[Q] LG G2 stuck in Firmware Update Screen (+loop)

Hello Guys!
My Problem (I've looked for about 2 hours in the forum, but can't find anything similar to my situation):
Got my new LG G2 (D802, 32GB, Android 4.4.2) today. I wanted CyanogenMod on it, so i unlocked it, etc...
But as i have installed in recovery mode, and after that i always got stuck at the CM 10.2-Boot screen i decided to install the stock android back onto it.
i went into download mode, choose the right .kdz-file and tried to flash it with LG Flash tool 2014.
But it got stuck there at 20%. My current situation: I can't get out of the screen where it says "Firmware upgrade and 0%, und below is "B75" and "rooted". When i press the power button for some seconds the screen gets black, then the LG logo appears and immediately the Firmware-upgrade-screen appears, again with "0%" and "B75" and "rooted".
I also can't get into recovery mode: When it push volume down and power butten, and it asks me to do a factory hard reset and i press the power button to confirm (when normally then the recovery mode menu appears) it changes automatically again to the Firmware-upgrade-screen.
Thanks in advance, hope you can help!

Were you doing all this with the phone still plugged in? If so disconnect and long press power for 15 seconds. Then again try to enter recovery. If you still can't get in, power off and retry download mode again with a fresh connection.

it's not working.. i've powered the phone off, then i get with volume down and power button to the screen where i have to confirm twice with the power button and them next comes the firmware upgrade page...
i have also no chance to get into the download mode with volume up and connect cable..
any other ideas?

Well what you're describing there IS download mode. At the top it says firmware update. The progress bar reads zero until it detects an update being performed. Like this...
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
That's download mode. Maybe check in device manger (if windows) while the device is plugged in and on that screen. Does it show up as LGEAndroidnet USB serial port? If yes, that's the proper indentification as well. If not, how is it showing up?

Hello,
yes in device manager it shows up as "LGE AndroidNet USB Serial Port (COM6).
My G2 is exactly stuck like the one in the picture you've sent.
I thought i could try this solution on ubuntu:
http://forum.xda-developers.com/showthread.php?t=2582142
But it also can't fix it, because when i plug my G2 in, ubuntu says: "MTP-Device could not be read."
Thanks in advance!

how you repair LG G2? My phone was not rooted, but today make offical LG G2 Lollipop update, and now have this problem. Stuck in Firmware update..

Problem solved warranty service. Update KitKat soft, but no't have offical info and lollipop update. I don't understant that LG Suite have yesterday update.

Same problem here,
my LG G2 D802, unrooted phone with official 4.4.4 got message to update it to lolipop, and I am now stuck on Firmware Update screen.
LG Mobile Support tool, was showing that I am making progres, but on the status bar i got stucked on 32%, then I started again, and then got error on 40%, then started again through LG mobile Support tool and got to 50%, and the same to 60%, then 70%, and this last time i am stucked on 92% and my LG Mobile Support tool forced close.....
And now its downloading again update, and maybe now it will go with all 100 %, dont know what to do.. this is so....
I thought it was driver related problem, but i changed machine, from pc to lap top, and the same thing is happening..... Every time it stops, first it writes on mobil screen with red letters ASSERT
and on status bar on LG MST it freezes, but as i sad, every time i get more % very strange

Same here - unrooted stock KK d802 - started doing the update, it failed, now stuck on the firmware screen with no way out...

i had the same problem, after several times i gave up and tried kitkat to revert back. Errors kept going but after several times it reached 100% and i am in kitkat now. I will try again today.

Yup, its probably somethnig wrong with the software that they rolled up to us.... after 10th time, it reached to 100%, but know i am stuck without network and signal,
and I get error messages "proces android.com has stoped" on every 3 seconds, I am losing my mind here realy
Do not update it, just wait for a few days, until they fix this
This is first time in my life, that I bought android phone, and that i didnt touched it, unlock it or root it, and with offical update i am having problems that i never had with custom roms

Mine was like yours . Ya I skipped the backup and thought it was a breath and it got stuck and tried to update it but every time the percentage increased so after so many times it did update... but it ended up wiping my phone .. no photos no nothing .... i guess looking for a good rooted rom is as good as any... this sucks
Can you guys suggest Lolipop roms which are rooted and as close as possible to stock rom ?

