[Q] Lumia 900 Help to Unbrick - General Questions and Answers

Guys I will be grateful for any help you can give me here.
I have a Lumia 900. I was receiving the notification of the latest update but didn't and never attempted to install it.
Last night it give a critical low battery warning and I connected it to the nokia lead and mains charger.
It was left over night to charge however this morning I found it in a boot loop.
Buttons on bottom light, then white screen, then NOKIA logo and back to black screen.
I can't turn it off, it just runs until out of power.
I managed to get it into the mode with phone and computer displayed and Zune connected, however I have no restore points or backups.
All help much appreciated

Help! Noobie - can't get it to turn on!!!

I can't even turn my Newish XDA Exec on!!!
I received it this morning and I just get the 02 flash screen to come on for a couple of seconds then it goes blank... it's doing this over and over.
The charging light comes on for a bit too (was ok for awhile - staying on all the time) now it goes amber then red while the splash screen comes on then everthing goes dark!
Pleeeease don't say it's broke
I've tried charging with the charger but the light is red so it's now plugged into my pc and going on and off...
I forgot to bring the CD with me - is that needed at this stage? ie: just turning the thing on? is there a site that I can download the software from rather than use the CD?
*sob* gonna cry soon...
it has small letters in the top left screen R G D with numbers next to them (what does that mean?)
Would really appreciate some help and advice please.
Thank you
(Happy New Year )
Welcome to the forum.
First don't cry
Second, check if the battery is connected tightly and correctly.
Then turn it off and connect it to a wall charger (not PC) and let it charge for at least 6 hours (unless there is a red light).
If there is still a red instead of orange charging light this means the battery is bad.
Since it is new it should still be under warranty.
As for the disk there you do not need it. To transfer files and synchronize outlook info to your PC you need MS ActiveSync which is free and available on MS site.
Hi
I've not started crying as yet but on a slippery slope to a good sulking!
Is it suppose to be flashing red? (I don't think it's amber!!) (do you think if I went into a shop and got them to test a battery to see if it works with a new one - but I wouldn't buy it from them - cheaper to buy online)
I would have thought I'd get something as it's been charging now for about 3 hours (on and off - I've been trying the usb cable every now and then which is when I get the flash screen to come up for a few secs - don't get anything when it's in the normal charger).
(I've brought this 2nd hand so no warranty! my mobile phone, which this XDA is suppose to be replacing is new but o2 said they wont fix it and it's only 7 months old!!)
thanks for your help
It's working!!
I did think that the flashing red colour was wrong.. was told it was suppose to be a solid colour.
Phew.. I was getting very worried!
it might need a new battery at some point - but at least I know it works
Thanks for your help

Phone Not Charging!!! (HTC Desire S)

Its all in chronological order. As the title says my phone wont charge. USB CABLE from PC or wall charger it just wont charge. Following some threads i also removed the battery and connected it to main but no led would show up. Right now i've removed the battery and charging on universal charger fine,
So here is the history. I dont know what can cause it not to charge. While i was at university my phone fell on the ground. It was not from height as i was just sitting on the sidewalk and it fe ll down. Then I came back home. I have ICS Ruu Saga on it which i'm not happy about and wanted to go back to GB ever since i realized that my camera quality is worse than before and my Subway Surfer game is not smoother any more,
Seeing some threads I selected the recovery option in bootmode (vol down+power). After few second a red triangle came showing ! sign. I removed the battery and re-inserted as the power key wont work. When i re-inserted the battery and powered up but it was different boot method. before selecting recovery option the booting of phone was smooth..but after that it stucked for a few seconds first and then came the home screen.
After all this as my battery was getting low i decided to put it on charge. I connected USB Cable to charge it and realized after sometime it isnt being charged,,,there was no orange led that usually indicates its being charged.
So thats all. I dont know if dropping the phone was cause of it or doing recovery ( note: i never made a backup of my phone every..i dont know why i did it, in hoping that it would go back to GB itself) and the appearing of red trianlge with ! mark and me removing the battery did it.
Please help me. I spent entire night on finding the solution but couldnt find anything.
Phones warranty is over..Its not rooted or has CWM as i dont know that stuff.

