[Q]
Alright guys I need some help.
I have a Huawei Ascend G300.
Model Number: U8815
Android: 2.3.6
Baseband Version: 109808
Build Number: B895
Not rooted.
The phone specifications say that it supports 3G 850MHz,
but I get almost no signal using a 850MHz network.
I believe it is some sort of restriction placed by firmware maybe.
Might need custom rom or something so I can actually use the phone.
Any one can give me any information regarding this?
Thanks in advance.
What I should say is that it only works where there is 2100MHz reception (very few areas)
but I want to be able to connect to the 850MHz band that is available everywhere.
That involves the radio part of the firmware,which 99% people don't change.It's better off if you don't change it too.It's highly unlikely that they would wantedly block the reception of the phone,and its even more unlikely you'd have someone who has created a custom stable radio for a Huawei.Have you considered that the 850Mhz signal might be weak in your area,or that your phone's hardware might not be good at receiving it?If you're sure it's not either of these issues,your best bet is to restore it to factory defaults,or reflash the original ROM.

The phone has the original rom and is not rooted.

The phone specifications say that it supports both 850 and 900 bands.
I live in New Zealand where Vodafone operates on the 900MHz range.
The alternative provider Telecom operates on the 850MHz range and has full coverage throughout the country.
Given the specifications of the phone I can only conclude that either the firmware restricts use of a non Vodafone band
or that the phone is locked to Vodafone (however im pretty sure the phone is not network locked)
If anyone has this phone and is using a 850MHz network, I would like to know what firmware etc. they are running.
Thanks again for the help.

I've been reading around and I'm still quite confused.
I want to flash my touch pro with some ROM to enable the 850mhz band but I have no idea which rom to flash and no idea if it is the radio i need to flash or not.
Also what poses a problem is I'll lose all my custom settings and tweaks and everything and it'd be nice to know if I back the entire system up (and with what, i do not know) I can just restore everything and continue on my way using the proper band for my provider (900mhz is being used right now and my reception kinda sucks in buildings and whatnot)
Can somebody please guide me on what ROM/Radio I should flash and how I can back up EVERYTHING? (registry etc)
I'm actually going to modify my original question a little. After reading through some stuff it appears that the 1.02.25.28 sounds best and I'd like to flash it, but will this enable the 850mhz band or is a ROM flash also required for that?
Secondly if I just upgrade the radio, will that require a hard reset?
there is no 3G 850 band on the touch pro. theres people working on it, but it looks less and less likely that the hardware is there. if you need the 850 mhz 3G band buy an at&t fuze

I'm not talking about 3g I think. Just GSM/EDGE
Hello!
I would like to ask if the XT720 could be set to work in HSDPA 850 band for 3G service.
In my country, I have a standard gsm service with edge slow speed internet service,but for get 3G connection is needed that the phone works with HSDPA 850.
So, after reading some links, I wonder if the XT720 could be switched from HSDPA 900 to HSDPA 850 via an update/patch/internal set to the baseband software that make the internal radio section hardware set to HSDPA 850 or if the access for use HSDPA 850 may be due with a radio hardware circuit board specifically made for HSDPA 850 and then the board in the XT720 is specifically made HSDPA 900.
Thanks for any info/help.
best regards to all.
It is very dangerous to mess around with basebands many have brickt heir phones doing this.
Sent from my XT720 using XDA Premium App
Thanks for take time to reply... and I agree with You... I was checking info about the specs of the XT711 and I may believe that is probably that is the same hardware that the XT720... so I wonder if may be possible that a version of basebandswitcher may be possible too for our XT720 phones...
Of course that after follow the post about the bricked phones, the current version of basebandswitcher V4 is clearly for Motorola Defy and is bad medicine over an XT720, but seems like that Moto softs are similar, and the dirs structure may make possible to suspect that basebandswitcher may be adapted, only finding the proper registers for XT720, and by the way fixing the phones of the friends that take the challenge to test in their phones... sadly, thsi is very far from my knowledge.
By now I copy the full contents of the dir:
/system/etc/motorola/bp_nvm_default
as the developer of basebandswitcher suggest and try to inspect them, but all the info seems as binaries.
Well, hope that a fix for the baseband bricked phones could be found since it may also show the clue for make a basebandswitcher version for XT720 that could be an awesome feature.
Thanks again and best regards
Hi all
I just got this phone for use in Italy, and am now waiting for my unlock code to come through.
Meanwhile, and as the main question, I wonder if it ever will be a way to turn on the WCDMA 900 band that we use here (along with WCDMA 2100), since it's not supported out of the box, being an American phone.
I would like it to be a 900/2100 phone, instead of 850/1900/2100.
I'm sure the phone supports it (being much newer than my current Motorola Defy that's able to do it), it just has to be unlocked somewhere.
Any info is appreciated!
Thank you

