[Q] Need help after erasing /system

Ok good people of XDA, need some help on this one. Did a lot of reading and trying but can not figure this out. I was wiping my phone through TWRP, and without looking wiped /system. Naturally my phone is now getting stuck in HTC spplash screen, I can still get into recovery, but then the when trying to mount USB strage under TWRP was getting unknown format, so like an idiot I formatted FAT32 and anything I put on there recovery does not see. What is the file format for the storage? I also can not RUU the via fastboot as I gives me the following
C:\\Android>fastboot flash boot boot_signed.img
sending 'boot' (6236 KB)... OKAY [ 1.885s]
writing 'boot'... INFOsignature checking...
FAILED (remote: signature verify fail)
finished. total time: 3.092s
C:\Android>fastboot flash system system.img
sending 'system' (1048572 KB)... FAILED (remote: data length is too large)
finished. total time: 0.006s
Probably because it cant read something. I did lock the boot-loader before doing it. Also, noticed the ADB commands are not working in the power off state either.
What do you guys think?

If I remember right, it's actually EXT4 and android uses FUSE to make it look like a FAT32 partition to a connected machine.
I would have suggested RUU, but it seems like that's not an option for you. Good luck with your phone, man.

If worst comes to worst just go to att and say it broke randomly, I don't think they can tell it's rooted if you messed it up that badly

Did you try just running the RUU ?

Ok, I beat it to death.... got it working. Somewhere in my trial and error process I ended up flashing to CWM recovery, which did nothing new for me, then I pushed TWRP again but the 2.1.8, was on 2.2 when the problem started.... all of the sudden ADB started working, not sure what happened on the newer version. I still did not see my SDcard, but I was able to push a version of cleanrom to the system partition. The install did not go, but the the process it formated the sdcard to the proper format.... or it restored some setting. I was then able to mount SD in TWRP and installed newest version of CleanRom.. All good now.... its all a learning process I guess

Encryption Unsuccessful - after Fastboot Flash of MZ600_HRI39

Okay so I seem to be bricked in some way. I've tried fastboot flash a couple times using OEM images "MZ600-HRI39" I have the MZ600 so that should be correct. Attached is my log of what I did, I eventually tried erasing each partition and rebooting to see if that changes anything, theoretically I thought I should be stuck since everything should be erased. However, I still get the Encryption Unsuccessful screen. Went back to recovery and tried wipe/user data and cache get BP fail with user data wipe and tried e: dev a few times before it stops. Then reboot and same. Any help or suggestions would be great. Thanks in advance.
P.S. I just want to get a stock IMG in so I can OTA to current; trying to keep stock so I can exchange at BB for newer tablet.
I just kept the log short only showing I erased each partition, but pretty much same result with flashes. All performed and got OKAY.

I think I got it. So you erased all the partitions... No problems when erasing data and cache, but the worst error you did was erasing "boot" and "recovery", so what I recommend you to do is:
1 - (easier way) download LordAIOTool for LINUX! (Windows is outdated...) and use Stock Install tool
2 - (harder way) follow this guide:
- Open cmd
- Plug your Xoom on fastboot
- go to Stock Files folder
- type fastboot flash (not sure if it's flash or install, anyway, I think it's flash ) boot boot.img (if downloaded from Motorola)
- type fastboot flash system system.img
- type fastboot continue
- Pray lol
Now all I wish to you is Good Luck

***I still get to Encryption Unsuccessful screen.....my thing is I don't even feel like it's flashing over anything, but not sure if that's possible. Almost like some write protection to the partitions.
Any other suggestions or does anyone need a paper weight?

not sure if this means anything either or gives a better ideal of the state of the device, but when I try wipes i get.."E:format_volume: make_extf4fs failed on /dev/block/platform/sdhci-tegra.3/by-name/cache" yet it states cache wipe complete. Then a bunch of failed to mount and can't open.

Try reflashing a custom recovery and with it try formating everything... Then try again everything from my other post again good luck

I've tried custom recovery, via fastboot flash recovery "recovery".img with no luck. It doesn't stick. Do you have any experience with RSD?

What do you mean with It doesn't stick?
Can you get into the recovery menu?
You could also do a oem lock and oem ulock again.
Then reflash everything again (boot, system, recovery if needed).

I go to flash with fastboot and when I try to access via power button, then volume down button I just back to OEM recovery. Was thinking if I try to rebuild system from bottom up that should clear everything out (bootloader, then IMG files). Was wondering if RSD would do that?

just noticed this in recovery when I perform wipe cache partition I get this message "E: format_volume: make_extf4fs failed on /dev/block/platform/sdhci-tegra.3/by-name/cache cache wipe complete".
So frustrated right now.....REALLY appreciate all the help!

Lord do you know how to enable USB debugging from fastboot, RSD, or OEM recovery? Found a forum mentioning a lock if OTA updates performed.

[Q] gn5 mysteriosly drops dead in middle of text message

Hi all,
I just got my brand new LG N5 (hammerhead d820(h) 32gb HHZ11K)... and after a week of using it i was sending a chat to a friend and the screen shoock a little then the whole machine froze. I had to reboot, but when I did, it froze when the colored balls appeared. After many attempts I decided to just reflash the whole thing with the hammerhead-kot49h factory image.
But when I do that, it never succeeds

fastboot flash system system.img (fails - device freezes on 'erasing...'))
fastboot flash userdata userdata.img (succeeds)
fastboot flash cache cache.img (fails - device freezes on 'erasing...')
I read somewhere that it is best to use the manufacturers tools, so I downloaded the LG Nexus Root Kit, but that was a mess.. still trying)
To me it seems like the internal memory just blew up!
so, my questions are:
Is this bricked?
Can i reformat and somehow mark bad section of memory off limits? like e2fsck/mkfs does?
Can i replace the internal memory myself somehow? (I live in Argentina, and to get this RMA'd, fixed and returned will take many many months and cost $$$ in import fees, assuming it doesn't get 'lost' in customs, like half my stuff)?
Any ideas?
It seems rather bizarre that a brand new N5 justs bricks itself for no reason... but, here I am.
Thanks for any advice

