LG Optimus G Pro Security Error/device not being recognized by windows

After attempting to flash the cyanogenmod rom to my LG Optimus G, I ended up with the "Security Error" screen whenever I attempt boot. I can enter download and hard reset modes, but not recovery mode.

I've done a significant amount of searching around and attempted a few stock recovery methods that don't seem to work. I am thinking that the problem lies in windows not recognizing my phone as an android device. So, it makes the mounted device sound, but when I am in device manager, I cannot find the device anywhere, and when using adb to detect devices, it does not come up, despite the most current drivers being loaded.

Help? I would like to get my phone back if possible. I apologize if this answer is somewhere, but like I said, everything I have tried seems to fail.

Thank you so much in advance!

Try uninstalling your adb drivers for your device then reinstall them. Also if you didn't have usb debug mode on then you wouldn't be recognized, if this is the case and you can't get back into your system and you are unable to turn it on or verify that its already on then youll probably have to go back to complete stock firmware for your devices model number. It seems from what you are saying though that your drivers aren't working right, try getting them installed correctly or update them. When you connect your device to your pc normally does it show when you click on computer, can you see it and its files through windows explorer? Does it show as a media device or as an adb interface? You can try using different usb ports on your PC also, and make sure you are using your stock usb cable.

If you can verify that your drivers are installed correctly but still isn't recognized, then since you can get into download mode you should be able to restore your stock firmware.

Are you sure you used something made specifically for your device model? Did you install a stock kitkat update or did you try installing a custom ROM? If you used something custom then were you rooted and have custom recovery installed before you flashed the upgrade? If you were still on stock firmware and recovery and tried a custom ROM then you are bricked, custom must be flashed on a rooted device with custom recovery, not stock, only stock updates can be used on an all stock device. If you can't get to fastboot or any other mode then your phone is dead and youll have to replace it, there's no saving it if it won't do anything at all.

Can't understand why phone is bootlooping.

Hi..

Before I start explaining my problem, I'll tell you the basics of my phone. It's an iNew i4000S (the 's' is important.). It's a chinese phone... obviously... And Octa-core MT6592. Oh and i rooted the prick.

Okay, the last thing I did before it went into bootloop was download and install a custom font. I used a font installer by JRummy apps or something. (the installer comes in the ROM Toolbox. The one with the yellow bird fella). The font I used, was a custom/thirdparty font or whatever. Basically, I downloaded a font from CoolText that didn't come on the app.

(CoolText is a website, and the font is under: Font > Science-fiction > Sci Fied 2002)

This is the last thing I did before my phone threw a hissy fit. It's a font like... This shouldn't cause a bootloop..?

(Earlier that day, I deleted my browser app (the .apk and .odex files). But I had chrome, so I thought one less browser wouldn't cause a problem.)

There's no stock ROM available for the i4000S (yes, the 's' is important). And i've tried flashing an official firmware upgrade using SP Flash Tools. (This won't actually work as SP says my phone is an MT6589T. When it's actually an mt6592.) I have adb drivers installed and mtk droid tools. So if anyone has any ideas on what I can do to get my phone out of bootloop, I'd be very happy to try them.

P.S:

I have tried the normal bootloop problem fixes. (Custom ROM bootloop, Permission mess-ups, etc.) But, they haven't worked, as the reason my phone decided to bootloop is beyond me.

(Also, I don't have CWM recovery or TWRP. I do have a ClockworkMod backup, which i tried flashing. It didn't work..)

I'm sure you can tell I'm new to rooting.. but I'm not here to be laughed at by some judgmental muppet. If you have a suggestion, suggest it. Thanks :)

There's no need for all of those wipes. Factory reset wipes cache, dalvik, and data.

---------- Post added at 12:35 PM ---------- Previous post was at 12:21 PM ----------

I had the same problem a couple of years ago installing a font using the same app. Just restore the backup that you made before messing with your /system, or the whatever is the most recent one you have.

EDIT: I see you tried that. How did you try flashing the backup? You need to restore that in recovery, which is hard to do when you don't have that recovery installed. Flash CWM in recovery, then restore your backup. And ALWAYS make a backup before screwing with anything that modifies your system partition. You'll need TWRP or CWM installed to do that.

Ill be back with a link and instructions for installing custom recovery and how to flash a ROM.

If you don't have a developers edition of your phone and you bought yours retail then you've got a locked bootloader and will have to unlock it before you can install a custom recovery

I'll post a link for unlocking your boot loader if it exists.

Ok, with this link you may not have to unlock your bootloader for custom recovery, I would double check first if I were you, if you're good on the bootloader then this will be easy for you

Xolo q500 softbricked

Can Anyone Help me. My Xolo Q500 is softbricked. It is niether booting normally nor booting to recovery menu. I have tried sp flash tools but the stock rom of my phone which i downloaded does not contain any scatter file, probably because it is a Qualcomm based device. Please help me..................
[General Questions and Answers] Droidriven:
I looked everywhere for smoething for your phone, all I ever found was the stock 4.1.1 and 4.4.2., did you try both through sp flashtools or find your stock recovery somewhere flash it then download the factory stock ROM official update and try flashing it through stock recovery if you can find yhe stock recovery, I've looked everywhere for you and thats all I'm finding, I looked for well over an hour and I dug pretty deep so I'm thinking that's going to be your best bet.

That is the only restore or unbrick method I found regardless of your chipset after all my searching, good luck.