Sorry, but that is not possible as the hardware does not have those radio antennas in the phone. This is ONLY a GSM/HSDPA+ phone not a WCDMA phone. There is not a way to change that since it is a hardware antenna change.

As far as i know (pretty sure on this), all 3/3.5G is WCDMA. HSDPA(+) is WCDMA. WCDMA is just the name of a RF modulation, and 850, 900, 1900, 2100 are just the bands the protocol can run on.
In fact my question could just be translated to: as these settings are stored in the baseband rom, we need to flash an alternative baseband to enable those, or discover where they are set.
I guess a motorola phone similar enough to the A2 (i.e. same.hardware) should suffice as a "donor" phone for the baseband rom. May be an ipothetic european A2 of the future.
Has a phone like this been found yet?

The hardware on A2 does not support this, the antenna is not setup to capture these frequencies. Just because the baseband is in the rom does not mean that you can change the hardware.... Yes technically all 3G boils down to WCDMA or CDMA technology, but there are major operating differences between even the different spectrum in them. The issue you have is that the phone is not going to be able to capture those on the hardware layer. It is similar to trying to get am radio signals on an FM radio, with an FM antenna.
Well I hope you are wrong
I think (hope) motorola has put an universal antenna on the atrix 2, it'd be anti economic to do otherwise.
BTW, 850, 900 the antenna differences surely are minimal.
It sounds more like as a RF chipset limitation on the simultaneous bands used... like three of em. "Tri-band umts".
As with the good old gsm phones marketed as tri- or quad-band, like my v525, the actual bands used were depending on where you lived.
All of this, i hope...
Did you buy an MB865, or an ME865, as they have two totally different antennas. mostly we discuss the MB865 in here.... and I can tell you that there is no way to change the MB865, because it setup that way on purpose, and locked to AT&T's signals via the antenna and wireless chipset, by Motorola. The ME865 might be a better choice I think there are two versions of that one, one is the Chinese version and the other is more international.
ME865 it's for asia only. Motorola phones found over here follow the MB nomenclature. I have got an at&t MB865.
Anyway if a €300 phone (defy) can do that, I don't see why motorola would have chosen to spare on a $ .5 part on a €550 phone (euro price tag estimation), and have to redo a whole new pcb layout if the MB865 ever comes to the old world. Even taking into account the at&t exclusivity. It's anti economic for them.
Btw I don't want to be right at all cost, please don't misunderstand my words. ;-)
Also if you look at pdadb you will find two.models, mb865 and mb865a.
I don't know if they're both real or not, but they are identical specs-wise the only exception being the lack of wcdma900 band on the "a" version.
If such version actually comes to market, i guess a baseband transplantation could be done...
Cliffs Notes:
I need a phone that will operate unlocked on GSM 900 that I can also program to use MY (not the carrier's) WiMAX base station at 2.5Ghz. Recommendations?
The longer version
Title pretty much says it all.
I'm running a Lab network that does GSM/EDGE and I've also got a WiMAX base station at the 2500 band with my own CPE's.
I want to use the Sprint Motorola Photon to access all three technologies by unlocking it. The GSM/EDGE should be cake.. It's a world phone so I shouldn't (hopefully) have to dork with unlocking it OR I can set my lab system to mimic a Sprint MNC/MCC push come shove.
The WiMAX is a question mark. I know I can allow the phone access to the base station, but getting the phone so see the base station is the question.
I assume I will need to somehow tell the phone to stop looking for Sprint's WiMAX and look for my channels instead. Seems like it should be doable - it's all IEEE 802.16e. The biggest challenge I see is reprogramming the appropriate WiMAX channels into the phone assuming it doesn't scan the entire band automatically and attempt to authenticate whatever it sees (like the way GSM does).
Before I drop $700.00 on a pair of phones though, I want to know it can be done.
What say ye?
Edited to provide more background info: My lab network when running GSM runs in the 900 band. I'd read where people were using the KDDI radio (I assume from Japanese carrier AU KDDI?) to enable USA / GSM.
I get the impression that I wouldn't have to do this to operate the phone at 900MHz GSM (ETSI spec), but what about the carrier unlock? Would the phone care at this point and want to see a 'Sprint' signal or would it accept any SIM (to include a made-by-me GemAlto?)..
Still though.. Need to know about the WiMAX bit.
For that matter, what about the Galaxy SII ISW11SC version. My understanding was that AU KDDI operates it's carrier services using CDMA2000 @ 800MHz. But I have also seen published specs that this version of the GS2 supports GSM as well as WiMAX2500. Perhaps a better potential candidate?
no takers?

