[Q] P3100 Unlock Bootloader, FastBoot, Modes

I apologize if I have understood this all incorrectly, but kindly clarify the following for me.
What I have already done:
1. Installed CWM (ClockWorkMod) on the tablet: Galaxy Tab 2 7.0 using Odin
2. Installed the rooting zip file from external sd
3. Made a backup image on an external sd
What I need to do:
1. Flash a custom ROM onto the device from my PC using fastboot
Errors:
1. Fastboot devices returns nothing (absolutely no response... please find the attached pic)
2. Adb reboot bootloader - just reboots the OS (not in fastboot)
3. Fastboot oem unlock says waiting for device endlessly.
My Queries:
1.I have a recovery mode and download mode (aka odin mode). Is either of them the FASTBOOT mode or is fastboot something completely different. If so how to get into FASTBOOT mode??
I read I have to get a USB icon and a Fastboot mode display on screen. I do not.
2. Why is my device not showing under fastboot devices (on download mode, neither show the device.), but adb devices shows the device under recovery mode
3. Is it possible to flash a ROM using fastboot if I have CWM installed. Or does CWM disable fastboot?
4. Also does this device have a Fastboot mode at all? If yes how to get into Fastboot mode??

From what I've read here, there is no fastboot mode on the Tabs.

load it on your external sdcard, boot into cwm and do a fullwipe/factory reset then install the zip from sdcard. poof, rom installed
to boot into cwm, turn off the tablet.
press and hold power and volume down (the one closes to power button) once the samsung tablet logo appears let go of power and continue holding vol down until cwm appears (this can take a couple minutes)

Thanks then!

[Completed] [Q] Install a ROM without fast boot menu

Hello everyone , I have a problem with myHTC ONE M8 (Chinese version) . I try to install a new ROM, but in following the instructions to flash the phone. I do not have a fast boot menu by pressing the power button and volume down.
So my question : is it possible to install a rom without the fast boot menu ?
Thank you in advance

Hi,
Being the Chinese version the button combo may be different, try a few other combinations
Or to get into fastboot just use adb, turn on debugging and open a terminal on PC and type
adb reboot bootloader
Here is a guide that can help you set up adb and fastboot

Hi there. Since you cannot flash a custom recovery cause your bootloader is locked and a bootloader unlock will erase the data you want to get, the only option is extract the info from fastboot mode.
You must boot the phone in fastboot mode (power and vol- for 3 seconds), install motorola drivers and download mfastboot tool. In fastboot mode you can use some commands to extract info, here you have the list of commands you can use and here is a tool that can ease the job of writing every command.
Look in the forum FAQs, help about mfasboot and drivers is there.

thanks for ur answer moralesnery
but its seem that i need usb debuggin, otherwise adb dosent find the device.
can allow usb debugg?
i tried in my other phone, and witht usb debugg it work just fine!
it seems that adb only work with the phone in normal status
when someone has bootloop it's constantly restart and the process will not work
fastboot works, but its seems that i cant pull thing with the fastboot menu.

Try this:
1. Boot to bootloader
2. Unlock the bootloader
3. Flash ClockworkModRecovery
4. Boot to recovery
5. Go to mounts and storage (press vol - many times, when that option is highlighted, press power)
6. Now go to mount /sdcard (press vol - many times, when that option is highlighted press popowe
7. Plug the cable from your phone to the computer. So now your PC will detect a device. And you can copy files from your phone to the PC)
Hope that this works for you, sorry for bad english.

How To Open Recovery On 10.or Device|All 10.or Devices|Guide

Hi Friends​In this post i will tell how you can open recovery mode in all 10.or Devices. I have 2 methods to do this.
So Let's get start
Method 1 - Using Pc
Requirements - 1 Usb Cable and PC
First You Need To Install Adb Drivers On your PC and Download Platform Tools zip file for Windows PC by Clicking This Linkhttps://developer.android.com/studio/releases/platform-tools.html. Now Extract File and Open platform tools Folder and Press Shift Key then Right Click. Now You Will See Open PowerShell window here, Click It.
Open Your Phones settings and go to about Phone. Click Build Number 7 and more Times it will Open Developer Option. Now open Developer Option And turn On Usb Debugging.
After Opening enabling Debugging Connect your Phone Using Usb Cable.
Now Run Commands
"Adb Devices"
Your Device Prompt For Debugging. Grant It.
If Your Device Appear In PC Run Next Command
"Adb reboot recovery"
Now your phone automatically boot into recovery mode.
Method 2 - Without PC
Requirements - Only Your Device
Simply Turn Off Your Device. After Turn Off your device Press Volume Up key Then Power On Key. After Vibration release all keys.
It will boot Recovery Mode
Now You Can Wipe, Install Update, and Unlock Bootloader of your 10.or Devices.
This Is A Hint To Increase Development Support For This Devices. So Developers Try To Unlock Bootloader And Start Making Roms and recovery etc. After Any Rom or recovery Roll Out for this device I will Root My Device and Just Install It on my device.
Thanks

Z3 Won't start or enter recovery

Guys,
I need help. I'm struggling for the last 3 days trying to revive my phone with no sucess. :crying::crying::crying:
I managed to put a custom rom sucessfully, but i had to make a restore on recovery mode.
During the restore process some error ocurred, something like "something not mounted", i did'nt have the ROM to flash anymore. For no reason i decied do reboot the phone.
Now i can't enter recovery anymore and the phone is froze on the "Sony Xperia" on the begginig.
Since start i'm having difficulty with the Z3 driver for Windows 10. To enter recovery mode i tryed to adb reboot recover but my adb doesn't work.
It's strange..
if i type fastboot devices it's show.
if i type adb devices it's show's "no emulators/xxx found".
I need help, don't know what to do anymore.
TLDR:
- Frozen at "Sony Xperia"
- Recovery don't enter pressing Volume Down/UP
- adb devices doesnt' work.
- fastboot devices work
Thank you!

You have some choices to restor stock rom:
1) Try Xperia compagnon fron Sony ==> Software repair (not shure about the label in english version)
2) Use flashtool (google for it) and a rom (*.ftf) of your choice.
When you are back to stock, then you can install a custom rom again

Hey,
Sounds like a corrupted system, not too sure what happened with the recovery though.
Try this out:
1. You need the phone driver and the fastboot & ADB driver. You can get the Sony phone drivers from the Xperia PC Companion. You can get fastboot & adb drivers almost anywhere, just google for them or scroll a bit through xda.
2. Unlock your bootloader if you haven't done so already here.
3. boot into fastboot mode by completely powering off the phone then holding "power+volume up" and waiting until a blue LED appears in the top left.
4. Find a custom recovery, rename it to recovery.img, navigate to the folder that contains it in CMD (i.e. cd C:\Users\USERNAME\Downloads\Android) and type "Fastboot flash recovery recovery.img"
5.You should now be able to boot into recovery again. All that's left is find a ROM of your liking, push it to the phone in ADB and install it.
Hope this helps!
