So I updated to a new ROM and I have damaged my recover or I need to update recovery somehow.
The ROM launches and I have ADB support but not google play services or root working
I can access my bootloader (blue LED)but I don't know how to fastboot a new recovery from there
When I go to access recovery (pink LED) the recovery never loads. It used to be a CWM/TWRP dual boot, neither are working.
So I am guessing I need to flash a boot.img from the bootloader using fastboot? I can't find any boot.imgs anymore. Just all this one click **** that doesn't work at all for some reason.
Advice?
On which ROM are you?
Is it AOSP, CM or Stock based?
Is your bootloader unlocked?
If you are on windows, try using nuts dual recovery installer (if you are on stock based rom). But before u use it, u should install ADB system-wide or try to put it into a folder directly on C:/
If you are on e. g. CM12.1 you need to "fastboot flash recovery recovery.img" (you find them in the General Section)

Ok, so lots of info here you might want. =)
Yes Bootloader unlocked. I WAS on paranoid ROM kitkat. It pushed a LP OTA update, which silly me, I installed. So right now the phone is on an AOSP based LP ROM, coming from a KK ROM. There was a dual recovery approperiate for that PA KK ROM installed before.
Anyway, I downloaded a recovery from the link you posted and I am currently installing a backup from before I did all these silly and naive things. =p
My next project... How do I go back to stock so I can try a none AOSP ROM? (o:'
two ways :
- you can download a stock rom ftf file from the official thread here, then use flashtools to flash that file (a more complicated version would be to create your own ftf file using xpirifirm and flashtools), OR
- You can download a pre-rooted zip (also available on the forums here) and install that through your current recovery.
Either way make sure you do a full wipe, stock and AOSP don't like each other much from my experience.
http://forum.xda-developers.com/xperia-z2/general/ftf-cutomized-23-1-0-726-cda-1281-9809-t3082166
1. Go here and download the 23.1.A.1.28 FTF and prerooted zip. (It's the latest stock firmware version) and copy the zip file on your phone.
2. Go to recovery
3. Do a factory reset (wipe)
4. Flash the prerooted zip
5. Shut down your phone (NO REBOOT!)
6. Go to Flashtool -> Flashmode and load the FTF file
7. remove everything in "wipe"
8. on "exclude" tick the following: PARTITION, TA and SYSTEM
9. Click on flash and connect your phone via flashmode and let it flash.
10. Disconnect your phone and start
11. You are done. let the phone boot and settle and reboot one time. Now you are on stock with recovery and root.

Hello. As the title says, I need help flashing a recovery to my Sony Xperia Z Ultra (c8606) with unlocked bootloader. I have tried using FlashTool to flash the TWRP img file found on their website. I connect the phone to fastboot mode, click on Select Kernel to Flash, and select the file labeled: twrp-2.8.5.0-togari. The file flashes, but always softbricks my phone (The LED light flashes red when it is plugged in, and holding down the power button only causes the phone to vibrate briefly every couple seconds). This forces me to re-flash a FTF file (C6806_14.5.A.0.242_Customized USA.ftf) to unbrick. I have tried flashing other kernels (108_DualRec_Jackie099) and other FTF files (C6806_14.3.A.0.681 US_Unbranded.ftf), with the same result.
Can anyone tell me what the problem is and what do I do? I want TWRP recovery installed on my phone (preferably the one found on their website), but everything I have tried just bricks my phone.
Please help me!
Okay, this is a bit complicated TWRP must be flashed to the fota partition of the phone, either using the fastboot command "fastboot flash FOTAKernel image.img" or, if you have rooted your ZU, then install an app called Rashr, open it and install TWRP from the app, just follow the instructions BUT it is useless on stock roms because the stock kernel doesn't support loading a recovery from the fota partition, although all AOSP and CM based roms supports it and there also was a stock kernel that supported it, I have forgotten its name. You were trying to flash the recovery as the main kernel but the system obviously can't boot from it, that is the root of the problem, it would be perfect if it were working that way
Regards
If you're trying to flash recovery or kernels you can use rashr on the play store. If you want twrp download nuts flushable recovery and flash it with twrp manager on the play store.
Rooting Method for Xperia Z Ultra Lollipop V5.1 .