At&t Lumia 900.1.....Restart loop

I have a nokia at&t lumia 900.1 RM 808 that has been looping since the battery went dead. I tried almost everything on it. I did a couple of hard reset, hold the power button for more than 10 minutes,left it on the charger but it keep turning on and restarting which killed the battery, so i took out the battery and charged it manually but still loops. I tried flashing it with best dongle, ADPS, AMSS went through but the UDA keep giving error say i must check usb or battery even went it full, and WP did not detect by best dongle. Those are the only files i got from the best dongle site/server. When i also put it in a mode nothing shows on the screen but my pc picks it up the phone and the mode. Could i please get some help on this, thanks in advance.

Does your pc detect anything when you plug usb cable ?
Yes, it detects, but then disconnects, can it be a problem in the battery?
Chances are you have received a refurbished device or defective battery.
Try and find another Mi4 user for trial of the battery or let's see you need to contact the vendor soon.

Charge via wall adapter. Leave it for some time.
PS: When your battery reaches 9-10%, it is advisable to charge it back to 100%.

I just got this issue 10min ago. Havn't depleted the battery on the phone for a very long time, my guess is that it hasn't calibrated the battery in a while or something like that. Will keep it in the fast charger during the night and then i'll reply here.
EDIT: Normally the red LED is constantly on when the battery is low and it's in the charger, now it's flashing which makes it look a bit more scary.
EDIT2: Works fine now after a night of charging
Charger could be not pushing enough voltage to charge battery. Try another one to see if it remedies the issue.
I do have the same problem with my Mi4. I wanted to start the update in the Updater app (to Android 6 version of Xiaomi.eu) and suddenly it turned off (at 100% battery). When I connect my phone with my computer it is recognized and all the partitions are mounted. And with all I mean all. There are about 7 partitions mounted (Linux and Windows) and they keep being mounted until I disconnect the phone. I let my Mi4 on the wall charger for 24 hours (2A Samsung one which charges all my other devices without any problems) but I still have the blinking red light after connecting it to the charger. Any other things I can do to get it running again?
EDIT: I can't see the phone in fastboot or adb and when I keep the power button pressed for about 10s it seems to disconnect and instantly reconnect the phone.

I solved this problem on my own. Even though the phone doesn't show up on the fastboot devices list you can use the Mi Flash Tool to flash the fastboot update (http://xiaomiadvices.com/miui-7-flash-fastboot-rom-on-xiaomi-phones-using-mi-flash-tool/). The drivers installed with the Mi Flash Tool for the Windows 10 Mobile Release (http://en.miui.com/thread-189369-1-1.html) recognize all the partitions as one device and show it with a cryptical name in the flash list.
Hi ! I fully charged the phone and after it shuted down. It doesn't starts. PC doesn't see it. When I'm plugin the wire just half way into the phone the red light stays on for a few seconds and than nothing at all. Can anyone help me?

I had the same problem ( strangely,it occured after a whole night charging, f... knows what happened)
Tried to change charger. No luck. The phone won't even boot by pushing Vol down+ Power
Solution: I simply connected the phone to a portable external charger, and tadaaaa !!! it was brought back to life !
Hope this helps

Help! Battery dead

Hi,
I was given this phone without knowing any history of the problem, (if i get information i will update).
The phone doesn't power on, not even on recovery or download mode (i used these directions: https://thedroidguy.com/fix-galaxy-s8-wont-power-troubleshooting-guide-1079105). Connecting its charger seams to have no effect on the phone.
No led indicator no nothing...
The charger is charging another phone i tried.
Any ideas on how to bring the phone to life again?
Thanx in advance, i know the information is not enough but i expect information update soon.
* Update
The phone had stuck in a boot loop and it left charging for a long time.
Then it was left on battery untill it died out of battery and want power on or charge.
