Si Emma 3 White Screen Patch; Siactivate Sporadic Behaviour - Sony Ericsson K800 Electrical Repair Manual

SI - White screen patch in Emma3
Affected products:
K800, K790, K610, K618, V630, W850, K610im, Z610, W710, Z710, W830
Description:
Emma3 has been updated and now has an implemented solution for white screen
problem seen on many different phones, e.g. W850 & Z610. Please note that it's not a
physical script which has been released, but a new set of Emma3 loaders. This affects
the initial identifi cation phase when connecting a unit to Emma3.
Please note that this solution is not applicable for all white screen problems. I solves the
recent white screen problems caused by ST memory failures.
To trigger White screen problem one can change the theme 15 times straight. This
triggers the problem on a non-patched unit with bad ST memory.
IMPORTANT!
Emma3 must be restarted in order for the new loaders to be downloaded locally to
PC. "Software Update Content Refresh" OR "Customize" MUST be downloaded in
affected phone in order to successfully and completely recover a unit from white screen
problem. Scripts used, and thus locally cached MUST be downloaded again from the
Server using "Server Search". Make sure to use a fully charged battery! Loader will
be downloaded in the initial detection phase and it is CRUCIAL that this step is not
interrupted. If detection phase is interrupted the phone can become totally
unrecoverable. It is NOT suffi cient to run Software Update or using the Update Service,
Update Service Pro or FOTA services.
Units that contain "infected" ST memory but still not got white screen symptom need
to be updated (using SUCR or Customize) in order to secure them from not getting
white screen problem in the future. If there are many units on stock or in warehouse that
need to be screened for ST memory, there is a "White Screen Memory Test" script in
Emma3 ( Service Information reference number: 14979 58607) Memory test will only
distinguish between Intel and ST. It can not tell if phone with ST memory has been
patched and hence is a good unit.

APPENDIX SI Emma 3 White Screen Patch - Activate Sporadic Behaviour
SI - Sporadic behaviour for Activate
Below only applies if you have access to the
Activation service in EMMA 3
Applicable only for: K800, K790, W850, W830, K610, K610im, K618, V630, Z610, W710,
and Z710.
Description
The latest update for above products has caused a very minor sporadic behaviour on
certain occasions (not constantly and not on all phones) for Activate.
The behaviour is as follows: During the running of "Activation" script, the phone may start
up in "USB transfer mode".
If the phone has started up in "USB transfer mode" during the time the "Activation" script
is running, the phone will automatically shut itself down after physical removal from USB
cable.
Please note, the behaviour is not harmful and does not cause issues of any kind other than
sporadic behaviour changes.
By entering "USB transfer mode" the unit will automatically shutdown when the cable
is removed, as apposed to manual shutdown normally. Either way, the unit still needs to
be restarted after the activation process to enable the activation.
We are investigating what is creating this behaviour so we can remove it, in order to
have a consistent behaviour.