As a Start, You Gonna have Lollipop 5.0 with Root & Recovery installed .
Move 5.1 to firmwares folder .
Download This SuperSu Flashable file and move it to SDCard & Internal Storage .
Open Flashtool .
Select The ROM .
Exclude Kernel ONLY .
Flash the ROM .
Boot the Phone and enter Recovery ASAP .
Install the ZIP File, if Flashtool didn't wipe Internal storage yet, then install it from Internal storage, otherwise from SD Card .

As a feedback from my friend, he said there was not problem with 5.0 kernel on 5.1 system for first boot ( recovery entering only ) .
Please feedback, and don't forget the backup !
is it 5.1 or 5.1.1?
The quick way to root any ROM, including the newly released 5.1.1 is, if you have an unlocked bootloader:
- Hotboot any custom kernel with a recovery (fastboot)
- Flash SuperSU
- Reboot
If you want CWM/TWRP:
- Flash NUT's Dual Recovery kernel through fastboot
- Reboot
You're now rooted, and you have recovery.
NOTE: If you have no idea how to use fastboot, then you can use QuickIMG. It lets you flash .IMGs very easily without needing to use any commands. Do however read the instructions provided before you use it.
It's also a good idea to learn how to get out of a sticky situation in case something goes wrong. If you want to be on the safe side when testing kernels, hotboot, or boot an IMG/kernel instead of flashing. Once you see that the kernel is indeed working, and you're not experiencing any bootloops or red LED blinking, then you can safely flash it to disk.
Note: Hotbooting means that the device will only boot the kernel once, so it doesn't really flash it to the device. Flashing a kernel writes it to the device, making it permanent until you replace it by flashing a different kernel yourself.

