[Xoom Q&A, Help & Troubleshooting] andlommy:
Hi all!

Typical problem around these forums : "played around wtih different ROMs and now don't have 3G anymore".

I had ICS from team EOS for wifi installed on my MZ601 (european 3g aka everest).

Now when EOS have released a version for MZ601 i've flashed it, but get no 3g.

Now i have flashed

EVRSU_U5.H.6.1-38-9_SIGNED_USAEVRSTURTIRD_P016_A006_M004_HWumts_ever est_Service1FF.sbf.gz

Still no love and some commands output are as follows:

adb logcat -b radio

^^ wonder why stingray....

^^ wonder why kernel command line is modelno=MZ600

^^ wonder why baseband is CDMA

^^ wonder why modem panics

I got an SBF for android 3.0, 3.1 etc for everest, flashed it via RSD, no love, updated builds to 3.2 (to get new bootloader) - no love, triet tiamat 2.2.2 and pretty much all other ROMS with similar result. Tried guides how to unlock 3G when upgrading to 3.2 (the old guides that were written when everybody out there was running 3.0 and wanted custom 3.2 builds)...no love

Can it be that my radio rom got overwritten when i installed some other ROM and now contains incorrect data?

Is there any chance i can get the 601 radio (CM5.sbf i think) somewhere?

Where is the model name and kernel boot parameters stored?

It's not just me with this problem, afaik.

Maybe some gurus will be able to help in this tricky case.

Much appreciated in advance :)
