[Q] Unable to access Fastboot mode

I read through many threads and have followed the official Sony bootloader unlocking instructions. I have requested and received the unlock code from Sony via email. I have downloaded the inf file and placed it in the correct folder in Android SDK (which I also updated). But I am cannot access fastboot mode, I hold down Vol + and plug in the USB cable but the device shows a red led and goes into charging mode. Also the PC never prompts me to install fastboot driver it simply loads the SP as Sony mass storage device (in device manager).
I have read that some people seem to think that the SIM lock affects the ability to access fastboot but this SP is SIM unlocked. Sony's official guide to unlocking the bootloader says I need to access fastboot mode to enter the unlock code but how can I unlock the bootloader if I can't get into fastboot mode?

hmmm... don't know really... i once entered fastboot mode by mistake, while trying to root stock rom. wasn't reading instructions and put device in a fsatboot mode instead of debugging... was on stock rom so don't know if custom rom would let me do that. should check myself... if anything i know it is possible to get me that blue light shining.

To enter fastboot mode in Xperia SP just power down the phone and hold down the volume up key while pluging your phone into your pc
If you need flashmode do the same thing but with the volume DOWN button held down.

I´ve got the same problem. I can´t enter in flashmode neither in fastboot mode. I´m on windows 8 32bits and I installed the .245 Deodexed ROM with a problem on root and without CWM. I don´t know what to do now, please help me.

As I explained in the first post, I understand how to access fastboot mode (and flash mode). I got root and backed up the TA partition, the stock apps (from 1.257) and backed up the stock ROM. Then, after I wasn't able to get into fastboot, I have installed CWM for LB and flashed a custom ROM based on 2.245. I am able to enter flash mode but not fastboot. As I said before, the phone is SIM unlocked but is acting like it came from a carrier, with locked bootloader and fastboot disabled. How can Sony disable fastboot? I don't get it. Any one want to take a guess how long I will have to wait until some clever dev finds an exploit?

Sorry for that i dont think that it is your computers fault because you enter fastboot (and flashmode) using your mobile phone NOT your PC
So i would roughly assume that this is a Rom bug or something in the flashing proccess went wrong.

Thanks for trying to help, but I understand that flashmode and fastboot are accessed using the phone. Actually the phone needs a piece of software like flashtool to keep it in flashmode otherwise it drops into charging mode. I didn't mention my computer so I don't know where you got that from.
As I explained, I am unable to access fastboot with stock ROM (1.257) and a custom ROM (based on 2.245) so it can't be a ROM bug or the flashing process having gone wrong.

if it's not too much of a trouble for you, go and flash .245 stock, than .257 stock kernel only. like you are trying to root it for the first time, complete rooting procedure, and than proceed on to installing CWM, but instead of connecting device in debugging mode to install CWM, try and see if you can put it in a fastboot. this was exactly the moment when i accidentally put mine SP in fastboot. of course, i'm not saying to go ahead and install anything if you score, but only to confirm if you can put your device into a fastboot mode since installing anything without CWM will likely soft brick your device.

Same problem here, i can't do anything using flashtool after flashed 2.245. I did with SUS, maybe is some flashtool issue.

It may be a flashtool problem you are right because 2 incidents with different Roms that both use flashtool to flash those roms.....
its pretty much self explenatory.

Interesting. Ok, I've read up on the process. So I use the various stock .ftf files and flashtool with the phone in flash mode? Bear in mind that kernel didn't allow fastboot when I used it with the stock .257 ROM the device came with. If I do it, I will nandroid backup first, of course, but I think I remember reading in one thread that someone managed to soft brick their XSP doing this very thing.

Bear in mind that kernel didn't allow fastboot when I used it with the stock .257 ROM the device came with. [/QUOTE said:
that's why you need to complete rooting procedure. root stock 1.257 kernel, than back to stock 2.245 with root preserved, and before you would install CWM try to put device in a fastboot mode, this assuming you still have a UB.

have you tried to boot into android, open a root terminal and type
exec reboot bootloader
that should bring you straight into fastboot

All that happens is that the terminal session ends and closes (not FC) the terminal app. Using the same command via adb just does a standard reboot.

i just placed my in a fastboot mode, no problems whatsoever. do you have drivers for the device installed? you will find these in flashtool installation folder.

