[Q] Help, my device won't boot! - Optimus One, P500, V Q&A, Help & Troubleshooting

So basically I rooted my LG p500h and installed a ROM through ROM manager, the thing is that when I rebooted the device I got stuck at the analog to the Android logo that shows up after the LG logo. I flashed an stock ROM through KDZ update software but after the program did it's thing, I did hard reset the phone and got the same problem: won't boot up and forever stuck at the android logo. I can get to emergency mode tho and when usb connected will show the battery charging up. I have searched solutions and I haven't reached one yet so everyone told me to post here and ask for some help! I hope it's not the end of my device Any help is sincerly appreciated!

Much as I hate to say it, ROM Manager is not friendly to our devices. Secondly, stay away from KDZ too. But don't panic. You do have options. You will need to use either ADB and dd commands, or fastboot and fastboot mode. Since you can't boot, most likely the ADB way won't work ATM. Both methods require either the ADB binaries or the Android SDK. An alternate method would be Android Flash Recovery. There is a link in my signature. There are complete instructions in the download. On thing, put the device in fastboot mode before connecting it to the PC.

Enter into emergency mode, BACK+VOL UP+POWER
then follow this guide to flash recovery: http://forum.xda-developers.com/showpost.php?p=15217609&postcount=3
After that enter into recovery, HOME+VOL DOWN+POWER
then wipe data/factory reset, wipe dalvik cache, wipe cache, format system then flash a rom of your choice like oxygen, cm9 present in development section.
Then reboot

Odd enough, I plugged in the device to the computer after the USB drivers got installed (following all the instructions given by the files provided), I went to the bathroom and left the cell phone unattended, just to find it boot up! weird. Anyways your advice was very helpful and very clear! Now I will figure out how to get my old ROM for my country. Thanks again!

[Q] HELP! ZTE RACER bricked after rooting!

Hi! Sorry about this rude way but I am in an emergency situation.
I have a ZTE RACER with Android 2.2.2 (official ZTE Frimware) which it keeps rebooting at the splash screen.
Before that, I did a root using SuperOneClick 2.3.3 by Shortfuse. After following the instructions (USB debug, plug-in, root) I've rebooted the phone normally (NOT with adb), and when it got after the ZTE Logo (the first one, not the splash screen and not the Android logo). The animation goes a little and freezes for a few seconds, then restarts automaticly (but not entirely, just repeats the splash screen) and reboot. Rance and repeat! I tried to unroot, but the app hangs, restarting with adb and nothing happens. adb restart command doesn't help that much. What should I do to fix it?
Additional info:
Phone recives adb commands normally.
Possibly Superuser app was leftover before unrooting and rooting again (yes I already did root, but superuser stoped working properly afer app and su files update)
Can't go to FTM Mode, ROM Manager gave me a broken CWM.
Unsure If I can install CWM manually since SD doesn't seem to get mounted.
Phone Info:
ZTE-RACER
Android 2.2.2 (FROYO_P2XXGV_V1.0.0_B2)
CWM 5.0.x (Installed with ROM Manager. Broken.)
Carrier: GR COSMOTE (that's unknown carrier for you.)
Thanks for any help.
P.S.: Does anyone here is greek and has a ZTE RACER with the official 2.2 upgrade? I need the FTM Mode.
From what you have said, it seems like you are in a soft brick not a hard one. This means that there is chance of recovery but you have to be very careful.
You weren't rude so don't worry bout that.
You may want to try a hard reset.
Now that we have identified the problem, you have the ability to try and find it yourself at least.
It is possible to manually flash the generic default 2.2 and this will restore your device.
or
turn off your phone and then press power button and volume up button.Programing will open and there is a option of reset and restore.By using volume button go to reset and restore option and then press power button and home key programing will start and your phone will reset.
Hit thanks if you found this useful.

For the first one, I don't know how since the only way I had was to reflash it with the 1-Click Update (I did that on my ZTE MF636 3G Modem).
About the second, you mean that I must use the adb command, or I just hold it down without connecting it (I am newbie to the Android), but thanks for the help. I'll keep you posted for the results.
(NOTE: 1-click update is the offline frimware updater made by ZTE.)
if the logo appears look for a solution, if nothing happens buy a new one because is a full brick

Logo appears but... I still don't get it.
Was that for CWM? Or for the phone?
CWM is broken by the ROM Manager. After installing, I tried to get in, but it got frozen to the Android logo + the red led is on. (Temporal brick).
Should I flash a working CWM to the phone?
Anyone?
If there is a working CWM recovery .img file for your device, flash that using fastboot.

a) I am not sure if it works but for sure it doesn't come from ROM Manager.
b)Where do I find fastboot and what's the command?
Anyone, please?
I think you get it when you install the SDK, along with ADB. You put your phone into fastboot mode, plug the USB into your computer, and use fastboot flash_image to flash the .img file to your device's recovery partition.
If you can boot your device into fastboot mode, search for "Android Flash Recovery" by Bill.Weckel (Windows only). That'll be the easiest way.

