Boot loop after trying to root. - Xperia Z4 Tablet Q&A, Help & Troubleshooting

I followed the instructions here: https://theunlockr.com/2015/09/19/how-to-root-the-sony-xperia-z4-tablet/
I unlocked the bootloader, flashed the new boot.img, then rebooted.
It now keeps going to the sony logo then restarting over and over.
Please help!

I got out of the boot loop by installing version 43 from here: https://drive.google.com/drive/folders/0B0j3VJ1Xp5N8cnhQamtxRWVtRmc
But now I'm still not rooted

AndroPlus kernel is not up to date anymore.
AndroPlus kernel is NOT rooted.
You need to flash SuperSu or Magisk (did not try M.) after flashing a custom kernel.
The flawed documentation also left out the installation of a recovery necessary for this.

Im able to flash TWRP and boot into it but then I have to re-flash the boot.img to get back into android.
It seems I cant have TWRP and boot.img working at the same time.
I just looked at the guide in your footer, I'm guessing I lost my TA partion
There was no mention of that on sonys bootloader unlock info page.

I finally got it.
To get into recovery I had to use the command: fastboot boot TWRP-3.1.1-lineageos-karin-20170520.img
I was then able to install superSU

I really do not know why they do not mention and link my [Guide].

And the guide I read on flashing the recovery said to use this command: fastboot flash boot TWRP-3.1.1-lineageos-karin-20170520.img
That was flashing the recovery to the boot partition!
The same guide said to hold both vol+ and vol- to boot into recovery, that's why I was having such a hard time.

HELP! Soft Bricked HTC One S!

I'm not new to flashing custom roms and rooting Android devices, so I don't think I'm a noob at this. I decided to help my friend unleash the power in his HTC One S by rooting it and giving it a custom recovery, I went through the right processes, Unlocked the phone's bootloader, and flashed the superuser zip and the twrp image, as it didn't seem like a clockworkmod image was compatible with the phone.
I then booted into recovery, wiped/factory reset and then flashed the latest CM11 nightly and got an error in TWRP recovery about the bootloader not been interoperable something like "
Code:
2.15==2.13"
in the error message , fine, I rebooted back into fastboot and checked the HBOOT Version and found out the phone was on HBOOT 1.13 and I think CM11 requires the most recent HBOOT version to work on HTC devices. The phone has got S-Off though.
Now I'm stuck in a bootloop cause I already wiped the OS in TWRP, I have everything in place, the right drivers and all that, I also tried re-installing the stock rom by downloading an HTC One S's RUU file but the device wasn't recognized at all by the RUU installer, I also tried to flash a stock 4.0.x rom as a zip file, no Joy. Now the phone is stuck at the point where it doesn't have an OS to boot into at all.
I'll really appreciate the community's support helping me fix this issue.

You need that. Luckily you're already S-Off, so shouldn't be terrible to get going again. Just update the firmware, reinstall TWRP and re-flash CM11. Should be good to go afterwards.

Thank you so much for the reply, does it matter that I don't have an OS to boot into as I already wiped and factory reset the phone for installation of a new rom.?

Nah, shouldn't. The firmware we're referring to here is independent of the OS.

Since you are S-Off, needing fastboot to install the boot.img is not necessary. It will install through recovery.
But, for future reference, you would boot to the bootloader screen, select fastboot, then assuming you have fastboot set up on the PC and the boot.img in the directory of said fastboot, you would use this command:
fastboot flash boot boot.img
then
fastboot reboot

I tried flashing the firmware.zip file from the thread but I got a FAILED: (remote: not allowed) error in command prompt at the end of the process, what did I do wrong?
UPDATE: I was able to update the bootloader version successfully, as I forgot the part where I was to boot into RUU mode with fastboot oem rebootRUU and worked perfectly the second time.
I rebooted and found out the boot loader was updated to HBoot 2.15, and I also updated twrp to the latest S4 version but now in recovery I get errors about twrp been unable to mount the /data partition. Do I flash another recovery image?
UPDATE:
Thank you so much es0tericcha0s, I really appreciate the support, I got the /data mount issue fixed finally. I just had to flash an older twrp recovery image and then reflashed the new one in fastboot and I could then flash CM successfully.
I can't believe I finally unbricked this phone, its been bricked since Sunday. Once again, es0tericcha0s, Thank you!

