i have the same problem,i get to purple screen try toreplace the custom recovery.img,but i restart the phone is restore original recovery.img
I also had this problem with my friends tablet, It was an alcatel tablet, I was able to access recovery mode and I wiped data but nothing happened. My friend found a hole at the back of the tablet and inserted a push pin and there it is it was wiped! Maybe there's something like a button in your device to factory reset it?

[Request] Tips to save a phone that restarts itself

Hi all, my question prescinds from a phone particular model. The problem is that for some sort of software issue, the phone restarts itself after few seconds that rom unlock appear. I'm sure that is a sw issue because in recovery mode it stays alive and when he does the application update after a dalvik cache wipe, all goes well too!
It's not possible to enable usb debug because it restarts too soon and in recovery (cwm) it's not possible to connect via adb. It's not a rooted phone. Also in safe mode it stucks in bootloop
What i can do before a factory reset?

Looks like its bootlooping ... Yes its a software issue ... I don't think u have any option other than factory reset ... Take a backup first before u do that...or perhaps u can use a logcat if u know what it is
i will try to take backup in sd card and retrieve some useful data from this.
how can i use logcat if can't connect through adb?

I tried Simple factory reset and it just restarts,
My wifi will not switch on.
Can someone please tell me the simplist way to do a full factory reset on this device, i can access the internet using my cellular network.
Many thanks

Can you use Flash Tool? I mean my computer does not recognise my P9000 but when I turn the device off, prepare Flash Tool, connect the USB cable and turn the device on it works.
I think that should be the most easy way to perform factory reset/flash the stock ROM.

I dont have the device yet but im thinking you could factory reset going to fastboot and doing fastboot erase userdata, no recovery mode needed and should most certainly work

[HELP] BootLoop Issue

First of all, I don't know where to post this thread. Please redirect me if this thread is not for here thanks.
Hi, Im having serious problem with my Samsung S7 phone. what happen was I was trying to install root on my phone, but my TWRP cant find my Internal storage. so I try to search on youtube how. then I saw repairing/formatting the data to exFat/ext4 or something. I did the steps but it shows error while formatting the data and its still on formatting process so there is no any back buttons or anything to cancel it. It take like 10mins on formatting process that keep showing errors so I did turn off my phone.
After that I turned on my phone. TWRP logo shows up and it stays there. It wont go to the main menu of twrp. I cant even turn off my phone after that. if I do the volume down + power, it will just reset to twrp logo. I cant make it turn off so I can go to download mode or safe mode to factory reset coz it doesnt accept any buttons except if I reset the phone [by pressing volume down+power] which directs me to TWRP logo.
Only way to completely turn off is to drain the battery. If I charge it, it automatically opens and lead to the TWRP logo again at get stuck.

Moto E 2nd Gen Data Recovery

I have a stock Moto E 2nd gen from AT&T which has lasted for years, I actually loved this phone even with its limited space.
Anyways, my phone now boots and gets to the motorola logo, then the AT&T logo, then black screen! I should note that while the screen is black I can hold down the power button and it shows the "Power off" popup. There's no back or home buttons at the bottom of the screen.
I've tried wiping the cache and booting into factory mode with no luck. I can't seem to get the device recognized via USB while booted or in recovery mode. Also, as it's an AT&T phone the bootloader is not unlockable.
So the question is, is there anyway I can pull the data off the phone or possibly fix it? O'm thinking my only option is to try flashing a stock rom from the external SD card from the blooader without wiping the factory settings to see if that fixes the problem. Really, I only need to salvage my data so any way I can get into it would be great.
Does anyone have any ideas or has had a similar problem and managed to salvage their data?
Any help would be greatly appreciated!
bump!
