Hi,
A few days ago I tried to update my SM-P900 tablet after 3 or more years without updating. I tried to flash this ROM (https://forum.xda-developers.com/ga...7-1-xsm-p900-unofficial-cyanogenmod-t3524788/), but it didn't boot. I flashed the recommended bootloader and recovery with Odin, but I'was not able to boot. Somehow, neither booted Lineage 13 (https://forum.xda-developers.com/ga...t/rom-cyanogenmod-13-0-android-6-0-1-t3366834) nor Resurrection (https://forum.xda-developers.com/ga...lopment/rom-resurrection-remix-5-8-2-t3563635). The only ROM I managed to get working is CM 12 (https://forum.xda-developers.com/ga...t/rom-cyanogenmod-12-lollipop-5-0-1-t2971945/). I thought that the problem was the bootloader, and someone suggested that I flash a more recent (at least lollypop) bootloader. According to Phone INFO, my bootloader version was P900XXUANI1. I tried again and again to flash the BL_P900XXU0BPA1.tar.md5 file, but, despite Odin showing the PASS! message, Phone INFO kept showing the same bootloader version. After that someone recommended that I flash the most recent stock image, so that I get a recent bootloader, that is what I tried to do.
I downloaded the file Samsung_SM-P900_(P900XXS0BPL2_P900OXE0BOI1_Russia_v5.0.2)_by_ (FirmwareOS.com) from a sammobile kind of site. What I look for is that ...BPL2 version that seems to work for other people. But after flashing it, the tablet doesn't boot and I can't access download mode. The only thing that i get to boot is the stock recovery, but it doesn't have the flash img option nor the reboot in Download mode that TWRP had. The only options I got are "Update from external storage" and "Update from ADB". Either of them don't let me flash a full factory image nor, apparently, another bootloader or custom recovery. When I try to flash it I get "E: footer is wrong \n E: signature verification failed" and if I do it via ADB, the error shows right away after a 0% transfer.
EDIT: Other symptoms I found are:
- I can't manage to power off the tablet using just the buttons: it always reboots unless I select the Power off option in the recovery. Also if the tablet is connected by USB to the charger or the computer it always try to boot.
- When the tablet is connected via USB and I try to power it off, the tablet reboots and shows a battery symbol, but is gray and kinda strange.
I'm pretty desperate now. This is my wife's tablet and I tried to update it so that it was more secure. I'm screwed.
Any ideas? Is this fixable?
Thanks in advance.
Regards.
