/showthread.php?t=825201
- 2.1 firmware "Global" and flasher by jerpelea: http://forum.xda-developers.com/showthread.php?t=683793
- 2.1 firmware "Gobal" and flasher by MarylandCookie: http://forum.xda-developers.com/showthread.php?t=825675
TIPS:
- Charge your phone, at least 50% prior to updating the firmware
- Extract the flashing tool into a folder in your root directory ("C:\")
- Make sure you put the firmware files into it ("C:\X10Flash-2.1\firmware")
- Make sure you have "SEUS" or "PC Companion" installed and you have connected your phone at least once (for it to install the USB drivers)
- For problems ("unable to open channel", "Exception in *** java", etc) plase check this nice thread by Bin4ry: http://forum.xda-developers.com/showthread.php?t=823115

2.1 for x10a can be found in Dev thread. I'd do it but at work blah. Another 9 hours till home
Well, I will wait until TELCEL or Sony Ericsson México says something about the date of the release of the 2.1 update, if they don't say nothing or the date is about a month or later, I will use other methods...
could you please link ??
I can't seem to find a successful attempt
and all of our efforts are fragmentated into many threads
I just installed the X10i 2.1 on my x10a and rooted. It works fine except it occasionally loses 3g connectivity and steps down to the 'H' (I don't know what H means). But even in 'H' data works.
The big difference I noticed was the different apps loaded faster. But overall the system is still sluggish and bringing up the app menu is choppier than before. All the Sony stuff like Dialer, Mediscape, timescape are still choppy.
So I guess you will expect this on the x10a roms too.

Yep it worked flawlessly. The Market that shows up for me is the Canadian one and it even gave me the option to run using English (Canada). So I guess that stuff does not depend on the rom.
You just have to make sure everything you need to flash is installed and running. Most people have problems with java but there is a link in there that tells you how to fix it.
Then I used this to root. http://forum.xda-developers.com/showthread.php?t=824788
Information for default.prop & build.prop
I remember seeing information about changing the Build descriptors on both of theses files - Where you cahnge the values:

Mine is running Generic LAM - 1227-4607
What is the build.prop number for Generic North America - Generic NAM???
Thanks for sharing experiences
Will go for it myself and update the front post when double-checked
I'm interested in how it works as well. I own an X10a, but I live in Europe, so I'm wondering if it would matter anyway. The smartest move would probably be to wait, but if it's going to be a matter of weeks instead of days, I may jump on the X10i update methods.
I have debranded X10a and rooted 1.6. I read your tutorial on forum. Just a question is this for X10a? Would my phone change to X10a or x10i? Is there any chance to brick the phone? Does it removes all the apps? And my root? Please let me know thanks

It works great for my X10a from Brazil.
Thanks everyone that made this possible.
Can't wait to give it a shot. Off work in 4 and a half hours and it could come soon enough!! LOL
Does this firmware includes SPANISH language????
Just want to mention that I too have updated my X10a using the methods described above (just follow the directions in post #3 of the 2.1 flashing thread).
I have tested, and root worked (have already restored many of my apps via Titanium and am posting this on my laptop tethered via Barnacle). Market works too, and appears to be displaying the Canadian market for me properly.
Thanks for the info everyone.

ATTN: AUSTRALIANS who upraded to Froyo 2.2 via Kies using NZ/Telecome i9000T update

