I was thinking about returning my Xperia Tablet Z for various reasons, but I am not sure I can because I have rooted the tablet and have uninstalled preloaded apps (whih I did not back up). I know that I can unroot the tablet and do a "factory restore," but will that truley make the tablet "like new?" Will it restore the apps that I deleted? This is my first tablet and I am a little confused the proper steps to returning this tablet to normal.

If you only rooted and did not unlock boot loader, then use Sony Mobile's Update Service software to reinstall factory stock firmware and the tablet will be like it just came out of the box.
Thanks. Sounds easy. One thing: I'm too sure about boot loader. I used "DooMLoRD_Easy-Rooting-Toolkit_v17_perf-event-exploit" to root the device and it seemed to do everything in one step. It wouldn't have unlocked boot loader on its own right?

Correct, DooMLoRD's rooting tool does not unlock the boot loader.

I found the following post while doing my daily read thru all the other forums and some people are saying that it has rescued them from wrong TWRP flash and Unrecoverable Bootloader errors.
I would try to do all the other methods available first but if you are completely bricked then you have nothing to lose.

Flumpster, I was going to start a separate thread to take my brick issues out of your dev thread and saw your thread here. So the option here is to reboot into fastboot, basically wipe everything and then flash the system blob from a stock ROM.
My main question is what if the person is on a TF300T bootloader, in my case 10.6.1.8. Would flashing the latest stock Asus JB ROM over 'system' for the TF200 replace the bootloader as well?

To answer myself, yes it does replace the bootloader. The latest ROM on Asus (from last Dec 2012) installs bootloader 1.00e ww_epad-10.4.2.18-20121122 a03
I installed stock TWRP 2.5.0 here for JB based on this thread and was able to get into TWRP and install the Hairybean Upgrade for 2.3, followed by the HB 2.3, and am now booting into the ROM. W00t! Great link in the OP flumpster.

adb reboot bootloader
When in recovery.
I just got a used prime and was trying to root/unlock/custom recovery/rom but I think I did something wrong.
This process seems a lot more delicate and volatile than my phone
I installed cwm through the CWM Rom Manager app after unlocking and rooting both of which went smoothly and device booted, and the device was properly rooted. After flashing recovery through CWM Rom Manager app I am ASUS boot screen
The one with "the device is unlocked" in the upper right corner and just sits in that state indefinitely. Can't do anything other than restart and get back to that screen. Any ideas?

Unfortunately you never read up on anything before attempting it. There are warnings everywhere on this forum saying not to use cwm on the prime and not to use rom manager and goo manager.
The last official version of cwm on the prime was for the ICS bootloader and if you flash that recovery onto jellybean bootloader then chances are you are going to brick yourself. Rom manager doesn't check what you are on and just installs the ICS version anyway. I reported this to Koush 2 years ago and he did nothing about it.
If you can't get to the bootloader or recovery by holding down volume down and power the same time and you also don't have nvflash backups then I am afraid that you are hard bricked.
There are only 2 options. Either pay Asus to fix it which will cost you more than you paid for it or you buy a motherboard off ebay or one with a smashed screen but still working and swap the motherboard out.
hypocritelecteur said:
Drat. Is there absolutely no chance, no method that might possibly work? No system dumps or backups or anything I can snag from another user to bootstrap my way back to functionality? I admit I jumped the gun here defs. I've been mucking with roms and hacks for android for years and never hard bricked anything and never run into a system this volatile. Didn't realize I was even being reckless! Just a different world I guess. This is however my first tab--are they in general more risky?

I know how you feel mate as before getting this tablet I have had numerous android devices and have had lots since and this is by far the easiest to hard brick. With other devices you can mess up but normally there is a method back in (odin etc) but Asus decided to tie it down completely.
The nvflash guys did a great job to make our devices brick proof but you have to make sure that you have your backups first. No one elses backups can be used. They are specific to your motherboard.
You can pick up motherboards quite cheap on ebay and someone here on one of the recent posts even put a tf300 motherboard in there instead as it was a lot cheaper ($50). They are basically the same machines anyway.
Was it unlocked when you got it ? If it was ask the original owner if he ever made nvflash backups.
tf201 maybe bricked

