[Solved] iOcean X7 HD baseband testing

[aus9]

yeah well the only explanation I have is as follows

My network for 3g should NOT support band 900
3G test of 900 with 3G only is as expected a fail

That is already written in post 7
so the GSM with 900 setting appears to be breaking my WCDMA setting?

I don't care where the settings lie, per se, just looking for an explanation of what is happening.

thanks for your time

My previous post was an attempt to answer your previous question:

The image of that setting is bottom image in post 3.

Is this a fallback to GSM mode breaking the WCDMA only mode?

At this point I'm unsure of what you're asking or looking for an explanation for. If it's:

so the GSM with 900 setting appears to be breaking my WCDMA setting?

Then the answer is no. Nearly all phones have 4-band GSM on and engaged if you have SIM set to dual-mode (WCDMA/GSM) then depending on what carrier you're with or the strength of the respective signals, the phone may use one or the other.

I really don't recommend messing around with different basebands. As you can see in posts around the forum, it has gotten people nowhere and usually causes more troubles if anything. Just stick with the baseband and modem files you have on your stock ROM.

hmm

lets try again

we are in the 3G area
the setting mentions GSM or 2g
why?

I am suggesting that maybe this setting is breaking my WCDMA only setting?

Lets not continue if I am not clearer

thanks for reading

Can you show a screenshot of what you mean regarding "3G area 2G or GSM setting"?

I added 2000 back in before taking this shot, I can assure you it was only the GSM during the test

Okay. I understand now. That is the name of UMTS 900 on most MTK phones. It's the same on mine as well. Where it originated from and why they didn't give it a different name to reduce confusion is unknown. There was a time when 900 GSM was refarmed to UMTS and maybe that has something to do with it.

The iOcean X7 HD is 900/2100 UMTS. You won't be able to change that via software. At least, if you are able to, you'd be the first person I've heard of to be able to do it.

thats great relief I will close this now thanks

edit

they should not allow wrong settings to be in bold then
grrrr

this might relate to MTK engineering app ....not sure

Yes, its quite strange to see all of them selectable with the stock ROM. Jiayu phones back in the day were similar. Just some lazy baseband programming.
