[Q] lg p760 not working, & hardreset wont work - LG Optimus L9 P760, P765, P768, P769

I hawe problem with my P760, I'we flashed v20c version, rooted it, then stuck, now I cant flash any firmware any more, and i cant do hardreset, when I try to do hard reset with volume down + home + power i got an cwm menu. I try to install rom from cwm but with this no luck too. Maybe someone can suggest me something else?

Just use KDZ online method if nothing works. It will unbrick your phone for sure.

This is good news that you can go in CWM mode. Fine.
1) Before you started flashing I am sure you took nandroid (cwm) backup in CWM as a habit. Right? Just wipe data and cache partition, wipe dalvik cache and restore the backup. You should be back on your previous rom.
2) If this does not work. As you were stuck after V20C, download any working V20C nandroid (cwm) backup from this post and restore it.
3) If this also does not work, try recovering firmware with PC Suite or
4) flash fresh matching rom with offline fix method.

[Q] Help I bricked my Galaxy S2

Hello XDAérs,
I unfortunately bricked my phone. I started with downloading ODIN and CF-Root-SGS2_XW_CLK_KF3-v4.0-CWM4. I was able to get into the download mode and open the .tar. This was succesfull, I got to see my homescreen after the reboot. After that I made a backup using CWM.
And this is where I made the mistake. I opened CWM and opened cm_galaxys2_full-65 by using Flash an update. The device booted and started to install this and afterwards got stuck at the yellow warning sign!
I was hoping to fix this by going to the download mode and using ODIN again but this didn't help.
How can I fix this?
#UPDATE: Can i fix this anyway in the ClockworkMod Recovery (Sound up + Home + Power ) ?
Greets
restore your backup
hold up instead of down when you start your phone..
down=download mode
up=recovery...
when restore is not helping try restore wipe... all data will be lost..
I accidently pressed backup instead of restore... -.-. But I chose the oldest backup afterwards. This didn't work and also a restore swipe didn't help.
Before you gave me this advice I had tried to install the .tar file threw ODIN again, might this have made the back-up and restore impossible?

No it doesn`t matter.
If you want to install CM7 go back to recovery Volume up + Power
Wipe data/factory reset
Wipe cache
Wipe dalvik cache
Format System in mounts and storage
Flash the rom and google apps
Done
Hey,
I followed your instructions but when installing the .zip file the installation gets aborted.
Should I try apply /sdcard/update.zip?
thanks in advance

NO, turn the phone off and go back to recovery and try again.
If that doesn`t work turn the phone off, go into download mode (volume down and power) than yes (power up) and flash a stock rom for your country with Odin.

Or if you have a working backup as i read in yout thread restore the backup
use recovery wipe everything data, cache and dalvik and see what happens...if that does not work if you can get into download mode flash litening rom with odin and you should be fine..
once you got litening rom on then check what rom you want to put or just go back to stock from the region you from
Hey, I installed the stock rom and did it all over again, and now it works! Thanks for your help

P760 Bootloop problem

I've unlocked bootloader, tried to flash new rom and now i got stuck at rom's logo. I just can wait forever and nothing happenes.
Tried to wipe, and even format everything (data/cache/system) and nothing.
Tried CM10.1 i a zip, ExperiencedStock as a backup, and even my own backup i've made before.
Everytime i got stuck at rom's logo.
I dont know how to put my phone in SW Update mode since i got CWM, and every time CWM starts and i cant flash it with LG support tool because the program doesnt see my phone.
Did anyone had this problem?
Maybe stock Recovery.img would help? Anyone could give me it? I can try to flash it again with fastboot mode.
Or any other sugesstions?

Try hard/factory reset ; turn off your phone , hold vol- & home ,press and hold power for couple of seconds
With vol-,home & power it also boots to CWM :/
Have you trying to restore stock rom via Cwm? You can download fresh one from our forum.
Go to advanced and clear dalvik cache it might help
Wysyłane z mojego LG-P760 za pomocą Tapatalk 2
Yes, tried fresh CWM backups also.
But finally i solved this problem
Dont know why, but when i formatted internal sd, rom booted with no problems.
Firtstly i didnt want to format internal sd because there was my backup in case something goes wrong.
But it went wrong, so i had nothing to loose
So if anybody will have this problem then format everything (cache/data/system/internal_sd, wipe Dalvik), then restore backup or install zip from sd_ext.
ExperiencedStockFinal booted ok, backup made on sd_ext also.
Will now try to install CM10.1, and maybe i'll investigate why i have this bootloop bug on my phone.

Serious problem help!!!!!

I have a serious problem in my rooted S3. After flashing a problematic rom, i was forced to reset nandroid backup(i had already flashed the rom which i take the backup) Restore was successful, but suddenly I had issues with network("not registered on network") After flashing the latest modems from this video everything was fixed.
However when i flash a new rom from recovery, the screen always freezes on samsung logo. The only solution is to reset each time the latest that nandroid I had. In addition today, i have not acess in recovery(philz). What you suggest me to do? Sorry for my enlgish and thanks in advance for the people who answer.

