Urgent - Lumia 800 cannot be turned on

Hi Lumia Experts!
Probably because my Lumia 800 was not charged overnight, the phone today cannot be turned on at all. Tried all sorts of Volume + Power + Camera things to reboot the phone but nothing helped.
If recharged via USB, the dead phone first shows an empty battery with only one red bar at bottom, after that just a white NOKIA stays on screen. Then, nothing more, it responds nothing to my operation, just like a brick.
Any suggestion? Please help!!
Thanks,
bbao

Hi Merengues1945,
Welcome to the forum!
If you cannot switch on the phone and charging the phone through your PC doesn't work, you may want to try the hardware key combination. Let me just remind you that this process will delete all of your data. First, press and hold the Volume down and Camera keys. Then press and hold the Power key. When the phone vibrates, release the power key but continue holding the volume down and camera keys. Keep pressing those keys until the phone reboots.
I Hope this solves your issue. Otherwise, you may need to have it checked by our technician at the Nokia Care Point.

Lumia 800 cannot connect to Zune

Hello,
I am trying to connect my lumia 800 to my windows 7 computer but zune keeps saying: cannot connect to phone. Turn your phone off and try again. (something like that, the message is not in English).
I have tried everything I could find to solve this problem but nothing worked so far.
I have tried:
- The fix-it utility of Microsoft. It says there are no problems.
- Reinstalling zune
- Turning the phone off/on
- Delete a certificate used by Zune
- Checking if the drivers are correctly installed. Device manager does recognize a lumia 800, also there are no problems detected there!
- Using a different USB cable
- Using a different computer (have tried 3 computers so far, all gave the same error message)
- Resetting the phone to factory defaults.
I need to install the update to solve the battery drain problem, but nothing works
Does anyone have some extra tips that may help connecting my phone to zune? Thanks in advance!

I just fixed it. For anyone also looking for the solution this post from the windows phone forum helped me:
(link to post: http://answers.microsoft.com/en-us/winphone/forum/wp7-sync/cannot-connect-nokia-lumia-800-to-zune/e1...
So first of all: remove the certificate following these steps
1: Go to "Start" and in "Search" type: certmgr.msc
2: Open the folder "Personal" and then "Certificates"
3: Remove the zunetuner certificate (If there are more than one, remove them all)
4: Open the private keys folder by typing in "Start" and "Search": %userprofile%\Application Data\Microsoft\Crypto\RSA
5: Rename the "S-1-5-21..." folder's name so it ends in .bak. (A new folder will automatically be created when Zune is launched and the phone connected.)
If this corrects the problem, restore the private keys folder:
1. Open the folder at %userprofile%\Application Data\Microsoft\Crypto\RSA that you renamed to end with .bak. Select and copy all the files.
2. Go back to "Start" and in "Search" type: %userprofile%\Application Data\Microsoft\Crypto\RSA and open the new folder that was created automatically.
3. Paste all the files back into this folder. When prompted with "There is already a file with the same name in this location" choose to not move the file, leaving the file in the destination directory.
4. The folder renamed to end with .bak can now be deleted.
And afterwards (this fixed it for me):
The devil is in the detail - simply deleting the certificate didn't work for me (it wasn't re-created afterwards). After deleting all the certificates you need kill the Zune auto-launcher process before plugging the phone back in

Lumia 800 cannot connect to my car's bluetooth

Got my Lumia 800 last week and i'm very happy with it - except for one thing. It refuses to connect to my car's bluetooth hands-free system.
The car is a Ford Mondeo XR5 (2009), with factory-fitted bluetooth. I've used several other phones with the car system with no problems, including my old Nokia 6700 classic, Samsung Galaxy S2 and Nokia N9. These all conenct and work fine. Just not the Lumia 800.
I've used Zune to get the latest software for the phone, and have checked bluetooth is turned on (can connect to my laptop OK).
I've spoken to Ford and they say the car system is working fine, since it can connect to all the other phones OK. Spoke to Nokia support & they refer me back to Ford .
Any suggestions would be appreciated.

Check for updates for your in-car bluetooth system, 2009 hardware is very very old by today's standards, especially since car bluetooth systems are lagging a few years behind other technology by default.

Lumia 800 Cannot Download a single App from Market...