Help me pls if anyone has a solution pls

pls help

Don't know if this works for anyone else but...
I got mine stuck on the firmware screen because I was holding the volume up button while it was booting up. So I removed it from the computer and took out the battery. Then I put it back in, booted into recovery mode and rebooted to bootloader. It went to the lock screen and I didn't lose anything.

Help
I have a similar problem, my phone is stuck on 0% Firmware update and says in a little box: 910K B100. I have tried powering off but it doesn't work. Please help.

[HELPP] H918 is stuck at a bootloop and I've tried everything!!

I've searched far and wide for an answer to my problem and I've returned with nothing. It's been almost 24 hours without my phone and I think I'm losing it. I've downloaded and tried LGUP (alongside Uppercut), LG FlashTool 2014, LG Bridge, LG DLLs, etc and nothing has worked to flash my phone to stock with the KDZ. The closest I've gotten it to work is with LGUP but stupid me, I managed to edit the buildprop before it went self destruct and changed the device identifier to a Google Pixel XL and LGUP refuses to cooperate. Any help is appreciated. Please. :good:
I've managed to get into fastboot. I'm sure I can do something from here but idk what to put. Any help is appreciated once again

My guess is that you're rooted considering you've edited the build.prop? Why not enter recovery and flash a stock rom?

Can you not get into TWRP?? I believe its the same way as everyone else..\
Hold the volume down button and the power button and as soon as you see the LG logo left go of the power button and press it again. This manual step is a pain in the arse, but it will get you there eventually. Since youre rooted, you also get the "This device is corrupted screen" yes? The LG logo popup you are looking for is right before that.
What I do for easy and fast access is this. I keep the back cover off and hold the volume down button for ease. I hold the power button, let go, and press it again and ususally that first try doesnt work. As soon as I see the corrupt screen I take the battery out very quickly and put it back in and repeat the process. After a few tries the LG logo will hang before the corrupt screen and that gives you the time you need to let go of the power button and then hold it again until the factory reset screen comes up. Just hit yes twice... It will go into TWRP.

Well with the corrupt screen, it seems that the time frame that would allow you into Recover/TWRP is shorted. So pulling the battery after trying usually gave me more than enough time to boot into it. Probably not the best for the phone though xD

[HELP] S7 edge G935F bricked

Hi Guys,
After trying to start my s7 edge, i have got a frozen screen and bootloop to samsung logo... Blue light still like this and Green light flashing slowly behind the blue light.

I tried to boot recovery again, same issue... I didn't install new application or something added to phone for more than 2 weeks, from then i haven't observed issues with my s7 edge.

I tried back to flash it now, but with my 7% low battery, i couldn't hope more than this ! i'm letting it charging now until his 100% then i'll retry to flash it.

It doesn't charge or shows any sign of life... what the hell! what must I do???

The best solution for that is bring your phone to samsung service center or wait for other member reply in this thread. Maybe some other could help you with your problem. Anyway i'm sorry couldn't help you.
Did your phone is rooted before? Its strange that happened to your phone. Or did you flash anything or something in your phone before?

Hi man,
Thanks for the reply.
I didn't flash berfore or tried to root it. i just used Lucky patcher for non root user.. don't know what it could do to the s7 edge knowning that it hasn't privilege to change anything in the software of samsung.
Problem with samsung warranty, is that about 10 months ago s7 edge felt on the ground, got back cover little bit broken. so the local shop told me that sure they will ask for reparation because there is a crack behind the phone so certainly that the issue comes from the crack... so i think i'll just repair the cover and send it properly to samsung, 'cause it stills under warranty.

i've got him back but problem is when i launch the odin flash, it reboots the phone and makes a fail for the flashing rom... it does a bootloop...

I'm not sure bro but sounds like your eMMC phone is broken that's why you're not allowed to flash firmware. But try to contact other expert member here try to send a pm message maybe they can help you out.

I have had similar issues.
If the phone does not react to any pushing of buttons, I suggest you completely let the battery drain. Just leave it for 28 hours without charge. Then charge and try again.
Second, if you can get into download mode, use samsung smart switch and or Kies to get emergency firmware recovery going. This also worked for me.
If the phone does not react after powerdrain and recharge, hand it in to a service center.

