[Q] *HELP* My phone has bootloop - LG Optimus 4X HD

Hello everyone,
my phone has an bootloop after i removed some stock apps, i didnt think removing some stock apps could cause this...
the phone boots, and the screen handles the brightness and when i press the home button 2 secs it vibrates, but it doesnt show android itself, just he LG boot logo
can i fix this without flashing KDZ or Hard reset ?
cant get ADB, doesnt work
KDZ_FW_UPD.exe doesnt work for me (windows 8)
i will install an virtual PC and have the usb linked to that, will install windows XP on it.. see if it works

First try to turn off the phone, with the phone OFF, press "Vol-" + "Power button" until turn ON.
You should be in Android Recovery Menu, select "wipe data/ factory reset" and press "Power button", next screen go untill the middle and select "yes" and press "Power button". After that just reboot.
If everything went good should be enough, otherwise you need to re-flash.

The OP probably was asking for a way to regain control of his phone without the need to lose any personal data, as the factory reset will surely do. Unfortunately you are right, that is the last step before having to manually re-flash the original firmware and it's the only solution available to him now.
But a bit of advice, in case something similar happens again in the future. Just like with computers it's always advised to take a backup of your important files before tampering/tinkering with the software. And there are many ways right now to do this. We have CWM recovery (thanks to Dexter) which can be used for backup purpose, on the Play Store, there are also apps like Titanium Backup and the new Titanium Media Sync that can accomodate easily and simply all your backup needs. Although the present situation is a bitter pill to shallow, it will come to pass fortunately, so keep in mind the above tips to save yourself from grief and anguish in the future.:fingers-crossed: Best regards

well, im really lucky, yesterday i wanted to use deodex & remove stock apps script, and i made an backup in CWM first, as i havent removed it, and i went to bed, and in bed i started removing some stock apps, if i reflash the phone (hard reset wont work) will the internet storage be removed ? if it doesnt i can just restore the backup right?, then i will backup all the games and other data, and reflash 10G (maybe) or just 10f, as i have deodexed it at backup

If your backup was on the external sdcard, as its always suggested, I dont think it will be deleted, but for the sake of certainty remove the memory card prior to trying anything. If the backup is on the internal sdcard, then it will be deleted (I speak from personal experince since my phone also entered a bootloop and the only solution was to re-flash the official firmware) - quick and painless if you the guide correctly.

Yep, i had to reflash to fix, its working again, but the backup was removed i will get google drive and make a backup every week or so, and put it on google drive, does the stock backup backup everything ? or do i need to do a cwm backup?

If you want to backup a system image, then only CWM can help you. If you want to backup certain files/apps/settings there are a number of ways and programs to help you with that: LG's own backup offering, Titanium Media Sync, App Backup Pro, etc...

I installed "Battery Icon Mod v1.01", applied the mod, restarted, and I do see the AT&T screen, then I see the Galaxy moving screen, and after, I see the black screen, and nothing else, and I feel the phone vibrates (almost the same way, when the program crashes). I need to get back on the phone somehow, without restarting from scratch. Any way without loosing all of it?
Can you get into recovery with battery pull and up + down volume + power?
If so try reflashing or flashing a different battery mod and see if it works
VOL UP+VOL DWN+PWR does not work when battery is out.
VOL UP+VOL DWN+PWR works when battey is in
and i get the following choices
reboot system now
reinstall package
delete all user data
delete cache data
format internal sd-card

Looks like youre running stock recovery which = stock ROM. How did it even flash without failing verification? (not asking you, whoever else)
IMO you're hosed and need to odin back to completely stock (everything is lost) Unless someone else can think of a way to fix system files with stock recovery
I did flashed my phone with froyo 2.2 when I got the phone, and it was back in September or something. It was also rooted, so maybe that why it allowed to mod? I'm not too good with the phones and stuff, as i am more of a computer IT.

If you're really in IT you'd know that information is key to solving any problem. Stock 2.2 or a custom 2.2 ROM?
What I was trying to say, is I am not good with phones, and phone software and stuff
If you had usb debugging checked , you can use adb to push your original framework back to the phone. If you did a backup you can just install the backup. Otherwise your only recourse is to reflash the rom.
no i dont have any back and stuff. is there anyway to get the SMS? or my MEMO's?
You can flash a rom through odin...does not have to be stock...it will not wipe the info you have saved on your internal sd or external. if you sync your contacts with google gmail it will return all your contacts.
With that said, you will lose any programs you downloaded and installed unless you have them backed up (titianium back-up, etc).
It's not the end of the world, your phone will live again...
Just a thought...why not take this opportunity to flash one of the excellent custom roms in the development section?
This is why you will be backing up from now on...if no adb debugging then i dont this you can do adb pull or anything so .just flash another rom bud.we all make mistakes .yours isnt too big of a mistake tho. Sorry
Sent from my GT-I9000 using XDA Premium App
as long as I can keep my data, I'm not worried about loosing my applications, I can always reinstall them. I remember I tried to flash Froyo 2.2, and it took me forever to get it done. Could someone point me to a good ROM (preferably 1.2OC) where I can keep all my data.
Nope. You're pretty much out if luck with no backup. If you were on stock 2.2 then the reason you're in a bootloop is because you tried to install a mod to your framework that only works in deoxed roms.

