[F240] Stuck in Boot Loop but Unable to Enter Anything - LG Optimus G Pro

I have F240 stuck in boot loop. I flashed a custom rom (I don't remember its name but I heard it mimics G5 on G Pro) and I forgot to wipe. That caused a boot loop.
I tried pressing all buttons along with power button, but that just gave me a black screen, which would reboot when I let go of buttons. So I tried Pressing VolUp+VolDown and connected USB cable, and it just charged. Yeah, it went to charge screen.
To confirm those black screen wasn't recovery or anything, I tried
Code:
adb wait-for-device && adb reboot
on Command Prompt, tried several things, resulted nothing.
Thanks in advance.
P.S. Tell me anything! I'll do that!

@minary Usually, you can enter download mode even if the screen is black.
You will only be sure when the flashing tool start extracting the kdz. Thus, indicating that the phone is recognized.
So you can go back to stock and start all over.

Thanks a lot! But sadly, I have solved this problem. It wasn't anything related to software. Actually, it was a hardware problem, a very common one that is. The Vol- button wasn't working! USB also had a hard time connecting it.
Thanks for the answer though. I really appreciate it.

[Q][Solved] Stuck on boot animation! How to get in bootloader?

I had just flashed the BlackICE ROM and started to like that, except from that it sometimes froze. So I read the BlackICE forum and saw that there were a few others with the same problem, and they got tipsed about undervolting with the built-in undervolting menu. So I did so too, and it worked about 1 hour. Then it froze again and won't come pass the bootanimation.
Normally i would press power and vol down button, but my vol down button has it own life, and won't function when I want to. So i can't get into the bootloader and reflash or wipe data.
Any helpful tip? Any other key kombination, or maybe i can access it from my computer when plugged inn with USB?
Thanks!
Sorry to hear about your problem.
Try this,
Download this simple adb package --> HERE & extract
Remove & reinsert your battery
Plug into your PC and wait for the orange charging LED to light up
Using cmd navigate to the folder you unzipped adb to
e.g
Code:
cd C:\adb
Now try this command
Code:
adb reboot bootloader
Hopefully that should restart your device into bootloader, from there you can select recovery.
Thank you very much for your answer, but I don't see any link? It seemed like you wanted to post a link?
EDIT: Is it this package maybe? 34MB?
Link: http://dottech.org/tipsntricks/2153...ows-computer-for-use-with-your-android-phone/
Ahh yes, I forgot the adb package.
I've added it to the original post. It's only 200~KB.
It worked! But are there any adb command to enter recovery from bootloader? Since my volume buttons don't wanna cooperate I am not able to get down to "Recovery" atm. I tried volume up, and it worked for one selection, so now it stands on the bottom.
Thanks again btw
I thought it would, you can try,
Code:
adb reboot recovery
You may need to pull your battery & start again.
I tried that and then I just got a long list of commands that I could try out. I then found
Code:
adb reboot [bootloader:recovery]
That did not work either, so I just tried rebooting into bootloader again, and now the volume up button would work long enough to select recovery! So now I have reflashed and things seem to be working again
So thank you again, for saving my phone
possibly bricked??
I have tried the steps above and am getting "Error: Device not found" I am assuming this means that the usb debugging has somehow been switched off?
Complete newbie please excuse me (I have got my phone stuck at the htc screen and volume down button seems to have died on me)!

[Q] Tried to install Beatmod ICS, stuck on "screensaver" usb and recovery won't work

