Some background:
1 - I have installed the latest version of TWRP for the Rezound, and it appears to work fine. Even now. I can even Mount the SD card and transfer stuff to it from the PC.
2 - Any ROM I install from TWRP leads to a black screen on reboot. I see the HTC logo, and then it just goes black. It will then do nothing until I do a battery pull. No matter what buttons I press.
3 - This is not my primary phone and even if I bricked it, it's not a huge loss. Mostly I use it to experiment on so I don't hose my real phones. But I would still like to get it working in case a friend on Verizon ever needs a backup.
I have attempted to install Liquid Smooth ROM and OmniROM with the same result. I had a JB Liquid Smooth ROM on there before and it was working ok. The ones I tried to install were KitKat ROMs.
Any ideas? It is possible I might have accidentally deleted something I shouldn't (wiping caches from within TWRP), but I can't really think of what that would be. When I have installed these ROMs from TWRP it does tell me it was successful.

Not likely... I am assuming your Rezound is S-ON, so you need to manually flash the boot.img using fastboot from the ROM -AFTER- flashing the ROM and gapps or the ROM will not boot. When an HTC device is S-ON, recovery cannot flash the boot.img, so it has to be done manually.
1. Flash ROM and Gapps
2. Reboot phone into bootloader and start fastboot, connect the USB cable
3. In the rom.zip file you flashed, find and extract the file called "boot.img" and place it in the fastboot directory on your PC
4. Enter the command: fastboot flash boot boot.img from the fastboot directory
5. Reboot and give it some time, initial boot on some ROMs can exceed 5-10 minutes.

Thank you, I forgot I had to install the boot.img after. I have been spoiled on the nexus 4 and 5, and forgot what a pain in the ass HTC devices are for this stuff. I had to install their stupid sync program to get USB drivers as well.
OmniROM is working and KitKat is awesome. The UI finally feels as smooth as my Galaxy Nexus.
Okey so I try to enter fastboot mode on my Z2. I hold the volume up and power button. The led turns blue but my screen is still black. What am I doing wrong here?
Ehm... Wasn't it supposed to be black?
I always mess up fastboot with flash mode. Don't you need to connect USB cable and volume up?
P.s I love doomlords Xperia Reboot App! Wort every penny. You can just reboot into flash mode ^^

Well how am I suppose to flash my zip files 0on the SD card if the screen is completely black ? I am pretty fresh to this .I have root but still on stock rom. Wanted to try the 4.4.4 for my Z2 but i dont have CWM installed and i wanted to install CWM but how do i do that if i cant reboot in fastboot mode
well if you are new, you should read for couple of hours first on the forum.
there are many threats with exact instruction.
or should all write same thing 1000x when someonw new comes to the forum?
but in few words
- fastboot is always black screen (you use adb on pc to put files to the phone in this mode, like change kernel with recovery)
- flashing zip is done in recovery (no black screen there)
- before flashing or fasboot entering always read forums first so you know what you are doing...

Unlock your bootloader after backing up your TA files while you're still on 4.4.2. You will loose your DRM keys by doing this !
Install 4.4.4 through Emma.
Download Doomlord advanced stock kernel v7 .
Unzip and copy boot.IMG into your SDK platform tools folder.
Power off your Z2 and hold volume up while connecting USB to your Z2,this way you will enter fastboot mode.
Open command window in platform tools folder and type :
fastboot flash boot boot.IMG
It will flash kernel and CWM recovery,after this type :
fastboot reboot
Your Z2 will reboot , during purple led hold volume up to enter CWM recovery mode,here you can flash update SuperSu 2.16 .zip to obtain root.
Doomlord advanced stock kernel & CWM you can find here :http://forum.xda-developers.com/showthread.php?t=2702001 , Google for SuperSu 2.16 .zip will take you to Chainfire's site.
Good luck,if you're new to this:read well before actingâș
Thanks a lot for the replies. Yes I will read again. I always forget between the times I do this! I have done this many times but with other phone models so its time to fresh up the memory

Hahaha sweet
There is a fastboot and flashmode both have black screen and can only be controlled by a computer and USB cable. There is this awesome "Flashtool" which has a nice GUI for both.
You can flash .ftf and .img files.
If you want to flash a .zip file you need a recovery. You can either flash NUTs dual recovery or Doomlords advanced stock kernel and then boot into recovery.
I have the castor windy version 16gb SGP511. I was previously rooted but not unlocked. I unlocked the boot loader. Installed the twrp image on the pac man thread which i think was dual recovery cause Philz,Cwm came out, so I can install lollipop version of the rom. Made a backup of the stock rom. Followed this instructions - Install the Lollipop ROM + GApps+SuperSU using whatever Recovery you have.
- Turn off device completely.
- Press <Volume Up> and plug USB cable.
- LED should turn blue.
- Send command: "fastboot erase recovery"
- Send command for Castor_Windy: "fastboot flash recovery TWRP_Castor_Windy.img"
- Send command for Castor: "fastboot flash recovery TWRP_Castor.img"
- Unplug USB cable.
- Device will reboot.
- When LED turns pink press <Volume Up> and <Volume Down> several times.
- You should now see TWRP
I wasnt fast enough so stock rom booted. I used Adb reboot recovery to access recovery and did as the above mentioned. Wiped i tried to install the rom which failed. Rebooted back to system and got stuck in Sony boot up screen. I can access fastboot. Read though the forums I have to find a ftf or a system image file and use a flash tool. What ftf file or system image my I use use which will let me root my device again.
Thanks Steve

