Connect the one end of the USB cable to your computer. Then while holding the menu button on your arc s (the right one) connect the other end of the USB cable on your phone. Keep the button pressed until the LED turning blue

1) Download custom kernel in .img format. Put kernel file in fastboot folder.
2) Turn-off phone.
3) Press and hold "Menu" button, then connect phone to computer through USB cable. (LED will turn to blue color, means in fastboot mode)
4) If you using Windows 7, press and hold "Shift" button and right click mouse on fastboot folder. Select "Open command window here"
5) At command prompt window, key-in "fastboot flash boot C:\fastboot\CUSTOM KERNEL NAME.img", click "enter".
Remark1: If you put fastboot folder at D drive, then change C:\ to D:\
Remark2: example: custom kernel name is Arc_OC.img, then type C:\fastboot\Arc_OC.img
6) It will start flash custom kernel.
7) Reboot phone.
8) Done.

Personally, I've always had problems with fastboot working properly for me (possibly) due to some driver errors, which unfortunately refused to be fixed. So, I've always used flashtools instead, and frankly, it may be more simple for beginners. So, here are the steps if you wish to utilise this method instead.
1) Ensure that you've got the latest version of Flashtool.
2) Download and install the required fastboot drivers by going to your drivers folder in the Flashtools folder and running Flashtool-drivers.exe. You do not need to do this if you already have them.
3) Press and hold the menu button while connecting to the PC through USB. Ensure that the LED light turns, and stays blue for the duration of this process. This signals that the phone is in fastboot mode.
4) Return to the main screen (with the logs) and click on the lightning icon near the top left. This is the mode selector. Select fastboot mode and you'll be taken to a screen that looks like this.

}
5) Click on 'CHECK Current Device Status' and ensure that the log states your device is in fastboot mode.
6) Click on 'Select kernel to Flash' and direct it to the folder where your .img file is stored. Check the logs to know when your flashing is successful, though it should only take a few seconds at most.
And with this, your kernel should be successfully flashed. If it doesn't, then check if you have the right drivers installed, or if you did everything right.

Disclaimer: I am not responsible for any damage that may or may not occur. I do not anticipate any harm, use at your own disclosure.
Ever since the HTC U11 you cannot gain permanent S-Off, it is unknown if this will ever change. Due to this you must relaunch the Sunshine app every time you want to modify your CID. If you follow this guide to a T, you will understand the process and understand the limitations.
Your Sunshine license is tied to your phone's hardware and cannot be transferred to another device.
You cannot change a Dual Sim to a Single Sim device and vice versa.
Whatever new region CID you switch to, you must have a matching MID.
If you ever relock your bootloader, you must revert back to your original CID before doing so.
You may lose or gain WiFi Calling and VoLTE Features depending on the CID. Flashing LeeDroid Magisk Rom will enable the features on any CID. Your Carrier must still support them!
Requirements:
Properly setup ADB and HTC drivers, enable Developers options, USB debugging
Unlock your bootloader, install TWRP and root with latest stable build of magisk.
Use without a phone case to have access to sd card slot and Vol. up button
32GB or less, micro SD card
Good quality USB cable, preferably OEM
Funds to Purchase a license to use the Sunshine app
RUU of the CID you want to change to
Connect your device to your computer and startup the terminal. Use
Code:
adb devices
to see if your device is recognized.
Reboot to download mode by using
Code:
adb reboot download
, you device will reboot in download mode then use
Code:
htc_fastboot getvar all
and note down your device's information.
Once you got your CID and MID information, locate the CID you want to change from this spreadsheet and make sure they having matching MID. Then download the appropriate RUU.
Rename the RUU to 2Q55IMG.zip and place in the root of the 32gb micro SD card.
Visit official sunshine website and download the Sunshine app from the download section. Install the apk, run the compatibility test in sunshine and once confirmed compatible buy a license.
Launch Sunshine and read the instructions, it will send your device in download mode with temporary S-Off.
Connect device to your computer and open the terminal. Use
Code:
fastboot devices
to make sure your device is detected in fastboot.
Use
Code:
fastboot oem writecid
with your desired CID at the end. Do not reboot! Example:
Code:
fastboot oem writecid HTC__626
On your device's Download Mode Menu select Reboot to Download with the Vol. buttons and press power button to initialize. You will now have your desired CID and your device should still say S-Off. Do Not Reboot!
Insert the SD Card and on your device's Download Mode Menu select Reboot to Download with the Vol. buttons and press power button to initialize. Your device will now be prompted to press vol. up to use the RUU on your SD Card.
Your device will erased,formatted and converted your new CID. You are done!!
Setup LeeDroid Magisk Rom to enable Wifi-Calling and VoLTE options.

Thanks for writing this guide up man, I know it's only preliminary at the moment but I'm sure myself and many others will appreciate it.
Once I get home tonight I think I'll be changing my CID so I can finally get my bloody phone on Pie!

