JB system.img ? - LG Optimus L9 P760, P765, P768, P769

Where can i find it?

What system.img
I see you have a problem, you have been everywhere. Please say everything you did, your device model and if the bootloader is unlocked or not.
You can not flash the system partition in fastboot, it's to big.
CM 10.1 P769

I know i wrote everywhere but im sad ive lost my phone, probably it is hardbricked.
I was using mateo111's cyanogenmod, suddendly i received some FCs so i reboot my phone and it stuckd in lg logo, i try to reflash from SW Upgrade mode like always but this time it doesnt work, it stops at 50%. Now i realized that fastboot works and im looking for some ways to unbrick my phone this way. Probably my system.img is damaged cause now, when i try to turn on my phone it continues rebooting endingless. That's all

Is clockwork mod or twrp working, you can flash these in fastboot.

I tries flashing clockwork recovery but it always starts rebooting when i try to get in

Hold up I'm about to send you some stuff.
Have you tried holding vol(+)+home+power (release power when lg logo comes up) to boot into recovery?

Sure, always the same thing D:

Try erasing a couple of partitions.
Sorry but it sound like a hardware issue.
fastboot erase boot
fastboot erase recovery
And try to re flash the recovery (cwm or twrp)

Ive already done it, i erased those two partitions and reflashed from an old v20e backup, no way. I think system or hardware is seriously damaged, this continuos reboot is very strange (seems it doesnt have a system)

The really strange fact is that LG tool doesnt work, i used it almost 4 times with no problems, seems a driver problem

Na, it's not a driver problem.
CM 10.1 P769

Why has it aslways worked but this time no? (i tried also with the new 3.10 drivers)

I've seen the same thing happen to an galaxy s2, phone just kept rebooting, and vibrating non stop.
Sucks.
Sorry for your loss
CM 10.1 P769

So there is no way to restore system in fastboot?

It's too big to flash.

Try this, place your recovery.img (cwm or twrp) in the your folder and type
fastboot boot recovery.img
Note, change "recovery.img" to whatever your recovery is named.
This might give you some hope but I doubt it.
CM 10.1 P769

Here is the result, always the same, doesnt work

if i try to flash a new rom it gives me this: FAILED (remote: partition does not exist!)

What about trying to format the system. Yeah everything is pointing to hardware problems.

I wanted to know if it would give you an error that can't format, doesn't exist.
Okay last thing, and i'm done
you can use adb in recovery
try
adb shell
mount system
and then
cd /system
ls
to see if it will mount
Are you using twrp
I don't like cwm, I've had a couple of scares with cwm. I've had a problem with it not wanting to format or restore the data partition.
The only thing that got it working was umount data (with an adb shell). I couldn't unmount it the regular way.

"Sort of" bricked tf201 : Yup, I am dumb. Please help.

I created this thread because I have looked all over and have been unable to find someone with the exact same issue(s).
I said "sort of" in the title because twrp is working. Ok, so before everyone asks if I have nvflash, the answer is no. I did not have the right version of firmware, and did not try to install it originally. Since I was able to install roms, I figured I was fine...oops.
Twrp is not properly installing roms. More on that later. I am getting to the asus splash screen that says my device is unlocked, but it is stuck there.
My last working rom was the deodexed stock JB rom from craig gomez. I installed it with goo and when I installed that, I lost custom recovery and root, so I decided to go back to a more custom rom so Titanium backup would work. When I did that, I tried also tried again to make nvflash work. I got through the first step, it said it was successful, except I never got the little message in the upper left corner that I was supposed to get. I did not think it was a big deal because my prime would still boot like normal.
Then I installed twrp 2.3.1.0 and I have tried flashing previous restore images. I have tried installing the roms on my sdcard. I cannot get past the asus splash screen.
If I try installing a rom with the force md5 check enabled, it does detect an md5 and then quits.
If I try intalling a rom without the force md5 check, i get an error that says E:Unable to mount '/staging'
When I try installing a backup everything seems to work okay, but then I get the same error E:Unable to mount '/staging'
When I try to install roms through fastboot, I get the following errors:
archive does not contain 'android-info.txt'
archive does not contain 'android-product.txt'
error: update package has no android-info.txt or android-product.txt
When I try using adb, I do not see any devices.
I tried putting CWM on the prime to see if I could install from that instead, but it would not load after install.
I tried putting an older version of twrp on the prime, to see if that was the issue because I used to have an older version...I could not get that to load either...so I went back to this version.
Any ideas or suggestions would be awesome guys. I am stuck.
I even went to install the naked drivers again, and when I try to flash a different recovery, I get the <waiting for device> text that never goes away.
i'm sort of on the same boat. my prime just keeps booting into twrp recovery no matter what i tried. i'm still hoping to find a solution to this problem.

