[Q] Downgrade Android Baseband - Android Q&A, Help & Troubleshooting

Hello to all the great community,
Generally: I want to install miui v5 on my mobile (LG P700 or L7) but i have previously installed (2 months ago) the kitkat 4.4.2 version with the v20f baseband.
The problem: The problem is that in order to install miui v5, i must have baseband v10k on my mobile..
The question is: Can i flash the older, v10k, baseband on my mobile via, only, the cwm, as described here: http://forum.xda-developers.com/showthread.php?t=2335273 ??
I forgot to mention that i've already installed miui v5 ported on my phone!

[Q] How to Change Kernel to Official one?

Hi,
Recently i tried to install the custom ROM "RebornROM v2.1". In that process i bricked my LG Optimus one. After that i installed v1oe official rom using KDZ. now it's working fine. But my kernel version showing is "2.6.32.9 [email protected]#1" , How can i change this to my official one. My official one is like this "[email protected]#1".
And now when i restored my original v20c india version using CWM recovery, the SIM Card didn't detect. I think the problem is kernel.Help me any one. Thank You.
nope, the problem is with baseband bcoz V10 baseband is for stock 2.2 , 2.1 and V20 baseband is for stock 2.3
follow picture guide to upgrade your baseband to V20 and you will have your sim detected and gsm working on your original v20c india version

[Q] upgrading OS

Cn zte v9c be upgraded from android 2.3.4 to any other higher versions. If yes, plz tell me how.
ZTE v9 is supported by Cyanogenmod, not sure if its any different from the ZTE V9c. There are CM9/ICS ROMs there for it. Check Rootzwiki or the Cyanogenmod website for more info.

[Q] Roms Customs Mini pro SK17i

Android : 4.0.4
Firmware : 4.1.B.0.587
Baseband : 8x55A-AAABQOAZM-203028G-77
Rooted with Eroot
I would like an advice (Recommend) on the current Roms.
Thank you for help me
I'm sorry but asking for the best rom/kernel is not permitted. Please try some roms and find the one working best for you

I ask not the best but it advises on rom install and to install app to sd
What roms are the latest 1 jellybenn and 1 katkit ?
And you you have a preference ?
App2SD should work on most roms, I guess nearly on all roms
Check the development forum, there are already many jellybean (Android 4.1.2/4.2.2/4.3) and some kitkat (Android 4.4) roms you could try

I've used the MIUI rom for s3, and trust me, it's really good. The only downside is that you have to downgrade to android version 4.2.2 which is CM based. The latest version is based on 4.2.2, not 4.1.1
You have to do this:
1) Root your s3 following a proper guide. There are plenty on the net. Just google it.
2) Install a custom recovery. I recommend TWRP or Philz Touch recovery.
3) Download the MIUI rom from their official website en.miui.com
4) Flash the rom using the recovery.
Done. Hope this helped
