I'm trying to delete userdata using fastboot, but this command "fastboot erase userdata" gives me okay reply, but when I reset phone, the userdata is still there. Any ideas?
Fastboot operates on phone's bootloader, not on Android OS where user data are stored in.
Use ADB to remove user data.
fastboot commands disabled on locked bootloader. post full output pls
Wrong: on devices that support fastboot you after having turned on OEM unlock you e.g. run
Code:
fastboot flashing unlock
to unlock its bootloader.
right. fastboot boot format erase flash are forbidden in locked state, to be nitpicky...
unlocking bootloader will perform factory reset, therefore it is protect by OEM toggle in developer options, too.
the phone's Bootloader is unlocked, and I can't do anything else with the phone when it can only fastboot. I can't even normal start phone to go into ADB.......

Re-flash Stock ROM, and if successful immediately enable ADB.

So I used Rumrunner to get S-off but for some reason I got into a boot loop. I searched the forums and it seemed if I flashed a rom it would help fix it. I flashed Magio rom but here my problem. I can get to twrp I can mount my phone as well and adb recognizes it when its mounted I can push files and can flash roms but I cant seem to get fastboot working to flash boot.img in the bootloader it says fastboot usb but when I do adb devices it only shoes list of devices attached

Hi
After doing a hard reset on my phone, he fought on the screen with the logo of Motorola and will not start.
I've tried reinstalling the stock rom , but I could not because the mfastboot shows the following error ...

As your bootloader was locked i don't think them partitions can be flashed how ever you should be able to still flash the system sparse images as if you have done a hard reset on your phone the partitions your trying to flash wouldn't be effected anyway.
Just go into bootloader they and flash just the system sparse images then boot into recovery if you can and erase the cache.
The bootloader was never unlocked. The problem may be that I'm trying to install the ROM 4.4.4 first? Think if I try 4.3 or other older versions it stops to present such errors?
Did you update via OTA to 4.4.4 if so then you must use a 4.4.4 image. Bare in mind you'll need to use the Right CID numbered frimware.
Have you tried to flash the System partition i.e the system system.img_sparsechunk.0 - system.img_sparsechunk.3 , give that a go.
I tried to install the images of the system and it still fails.
I do not know what to do.
Hi
Guys I need your help.I wanted to upgrade from Stock kitkat 4.4 to Marshmallow.
I started with rooting via LG one click rooting.After rooting successfully I tried flashing TWRP recovery via TWRP manager but it didnt worked and instead of going into recovery it kept going in fastboot.
I tried flashing recovery via fastboot also but no use.Then I tried to unroot via LG Flash tool using download mode.But unfortunately It gave an error "[ERROR] Partition change error".Now I am not unable to get out of download mode.I tried deleting laf file and I came out of Download mode but now I am stuck in fastboot mode.Now if I try to flash anything or erase anything in fastboot it got stuck on erasing or writing.If I run 'fastboot devices' in fastboot it show "? fastboot".
Please help.I know I have messed up but any help would be appreciated.Please help me get my phone get back to life.

Yup.mine g3 was also stuck in Fastboot.and I couldn't execute any command.because Fastboot was corrupted.so I followed the method I provided.
Hi Guys,
Hope you are all well!
I am having some issues with my hopefully-not-late Nexus 5 (hammerhead).
I originally wanted to flash AOSP 7.2.1 however during the process I ran into some troubles.
I flashed TWRP successfully, but TWRP does not start and reboots as it says it is not able to mount /data, etc... hence why the phone takes me to bootloader.
I have downloaded Minimal ADB and Fastboot from XDA, which works fine for fastboot, as it finds my device through "fastboot devices". However, adb does not recognise my Nexus 5, as it retrives an empty list of devices through "adb start-server" then "adb devices".
I have installed the latest drivers from the Google developers website, and I still get a yellow icon for both ADB drivers, i.e. Android ADB and Android Compounded ADB. Bootloader instead, works just fine as it recognises the devices when it is plugged in.
I am stuck trying to understand what I am doing wrong.
I had USB debuginng enabled before flashing TWRP and "lock state" is unlocked on recovery, as well as "secure boot" enabled.
I am using Windows 10.1 if it helps at all!
Thank you so much for your help in advance!
Quick update: I have noticed that when it boots into TWRP the device comes up for a couple of seconds, which means it is getting recognised but I cannot boot into TWRP. This is the error I get:

adb does not work in fastboot mode, only fastboot does. Is your data encrypted. Seems your /data partition is corrupted. You could use fastboot format data and see if it fixes it. Note that this will erase all data.
It may be best to use fastboot command to restore a stock rom, confirm everything is work, and start over.
You could also try using a different verizon of twrp.
Hi,
I am fairly new to flashing and rooting android devices. I managed to root my tablet a few months ago using the following sc00ter98 procedure:
Pad 11 (TB-J606F) Unlock! Magisk! RoooooT !!!
https://4pda.to/forum/index.php?showtopic=1014576&view=findpost&p=107199725 Translator from Russian: https://www.deepl.com/translator 😁🙃(y)
forum.xda-developers.com
But after that I noticed that my tablet no longer received Android updates, I wanted to manually update Android using the LMSA utility. I made a backup of my data before that so I could afford to lose everything. But once the process was finished my system won't boot anymore. In fact I am stuck on a menu at startup not knowing what to do.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
This is the only menu I have access to. I can change the "START" with volume buttons and there are :
Restart bootloader
Recovery Mode
Power off
Boot to FFBM
Boot to QMMI
But watherver I choose, this only reboot the tablet and then go back to this menu.
I would then very much need your know-how if you please!
Thans by advance,
Jiddu
Run this command:
fastboot set_active a
It worked very well !! Big Thanks !
What was the point after my "Rescue" action with LMSA ?
