[myTouch 4G General] xdviper:
A lot of bricks been happening, and #G2root has come down to the eMMC chip being the culprit, it's not a defective one but one that goes bad after a while. It just dies for unknown reasons. I'd like people to post their eMMC serials, if recovery gives them an error such as "can't mount cache, data, etc"

You need adb setup for this, use one of the stickys to get started with adb

1, start up adb and type these in.

adb reboot recovery

2, after the device starts up in recovery, enter this

adb shell

3, and then this, your serial number should come up after mmc0:0001

cat /proc/kmsg | grep 'mmc0:0001'

It looks like M4G2DE 2.10 GiB is the bad one, judging from what the #G2root devs say, but lets see what our side is.

Thanks

And unfortunaly I got the bad one too, rooted with gfree, this is what I got

<6>[ 8.328460] mmcblk0: mmc0:0001 M4G2DE 2.10 GiB

5/20/11 Edit: Added a poll, if you'd like to see more options please let me know.
[myTouch 4G General] Shivansh:
<6>[ 8.596679] mmcblk0: mmc0:0001 SEM04G 2.17 GiB

That's what mine shows. Don't know if it's the good one?

I'm just curious that if emmc is the culprit then how come no one who rooted using the "non" gfree method never had this issue - at least no one in the forums so far has said that they used the non-gfree method and encountered this issue.

This is my second phone that I've rooted with gfree. The first one died when I was trying to restore IcedGlacier nandroid backup coming from RoyalGinger; with the same clockwork can't mount cache errors. I had the eng bootloader and had tried every thing (even sdparted) but couldn't get it to work.

All I'm trying to say is that it may be the combination of emmc and gfree? What do you think?

Since my current phone is also rooted using gfree; I'm contemplating to revert it back to stock and use the other rooting method.

Thanks for trying to find the cause of this issue.
[myTouch 4G General] xdviper:
It looks like you have the good emmc, but still can't be sure.

That's exactly what I wanna figure out, how many people used the other method to root and if they had any errors yet and which method they used. We all need to be a little bit more cooperative and help us figure this out.
[myTouch 4G General] neidlinger:
Here is mine... hope it helps in your quest.
[myTouch 4G General] vqt:
I rooted with g-free method. Mines shows up the same as the OP

M4G2DE 2.10 GiB. Does this mean I have the bad one? Getting a little concerned at this point. I have flashed a few roms, a few kernels and all of the radios in the past 2 months since I got the phone. I haven't had any problem. Waiting to see what others will do as in unrooting and re-rooting with another method.

Edit: I took the plunge and unrooted my phone to stock. Then rooted again with the visionary method. Worked fine. No problems.
[myTouch 4G General] TehVeggie:
Haven't had any problems, rooted via gfree.

It seems like I have the "better" emmc chip though, I've flashed maybe 10-20 times, different roms and kernels. No radios yet though.

Reading about this stuff has got me a bit paranoid, lol.
[myTouch 4G General] jdkoren:
cat proc/kmsg | grep 'mmc0:0001'

I don't get any result when I run this command. I've tried in adb shell and in terminal emulator - no dice. If it matters, I'm rooted with gfree, running CM7 with faux123's kernel.
[myTouch 4G General] lowandbehold:

[myTouch 4G General] h22aboi:
Feels like I won the lottery or something.... I got the "good one".

mmcblk0: mmc0:0001 SEM04G 2.17 GiB

Used root.sh method first, then used GFREE method after that method came out for CID 111111~. I knew my third exchange would be the charm! Or was it four? Lost count.. lol.

I've been scared and kept my phone s-off debloated stock, but now I feel like exploring.

Now to flash TRUEBLUE's panache ROM....
[myTouch 4G General] Phateless:

I am trying to figure this out. I did not use the gfree root method, I actually used the unlockr method.

the cd/adb isnt listing my device and I know I am doing the steps correctly. Going to post this in the Q&A section as well. Thanks for any feedback you guys can provide.

EDIT: Drivers installed through PDAnet. Going to see if the drivers on HTC.com change anything.

Ive also check my phone with the cat /proc/kmsg | grep mmc0 command found here http://xdaforums.com/showthread.php?t=1079025&page=5. didnt get the error.

Side note

As a side note to this topic, attempting to run adb shell was giving me a device offline error.

ran adb kill-server > adb start-server and nothing, was at it for roughly 2 hours this afternoon. Did some digging around and found that sometimes the USB cable could be the culprit. So after 2 hours of killing and starting server, and reading android forums I decided to dig around for my other micro usb cable. Lo-an'-behold device comes online.

