[Galaxy S II Q&A, Help & Troubleshooting] XOXOTech:
My mom got a secondhand phone from one of her customers... It was given to me (Im in Malaysia).

The box was ceramic white original Samsung i9100g cover, but the phone was black and i noticed there were second sim card slot (was taped in black to hide it, didnt realize this till just recently)

The battery was long lithium and not the ones i saw on google original Samsung S2 i9100.

When i start up the phone, it looks identical to Samsung galaxy s2 i9100 screen.

But when i wanted to install apps, because there were no "Applications" in settings. infact, many options were limited.

Being a noob in android, i thought its the OS problem without having any doubt it was fake i went on the hunt for odin and kies to upgrade the firmware, but i failed

Because, even though the storage mode can be connected to the pc, but kies/odin/adb cant recognize it despite, i've tried many drivers from samsung-htc-androidusb- pdanet...

Yes... USB Debugging might be the problem (Thats what i thought too). But i cant access the "application" in settings and i dint find any "usb mode" in the phone. (Explored it)

I kept reading on trying to fix it since i dont have the luxury to send the phone to town for repair... then again the phone is not broken to repair lol, just cant install and uninstall anything. No Markets on the android at all.

I tried to boot on recovery, vol up + power not working, vol down + power not working, vol up and down + power not working, vol down + menu + power not working, vol up + power + menu not working, vol up n down + menu + power also not working! This phone must be LOCKED COMPLETELY as everytime i do so, a 2 second of blank screen appears and the normal Samsung Galaxy i9100 screen shows up. NO Recovery Boot!

So finally my conclusion... its a fake samsung i9100 phone, so i googled on for the phone details, found htc 9100 and star 9100 but... Only to be more confused with what this phone is really.

Oh yes, ONLY *#06# code works and imei seem to be valid checked on a site for validating imei. However it is not the same as the back of the battery :(

I tried both Samsung codes and china codes to check the sofware version and hardware version, but nothing happens after typing in those codes... Went through even HTC and motorola codes and non work except the imei and the change language codes.

The Network by default is Ais/dtac/tru which are thailand operators, but the "other network" setting have china based operators, had to change them all to malaysian network operators to be able to use wap and gprs net. The back of the battery says :

its made in korea,

model gt - i9100

ssn : - i9100gsmh

fcc id, imei and sn which the imei dont match with *#06# imei.

I've done that "restore settings" and nothing changed.

here is some, screenshot below... sorry for the extreme poor quality.

Okay.................. So is it fake samsung s2 or real?? if its fake, what it is actually so i could get that USB mode working just so i can root it and install some apps or atleast android market? (is there android market in . jar format? haaa googled, and none... need to convert apk to jar... omg im straying too far from my purpose with more probs then solutions)

There is JAVA in it with JBed, but NO android market, i wonder how did it have some "fruit ninja" game and unwanted sexy apps when cant even copy the apk to the memory card to install?

Sorry for the super long question, Hope someone could help at least identify what this phone as a start to one of the solutions.
