[Q] Nexus One restarts when wifi turned on

Hi all. After the 2.3.3 (build GRI40) update but not immediately after (a few days later), my Nexus One keeps restarting in a loop of about 5-6 seconds. Once it crashes, it goes the the 'X' splash screen for about 7 seconds, then to the home screen for 5-6 seconds and repeats indefinitely.
I have managed to work out that it is directly related to the wifi. When I do a hard reset and don't turn wifi on, then it works fine without crashing, including mobile network connection. However, as soon as the wifi is tuned on, it goes into the restart loop. I've tried many factory resets and it is reproducible whenever wifi is on.
Does it sound like a hardware or software problem? Anyone else experienced similar? Any ideas or help would be greatly appreciated.
Thanks

[Q] Hardware issue with low signal and sleep mode?

I've had my One for 3 days now and i've noticed something rather worrying, when i'm in a low signal area (like my office) after 15 minutes or so in sleep mode it suffers what can be described as the "sleep of death". Pressing power doesn't actually bring the phone out of sleep at all and I have to do a 10 second press to restart it.
I've tried switching off all the power management functions in the options but it still does it, did a factory reset and its just started doing it again now.
As i'm having to a 10 second press i'd assume that its crashed instead of switched off, as its only 5 seconds to switch it on from off. Its not overheating which I've seen reported elsewhere and i'm now completely stuck for ideas.
Has anyone else had the same? or does anyone know whats happening? I'm planning to take it back to the carrier tomorrow for repair/replacement.
[Edit]
This is on the stock Three UK 4.1.2 release.

Freezes, reboot and other funky things

Sorry for my bad English
Hello friends of the forum, I present my problem. I was given to repair a S3 LTE really is driving me crazy. We'll explain: the owner did filth with ROM to the point to make it unusable. Turns on, but after a while it stops and turns itself off. I tried to flash the stock, wipe system etc .. from recovery and put back the stock, but every time I turn on the phone and get to the Initial Setup (the one that says Samsung GALAXY which allows choosing the language) crashes and off. Also known that the recovery is very very slow (both TWRP that stock that cwm). I managed to flash rom 2 including Cyanogenmod but this crashes. Sometimes the poor cell can not even start that hangs on and off. I tried to replace the battery with one that I already had and the situation does not change. I wanted to try to do an update of the bootloader because I think the problem is the. Further inform you that when it crashes but is charging if I remove the battery on the phone stays on but completely locked and I can not even press the power button for 3 seconds, because it is completely freezed. Another observation I have noticed is that if I leave him in charge when switched off the led solid red, the screen shows no signs of life and if the detachment micro usb LED remains lit sign that is completely blocked even when it is charging (WHILE TURNED OFF!). I hope you can help. I tried everything

Maybe it's power button problem.Check the power On/Off .

OnePlus 3T hanging and rebooting

My OnePlus 3T(Android Pie) hangs, the screen is stuck for like a few seconds and just reboots. I have tried formatting but the same thing happens. This even happens in recovery mode sometimes. I tried flashing the original firmware(unbricking method) which came with the phone but still it happens. I feel that there is some hardware issue but still I'm not totally sure because in fastboot mode this doesn't happen neither while charging when it's switched off. Do I have any other options?

Redmi Note 9 Shutting off and going into bootloop

Hello o/
My Redmi note 9 keeps turning off automatically when not charging and when I turn it on it shows the MIUI logo but then screen goes black after 2-3 seconds, the same keeps happening if I hold on to the power button or charge the phone, it'll buzz and show the logo and go black and repeat. I can't access the "Volume UP + Power button" mode but I can access the fastboot mode.
I don't know much about "fastboot" or "flashing" so help me out, a video I watched made me download the stock rom for redmi note 9 (from the official website) but I don't know what to do with it.
When I first had this issue I looked at a fix that involved tapping the phone, pressing it and cooling it in the freezer for 15 mins. I don't know if those methods helped but my phone started at a random attempt, after which I did a factory reset, I didn't get any issue but after a few days the same problem occurred again, I repeated the methods and managed to turn on the phone and did a reset again after which my phone worked for a few weeks but now the same problem has occurred again and I can't get to work. I gave up last night and now in the morning it turned on (had 94% battery) and placed it on charge, but after a while I removed it from charge and it went black in a few minutes.
At first I thought the issue is because of the battery but its always charged when the problem occurs so i'm not sure : /
Also there are two options to download, recovery and fastboot ROM... I downloaded the recovery one but idk if its the correct one

Yeah I have the exact same problem, I haven't found a solution yet. This appears to be happening to a lot of people

I found a solution. It's not a software issue, it's a hardware issue with the fuse on the battery. The solution is to open the phone back and apply some more solder on the fuse. I did it yesterday and it completely solved my problem. Following this video :