If you go through ALL of it, pick through every page, link and section, you will see that everything you want to know is in there somewhere, you just have to read through and see where you want to start. You can do things like porting ROMs, making your own custom recoveries, compiling your own kernels from source, building ROMs from source, compiling/building apps. Pretty much any part of the android environment you can think of. That's where you'll have to start, not many people have the kind of time to walk you through something like that, follow the links at XDA and you'll learn what you want to know.

[General Questions and Answers] freestilesteve:
How about this one for you guys. Kinguser or superSU? (Do I need to replace Kinguser)

Whats up guys?? I can't really find out how to do this right or even if I need to but I thought I'd ask.

I rooted my RCA RCT6203W46 10.1 tablet on Android kitkat 4.4.2 using king root 3.3.1. It seemed to have rooted fine and I get that it did after using root checker. It installed kinguser(english) which gave all my apps permissions that need them, and everything seems to be working okay, except that titanium backup says that its su is "Unknown" and that it would be better if I could switch over to superSU binaries or su or something to that effect. I'm not sure exactly how to do that. I tried a tutorial here that is how to remove chinese vroot from xolo phones or something that had you copy the superuser.apk and change permissions with es file explorer, but that didn't seem to work. I gave up after trying to update the superSU binaries which kept failing to update, and even after reboots I still couldn't get them installed or updated. I think I removed something that caused me to bootloop but fortunately I was able to recover from it and everythings fine now. So in the end I'm just wondering if I need/should remove kinguser and the right way to do it? I've seen where people say download superSU from the playstore, give it permissions then erase kinguser or something like that . I gave superSU permissions from kinguser but was never able to get far enough in superSU to remove king user (which I'm thinking has something to do with the binaries from superSU not being able to update/instal whatever they gotta do). I imagine if these binaries are able to update or install or do whatever they gotta do correctly then superSU can get full permissions so I can remove kinguser? Or do I remove king user before superSU gets permissions and go from there? Or should I just leave it as is and not worry about it? Just not sure what to do.

I believe you leave kinguser alone, install superSU or superuser then go through kingusers options and choose its full unroot and remove option then update superuser or superSU binaries, I think that once you install su or superSU and get rid of kinguser you can update the su or superSU binaries by flashing the su or superSU zip through recovery and uoull be good to go.

---------- Post added at 03:12 PM ---------- Previous post was at 03:07 PM ----------

Try extracting the stock camera apk from your ROM or another if you can find one then push it to system app folder before installing it, you'll have to change your permissions in file explorer to move it to system, or you can use something like Titanium Backup to convert it to a system app. Try this with a stock camera apk for your device or any camera if you can't find stock.

Thanks N_psycho_PD_uh?

Thanks for the response. I might have to try it this way and see wats up. I do have a question though/concern.

Wont doing that in Kinguser remove my root?? So would I have to reroot with kingroot again??

Also I know how to flash images but how do I flash SU? Is there a certain img for my tab or can I use the latest one?? I think I did it this way and it put me in a bootloop so I dont know whats up. I guess I can try again and pay more attention this time, but not sure if this is going to work. I never flashed the img but I tried removing kinguser like u said with no success which was what I think put me in a bootloop which might have been caused by not installing the binaries correctly in su. I am going to try this way again though. Can you elaborate how to flash a SU right? Or which su, or how I should flash su? Can it be any su zip/image or does it have to be a particular one for my tablet/android version? Can I use rashr flash tool app like I did to flash twrp? Or would I flash su while in TWRP recovery? Just not sure how to exactly do that. Other then that I think I understand everything else.
[General Questions and Answers] Droidriven:
You may lose root but that is why you make sure you have the latest superSU zip (it must be a zip file to flash through recovery), you can use any custom recovery of your choice, just boot to recovery and flash the zip and you'll will have root again.

If you read the help thread, another user had this kinguser/superSU problem a few days ago, I don't remember their username or how many days ago that it was but if you read back you'll find it.
[General Questions and Answers] freestilesteve:
Thanks.

Cool. So as long as I have the latest superSU zip which I assume I can get from the superSu website right? I can flash through recovery and I should be good to go? Thats after doing the previous steps you mentioned to remove kinguser? Sounds like a plan to me. Hopefully it will work this time. I was thinking image because when I flashed the twrp file it was titled recovery.img. So that superSU file is a zip? I think I'm almost there. Now just gotta find this superSU zip.

P.S I think I found it here http://download.chainfire.eu/695/SuperSU/UPDATE-SuperSU-v2.45.zip. Do I just flash and go?? I don't have to rename the zip file are anything?? Getting closer and closer. lol!! :)
[General Questions and Answers] Droidriven:
If you want ill post a link for the superSU zip for you. Let me say that I don't know your device or kinguser but anytime I've lost root on my devices flashing superSU zip through recovery has always been the fix, it would be better if you checked this issue with other users of your device. Ill be back with your link.

Here is the page for superSU, click the link that says CWM/TWRP/Odin flashable zip

http://xdaforums.com/showthread.php?t=1538053

Download the zip and put in the root of extsd and boot to recovery and flash the zip the same way you would a ROM, don't wipe data/factory reset in recovery but you will need to wipe cache and wipe dalvik cache before and after you flash the zip just to be sure, the wipe before is all that's necessary but the wipe after just ensures that it takes, then reboot. If you still get a bootloop then there is a link on the page I gave you that discusses installation issues that you can follow to troubleshoot your difficulty.

---------- Post added at 05:38 PM ---------- Previous post was at 05:35 PM ----------

I see that you already found the link for superSU, yes that is the one you want, flash that through recovery and you should be good but I think kinguser must be gone first or it may cause conflict.
