Hey guys,
I have this error on my LG Optimus G E975.
Im well aware of the KDZ method of unbricking my phone but it seems that I always get stuck because it says "no phone detected"
Is there any way to check if my Windows 8.1 is being a pain or if my USB port is broken or something?
I hear the sound of the phone being connected when I plug it in, in download mode but any Flashtool says Phone can not be detected.
I saw a comment somwhere saying that as long as my computer detects it, I can push a ROM via ADB to it.
I have to idea what that means but would like to try it if it works. ANY ideas are welcome, ive been stuck at this for a week now...
Thanks guys!
Recently after trying to upgrade my LG G4 to android 6.0 by flashing the zips in recovery, I encountered a boot loop. I have tried many thing like using the LG Flash Tool, I also tried booting into recovery and restoring a backup I made, but none of this made any difference. Please I need help.
LG G4 H815 android 5.1.1 or 6.0 (not sure) I'm not sure because I tried to flash the zips fro android 6.0 via recovery and didn't work, then I restored my phone and tried to boot up but that failed to work as well.
Try to use the LG bridge tool.
Start lg bridge.
Connect your device while off with your usb cable.
It will start - nevermind, just keep it going.
Use the "solve update issue" option in the bottom right corner of the software update screen in lg bridge.
It will reinstall 6.0 without data loss.

It does not detect that the device is connected, even when it is.
Takes some time to detect. Worked for me an hour ago...

I might have fixed it using a different method.
Wich method?
I have the same issue.. I send my phone to the repair center of amazon. Let´s look what they can do.
Not necessary, in bootloop, just connect usb and start lgup, when it detect it, (and it will as unknown mode device) tap com port it was found on and ui will open, then click on phone info, it will connect and establish a valid usb connection to phone and open new prompt with phone info...... Then start adb command prompt and enter 'adb reboot recovery' and bingo you're in recovery.... Solves every bootloop!

If the phone in bootloop, such phone does not see any one program
This phone can be started only in the DM

my LG G4 has factory bootloader and after resetting it im stuck on welcome screen - can't move pass it without wifi - because the wifi is chip is dead.
apparently - i have connected the device with USB but its not showing up on adb devices under any mode.
any idea why that is? how i can get it connected so i can try other ROM. :crying:
Greetings every one ..
I have a half dead Oneplus 3 Unlocked + Rooted
here is my problem
there is no OS in it and i flash TWRP many times via ADB and wont boot to it
and i tried to flash the stock recovery V2.0 and done successfully
the sideload mode Recognize my OP3 but when i try to flash the Oxygen Rom it Gives me cannot read
also i tried the Unbrick Tool when the device is connect it showing me Qualcomm hs-usb qdloader 9008
but when i power up the tool as administrator it showing me (no device)
see here : https://www.youtube.com/watch?v=BIbagVAXJJk
Thanks .
on the unbrick guide try method 2 but completley power off the device and count to 10 when holding the vol up button THEN plug the device in. i had that issue also. if you get errors or for some reason it dosnt show up again try on a diffrent pc it will work
Try method 2. BTW "cannot read" error has to do with faulty ADB drivers, get the platform ones
I did instal the right ADB drivers in fact
still no luck
The ones from platform tools? Since that "cannot read" error has nothing to do with your device. Have you tried renaming it? Rebooting your PC? Last one did wonders for me for some stupid reason.
Hi,
I also had this message of "can not read" in sideload mode, this problem often happens with Windows 10, so I used Windows 7 on another pc and it was OK.
I tried Windows 10 & 8.1 & 7 & XP
still The same problem
What if you flash Twrp and boot into it? Then u can adb push the filemm
I tried via fastboot and its done right
but when i reboot into the new TWRP recovery its stuck in the boot oneplus as same like the Video shown up
book an appointment with oneplus live chat so a service tec can fix it and if they ask if it was rooted say no
Hi,
If you access TWRP, install the Official Oneplus Recovery 4.0.2
In TWRP click "intaller" then choose "install image" and select the file you will have to copy to the phone in recovery mode.
Then restart in recovery mode, choose english, then "adb sideload mode"
From there you should be able to flash your phone with an official Nougat zip.
Do the under windows 7.
It is necessary to install the Oneplus USB drivers and ADB tool on your PC before any manipulation.
Finally I solved the problem
like i said B4 my phone wont boot into TWRP by any chance
i traid all the Officials TWRP one and they stuck on the boot image or power the phone off
i flashed a modified twrp (blu_spark 3.0.3-x) thanks for this beautiful smart man eng.stk if im not wrong
and thank you all for the help
i had similar issue...with several phones.. download Malwarebytes trial version and run it...i had a few stealth root tool kit viruses.causing my system to have a hiccup....
Hello guys!
Today i make a big mistake. I want to install CM 14 to my LG g3 . At first i can't go into TWRP . After 1 hour a somehow managed to boot in twrp but after formating the old os the phone is not responsing at all.
Things that i try:
I try to install a bootloader with ADB but the my pc cant recognise the device.
Things that the phone does:
There is no boot screen all it does is led and blue LED is blinking.
If i connect to the pc it recognise it as "Android " but i cant do nothing with it.
Please help me. Thank you
Did you try to connect in download mode and flash stock firmware with the official toolkit? I don't remember it's name though

Yes of course but the pc diden't recognise the phone and it say its " not cot connected"
You need to install device drivers and ADB drivers before trying. Use USB 2.0 ports too, it's acting wired with 3.0 ones
