Not only that, its happened to phones on other roms to. I remember seeing someone saying it happened to them on CM7 RC4
[myTouch 4G Q&A, Help & Troubleshooting] Nicgraner:
Not only what? The method?
[myTouch 4G Q&A, Help & Troubleshooting] theghazi:
I use gfree method,

i have had this phone for 3 months, and changed atleast 3 times a week, from cm7, ice glacier, and so on.
[myTouch 4G Q&A, Help & Troubleshooting] lanternslight456:
I'm exhausted after way too much not sleeping and way to much work...

Basically I'm saying that this can't be entirely RG 1.5s fault because it's happened to people on other ROMs also. It could, I suppose, be an AOSP thing which means CM7, RG1.5, and any other ROM Cyanogen based or AOSP based...

I'm not a programer so I'm not sure, does that make sense?
[myTouch 4G Q&A, Help & Troubleshooting] Nicgraner:
Alright man thanks for explaining it could be an AOSP bug that won't be fixed till official update is launched and other devs get their hands on the kernel and source code to fix well..the source code and kernel lol
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
I used gfree
[myTouch 4G Q&A, Help & Troubleshooting] lanternslight456:
Can anyone confirm this happening to anyone who rooted using any method other than gfree?
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
I spoke too soon... turns out this phone has a broken speaker for the earpiece, can only hear calls if I put the phone on "speakerphone" mode. crap!
[myTouch 4G Q&A, Help & Troubleshooting] lanternslight456:
That's not refurbished, that's defective, I'd get that traded back in.
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
oh yes I am!! I'm calling T-mo tomorrow to ask for another replacement. You know what they say, if it looks too good to be true it probably is.... I couldn't figure out why a phone that looked 100% brand new would have been "refurbished", well, now I got my answer!!
[myTouch 4G Q&A, Help & Troubleshooting] Isubbie:
Well my white one is brand new. Or looks it, nothing wrong here. Maybe you got a bad one? It happens, could of been damaged in the shipping, some rain and water got into the phone. Who knows.
[myTouch 4G Q&A, Help & Troubleshooting] Isubbie:
So I decided to root again, because even if it gets bricked again, as long as I don't change the boot image they really can't tell because the damn thing never booted. Though it does sound like the gfree method maybe the cause of the problem, because that's the method I used.
[myTouch 4G Q&A, Help & Troubleshooting] Nicgraner:

XDA really needs to scan my brain before I post, if it finds that I've got less than 3 hrs of sleep more than 2 days in a row it should block me lol.

Thanks, I was totally brain-dead last night.
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
spoke with t-mo a few minutes ago, got another mt4g being sent out to me. After the second exchange I can request a different phone, too bad they probably wouldn't give me a G2x, it's weird because the G2x would be an upgrade while any other phone they carry would be a downgrade. Hopefully the replacement phone is a fully functioning one and has a good screen.
[myTouch 4G Q&A, Help & Troubleshooting] lanternslight456:
Just wanted to let everyone know, I re-flashed RG 1.5 earlier today using the newest recovery no problems having it ONLY do it's on wipes. Later on, I wiped cache and dalvik. Through both of those events I had no problems (I was re-flashing for some different reasons, not due to problems) Well, I flashed RG 1.6 release, because the auto wipe was removed I did a fastboot wipe and when I got into recovery from there I had the E:\ can't whatever cache...

I went ahead and wiped data\factory reset, wipe cache, wipe dalvik, format system, install RG 1.6, (and I installed the faux BFS update also) and have had zero problems.

I am on the engineering bootloader and gfreed my phone, just thought I'd share that.