thanks i'll give it a try
I have unlocked my tablet using Sony Developer tools. I then tried to downgrade with flashtools to a kitkat firmware . I tried 2 different firmwares for SGP 321 but both give me a boot loop.
I am using flashmode to flash , should I use fastboot mode?
any other firmware I should try or settings in the flashtool?
these are the ones I tried: SGP321_4.4.2 _10.5.A.0.233 3AT .ftf. SGP321_10.1.1.A.1.307_Customized_FR.ftf
All I want is a rooted tablet z with whatever firmware on it.
Appreciate your help
When you say boot loop, do you mean the screen goes black and starts to boot again?
Or do you mean the boot animation is repeating for a long time?
The first time you boot up after flashing an ftf will take a long time. It can range from a few minutes up to tens of minutes.
Did you select wipe USERDATA when you flashed the ftf in flash mode?
Try that if you haven't. See attached screenshot.
Checking it will wipe all your apps, data and internal storage.
I'd recommend you use the latest ROM, 10.7.A.0.228. Root and Xposed works on Lollipop 5.1.1.
Here is a Generic Germany FTF 10.7.A.0.228.
You'll need to root it by flashing supersu zip in recovery.
If you don't have a recovery flashed/installed, you should flash one.
Let me know if you need instructions on installing a recovery.
fantastic, that little trick did the job and I am now on 4.1 .
I am considering now to flash your firmware but could you give me some detailed instruction on what to do please, especially the recovery part.
thanks a lot again.
No problem.
Requirements
Program to open ZIP files
Flashtool (flashtool.net/downloads.php)
Flash mode and Fastboot drivers installed (Comes with Flashtool. Find the installer at C:\Flashtool\drivers\)
A few things you should know about recovery
If you plan on using an official Sony ROM with an unlocked bootloader, the recovery needs to be part of the kernel image.
Sony's official kernel images do not contain a recovery.
The kernel gets overwritten when you flash new ROMs (Official and Custom), so you will lose recovery every time you flash a ROM.
Thus you must reflash the kernel with recovery every time you change ROMS.
Kernel's for different versions of ROMs should not be used interchangeably.
It always best to use the kernel made for the ROM.
Flash official ROM before flashing recovery
If you are planning on using an official ROM, flash the official ROM in Download Mode before flashing the recovery (for the reason mentioned above - kernel gets overwritten).
You should wipe USERDATA to minimise compatibility issues.
Do this first before proceeding.
Downloading a kernel with recovery
Fellow xda member [NUT] has an awesome kernel builder tool which allows you to create kernel images with built in recoveries.
Head over to nut.xperia-files.com and navigate to XZDualRecovery > Kernel Builder
Check the checkbox "Yes, I have unlocked my bootloader!".
Select the Make and model of your device (Xperia Tablet Z SGP321 in your case).
Then select the firmware version you will be using (10.7.A.0.228 in your case).
Cross your fingers. If someone has already uploaded the kernel for that version, you can simply download the link provided. Otherwise you will need to upload the kernel. If you have an FTF, simply open it as a zip file and upload the kernel.sin inside.
Flashing Kernel with Recovery
Open the zip file downloaded from the Kernel Builder and open the tmp folder. Extract the boot.img file inside the tmp folder to somewhere on your computer.
Open Flashtool.
Click on the Flash Icon.
Select Fastboot mode.
Click "Select Kernel to Flash".
Put device into Fastboot mode. (2012+ devices: Press and hold VOL+ button while plugging in USB cable)
Once connected, a file selection dialogue will show. Select the boot.img file extracted earlier. You may need to select the type of file (sin, elf, img) before you can see the file in the explorer.
Flashing will start immediately after selection. Check the log and ensure there are no errors.
Unplug the USB cable.
You now have recovery (Two recoveries to be specific - as XZDualRecovery has PhilZ and TWRP).
I would recommend TWRP as it is easier to use and has more features than PhilZ (Based on CWM).
The VOL+ key is associated with PhilZ and the VOL- key for TWRP.
To enter recovery, simply turn the device on and when the notification LED turns Magenta (Pink) start pressing the button associated with the recovery you want to use.
e.g. Press VOL- a few times for TWRP.
Flashing zips
Copy your ZIPs to your SD card.
In TWRP, tap the Install button.
Select the zip file you want to flash
Swipe to the right to start flashing.
Rooting
Download the latest SuperSU zip (download.chainfire.eu/supersu)
Copy to SD card.
Flash zip in recovery.
Enjoy root.
about to start the process, just wanted to clarify some things:
what zip files are you talking about putting on my sd card? is this the file I downloaded from NUT?
thanks again for your help
Just in general, to flash a zip, you would perform those steps.
You would want to flash the SuperSU zip to get root.
You can also flash the file downloaded from NUT.
It will install a program called NDRUtils which will allow you to reboot into recovery from within Android.
I just saw when I wanted to flash the firmware from your link above (Here is a Generic Germany FTF 10.7.A.0.228.) that this identifies as for device C6603. But I have SPG321.
Do you have a link to a firmware which would work with your way and is for my device?
Oh, sorry about that. Forgot to check the model. I grabbed it from XperiaBlog.
I think I should just explain how to download and create an FTF for yourself from Sony's servers.
Install the latest Flashtool if you haven't already.
Start Flashtool
Click on the XF icon (The rightnost icon)
In XperiFirm, select the series and model of your device (Xperia Tablet Z > SGP321)
Then select the Market+Operator for your country/region. The market only differs by the apps that are pre-installed, which can be removed. Your region may not have the latest firmware available, so you can click the "Check All" button to get the versions of all the markets. You may wish to avoid commercial Operators as they can have different boot logos etc. Download a "VMo" or "Customized" operator if possible. The 228 firmware is only out in a few regions at the moment, so Germany VMo DE would be a good choice.
After selecting a row for the firmware you want, click on the latest version near the top right corner.
A window will show the details of the ROM. Click Download to start downloading. The downloads will get saved to FlashTool's Firmware Download folder.
Once the download completes, close XperiFirm.
In Flashtool, Click Tools > Bundles > Create.
Select the downloaded folder (Which should be in C:\Users\<Username>\.flashTool\firmwares\Downloads).
Double click in the device field to select the model of your device
Branding should be set to the Operator you downloaded (e.g. Generic DE)
Version should be set to the ROM version (e.g. 10.7.A.0.228)
Then in the folder list, select every item except for .ta files (e.g. cust-reset.ta, fota-reset.ta). Click the -> button to add to the Firmware Content.
Click create.
An FTF file will get created in the firmware folder. You can start flashing it in Download Mode.
If you need some screenshots. The procedure may differ slighty.

