Hi all,
A few years ago (well when the devices has pretty much just come out), I ran a mod which i found on the XDA website that allowed me to root my partners Xperia T (LT30P),
Everything has been fine until recently, where I've wanted to upgrade the ROM on the phone, but this is where i'm having some major problems.!
Essentially I cant get the phone to boot into either Flash mode (green LED) or Fastboot mode (Blue LED). I've tried the volume down and then connecting the USB cable to my PC (on which the correct drivers are installed via Flashtool). and also the volume up for Fastboot. Neither work. Unsure if the phone has an unlocked bootloader or if that matters (im a Samsung man and used to working with that, so all the Xperia modding is totally new to me... :/
So far ive tried the following:
-Volume down key and plugging into USB port - Result: Phone remains switched off.
-Volume up key pressed in and then plugging into USB port. - Result: Phone remains switched off
-Enabled USB debugging and attempted to boot the phone into flash mode via ADB (Flashtool option). Phone simply reboots.
-Attempted inbuilt software update - Update downloads, but fails at 25% approx when it reboots and attempts the install.
-PC companion equally unsuccessful on my PC, as cant enable flash mode.
I'm totally at a loss at how to flash a fresh complete build (using a ftf file) to the phone without access to flash mode or fastboot mode. Anyone got any idea or know of any tools that might allow me to to completely rebuild the phone so all partitions are present and correct?
One idea i had was to flash a recovery to the phone using FlashR or alike, but cant seem to get it to work either. Flashr looks to install the twrp recovery, but when i attempt to reboot into recovery via Flashr or Rom Manager (another tool i use but not sure if useable on xperia phones?), the phone simply reboots. SOunds like a damaged or wiped partition perhaps?
Anyhoo , any ideas would be welcome guys! Too good a phone to just leave in the drawer
Cheers
Craig.
Cant you flash a boot.img (maybe from cm11 or something) with inbuilt recovery? You can use this for flashing
Ok, I've started writing this reply and lost everything near the end, started freaking out, calmed down and decided to do it again, cause I know what it's like to have a phone that's not behaving as it should. So here goes the shorter-ish version cause I really can't type everything again...
Make sure your volume buttons are working at all (I mean when the phone is booted). They work? good, procced. They don't? we can bypass that, but you, should get them fixed.
Got to this thread and download the latest build of the ROM http://forum.xda-developers.com/xperia-t-v/orig-development/rom-cyanogenmod-12-neo-s-homebuilds-t2984988
Extract the boot.img file from the zip and copy it to the root of your external micro sdcard, NOT IN A FOLDER. If you don't have an sdcard, put in on the internal storage, again, not in a folder.
Root your phone if you haven't. There are plenty of threads on that here on xda
Download an app called Terminal Emulator from the Play Store
Open the app and type su into the prompt.
Grant the app superuser/root access
The following step is the dangerous one where you can seriously break your phone forever. I'm not responsible for anything you mess up. You alone chose to do this
Run the following command in the terminal (be sure that the $ at the end of the line changed to a # (That means you're in root shell, but it's not important))
If you don't have an external sdcard type sdcard0 instead of sdcard1
Code:
dd if=/storage/sdcard1/boot.img of=/dev/block/platform/msm_sdcc.1/by-name/Kernel
Connect the phone to a PC with fastboot drivers installed
Next execute this command and your phone should now boot into fastboot
Code:
reboot bootloader
If a blue LED lights up, you can happily continue flashing kernels and ROMs, if not report back and I'll see if I can help you
Cheers gents. Going to give this a shot tonight. I read last night that some builds out there where you cannot unlock the bootloader (which you can check via service menu)? Is that now bypassable?

No and it probably never will be. It's hardcoded on the chip. If your phone is bought with a contract binding or it's limited to a single provider, then chances are that you will never be able to unlock the bootloader and flash kernels. It could be that you not being able to get into fastboot is because it's restricted on the device itself [citation needed]. In that case you're screwed and can pretty much forget the whole custom kernel thing. Only ROMs for locked bootloaders

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

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.

