Help on developer mode access - Samsung Galaxy S9+ Questions & Answers

Hello,
I need to flash a twrp or any recovery through Odin. However my phone does not have his developer mode on. I am also unable to log into the phone now. My previous rom is faulty and I turned the developer mode off.
How else can I flash it without a developer mode?
Please help.
Regards,
Ian

Put the phone in download mode and try that way or use samsung switch on a computer to return to stock

To start with, read the rules of this forum and ask question in the right forum.

Zte nubia z5

HI
I have unfortunately flashed a rom from another phone (ZTE NUBIA Z5 mini), now my screen is black, but I can hear that the phone is working; sound when turn on/off phone and sound when I adjust sound level. I have tried to use fastboot mode, but phone will not boot into fastboot, only into ADB mode where my device are listed. Due to my “ROM” fault, USB debugging mode is not turned on, so many of the tools I have tried does not work. Is the phone totally bricked or is there some possibilities that I can try?? Help will be much appreciated.
ROM is root, when I did a test with ONECLICK root, tools tells me that phone is root, so something are working just not my screen.
PS I cant remove battery, it is built into the phone

UPDATE: HELP PLEASE
By a luck I was able to install a new ROM "ZTE-nubia-Z5-cm-10.2-20140115-" but be course I didn't have any picture on the screen I may have touch the phone, because the rom is booting up, but don't work probably due to uncompleted install. Now I have picture on the screen, I can go to recovery and bootloader mode, but still no picture on the screen in these 2 modes. I can use adb but not fastboot maybe driver issue, I have tried nearly every driver on the internet including SDK manager tool.
So is there any change that I can flash via adb mode?

[Q] Coolpad F2 (8675-W00) BRICKED? Image Signature Verify Fail

Hello everyone,
First time here and completely lost with my Coolpad F2.
Tried to flash recovery this way it is described here:
movilesdualsim.com_tema_coolpad-f2-cambiar-recovery-cmw.88858
sorry, cannot put the link to the outside page yet
but after restarting the phone I got the message:
Image signature verify fail
and the start-up logo of the F2. Pretty much this is it, the phone turns off. I can't get into the recovery either as it shows the same message each time I want to turn it on. I guess it's bricked somehow and I must have done something wrong with the tutorial.
Does anybody have any idea how do tackle it?
If some more information is needed just let me know - I'm completely new to this and don't exactly feel there can be a cure for that.
thanks.
anyone?
Try to search on needrom http://www.needrom.com/category/coolpad/page/2/ maybe you can find a solution here.
Maybe you already try to write that recovery, can you factory reset from the recovery?
Hello there, here https://www.facebook.com/tw101.rom.factory
you can find the Recovery and the original firmware to unbrick the phone, to put the phone in fastboot:
1. Press Volume UP + Power
2. Insert cable.
Make sure you've the fastboot driver installed in the drivers.
as reported on http://www.movilesdualsim.com/ you must install the right adb drivers PDAnet

Recovery mode for broken screen AND maybe beokwn home button

Hi,
I'm trying to take control of my galaxy s3 which has a broken screen. I saw a windows tool for it, but I need ADB enabled, which was not enabled on this one. So I'm trying to go in recovery mode and follow some instructions I've seen to enable adb. Sadly, it looks like my home button is also broken (I can't go in recovery mode, or the problem maybe that adb.exe does not list it at all). So few questions :
1) When a pure new stock galaxy s3, when the first screen appears after booting up, does the home button triggers some vibrations? (If no, I'll be sure it's broken)
2) Is there any way to directly flash my S3 with a custom firmware that have adb enabled by default in its properties, without going through recovery mode?
Thanks in advance!

Yes. Theoretically You can flash a custom firmware with odin or heimdall in download mode. Make sure your new rom has enabled adb and debugging and then you can use "adb reboot recovery" and add or remove packages.
BUT, unless you can cook you own room with that enabled, i dont think you will find a room adb and debug enabled by default.
Alternative:
Flash the param zone. After it flashes it will boot into recovery mode. Or try flashing CSC file (just the cache is enough) which does the same.
Edit:
I assumed u know how to go into download (fastboot) mode even though u cant boot into recovery mode. For fastboot is easier, u can google for many tricks. From there u use odin to use Alternative above.

Phone stuck in boot loop - Need to turn on USB debugging

I am currently in a situation where USB debugging was not enabled, CROM service status is set to "Locked". This is causing an issue on my International Galaxy S6 Edge (g9250) -- It is stuck in a boot loop and the android OS that was previously installed was wiped on accident through the stock android recovery mode.
I am unable to flash TWRP recovery to the phone, I am unable to use Odin to flash a stock ROM image to the phone, or perform any data transfer between my Windows machine to the phone. Smart Switch also does not work. Also Now I am sure this is because I never enabled developer mode and turned on USB debugging, and also because this CROM service is set to lock. When I attempt to sideload using ADB I get error:closed. When using the Skipsoft Unified Android Toolkit any task performed stops at: "Waiting for USB debugging".
Is there any solution for this? I've looked all over the internet and haven't been able to solve my issue -- I'm stuck at a perpetual boot loop because there is no Android OS on the device's partition, and also am unable to flash the stock ROM using ODIN or sideload using ADB.
Is there is a way to turn on USB debugging when stuck in a bootloop? Or a way to disable CROM service on the phone to be able to flash or transfer files?
As of right now the device is completely useless and I have been researching for the past 5 days
Any help is very appreciated, please let know if there is more information needed.
Hi there. I am presently stuck in the exactly same situation. Can you please tell me what you did after that. thanks
