Hi,
a couple of days ago my ASUS ZenFone 2 (Z00AD, ZE551ML, 4 GB RAM, 8 GB ROM, 1.8 GHz) started behaving very erratically on its own. It's not been rooted nor has been the bootloader/recovery modified.
OS version was the latest: WW-4.21.40.352.
Before it all happened, I cracked my screen and replaced it.
The phone worked perfecty (aside from the screen not being original (occasional flicker)) for a week, after which I started to lose signal in the SIM1 slot. It took me 6 weeks to realize, it might've been the antenna cable. I disassembled the phone again and inserted the cable again. It then worked perfectly for a couple of days.
Then it looked like it was damaged by water, which of course was not the case.
It started with continuous vibration and black screen, and only a forced shutdown (by holding the power button for a couple of seconds) helped. Then, it started to restart on its own and lose signal. Then the speaker stopped working, until poking its area. And at last, the phone thouht I have View Flip Cover on and all I could do was to force shutdown.
Then the phone didn't wan't to turn on at all. It didn't even charge and was not being detected by the computer.
I then read, one has to pull the battery cable twice and it did help.
The phone worked fine for a day, until it started going into black screen/constant vibration state, in which only a forced shutdown helped.
I followed a guide to redo hard brick and it's helped for a while, but now the phone constantly goes into black screen/constant vibration state at random, the same hapenning sometimes when charging while turned off or when choosing any option in the stock bootloader. It also doesn't boot completely (the ASUS logo shows up much later) and the WLAN doesn't work.
I followed the unbrick guide correctly. I read up, the mainboard might be corrupt.
What do you suggest? I of course, lost my guarantee the moment I cracked my screen.
Many thanks in advance.
Check the connection of the flex cable on the daughter board. Pretty sure there is loose connection.

Had to shelf my phone for a year because of this. Gotta clean the connector and press the cable in there good.

Hi there
I recently attempted to change the digitizer on my one x, breaking the lcd in the process.
I ordered one from eBay and installed it along with my new digitizer. Both went well and my one x was looking fresh again.
With the housing off still, I wasnt 100% happy with the double sided tape i used so decided to redo the bonding process.
Anyways... Long story short.
My wife accidentally spilled the tiniest bit of water on the surface my phone was on. It did get on the phone but not too much, I broke down the components and put them in a rice bag overnight. now the lcd screen is cloudy (not a problem really, can get another for £20) but the htc logo comes on with a vibration as normal but then after 3 seconds goes off and repeats. Thinking my battery could be drained I've had it on charge for at least half hour with no luck.
I hope this isn't a hardware issue. I can't afford this right now.
Trying to boot into recovery brings up the low battery text too but again reboots after 3 seconds. Ive triple checked all ribbons/cables/connections and everything seems fine.
Any help would be appreciated. Many thanks
Edit: A post on this thread... http://androidforums.com/htc-one-x-xl/635327-help-my-htc-one-x-wont-stop-rebooting.html hints at it possibly being an issue with the powerflex cable attached to the power button. After a few wiggles and playabouts the phone went on to the bootanimation but then rebooted. So its possible it is the cable?! How do i go about changing this and further testing to make sure it is exactly this?
Edit II: Seems to be now the powerflex cable is faulty, as when I disconnect it from the slot, the charge LED now remains constant. I've disconnected everything else. Leaving it to charge for a while then gonna research the power cable. tried connecting the power cable but it just causes it to restart with LED flashing every 3 secs. hence why i know it restarts.

