As long as a phone powers on it's NOT hardbricked, but softbricked if Android doesn't get properly started.

even if it is soft bricked i am not able to get into recovery mode this was showing:

Re-flash phone's STOCK ROM.

damn, i am not able to get into fastboot dude that's what it is all about if i would be able to get into fastboot i would have flashed my phone long time ago.when i ty to get into fastboot android sign with yellow helmet appears.
My zenfone 4 problems:
access to droidboot or recovery (stuck at android icon with a yellow helmet), so i cant flash a rom or firmware.
Tried different combo keys, but always stuck with that android icon.

You typically re-flash a STOCK ROM by means of ADB Sideload method.

ook so for using adb sideload method u need to get into droid boot what i am saying it i am not able to get into droid boot mode and everytime i try an android sign with yellow helmet appears.

You are absolutely WRONG.
What you have to do is running ADB commands as follow
Code:
adb devices
adb reboot sideload
adb sideload <FULL_PATH_TO_STOCK_ROM_ZIP_FILE_ON_PC_HERE>

i am noob please can u tell me the steps elaborately OKAY,
NOW I HAVE GOT IT BUT IS NOT SOWING ANY DEVIICES I HAVE CONNECTED MY MOBILE SEE:

Then you obviously never have enabled USB Debugging on phone what is prerequisite to run ADB commands.

[Q] Help with my Android Phone

About the phone:
1. I dont know the exact phone model, but it is Cloudfone Ice plus. There is a phone called Cloudefone Ice (Huwawei u8500) but i dont know if mine has another name.
2. It looks like this,
h++p://cdn2.sulitstatic.com/images/2012/0926/222830332_22162996997ba02ceb979675b8093b33516b3b725d6504ce0.jpg
3. Adroid version 2.2.1
4. Detected as "Globe Phone" in Google Play Market. *Globe is a carrier in our country.
The Problem:
When I turn it on, the android logo appears, and stays like that forever.
Cause:
After I tried to install a custom ROM using update.zip in recovery mode, the process got aborted in the last part of the installation.
5. I'm not sure if it's fully rooted, I have superuser but when I tried Root Checker before, it's not.
Other info,
I already tried to boot in recovery mode(it's the only mode that I get into now), I wiped data and cache/factory reset.(still stuck on boot screen)
I tried to install other Roms(update.zip), but all gets aborted in the beginning
I tried to download an update.app file in a dload folder in the root of sd card(firmware for huwawei)- I can't go to update firmware.I can only go to recovery mode.
I tried adb, I can use adb devices, it shows MT(serial number)
adb shell shows adb shell exec '/system/bin/sh' failed: no such file or directory exists
superboot cant detect the device.
I boot the device using power button+volume up,
when I use power+volume down, android logo appears and "Factory Mode" in the lower left (then It stays there forever, whatever button i press)
These are the infos that I can give, please help, I'm looking for fixes since yesterday from google and forums but no luck, nothing works so I decided to post my own.

Having issues with OPO adb

Hello everybody
Well, I have his issue. I tried to flash some new roms into the OPO yesterday and I had some issues with one, so I decided to flash other one, but when I wiped the things I also wiped the internal storage and I didnt know that that would erase my OS, now i'm trying to flash a rom but it wont let me with the bootloader because it says its locked, and if i try to unlock it using OPO toolking via ADB sideload the phone shows it requires ADB 1.0.32 which is the same that i have installed on my computer and if I try it using the bootloader option it just restarts and it keeps being locked. If I try to send a rom with the CMD on my pc it says "error: closed"
I have done some research and found some similar cases but not simiilar enough to have the same fixes
I have windows 10 and TWRP is 2.8.7.0
If anybody helps me that would be pretty useful
Thanks!

SOLUTIONS THAT MIGHT WORK
1) Use Fastboot instead of Sideload
Cmd
Go to Fastboot folder with CD
Boot into Fastboot , then type fastboot devices.
If you see the Oneplus One, then just download a random ROM and FLASH the ZIP

Tablet bootloader broken! PLEASE HELP!

