Lg Optimus 4x HD Won't boot, System error, no mount - LG Optimus 4X HD

Ive had this phone for a month as a backup and I rooted it perfectly. Now for some reason it just stopped working. When I turn it on, it shows
Android System Recovery <3e>
Android System recovery utility
-Reboot system now
-apply update from external storage
-wipe data/factory reset
-wipe cache partition
-apply update from cache
-wipe nv partition
-toggle console VART Log
None of these work and I cant even factory reset.
On the start up, below it shows the Prompt
"Formatting /cache...

PLEASE HELP ME

How did you manage to get your phone in that state? But seriously, what did you do after rooting your phone that could cause this?
Bad thing you rooted your phone but didn't install CWM, you could recover a nandroid backup but, somethings weird here, "can't write NV partition" some people say restoring a nandroid backup fixed their issue.
Does your phone write this "E:can't write NV Partition." itself or did you choose option "Wipe NV partition" ?
As far as I know, NV partition contains IMEI etc., if the files are corrupted in there, theres nothing much you can do.
Try wiping cache partition, shouldn't be any danger in doing that, perhaps factory reset too but I don't think this'll fix your NV partition, you'll probably need to get your phone repaired and its rooted so your warranty is now void.
This problem is common among SGS3 & samsung users, but they usually can boot their phones, but can't access network.They r using some programs to re-flash their original files, they wouldn't work on our phones though.
I'm used to get such errors on my old phone. (not NV partition though cause I didn't touch it ever) These errors were usually due to using ext4 filesystem on kernels that didn't support ext4, so I guess your partitions are corrupt and your phone can't format them, did your phone sustain any physical damage lately?
Cache partition is supposed to be corrupted over time and formatted by system whenever that happens, It's easy to corrupt it but the problem with your phone is that it can't format it.
Try getting your cache partition working, perhaps you can still boot with your IMEI etc. corrupted and rescue your phone.
Try that 'KDZ firmware flash' method, most people use it to update their firmware versions but seen some people using it for unbricking their devices, however I didn't use anything other than LG pc suite so I don't know how you'd exactly do that.
It could also be that CAC file "/dev/block/platform/sdhci-tegra.3/by-name/CAC" corrupted, I don't know what that file does but it sure does have a role while formatting /cache, so firmware flashing may help with that
I'm not an expert, these are the only methods I have in my mind, good luck mate

there was none from the start. and I didnt do anything. I was just texting people.
Also do you have a skype? i need your help|
add EllisPlayist

I tried all those options, even factory reset, none of them worked

did you try to flash kdz file trough kdz flasher?

im new to all this, i need help manually. Skype pref. EllisPlayist. id love to fix my phone

Hi,
First of all what important is that you keep yourself cool. Read first and understand it then take any step.

Try the above given link if you can reboot into software update mode.
Otherwise you can try the instruction from @RuedasLocas in Post 7.
But as far I think LG Flash Tool should do the trick for you.
Hope you will be able to do it.
All the best.

It doesnt work

I tried them and none work. please help

factory reset "invalid argument" ?

This SGS had the original O2 ADJM1 firmware without the 3 button combo, which I fixed using the 3 button fix from another thread. SGS was working fine but I thought I'd give in and try a custom Rom.
Installed Darky's 6.0, worked great, but when I tried a factory reset from the settings menu, it kind of semi bricked, so I used Odin to install "GT-I9000_I9000XWJM8_I9000XXJM4_CODE-MODEM" with pit 512 to recover the SGS.
Problem is, Android Market will not download "download unsuccessful" pops up all the time.
The I installed GT-I9000_I9000XWJM9, hoping to fix the problem, while keeping recovery 2e, but Android market still does not download.
When I try the "wipe data/factory" reset using the 3 button combo, I get the following errors:
Appling Multi-csc

mps_dat value: KOR
copy_multi_carrier from : KOR
multicsc : can not access to /system/csc/KOR/system/

format_root_device: /dev/block/stl11Data wipe complete.
E:Can't mount /dev/block/stl11 (invalid argument)
E:Can't mount /dev/block/stl11 (invalid argument)
I'm guessing "E" is the internal SD card, so maybe there's a problem there
Also how do I fix this android market problem ?
I really need a pointer to installing a stock fully working Rom with recovery 2e, then I can move back to Darky's new 7.0 ROM.
Any help would be great.

Hi, i have exactly the same problem.
With the invalid argument problems on data/factory reset, and the download unsucessfull problem! i have reflashed 4times JM1 on my phone !!!
i give 25$ for someone who solve the problem !
The way I fixed this problem was in two steps.
I used the Kies registry hack (someone here has created a program (which I can't find a link to right now) for windows that fools Kies to recognize your SGS as requiring an official firmware update).
Once your SGS is back on your official carrier firmware, Android market will work again.
From there, I was able to do a proper factory reset, followed by installing Draky's 7 Rom, using the 3 button combo and update zip method......and till now it's all good.
My SGS went from being a useless paper weight, to a kick ass device.
Good luck.
*You mentioned JM1* you may not need to go back to that firmware, but whatever official carrier firmware that Kies updates your SGS to, should fix the market problem.
With the Internal SD Corrupted Fix, i have formated my internal SD and there is no invalid argument when i do a data/factory reset.
but i think this is another problem, i have tried anything.
The hang on installing/unistalling problem come when i add my Google Account on the Android Market.
After this, i can't install or unistall anything.. that show installing.... at the infinite.
(sry for my english)
i have created a new google account for re-downloading again applications on the market, but i'm really sad because i have bought a lot of with my other account! wtf...
can't someone have any ideas or can help me?
thanks!

