The phone was normally charging in the car charger (my fault?), The moment the auxiliary cable was removed it went into a kind of a bootloop and after it was taken out of the charging it went to a white "Bite dog" screen with a few small words. On that screen it said to either connect on a usb cable to do something with the ram or press volume down to restart normally, but then pressing volulme down it would return to the same screen. Connected to the original charger it started a bootloop cycle again, so to avoid damage as it was too hot it was let it discharge. And afteer that nothing else appears on the screen, even connected to the charger and it gives no response, even with softreset or powerup buttons.
So I send it to the maintenance service, and they solve the problem relating the following issues and solutions:
Symptom code: MDGC - Automatic turn-off
Defect code: MGCP - Software uptade
Solution code: F05 - Software uptade
Is something that I could solve in home. And any chance if I put in my car charge this will happen again?

Hi All,
I have a strange problem I wish to share (don't worry its with my Charmer !)
I am not sure when it started occuring, but now it will only boot with the USB connected. Without it I get a hangup on the 'Wondows Mobile' blue screen. Connect the USB and the version numbers on the T-Mobile boot screen come up much quicker and then after about 1 minute of the Windows blue screen it is on.
It is really weird ?
The onlys changes I have made is the registry memory improvements (mentioned in this forum) to try and get a little extra speed. I am pretty sure it did not start immediately after that though.
I was wondering if anyone else has encountered this
and if so
how did you overcome the problem.
Thanks.
yes, it is weird.
what you can do is
(1) see if it is battery. try connect it to your charger to see it boots up. If so, maybe it is a batteyr/power problem
(2) check if it is what you've done - back up (using any software) and hardreset your device. if you device is not able to boot up after hardreset, it is a hardware fault, have it serviced
Guys, I have the same problem with Time & date backup when change main battery but with more sympthoms:
Aprox. 1 month of using my XDA mini S (original O2 UK ROM) I faced to problem which seems to be HW status.
I didnt not change WM5, I did not change ROM and no new soft has been installed during last month. I have no backup manager like SPBackup or
Backup manager installed on miniSD card (or in main memory) and no backup process is planned in Today screen.
PROBLEM:
It is not possible to boot Windows Mobile after soft reset WITHOUT ORIGINAL wall charger. It does not matter if I make soft reset 5x-10times, PDA frozen on
WM5 booting logo and keeps like that for hours with backlight ON.
Neither USB-PC cable connections nor other charger (from GPS receiver 500mAh) does not help to boot WM5.
I found out, even if PDA is POWER off (Power button press for more than 3sek) and I want to turn it on, PDA freezes on Windows Mobile window.
I got answer from one hungarian service point like:
"We know the symptom that you described below. Solution for that is a software update. Unfortunately there is a built in protection in upgrading package and we can not update phone software of other country's phone."
MY SOLUTIONS:
I doubt about correct solution from service because:
I make a miniUSB cable (like for charger) and connect other main battery to this cable. When second battery is connetted instead of original charger, XDA mini S boots and restarts correctly without freezing on WM screen.
I tried to to test how original backup baterry (in fact capacitor) works - parameters in Service manual at page 81 (CG1, Gold cap, 0,07F, 70 Ohm, 3.3V, Part number 16H00012-00M).
The I connect a capacitor 3.3V, 0.02F to this USB cable. I charge a capacitor externally and try to restart device with capacitor connected on USB cable (now without 2nd battery). Everything was OK.
Then I completely discharge externall capacitor and interesting was, that device can boots up correctly even with discharded capacitor because during booting, capacitor has a time (maybe 5-15s) to recharge.
CONCLUSION:
I think the backup capacitor (Part number 16H00012-00M) is damaged.
Do you know idea where to buy it on web (the best in Central Europe for me)?
Now with external capacitor on miniUSB cable in my pocket, it allows me to make soft reset or reset if device freeze anywhere at the street without 240V original charger. "What a Soviet solution ;-)". BUT WORKS! ;-)
When turning on my trinity, I have the welcome screen "running" up and having a white stripe in the middle, well just look at the picture.
I just cant turn on my trinity.
If somone have idea how to fix this, please.
thanks in advance.
I'm having the exact same problem for weeks now!!
The first thing i tried was removing the sd card, and replacing the battery,
this seems to fix the problem for a small period of time (up to 1 day).
Don't be fooled, the problem will return when you need your phone the most
Reflashing the device with the same/different ROM has no effect!
Being an electronics engineer, i carefully checked all the connectors inside the screen, and everything is connected as it should be..
If anyone has any suggestions.... ?
Sjerby, one thing you can try to temporary revive your phone is this:
-Remove the back cover and take out the battery
-Plug in the charger, do NOT use the usb cable!!
-Put the battery back in, but don't try to power on the phone
-Leave the phone to charge for at least 20-30min
-Power it back on. You might have to push the power button twice for it to respond.
