Hello,
My p780 has been stuck in a boot loop and I cannot get past the logo. I can only go into the stock recovery (3e) mode and try the options there, otherwise the phone will be never get past the Lenovo logo screen, where it says "powered by android".
It seems there are some modified custom recoveries that are based on CWM and TWRP. Is it possible to flash a working one from either SD card or ADB sideload?
many thanks.
Can you go to the screen(Pressing power+vol down) wherein you can select the options like normal boot,recovery etc?if so,you can flash a custom recovery or else google and see how to enable fastboot menu for your phone. Then you can install custom recovery.

Hi,
I'm trying to root and install CWM recovery on samsung i8558 Galaxy Win (China Mobile version).
I have at hand a set of stock firmware, a pre-rooted boot.img, and a cwm recovery image (6.0.3.7) built from cyanogenmod source only with recovery.fstab replaced with the one extracted from stock recovery.
Also I've tried ROM Manager, but it won't boot into recovery after claiming to have installed CWM.
I have successfully rooted the device using the prerooted boot.img.
The problem is that when I flash my custom cwm recovery onto the phone, it won't boot into recovery by normal means (holding home, vol+, power). I can only enter recovery via 'adb reboot recovery'. Unfortunately it leaves me stuck in recovery mode, 'reboot system now' fails, 'adb reboot' fails, the only way out I've found is flashing stock recovery.
I guess my cwm image is not properly configured to suit my device. I have tried the Recovery Builder at builder.clockworkmod.com, but its output is totally out of function - black screen without anything.
Any clues?
Which CWM did you use?
I'm using i8552 with many custom Rom and finally a swipe cwm. Which cwm did you use to flash?
Also if you are on JB 4.2.2 will you send me a snap shot of your settings page, notification bar and About page?

Hi all,
I have successfully rooted and installed CM12 on my Motorola Moto G 4G. I was unable to get into recovery so I download ROM manager to boot into recovery and thats how I installed CM12.
CM12 is stuck in a boot loop so I want to install CM11 or go back to Stock but I cannot get into recovery now. If I boot up with power and vol down I am taken to a fastboot screen which has an option to goto recovery (second option down) but this simply boots back into the device.
I was using CMW but I installed TWRP and now this simply takes me to a blank screen (or it could be powered off).
Can anybody advise how I can boot into recovery? (I am still able to use fastboot commands).
Thanks!
Just find a working recovery image and flash it (TWRP 2.7.1 works for me), also make sure you are using the right controls in the fastboot menu, they're tricky
Use fastboot to reflash recovery. After a successful flash, use the button combo on the fastboot screen to boot into recovery.
XDA,
I am trying to root the stock rom (Cyanogen OS 12.10YOG4PAS1N0). I have thus far managed to unlock the bootloader and am now trying to install a custom recovery - here I run into some problems:
So I downloaded the latest TWRP and renamed it recovery.img - pressed 'fastboot erase recovery' and then 'fastboot flash recovery recovery.img' -all going fine.
I then unhook the phone, turn it off - press volume down and the power button to boot straight into recovery (not even booting OS) and here's where it gets interesting:
The 1+ logo appears, as if its trying to boot recovery - it hangs for 10s, then the screen goes black and it vibrates. The 1+ logo appears again and it boots straight into OS.
If I keep pressing volume down I am in a loop like this, with 1+ logo, screen black and so on.
So I never actually get into the custom recovery. And if I boot into the OS and press restart into recovery: I get stock recovery.
I've tried CWM. TWRP, Philz, the toolkit, manually - lots of things. I turned off overwrite custom recovery in the developer options - all to no avail.
I hope someone recognizes this problem and can help me out.
Thanks a million,
Michiel.
Not sure if this is your issue, but go to this thread on how to unlock bootloader, install custom recovery and root. See the note in underline at the bottom of item #2, installing the custom recovery. I was unable to get TWRP to stick until I followed this simple method.
Yes, I tried this but when I power the phone down and boot it with the powerbutton and volume button - it hangs on the OPO logo and reboots again into the OS.
I flashed TWRP on my tecno W3 using sp flash tool, after it went successfully, i powered my phone into recovery mode with the right combination of keys. But it wont boot into anything, but when i power it into normal mode, it goes successfully..and then i switch off and boot into recovery mode with the same combination of keys i used after flashing, it end up into stock recovery. It's like my phone is locked from booting into custom recoveries(even after unlocking the bootloader), and then it overwrites the custom recovery with stock after booting into normal mode. Is there any way i can get my phone to accept custom recoveries, and i have no root thats why im trying to flash a custom recovery first.
Also: I tried to use adb to boot into fastboot mode and boot into the same custom recovery i have by the command: fastboot boot <filename.img here>..but i didnt boot into anything, it just boot normally like i restarted my phone. I even tried to flash the img file in fastboot mode and then boot up with the fastboot command mentioned above, but it just boots into normal mode.

Did you install SU/Magisk after you flashed TWRP?This can usually prevent this issue.

No, just TWRP. It flashed successfully, but the phone won't boot to anything, and when i force it to boot into recovery mode after flashing a custom recovery, it doesn't do anything, it just stucks in the Hi logo with a red exclamation mark...and i usually have to press the volume + and power button to get to the menu, but the menu for the custom recovery i just flashed fails to pop up. After that, i boot into normal, and it overwrites the custom with stock recovery again (can tell from when i boot into recovery again after booting into normal by bringing up stock recovery)..
I used the recovery i ported myself using calvik image kitchen tool.
My phone does it too. The TWRP asks me if it has to be reinstalled, if default recovery is taking its place. Flash SU or magisk in your recovery immediately after TWRP.
twrp installed successful ...
after that if am trying to go to recovery ...it will open stock recovery (comes with phone)
please solve my problem ..

When you flash TWRP, after it flashes, you then have to boot into recovery before you boot to any of your device's other modes, if you allow the device to boot into any other mode BEFORE booting to recovery, it will revert back to stock recovery. The very next thing you have to do after flashing TWRP is to boot immediately into recovery before you do anything else, then it will keep TWRP recovery.
Flash the TWRP recovery via fastboot, then type the command:
adb reboot recovery
Or
Flash TWRP via fastboot then disconnect the device and power the device off, then press and hold the correct button combination to boot into recovery.
