did "clear cache" from recovery menu helped?
can you use fastboot with it?
if yes then the idea is to boot it from usb to adb shell and than copy all data to sdcard.
basically same idea as boot broken PC from recovery CD.

did you hold volume button to enter fastboot?
it is not the same as recovery - sometimes it is vol-down when recovery is vol-up.
if you enter fastboot properly for you it will looks like if phone is stuck at logo.

Moto G Freezes on startup logo and recovery logo screen

Hi guys,
I have a rooted Device with CM and TWRP installed, but someting happenend using the device and my Moto G got stuck on startup logo and Recovery TWRP logo, with adb I have acess to adb shell but everything else like adb reboot bootloader etc doesn't seems to work, with adb shell I have realized that the TWRP wasn't running 'cause when I use the interface on shell I get this message
$twrp wipe cache
"TWRP does not appear to be running. Waiting for TWRP to start"
Is there any way to install a new recovery via adb shell or reinstall a new rom, factory reset or something like that to make my cellphone work again?
Thanks,
If you are okay to wipe internal storage, the following fastboot command will probably make TWRP load again:
fastboot erase userdata​
fastboot flash recovery newrecovery.img - is a way to reflash recovery, however the above command may still be required.
The problem is that with fastboot the device is not recognized, only when I open the recovery mode...
The logo freezes but the device is reconigzed with adb devices...

I meant what OS on PC are you using. Stop adding the phrase 'twrp' - type the command as I wrote it.

There are many threads on Win10 and usb driver issues. If you don't want to try to fix fastboot on Windows, you could boot into a Ubuntu Linux LiveCD and install fastboot there.

Guys the problem was that I've not installed the drivers before, after doing this, I just installed the stock rom from motorola.

Install the Minimal Fastboot & ADB package and the Motorola USB drivers, use the mfastboot package and install the stock ROM as per the instructions provided, but ignore the disassembly part, unless you have your phone does not respond to keypresses.

Installed the wrong ROM

Recently I installed a custom ROM that is meant to be installed on a Huawei P8, for my Huawei P8 lite as my new OS because I accidentally deleted my whole OS. When I plug my mobile phone to a power source it shows the Huawei logo, I cannot get it into fastboot/rescue mode. If I try the dload folder to sd-card method it will not do anything. Does anyone know what to do.
Flash the stock firmware. I'm 100% sure your problem would be solved.

Is the device recognized by PC? If not, what is device manager labeling the device as?
If it connects to PC and is recognized you can.........
Use adb to clear cache and dalvik/ART cache, then see if the device will boot to recovery or fastboot, if not then power the device off and remove the battery then reinsert the battery(if it has a removable battery). Then leave the device off and connect it to PC then open a adb terminal and type:
adb reboot bootloader (press enter, sometimes the deamon has to start, if nothing happens then type adb reboot bootloader a second time, some devices can be booted from a powered off state with adb)
If that doesn't work try typing:
adb reboot fastboot (press enter).
If none of that works to boot fastboot then try turning the device on, when it gets to the logo, connect the device to PC, open a adb terminal and type:
adb devices (press enter, if it returns a serial number the device is recognized)
Then type:
adb reboot bootloader (press enter and it may boot to fastboot)
Or type:
adb reboot fastboot (press enter)
Or type:
reboot fastboot (press enter)
If none of that gets you to fastboot and you can't boot it manually with the buttons then you're bricked, its not hardbricked though because it boots to logo so that means bootloader is at least there even if it is corrupted and whether anything else is there or works or not.
Whatever you flashed must have had some differences in partitions that flashed over your partitions in places that weren't correct for your device, its more than just the software not being for your device, it is structured completely different than your device.
You've got to get to fastboot someway to flash the stock firmware, that's the only thing I see being able to correct your partitions and put the .imgs in the places they are meant to go.
There is also the possibility that you can download your stock firmware, then extract the kernel(Zimage, its sometimes bundled with/called boot.img or recovery.img, depending on device and android version), the boot.img, the recovery.img and the system.img and then do some research on your device model number and find out which partition(mmcblk0) each of those imgs go in(I could tell you how to use adb to find the partitions but that wouldn't help if flashing the wrong things has screwed up their placements). Then, if adb is working with the device you can use the dd command to manually push the boot.img to its mmcblk0, the recovery.img to its mmcblk0 and the system.img to its mmcblk0.
I would start with dd-ing the recovery, then seeing if it will boot to recovery, if the recovery is a custom recovery and you have a nandroid backup or a correct ROM zip, try restoring or flashing. If it doesn't then dd the boot.img to its mmcblk0 and see if it boots to recovery, if not, dd the system.img to its mmcblk0, you can repeat this process with each of the .imgs in your stock firmware. Maybe if you can push enough to the device it will restore some functionality that will allow you to get booted to a state will allow you to completely reflash the device.
If the confused you then I might have confused myself typing it, lol.