You might need to RUU back then. If you have issues with the RUU exe, then you can extract the rom.zip and install it like you did the firmware. There are quite a few tutorials on how to extract it, or there might already be a version floating around for your phone.

[Q] Stuck On Sony Screen

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.

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.

Can't get onto latest TWRP

So I am stuck on TWRP 2.7.1.0 and i am running slimrom 4.4.4 on a c6833 and the reason for this is because it's the only thing that will boot on my phone. There was some intense trial and error a few months ago and a few days with a bricked phone but I finally got it running again, and I am nervous about messing things up again.
I am wanting to move to a more up to date ROM either scrubber port 5.1 or remix 5.1.1, but they both ask for updated TWRP to install. And I can't update TWRP using the TWRP tool from the store. It downloads but when it tries to install it says there is a problem. Previously, trying to update TWRP would result in SONY bootloops. I was about to try the dd method but just wanted to make sure it was safe.
I am a bit of an idiot (I got rid of my encrypted keys on day 2 of owning the phone) so any help would be appreciated.
Thanks!

The easiest way is to use Rashr. It should set everything up automatically. You may then reboot to recovery from the ROM, or by holding Vol- when the LED turns purple on boot-up.
If that doesn't work, for whatever reason, try dd or Flashtool. Using Flashtool, you can flash openrecovery-twrp-2.8.5.0-togari.img with the phone in Fastboot mode.
Let me know if you have any further questions!
Used Rashr...and now I can't get into recovery. I can still boot into my phone, but booting into recovery just fails with a yellow LED?
So Rashr still says I have 2.7.1.0 installed. :/

Alright, you likely need a newer kernel first. Using Flashtool, you can flash this boot.img (newest AICP kernel) to the boot partition using the Fastboot mode (or use fastboot manually from the Flashtool/x10flasher_lib folder with "fastboot flash boot boot.img"). At this moment, you'll no longer be able to boot into the ROM, so make sure you've done all necessary backups and are ready to install a newer ROM. Then use Flashtool/Fastboot to flash the openrecovery-twrp-2.8.5.0-togari.img file to your recovery/FOTAKernel partition ("fastboot flash recovery openrecovery-twrp-2.8.5.0-togari.img"). You should be able to enter recovery now.
Awesome thanks! Will I need to do this each time I flash a ROM? Or can I just jump from something like scrubber to something else?
I know this is an old thread but is that the boot image I need to run TWRP 3? If so, can I do this via dd?

Don't use install img option on twrp it may not work always
Instead of that you can flash recovery using fastboot with "fastboot flash recovery (the name of recovery).img) command

Note that the Z2, like most other Sony devices does not have a proper bootable recovery. As such you have to install a kernel that includes a recovery with it. For a time I will try to continue to supply updated stock kernels repacked with TWRP in them. If you are running one of my kernels or have a custom ROM like OmniROM installed, you can install TWRP in the FOTAKernel partition to stay on the latest version of TWRP.

To install a stock kernel, boot the device into fastboot mode and then from your computer: fastboot flash boot path/to/filename.img

However is it true? With latest updates there was bootloader update which brings (or at least should as Sony said) /recovery partition (or more gives access to it, coz partitions was probably always there).
However how it exactly works? I always thought that onee flashed update with newest bootloader will leave new bootloader and this partition forever. But I got Z2 with .291, downgraded it to 4.4.2 for Root and TA backup and than tried to flash recovery to recovery partition, but got error: FAILED (data transfer failure (Unknown error)).
Does it mean that only on latest update(s) there is possibility to use this partition?
Never tried it on my ZU before. I just started form latest 5.1.1.
EDIT: OK, so what i assumed was right - on 6.0.1 I was able to flash the recovery to it's partition.
Now the problem is with booting into it. How? With Power + Vol- it still stright to boots to OS...
EDIT2: adb reboot recovery boots to different bootloader screen (Power+Vol- gives SONY screen and adb gives SONY + XPERIA screen.
However it still boots strght to Android...
Any idea what I'm doing wrong? I have 23.5.A.1.291 + unlocked bootloader + TWRP 3.0.2-0 (official) flashed with fastboot flash recovery img.
I'm 100% sure that SONY screen (w/o XPERIA) is the right one as I have identical one on my ZU when booting into bootloader-recovery mode. But why here it don't boot TWRP, but OS?
HELPPPP
Pleaseeeee tell me how did you flash twrp 3.0? I have tried almost everything it now seems impossible for me... Pleaseee helpp me T_T ... Thankk youuu

Ignore the scary bootloader unlock warning. That's not preventing you from booting to TWRP.
What's preventing you from booting to TWRP is you didn't fully install TWRP and activate it. You still have stock recovery because you flashed TWRP but didn't finish the TWRP installation/activation process. So TWRP didn't stick and you have stock recovery still.
Read the instructions again. Post #193 of the WTF bootloader unlock and root thread.
WHICH instructions did you follow? Because with my instructions I cleary tell how to immediately boot to TWRP with fastboot flash commands after installing it -- and to NOT do any anything else (even rebooting the phone) before finishing TWRP installation and activation. You either didn't use my instructions or didn't carefully follow them?
People should really PRINT out the instructions before starting the process so they can carefully read it. It's very easy to skip over an important part or skip over a part you don't think is important?
It's all there for a reason.

What's preventing you from booting to TWRP is you didn't fully install TWRP and activate it. You still have stock recovery because you flashed TWRP but didn't finish the installation process. So TWRP didn't stick and you have stock recovery still.
Read the instructions again. Post #193 of the WTF bootloader unlock and root thread.

I have installed using fastboot command and used the boot twrp.img command, the corruption message shows then the screen goes blank and it goes from the lg v30 logo back to corruption logo then reboots. What stage have I missed.

From my instructions:
TLDR:
flash twrp: fastboot flash TWRP.img (TWRP-3.2.1-joan-v0.1.img re-named as just "TWRP.img")
boot twrp: fastboot boot TWRP.img (TWRP-3.2.1-joan-v0.1.img re-named as just "TWRP.img")
swipe to allow modifications (do NOT leave read-only, TWRP NEEDS to be able to make changes to your system.)
select WIPE, then FORMAT DATA, then write yes
wipe cache, dalvik, data
flash magisk
flash encryption disabler
flash root disabler
reboot
STRONG SUGGESTION: After successfully doing all this, when you finally boot back to LG Oreo, install an app like this to easily facilliate rebooting to TWRP recovery in the future: Recovery Reboot
Even if you didn't actually install TWRP, you would still be able to boot to TWRP using the boot command ( fastboot boot TWRP.img) as long as you were connected to your computer and had TWRP.img in your ADB folder.
I've done it to make TWRP backups of "stock" systems where TWRP is not installed on purpose.
People who never finished activating TWRP have been able to do it, as they really don't have TWRP installed --- they are booting to "temporary" TWRP from their computer using fastboot boot TWRP.img. If they try to boot to TWRP from their phone, using an app they get the Android on his back which is a clue they REALLY don't have TWRP installed... but they are still able to fastboot boot TWRP.img when connected from their computer.
If you can't do that, something is very wrong. It's just that's the easiest way to get into TWRP after flashing it, so you can then "activate" it, make the installation stick.
Thanks for that its installed and I have installed a rom however I still cant boot into recovery, I have to reflash to get back in, and is there any way to get rid of the corruption message

Not really. The "corruption message" is just LG's scary bootloader unlock warning to discourage you from rooting your phone. It's really a sign of freedom. Ignore it.
It's going to show up when you boot to TWRP or even when to boot to regular OS. It's just an image, a picture for LG to try to scare you. It stays up a few seconds then goes away.
Some Verizon users have found if they flash part of the Verizon firmware back it replaces the bootloader unlock warning with a few seconds of black:

I did have to wipe to reflash US998. But while I was fighting that I discovered what partition holds the bootloader warning!!!! It's rawresources. I moved the VS996 rawresources over to my US998 /dev/block/bootdevice/by-name/ and no longer have the warning. Granted it's a short black screen pause,

While that is very interesting, for now I would just ignore the warning. It's not preventing you from booting to TWRP. What's preventing you from booting to TWRP is somehow you haven't finished the entire TWRP installation/activation process.

If you installed the Recovery Reboot app I recommended (requires root access) you can boot to TWRP from there on your phone, IF you REALLY have TWRP installed. If you are having to boot to "temp" TWRP via ADB from your computer every time, then TWRP is not really installed on your phone. If you use that Recovery Reboot app, and it boots to Android on his back, then you still have stock recovery installed.
You need to reflash (reinstall) TWRP, then boot to TWRP immediately and go through the steps I posted to make it writable -- so it will stick as your custom recovery.
RTFM Myself
