Hi,
Yesterday I decided to encrypt my brand new G4 (yes I'm late buying stuff). I'm under CM13 from 2016/03/03, my lockscreen is set to some pattern.
The encrypting stuff went well (quite fast I must say), and my phone rebooted to a black screen with a pattern entry. I entered my pattern, the phone accepted it and continued booting to another pattern screen, now with my familiar backrgound (which means it successfully uncrypted the data).
But now's the catch: whatever pattern I enter, the phone keeps saying "wrong pattern". ADB can't connect to the phone anymore (it says the pc is unauthorized).
Worse yet: pressing power+up or power+down at cold boot doesn't make the phone enter fastboot/booloader mode anymore, it just boots straight into CM13.
Even worse: entering repeatedly a false pattern at any screen (1st or 2nd) just makes the phone complain and ask again, nowhere does it try to wipe the phone.
So I'm stuck with an unusable phone, and no way to even wipe it to start afresh. Thanks CM.
Does anybody have a clever idea for getting out of that trap ?

Are you doing the recovery sequence correctly?
To do so:
Power off the phone, hold the power button and volume down, when the LG logo pops up let go of power for a second whilst keeping volume down pressed, proceed to hold both buttons down again to get to factory reset options, press yes twice and if you have a reocvery you can easily fix it from there.
OK my bad, I was releasing both buttons for 1 second. Thanks a lot.
Now going for full wipe

A friend has asked me to look at his Wildfire, he said it was updating the Market and then blank screened. Since then it will not turn on, vibrates, then nothing.
I suspected screen (replaced a few wildfire ones now) but no sign of life from touch buttons, volume key, etc - so suspect it is bricked.
Tried to flash it with RUU but the phone will not go into the boot menu via volume down & power on. I've tried numerous times and it went into boot menu once, but you could not select anything, no keys working.
Hooked up to laptop and laptop could see it, but when you try to run the RUU you get Error 170, probably becaused it's not actualy in USB Boot mode.
Has anyone seen this? Any other tricks to get it into boot menu? Anything I can run from laptop or SD card to force it into a recovery or boot menu?
This is a stock ROM phone, not modified at all.
Any help much appreciated*
I have a way but I cant remember it lol
If I can remember when I get home, i'll re-post.
OK, cool
Made slight progress today, even though I had the boot menu come up once yesterday, but no response from keys, I did notice that even though I was trying to access boot menu, it was actually acting like it was in the menu, just blank screen, i.e. if I held power button afterwards I got no vibration, but if I did pull battery and hold power, I did, as if it was booting up.
I wonder if in actual fact the screen is dead, but also there is a software hang up, as if display was dead, you would still be able to swipe the screen, get touch keys to light up when pressed, etc.
Anyway, so I went into boot mode, blank screen, pressed power anyway which would be FASTBOOT - right?
Hooked up to PC, ran an RUU and it connected OK, went through process but failed on ID, because the phone has a T-Mobile ROM and I was trying to flash with non-branded one.
So I either need to find a T-MOB UK RUU, I found one but it wouldn't run, or I need to create a goldcard (can I do that with a semi bricked device?) and go down that route.
Either way, I'm pretty sure the LCD is dead, so for the sake of £7.50 I'll replace that first, even if it has got further issues, having a working LCD will help!!
yeah get the screen fixed first.
you will only have to fix the screen later and the hassle of trying to fix a phone with broken screen, to have to have it fixed later anyway isnt really the most logical way of doing things
So, it's been a fun couple of days.
I was 'tabling' away, as usual, and my tablet suddenly reboots (if it matters, I was just opening FPSE, as I'd done dozens of times before; Skype was on background; every other process was finished). 'Ok', I thought, 'that's weird'. When the tablet's done rebooting, the lockscreen shows up, and when I try to unlock it, the scren just freezes. Couldn't turn off the screen, nothing. So, I force a shutdown by pressing the power button.
When I try to turn it on again, it just stays stuck at the Google logo screen. I tried going in through recovery, but the result is the same. Select recovery, Google logo shows up, little android with exclamation point doesn't.
I tried formating through fastboot -w, but the process just keeps endlessly deleting, while doing nothing at all. I have to quit command line, shut down tablet or unplug the USB cable with a command line message showing up (I once left it while I went for a coffee; two hours of deleting nothing at all). Same thing with trying to unlock bootloader to maybe going to recovery after flahsing a custom recovery.
I don't mind losing everything I had. All pictures are recuperable and the rest is either in the cloud or in my phone/PC. The most annoying thing would be to set up the whole thing again, wich is no trouble at all (that and going through PvZ2 and TD Bloons 5 from the start :crying: ).
I was using Android 4.4 (KRT16S), everything stock.
Is it bricked, soft-bricked, did the aliens get it? I am e-mailing with someone from the store I bought it from, hoping for a solution or (worst case scenario) RMA, but I would rather solve this without having to.
Try flashing system.img, recovery.img, and boot.img, by hand.
Your emmc likely got corrupted
How do I do that with a locked bootloader and no access to recovery? Is it possible?
Please help. This is a serious matter for me.
Started having this problem at February 14th, 02.10 AM.
Have been looking for the answers in the Oppo Forums too but still got no answers.
Okay, I have a habit, which is moving all of my applications from my internal storage to my external SD card, after I let those applications doing their functions and programs and features and so on for a while. It's not a big deal for me to set up my phone again after I restarted it, and usually it works perfectly. Just restart and I would get to operate my phone again. However, this time, I got a bad luck. The worst one, considering the fact that I'm all-around-gadget.
Here's the results I got from reading a lot of threads (not only from this forum and OPPO forums):
OPPO Swype Keyboard has stopped working? Really?
After restarting my un-rooted Find 7 (9076), I cannot type the password on my lock screen. Like any other Android devices, it would always come back to it's system or default applications, I knew that fact. But this time, when I touched the blank space to type my password, nothing came out. No OPPO Keyboard, which happened to be OPPO's default keyboard. No other keyboards. None at all.
So, I cannot do one single thing to my phone except just turn it on and stared at it like a complete idiot.
Then I decided to turn my phone off and turn it on again after a while.
But still, the same thing happened. No keyboards.
That time, I decided to turn off my phone again and pulled out the battery and my external SD card.
After putting the battery back (External SD Card was still outside), and turned it on again, the same thing still happened.
Sliding my fingers up and down, nothing happened. The touchscreen was still there, showing me my date and time even though I was sliding my fingertips up and down.
Not too long after, I felt my phone got warmer and warmer. I tried double-clicking the home button, which I already set to unlock the lock screen, was also useless. The screen was still black and locked. When it got over-heating, automatically I pulled out the battery without even turning off the phone.
That one was my fault. I knew, and well, honestly speaking, this is the first time I'm in this kind of situation. In the past, my Find 7 would just suddenly restarted itself then everything went back to normal, but not this time.
And here's the beginning of my Fastboot Loop.
Fastboot Loop on un-rooted device
After pressing the Power button and the Volume Up button at the same time, it would bring you to the Recovery Mode. When I did that to my Find 7, it brought me to a black backgrounded screen with cute OPPO mascot and some Hanzi (Chinese handwritings). Picture attached.
I tried to wait for 2-3 hours and found nothing happened.
Pulling the batter out and putting the batter back would do the same.
In other words, I am not able to gain access to my Recovery Mode.
Why didn't bring the phone to the service centre?
I thought about this already.
When I tried to connect my phone to my pc, it can detect the phone but cannot access the files because the phone was still locked with the password.
Usually, the service centre requires us to unlock the phone if there's a problem with it, right? In my cases, yes.
I was searching all night to find out the answers.
I found some threads about the Fastboot Loop thing and etc, but they are only for rooted devices.
I'm using:
OPPO Find 7 (9076)
Color OS 2.0.5i Beta
Android KitKat 4.4.2
Device is not rooted, still original.
Still dealing with the same problem until now (the time I post this thread).
Anyone has solved this problem and guide me step by step to finish this?

