HTC U11 Battery issue

[littledaga]

Hello,
Hope someone can help me, I've read through alot of posts before asking, I have a strange issue. When my EU HTC U11 Unlocked S-ON is turned off and plugged in the battery charge icon always show as empty with the red light, fastboot see's it as empty, so I can't flash anything that way, I get RU_BATTERY_LOW error.

If possible could someone provide me with links so I can try another DSP, RADIO, Bluetooth TWRP backup.

DSP is showing as UNKNOWN on the Fastboot download screen.

Oreo_WWE_Single_and_Dual_SIM_Radio_BT_and_DSP
Oreo_Radio_BT_DSP_TWRP_Flashable_v2_Euro

I tired these via TWRP with no luck.

Any help would be appreciated.

Try to flash the same DSP from my post - https://forum.xda-developers.com/showpost.php?p=80620553&postcount=1267

Thanks for the response, I'm stuck at the moment because I flashed a stock image from TWRP, which wiped out TWRP and root. So now I can't fastboot images at all due to the incorrect battery level.

Any ideas are welcome.

Glad this is a old phone

Try to flash RUU for your cid (2.33.401.10 for SINGLE SIM)
You will lose all data on internal card and all user applications along with the settings, so make backup before!
Go to https://forum.xda-developers.com/u11/how-to/collection-htcu-u11-ruu-firmware-t3612048
This is your RUU - https://androidfilehost.com/?fid=746010030569951433

When I try to flash RUU from sdcard I get RU_BATTERY_LOW please connect charger (0% < 30%) even though the battery shows 70% charge in the OS.

Try to flash hosd_signed.img from this firmware (2.33.401.10 for SINGLE SIM) before ruu flash.
- In bootloader mode run in command line:

fastboot flash hosd hosd_signed.img

Then reboot in Download mode and flash ruu again.

Thanks alot, flashing the hosd fixed the incorrect battery level.
And RUU and TWRP flash now without issues.
