Good morning all,
I bought a used 5x on eBay which was sole as spares because it had a red charging light, wouldn't turn on and when it did it froze.
Sounds like the dreaded bootloop of death. Awesome, easy fix. £18 and it was mine.
I got the phone and stuck it on to charge, low and behold, red light. Ok, removed the motherboard, in to the oven for a bit.... stick it back in and it powers up enough for me to boot it and allow oem unlock. Brilliant.
But then, it stayed on... for hours, 14 in fact, working perfectly. Then as soon as I plugged the charger in it just stopped working, it became unresponsive, not even a hard reset did anything, no red light, nothing.....
So I repeated the motherboard in the oven and woop woop, it fired up again, no issue.
This time I flashed the latest Oreo build, and the 4 core boot.img on the BLOD thread and it stayed on again, for almost 24 hours. Then it needed a charge so I plugged the charger in and it just froze again....
I'm wondering if there is an issue with the battery, or with the charging port, any thoughts? Or questions?
Thanks guys
did you mean pull yhe plastic body on back, remove the screws ,pullthe joints of camera,speaker and other..then pull another hardware surface..and then i find the whole motherboard and just put it into oven??

Hello people
A couple of hours ago, my phone shut down due to empty battery. I came home, plugged it in and booted it, all was fine. At about 60% I shut it off and went to have lunch, when I came back and tried to turn it on, I couldn't.
Led was orange at the time, I unplugged the power cord but the led stayed on! I removed the battery to be able to reboot it, but when I re-inserted it I still wouldn't boot.
Now no matter how I try to charge it, led stays off like it's not charging. Tried various different cables/chargers, the same. Tried to plug it to the charger without battery but no led flashed. Tried to boot without sim/sd card, still the same.
Any ideas?
My battery has never been changed (for a year now) and has had a bunch of full drains. Could this be a dead battery? :/
Well seems the phone is fried... I tried two more official batteries and no go...
Sorry to hear it. I thought that at first when I read your thread but I thought because I am not the most experienced person here, there might be some kind of fix.
HTC will most likely if not certainly replace this handset for you, seeing as it just happened out of the blue.
Well I certainly hope so, problem is I suspect it's an import (from another European country) and local HTC service generally does not do well with European imports.
Anyway I'll give it a try, meanwhile I'm getting a sensation soon
I have a similar problem.
I'm lucky that my girlfriend has the same handset as I do, the I could compare the phone abnormal behavior tho that of her properly working phone.
The first thing I've noticed, after a while when the charger was attached, was that the phone is very hot and that the battery keeps draining out in a surprisingly high rate.
After a while I've noticed that even when the phone is turned off it wont recharge. Sometimes the Orange LED is on when recharging while it is off, and the LED stays on for a few seconds after removing the charger, as if it was still charging. Note that the affects of connecting the charger to the phone, are mainly the ones listed below (not necessarily altogether)
* The phone indicates as if it recharges.
* Going to an infinite loop of rebooting and crashing.
* Getting hot when power supply is plugged, or at any time when the phone is turned on.
Ultimately the battery was empty, and the only way I had to keep using the phone (mostly to diagnose the symptoms listed here) was to swap the battery with the one of my girlfriend's device, and charge my battery in her device while using her's. That's the place to mention that the battery works just fine and that the phone is draining any battery, no matter what.
I took it apart to have a closer look at the source of all of the heat emitted while the phone is turned on, and it seem to come from the motherboard itself.
That's all I have.
The worst thing is that a friend of mine who helped me opening it up broke the pcb of the volume keys. Now I checked and It turns out that that pcb is actually part of the flex cable, which sort of extension of the motherboard and is mainly the second most important piece of hardware of all the phone parts (not that there are so many). If I would be able to expose the conductors inside the flat cable I might be able to solder an alternative volume pad I'll make out of old some miniature switches I have. The cable is very thin. any Ideas of how to expose the relevant conductors without ripping the cable apart?
Just a (late) update:
It's been almost two years, I had given the phone to a close friend of mine after a couple of weeks since writing the first post, just in case he could resurrect it, nothing.
Then, a couple of months down the road, the phone suddenly woke up! He tried to connect it with the charger, after months of not being able to charge or boot it up and somehow it worked. And it has been working flawlessly ever since.
I just got it back to give to my girlfriend until her sensation is fixed, flashing Viper now
In case something like this happens to any of you, don't give up!
So after nearly 2 years of having my m9, the battery is finally gone in it. Charges last >1 hour, so I just replaced it, since I cant find a newer phone that Id like to take its place.
Everything seems to have gone smoothly, except that when I try to boot it now, the orange LED just blinks on and off a few times, then goes dark again.
I've come across some issues online related to CWM, that supposedly the phone will not take a charge from a completely drained (in this case new, and uncharged) battery, if CWM is installed?
Is this true, and if so, how can I fix it?
EDIT: So I managed to fix it myself, I did have to manually charge the battery. Took the back casing off the phone, unplugged the battery. (did not remove it entirely) Then cut the end off of a USB cable. Striped the red+black wires, and just held them against the pos/neg connectors on the battery for about 5 minutes. This gave it just enough of a charge that the phone would now charge on its own when plugged in.
So, the other day I accidentally dropped my Zenfone. When I picked it up, it had been shut down. I couldn't boot it up anymore after the drop. After like maybe 1 hour I opened the phone up and reattached the battery wire. Then I got it working. But then the problem was that the phone got really hot, even when I wasn't using it.
I waited until the battery was completely dead and then tried to recharge. And now the problem is that the phone won't charge at all. It still gets really hot. When I plug the charging cable in, it just vibrates, shows that it is charging, but then just after 20seconds it stops.
And now I'm asking, what should I do? I also tried to disassemble everything and then assemble everything back again, but with no luck.