boot into recovery and format the phone, this should fix it. If you want to backup your data, just boot into fastboot, connect phone to pc, run fastboot command from sdk tool, push custom recovery, flash twrp, make nandroid backup, fomat phone along with all the storage and then flash oppo stock rom (you need to download) or any other custom rom with gapps. To restore use nandroid manager, do not restore system files if you are flashing custom rom.

Thank you for your help Sir.
But, my Find 7 already operated normally again since I left it for a few days uncharged and off.
Then I got into Recovery Mode by pressing Power button and Volume Down button (not Volume Up button) while in the middle of my fast-boot loop.
It worked. I could gain access to ColorOS Recovery Mode.
So, I reset my Find 7, then re-installed my applications and everything again.
Thank you for answering!
***SOLVED***
I ended up taking the SIM card out, opening the phone and detaching the battery. The phone came back to life when the battery was re-attached. Its in sorry shape for other reasons, but alive enough to get data that was not auto backed-up.
-----------------------------------------
I recently used the volume button + power combo to get to the reboot screen of a fire phone. This phone had TWRP installed. I was trying various methods of getting the phone to stop booting in "Safe Mode".
Note that I rebooted from Fire's recovery, not the TWRP recovery. No software was installed or removed before the reboot. I was only looking for ways of escaping "Safe Mode".
I chose "reboot" in the volume+power combo screen and the screen went black. Since then, I have been unable to boot -- I can't get the amazon logo or any sort of vibration. There is no charging logo when I insert a USB cord.
What can I do to reset or reboot this phone? Naturally, I've tried holding down the power button for long periods of time.
I'm fine with opening it up to get at the gnomes inside if need be.

