I own an LG G2, i recently got this phone yesterday from a person on craiglist. Don't worry i didn't pay him i gave him my older phone i dont use anymore. SO This phone is practically stuck in Firmware Update (As i read that post) , i spent about a day and half figuring it out and what happens is that.
I CAN get into recovery its TWRP v2.7.0.0 by Turning off the phone first and then Holding Vol UP, Power, Vol Down at the same time until the LG Logo comes up and then i am still holding them down, and it says Recovery Mode please wait and bam TWRP.
But heres the problem i can't mount my OTG and i can't ADB Sideload. So what do i do from here?? this guy rooted this phone and soft bricked it i think? and he wiped the phone but i also did when i had the chance and wiped it completly via recovery.
The only way i got into "Download Mode" / "Firmware Update" was to take the back cover off and unscrew a few screws on the side and unclip the battery for a few seconds and then plugged it back in and then I held the VOl UP button and plugged my USB into the phone and the other end is in my PC. My phone says "Download Mode please wait" and then prompted with the Firmware Update screen. BUT my pc doesnt detect the phone whatso ever and i've already installed drivers and etc from this forum ( http://forum.xda-developers.com/showthread.php?t=2432476 ) its the 2015 method that i downloaded.
so what do i have to do, i havent tried using different usb cables, the port seems fine to be plugged in since in TWRP it says 84+ so i meant its charging right? help me out guys idk what else to do or flash or anything.

I think the methods leave out that you need to change your phone to com port 41 on device manager > ports in order to be detected. Then you need to unplug it and reconnect to computer when the program shows waiting for device, with the phone in download mode already.
Also, to get to recovery you hold vol down and power, when the LG logo comes up release power and hold it again until the reset screen comes up.
To get to download mode you turn the phone off then hold up while plugging the USB cord in with it connected to pc... This launches download mode.

Well you see man , I cant change anything in Device Manager since my phone isn't being detected. It didn't install drivers fully fully since my phone isnt recognized. Even in TWRP or "Download Mode/ Firmware Update" Nothing happens no drivers installing or anything even but it does boot it up to that point....and its just normal boot up i see the LG logo and my led goes from green to blueish in a smooth transition and it doesnt stop until i turn it off. The method i got into recovery is holding all those buttons down its not a problem for me to get into it. I also have another problem it doesn't seem to want to mount my usb otg by samsung.
what do i do
So i tried the otg route but I can't mount it. I have everything connected and once I go into recovery to mount usb-otg, nothing happens.
I just need some way to get a ROM.zip in my phone
Computer does not recognize my phone.
Stuck at LG logo unless I enter recovery.
Sideload doesnt work.
OTG doesnt work.
I've tried at least 4 different guides with no luck.
Why don't you manually install drivers from online?

ive tried that already and it doesnt list anything from the LG folder.
I realized the phone will say start the adb sideload feature. so, when i put the "abd sideload file.zip" command on my pc i just wait a few minutes and it says daemon not running on port 5037 and then start successfuly and then error :device not found.
it can seem to reognize my device wether its in recovery, or download mode or fastboot mode.
Try again in other pc that has never been conected to an LG Phone before. It can perfectly be a conflict with drivers installed in the OS.
I've tried man
AFter i cleaned the usb port in one of the chats or forums, i waited a day ovbiously without turning on the phone and cleaned the usb port with alchohal and a q tip and i plugged my phone into my computer and my PC detected something but it only says "Unknown Device" everytime no matter what pc i use it says that. nothing else. but before that none of my pcs would detect theirs a phone plugged in at all.