TWRP recovery menu not showing

hi, im new in this android arena and this is my first time using smartphone so please forgive my noobness.
i want to root my phone Xiaomi Redmi 5A and i follow some tutorial on youtube where he told to use Minimal ADB & fastboot, TWRP, lazyflasher noverity and lastly Magisk.
im flashing my phone using this command on ADB:
fastboot devices
fastboot flash recovery twrp.img
fastboot reboot
i guess this is it so im rebooting my phone to get into twrp recovery mode by pressing volume up+power but it showed xiaomi stock recovery instead not twrp recovery.
so what i do wrong that i cannot get into twrp recovery menu?
please help me

Is the TWRP flash successful?
Ensure that your mobile drivers are installed properly on your pc and that you've enabled USB debugging.
Now after connecting your device to the computer :
1)open adb
2)type adb devices, if it shows a serial number then proceed
3)adb reboot bootloader
4)fastboot flash recovery xxxx.img
After this, remove the USB and reboot to recovery by Holding the appropriate combination of keys.
If you reboot your device first, and then power off and reboot to recovery, you will still get stock recovery.

I bricked my device. Rebooting the system from TWRP only gets me back into TWRP.
Am afraid I will have to flash a new rom.
Does anyone know where to download a working rom for TB-X065F
Help much appreciated.

Easiest thing to do is use LMSA. It's available on Lenovo's support page: https://pcsupport.lenovo.com/au/en/...r-list/component?name=Software and Utilities.

I can download the ROM through LMSA, but not flash it.
Trying to do so yields a "complete" message from LMSA after only a few seconds, but then rebooting the device only gets me back into TWRP.
I also tried to flash all system_xx.img from the ROM using fastboot flash system system_xx.img ,
and to flash all vendor_xx.img from the ROM using fastboot flash vendor vendor_xx.img.
Fastboot performs this operation, but then rebooting gets me back into TWRP again.

Tough one! Try this. It will wipe your data partition, though.
If it will let you, power down the tablet for about 10mins. Then boot into TWRP. Go to "Wipe" and swipe for Data/Factory Reset. Reboot.
If the M10 still won't boot, in TWRP re-format Data (by typing 'yes' under Wipe->Format Data), and wipe cache and Dalvik Cache. I think dalvik is under Wipe->Advanced. Factory reset again. Reboot.
As an absolute last resort, you might try fixing permissions in TWRP under "Advanced". But I don't think that's going to do much, because you haven't booted the ROM successfully yet.
Hope one of these works for you. Let us know what worked for you. If nothing works, PM me and we'll try some other things.

I followed the instructions but on the last step of rebooting to system the device restarts, shows the Lenovo logo then it goes to a black / blanks screen. It appears to have shut down. I must hold the power button for several seconds before it wakes up (or restarts?) and does this all over again -- shows the Lenovo logo then black screen.
For the record the device was already rooted with Magisk. I was just trying to do a TWRP backup but found /data mounting errors so tried following steps 6 & 7. At the moment the device refuses to boot up. I am unable to get back into Recovery Mode. The ONLY thing i can do is get into FASTBOOT mode and issue commands from CLI.
The following hardware key combos produce the same results -- tablet turns on to show the Lenovo logo, after a few seconds the screen goes black (the device appears to have turned off):
x Power key
x Power Key + Volume Down
x Power Key + Volume Up
x Power Key + Volume Up + Volume Down
** Release of keys is done once Lenovo logo appears
Any ideas?
UPDATE
I went ahead and performed: fastboot flash boot boot.img << the boot.img was the earlier patched magisk image i used to get the rooted working tablet.
After performing the above the tablet turned on and is now showing the Lenovo logo however it does nothing else --- it remains on the logo forever. I am able to get into TWRP recovery. I went ahead and wiped Dalvik, Cache, and Data. Rebooted to System but still it is stuck on the Lenovo Logo.
The device if fully charged.

You could try recovering the tablet with LMSA. See this post. You'll lose all your existing data and setup on the tablet, though.
Not sure what went wrong for you. Do you have a TB-X605F with Snapdragon 450 SOC? The existing TWRP is only for the SDA450. I'm working on one for the M10s with SDA429.

Thanks for the response. Yes mine has the Snapdragon 450. I will investigate the LMSA. Been messing around all day but made no progress -- not even QPST is working out.