When in TWRP you should have adb access if you have the drivers installed.
Try.
Code:
adb reboot bootloader
to get you back to fastboot.
I managed to install original system blob. But what now? After start I have again four options, but my Prime is not booting into system or recovery. It always hang up on starting screen with ASUS logo or wit a dead robot.
Thank you.
---------- Post added at 09:05 PM ---------- Previous post was at 08:06 PM ----------
ok, now I am totally bricked, I restarted my Prime and it is black, even backlight is dead. It only reacts to power button, when I hold it, it vibrates after a while.
Fastboot or ADB cannot contol it.
Dammit
Did you ever manage to get your system back?
I used ADB to make a backup of my TF201.
I couldn't get ROM manager to flash a new ROM - every time RM restarted the TF201 I simply got the screen The Device is UnLocked together with the graphical menu for Recovery, Android, USB and Wipe and it just sat there and did nothing.
Eventually, I pushed the CWM ZIP into /SDCARD/ renamed it to UPDATE.ZIP then tried rebooting to see if it would treat that like an OTA update - it didn't.
So then I chose the Wipe option. It sat there for ages with nothing happening.
So I then rebooted - now I get the The Device is Unlocked in the top left hand corner, the ASUS logo in the middle and the Powered by NVIDIA`TEGRA` in the bottom right but it does not boot - it is bricked!
My PC no longer sees it in ADB or FASTBOOT so I can't either flash something or restore my carefully taken backup.
It won't boot into anything other than the screen above - so the key combination for Fastboot doesn't work any more.
Prior to all this it was running stock 4.1.1 but was successfully rooted and had been like that for quite some time.
Any ideas?
Kind Regards

Hi Steve:
Well darn it, I'm another one with a completely bricked tf201. Without going into how I got there, I have the same situation as you... with "The Device is Unlocked" in the upper-left of the screen, "ASUS" in the center and "Powered by Tegra" in the lower right. If I boot with either just the power button, or the power botton and volume down, I get the affore-mentioned screen.
If I boot with power button and volume up, I get a completely black screen. I was very interested in whether you received a reply to your question?
I've noticed that the greater percentage of these questions, as I've described my system, remain unanswered. Not that I am complaining, but I am certainly interested in whether or not there is a remedy as of this date? I am not able to afford sending my tablet to ASUS, so would really appreciate any work arounds I could try.
Cheers man. Hope to hear from you.
Jim
Hello Guys,
Just wanted to check there is any official method to reload LG D802 boot loader which will remove the signature "ROOTED" in recovery mode. This will help to retain the warranty in case of any hardware failures like speaker, cam etc. Just wanted to know if any method is available
Thanks

Hey, thanks for the great guide! But this doesn't reload the recovery loader. I tried this method and I'm easily able to revert to stock but the recovery loader is triggered as ROOTED and this will kill the warranty. (I'm not soo bothered about the warranty of the software but it matters about hardware. Who knows tomorrow)
Big thanks if we would find a solution for this.
Thanks.
I ran across a thread somewhere where it was mentioned that you have to reload it twice.
http://forum.xda-developers.com/showpost.php?p=48754417&postcount=9
Sounds like a plan.... first flash would be removing custom like removing root access....and second flash was like racking the device that the device is not rooted and reloading the boot loader itself and resetting the trigger...truly sounds like a plan.... I will try this method....

I have a Sony Xperia Tablet Z, 64GB WiFi (SPG312) running stock 4.3, and I can not root this thing. I've tried several different methods to no avail. Does anyone on here know how to root this thing? I'm ultimately trying to install CM11.
Either go back to 4.2, root with Doom's Rootkit, then install a recovery, and install 4.3 already rooted, or unlock your bootloader, install CM kernel, use the recovery built in to install the SuperUser zip, then flash stock kernel again.

So unlock the bootloader? How do I go about that? And after that I can install CM right from there? That sounds like the one thing I haven't tried.
How do I go about doing that?
http://unlockbootloader.sonymobile.com
Follow that link. It's pretty easy. Just make sure you have all the tools in hand. Shouldn't take more than a hour to read everything and do the procedure, if you have everything ready.
It's mentioned there, but remember that it will void your warranty and, with Android 4.3 or lower, on stock ROMs, you will not have Bravia Engine working. Also, in any version, Music and Video Unlimited will not work anymore.
Another big tip: Go to the Xperia Z section (the phone one), and on the sub categories, can enter one called Cross Device Development, or something along those lines, and look for a thread with the name TA backup. If you do the long process, of going back and such, backup your keys. Should come in handy in the future.