Ok I've hit a stumbling block.... S-OFF just fine and manged to change the CID in command line however when I go to type "fastboot reboot download" I get the following error "fastboot: usage: unknown reboot target download"
Luckily I just changed my CID back to my standard one, reset the phone by "fastboot reboot" and away I went again. But still obviously on my stock CID.
So I tried again, this time changed the CID and selected Reboot to Download in the Download mode menu itself and that worked a treat. So here I am now running on my new CID!
Your guide was awesome, thank you. Just thought you might want to amend that little step unless I've done something wrong or am using a different fastboot version thank yourself

Not a problem, thank you for putting the guide together!
Not sure about root yet, I ran out of time but from looking around it seems installing Magisk is a bit different due to TWRP not working properly. Not sure if you want to include that in the guide as well?

I am on latest OxygenOS version that is the only thing that I can say right now :/
One thing -> It is detectable by PC when switched on into that mode or into Recovery mode.
Did anyone here had similar issue? Or maybe you know what at least I should try on my own?
I contacted Oneplus Support already, but it is weekend and I just stuck without phone...
Cheers!

Device Model?

LE2123

hold volume up/down and power. It should reboot

Thanks,
I tried that but nothing changed.
I tried to reboot also from recovery mode but the same result.

Did you save the msm tool? Do you still have the download link? Can you pm them to me?
NVM thought you were OP haha

Did you try keep holding the Power button for approximately 10 seconds, the phone should shutdown. and when completely off, just press Power + Vol Up + Vol Down to boot into fastboot mode. To boot normally just select Start by pressing the power button.

In my previous OnePlus devices, whenever this has happened, I was always able to get out by simply pressing Power +Vol Up+Vol Down all three buttons together to reboot into fastboot, try this combinations as well.

Doesn't apply to his LE2123, that's why I asked for his model to begin

I have fixed my past devices from this issues by following these steps:
1. Download latest firmware from OnePlus (Official Site or XDA Links)
2. Extract the downloaded file and there will be "payload.bin" file that you need to extract by using a payload dumper (you may try this link or this one)
3. Once you have all the images (img ) files to flash the phone you can use this guide for flashing.

All the best!

Nope, didn't showed up.
I've got my remote session to learn that they cannot help, device need to be send to repair.

How to root Your MICROMAX IN1B (64GB)

First of all, before i start, I'll make this clear, i have done this procedure and rooted my IN1B successfully BUT if anything goes wrong with your device,
I WILL NOT BE RESPONSIBLE FOR BRICKED DEVICES
PreRequisites (Stuff you will need)
So, Let's get into it.
Before Begining, Here are the things you'll need :-
1. A windows PC with all the necessary drivers.
2. ADB and fastboot which you can get from here.
3. A USB C cable, preferably the original one.
4. Make sure your Device is atleast 60% charged.
5. Backup all your data because the very first step will reset your phone.
NOTE- MICROMAX DOES NOT PROVIDE ANY USB DRIVERS. So i had trouble finding the Drivers too, so i recomend you use "Driver booster" it's free, you can get it from here. After installing the driver booster, let it scan and then update all the drivers related to "Android" and "ADB".
That's it, once you are done with all the above points we are good to start.
These are the PATCHED files you need to flash to root your device.
1. Get the files from Here
After you download the files, copy and paste the files in the folder where ADB & Fastboot is located, if you have not changed the Install location, it should be at this directory- C:\Program Files (x86)\Minimal ADB and Fastboot
After you paste all the 3 downloaded files in the ADB folder, the process will now start.
Unlocking the BootLoader
The first step is to unlock the boot loader.
1. Connect your device with a USB C cable.
2. Enable USB debugging from the developer options-
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
3. Now run ADB and run this command- adb devices As you run this, something like this should appear on your mobile-
4. Now allow it and Voila!, you are now connected!
5. Now find "OEM Unlocking" and enable it.
6. Now enter this command- adb reboot bootloader As you run this command your device will reboot and show a black screen with only "fastboot" written on it.
7. Now finally Enter this command- fastboot flashing unlock
8. Now it will ask you to confirm, if you change your mind and dont want to root now, press the "Volume-Down" Button or if you want to root, press the "Volume-Up" button.
NOTE- UNLOCK MAY VOID SOFTARE WARRANTY. FOR DETAILS, CHECK THIS (Read 6e)
9. Awesome! Now you have unlocked your boot loader!!
Flashing the Patched Files
Now remember you need the 3 files i linked above, once you get them, paste them in the ADB folder.
Make sure you DON't change the file names.
Let's Start!
1. Run this command- fastboot flash boot patched_boot.img
2. After that, Run this- fastboot --disable-verification flash vbmeta vbmeta.img
3 And he final command, run this- fastboot flash recovery recovery.img
After all these 3 complete succesfully, Just run- fastboot reboot This will start your device normally, go on and set up your device.
1.As you complete the setup, you should see the magisk app-
2. Now the magisk app will ask you to install the full version, click on confirm and it will install the magisk app, you will have to turn on the "Unknown sources" option.
3. Once it is installed, you can ENJOY YOUR ROOTED IN 1B!!

