[Tilt, TyTN II, MDA Vario III General] pepesr:
NEW (29/4/09) --> after further investigation and discussion with other kaiser owner affected with same problem, the thing could be more important than expected as many Kaiser could be potentially having the same problem.

The issue is that after going on flight mode the unit can start to have problems to get registered to the phone operator. Sometimes the problem is mitigated temporary by disabling 3G but the problem can persist. The unit is able to see the operators available but not to connect to any of them. Units affected were built between 07/07 and 11/07.

If you are affected please post your release date (DATE: DDMMYY(TBXX)/EU) that you can find on the sticker on the atenna in the back, under the back cover.

If you are not, be aware of the problem as you may start to have it if you go to flight mode or travel abroad.

NO SOLUTION FOR THE TIME BEING, AND IN GENERAL AFFECTED UNITS ARE ALREADY OUT OF THE GUARANTEE PERIOD.

----------------------------

My TYTN II has more than 1 year.

The problem

: Basically it is out of coverage all time, and does not manage to get connected to any network.

It started about 1 year ago. I am base in France and I want to USA. When I arrived to New York it did not work anymore. I thought it could have been the roaming or just that I had changed the SIM card a few weeks before and the operator did something wrong (ORANGE). But the point is that the same SIM was working in my spare nokia and on the other hand an Orange Spain SIM had the same problem.

I spend a few days in USA moving from one state to the other and after 2 or 3 days the phone started to work but with some problems (changing from one operator to another it did work) finally the 4th day it was working.

When I returned to Paris, it did work ok for a while.

Then one day the phone just droped the connection to the operator, and at the same time the Bluetooth link to the BT carkit and the GPS stopped and restarted. Since that moment the phone just did not work anymore (only the telephone).

I open a case to HTC who never replied. On the phone they just say inconsistent things.

The WM6.1 official release came out and I did upgrade it--> still the same. A new ticket open to HTC without replay. I stopped using it for a while.

In summer I went to Spain for vacations and started to play with it again. One day it started to work again without any justificiation.... so I left it like that.

Months latter I got a mail from HTC (really very reactive) but at that point the phone was working since more than 4 months.

By the end of 2008 when I was in Spain and this time using my Orange Spain SIM, I had to replace the SIM. After a few days, and after travelling across Spain, I had again the same problem. And actually the phone did not get any coverage with any of the SIM I use (Orange FR, Orange ES, Movistar...). Little by little it started to work again and it has stay like this for a few months.

In the last few weeks I have been in UK and Italy. Again started to have problems and finally, after a visit to Italy my phone has stop working. It is like that for 2 weeks.

The point is that I have tryed all kind of things:

- force to GSM or let it in auto

- change the UMTS and GSM bands

- different SIM from different operators

- Official WM6.0 and WM6.1 spanish

- finally I started to flash different Radio ROM and also coocked ROM

- when I search manually the operators or I try to fix it manually, I see that the phone is actually capable to see the available networks, but it does not manage to get registered in any.

At the end it is always in with the "!" symbol, saying either that it has no coverage or that the access is refussed.

I have seen that in two occasions I had changed the SIM a few weeks before. Also that the problem has always happened after putting the phone in flight mode (actually I was flying) and landing in a new city or even a new country; except once.

Last point: it is free HTC Spanish version. It is actually the second as the first I had was stollen. With the first I never had problems.

I will end up sending it back to HTC but obviously it will take very very long and meanwhile I will not have the GPS and the rest of the PDA that still work ok.

Any idea?

Thanks