Just did a recovery of virtuous fusion and had no issues with the recovery. going to run the commands from the OP and find post my results.

EDIT: Results were SEM04G 2.17 GiB

So from public opinion I have the "good" emmc. Again I just ran a recovery of my phone as well. But whos to say even with the "bad" chip it wouldnt have worked. Many people posting today have the "bad" chip and have been flashing/recoverying for many months.
[myTouch 4G General] thederekjay:
haha looks like we need to start a support group.. i have the infamous "BAD ONE" M4G2DE 2.10 GiB :( same thing with my GF MT4G and she already got the plague on hers, but i recovered with PD15IMG.zip about a month back... knock on wood my phone is still going like a champ and i am the one constantly flashing, only flashed her phone 3 times... go figure :confused:
[myTouch 4G General] TeeJay3800:
It looks like I have the "good" one:

This is BS though. Someone could pay $450 for a phone with a known defective chip, and the manufacturer has no replacement plan in place? There's something wrong with this picture...
[myTouch 4G General] Phateless:
So you rooted only with root.sh, not gfree, and got a failed chip? You are the first one.
[myTouch 4G General] Phateless:
So a temp root + running the command from terminal won't get you the answer?

Buy and sell until you find a good one...
[myTouch 4G General] aznprodgy:
or the first one to vote at least:) I rooted with both root.sh and gfree first try using both methods, then got the fail-pu error months later
[myTouch 4G General] irrompible:
You can run both the commands for the screen and chip from terminal without being rooted. I just tested a warranty replacement the other day by doing so.
[myTouch 4G General] saranhai:
whoaa O____o someone just voted saying that their SEM04G chip had failed....
[myTouch 4G General] TeeJay3800:
I'd sure like to hear what they did and what the situation was. Hope they see this!
[myTouch 4G General] Phateless:
So your good chip failed? You just proved my point.

Gfree causes the fail, and the good chip does not require gfree. The bad chip will ONLY root via gfree which is why it fails.

Look at the poll again. Those who use ONLY root.sh are all good chips and none have failed.
[myTouch 4G General] saranhai:
so if i can root with root.sh then that means im safe rite?
[myTouch 4G General] acsi007:
Hold on a second. Clarknick said his old phone had the good chip and failed-pu. That means he got a failed partition update. Why is this atomatically a failed emmc,? Why can't it be a failed pu caused by bad flashing or some other anomaly? Did he do the adb commands to query the emmc and see if its returning evidence of malfunction?
[myTouch 4G General] saranhai:
yea.. he got fail PU that cud be he flashed something wrong...

but i meant like in the poll..

if u see someone voted SEM04G (failed eMMC)

which is interesting.. lol
[myTouch 4G General] kanman:
I got a fail pu on a bad chip. I am stuck in recovery and cannot flash anything. Can I still send it in for a replacement?
[myTouch 4G General] aznprodgy:
yes my previous phone had the good chip, but I got a fail-pu...I wanted to revert back to stock one day and start off fresh, so I decided to flash the stock PD15IMG in hboot. everything went well until I got an error(fail-pu) right after the update prompt, and it went back to the main menu in hboot. I tried to flash the file again and then started getting the "file is an older version" error. somehow being on the updated radio and trying to flash back to stock caused an error and a radio lockout, leading to a whole **** ton of other problems with my phone. it triggered s=on and reverted back to stock bootloader, however I had complete root access and the current kernel I was running would stick to every rom I flashed. I was basically stuck on 1 rom with a jacked up radio and crappy signal. if you revert back to stock rom or do a factory reset, make sure youre on the stock radio before anything else
[myTouch 4G General] xdviper:
@clarknick27, you had the good eMMC and still had a fail PU?

Did you get any errors in recovery?

Do you still have the phone? I find it odd that a good chip failed, it could happen but then again, it's only odd at this point.
[myTouch 4G General] aznprodgy:
yes, I started to get errors with cache and such. I sent my phone in and got a replacement already, bricked it with some electricity;)
[myTouch 4G General] Phateless:
Yes, at least according to the poll so far...
[myTouch 4G General] Phateless:
This would indicate that the failure is caused by gfree, not the chip. The "good" chip can be rooted without gfree.
[myTouch 4G General] acsi007:
Or.... something else. I share your interest in nailing the cause, but if we run too far in one direction, we might close our minds to some other aspects-- of wiping, flashing, doing things via RomManager vs. CWM, and so on-- that could very well be the cause of partition corruption. Nothing comes out and says "the emmc chip just failed!" unless you can see the cycle errors and whatnot-- so we don't know really what causes the failures. We all apply these steps in different orders, on different builds of the same phone phone, wipe different things, flip from ext3 to 4, flash different versions of pd15img-- so-- there's so many variables here to just blame gfree out of hand.

