[Q] Getting ready to flash TFT, some questions - Xperia Z2 Tablet Q&A, Help & Troubleshooting

My Xperia Z2 LTE Tablet is fully unrooted with the TA.img successfully created and backed up with all user and system apps backed up with Titanium Backup. The tablet is Verizon branded and would like to flash an unbranded TFT, but had a few questions before I proceed just to make sure I don't do anything wrong.
1.) Is a Titanium Backup of apps enough, or is there some other type of backup I should be making?
2.) If I use this image, which is for SGP521, will it work with my SGP561?
https://docs.google.com/file/d/0B4o8Tp4omHzWazhDUGxEYjJwUTQ/edit
3.) Will my DRM keys remain intact if I flash it with this method:
http://www.xperiablog.net/2014/06/01/debrand-your-xperia-z2-tutorial/
Or, alternatively, will I have to unlock the boot loader first and then restore the DRM keys after?
4.) Will there be any problems with using the DRM keys on a different TFT image, or are they only tied to the physical hardware?
5.) What would happen if I performed a factory reset after flashing a new TFT image?
6.) If I restore my apps after flashing can Titanium Backup use a Snapshot image and change the ID of the device to match the apps without any problems, are are there some limitations?
7.) Is there anything else I should read or do before I proceed?
Thanks.
EDIT: So according to Sony, some Z2 tablets cannot be unlocked. I followed the steps to find out and it says unlocking the bootloder is not allowed. If an unlocked bootloader is required to unbrand my tablet is there an unofficial way to do it?

EDIT 2: And it looks like I can't use the Sony PC Companion
"Sorry, it's not possible to update your device using Sony PC Companion.
Please use the Verizon Upgrade Assistant tool"
And the Verizon Upgrade Assistant tool doesn't recognize it!
Ugh.

Lost stock recovery on ACER B3-20 after failed update (rooted)

Hi,
I own an Acer B3-20 tablet with stock firmware, rooted via kingroot and unkingrooted with supersu me pro.
An OTA update came today for my tablet and I did proceed not thinking about the root thing.
The update failed with the file
Code:
/usr/bin/debugd64
found not equal to the one expected. I assume it is the rooting process that changed that file.
No damage was done when I rebooted. All was there.
So I said to me. I am gonna reflash (OS_Acer_AV0L0.B3-A20.RV03RC06.WW.GEN1_A51L_A.zip) the stock firmware from SD Card to get rid of root but when I got into recovery mode (power+ vol up) I discovered that menu in chinese instead of stock recovery. OMG!

Edit: looks a lot like this
I tried again the update after deactivating super su. (unrooting ?). It failed to do the update again but drop me it what seems to be exactly the stock recovery. So I used it to reflash the original firmware provided by Acer for the tablet. hence unrooting completly. and proceed to make the update again which worked this time. :silly:
Did you get the new chinese recovery after the update ? my build is now: Acer_AVOLO_B3-20_RV07RC01_WW_GEN1
How did I get the original stock recovery given I have already reflashed the original firmware and did not get it back (but I applied the OTA update on top of it) ?
What does every line of it mean ? Can somebody translate this menu, please ? the last one is reboot . It's all I manage to get
first highlited line seems some low level stuff and all this does not seem to be the recovery in chinese.
Thanks

New revision for X96 Max

Hello!
I encountered a problem with tv box X96 Max 4/32. I bought a tv box in July in a store VONTAR. The tv box came in a new revision, all old firmwares are not install and not work on it . If the firmware passes the installation, the TV box turns into a brick, and you need to close the contacts to flash another firmware. My tv box works on only one stock firmware X96Max_V311_20190625, but Bluetooth doesn't work on it.
On new revisions tv box have firmware X96Max_V31R_20190716_2201, can anyone get it for flash via UBT (img format).

TWRP multiple errors trying to flash a ROM on a bricked Huawei

I can not find a way to avoid errors in the flash process or wipe process, I attach some of the different errors that I get, the last image is the last error.

a bit of context and history of the things I did:
This is an Honor 8 FRD-AL00 from China, in 2017 I unlocked the bootloader, I rebrand the phone into its Europe version FRD-AL09, then I updated to Emu5, then in my first vacation on Europe (I am from Argentina), the phone ask me for an update. As I knew that I used an Europe ROM, full rebrand, I did not saw nothing nothing wrong with that (if I wanted an update on Argentina, I have to forced), so I accept the official update there.
Results: I bricked.
I buy a new phone there, I kinda forget over some years, now I want to fix it, but seem that it is quite hard.
First I had problems installing TWRP, the only way was using the Multi-Tool8 from @teammT flashing the TWRP 3.1.1 as Erecovery.
I tried to do flash a ROM from a similar year than my last correct update, fail using commands, fail using the tool, fail using an extra SD on dload, fail using TWRP.
I tried the same thing with the stock firmware for FRD-AL09 (the multi-tool8 always recognize the phone as FRD-AL09, until I made a full wipe with TWRP of cust, system, vendor, etc).
I tried to format system or other partitions as FAT and Ext4, but nothing happen.
The errors continue when I try to flash the ROM.
I even had a backup made with TWRP when the phone was working fine, I tried to restore that backup with TWRP and I receive error.
What can I do to save the phone?

Question (solved) Cannot install a custom ROM

Hello everyone, a week ago I received my Mi 11 Lite 5G and the first thing I did was unlock the bootloader. Today I managed to unlock it and tried to install a custom ROM (xiaomi.eu). However, I had a problem that made the operation impossible. I forgot to activate the option "install via USB" thinking that this one was not important, obviously I underestimated it. My question is: do you have any solution to reinstall the basic ROM (there isn't system currently), or activate this option other than in the phone (in fastboot with adb for example...), regardless of the method, I hope there is at least one.
Awaiting a positive response (I hope), greetings and I wish you all a merry Christmas.​
This option doesn't really matter, if your bootloader is unlocked (as in there is a undone lock icon every boot above the Mi logo) just go into fastboot by shutting the phone off forcefully, then holding down Power + Volume Down until you see the Fastboot Screen as shown below

}
Then after that, check device manager in Windows to see if your device is being seen as "Android Bootloader Interface", if it is. Then you're good to go! Download the latest Xiaomi.eu ROM for Renoir then unzip it, then run the batch script for your case. You will lose all of the data on your phone's internal storage when installing though. So beware and be sure to make backups!
