Hi everybody,

I hope someone can help me and say how to continue.

I have recently flashed my DZ and installed CyanogenMod.
Now I have the eMMC problem, because I removed the battery, when my phone freeze
during an application update from the market, not knowing the problem with the chip.

I have readed many post about it and now I donīt know how to continue.

Now my DZ freeze at start showing the HTC logo and the clockwork recovery
shows the good known error.

Code:
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
I found many instructions what is to do, but nothing help.

So first I check, if I have the faulty chip.
Code:
# cat /sys/devices/platform/msm_sdcc.2/mmc_host/mmc0/mmc0:0001/name
M4G2DE
Then I found this posts which for me seams to be the most promising.

So I check, if the chip is corrupted.
Code:

Because there are existing the following 4 lines, the chip is corrupted.

Code:
mmc0: failed to get card ready
mmc0: reinit card
mmc0: Starting deferred resume
mmc0: Deferred resume failed
Is this right, because I have found a post, where the user has this for lines and after installing
a ruu everything was allright.
http://wp.daveheavyindustries.com/20...oblems-m4g2de/

I try the factory reset. It freeze.
I try to restore a ruu, but if it try to reboot my phone, it freeze at the HTC view.

So I try to unroot my phone, to not loose the guarantee.
http://forum.xda-developers.com/wiki...tle=HTC_Vision

This havenīt work. Iīm not sure, if I have made something wrong.

Now my DZ is still
VISION PVT SHIP S-OFF
HBOOT0.85.0005 ...
and the support can see that it was rooted.

It is possible to unroot the phone when the chip is corrupted?
Any ideas what I can do, because I would like to avoid to pay for the repair,
because I corrupted chip is not my fault?
I found a post that in the USA somebody paid about 76 Dollar for a new chip.

Greetings,
Rafael