[Q] Tried to install Beatmod ICS, stuck on "screensaver" usb and recovery won't work
Hi guys,
I've watched the n00b video and been googling for the last few hours as well as reading through various pages on the XDA forum. I've found a lot of problems that are kinda similar and tried various solutions but don't seem to be quite getting there.
Basically I had Virtuous Affinity as the OS and clockworkmod installed (should be the most up to date versions of both, they were put on no more than a week ago) as well. I also had a backup of current OS and so on on the SD card, as well as the original zip of the rom.
I decide I want to give ICS a go and so I downloaded the betamod ICS and then loaded it. It asked me if I wanted to do a dalvik cache wipe, a dalvik cache + data wipe and a third option I don't recall. I went with the dalvik cache wipe (at the time I was under the impression that was the correct course of action) then put it back in my pocket while ICS installed.
I get my phone out of my pocket later and it's kinda stuck on what looks like (but logically isn't, I'm guessing it was meant to be a splash screen type thing while ICS installed or some such) a screensaver which just loops endlessly. The only thing you can really do is take the battery out and turn her on again, in which case you once again end up in the endless screensaver loop.
I've tried booting to recovery using volume - and the power button and unfortunately it just boots straight into the looping screensaver again.
Getting a bit worried and feeling adventurous I tried seeing what I could do with ADB, however the computer seemed unable to recognise that any device was connected with ADB devices not listing anything.
I've read up a lot and I'm at a loss as to what to do - there's a rom on the SD card and there also should have been a backup but I just can't get it into recovery.
I do have the ability to view the SD card on another device and interact with it, so if there's a potential SD fix, that's certainly not out the window.
But yeah, I'm clueless how to proceed here and very green at the whole rom business. Can anyone advise what I might try to do from here? I don't care what state I end up going back to, or if I lose my data, I can get all that back, I just want the phone in some semblance of basic operation.
I'll be keeping an eye on the thread, if I've left out any pertinent data ask away and thanks in advance for anyone with a clue how I can fix this mess .
EDIT: Post may be better off in ICS thread above and I do apologise if so, I would move it but I seem unable to delete it.

I have, it doesn't work. I've left the battery out for a fairly long period. Volume - + power still just brings it back to the "screensaver" loop.
Thanks for the suggestion though.
Turn the phone off completely; pull the battery out for a bit then replace it and don't touch anything. Don't try to turn it on. Plug the phone by usb to your pc (still turned off). At the command prompt in the folder containing adb.exe type "adb reboot recovery" - the phone should power on and go to recovery where you can wipe properly and reflash whatever you want.
You should be able to boot to recovery using the volume down + power button combo (hold the volume-down key, then press and hold the power button and keep both held until you get to the bootloader menu); the only thing that's wrong with your phone is that you've flashed one ROM over another without wiping it first, so the ROM can't load but this shouldn't affect your bootloader or recovery.
Worst case you can flash a RUU which will restore it to the official firmware; you'll then need to re-root and re-install a recovery image to be able to flash custom ROMs again.
Very helpful post, thanks! I'll try all that and see how I go, I'll post if I still have trouble.
Yeah I dunno why I can't boot to recovery it's weird. The volume button wasn't working, so I removed it and am pressing in the volume down portion of the volume button with a pen while holding down the power button. It's possible perhaps I'm not successfully depressing volume down, but I'm 99% sure I am and that that's not it. I am however doing it as you and other guides advise, depress volume down, hold it and then depress power and hold both for about three seconds, no joy!
Anyway, as said, I'll try what you're recommending and see how I go. Thanks!

Curious what you mean by this? Cause there's no command prompt in the folder ADB is in. Do you mean in command prompt, be in the folder, i.e. c:\abd kinda thing? I tried just loading command prompt and typing abd reboot recovery, no device detected - no joy.

Yeah that was what I meant; I've got a feeling that that only works when the phone is powered off if you had USB debugging activated on the phone beforehand, so if that's not working that might be why.
c:\adb
results in error: device not found.
ADB app itself is in C:\adb\platform-tools but when I try that it goes The System cannot find the path specified. I've tried cd/adb and I can get that far but I can't get to adb/platform-tools.
EDIT:
Okay, I managed to get to c:\adb\platform-tools but adb reboot recovery is still advising error: device not found. Guessing perhaps I didn't have usb debugging enabled. Are you able to suggest another work around at all? I'm happy to flash it to whatever, I don't mind losing data, just want to get it in working order again. I don't see how I can though when I seemingly don't have access to recovery or USB...hrmm, must be some way around.
Accidental double post, sorry.
You need to try get into recovery mode, where you can do a full wipe and see if that fixes anything.
Firstly, remove your battery then re-install it, your phone should still be turned off at this stage. Press and hold the volume down button, then additionally press and hold the power butter, until something appears on the screen. If the bootloader appears, you can then boot into recovery from there.
If the above fails to work, report back with your results and hopefully something else will be suggested.