This command doesn't work. Is it fastboot flash recovery [image_file]?
Will somebody please help me out!
Here is the thread for Android Flash Recovery:
http://forum.xda-developers.com/showthread.php?t=1827723
Doesn't work! It does detect it, but it can't flash it (on normal boot only. On recovery/bootloader it just getting bricked). Any other options? Or I have to send it for reflashing?

[Q] LG p505 stuck at LG screen....

and nothing I do get's it to go away. I have spent the better part of 8 hours screwing around with it and can't figure it out. Here is what I know:
If you just try and turn on the phone sans power cord, it won't turn on. If you plug it it, it displays the LG screen and stops. If you hold down the power, down, home keys, then power cable, it will boot into fastboot and take fastboot commands. I have followed the procedure to flash a recovery image listed here in the forums to no avail. It will erase the recovery, flash it, but will not reboot on the reboot command. When I disconnect the data cable and reconnect, it will go right back to the LG screen. I have tried KDZ and downloaded the original rom via the Original LG Firmware tool. It will communicate with the phone if I put the phone in emergency mode via the simultaneous back and volume down button while connecting the power cable. KDZ will start to install the rom but after some time, the phone spontaneously reboots and then hangs at the LG screen. Upon reboot back into emergency, the KDZ routine finishes and says it's finished but when I reboot it goes right back to the LG screen. I have tried the kdz tool in diag and emergency modes while shaking the phone. I have tried the software update tool but it says it cant communicate properly with the phone. I don't know what else to try.
Any suggestions?
Thanks a bunch!
After you succesfully flashed the recovery using fastboot, do you try to boot into recovery manually?
If that doesn't works you could try this http://forum.xda-developers.com/showthread.php?t=1827723

By recovery do you mean clockworkmod? If so, the phone is stock, unrooted so no, if not, what do you mean and how do I do that?
Thanks a bunch!
PS, If I follow the method I found for entering recovery it goes right back to fastboot.
PS Part two, the app you link did the same thing as I did manually and did not help.... thanks anyway...

Hey jackler1, it will not allow you to install any custom recovery if your phone is still not rooted as you mentioned.
Hence using the Home+Vol-+power combo takes you to the fast boot screen.
1st thing you need to do is to root the phone, for it to allow installation of a custom recovery.
Many root tools are available for the P500 - eg Gingerbreak, Super one click.

[Completed] [GT-N7000] Stuck in manufacturer Logo, unable to enter recovery can enter download.

Is my device soft bricked?
I flashed PhilZ-cwm6-XXLTA-ATL-5.15.0.tar which worked, then I started up the phone and tried to flash CWM 6.0.4.3 touch using ROMManager, the process was a "success" but after the reboot attempt the phone was unable to boot OS nor is it able to go to Recovery mod. I am still able to enter download mod.
I tried flashing PhilZ-cwm6-XXLTA-ATL-5.15.0.tar again, but it didn't work. I can detect my phone in ADB devices and in Odin3. I am currently searching for a stock ROM for my device.
If anyone has experienced this before and knows the result already, could you tell me whether my device is lost or I can revive it somehow? Thanks in advance.
EDIT: My phone doesn't seem to go into recovery, stuck at manufacturer Logo(Not restarting); but in ADB devices I can see it in recovery mod and can see its contents in adb devices.
Solved: It booted normally after deleting update.img and cache via ADB.
Thread completed as user already founded the solution.

Unless something has changed, version 6. requires that you flash a special kernel before you can root your phone otherwise you are as you are now, stuck in a boot loop. You should probably download the factory image from Google, and then flash the system image to get rid of what you have done.. Perhaps then your phone will start normally

Thank you very much for the reply, I really do have no idea as to how to flash the factory image because i am very new in this area. Could you please recommend software and which factory image i should download, please ?? thanks very much.

