HTC DESIRE d820s:
Boots, but black screen. Computer picks up phone with directories. Tried with kernel from the Umi 5.0 and 4.4.4, Bootloop.

UMI 5.0:
Installed TWRP 2.8.7.0 (http://www.mediafire.com/downloa ... 0_2015-07-18_5.0.7z)
Tried using a different secro.img. (Apparently Provides IMEI and Baseband) But nothing happened.
Flashed Gapps through TWRP, camera dissapeared, and installing google camera comes up with error: "Cant connect to camera"

Alcatel Flash Plus
Doesnt even boot.


Ideas to try:

• Managing to extract the Modem from 4.4.4 and flash onto 5.0? (http://forum.xda-developers.com/galaxy-s2/help/extracting-modem-bin-rom-t1198827)

• •Install ES Explorer or use your favorite root browser
  •Enable root access (in ES Explorer > Menu > Root Explorer > Mount R/W > Select RW for '/' and '/system)
  •Copy modem.img to your SD
  •Navigate to /system/etc/firmware
  •Rename the original modem.img to modem.bak
  •Navigate to the new modem.img and copy
  •Navigate to /system/etc/firmware and paste
  •Make sure permissions show '-rw- r-- r--' (Directory list) or 'rw- r-- r--' (file properties)
  •Reboot
  (http://www.chinaphonearena.com/forum/Thread-Mod-MTK6589-3G-Fix-multiple-modem-img-pack?highlight=modem)

  
  

• Obviously is a baseband issue. "MOLY.LR9" is for kitkat, whilst the other is "MOLY.WR9.W****"
• Try to rename Modem files? (Modem_1_ltg_n.img -> Modem_1_lwg_n.img) or when porting Kitkat Modem, vice versa?
  

Works!! Baseband sucessfully changed from TCL's moly to unknown. now we just need to find a correct MODEM for the bloody thing.
Tried EVERY single modem i could find, Renaming, everything, Still doesnt work...

Possible kernel??????https://android.googlesource.com/kernel/mediatek/


Turns out the TCL M2M does not support UMTS. This may be part of the issue why the sim does not find a network (Simcard is found though.)
Read screenshot description for modem type. Umi Modem Shows bands enabled under UMTS. in the TCL modem. None are selected and are greyed out.

• Possible fix: Change out the MTKengineering mode APK (*#*#3646633*#*#)
• Another fix. Backup KITKAT nvram. Restore on 5.0
• Another fix: need a mt6752 phone ROM which supports wcdma. (Jiayu s3. TCL m2m 3s)
