salutare! i have a problem with the new fresh installed rom, the Lion Jelly Bean 4.1.2 ROM for Galaxy S2 GT-i9100, V1.3.

I installed a new modem driver, the BULP8 corresponding to vodafone romania and nothing changed.
I habe the 3.0.31 jeboo Kernel v1.1.
How can i resove this problem? pls, help.
thanks

[Q] [Tipo] AdHoc connection

Hello,
I am aware, that this problem is known, but I did not find a solution for the Tipo. So I decided to start this question thread.
I am facing the known android problem with the AdHoc connection. The Tipo I am using is rooted and has the stock 4.0.4 rom.
The forum provides some solutions for other devices, but I did not find one for the Tipo.
I tried the methods HEXcube, kurotsugi and Maxxd01 are suggesting, but they did not work for me. If I got it right, the wpa_supplicant file has to be adapted to the specific device.
So here is my question: Is there a fixed wpa_supplicant file for the Tipo?
Or what has to be adapted in the file to make it work?
What is interesting: If I use the "WiFi Manager" and the "Smart WiFi Scanner" app, the AdHoc network is recognized by the Tipo, but I can not connect to it.
The connection to the device I want to communicate with, works with the iPhone and my laptop.
Thanks in advance for any help!
What are you trying to do? Stream files via wifi adhoc? The only wifi that works with tipo are wifi ap (share tipo internet connection to others) wifi to router and wifi file transfer.
Now using:
Sony Xperia tipo ST21i
stock 4.0.4
11.0.A.4.22
(rooted, locked bootloader)
Current problem:
Cant get past installing flash drivers in xp.
First of all, thanks for the quick reply.
Right, maybe I did not point out well what I want to do.
The goal is to connect the Tipo to an AdHoc network provided by a wifi device on a microcontroller board and to transfer some data. This device is only able to provide an AdHoc network.
The standard android 4.0.4 cannot connect to AdHoc networks. So what I want to do is to modify android so it can access them. This should work with a modified wpa_supplicant file made for the Tipo. Now I am looking for such a file or a well described method to change the standard wpa_supplicant, since I am not that experienced with the Linux programming.
this problem happened with me on my Miro, stock and rooted.
i tried finding answers on web but could not. then i think i restored everything and noticed that the problem had gone.
maybe you should try that!
I tried it and it did not work for me. But AdHoc did not work from the beginning, wenn the Tipo was already stock.
Thanks anyway!
Does the device kinda transmit wifi signal? Like some kind of wireless ap? If thats the device, I know it worked on tipo. If its Adhoc file transfer via wifi, it seems android cant recognize it (detects ap, wants access internet, but no access to wlan network - using xplore).
Now using:
Sony Xperia tipo ST21i
stock 4.0.4
11.0.A.4.22
(rooted, locked bootloader)
Current problem:
Cant get past installing flash drivers in xp.
Yes, the WiFi device sets up an AdHoc network (no wireless access point, no internet connection) and I want to connect the Tipo to it and receive data.
I do not want to connect the Tipo to the internet through this WiFi device.
As you said, Android does not recognize AdHoc networks in its own wlan network list. But with the apps "Smart WiFi Scanner" and "WiFi Manager" they are visible on the Tipo.
Although Android seems to detect AdHoc networks in principle (with the help of the apps), it cannot connect to them. And that seems to be "a general" problem with Android (at least 4.0.x).
Now I would like to modify Android so it can connect to AdHoc networks. That should work by adapting the file wpa_supplicant (in /system/bin in the root directory) to the Tipo configuration.
I will add the threads I mentioned in the first post (I hope the quoting is right):

Hey you're right about the wpa_suplicant file..but the thing is even i could not find that file nywhr.
Btw r u tryn to share ur internet frm a Windows pc? If yes, u shud try a program called 'connectify'.
I have been through this prob,i dunno what happened later but it got away somehow.
Good luck!
Sent from my ST23i using xda premium
Hes not talking about internet connect, its wifi adhoc so he can send files just like netbook adhoc wifi file sharing. It just that the phone cant seem to know LAN file mode, I think android only wanted internet on wifi. Maybe using some ftp client via Lan wifi adhoc?
Now using:
Sony Xperia tipo ST21i
stock 4.0.4
11.0.A.4.22
(rooted, locked bootloader)
Current problem:
Cant get past installing flash drivers in xp.
I also tried HEXcube method but it doesn't work for my Xperia Tipo?
Any idea?