Heeeellpppp
I have this Samsung Galaxy tab GT-p1000 whose applications are getting error message of "force close", I tried to delete all the installed applications, restored factory settings but It doesnt seem to uninstall all the applications, So I decided to
upgrade it from Gingerbread 2.3.6 to ICS after installing it I got an error message of "Encryption Unsuccessful", So tried resetting it, rebooting, wiping factory settings, wiping cache but nothing happened, I even removed the sdcard before rebooting it but still I got the same error message.
I got frustrated and made a stupid mistake, I formatted everything thru recovery mode, format /data, format /sdcard, format /system and all. Yes every possible format. Here comes the problem when I rebooted the system, I only got the "Galaxy Tab, Samsung" screen. I can't enter recovery mode anymore, I can still enter download mode but my pc won't recognize it, so Odin can't recognize it too. What should I do now? HEEEELPPPP pleassseeeee :crying:
If Odin can't recognise it, use a new PC.
Many have done so, even one last week.

Thanks for your Help.
same comment here as in there.
It is either the partition is screwed up or the NAND chip is bad.
If you did Odin with PIT file and repartition ticked, and didn't come back alive like the other forumer there, then your internal NAND chip is bad.
There are several threads dealing with how to use external SD only and on damaged internal SD.

Sir, it seems that this internal chip problem is a huge problem for gtab7 users.. is it better if someone make the tutorial on how to use the external sd to stickies so ppl can notice it? Thanks..

[Q] Problem with /cache in recovery

Hi there,
Just wanted to install a custom recovery image for the first time on this device and make a nandroid backup. Well, not everything went as expected
here's what I've done:
-unlocked the bootloader via htcdev.com [worked]
-fastboot erase cache [worked]
-installed TWRP [worked]
in TWRP I wanted to create a Backup and selected everything. However it gave me an error message that /cache couldn't be mounted (or something like that, can't remember exactly, but read on). So I tried it with CWM (again, first I erased cache with fastboot, then installed CWM) Well, these are the messages I get when I try to make a backup:
E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
then it backs up boot img, recovery, system and data, which works flawlessly. Then, the error messages continue:
No /sdcard/.android_secure found. Skipping backup of applications on external storage. [seems logical, as I don't have an external sdcard]
Backing up cache...
Can't mount /cache!
Is it possible that it can't mount /cache as I erased it via fastboot? Or what could've caused the issue, and how do I resolve it? Thanks in advance.
Doesn't matter, just ignore it
EDIT: To expand on the above, if you've not booted the phone up since flashing the recovery there is no cache to backup
Didn't think the soultion was that simple haha, but thanks

[Help] I'm having /cache mounting errors; how can it be fixed (no Windows)?

Hello!
I was going to clear the cache partition (ROM was acting strange) one night (night before New Year's 2017 of all the times) when these errors came up:
Code:
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
E: Can't mount /cache/recovery/last_install
E: Can't open /cache/recovery/last_install
Attempting to mount /cache fails with this error:
Code:
E: Error mounting cache!
I did find a thread showing this exact phenomenon: https://forum.xda-developers.com/crossdevice-dev/android-one-general/bricked-phone-cache-img-canvas-a1-t3307290
However, it's not helping me too much since the main solution there is using SP Flash Tool; it is (to my knowledge) a Windows-only tool, but I don't have a Windows install on any of my computers (all Linux units). Are there any alternate methods to resolving this issue?
EDIT: Originally intended to be a Q&A thread, but I forgot to check the box for it;oh well!
Same problem, not able to flash any ROM, clear any partition, or reboot.
As for SP flash tool, it hard bricked my friend's phone ( wiped everything but didn't download...
Searched many threads for this , but no solution..
Any help would be greatly appreciated.

A backup might be able to solve the issue. That won't work for me though since I had previously deleted mine due to a prior SD card failure.

TF701T partitions appear corrupted...HELP?

I stopped using my ASUS tablet a couple of years ago when internal memory started giving me trouble, but recently I started messing around with it again to see if I could get it working again. It appears that all partitions have no free space so that i cannot install a custom rom, fix anything, or really do anything. If I go to fastboot and try to force install a new recovery or new rom or anything it looks like it works but it really doesn't. if I try to boot, I just go in a boot loop.
I got twrp to boot(can't get it to install) and it tells me when I try to fix the partitions that they have 0 space?
Anyone have a tool or know the steps to delete and recreate ALL the partitions for the TF701t(K00C)? Any help would be appreciated.
I've tried twrp fix partitions, I've tried it's resizing as well. I've tried to install a stock rom, hoping it would rewrite them. nothing works.
Worse case is it possible to convince the tablet to just use an SD card as the internal storage and not use the emmc at all?