My findings are that the device somehow uses more power than the battery can
supply, but using a brand new fully charged original battery does not fix the problem!
ummm... the phone DOES work once in a while but it get stuck fast after, somtimes it just show's a black screen.
and i have no charger i use usb cable to charge it, i forgot the charger in a vecation ><
and just for the record the camera is having problems aswell if it makes to turn on
My i9000 has been working fine and I have flashed it countless times but now I can't switch it on using the on button when I don't have it plugged in to a power source!
The behaviour, when no USB is connected is a loop: The moment I put the battery in, it starts up with the "Just about to start charging" egg timer (more a circle/flower icon) - then an empty battery appears for 2 seconds. Then disappears again and the whole process starts again 5 seconds later. The only thing I can do to interrupt this loop without a USB cable is to enter download mode using the 3 button combo - recovery mode combo doesn't work.
I can interrupt it by plugging in a USB cable which seems to act normal (charging) then the phone acts like normal...
Anyone got any ideas?
Since the phone is off I really can't imagine this is a software problem (unless someone knows differently).
I would swap the battery, see if it has gone bad. If not, then it must be a hardware problem either with the battery pickups, the USB connector, the power button or the charging circuitry. Lots of possibilities, but all with the same solution...return for hardware repair
You can try to clean the battery pickups and USB connection with a little acetone on a q-tip, see if that helps, but this sounds like it will have to go back to a service center.
I advise u to change the phone in guarantee as fast as possible, I managed to kill just like this an SGS, a small diode makes the problem and ordinary services don't have this, Network broadcasters (Orange , Voda) changes the whole m.b.
Firsty u can flash a stock 2.1 from samfirmwares.com - (to try repairing and to avoid losing guarantee) )
Thanks guys - will return it to the shop I bought it from when I return to the UK soon.
After installing the 5.0.1 patch last night, I find myself in a very weird situation with my Nexus 10. Essentially, I can't get it to display anything, or react to any keypresses unless it is being powered via the POGO plug.
When powered with the POGO plug and connected to a computer via USB, I was able to use fastboot to attempt to reflash the 5.0.1 factory image -- however, the screen remained blank the entire time and wasn't backlit. I was able to get the factory image flashed successfully according to fastboot but when it was complete and fastboot said the device was rebooting, nothing happened. I then unplugged the USB cable and POGO cable, and attempted to power it on and got nothing. Despite how long I hold the power buttons, I can't boot into the bootloader or get any response from the device.
If I plug it in via USB, I get nothing -- no charging icons, Windows does not recognize the device is detected and I still don't have any response from the keys. If I remove USB and use the POGO cord, the N10 turns on with the Full Battery/Lightning Bolt icon -- once here, I can hold the power button for 10 seconds and get it to act like it's going to boot but then the only thing the display will do is flash the white Google logo, flicker very briefly, and then immediately power down.
I have tried several different factory images, all with the same results. I'm not sure what could be the problem, as I think I've covered most all my bases. The tablet was never dropped or water damaged and wasn't exhibiting any signs out of the ordinary until last night when 5.0.1 was applied.
Could this ultimately be a battery issue? I did pull the back off and meter the red/black wires of the battery which read 3.85 (the battery is labeled as 3.77 so I'm assuming this is a valid range) so it seems as if it's charged which is what has me so stumped.
If anybody has any insight on what this might be caused from, or things I can try I am open to any and all suggestions! This one really has me determined to solve it!! Thanks for any and all input!
I don't have an answer for you but you can remove the pogo plug from the equation as it is for power only. To the best of my knowledge Google never added the circuitry nor the kernel code to use the pogo plug for software updates.

Hello,
My yotaphone had some big issues after I've changed earpiece, the actual situation is:
- With plugged battery phone is completely dead, nothing happen pressing the keys and the pc recognize it as an usb input device (no adb/fastboot support)
- If I disconnect the battery connector and then plug in the charger, phone starts a bootloop "powered by android", BUT if I plug in battery DURING bootloop the phone boots correctly to the system but battery is 0% (I bought a new battery and I'm sure that there's some charge stored) and if I disconnect charger it says battery low and tuns off
- I've noticed that if I put phone in download mode>connect battery and then disconnect charger, phone stays on and it happens also during "optimizing apps" step during the first boot after update.
Now, I'm not sure of that but I think that it's an hardware issue (like the "daemon" that reads battery amperage doesn't work anymore) but I need your help tho confirm this supposition and even some things to try before throwing away my beloved yotaphone 2
p.s. sorry for my english
My YP2 has had problems with QI-Charging and random reboots since two weeks, maybe from falling down..
Two days ago, the YP2 got very hot, the battery has blowed and the YP2 was in bootloop.
After changing the battery, the YP2 will run like new again.
problem identified!
Finally I've discovered what's wrong:
battery connector is partially broken and the central contact doesn't touch battery terminal.
anyone have an idea if I can find this connector or if I have no chances to find it?
