THIS IS A WARNING TO ANYONE USING
THESE CODES ON THEIR PHONE
***********************************************
If you enter into Engineer mode
DO NOT SELECT & DO NOT EVEN HIGHLIGHT
the "High Speed SIM" option using the stylus or finger,
you may easily brick your phone,
making it virtually dead,
and you will have to flash it to get it to work again!
Always use the side volume control button to navigate the menus
while in Engineer mode, that way an accidental selection of an
undesired option may not occur, and it is much safer! Only use
the stylus when you absolutely want to select an option!
***********************************************
Many of the settings in this first post have not been tested to work properly
on the i9/i9+ cell phones, read other member posts in the rest of the thread
that have correctly identified codes which work at least on their version of
the i9 phone, as there is less likely to input a code which will make your
phone inoperable! If you brick your phone (make it inoperable) by using an
input code, read the forum FAQ Upgrade & Flashing section (here), because
you may need to flash your phone with a new firmware to get it to work again!
To use these codes open up your phone's dialing pad to enter them EXACTLY as shown.
Many codes will work as soon as the last character in the code is entered
into the phone, usually the codes for Engineer or Factory mode & the version
summary information work like this, however, some other codes, such as those
for setting languages, may need you to enter the entire code, then tap the dial
button to activate the code.
If you find these codes do not work on your phone, & you are looking for specific
codes that do work on your phone, then ask about them in this thread, & do not
open up a new thread on the forum asking about what codes will work. Please
only use this thread to post new codes or ask for codes, all other discussion
is off topic and will be removed, thanks.
***********************************************
WARNING, the below codes may very well DISABLE Engineer mode on
many phones, and the only way to enable Engineer mode again is to flash the
firmware back to the phone again, or at least flash a small data user area of
to phone firmware to clear it, so DO NOT USE these codes on your phone!!!
Besides these exact codes, DO NOT use *ANY* code that has 6810 in it
as it is probably the same disabling code as the below codes!!!
*#6810#
*#681000#
***********************************************
Engineer mode - While in this mode you can change many of the phone's
default settings, but be careful, you can also brick your phone.
The most common Engineer mode codes for current models are these:
*#82043036#
*#3646633#
*#9433646633#
*#9923646633#
*#8560968#
*#88883209#
*#3656565#
*#3333# (note:seems to work on some phones that use *#6666# for Factory mode)
*#010101*#
*#666# (note:seems to work on phones that use *#777# for Factory mode, and *#555# for Version Summary)
Factory mode - In this mode there are also some tests & settings. In this mode
you can also find out more detailed information than just version information,
like what processor chip (CPU) the phone has in it, usually under the BB chip menu,
and some other hardware/software on the phone version numbers.
The most common Factory mode codes for current models are these:
*#66*#
*#66#
*#09*#
*#94366*#
*#99266#
*#6666*# (note:seems to work on phones that use *#3333# for Engineer mode)
*#36*# (note: works on many phones which use *#82043036# for Engineer mode)
*#258#
*#777# (note:seems to work on phones that use *#666# for Engineer mode, and *#555# for Version Summary)
The most common Version Information mode code for current models is this:
*#8375#
*#4853*#
*#555*# (note:seems to work on phones that use *#777# for Factory mode, and *#666# for Engineer mode)
*#9928375#
Odd, but some phones are using what was typically the code for setting the default language
so if the above codes don't work for Version Information, try the below code.
*#0000#
The most common IMEI number showing mode code for current models is this:
*#06#