I have done this, moving from the JH3 firmware 2.1 Eclair to 2.2 Froyo after usign Kies registry patch and spoofing Kies into allowing me to upgrade to the recently released Froyo 2.2 update for i9000T phones (ENGLISH) that require full use on the 850MHz band.
I have done the upgrade successfully and wow - absolutely astonished that the now TELECOM branded firmware which *ALSO* utilises the same 850MHz handwith as we do here in Australia via Tesltra - I DO NOT HAVE ANY NETWORK DATA CONNECTION. The only way I can is if i connect to my home wifi.
I now beg someone, preferably an Aussie or Kiwi whi has actually DONE the flash and very clearly explain, in full - either what i have done wrong or how this can be fixed.
Thanks
RoOSTA
--------------------
Side note: 2-3 months ago Telstra AU should've already given their customer base the option to upgrade to Froyo 2.2 and the time its taken (Optus AU first, then NZ Telecom), is beyond ridiculous. I have a separate problem which has caused me to update early due to some bullsh*t link that Andriod market needs to have constantly with G_TALK:
http://forum.xda-developers.com/showthread.php?t=851043&page=5
Hey man.
I don't have a Telecom Galaxy, but have you done your APN settings etc? Telstra's APN settings should be publicly available, or give Telstra a call and ask them.
It is one thing having your firmware sorted, but if you have no or wrong APN settings, you wont connect to the net. Good luck. :>
Id be inclined to think its apn settings. Just install csc to match your provider.
APN settings not activated properly. Thanks.
Any Telstra users here have the link it takes you to when you open/click "Telstra MyAccount" ?
Thanks
Just install Australia Unbranded I9000DTJP5/I9000XSAJP4/I9000DTJP3/I9000DTJP5 it has all APN settings for the required AUS networks.
he needed 850MHz band.
Did you try this?

So after the APN settings were used, was this then fixed?

Wildfire Radio Change

hi all,
already searched but could not find a definitive answer.
basically, i have a htc wildfire a3335 (850mhz version) and accidentally flashed to an a3333 froyo (2.2.1) rom, losing the 850mhz (my carriers primary network).
obviously i need to change the radio, but have had no success so need some help.
either
1)revert radio to telstra
2)downgrade and reflash with stock 2.1 telstra rom
3)somehow force the new OTA froyo update
i currently have a generic htc rom, but i don't use the phone much, so the stock locked rom will work fine for my purposes (don't need to root or anything, just make calls).
if anyone can help and is in the local area (melbourne, australia) i will pay well for their time.
thansk in advance,
josh

If you don't have a custom recovery installed your gonna have to wait for alpharev, or search for the telstra froyo ruu on shipped-roms.com (which I don't think exists).
If you do have one like CWM or AmonRa, you can check this tread, I think that there's a link for the "flashable" telstra radio so you don't go back to a branded version...

thanks for that
i gave the noobs guide to downgrading another shot, seems to be downgrading now. its a tricky guide, not really for noobs, but my basic computer knowledge was enough to work it out. took about 45 minutes, mainly me being scared and paranoid
will post after the telstra ruu completes, then see if i can get the froyo OTA update (which i should have just been patient for in the first place )
phew! all done.
thanks very much for the downgrade guide, was a bit scary and needed a lot of concentration, but worked without a hitch.
long story short, if you want your telstra phone updated, be patient!
I have a Telstra phone that I upgraded to a stock WWE 1.37 ROM.
It works fine on the Telstra 3G network at high speed.
The frequency it operates on is dictated by the hardware, not the firmware.
However if you swap provider to say Optus, then it will switch to 2G operation as the Telstra phone hardware works at 850 Mhz (and others) while Optus netwrok runs at 900Mhz for 3G operation. Therefore the phone will drop back to the 2G frequencies and network and therefore run slower.
Go to shipped roms and select an HTC WWE rom (but not Froyo) and you will run at full speed. Likewise the custom ROMS will be fine also.

i dont think this is correct, 900mhz is optus's copy of telstra's country nextG network, called 'yesG' and is only for rural/remote areas
in most places optus etc run 3g on 2100mhz
i have a testra wildfire unlocked running virgin (optus network) 3g/hdspa fine, and i use a virgin dongle with an parabolic external antenna that only works on 2100
since unlocking ive flashed CM7 and a diff radio to get gps working, but i havnt tested to see if i lost 850 support. i will want this back though (if gone) at some stage so will be looking into this more.

