Very high chances for the htc recovery you are too lucky to find programmed emmc 
i remember once i also got a programmed flash chip the guy whow would be replacing has less hassels to face as he can try instantly without fiddling with a computer . Anyway later a flash will be needed and i am out of town so cant view the 900 kb picture on my 5610d will have a look after h get home
i have schematics of it i will tell what to check just wait

I just got an e-mail from the service and the price for replacing that part is 200RON (Romanian money) that is equal to 45 EUROS. So I'm pretty much under half of the devices value, so, I'm okay with that. And yes, another Desire user bought a chip like that, installed it and the phone booted for the 1st time without any additional programming. So yes, I can say I am pretty lucky!
And about what I need to check... DON'T! I won't check anything by myself that is that small and fragile. I will stick to my old bulky hardware knowledge, where a soldering iron is all you need (amplifiers, mixers and stuff like that). Give me a list, and teach me what to say to that guy in service.
Thanks!

I really hope he know the right temperature for the motherboard, how to apply flux, and other soldering knowlege. However i lost my trust in services long ago.

I was waiting for a schematics so I can show that guy in service exactly what to check for the N900.
The HTC is as fixed, no worries for that phone anymore. I trust this service because, they have only positive feedbacks about their fixes.

Print the level 3 and 4 and give it to them it will be of little help as you said they were able to replace an ic i will say they are damm good and delligent as i dont have a n900 and coudnt look your pic closley hard to say what to check let me go home and check the schemas
just dont tell them you used soldering iron or they will go crazy and charge a lot like i do

P.S. I will send the motherboard in service on about 25th of July, because on 25th this month I will get my paycheck and order the memory chip for the HTC, after that I will wait for about 1 month for the order to get in my country.
P.S.S. For each and every one of you, and I will post this even in the repair wiki that I created, please go to your local Orange store and make insurance for your phone. For my new HTC 8s (brand new with 2 years warranty) I pay 3 euros per month for full extended insurance meaning I get a new replacement phone ON WHATEVER PROBLEM MY PHONE HAS and it doesn't matter EVEN IF THE PHONE IS EXTREMELY OUTDATED I will get an exact replacement (not another HTC model, not a Nokia, not a Samsung, but EXACTLY a brand new HTC 8s). Insurance covers every hardware problem I could get. Ex: I dropped the phone broke the digitizer and the LCD, the insurance will cover it. I broke my USB port, the insurance will cover it, and so on. Go there, get informed. Here is a link: http://www.orange.lu/phone/options/m...nes/index.html for Orange Luxembourg (I went here because it was the first result IN ENGLISH and not my LOCAL LANGUAGE).

All times are GMT. The time now is 03:31.
Does somebody have the schematics for the N900 GSM Chip and what needs to be checked/replaced?
I have this picture uploaded with a close-up, now, which is the driver, and what to search for? (I touched all 4 of them with the soldering iron, so all 4 of them may be out of place)
Tips?