For me, I can let it try to boot normally, but I get stuck at the splash screen. This device is unlocked.
If I hold down the volume down button, I can go to fastboot, or RCK for recovery...but it does not work properly.

Same Here.. It all happened when i restored my files using titanium backup and when i rebooted im stuck at boot scrren
EDIT: Guys I did a prime fullwipe and flashed stock jb and now prime is restored to its original state..
""I also got some errors like md5 file could not be found and could not find the /staging""..but after the reboot it works perfect
EDIT 1: Now after the prime fullwipe and flashing stock jb i flashed twrp recovery and now it works perfect without a single error even the above mentioned errors were gone

That doesn't really help us. If possible, can you edit/delete your message so that the guys that might help do actually help? Don't want them to think this is done.
Can you clarify what the Prime fullwipe is and how you got there?
I do not know if it will help me.
I can't even do the wipe command from fastboot.
Just says <waiting for device>
I have tried the wipe command form the boot screen (the one with fastboot and RCK as options), that did not work properly either.

here is what i did. get into twrp recovery. flashed full prime wipe -> right after that flash the stock jb US version directly dled from Asus -> reboot then you will be stuck at the splash screen (that's a good news). Hold down power + volume down until your prime turns off and restart (keep holding those two keys) until the 3 icons appear then flash w/e rom you want in recovery. It's alive!
In twrp I do not see anything that says Full Prime Wipe. I see something that says wipe. Are those the same? I tried doing a wipe from this screen, but it did not work for me as expected.

no full wipe is a stand alone zip file you have to google and find dl it. put it in your prime then flash it
Thanks. That is what I needed to know.
I will see if I can make this work when I get back from work.

I am pretty sure I am F***ed.
I tried the prime full wipe. It worked the first time, I think. Then went to install a rom.
I had to do both through external SD in twrp because my adb is not working. Also, fastboot only works to install a recovery. The only version of any recovery I can make work is twrp 2.3.1.0
If I try an older version or CWM, it freezes where I try to go into recovery.
Unable to mount data error.
Unable to mount system error.
Same as before.
I tried using unbricker software I found, but since adb does not work properly, the software does not work properly.
I am going to see if I can work my charm and get them to take back my tablet at best buy for an infinity. I have read about other people pulling it off.
I think as we get closer to xmas my odds improve...UNLESS SOMEONE HAS ANOTHER IDEA??? I would love to try something else.
Eyeballer suggested a chat room channel thing, but most of the people are in europe and I would need to do it in the morning...I do not have time for that, but I may try it.

Download the zip:
http://goo.gl/hiFHB
Goto to Twrp recovery and install the zip..Since it supports microsd u can transfer the zip to microsd.
Goto TWRP -> INSTALL -> CHOOSE EXTERNAL SD -> INSTALL THE ZIP
It will completely wipe the internal storage and then download the official STOCK JB FROM ASUS SITE and follow the same steps to install. Now install the latest twrp recovery using fastboot

When I was doing the fullwipe the same errors happened to me.. But dont mind..I got errors like
1. No md5 file found
2. Mount error
3. Cannot find /staging
Just follow the above the steps ull get it right
did you even follow my step by step guide? you can move the stock rom from external SD to your internal SD in advance -> file manager.