mine happened the same thing... apparently battery is in good state, there is no overheat... mine was a 9008 brick type... so is dificult to relive...
Hello, I would like to first tell you the story my LG G4 has gone through and then I tell you the error.
So, at first my phone was working absolutely properly. I accidentally deleted some pictures and to do a recovery, I had to root it. And rooting would be useful for later so why not do it?
So I first unlocked the bootloader through the code from the LG site. After unlocking, the phone reset (because it would be just too good to make some memory changes and nothing more.) But allright. Then I was ready to root. I just booted the phone, everything was fine. I unlocked the developer mode and opened ADB. I rebooted to recovery through
Code:
adb reboot recovery
I was expecting to see some menu with buttons (but that would be just too good). However, I saw just android with a red triangle in the middle. Nothing more. No response to buttons, nothing.
So I thought. Allright, let's boot into recovery using hardware buttons (vol down + power) at startup. Unfortunatelly, it seemed like there is no such mode System just normally booted (and that was just after bootloader unlocking. Recovery mode goodbye.).
I tried to send commands to the phone using diagnostic port. Unfortunately, it responded by FAIL to every command.
I reboot to bootloader and booted an image: "boot-em.img" (from here: google: how-to-root-lg-g4-on-android-6-0-marshmallow-20a20b-firmware. I'm a newbie here. thx for understanding.)
After that the console uploaded the image and booted successfully. Then, however, system started to boot up and was endlessly booting (LG boot animation) till the battery was critical.
I was able to access the EMI number through volume-down button and volume-up button pressed simultaneously.
I was also able to access some factory-reset dialog by holding volume-down and pressing power-button several times. I choosed to reset everything and then accepted it with one more 'are you sure dialog'. System rebooted and was stucked in the LG boot animation.
Then I got to download mode, since recovery mode was lost in hell. Through LG-UP I flashed the original KDZ firmware and everything got back to normal, but recovery mode was still inaccessible through the hardware buttons. I got through the process of setting everything up, getting developer, rebooting to bootloader and I booted TWRP.
TWRP loaded and it responded to double-tap on screen to wake it up. I just checked the menus and let the phone sleep.
After several hours I went back to the phone and double-tapped on display. Nothing. Phone was not responding. I pressed the power button and the phone restarted (I think. It either restarted into the system or was not responding to power button.)
So I got to the system and again rebooted to the TWRP (through fast-boot). I tried to back-up one partition to the disk. During the process phone had turned the display off. So I double tapped. Nothing. I removed the SD card and the phone woke, saying that back-up process was not able to complete. Suddenly it stopped responding to double-tap. It woke up through an interrupt. I re-inserted the card, successfully backed-up the partition to the SD-card and I left the phone laying on the bed plugged in the charger. It stayed that way for 4 hours or so, doing nothing. All of a sudden, a yellow screen was there, (and that's a screen of absolute death that was never supposed to come. Little I knew.) saying that an unexpected critical error happened and to do a memory dump, insert a cable, set up some communication (I don't remember what it was, didn't take a picture of it.) and it could send the memory dump to PC or somewhere. I thought to myself. So, the application is not so stable after all. It said that to reboot just press the power button or something.
And now the problem comes:
The first start: Bootloader booted, LG animation went on and finished. The starting up apps dialog came rolling. Then, system restarted.
The restart: Bootloader booted, LG animation went on and freezed. Then, the phone restarted.
Second restart: The same thing as the first one.
Fourth restart up till now: Bootloader tries to boot and restarts before the LG animation.
I got to download mode and it restarted even there. After re-inserting the batterry I can sometimes get to the Firmware Update window and communicate. There I flashed the official firmware again.
No success, as if I didn't even do it. It restarts before the animation.
Can I do anything with the phone? Hopefully I can. No hardware problem occured (except for a situation where the error could fry the wires inside the mighty System On Chip.)
For the software state I cannot even tell but I might say it's cooked just wrong. That's why I came here.
I know I did some pretty stupid steps. But the error was not done by me. It worked fine and after the yellow screen which came by itself, it just (some bad words).
Thanks for replies.

Solution
So, I was looking around and believe it or not, this problem disconnected the pins on the motherboard's snapdragon 808.
I think this happened: The device, although it was heated many times during its life, it withstood that so far.
However, a longer run of the TWRP had finished it off. Memory got disconnected while running and it threw a yellow-screen.
Pins got disconnected and from then on it was just a standard common LG bootloop issue.
The continuous process of dying (First it partially loaded, then only animation, then nothing) is explained by this fact that the pins were so-so there and a couple of reboots just got it totaled.
Temporary fix:
Pre-heated the memory chip to 250°C using Hot-Air gun. After 18 seconds at this temperature I pressed the memory on top of the snapdragon down to the board while cooling.
Then I added a little metal square on the metal part that is covering the system on chip. This part is over the SOC where before there was just some tape.
This can work for several days in sleep mode or a couple of 'heat-demanding' operations on the phone.
Permanent solution should be to reball the memory chip on the snapdragon. That's my next step.
