[Completed] LG Google Nexus 4

My device fails to remain switched on. After some while it switches off. Sometimes it seems something like turning on wifi toggles it but not sure. I have tried both soft and hard factory reset but still there was no use. It heats up a lot due to continuos loop of on/off. But when I switch it on, it is not completely switched on and somewhat stops in the middle of the process. It turns on only when I connect to a charger but within half an hour It heats up a lot. The battery is not drained when I switch it on. Also when once switched off it does not switch on on its own. So, i feel its not a hardware issue. Can you guide me regarding the problem with my device-LG Google Nexus 4.

Phone dead

Hi: I searched the forum but haven't found this issue discussed. Today my phone went completely dead. I had it with me off the charger for several hours while out for a Sunday drive. It was odd as it disconnected from the car bluetooth - I think that was due to power optimization turning things off. I still had over 90% battery. When I got home, I put the phone on the charger. An hour later, I went to use it and nothing. No screen, just dead. Holding power button did nothing. Yikes!!! I did a Google search and found discussion about this on the OnePlus forum. Apparently holding the Power button + Volume Up recovers the phone, and it worked for me. I am completely stock, no root, no bootloader unlock, latest version 9.5.9.GM21AA.
Any thoughts on why this is happening? Any insight would be appreciated.
Thanks.

Sorry to hear about your phone but it is something which is not new. It has happened to me twice in a span of three weeks and has happened to other people as well. Unfortunately no one knows the root cause of this particular problem but I am sure soon it will be identified and hopefully cured. I am rooted with twrp and running a custom rom and a few magisk modules. Sorry can't be of any more help, cheers.

There's a few threads about this had happened to quite a few people. Here's one of them.
https://forum.xda-developers.com/oneplus-7-pro/help/op7pro-off-wont-hold-power-volume-t3945515

I met the problem several time, VOLUME UP + POWER Button works. But it is really annoying.

I have this problem with 9.5.8 & Smurf kernel. But after disable mq io sched, everything is fine. I thought Oneplus fixed this issue. Hmm, they didn't.

[CLOSED] Dead S6

Hello,
recently my old galaxy S6 is dead with all my datas inside, no response on charging cable, no response on power button combinations, it's completely dead.
I've buyed a new battery and this does not solve the problem.
I've tried to connect and disconnect the battery and, sometimes, after i touch the power connector on the phone with my finger and connect the battery a white battery with a lightning bolt appears, or if i'm lucky the green charging battery appears: in this case, if i try to boot the phone the boot begins, but the phone freeze during the boot. For example, last time the screen froze with the SA of SAMSUNG appearing and the only thing i can do is to disconnect and reconnect the battery.
With this in mind i'm thinking about two possibilities:
- The motherboard is broken
- The battery connector on the phone is broken
Am i correct?
How do i verify if the battery connector is broken?, i was thinking about trying with a multimeter, but i really don't have idea how to use it and check, what do you think about this?
Thank you in advance.

Question Realme Gt Neo 2 Won't turn on

Hi there. I came here on last resort.. Yesterday after I did the last update of the security patch (december 2022 I believe), the phone rebooted just fine, and after about 5-10 minutes it froze. Screen on and simply froze. A bit after the screen went off. After 2 -3 minutes like this I tried to force restart it by holding the power button and It did vibrate altough the screen didn't turn on and it didn't reboot.
Today and even after having it charging for a while it's just dead.. Doesn't turn on, can't put in it recovery mode also, nothing.
I have no idea what happened but I can't do much.
Any advice guys?
Appreciate in advance.

The same here. I can't even boot into recovery mode. I have no idea how they're going to fix this problem. Figures - this is the first Android phone that I haven't mess with i.e. root, etc.

Well I cannot be without phone and even after being charging for more than 5 hours, there wasn't even a signal of life on it. Nothing. I also couldn't even do a backup or something. Frustrating.
Bought it on amazon last year. Spoke to them and they will refund the value. Will send it back and already bought another phone. (Redmi note 11 pro).
Regarding this is just very very bad. Stuff like this cannot happen after an oficial update.
Bye Gt2 :'c

Have no Idea of what they will do because the phone is dead pretty much.. Think this is only fixable by going to a store or something...

Unless the phone is working except the screen is off I can't see it being easily fixed. I bought my off Aliexpress so I might **** out of luck.

I tried to see if it would make some noise like if the phone was working and screen off but nothing.. IDK but this really sucks. Maybe trie to contact realme directly?

I tried plugging the phone into my computer to see if it was recognized by WIndows but nothing. I have contacted them via email and Aliexpress message board but these Chinese companies aren't known for having good customer service. It's a shame for I quite like the phone. May I ask what you bought as a replacement?

I also did that but nothing. Initially I tought it could be the battery. It was either that or the update but if you also had it then for sure it was the update and there's probably more with the same problem.. Can only wish you luck with the customer support..
I've bought the xiaomi redmi note 11 pro. I just searched similar priced phones compared to what I paid for the realme(320€) and that was the best option for the price. It costed 289€. The 6gb variant. It's not a direct competitor but it's more than enough for me and it offers a lot for the price. I also had a few xiaomis before and I don't have complaints. I checked the realme 9 pro but the xiaomi was cheaper and has better specs overall.

Thanks for the update - Good luck with the new phone.

hi to all, the device is in EDL mode?
So it means you cannot acces recovery, fastboot mode and also you cannot boot your phone!

Thanks for the response. After setting up a new Oneplus 9 Pro by changing the the firmware from T-Mobile to basic Global. I'm able to get into EDL mode . I also have the correct drivers installed in WIndows so it appears in the Device Manager when in EDL mode. I also have the current firm. I just need a working version of the MSM program.

Something similar happened to me yesterday twice, device suddenly turned off while I wasn't even looking, and wouldn't turn on again no matter how much time I'd press the power button.
However; When I held Power Button + Volume UP for a few seconds, the device did turn ON back again.

Geez this worked perfectly, you are a lifesaver!! After holding the Power Button + Volume Up my device did turn ON. I faced all similar issues mentioned in this thread related to booting after the screen went black while using it.
