Hello!
Today I decided to root my LG P880 (Optimus 4X HD) and get in trouble.
What I did to get in trouble?
I looked at the google how to root my phone and found one way. I downloaded zip folder and extracted it on my desktop then in my phone got at the recovery menu apply update from ADB and run on my desktop bat file. All was okey restarted my phone and got superuser icon. Next I tried to put clockworkmode on my phone I think by this turtorial (I have checked so many topic I am not 100% sure) http://forum.xda-developers.com/showthread.php?t=2298420 Then I got problem.
Problem:
I am stuck at the boot where LG logo appears and keep loading for ever.
I guess problem is that I did not research enough and didnt unlock bootload before putting CWM. Could it be the problem and how to solve it?
What I have tried:
Ofcourse I tried to make bootload unlock, root again, install another CWM nothing helped I wiped cache and all data I restarted phone and pc. As I understood to make bootload unlock I have to do something with adb. I downloaded it and extracted ADB folder and disk C and Opened it with CMD. What is interesting almost none of ADB commands dont work I keep getting error: closed after almost all commands like: adb, shell, adb reboot, adb usb etc. I tried to adb kill-server and start it all over again nothing helped but adb devices command work and it found my phone. I am not 100 % sure but those commands when I tried to do CWM worked fine (I put link how I tried to make CWM some lines up)
su
cat /mnt/sdcard/recovery.img >/dev/block/mmcblk0p1
sync
but when I tried to do this again I cant do it
I am using windows 8.1 btw
Maybe I can flash basic rom or something to make my phone work again? Looking forward to some suggestions

Hey folks!
Again a problem with my little phone.
Today I got similar reboots, after about 5 it got stuck at the bootscreen.
Tried to wipe cache+dalvik, booting it up again, but after it prepared all apps it stucks at the "Starting Apps" window..
Also flashed another kernel and recovery. Nothing worked so far..
Any help, because I don't want to wipe data because I made some important photos today and I don't wanna miss then..
Thanks in advance,
RS

First of all you connect your phone to PC and try to copy all the content of /sdcard to your PC. If it doesn't work reboot your phone to fastboot and connect it to your PC with CMD (in fastboot folder) running and enter the command "adb pull /sdcard C:/" without quotes, Also you can replace C:/ to any address where you would like to copy all your SD data.
After that you can flash any ROM to get your device in working condition.
If you have any query do ask or you may end up losing all your data.

Why don't you try the fastboot method.
Put your phone into Fastboot by pressing volume down+power button. Connect it to your PC, fastboot would recognize it for sure. You then enter the command. You can even use adb from fastboot.

It just says "device not found" when using adb.
with fastboot I can flash things but can't pull or?

Is your boot loader unlocked, if not you'll have to unlock it first (but doing so will void your warranty).
Assuming that you have a unlocked device follow the steps below to get all your data. (I myself tried and it worked, so it must work on your device also)
1. Make sure you have installed drivers for your Moto G, if not then do it.
2. Download the adb file to access your phone during fast boot.
3. Download the TWRP recovery 2.7.0.0 by dhacker for falcon (Moto G) on your PC and copy it in the adb folder.
4. Rename the downloaded file to "recovery.img" without quotes.
5. Connect you phone in fastboot mode to your PC and flash the recovery by command "fastboot flash recovery recovery. img" without quotes.
7. On your phone then go to recovery option and press volume up key until phone vibrates. The phone will then go to recovery mode.
8. On your PC, in command prompt(adb) enter command "adb pull /data/media/0/ C:\Moto" without quotes. The process will start and may take hours depending on no's of file and their size.
P.S. I won't be able to answer any more of your question as I won't have data connection any more. I'm sure if you will follow all the steps properly, you will get all your data. If you can't understand anything then just Google it.
Phone doesn't proceed from boot animation!
Guys!
This would be my 1st time here. I've never faced any sort of problem with any of my android devices but this one.
My phone got lost a week back. So, I used "android device manager" to wipe/lock the phone but I think it didn't as the phone was switched off all this while.
So, some gentleman found my phone and returned it to me just today. I put it up for charging. It popped up 0% battery screen and turned on after 10-15min.
As soon as the boot animation(earth/buildings) finished it jumped to a black screen.
It has been on charging for last 3 hours.
So my questions are
1) Can I make back up of the data without turning it on/formatting it?
2) How can I make it to work?
Thanks a lot in advance!