I simply suggest you to flash some custom ROM,flash some patched modem and patshed kernel and hope everything will be fine.

Things are not so simple. I cannot have access in custom recovery menu. As a result it is impossible to flash a new rom,modem,kernel or restore a nandroid backup...
Download mod is working?
Flash stock rom for your region, through odin

have you tried reinstalling the newest CWM of TWRP threw downloader mode and then trying to boot into it.
i would try that before i restore to stock, i prefer TWRP but it is more of a personal choice.

So i flash custom recovery via odin and then i unroot my device. right?
If you want to return your device to stock just grab the correct carrier OTA file for your X and flash it via Odin and you will be 100% completely stock. No root stock recovery and stock Rom

Yes install PhilZ recovery it as a option to use file Aroma to backup and move files look here >> http://forum.xda-developers.com/showthread.php?t=2201860 << especially the "Special Features Guide" also it as custom backup options.

Be careful because PhilZ as a option to do a normal wipe factory reset but also a option to install a new rom which formats all the necessary files to do that including your system (rom). This can leave you without a rom to boot into if you don't know how to use it propably,I would just recommend just flashing back to stock with Odin (and don't forget to factory reset after using Odin.

If you have tried flashing stock (and you have flashed everything correctly and wiped correctly) and you are still stuck in bootloop the only option I can see is to try the rescue firmware in the stickies forum.
Be very careful and follow instructions carefuly as it containes a pit file,if this failes then I would suggest service repair.

Tried to wipe again and booted up. It just took longer than normal (5mins) and then it booted up as normally. Thank you very much !
Now, if I want to flash Cyanogenmod again (Not Installer !), I just have to root and then flash Cyanogen Mod, right ?

Yep I agree don't use installer seen alot of problems with it... If you just want to install Cyanogen Mod (or any custom rom) with custom recovery then you do not need to root (only root if you want to backup or access anything from system), all custom roms come with root included. Just use a custom recovery wipe then flash your rom (factory reset if it bootloops) done.

HI tall man, Same here Ive stuck in Samsung galaxy Siii GT-I9300 Logo only, and i cant also go to recovery mode, which i dont know. but i can go to download mode. this happen after my phone restart automatically. verison 4.4.2 kitkat by archi, Thanks

[Q] root then flashed STUCK IN BOOTUP: gummy, personal backup, CM12 +then kitkat -

I rooted for the first time over the weekend. Thought I had a problem with international unlock sim (and wasn't too happy about GPS and mobile data widget) - so it was a good excuse to root... I have a Sprint Note 3 with lollipop (5.0 that I got OTA)
Anyway did the root via CWM via these steps: http://galaxynote3root.com/galaxy-note-3-root/how-to-root-galaxy-note-3/ I was able to install titanium backup and backuped app and my personal stock sprint.
There after I flashed 1. gummy rom 2. restored my personal sprint rom backup 3. CM12 and 4. latest Kitkat Killer version.
On all these flashes I got hung on the bootup logo. I reflashed after waiting 10 minutes and the same thing happens (some say it would work on the second flash...but alas!)
From what I gather it's because I am going from 5.0 to 4.4 roms ? Is that true ? If so how can I downgrade to 4.4.4 ROMs ? OR is it easier I find a 5.0 rom I like and flash that. Interestingly though my personal backup restore didn't work either to 5.0
[Currently I don't have a phone and desperate to solve this.]
PS: I didn't wipe data or factory reset between the various flashes - could that be a problem or is THE problem ?
(It all started because I thought I lost international sim unlock that i got via SUU app...it seems I hadn't)
Got to factory reset!
If the same version of rom wiping cache might work.
I factory reset/wipe date via CWM and there after recovered my original data again via CWM.
And now its back to original Sprint bootup - BUT gets stuck at the Sprint logo ?
I try a hard reset via volume up, home button and power - and it just does a bootup - so cannot do a new factory reset ?
have I lost my phone ? should I try ODIN ? what are my options ? (and how did I screw up? )

Boot into recovery wipe every thing.
Flash your rom again.
&/or
Oden stock rom, try again.
Didn't follow instructions ; -)
1. when you say 'flash your rom' you mean my backup of sprint ? so do a restore of the original sprint that I backed up after root ?
2. where can I get a stable stock rom ? I assume I have to use stock 5.0 ? as it's not easy to downgrade to 4.4.4 as I got 5.0 OTA - right ?
PS: what instructions - i followed everything to a tee...
thank you @rbeavers

thanks.....but still a little confused because I was able to flash to MOAR 4.4 ROM but when I tried 4-5 other ROMs people said I couldn't flash down to 4.4 from 5.0 stock sprint. But I did (without doing anything different!)
