hey guys! I really need help. Actually i have a LG L70 D325 phone and i rooted it few days ago. After that, i installed CMW recovery and i also instaled ROM Manager. I used ROM Manager to install CyanogenMod 12.1 and after that, i installed GApps. As I didnt like the CyanogenMod 12.1 apps, i installed "Cleanser Mod 2.0" . I ran this with ROM Manager and i removed all app in cyanogenMod 12.1. (well, there was a list and i just selected everything. After that, i reboot it and it got stuck on" Android is starting.. starting apps".. its not starting. I want to boot on CWM recovery again but its not working ! I read about volume keys and power button (I tried everything !!), but its not going on CWM recovery !!!. It just boot the "LG logo" again and again till i let go and it continues showing the cyanogen logo and eventually gets stuck on "Android is starting.. ".. i tried connecting it to pc by USB but my pc is not recognising cause the phone is switched off i guess !
Please help me ! I really need my mobile phone !!!
Hi there,
Please make sure you can access Download Mode by turning off your phone, then hold Volume Up and plugging in your USB cable.
After that please read carefully this tutorial and see if you can flash stock firmware thru that tool.

Additional info: [Q] How to recover LG l70 D320N?
Hello. Am in Mali with an Lg G3 16GB. I looked for solution to my download mode not working but no one replied. My g3 is dead,Ihave never tried update or root or... but now it's completely dead and when I normal boot it,it shows just black screen (No lg logo or any error report),just the black lit screen. Can't flash 'coz download mode not coming. I tried many tools but...failure. As this seems not to be resolvable,is there anyone who has an update.zip backuped from similar phone for me as my lg can access recovery mode. I'll try to apply update with sd card. Or is there any way or repairing download mode with adb sideload?
As far as ]download mode is concerned when I try to access it drivers are installed but the screen keeps black and it displays Mtk65XX installed and adb android phone can be also seen. Please,need to be rescued. Am now without hope as there is no warranty anymore.

Hi guys. My LG x145 has been bootlooping since Monday and I can't seem to fix it.
My brother tried to flash it with CM 11 and maybe messed with the steps and its been bootlooping since.
We have tested the phone to see if it's bootlooping on its own. We removed the battery for an amount of time then return it in place to see if the phone will turn itself on. It didn't so flashing a rom to the phone and messing up the process must have lead to the device bootlooping.
We can't:
enter recovery mode
enter download mode
enter bootloader
Whenever we tried booting the phone to recovery mode, the phone would start up normally and display the LG logo with a note below it that it is booting up in recovery mode. But after a few seconds, it would turn itself off and on again.
--------
We tried:
using adb to boot in the aforementioned boot states
flashing it with lg flash tool 2014
following some posted answers in some forums with the use of lg mobile support and lg pc suite
-------
The problem with the above is that the device can't be detected despite having installed the drivers when I rooted the phone last year. I rooted the phone using my laptop and kingo root.
Any form of help is much appreciated. Thanks in advance.

Hi
Thank you for using XDA Assist
Sorry for the inconvenience. Cant find any specific thread for your device but you may post here for now

Thank you..
How can i fix this? Need help
Flash again using LG Flash Tool, use D838 international version of Lollipop stock rom
Go to 'Download Mode'
Set the flash tool to CDMA+Emergency
Make sure you do everything OFFLINE
My phone got stuck at 90% while flashing D838 ROM. Now it does not open anymore - only the LG logo shows off and on and can no longer be detected by my PC. My phone now is on a 'bootloop" mode. And I can no longer go to Download mode so I can flash anew.
Any help from our Masters out there?
TIA.

Take a look at my thread for LG V20, read fastboot tutorial in particular. Most knowledge on my thread applies to LG-D838 which I own too. Just change things accordingly. For instance, instead of LG UP tool use LG Flash tool.
Once you read the articles, you would be your own master. Good Luck.
