Sometimes I completely wipe my device before puting a rom on it, when I got my Gnex obviously because it had no removable sd card I couldnt remove it and format it.
I used this command yesterday to wipe my rooted N4 and it wont boot, I've flashed a stock image to get it up and running again and for testing purposes tried it again but with a different rooted rom, same outcome.
1) Does anyone know why this would be?
2) Is there a better way to completely wipe my device without causing this problem
Thanks in advance
on fastboot erase userdata
Hello.
I think I got into a similar problem as you did.
I wanted to write JOP40D using the google factory images on my Nexus 4, and in the process I also used a combination of fastboot -w as well as fastboot erase userdata. Now my phone won't boot up completely.
I wanted to ask you if/how you managed to recover to stock...
I personally tried using google's stock factory images for Nexus 4 (from developers.google.com), without success.
Thanks in advance.
Re: on fastboot erase userdata
FYI, Nexus 4 Toolkit did it for me.
1) The problem is the google factory image script does not reformat userdata && cache. These stay damaged from the initial fastboot erase operation done within the same script sequence. The Toolkit does 'reformat' them.
Not sure why this happens, may be from a bad erase that does not trigger reformatting, but it probably has to do with the version of fastboot you run on your PC versus the fastboot backend phone daemon. I posted online about this and hope to get some answers.
2) There must be a way to trigger this reformatting of userdata && cache...

1) Doing this on my Atrix 2 also causes a bootloop. I'm assuming it's because it is completely erasing the data partition instead of formatting it.
2) Try using fastboot format userdata (this works for me), or use the toolkit/a custom recovery to do your wiping.

Yes, there is a way to format partitions. The most recent version of fastboot supports this command.
Code:
fastboot format <partition>
So it works like this:
Code:
#format userdata
fastboot format userdata
#format cache
fastboot format cache

Thanks! I was stuck at the endless boot logo after trying to restore with the factory image via fastboot. This got me back to normal booting.
Ok so I updated my SDk last night and typed (without quotes) "fastboot erase userdata" it gave me a message saying DID YOU MEAN FASTBOOT FORMAT USERDATA" then it completed the action however my phone still didnt boot.
Sorry for my ADB noobness but just to clarify...
I used to type exactly as this "fastboot erase userdata"
And now I have to type this
"fastboot format userdata" which should fix the issue, Erase all userdata (media, pictures etc) and boot the device
Thanks again chaps

^^^ This, I have been going crazy trying to figure out the issue with the hanging boot. The format makes it boot everytime.
The problems are being caused when fastboot erase is used to delete the contents of the partition.
FASTBOOT ERASE IS NOT NEEDED ON THE NEXUS 4 (only the Nexus 7 uses fastboot erase to wipe the partitions before flashing).
If flashing manually just use the google script supplied with the stock image to flash correctly (from the jop40d build. If flashing jop40c then use the correct image names for that):
fastboot flash bootloader bootloader-mako-makoz10l.img
fastboot reboot-bootloader
ping -n 5 127.0.0.1 >nul
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.33.img
fastboot reboot-bootloader
ping -n 5 127.0.0.1 >nul
fastboot -w update image-occam-jop40d.zip
Or use the Nexus 4 Toolkit to do it all automatically and properly

Hi all,
My n10 is bootlooping and I tried to flash a factory image from ADB but it fails with the error that there is no space left. Is it possible to erase the SD card through ADB? Thanks!

Yes
fastboot erase data
But when flashing new software its best to
fastboot erase system -w
Side note, I have seen this issue fixed often just by updating fastboot and adb binaries on pc
Hello all,
I left a similar post in a couple other threads, and thought maybe someone here might have some insight into my problem.
Been running AICP rom (no custom kernel except the one that comes with AICP) with f2fs on /data and /cache for several months on 16GB grouper. About a month or so ago, the wife installed a game that wouldn't run on this hardware (King's Paradise Bay), and I uninstalled it. It left a file in /data/data/....etc that couldn't stat in TWRP, so no nandroid backups since then. I figured I'd just backup user data with TiBkp and wipe with fresh install of latest AICP when time permitted.
The other night I noticed the N7 was boot looping, getting to the stage where the boot animation dims. The boot anim would hang and after several seconds the Google unlock splash screen would come up and the N7 would try to boot again.
I can get into TWRP and bootloader with no problem. However, when TWRP comes up, the log shows the red entries for 2 files that can't stat, which has been this way since that game was uninstalled. I cannot seem to wipe *any* partition, and when I attempt to format or wipe userdata in TWRP, the N7 spontaneously reboots. Manually attempting to wipe/format/etc. via FastBoot doesn't work, with error message showing after trying to flash bootloader. Also, I can't change /data or /cache back to ext4. I am able to successfully read, write, and delete files on the N7 via computer USB MTP connection.
If the N7's flash memory has somehow become corrupted, is there a way to completely erase/format/whatever so that this wonderful device can become usable again? Any help would be greatly appreciated.
Thanks in advance.
Hello,
don't flash Bootloader via Fastboot. You should do this commands:
Code:
fastboot erase cache
fastboot erase userdata
fastboot erase system
fastboot erase boot

Yes, I have attempted all these commands, followed by flashing with either fastboot or TWRP with no success. Fastboot reports success, but partitions are not erased.
I have the same problem. The Nexus Root Toolkit can not flashign. It succeeds only boot TWRP. In TWRP computer sees the files from the tablet.I could not rename and delete. Wipe the TWRP and stock recovery displays the status OK, and the files are deleted. Fastboot shows that uploads, but all files remain unchanged.
Hello, I wanted clean flash stock rom on my Galaxy S5 G901F so I did that using Nand Erase All and I did it 2 - 3 times to try different Regions. After the flash was done I was getting "device memory error: the data partition has been corrupted. You need to reset your device to factory defaults. This will erase all your data." After I pressed the button everything was erased and it was working fine. Did I do any harm to my device ?

If it was just a partition corruption you should be fine. This is usually just a problem in the partition tables that the phone can't fix without wiping everything and rebuilding all the partitions on the device.
After you run a NAND Erase All, it is usually a good idea to import a PIT using Odin so it can rebuild the partitions correctly.
Hi i need to do a fastboot to do the command fastboot erase modemst1 bit my botloader is locked I think so I can not do this right? So please how to unlock the bartender without wipe data? I already try but none work

You can't unlock your bootloader without wiping the /data partition. That would be a huge security flaw.
Edit: Besides, why are you trying to wipe your modem? That is a terrible idea.