you should be happy atleast your motherboard is okay now try getting a new power flex cable and check whether your htc still reboots or not with the new one,,,best ov luck :good:
Cheers mate. One is on order from eBay. I ended up removing the power cable because it just interfered with boot ups. It's a bugger having to use sweep to wake and ADB commands but at least it now works
Also no mic for calls but that's OK. Loudspeaker works still

those are minor parts you can change them well congrats um happy for your reborn HTC ONE X :good::highfive:
Hi guys. I just got a flex power cable yesterday, and I installed it onto my gnex, but I still have charging issues (Boot up, 2-3 charge up cycle animation, reboot up, 2-3 animations again, rinse and repeat).
Could it be a problem with the back cover?
I also switched out the battery for an OEM one, and the phone is still acting like a jerk.
The thing is, when I pull out the usb cable, the phone still thinks it's charging for like 2-3 seconds before it turns off.
Could it be some random internal capacitors gone to sh1t?
I really REALLY want to solve this because I am not ready to ditch my gnex.
no one has a solution?
This phone forum seems to be dying.
Edit: try a factory reset. Use the stock recovery by holding the power and volume up and volume down if you can't get to your settings the normal way
I was facing the same problem until I moved the micro usb pin towards a bit to the screen using a very small screwdriver. you can try that once. but do that very gently so that it doesn't break. you can use a small plastic pin/toothpick also.
so far, its working fine for me.
I have the same problem and I have just tried this without any solution!!
I tried pushing the pin forward towards the screen. It doesn't work. Do I have to push harder?
Hi,
I hadthe same problem where no cables i tried worked..
I had to send mine in for service to change the pcb for my usb-port. it did the trick for 6 months time. nice phone, but ****ty usb contact..
hope it helps..
Hey, I really need some desperate help.
So I have a Canadian Note 2, SGH-I317.
It has no SIM card inside it, and it is just connected to wifi.
I have flashed 2 Custom ROMS before on this phone.
The first one, was a 4.4.2 Homemade t0lte ROM.
It worked fine for about a week, but then I started to have this big problem.
After I plugged in my friends charger at her house, (a Samsung Note tablet charger) then this problem started shortly after I left her house:
When I leave the phone alone, it will go to sleep automatically like every other phone. Then, when I press any button which wakes the phone, the touch screen is unresponsive, and the phone since no input is coming in, goes back to sleep and doesn't turn on again until after a while, where it will boot back on itself and start working until randomly out of chance (chance meaning atleast once every 1 - 4 hours) it will do the same thing again. It's getting really annoying and starting to be destructive, as it stops important conversations and other stuff.
I initially thought it was the homemade ROM.
So, I changed the ROM. Now I'm using a better one, and it's called W03 Slim v9 t0lte, and it's 4.4.2 and works good.
I was not seeing any problems up until a few hours after the install of the new ROM, and the problem which I thought had been removed was still persistent. Now, its even more often than the old homemade ROM. Just before posting this, it has happened twice in the matter of 1 hour, and it's just getting on my final nerve.
I'm not sure if this is a key factor, but after it goes to sleep, I still see the visible white pixels of the 4.4.2 shutoff effect.
My final thoughts are that it might be the battery, but I have no idea how to get a replacement for that, and how much they cost.
Obviously I can't send it in because the warranty was voided when I flashed the custom ROM.
I really need a solution, and ultimately I could wipe everything and go back to the stock ROM, but that, in my scenario would be a last case scenario.
Thanks, Delbert.
NOTE: Just found out that when I turn it on, and the touch screen is unresponsive, the S pen works with the phone, and the back and menu button doesn't work. But, all physical buttons do. The physical home button works, but all the rest except the S pen works. So I can navigate the phone unless it goes into sleep mode, in that case no matter what I press, nothing will make it come up unless it reboots.

your friend's charger could've damaged your phone
i've had a charger that made my touchscreen unresponsive while plugged in... thankfully it didn't do any noticeable permanent damage
all USB chargers are not created equally:

