[Q] Please Help! Using 9020a on T-mobile.

I was currently using MIUI GB build from brainmaster, and I wanted to switch to the ICS after finally finding out they halted the OTA update. Well I'm using T-Mobile, and when i flashed the stock rom back, i was not able to us the 9023t stock rom as it kept giving errors. So i had to tried the 9020a (which i believe is for ATT) and that worked. My phone is able to make calls and receive texts, but it only shows that its on edge (e) and no more 3g on the status bar.
My question is, is there a way to switch the baseband back to a 9023t build? or did i always have an ATT branded phone?
edit:
This is what my phone status shows:
Carrier: Tmobile
Android Version: 2.3.6
Baseband: I9020AUCKF1
Kernal: 2.6.35.7-gf5f63ef

Build: GRK39F
Another update:
Just verified after pulling my battery the model states:
GT-I9020T

It seems that you have flashed an I9020A baseband on an I9020T. There have been reports that people who have done this have never been able to get 3G again.
However, you can try to follow this link and flash the KI1 baseband and see what happens.
Just out of interest... do you know anyone with an AT&T sim that you can borrow to see if you can pick up AT&T's 3G now? (you would have to make sure that then APN for att is entered and selected) It's extremely doubtful but would be interesting to know nevertheless...

I will try and flash that baseband, and will update asap. As of right now, I dont have an ATT sim card, but if i do come across one i will update as well.

Also, do you know why it happened to let me install the 9020a rom, and not the 9020t? I had to root my phone from scratch all over again to erase the MIUI rom and to try to bring it back to stock. Every time i tried to install the 9020t/9023 it kept giving me the error message:
E: Failed to verify whole-file signature
But it worked like a charm when i attempted to do it with the 9020a.

I was able to flash the KI1 baseband with no problems at all. Now with this will I be able to flash ICS?

Either flash the official OTA or an ICS ROM that doesn't contain a radio.

[Q]

Hi everybody,
I have been following XDA for years now and have always been able to find answers to my questions here regarding flashing for a HTC Desire, Galaxy SII or my current Galaxy S4 I9505, rooted running a 4.3 GPE rom. Baseband is XXUDMB. Recovery is CWM 6.0.4.4.
After following the thread GOOGLE EDITION 4.4.2 by Danvdh, Kryten2k35 & Ktoonsez I decided to flash. Love this rom, it's superfast!!! One thing didn't work for me: the phone kept losing connection with my Dutch mobile carrier Vodafone (no data, phone calls not possible), especially after locking the screen. To my understanding the rom does not ship with LTE of GSM modems, so it should not be the problem that a 4.4 LTE modem causes sound, data or WiFi problems when on the "old" bootloader (pre KNOX). After flashing the baseband still shows XXUDMB.
I tried *#*#4636#*#* and setting network type to GSM. However, the menu is not the same as my current 4.3 and the option LTE/GSM auto (PRL) is not available.
Reverted back to my 4.3 rom for now, but really hope somebody knows how to solve the issue.

[Completed] [q] sprint s4 to at&t s4

OOOKAAAYY.....after many months of flashing and downloading files. I managed to get AT&T firmware, and modem onto my SPRINT SPH-L720T. I believe it happened after I got rid of anything carrier based, and flashed a google based rom, and then flashed AT&T firmware, CSC file, Modem, and Kernel. Heres the catch...when I did this I lost root and went back to stock recovery. It takes a while to boot, but the at&t firmware loads even with all the AT&T bloat apps, However my baseband is still stuck on L720TVPUBNC6 which is the baseband for sprint galaxy s4. Originally I upgraded it when it still had sprint firmware all the way to android 4.4, but after all the flashing to KK Rom, Cynanongenmod, liquidsmooth etc until the present I cannot change the baseband even when I flash with odin or from recovery mode on the sd card. Do I need to reacquire root , and a custom recovery to do this? Ive spent so many days, and hours doing this, and im finally on the edge of converting this phone completely to AT&T from sprint. My wifi also does not work which I believe is related to to mismatched baseband. Can anyone help?

Samsung S5 Help

I decided to experiment a bit and used this rom "http://forum.xda-developers.com/galaxy-s5/unified-development/rom-cyanogenmod-13-0-android-6-0-t3237502" which is CM13 with the experimental 6.0.1 on my S5. Everything worked flawlessly except I cannot use my signal at all. I decided to mess with my APN settings but couldn't get it to connect to no avail. I want to downgrade back to my phones stock firmware (5.0). Can anyone help?
Also my phone model is a SM-900P. Its the boost variant but they're interchangeable between the Sprint/Boost variants.
If possible, I would like to just downgrade back to 5.0, but if anyone could help with restoring my signal on 6.0.1 It'll be greatly appreciated!