This might help you after realizing that you want to install custom ROM again after upgrading to android 11 MIUI but you cannot install android 10 or 11 based ROM and stuck with either boot loop or android rescue party.
WARNING: This might wipe every writable partition. Charge your phone at least 20% or more to prevent from destroying these partitions.
Instructions:
1. Download firmware from here
2. Download full ROM (either recovery or fastboot) from here
3. Save the firmware zip file it in either internal storage or sdcard. Reboot to TWRP afterwards
4. Tap install and find the zip file in your storage and install. Wait for a couple of seconds to get done.
To install full ROM
Recovery
1. After installing firmware from recovery mode, don't reboot. If you reboot the system it will fail to boot. Boot to fastboot if you fail this step and flash a recovery image. Proceed with next step.
2. Install full ROM flashable zip from sdcard or internal storage.
3. Format /data. Reboot.
Using fastboot
1. Boot from fastboot mode
2. Extract full ROM fastboot zip file.
3. Open miflash and locate the fastboot folder.
4. Choose flash_all. Click start.
5. The phone reboots itself. Boot to recovery mode and wipe data.
All done. The phone is now downgraded from android 11 back to android 10.
Note: I got 2 anti triggered when attempting to downgrade the phone using recovery and fastboot without installing firmware zip file first. RIP me I guess I voided my warranty anyways so doesnt matter as I already applied some insurance for my device.
TL;DR: Installed Recovery will get erased as I mentioned in WARNING. Please don't skip every step.
Edit: since it made confusion, I split steps for recovery and fastboot mode.
Has anyone tried this procedure?
Im on 12.0.6.0(EU). Bootloader locked (wait 3days) so no TWRP. Want downgrade to 12.0.8.0(EU) and flash Pixelexperience ROM.
It will work?
I'm a bit confusing... Links inserted in first 2 points seem to be the same link. So what I've to download exactly?
I'm on 12.0.7.0 Android 10 but I'm curious to try 12.0.6.0 Android 11 stable beta released some days ago...

Its not the same. First one is cca. 80MB of size while full rom is 2.4GB for recovery and 4.4GB for fastboot.
I did this method yesterday and its working. No problems whatsoever.
The only thing i would add is you need both versions of rom - recovery and fastboot. Recovery when you flash for the first time in recovery and fastboot when you flash with Mi flash.
And my advice is, android 11 miui is really bad. Its not finished, it stutters a lot, u can't use third party launchers with gesture navigation (at least in my case, Nova lanucher), performance is bad.
Not worth any time.

i only tried recovery method and it works fine after days of trying. 12.0.6 android 11 is still buggy and miui needs to fix it a lot. most of apps are not well optimized for this flavor.
Today unlocked bootloader. Flashing 12.0.8.0 (i have 12.0.6.0 A11).
Everything work perfect. No bootloop, bootloader relock and works fine
People are probaly skipping some steps.
1. Download Firmware small size files
2. Download full Firmware, both - fastboot and recovery (put it on SD card, small and recovery)
3. Install Twrp or Orangefox recovery (download it from somewhere)
4. Enter into recovery and install small firmware FIRST, dont reboot, install big firmware (recovery version) SECOND
5. do not reboot
6. format data
7. Now reboot into fastboot
8. Extract fastboot firmware zip into new folder on desktop
9. Start Mi flash, select that folder where u extracted files and tick "clean only" on the bottom of the Mi flash if u want to leave bootloader unlocked and from drop down menu near that pick "flash_all.bat".
Thats how i did it.

Hello all,
It's a long time that's i haven't post a thread here but i have a question.I have a Poco with MIUI Global 9.6 Stable (9.6.25.0) for ROM with a Android Version 8.1.0 OPM 171019.011 with root acces, unlocking bootloader and TWRP 3.3.0-0 installed.
I would upgrade my phone to something "newer" (A ROM with Android 12 if possible) and conserv the root access and my apps.
I have read that now ,we should have 3 files to do that (firmware,system and vendor) to make a wipe and install new ROM with TWRP.
So my question:
-Is it possible to upgrade Android 8.1.0 to Android 12 witn a new ROM? (i have read something about kernel in Android12 but haven't understand all)
-Have i missed some steps or just download files,boot TWRP,wipe and install newer ROM+firmware and vendor appropriate is good?
-Which ROM do you recommend?
Thanks for the previous answers.

It's not possible to switch from stock ROM to custom without doing clean install. You will have to root again.
First update to latest Official Stock ROM, then take backup of your files to your PC or to SDCard (if you have one) , flash to latest Official TWRP and check my POCO F1 Ultimate Collection & Guides. You can find everything there. I have awarded recommended ROMs in my collection.
Feel free to ask if you have any question regarding the guides.
Thanks for the answer.I have begin to read your guides.
If i understand good,it's not possible to conserv my root,unlock bootloader and twrp when i upgrade to android 12? Automaticaly i should root again my phone and restore with titanium backup my files,contact,....?

