Flashing 2.2 Froyo to US T-mobile phone?

I was reading the thread about the hack to be able to flash a ROM from another region onto your phone by changing some system registry values. Is it possible to use the Froyo 2.2 ROM from another region and the modem firmware from the released US 2.1 firmware package in order to flash a US T-mobile Vibrant phone and still have it function on the network, but be running the 2.2 OS? Would this work?
I believe that this version of 2.2 is only for the i9000 version of the galaxy s; the t-mobile version is T959.

Huawei H883g Mistake

Hi, I own a Refurbished Huawei H883g. I know that this phone came stock with the Portico 8.0.10211.204 which does not allow you to upgrade to the Windows Phone 8.1 OS. In order to get to that OS I flashed the GDR1 update to the phone, then updated to GDR3. As it is my phone has the following settings:
Name: Windows Phone
Model: HUAWEI W1-U00
Software: Windows Phone 8.0
OS Version: 8.0.10521.155
Firmware Revision Number:
1030.5614.01000.20900
Hardware Revision Number: HD1U8835M Ver. B
Chip SOC Version: 8230
Now that I flashed the phone though, I did more research after some trouble and found out that due to drivers I can't upgrade to Windows Phone 8.1 after all. Not only that, but now that I have flashed the phone I can't get 4G service and am stuck with EDGE. Now I just want to flash the stock ROM back on. My problems:
1. I'm a total amateur and barely got through the first flash.
2. I can't find the stock ROM.
3. I'm assuming I'm gonna need the original drivers as well.
4. I need the bootloader as well.
-OR-
If any one could tell me how to get 4G service back I can just stick with the OS I have and be happy.
Pleeeeeeeaaase help me!

XT1064 - how to reflash modem?

Hello.
Please help me solve the problem. I have XT1064, and 3G 1700 AWS do not work in my country. I want to try forcing the firmware from ХТ1063 by force, and everything even works out for me, except that in the settings - about phone, the modem version is always written old. On any firmware. Even with downgrade. How to flash a modem, and where can I get its files?
I tried a whole versions of modems (NON-HLOS.bin and fsg.mbn) from different firmwares - but the firmware of the communication module is always the same version of MSM8626BP_1032.3116.99.00R RETUSA_AWS_CUST. I need a RETGB modem from XT1063.
Sure, i know about flashing modem from another model - may hardbrick my phone, in emergency case i have a programmer box. But only for restore, not for flashing.

Uknown Baseband - Can't downgrade modem to repair IMEI

I'm using a Galaxy M20 (m205f). Trying to root it, I somehow messed up the radio and efs partitions. Tried to install the latest stock Rom and it updated the binary from U4 to U7 with a null IMEI and unknown baseband. The IMEI repair softwares need the modem and the modem version presently is of U7 binary which is pretty recent and no IMEI repair tool supports this modem version yet. Is there any way I can downgrade the modem? There's no lower Android version and no combination file for the U7 binary on the internet so I'm stuck. Can I somehow put an older CP/Modem (from lower binaries) and make it work with the latest firmware?