Maybe this is fastboot wipe related... but like I said, NO issues installing anything, everything was smooth as silk, it just gave me that readout at first.
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
I think I'm one of those really unlucky mt4g owners, got my second replacement today(to replace the one with a broken earpiece) and the thing has a broken USB port!! Not physically broken, but THREE different computers fail to properly recognize the device, already went through flashing the PD15IMG image just to see if it was a software problem on the phone, but no dice. Going to try once again when I get home with another cable and another computer. If not, I'm calling T-mo again!!! This is getting ridiculous.
[myTouch 4G Q&A, Help & Troubleshooting] lanternslight456:
Dude, that sucks, I'm sorry to hear this terrible luck
[myTouch 4G Q&A, Help & Troubleshooting] orangemonster:
This happened to me, i had royal ginger and clockwrk 3.0.0.5. Seemed to get this same error as everyone else when i chaged the setting in speedtest.net app. dont know if this was a coincidence but this is when my phone went to ****. now i am afraid to send it to tmobile rooted. but i was not removing royalginger when this happened.
[myTouch 4G Q&A, Help & Troubleshooting] faux123:
I'd ask for overnight delivery for their f*ck up... :) gl
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
the phone I got today was shipped through their "express" option(at no cost to me), I called saturday, they shipped it out yesterday and I got it today. The one ordered today was also supposed to be their "express" option, but they only said it will be here by Thursday. I doubt it will take that long. The one I ordered about a week ago was shipped "ground", but the label was actually for 3-day UPS, got it in 3 days exactly. This last one was called "express" but turned out to be UPS Overnight, so I'm hoping this next one is overnight too. Get this, last Saturday when I called for my second replacement, I asked what it would take to switch from the mt4g to something else, the girl told me I'd only have to go through one more exchange in order to qualify for a model switchover. She said it would be a "comparable" phone, but I'd only the the option of the phone THEY choose or the same one I already have. So today when I called, I asked the guy what phone I'd get from them if I wanted to switch and he said it would be the Motorola Charm!!! Even he said, "I wouldn't recommend that option", I was like "WTF!!", that's a HUGE downgrade. He transferred me to their "tech" support department and the guy told me to just try one more mt4g and then if that didn't work out we could "talk" about an alternative. At this point the only alternative I'd willfully accept would be the G2X, but I don't think I stand a chance in hell to get one from them. The problem is that's the only truly "comparable" phone they have, everything else would be a downgrade. Sucks that these last two replacements had the good screen, and it might just be my luck that this next one works fine but has a ****ty screen. I guess we'll see later this week how it turns out.
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
ok, now I'm just confused... I hooked up the phone to my laptop when I got home and the damn thing connected by usb just fine! Mass storage works, adb works... wtf??? I know I'm not crazy, I tried three different computers at work, two different microsd cards, restored the factory image via pd15img, and nothing would work. Now I get home and tried it on two different computers, worked perfectly fine! Now I'm debating on whether I should call t-mo and cancel the new order or if I should risk it and see if the replacement also has a good screen. Couldn't have been the cable I was using at work, it worked fine on the other mt4g I had on hand. This just doesn't make any sense, I can't duplicate the earlier symptoms. The usb jack doesn't feel loose on the phone and the cable I was using at work is almost new, and as I said earlier, it would work fine for the other mt4g.
[myTouch 4G Q&A, Help & Troubleshooting] saranhai:
yea i know i have this problem too..
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
did some more testing, looks like the cable I was using at work was defective, I brought my original mt4g cable from home and it worked perfectly on the same computer it refused to work on at work. Then I tried the "suspect" cable and it wouldn't work. I think I'm calling t-mo before they ship the new unit so they don't end up sending an unnecessary replacement. I'll do some more testing though.
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
ok, new development on the usb port situation. I got my second replacement today(I had called yesterday to cancel the shipment, but they said they couldn't cancel at that point, and I'm glad they didn't). Upon getting the phone out of the box my curiosity kicked in and I was curious to look at the usb port pins to see if there was anything that could have prevented my current phone from working with the usb cable I have here at work. The port on the new phone looked normal, so I grabbed my current phone and put them side by side to see if there was anything abnormal. Sure enough, my current phone had one corner broken off from the usb piece that has the metal pins, and one pin was bent back into the bottom of the usb port. I'm so glad they didn't cancel the shipment! Now I gotta make sure the new phone has the good screen and I'll be golden. For the record, I didn't break off the missing piece from my current phone, it was like that right out of the box when I got it delivered on Monday. Wow, I really lucked out on this one, as long as this new phone has the nice screen that is.... Probably would have been difficult to convince t-mo that the usb port was broken already when the phone was delivered, which it was, but it would probably be hard to convince them of it. I'll be testing the new phone later tonight to make sure everything is up to speed.

Sooo if u call t-mobile n say that ur phone won't turn on they'll just give u a replacement phone at no cost?
[myTouch 4G Q&A, Help & Troubleshooting] Don_Perrignon:
I think I bricked the SoB too... I was on Royal Ginger 1.6 just poking around to see. I went to restore back to Royal Glacier 1.3 using v3.0.2.4 and it never left the MT4G logo screen.

I took the battery out and wiped everything, tried again and nothing. Took battery out, wiped, tried to completely install a ROM, nothing.

Tried, wiping, installing, restoring, nothing.

BUT, then I got it to work. What I did differently wipe the order of the wipes. Usually, I wipe cache, dalvik (or whatever its called), then wipe data. The time I got it to work is when I wiped data, wiped cache, then wiped dalvik.

I don't know if the order matters or not, but it got it to work.
[myTouch 4G Q&A, Help & Troubleshooting] lanternslight456:
I think I can explain this.

