Phone won't turn ON or Charge.

Hi, guys! I had a similar issue: my oneplus was on around 15% when it just switched off. I put it on charge overnight but in the morning it did not turn on at all no matter how long i was pressing the power button.
I went on some forums and saw ppl recommending to leave the phone on charge for 12h and try again - did not work. power button + volume down also did not work, nor did taking out my sim card.

When i pressed volume up + power though i saw a quick message on the screen that the battery was too low on charge (below 1 per cent). I then tried another piece of advice and put my phone on a charge via laptop - and it worked!

I charged it enough to turn it on and then transferred it to charge from a power socket - works now
Uiii, i dont have to go to the repair shop
Hope it will help someone ^^

I replace the battery but it solved not the problem.

Hi Thomas

i think it is better you can go to a local repaire service guy to identify the root caused: Battery issue/power IC issue/CPU Issue/USB Board.

1. battery issue, it is easy to replace with a battery and fixed it.

2. if it is concern to motherboard, i think it is not easy for you identify it, it maybe need replace with a motherboard.

3. if it is USB Board issue, it will be easy to buy a USB Board.

Thanks

Jack.

Hi

My 1+1 was dead the whole night. any idea how long does it take to charge. no led light while charging. phone is not responding to power on button. i even tried holding power button and volume down button . no response. probably it is been charging for more than half an hour now. help please

Sometimes on a dead phone you have to hold the power button for a long time. Mine would vibrate but not turn on. but after a USB port and Battery change it worked. If you don’t feel the vibrate from the power button hold then you may have a broken power button $2.50. You can send me the phone and I will try to revive it. $50 not including parts.

It’s a great phone and worth it if your strapped for cash.

I had the same symptoms on my phone, wouldn’t go past 50%, wouldn’t really show it’s discharging. I would reset it a million times, and sometimes while powered up I would get in and it would go back to normal. Oddly enough I noticed that when i would set my phone down, it would revert back to the 50% and the LED charging light would turn off again. So… I wondered, hmm maybe it is the USB port, i forced the charger pin inside the port down a bit, hooked up the cable and pull it down a bit (my cable isn’t in top notch shape but it works). AAAnnnndddd VOILA,,,, charging LED turned on, and the battery went back to normal and it would say charging again, fiddling with the cable a bit or pulling it in the wrong direction and boom the light would turn off and we’re back to zero. So, in my case, it is a damaged port, I mean the phone is well over 5 years old now and it’s still going.

My solution, really pull down on the pin and it’s been working for a day now again. I ordered a replacement usb port and a battery just in case, but those things take time to get to me (1-2 months). For now it’s fine, I do have a oneplus 7 pro i bought recently as my main phone now, but I’m determined to restore my OPO back to normal with those fixes.

(SOLVED) you will need an EDL deep flash cable and some basic tech skills and know how, My oneplus 8t had gone dead after I carelessly flashed the wrong XML img to my phone meant for a variant with different ram. I had seriously thought my phone was super bricked. I tried everything from letting it sit until the battery would normally be dead and then charging for a 12-14hr cycle, and then turning back on with every button combination for every conceivable time intervals possible , both plugged into and unplugged (computer & wall charger). I even made myself an EDL deep flash cable and tried combinations with that. Nothing worked and I was close to writing it off, but then I thought, most phones have test pins for EDL mode, if the deep flash cable doesn't work. Heres what I did. Take a heat gun and heat the back of the phone around the outside to soften adhesive, take a card or thin plastic object and carefully pry off the back. You will want to remove the camera modules with has 4-5 tabs to the board, this will expose the two EDL test pins. Before shorting them out, disconnect the battery and more importantly, HOLD DOWN POWER BUTTON FOR AT LEAST 30 SECONDS TO DRAIN ALL POWER! Then reconnect the battery and immediately short the pins for at least 10-15sec. Then connect EDL cable first to your phone, then while holding the button on the cable, connect to PC. You should have the MSMTOOL ready and waiting for device at this point. If the phone is not acknowledged as connected by p.c at this point, LEAVE IT CONNECTED, and vol+, vol- and power at the same time for 10-15 seconds. This is what saved my phone, I hope that it helps to save yours as well..
