When you tried re-installiing Raspbian (Lite, Desktop or Full?) did you just (attempt to) re-use the existing uSDHC card or use a fresh (new) one?BatteryNone wrote: ↑Tue Apr 28, 2020 2:04 pmI have usually connected USB Flash Drive and wireless keyboard+mouse. Yes, I tried connecting using SSH - no luck. It just reboots after I get an error. I tried everything, unplugging USB devices, connecting new ones, I tried reinstalling Raspbian, tried powering it from different source...

O.K. That, hopefully, suggests it's maybe not an "SD card issue" but, for completeness, what method did you use to write the O.S. to the SD card and with what hardware? My current preferred approach would be to use the new Imager Tool ( https://www.raspberrypi.org/blog/raspbe ... g-utility/ ) and a known (labelled) SDHC compatible USB-based card reader. Do you know how to enable WiFi and SSH on a (potentially) headless setup?** W/o that ability and/or access to something like one of these: https://www.cpmspectrepi.uk/raspberry_p ... pters.htmlBatteryNone wrote: ↑Tue Apr 28, 2020 2:58 pmSo I took another SD Card and installed Raspbian Lite. After booting it gives same errors as last time, but there is more text and info.

However those 'photo's do show something else that's important - the lightning bolt icon, top right, means that your power supply is poor - that's the low voltage warning! What are you using?BatteryNone wrote: ↑Tue Apr 28, 2020 5:09 pmYes, I am using the official Raspberry Pi Imager you mentioned. And for SD Card adapter... I am using one supplied with this specific Micro SD Card. SSH is not working even though I turned it on before raspberry pi broke. Raspberry Pi doesn't even boot to desktop. It just starts, gives errors and reboot. I'm also putting here some photos of some errors. I didn't capture all, but those common onces.

You might have got away with a "Y" lead that uses two USB ports for input (often supplied with USB2 disk "caddies" for 2.5" HDD's) assuming each port could supply 0.5A but, quite often, all the port's (like on the Pi) power (out) pins are connected in parallel. Phone chargers are not that reliable - I've assessed quite a few: https://www.cpmspectrepi.uk/raspberry_p ... plies.html (some before I received my first Pi, back in 2012).BatteryNone wrote: ↑Tue Apr 28, 2020 5:18 pmYou will probably have a good laugh about this, but my phone charger is too weak, so I am powering my Raspberry Pi from PS4 USB port![]()

BatteryNone wrote: ↑Tue Apr 28, 2020 6:02 pmSo I tried power supply with very similar specs as the official Raspberry Pi power supply. No luck, it still doesn't work.

The unsuitable phone charger may have partially triggered some of the protection circuitry (eg. the polyfuse) . Re-try it with a better supply after at least 48hrs has passed. What length of connecting cable was being used? (Poor quality, too long cables can also give rise to low-voltage issues). The official power supplies were designed specifically to deal with the issues associated with "generic" phone chargers as the capabilities and associated power requirements of the various Pi models developed since 2012 changed especially for the B+ onwards which were expected to be supplied with enough spare capacity to power a connected USB HDD.BatteryNone wrote: ↑Tue Apr 28, 2020 6:10 pmBut still, it worked to this day with no problem running on phone chargers, PS4 USBs, etc. So why it would one day decide that it would not run on phone chargers, but on power supplies?