inspect motherboard for physical damage with a magnifying glass. go for reflow if no physical damage.
I was browsing the web on my G4 (US991) the other day when the it froze and restarted. I set it down while it was rebooting and came back 5-10 min later to find that the boot screen was still up. After another few minutes absence I returned to find it entirely unresponsive. It does not respond to any attempt to start or reset, no LEDs turn on and nothing appears on the screen when plugged in, and my PC does not recognize any device when it's attached. The only sign that electrons are still moving in it is that the battery will warm slightly when plugged into the charger for an hour or two (this did hot happen at first, perhaps because it was nearly fully charged when it died?).
While I wasn't present to confirm it, it sounds like the phone may have gotten caught in the infamous bootloop. However, its complete unresponsiveness seems to be worse than most cases. I haven't had any battery issues - it holds its charge decently, isn't bloated, and still shows 4V on my basic multimeter.
Should I buy a new battery, bake the board in the oven, or light a candle and christen it a paperweight?

Get a new one. G4s are cheap these days
I plugged in my Zuk Z2(plus) into a charger yesterday happened to be a fast charger QC and within about 10 minutes it went up in smoke charger seems fine (cable melted) but the phone now only shows the ZUK logo and switches off,
Doesn't seem to charge either just vibrates, from the looks the charging ports a bit melted, Was lucky it didn't properly catch fire,
Anyhow to the question, I can get to (stock) recovery and I imagine I'll need a new charging port, but anyone know if the motherboard is likely fried too or would I get away with a new charging port on it ? (and obviously never charge with a QC again) .
I had the same thing happen to me. I was charging my ZUK in another room using a Quick Charge 3.0 charger. I went to check on it. There was smoke coming from the charging port (which was scorching hot) and a horrible electrical smell. Phone wouldn't turn on. From what I remember it was just a white LED when pressing the power button, maybe the vibration too. I tried to charge but it wouldn't do anything. Couldn't boot to EDL mode. I thought it was dead.
A few days later, I remember plugging the phone into my laptop (in another attempt to diagnose the problem) and at some point I got distracted and left it plugged in. After about 30 minutes I was suprised to see that it randomly powered on by itself and came back to life. I believe I still had trouble getting it to charge, and that the battery percentage was stuck on 0% when when plugged into the mains. But eventually it all just fixed itself and I have been using the phone for another 2 years without issue. Guess I got lucky.
Sadly it sounds like your phone is a little more damaged that what mine was. I did not have any visible damage, it was just a bad electrical smell that remained for a few weeks or months. I have heard from other people who had this problem and I believe there is a little component on the motherboard that overheats and burns out when trying to use a Quick Charge mains charger. But the phone works fine without it. I know the charging port is fastened to the motherboard so it would probably require soldering.
Example of replacement - Try looking on other sites like AliExpress: https://www.maxbhi.com/charging-connector-for-lenovo-z2-plus-32gb-zuk-z2.html
Don't I remember people hacking "the fast charging chip" off the board to fix this problem? Literally prying the chip off and it sorting this issue out and allegedly the phone working well. Try a search for something like that.
I know this was a common fault with fast chargers killing the phone.