Yesterday i flashed my Jiayu S3 to lolipop (i tought) and i just bricked my phone!
After reboot it was just dead.. when i plug into pc with USB i hear the connect sound and after 2 seconds the disconnect sound. This keeps on going until i pull the USB plug. When i look in DeviceManager i see it refresh after every sound, but nothing pops up (unknown device or whatever). I deletet all usb drivers with usbdeview, restart pc but still no changes.
I tried with or without battery, but without it does nothing at all.. i tried holding Vol+ or - or both or with power button, but nothing.
Read some threads about unbrick and install correct usb driver for jiayu s3, but all the options they came with does not work on my device!
I'm a little despered now and don't know what to do.. i get the feeling that my 2 weeks old phone is dead? :'(
My pc has windows 7
Did the flash with SP Flashtool 5.1516
Did not untick preload in flashtool, i guess i got the wrong preload or something??
Please help!

Just flash it again, but this time with "Firmware upgrade " in SP Flashtool instead of "Download". Change from KK to LL needs reepartitioning, so firmware upgrade.
The reason why you don´t "see" the S3 any longer on the pc is, that the USB storage mode from KK, which is driverless for windows, don´t work right now on LL.
Once flashed to LL you will need to install a driver, for windows to connect to the S3.
@ Dior DNA:
No i can't. Phone does nothing with the buttons. Only diference if i hold Vol - then time from connect sound and disconnect sound is a little longer.. about 10 seconds. But still nothing happens.
@1testi:
Flashtools can't see my phone. I tried it a hundred times. With battery, without battery, with Vol - and with Vol +.
When i connect the USB cable i hear the connect sound and after 2 a 3 seconds i hear disconnect sound. This goes on and on until i pull the USB cable out. In devicemanager i see a refresh going on, but nothing pops up.
I'm realy despered on what to do now?

Why the SP Flashtool isn´t working any longer? You didn´t deinstalled the driver, did you? Just try to flash again with "Firmware Upgrade".
I don´t know a way to reinstall the driver in windows without the preloader. The only thing you can do, as far as i know, is to use a linux
pc to flash again. Linux don´t need a driver for SPF, only some rules.

Booting into recovery or flashtool I meant regardless of pc and/or spflashtool.
If I recall correctly:
hold volup and power boots recovery
hold voldn and power boots flashtool
If you can boot recovery then which one is it? Maybe you can restore something or manually flash preloader bin from there.
After the flash i reboot and then the connect and disconnect sound appears. So i tried differend things, but could not connect. I wanted to flash again, but flashtool did not reconice the phone and nothing in DeviceManager. That's why i thought to remove the driver and try to re-install it. But that did not help..
Holding Vol - or + button with power button or both Vol buttons with power button does nothing.. i tried to hold all combinations at least 30 seconds, but nothing at all.
I have no Linux pc or any knowhow to make a Linux pc.. or a pc to install Linux on..
One last thing you can try: remove the battery, wait a little, insert the battery again. Hold vol+ key, keep holding it and press power
button, while still holding the vol+. If you don´t see anything happening then you bricked the phone.
You will need help from a professional or at least from someone with a linux machine, sorry.
I'll try that.
You have any idea what could have caused the brick?
As i wrote above, moving from KK to LL with wrong parameter "Download" in SPF.
....and a not working recovery.
You should try this method :
darmowyinternet.net/forum/temat-poradnik-jak-uruchomic-uceglony-telefon-po-wgraniu-zlego-romu-test-point_383
unfortunately you have to translate before
Ok i tried that site with google translate and i could a little make up what they are saying.
But that is a very drastically operation, and i would like to give it some other tries before dismantling my phone.
So i googled and googled.. came here: http://forum.xda-developers.com/showthread.php?t=889128
Had enough electronics lying around from my former 27mc hobby, so searched for the right resistors,
cut up a micro usb cable and give it a try... well.. nothing! Tried for about an hour and gave up.
Then i googled on Unbrick Jigs, but for what i read they are only for Samsung phones, so i gues the trick
with the resistors were also?
So googling again... came here: http://forum.xda-developers.com/showthread.php?t=2454004
Reading the tread and the comments, someone mentioned a download for "Mediatek Driver Auto Installer".
Downloaded that and installed the drivers. Plugged in my phone and... whoohoo!! Something is happening! :silly:
My devicemanager saw an "Alcatel single RNDIS interface". I unplugged and plugged my phone a few times to
be sure it was my phone. Sooo... one step further! :good:
Then i googled on this device.. came up with all sorts of network devices, not helpfull. Then googled on Jiayu with
this device. Came up with this tread: https://www.china-devices.com/topic...vcomm-drivers-onto-your-pc-win-7vistaxp-only/
It's a tread about bricked Jiayu G3 devices, but i thought, 'What the heck, lets give it a try!'.
I downloaded the "MTK Megapack - All Tools Here!" and unpacked. Wend back to device manager and manually updated the driver
of the Alcatel device. Show all devices - browse - wend to Megapack map and there were MTK drivers for the 65xx device.
And yess.. when i plug in my phone there's the device: " MTK USB Port (COM7) "
SP Flashtools sees my phone again! :good:
Tried to flash a stock preloader, but got an error: "BROM ERROR : S_FT_ENABLE_DRAM_FAIL (4032) – [EMI] Enable DRAM failed!"
But for now that's a problem for tomorrow.. it's almost 2:30 and i have to got some sleep!
(sorry for the misspellings or telling things not clear, i'm tired and english is not my main language)
Grats!
You can google the error. This leds you in the right direction.
It's alive!!!!!! :laugh::silly::victory:
Because the kitkat stockrom i downloaded gave me the same error over and over i searched for something else.
So i downloaded TF Extreme lolipop 5.1 this morning and give it a try. And all went well. I pulled the usb plug and
pushed power button.. only vibration but nothing. Then pulled the battery and after few seconds put it back in
and try power again. Only 1 vibration.. then tried Vol + and - combinations but nothing. (dammn!)
Then plug the usb in and i saw the battery icon.. it was total empty! (because of a week trying).
So now it's charging and i hope it starts, can't wait!!
Thanx all for the effort in helping me out! :good:
Edit: Ok, so i could not wait and hit power! It shows green screen with Jiayu S3 logo and text "New Load". So i guess it's prepairing for first startup!
my s3 basic is not charging when on.. also when connected to pc thru usb, ipc shows device malfunctioning ,and there is no indication on phone..I try to connect to sp flash tool also no success..same error"usb device not recognized pops up every 2s.everything else is fine..Any method to upgrade to 5.1 now on official kk
Kinda need help, happened something similar
It happened something similar to me.
I flashed the whole ROM, bootloader included, I was very sure that my model, Jiayu S3 3GB ROM + 32GB RAM, was the correct, but still bricked my phone.
There's no problem at all when I plug it into my PC, I installed the lastest MTK drivers on windows 10, having to disable the signature enforcement.
The problem comes when I start flashing. I only mark the bootloader, then I press "Download" (on the lastest version of SP Flash Tools), and plug the phone, with the battery in it (I've tried without battery, pressing all possible combinations and does nothing), when I plug it in with the battery and pressing no buttons, the driver is detected as MTK USB Port. That's a good thing I guess. But It does not pass from the red bar, and gives me the known error "Enable DRAM Failed".
I've tried to google any possible solutions, reinstalling other version of the MTK drivers, on different versions of Windows, with other versions of official ROMs, and the result is always the same.
The only thing that's left to try is flashing it with an Ubuntu machine, which is something I do not expertise to be honest, but I'm gonna gather some info and try to do it.
However, if someone has any idea of what I might be doing wrong (excluding the part when I flashed the bootloader, I'll never do it again), I would be really grateful for any kind of help.
Thank you!

Are you sure you disabled driver signature enforcing in Windows? You can't install the qualcomm 9008 serial interface driver without doing this, as this driver is not signed by Microsoft.

yes i did still it doesn't work, any help would be appreciated
If you power up your phone using volume up in fastboot/bootloader mode and then run fastboot devices, does it list your phone? Just making sure the cable connection works.
If yes, then power down your phone by holding power button until screen goes black (making sure you disconnected usb cable first). Then hold volume up while connecting usb cable (don't touch power button), you should hear Windows detecting a new device, check device manager to see that the qualcomm 9008 usb serial port has been successfully installed and with no warning exclamation mark on it. If all is good, you should now be able the launch the download tool and push the download button to start downloading the file partitions to the phone.