Your only other option to get into recovery is the volume-down/power-on combination. Like I said, I can't think why that's not working unless it's related to your missing volume button (maybe it's not maintaining a constant pressure on the button when you're using whatever to press through the hole).
If you still can't get that to work, I would suggest finding a stock RUU and flashing that. It's an .exe file that runs from your PC and will return your ROM, bootloader and radio back to stock. Obviously that means you'll lose root and your custom recovery so you'll need to do all that again from scratch. There's a sticky in the dev section with a link to a thread with various RUUs (it's named something along the lines of "shipped & test ROMs" - I'll check that and link to it once I've dragged myself out of bed to the computer). You'll lose all your data, but if you took a backup beforehand you can restore that once you're back up and running.
//sent from my Desire HD using Tapatalk; all errors entirely intentional.
Yeah I'm starting to think perhaps the down button is just broken.
What state should the phone be for the RUU, turned off with usb plugged in or turned on? Bearing in mind, that when on, all it will do is the "screensaver". Will it work in either of those states?
Thanks, will deffo research more when I get home. Appreciate the help immensely.

Guessing you mean that as far as the ruu thread. Am downloading a stock rom atm, with shaped internet till tomorrow, meh! Will see how I go. Have a feeling phone was probably Vodafone branded at stock though, so that could make for extra fiddling but yeah, fingers crossed.
If you are able too install a stock-rom you can work from their than install 4EXT recovery
touch than you doen't need the volume buttons.
I downloaded the most recent stock rom on the link above. When I try to install it though, phone off or on, it advises a USB connection error. Is this likely to be because I originally had vodafone stock and need to make a gold card, or should it still at least be recognising it? It does advise not to run any programs on the phone or anything when while installing the update, but of course, as long as my phones turned on it's stuck on the damned screensaver loop.
http://forum.xda-developers.com/archive/index.php/t-841890.html
Gonna give that a go, fingers crossed!
D'oh, just found out my mobile was Three at stock and not Vodafone, the search continues .
Gah, I'm about tearing my hair out here, I want my damned phone back . Stuck using a $79 Huwawei Vodafone thing at the moment and it's so so so awful.
Anyway. I was under the impression that making a goldcard would mean I could RUU a non-Three stock rom on the phone. I made a goldcard following these instructions; http://www.addictivetips.com/mobile/how-to-make-gold-card-for-htc-desire-hd/
Then I turned the phone on as the RUU advises, (meaning it's scrolling through the feckin' "screensaver") and start the process and once again get a USB connection error.
What's the better process at this stage, try and take it back to Three stock? I don't see how I can at the moment, the only Three stock I can find seems to be rom, not RUU, meaning I'd need to load from the phone, which I can't due to no recovery. Or should I keep trying to get the goldcard thing to work, maybe try some different RUU's or something?
I'm open to any other suggestions as well. Had a bit more of a fiddle around with my volume down button, no matter what I do though, I can't get recovery mode. Always boots first to the white HTC screen and then starts the infernal "screensaver" loop.

How come the volume down button be broken. When you were using Affinity Rom weren't you able to use your volume button for music. Remove SD card from phone then press "First - Volume down gently for 2 sec" & press-hold power button when it goes into bootload place your sd card back select option "REBOOT RECOVERY". I think your panicking too much just be patient nothing is wrong, i think your just hurrying it up...
The volume button didn't work before either. I had to manually adjust volume from settings. I thought it was just because of the dodgy plastic button on top, but using a pen to depress the button underneath doesn't work either.
Believe me, I've been trying to fix this for days now, every different way of depressing volume down in order to get to recovery has not worked. Short of taking the phone apart and seeing if I can see what's wrong with the button (doubtful with my level of expertise) then it ain't happening via that method.
Got a little bit hopeful with this;
http://www.htcdev.com/bootloader/ruu-downloads
But that too requires my phone to be in usb debugging mode, which of course, it isn't.
Is there anyway to force the phone into usb debugging mode using some form of hack or some such? The thing is, it is powered and everything, I can turn it on, the screen works and all that jazz and indeed the phone will charge from USB and the computer makes a noise when I plug or unplug it, the phone itself however won't do anything other than the "screensaver" ICS installation loop. I guess I'm thinking where there's life there's hope and perhaps there's some way in that state I can get it to switch debugging on, though I think I'm reaching at this point .

