After some good years, freeze appears on my S3 i9300 with bootloop

Following advice of LKHN, i have restore my phone to stock rom, root it and install TWRP
I was able to start TWRP one time then everytime I freeze on TWRP splash screen and phone reboot.
If I let my phone start on stock rom, it freeze and reboot on the first screen where you have to choose language

I have buy a new battery but problem are still present

Do you have an idea ?

My S3 was freezing all time, I've tried different roms and all systems I've read online and nothing. After one year no use at all I've installed the rom 5 spanish one from Orange, the last one, and ALL PERFECT. Im so surprised, no freezes anymore for some months.

Lightbulb S3 Black Screen Freezing Fix - Sudden Death Syndrome
Thank you @nhariamine for this thread and your post #1.

I suddenly got some daily black screen freezing problems more & more when running a custom NeatRomLite Samsung based 4.3 ROM on my S3 i9300 after years of using it without any problems & that's what got me to try the Official LineageOS 14.1 S3 i9300 ROM 5 weeks ago.

I also got some freezing problems after a messy first Lineage install so right after booting in a new clean LineageOS install I ran this sequence 4 times to try to fix the random freezing problem as recommended by several S3 users in this thread:
  1. Dummy file Generator > Internal memory > (keep file size default) Generate dummy files until Storage is full. The app may seem to freeze because of damaged memory blocks before reaching 100% full so wait 10 minutes and if it does not get unstock hit Cancel and run it again & it will get higher the next time you do it.
  2. Delete all the dummy files. Close the app.
  3. Run Trimmer (helps to restore NAND Chips performance, requires ROOT).
  4. Repeat both apps 4 times. (screenshots)
Read the 2 apps reviews by S3 users.

I also replaced my broken plastic power button jammed in the depress position & bought a new OEM USB cable as it was also freezing when charging. No more freezing since a couple of weeks 3 months.

This thread is mentioned in a 34C3 talk on the freezing issue. If you are interested in GS3 and eMMC hacking you will love this talk. Oran Avraham gives great history, explanations and hacking details on this problem.
