Worked on my Lobster which was hanging on windows startup screen.
WITH PHONE SWITCHED OFF
1. Press and hold soft1 and soft2 keys (i.e. menu keys).
2. Press and hold power button for around 1 to 1.5 seconds. Release power button. Keep holding both soft keys.
3. After a while, black screen should show instructions asking user to press '0' key to reset to factory default.
4. Press '0' within the timeout period (which is very brief).
5. If instructions don't appear on the screen, repeat steps 1 to 4.
After tinkering around with the developer settings i came to the conclusion that this device soft bricks when you experiment with the ART compiler, lets just say enabling it will keep you at the boot screen. I used this method on other Padfone Variants and it works on the Padfone X
If you are on the ATT boot screen and nothing is going on dont catch a heart attack
1) Hold the Volume - button on the side of the device and hold power till the phone reboots, keep holding the Vol -
2) You will be greeted with a prompt to enter or exit recovery, of course choose the enter recovery selection with the volume keys and hit power to enter
3) You are greeted with a selection screen anything from installing firmware from the phone or external sd and of course the ability to Wipe / Factory reset
4) Navigate with the vol - key to highlight Wipe / Factory Reset and hit the power key to enter, then on the next selection screen navigate down to perform the action
process takes about 4 minutes tops, afterwords the screen will pop back into the main selection screen, choose reboot phone and wait. As with all first boots this will take about 5 minutes tops, hence the ATT Logo will be visible, you will then jump into the get started screen as you did when you first bought the device.
Hope this helps with those experiencing problems
Try not to remove any bloat/or features if there is no official firmware recovery, you run a huge risk in perma-bricking your device if not careful. Wait for the DEVs to swarm in and serenade us with features
And BTW...stay away from selecting the ART compiler if youre going to enable developer mode, Stick with Dalvik if you dont want to get stuck.
1.- Wait until the device turns off.
2.- Plug the device on the base and when the screens shows the battery logo, unlink the device form the base and immediately press and hold the power button.
3.- When the ''rebooting'' screen apears, relase and press twice the button again to enter the menu.
4.- Go down to the options and select download (1 Click: go down, 2 Clicks select).
5.- Conect the device to the computer, open odin, and flash the tizen rom. (E-mail me for the link).
6.- Wait until the process finish and never try to flash another thing to your watch.
Hope you can revive the watch .

My cell phone model is Huawei Y536A1. It suddenly turned on by itself for several times and then finally my phone screen just stayed on the "android". I tried several ways to deal with the problem, but sill could not work.
I tried ...
1. Alternate Master Reset Method: a) press and hold the Volume Up and the Power key for 8 seconds, then release b) Press the Volume down key until "wipe data/factory reset" is highlighted c) Press the Power key to select > Press the Volume down key until "Yes -- delete all user data" is highlighted d) Press the Power key to select e) Once data has been wiped, a green "OK!" with a checkmark will be displayed f) With "reboot system now" highlighted, press the Power key to select.
--> it did not work for my phone.
2. I also tried "wipe cache partition". It still did not work. It went back to the logo "android" again.
3. I went to AT&T store. They could not help because of out of the warranty. A staff even did not want to try. It's very frustrating. Later, I asked them to change my sim card to my traditional old AT&T phone. So, my Huawei Y536A1 is no sim card now. However, i still want to use it if it can work.
After I took out of the sim card, my phone screen will stay a global sign for a while and then turn of by itself. ><
I would very appreciate if anyone could give me possible suggestions to fix that problem.
Thank you.
Summary - After two weeks of research (mostly on XDA) I took the risk and decided to root my new Samsung M30. Suffice to say I was extremely apprehensive given numerous reports of bootloops, recurring seven day OEM device locks, crashes, hangs and general instability. After following specific steps that combine several sources, I successfully rooted my device. Moreover, key root applications are all working well (AFWall+ Firewall, AdAway, Root Explorer)! This guide shows what I did.
