HI All
I dropped my phone earlier today, but it did turn on, but really slowly and when it turned the screen off it stayed off unless I reset it.
So I thought to reset it. forgetting that the RHODIMG was on the SD card. and fogeting the hard reset variation, so I let the image (cookie energy) run. it completed perfectly fine. but then after a reboot it just sat on the vodaphone splash screen.
So I ran the image again and this time it got upto the starting windows for first time, but for some reason it turned off. and since then it just turns itself on runs boot loader and turns off.
It only does this when plugged in. I can't stop it turning on if the power is plugged in. and I can't turn it on if the power is not plugged in.
Included are a photo of the Bootloader screen from a previous update last year(working) and then a short avi and jpg of the current bootloader.
Cheers
It looks like the bootloader isn't seeing the ROM anymore, try flashing another rom. If your SD Card isn't empty try formatting it (Backup your files) and try flashing it with only the RHODIMG on it. Good Luck

So after an unsuccessful ROM flash my phone was stuck at bootloader for quite sometime...i had a micro SD card reader and inserted it into multiple computers running XP, vista and ubuntu...they all registered that i had plugged something in but wouldn't show it as a disk drive...now i've already figured out how to access it but i put a new ROM image on it and tried to reflash but after the flash when my phone booted up it simply switched itself off... when i switched it back on it went back to the bootloader and tried to reflash the ROM. mid flash it just switches itself off... I realize that this is probably due to the charge level of the phone so i plugged it it but it will be off and charging then it will suddenly decide its got enough battery power and boot up to the bootloader screen until it dies again...how do i stop this vicious loop

Something worth trying:
1.You could take out the battery for one minute or longer.
2.Now put the ROM's .nbh on your SD card [Make sure it is named "RHODIMG.nbh" (no quotes)].
3.Put the SD card and battery in and press/hold Power button and the Volume Down button at the same time.
4.That'll put you in Bootloader Mode, and it should ask you if you want to update your phone's image (something like that).
5.Follow the prompts and it should start flashing (you'll see the bar).
6.Soft reset after the flash says it's complete.
I once went through that and this is what I did. I was able to unbrick my phone.
However, (back in September/October) there was another instance of the same thing happening to someone, but he never got it fixed; he did get the stock ROM and SPL back on it, but had to return it to HTC because it still kept cycling into Bootloader.
Good luck!
I was trying to flash the new version of EnergyROM and when i ran a task29 i accidently left my SIM card and SD card in. I loaded it to the bootloader screen and it was saying USB on the phone but my computer wasnt recognizing it so i went and bought a card reader and tried flashing from the SD card and now its stuck on a black screen with the red light in the corner always on. the phone wont turn on and the light only comes on when its plugged in. please please help me i just bought this phone 2-3 weeks ago and didnt get insurance.
Generally, if it is bricked, it won't turn on or just constantly reboot. You can access bootloader mode by hitting the down volume key while holding the soft reset button.

that what it seems to be doing, ive run task 29 twice and tried to reinstall the ROM that worked earlier today and it just loads up to the BRGD ATT world phone screen and acts like it wants to boot up and then just goes back to the black screen any ideas on why?
Phone turns off during use and will not complete boot unless plugged to charger even when the battery is almost full.
This error started last night after I did factory reset because of observed phone lag. I did mistakenly "wiped internal storage" but got the alert of "no OS during reboot", so I restored from my backup from SD.
the phone started properly but went off during initial setup and will go back off each time I tried turning it back on. I thought it was battery so I plugged it to power.
it did boot but will go back off once I have few touches on the screen.
I had to leave it plugged to setup my accounts else it will go off.
I'm using its Wi-Fi to send this message via my PC because any 2 - 3 touches will switch the phone off.
once it does that, it won’t even boot to bootloader before it goes off again unless plugged to power.
what I do to solve this please??
Problem has been solved.
It was actually the battery. I got a replacement and the device is okay now.
Thanks.
EDIT: It was a hardware issue; apparently the start button was stuck, causing it to enter on a power off/on loop. It's been corrected since. Thanks for your interest.
Just a few days ago I installed LineageOS 14.1 on my device. There were some problems, mainly that audio was bugged up and phone calls would lose all voice and audio after some time. As a result, I decided to install OctOS to see if those issues weren't present.
As I was booting into recovery mode, I plugged my phone's charger since the battery capacity was at 40% and I feared it would shut down in the middle of the flashing process. So while it booted into TWRP, it shut down several times. At the last occasion, it booted into recovery successfully, then froze for a few seconds and then shut down.
From that point, the device turns on, shows the Samsung logo for a split second, then turns off. The same thing happens when I plug it in, and I can't even boot into Download mode without the same thing happening.
Did I break my phone, or do I just need to charge the battery?
Thanks in advance.
Try using debrick img and write it to sd card with Win32Diskimager then put it in your phone and boot into recovery and redo the rom install.
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.