what is this means then?
i guess the solution is to clear cache and factory reset ...
but u will loose ur data....
No roms will delete your internal SD card unless you do a master clear. Without pushing your framework back and having no backup all your data (SMS, memos, call logs) is gone. No way around it. Flashing with Odin still deletes your user data.
can somebody point me to the best 1.2GHz rom?
That's in the kernel. Which can be swapped out on any rom, I believe there is one for stock froyo.
Im kinda confused, I've been googling and searching this thread, and not sure what I have to do next. How do I began from scratch? What do I need to install the very first image? Where do I get it? I keep on searching all the threads this forum has, but its so much stuff here, that I get really confused.

[Q] Deleted every system file in system\App, anyway to fix it?

So today i was clearing out some stuff, after deleting all the apk files i downloaded.
i went to the system folder. i see this folder named App, i went in it, i see all these Apk files, so i thought they're just the file you use to install those applications. so i selected all, then deleted everything.
Then, a lot of things popped out, and this one wouldn't go away, it says Android.Phone stopped working. so i took my batteries out, and rebooted it. But it just shows the LG logo, then the loading, then starts over again.
I tried Volume Up + Power key, it just showed a the rest box thing, but after a bit, it just restarted the repeating process.
And i can't connect my phone to my computer because you have to set the USB mode on, while the phone is on.
ANY help?. Please. three year contract, and i have no clue what to do.

try the nvflash method to flash a stock ROM....by the way have you rooted your device?on custom ROM?have u a backup if you are rooted?
check in the dev thread if you bare rooted and want to flash the nvflash...
hope it helps
You seem to have root, because without you could not access the system folder. To get in the recovery menue you need to push and hold power + vol down(!) on your off-switched device. From there, restoring a nandroid-backup would be the easyest way. If you didnt made a backup, you can get back to a stock rom with smartflash and nvflash but you will loose your data.

I don't think he has CWM, Only a rooted device so it will be hard for him to get his /system back without any Backup...
Try NVFlash method or Smartflash, located in the Android Development section of this Forum.
I fail to understand why would someone be messing in the system folder without having a full backup

I have tried that, and got CWM now, i don't mind losing all my data, but. Is just that i've gotten an external SD card from one of my old phone, and i put a ROM on it. But I can't seem to find the External SD card anywhere on the phone. _ExternalSD has basically nothing in it. Anyway to get it?...
I rooted my phone before i deleted the system files. But does it matter now that I wiped everything?.....AHHHHHHHHHHHHH
OMG i fixed it, i mounted the USB, then put the ROM in the internal SD card, THANK YOU GUYS

Problem: com.android.systemui error

Hi! My friend has this phone, it's a little more than a year old, and exactly after midnight on New Year's Eve, this problem started occurring, so there's a possibility that it has to do something with date/clock. The phone is not usable, as soon as it boots, this error comes to screen and the only thing left to do is to remove the battery or press power button. He tried to reboot it many times, he tried to wipe cache, to remove SD and SIM cards, but no success. He also tried to enter Safe Mode but the same problem is present there as well. So it's not possible to delete apps or even to do a backup from the phone itself.
So what to do now? I know that there's always a solution with master reset, repair or reflashing the stock ROM but he wants to avoid doing that. Is there any way to solve this problem without reset? If not, is there any possibility to do a backup of contacts, SMS messages, apps, data and all other, for example via PC? I never had a Samsung phone so I don't know how it's tools work.
Thanks in advance!
Download Smart Connect on a PC, then connect the device using USB cable and then backup data. After doing this, boot into recovery mode(VOL UP+ POWER + HOME) and select wipe data.
Another possibility is to download a stock samsung rom and then flash it via odin. I know he don't want to do this but it is the fastest and easiest way. Normally data partition isn't wiped after flashing stock rom, but for safety he should make a backup, just in case.