Also, you mentioned a 'special kernel' what does that mean. All i want to do to my device is install cyanogenmod 12 and for that i believe it needs to be rooted, so i am really confused. What should I do know
I'm having this same problem, and unfortunately, when I start the phone on fastboot, I can not access the recovery mode in order to upload a factory image of nexus 5.
I used the new tool available her for quick flash, and now, I don't have a phone.
First, don't panic. Your phone is still very easy to recover. Unfortunately I can't get you a complete walkthrough here (for now at least), so I'll give you the main idea and you'll have to do your homework (as maybe you should have done before).
1. You need to get fastboot working on your computer. It's included in the Android sdk package, but there might be some easier way to get it. Google it. You might need drivers for your pc too. Google it as well.
2. Then you need to get into fastboot mode on your phone. To do it, hold down power button AND volume down button until it gets into fastboot mode. You will see an android on his back with the cover open. At this point, connect your phone to your pc, open a terminal on your pc and type "fastboot devices" without the quotes "". It should find your phone if fastboot is working. If it doesn't work go back to step 1.
3. Download TWRP recovery on your pc and place the img file in the same folder as your fastboot executable (not mandatory but easier). It can be found here https://dl.twrp.me/hammerhead/
4. Always in fastboot mode, type "fastboot flash recovery twrp-2.8.7.1-hammerhead.img" assuming you downloaded that file, which you should have by the way. It should install fine. If you haven't placed the file in the same directory as your fastboot executable, you will need to provide the path to your img file as well.
5. Then use the volume rocker to switch between modes and choose reboot recovery.
6. You should now be in TWRP recovery. At this point, download a custom kernel (anyone found on xda for hammerhead should do) and push it to your phone. It should be fairly simple with TWRP. Then flash your new kernel using install. It should help you get your phone booting normally. Alternatively, you can download a custom ROM like cm12.1 and flash it altogether. It will install everything needed for your phone to boot up too. Beware if flashing a ROM though, I strongly advice you to do a factory reset before flashing it. You will find that option in the wipe menu.
Hope it helps, let me know if you need further assistance.
Yesterday, I have tried everything to have my computer to recognize the "fastboot" command, and I installed like 2 or 3 different programs for that. With my old Windows 7, I have been able to push a flashed image to fix this issue, using the fastboot command, but with Windows 10, it's always telling me it's not a valid command. I'll keep trying it, otherwise, i'll have to "resurrect" my old Windows XP computer.
Also, I noticed now that, while trying to install the fastboot, as per some files that I could download, but no file has been copied into my computer, not even if I run it as admin.
fixed. but no RECOVERY mode options....
Hi Guys,
Thank you very much for the help, I have finally recovered the phone and running android 6.0 MRA58N but it is not rooted. Now if you don't mind could you teach me how to root because i have checked lots of videos and tuts but none worked for me...
IMPORTANT:
when i am in recovery mode why cannot I access options even when i press volume up + power button and release them at the same time...????
Thanks in advance.
Just flash a custom recovery via fastboot. Just make sure your bootloader is unlocked. Can't link though.
hi guys i have used nexus 5 mobile with cyanogenmod 14.1 .It worked properly in 1 year. after that suddenly switched off and it not properly boot up .i try to switch on my mobile , first it show google with unlock logo properly and when it show cyanogenmod logo it stuck and again show google with unlock logo....i try recovery mode to wipe and flash the same rom ....the process is interrupt at middle stage and again show the google..i try lots of time . after few try that process finished completely without interrupt. then use my mobile 1 day same as i used first time root. after that same problem occur on my mobile ..so help me guys
@[email protected], possible power button problem?

Stuck on bootloop.

I'm using Lenovo K6 Power... And wished to use custom ROM. So did all the procedures(ADB, TWRP, SuperSu, ETC). Now, at the time of installing custom ROM you have to wipe all data including your phone's UI (ROM) so I did that. Now I tried to Install that custom ROM several time but it didn't install, I don't know why. So I clicked on reboot button... And then boom... My phone is stuck at Lenovo logo. I know I made this mistake. I didn't understand that, How can a phone reboot if it's original OS is deleted.
It can't even enter in TWRP recovery mode. Fastboot can be seen sometimes.
So please me with this, I'm completely new in this. Read so many forums and watched so many videos on YouTube for this. But they didn't help me. Any help will be appreciated. Thank You.
Highlights-
1. Stuck at Booting Animation.
2. Can't enter into TWRP recovery mode any how.
3. Fastboot Appears on top sometimes.

If phone gets powered on, then its bootloader get run ( comparable to UEFI/BIOS in Windows computer ) what , when its tasks have finished, tries to start/run Android OS.

Is not bad: many do not understand
Eeach mobile device can get run, but without an OS it stops after bootloader finished, because it's just a box of bits.
simple
when bootloader shows up, or bring it up with key combinations, connect phone to PC, and in fastboot/bootloader (on phone) type
fastboot reboot recovery
or if not work then:
fastboot boot c:\twrp.img
and do the rest via twrp, like flashing custom ROM again, or just flash stock ROM