Yeah, I should have said I tried that first. I also tried the stock rom from asus. When that didn't work, I tried the stock rom deodexed I found in goo.
There are a bunch of permission errors going on inside my prime. When I go into the mount area, it will not let me mount the data to move it. Or, when I try to copy it over I get a failed message.
Okay. I wiped it again, from twrp.
Then it let me move the file from the ext-sdcard to the sdcard.
I used the prime full wipe.
Then I tried to install the stock rom by transferring it in twrp file manager.
I got the file onto the sdcard, but when i tried to install, it said Failed.
That was it.
I even tried installing the ICS version I got from ASUS. Same thing.
Now, I am going to try to access via unbricker...don't know if it will work, but I am out of ideas.

us-tf201-jro03c-10.4.2.15-stock-deodexed.zip
That is the last rom I successfully used.
I used all sorts of different wipes. I was in twrp and noticed my pc installing the transformer adb driver. So I hopped into adb to see if it would see my device with that driver. (it did, but it wasn't before from the fastboot or adb commands with naked driver).
I tried sideloading the above rom from twrp. It worked.
Thought others might want to know.
I do not know if I can install other roms or not. I am a little scared to try just yet.

You will have the jelly bean bootloader now so as long as you stick to it you should be fine. The only other thing I would suggest is check you version of twrp, you should be running the jelly bean version of it also. And if I am not mistaken, you need to be on ics to use nvflash (although I haven't checked the op recently so I could be wrong) so definitely stay away from that unless you downgrade.

[HELP] LG L9 (P760) Is Stuck In CWM Recovery Boot Loop

So just an hour ago I got an OTA update for my LG L9 and of course installed it. It asked me to reboot and so I did, but it got stuck in the Clockworkmod recovery and when I try to reboot the phone it just boot loops in the recovery no matter what I do.
Tried wiping, formatting everything I possibly could, but still the same.
Also installed cm10.1.2, but it boots every time in the recovery after like 2-3 seconds after the LG logo appeared. The same was on the stock rom.
I was running the stock jb rom which was rooted and with cwm recovery installed.
Any ideas?

Normally, when in a Recovery Boot-Loop, you can boot into your ROM trying to Boot into Recovery.
That was my case and I think a lot of people's..
If that doesn't work, you could try this too:
Go to the Main Page of CWM Recovery
Select Reboot
Hold Volume - To cold Boot
You'll Boot into the ROM
After you do that.. open a new Terminal Window and write this:
Code:
$ su
$ echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0
Then reboot.. Your ROM should work like a charm!
No, still reboots into the cwm recovery every time. Tried both.
PS Should I have the stock rom when I do this cause right now I have CM10.1.2 installed

[Q] Other way to get to fastboot

Hello
Today I've tried to unlock my bootloader of LG Optimus L9 (P760) and install a custom ROM. I managed to unlock the bootloader after a few hours (Windows 8.1 sucks in this and do it on Windows 7 netbook is even more harder) and install the CWM. Then I wanted to install CM11, but the installation failed. I didn't realize that I need special version of CWM for this.
Well, I wanted to enter fastboot again a flash CWM again, but I couldn't boot, because the system was now erased. I couldn't install stock ROM, because phone wouldn't connect, so I grabbed older CM9 and succesfully installed it through CWM.
Problem is, that even from there, I can't flash CWM (flash_image recovery recovery.img in terminal doesn't work - shows error "error scanning partitions failed with error -1" - yet another problem no one can solve). And also, phone won't connect to my PC properly, because there is no LG Software mode in CM. Because of that, I don't see the device in adb and can't reboot it into fastboot. I tried to do it via wi-fi adb, which however only reboots phone and doesn't put it into fastboot mode.
What should I do? I can't install stock ROM, which would help (LG update tool doesn't recognize phone now and any driver I tried for "LGE U2 Device" didn't work... If it was available as a rar installer for CWM, everything would be OK again), I can't reboot it into fastmode, I can't flash CWM in any other way and I'm stuck with CM9, which I hate.
I don't understand why there is no other way, how to get to fastboot. Every other LG Optimus has a key shortcut (vol -, power), except L models and that sucks... I'm completly desperate.

Fastboot on these devices is a pain... Make sure you have installed the fastboot drivers twice.
Try flashing the recovery.img with Flashify (root) app from the play store.