Wipe Data/Factory Reset is an erase method but doesn't FORMAT the Cache. I believe if you format cache then wipe dalvik then do a wipe data/factory reset it leaves the cache unformatted. I've never heard of it being done in a different order than Data, Cache, Dalvik
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
I'm not going to generalize and assume that that's all there is to it, but at least in my case, I had bought the phone from them(through a contract extension) and it is still under warranty. The phone came out less than a year ago and there's a 1-year warranty on it, so every mt4g should still be within the warranty period. Yes, they did ship the replacements free of charge, the first one through 3-day shipping and the following two phones via overnight/next day. For phones bought on ebay or craigslist, that might be a different story but I don't know, some people report calling t-mo and getting a replacement without being the original owner. Doesn't hurt to ask.
[myTouch 4G Q&A, Help & Troubleshooting] saranhai:
So even after root I still have warranty?

lol I got my phone free from t mobiles smartphone sale during February
[myTouch 4G Q&A, Help & Troubleshooting] theghazi:
So final outcome. I had the gfree rooted s off mytouch 4g. Would not boot beyond tmobile screen. I send to HTC and they had to replace the board and send it back to me. Even though I had the custom recovery. Thanks
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
the phones come with a 1-year warranty, if it's rooted then all bets are off. They might or might not fix it for you. However, if you call in and say: "I rooted my phone, now it won't work", then the most likely scenario is they will tell you the warranty is now void.
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
congratulations on getting the phone fixed by HTC, that's a good ending.

So it looks like once the internal file system is corrupted and has the "can't mount cache" errors the only fix is to replace the motherboard.

Did u have to pay for anything?
[myTouch 4G Q&A, Help & Troubleshooting] warmonger26:
I had this problem. I gfree rooted, flashed newest cwm and then royal glacier. I did not partition sd card until, or tried, until after the fact. In rg I did not have wifi so I, under cwm, wiped caches, fix permissions and flashed rg again. Phone was looping on android/apple screen so I tried again but got all kinds of recovery errors. I tried to fastboot the pblabla.zip file but, did not have the part7..file on sd card. Got pu fail error, I think but then phone would not boot at all. Nothing on phone worked. Luckily I was within 14 days of buying phone so they exchanged it np.
[myTouch 4G Q&A, Help & Troubleshooting] saranhai:
is there anyway to buy one and replace it urself?

lol
[myTouch 4G Q&A, Help & Troubleshooting] erickdj:
maybe, but HTC would probably only sell it to an authorized repair shop. Still, why would you buy a motherboard? The phone should still be under warranty since it hasn't even been out on the market for a year and that's how long the standard warranty is from HTC.
[myTouch 4G Q&A, Help & Troubleshooting] saranhai:
yes... but doesnt rooting void the warranty?
[myTouch 4G Q&A, Help & Troubleshooting] serapisjay:
I'm in exactly the same situation as what you were. I tried PD15img in hboot and it stuck at the radio_v2. Nothing more I can do now. The biggest problem is that I am now in CHINA and it won't be easy for me to get another one from T-MOBILE. OH FML.
[myTouch 4G Q&A, Help & Troubleshooting] Pentlander:
Just wondering, did anyone actually figure out what caused the problem? I got a new phone under warranty and now I'm nervous about rooting it again...
[myTouch 4G Q&A, Help & Troubleshooting] Isubbie:
Basically if you have Eng bootloader and your original part7 file it is fixable. But I guess it was some glitch with clockwork.
[myTouch 4G Q&A, Help & Troubleshooting] TmpUsr:
No its not once you get failed pu its gone. I have been doing alot of work regarding this and more and more I see its gfree related as I see the ratio is higher on folks who do gfree compared to folks who just have S-OFF with eng bootloader.

completely wipe means? it will wipe internal memory also or just 2gb memory which installs programs?

Just the 2GB - effectively /system and /data. However, I'd always back up the rest just in case! :)

[Epic 4G Android Development] buggerritt:
Some users are noticing GPS issues after flashing to EC05. The issues include the inability to lock on satellites after extended period of up-time and terrible accuracy. The phone would have to be rebooted to get GPS working again. These issues are affecting users with stock and custom ROMs.

Following these steps will get your phone to a perfectly working EC05, with fully functional, bug free GPS:

1) Flash your phone back to stock DI18 via Odin (the .tar belongs in the PDA slot and your phone must be in download mode)

2) Follow steps 1-8 on this post.

