Root [GSM] Missing Baseband

[R4WK1LL]

Hi guys, currently my phone is stuck on boot loop (after HTC logo, it'll keep restarting without going into boot animation), but I can flashing stuff without any issue (with unlocked bootloader, S-OFF and Super CID). I've tried some things: flashed some RUUs, installed custom recovery (CWM / TWRP / 4EXT), but in the end when rebooting the phone after successfully flashing RUU or trying to get into the recovery --> another boot loop.

When I check the vars, the baseband value is null, even after flashing RUU (then reboot). If I manually flashed Radio/Firmware (ex: 11.25.3504.06_M), or boot.img from my current ROM, then check the baseband right away, it'll show the version number correctly; but after rebooting the device (which goes into boot loop again), then I check the baseband, it'll be empty again, so it seems like it just won't stick, which is probably the culprit.

Some infos:

version: 0.5
version-bootloader: 1.53.0007
version-baseband: N/A (after every reboot)
version-cpld: None
version-microp: None
version-main: 1.20.401.8
serialno: ~snip~
imei: ~snip~
product: shooter_u
platform: HBOOT-8260
modelid: PG8630000
cidnum: 11111111
battery-status: good
battery-voltage: 5719mV
partition-layout: Generic
security: off
build-mode: SHIP
boot-mode: RUU
commitno-bootloader: 10e127f0
hbootpreupdate: 11
gencheckpt: 0

Any ideas on what should I try next?

If your device won't boot after a successful RUU, I would be concerned that there may be a hardware issue. I'm only ASSuming here but I would think that the phone could boot without a baseband, if it's not sticking, but maybe not.

How are you flashing the baseband? As a PG86IMG.zip? Regardless, an ruu would flash a radio as well... Perhaps your partition is corrupt??

Also, how are you flashing the RUU, and which RUU are you using?

Yeah, that's what I'm afraid of.. but I want to try any possible options first before going to that conclusion.

I did it via fastboot flash zip (Radio-Baseband_11.77.3504.00P_11.25.3504.06_M). Btw, the RUU did flash the radio (checked it after flashing), but it's gone after reboot. How do I check whether or not there's any corrupt partition? Is it recoverable?

Also, how are you flashing the RUU, and which RUU are you using?

These are the steps that I followed:

1. fastboot erase cache
2. fastboot oem rebootRUU (wait about 30 secs)
3. fastboot flash zip PG86IMG.zip (I've also tried to do this step twice in a row as suggested in a thread, but no dice)
   
4. fastboot reboot

As for the RUUs that I've flashed:

• 1.20.401.2 I don't know the full version number (got it from Free 3VO_V2), but it works back then.
• RUU_SHOOTER_U_ICS_35_S_HTC_Europe_3.28.401.1_Radio_11.77.3504.00U_11.25.3504.06_M_release_262714_signed.zip
• RUU_SHOOTER_U_ICS_35_S_hTC_Asia_WWE_3.28.707.1_Radio_11.77.3504.00U_11.25.3504.06_M_release_264110_signed.zip

Also, the only recovery that persist and I can get into is philz-touch-6.46.1_shooteru.img; so for now I still play with it.. although I got this messages:

E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't mount /cache/recovery/last_install

Thanks for your reply.


Edit: Finally got it to work!

Through PhilZ recovery, I wiped everyhing in sight (lol) and was able to use custom restore to partially restore my Nandroid backup (since it won't restore .android_secure, I got to extract it manually). Also, before the restore process, I need to disable MD5 check, coz it keeps complaining about missing fsinfo.md5 even though the nandroid.md5 is there. After that, I finally able to flashed & go into 4Ext to do a full restore properly.