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.
I had android GE 4.3 on it, rooted.
I have the original GE bootloader (that robot) installed.
I downloaded the official 4.4 update through android, rebooted for install.
Now after the install the phone does not boot up anymore, instead it goes into RECOVERY and shows that triangle robot.
I tried wipe of cache and data wipe.
Whatever i try I am not able to get this device into fastboot / bootloader anymore!
It takes longer than usual,, it is stuck in that HTC screen since I have unlocked the bootloader but it does not enter the usual menu.
Instead it just directly goes to the robot.
I tried about everything I could think about,
It seems the OTA really bricked my phone by damaging the bootloader so it does not load at all anymore.?!?!
The only USB accessible feature I see is that in the robot screen it registers a device through USB.
Sadly not ADB or fastboot, it is a volume. It even loads as volume but is inaccessible (like a CD without disk)
Windows recognizes it as WDP FileSystem.
I doubt this will help at all, just wanted to note it.
I am about to throw the phone into trash, if it had not been so expensive.. Anything that can be done to repair this brick ?

Now search for the right adb and fastboot driver. There is a .msi installer (adb + fastboot .msi) something like that. Than push the right recovery via fastboot. Voila

Hi,
I solved it.
It took about 30-50 reboots until the phone entered the fastboot menu.
The problem was that the phone kept skipping the whole fastboot menu and went into recovery instead.
A very strange firmware bug caused by the failed OTA
I started to root my phone this morning. I did the HTVDev unlock, flashed twrp, then tried to flash viperboy's disable RW system protect. This caused my phone to just hang at the HTC screen. I let my phone die and was able to get into my bootloader and fastboot. I tried to push the rom via adb but I kept getting the error of no device connected. Then i tried to flash the stock boot.img though fastboot. This brought me back to the HTC screen but now when I plug it in to my computer it shows up for everything and it installs drivers but the HTC MTP Device fails. Now I cant send commands to reboot through fastboot or adb. Im currently waiting for it to die again to get back to twrp or the bootloader. Any advice on how to proceed?
Thanks,

Likely no need to let it die -- a hard reset (hold the power and vol down for a very long time) should bring you back to the bootloader (hopefully). It'll seem like a good long while -- keep pressing.
From there, select 'fastboot' and press the power button, then plug in to your computer (USB). That'll show USB on the fastboot line.
Then, on your computer, open a command window (presuming you're using Windows) in the SDK platform-tools directory and type:
fastboot devices
If that gives back your device ID, you're at least at a reasonable fastboot. I'd flash a good recovery (I use PhilZ, and while it might be foreign to you (CWM style), it lets you load a ROM via OTG cable over USB if you have such a cable -- if not, hopefully sideload works for you in TWRP if you stick with that) -- just to be sure you have a good recovery.
Then, reboot into recovery.
Your kernel (boot.img) apparently is garbage, so hopefully you can either put a ROM on USB and flash from that (OTG) or adb sideload it. All the ROMs normally have a good kernel so would flash your boot.img properly during install. Were me me, I'd flash O.M.J's stock rooted ROM just so you at least get back to some place of sanity).
If that all fails, you might have to RUU and start over.
Let us know and we'll help out.