Yes. The fastboot_with_android_usb_file.rar package specified on DooMLoRD's bootloader unlocking/relocking appears to have been removed and there are no new links in that thread. So, I found and installed the drivers included with the flashtool. But it seems to be the device that is the problem. It is acting like a carrier locked model. I am rapidly starting to believe that this one has a locked bootloader.

I said before, it's new firmware (maybe RU) with a Windows Flashtool issue. Today i did flash kernel to my SP using Linux client.

Same issues

Hi, I have some similar issues. I've also been flashing some stuff and whenever I try to go to fastboot it just boots into CWM. Very annoying to say the least. The dark blue light goes on when i hold down volume up and for a short moment I see the fastboot driver installing on my computer. But before it completes it's already in CWM.
Not sure what to do from here on wards, maybe some advice on which kernel to flash? I am pretty sure the latest kernel I flashed is the .254 root kernel from doomlord.
Ps. I really would like to flash CM when it becomes available as nightly :angel:
Thanks in advance!

I had already installed cm10.1 jb for my xperia ion.
Now i tried to install cm11 kitkat for my xperia ion.
Every thing is gone good.
But now got stuck up with a problem.
fast boot mode is active only for 5 seconds while connecting my xperia ion to System with flash tool.
help me to do the need ful.
Guide me to download compatible drivers and flash tool for fast booting process.

If you have UNLOCKABLE bootloader, then you dont have a FASTBOOT mode on your phone. Its just pure luck. some phones dont have it... kind of a sony crap... I also happen to be one of those LUCKY ppl. no unlock, so stuck with Stock kernel forever.
When you connect your phone to Flashtools in FLASHMODE...
See for a string BOOTLOADER: NOT_ROOTABLE.... it means you belong in the lucky group...
If it says rootable, then you're doing something wrong.
Pardon me if i read something incorrect. i skimmed through all the posts before posting.

[Q] How to Get Into Fastboot?

Hello,
I'm trying to get back into fastboot mode...my device is a d415, and I have already successfully installed a custom recovery and a custom ROM. However, I want to get back into fastboot mode and I can't figure out how. I zeroed out my laf partition again thinking that would do the trick - but anything I try either boots me into recovery mode or just turns the phone on like normal. Any suggestions for how to get into fastboot? Preferably a way where I can still get into Download mode/recovery mode?

This requires a PC and USB cable. Power off the device. Attach USB to PC. While holding Volume Up attach USB cable to your device and continue to hold Volume Up button until you see "DOWNLOAD MODE" on the second line of the display.

Need help to relock the Razer Phone 2 bootloader.

Hi, Im kinda new to this bootloader thingy. What happen is, i updated the razer phone 2 to Pie, but notice wifi and sim card cant be detect. Even factory reset fails. So i thought of flashing new image on it. KINDA easy on my oneplus, but im not sure where I gone wrong on this razer phone 2, i accidentally unlock the bootloader. NOW the problem is HOW to relock it back? i been follow all youtube and guides all over the place but still fails.
The state of device atm, cannot be boot into Download Mode. Everytime I plug in usb c from Windows, it will boot into unlock bootloader warning page, and continue boot into the homescreen. testing the adbtools, fastboot also to no avail. Can anyone help and guide me how to relocking it back? Maybe i type wrongly on cmd or maybe other android steps not similar to razer one etc....:crying:help much appreciated.

Hold volume down while turning on. Then fastboot flashing lock.

the stock usb doesnt send things correctly in BL mode, https://www.amazon.com/Blackweb-3-Foot-Charge-Cable-Connector/dp/B07SG7P3KZ/ worked for me. with the correct usb cable you should be able to perform the lock commands correctly. can you give us more detail of what you tried on this phone so we know if we need to provide you additional information?

https://developer.razer.com/razer-phone-dev-tools/general-instructions/
"Locking the Bootloader
Locking the bootloader is recommended for security reasons. Some applications will not work with an unlocked bootloader.
Start the Phone in Download Mode with one of the following methods:
Using the adb tool: With the Phone powered on, execute: adb reboot bootloader Enter Download Mode:
Plug in a USB cable to connect your Razer Phone to your computer, Power Off the Phone, then turn it on and immediately press and hold the Volume Down button until “Download Mode” appears on screen.
Lock the critical partitions of the Bootloader first by running this command: fastboot flashing lock_critical
Your Razer Phone will show you a confirmation screen. Use the Volume Up/Volume Down buttons for navigation, and press the Power button to select. Your Phone will reboot."

I can't seem to enter download mode. All I have is fastboot mode and the option to either reboot, close the phone or enter recovery mode. I would really like to lock the bootloader, but I can't seem to be able to detect my phone on my PC even though I installed the fastboot driver.

You must use a USB 2.0 port. The RP2 isn't detected by fastboot when connected to a 3/3.1 port.

You need to go into your device manager and select [ android bootloader interface ] while in fastboot

[FIXED] Fastboot? Recovery bootlooping, but never getting there

Hi All, I need fastboot!
Perhaps someone can help with my brick? I've unlocked the bootloader, installed TWRP and had lineageOS 18.1 installed once. The screen was dim so I tried to flash DotOS. And got a "failed to mount /tmp/com.android.resolv.apex to loop device /dev/block/loop16" error so I tried to reinstall stock 57 ROM.
I did "fastboot flash recovery boot.img" with the decrypted boot.img hoping to get colourOS recovery.
The phone is now bootlooping trying to get into recovery mode. It won't power off or respond to button presses except vol up + vol down seems to delay the reboot on a blank screen.
I was hoping to get to fastboot mode to flash TWRP. Can anyone help? Should I surrender and accept the bricking?

you can get back to stock by install the stock rom, vendor, and kernel with adb drivers and commands.
or
if your mobile is MIUI you can just use the software to revert back to stock rom remember it re-locks the bootloader and again you need to unlock

The phone is currently boot looping.
I can't even turn it off.
It displays RealME/Android logo, then small "> RECOVERY MODE" text at bottom, then "Orange State" text. Repeat..
It has no response to a usb cable - no usb messages in dmesg. So it is not detected by adb or fastboot.
When the battery finally goes flat, my only hope is that I can get fastboot to flash TWRP into the recovery partition. I am not confident of this :-(

Not yet, but I will try the youtube method above..

This recovered the Phone!
But, win10 reported the MCT extractor contained a worm (the python script under linux didn't work). I'm not sure I can trust this phone 100% from now on LOL!

the bypass just deactivates mtk hardware verificaton as normally they have a special dongle they use with the software download
I havent had any issues
I will upload thw bypass i use which doesnt havw any virus

Question Phone stuck in boot loop, unable to get to FastBoot

Hi,
Sequence of steps:
1. Extracted the boot.img from payload.bin and flashed it to the phone. At this point I was able to get into Fastboot
2. While in Fastboot I went into advanced and wiped the "System Settings", and that's when the trouble started - now the phone is stuck into a boot loop forever, I do however get the options to "Power Off" and "Restart"
3. But none of the options above in Step 2 is able to bring me back to Fastboot (and hence into fastbootd either)
Question: How can I get the phone into Fastboot Mode - have tried MSM Tool v4 as well, but that doesn't even recognize the phone

Edit - This seems to have been resolved now, think I had to press Vol Down + Power instead of Vol Up + Power
Was able to enter into Fastbootd as well, will try to proceed with unbricking the phone with a fresh mind tomorrow

FYI for others reading I was able to install magisk by booting the patched file (dump the payload using the python script mentioned above). Running the command Fastboot boot filename boots into the operating system and then magisk can be installed using the direct method.
I assume running this command the phone doesn't actually flash the boot image but could be wrong

Thats right, "fastboot boot <file_name>" loads temporarily your custom recovery of choice. After rebooting your phone, the custome recovery is gone.
Otherwise, the command "fastboot flash <file_name> recovery" flashs permamently your custom recovery of choice to your device.

Hi I have a oneplus 8t and I tried flashing a payload.bin file using fastboot enhanced. after the operation completed I tried to reboot but the phone only shows the logo and then the bootloader unlocked warning message and then turns off briefly, then it does it again and the screen goes black. When connected to the PC, the PC recognizes the devices as android adb recovery devices but i can't do anything from there. Tried the volume up+power combo and it just does the same thing. tried the volume down+power combo and absolutely nothing happens. If i could at least get to the bootloader I could unbrick it but I just can't get there. Any advice

I have exactly the same issue, on a nord 2

How about vol+/vol-&power all together? When stuck that gives me some screen that allows start, recovery (the one where you can enter advanced settings I expect from your description) and bootloader booting.
