technical question-hardware E1

Hi

The ROM used for storing IMEI and other factory programed data at point of manufacture,

is it EEPROM, or one time programable, ie internal fuseble links on the chip wafer ???

I doubt if there is anyone on this forum can answer this, but it may let me know if I have what to me is a E1 brick

or a phone I can use

It's on the EEPROM as well as other info or some may call it the NAND

[richard-g8jvm]

Thanks

If Sony have moved entirely to the use of NAND Flash memory and the one time protection bit is set, which on the service menu

is indicated that it is set, it means my phone is a brick now and can only be used on one network.

Which leaves me pig sick !!!!!!

Are service exchange pcbs available for a E1 ?, as it looks like its the only way I can use my phone on another network ?

I take it you have checked the service menu to see if you have a hard locked phone or if you have unlock attempts left, if you have then I believe Sony service centres can reset this but don't quote me on that - I'm merely repeating what I've read

Hi Thommo

Yes I have checked in the service menu and its hardlocked, It should be at the moment at the Ashford ,Kent Service center

1-17824485515

I've given up with VF, their training of staff is so bad, they dont know the difference between hard locked and soft locked,

they think hard locked means blacklisted.

I've also checked the various manufacturers data sheet s on their NAND Flash, and depending on which manufacture supplied the NAND Flash to the 

factory will determine the action of the one time only function on the NAND.

All I can do is hope that someone at the service center can apply some common sense, I'm at the end of contract with VF , I would like to be able to use the xperia phone with my new provider.

TIA

have you contacted Sony directly?

Yes I have contacted Sony directly on the url given, the woman was not very helpful, I was not satisfied with end answer of put up with it.

Its in the service center at Ashford Kent,  repair number 1-17824485525.

As the handset is at the moment its effectively a brick   Absolutely useless to me

I like the xperia phones ,but I'm stuck with an old HTC desire where the battery life is awful on 3G, and I'm now on a 3G only provider.

After all it was Sony who set the one time only bit on the NAND flash

[Uliwooly]

The issue is that you entered the wrong unlock pin, who gave you that pin? perhaps you might want to contact @Rickard directly, he might be able to guide you.

[richard-g8jvm]

I have not entered and unlock code, I have only enetered the service code to verify that in can ne unlocked

[richard-g8jvm]

Furthermore, you have made an accusation without fact, 

The first line of the SIM LOCK menu read :-

[o] Network 5

Had I done as you have accused me of the "5" would be "0", the 5 shows there are 5 attempts allowed. but

[o] shows the feature has been disabled when that section of NAND was written to at the end of the pruction line, when the IMEI was entered.

As a seniour memeber of this forum to make an unfounded accusation is unwarranted, and I hope a moderator will step in, 

You should be stripped of any rank earnt on this forum, and IMO opinion barred from any postings.

and I want an apology from you

This is suppose to be a forum to obtain help, as it is an official sony forum a formal complaint will be made