[Q] Need Help - Bricked Kindle Fire

I got this kindle fire that I am trying to fix for my kid. I don't know what firmware was in. The KF has never been rooted. We tried to call Amazon for a replacement, but since I didn't remember which email account was tied to this KF and I couldn't find the Serial Number either, I got stuck with it. If could make this device to boot one more time to see the amazon account or the serial number that will be great.
Well anyways, these are the symptoms. After lots of hours of reading about bricked Kindle Fires I decided to order a factory cable suspecting the problem was a low battery KF going into a 5 second loop. The process went good. I was able to flash FFF 1.4a and TWRP 2.2.2.1 by going into fastboot mode, but the problem is that the KF does not want to start in recovery mode, nor in normal mode.
At this point, I think I can rule out a battery low problem, but I am not sure.
No matter what I do, I cannot enter to adb mode, and this is the real problem I don't seem to find an answer. If there was a way that I could upload the firmware from fastboot mode or a tool that forces recovery mode.
As I said this KF was always stock until today that I tried to unbrick it by installing the FFF and the TWRP. The TWRP never started.
As I said earlier my only objective at this point is to recover the serial number or the account email associated with my KF.
Question 2, how can I revert to the stock bootloader if everything else fails?
Any suggestions, links, ideas will be welcome.

I hate to ask this question but do you know how to access recovery by using the power button to get the boot menu then selecting recovery? If you are using the boot menu to attempt to access recovery and its not cooperating it`s possible that points to a broken bootloader or a broken recovery. When you flashed both fff and twrp did you see that it sent and physically wrote each one? maybe explain how you flashed them so we can see if a error was made there. What level do you believe the battery is at? Possible it could be playing a role in your present issue.

I have done a lot of experiments with my SGS2 about installing ROMS using ODIN or CWR, backing up my own images and making backups. Most of the work I do though is in CWR. I haven't dealt with TWR yet. I also installed ICS on my HP Touchpad. So, even though this is the first time I deal with the KF, I already some experience working with ROMS and images.
Back to the process. I installed the FFF using the Kindle Fire Utility. The KF was forced to fastboot mode via the factory cable. At first I could see on the KF splash screen with the black and orange logo, and now the KF is booting using a Black and Blue kindle fire logo with 1.4a on top. At the bottom of the splash I see instructions of the bootloader selector indicating to press the power button and select the mode that I want to boot. Either Normal Mode or Recovery Mode.
I flashed the TWRP 2.2.2.1 in fastboot mode using my command prompt by putting this code:
Code:
fastboot -i 0x1949 flash recovery [path]\openrecovery-twrp-2.2.2.1-blaze.img
I was following the instructions on this guide.
http://forum.xda-developers.com/showthread.php?t=1638452
I got stuck on step 3 after attempting to boot into recovery mode.
I can select which boot mode I want to go, but none of them work. I only get on the bottom of the screen saying Booting... and then the KF shuts down.
I suspect the battery had a good level of charge, but I can't tell for sure.
Thanks for everything.
Download TWRP again, check the md5, reinstall, and post whatever error messages (if any) that are in your command window here.
In the meantime, enter the following command and let me know what happens after you reboot.

All commands were successful.
When I'm doing instead of the fastboot reboot is to remove the factory cable. Shutdown the KF by holding the power button. Then I connect a regular USB cable. The KF starts the boot process. It enters the first splash screen. Then it moves to booting, but the booting fails. The only thing that I see is that the button light turns from green to yellow and then it shuts down. And the boot process starts again going into a boot loop.

