Asus Zenfone 2 ZE551ML - very slow charging, not detected by PC. - ZenFone 2 Q&A, Help & Troubleshooting

I have two pieces of ZF2 ZE551ML at home. One is my and the other one belongs to my wife. My wife's phone had a broken mini USB port - the first 2 pins from the left were visible - the plastic had broken apart. Firstly, I did not relaise it could be the problem, luckily I managed to change the whole PCB including the broken USB port, however after this change the phone is not being detected by a PC, nor it is fast charging. As I have two phones at home, I checked performance with the other unit and unfortunately, the other one does quick charge and is detected by aPC, so it is not the cable, neither is it the missing software.
I bought another PCB and changed it as well, however still no joy. Does anyone have any brilliant idea how to fix it. I should also say that all other or most of the functions of the phone are working fine (at least those I managed to check: GPS, Wi-Fi, GSM+dual SIM, torch, bluetooth, and so on).
The only problem is that the phone loops on the SMMI Test #1 and is not going any further. I have also tried to detect phone by adb, still no joy. The phone is not rooted!
I have my personal suspects that it could be the faulty main board or a software bug. Any ideas how to fix it?
My phone is running LP 5.0, soft: LRX21V.WW-ASUS_Z00A-2.20.40.198_20160930_8756_user044030427_201501060109, kernel [email protected] #1 Fri Sept 30 15:31>23 CST 2016

Sdcard slot is working?
I would check the connections on both ends of the flex cable with the sim and sd slots on it.
I am having the same problems (because of the busted sd slot). I ordered a new flex cable. When it arrives (approx. 2 weeks) I'll know if that was the cause.

Yes, SD slot is working and both SIMs, so the phone itself works fine, only very long charging and is not detected by a PC.

may be the pcb you changed is for different version. try replacing it with your other phone if you have the same model. post if works.

Hi, I did changed both PCBs between phones. Firstly, I had the same problem on both phones, then I made better connections and the batteries started to warm up. Finally, the new one works with the other phone, the old one from the other phone still creates the problem. Probably, it is not the PCB then, or USB connection. It must be something else.
Anyone, any idea?

try fashing raw firmware
on motherboard you can inspect or clean the connector where pcb connects. use magnifying glass to inspect connector

Ok, I actually would like to flash the raw firmware, however I need some guidance here, as the phone that has a problem, is not rooted, and it cannot be detected by any PC now, so I am stuck in the middle and do not know how to proceed...

i am little confused here... you changed pcb on one mobile and fast charger do not works on that. you have other mobile which is working perfectly. both are same model.... if right!! do the following thing to find out...
Phone A:- changed PCB. no fast charge, not detected by pc.
Phone B:- working perfectly normal..
now we want to guess if pcb is faulty or there is issue with flex cable or any software related issue..
remove motherboard from phone A. and install it in Phone B.. if on Phone B. things works well then definitely its problem related to pcb.. if things don't works on phone B too. then it may be a firmware related problem..
raw cannot be installed without pc..... the thing you can ty is updating firmware from sd card via recovery mode.

That is correct, I say it again - I have two phones, same model, same software, kernel, etc. One had a damaged mini USB port, so I purchased 2 PCBs which have mini USB port souldered onto them. I bought them twice, as I was not sure if the first one I got was the correct one. Now, after your first message I changed the PCBs between phones and the result is the same, phone A (which is ok) works with the replacement PCB, and the PCB from working phone still does not work with phone B (the one that has a problem).
As a second step I replaced motherboards between phones now, and the result is still the same, meaning the motherboard from phone B does not seem to work better while it is in phone A body. The symptoms I'm struggling with are: charging takes over 8-9 hours, so it is considerably extended charging (battery is original factory battery 3000 mAh), the phone does not fastcharge at all and it is not detected by any PC.
The phone is not roooted so, I'm afraid I cannot make any changes to firmware through recovery, as it needs to be connected by a cable to a PC, unless there is something else I can do about it, but how to get any further?