Hello,
I've just bought a Lumia 800 on July 20, 2012 from a retailer in the Philippines and am using it in the same.
I downloaded Zune for Windows 7 on my dual boot mac. I downloaded all updates till Zune said there was no more available on the Windows 7 partition. It succesfully installed. I am up to date according to the latest firmware as noted on Nokia firmware and MS OS as of today.
I have not been able to download a single app since I got the phone. I use the marketplace app on the phone and have also tried "pushing" the app from the marketplace on Firefox/Chrome on my Mac and PC.
The phone goes to marketplace downloads, says "Pending" starts to says "Downloading 0%" till it says "Tap here" then I have to retry download. Been trying this all night, and have been reseting the phone by holding the button below the volume control till the phone says "Goodbye" then I boot it up and the same still happens.
I've also tried a hard reset, formatting to factory settings. That did not let me download a single app either. Since I needed the phone, I restored my data. I have been using a wifi connection with broadband at home. I can surf IE on the phone, check mail, but the marketplace has always been off for the few days I've owned the darn thing. I can open the marketplace app, I can see apps, I can browse them, and I can click install, reinstall (for some reason Windows Live thinks its already installed).
Am I missing something? I tried cancelling all other downloads except Whatsapp and still no dice. I've cancelled all downloads, restarted and tried again and to this day, I have an app phone that can't get apps from it's own marketplace.
I tried setting my windows live ID to jive with my region and language, all the same, US or Philippine english, nothing.
I've tried writing emails to Nokia Philippines support and after typing all this they just told me to 1. open marketplace app, 2. Click Download (Arrgghhhh talk about canned STUPID RESPONSES, the guy obviously did not read my email that I did the same.)
Please help me.

Hi kosh, Yes I have done a hard reset even at the risk of losing all my contacts. I've also tried creating a new live ID to sign in after the hard reset was made. Sadly such did not work so I eventually just restored my contacts. I find it disappointing that groups does not sync so if ever I do need to change live IDs I'll have to remake all the groups again. Such is the loss of a loyal Nokia customer who has to pay for Symbian going and ms entering. I find it odd that I would even have to create a new live account as the one already designated as the primary account attached to the phone was created upon first boot of the phone. But I guess there's no loss trying one more time since accounts are free. I'll have to do it some other time as I am currently mobile and had to leave the phone cause the total lack of apps has rendered it insufficient for my needs. I will update the forum once Nokia and/or Microsoft contacts me. Really hoping they just replace the darn thing since I bought the phone open line out of carrier making this feel more of a waste, and I wouldn't want a phone like this sent for repair this fresh or given a refurb.

Lumia 800: cannot hear the other side when receivi...

hello all.
i had recently upgraded to w7.8 for my phone, and problem started coming.
i cant seems to hear the other person when i get or make calls, and they cant hear me too.
i get this problem quite often, and i tried factory reset, and no data is loss( i wonder do i perform the resetting correectly)
i tried off and on my phone again. same thing still happen occasionally.
what is going on? PLeAse help!!!
the phone is only 2 months old and never drop/bump anything.

If you can't hear the caller THIS may be helpful ..but if the other end can't hear you then may be you need to visit Nokia Care
BTW, How did you do the Factory reset ?

Zune & Lumia 800

Everything was working as it should be until recently when i did a factory reset on my Lumia 800 due to the "unable to receive MMS error"
Now, my Lumia 800 cannot sync wireless despite the fact it's on charger for more than 10minutes on full charge. Neither my Zune starts automatically whenever it's plugged in through the USB (i have the auto startup function ticked).
Any idea how to fix this?
It's getting really irritating because i don't know what's wrong and i cannot fix it.
Advice?!

Cannot End Call Nokia Lumia 800

Hi Everyone,
I cannot end phone calls with my Lumia 800, Please can someone help? I hate having to turn my phone off to end the call.
Thanks
S.Griffiths

to end the call ,you probly :
1)dropped the phone very hard on the ground check if the glass is a little higher than usual. Sometimes after dropping the phone to the hard ground, the glass can be lifted a little bit and that impact the proximity sensor function. In many cases, it can be fixed by pushing that part of the glass back. Just give a push by your thumb and see if that happens still.. This helped me a lot and its working
2)The upper right corner of the glass may be too dirty, please clean it and see if the issue is still there.

Lumia 800 turning off randomly

hi All
I'm having an odd problem with my Lumia 800, that I hope you can help with. The phone randomly shuts down, it doesn't seem to be related to the power levels as it does it when fully charged. It can go 2 days or 5 minutes before doing this. The odd thing is that to turn it back on I have to plug it into my PC, it comes back on immediately... it does not seem to come on if I plug it into the mains. This is a recent issue it worked for a couple of months without any issues.
Any ideas? I'm based in london on an Orange contract. Thanks for you help in advance.

