[Q] Rooted my LG p880, and now it won't start

Hi!
I just rooted my brand new LG optimus 4x HD, and when I was going to install cyanogenmod on it, the phone stopped working. I pressed to restart in recovery and installing the rom, but when it was about to restart, it only says something like: unrecoverable boot loader, and something with kernel. I don't know what this means, but I hope there is a way to fix this, because the phone is brand new, and now I can't even start it.
Some suggestions?

Just flash original stock KDZ file with kdz flasher.

If you want to install CM, you do not need a rooted phone, but an unlocked bootloader.
Check the respective threads for details on how to unlock the phone and then flash CM.

ok, i'll try that in a couple of hours when I get home, Thanks everyone! I'll be back if there is another problem

in the lg pc suite that comes with the phone there is an option in "Device" for "emergency firmware recovery" this should be a relatively easy way to restore your phone if it allows you to do it without booting up otherwise use the method posted earlier. to get into the correct mode on the phone turn phone off, then whilst holding vol- plug in the usb (don't press power button) this should enter software upgrade mode.
after this you will lose root and if you unlocked your bootloader will relock it.
i used this http://forum.xda-developers.com/showthread.php?t=2256392 all in one tool to root and this http://forum.xda-developers.com/showpost.php?p=40918727&postcount=108 to unlock bootloader, you can use the all in one tool (from rooting) to install cwm after you have unlocked bootloader.
I hope this helps

I tried to root via the all-in-one toolbox, but I don't get how I am supposed to do... And after trying to do some things and factory resets, I'm unable to start my phone again. This time i'm stuck on bootscreen. And I can't seem to get to the S/W Upgrade screen again, i don't know why...
Is there something i can do with ADB sideload?

Open and reinsert your battery. It may help.
It helped me when couldn't get into s/w upgrade mode after flashing CyanogenMod RC2.

to get into S/W upgrade mode, remove battery, insert battery, hold the vol-, and plug in a usb attached to a computer (keep holding vol-).
hope this helps. also try a different pc usb port or a different cable (just to eliminate any variables)

Thank you so much for the video, it worked and now my phone is rooted and alive, now I just have to figure out how to flash a custom rom into it and the CMW recovery...

Good to see you ok. CWM needs unlocked bootloader not just root.

I don't know why didn't you understand my words but glad that you are running well now. For CWM or a custom rom, you need unlocked the bootloader not root.

I've managed to fix it now, I don't know how, but it worked thanks everyone for the help, running cm10.1 now

Is there anyway i can dowbload lg+ tag and quick memo? It isnt included in the rom :/

No, but I did a factory reset and flashed the rom, and then the stock apps werent included

Hi astr_x,
Do you have any example links for the respective threads you mention? I have tried adb and fastboot. I hold Volume down + plug into my computer and I get the Unrecoverable bootloader error that was mentioned above. In fact, I get this error even when I plug my phone to a normal plug (and not PC). Anyway, I connect my phone to my laptop (I always get the error mentioned) and when I type the relative adb+fastboot command in cmd (after installing all the relative drivers), I get "Error: Unknown device".
Any thoughts?

Cannot upgrade P7-L07 with EMUI 2.0

Hi,
a friend of mine has got in China a P7 with a strange EMUI 2.0 firmware (I always knew that P7 came with 2.3 since the first version). I wanted to upgrade it to the EMUI 3.0, then I downloaded the package from emui.com, I extracted the dload directory and copied to the internal memory (the same procedure I succesfully did with mine) but when I booted it holding Vol-, Vol + and Start button I just went into the stock recovery interface.
I though was a problem of the recovery, then I restarted with adb into bootloeader mode but the screen was all empty except for "fastboot mode" wrote at the bottom. When I tried to flash another recovery I got an error saying that flashing the recovery was not allowed.
Anyone knows what the problem is?
Thanks in advance

locked bootloader..

And also is resisting to any attempt to unlock: do not give Product ID so I cannot produce the unlocking code, neither are working all methods I found on the web. I may have to give up

maybe there is a firmware for your p7-L07 like there is for the p6-u06 where you can flash a so called unicom version and first downgrade and then upgrade/update..
and hopefully this downgrade unlocks the bootloader..
just my thoughts..

Thanks blueIBI, the problem is how to flash it, since the normal way do not work. After copying the dload directory on the phone memory, if I use the system menu to perform local upate or I reboot by pressing Vol+ Vol- Start I always end up in the recovery menu, the firmware gets never installed.
Will try harder.

Are you sure this is original P7 not some chinese crap looking like P7?

