Before posting check out the following points and please reply answering them :
1- Have you installed the OS as described in the tutorial?
2- Have you cleaned the memory card with diskpart or similar to make sure no partition is left? (in particular if you tried to flash several times)
3- Have you formated in FAT32 ? Formating in ExFAT for example will cause crashes/boot problems.
4- Are you waiting for ~10 seconds for LCD to get signal? First 10s it's expected to have blue/white LCD before signal switch to LCD.
5 - Do you have something connected to USB when that happens? Some power hungry devices might crash the system.
6- With what software have your flashed the OS on the memory card? (not just dropping the .img file on the memory card)
7 - Have you tried to clean microSD with diskpart, format in Fat32, flash again?
8- Is you battery low/empty (LED2 turns ON when low battery)? LCD starts flipping when battery is low.
9- Are you using a 5V 2A charger? Using a 5V 1A will result in battery not charging. Low battery results in screen fliping.
10- What version of Retrorangepi are you using? RetroStone version? SLIM or FULL version? Latest version?
11- Are you turning OFF from software before switching OFF the switch? RetroStone is a computer, if you hard-shutdown directly with the switch you might corrupt your OS. If you did switch off with switch rather than software and have problem since, please try clean SD card, format and reflash.
12- Have you tried to re-download the Retrorangepi image, just to make sure it wasn't corrupted while downloading?
Check the image size, if you download had a problem it will probably be different than the following :
13- By chance do you have another microSD card to test if it's the SD the problem?RetrOrangePi_4.2_FULL_Armbian_5.59_Retrostone_Debian_jessie_default_3.4.113_desktop.7z
1.18GB zipped (1,183,605,850bytes)
4.27GB unzipped (4,269,801,472 bytes)
13b - Have you tried with another computer? Some people report that it was the issue (probably the SD card reader that was making errors while writing or something like this)
14- Can you test the following procedure : (not necessary if you tried surpemeretrostone v1.1
Does it help?Step 1 : From emulationstation, quit to terminal (F4),
Step 2 : type in the command : sudo h3consumption -d 528
Step 3 : Type : sudo reboot
15- You have a hardware problem? Game crashing and returning to emulation station are software problem. Retrostone crashing, turning OFF or showing blue lines are hardware problem. Please describe your problem.
16- What is your backer number/order number ?
Please note that RetroStone not booting occasionaly is not a hardware problem. There's a specific boot problem that occurs about 1 time every 5 times (LCD will stays white/blue for longer than 15-20 seconds). When that happens you can just switch off and on again. We'r working on a software fix for that one.
Hardware problems are when you can't boot at all, or that when you boot you don't have a stable system (crashing after 5 minutes shuting down and so on...).
I'll get in touch with you to organize replacement of it.
