[important note] ICS LEAK FIRMWARE ZIP and DOWNGRADING

This is kind of related to development, and still really important since those flashing Leak ROMs might not read the General section and not know if I posted this there. That is why I posted this here.

If you flashed any PG86IMG firmware zip for the Virgin Mobile leaks, you might not be able to go back.

EDIT: CHADS DOWNGRADE THREAD: http://forum.xda-developers.com/showthread.php?t=1641461

NOTE: This is not specific to freeza's zip. Any firmware zip for the leaks is the same.


Why?

The leak firmware has a file, dzdata_4g.hdr, which no other official firmware has.
The only similar thing other leaks have is dzdata.img which has confirmed not working since people flashing 2.17 ruu (which has this) are still showing the Virgin Mobile banner and having problems.
Downgrading will leave you with the Virgin Mobile dzdata_4g.hdr.

TL;DR/easier to digest
Leak has dzdata_4g.hdr
No official firmware RUU does
Downgrading leaves you stuck with dzdata_4g

What is bad about keeping the Firmware

If you have flashed the zip or have tried downgrading from it, you might be one of the few that have problems with:
-No 3G, just 1X
-No VPN
-More bugs
And everyone will be stuck with the "Virgin Mobile" banner.
Also you're flashing radios and firmware from an unnoficial firmware for a different device. This can cause a lot of issues.

If you aren't having problems and you flashed it, good for you.. Some do but most don't..

EDIT: We're marked as Virgin Mobile so we'll be at the bottom of the tower priority.. among other things..

Can I still flash the firmware zip minus dzdata_4g.hdr?

Try it and report back. It might brick or phone or cause random reboots with the ROM.

Is there a fix if I already flashed it?

See here: http://forum.xda-developers.com/showthread.php?t=1641461

Summary:

The point of this warning is that if you flash the leaked firmware, there is a chance of you having problems. This chance is pretty high since I'd say like 1/10 of people have no 3G and signal quality for a lot of people got poorer.
If you get these problems, there's no going back. There's no way of fixing them.

Whether it's worth taking the risk or not is up to you.


Edit: This kind of explains the situation were in right now:

BTW....if anyone can confirm that they can roam on data after flashing the VM firmware please let us know! I believe data roaming may not work any longer.


And to explain why I don't believe the Sprint ICS leak....very simply....all the rcdata.imgs from our ruus contain the same exact thing....the partition (RCData) is the Radio-Cust.(om?)er?) Data partition and holds pri information and roaming data!

So quite simply....we flashed a file that was built for a different carrier and are now marked as that carrier in different areas of the network.....this WILL conflict with other things as more of us use our devices at different levels!


ADDED AFTER..... Chad has just confirmed with Qualcomm that we have messed up our devices PRI! There is no way to revert from the VIRGIN MOBILE PRI!

The ICS leak may be our fix as it could contain a updated PRI that would be accepted by our devices partition!

I happen to be one of those lucky chaps who flashed it and are suffering from extremely poor signal...:(
I flashed it and went a few places and had what I think is extremely poor signal, but every time I checked my wifes phone's signal (stock Epic 4G) it is the same. Maybe just coincidence?

I upgraded to the firmware and then decided to go back to the 2.17 firmware and I don't have any problems?

im not entirely sure how true this is cause I just nandroid back to WarmTwoPointThree and using my 4g hotspot from my Evo 3d
4G still works with the firmware, I never said anything was wrong with 4G. So does hotspot.

Go to settings, about phone, network and tell me what it says for your network operator.

Also you did flash the firmware right? or did you flash the roms without firmware?

Only some are actually having problems, but the point is, if you flash Freeza's firmware there is a chance of you having problems. If you have problems, theres no way of fixing them.

Also the chance is pretty high as many users have been reporting of no 3G, VPN, etc.

With the virgin mobile banner am I no longer in the Sprint database or is it just cosmetic/visual that can be edited with eri.xml ???

I appreciate the warning, but maybe it was premature? I flashed the fw with no issues, and I've been on 2 ics builds and one 2.17 without problem.

I Flashed the firmware right into bootloader and I dont see where you are seeing your network operator

I flashed Freeza's ics firmware but my banner never changed to virgin mobile even though it seemed to work since voicemail didn't work. I was able to run 1.13 RUU and it seemed like everything was back to normal.
I also haven't had an issues with any rom.

I flashed while on Newts one S. And was able to restore to Nocturnal Adrenaline just fine.
