Samsung S10 install instructions need an update

Installation Help
1

I helped my friend to install IodeOS 7.5 on their Samsung Galaxy S10 a while ago and hit several walls during the process. Ultimately we managed to get it working but it was a 3h process with all the hurdles. Thought I’d share the things I noticed, perhaps it can help someone, and perhaps the official instructions can be updated after verification.

Below you can find the instructions as they stand today, with my comments. It’s been a month or so, but I did my best trying to remember everything :smiley:

S10, S10e, S10+

  1. Unlock OEM in developer settings

→ After resetting the phone, it had to be online to make this option visible. See e.g. https://xdaforums.com/t/no-bootloader-oem-unlock-option.3926688/

  1. Activate adb and type adb reboot bootloader, or shut down phone and press Vol- + Bixby while plugging to computer

→ The first option (adb reboot bootloader) did not get us to the correct screen, we had to use the second option (Vol- + Bixby).

  1. In Download Mode (DL), long press Vol+ and unlock bootloader

  2. Reboot to DL mode & flash recovery for S10 | recovery for S10e | recovery for S10+ with command: heimdall flash --RECOVERY <recovery_filename>.img

→ Had to install heimdall first. Could be mentioned in the beginning a prerequisite?

→ Now these last parts (or 4 and 7 specifically) caused perhaps the strangest hickups, but unfortunately I can’t remember how they went exactly. I think this heimdall flashing “stopped” at 47%, which was a bit concerning, but turns out it was fine (like here https://www.reddit.com/r/LineageOS/comments/af12lu/comment/edvwaex/) .

  1. As soon as the flash of recovery ends, quickly press Power + Vol+ + Bixby buttons altogether to directly reboot to recovery

→The quickly part should perhaps be highlighted, although of course best practise is to read the next step before committing to the current one.

  1. From recovery => Factory reset => Format Data/factory reset

  2. From recovery => Apply update => Apply from ADB => adb sideload <rom.zip> (iodéOS for S10 | iodéOS for S10e | iodéOS for S10+)

→ The first time I did this the transfer completed saying something like “Total xfer: 1.00x”, but I wasn’t following what the phone said, so I assumed it was fine. I booted the phone and gave up after half an hour.

I tried this part again and this time it got to something like “Total xfer: 1.76x” and the phone didn’t give any errors. The phone booted into Iode succesfully. What a relief!

Hopefully these can help someone avoid issues and know what to expect :slight_smile:

I succeeded in flashing iodé onto an S10, after much pain. The key change was to use Odin.

I’ve created normie-friendly instructions - where should they go? Is there someone in this community to tag, who deals with the website/instructions side of things?

That’s great! I wrote to iode support some time ago and got the response: “Installation instructions you can either report them on our community forum or directly to me and I will pass to the dev team.” Chose to do it here so that it can already serve someone :slight_smile:
