FIX ANDROID BOOT LOOP ISSUES ON STOCK ANDROID
Step 1. Remove the battery from the device and wait for 30 seconds and then put the battery again on your device. If your phone doesn’t has the remove bale battery like Nexus 4, then power down the phone and keep it powered off for 5 minutes. This will turn off your device permanently.
Step 2. After that Boot your device in to Recovey Mode. Samsung Users use Volume Up+ Home + Power keys. If you have the other Android device then do a Google search how to enter in recovery mode.
Step 3. Once your android device is in Recovery Mode, Go to the “wipe cache partition” option and select it.
Step 4. After that go back to the recovery main menu and reboot the device by “reboot system now” option.
Step 5. If the device again stuck on Android Boot Loop pull out the battery again and repeat the above steps. This time also “wipe data/factory reset” and then reboot device.
Now your device will come out of the Android Boot Loop and at the first time the device will take some time to reboot.
FIX ANDROID BOOT LOOP ISSUES ON ROOTED WITH CWM RECOVERY ANDROID
Step 1. Follow the Above guide (Fix Android Boot loop issues on Stock Android) Step 1 and Step 2 on your device.

Have you considered rooting your phone?
See you have to do it step by step
First format dalvik-cache
Then wipe cache partition
Then factory data reset and then boot it normally
If it takes more than 15 min then tell me
And see to it if your mobiles try to read the app I mean optimize them.

No it isn't possible. Every phone has a recovery either a stock once or a custom. Without recovery the photo isn't possible to be operated even.

I have Galaxy S3 on which I have CyanogenMod. I was on vacation in Poland last summer and I got there my Rogers Galaxy S3 phone unlocked and polish language CyanogenMod ver 10.0 was installed . It worked fine since. Recently, I installed few game for my grandson. Right after I found that it took longer time to boot a phone. Then I started to get a message after rebooting, "System process didn't start" with option to click "Wait" or "OK". When I clicked OK phone was slowly booting and finally was fully operational. Every new reboot took longer and longer with the same message, "system process didn't start" click "wait" or "ok".
Finally it stopped to boot. When I power on a phone it starts booting and get to same message as before. I click "wait" and nothing happen, or I click "ok" and still nothing happen. Then phone reboots itself and keep doing it.... Doesn't boot anymore to application.
What I can try to do to fix it? I am pretty new to this "rooting" "Odin'...etc so if you have an advice please communicate it as simply ans possible.
Any help appreciated
Thank you
Boot into recovery and flash a newversion or same version of CM 10 or CM10.1 (Either one is good or you could pick a whole new ROM up to you). Make sure you follow the instruction of the ROMs thread for how to install. To get to recovery you hold the volume up + home button + power untill it boots to recovery and from there follow ROM instructions.

Before you install any ROM be sure to do a factory/reset, wipe dalvik cache, wipe cache partition and format system, and don't worry about doing everything twice, especially if you are coming from a TW ROM and going to a CM type ROM. If you don't start off with a clean slate you may have some "ghosts" left over.

2. Go here -> http://forum.xda-developers.com/showthread.php?t=1722686 -> download ODIN.. and READ THE INSTRUCTIONS!!!
3. Use ODIN to put the STOCK ROM back onto your phone. It takes a little while to do it.. and first boot can take a while as well.
4. Go here -> http://autoroot.chainfire.eu/#odin -> download the correct version of CF autoroot for your phone
5. Use ODIN to install CF auto root the same way you installed the STOCK ROM
6. Go to the google play store and download ROM manager

8-> enjoy a rooted phone and flash custom roms if you like!
Hello, I made a very foolish decision today. I just recently rooted my phone (i747), and i am still not familiar with roms or flashing or any of that. I installed the Rom Manage app by clockworkmod onto my phone. I did no other preperation other than creating a backup through that app on my phone. Then using that app, i downloaded the CyanogenMod 10.1, directly onto my phone. It then gave me the option to wipe data which i chose not to do. It then started the installation of the rom. Everything started off okay and it looked like it installed. When it rebooted it got stuck on the CyanogenMod circle boot and no matter what i try i cannot fix it.
I cannot stress this enough. I am very new to this stuff and am not exactly sure how everything works. It is my mistake and i understand it was the outcome of my stupidity. However, all I am trying to do is fix my phone. When i try to boot into recovery mode (power, home, and up vol) it just restarts still in the boot logo. Whenever i press power, home, and volume down it says "booting a custom rom can harm your device are you sure?" but whether i choose yes or no it is still stuck.
Sorry about all the text, but can somebody please explain to me in the most noob friendly way possible how i can just get my phone in working condition? Thanks for your time
Try booting into recovery this way, in this button pressing order: Vol up + home + power. When your phone vibrates and you see the blue text in the top left corner of the screen, release just the power button.
If this gets you into recovery, you can wipe data, cache and dalvik (under advanced) to see if this clears your issue.
For future reference, don't flash ROMs in rom manager. Only use that app to update or install recovery.
Thanks, that got me into recovery mode. I wiped the dalvic cache, and did a factory reset, but I am still stuck in the boot

I would suggest to download the CM10 ROM from their thread, and copy it to an external sd card. You can reflash it from the sd card in the recovery menu.
ya, now that you know how to successfully get into recovery, i would flash a rom and gapps again via that route. check out the link in my signature. its got some stuff to look over for a safe and smooth backup & installation
Thanks!

maybe you tried to make an advanced data wipe and selected internal storage, dalvic, cache, etc.
what you need to do is put the phone in recovery mode again, select install and then scroll down to find the OS zip that was broke when wiping, after flashing be sucessful reboot system. then turn off the phone again o get it in recovy once more, select install, scroll down but this time you must to install Gapps. to conclude you need to flash OS and Gapps again through recovery mode.
hope this help

Great question chuko. I had a soft boot loop too. I did a full wipe including the dalvik, system, and cache then flashed ROM again. Also try taking out your battery for about twenty seconds then let it boot up. Just let the boot loop do its thing for about five minutes and see if it corrects itself.

