[Q] NEW TO LG (Spectrum) - General Questions and Answers

Can anyone tell me where to find the fastboot drivers (win7 pro)
and how to enter fastboot mode?
I tried pwr+vol-down and got hard reset menu
pwr+vol-up rebooted to normal OS
adb devices does return
the serial number and
normal functions work
at regular boot mode.
I'd also like to know to reboot into recovery
[I did successfully use adb reboot recovery,
but hoped there was a button push to
enter bootloader or recovery]
adb reboot-bootloader and
adb reboot bootloader both
just reboot to normal OS.
thanks

There is one more problem i cant use buttons on phone to set download mode or fastboot mode, bottons just doesn't work i tried many times and nothing phone starting normal. So to use download mode i use "tool samsung 300k tool"or to boot in with TWRP i need use commend "adb reboot recovery". I don't know how push this phone to boot in fastboot mode to unlock bootloader(vol up/down +power +home doesn't work).
I would like enable root to have posibility to overclock cpu etc. And i would like to install newer android 5.1 or 6.
So can you help me and tell me what to do step by step. The phone is branded maybe this is problem ?
1 more queston if i would like delete TWRP and back to stock what need to do ? Install orginal rom ?
Samsung phones use Odin instead of fastboot, fastboot are not exist on Samsung phones

TWRP recovery menu not showing

hi, im new in this android arena and this is my first time using smartphone so please forgive my noobness.
i want to root my phone Xiaomi Redmi 5A and i follow some tutorial on youtube where he told to use Minimal ADB & fastboot, TWRP, lazyflasher noverity and lastly Magisk.
im flashing my phone using this command on ADB:
fastboot devices
fastboot flash recovery twrp.img
fastboot reboot
i guess this is it so im rebooting my phone to get into twrp recovery mode by pressing volume up+power but it showed xiaomi stock recovery instead not twrp recovery.
so what i do wrong that i cannot get into twrp recovery menu?
please help me
Don't type fastboot reboot command after flashing, reboot to recovery manually

i type that command after the first try not working (without fastboot reboot command)
it still gave me the same problem even not typing fastboot reboot command
Is the TWRP flash successful?
Ensure that your mobile drivers are installed properly on your pc and that you've enabled USB debugging.
Now after connecting your device to the computer :
1)open adb
2)type adb devices, if it shows a serial number then proceed
3)adb reboot bootloader
4)fastboot flash recovery xxxx.img
After this, remove the USB and reboot to recovery by Holding the appropriate combination of keys.
If you reboot your device first, and then power off and reboot to recovery, you will still get stock recovery.

Z3 Won't start or enter recovery

Guys,
I need help. I'm struggling for the last 3 days trying to revive my phone with no sucess. :crying::crying::crying:
I managed to put a custom rom sucessfully, but i had to make a restore on recovery mode.
During the restore process some error ocurred, something like "something not mounted", i did'nt have the ROM to flash anymore. For no reason i decied do reboot the phone.
Now i can't enter recovery anymore and the phone is froze on the "Sony Xperia" on the begginig.
Since start i'm having difficulty with the Z3 driver for Windows 10. To enter recovery mode i tryed to adb reboot recover but my adb doesn't work.
It's strange..
if i type fastboot devices it's show.
if i type adb devices it's show's "no emulators/xxx found".
I need help, don't know what to do anymore.
TLDR:
- Frozen at "Sony Xperia"
- Recovery don't enter pressing Volume Down/UP
- adb devices doesnt' work.
- fastboot devices work
Thank you!

You have some choices to restor stock rom:
1) Try Xperia compagnon fron Sony ==> Software repair (not shure about the label in english version)
2) Use flashtool (google for it) and a rom (*.ftf) of your choice.
When you are back to stock, then you can install a custom rom again

Hey,
Sounds like a corrupted system, not too sure what happened with the recovery though.
Try this out:
1. You need the phone driver and the fastboot & ADB driver. You can get the Sony phone drivers from the Xperia PC Companion. You can get fastboot & adb drivers almost anywhere, just google for them or scroll a bit through xda.
2. Unlock your bootloader if you haven't done so already here.
3. boot into fastboot mode by completely powering off the phone then holding "power+volume up" and waiting until a blue LED appears in the top left.
4. Find a custom recovery, rename it to recovery.img, navigate to the folder that contains it in CMD (i.e. cd C:\Users\USERNAME\Downloads\Android) and type "Fastboot flash recovery recovery.img"
5.You should now be able to boot into recovery again. All that's left is find a ROM of your liking, push it to the phone in ADB and install it.
Hope this helps!

Phone wont go into bootloader. How to root + flash new recovery?

Hello. I can't get my phone rooted in any way.
I want to Root so I can use TWRP app to flash TWRP recovery .img, and after that I can boot into TWRP recovery and flash new ROM. Correct????
What I've tried so far. OppoTools 1.6.5 = One key root gets hard stuck on Oppo logo at start-up and then I have to flash Coloros ROM again from recovery. Also KingRoot says app not installed. On windows version of KingRoot it gets to some percentage and then it Fails.
I have downloaded "unlocked bootloader" Coloros from this forum that was mentioned before ( Dropbox link )
I have also tried two different ColorOs versions.
I have installed 15sec ADB installer.
I plug my phone into PC and run CMD.
I type adb devices into command prompt and it detects my R7 plus.
then I try to command " adb reboot bootloader "
Phone restarts normally and doesnt go to bootloader. Tell me if im stupid, but isn't Bootloader different than Recovery? Because I can get to recovery command "adb reboot recovery"
I tried some weird button combination Vol+ Vol- + Power and phone semibricked for awhile and PC didnt even react USB driver correctly and almost waved the white flag on this case.
I've enabled USB-debuggin and OEM unlock from devices dev-options.
When I to type command "fastboot oem unlock" on command prompt is says Waiting for device. Nothing pops-up on device and nothing happens.
So now Im stuck on situation that my phone doesnt launch into bootloader where presumably "fastboot oem unlock" would work?
If you have flashed the version of Color OS that has bootloader enabled, you should simply need to go into the settings, enable USB debugging and OEM unlocking, then shutdown the phone before holding the power and volume+ buttons and waiting the ADB bootloader screen. After that, just plug it into the computer and follow the guide on flashing twrp with ADB.

Phone can't enter bootloader

Hello.
I have bricked my phone(I edited build.prop). Now it can only enter recovery mode. I can access the phone by using adb, but I can't get root access in shell(but my phone is rooted), it just says connection to ui timed out, so I can't replace build.prop. I wanted to flash custom recovery on my phone, but when I reboot in bootloader mode using adb, phone just stuck at the logo(and when I tried to reboot in fastboot mode, the same thing happened, but at this time logo just disappeared after some time). After trying to enter fastboot or bootloader adb don't see the device. I have installed all drivers, enabled usb debugging(just in case), Phone model is Micromax Canvas Elanza 2(or Micromax Canvas A121).
So, my questions are:
How can I get root access in adb shell?
How can I load my phone in bootloader/fastboot?
And is there any another way to unbrick this device?
P.S. Sorry for my English and thanks in advance.
from recovery mode there should be a option "reboot to bootlader" this will bring you in download mode. while in download mode install the drivers (these are different from adb devices) and make sure "fastboot devices" does recognize the phone. now you can boot into custom recovery without flashing it "fastboot boot recovery.img". once in custom recovery again install drivers and then check "adb devices" while in custom recovery. "adb shell" will give you root access while in custom recovery