@vjsharma89 :I have posted the answer in your thread.
And after you had backuped your data, factory reset your phone from fastboot by choosing factory option and then reboot it. Or should work fine.
delete this pls, wrong thread
I see that there are other threads for this and I have read through them but they don't seem to be helping. I was in the middle of using the Nexus Toolkit to install a Rom when the program temporarily booted TWRP after it removed old os and then it stopped working and I went to reboot from the temporary boot when it told me I had no OS. Because I do not have a ROM my computer does not detect ADB status so I cannot seem to get anytging on the device. I also can seem to get the sideload to work. I am not quite sure how to use the CMD for this and I have used other threads suggestions like starting cmd in the folder that has the rom i want to flash and the typing the adb commands but it doesn't seem to work. Can someone help please?
STOP USING TOOLKITS!
If you can't get adb to work, I suggest following this thread to get it working: http://forum.xda-developers.com/showthread.php?t=2588979
Thank you, but my adb drivers are installed. my device can only enter fastboot and recovery so even now with that tool I dont know how to install an os back on my device.
Just flash the images from fastboot. There are a thousand posts on how to do this here.
"fastboot flash system system.img"
Hi there,
I had my HTC One S rooted, S-OFF, unlocked, with SuperCID running MaximusHD and I wanted to reinstall a fresh version of it to give it to my father. However, I went too fast and wiped absolutely everything. So now, I'm stuck on the startup screen (with the warning message in red) with no OS and I can't reboot into recovery (wether using hard keys or fastboot) as I can't switch off my phone. What do I need to do in this case? It's plugged to my computer but, of course, as it's stuck on the startup screen, it doesn't recognize it.
Thanks in advance.
Small update: I managed to turn it off but I still can't get it recognized by my computer. I will try to uninstall all drivers for now, I'll get back here as soon as I have time to do that. Hopefully someone will have an idea by then
Flash the recovery from my signature. It will enable USB mounting in recovery mode for hboot 2.16. Just be sure to flash the dm version.
The thing is I can't flash anything since I can't transfer anything to my phone.
Right now, what I've done is reinstalling drivers properly (I get the mention "FASTBOOT USB" in bootloader) but I can't do anything with One S toolkit v4 for example. I managed to get adb commands working and tried to push Maximus ROM through ADB but I got a protocol failure message
Edit: oh wait, it's been transferred anyway.
Do you still have the folder from the install package archive? If yes, open the cmd console and go to the package folder. If it's like in my case "D:\Root" you got to type
Code:
d:
and press enter. Then you got to type
Code:
cd
hit space, repeat pressing tab until it says
Code:
cd Root
and hit enter, again. Then plug in your phone, put it into fastboot usb mode and type
Code:
fastboot devices
into the cmd console and hit enter, once more. If everything is working you should get a list with attached devices which shows your phone.
If your phone isn't listed try another usb port or another cable or if nothing else works another computer.
Next download the TWRP version from my signature, rename it to recovery.img an put it into the install package folder. Then enter
Code:
fastboot flash recovery recovery.img
into the cmd console and press enter for one last time.
TWRP 2.8.0.1-dm should be installed now and you should be able to mount your phone as mtp in recovery mode.
It's all good now! I could get ADB/Fastboot working and could reinstall a fresh Maximus on my One S. I can now safely give it to my father and enjoy my new Z3 Compact. I'll probably install your TWRP anyway though.
Thanks for your help!
Your welcome. Actually it's not my work so it's not "my" TWRP. I've found some mistakes in my last answer cause I'm in a little hurry right now. Going to correct it later for the case that someone else has a similiar problem...
Edit: My previous answer is corrected now.
I am new to this (clearly heh) and wanted to put CM12 on my OPO, as it just arrived today and CM11 is a bit dated.
So after 101 issues I got TWRP installed, great!
However I messed it up by wiping my OS off the phone, leaving me with just access to TWRP and nothing else.
I was reading about ADB, but I cannot get the ADB sideload to start on my phone (it just hangs...).
ADB also does not detect my phone when I do an ADB push.
Any help is appreciated :'(

