Mine is "M4G2DE", 2 other DZ's I had bricked, never checked what the EMMC serial was though, this phone is a warranty replacement, the other phone died in 2 weeks, the one before that lasted a few months, died after a crash from angry birds. This phone seems to be fine tho. I rooted it, installed CM7, done plenty of backups restores and flashing, a few battery pulls too, since my carrier has a 28 day return policy (after that its all covered under warranty) I tried to mess with the phone as much as possible within that 28 days so if anything went wrong I could just walk in, fill out some paper work and work out with a new one. I hope this phone is okay..

I have had quite a lot of issues though, I've had to repeat the PC10IMG treatment like... 8 times? And rooting it again, because for some reason my device reboots right after booting into home screen, rendering it unusable and also making it heat up... Currently I have Virtuous Sense and that has been stable. Some random reboots sometimes, but that has to be expected when overclocking...

I've tried RCMix 4.0, Android Revolution HD 7.0.0, Virtuous Quattro RC3, CM7 stable AND nightly 263. Had that problem with all of them. It did seem to have something to do with the radio, becausewhen trying to toggle 2G/3G, airplane mode or mobile data it would reboot. Kinda depressing...

[G2 and Desire Z General] crestofawave:
If you read some of the post back, this actually varies. There's people with 2.09GB, and others with 2.17GB, et cetera. That being said, I have the M4G2DE chip and it's been working fine ever since I bought it. I've done a LOT of flashing on it, I even recall flashing about 16 times in one day!

So to anyone that has a "defect" M4G2DE chip, don't panic. This really varies among cases, it could be random for all we know. So we're quite likely just as safe as the folks with the SEM04G chip are.

Well... from my experience it seemd like FS corruption issue, do not know what exactly happened. I was using Dolphine HD to look at some Flash video when the phone hanged up, no FC, no Wait please, just get unresponsive. I was running the RunnyDroid 5 atm.

The lockdown happened before, but without me noticing to loose, but this time I've lost for example Trillian account setup, XDA app setup (and it was behaving strange after that) and some more... mostly perhaps things loaded in memory, so perhaps it just corrupted data on hard reboot.

But still it seems strange to me, that this should not happend at all and those lockdowns were not once only.

Hi all! I came here to check my chip serial before I install kbeezies DataSwap mod and unfortunatelly mine says "mmcblk0: mmc0:0001 M4G2DE 2.10 GiB" so I've got the bad batch. Do you think I can still go with the DataSwap mod? I use my phone a lot, with a lot of applications, but usually no games and bells and whistles, just purely for work (email, office documents, reading pdf's, books, calendar, text messaging, ...)

Also, mine DZ is almost 20 months old, so I am close to replacement but I still do not want to fry my chip (what if my operator does not have any phone with qwerty and I will have to stick with my DZ). I flash a lot, really a lot and I did not have any problems so far.

Thank you!
[G2 and Desire Z General] kbeezie:
Since you got the one more prone to dying, I would avoid any kind of 'swapping' on the internal memory. In fact you might even want to go with the SD-EXT route without doing dataswap so that you reduce the strain on the internal memory further (as all the downloaded apps will be saved to the sd-ext partition on the SD card instead of internal).

So yea no data swap, encouraged use of /sd-ext, to reduce the usage on the internal memory if you're paranoid. Doing so will cut down on write actions on the internal memory. (reads aren't so bad, and since /system is usually read-only that's not usually the biggest concern).
[G2 and Desire Z General] jmaciak:
Thank you for your hints. I just finished preparing 2GB SD-Ext and am going to apply your patch. To be hones, this phone went for almost 2 years without any problem and there are just few months remaining. Also, if the internal chip is fried, I will fight for replacement. How would they know it's unlocked and rooted, when the internal chip is dead anyway? Do you think it would be possible to S-ON and put regular recovery again if only recovery will be available?
[G2 and Desire Z General] kbeezie:
The problem is that when the chip dies its not always so obvious Usually you get a lot errors but can still see the boot loader or recovery (but end up with a lot of failures trying to wipe or reflash new stuff)

As a result if the chip goes bad you may not even be able to revert it to SHIP S-ON, at that point some people take the risk of intentionally bricking the phone so it can't even turn on to hide the obvious.

