[Q] My phone is dead on stock...(due to rooting/unlocked failure?) Please help!

Hello XDAers,
I am a real noob at rooting or android-related, and a true one voided of any knowledge regarding anything IT- related.
So dear veterans, please go easy on me.
Due to my prior success of rooting and flashing my Nexus 4 successfully a few months back with no issues, I decided to give it a try to flash a custom ROM for my dad's LG Optimus L7 - which seemed an easy task compared to configuring my Nexus 4 - since there was no need for inputting any command lines or any dealing with the abd (using the easy shortcut, that is).
So, I followed the guide here: http://forum.xda-developers.com/showthread.php?t=1906133 ...
I first factory resettled the phone because it was bloated, then applied the "RunMe.bat" from the "What you desire!" folder. (Everything was already backed-up beforehand.) But the process didn't success until I've retried again and again by re-plugging the USB in because the application/PC couldn't detect the phone. In the same time, I was running KDZ_FW_UPD.exe in the background, so unexpectedly for me the phone shut itself and pushed itself to a vividly green emergency screen, then in a few seconds switched back to a screen of purple-white-blue glitches. I had to close KDZ_FW_UPD.exe without knowing what quite happened since it seemed to be the cause and restarted the process with RunMe.bat.
I didn't manage to "Restore" it first due to the fact that the phone stopped responding due to a lag asking for an encryption key. It was lagging so hard and I had to close the cmd around 5 tries while it was processing, but succeeded later on.
And then, to verify whether I've actually suceeded in rooting L7, I installed Root Checker from the Play Store. And again, for the first few tries the program froze on screen for a long period of time due to "system performance", but after rebooting and restarting the app a few times again, the ROOTING proves to be a success. Just to be sure, around this time I've reloaded KDZ_FW_UPD.exe and it suceeded.
So I went to install CWM and ES. CWM for recovery boot and ES for removing pre-installed system apps as the phone was lagging so badly. I've downloaded the CWM restoring(something like ~6.0.28?) first and tried fastbooting immediately right after, but instead of getting the fastboot menu I got a screen emptied in black with these words:
[5020] "Secure booting error"
[5020] "Cause: boot certification verify"
No hard keys could do anything on the presumed "fastboot", and so I had to hard boot again. I thought that it might be due to the lack of memory(checked on ES later on that it was 310~MB/2GB), and so I've used ES to uninstall a lot of system apps which I deemed uneccessary. So I've Googled a bit and it became apparent to me that that I've didn't unlock the device properly, so lurked around and found a file called L7CWM that is supposedly to resolve my problem, but I presume that it's the CWM recovery image that I've installed. So in the end, I didn't bother with it but kept it on tab just in case.
I repeated the same process with CWM again, but this time, the screen was joined with all kinds of flowery glitches. Restarted the device, and it went only downhill: now the Home launcher stayed all pitch black and nothing appeared. I waited a few minutes, but nothing there until the notification bar appeared. The home screen is apparently dead, and so are the menu keys. Switched to Nova Launcher(installed it just in case Home Launcher fails), and still dead. I couldn't access using any of the menu keys and had unusable launchers.
Hopefully I could still access to the settings from my status bar, but when I did, it started crashing immediately.
I've repeated the attempt a few times after restarting the device a few times, but nothing helped. It only got worse that the when the launcher did SEEM to work. It only showed the wallpaper without showing any of the icons/apps. And crashes again.
I could still access to the App menu via the settings, but couldn't open any of them and when I tried to uninstall them, the screen frozes immediately right after I gain access to the page (white page though) and gain this message: "Unfortunately Package Uninstaller Stopped!"
Then I convinced myself that the only thing I could do at the time was to factory reset the phone and then everything would go alright since I've just had to restore the system apps.
But then the black screen of death came right along with it:
"Secure booting error"
It seems that I'm out of luck... ... But just to check if I'm still left with resorts, I've downloaded the L7CWM file online...
... ...but it still didn't help.
So now I'm being left with no other choices other than asking for help. I never really understand what KDZ_FW_UPD.exe does since I had the LG Driver already before installing it, which I presume was for updating the phone to a newer or older version. And too complex tech articles are kind of alien for me.
EDIT(1 hour later): Okay, now I figured out the reason why L7CWM didn't work was because I didn't extract it to the right folder (after double checked via notepad that I was supposed to directly put it into the C:\ drive). Now it worked(?), but then it didn't.
After launching Flash_Bootloader.bat:
This message now appeared on the L7:
"Sorry!"
"SuperSU is not responding.
Would you like to close it?"
"Wait - Report - Close"
and a few minutes later
"Sorry!"
"Unfortunately, SuperSU has stopped."
"Report - OK"
Now I think the bugs till now happened was due to the fact that I've deleted a file that was required for me to launch apps... Now I just need the right fix.
After 5 minutes of screen inactivity the phone restarted by itself, kind of creepy... ...
Flash_Recovery.bat did nothing.
Reboot2Recovery.bat made it reboot but still struck on the same menu.
Nothing seems to be effective via the phone anymore, seems like I have to rely on abd but then again I don't know how... ... My dad is also f*cking pissed off ^ ^;...
__________________________________
I think that I explained the logs pretty precisely in case I missed something... I'll be very very very very very very thankful if someone could tell me what has caused my phone to fail though.
For references, here are the phone's specifications:
Model Number: LG-P705g
Android version: 4.0.3 (Stock)
Rooted:Yes (root checker)
Baseband version: MSM7227A-1-AA
Kernel version: 3.0.8-perf
Build number: IML74K
Software version: V10e-AUG-10-2012
If I don't get the phone fixed to being usable soon I think that I will get butchered real hard... ... Preferably needs a step-by-step guide made for toddlers... ...

