MTK-tools configured in single band EGSM900 and running.

Anyone know what CMW is loaded in version 1.0.6??

regards

can you explain me better what this means ?
are you talking about an 850 phone with a 900 firmware ?

There are a couple of threads dedicated to this and a lot of users tried it, but no success.
It looks like it is hardware related issue.

offtop, but the new 1.0.6wcdma900 ROM made a 2100/900 phone from my 850/2000 phone. That healed the "3G/call ended" bug and others confirmed that it works on real 900MHz network too. So, it is not hardwer releated issue.

Just showing 900 in Engineering mode means nothing. This baseband/ROM swap has been extensively tested by @burs .

We would love to see proof of the actual working 900. If you have turned your 850/2100 phone into a 900/2100 phone, please provide the proof. That can be done by providing a high-res video with no cuts showing the turning off / deselecting of 2100 in MTK engineering mode. Rebooting the phone and showing only 900 WCDMA in engineering mode checked, then connecting to the net and showing H+/H.

Until this can be shown, it remains just a rumor.

In my country only Vodafone uses 900MHz for 3G but I have not Voda SIM. On of our local forum member has Voda SIM and he tested:
- Voda uses 2100 in the urban area and 900 in the countryside
- He used 850 type phone and when left the urban area the 3G gone
- He flashed over with the 1.0.6wcdma900 version (he uploaded that to needrom)
- He did the same trip and the Voda SIM had 3G in the countryside area with the new rom

Plus:
- We encounter the 3G=cannot call bug with Telenor SIM, who is uses only 2100 (theoreticaly) and after the 1.0.6wcdma900 upgrade this bug is swept away.
- I think maybe Telenor uses 2100 for 3G data and 900 for call in case of active data connection... I dont know, just thinking on ...

Anyway, I do not need to give a proof to anybody. You can download the 1.0.6wcdma900 from needrom, fell free to flash it and test it, it costs nothing. You need the proof do it for yourselfSmiling
I do apologize profusely if I came off initially as rude.

It's actually quite exciting news if it turns out true, and just would like to see some proof of it. All we have now is a guy who knows a guy who says he gets 3G in the countryside where he couldn't get it before. This is far from showing that someone has made their 850/2100 phone into 900/2100.

You don't need to give proof. That's your choice. If I was in Europe and owned an iNew V3, I would. If not just to benefit the community.

If you or he is interested in showing the forum your result, we would love to see it.

This isn't to be rude, but it's a substantial claim and has been tried by hundreds before you without success. So would be great to see this in the works.
a video would be great. This still would not prove it to 100%. The radios are hard tuned at the factory. Its like trying to use an FM receiver to listen to AM. Thats not possible.

The phones could have been 900/2100 from the start and have initially had incorrect ROM on them from seller. I'm not saying thats what happened. Its very unlikely. I just say the suggestion.

Do not take offense. Well a video would be a good start.
can anyone upload a separate file modem (modem_1_wg_n.img) from version 1.0.6 ?

The hardware same. I use my 850/2100Mhz with 900/2100MHz firmware and it's work fine.

The firmware works fine, but until someone shows their 850/2100 phone working with H/H+ on 900, being able to switch 850 to 900 remains a rumor.
