I just fugured out something the problem occured when i took a backup of my build.prop (original one) from my sd card and replaced it with the one in my system folder and forgot to add permissions to it and i restarted my phone and now its bootlooped. When it happened i tried to fix it before i factory reset my phone and lost access to recovery cuz i use to access it from adb i tried to flash a new one (build file) but i got signature verification failed so i just factory reset and lost my adb drivers so now i cant connect it to my computer to use adb commands to reboot into recovery and idk my combination for recovery it is speadtrum sc6820 .....ps. my phone is rooted and has mocor droid 2.3.5 with 4.2.2 jellybean so u know its a fake jellybean cuz its a cloned phone and i have no cwm :crying:

@BenDroid1
You can write the custom recovery to your recovery partition using dd in an android terminal emulator from the play store. You would need to know which partition holds your recovery.
For MY device (your partition is different) it would be as followed in the terminal emulator:
Code:
su
Code:
dd if=/sdcard/customrecovery.img of=/dev/block/mmcblk0p21
/dev/block/mmcblk0p20 is the partition that holds my recovery on my device - yours will be different!
You can also use this method for the boot.img towards the boot partition as well as data to data partition, and so forth.
If you have CWM and you were smart enough to create a backup of your device, then I would write the custom recovery to your recovery partition, boot in to CWM, and restore your device with your backup. Then, reboot, plug device in to your computer, allow the computer to reinstall the drivers and hopefully at this point you should be able to establish connection with adb/fastboot again.

Because right here according to your quote you mentioned that you resetted your device, lost connection to your adb. Only time you can use ADB is when your phone is running. Only way you can confirm if you lost connection with ADB is if your phone is up and running, you open up command window on pc, then run 'adb devices' and if nothing returns then you have no connection. Otherwise, there is no way to confirm if you lost connection to it. So by your quote above, you made it sound like you got around your bootloop problem but could not connect with using ADB and no longer had CWM on your device.
Try to be more clear next time lol.
Have you tried using fastboot instead of ADB?

no i havent and sorrry i ...i will be clearer when i press power plus volme up i get speadtrum factory test where u test phone hardware but no android recovery
Your phone has a bootloader. You need to access your bootloader, select fastboot, plug your device in your pc, open up command window, then type 'fastboot devices'.
If you get your device serial number returned back to you then you have connection. If it returns blank, then you do not have connection which at this point I will not be able to help you.

Hello
I think I've bricked my P760. When i want to run my phone it stuck on LG logo and can't boot to OS. Everything was fine but after installing fix to camera i could boot to OS my phone once and after reboot i can't boot to OS anymore. My phone has root, unlocked bootloader, custom recovery and custom ROM. I don't have acces to recovery. I have only acces to bootloader mode with fastboot (VOL+ + HOME + POWER). Then i have a note "Welcome to LG Fastboot Mode ". My computer detects it and automatically installs drivers (Fastboot interface (Google USB ID). But the problem is that in Device Manager it all time blinks. It's connected and immediately dissconects. I'm using original USB cable from LG charger. When i'm trying to use cmd in fastboot & adb files it's waiting for device all the time.
I don't know what I should do next :C
Pls help guys