remove the battery for 10 seconds,put it back pres VOL+ and VOL - same time and than press the power button.when you feel a vibration press for many times the button wich is down in right,try for many times and maybe it will working :}

[Q] NFC error puzzle. USB debug not an option

Two days ago my wifes 1st generation Nexus 7 refurb started giving the "Unfortunately, NFC service has stopped" error. You click OK and the error instantly pops up again. There is a moment to click on something if you're fast and I've been able to click on settings but when settings opens it's nothing but a black screen with no options. This means that I can not enable usb debugging. I have tried quite a few different processes, ADB sideload, going through the bootloader, but they all seem to require usb debugging and the tablet is never recognized. The tablet is stock but I have no way of knowing what version of android it is currently running with the blank settings window (unless you can give me a tip on that). Have done two wipe/factory restores on it and the error comes up right at the first boot screen. I am willing to pursue any option to get this tablet in working order. Rooting, flashing, whatever but I am a novice in the world of android rooting. It was purchased off groupon (won't make that mistake again) and the 14 days are past so If I have to send it in, it's cash money out of our pockets.
Do I have any options? Thank you for your time!

Most frustrating of all is that everything else about the tablet seems to be functioning normally. I can install apps from google play. I can't really run many of them though.

If the tablet has never been rooted, and the factory reset procedure seemed to complete successfully, then your symptoms suggest that something is wrong with the /system filesystem - which, for stock devices is never modified (always mounted read-only).
So that in turn suggests *perhaps* flaky hardware - probably the flash memory chip - that has gone awry and is the root cause of the problem.
It is conceivable that you could go through the process of unlocking the bootloader and re-flash a Google-provided "factory image", and that the problem will go away. But if the root cause is really a flaky flash memory chip, it will very likely return with a vengeance, and your efforts will be for naught.
There is something missing in your narrative, however - if the appearance of the "NFC Service has stopped" dialog on-screen prevents you from interacting with your (intended) foreground apps, how were you able to perform a factory reset and then follow that up with a tablet configuration? (e.g. to get Google credentials on the tablet so you could push apps to it by using a PC Web browser from the Google Play market).
If you are unfamiliar with rooting but still want to proceed with reloading the factory images, you will have to follow the Stock Recovery tutorial threads. Many users - especially those with Windows machines - seem to get stuck at this step, although truth be told that has nothing to do with Android, and everything to do with Windows Driver Installation Hell.
Note - specific to your situation.. You do not need to enable USB debugging to re-flash factory stock images. You only need to communicate with the device (booted into bootloader mode) with the "fastboot" program. For this you only need working USB hardware - not "adb".
good luck
BTW, note that you can perform a factory reset in the stock recovery without launching it from the O/S. The sequence is:
1) Turn the tablet off (not screen off, but powered completely off)
2) Boot into bootloader mode by holding Power+Vol-Down together (hold them down until android lying on its' back shows up - about 4 seconds)
3) Using the vol-up/vol-down button, select "Recovery Mode" on screen and press the power button
At this point the screen will go black. Wait about 10-13 seconds. The screen will remain black even though the stock recovery is now running. To get the screen to show the (stock) recovery menu,
4) press and release the Power & Vol-Up keys simultaneously.
The stock recovery menu should show now up. If it doesn't, try again. (After 60 seconds if you have done nothing, the tablet will reboot to the "normal" OS).
5) Use the on-screen menu to perform a factory reset (follow the directions on-screen for key usage).

Thank you so much for your response! The unanswered question is that I managed to put in the network info and what not during setup by hitting OK on the error and tapping the letter in the moment before the error popped up again. Not a fun task!
I've been trying to flash and after installing the google usb drivers it's still doing the <waiting for device> for infinity. I think I will have to bite the bullet and send it in. You saying that it might be a flash chip is kind of comforting because I think I might have bashed my skull against this issue forever before giving up!

flashed the wifi fix for the TMObile us version (from the X Note rom page)and was able to get out of the loop.

Help: G4 Plus won't start after accidentally hitting "Open" on icon pack install.