Thank you for your answer I got into fastboot afterall by using app named "Rebooter (fast reboot)". It allows to reboot phone and make it go immidiately to fastboot. So great, now I could rewrite the CWM and install ROM.
Unfortunately other problems appeared. I'm using the right version of CWM for installing KitKat Android ROMs (and I've tried others), but I'm still unsuccesful in booting them. Instalation goes OK (ROM + gapps), but booting then is pain in the ***. I can wipe dalvik, cache, system... and return the phone to factory settings through CWM as I want, but every ROM gets stuck everytime on the boot.
At first, it takes at least 15 minutes, until LG logo disappears and the animation of booting starts. I left all ROMs to boot for an hour. But it seems I'm without a chance. Did anybode have the same problem as me?
BTW: This is my 6th smartphone into which I installed alternative ROM. I swear, that this is the hardest piece of crap for installing those, I have ever seen
Edit: I tried other kernels, also without success. It's strange, that I can install only CM9 and PACman ROMs. CM11, Miui, Mokee - no chance

If I remember correctly I think the cwm for cm11 has a bug that doesn't wipe dalviks. So flash ROM with the cwm for cm11 then restore the other recovery to wipe data. Or use something like rm -rf /data/* through terminal adb and reboot.
Make sure you mount the data partition first if you use adb and terminal.

[Q] soft brick question when flashing Cyanogenmod 11

After I attempted to install the CM 11 preview that just came out it seems as though I get stuck in a boot loop. I am able to get into the bootloader but not the recovery. The reason I think I am stuck in the boot loop is because I did not know you had to flash the boot.img that was inside the .zip file, and went ahead and flashed the .zip in my current recovery. I am just wondering if I could still fastboot flash the boot.img file without causing even more problems.
Yes, in the forum the ROM was posted (http://forum.xda-developers.com/xperia-z2-tablet/orig-development/z2-tabletdevelopment-cm11-android-4-4-t2809793) but I guess I didn't see that he said it was in the zip :silly:.
Nonetheless, I just don't want to hard brick the device so that is why I am asking. Thanks in advance for anyone that can help!

After I attempted to install the CM 11 preview that just came out it seems as though I get stuck in a boot loop. I am able to get into the bootloader but not the recovery. The reason I think I am stuck in the boot loop is because I did not know you had to flash the boot.img that was inside the .zip file, and went ahead and flashed the .zip in my current recovery. I am just wondering if I could still fastboot flash the boot.img file without causing even more problems.
Yes, in the forum the ROM was posted (http://forum.xda-developers.com/xperia-z2-tablet/orig-development/z2-tabletdevelopment-cm11-android-4-4-t2809793) but I guess I didn't see that he said it was in the zip :silly:.

Just to clarify first, do you have a 4G tablet or wifi version? And which one did you flash (castor or castor_windy)

Opps, meant to mention that. I have the castor_windy version (Wi-Fi) model and flashed the castor_windy zip. I also meant to mention that I have an unlocked bootloader with the CWM based recovery (found here: http://forum.xda-developers.com/showthread.php?t=2708194). I don't think this is as important but I do have the 16GB storage. I earlier said I could not get into that recovery that I have installed, but the violet light still goes on when I boot, but nothing else.

Ok no problem, Have you tried flashing CWM through fastboot, then reinstalling ROM through CWM?
If that can't be done, Can you flash this castor_windy version https://mega.co.nz/#!mJ5VTATR!Rb9pX0a4drAkVX53Mjf6_vZr8FqX0UzXcf1nSTzj_Fk
through fastboot, then immediately flash CWM to secure a recovery.
The link is the castor_windy ROM without having to flash a boot.img separately. Thats your safest solution instead of flashing boot.img
Thank you, just re-flashing the recovery from the thread I linked seemed to do the trick. Maybe I will try and flash Cyanogenmod later now that I got the stock ROM working again. At least I was smart enough to make a nandroid backup in CWM before hand though!
Again, thanks alot!