Could it be that the actual screen is dead on your phone? But still, since the PC detects the debug port, it should start restoring the phones partitions when you start downloader tool and press the download button up to the left.
Background:
OnePlus 8 Pro IN2020
Original OS version is OxygenOS 12 Android 12
How my phone turned into brick:
Try flashboot unsupported TWRP and other third party recoveries.
After a few tries, eventually causing my phone turning into a brick
What my error looks like:
Not able to boot into system
Showing "the current image(boot/recovery) have been destroyed"
Can access fastboot and detect by system
Method:
Follow the steps in How to UNBRICK OnePlus 8 or 8 Pro! by Max Lee (Thank you my man, Max, for this video)
Pitfalls in 2022 (IMPORTANT before UNBRICK!):A USB 2.0 and Third-party USB cable are highly recommendedI was unable to boot into Quadcomm EDL mode while using the stock cable and USB 3.0 connector. Pressing the correct Volumn Up & Volumn Down and Power Button will boot the phone to fastboot in no time.
I successfully got into the EDL mode and finished flashing the phone using my iPad Pro Type-C charging cable which is an USB 2.0 one.
Use a newer version of the Qualcomm driver if you find the device not correctly detectedUse Qualcomm HS-USB QDLoader 9008 driver.
A new Quadcomm driver will help you flash your device correctly the first time!!!
Windows 11 won't let you install unsigned driver by default, but there's a way round
Press Shift key while click Reboot in start menu to enter Advanced Options
Click Trouble shoot in Advanced Options
Click Advanced options, click Startup Settings then click Restart
After restart press 7 when required
If your computer won't restart, just unplug your phone temporarily
after this your device will detect by your computer correctly.
Pressing buttons requires special timing and preconditions and a few more tries
To fully power off your phone, press Volume up and Power button for 10 seconds. Release immediately after the screen turns black.
Your phone is in the state of powered off even your screen displaying error message or charging animation, just make sure it's not in fastboot, recovery or booting animations.
Connect your phone to your computer before press Volume up and down and Power Button all at the same time to enter EDL mode.
Prepare yourself with Device Manager and MSM tool open and configured correctly before your phone enter EDL mode. There's a about 10 second window for you to start flashing.
Fail amid your MSM flash process:Don't panic if you see error message saying you didn't finish flashing
You can flash it anytime just make sure checking all the things above and enter EDL mode
Check these things：
Check your Windows can install the unsigned driver correctly
Check Device Manger in Control Panel if your device is correctly detected as a COM device as Qualcomm HS-USB QDLoader 9008 or something like this
Use administrator privilege to open the MSM software
Check your cable connection is stable or not.
Finally, thanks Dr.E (Max Lee) for your help. Without your video instructions, I won't revive my phone. It spares my pain to ask my dad for money for a new phone I don't actually need.
Hope everyone could find some helpful information in this post and flash your phone like a champ.
A even better way to enter EDL mode is power off and unplug your device, and after hold volume up and down at the same time, plug in the USB 2.0 cable to the computer. It works every time!!
i cant join rdl mode always restarting fastboot mode
So I wanted to flash evolution X, which flashed ok but would only boot into fastboot mode. I then went to flash stock 11 rom using the fastboot rom. It flashed ok but when it came to rebooting, the screen just went black. I cannot enter fastboot, recovery or EDL mode. Regardless of the method to get into EDL mode, the computer wont recognise the phone. Device manager doesnt show anything being plugged in and MSMdownload tool doesnt recognise it either. I have the drivers already installed so the computer should recognise it.
What i did one time was:
Start MSM Tool and press start.
Connected the phone with a third party cable and to a usb hub.
Held vol up, vol down and power button for like a minute or longer.

You likely just haven't installed the proper drivers. You need those Qualcomm ones so your PC recognizes the phone. Also try different USB cables.