Help: G4 Plus won't start after accidentally hitting "Open" on icon pack install.
I got this phone literally yesterday, it's unrooted, worked perfectly fine until my hand slipped when installing an icon pack from the play store and I hit "Open" - the phone immediately crashed, and now will not boot. I've tried using standard power on, powering on through the recovery bootloader, and entering recovery mode through said bootloader, in every instance it displays the Motorola startup screen, plays through its sequence of animations, then as soon as the Lenovo brand icon shows on screen emits one long pulse of vibrate and then turns off again.
I can't pull the battery because I don't have the required micro-hex screwdriver. Can anyone help?

can you reboot to bootloader and start recovery? Then clear cache and see if it helps to boot your device? Or if not make a factory reset if it won't help. Maybe the icon pack screwed up something.
Report back. After that, if nothing worked, you can try this:
Is your device recognized by fastboot? If yes, try "fastboot devices" and see if it shows serial number.
Then try to flash the latest stock in the following guide rom if you have one of this devices https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138

Hi, thanks for responding. After four or five attempts to boot into recovery it succeeded; wiping the cache did nothing so I did a factory reset, which worked and now the phone will boot to the setup stage. Unfortunately now I'm getting "The device was reset. To continue, sign in with a Google Account that was previously synced on this device.", which after googling seems to be a security feature - the problem is it doesn't accept the google account credentials, every time I enter them it just cycles back to the "This device was reset..." screen again.
I know I'm not getting the details wrong since I made the account specifically for the phone and have the details written down. Any suggestions on how to proceed?
EDIT: Actually nevermind, I managed to follow along with a tutorial on how to bypass it using MotoService & ADB. Thanks again for replying.

Stuck in "Deleting all Data..." Loop

I think I've brought this upon myself - probably had a "delete all data after X incorrect password tried" set up, then my phone was in my sweaty pocket and the buttons pressed randomly...
Here's what happens when I turn the phone on
1) Normal boot into Android
2) Immediately a popup is visible "Deleting all data..."
3) Lockscreen is visible behind the popup but not accessible
4) Unable to take any step except reboot phone because I can't provide my PIN
5) Things start up as normal in the background, apps load, notifications come in, etc
6) Phone abruptly reboots into a blue screen that reads "Erasing..."
7) Phone reboots into recovery
8) I can then reboot the phone into Android again, go back to 1) above
Here's what I recall of how I've set up my phone
- Rooted via engineering boot image
- No custom bootloader
I don't think any data is actually deleted which is strange... everything that happens behind the "Deleting all data..." popup leads me to believe it's not successfully deleting (at least most) data.
Is there any way I can get out of this loop? Or possible backup all my phone data and restore it after I've reflashed the phone?
Any advice greatly appreciated, thanks

i was having the same problem when rooting my phone .Go to recovery , immediately keep pressing vol up & down ,u r in recovery. do a full wipe data settle the problem

My Galaxy Note 9 is also stuck in deleting all data due to wrong passcode entered too many times, yet my situation is slightly different.
-The phone is powered on.
-Unable to power off (must enter pin to turn off phone)
-It has a popup "Deleting all data..."
-Lockscreen is visible behind the popup but not accessible
-Unable to take any step because I can't provide my PIN
My phone is not rooted. Its normal and I am not all that tech savvy.
-Is it safe to pull the battery?

Stuck on wallpaper after Android 10 update but system won't start

So I updated my rooted 6t to Android 10 using Magisk, and everything went as expected prior to rebooting. I hit uninstall and restored images via Magisk, downloaded and installed the Android 10 update package to the inactive slot, downloaded the TWRP A/B partition module then finally installed Magisk to the inactive slot as well. Finally, from there I rebooted and it seemed to boot normally, hung a bit longer on the animation than normal but no more than 30 second or so.. it then skipped the lock screen and went straight to my wallpaper (the same one i has set, not default) BUT the system doesn't start. No icons. Can't pull up the app drawer, can't pull down the notification menu. No notification bar... Nothing.
The only thing I can do is restart the phone by holding PWR button but that just brings me right back to the same deal. I tried fastboot>TWRP recovery and was able to determine that all the system data is in fact present anyway but rebooting from TWRP also lead to the same situation.
I'm asking for advice BC the last time I messed around without knowing fully what I was doing, I hard bricked it. I'm using Blu_Spark TWRP if that makes any difference at all...
It's possible that I just need to wait longer, I read a number of reports of pixel users needing to wait hours after OTA updates but they were stock on the boot logo/animation. I'm beyond that point, only it skips the lock screen, goes straight to my wallpaper and that's it. I can't do anything at all from there.
PLEASE HELP?
Thanks!

Use MSM tool.
Download MSM tool. Unzip it on PC desktop. ConnectUSB typC cable to PC. Shutdown your OnePlus 6. Open msm download too. Click start. Press volume up and dn key simultaneously(don't touch power button). Now connect cable to phone. Progress bar of MSM download too will be active. Let it completed. Phone will boot to os. Now upgrade to Android 10. That's it.

I ended up factory resetting prior to your response, but thanks just the same. Fortunately, I didn't lose root which was my main concern anyway so no harm done. Thanks again!