ok. can you use adb push in fastboot? also i noticed that my captive buttons blink when i tried to turn off my phone. don't know if that means anything.
OMG it worked! Thank you so much. I uber appreciate it. Today I learned a ton about how android works and how to use adb and fastboot. While the processed about gave me a heart attack i did learn a lot. I can not believe how great of a resource xda is. The knowledge of everyone on here is incredible. I cant thank you enough.
Thanks all,
Paris6906
After years fo relying on the XDA community, I thought I'd give something back. I've been for a few days now trying to get the phone properly rooted, however being a bit cautious due to completely screwing up my last phone, was being very careful.
Obviously - This guide carries all the T&Cs you'd expect... will void your warranty, could brick your phone, could fry all electronic devices within a 50 meter radius and such... USE AT YOUR OWN RISK.
Also, credit goes to the people for their hard work in making this possible. I'm only responsible for writing this post.
I'm not sure if you could have gotten away with not doing any of the steps below, but it's this sequence that I followed.. so feel free to play about.
To start off, you need the following
Ingredients
HiSuite software. I used what came with the device. If you put it in HiSuite mode, you should get a folder mounted that contains this software.
USB developer mode needs to be enabled (follow HiSuite's guide as even IT needs debugging mode enabled).
ADB - I used the latest version of Minimal ADB and Fastboot
Download TWRP from here
P7 Easy Update and Adjust from here
King Root from here (I've tried the lot and is the only one I found that actually worked).
Super SU from here. Put it on your phone storage for later.
Preparation
Install ADB, HiSuite and King Root.
Connect the phone to the pc via the USB, turning on PC Suite (HiSuite) mode and USB Debugging enabled. HiSuite should automatically load.. close it
Run King Root and start the rooting process. This should cause your phone to reboot a few times. now, following the application - towards the end of the process it says something about installing a recovery, but (at least on mine) didn't seem to install correctly. Never mind though - phone will still boot as normal, and we'll take care of the recovery next
place the Easy update and adjust excecutable in the folder where you installed ADB and run it (make sure phone is in pc Suite mode with USB debugging again and close the HiSuite app if it pops up on your PC). Note that in the ADB folder you will find a new /recovery/ folder, as well as a stock recovery image. Place the TWRP recovery image we downloaded earlier in this folder as well.
From within the Easy update, select [3] - Delete set_immutable.list / Full root.
After that Select [2] - Flash Recovery (Stock or custom)
Select the TWRP recovery. This will reboot your phone and flash the recovery image, loading back up as normal.
Go back to the Easy update app and select to reboot into recovery. If you attempted this before the last step (7), you'd just see two boot cycles, back into the normal boot up.
flash the Super SU zip and reboot
the next time you boot up, you will get a notification that king user needs something... you need to disable (or uninstall via titanium backup).
And that's it! You have root!

TWRP recovery version?
Hi,
Will I have to download TWRP version compatible with EMUI 3.1 (which is mine case) or I can use TWRP 2.8.1.0 link that is in your post?
Thank you in advance!
When I first purchased this phone I was able to boot to the default recovery that came with the phone ( which clearly had a *fastboot option*), it came with stock 5.1, and a bunch of bloatware.
I downloaded the one click root method for the h811 which was perhaps the easiest root i've ever done. great. i also had to flash my recovery to twrp 2.8 for some reason.
Rocked out to a newely rooted device on 5.1 until the t mobile bloatware and system update notification kept bugging me, so I said * eff it, i've been holding out for a while*
So I get to the cm 13 wiki for my device, I managed to install the cm recovery ( cant remember how i did this for some reason) and then i was able to flash cm13 to my phone. CM13 is sleek, and smooth but is presenting problems.
First of all, no google play store and the gapps zip wont install through cm recovery ( fails and tells me to use twrp instead which is a problem because i can't boot this phone into fastboot mode)
I am unrooted and can not figure out how to properly root a T mobile h811 running cm13, so the twrp manager doesn't work because it "requires root" then shuts down. ( enable root access in the cm13 developer options does nothing at all and yes, for adb and apps)
FAST BOOT MODE DOES NOT SEEM TO EXIST ANYMORE ON MY PHONE - Following the many tutorials, which goes long the lines of using adb/fastboot, adb devices can see my device, but fastboot devices can't ( figures) because its not in fastboot mode. Any fast boot reboot bootloader or any variant of that command only reboots the phone, to... swipe the screen.
I've installed the lg bridge crap ( which installed an updated usb driver) that doesn't even recognize my phone " no mobile device connected". tried uninstalling and reinstalling, but nothing. When putting the phone in download mode, to see if adb would rcognize it, windows sees this as a new device , installs drivers but says " device can not start, code 10 * in device manager. :silly:
is there anything that can be done?? google searches result in obvious solutions that SHOULD work but don't, or threads where a person coincidentally has the same exact problem as I do, but their response is usually the last response in the thread that goes unanswered
summary : I've install cm13 on my lg g4 h811, I do not have root access, I can not install twrp due to ( no fastboot mode) in effect, i cant install gapps, cant root phone etc..
any help?
did you ever unlock the phone....?
Yes, unlocking the phone is one of the first things you would need to do. In Developer Options > OEM Unlock. Then in bootloader, run the unlock command. This will delete /data and internal storage so back up your files so you can transfer them back via adb or fastboot.
Then you're probably going to need to temp boot TWRP, then flash the TWRP recovery image in TWRP. THEN you can flash properly.
Carefully read through this thread:
http://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227
Good luck.
Edit: oh and this thread belongs in Q&A.
Alright. Am I only to read the first post or all 30+ pages? ( not that i have a problem, just curious)
Reeeeaaadd ittt alllll! Just kidding. The first post should be fine. You'll be looking at doing everything after flashing the kdz. If you think you've messed up your partitions, flash the kdz and start over.

"ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it."
didn't work, very frustrating. any clues? on windows 8.1 by the way. tried two computers. none can see this phone. I can connect the phone to the computer and see its storage, lg usb driver is installed
You probably need to reinstall the drivers. It might be the fastboot driver. That's what worked for me.
I've reinstalled the official drivers, uninstalled them... Jusst the mobile USB driver, a combo of both, plenty of times. Don't understand why this software doesn't see my phone
Lgup, lgair, lg bridge, lg USB driver (skinned down) .. Nothing works tested on my gaming rig., and work laptop both running win 8.1 64 bit

This section does get more views though haha.
Anyway I feel that the 811 is one of the more finicky devices to get into fastboot at least in my experience. I had to enable and disable dev options while plugging and unplugging device and it finally worked. No idea if that'll work for everyone though.
I reasked the question in Q and A. Please help some one.
You start over. LG bridge.
Having the same issue. I'm on Windows 10. What developer settings did you mess with to get it working, tiskewlio?
The issue i seem to be having is that when I put the device in download mode ( didnt know that is the same as fastboot) drivers attempt to install, "LGE MTP USB DEVICE" has a yellow exclamation mark with a code 10-device cannot start error message. I believe this the issue as any fastboot command stuff says " waiting for any device" . must not yet see the mtp driver .. Also noticed the bridge app immeditaley tries to pick up my device in download mode but fails due to this problem..
Any clues?

The issue i seem to be having is that when I put the device in download mode ( didnt know that is the same as fastboot) drivers attempt to install, "LGE MTP USB DEVICE" has a yellow exclamation mark with a code 10-device cannot start error message. I believe this the issue as any fastboot command stuff says " waiting for any device" . must not yet see the mtp driver .. Also noticed the bridge app immeditaley tries to pick up my device in download mode but fails due to this problem..
Any clues?

silly question maybe, but is there a specific tutorial in getting this to work with the files provided given my situation? (commands, etc..) will this somehow bypass the the lge mobile mtp device that wont install ? I had installed the system wide adb/fastboot drivers, and already had a folder with just the minimal install of the adb but didnt have a few files in the one you provided ( lg root, busy box, etc) so not quite sure what to do with them.
Again, if possible want to flash twrp recovery to my device but can't due to * waiting for any device* and the ( device cannot start ) error
Thanks
* waiting for device* when putting phone in download mode and pushing fastboot flash twrp-2.8.7.1-h811.img.
Any help would be appreciated as I need to get the driver to work first. see attached picture.

the issue is largly resolved as i've been able to flash the recovery and install another rom. But i'd still like to know how to get the download mode driver properly working in the event i need a computer and can't do a self contained install.
Uninstall all drivers. Reboot computer. Reinstall latest drivers and LG bridge. Reboot. Then start your process. It'll work. Trust me. Find my posts in primes stock thread. I ran into this issue myself. And if you get an error after flashing where it won't mount /data, that's because it got corrupted. Once in twrp, format /data then reboot to recovery. All will be well to flash. Just a heads up since that was also a problem.

i dont know man, i did all that a million times over, but recently i was able to just flash the stock MM rom to the device using LGup. Think i'll just stick with stock rom and root for a while as all this stuff is a little finicky at times. Thanks for your help.