Is your ext. sd being seen in file manager ?
Can you get into 6.0 recovery ?
If yes , you can now downgrade which will reset your fone , With a factory reset in the process , check my signature below.
Your fone not being seen maybe driver issue if other zens too are not being seen...but ..let's see what happens after downgrade.
After downgrade if still slow charge, reboot while connected to charger.
If same prob ..hardware !

Thanks, I was not so deeply checking all available options. SD downgrading worked well for me, however the problem still is in the phone. However, I discovered a few positive and negative signs, which tell me that there is something else - could be the connection - after upgrading to MM before the phone was restarted at least 3-4 times the screen was not going to sleep mode after a minute, it was coming back on and on and on again. After 3-4 restarts it behaved normally again. The same thing happened after downgrade to L.
Another positive discovery is that the SMMI test now works well and everything is ok now, before it got stuck on the 1st or 2nd test and was not going any further ....
One more spot, which was very hard to catch as it popped up for a 0,1 second but dissappeared then quickly so I had to record it with the other phone and play very slowly on the PC - it looks like the Asus cover window pops up and it says - move your finger around the circle to get quick access to your preferable apps and there is also a blue button: Do not show again . This is flashing now and then and I do not have Asus Cover, so the behaviour is quite odd to me.
I have a feeling that there might be something with connections, but really I do not know what else - I checked it 30 times and made sure everything was properly alligned and tight when I was changing the PCB with micro USB port.
By the way the other phone works well on PCs, so I must have all drivers installed, it is just the second phone that is half bricked... I'm wondering now if maybe flashing CM 12 or 13 will help, however as it is not rooted probably it will not work via SD card... or? Am I looking in the right direction?

Buddy , its hardware so software tweaks will be useless .

Buddy, we are on the same ****ing boat.
I tried to go back to 6.0,but i got my phone bricked and now i cant reverse it back because i need usb connection to the computer and simply it isnt recognized.
I suggest you to send the phone to the asus assistance centre or to buy a new usb port for your phone,as it is clearly damaged like mine.I need to do it too so if you want to wait me first so i can check if it works,ill maybe save you some money.

Well, my phone successfully reversed to Lolipop, and I changed the USB port, I talked to Asus authorised service centre and they said it will cost the price of the phone, so I just give up, as everything works, but not the phone with the computer via USB and not the quick charging. Asus centre said it is a motherboard failure, but I'm asking how is that possible if all other functions work well???

Yes, I see your point, but I cannot imagine how is this possible, when all other things work well on the phone and the SMMI test shows all sensors working properly?

Ask yourself the same 2 questions again once more
Is your phone recognised by PC ?
Is fast charging working now ?
If answer is no after downgrade .
You know the answer

i changed mainboard and working
well, i have the same problem and i try the following possibility and all unsuccessful.
1. i tried 3 different pcb still no luck
2. i changed sim flex still no luck
3. i changed battery still no luck
4. i changed lcd and digitizer completely still no luck
5. i wiped cache from android recovery MM still no luck
6. i wiped data and factory reset from android recovery MM still no luck
7. i install same latest os (MM) for ze551ml from sd card still no luck
8. i use original ac adapter and cable and tried working different one for every step.
so i want to ask a questions. can it be ground connection somewhere on cases? or motherboard
i am tired but problem found. it is exactly motherboard problem. i bought used original mainboard and all is working.
Note: other mainboard using same android os version so it is not os failure.

USB brick on HTC Desire HD the correct thing I'm on about?

