General :: LG Optimus P500 System Recovery
Mar 30, 2012
Im really stuck, my phone is rooted, is deleted something that i didn't know was important(with titanium backup pro) and it failed everytime to restore, so i tried to reset my phone to default setting.
But guess what, my phone boot but stop at "the application settings(process com.android.settings) has stopped unexpectedly. Force close )
I got a back up of the original rom that i made with clockworkmod so i would like to restore it. But i cannot boot in systeme recory mode
i tried:
vol up/down + home + power = no result
vol up/down + back + power = yellow and it says "emergency mode!! but nothing happen"

I recently did this and now I'm unable to run custom ROMs on my Optimus One:
>Downgraded baseband (so as to install ICS ROM by DaxElectro
>Then installed the above mentioned ROM and I loved it!!!
>But later found some limitations of it. (The SIM that I was using didn't let me access internet over this ROM. Other SIMs worked fine). I thought of telling to the developer about it.
>So I installed original, official Gingerbread 2.3.3 firmware V20c (India) again, through the backup created using Clockworkmod Recovery and also upgraded the baseband.
Later I wanted to show my friends the ICS ROM as they all wanted to see it. But before flashing that ROM, I wanted to try mik_os's Cyanogenmod on my phone and test it.
>I installed that but this ROM gave a boot loop error (of course I had again downgraded the baseband) I thought it is buggy so I removed and flashed DaxElectro's ICS ROM again, thought it would work fine as before.
But, now even this ROM is giving the same error!!! I'm very upset as I'm not able use it now!
How to fix this???
Yes but my official firmware is working fine and I posted this using that only.

I'm trying to porting cyanogenmod, but I have a problem unlocking the bootloader for recovery. Let me explain what I've done so far.
Root Phone via framaroot
Extracts recovery.img boot.img via adb
Code:
sudo adb start-server
adb shell
su
dd if=/dev/block/mmcblk0p9 of=/sdcard/boot.img
dd if=/dev/block/mmcblk0p17 of=/sdcard/recovery.img
exit
exit
adb pull /sdcard/booty.img
adb pull /sdcard/recovery.img
Initialized the project via mkvendor.sh
Code:
mkdir ~/android/system/vendor/LGE/vee7e
mkdir ~/android/system/device/LGE/vee7e
~/android/system/build/tools/device/mkvendor.sh LGE vee7e ~/boot.img
cd ~/android/system/
. build/envsetup.sh
make -j4 revoveryimage
make -j4 recoveryzip
I now have the CWM Recovery, and I inserted in my phone
Code:
cd ~/android/system/out/target/product/vee7e/
adb push recovery.img /sdcard/recovery-cwm.img
adb shell
su
dd if=/sdcard/recovery-cwm.img of=/dev/block/mmcblk0p17
Reboot the phone for enter in recovery mode (hold volume up + home button), and I had this surprise
Code:
[4380] -------------------------------------------------------------------
[4380]
[4380] Secure booting Error!
[4390] Cause: boot certification verify
[4390]
[4390] -------------------------------------------------------------------
In the attached you will find my recovery and the error message.

After update my Optimus L3 got in a "No service" situation. The strange part is that i have signal and im able to access the internet using mobile network (wifi off). After a long research i fugered out that my IMEI was 0 (zero). I finded a lot of solutions to this problem but none of then was compatible with my device or brand.
Its possible to perform this in an Optimus L3? How can i access the Port Settings?
(ultimate solution for several LG devices) Restoring IMEI
1.Connect phone by USB
2.Activate USB debug mode
3.Enter 3845#*920# in dialer if that doesn’t work try 3845#*925#
4.Select Port Settings -> Select CP Image Download
5.A new device should appear at let it install
6.Open Tutty and select serial protocol. Click on open
7.Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)
8.Type at%imei, it should display a dummy IMEI
9.Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x where x,x,x... is your orginal IMEI number (found under the battery of your phone). It should response IMEI WRITE OK
10.Reboot phone

So I wanted to install a custom ROM to my P350 today and it seems I can't get into recovery mode. When I try to get into recovery, it shows the LG screen, shows that recovery mode screen, freezes on that screen, reboots and EVERYTHING ON MY PHONE GETS RESET,
I've tried 3 different ways to get into recovery, all of them have this result. It is very annoying that each time I try to get into recovery the phone gets a factory reset. How can I get into recovery?

I cannot get into my recovery. Alright so i bricked my AT&T lg optimus g after trying to delete some bloatware after rooting my phone. I unbricked it by using LGNPST and got stock android 4.1.2. My software version is E97020j. The phone works perfectly fine but i cant get into recovery and i want to flash some custom roms. I can root my phone perfectly fine. The only way ive seen that unlocks the bootloader of the optimus g is a program called project freegee. When i try it, it tries to reboot into my recovery and bricks my phone. Then i have to use LGNPST again.
Ive used apps like clockwork mod manager and it says i already have TWRP and Clockworkmod recovery installed but it wont reboot into any of them. It just comes up to a black screen and says "Secure boot error, cause: boot certification verify." Ive tried getting into recovery using adb on my computer and using the old hold power button and up volume button method but nothing has worked. I cant find online how to get my old stock recovery image or how to fix the red triangle and i dont know how to uninstall TWRP and Clockworkmod. The methods for other phones doesnt work on mine.

I accidentally flashed the wrong recovery onto my LG Optimus V. The phone is stuck in a boot loop and I am unable to make a selection in recovery. How can I flash the correct version of clockwork mod without doing it through the phone?