Try this Xperia downloader tool. Should let you see which versions are which. If you want an easy root, then stay away from the KitKat builds, unless you want to unlock bootloader.
http://forum.xda-developers.com/cro...xperifirm-xperia-firmware-downloader-t2834142
Use Flashtool to flash your downloaded ftf file. Just make sure your device is charged.
http://forum.xda-developers.com/showthread.php?t=2335555
I believe flashtool will even install the drivers for your 511
Thanks for the reply. Flashed ftf file and my tablet is up an running. Do I have to unlock my bootloader again or is it unlocked already?

Well, now this depends.
If you previously had KK running, and flashed a original version JellyBean ROM, then it probably locked the bootloader again.
If you flashed the same version as you had previously installed, then it didn't lock it again.

Thanks. Yes i was unlocked already, went through the process again to verify. Trying to upgrade my firmware which is 17...........402. to a kk build firmware. I have the old cwm recovery 6.0.4.6. being trying to upgrade or even change recovery to any recovery except dual recovery. Through fastboot which none of them stick. Fastboot erase recovery
fastboot flash recovery recovery.img all of them(CWM,TWRP,PHILZ). The process goes smoothly but when I access recovery the old recovery comes up. What seems to be problem? I cant change my recovery or even upgrade it. I never have had this problem before some insight needed before i take a wrong turn. LOL.

You mean the "factory" recovery comes up.
Well, just for info, you don't need to run the fastboot "erase" command when installing a recovery. Not necessary as the new image file will overwrite the existing.
Also, you don't exactly need to flash a recovery either. You can connect via USB, boot to bootloader, and run the "fastboot boot recovery.img (or whatever you named it) as long as your custom recovery is in the same folder as the fastboot.exe. This will just the custom recovery without installing it, thus allowing you to flash stuff.
As to why your fastboot flash isn't sticking, I'm new to the Sony tab, so haven't learned all the quirks yet as compared to Acer tabs.

I mean cwm recovery v6.0.4.6 comes up the one I installed Doomlords thread with the advanced kernel. I ran fastboot erase recovery command to see if the new recoverys would stick and replace it but it didn't. I have done your instructions before hand thats how I am accessing the bootloader. "fastboot boot recovery.img all add this command to see If the new recovery would pop up. Thanks for the reply.

Well, here's what I think is going on.
1. You installed Doomlords kernel. Note that this is a foto-kernel, which means the kernel itself has a partition that contains a recovery. What this means, is that as long a the fota-kernel was not replaced, then that specific recovery will be there.
2. You flashed a normal recovery. Now, I think this is there, but because of the fota-kernel, the fota-kernel is taking precedence.
Like I said, I don't know a lot about this Sony tab and the different partitions,as they are different from other tablets I am familiar with.
What puzzles me, is that if you flash a new "ftf" without changing any options in Flashtool, it "should" rewrite "every" partition on the tab, and install Stock recovery.
Now, based on my experience with Acer A500x and A700x tablets, I can say there are times when your issue happens. Rare, but it does happen. Things say they flash ok, but the old stuff still remains. The only option at that point, was to go back to a totally original version of the firmware.
Not sure I'm helping you on this. But the good thing, is that you can Fastboot Boot Recovery.

I started from zero again flashed ftf Firmware SGP511_17.1.1.A.0.402. Verfied that i was bootloader unlocked I still was. Used fastboot to flash Dooms Kernel, without a problem used cwm revovery to flash Supersu. Tried to upgrade my firmware with the prerooted rooms in thread flashed with out a problem but no difference was provided. Verified in settings and initial firmware stands (SGP511_17.1.1.A.0.402). Tried to flash CM12 got stuck on a bootloop. Fastboot flashed the boot img provided didn't work for me so I flahed Teslas rom Followed instructions provided
1. Make sure you have CWM installed and a working nandroid backup
2. Download the ROM.
3. Place the ROM on your SD-Card.
4.Extract boot.img included in zip and fastboot flash it via Flashtool or CMD
5. Reboot to recovery.
6. Wipe data-factory reset/cache partition/dalvik cache
7. Flash the ROM.
Flash went through but when I try to access recovery through the rom or adb recovery doesnt come up. The tablet just stays black on recovery screen and the tablets led turns yellow. I have adb access so went to access fastboot flashed different recoverys. None of them (flashed without a problem), work but if a flashed Dooms I have access to recovery again, but loose functionality of the rom it gets stuck on sony screen. I have to do the steps all over again without a working recovery. This has being a learning experience I am HTC guy so the process with sony products is new to me as well. So where do you think I should go on from here; flash a newer ftf or lock and unlock my bootloader again to see if something happens or just move on jajajajj . Anyways thanks a lot for your help.

