iPhone6S turn to black screen, after trying to run uicache with doubleH3lix

[liuxuan30]

Hi there,

Good work here! I'm sorry to report an issue that, I just jailbreak my 6S yesterday, all went well, till today's morning I found Cydia crash, so I suspect my phone rebooted last night.

Then I open h3lix and seeing it says "run uicache". I paused one second and clicked run. Then my phone turn to black screen. After a while, it still does not come back so I did a force restart with holding home buttton and sleep button.

Then my phone goes into "apple logo" -> black screen loop. I tried to force restart several times and wait. Still the same symptom.

I'm not sure if my phone can recover again, but I need to raise this issue to see if any possible solution before I flush it with 11.2.6... Thanks.

Hi! Did you already flush it?

If not, my question is did you install an SSH client?

I could ssh, I remember it's dropbear. I didn't flush yet, as no obvious reason to flush to a version without jb.

There are a few solutions I can think of:

a) Follow this guide to restore phone without upgrading iOS: https://www.reddit.com/r/jailbreak/comments/5rxsgo/tutorial_a_fix_for_those_of_you_stuck_in_a_boot/

b) Try this comment at the top if SSH works: https://www.reddit.com/r/jailbreak/comments/1gr42y/help_iphone_boot_loop_i_fd_up/camzdo1/

c) Unlikely to help unless you can reboot into a nonjailbroken mode: https://www.reddit.com/r/jailbreak/comments/4uylk4/tutorial_installed_activator_got_a_bootloop_heres/

my iphone is totally black screen after boot, seems like turned off already, nor can ssh or I can see the phone on mac, so none of it works. sorry.

That's unfortunate. :(

There's nothing else I can think of other than restoring. You could see if you have backed up to iTunes at some point and try restoring from there.