Thank you for your reply, but if the charger did do damage to my phone, how would it and how does the touchscreen still work with the S pen?
Is there any way to fix this, and if not what do I do?
I have an HTC One X I could use as a backup, but I would like to install a 4.4.2 ROM on it, and with what I've found out I have to root it, which requires a recovery, which recovers an unlock or S-OFF, and when trying to do that, the phone won't connect via USB to my computer. I am frustrated but at the same time sad.
Should I just factory reset my whole phone and erase everything?
I had my H815 repaired (main board ) just a few weeks ago. But I lifted it to read a text message earlier and the screen was blank. I thought it maybe needed charging but when I connected the charger it made the connected sound and the charging led came on. I forced a power off and powered it up again. It played the startup music but the screen remained blank. I've tried restarting it several times but although the backlight comes on, there's still no picture.
Can anyone suggest what I can do here rather than sending the phone back to LG again? They're pretty fast with repairs, less than a week for my previous one, but I'd much rather fix it myself if I could. Is it possible a connector has popped off inside or something?

This might seem hard to believe, or maybe it won't, but I lifted the phone last night when going to bed and the screen just started working again. Usually when a complex electronic device stops working it stays not working until it is repaired. But it is still working away without so much as a flicker. I'm totally flummoxed, to be honest.
Then it sounds like a loose connector cable. if it happens again, myself would disassemble it and check and make sure all the ribbons are seated firmly.

Hi,
One of my friends G4 has weird issue...When he switches it on, it starts very normal but freezes after couple of minutes of normal use and only battery pull work to restart.. (Phone do not heat..)
"Strangest part is"...if he connects it to computer or wall charger then he can use it normally...No hangs, no heating and no restart...he tested it like this for several hours even through the night once...without any issue and he still uses it occasionally while connected to power.. (When he removes the usb power, display freezes immediately..)
Any Clue..?.
He tried battery replacement...didn't work..
Swapped display with other G4..same issue.
Any help is highly appreciated...Thanks.
Edit: Model: H818N DS
Tried LP, MM firmwares but same result, currently on Nougat by SezerSimsek
Is there a chances if it is bad USB port or else...?

The g4 is so riddled with issues hardware wise it's hard to tell. I would recommend another battery

I gave him a tip yesterday to check if it works by connecting OTG and received a call a while ago as below..
Phone working fine by keeping only OTG adapter in usb port..
How to explain this.. USB Port to be changed..?
Update:
USB port changed but same behavior..I noticed that phone works fine even keeping only usb cable in phone while other end is not connected to power source...never heard of any issue like this in G4/phone..

You can't use the h818 display on other models and vice versa. H818 is special due to double sim and has an own lcd.

Hi,
I have been following guide by wit rigs to replace my rear camera due to focus issue. I had ordered correct tools from their website and started following the steps.
https://www.youtube.com/watch?v=k76StG0DaZ0
1. opened the phone's back, removed screws, opened motherbaord, replaced camera, put back motherboard and connected it all.
After all those steps, I booted the phone to check the camera. It worker perfectly fine with proper focus. Now, I put few screws on.
I thought I will try again and verify before I put back the back and close everything. But to my shock, phone is not booting when pressed power key.
I checked all connection 2-3 times and tried again. Thinking that some of the battery related connection may be not done properly. But still no luck.
Any pointers/suggestions?
Thanks a ton in advance.
by the way, I started with 75% battery. Not sure if that is the issue but is it advised to connect charger while back is open and see if charging light comes on?
Potential short? Also look for loose connections/maybe some connections became unplugged.
Check the battery connection (motherboard to battery)

Check whether the connection of battery is connected properly or not as it a switch like pin press it until a small sound appears....

Thanks everyone for the help. I tried doing assembly multiple times and nothing helped. I also checked power and battery connection. Nothing worked.
Finally, I lost the hope and decided to assemble everything back and give it to customer care. So I did just that. Assembled back everything and put the phone aside.
After assembling I reconnected charger to see if charging is working. To my pleasant surprise, charging animation came up and then reboot also went fine.
Now, I don't know whether issue was resolved due to last assembly or due to connecting the charger. But my phone is working fine now. I checked all hardware components and everything is working fine. My new camera is working perfectly as well.

It didn't work before, because the power flex connects to the mobo via pins, so it has to be pushed down and be in the right place, so each pin connects to the right plate.