I'm looking mainly if someone can point me in the right direction regarding an issue.
My phone I got off a mate doesn't ask me when I plug it in via USB what I want to do. I understand there are settings that I have changed for it to ask me what to do. Charging works fine with phone off and booted.
I have tryed cables that I know are for data as well as power ( checked both computers and with a kindle and gf's cyanagenmod phone both work.)
Some might say my mate tryed to root it. I have asked him and he only did one over the air update. He has no gain from lying as he said he would pay for repair( replace ment of the USB board as I belive the phone has a upper and lower board.) Trying to save money (hes a mate and I'm not going to mess him about.) and a save a repair that might not be needed or even fix the issue.
I have cleaned the port with a small brush and cables have a normal "snug" fit.
Futher to research on forums I think I might have a USB bricked phone. At one point I unmounted my SD card while USB dev mode on and I got " USB not reconized". At this point I unplugged the phone to then install drivers. Drivers did not work. Now you may think broken but my experince says if the connecter was broken that it wouldn't even charge as I belive the outer pins are the power.
When I look up desire hd USB brick online I get only results for desire phones not desire hd. With desire issues seems that the phone needs to be rooted barr one walkthough that's once again geared towards non hd desire.
My points are-
Am I correct to look at this as my phone could be USB bricked or does this issue only affect the desire model of phone. Belive it could be caused by the ota update.
Has anyone else had this issue? If you got the phone fixed did a lower board replacement correct it?
Any links to further reading or solutions would be great help. I feel I'm failing to describe my issue in the correct terms if it is indeed a USB brick.
Cheers for reading this post, 2nd in length only to my life story...

I also think i dont have a recovery, as when I do a boot holding power and volume down and click recovery its loads for a bit and then shows a phone with a red ! next to it.
Just to learn, I am correct from what I have read that the kernel is just like a modern OS kernel for a laptop/desktop. Its the part that makes the software and hardware talk?
When you got the phone, had the phone gone through a data wipe (factory reset)?
...And you've tried using the USB connection via another computer as well?
...And in the settings, under 'Connect to PC' you have 'Ask' checked?
The phone had a factory reset done via android settings menu and when you hold power and vol down.
Checked settings and it says ask.
No dice on another pc double checked the cable with kindle and data transfer was ok.

I also have the same problem with my desire hd.
Trying different roms didn't seem to fix it.
I'm thinking of sending it for repair.
First i want to flash a stockrom, witch seems quite hard if your USB doesn't work.

Unbricked from QHUSB_DLOAD via MobileTechVideos, USB broken, now unrootable

So I got a bricked Nitro HD from a friend. It was showing the dreaded QHUSB_DLOAD device, meaning it would not go into download mode either. I thought about getting a medusa box and doing the jtag restore myself, but I didn't want to invest so much money. I was trolling ebay for phones with broken screens/cases so I could replace my motherboard, but then I saw that MobileTechVideos would unbrick my device for $50 (plus one way shipping to Bryan, TX).
This was cheaper than buying a for-parts one off ebay, so I decided to do it. But it came back to me in a sorry state:
First, I plugged it into my computer USB port via a cheap type-A-to-micro adapter that worked for my LG vortex. As it started charging I saw they put cyanogenmod 9 on it. But it was freezing every other second. Also the camera didn't work, the wifi was broken, and it would only intermittently detect anything on my computer (lots of that USB detection sound followed by the USB unplug sound). I didn't yet have a SIM card, so I couldn't test the mobile connectivity.
I figured out that it was freezing every other second only when plugged into my computer. It would go from charging to discharging every time it froze. When I plugged it into a normal AC/DC converter it charged with no freezing.
Then I saw that it was a very old nightly build of CM9, so the first thing I did was download a "stable" CM10.zip for the p930. I installed it with CWM from the sdcard. This got the wifi and camera working, but everything else was the same as before.
I took the phone apart and I could see where the soldering had to be done on the circuit board--right next to the USB port. I figured one of the delicate USB signal traces got too much heat.
I got a SIM, which didn't work at all for connecting to a mobile network. The IMEI showed 0, and the baseband was for a different model. I tried to update the baseband and firmware, but that didn't do anything.
Then to my surprise the USB worked when I put it in download mode. I decided to try starting over at the unbricking guide. I put the Korean V10F KDZ on there, which fixed the mobile network connection - I could make calls. But now the WIFI didn't work among other small annoying interface issues with the Korean ROM. Also the USB now did absolutely nothing except charge the battery. No matter the mode, there was no USB communication - not even the flaky intermittent detections I saw before.
So now I'm stuck with no root, no CWM, no custom ROMs. Unless I'm mistaken, every avenue to root the device from V10F involves ADB over USB. But the USB is definitely broken for everything but download mode. Perhaps because the USB traces are good enough for lower USB synchronization speeds, or maybe the USB host for download mode uses different undamaged wire traces?
I think the best I can do now is stock ROMs with no root. I have to say I expected more from the unbricking service.
It occurred to me that it was my friend who put the retarded version of CM9 on the phone, and MobileTechVideos simply restored the booting functionality.
Problem now is that the mobile connectivity WAS working until the carrier banned the phone for having a 0 IMEI. So now I have to find out if that can be repaired without JTAG or ADB.
Hey, I got another USB cable and it works! It was just the adapter that was a piece of crap.
I restored the IMEI with QPST: http://forum.xda-developers.com/showthread.php?t=1802024
Now I can root and install custom roms!