Go through this thread http://forum.xda-developers.com/showthread.php?t=2292828 it will definitely solve your problem, from the screen-shot it seems that you are using windows 10, i'm not sure that omap4430 drivers will work on windows 10 or not, but you'll try otherwise do the process on windows 7, your phone will revive...
@Codeplex its to complicated thread.
before mine become like this my phone alway succes writing recovery via adb fastboot but now i try writing recovery via adb fastboot always filed.
flashing firmware with cmahendra method always get 15% error..
I think all dev not care anymore about our phone..,
*im not developer, neither noob i just like to share what I know*
Maybe this is a noob guide, but i did my best to share something helpful
before you go deeper, be sure to check your phone able to get into fastboot mode. If you cant, use REAL unbrick method instead
If your phone soft or hard bricked, bootloop, stuck on logo etc you know you are f***ed unless you know what should to do.
Some time ago bootlooped my phone, but i cant go to recovery, cant ADB because I forgot to enable USB debugging, my computer wont recognize my phone poperly because my phone mad at me, and my phone flickering like hell *party hard*. Maybe this is a brick not bootloop but whatever
Good friend of mine tell me what should to do
What you need:
Working PC with minimal ADB and fastboot installed //see the thread here, your phone's USB and ADB driver installed //download here if you dont have it
Working USB DATA cable
Custom recovery everything will do, as long as its compatible with your current android version. Rename the img to recovery.img
ROM you prefer everything will do, as long as its compatible with your current android version. Move to your SD Card
The power of will
Step:
1. Make sure your phone is turned off
2. Boot into fastboot mode, you will see some chinese message
3. Plug your phone to to your PC
4. Check if your PC at least know that you are pluged in your phone (check via device manager by 'plug and un-plug' your phone and check for 'appear and disappear' device , mine listed as it is was a modem.)
5. Move the recovery.img inside minimal adb and recovery folder root usually under c:/programfiles directory
6. Run the minimal adb and fastboot, check your device by using /adb devices/ command without backslash
7. If your device is not listed, dont worry. We still able to use the fastboot
8. Boot your phone into recovery mode by using /fastboot boot recovery.img/ command without backslash
9. Wait for few secs, and your phone should touched down to recovery mode.
10. Do wipe (data, dalvik, cache, system, internal)
11. Flash your prefered ROM
12. ..........???
13. Profit
Troubleshooting:
If your PC unable to recognize your phone completely, try using another usb cable, usb ports, uninstall-reinstall, plug-unplug, and make sure your phone in fastboot mode before you plug your phone to the PC.
Feel free to critics, I hope this helped you :fingers-crossed:
Thank you for all who helped me making this post.

You may need to check some things:
Your PC actually know that you have inserted your phone. It doesn't have to know it's a phone (so it can be detected as unknown device or something similar, mine is detected as a modem)
Your phone is indeed in fastboot mode, you can tell yours is in fastboot mode by a Chinese message at the bottom of the screen
Change your cable data, make sure it is a cable data, not a normal charging cable
let me know if you need some help

No os found means that you wiped your partitions like data,system. A simple nandroid restore will do

It your USB flash drive,if the screen goes black the flash drive has problems. Do you have another flash drive by any chance? I know you said the PC isn't detecting the phone but try putting it in recovery mode again and mounting all the partition and see if your flash drives work. If you have no success unfortunately you have a hard bricked device

Hi everybody,
Sorry if my post already exists and if my english is bad but i really need help...
I tried to root my honor 7 so first i unlocked bootloader successfuly, i installed TWRP too and everything seemed work very good until last step where my phone didn't boot, i stayed stuck in boot logo... Then I done a factory reset with wipe cache, dalvik, data etc...
Now the only things i'm able to do are boot on recovery mode, eRecovery and on fastboot&rescue mode. I lost adb and fastboot and i'm not able to acess to the phone so i can't put a rom on the phone to install it...
If anyone could help me it would be very nice because I'm going crazy. Thank you !
My phone was up-to-date, i can't remember witch firmware i had but i think it was Android 6.0.1

I'm not sure I understand the question but i'll try to explain.
I was not able to connect to PC apart with fastboot (reboot in fastboot mode and connect to PC). Once done, just open a terminal and type "fastboot flash boot <boot image file name>.img" then do the same with IMG (as said in this page .

Read this carefully, this will restore youre phone:
1*.)No matter what youve done with this phone it will be cleanly installed like its fresh new, cause i had couple of problems and this method worked
1.)Download the latest b396 firmware
2.)format youre SD card with basic settings via Windows ( if you have a usb stick to connect youre SD card to computer like i do, if you cant connect youre SD card to computer, use another smartphone and format youre SD card with basic settings)- simply talking just format youre SD card
3.)create --->>>dload<<<--- folder like i wrote down without the --->>><<<--- stuff on youre SD card
4.)paste the update.app file to the dload folder
5.)insert youre SD card to phone
6.)this is the moment of truth hold down volume + & - key and power key all in once until the emui logo appears WARNING: remove all keys after logo appearing WARNING: if the logo doesnt appear even after 30sec. keep still holding until the logo appears
***If you get somekind of error i can help, if it worked youre a lucky guy
