[Galaxy S III General] E:V:A:
Special Properties

Next we'll have a look at some interesting (or not?) system "properties".

For now, I'll just list some of those I found more interesting and potentially useful.

[SIZE=2]Property Setting/String Source Description[/SIZE]
[SIZE=2]----------------------------------------------------------------------------------------------------------------------[/SIZE]
[SIZE=2]dev.silentlog.on On SysDump: [/SIZE]
[SIZE=2]gsm.operator.numeric 45001 Sec_Ril_Dump: [RIL::FD] Samsung Testbed[/SIZE]
[SIZE=2]gsm.default.sidmode ? UART[/SIZE]
[SIZE=2]net.tcpdumping On SysDump: ?[/SIZE]
[SIZE=2]nfc.trace.mode On Enable NFC Trace Mode [/SIZE]

[SIZE=2]ril.FTM_MODE ? "FTM_MODE_KEY"[/SIZE]
[SIZE=2]ril.FS true PhoneUtils: updateRAFT() Activates RAFT (???) updates[/SIZE]
[SIZE=2]ril.OTPAuth SysDump: OTP Authentication [/SIZE]
[SIZE=2]ril.cdma.inecmmode true Is phone in ECM mode?[/SIZE]
[SIZE=2]ril.unique_number The RIL Unique Number (UN)[/SIZE]
[SIZE=2]ril.sms.gcf-mode On ? SMS "GCF" mode[/SIZE]

[SIZE=2]persist.log.seclevel On Switchable Log level?[/SIZE]
[SIZE=2]persist.sys.country [/SIZE]
[SIZE=2]ro.build.type eng SysDump: [/SIZE]
[SIZE=2]ro.debuggable On Enable Debug / DBG_ENG / Engineering Mode??[/SIZE]
[SIZE=2]----------------------------------------------------------------------------------------------------------------------[/SIZE]
[SIZE=2]Country/Region Specific[/SIZE]
[SIZE=2]----------------------------------------------------------------------------------------------------------------------[/SIZE]
[SIZE=2]ro.board.platform [/SIZE]
[SIZE=2]ro.build.characteristics [/SIZE]
[SIZE=2]ro.csc.sales_code SKT | KIT | LGT PhoneFeature: makeFeatureForKor() [/SIZE]
[SIZE=2]ro.product.name espressorf | espresso10rf PhoneFeature: checkDBGLevel() [/SIZE]
[SIZE=2] aegis2vzw PhoneFeature: makeFeatureForKor() [/SIZE]
[SIZE=2] jaguars | jaguark | jaguarl [/SIZE]

A particularly fun string is the following, found in the featureForKor() function:

[SIZE=2]mFeatureList.put("emergency_for_cyber_terror", boolean2);[/SIZE]

I'd really like to know what this does!

Special Files

As we know from other Samsung Galaxy class phones, there are a number

of files that can be created or modified in order to activate certain

functions. Here we list those found to date. Please post if you know

of other ones!

Apparently setting the "SubscriberID" (IMSI) to "999999999999999" also

activates certain test features. A sim with this IMSI is also known as

a "Factory SIM". However, if the SIM IMSI starts with either "45001" or

"00101" it is a "Test SIM".

[See: ServiceModeApp.apk:PhoneUtils.java:isFactoryMode() or

FactoryTest.apk:ModuleCommon.java:isFactorySim()]

[SIZE=2]File FileContent Description[/SIZE]

(Note: Some of these paths need to be verified, as they may be relative...)

Finally, we have two NVpasswords, that is used for uploading or dumping NVram, AFAIK. They are:

873283

3352225

and they can be found in Sec_Ril_Dump.class.

DISCALIMER:

As I do not have access to a GT-I9300, I have not been able to verify

any of the information in this thread! I apologize if there is any erroneous

information here. Please let me know and post new information here as

it become available. Also make sure you make a complete backup, before

attempting any of the codes or other trickery above!