First you need to take backup of your files to PC or External SDCard.
Then you should update to latest version of MIUI via OTA if it's possible or via TWRP (you can use the stock recovery rom to do it via twrp). (You can also use my guides for clean install stock rom)
Then you should unlock your bootloader if it's not already unlocked.
Then flash latest Official TWRP.
Then flash latest firmware (not vendor) just to make sure you are on the latest. (You should be on latest firmware after updating to the latest MIUI version)
Then Wipe everything + format data according to my guides and flash the ROM you want. If you choose A12 Pixel Experience or crDroid keep in mind that these ROMs use their own recovery because these are encrypted by default ROMs and TWRP can't handle the decryption of A12 encrypted ROMs yet. So to make OTA updates and that stuff work correctly devs of these ROMs decide to use their own recovery which can handle the decryption of encrypted roms and as result to make OTA update work fine. Check the installation instructions of these roms in their threads. (Afterwards you can use adb sideload to flash stuff using these recoveries)
After that, flash Magisk since you want root.
Then you can restore titanium backup if you want.
OK i follow your instruction.Thanks
Hello retrial,
I have now updating my phone to MIUI Global 12.0.3 Stable with Android Version 10QKQ1.My phone is not yet rooted and now he is encrypted.The recovery is now Mi-Recovery 3.0
I have unlock again my bootloader.
Now to follow your instruction,i should flash the latest TWRP.
I have take TWRP-3.6.0_9-0-berylium in your guide.
I think i should do Fastboot Method because i'm now in Mi-Recovery?i'm right?
No problem with the encryption?
Thanks.
i have find this video.This is not the good phone but i think that the installation is the same:

Yes use Fastboot Method to flash TWRP. No problem with encryption.
After that follow my clean install custom rom guide to flash the ROM you want. Also please check the instructions in the threads of ROMs you want to flash. A12 crDroid and PE use their own recoveries.
Basically tell me which ROM you want to flash to help you exactly with steps.
Hello retrial,
i have a problem to install TWRP-3.6.0-9-0 on my pocophone.Everything working fine but in step 8 of your guide,i can't find my twrp.img that i have copied in 2 different case to test :
8. Boot into Recovery by typing in cmd: fastboot boot <recovery_filename>.img (The file may not be named identically to what stands in this command, so adjust accordingly and write the full path of it, check the example below).
This command will not flash permantly the recovery, it will just temporary boot into it and afterwards you will flash permantly the twrp.img you copied into your Internal Storage or SDcard in recovery partition.
For example: fastboot boot C:\Users\Retrial\Desktop\twrp-3.5.2_9-0-beryllium.img
Have you an idea to why i cannot find my twrp.img in the boot mode?

I have all the steps on my guide. Please read it carefully. It boots back to mi recovery because you haven't flash TWRP yet just booted into. After boot into TWRP u need to flash twrp in recovery section so it will stay after reboot.
Please read the steps.
Download portable Minimal ADB and Fastboot and latest Official TWRP recovery.
Open cmd from minimal adb and fastboot and write:
fastboot boot and the path you have TWRP.
Example:
Code:
fastboot boot C:\Users\Retrial\Desktop\twrp-3.6.0_9-0-beryllium.img
Then proceed with the rest steps in my guide. Connect ur device to pc while u are booted into TWRP and copy TWRP.img to your device. Then in TWRP press Install Image and select the twrp.img u just copied into ur device. Select recovery and done.
I have made a video to show you what happened (sorry for the bad quality and the moove) :
I think a video is easyest to understand my problem.For information my bootloader is unlock and usb debugging ok.

Hmm strange, probably of MIUI. Anyway since you are going to flash custom rom, when u flash twrp in recovery go back and select wipe and wipe everything (read my clean install guide), go back press format data type yes, and then reboot to TWRP.
EDIT: I just saw u rebooted to system. That's not what we want. Press reboot to recovery.
i reboot first to bootloader after have flash the twrp.img in recovery.That's only the second time that i reboot to system to use the normal mode of the phone and reboot after to recovery mode to show you that mi recovery is back.

The TWRP flashed correctly. You overlap it again by pressing reboot to recovery from MIUI updater.
Don't do that...do the combination to boot to TWRP after flashing it. Power+Volume Up.
And continue with clean install steps in my guide to flash custom rom.
In my guide I write nowhere to boot to MIUI and press from MIUI Updater reboot to recovery, please stick to my guide and you will be fine.