If you are able to get into TWRP then this link http://forum.xda-developers.com/oneplus-one/general/guides-bacon-timmaaas-how-to-guides-t2839471 will surely help you
- Install your device drivers first (If they are installed properly, then only skip this)
- Once adb and fastboot files are loaded on your computer, open command prompt and type command "fastboot devices". If you see your device serial number on the prompt, you are good to proceed ahead with flashing procedure.
- I recommend you to flash fastboot images of CMOS12 using that link.
I had a bit of a problem with CM and it kept saying trebuchet had stopped working. (This is after the phone had been running fine for a whole year with CM. Then the phone kept restarting and saying trebuchet had stopped working and it would constantly restart until it calmed down. I decided to install and alternative launcher but the problem didn't totally go.
Thereafter I decided to delete trebuchet from root and boom the phone never calmed down and kept restarting. Eventually I tried restoring factor settings and it says now that there's no OS.
I had TWRP installed before but now when I've tried to install the latest one, it doesn't show any files on the OTG. I've put twrp on the SD along with a rom as well but nothing shows at all.
Can someone help in simple terms?

Use adb commands to flash TWRP (Put your TWRP image in the same folder on your pc as your adb and enter each command separately):
adb reboot bootloader
fastboot flash recovery twrp.img (latest version is 3.1.1-0-peregrine, remame it to twrp.img - if that doesn't work rename twrp to recovery.img and try that).
fastboot reboot
If that works, restore you last known good working backup or try re-installing your stock rom.

Install or re-install your Motorola Device Manager on your pc from this link: https://mobilesupport.lenovo.com/us/en/solution/MS88481
Check in your pc Device Manager to see if your device is connected and recognized properly when you plug in the USB cable.
In the folder where your adb and fastboot files are, open a command prompt and enter adb devices to see if the phone is recognized now in adb. If it is, proceed as suggested earlier.

Go to this link (https://forum.xda-developers.com/moto-g/4g-development/rom-stock-motorola-4g-lollipop-rom-t3142816) and download the correct untouched rom for your phone model and transfer it to your sd card or internal memory.
Then try this command: fastboot boot recovery.img or fastboot boot twrp.img
and follow the directions exactly in the op in that thread to flash the rom.

Absolutely no idea how but I managed to get one of the CM roms sideloaded and even though when i chose to reboot it said no OS. I've got it going, however I've forgotten to put gapps on so I'll try that now. Later on I'll try sideload stock rom or something and see how that goes. Thanks for the help so far! :good:

The problem with CM roms is they're not really being updated anymore - just one of the problems I have with a lot of custom roms besides the bugs, etc., etc.
If you're hell bent on a custom rom, I would check out this one: [ROM][OFFICIAL][Peregrine][7.X] LineageOS 14.1 at https://forum.xda-developers.com/moto-g/4g-development/rom-cyanogenmod-14-0-t3469103
Lineage is the new go-to from CM. I personally would go back to stock first, however, to ensure everything is restored properly before installing it.
It's being updated regularly currently.
I just had a old CM rom downloaded from before hence I went to that lol. I'm trying lineage for now but I've also downloads the stock ROM. Whatever will keep the phone going
