If you accidentally brick your device by ticking erase after download or lost your SN when flashing unnecessary stuffs in QFIL you come to the right place ,

1. Firstly the device should still be able to enter EDL mode by pressing VOl + and after still pressing that key connect it to your pc. Another way if you in fastboot is reboot to edl by adb reboot edl and connect to pc.
2. go to tools --> partition manager
3. go to fppartition/fpinfo and read data/partition
4. go to %AppData%\Qualcomm\<port number of your QDLoader port>\something-like-current-date.bin

5. edit with hex reader or HxD LIKE THIS ^
6. insert serial number under decoded text, read from purchased box or back of your tab
7. save file and remember the file location
8. go to qfil and load image by using the saved/modified serial number
9. reboot to fastboot to see the result or go to tab setting status
if still wouldn't boot carry on
10. now from the stockrom folders containing all the files , they will be 2 files 1 which is content.xml and another is content_fullupgrabe.xml the plan is to change content_fullupgrabe.xml to content.xml.
11. With that save content.xml in a save place and thereafter for the content_fullupgrabe.xml file, change its name too content.xml.
12 Try flashing again with the Qfil rom with the related files it should be booting up fine now.

Hi,

very interesting. Here is mine (sda6 / fpinfo) from a TB-J706F, it looks a bit different. (RED xx = Serial Number)

Best regards

I use NV-items_reader_writer for it, item 2497 - read, change it with Notepad and write back.
