Hello everyone !
I have big troubles with my Lg g2 d802.
Yesterday i want to intall crdroid 5.0 on my Lg g2 on Official 4.4.2, so i've:
Root my phone
Install CWM Manager
Set CWM Recovery
Reboot in recovery
Use ADB Mode
Use ADB on my PC to send crDroid zip by sideload
During sideload, after full download, there was an error assert failed. So installation failed, and i've decided to reboot my phone.
Problem is here, my phone boot, display LG Logo and after 5 seconds, Lg Logo with "security error" message, then stop alone and reboot again, and again.
I have tried following procedures :
Power off completely my phone and then Volume down+PWR to enter in recovery : FAIL
Volume Up and then put USB cable to enter download mode : FAIL
Connect with USB on Ubuntu to try to reset .img files : FAIL (Phone invisible on my pc, even not recognize)
So i cannot go to Recovery Mode, Download Mode and my phone isn't recognize on PC.
I don't have any other ideas and i am here to asking help .
Thxs for reading, and i pray for a miracle !

Recently I was tried to update mobile firmware (latest Kraft-A6000-S_S014_150730) by OTA update (via system settings->about phone->system update), that time my mobile was soft bricked. I downloaded firmware and installed then some time after got some options menu. And I attached that problem as picture.
Before that I rooted my mobile using KINGROOT apk v4.0 , there after I did unroot again using in the same app.
I thought unrooted mobile does not affect by system update (any firmware or OTA update by LENOVO). But unfortunately my mobile got problem.
I didn't took any backup before that. I don't know anything about CWM backup and all. I know only the root and unroot using KINGROOT app.
I need to recover my mobile back or tell me how to install LENOVO A6000 PLUS stock ROM or any other way is there tell me to solve the problem. Please guide me step by step process or any video link there it was little better to understand for me.
Please help me, it will be appreciated. Thanks.

3. copy this TWRP recovery.img in that minimal adb folder(C:\minimal adb). Link here. http://forum.xda-developers.com/android/development/twrp-lenovo-a6000-a6000-t3156149
4. now type fastboot devices in command prompt
5. It will show list of devices attached, it will show only if your phone is in fastboot mode.
6. then enter the following command: fastboot boot recovery.img

10. Copy lenovo stock rom zip file to your phone. (Search google for Stock ROM of Lenovo A6000)

Bro Did you try updating your device. And how did you root your device by using kingroot or superuser? I just rooted my lenovo a6000 plus by superuser using cwm. I just wanna know can i unroot my device by the native superuser full unroot option and install ota when lolipop is available without bricking my device?
I ve heard that people who rooted their lenovo a6000 plus with kingroot had problems to unroot and install ota updates is it the same case with superuser?
Same Here!!

Stock recovery for your phone is on the first page of this thread. Download the file, rename it to recovery.img and then flash it using fastboot.
Will this work for a6000 as well ??
phone soft bricked?? plz help
I think my lenovo a6000 plus has been softbricked as it doesn't get pass the logo screen. also recovery mode is not opening ( tried every combination). Help me with this. This phone has really checked up my nerves. the reason for flashing this phone as it had a problem of automatically downloading apps without consent, and video apps popping out in the middle of night(time service, monkey test apps), so the only best solution i found was to flash it( tried every other possibility- factory reset, password change...etc everything). Now it has died on me, can't get pass the logo screen. Also connecting the phone to pc gives me multiple drive partitions. Please help.
Try to flash any custom rom..but first flash custom recovery using minimal and fastboot

Help with Rooting Nokia 5 (Can't bypass the checking for update process)

Hi!
I am newbies to all of these but I will try to explain.
LinkA : https://forum.xda-developers.com/nokia-5/how-to/guide-how-to-downgrade-official-oreo-to-t3746007
LinkB : https://forum.xda-developers.com/nokia-5/how-to/guide-ta-1053-downgrade-official-oreo-t3893053
LinkC : https://forum.xda-developers.com/nokia-5/how-to/root-nokia-5-android-8-1-t3831303
I have Nokia5 with android Oreo and I want to root it so I browse a lots of tutorial with zero prior knowledge and follow them.
1. I downgrade to nougat by following LinkA and LinkB <-- I use rom A02 from this guide.
2. enter download mode on my phone
3. unlock bootloader temporarily by using "Unlock Bootloader.bat" from the script mentoined in this guide LinkC
4. flash TWRP v3.2.3, v3.3.1 img files-- > I tried both but none of them work
The problem is after I flash it using "twrp flashing.bat" from the same script. I pressed power up and power button together until the phone vibrate but it just boot to the default rom that I downgraded to.
How can I boot to the newly installed TWRP recovery ?
Moreover, I can't enable USB debugging because I can't skip checking for update screen in default rom. Nokia want me to upgrade to Pie or whatever their latest version is. I tried removing sim/disconnecting wifi but it won't work. The only way I can access the phone right now is to update to Pie which is opposite to what I have been trying to do.
Edited : I tried updating as system suggested but it won't start. I am unable to use this phone now T_T
Edited 2 : I tried to flash new nb0 rom but I can't access recovery mode. It's all black. I don't know what to do now it's dead end pls help!
Anyway to fix this problem?
Thank you in advance

Hello!, I hope is not late for the help. Follow my steeps (sorry for my eglish)
1. Download the firmware for ur mobile (U can do it with a program called Frija, is the fastest way).
2. Download ODIN V. 3.10.7 (Is the best version for your model)
3. Open ODIN and put the ROM, select the option: Nand Erase All.
4. Flash!
5. If all goes fine congrats, but if ur phone is stuck in SAMSUNG logo go to step 6.
6. Put ur phone in ODIN mode again, and re flash but don't select Nand Erase this time.
7. Wait for 100% then, turno off ur phone, and enter recovery mode (VolUp + Home + Power)
8. Select in recovery: Wipe data factory and Wipe Cache Partition.
9. Restart ur Phone and wait. If all goes fine: Congrats.
i support what "cc33wm" wrote,
also, at least on mine i had to unlock the bootloader first in order to root it properly(i also installed twrp recovery), so it might also be your case
