W550i CID49 - insert SIM

[Tigerente]

Hi,
I got a 'white screen'-W550i to repair.
Okay, this was without a problem possible and phone starts up now fine.
BUT the phone only accepts two of 12 tested SIMs. In most cases phone tells after switching on: Insert SIM or press Demo.
Only two SIMs work proper.

The tested SIMs are between 3 years and 1 month in usage, also there are old and quite new UMTS-SIMs tested.

At first I thought it might be a 'hidden' SIMlock, because the working SIMs are from the same operator, but two other SIMs from the same operator don't work.

I tried to unlock automaticly and by code, to relock and afterwards to unlock again, tried to use different firmware versions without any result.

Anyone knows about such a problem or maybe has a hint, how to solve this problem?

(BTW.: phone is actually converted from red to brown and with fw R4BA041.
Primary certificate CID: 49

Secondary certificate CID: 36

save security zone and full gdfs than flash gdfs that is on the support cruiser than unlock or read codes if not rebuild new security zone than crc and unlock

[Tigerente]

No need to unlock after flashing fullGDFS
BUT the result is the same as before:
Insert SIM card or to view demo of this phone first, press Demo.

You have to unlock the phone after flashing full GDFS file.

Here's my result:
0. attached W550i to cruiser
1. flashed fullGDFS w550i (from support-FTP)
2. used 'direct unlock' function
3. detached phone from cruiser, inserted SIM (which hasn'T been recognized so far) and switched on the phone
4. looked at the screen and read: Insert SIM card or to view a demo ... bla bla bla

Same as before.

Just found out something strange:
I used a Rhode und Schwarz TestSIM GSM Phase2 and with this SIM inserted the phone also shows the :Insert SIM message.

Seems to be a hardware failure (maybe?) because a R&S-SIM should be accepted anytime and anywhere, right?

I have same problem with a w600 insert sim or press to view a demo

NAFG

[Amir-SkillZ]

Then for Sure its Hardware

I have the same problem, INSERT SIM CARD, K750i CID49

[Tigerente]

Okay, maybe it's not a HW-problem, if there are some more people with this problem.
And maybe it IS a hidden lock because today I got a third SIM of the same provider and this card also works fine.
In my case the working SIM are from reseller debitel for E-Plus network.
First card is with an UMTS/3G contract, second card is regular contract (non-UMTS-3G-SIM) and third woring card is a prepaid SIM without contract.
Curious is that the Rhode&Schwarz Test-SIM isn't accepted, because this SIM should override all SIMlocks.

BTW: What is the difference between W550i R4CA004_Beta and W550i R4CA004 firmware?