I did it. It works to drain it and recharge so i have flashed with the official nougat firmware but then bootlop at samsung logo. When i tried to force reset it. It came bacl to the blue light so now im forced to wait until it ďisappear and then recovery mode to see if i can access into it

Sorry if I am over simplifying but it is important to be very accurate. As you state that "you" flashed the nougat software? Sounds like you used odin or
Did you:
1) Put your phone in download mode? (not recovery)
2) Did the PC recognise your phone?
3) Did you use Samsung Smart Switch on the PC?
4) Did you use the Menu in Smart Switch on the PC: "More", "Emergency Software Recovery and Initialization" option?
5) and then choose Device initialization
6) Input your model name exactly (on the back of your samsung eg SM-G935F?)
7) Hit "OK"
Let me know what happens

I'll try it this evening, because 100%'s battery to drain take about 28hrs like you said.
Hopefully your method will work for me

X727 LePro 3 stuck in Recovery Boot Mode. Not Rooted, have access to Fastboot

Hi all,
I was wondering what anyone can tell me about the problem I've got with my Le Eco Le Pro 3 phone. So, I had access to the phone before I jammed both the volume up and down buttons, which caused me to go into fastboot mode. Initially I would get the trusty ole platform tools and just "fastboot continue" the phone into the regular boot. It worked the first time, but I guess the volume down button was still jammed and I got myself into a little bit of a loop. Now, instead of going into fastboot mode, I go straight into Recovery Mode, which I've had to translate because it was in Chinese. The two options I have in recovery mode are to "clear data and do a factory reset" or "install an update.zip". Now, I instead opted to exit out of Recovery mode by pressing the bottom left option, but it just boots back into Recovery mode. I haven't rooted the phone and I have no usb debugging enabled because the issue sort of popped up outta nowhere. Initially, I probably should have just backed up all the data on the device and not had to go through any troubles, but that's why I'm making this post. I would also like to further note that I do have a lockscreen code, so if that "encrypts" the data (making it harder to get to, I guess) is my only guess.
I read on another thread where I can essentially unlock the bootloader through fastboot mode and then be able to enable USB debugging that way and maybe manually remove the files from my phone and just factory reset it to see if I can get the phone running. I also looked into just straight up factory resetting it, but I would probably have to root it before I do so that I can run a third party tool to get the data after the reset. I'm also quite new to this whole issue but I'm stressed and straight out of options.
I would also like to note that there was a blue light when I had tried starting the phone on the upper right hand corner where it would indicate the battery level. The whole recovery boot loop could have been caused by a battery malfunction, but I do get a response from the device in fastboot mode (so I think the phone is not entirely dead). It also charged up to 100% without issue.
Basically, I just wanted to see what anybody had to say about my problem and if you all have any advice (like how do I backup a phone that is not rooted).
Many thanks in advance.
I've also posted an image with the recovery mode

Did you try to fastboot boot TWRP?
Sent from my ONEPLUS A6010 using Tapatalk

The phone doesn't have TWRP and has stock ROM. Installing TWRP would require me to OEM unlock it and then flash the current bootloader (thus replacing the original recovery boot). Unless I'm completely wrong and there is a way to install TWRP without losing the data on the phone, then I would love to be enlightened because I'm at my wits end.
I tried charging it to 100% and restarting it but it just leads me to the recovery screen. I'm not entirely sure if the phone volume buttons are still jammed, because that could still be the case.

Fix the buttons the phone should boot
Sent from my ONEPLUS A6010 using Tapatalk

Alrighty, so a little update. I got the phone's buttons removed but it still boots into the recovery mode. The metal button on the side was removed but the button module remains. It's just not jammed any longer, which now begs the question: Why is it still booting in Recovery mode? I am currently charging it to 100% to see maybe it could be bugged with the battery, but that is the update so far. Button module is no longer jammed but we are still booting into the Recovery mode.
Any suggestions would definitely help in my 2 month long battle with this phone.
Btw, I also replaced the screen because the repairman who removed the buttons broke the original one and the new screen responds to all touch.

poco m3 does not turn on anymore

I recently updated my Poco M3, it updated correctly but after that, it doesn't turn on anymore, I searched about it and I found that it was a problem with the update. I managed to turn on my phone again by pressing 13 seconds the power button, after that, I received a new update so I thought the update fixed that but when the phone rebooted to install the new update it doesn't turn on anymore. I've tried to enter fast boot mode but doesnt't works.
I don't know what should I do, I've tried again to hold on the power button and I also tried to enter fast boot but as I said it doesn't work. Also when I plug my phone to charge it, nothing happens
I hope someone can help me, and sorry for my bad English.

you need to drain your battery first. same happen to my poco m3. after that you need to flash your firmware or else it will happen again after you reboot.