[Q] Is USB connector destroyed?

Hi, all...
Quick question: did somebody in this forum ever had problems with USB? Mine seems to work only for charging. 'Till the last week, it worked as MSC, with no major problems, then it became faulty, disconnecting and connecting.
Now, to have data connection, is necessary to put pressure at the male connector and hold it this way. I think that it'll require a new PCB, as it doesn't look like software failure. I've googled up and there were other people having trouble with Xperia, but not M, specifically.
So, must I bring it to the assistence?
There's only one way to find out where the source of the problem is: to reflash the ROM.
The USB connector might have got damaged somehow. You can try it with any other device or maybe another xperia m to check for software fault or damage of the USB connector. Try to keep your device at a level below the port for USB in your computer.

Tried with CM 4.4 (FXP one, that's, by the way, terrifc). But it presented the same failure, then I reverted to the stock 4.3's CWM backup, because I didn't want to reinstall every app. Well, at least I,'m now sure that's a hardware failure.

Tried everything (or near everything). It charges, however. There are a little failure, but it should work if the phone is left quiet or not shaken while using it connected to the outlet.
So, for now, I'm going to transfer things using Samba or detached SD (the last being the fastest). Later I'll send it for repair... Shame it perhaps won't work with OTG (a feature I've been searching for, when I bought XM), but, when having money, I'm going to get it fixed.
Thanks for the replies, anyway.

Most problems don't get fixed just by restoring /system. You have to flash the whole
ROM, if it failed with system. If you're worried so much about your data, then just backup /data then restore it afterwards...
I also have this problem.i just elevates the charger cable and its charging but its not working if its not elevated.tried different charger but the problem still persist.so i conclude that its the port in the phone that s malfunctioning.

Having a Number of Problems

Hello to all. I am emperiencing a number of problems on my deb. Some are listed below. These problems were not experienced in the first 3 months:
1) THE BATTERY
I cannot use the tablet while charging. It does not charge i.e. It needs to be in a specific position to charge.
Also, I am experiencing Huge Battery Drain. It charges 5-15% in 2:30 hours. This happened after I used the PA 4.5 beta 1(Using MultiROM. This stayed even after I deleted the ROM And reverted back to stock.
2) THE SIM CARD
I don't know when it happened but the sim was working fine before. I didn't use the sim very often except for validating whatsapp. But as I tried to validate, no messages arrived at my nexus. I thought that the sim had become defective. But it worked just fine in other phones!
I even contacted Asus about this but they asked me to first factory reset it. I decided it was too big a deal and did not.
3)THE OTG CABLE
My Nexus recognized the otg usb drive at first. When I tried to use it again, It just wouldn't recognize it. Tried using a mouse too (had worked before). Did not work. Tried on different roms. Nope.
4) USB COMPUTER CONNECTIONS
I had used it before to copy files from my laptop to my nexus. It worked fine. After some time, I tried to do it again, the pc would recognize it sometimes say it was unknown sometimes say it was Nexus 7 but wouldn't install drivers. Tried using Wug's to no avail.
Today, I tried using it on my other pc. The drivers installed just fine, but there was no sign of it in My Computers. In Wug's, the device was able to operate fully! It tried using various backup commands, and they worked! But the push/pull command did not work. Though that turned out to be a problem of the toolkit as I pulled the files I need with ADB PULL command in cmd.
So, as some of these problems are hardware related, I am thinking of giving it back to Asus. I am rooted and performing The Wug's Flash Stock +Unroot Option Now. Please if you have any advice, post it here.
THANKS IN ADVANCE.