Thanks for reading my thread.
If upon rebooting, the result is the same after changing the bootmode, it is possible the bootloader isn't working properly. If that's the case, flashing a new bootloader (with md5 verified) might not work, but it's worth a shot.
If that doesn't work, you should be able to change the bootmode to USBboot (4003) and use Firekit to replace the bootloader, but that's speaking theoretically. I've never tried it so I couldn't tell you whether it would work or not. But then you could always pull the back cover off the device and use the shorting trick to use Firekit in USBboot.
If installing a bootloader with the Firekit doesn't work, you're likely looking at a hardware issue, and there's not much we can do about that.

If you have any questions about using Firekit, don't be afraid to ask.
Get your device working properly before attempting to revert the bootloader back to stock. Contrary to what you may think, the custom bootloader is much better for you in this situation.

I suspect your battery is still depleted because it still sounds like a 5 second boot loop. Try this hold the power button down till it`s off and plug it to your pc for a few hours to see if you cannot get some power to your battery.

I think that would be the case if the device just rebooted. The OP is saying the device shuts down when FFF starts to load the operating system (Booting...) or recovery, which is why I think it is either the bootloader or some hardware issue.

I have nothing to lose. This KF is already bricked. I can certainly try anything. Which cable do you suggest I use? the Factory cable or the USB cable?
I think I answered my own question now. Using a regular USB cable puts the KF in the bootloop. I will use the factory cable instead. I shut down the KF, put the factory cable connected to my computer and the KF. Right now the KF is in the KindleFire splash screen waiting for fastboot commands of for me to use the button to tell it which mode to boot. I will leave it plug overnight.
Thanks for replying on my thread and trying to help me.

That looks like your battery. From what I can tell, the device is just rebooting, not shutting down.
Unplug the device and hold the power button to perform a hard shutdown.
Plug the device in (it should power up on it's own) and hold the power button to shut it down again.
Leave it plugged into the computer until sometime tomorrow and try again.
Same thing I was thinking 5 second bootloop Thank you the video was very helpful to see just how its acting. Use stock cable to charge not factory.
OKay. I'm glad I came to check the thread one more time before going to bed. I removed the factory cable and put the regular usb instead. The KF was rebooting. I shut down the KF by holding the power button without unplugging the cable. Now the KF appears to be shut down, but the cable is still plugged. The yellow light does not appear as it normally would if it was charging though. I don't know if this is normal.

I think you're fine let it rest.

[Q] I can't access Bootloader or Recovery PLEASE Help!

My HTC One M8 (Verizon) is seemingly bricked. My phone is rooted, S-Off, with the stock ROM. I have been trying to update to the latest OTA update by returning to stock. I had previously modified some entries in the Build.prop and Platform.xml. I knew those had to be default in order for the OTA to work. I had copied the original files and pasted them to my SD Card so that I could simply cut the modified versions, paste them to my SD Card, and cut the originals from my SD Card and put them in their corresponding system folders.
Upon a reboot something apparently went horribly wrong because all my phone does now is boot with the white screen and green HTC Logo, then the screen goes black. I have tried the typical Power Button + Volume Down but it won't enter the boot loader. The good news is that the USB port seems to still work for my windows computer recognizes a device connecting to it but it doesn't show up as an interactive device in windows explorer..if that makes sense.
Please Help!

When you connect it to the PC can you pick up the device with adb? If so, have you tried to run the command from adb to boot it into bootloader? adb devices ... if found, adb reboot bootloader
:fingers-crossed:

I'm not too familiar with ADB commands but I typed in "adb reboot recovery" and it said: "error: device not found" so even if my command was wrong it's still not detecting it. I also tried: "fastboot reboot bootloader" and it just says "waiting for device"
Also I feel like it's worth mentioning the phone is automatically rebooting every two minutes or so (haven't timed it exactly but it's a while). Still showing the green HTC Logo then the screen goes dim, then the screen turns off.

Try holding volume UP + Power button, this simulates a "battery pull", just hold it in for a while it can take a while to "pull", when it's off try again booting into bootloader, volume DOWN + Power button.