Well, I'm not sure which route to take.
However, I will tell you what I have learned the other day.
I have the 521 with unlocked bootloader. Rooted with my own boot.img, flashed SuperSU using "flashboot boot recovery.img" (yeah, sometimes it doesn't show on the display, so it takes a few times).
Now, other day I was going to check out the new LyPop pre-rooted. Fastboot flash recovery recovery,img, and it won't boot it to recovery like it should. Like it's not flashed. Tried it a couple times. Now, I didn't install the dual recovery as I'm not sure how that kernel (boot.img) will interact with my current tabs OS. Not to mention I need it for my work until tomorrow. But strangely it sounds like the same issue you have.
This weekend I will investigate it. As for me, I will probably flash the Stock ftf lyPop build, and just root it using a modified boot.img.
One thing I do know, is flashing a custom recovery to the "recovery" partition, doesn't seem to work like it used to work on other devices. It seems the flashing to the "Fota kernel" partition seems to be the only method that works. This is what happens when you flash that dual recovery, or any recovery that has a boot image using "Fota". Probably explains why you can't get rid of it using "fastboot erase recovery". because it's erasing the wrong partition. Only flashing a full ftf gets rid of it, because the ftf has a new FotaKernel it flashes.
Eh, something like that. Will look at it this weekend.
Hi, i've had my Z2 two years now and I've rooted, UB and installed roms on it many times but for some reason I can't get into recovery anymore. I flashed a different ROM a few months ago to try get it back to stock but since then, no recovery!
I've flashed the TWRP 1 click installer (only seems to work on laptop, on PC I get waiting for device but it says it worked on laptop) but still I can't get into a recovery to flash a custom rom.
Any ideas? How do I get recovery back? Please be a bit simple with me, i've googled it and just get overwhelmed by the info so figure I should ask and find out what actually applies to me..
Thanks.

If you have flashed a stock rom, you probably have locked your bootloader, try this (hope you have done a TA backup the first time you unlocked the BL...):
Download the Androplus kernel in development section, unzip it.
Then, download and use flashtool (install the drivers if need them) to unlock your BL again (BLU button).
Once you have unlocked it, disconnect the phone from the computer BUT DON'T BOOT IT.
Close and reopen flashtool, and select fastboot mode from flashtool and use the kernel flash option.
Select the boot.img you have unzipped from androplus (change the file extension to .img), and your are done.
Disconnect, reboot and you will be able to access the TWRP recovery from the kernel when you see the led, then flash a stock based custom ROM (with recovery), or CM one, try to have one of them downloaded and placed into your ext-sdcard.
PLEASE! My English is not good enough to explain this in a better way, if you don't are familiar with flashtool, fastboot mode or you don't understand any of the steps, wait for a better explanation or read a lot about it BEFORE doing nothing.
PS. Your internal data probably will be lost, make a copy of all your photos, docs, etc. You can relock your BL if you choose a stock based custom rom like eXistenZ, just restoring your TA backup after flashing it.
have u try flash via adb fastboot? it's easier when u have UB, try erase it first, "fastboot erase recovery" then flash the img (the latest twrp img is available on their site) "fastboot flash recovery recovery.img"
Hi,
I've got a Z2 on android 5.0.2. I successfully unlocked the bootloader (through the Sony site) thinking that flashing TWRP would be easy then. It was a piece of cake on my Z1 compact, but I can't get the Z2 to boot into recovery. I downloaded and flashed several TWRP versions (including the one from the TWRP website) with both
Code:
flash recovery
and
Code:
flash FOTAKernel
. Flashing seems to be going OK, but the phone keeps booting Android. I tried adb reboot recovery and holding vol down and power.
I'm probably missing something. I went through a bunch of posts, but can anyone explain to me how I can flash a custom recovery to this one and actually boot into it...?
OK...
I thought I found the answer and flashed the stock-17.1.1.A.0.402-sirius-repack.img to boot (that number in there should have rang some bells...). It helped getting me into TWRP, but now I'm stuck in a nice bootloop.
Is there a way to get out of the loop and stay on the ROM (stock) which was on the phone?
1 - Install Adb installer
(https://forum.xda-developers.com/showthread.php?p=48915118#post48915118)
2- Download the twrp.img that matches the os.
(https://dl.twrp.me/sirius/)
3- Copy it to c:adb.
4- Open a CMD as admin.( just to be on the safe side)
5- Type in
adb reboot bootloader
fastboot flash recovery <twrp_image_name>.img
adb reboot recovery
7 - If everything goes well,your phone will reboot into recovery.
If things are unclear refer to this guide
https://www.xda-developers.com/how-to-install-twrp/
Let me know how it goes