I'm having a similar problem, my 800 switches off in mid conversation sometimes and restarts. This is very frustrating as most of my calls are to clients of my small business. However the caller ID from that call doesn't record as would usually happen.This is not so bad if it's a current client as I can call them straight back on the landline but if it is new business I don't have that option as I have no number :-( (therefore lost business)
I am getting really hacked off with it and could do with a proper answer.

Lumia 800 Turning itself off!

Dear NOKIA, up until now I have just put up with this phone simply because it has lots of style and and I really like the look of it, obviously as you're probably aware this phone has had lots of complaints most of which are very valid points (BATTERY LIFE, LACK OF BLUETOOTH, LACK OF NOTIFICATIONS, NOT BEING ABLE TO CUSTOMIZE AN SMS TONE, NO MASS STORAGE) Over the last 3 months I have chose to put up with this but today I can no longer 'just put up with it'.......
Last night I set my three alarms on my Lumia to ensure I woke up for work on time, I woke up an hour late for work with no sign of an alarm!(5am) This probably had a lot to do with the fact the phone had turned itself off! I turned it back on, and left for work. by the time i arrived at work (5.30am) the phone had once again turned itself off! By 8am I noticed again phone was off, surprisingly at 10am I needed to use the phone and it was ON and ready to use! However by 12midday it had turned itself off again! In all the phone has turned itself off 6 times today! obviously the phone had been charged to full capacity over night so has had pretty much a full charge most of the morning? So can someone explain what is going on with it, and what is my next step, I can put up with most things (cosmetic) but how on earth do you expect customers to want to use a phone that is more unreliable than british rail in the 80's? IF there is such a thing in the nokia world as 'customer care' would they PLEASE reply to this post???
Luke, an extremely frustrated, leaning toward disgruntled Nokia Lumia 800 user

I'm having the same problem with my Lumia 800 restarting. The first device did this so regularly I had to have it swapped out for a new (well, refurbished) device. I know four other people with this device, two of whom report no problem but one of whom has had the same issue and also had to have her device swapped out. Even with the replacement, I'm noticing that the phone is restarting 2-3 times a day and there is no pattern to this behaviour. Often happens when the phone is dormant but also ocassionally when in use. Very frustrating but not sure if entirely linked to this phone as I had to change our my LG Optimus for the same reason - it started restarting after an earlier update (no longer available to me to roll back to). So, is it Windows or the phone? Either way, Nokia, really like a response to this as it's not great and having encouraged my other friend to select WP7 over iPhone, it's starting to look like bad advice. We all love the OS and the style of the phone etc is awesome. Battery life is poor but perhaps a future update will fix this but the restarting is an annoyance that can't be ignored and I'll be sending this phone back for a replacement too if the problem persists.

Turning off sms preview Lumia 800

i would like to turn off the SMS preview when i get a message. Is this not possible? i have just bought a lumia 800 nice phone...some really good features...but very uncustomisable compared to Android and IOS.

You mean that bar across the top of the screen? No you can't remove it.
What customisation are you refering to? Perhaps I can help. I have androids as well.

How to turn OFF flip to silence on Lumia 800?

Often I don't hear my Lumia 800 (1750.0805.8773.12220) when I receive a call and the volume is all the way up. I suspect the flip-to-silence feature introduced in an update in summer 2012 to be the issue.
So my question is: How to I turn off flip-to-silence??

Another thread has the same concern and the answer was provided here.

Lumia 800- country code (e.g. +852, +86) cannot be...

After upgraded to 7.8, i found that the phone call with country code cannot be recognized.
For example, a contact "John" with number : +852-999999 is saved in contact.
In before, no matter the incoming number is 999999 or +852-999999 or +86 999999, it can still be recognized.
(the phone can smartly determine which part is the country code)
however, after upgraded to 7.8, it cannot be recognized anymore.
Vice versa, if I save 999999 for John in the contact, if i am overseas and receiving the call e.g. +86-999999
it will show "unknown" because +86-999999 is not saved in contact.
I have tried the same sim card on another WP7 phone, iOS phone and android, it is normal (same as what i use before)
This is very annoying.
This problem is never found before upgrade.
If anyone have idea, please feel free to advice.
Thank you

Hi all,
Thanks for your feedback and patience. In order for Lumia 800s with product code 059M539 to be updated to the current firmware revision we would like to ask you to visit a Nokia Care Point to have your device updated.
Please make sure you have your contacts and calendars synced with the services you use (Hotmail/Google/Exchange) and you have all your media files synchronized with your PC (through Zune) or Mac (through the connector). In case of a required hard reset these files and personal data will be deleted from the Lumia. After the update you can use the app Reinstaller to download all your free and paid for apps back to your Lumia.
Again, thanks for your patience.