Hello to all. I am emperiencing a number of problems on my deb. Some are listed below. These problems were not experienced in the first 3 months:
1) THE BATTERY
I cannot use the tablet while charging. It does not charge i.e. It needs to be in a specific position to charge.
Also, I am experiencing Huge Battery Drain. It charges 5-15% in 2:30 hours. This happened after I used the PA 4.5 beta 1(Using MultiROM. This stayed even after I deleted the ROM And reverted back to stock.
2) THE SIM CARD
I don't know when it happened but the sim was working fine before. I didn't use the sim very often except for validating whatsapp. But as I tried to validate, no messages arrived at my nexus. I thought that the sim had become defective. But it worked just fine in other phones!
I even contacted Asus about this but they asked me to first factory reset it. I decided it was too big a deal and did not.
3)THE OTG CABLE
My Nexus recognized the otg usb drive at first. When I tried to use it again, It just wouldn't recognize it. Tried using a mouse too (had worked before). Did not work. Tried on different roms. Nope.
4) USB COMPUTER CONNECTIONS
I had used it before to copy files from my laptop to my nexus. It worked fine. After some time, I tried to do it again, the pc would recognize it sometimes say it was unknown sometimes say it was Nexus 7 but wouldn't install drivers. Tried using Wug's to no avail.
Today, I tried using it on my other pc. The drivers installed just fine, but there was no sign of it in My Computers. In Wug's, the device was able to operate fully! It tried using various backup commands, and they worked! But the push/pull command did not work. Though that turned out to be a problem of the toolkit as I pulled the files I need with ADB PULL command in cmd.
So, as some of these problems are hardware related, I am thinking of giving it back to Asus. I am rooted and performing The Wug's Flash Stock +Unroot Option Now. Please if you have any advice, post it here.
THANKS IN ADVANCE.

Judging from the symptoms, you likely have a bad usb port. I wouldn't say the cable since your otg cable yielded the same result. According to some, it's really fragile when you handle it rough. The port is soldered to the I/O board so either you (1) try to bend back the inside pins; or (2) replace it if you're skillful enough with your iron; or (3) replace the board (ouch!). It's a shame if you have to choose (3) since that means throwing the board away for just one bad component. Litter.
1) The inside pin is fine. The cable just seems really loose. Though the other cables have the same effect.
2)I dont have the skill.
3)Why should I waste any money if It is under warranty?
And usb otg should come at least once, as the tab does charge once maintained in a specific condition.
And As the tablet charges when its connected to a pc, its not a problem of bad usb port

I didn't realize your tab was still under warranty. Nevertheless, the fact that the cables fit loosely suggest that the housing is not in good condition and the pins, in turn, while not damaged, make poor connection (to wit, the tab charged only if held in a certain position). If the tab consistently charges while connected to a PC, then you're right, the fault lies elsewhere, like a jarred battery connector, or the other USB end, or the charger itself. This, however, leaves the OTG issue unexplained. Warranty seems your best bet for the moment, however. Good luck.
I don't think it can be a mistake of mine, so Asus will definitely have to replace it.
Thanks for your support though!

