LG G4 stuck on Android is starting

[Papote13]

Every time I reboot my LG G4 I get the Android is starting. Optimizing app 1 of 1... and takes about 15 minutes to finish each time.
I've tried booting into recovery mode to wipe the partition cache, but the phone won't seem to boot into recovery mode by Holding the Power button and volume down buttons on boot. It ignores it.
Tried deleting the cached Data from the Internal Storage settings.
I've also tried using the adb reboot bootloader command but it just reboots as usual with the only difference is that it displays a message saying: "Select enable OEM in the settings". I enabled the OEM and went into fastboot, but get the following:
>fastboot erase cache
******** Did you mean to fastboot format this ext4 partition?
erasing 'cache'...
FAILED (remote: not supported in locked device)

I have never rooted this phone and really don't want to flash it.

My damn LG G4 has been doing the same thing for the last month. I even FDR'ed it a week ago or so; this initially seemed to fix the issue but now it is doing it again. So ****ing annoying.

In order to get to the system recovery mode, hold down the power and volume down button until the LG logo appears, then release the buttons for 1 second and then press and hold them down again. Continue holding them down until the recovery mode screen shows up. On my phone, I had to wait for it to cycle through the LG logo screen twice, but after the second time the LG logo screen appeared, it went to recovery mode. Hope this helps.

can't get into recovery. just goes to android is starting ...... for 15 mins. Just came back from LG "refurb". Last time I buy this junk. This phone has been back to them 3 times since I've owned it for the same bootloop issue. 2x in the last month.

I'm the idiot this time. After configuring as Developer, I toggled Developer and Developer/OEM unlock and Developer/USB and got the RSA question.
That fixed the issue. Then I got TWRP loaded. https://forum.xda-developers.com/g4/help/refurbed-bootlooping-t3776566

Zedge was the culprit for me.

I had the same problem and I uninstalled Zedge and boom fixed instantly.

THANK YOU! I was going through a gigantic list of solutions for the last week and nothing was fixing it. Read your post tonight, uninstalled Zedge, hit reset and the problem went away. :good:

Thanks mate, my missus phone had this issue. Uninstalled Zedge and it starts normally now.

Problem resolved

I've had the same problem optimizing app 1 of 1 Android is starting. Happens every time I reboot or change the battery in my LG G4. Has been going on for a couple months then suddenly this morning it stopped. This was after about a half a dozen apps updated on the Play Store. I will add a screenshot but I suspect it was the YouMail app or possibly Google. I had tried uninstalling you mail but the problem persisted. I was told by an AT&T Advanced Tech that I needed my firmware flashed but AT&T can't do it and BestBuy can't do it and I have no idea where I can get it flashed. If it happens again I'm going to try flashing myself on my PC. Good luck.

I have the same problem and i dont have any of the apps listed in the web. It even does it in safe mode. Does anyone knows what to do? I already factory reseted my phone. And i cannot enter in recovery mode.

Zedge

Thank you for that tip. I've been having this annoying issue for a week. Just uninstalled and the problem problem has gone. I was gradually uninstalling apps to see which one was causing it but would have taken a month to get to Zedge. :laugh:
Grateful thanks

Same issue. LG G4, not rooted.

Not rooted, no zedge, no true caller. No clue what it is. :crying:

I had the same problem. For me Osmand and Deezer caused it.
Here is the method to figure out which app(s) the guilty:

Can you walk me through exactly what you did? I'm having the same issue and I'm about to throw this phone through a wall. I'm by no means a phone tech.

Resolution du problème de demarrage de LG G4 : Optimizing app 1 of 1...

Sorry i am not well in english. So i reply you in french :angel:
J'ai eu le même problème avec mon LG G4
La source de ton problème serai tune application que tu as récemment installé. Chez moi c'était une application météo qui était la cause.
Comme solution :
Essaie de désinstaller la plupart de tes applications. Une fois faites, redémarre ton téléphone. Tu verras que le problème (Optimizing app 1 of 1...) sera résolu. Maintenant tu dois identifier l'application qui cause le problème et ne plus l'installer :good:
