Okay, so i am using a xperia z2, cant rmb the version of the firmware, but i successfully rooted my device so i went on to try and flash cm11 onto my device. However, upon flashing cm11 and gapps into my phone through dual recovery i was no longer able to boot up my phone. Holding the power switch causes the device to vibrate, like perhaps every two seconds, but does nothing meaningful. Holding the powerswitch and the volume up key boots into fast boot, which is just a blank screen, but with the blue led that i read on the internet meant fastboot. Problem is, I am unable to get windows to install the relevant drivers for S1 Fastboot as it is displayed on my device manager window, and nothing i try will help. Ive downloaded usb drivers from numerous sources, including but not limited to flashtool, and nothing can get the fastboot to be recognised by the computer. Kindly advise on what i could do to restore my phone please! any help is greatly appreciated!!!!
I live in Singapore and i understand that bootloaders are by default unlocked? I'm not sure if i have to install any form of kernel , but i have a feeling this may be the cause of the problem? Please be kind, I am new to this entire rooting business. Once again any assistance is greatly appreciated!

Folow this to unbrick your device
You need an unlocked bootloader to flash cm11, no bootloader comes unlocked
There is unlockable and non unlockable

Hi all
Let me expose my problem :
I got an unlocking key from sony ; when I use it with
Code:
fastboot oem unlock 0xDEVICESKEY
, the boot process loops : I can see the sony logo, then the Xperia logo, then a few colorwaves, which in turn stalls for a second or two, and then the device reboots.
I tried to flash the device with kernels adapted to SGP312. Flashing succeeds if I unlocked just before (if I want to re-flash I have to re-unlock), but the device then doesn't boot at all.
I could never access recovery, but I read this thread saying that's normal with stock kernel. Though I couldn't access it having flashed any other kernel.
Thus I'm locked into android.
Can anyone help ? I discussed this with Mamenyaka, he suggested I posted my issue here. I tried to find a similar case in the forums but couldn't figure anything close to this.
I finally found a solution to my problem : I unlocked the device using flashtool-0.9.11's gui procedure, instead of flashtool's fastboot. It succeeded and I can successfully flash anything I want on the device.
Hey guys,
I am sorry if I am in the wrong place or am asking something wrong. This is my first time using these forums (and forums in general). If I need to be somewhere else kindly redirect me.
Anyway, I was with Verizon for a while but after some shady stuff I decided to break up with them. Beforehand I had bought outright a Sony Xperia Z2 Tablet. Because I did not want anything Verizon on it I decided to root it, and flash a good ROM onto it (Cyanogenmod was my idea, but at the time I don't think they supported it? I'm not good with ROMS). Anyway, the rooting was completely successful and I had a custom recovery (TWRP) installed. I was ready to flash the ROM. Unfortunately, I wasn't paying attention and grabbed the wrong ROM. What ended up happening is when I attempted to reboot after "flashing", the device didn't show anything on the screen and just kept vibrating. After some digging around I found it might be "soft-bricked". I had at one time found a guide that told me how to undo this by using SDK Tools and Fastboot Mode (blue LED), but cannot find the guide anymore.
I was wondering if ANYONE could help me undo this mistake, and get the tablet back to it's original state or with a nice compatible ROM. I am currently in Fastboot mode and it is plugged into my ASUS Laptop running Windows 7. Any and all help would be GREATLY appreciated. Thank you so much for taking time to read this.
EDIT: So a breakdown is I cannot interact with the tablet directly. There is absolutely no interface. Just a screen that won't turn on. Meaning if there is a method it can't be done on the tablet. The old guide I found was explaining how to do it through Windows while the tablet was plugged into it via USB.
Also the bootloader was never unlocked so I think that was also an issue.
First of all, if your bootloader is locked, you cannot install CM because you cannot change the Kernel. You can only use Sony-certified Kernels which won't work with CM. So Sony-based ROMs are your only options
But what you can do is:
- Go into fastboot mode (turn off your tablet, connect it to your PC and press volume up. If the blue LED shows up, you are in fastboot)
- With fastboot, you should be able to flash a ROM (preferably Android 4.4, so you can root again)
- Then root, install dual recovery
- Flash the correct ZIP
Alternative:
- Unlock Bootloader
- Flash recovery
- Flash CM

Can you simplify this? Where do I find the ROM (again, this was a tablet from Verizon so I assume on top of the Sony ROM I need the Verizon version of it?) And I understand I cannot install CM unless the bootloader is unlocked; do you know how to do this?
I'm confused by the first set of instructions as I cannot use the tablet directly. How will I flash the ROM (and which is the right ROM and where can I find it?) through the computer since the tablet can't be interacted with. There is absolutely no interface to interact with whatsoever. Which ROM do I download for the Verizon Sony Xperia Z2 Tablet and how do I flash it using Fastboot? I assume I do it thru my computer?
Sorry, but you'll have to Google a little bit - I haven't had your exact problem.
But as long as you can get into fastboot mode, nothing is lost.
There also is the Sony ftf tool or so, the Windows program name is Emma. This should be easier than using fastboot.
Also there is a sony site for bootloader unlocking. You can check whether your bootloader can be unlocked at all.
hi all i have lg v10 h901 21j
i tried to root it i download tot file LGH901AT-01-V20j-310-260-JUL-12-2016-ARB02+0ROOTTWRP
when i flashed it phone off and cant on please help
stock rom H901 21j please and how can i flash it cause phone is dead please please help
please guys help the tot file from here https://forum.xda-developers.com/tmo...-h901-t3382819
when flash finish phone off and cant turn on please help
my phone model H901 21j
same issue . ihave h901 running on 5.1 update it via lg up to 6.0 20e then its bricked . pc read it as qualcom hs-usb 9008 . any help/ solution
Is there a reason this thread has been ignored? I also have a LG V10 H901 21J MM/6.0 stock firmware.
I have not as of yet flashed a .tot file to it, because I am not sure that the .tot files for other H901 phones is correct. I have heard different things, regarding this particular version, which I have heard is a Korean version of the phone, I am not sure if this is applicable or true, but apparently this may mean the phone has a different board than other H901s out there.
What I can say for certain is that I was unable to unlock my bootloader, due to the inability to reach Fastboot/Bootloader moder from this phone using any of the normal methods which work on my other LG V10 901. The procedures I have followed to get into Fastboot/Booloader mode are: (a) Shutting down phone; --> Pressing Power-Off, and Volume Down at the same time, holding for 5-6 seconds after the LG screen appears, which just causes the phone to boot normally, (b) running <adb reboot bootloader>, which again just boots normally, it does not go into the bootloader/fastboot mode; and (c) Power down /turn off the phone, once off, hold down Volume Down, while you plugin a USB cable into the phone(that is already plugged into a computer with good drivers on the phone), continuing to hold down the Volume Down until you reach Fastboot, again same results and this does assume that the USB cable is plugged into a computer with good drivers.. Just for the record for the methods listed that involve having the phone attached to the computer, I have tried this with the phones USB in both Multi-Media Mode, and PTP mode, without a difference being made, and it should be mentioned that I have successfully performed all 3 methods on my LG V10 H901 20L running stock MM, which was successfully rooted using the Dirtycow exploit. Yes, debugging is enabled on the phone, and although it does not effect getting into Fastboot mode itself, OEM UNLOCK is enabled.
If I could get into Fastboot on this phone, and get it unlocked, then I should be able to use the Dirtycow exploit in order to get temporary root, that would of course allow me to then flash TWRP recovery directly to the recovery partition, and solve the issue.
rabahallia I know that this is almost a year late, but can you tell me if your phone was unlocked when you flashed the .tot file, and if so, how did you go about unlocking it? Also, I can tell you based on the chipset that the phone runs, that you should be able to image a microSD card using a ROM designed for the phone, and then boot using the flashed sdcard image. If you are not able to do that, then can you tell me if now that your phone is bricked, is the phone turning on at all, or just not booting fully? Can you attempt to get it into Fastboot mode now, using the methods I described above? You will have the highest chance of success using the 3rd method in terms of being straight forward, and of course the fact that your phone is not booting again that involves: plugging a USB cable into your PC, then, shutting down your phone which is not a problem in your case with your phone off, hold down the Volume Down button on your phone, while still holding down the Volume Down plug the USB cable into your phone, and continue holding Volume Down until your phone reaches the fastboot/bootloader menu. If you are able to do this, and you DID NOT unlock your phone before you flashed the .tot with the modified recovery onto your phone, then unlocking the bootloader at this point may allow your phone to boot. To do this, after you have reached Fastboot/Booloader, you will use the command <fastboot oem unlock> wait for it to finish, and it should inform you that your phone is now unlocked, then you can reboot your phone using <fastboot reboot>. Please let me know if this worked, or if you still have the phone, if you could try this. I am interested to know if flashing the .tot to a phone that can not be unlocked due to inability to reach the bootloader/Fastboot mode, as you may have done, would allow that mode to be reached after bricking the phone, and if so, if unlocking the phones bootloader after the fact, fixes the issue. If this does not fix the issue, but you were able to reach fastboot/bootloader, then you should be able to reboot back into Fastboot mode, and then flash a recovery, which would in turn allow you to flash a new ROM to the phone. If anyone else out there has any information SPECIFICALLY ON THE 21J version of H901 stock MM, please provide any information you may have. Or if you have any information about what board is running on this phone, if it is not the same board running on every other version of the H901 such as the 20J, 20e, 20L.
Hey everyone,
My questions are at the end below, but they need a bit of history which might be useful to someone in similar position.
I have SGP321 and used it stock for a number of years without much issues. Lately though it seems the age of the device shows itself and I wanted to try a custom LineageOS ROM on it - I 've done this before with several other devices.
I tried to follow this guide - [Guide/tutorial] Sony Xperia Tablet Z LTE or Wifi Any version to Android 8 - however the service menu of the tablet showed that the bootloader cannot be unlocked. Attempts to unlock the device using fastboot oem unlock 0xYOURUNLOCKKEY using and unlock code from https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/ showed that the bootloader of the tablet is indeed locked and the lock cannot be removed. I also tried to use the Flashtool to unlock the bootloader - again unsuccessfully.
Being stubborn as I am, I rooted the tablet using this guide - [Guide][Easiest Way]How to Root Xperia Z Android 5.1.1 Without PC and Get SuperSu - which works for Tablet Z as well. Having root access gives possibility to work around the bootloader lock to some extend since access to the tablet storage happens from the OS. I proceeded to copy twrp-3.3.1-0-pollux.img to the external sdcard of the device and executed from a root terminal on the device:
dd if=/sdcard1/twrp-3.3.1-0-pollux.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel​which completed without complaint, then I rebooted and tried to enter recovery by using repeated presses of volume-up and volume-down buttons as well as other combinations like holding them pressed simultaneously, combining the volume buttons with the power button - no positive result (most probably as I read later because the stock BL doesn't support recovery). Then I decided to install the official TWRP app and the used it to install the image to the recovery partition - again no result booting into recovery. Then (foolishly) I used the app to try to install the TWRP image in the boot partition - no problems there, however on the next reboot the tablet was bricked
In this state when trying to power-on the tablet the indicator LED starts flashing in red and the screen remains black. Power-off was possible through pressing volume-up and power buttons for more than 10 seconds. It was also possible to enter fastboot mode by powering-off the tablet and holding volume-up while inserting a USB cable that was plugged to a PC - success was indicated by a continuous blue indicator LED. Attempts to use fastboot flash or fastboot boot with TWRP image didn't give any positive result - the first failed with "Operation not allowed", the second failed with "Too many links". I also tried the same with kernel.sin and fotakernel.sin files from the stock ROM FTF file downloaded using the Flashtool - again unsuccessfully.
Using the Flashtool itself to restore the stock ROM failed initially because the on-screen instructions for getting into flash/download mode - powering off and then holding the volume-down button while inserting a USB cable that was plugged to a PC - didn't work in my case. Then I decided to use this sequence:
powering off
first pressing and holding the volume-down button
second pressing and holding the power button
finally - inserting a USB cable that was plugged to a PC
I was awarded with short green flash of the indicator LED and the Flashtool recognized the device as being in flash/download mode. I then proceeded to flash the downloaded stock ROM using the default settings. The flash was successful, and I was back to square one. I also rooted the device again as described above.
My questions:
Does anyone know of a method that allows to use the root shell of the device itself to remove the bootloader lock? For example, custom copy/flash using the dd command from a root shell and partition images extracted form TWRP/Custom non-stock ROMs.
Is it possible in the situation of my device to install/flash custom recovery/kernel/ROM if we assume that the bootloader cannot be changed?
Thanks in advance for your time and thoughts...

Hello!
1. If you have operator carrier device like DOCOMO or Orange, then you're out of luck. Carrier branded devices cannot be unlocked, so no TWRP and custom ROMs like LOS, RR, CR, etc.
2. If you have ordinary device, you can unlock the bootloader and install whatever ROM you like, no limitations here.
Root access nor recovery are needed for bootloader unlock.
Thanks Rootk1t, the device was purchased and is locked to a local carrier - so I guess I'm out of luck.
Still, a valuable experience while trying to flash it and having it rooted might allow to squeeze a bit more life out of it

Stock 5.1.1 + root + XZDR + Xposed + some mods (like SDFix for Lollipop; XReality+SuperVivid; xLOUD) is not bad at all.
Hello everyone.
I'm going to tell you my problem and its story
I have an Asus Zenfone Max M2, I unlocked the bootloader, installed a magisk manager to root.
I decided to go further and install a custom ROM (I decided to install Pixel Experience version android 11 (Plus edition)) I did the procedure as recommended by the developer (Saalim) I even saw a related video on how to install Pixel Experience, I followed the instructions step by step, once the flashing process is finished.
I am about to restart the cell phone, and I find that at the moment of restarting the cell phone it only enters fastboot mode, no operating system, no recovery, just fastboot.
Investigating the solution was to reinstall the firmware, I did everything following the steps of the tutorial, once the process is finished and I decide to restart.
It sends me a message that says "Red State Your devices is corrupt turning of in 30s", I thought it was a problem that was when installing the firmware, I entered fastboot mode to try the process again, but in the middle of the process the cellphone was thrown by my pet and disconnected from the USB cable that was connected to the computer, quickly reconnected the cellphone and left continue the process, once the process is finished the cell phone restarted alone and what a surprise.
The cell phone starts with the black screen and with the notification LED in red, when connecting the cell phone to the computer it makes the connection sound but it is not recognized by adb nor fastboot.
PROBLEM: Devices no fastboot no recovery only black screen and the notification led in red i think is hard bricked
If you have any solutions, a hint would be appreciated
good day