P8000 shuts down randomly

Hello.
I own a elephone P8000, bought 3 months ago. It's a great phone, I've been enjoying it so far, but just recently this issue has appeared, and has made the phone unusable: it shuts down randomly by itself. I can be using for just 30 seconds, or even leaving it on its own (it lasted this whole night on standby without shutting down, however after using it for like 10 seconds in the morning, when I went back to check it it was off), it shuts down, and I can't power it up again unless I connect it to a power source (like a recharging cable) - I press the power button and nothing happens. However, after being plugged in to a power source, I can then start it up. Also, when it's connected, I can use it for as long as I want and it wont shut down, however when I unplug the cable, it may last 30 seconds or even a few minutes, and it will eventually shut down. This happens with every percentage of battery, as I've tried it with low battery (around 20€), and full.
The only thing I've done so far was do a factory reset through the android settings menu (not the android boot /recover mode menu).
Any thoughts? Would really like to try everything possible before sending it back to Elephone for warranty as it would take me to pay for the shipping...
Thanks in advance
It's one of three things in my opinion.
1. The battery is faulty.
2. The USB port is bad (I sort of doubt it is this). You could also try a different outlet adapter, and USB cable to rule those out.
3. Something process wise in the OS is rapidly consuming power.
Have you tried to install an alternate ROM via SPflash? I'm running CM12.1 on my P8000 US B version, and it has been flawless since I've gotten the phone in June.

I've considered the first and the last option. I just hope that it's not the battery. If it is, is it easy to replace the battery, since it's "stuck" into the phone itself?
I'll try to install a different ROM, however I can't access the android's boot menu / recovery mode. Once I press the Volume UP and POWER button, and it goes into the recovery mode, a red triangle with a ! appears and can't go to that menu. I've looked around for a solutions but everyone says different things. Would you know how to fix it?
Thanks again
Do a quick search on YouTube for elephone P8000 battery replacement, p8000 rooting, and p8000 installing twrp recovery. I put up a 15 minute video of recovering the P8000 from dead bricked state.

I'm sorry mate, I consider myself an educated guy on computer stuff, but smart phones isn't really my thing. What steps in order to install that new ROM should I take first? Let me remind you that I can't go do the Android Recover Menu, so should I do something first to re-install it? Sorry about my ignorance on this, I'll try to read about it on my own untill I wait for your answer tho
First off, what version P8000 do you have? American ("B") or the Euro model ("A")? You need to d'load TWRP recovery first (links in description in my video). Install SPflash on your pc , and install the recovery to your phone using SPflash. TWRP recovery will allow you to install zip files of ROMs, super root, kernels, and backup your phone. The recovery that ships with the P8000 is stock only, and you cannot install ROMs with stock recovery. So your first step is getting TWRP recovery installed.
Any possibility you could shoot a short video of what phone is doing after you unplug it?

Hey mate. First of all, thanks for the help and the time spent.
I've read and tried a few things yesterday, I'm more aware of what you told me to do now.
My P8000 is the Euro model, from China (?). I'm from Portugal tho.
I've downloaded SPFlash, TWRP and the stock ROM just to give it a try first with this rooting and flashing stuff. When I connect my phone with it on and with the cable attached, it downloads a driver. I've also manually tried to install the drivers around here from the forum. When it's on, I can access to the phone's files and all of that. However, when the phone is off, and I press "Download" on SPFlash, and then connect the phone while off, the windows does a sound of device plugged in and the the sound of it plugged off, and the phone shows that battery icon recharging. So, basically, nothing happens with SPFlash when I connect the phone. What can I do to fix this part?
About the video, the phone basically shuts down after I unplug it mate. It can last either a few seconds or even a few minutes on, but it shuts down anyway. And is not from a specific action, like opening an app or something, it just goes off randomly. If it's really necessary I can do the video tho.
If you are running Windows 10 64bit you will need to disable driver signing, and install the Media Tek drivers.

I'm running Windows 7 64bits, and even tho a pop up window appear when I'm installing the drivers asking me if I authorize them to be installed and I press Yes, they seem to be installed perfectly. Kinda lost here, as I can't connect the phone to SPFlash because of this
I had to get driver signing disabled before drivers installed properly on Windows 10. I'm fairly certain the same applies to Windows 7. Do a quick YouTube search for MTK drivers, and Windows 7 and follow along step-by-step. Watching a SPflash windows install video wouldn't hurt either.
You defiantly need to rule out that it is not software related. Have you attempted to contract Elephone support to see if they thought it may be hardware or os related? You've tried different USB cables, and a different wall plug? I've had USB cables that my p8000 won't charge at all from. Sometimes a bad cable or bad power adapter will actually drain the battery.

