Install Custom CM7-EX Gingerbread ROM on HTC Evo 4G
The HTC Evo 4G with its excellent hardware capabilities is amongst today’s top most smartphones specially if you look at the 1GHz Scorpion processor, its 512MB RAM and the utterly mind blowing 1GB ROM! When it comes to the software, HTC Evo 4G was released in the summer of 2010 when Android’s latest stable distribution was Éclair. However, Android has come a long way since then. If you’re looking to install a latest Gingerbread ROM on your HTC Evo 4G, carry on reading.

I resolved the 4G issue by downloading the updated rom from here http://download.cyanogenmod.com/get/update-cm-7.0.3.1-Supersonic-signed.zip. I followed the same instructions on this page except I replaced the file CM7-EX.v10.zip with update-cm-7.0.3.1-Supersonic-signed.zip and skipped the optional battery mod. 4G works perfect

The link to the battery mod rom is down.
Nice ROM. Some apps may not be compatible, I only came across one that did not work which was a game I can live without. The app “Land Line Phone Dialer” works with this ROM which is a nice plus. As far as the ROM default system apps, 4G does not appear to be working, No settings to turn 4g on and off that I could find. Has a nice VoIP feature built into the phone dialer. VoIP is glitchy, Have not made a successful VoIP phone call (3rd party app resolved this issue). Wi-Fi hot spot functions very well as an “Access Point” and not an Ad-Hoc. This works very well with my Eye-Fi SD card. I no longer have to pay sprint for this feature. Really nice ROM, I’m glad I installed it. I’m hoping there is an update to resolve the 4G problem but this ROM is well worth the sacrifice since 4G is not available in my area yet.
Is there a reason google navigation doesn’t work? does anyone have a fix for this?
when i try to flash the format all zip i get this message:
amend scripting (update-script is no longer supported
it was necesary to remove it clock work 3.0
install aborted
what do i do to fix that
thnks
i heard there was a issue with the 4g on this rom is that true?…..ill put this rom on when all bugs are worked out
I wanted to know if anyone has had a buggy network connection. My Internet comes and goes but I can still receive and send calls. Also, I think that it also does this when using 4G too. Just asking. I love the rom but just want to make sure Im not the only one experiencing this. Thanks.
Love it!
Thanks!
Worked like a charm =)
Loving the gingerbread theme!
