Well, hello guys. I have came here because I have no idea what to do right now. I bought what I thought it was a Samsung S4 GT-I9500, but now I'm not sure. For you to know, this is my cellphone's review: dhgate.com/product/i9500-1-1-quad-core-mtk6589-s4-android-4/163955856.html All my concern started when I bought a Claro SIM from Argentina. I insterted it once, no sim insterted, tried a couple of time, recognized the Operator Claro AR, but no signal, no conection, only emergency calls. I thought well, SIM must have broken when they cutted it. Due lack of time I didn't do much after that, and 2 weeks passed. Now searching in internet about how to make battery last longer, I found how to root my cellphone and I said HELL YEAH, I want to control it all! I didn't have my cellphone with me, so I just kept reading and watching tutorials, you know, recovery & download mode, CWM, ODIN, much things I wanted to do. One thing I wanted to do also was to download a ROM for my cellphone, a firmware that was for Claro Argentina. GT-I9500 Galaxy S 4 PDA: I9500UBUBMG1 CSC: I9500UWABMG1 MODEM: I9500UBUBMG1 Then I got my cellphone back, and here started my worries: 1) Vol Down + Menu + Power don't get me to the Download mode, instead I got to a "Factory mode" in chinese, or some Asian languaje, wich of course I don't understand. So had to change my strategy to root. 2) KIES does not recognice my cellphone, in fact, my device name in the PC is similar to "Android MT65** device". The "SAMSUNG_USB_Driver_for_Mobile_Phones" does not much I can say Had to change it one more time 3) Downloaded SnapPea, cellphone on USB Debug mode, plugged, everything seemed to be fine, and then I should have recieved the RSA key on my android... nothing. I turned ON and OFF the USB debbuging mode at least 100 times, cellphone plugged, unplugged, turned on and off the phone, restarted the computer, uninstaled Samsung drivers, uninstaled "Android MT65** device". NOTHING, never got that ask box. So I couldn't use Impactor 4) Time for some PdaNet, tried version 4.15, 4.01 and 3.00. I tried not reinstalling the drivers, reinstalling the drivers, uninstalling manually every single android driver on my PC, tried with Samsung and Other. All I got what, in version 4.01 and 3.00 "Error trying to handshake the device", and with the lastest version: HTC Sync error = -1. I didn't even have HTC installed, but i downloaded and installed it just to say "hey, I've done it, now what will be your excuse?". from this point on I got no more idea to go, but I kept searching, and I could do nothing. Now, there are some details i want to share with you about my "Samsung Galaxy S4" if I can call it like that. 1) My boot logo is not Samsung GT-I9500 and whatsoever, it is a green Android and "Android" written below, and then a blue thing flying arround a blue android. 2) My battery last TOO little, in use with Wi-Fi and playing, it can last 3, 4 hours at 100% charge. Sometimes it doesn't charge to 100%, and usually it shuts down (and I don't mean the "shutting down" message, no, it's like it dies from one second to another) between 15% and 13%, never seen less than 12%, and sometimes even before telling me "low battery". But well, that can be a battery problem, at least I can try to download something to regulate battery consumption, or if you can suggest something. 3) This one is funny: My storage settings: Internal Storage: Total: 12.98 GB Aviabable: 89 MB Applications: 785 MB Cache: 21 MB SDCard: Total: 17.90 GB (Hey, I didn't know my old 2GB SDCard could do that!) Aviabable: 474 MB App: 832 MB Images: 704 KB Downloads: 1 MB Cache: 55 MB Hilarious, isn't it. I thought it was a smartphone. 4) Something I crossed just wondering... my IMEI: 2222222222222222 / 01 (I don't know if I placed the right number of 2s, but you get the idea)... never on my life saw that. 5) All the "Samsung S4" features are not present on this phone. (all those fancy apps that starts with Samsung) Well, I think thats all what's relevant. What can I do? Can I flash my cellphone, install a CWM, get the Download mode instead that chinese factory mode, get the root access, and install a Claro ROM? What cellphone do I have? D: And here I list you my cellphone info, as descripted by the android system itself, and Antutu Benchmark.
