[Q] Serious problem with GalaxyS2 GT-I9100 SIM Card - Galaxy S II Q&A, Help & Troubleshooting

hi , im up awake for the last 48 hours searching for ways out of what im facing ! .. no use ! so i thought someone here would diffidently got a helpful answer for my problem ..
phone info :
GalaxySII GT-I9100
PDA: I9100JPKG2
CSC: I9100OJPKG1
NOT Rooted
problem description :
using it for 18 months for no problem , 48 ago and suddenly !! .. the phone can not detect or read SIM Card anymore !
ways i have tried :
read lots of threats in here and did lots of instructions but no way ..and after making sure the problem is not in the usb cable or the sim card or the PC , and i know as a fact its diffidently the phone ( hopefully software problem ) i did the next :
1- reset factory data + format ( no use )
2- tried to connect using usb to flash a new rom using odin ( usb not recognized )
3- tried different 3 cables ( the original one included ) and 2 different PCs .. ( still not recognized )
4- tried Samsung kies ( not connectable )
5- tried to install AirDroid ( still not connected ) checked another mobile with AirDroid connected to the same network , worked like a charm ! ..
so I HAVE NO WAY TO TRANSFER ANY DATA from or 2 my phone EXCEPT THE Micro SD ( external_sd )
6- i searched how to flash a rom using SD , and i got CWM.zip but it always gives me the error :
E:failed to verify whole-file signature
7- i tried another way for a non rooted devices like mine using a file called ( update.zip )
same error E:failed to verify whole-file signature
8- i searched again for how to root the mobile with SD but all links and videos refers me to using USB and Odin which is not working in my case
so im stuck and not sure if im on the right track or not !!
note: im a noob , i used to use Odin to do all these stuff ! now with the SD card ONLY way to fix my phone , i feel like i have no access over anything
could any one here advice me if the ( not reading the sim card problem ) would be fixed by flashing the rom and installing a new one ?
if yes ! how to do that using only the SD memory ! ...
Thanks

update : tried the CWM ( not touchable virsion ) still no use ..

Try inserting a different SIM card from the same carrier to se if your device is able to use that SIM card.
Edit: and get some sleep.

thanks i did sleep 6 hours , sure i tried different sim from same and different carrier , no use ! .. all sims working fine on other phones , when i try them on my SGS2 never works like they never exists ..

Backup everything, use nuke and kernel cleaning scripts to erase the device, factory reset and flash stock ROM. If you'll see no improvement, take the phone to a service center.

Backup everything - Done using SD
use nuke and kernel cleaning scripts to erase the device - how to do that using SD ?
factory reset and flash stock ROM using android system recovery <3e> ? or a custome recovery system ?

dont know about ur sim but if u want to root without using a computer then check this thread http://forum.xda-developers.com/showthread.php?t=2050297
i guess if u want to root ur phone to try one of the rooted methods to solve ur problem
its basically an app that u install on your phone and it will root your phone
btw is ur imei intact?

---

ok now trying downloading the apk to my device , regarding my imei intact ! i dont know what that means ! how can i know ? if there's a secret code to dial to get these info for you that would be great ! .

ok it seems u have a software issue related to modem.....try getting a stock firmware from sammobile or samsung-updates.com and flash the stock firmware
did u try to manually install drivers for the phone
there is a windows app called 1click root ..try that ...i believe tht comes with the drivers.
also dd u exit kies when using odin. (exit as in kill all kies processes).

i have my original stock and kernel backed up on my PC and my External SD , but i can not install them cuz the usb is not working on any computer , i tried install and uninstall kies and the gt-i9100 drivers tons of times for no use ! thats why i think the only solution would come from the SD ...
anyway .. i'll try 1click and let u know , thanks for your following and fast responding ammar

---

no problem... ...glad to help...if u appreciate it just press the thanks button :thumbup:
if u can just get root then you should be able to flash a stock firmware from ur phone without needing a computer. (do still have warranty)?

i tried my best ! do u have a way to root the device using the SD ?

---

you are using gingerbread? still...
check if you have an update available in settings

---

yeah it was very fine sense i got the sgs2 , and sure i can not do anyupdates sense this is not the original rom of the device , plus there's no sim card ! so when i click update , i get the no sim card error ...

---

do u still have warranty?
otherwise you will have to find a way to flash a temporary cwm.zip ...but ya i havent been able to get any of those to work so i cant advise on that.

---

No warrenty anymore .. Im on my own now .. And yeah thats what im.trying to do .. All jelp i need is how to do it using the sd card sense the recovery <3e> is denying all installations