Bootloop! Unable to flash stock rom or lock bootloader (Help)

Hi. I can't get passed the google splash screen on a Nexus 5 D821 and could use some help.
Here are the facts:
* The owner of the device told me it bricked after an update.
* The Bootloader is unlocked. When i tried to lock i got the following message:
Code:
fastboot oem lock
...
OKAY [ 0.041s]
finished. total time: 0.041s
But it wasnt persistent. When given reboot comand the phone switched OFF instead. I turned it on to bootloader again and it was still unlocked.
* I tried flashing stock rom LRX22c manually after a failed attempt with the flash-all script. I got the following error for bootloader, radio, boot and recovery:
Code:
FAILED (remote: flash write failure)
* I tried erasing cache and flashing userdata but the after over 60 minutes waiting i came to the conclusion that i wasnt going anywhere and just rebooted the phone.
*The only thing im actually able to flash without an error message is system.img:
Code:
fastboot flash system ~/Downloads/hammerhead-lrx22c/image-hammerhead-lrx22c/system.img
target reported max download size of 1073741824 bytes

sending 'system' (981472 KB)...
OKAY [ 30.934s]
writing 'system'...
OKAY [ 62.705s]
finished. total time: 93.767s
* I tried booting TWRP, but i was unable to mount the file system (perhaps because i wasnt able to flash it. i used "fastboot boot twrp.img").
Are phones technically able to get to splash screen or bootloader with a damaged NAND or EEMC chip? Im starting to consider the possibility of a hardbrick. Why would i be able to write system.img if that was the case though? Any help is welcome
===============================================
alright so im pretty sure its a hard brick. The emmc is dead. its a shame :/ guess ill just try to sell it for parts. I would delete this thread because its pretty useless, but i have created my account a few days ago, and i ddont know how to.

You've only flashed the system img?
Do all the img's one by one. Recovery, boot, system, radio, userdata. Then fastboot reboot

I have tried all of the imgs in their respective order. they all failed. i got the error
Code:

. system.img was the only .img i was able to write, and i was wondering why. Also, when i try fastboot reboot the phone switches off. It doesnt reboot.

Phone bootlooping on Mi logo after updating firmware, unable to go into recovery

I was using official Lineage 14.1 on Lollipop bootloader with firmware libra_miui_v8120_fw_patch, then today stupidly decided to update firmware with libra-firmware_miui9-7.8.21_7.0.zip which is probably for Nougat bootloader. Now I am unable to go into recovery and also when trying to flash recovery through fastboot I end up with this:
Code:
fastboot flash recovery twrp.img
target reported max download size of 536870912 bytes
sending 'recovery' (40704 KB)...
OKAY [ 1.343s]
writing 'recovery'...
FAILED (remote: Partition flashing is not allowed)
finished. total time: 1.362s
So can't even flash recovery. Fastboot oem unlock ends up with this:
Code:
FAILED (remote: Token verification failed, reboot the device)
finished. total time: 0.031s
tried also flashing logo.bin into bk2 just to verify if partition is logged and end up with same issue as with recovery, apparently bootloader locked:
Code:
fastboot flash bk2 logo.bin

sending 'bk2' (9591 KB)...
OKAY [ 0.329s]

Is there any way to flash through fastboot just firmware and get back to where I was before screwed update so I don't need to go through flashing fastboot MIUI ROM, losing all my data in phone and setting up phone from scratch? At least in worst case I hope that's an option and it would work just to flash old libra_images_6.1.7_20151221.0000.11_5.1_cn_b09dac70a0, then do oem unlock flash TWRP and the go to lineage, as i did without official unlocking before, but I would rather avoid this since I have still some data not backed up in the phone (luckily i backed up photos just before flashing).
EDIT: Or is there a way to at least back up my data out of phone through fastboot?
EDIT 2: according google results not possible to do backup through fastboot and according fastboot oem device-info it's locked bootloader, so back to square one, losing files, grr and start from scratch

Steps 2 to 9. It should work.
Might be another way to save your data but I didn't found one. Maybe your pc will se your folders in fastboot so you can save the data.

You can also try to unlock the bootloader the official way, then install TWRP and flash a lollipop firmware zip with the lollipop bootloader and try to boot your ROM that way. The zip floats around in one of the ROM threads.

yeah, I did that as usual when unlocking unofficially, but there is no way to see your data, though in miflash it says in bottom "save user data" but nothing was saved, I looked through all phone, can't find it anywhere

OK, I noticed another issue, my available space significantly shrank. I guess it's because during fastboot oem edl flashing fastboot MIUI dev ROM through miflash I left "keep user data" checked instead erase, hoping I can recover them somehow.
Now Settings/Storage shows me that my System takes 21GB out of all 29GB, which is nonsense, since it's pretty much fresh system with few apps and little data used.
So my question is, can I somewhere find my original user data taking all this space and manage them? Or is user data partition (internal storage) somehow corrupted and I should just format it and this should hopefully fix problem with lack of free space (although Settings are showing System is taking all the 21GB)? In Mixplorer Internal storage is showing capacity 7.75GB and Root 1.82GB, so I would think it's corrupted internal storage which should be formatted, although best would be if original data would be somewhere hidden and I could just delete them manually.
EDIT: SOLVED - go to TWRP / Wipe / select Data / Repair button / Resize / and partition was properly resized from 7900MB back to 26136MB without loss of current data, of course original data from before are gone, but I am already over it.
