[G2 Q&A, Help & Troubleshooting] Azyrael:
Hello,

I am having some problems since today i flashed the su binaries over my completely new lineageos install. (a14.4, fully wiped before).

it was stuck during boot at the android logo(let it boot for half an hour, multiple times, no progress). so naturally i wanted to boot to recovery, though it would not boot into recovery with any imaginable key combo.

so i went into bootloader mode (which, in my case, is jsut download mode, no fastboot whatsoever, and yes, i checked fastboot devices, (also adb), nothing to be found there)

next, knowing i had no other choide at that moment, i flashed a stock rom, via download mode. worked so far.

stock rom was running (ics), bootloader was still download mode only, and recovery was now stock android rec.

my next step was flashing a custom rom, since this was the most important thing to get to working then.

via adb sideload i fashed lineageos, once again. was working fine, so recovery next. but nothing worked.

included with lineageos is root access, so i enabled all the stuff, incl. adb, on my phone. but adb sideload always spit out errors (code 7 or 255) on rec install (twrp 2.8.something touch.zip) [some error about /tmp/update.zip] trying cwm resulted in the same thing, like did flashing gapps.

pushing the files to the internal memory (/sdcard) did not help, since 'flash from sdcard' resulted in an empty sdcard folder with no files to install (in recovery. in the file explorer while running the os, the files where there)

then i tried rashr (not sure exactly which app it was) to install rec. it said everything worked fine, trying to install cwm. so i rebooted

and nothing worked. the rom would not boot anymore (again, stuck at android logo) since the stock recovery only allows for adb access in form of sideload, no push whatsoever, and sideload did not let me install the os via zip, it was back to flashing a stock rom once again.

so i did that again (this time lolipop)

this is where i am now:

the rom boots perfectly, like does the kinda stock recovery, but again: no files in the sdcard path within the rec menu, though i pushed them there, and they appear there in the file manager.

i installed root, for those neat apps, that maybe one would work, but they need root and the stock rom does not know how to give those rights to apps, no option found for this whatsoever.

also, download mode is gone. (still no fastboot)

when i try to boot the bootloader, i just goes on to usual os boot (key combo and adb reboot bootloader result in the same thing)

recovery is still working, but pretty useless still. when i try to sideload a file, it quits with failed verification of the file. which is no surprise to me, since it shows the message halfway through the send process (observed from the adb terminal on my pc, never gets even close to 100% before the message appears on the phone which also cuts the connection therefore the file send process.)

i have absolutely no idea what the hell will get this working again. i dont really care about the download mode, but what i really need is a custom recovery to finally work, so i can install all of my stuff again.

does anyone have any idea on what i could try next?

hopefully yours,