FP4 stucks after unlock the bootloader

Hello together,
today i tried to install /e/ OS on my new FP4.
I did everything like in the official description:
> ## Unlocking the bootloader
>
> 1. Boot the device
> 2. Enable and connect Wifi
> 3. Enable Developer options
> 4. From developer options, enable OEM unlock
> * Get the unlock code from [this site](https://www.fairphone.com/en/bootloader-unlocking-code-for-fairphone-3/) and enter it
> 5. Reboot on fastboot by running the command in the PC console `adb reboot bootloader`
>
> 6.*Tip:** All the console commands are run on an adb enabled PC and in the `adb` console.
>
> 7. Ask for unlock with `fastboot flashing unlock`
> 8. Approve with <kbd>volume +</kbd> then <kbd>power</kbd>
> * The device proceed with a factory reset, and automatically reboots
At 8 i maybe made a mistake, when you are in the fastboot mode, you can choose different options, i choosed something like FFBM or something like this. Then the device restarted and since that it always shows the "blue dots" like in the beginning but nothing more happens, since hours.
I turned it off and on again, without success.
I can not load the fastboot again via ADB, because the device is not recognized.
If i try to use the volumeUP or VolumeDOWN at the startup, nothing happens and it restarts again after a few seconds.
So there is no way for me to enter the fastboot mode again.
So I have two questions to you, lovely community.
One is, can anybody help me?
Second, can somebody tell me how the different options are called in the fastboot mode, so i can google it and do more research.
THANKS a lot and sorry for my english :slight_sm

Hi,
Are you able to launch the stock rom or are u stuck on bootloop or bootloader page ?
If you can launch the stock rom, enable oem, debugging and unlock bootloader in developper options.
Then connect phone to pc with the cable and type adb devices
see if the phone is recopgnized.
Then adb reboot bootloader and do all steps of the official guide.
If you use Windows I suggest you to put all file to your adb folder, type CD /path/to/folder/
And copy paste all commands at once, this will avoid error of mishandling during fastboot operations.
If you stuck on a "waiting for phone" when you are in fastboot mode, check you driver, or test with a linux machine or see Hulk's solution here
If you stuck on a bootloop just use the key combo to enter bootloader. check on the bootloader is everything is ok (unlock) if not redone steps to unlock bootloader, then flash recovery from /e/ os folder fastboot flash recovery recovery.img
Then enter in recovery use the combo key to have the menu choice between bootloader, recovery... then enter recovery and wipe data...
Then restart the official guide of /e/ os.
You may ask on /e/ os forum too many much more Fairphone user are there and can help you (link i gave you above).

Hello,
thanks for your reply.
I posted the same comment at the /E/ OS Forum as well.
I Can not load the stock rom, there are only this blue dots circling around for hours:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I can not enter anything else, using ADB is not possible because the device is not recognized and the combination of volumeUP and power or volumeDOWN and power only restarts the device.
Do you have a FP4 and you maybe can tell me which options in the top of the fastboot menu you can choose?
Something like reboot and so on.
I will try the solution in your link in a few hours when i have more time.
Thanks a lot and BR

Bootloader menu options are "start / restart bootloader / recovery mode / power off / boot in ffbm / boot to qmmi"
I don't understand your problem if your bootloader is unlock you must have accesss to bootloader.
Are you sure you didn't relock bootloader before checking the rom is correctly installed ?
Contact /e/ support to have the precise combo key to enter bootloader. sometimes it change from phone to phone.
Does your computer works well with adb and fastboot before ? did you already flash rom ? Maybe a driver is missing or adb/fastboot is not on the last version. You may try with a linux pc to aovid those problem.

How to Boot into bootloader mode
This section will be relevant later throughout the guide, when you need to reboot into bootloader mode.
Remove any USB-C cable and turn off your Fairphone 4
Tip: If you cannot turn your device off, remove the battery for about 5 seconds, then put it back in.
Press and hold the Volume Down button.
Insert a USB-C cable connected to the power (can either be a power outlet or a computer).
Release the Volume Down button as soon you boot into bootloader mode
For more details on how to erase the data on your FP4 refer this guide
I just try this and works great : power off the phone (if you can't just remove battery as said), press vol down and plug the usb cable
My phone has the bootloader locked and flashing locked and it works. try this

You are my hero.
I dont know how many times i read that but i was to stupid to do that correctly.
Now i tried it again and it worked well!
Thanks a lot!
Problem solved.
Just for other idiots like me, i choosed the option boot into ffbm into the bootloader menu, this was my mistake.