Some people because they can still get into recovery try to squeeze some life out of it by doing something things like booting android off the sd card.

The phone was just sitting on the table all night long, connected to the charger, WLAN on and automatic app updates enabled in Play Store.

This morning it just displayed the black screen with red triangle and exclamation mark in it (recovery I guess?)

Managed to revive the device by factory resetting it - but I'm afraid this issue is going to return - and way earlier than this time (had the phone for ~1,5 years)

Are there any reports of successful warranty claims because of this issue?

I have a Desire Z that all of a sudden died too, after trying to update a couple of apps in the Google Market.

Well, I called HTC and talked to their technical department. First thing they wanted to do was walk me through a couple of troubleshooting steps because "we can most likely get it running for you again, sir", but I told them not to bother with that.

After I explained to him what my own research had taught me (the dreaded eMMC problem), they told me that they were not aware of this problem. HTC did not have anything in their system saying these phones were affected with bad eMMC chips, and they said I was the first person ever they talked to that had this issue.

So, as far as warranty claims go: good luck. I did tell them I thought it was just ridiculous that HTC pretends there is no problem, but they assured me again that I was the first person that they talked to that had this problem, and they couldn't do anything because the warranty expired four months ago.

Running at 1500Mhz. about 2 years and 3 months old. Flashed about 5 roms including a few radio updates. No issues whatsoever, however not a very heavy user.

Girlfriend has the same, however that one gave me a lot of trouble. Up till semi-bricking during a pretty standard rooting operation; just stopped in the middle of flashing a rom, leaving me with nothing but a bootloader wich was S-On and a probably halfinstalled rom wich didnt boot ofcourse.

Tried everything for about 4 long days of studying the forums and internet in general and trying things like goldcards, RUU's etc etc but nothing worked.

In the end I had to send it to a small company that was able to perform a JTAG. The report stated that (as I expected) the JTAG was needed to revive the device (they also tried other methods first).

Now this thing has the problem of random reboots after using Spirit FM for a random time or if GPS is used (Sygic or Google navigation both make it reboot after about 45 minutes of use)

Won't suprise me if this one also has the dreaded eMMC M4G2DE and will check this as soon as she is here again and post.

Might be useful to note: her phone has also been returned for warranty. Suddenly the phone's mic died (able to hear, not able to speak when being called) and together with that there was a problem with the headphone jack (no sound or sometimes sound that died after 5 minutes)

I read the whole thread and saw that a lot of people with the M4G2DE had a phone that had been back for warranty...

Regarding the restarts, I have the experience that many roms out there have kernels undervolted, but this make the hardware more unstable. I myself experienced this with my phone, and debugged this for around 3 months, when found that with the voltage settings in htc's release kernel the device had no instability issues more. Since then, when installing a rom, I always begin with replacing the kernel in it with my one. I theory this may eat more battery, but at least no random restarts or other.

M4G2DE with thermal compound

mmcblk0: mmc0:0001 M4G2DE 2.10 GiB

i had no problem whatsoever and i ran it at even 47 degrees celsius / 117 fahrenheit (Battery Temp) toasting my hands (charging and) running it at 1800 mhz (many times(power hungry)) until i saw that it has the same performance with 1516 mhz. Only below 1516 mhz the performance drops.

Maybe nothing happened because i filled my whole phone with ELECTRICALLY NON-CONDUCTIVE THERMAL COMPOUND used for pc cpu ,so every piece would have thermal cooling from that metal piece.

And the Thermal Paste MUST be a PURE ELECTRICAL INSULATOR.

For example Arctic silver 5 is slightly capacitive, so you can not use it, because you will ruin something.

Arctic Silver 5 was formulated to conduct heat, not electricity.

(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)

But Arctic silver Ceramique 2 is up to the job being a pure insulator.

Céramique 2 does not contain any metal or other electrically conductive materials. It is a pure electrical insulator, neither electrically conductive nor capacitive.

So i was pretty confident about it

If i would not have done that, all the heat may have stayed inside fry something there because we all know that phones do not really have ventilation.