I don't think flashing the radio to 3.35.20.10 makes any difference to Telstra's 850 availability.
I am fairly sure that Carnarvon only has the 850 frequency, and I am still getting a 3G indication and 2.5 Mbps download speeds (which is about normal), so I think we are safe!
Cheers
John in Sunny Carnarvon - Western Australia
Flashing a newer version of the radio won't make you lose 850MHz support.
I'm running 13.55.55.24H_3.35.20.10 and when i moved back to NZ i first tried to use 2degrees as my network provider, but they run on mainly 900MHz and I couldnt get reliable reception at home, but once i switched to Telecoms XT network which is a perfect frequency match for the A3335 Wildfire (the 850/1900 from Telstra) I've had no problems with reception.
If you really want I can upload the original firmware from the Telstra rom as a flashable zip.
no problems, i will wait till i can test if it still works on 850 and was also wondering if flashing the radio that came with telstra could help get bluetooth working with CM7, but is prob more an issue with CM7

[Q] Help - can't get service using Brazilian SBF

Hi Everyone,
I recently flashed the Brazilian MS2 SBF (was using Australian Vodafone ROM) in an attempt to get 3G working here in Canada (Rogers; 850/1900).
When I flashed the Brazilian SBF, I was able to get a connection very briefly before getting an error that my SIM is not authorized for this network.
Does the Brazilian ROM institute some sort of SIM-lock? If so, has anyone got around it? I haven't had any problems with UK, Australia or original Chinese ROM (phone eBay'd from HK)
Is it confirmed that the MS2 can in fact properly baseband switch from 900/2100 to 850/1900?
Thank you for your time and help!

u should find ur answer here:

I had a look at that thread earlier.. but no avail. Actually it turns out they released several Milestone 2s, and not all of them are tri-band 3G. Some are dual - this is the risk of getting these phones early off of eBay. Mine is 900/2100 3G - I need 850/1900 3G. Stuck with ****ty EDGE until either 1) I move to a new country 2) my phone carrier changes infrastructure - both not happening soon.

[Q] Defy with 850/1900 3g bands

Hi, terribly sorry if this is a repost but I've searched all over general and don't see an answer.
I've seen posts on other sites that state the t-mobile defy can be used for att 3g but will not have the 1900 band, is this true?
In that same thread I saw someone claiming that you can get both. On gsm arena I see that some defy's should have 850/1900.
What version supports both the 850/1900 bands for 3g?
Thank you,
I've brought this up in another thread and there was no reply. From what I read there is two issues here. First is the hardware and then the ROM you flash your defy with (firmware). They both need to support the frequency. I suspect the hardware is the key.
So if your phone hardware does not support a frequency I don't think you can switch it by any firmware. (This is all about 3G by the way, Defy is quad-band for 2G, GPRS, and supports all 2G frequencies.). I think Defy UK is 900/2100 for 3G on T-Mobile.
This could be wrong so I hope some expert will reply to confirm it - and perhaps tell us how we can check what frequency our Defy hardware/firmware supports!?
Could you try to read this forum
http://forums.whirlpool.net.au/archive/1598301
Thanks for the reply, it's a long thread on that forum and talks about just about anything (not specific to Defy + 3G). But I had read it before and had another quick look at it again today.
One thing I couldn't find was how to check what 3G frequencies your Defy has Firmware/Hardware. Anyone ?
XT535 no 3G (WCDMA 1900)
I recently bought the Defy XT535, and I didn´t take note on what frequencies did it worked on.
I have read on the thread dedicated to update the XT535 from GB to ICS that some people have problems with their 3G connection working after the update, and I think it has to do with the chinese SBF file.
I´ve also read in http://forum.xda-developers.com/showthread.php?p=11176044 you can fix your 3G connection by flashing a new SBF file.
Unfortunately, I haven´t found a SBF file that can be flashed for my device that will fix my 3G. Anyone has solved this issue already and can give me a hand?
XT535 HW didn't support WCDMA 1900. http://www.gsmarena.com/motorola_defy_xt535-4622.php
Changing baseband won't help.
Furthermore, that's thread was so old. They use "zip" patch to fix baseband, not .sbf (.sbf means to be only stock rom files.)
We now use Basebandswitcher to fix MB525-526 baseband easily.