My wife's phone is still stock and I'm still sitting on my hands... :-(
[myTouch 4G General] lowandbehold:
Well phateless, if you would read ALL of his posts, he did not get the errors in CWM. He received the "fail pu" when trying to revert back to stock using the wrong file. So it was bricked because of user error in flashing the radio. The numbers don't lie. More than 25% of people with the bad chip have had it fail opposed to just 1 device "user error" with the good chip. Those are numbers that would hold up in court right there.
[myTouch 4G General] acsi007:
I'd have to amend my comments, if the court allows, with Jack

http://xdaforums.com/showpost.php?p=14595467&postcount=36

He seems pretty sure about causality.
[myTouch 4G General] Phateless:
I agree, I'm just theorizing.
[myTouch 4G General] Phateless:
You misunderstood. The bad chip phones require gfree while the good don't. So bad chip phones MIGHT be failing because people are forced to use gfree, not because of the chip itself. You see the difference? Classic correlation vs causality.
[myTouch 4G General] dementor123:
Please elaborate on this bricking method :)
[myTouch 4G General] Mathato:
Just an FYI. I couldn't root my phone with the root.sh method and I have a good chip... So I wouldn't say 100% of the time if you can't root with root.sh that you have a bad chip.

Is there a way to get the phone back in working order?
[myTouch 4G General] TeeJay3800:
Do a search in the dev section for PD15IMG.zip. You can flash that in the bootloader, and it will essentially unroot the phone and return it to stock. Assuming it then boots, you can try rooting again or try a warranty exchange. This doesn't work 100% of the time though.

This is disturbing since I believe it's the first case we've come across of a good eMMC chip failing.
[myTouch 4G General] Paul22000:
Failing a root (which I think that is what this thread is about? very confused) or failing period?

I ask because I rooted months ago and haven't flashed anything since then, but it's just now failing all of a sudden. I'm still unclear as to the purpose of this thread aside from gaining information.
[myTouch 4G General] TeeJay3800:
Failing meaning cache errors in recovery or the "fail-pu" message. When you get those recovery errors, it's essentially bricked unless you can "bring it back from the dead" via the method I posted. Some have been successful using that method, but many have not.
[myTouch 4G General] saranhai:
no..

the SEM04G chip was made by Sandisk.

go to ur bootloader if u have eng hboot and check the system info
[myTouch 4G General] saranhai:
what kind of fails do u get?

n also... howd u get them?

did ur rom do bootloops or such?
[myTouch 4G General] Paul22000:
The method you posted -- do you mean the one in post #215? Or something else?

If that's the one, is there a more comprehensive guide on how to "flash that in the bootloader"?
[myTouch 4G General] Paul22000:
Phone was Force Closing on literally everything and freezing extremely often, which made it literally unusable.

I went into recovery, did a backup, and then wiped the phone.

After that, the phone would no longer boot ANY rom whatsoever past the MyTouch 4G screen, and that is *including* restoring the backup that I created 3 minutes before I wiped.

Flash ANY rom -> click reboot -> won't get past MyTouch 4G screen.
[myTouch 4G General] saranhai:
if ur talking about flashing the PD15IMG file..

1) download it

2) put it on the ROOT of ur sdcard (not in any folders)

3) boot into hboot (it will find the file)

4) wait (ull see a little status bar at the top right corner) DO NOT POWER OFF THE DEVICE WHILE ITS RUNNING
[myTouch 4G General] TeeJay3800:
Are you getting cache errors in recovery? If not, it might not be as bad as I thought. If you are, your only option is to try the method I suggested in post #215 (and in the post above this one). I wish I could link you to that thread, but it's bookmarked on my home computer.
[myTouch 4G General] saranhai:
what rom were u using before?
[myTouch 4G General] Paul22000:
Yes, getting cache recovery errors as well.

[myTouch 4G General] Paul22000:
Damn. I flashed the file as outlined above.

It said "Press power to reboot" so I did.

It went to the MyTouch 4G screen, sat there for a while and then rebooted. Then it went back into CWM.

I didn't get any FAIL-PU messages or anything...