I held Volume Up + Power Button and it showed the white screen with the green HTC logo. I then released all buttons. Once the screen turned off I then held Volume Down + Power Button for two minutes straight and nothing happened.
Even though we haven't found a solution yet, I am appreciative of the help.
sounds like you never installed the htc drivers for your phone, hence your pc doesn't see the phone when you are doing ADB commands.
install the drivers for it, then try the ADB commands via your pc
and dont mess with the build prop or other system files unless you have a working back up and are 101% certain about what you are doing..
Just remember to change directory in command prompt to the folder where adb.exe is located.
I don't know why the device doesn't reboot into bootloader though when you hold volume down + power button, shouldn't have to hold it for 2minutes. Holding volume up + power button to simulate a "pull" should only take up to 20 seconds or so at most and pressing volume down + power will then immediately take you into bootloader mode, or at least it's supposed to.
Did you release the volume up / power combo when the screen went dead or before? Try holding it until the phone shuts off and then right away press volume down + power.
Sorry if I'm not answering right away though, busy eating, and will be here and away for the next hour or so while I get ready for work =o( once I leave for work I'll only be able to help some more after like 2 hours or so. Hopefully we can do something before then though =o)

You're right, I didn't install the drivers. I did so and ADB was able to recognize it and I was able to access the bootloader. Thank you everyone for your help. I won't be making the mistake again.

So you'll be able to fix it from here on then? I was just about to link this thread to you as well should you have gotten adb to work again, it's for the RUU for Verizon seeing as you said you're on Verizon.
But going by your response up there you might already know how to fix this issue further :good:

Indeed I appreciate it, but I just finished installing the RUU ha. Hopefully this thread will be of use to someone in a similar circumstance in the future.
Share another method of getting into recovery mode on non-responsive blank screen
Hi,
I just want to share how I accessed recovery mode with the same build.prop issue but with S-ON (might work with S-Off too).
I found the solution from here:
http://forum.xda-developers.com/htc...ter-download-mode-t2853100/page2#post62490577
To get into recovery mode on a non-responsive blank screen, hold the power button and volume up button at the same time and then approximately after 10 seconds, switch from pressing the volume up to volume down button before the HTC logo white screen shows while still holding down the power button. After, a white boot screen will give an option to go into recovery mode.

No access to bootloader or recovery after a custom ROM install attempt

Hi everyone,
So yeah, I probably shouldn't have played around with recovery, bootloaders and custom OS, but my XZ2 Compact was rendered nearly useless by the last Android update, so I tried to install the new official Lineage OS on it. But I failed. Hard.
Symptoms
The phone now only reacts to the power button. When I press it, it displays a battery charge icon for a minute or two, then the screen turns off.
None of the other physical buttons do anything, and the button combinations don't work. As a result, I can't boot to recovery, or even access to fastboot.
The light indicator is on and red.
I let the phone drain its battery, see what happens, and well, nothing. Eventually the screen stops turning on. When I replug the phone, even if I don't touch anything, it will end up showing me the battery icon again, and is stuck in the same loop.
'adb devices' still sees my phone, but with no permissions. 'fastboot devices' doesn't see anything.
On Windows, Emma (Sony's flashing tool) doesn't see the device.
Causes
I was following this tutorial. I went up to "temporarily booting a custom recovery using fastboot". I used the latest LineageOS recovery for my phone, and the flashing worked fine according to the output of the fastboot command. But that's all. Impossible to do anything after that.
Do I now own a glorified paper weight? Or can I save this?
Thanks!
SOLVED! I managed to stop the charging loop with a key combination I discovered: volume up + volume down + power for about 10s. Then was able to load the bootloader and re-flash a recovery, custom ROM etc. Thank you all for your help.
Have you tried to hold vol+, vol- and power button all together for (at minimum) a minute?
I would then try to restore stock firmware with newflasher (you'll find it using Google search or here on xda).
Great, thanks a lot I didn't know this key combination and it allowed me to get out of that charging loop and start the bootloader. Problem solved!
Nice, glad to hear!