The phone belongs to a friend of mine. I own another P7 and they look exactly the same. It came in the original box with everything, so I have no doubt that it is original.
The fact that it has EMUI2.0 make me think that it was one of the first released to the market. The phone is working fine, just it is not upgrading on-line and I cannot find a way to upgrade it manually. I will try contacting Huawei support.

samsung s3 mini bring

Hello there,
I have the GT-I8190 model. I cant get it to boot from recovery (as the phone is totally bricked). I' ve tried the hard reset method (with the volume buttons etc.) and nothing happened. I have tried the Odin method - nothing there - as well as the flashtool method. The phone is unrooted with no unlocked bootloader.
I know there are a lot of posts refering to this problem, but I have really tried everything.
Any suggestions please?
Thanks a lot,
Maknis.

hi simo,i have root my phone from 2 last year and 1 day my phone he run restart per 5 minute,i try to make factory reset and on 50 % on factory the mobile he is restart again,after that i cant not open the bootloader .. i mean (up+home button+power button).

i think that's a hard-brick but this thread can help you : http://forum.xda-developers.com/showthread.php?t=2645482

I cannot upgrade any further

Hello,
I tried for a few days to upgrade my huawei to build B586 but I haven't been succesful. I unlocked my boot and tryied to upgrade trough brick method(but switching the img files to the b586 ones with huawei extractor). I have no option to update from local and the vol+,- and power buttons do not work. I get stuck at boot screen.
My curent build is B574. Do you have any sugestions how I can upgrade? or downgrade than upgrade? The update to 6.0 was done via update from local option,which i don;t have anymore.
Thank you in advance.

It works with me in similar situation, not sure if it work with you!
Downgrade B574> B300
and then...
Upgrade B300> B586 or B588

Hmmm... I had a similar problem. Coming from the RRevolution Custom Rom, when i tried flashing stock again i couldn't. The Power+Vol.Buttons method would give me bootloop. Even though the phone was booting, i followed the unbricking guide, flashing boot,recovery,system and cust (search it up, it's in the forums). After flashing everything and rebooting my phone, it went straight into the upgrade method (the one you get with the Power+Vol) and installed B586 just fine. No problems since and i am now using the B588, so it might work just the same with that one too. Hope this helps

Did you tried put B300 on the dload folder and then press 3 buttons?

From what I understood, you can't use the 3 button method, right? The phone will just boot... Try pressing all three and when you see the boot logo just release the power button and keep holding the other two. I've seen people getting over such problems by doing this. It probably sounds stupid but i would give it a shot... Also, try putting the upgrade.app file both on internal and external sd!

eRecovery is achived by volume up+power buttons right? When I do that It enters in update and says update failed
EDIT: removed the dload folder and succesfully wiped my phone, I will try to upgrade now(fingercrossed)
EDIT 2: I succesfully upgraded to b586. When I pressed the 3 buttons I got stuck at the same boot screen. When I pressed only volume up+ power button it workd.
So if any1 will have the same issue he should defenetly try this out. Big thanks for everyone who responded in this threat :good:

Redmi 9(lancelot) hard brick - HELP

Hi, I recently updated to MIUI 13. At first time it started normally but, when I tried to enter recovery mode, it frozen on bootloop. I don't understand what happened. I sent my phone to service center(2-3 times because I wanted to stay at MIUI 13. But it is bootlooped). Now I have this problem. I tried to install fastboot rom(MIUI 12) with auth bypass via SP flash tool. But there is an error:
STATUS EXT RAM EXCEPTION
IS THERE ANOTHER WAYS TO UNBRICK? OR SHOULD I GIVE IT TO SERVICE CENTER? ALSO, CAN YOU TELL ME HOW MUCH DOES IT'S REAL COST?(Because in first time I payed 10 dollars. Then 5 dollars in 2nd and 3rd times).
THANK YOU

Have you solved your issue if not reply me i also hard bricked by phone(redmi 9 prime(lancelot)) but able to solve yesterday. If you want I think I can help you on this.

Hi bro how are you? Well first step is to wait until your phone turns off. Then you need yo download ACT UNLOCK TOOL V2.O. After this, you need to install drivers via buttons above right corner of application. Then you need to hold two volume buttons and connect your phone(But before this you just need to press auth bypass button on the app). Then when sentences appeared, and it was written Auth Bypass OK, you need to press Flash button and locate to scatter file of your device in spflash tool(Your fastboot rom folder(unzipped)/images/MT6768Scatter.txt just something like that). Then choose firmware upgrade option and press download button. Wait some time and it will reboot to your system.
YOUR IMEI and DATA WILL BE ERASED!!!BE CAREFULL.