I recently rooted my LG Optimus L3-8C (E400) running stock rom and version 2.3.6 Gingerbread (yuck) and I followed all the instructions from this video:
in order to flash the CM9 ROM. Problem is I can NOT reboot into recovery no matter what I do it seems. When I try tp reflash the CWM recovery it tells me "successfully installed!" then when I press 'reboot into recovery" it gets stuck on the LG logo for so long I often have to hold the power button to go back to my device. I even download "recovery flasher utility" found here [URL]....but, whenever I run the app it tells me "no recovery.img" found onexternal SDCARD even though I placed it there! I tried to fastboot but whenever I run CMD it tells me " 'fastboot is not recognized."

I'm having trouble booting my LG Optimus G into recovery mode. I've rooted the phone and installed ClockworkMod recovery. When I try to boot into recovery, either from the ROMmanager app or by holding Volume Up and Power, it comes up with the LG logo and gives this error: Secure Booting Error! Cause: boot certification verify. It just stays like that until I press and hold the power button again until the phone shuts off entirely. Then I'm able to boot into the stock operating system and the phone works fine, but I can never get it to boot into recovery.
The error I mentioned above seems to be a well documented error on the internet, but it seems like other people that are having the trouble are completely bricking their phones. Mine is able to come out of it. All the solutions I'm finding pertain to a phone that's completely bricked and involve taking the phone back to stock. My phone works fine with the stock ROM, but I'd like to play with some custom ROM's.

I'm trying to root my T-Mobile L90 as per this guide: [URL]
But T-Mobile has locked out Recovery Mode so that button combinations and "adb reboot recovery" do not work.
Any way that I can remove this restriction or force recovery mode?

I had done several things before (rooting, installing cwm recovery through rom manager, etc) until my phone got bricked, and tried a lot of things until i have flashed Cyanogenmod, and it woks just fine (and its cool), but I have changed it back to original stock firmware using KDZ flasher. Now, I tried to boot my phone in recovery mode (by holding volume down+back+power button) and CWM recovery is booted. I want to get rid of it and restore back my original recovery, because, i suppose, it was the reason why my phone was bricked before (i wiped and formatted the system and updated the firmware using fOTA, and the result was a CWM bootloop)

So I was having a problem with my Optimus V (Virginmobile) and I couldn't send or receive texts. I did a factory restart thinking it would work but then found myself at the recovery menu. When I try to flash xionia_cwma_12518.6.zip it says E:cant find update script. When I try and flash CM7.2RC1_VM670-BobZhome-052012 it installs and when I reboot i get taken back to the recovery menu.
In short; My Virgin Mobile Optimus V is stuck in a recovery loop that I am unable to get out of due to an error while trying to flash ROMs/ Custom Recovery.
The error reads at the end of all attempts: E: Can't find update script.

Phone: UK Galaxy S Issue: Recovery boot error message in red writing
Multicsc : can not access to / system/csc/VOD/system/
Background: I have been trying to root my phone from information found in a youtube video. All went well and the little ninja bloke with the sniper rifle was in the app list. Tried installing busybox and was told that the phone was not rooted�..
I think I ran the root application again and at some point I started getting this error message when in recovery. I have since run the one click root method to unroot the phone and the little nija dude is no longer there. Since I rooted the phone it will no longer connect to my wireless network, it finds the network and attempts to obtain an ip address. After a few min it times out and tries again. When I load the phone recovery the error message is still present.

When I use an explorer like ES explorer or Root explorer I can go to system/ and find several files & folders.
However, when going to recovery and using the TWRP File manager or by using ADB Shell the System-folder is empty except for a folder named bin/. No sign of build.prop or any other files/folders.

I hit the top button. Flash Clockworkmod recovery or what ever it said. I then backed up my Current ROM. I then downloaded Cyanogen v6.0.0 cr2. It downloaded and rebooted my phone. But It went to a screen with a Triangle w/ exclamation and a phone under it. I then hit the up vol button and camera, and now I'm at the Android system recovery page and I don't know what to do next. These are my options reboot system now apply sdcard:update.zip wipe data/factory rest wipe cache partition wipe base band data. I did click to backup current ROM and wipe data and cache.

I know that I can make a recovery zip to install packages, but I was wondering if I can make a zip that will extract and replace database files on my phone that are not packaged. The reason I want to do this is so that when I flash a new ROM, I can easily restore certain phone settings like altered APN databases.

I've been running CM nightlies as long as they've been available for my device (Samsung Captivate). After each flash though, I have to go in through Titanium Backup and uninstall a number of system apps (mail, exchange services, music, DSP manager, news & weather, dev tools) that I do not use for various reasons. I know the ROM runs fine without these elements, as I've been removing them for years now. Manually removing them wasn't such an issue until my phone received a TWRP recovery, which effectively gets me much closer to a "one-click" nightly update making the manual cleanup more of a burden to my lazy lifestyle.
I'd like to create a CWM flashable zip that contains only an update script that removes the system apk's that I specify. Using TWRP I'd like to be able to flash the update, the kernel, and my custom "cleanup" zip in that order. I know the path to all the subject apks, but I know little about scripting or creating CWM zips. my way around a bash script, but I'm not even sure if that's relevant.

"Android system recovery <3e>" when I push the "volume down + home + power button". I didn't went to "dowonload mode" but I just come with "android system recovery <3e>".
everyone just said like a simple "just try again, maybe you push the wrong button or anything" I told them I had try every thing before I ask them all and that's all didn't work.
I just wanna flash the custom rom for my galaxy s3 and rooted like I did before on my galaxy young,

My HTC Desire VC (T328d) was rooted and running Android OS 4.0.3 (ics).
In recovery mode, I accidentally formatted /system folder (from internal phone memory). This is because the recovery mode is all in chinese language and I did a huge mistake.The phone cannot boot showing HTC logo screen and no boot sound.
I've downloaded the kernel for this device at htcdev.com.I can enter recovery mode. My friend has the same device and his is not rooted yet.