But no progress...? What does this mean? It's not "bad" but it still won't work?

Where can I go from here? (Since I haven't gotten the Fail-PU errors)
[myTouch 4G General] TeeJay3800:
No, that's not the right thread. That is the radio thread which is completely different and will do you no good in this case. I can't seem to find the file you need to flash to [hopefully] restore your phone to working condition. It's here somewhere. Someone else should see this and link you to it soon.
[myTouch 4G General] Paul22000:
So there is another PD15IMG file that is not the radio?? :confused:

Someone please post I'm sitting here dying :(
[myTouch 4G General] TeeJay3800:
Yes, the restore file has to be flashed in the bootloader, and the bootloader only recognizes files named PD15IMG.zip. Unfortunately, Friday evenings are not high traffic times on forums. I'm about to leave myself in a few minutes.
[myTouch 4G General] Paul22000:
Grr, why the heck would people name multiple files with the same name? :confused:

I think I found it. Is this it? [ROM]Glacier_TMOUS_1.17.531.2_Radio_12.28b.60.140e_26.0 3.02.26_M_release

Unfortunately, it's 312 MB and will take 53 minutes from this filefactory garbage. So much for going to T-Mobile tonight :(

Is this the right file?

Thanks for the help. At this point, I'm willing to just find a way to really brick my phone (without physical damage) so it won't turn on anymore.
[myTouch 4G General] aznprodgy:
yes thats the right one, just rename to PD15IMG and boot into bootloader
[myTouch 4G General] Paul22000:
Yay! It flashed successfully! Thanks all!

Unfortunately, now it just loops forever on booting at the MyTouch logo screen:

It's been looping for 20 minutes.

What to do now? How do I know for sure if it's *truly* bricked and unrecoverable?
[myTouch 4G General] TeeJay3800:
If it still doesn't boot, I'd say the phone is bricked. The good news is it is no longer rooted and now has the stock bootloader and radio, so you should have no trouble exchanging it.
[myTouch 4G General] Paul22000:
Holy ****

I pulled the battery after looping for 20 minutes or so and had pretty much given up hope.

I put it back, turned it on, and HOLY **** IT BOOTED

:eek::cool::D:cool::cool::eek::eek::eek::):):):D:D:cool::eek::eek::eek::D:D:D:cool::cool::cool::D:D

WOOHOO!!!! THANKS ALL!!!

I have to wonder though if the "recovery/cache" errors were really hardware related??? Because now they're gone (I hope???) :eek::eek:

Anyway, thanks again!!!! :D:D
[myTouch 4G General] silentsnow31802:
Thats amazing. Im glad you were able to get it recovered. When I read you had the good chip my hopes for you went up. Im going to try this on mine, i have the bad chip though so im not holding my breath.

Didnt work for mine, Fail-PU... Oh well.
[myTouch 4G General] Paul22000:
Crap, I think I spoke too soon.

I put in my google credentials and it started downloading a Google Maps/Gmail updates and started force closing and freezing again (probably cache related??? :confused::confused:)

God !#!@#!#!@ it

So is the device truly f*ck*d?
[myTouch 4G General] dementor123:
Fail-pu, really? Bad chip is so consistent!
[myTouch 4G General] acsi007:
Why don't you try booting into hboot, and then wiping all the data and caches that are specified in a lot of the new rom installation threads-- dalvik, etc etc, including the advanced menus. You want to wipe all the optional/user created data and cache stuff you can. See if that puts you on a clean footing.

Worst comes to worst, flash the pd15img again? Just a guess - many rom flashers seemed to have success a second time around.

Good luck- interested in your situation - you're "everyman" as that book said (which book was that?) - representing many of us...

Edit: wait - after flashing stock, do you even gave a CWM recovery to get into? and do you have any options to "fix permissions?" that seems to help a lot of force closes on aftermarket roms, dunno if, again, that's available to you anymore...
[myTouch 4G General] Paul22000:
Nope, no CWM anymore. Flashing the stock rom/hboot wiped CWM out.

I *think* I have a 100% out-of-the-box MyTouch4G except

A) 0.85 hboot rather than the stock 0.86 hboot. [Edit]: Woops, I misspoke. It DID go back to 0.86 stock!

B) And of course what I'm guessing seems to be the "cache" errors, which I'm guessing is permanent and unfixable? Do you know of anyone that had cache errors and then fixed their phone including the cache errors?

Is there a way to check if the cache is still messed up (permanently) via some adb command?
