hi bro
when you are on bootloader and if you tried to get into fastboot : it get freeze before you enter into fastboot mode or after ?
and try to plug your phone on pc even if it is freezing maybé you can still use fastboot or ADB command !!

Hello botioni. First of all make sure you have installed adv drivers and Google's usb driver to make your phone be recognised from the pc. Also I would like to ask if you are able to enter recovery, cause as you have mentioned in the thread you can't access fastboot( freezing issues). If you can then there are three things you must do.. The first one is to fully wipe you phone storage and system then follow these steps. Download the mini ask ( search it on Google) and when you do this go to the folder you downloaded and open a command window with Shift+right click. On the cmd window write the following:
adb shell
mkdir -p data/media/0
Exit
Then restart recovery in order for data to be mounted
Assuming that you have downloaded a Rom for your phone you can install it either by pushing it using the command adb push Rom.zip (where Rom zip your Rom's name) or you can use adb sideload Rom.zip from the sideload function of the recovery ( advanced--> sideload). Hope I helped
Did the suggestion mentioned above worked for anyone?
Hi, need your help if possible. Trying to unbrick my phone via this tutorial:
https://www.youtube.com/watch?v=boyU1MnI7HU
When i need to flash ROM with "adb sideload" i get error "device not found"
fastboot devices give my phone code, i can flash recovery image without problems. only ADB SIDELOAD GIVE ME ERROR
Help me out please.
or tell me some other was to fix brick
PS: can be this coz of USB debugging is not enabled? cannot enable coz cannot start phone
If debuging usb is not enable adb wont detect your device :/

What does typing "adb devices" give you?

For using ADB sideload your phone must be booted to custom recovery e.g TWRP or CWM and SIDELOAD mode must be started manually.
Hello,
Recently I flashed a CWM file for 'Lava Iris X1' found on this site for my android 'Lava Iris X1 Grand'. Now my phone is stuck in a bootloop. For some reason i cant enter recovery mode even before my phone was stuck in a bootloop. I am not sure whether my phone has USB debugging enabled or not. I rooted my android with KingRoot before all this happened. I have downloaded your Minimal Adb and Fastboot but it cant find my device.
Overall problem:
1) Phone Stuck in Bootloop
2)USB debugging enabled ? Not sure
3) Can't enter recovery mode
4) ADB wont find my device
Note : When I used Minimal Adb and Fastboot, I typed 'fastboot devices' and some numbers appear:
0123456789ABCDEF devices
but when I used the command 'adb devices' my device is not shown:
List of devices attached
I have a backup at my phone through the Flashify app but since recovery mode cant show I cant recover it. I also need a some flash recovery images.
Please help me out here. I don't know what else to do.
Thank You in advance
Fixed
Nevermind guys, i was able to get my phone out of bootloop using SP Flash Tool.
Now all I have to do is restore IMEI.

Hi,
dear xda senior member please help me on rooting Gionee S6s android smartphone. Actually i tried to root this device but i struck on bootloop.
I make developer tab on as described and turned on the USB debugging and OEM unlock.
i have downloaded twrp-2.8.6.0-m4 from twrp website.
as started rooting process through adb command prompt as
"adb reboot bootloader" - to boot into bootloader.
after booting into bootloader i typed "fastboot flash recovery twrp-2.8.6.0-m4.img" then an error occured saying that failed recovery then i googled it on xda forum and performed "fastboot oem unlock" through command prompt everything was going smooth until i typed "fastboot reboot" - to reboot my device then as a sudden it looped several times.
and i don't know how to stop it as this device don't have removable battery. My intention was to flash supersu zip file through recovery but i failed and loss my device. may be i downloaded incompatible twrp recovery further i didn't find any website to download firmware of this device to flash it through SP flash tool.
please help me revive it again.
Thank You.

As there isn't a dedicated forum for your device here try posting your query is in:
> Android Development and Hacking > Android Q&A,Help and Troubleshooting.
You can hopefully find some support there.
Good luck
Hello,
I am trying to install CM on my old Android tablet - Lenovo TAB 2 A7-30DC, Android version : 5.0.1 , Kernel version: 3.10.54 . I have downloaded the zip cm-12.1-Tab2A710F-20210102-1707.zip , but I cant install it . I have root on the tablet, installed flashify, twrp, but I cannot unlock the bootloader - I dont have OEM unlocking as an option in Developer Mode menu. Please let me know what should be my next steps. Thank you.
Download "ADB fastboot tools"
Download and Extract the Downloaded ADB fastboot Zip file on your PC.
Now connect your phone to Computer using USB Cable.
When you connect your Phone to Computer, please wait until all the drivers get installed.
In your ADB fastboot folder open a command prompt window by pressing Shift Key + Right Mouse Click Now type the command in your command window:
-----------------------
adb devices
------------------------
If you see a pop up to allow USB Debugging on your phone, Click OK
Now type the command below to reboot your phone to bootloader:
-------------------------------------
adb reboot bootloader
-------------------------------------
Once your phone reboot into bootloader, make sure your phone shows the bootloader locked and then type the command below to make sure fastboot drivers are installed properly.
-------------------------------------
fastboot devices
-------------------------------------
This command will list the connected devices. If your phones serial number shows up you are good to go and may continue. If the phone is NOT listed this indicates that your drivers are not installed correctly. In order for you to continue you must fix your drivers so that your phone is listed under fastboot devices.If the phone has been recognized by the command above, proceed to unlocking the bootloader with the following command:
(Remember that this step will wipe EVERYTHING off the phone)
-------------------------------------
fastboot oem unlock
-------------------------------------
After the above command has finished executing, run the following:
---------------------------
fastboot reboot
---------------------------
The phone will reboot. Wait until the phone has fully booted up into android, and enjoy.
The link you posted is the only link I found on the internet that is not dead. It is impossible to find some link for custom rom and twrp that works. I have the same tablet. I unlocked the bootloader and that’s all I managed to do.

I have this problem too. And I have another problem my device recognizes my tab when I type adb devices but it doesn't recognize it in fastboot mode. I have installed all drivers I don't know what else to do.