And how can I flash the firmware? I've tried using the Xiaomi Flash tool but it asks me for a Mi account that is valid for the process.

Drain out your battery and then just plug the charger then wait.
I had this happen to me 2 times now,it would take days if your phone fully charged like mine,it takes 5 days.
After that,
make sure to backup your phone,unlock your bootloader and then re-flash the stock rom with Mi-Flash or just use another rom to your liking.
The truth is I like the stock MIUI than any other rom but if this kind of problem keep happening,I rather just flash another rom.
Hopes this help fixing your phone,sorry for the rant there.

Biggest problem with this phone is , there's no way to force reset the phone. I literally tried everything from vol up + power and volume down + power and everything else Buying this phone is prolly one of the biggest regret of my life. And the youtuber xiaomi slaves didnt help. But my real question is.... Will flashing custom rom fix this problem?

And the youtuber xiaomi slaves didnt help. But my real question is.... Will flashing custom rom fix this problem?

I recently updated my Poco M3, it updated correctly but after that, it doesn't turn on anymore, I searched about it and I found that it was a problem with the update. I managed to turn on my phone again by pressing 13 seconds the power button, after that, I received a new update so I thought the update fixed that but when the phone rebooted to install the new update it doesn't turn on anymore. I've tried to enter fast boot mode but doesnt't works.
I don't know what should I do, I've tried again to hold on the power button and I also tried to enter fast boot but as I said it doesn't work. Also when I plug my phone to charge it, nothing happens
I hope someone can help me, and sorry for my bad English.

It did happen to me and I did pull the battery connector even pull the display connector while doing it.I read a post on reddit about it,pull the battery and display connector and then try connect it back while pushing the power button,the guy said the phone did turned on but whenever he tried to restart,phone would not boot and he would repeat that unplug,plug,hold power thinggy .I did try the method but nothing happened.Plug in to pc would only detect it as in EDL mode,with a locked bootloader theres nothing I can really do as flashing it would only met with this and that error.Then I read someone on a forum said to just let the phone fully discharged and try to plug in charger and wait for the battery empty logo pop on screen then the phone would boot as normal.It did work for me but I gone through nearly 5 days as my phone was fully charged.Its been like 4-5 days now and eventhough I already downloaded the latest ota for miui global,Im still dreading to install it as Im afraid the same problem would occurs again.Maybe I should unlock my bootloader first so the next time my phone goes EDL mode again,things would get easier to do.Sorry if this rants of mine a bit too long.

i did a factory reset.... but the phone didnt turned back on. i did do the ota update three times prior to this one which failed three times. .. the first one prolly broke the recovery and fastboot mode ... im not sure what to do after this. since i cant go to recovery or fastboot mode. this is prolly the first time i experienced this. where the ota itself which is supposed to make the phone better broke the phone. it will prolly turn on after it got drained but im not sure how to update firmware without recovery or fastboot and yes this is a ****ty phone and company alright. i send my logs to xiaomi. and still no response from them.

tnx sa share boss malaking tulong

when i heat ( about 3 to 5 sec. or more with soldering iron and flux) camera power ic under ( Power Control IC PMI632-902 ) the phone boots up
HCBE AKD written on this ic
in some other m3 phones that text is different
it has 4*3 pin under lower left side of shield
phone boots up with this method one time
if you use flux phone will be good till 1 hour power off then problem comes back
i neeeeeed schematic diagram of this phone's motherboard...
in some cases when you unplug battery
then short circuit with power key
then plug pc usb till flashing screen
after that i connect battery with holding down power key and usb connected
phone powers on from edl mode to normal mode (in some cases lcd flashes in some other battery icon shows rapidly and gets off)
ow in cit mode #27-charger test some phones we have red text battery test fail insted blue text that ask reverse plug usb type c connection)
is there another test or somting else???

no just edl mode

Poco m3 drains battery by itself. General rule of the thumb
1-10% - 0 to 1 day
11-20% - 2 days
Basically 1 day is around 10% of battery
I think the motherboard is on but for some odd reason the display board and basically the whole thing doesnt turn on on. But it still is draining battery even when turned off. Removing the battery doesnt fix it. I tried several times
