After motherbiard and screen swap : no charging ?? - ZTE Axon 7 Mini Questions & Answers

Hello,
I have swaped motherbard and screen on axon 7 mini. In fact, first I replaced screen on my son axon 7 mini. But boit was weird and no correct charging si I thought Iit was my fault at working with naked hands (no gloves cause static electrical shock ?)
So I décidéd to buy à broken device wich have broken screen but good mobo on Ebay.
I kept all from. first phone and only swapped motherbord.
I plugged it for charging but it dont charge. Instead the screen show first thé battery with %0 à lighting and then showed a battery with big réd "X".
I swapped the battery but se problem
Tried to perform à Factory reset but no way. Axon 7 when plugged but immediately turn off
After boot and show à blinking red led.
I notices that battery connexion is very tiny. The connexion is weak but I think I really do the best to insure best connexion.
All of that sounds that battery is not recognized isn't it ?
What should I try ti fix that ?
Thanks in advance for your help

Dead magician...? Red light!

Hi all,
Need som urgent help. The backcover of my device is not fitting well any longer. Guess I´ve bumped it to many times...
As a result (Iguess) I cant turn on or even charge my magician!
The only thing that is happening when I try to charge is that a red light is turned on. What does this mean?
Any solution of how to get it work again?
Is it possible to buy a new back-cover? Live in Sweden.
Thankful for some ideas!
Regards Emil
Most probably the notch on the battery cover that hits the microswitch lever has broken. You will find the microswitch on the lower-right corner of the device when facing down. Put something soft but strong enough (ie. foam) to keep the microswitch in the ON postion then mount the battery cover and temporarily fix it with tape. Be sure to keep your device plugged in via USB or charger in order not to totally discharge the backup battery. If the backup battery gets depleated, then it's like doing a hard reset.
You can buy parts from ebay but I've always bought from Brando and is very reliable dealer (shop.brando.com.hk). Delivery is quite fast too.
Hi Zerimar and thanks for your answer!
Unfortunately that didn´t do the trick. Still the same red light when trying to charge. And I can´t turn it on! I am pretty sure that the battery is flat out by now but even so I would think it would load and then after a while, I would be able to turn it on.
Am really frustrated abt this!
Any more ideas maybe?!?
Regards Emil
u'd better send it to service...

Well, that´s what I´m trying to get around... Thats why I´m hanging around here
If have have my device charged via USB or charger, the LED becomes as soon as I remove the battery cover. If I hit the microswitch lever then the LED turns green and start to boot up. If main battery is removed the LED stays red even though hitting the microswitch's lever.
It looks like it's not charging your main battery or your battery is already defective. If your device is over a year old and you're still using the same battery, then its time to change it. Bulges in a battery is a sign that it needs replacement.
Before sending your device for repair, why not look for someone you know who also has a Magician or equivalent device and quickly borrow his/her battery?
I had red LED when plugging into a main charger - and then the phone reset.
Red LED + loop booting-poweroff = dead battery
If the LED is RED when you charge your device for hours
If the device tries to boot sometimes, but powers off by itself some minutes after (it means, at least, that your device CAN boot! )
Your battery may be dead, I bought a new one for 10Euros on ebay...
Those batteries are perfectly compatible with HTC Prophet or HTC Beetles (Ipaq 6515) and maybe other devices... easy to find!

Notification LED red.....MDA dead

Help....seems that my Magician is dead....making a long phone call (1 h) after call end, display switch off and Notification led become fix Blue (bluethoot was off) and then i try to hard reset. Led switch off and no results. I try then to put the power supply cable and the led become RED.... !!! (neve seen red.....) pda is not switching on anymore...any details on the reason of this RED light ???....please.....
thanks in advance
Red LED means the battery isn't connected or the device can't charge.
Try taking the battery out for a few hours and try to switch the device on again.
My brother in-law had the red LED issue too, we solved it by 'kick starting' the battery with two wires and a 9v battery. (At your own risk of course).
Good luck!

Red Led doesn't mean that the battery is not connect with the device. It simply means the cover is not properly intact. Try taking out the battery off the device, put it back in the slot. Place the cover carefully and completely. And then connect the device to AC power supply. It would definitely come *alive*
still dead....grrrr
so cover is ok...it seems to be properly fixed, even the smal swithch that create some unwanted crash few months ago is now working properly...
i made a 1 h long phone call with battery and charger (usb from pc) and after line felt down, bluetooth led blue on (was off) and screen with phone but no changement by touching it. so switch off by power off and ...dead...now without battery but with charger (or usb from PC) RED led on. With batttery AND charger RED on, and with battery all dead. i cannot reset anyhow with or without battery /charger....need it...sh*t.....(ops...sorry)
thanks a lot anyway....

