[Q] Trying to put stock recovery back for OTA 5.11.1540.9
Hope that anyone can help me with the following:
I normally have Openrecovery-twrp-18.104.22.168-m7 running on my M7.
However, with the new software update of 5.11.1540.9 pushed out, I normally go back to original recover, then update my software by downloading it an installing on the phone.
A couple of months ago I changed my version, originally an ATT phone, to I think a European or WWE version. I am not sure anymore.
Anyway, when I try to flash the original recovery ecovery_Cingular_US_3.17.502.3.img back and reboot in to recovery I get a black screen and eventually a phone icon with exclamation mark.
After holding the power button for a while, I can reboot and get back in the phone or restore TWRP.
My question is, does anyone know how to get the original recovery working again so that I can run the update.
This is the info of the bootloader:
(bootloader) version: 0.5
(bootloader) version-bootloader: 1.57.0000
(bootloader) version-baseband: 4T.27.3218.14

(bootloader) commitno-bootloader: dirty-e47fb74b
(bootloader) hbootpreupdate: 11
(bootloader) gencheckpt: 0
I rather do not wipe the whole device if I don't have to. Before I changed the firmware to European or WWE I was able to restore the original bootloader at leisure. So I think it would be best to go back to the correct country firmware, or find a recovery file that does work with my current firmware.
If I can install the latest Developer Edition ROM with TWRP, and have to wipe, that is fine. I don't want to risk bricking my phone with doing all kind of updates. Have done so many and it is still working, would hope to keep it that way
Any help appreciated.
