[Q] How to Install CM 7.2(0.32) over 0.35 baseband

[nayneshdev]

Dear Friends

I know that if i want to go back to 0.32 based rom from official GB i have to first downgrade to Froyo. But my question is isn't there anyway by which we can directly flash Ezet's cm 7.2 without downgrading by modifying something may be? I am sorry, I am not a dev and don't know much about it, but the fact that i have to downgrade is kind of scary for me. There are a few more questoins;

How safe is downgrading to froyo?

What exactly is the (technical) reason why we have to downgrade (if at all) ?

My current setup is as following:

Rom: T.M.C. CM 7 (0.35)
Recovery: 5.5.0.4
Partition Scheme: Forumber's zip

I presume to downgrade I must do the following

1. Revert back to stock partition
2. Flash official froyo in pink screen mode by copying dload in internal as well as external sd card

Is this correct procedure?

Besides this i have my pink screen dump of stock froyo using dd on linux. Do you think restoring this backup is more safe in comparison to installing through pink screen?


Reasons why I want to downgrade : TS lag, Poor GPS in every 0.35 or 3.0.8 roms, poor battery backup.

Thanks for reading

Will this work?

Well the objective is to flash froyo baseband rom (e.g. Ezet's CM7.2) directly from gb baseband (404020) rom without having to install official froyo.

For now i know that the kernel and the baseband is different and from what i have read at droidforums.net

"The baseband is the subsystem of the phone that controls radio communications. It's a chipset on the phone that directly controls cellular hardware and communications with cell towers." (Enlighten me if this is wrong?)

Now i have the backup of my imei in 5iromtoolbox when i was on froyo. Does that also backup the baseband? If it does then

(1) We can reflash the froyo baseband on gb/ics(404020) using 5iromtoolbox, then
(2) replace recovery to 5.0.2.7
....????? (anything else required)

(?) flash cm 7.2 from Ezet?

Now the question is Will this work ? If so what will be exact steps