u need to download flashtool and find a 4.1.2 rom for your device...
then you can either use framaroot 1.91(gandalf exploit) or use doomlords root setup...
after that you can install phill'z recovery...
http://forum.xda-developers.com/showthread.php?t=928343 this link was very help full for my device sgp311 and i think its almost the same for your device only the rom and the stripped .ftf will be different...
unlocking your boatloader is not really applied to you,you only need it if you want to install custom roms...but before you do search a bit around to find hou you can backup your drm keys aka .ta partition.
Make sure you downgrade to 4.2 and root using http://nut.xperia-files.com/?dlid=V...jb3ZlcnkyLjcuMTIzLUJFVEEuaW5zdGFsbGVyLnppcA== option 3 then backup your TA partition before unlocking your bootloader, or theoretically you'll lose warranty
ok ok ok
So what steps do I take to install CM11?
Which method posted would get me there? You guys are saying a lot of different things here, have me a little confused

Unlock bootloader > flash any cm10-11 kernel that has recovery built in > boot to recovery > flash SuperSU > flash 4.4.2 stock kernel back (from FTF)
So I've unlocked the bootloader (lost DRM keys :/) and flashed the UK version for my device to enable fingerprint. Now I want to root it so I can speed my phone up and save battery life. I've looked at the guides, and people said I needed to install TWRP in order to root. I'm not familiar with the rooting process, and I can't afford for my phone to be bricked. People who followed the guides had their phone stuck on the boot logo, and I want to know if there's a secure way in rooting my Xperia X.
Hello. I followed the process in this thread:
Root Xperia X (F5121,F5122) {N} 34.3.A.0.252-6dec2017
I don't think anyone would tell you that there's truly a "secure" way to root your phone (by which I'm assuming you mean zero chance of bricking), but the methods described in the post are pretty robust, and even if you get stuck at a boot screen, you should be able to revert back to stock by using flashtool with the phone in flash mode. I used that process to recovery from failed experiments several times.
I have owned my xperia x compact since June 2017, the first thing I did with it when I bought it was flash the UK firmware and root it. The phone has operated with out any real issues since then, but today I woke up to my phone on the charger showing a back lit black screen. It was unresponsive to any inputs so I rebooted it (power button, up volume), and it would just load to the xperia splash screen freeze then reboot ad nauseam. I am tempted to use the xperia companion to attempt a software repair but I am afriad if I do I'll get updated to oreo and not have a working camera. I did back up my keys when I rooted my phone but I did not change to the bootloader from factory.
Any input as to how I should proceed would be greatly apprechiated
Thank you
Do you have twrp? Do you have a twrp backup? If so, just boot to twrp, try factory reset, and if it boots after that, just restore your backup. If you don't have a backup, and you don't want to lose data, it's hard to know what to do, especially since you don't seem to have a clue what caused it. You can try to flash an ftf with Flashtool, excluding everything except 'system', (and making sure to check nothing in 'wipe' box'. Other possibilities, if you have recovery, is to try uninstalling things like Xposed, Magisk, Substratum, etc...
Thanks for the input, as stated I never changed the boot loader so unfortunately I do not have twrp and thus no images to restore.
I would like to preserve my data if possible but biggest concern is losing the camera. From what I gather using the Xperia companion will update my phone to Oreo likely loosing my ability to root but also locking out the camera. I have a back up of my DRM keys but if I am not on the factory marshmallow rom I don't think I'll be able to restore them. So is there a way to restore the phone to original factory marshmallow firmware?
Marshmallow ftf / Flashtool. I'm sure you can find one out there. Also, you can upgrade to O and your camera will be fine. Drm keys just make it a little better. And you can root with Rootkernel, and use your ta backup to mount onto Rootkernel, so camera will be just like stock. See here - https://forum.xda-developers.com/x-compact/how-to/stock-8-0-root-recovery-t3747479
Thanks for your help I really appreciate it. If I can have camera and root functionality on Oreo then I might as well upgrade.
Its been awhile since I've messed with this, and I am on a different computer. Hopefully I can get this phone up and running and out of this boot loop.
Also looking at your guide the modded boot images offered are older than the firmware currently offered on xperiafirm, do I need to find the specific firmware offered in your guide instead of the one offered on xperiafirm?
It's pretty easy to do once you're set up, but I'll see if I can post an updated one tonight.
Thanks, I do not recall having much issue getting the device unlocked and rooted with the guides here on XDA. Then again the phone was fully bootable at that time so once plugged in, windows and the xperia companion took care of the drivers. I am in the process of familiarizing myself with all the ancillary bits which may not be explicitly detailed. I suspect I will need to put adb and fastboot on this new PC, was going to use snoop05 15 second installer but all his links are dead.