Hi Guys,
So I've been running Clean Rom for roughly 6 months now, still running version 5.1 (Android Version 4.0.4) on my HTC ONE XL.
My One XL is a Telstra branded phone and thus has the capability for 850MHz. I was running on the Vodafone network and therefore not using said band, however I have recently swapped over to Telstra (Was never with them in the first place).
Unfortunately I'm not seeing the gains in reception I was hoping for, and I am currently finding that when going to locations where there should be signal, albeit edge, crappy signal, I am receiving none. My question is, does Clean Rom disable the 850MHz frequency or does it still support it? Is there a way I can check whether I am accessing the 850MHz network, and if so, how? If it isn't am I able to turn on th 850MHz frequency?
Looking forward to getting this sorted. Cheers.
ROM shouldn't make much difference in band compatibility. Since your version supports 850 MHz for both 2G (EDGE) and 3G, it should work regardless of ROM, and you don't need to "turn it on". There are "secret codes" you can enter into the dialer that will tell you information about the bands, and also signal strength. Just use the XDA search function, and you should be able to find them.
You might see some slight improvement if you are not currently on a Jellybean radio, and flash one (if hboot 2.14 or higher, you will need to s-off). But I wouldn't bet on it making a huge difference.
What makes you think you should have (crappy) reception in the mentioned locations? From reception on another phone? Every phone is different (antenna design, etc.). Since you mentioned the reception at the location is already crappy, its probably more of a antenna issue than a ROM issue.

I'm not sure where you're located, Telstra is the largest Telco in Australia with the largest and best coverage. Vodafone unfortunately has a very bad reputation for reception. Swapping from Vodafone which does not use an 850MHz band to Telstra, which does, has netted me reverse effects. I am receiving worse reception, which should not be the case. If I go into fringe areas where edge is the best signal you receive, I will receive none, where as in town locations where more than the 850 band is used, I receive okay signal. Just seems like I'm not picking up the 850 band.
As I already mentioned, search for the "secret" dialer codes. There are codes that will tell you the cell tower signal, and I believe band, which sounds like what you need.
None of the dialer codes seem to allow me to see what particular frequency I'm using. Unless I'm just completely missing something? The only thing that seems to provide me with info on the radio only states Network Type and the DBM.
