It’s been a while since I tried to install a custom ROM on any device, so I probably should not have jumped back in right into Lineage 16 on my nexus 9, but I gave it a shot and I’m a bit stuck now
I flashed the ROM and on the first boot I got the “To start android, enter your password” screen. I saw people were saying type in “deafault_password” to get through this, but the system was freezing after a few seconds. The next solution I saw was to Format Data using TWRP.
Now when I boot, the system freezes as shown in the attached image.
Now when I return to TWRP I get a “Mount Decrypt Data” “Enter Password” screen. I’ve been hitting cancel and I have tried formating the data again in TWRP, but that doesn’t help.
I thought I might sideload a different custom OS, but ADB sideload also isn’t registering.
Any thoughts? Thanks.
Edit: I was able to go down to lineage os 15. Wanted to delete this post but can’t see that option. Thanks.August 16, 2018 at 9:11 PM #44405
Just tried this ROM ( from flounder 15.1 ) and it reports ERROR 7 while installing.
ThanksAugust 17, 2018 at 2:52 AM #44472August 17, 2018 at 11:47 AM #44483
Its TWRP 3.0.2-1 and I assume it is official, I just downloaded it from the TWRP list and was the latest at the time about a year ago. I have installed most Lineage 15.1 ROMs with it.
After wiping all but “Internal Storage”, I then proceed to install the ROM and get ERROR 7 within a few seconds.
ThanksAugust 17, 2018 at 11:54 AM #44484August 17, 2018 at 1:59 PM #44513
Now using flounder TWRP 3.2.3-0 and the ROM loaded and I rebooted.
After displaying the Lineage boot up sequence.. (3 circles)
I am presented with a screen saying “To start Android, enter your password”
and a keyboard, but then everything is locked up. I do not have a password !!!
(Have not loaded any GAPPs as yet)
Edit: After two ‘Factory Reset’s the keyboard was responsive for a few seconds, I managed to type in a random password, but then am told unsuccessful and need to do a factory reset and it all repeats. If I do not type anything in first second the keyboard locks up. The Nexus make a thumping sound once or twice just after boot up.August 17, 2018 at 6:59 PM #44606Timi FadiranMember
The same thing happened to me. It would give me a few seconds to type then freeze. I saw people saying type in “deafault_password” to get through this, but the system was freezing after a few seconds.
The next solution I saw was to Format Data using TWRP. That got me past the password screen, but the device would freeze on the home screen shown in my original post. Also, at this point when I would return to recovery I would see a “Mount Decrypt Data” “Enter Password” screen. I would hit cancel and try formatting a few more times.
The next thing I tried was flashing the rom rebooting into recovery and then flashing gapps before the first boot. This seemed to stop the freezing, but then I got an a continuous error that pixel set up had crashed. At this point I gave up and installed Lineage 15.1 instead.August 17, 2018 at 7:31 PM #44607
Thanks at least the problems are consistent, I saw your first post and hence tried the password but only got to ‘f’. Maybe we should wait for next tip from shibaa987.August 18, 2018 at 2:58 PM #44713
Found this which gets rid of the password screen and Nexus fully boots up but is unresponsive to touch screen so is in effect locked up. Only Power off button works
Boot into Twrp and under Wipe you’ll find FORMAT DATA, not wipe data.. Format the data and the rom will boot . Note that you’ll lose everything from you phone, so it’s good to save files on pc before, if you have something important..
update — after further ‘hacking’ I now have a Nexus with only TWRP on it…… :-((((
