Thanks for helping, But how can i choose a file in Flashtool ?
As i understand i can only choose the FTF file , And i chose the Xperia Play one.

OK, After a lot of searching i found out that i had my phone Bootloader Unlocked before flashing,
And after that i tried to flash it and i got the error and it wont boot.
From what i red i only have 2 things to do :
1- Get the phone booting but without radio.
2- give it to sony and tell them that it just crashed while i was updating it.(And don't tell them anything about to root or the bootloadr)
So please if anyone knows any better way to fix it please tell me.

You didnt need to unlock you bootloader to use flashtool, but now you have just flash a system.img from fastboot, your phone isnt bricked unless you tried to do an OTA updated with an unlocked bootloader

Try formatting /system and /boot first,
In fastboot type in
fastboot erase system
fastboot erase boot
Then flash this kernel with the command "fastboot flash boot boot.img"
http://forum.xda-developers.com/showthread.php?t=1176502
finally flash this system image with command "fastboot flash system xxxxxx.img"

Yes i just checked and it's unlocke.
And thank you so much for helping and i will PM him and wait .

Finally i got it to work !
I deleted the system with fastboot , Than i used this tool :http://forum.xda-developers.com/showthread.php?t=1134334 to re-lock the bootloader.
And finally i used the SE PC programme to repair the phone with the latest Update.
Thank you AndroHero very much for helping me.

You could use KDZ updater and flash a stock ROM. Could you explain the problem more in detail please?

i think the best way is to flash a 2.1 rom thru fastboot im sure there is fastboot stock rom somewhere after that use mur4ik's custom bootloader builder to erase fastboot and recovery.

thanks!!!
but i was told from someone that if you
do it that way the phone wont turn on
in some cases!

I recommend you that you must be sure that this downgrade would be effect, beecause when you flash your device, the memory is modificated and its too hard to unmake this canges....
If you do it, can you tell us if the downgrade its result (you recovered your warranty)?

Can't i just flash 2.3.5 again after my warranty??

I'm sorry but you keep bringing this up and I have answered it numerous times. I told you here how to do it before.
Here it is again.
BTW: I HAVE NOT TESTED THIS MYSELF.
First of all, you need to get SwiftBootloaderBuilder from here.
(You also need .NET 3.5 SP1 installed, if you have Windows 7, afaik it is pre-installed with Windows)
Also download the correct non-fastboot KDZ for your country/provider & KDZ Updater.
Put your phone in fastboot and use the following commands:
Code:
fastboot -w (this wipes data & cache partitions.)
fastboot erase boot
fastboot erase system
fastboot erase recovery
Then open SwiftBootloaderBuilder and choose 'remove fastboot & recovery' Press OK to any warnings, then your phone may restart. (If it doesn't, then just press 'Reboot device')
Your phone will hang at the LG screen, in this case, pull the battery and USB cable out. Get ready by leaving the battery out, and then hold Volume Down and plug the USB cable in, while still holding volume down to put the phone in Download Mode. Fire up KDZ and choose the .kdz file you downloaded earlier Ensure that the type is 3GQCT and the PhoneMode is set to DIAG. Then start the flash. Make sure not to use the computer during flashing as it could cause KDZ to stop working and render your phone useless (bricked.)
It should reboot into Android 2.1, with fastboot & recovery removed and your warranty intact.
Hope it helps.

I think is possible

u use recovery to downgrade, search in the 4rum

Would it work if I flash by recovery then just unroot to remove fastboot and recovery???

When unrooting, you don't remove fastboot and recovery. To remove fastboot and recovery, use the guide I posted above.

This is where a/b partition does his magic.
If your update failed then phone will boot on the previous partition to make the update again
I think you can still change slot partition on fastboot with the right driver's installed and right command

here is a guide if u dont know how to change partition:
download fastboot from here: https://forum.xda-developers.com/showthread.php?t=2317790
if u already have fastboot it might not work because its not the latest version but it is the latest version from this link
reboot to bootloader by holding power + volume down button while ur phone is shut down (to shut it down just hold power button)
open the cmd-here.exe file from the zip and type: fastboot devices, if it shows u a string then ur good, if no strings u need to download ur phone's driver and if more than one then unplug ur second phone from ur pc
then type: fastboot --set-active=b if that didnt fix it try --set-active=a and if that didnt fix it then u cant fix ur bootloop using partitions

Any kind of help is greatly appreciated

IT IS NOT THAT MUCH HARD
i found a way to do it
>>First download latest magisk apk
Link - https://www.google.com/url?sa=t&sou...FjAAegQIAxAC&usg=AOvVaw2Xrf3Ndu6oqxqBK9TKilSx
>>Then download stock rom here

Sog1qkyLy9lXieK2vR&ampcf=1&cshid=1621397379367
[Sorry but u cant use latest firmware cuz its not available]
>>Then extract it and get boot.img
>>Patch it using latest magisk manager
Now lets go to install it
U can use pc if u have but if u dont then follow these steps
Share firmware file and patched boot file to other device and install bugajear app on other device [link- https://play.google.com/store/apps/details?id=eu.sisik.hackendebug]
>>Then open ur tab go to settings enable developer option and then enable oem unlocking and usb debugging on it
>>Enable usb debugging on other device also
>> Connect both through otg and then allow permission then reboot ur tab to bootloader [power+volume up button] u can use app also for that
NOW LETS UNLOCK BOOTLOADER FIRST [it will eras ur data take a backup]
>>Open bugajear after u boot into bootloader
>>Go on last option with sign of electricity and press on [<>] bottom right of ur other device
>>Type [fastboot flashing unlock] then run it
>>Choose yes on ur device with volume buttons [ sometime u press right volume button but it doesn't work then try other]
>>It will erase ur device but ur bootloader is now unlocked now just reboot to bootloader again
>> Now type [ fastboot flash boot ] click on embed sign on top right corner and then link ur file and run it
>>Now just extract ur firmware on other device too and get these files
System.img
Vendor.img
And flash them this is really needed or u end up in bootloop
And tada ur all set just reboot ur device and ur rooted
I am also tryibg to get twrp but it will take sometime

My main goal is to use the tablet as an LCD display for my PC sensors.
I need root to auto enable tethering on usb plug.
Device is still rebooting from the flash for now, but I think it should have done the trick for my purpose.

@Aks BRAR SOTHA Did you manage to prevent Android from updating ?
It tries to update and update fails. Then try again and again..
Edit: For my purpose, I can just disable WiFi, and no more update. But this is not the elegant way :/

This is my number
Ouiquqywyt
O-9 and u-7 decode this i cant share straight msg me here on instagram. I used letters according to numbers on qwerty keyboard

I just found this thread and thanks for the instructions. I was able to successfully root my tablet using this method. Of course it kept wanting to update and failed during the process so I thought I would try to get the update patched...
with the device rooted (with the old firmware) allow the update to download
get a shell with `adb shell` and then `su -` (approve the root request on the device)
the zip file is located in `data/data/com.lenovo.ota/fileslenovoota` unzip it and copy boot.img to somewhere the magisk app can find (I used `/sdcard/Download/`)
patch the boot.img with magisk
use adb pull to get the patched img onto your computer
boot into fastboot and flash the original boot.img, system.img, vendor.img from the zip provided above (in the original instructions)
reboot the tablet. The update should now be able to complete
once complete, reboot into fastboot again and flash the updated patched boot.img
reboot and you should be on the latest version and be rooted.
I've also attached the patched boot.img from the update