Can U be more elaborative on the procedure u have followed as u r unable to post the ink. If u have used Odin to flash the ROM I suggest you to repeat the process as a last resort. Before doing that try the following:-
1. Once the Odin gives u the message Passed! phone will reboot automatically, If u have checked Auto-reboot option then Samsung Boot Animation appears, Now remove the battery, wait at least 10-15 seconds before re-inserting the Battery back.
2. Now go into the recovery mode and select 'Wipe data/Factory Reset'
3. Then Wipe Cache. ---> Then Go to advanced and Select 'Wipe Dalvik Cache" --> Now Select Reboot into Recovery Option.
4. Now select 'Reboot System Now' option.
5. It will take some time, wait at-least 10-15 mins minimum.
If the phone doesn't boot-up re-flash and report in the forum.
All the best.
I followed the instructions given ia a tutorial from androidxda to downgrade my phone. if you google it you will find iti very easily. I used odin 3.09 to do it and the stock rom 4.1.2 for my phone and my country given from xda. When odin gives me the PASSED sign the phone tries to reboot and gets stuck in boot loop. The phone is not rooted. I tried removing the battery and wiping cache, it didn't work. Then i tried removing the battery once again and do a hard reset ( wipe data/factory reset) it didn't work either. I did all the above several times and then i tried flashing the rom again with odin. It didn't work.

I hope u have followed the procedure given in the above link. It's very good and worked for me. If u r confident that the firmware which u possess is without any errors (Note: errors may occur while downloading & parsing the package as the download file size is HUGE). Reflash.
Yes, i followed the procedure given in the link you posted above step by step...I flashed the rom once again using stock rom from sammobile for my model and country. The phone is still stuck in boot screen...

The phone IS NOT rooted. There is no wipe Dalvik cache option. There is wipe cache partition and it doesn't work (4.2.2). When i try to whipe cache partition the phone reboots on its own without performing the action. Factory reset option works, the phone returns to recovery menu, i select reboot and i get stuck in boot screen again
I've followed youtube videos and other sites to enter recovery mode but all i get is an option to factory reset or to exit. I've held down the volume down and power key together until the LG logo appears and then let go of the power key after a second.
What am I doing wrong?

What android version are you running? And how did you install the recovery img? And which one? If you installed the recovery properly and want to enter via hardware buttons it's the correct procedure.
--> If you're in the LG Stock recovery (where it asks you if you want to wipe your phone) just click yes twice and you'll boot into TWRP or clockworkmod (Whatever you've installed). I know that's a dumb way but it works
Note: If you didn't install the recovery correctly you will then wipe your phone!!!
To find out if you've done everything correctly with your recovery (and if you're rooted) just use the app Quick Boot from the play store, grant permissions and reboot into recovery. If you've done everything correctly you will be in recovery mode then And you can be sure that everything is setup correctly and use the hardware button method to access recovery (Just like I told you).

Nope and yes - There's only the option to factory reset if you don't have a custom recovery installed. Sorry to bear the bad news I thought you had a custom Recovery installed and don't know how to enter it. There's no stock-like recovery to access on the G4. Sorry :crying:

does this work on stock MM 20A or 20B without unlocking bootloader. i'd do it even if its just temporary to wipe cache and return to stock recovery after the wipe. factory reset just is too much to start from scratch with installs and setups. i am Never Buying a LG phone ever. it was my mistake
I have an unlocked bootloader, twrp (2.8.7), root and on MM V20a, Stock.
I can boot into revocery via adb reboot bootloader / fastboot recovery boot twrp, all works fine (excecpt that I cant access the external exfat sd card with cm12/cm13 based roms).
But I cant boot with Power on /Vol down keys intoTWRP recovery.
Altough I can boot in LG factory reset menu but if I perform that it wipe indeed to facotory reset no way to reboot in recovery.
I try it a couple of time without success. Also I try differnt key combinations (Power on / Vol Up + Vol down etc.), around 15 times.
Also I cant use tools like "Quick Boot" I try 4 or 5 diverents the result is always the same - android on the back with open hatch.
When I try to boot on CM12/CM13 via Power Menu directly to recovery the same effect occurs.
Whats gos wrong? Where is my mistake?
If you flashed TWRP, the "LG Factory Reset" menu will still show up. Just confirm 2 times with yes there, and TWRP will get started . Bit confusing, I know.

Nope and yes - There's only the option to factory reset if you don't have a custom recovery installed. Sorry to bear the bad news I thought you had a custom Recovery installed and don't know how to enter it. There's no stock-like recovery to access on the G4. Sorry :crying:

Click to collapse
