How long does the first boot take?

Hey guys,
i made a little mistake and dont have a nandroid backup nor a rom on my phone.
so, i made a factory reset and let it boot up, i want to know how long the boot takes at the first time after a complete full factory reset? (stucking at the LG logo currently and the LED is fading from blue into green)
Because im not even able to sideload with twrp, im getting this:
* cannot read 'sideload' *
thanks
Usually 5 to 10 minutes

Thanks but on the most non flex roms i dont have any luck to get it flash succesfull.
i waited like 15-20 mins after flashing but it just shows the LG logo.
the only non flex rom which is working is rayglobe (first boot takes like 3-4 mins)
What lg g2 do you have?

First time rooting

I rooted my note 3 for the first time with towel root. I have the latest safestrap. But when I go install my first rom. Phone goes into a reboot and shuts off for over 45 mind and does nothing except a blue light keeps blinking. Is this normal?

Dead Nexus

I have searched and searched everywhere and could not find an answer. I even posted my situation in the q&a section and it just got lost in the thread.
Ok so here goes, i was running multirom with stock as my primary, and the L port as secondary. Ran for months no issues ever. I was going to give the phone to my wife so i was gonna wipe the phone and put it back to factory fresh.
I had the phone booted (running secondary L port) and attemted to boot into recovery. The phone rebooted and got stuck at the google logo with the lock at the bottom. So i rebooted phone into bootloader(fastboot) and scrolled to recovery and was met with the same outcome. Then i rebooted once more to fastboot and scrolled to start ans same logo again. Even from a fully powered down device trying to start phone normally i get the same logo.
So i decided to just flash factory images since i was gonna anyways(twice actually)with wugs toolkit. I recieved zero errors both times but you guessed it same result.
I even tried another battery and still same BS. Last night i decided to flash a JB image manually so i could see changes in bootloader ie radio,bootloader ver,recovery etc. Now bear in mind in fastboot it would not reboot bootloader by selecting it so i would have to power off device and then use button combo to get back into fastboot to flash the next file. I continued untill everything was complete followed by rebooting to os and still same [email protected]$$$ng logo. Please someone help.

Flash the factory image in fastboot, don't use wugs. If it still doesn't work you have a hardware problem.

Boot into the stock recovery and do a factory reset.

Oneplus 2 bootloop after 3.0.2 update

Hello op2 was rooter, unrooted on su, installed os, rebooted and phone optimises as usual, and starts again endlessly... I have access to fastboot. When trying to go into recovery, all phone remains in boot logo... I had made a backup of my phone and left it on as card is there any way I can get it? Is there any way I can reactivate recovery without loosing everything? Your help would be greatly appreciated!!

I wasnt even rooted and did the OTA and ended up getting boot loop. Had to clear data for it to work.
They've changed the bootloader. So a modified TWRP is required. Flash Grarak's modified twrp via fastboot ---> https://www.androidfilehost.com/?fid=24572330218882108
Then Flash the Rom via Modified recovery. Full guide ---> http://forum.xda-developers.com/oneplus-2/general/zip-oxygenos-3-x-t3392826
could I be luck and not loose all.my data and backups left on the SD card if I used your options?

Wipe cache and dalvik cache in recovery. DO NOT WIPE ANY OTHER.

I can't get Into recovery or boot... power plus button down stays jammed at boot logo. How would I do this??

I can only get to flash boot button up and power... thats all!

Connect phone using fastboot & issue this command "fastboot continue". This should turn on the phone (if u restart u might end up in bootloop again), When it does go to developer options and enable "oem unlocking". Then try to unlock it. Then flash TWRP and any rom u like.

I need help!

Okay, so I went a long time without using my Nexus 10 (rooted, unlocked and custom recovery/ROM) and when I went back to use it again, it booted straight to recovery. Keep in mind that I have to keep it on charge, or the screen will stay flickering and it'll die. When I try to return to stock(via Nexus toolkit), it'll boot to bootloader via ADB, and won't fully not. As in it'll shut off, and if I try to power it back on, it shows the battery icon with the lightning bolt in the center. I've tried flashing a new ROM, and every time it fails. I don't know what to do guys. Is it done?