Good to hear!
Sent from my Xperia Z2 Tablet Wifi using XDA Premium 4 mobile app
Hi all,
bad day for me... It seems that I bricked my Z2 Tablet tonight.
At the beginning, I just wanted to install CM11.
My Z2 is a SGP512 Wifi only. So, regarding the page http://www.xperiablog.net/2014/07/12/cyanogenmod-11-nightly-builds-start-for-xperia-z2-tablet/ , it says : "There are currently nightly builds for the Wi-Fi variants (SGP511, SGP512) of the Xperia Z2 Tablet under codename “Castor Windy”" .
So I downloaded Castor Windy and put it in the tablet.
After that, I did had to install a recovery. I succeeded to install XZDualRecovery (http://forum.xda-developers.com/showthread.php?t=2794175). Once installled, I went into TWRP Recovery , started to wipe all. And next step, I began to install zip Castor Windy. At this time, TWRP tells me that Castor Windy is not for my tablet model. And I have to use Castor. Problem. I wiped all. So, I have to mount the Tablet systems and drives to put the new Castor zip downloaded. But I'm unable to mount. Nothing is mounted. I tried to use adb to connect while I was in TWRP but nothing worked. I wanted to use adb to send on one of partitions the new downloaded rom. I was unable to do that.
Finally, I shut down my tablet. I took the SD Card to put it into my PC and to put on it the downloaded Rom. And when I wanted to restart the Tablet, only the Sony Logo appears and I'm not anymore able to enter in recovery mode. ADB and Fastboot fail to detect my tablet.
I'm totally lost, and I fear that all is lost.
Please, help me, I just would like to enter recovery and flash Castor Rom.... :crying:
Thanks a lot by advance.
Tom.

You may have to LG UP and start over, also you can try one of the stock based roms.

Or at least fastboot mode ?

that's the important part, I don't really know how much the t-mobile models differ from the H930 ones
but there should be fastboot ? download mode ? "factory reset" functionality (via button dance botting into TWRP) ?

You might have done what I did which is flash twrp.img in recovery.. it won't go back to initial password screen. I did that and had the same issues.. I recently did it.. now it only restores backups which is how I got lineage or other rooms back.. after wiping the system partition, it also only flashes stock debloated room, but anything else I flash crash system partition.. I'm going to start over but with treble recovery in root process and just avoid messing with it..

Did you restores the recovery as well? I did that which is suspect source of the problem number 2.. even flashing magisk crash my system partition.. but not the magisk in the stock room, probably cause it's built in.. or any restores.. either way I'm going to start over.. not touching recovery after root & not backing up recovery partition to confirm a few things.. can you flash debloated rom after formatting system partition? Aroma gapps don't work for me but other gapps does.. I found out the hard way cause I didn't see any information on it in the threads.. I read it's a common issue with TWRP recovery on multiple devices..

I had that once when i tried to flash the aroma gapps for pie ?
that kinda ****ed up TWRP, a force reset (vol- + power) did the job for me, as all the reboot/shutdown options in TWRP didnt wanna work.

Exactly what happens to me try the aroma installer from gapps project and everything went down hill now I flashed the stock one they have.
How can I delete Google apps installed by gapps without making other Google apps crash
Did you not have a backup of your rom using twrp before you made the change? Isn't that the whole point of having twrp and a phone with SD card? Always backup your whole phone before making a change. It has saved my phone many times.

Yes I had a back up but it was twrp acting up by not being able to boot.
My phone was just booting back to twrp even when pressing power off some how by finally powering off the device (letting it discharge all the way) that was the only thing that fix it me twrp started working fine after that
My twrp has been acting funny/unpredictable. Or I am not doing something right. Mostly has to do with the restore function. I generally have two separate roms backed up in restore. But, lately, I will see only one listed. When I get back to the phone and check in my root manager, I will see them both listed. And then later, it (Rom) "might or might not" return to the restore function area.
But, lately it seems that when I restore the system, I can not open it up in the lock screen (does not recognize the pin). I have to turn the phone off, then use the vol down and power button to get back into twrp. Luckily, I have a couple of roms downloaded in the install section which then does let me flash and reboot, but I have to start new/over.
I don't know if reflashing twrp in recovery will help or not (have never done it).
I'm afraid one of these times I will some how get locked out or not be able to flash a good rom.

when it doesnt recognize your pin, go (in twrp file manager) to /data/system/ and delete the locksettings.db(-sh/-wal) files...
I think that was the path, you can google that too ^^
Thx, SGCMarkus, I did delete just the one db only file. It did away with the pin unlock code on reboot (but I did not do a restore, just a reboot back into my system), so I assume it will work. I will try it when I have time. I think that deletion has to be done everytime in twrp, because the line does reappear the next time I booted back into twrp?
Thx.
