S10e Rapid Failure Help

[nuke11]

Hi folks,

Looking for any thoughts or advice that could be of assistance for dealing with what appears to be the complete and rapid failure of my Galaxy S10e, purchased four years ago. Last night it was working perfectly normally, as it always has. Then, while on Chrome it suddenly hanged and was completely unresponsive. It then entered an endless boot loop, where it would boot with the power on vibration to the initial screen that has the green Android logo and says something like "Samsung Galaxy S10e secured by Knox". It would sit for 10 seconds or so, go back to a blank screen then do the exact same thing again over and over.

Attempting the forced reset button combo (vol- & power for 7 seconds) did nothing to this loop. Doing the recovery boot (vol+, Bixby, & power), caused it go into the RDX watchdog screen, usually with "CPU Hang" displayed. From here, if I exited, it would just go back into the boot loop. I let the battery drain based on the experience people have had of being able to get to the recovery options menu by having the phone power off completely (which could only be achieved by letting it die), then booting directly into recovery following a short charge with it off.

Well when I plugged it in to charge this morning, it briefly popped up the same initial boot screen as before, then went off and has been completely unresponsive since. Leaving it charging has done nothing, there is no charging screen of any kind, and the phone does not feel warm like it has current flowing. I presume it is dead dead.

Of course, I would like to recover everything I can off of it, but it seems to be unable to even charge at this point. I'm guessing some nascent hardware fault that was lurking within failed catastrophically? Probably something in the power supply?

Any advice would be helpful. I can take it to a repair shop to hopefully recover things, but I am out of town. I have technical knowledge, though not deep in the electronic/Android world, so feel free to get into technical discussion if it could help. Just looking for anything obvious I might be missing or just hope that the data is recoverable.

I appreciate it.

Okay so an update from here. I had left it on the charger for a while, and just saw it reentered the boot loop. I've attached a screenshot of the RDX screen. Seems like I can't exit the boot loop still. Any advice? Or a thread where this has been resolved before? I couldn't find anything yesterday.

Hi welcome to AC!

Your best chance with trying to save Data would be flash the stock firmware with Odin and Frija tools download the latest from XDA site and I'll guide you through the process.
Is your S10 US version or international?

Hi mustang, thanks for reaching out. It is a US version. S10e rather than S10. I think there is some kind of internal power supply issue at this point. I was able to get it to recovery mode while it was in the boot cycle. I wiped the cache in the hopes that it was a software fault, but it wouldn't resume restarting. It booted to the initial boot screen and hung for a while, then went black and has not done anything since. It was warm while in the boot cycle (I left it charging), but now it is cold again while still on the charger. Any thoughts on whether I would even be able to flash it with these symptoms?

Hi,
The battery will need at least 50% to proceed on flashing it

Understood. I haven't been able to get any indication of charge status since it started all this last night. It still won't load the charging screen with it off and plugged in.

Let it charge for about 2 hours then can proceed with the flashing

Hi apologies for the delay, I got back in town yesterday, so I have access to my computer now. I did take the phone by a shop yesterday to get their thoughts. They cleaned the charging port and connected it to their charger and found it was barely drawing any current from the charger. The store manager said the boot loop symptoms often happen when the phone can't read the SSD. I'm wondering if that might be the case here as to why the phone doesn't enter even the charge state? They ordered a new screen and battery to try in the event that one of those are the problem. Is flashing even a possibility in its current state?

Without a good charge or data transfer you can't flash it

Thanks, I kind of figured... Since data recovery is the only goal, and assuming the new screen/battery doesn't work, isn't there some way to read the hard drive externally from the phone? I'm thinking in terms of PCs, disconnecting a hard drive from a failed MB and reading it on a working one, you know? If I had, say another fully working S10e, would that be possible? Or is it too integrated to the phone's inner workings?

These devices now are encrypted once you set up the account on them to protect your data , you would probably need someone with forensic ability to get into it but the cost if they could be very expensive.
If they put a new screen and battery they will most likely wipe the device unless Samsung doing the repair you can ask if they could save your data, see what they say .