what I will suggest is, you should get a new battery instead!!
Got the same problem now!
Both my wife and me got a Magician. Hers is dead now - same symptoms.
First guess was dead battery as well. But I exchanged it with mine fully loaded. No difference!
Usually when you plug the powercord into the device orange flashes up and device boots. Here nothing happens.
I'll have some electrician have a look at both. Maybe he can find the fault by comparison. But I don't expect a lucky outcome.
on back side of ur device when u remove the battery cover, u see a small black switch on the right side just next to the battery.
put the device on charge..with cover off---it will show red light contunuously on.
now manually press gently that black switch and see if ur device starts to charge.
if u see a yellow light any point of time doing this u may have to get this little switch repaired or do a temporary work urself by kepping it at place manually bu something.
try and tell
Now it works!
I think we all knew about that little switch. But thanks for your thoughts.
Anyway, hers is running again!
Two days ago I took it fully apart. No obvious fault noticeable. I left it the way it was now to prepare it for shipping. Today my wife asked me I should try it just once again. So I held the battery on the connector and plugged the USB cable and then: it booted!
But the internal battery doesn't seem to recover. It stays at 0% (1h "charging" since then).
I have to correct myself: Even the internal battery is charging (but it takes its time).
my magician is also dead and just the red LED is burning when i put it in the USB! Can anybody help me?
Still ned solution!
Can some one who was having the same problem help?
your device battery detector switch(little switch) is broken or logged-out of Main Board.
when it broken,the red LED is on at all.
it is the greatest weakness of magician...

HD2 dead?

Hello,
please help me with an advice: since today afternoon, my HD2 (European type) looks dead... I have an Android NAND ROM (with sense, I think from CM7 series, but I don't remember anymore, cause it worked perfectly since a few months). Suddendly, as I wanted to recharge the battery today afternoon, I've observed that the LED indicating the charging is not on! As I've tried to turn it on (wake up), nothing happened, black screen, no LED, no buttons light. I have put out the battery and back in, tried a reset (red small button near the battery), but it simply don't want to turn on! I have checked the charger with another HD2 from a friend and the charger is ok... What can I do about it? I have really no idea what's going on , cause there is no reason for such a behaviour (like bad flashing trial or similar).
Thank you in advance for every help!
Conrad
...nobody?
I want to add that if I connect it with my pc through the usb cable, nothing happens as well... and my pc won't recognize it (no reaction at all)...
Please, nobody else had such problems?
Your friend has hd2? Try their battery, if it works your battery is flat (can't charge when off when magldr installed)
If the other battery doesn't work check battery pins carefully.
Thanks for your reply, samsamuel.
I have already tried to use other battery, but it doesn't change anything. What do you mean with "checking pins"? The battery contacts, on the battery and on phone are looking very good (the phone is only about 7 months old)...
Sometimes one of the three little pegs on the phone that the battery presses against gets bent.
What about your battery in friends phone?
Other than flat battery or bent pins I can't think of anything else except something serious blew on the mainboard.
The battery works well in my friend's phone (has about 48% capacity). I have also tried his battery in my phone, with no success.
How can occure such a major hardware problem, without any reason?
Sorry, no clue. Random hardware failure? Crash causing hang and overheat? Someone messing with it whilst out of the room? Power surge? Got warranty?

[Q] Weird battery/charge problem

Recently my Omnia 7 has a problem with charging and extremly quick battery degradation.
After charging the battery the battery icon keeps showing the charge icon.
When the battery is at 50% a constant alarm is ringing and the battery discharges itself very fast.
http://www.youtube.com/watch?v=vOz-jORsJVk
Maybe it's the battery but why does the battery icon stays on charging?
Hello,
I've got the EXACT same issue!! My Omnia 7 starts to beep and chime at 50% and won't shut up! And the battery starts to drain really fast..this all started happening after the last update I did..and now my computer won't even recognize the phone it just shows up as unknown device and I can't do any further updates.
I went back from OS:7.10.7740.16 to OS:7.10.7720.68
That did not solve the problem.
Bought new battery but the phone shuts down after 20 seconds with the new battery...
(on or off charger)
chicagodesi786 is your battery icon also indicating charging all the time?
I think it's a hardware problem. (probably the USB cable socket)
Whilst this hasn't happened to me...
My sister's Omnia 7 has done this. Although a battery pull shut it up for her and it's been ok since.
Hello,
I've done the battery pull trick, but it still does it from time to time.
I think it's the USB cable socket.
I lost connection to zune and fiddeling with the cable made the phone connect again.
I send the phone back to Germany for repair.
Will post the outcome here.
Problem solved
It's an electrical interference at your micro-usb. What you need to do is to separate the metal part in the center from the metal part at the outside of the usb port. I used a small screwdriver to force it!
Wow Quadcore it seems that you are right! +1
I send the Omnia to Germany (w-support.com) for repair and they refused to repair because of "water damage" .
Totally bogus, I never exposed my Omnia to any liquid. ("waterdamage sticker" = a oke)
TIP: make sure you take a picture of your "water damage sticker" before sending your phone in for repair!
Just today I read your reply and seperated the 2 sides of the USB socket.
Omnia is working without beep beep or extreem battery drain.
I did send samsung.de an email to demand fixing or replacing my Omnia.
The problem is still there.
Bending the usb port helps for a while but the problem returns.
not sure if helps:

I'm trying it right now.
Did not work Omnia started beeping when i took it off the charger.
Finally the Omnia is back from repair.
Motherboard is replaced.
Because of that my back-ups can't be restored.
All works fine now except I can't install update 7740.
I get the 80180048 error.
All the phone information is the the same only the Radio hardware version changed from 0.0.0.2 to 0.0.0.1

[Q] LG G2 Red Light No Power

Hi All
My friend recently gave me his LG G2 as it had a problem.
What happens is currently if you try and turn on the phone nothing happens. When you plug the phone into the charger the red led blinks and nothing else happens. He told me that he got the phone brand new off eBay and that the problem started after he left the phone plugged in overnight. No software modifications have been done to the phone prior to the red light issue.
After some investigation into the issue i found nothing except another eBay listing with a LG G2 D802 where the guy got water into his phone and it has the exact problem where the phone does not turn on and a red light comes on when attempting to charge the phone. The eBay listing also says that the phone was seen by a service technician who said the circuit board was damaged but is repairable
Before i spend any money buying spare parts does anyone have any idea on what the problem is and whether its worth fixing?
Thanks
Could it be that the motherboard got damaged?
I don't think the mother board got damaged. I had the same problem with both my G2's. (D800 and LS980)
I had changed the motherboard from ls980 to the d800, I connect everything, LCD, digitizer, battery,front and back camera ..etc..
I go to try and power the phone up but nothing happens..
I go to plug in the phone.(Nothing happens)
I use another charger(nothing happens.)
My phone wasn't water damaged though. In your case you could open up your phone and disconnect the battery connector, After about 1-3 minutes connect it back & leave phone alone.(don't try to power up)
I had a problem with one of the phones not having the red LED light coming up to tell nevit was charging. I switch the battery to another bezel & motherboard & it shows 40% battery level.
It definitely worth a try to open your phone & disconnect and connect the battery if the phone was charging one night.. I remember seeing a forum on here that the phone might be still on charging mode or something.

Hi,
I have the same problem, the only sign of life is a red flashing led when I try to charge it up.
My lg g2 (D802) did get water damaged tho, however I don't think it has been damaged that bad. When I found it in the watery environment it still worked, but it was quite warm. First hour or so I put in in a towel, because I wasnt home. When I got home I discovered it was dead. Then I put it in rice for two days, but now this problem occurred.
I reconnected the battery (twice) but it didnt change a thing, and now it still won't boot up...
Hopefully someone can help me (or sees this at all),
Thanks in advance
I have the same problem with my G2. I changed the motherboard after it got water damage but nothing else changed. what should i do?
Solution for blinking red error
Hello Guys,
I have the same problem like you others. 8 times red blinks, phone won't charge, PC won't recognize it, dead at all. But I found the solution. There is a short circuit on the moterboard. That can be LCD, digitizer, buttons or anything other. I have unpluged digitizer connector and BOoM!, connected it to charger and turn on with power button. So you guys can test what's making problem on your MB, it can be anythinhg. I hope that will help to someone.
Sorry for bad English.
same thing here
I have an LG G2 that I recently replaced the batter (ordered from ebay). After the install, the phone just blinks the red indicator light. When I hold the power button, it blinks 8 times, pauses then starts over again blinking 8 times and pausing. Please help.

I'm having the exact same problem...working ls980 phone using to restore my D801 motherboard....but have no power.
When I plug the ls980 board back in it works again. Last time my D801 board red led blinked 2x but wouldn't startup with its own battery. How did you fix it?
It is the battery. either the cable is ripped or the battery is at 0 volts I've just tested this on my LS980 using my analyzer to fully charge a battery externally to 100% made it work fine, please check the battery cable its very thin and very easy to rip without knowing it. (I work at a battery store) Hope this helps some of you!
A solution for 8 Red blinks:
If you have 8 Red blinks when you change the screen the Solution is:
The two metal joints from two small boards (besides volume and power button) that connect to the motherboard they should be completely attached to the connector.