Hello guys, last week I installed the unofficial port of MM from here http://forum.xda-developers.com/shield-tablet/general/unofficial-update-original-shield-t3281541 and everything was going well until yesterday the screen got frozen. I tried to reboot the tablet but It got frozen in the nvidia boot logo, so I tried to reinstall the ROM through fastboot. This step is when I realized that I cant write sometimes through fastboot. I can go into this mode but sometimes the writing failed until now everytime it fail. This is the error reported on the screen:
writing 'boot' ...
FAILED (remote: (FileWriteFailed)
This is a screen capture of the command window:

"lightbox_next": "Next",
"lightbox_previous": "Previous",

}
I think that I have broken the bootloader but I cant find the bootloader img for the tablet. Any help will be thanked!
If fastboot is working you still have a working bootloader. You are in fact in the bootloader. I'm not sure why fastboot write would fail. Perhaps the Windows fastboot driver should be reinstalled.
The bootloader is flashed by a "blob" file and is included with restoration images. If the bootloader does get damaged somehow, you can only boot to APX mode and only Nvidia can repair that.
Try do download and use minimal ADB.
Also reinstall the fastboot driver on your PC (deleting tablet from control panel/system/.... and connecting it again and istall again the driver you download from nvidia site or here on XDA)
best thing you can do if fastboot commadn don't work (happen to me) is download a recovery imagere (again nvidia developer site or here on XDA) and use the flashall.bat.
Magic done for me
and u can use it when u have only Apx? .... i cant find driver for it ... i have only black screen alltime
helllo ..! but still the above case wil work for the deactivated shield's..? my sheilds are now in apx mode..
Sent from my SHIELD Tablet using xda premium
If you can only boot APX mode you are stuck. There's no driver for APX mode so you can't do anything with it. Only NVidia can repair it at that point.
I don't know if this may be important but two days before this happened I encrypted the tablet. this may be affect the bootloader? The tablet is still unusable since I can't flash anything thought fastboot starts.

MT7-L09: Phone Unlocked BUT command not allowed when flashing

Hi,
I never saw this problem
My phone is unlocked (since a year more or less) and I can't install TWRP nor CWM. I tried many tutorials such as all the root methods listed on XDA for this smartphone.

There might be a problem with your drivers. You can try uninstalling and reinstalling them. Also, try using fastboot commands manually
Sent from my Mate
unlock again
Thank you. I'd like not to have to relock it as it's already done and rooted. Could you please tell me what drivers to install? I tested many of them (https://i.imgur.com/wBgsezr.png) but it seems I don't have the right ones then.
I'm using Win7 64bits.
Thanks again!
Use adbdriveinstaler and when it's install you can push recovery to add folder and try this command
cd C:/adb
Fastboot flash recovery recovery.img
Change name your twrp or cwm to recovery
Send frome globe
Okay. Here we go
ADB driver installed (https://i.imgur.com/PWrZoHH.png)
Went to flash and... still not allowed.
And in fastboot/rescue mode on my phone it's written PHONE Unlocked.
WTF
BTW, is there any other way to upgrade the phone? Cause every time I go to the software update in the menu i'm told it's up-to-date, but it's not... Android 4.4.2 & EMUI 3.0.
I read about a "local update" but can't find out how to update from the SDcard, I only have OTA.

Do you want to be able to modify your system partition(including rooting the device) at some point in the future? If so, check the box beside the "never show this screen during boot again" then just swipe the slider at the bottom to allow modifications in the future.
Or
If you do not plan to modify your system partition in any kind of way, tap the "keep read only" button.
This happened to me multiple times, for me it was an error with flashing Treble GSI from google, tho i fixed it by going in fastboot mode/bootloader and on my PC to flash boot, lk, lk2, recovery (official one) and then reboot my phone, but you will delete the TWRP Recovery just so you know.

NOTE: I don't know if this will work for you and might brick your device if you don't use correct ROM files...
_________________________________________________________________________________________________________________________
Also if it then boots into Fastboot mode than you can try flashing all files (It will factory reset your phone)
You have to install adb and fastboot on your PC
Commands:
cd *the path to adb and fastboot*
fastboot devices
fastboot flash *what you wanna flash* *filename of the file that you wanna flash*
For Example if you wanna flash boot it will be like ( fastboot flash boot boot.img ) if the filename is with .bin wich most new devices use it will be fastboot flash boot boot.bin
Hope that this helps