I want to give a try at this regarding the SO before spending money on a new battery, even tho they aren't that expensive. I'll try everything today again, from the start.
I did, and all they said was
dear friend
i am sorry to hear that, may you can buy a new battery to try if it work
good day

I did tried all those things. I'll give it a last try on trying to change its ROM, if I succeed and the problem stays, I'll buy a new battery and try it out.
Thanks for the help mate!
Were you able to get SPflash working? TWRP installed? If you have a friend that has Ubuntu Linux installed with a few minor settings changes, SPflash runs flawless on it

Hey mate, just tried it all again. Removed W7 drivers signature enforcement, reinstalled the drivers, and tried again running SPFlash. The programs opens, I select the scatter file from the the TWRP recovery folder. However, when I press Download, and connect the phone to the cable, nothing happens in the problem. Windows makes a sound of device connected, and lke 5 seconds later it makes the sound of device disconnected. After that the phone goes into that battery charging mode, and a battery appears in the screen.
It sucks to be stuck right in the first step of the whole process, god's sake. Is it possible to install TWRP another way than from SPFlash? I've read about installing those things from the SDcard in Android boot menu, could give it a try
You can try via ADB:
http://www.theandroidsoul.com/how-t...tboot-with-drivers-on-windows-quickest-setup/
http://androiding.how/how-to-install-twrp-recovery-via-fastboot/
Odds are if you still cannot install via ADB it is most likely a Windows driver issue.
Also, here is is a good article on other ways to troubleshoot P8000 battery issues.

Alright, got some news! I managed to get SPFlash working (just changed the PC USB port, yeah, basic thing lol). Tried Flyme ROM and GM 12.1 and in both ROMs the issue still happened. With all this done, anything software wise should have been fixed, right? So, now, moving to the hardware, should I just admit, after this, that the problem is in fact the battery?

Well, firstly, if you power off the phone, and plugin the P8000 with a power adapter/usb what percentage does the display show the battery?
Secondly, if the phone was wiped clean, and installed a new ROM, odds are it is not OS related. I would at the very minimum try some of the battery techniques listed here: https://www.orduh.com/fix-elephone-p8000-battery-drain-overheating/ before buying a new battery, and tearing apart your phone.
Thirdly, about one month ago, my finger print scanner on my phone started acting quirky. I removed the back cover, and with my thumb, I applied firm pressure right where I could visibly see the ribbon cable for the scanner and applied firm pressure vertically down the battery. That fixed the loose ribbon connection without taking the phone apart, and the finger print scanner works normally. Try the same technique with the battery. Apply firm pressure along all edges of the battery all around the battery, and down the middle of the battery in case there is a poor connection between the ribbon cable, and the battery. If the website and pressure techniques do not work, odds are it' a defective battery. If the phone is under a year old, see if you can pressure Elephone into shipping you a new battery free of charge. Good Luck.
PS
I assume you were able to get TRWP recovery installed? Once you have the battery issue resolved you will have a much more flexible phone. With the right ROM + kernel this phone kicks serious ass for battery life, and performance.

When the phone is off and charding, the percentage shown is 100%. The issue started at a day when it was around 20% or so, but since I had to have the phone plugged in so I could use it, it eventually charged up to 100%.
I will try some of the things described in that website, as well as that technique you told me.
Not really sure about Elephone sending a new battery, their costumer service seems to be really bad when it comes to that kind of things.
I did managed to install TWRP! When I get my phone fix (which I hopefully will get), I'll definitely get into that kind of modifications! You've recommended GM12.1 as ROM, right? That was the last one I installed.
Thanks for all the help mate!
I use CM12.1 (CyanogenMod). Lighter android, efficient, and everything works flawlessly. With these custom aokp ROMs Google play store must be installed through TWRP. Both CM & Google are installed as .zip files through twrp

I've ordered a new battery from Ebay. I bought the phone on AntLife, after contacting them they said they would refund me the battery, however they now only claim they will give me a 10$ cuppon on my next shop there lol.
Really missing my phone, been using an old crappy one for weeks now ahaha.
