Hi all,
Would appreciate some guidance please.
I was preparing my phone to flash a custom ROM. In the process I wiped the data, wiped the cache, wiped the delvik cache, and accidently wiped the external SD card. So basically everything has been wiped.
Now my phone will not boot past the "Galaxy S 4" screen and will not boot into recovery mode either. When I press and hold the "volume down + home key + power key" to get into the download custom OS screen, that gets stuck at "Downloading...Do not turn off target."
When plugged into my computer, the USB won't open the external SD card.
What options do I have at this point?
Thank you in advance.
So I've wiped the Dalvik Cache, Data, Internal Storage, and System, but I forgot to flash before rebooting. Now it's stuck in the WARNING BOOTLOADER UNLOCKED screen and everytime I tried resetting to recovery mode it would turn off then turn back on at the same screen. ADB is not detecting the devices also. Is there anything I can do or is it bricked?

Boot into bootloader by holding down vol down and power together. The timing can be a little tricky when it is stuck or looping. Hold power until the screen goes dark and it tries to reboot, usually about 8 seconds. Then let go and immediately hit vol down + power together. Hold them until the bootloader screen comes up, should be pretty fast. Might take a few tries to get the technique down with it bootlooping.
From there you can flash firmware directly with fastboot, or boot it into TWRP to flash something from recovery. If TWRP fails to boot for some reason then fastboot flash it again.
It should not be a brick just from wiping everything. Well, just a soft brick anyway.
Thanks!
I was able to get into recovery!!
Last night I wanted to wipe my cache partition, however when the screen comes up wasnt in recovery mode,therefore I pressed start, and I leave it to boot up. When I come back, it doesnt boot up, after 10 minutes. What should I do without losing any data from my phone? Will perform a wipe data/factory reset wipe all items in my internal storage?
I have installed nuclearom 6. the problem started after i got fingerprint hardware not found error. Suddenly the phone got into bootloop. The phone shows 'zuk' and 'powered by android ', followed by 'radioactive kernel' screen. I cant turn off the phone unless it runs out out of battery. I can go into twrp recovery, however the phone reboots automatically after 5-6 seconds in recovery. The same with fastboot also.
I have tried wiping delvik cache, cache, system (yes the os) and data.
Npthing worked. Please help.
Hope this can help https://forum.xda-developers.com/zuk-z1/help/z1-bugs-t3666821
LS997 (September 2016 security patch), got to the end of root and couldn't reboot into TWRP recovery. The device is recognized in ADB while in fastboot but when I'm at the secure startup it's unrecognized, like USB debugging is disabled.

If you've hit secure startup the phone has likely booted into regular Android far enough to replace twrp with stock recovery. Reboot into fastboot and reflash twrp (you can use the newest twrp if you want). Once done flashing unplug from PC and pull the battery. Reinsert the battery then boot into twrp via the factory reset/volume button method: hold volume down, press power until the screen turns on then (still holding vol - ) tap power repeatedly until a prompt to factory reset appears. Approving it twice boots twrp if it's installed, otherwise stock recovery will do the reset.
Once in twrp go to wipe, then format data (type yes to confirm), then go to reboot, then recovery. Once twrp restarts flash your choice of magisk/supersu.
Once one of those two is installed it makes it so twrp won't be replaced.

Did this, got to the set-up screen (languages, accessibility) and an error ¨com.android.phone has stopped¨ spammed the screen. I tap ¨stop app¨ and the pop-up comes back immediately.
I tried to fix it by factory resetting (in the settings, NOT using the volume down/power button menu OR TWRP) and now I´m stuck in TWRP. Every time I try to reboot to System, it boots to TWRP now.

Power down, then boot to twrp using the volume buttons. Use the wipe menu there to do the reset.

Wiped it, still get the com.android.phone errors.
Unfortunate, makes doing anything impossible with so many error popups.

Reflash your variant's official KDZ using [PARTITION DL] with patched LGUP leaving [aboot], [abootbak], [recovery], [recoverybak] partitions unchecked.
- Once the flash finishes & phone reboots, do a battery pull so phone doesn't fully boot (wiping recovery & encrypting data)
- Insert battery again
- While pressing volume down button - reinsert usb cable so it boots into fastboot mode.
- Follow dirtysanta guide for your variant from running step3.bat onwoards (which flashes TWRP back into your otherwise stock phone).
LS997, no official KDZ. Use VS995, but dump everything with LGUP (bar userdata) before hand