PLS HELP! Phone NOT Booting UP after I made a BackUp using SafeStrap (TWRP v2.7.1.0)

First & Foremost, this is my first time posting on here. So my sincerest apologies if I shouldnt be posting here. I am also somewhat new at rooting so again, I'm sorry. I am going on over 48 hours trying to resolve this myself but to no avail....
My situation is...
I recently rooted my Note 3 N900A by downgrading to KK and then updated to Lollipop 5.0. I then wanted to play around and download some different custom roms and just do some exploring around with my new rooted phone as this was really the first time doing so (I'm sure people like myself (noob) are annoying to a lot of you experienced people!) ... but before doing so... I wanted to make a backup of my phone. So using SafeStrap (TWRP v2.7.1.0)... I did a complete backup of my phone. I included all the partitions that SafeStrap listed . So i backed up the DATA, CACHE, and SYSTEM. However, normally I would have saved the backup to an SD card.. but the only one I had currently in my possession was full. So... I saved the backup to my internal storage.. which im hoping wasnt my mistake in causing this problem i am dealing with... I just figured once i saved the backup to my internal storage.. I could then later.. go back and save it to my computer or another SDcard. So i saved the backup to my internal storage. Well, the backup completed... no errors appeared. Even said the backup was successful and for me to reboot. Which i did... but then it never actually booted up. It would shutdown... restart... the screen where it says Safestrap: Disabled... and then below that is... the picture of that crazy lookin dude on it.. and then on each of the bottom corners its says... Recovery (on the left) and on the right bottom side it says CONTINUE... and then i also believe it mentions something about how in 10 seconds the system would reboot if nothing was pressed. Well no matter what I press or DON'T press... either Safestrap would come back up if I press the left bottom button that says RECOVERY. Ya know.. the one where it has those 8 boxes that say, Boot Options, Install, Backup, Restore, Mount, Wipe, Advanced, and Reboot... or if I dont hit anything or if I hit the bottom right button that says CONTINUE... then the ANDROID RECOVERY MODE screen would appear. I mean i honestly don't know what to do. Now, i can navigate to the ADVANCED button in Safestrap and then File Manager and see the backup that I made in the TWRP file. But I dont know what else to do to get my phone to boot back up like it normally should. Please anyone that could help... words can't describe how appreciative i would be!!!
I'm not sure which custom ROM you wanted to flash but the n900a has a locked bootloader and can only be flashed with a custom ROM that is based on a stock ROM.

Question My Realme x7 max 5G stuck in recovery loop after uninstalling bloatare like glance, finshell pay, hot apps

like the title says I uninstalled the mentioned apps using adb and all of a sudden my camera stopped working so I decided for a simple restart and the device stuck in the loop ever since.
it restarts several times and open realme UI recovery and when I choose language it says " KINDLY REMINDER : system error, after select language, please select Online update(keep data) to recovery system, thanks! " .
So I did what the message said and I connect the wifi but instead of updating it says no updates found.
I also tried to wipe data but I got asked whether to retain contacts/media or format data.
I obviously tried the first one because I need the data but as expected it didn't work.
I am skeptical to clean format because I feel that I can still fix it with retaining the data.
I tried all the key combinations but only the realme UI recovery comes up . Please help me!
thank you
I don't think you'll be able to fix this without a full reflashing of the ROM using SP Tools and a format of the data partition from Recovery. You probably don't have access to full ADB now, if at all, and Fastboot won't help you recover anything. However, you should be able to rescue important files before you do this, as long as you have unlocked your bootloader.
Follow the steps here to install TWRP custom recovery. Once done, you can boot into it from fastboot by running `fastboot reboot recovery`. Once you're in TWRP, you can mount partitions so you can access them over USB from your PC.
Once you've got your important files transferred to your PC, take a full backup to be safe, then flash the stock ROM. This thread can help you do both of those things. Note that flashing the stock ROM using SP Tools will also restore the stock recovery. Once the process is done, boot right into fastboot and use it to reboot back into the stock recovery before letting it actually boot the ROM. Format your data partition (yes the whole thing). Now you can restart, and it should go through first time setup just fine.
I was going to uninstall these apps, but was too lazy. Guess lazyness is not too bad after all.

Unfortunately I had to go for the latter option of complete reset with the loss of data to get my device boot up . It seems the option to recover the device with data seems too complicated and not to mention the fact that this process is not without it's own risks. If you want an easy out from this issue I suggest that you complete format the device and have your important data backed up from now.
And Obviously I had data not backed up which I wanted on my device during this issue but it wasn't too important and I could let go of it cuz rest of my data was backed up.. but being the nerd I am, I tried to recover that data too.. but as I said it wasn't worth the time and risk for me so I chose the latter option.
Hope this helps! Do reply if you need further assistance !

for me the issue was like i just downgraded my device to the a.15 firmware after setting up i uninstalled the bloatware apps and some google apps which were not needed obviously and restarted my device and it got a bootloop, the issue of bootloop wasn't new to me i previoulsy had the same issue when i have downgraded to a.19 firmware. there is a simple fix, if you want to get rid of the bloatware apps now also you can use the disable command like.
(pm uninstall-user --user 0 ----package name---) this will not give any bootloop and can enjoy a part of RAM....
THIS WILL HELP