3) Update to EC05 via OTA update or Flash Stock EC05 with Odin.(if you want to stay stock and unrooted, jump to step 7 after this step)

4) Install latest One click Root and Recovery + ClockworkMod v3.0.0.5/6 for EXT4 (optional) (Warning: this will format your NAND to EXT4 the first time you boot to recovery. If you do install this version, you must install an EXT4 ROM after booting to Recovery the first time. The stock ROM will not boot afterward.)

or

4B) Install One Click Root and Recovery + ClockworkMod v2.5.5 for RFS (optional)

5) Perform a backup, in clockworkmod (optional)

6) Install a custom ROM (optional)

7) Install all of your apps and enjoy a fully functional GPS

Calibrate your battery by following this thread (I suggest the second or third option)

I suggest to not restore apps from a previous flash. It might cause some issues. If you do encounter any issues, at least you won't have that to blame for it.
[Epic 4G Android Development] aero1:
Dont take this wrong but you are compelty incorrect. that particluar "old solution" was for the early test versions of eb13 froyo which had other different GPS issues from the cache issue. EB13 was actually fixed and had perfect GPS by the time of its official OTA.

What users (and Sprint advanced device) are seeing is a return of the assistance cache issue. All that flashing etc is obviously clearing the assistance cache which is why you had a problem and don't see it yet.
[Epic 4G Android Development] buggerritt:
You sir are incorrect. This fix was actually from DK28 (pre EB13). It has fixed my GPS. Perhaps your GPS has had no issues. If so, I am very happy for you. I never had problems with EB13. I did with DK28 and fixed it with this (while many others were still bumbling around and wishing for the official Froyo because they were scared to use a beta). Afterward my DK28 had perfect GPS. I also did with EC05. Others have had issues with EC05, as well. The problems seem to be from the same cache problem that DK28 had. If not, then this would not have solved the issues. I now get lock on satellites all the time and have accuracy of 1-2 meters.

I followed the steps over 4 days ago so, your theory on clearing the assistance cache does not apply.
[Epic 4G Android Development] buggerritt:
This was after over 9 hours uptime. The lock took 2 seconds for the first satellite and full lock on all within 10 seconds. Use of wireless networks disabled. This was not possible before following the steps in the OP. Previously, I was unable to get a lock after 3-5hours uptime. I would have had to reboot.
[Epic 4G Android Development] aero1:
OMG you are posting a copy of my fix from Sept and don;t even realize it!:eek:
[Epic 4G Android Development] buggerritt:
Please link me to your original fix. I would love to give you the credit for fixing my GPS, instead of ahmgsk, if yours is the original one. If you are the original poster, I find it very silly for you to deny that it fixes EC05 GPS issues, too. It does, indeed.

But, if you are referring to this thread, where

your OP states

:

"TESTED AND FUNCTIONING WORKAROUND:

Enter GPS debug/settings application by typing *#1472365#

click "Setup" tab

click "position mode"

Click "starting mode

Enable "Cold Start"

Back out.

Epic GPS will now call on data network for fresh valid ephemeris and almanac at every programing invocation of GPS and aGPS fixes will be very fast (usually less than 10 seconds)."

then,

it is not the entire workaround

. It doesn't mention anything about locking on satellites in each startup mode. It doesn't mention locking on satellites in any mode, as a matter of fact. It also doesn't mention anything about flashing any updates after the workaround. I hope your upcoming link, to the complete workaround that actually works, will shed some light as to who I truly owe my thanks and appreciation for. If it is you, then I will applaud you with a plethora of golf claps.
[Epic 4G Android Development] jdelano:
Hey there

I wasn't able to find whether the person you asked to do a nandroid restore; after Odin to DI18 steps to fix the GPS issue you were able to clear up.

Just today I have experienced what you describe. I've never had anything more than 4 minutes MAX to lock. I just tested and it didn't lock after 10 minutes.

Anyhow, did they restore or just do everything as stated in the OP??

Thanks!!

There are still no guarantees but, restore worked for this user.

BTW, mine is still going strong and it has been a week running. I always get lock within 2 seconds and always get 10-12 satellites within 10 seconds. Within 15-20 seconds, accuracy improves to 1 meter. This happens every time, whether I have just swapped my battery or if I've got 18 hours uptime. It makes no difference and I don't have to clear cached GPS data or download GPS assistance data. It just works every time all the time.
[Epic 4G Android Development] buggerritt:
I hope it works for you, too. Please post your results.
[Epic 4G Android Development] youngpro83:
Well like I said in the Midnight thread, I never had an issue with gps other than it taking forever to lock. After doing this I'm locked in in about 5 to 10 seconds at or around 20 to 30 meters. Its only a few seconds after that I'm locked at 9 to 10 meters. This work around has my vote of helping get a faster lock. I can't comment of any other results becuz as I stated my only issue was wait time with locking but now I'm locked in in no more than 15 seconds. That is faster than any. Gps lock I've ever gotten on this phone and I've had it since it came out. Thanks for this one once again.
[Epic 4G Android Development] buggerritt:

[Epic 4G Android Development] Cash Machine:
First of all, I appreciate this thread, the OP, and all of the suggestions listed here.

Unfortunately, I just thought I'd mention that I tried this fix [using the restore method], and GPS continued to crap out on me after a day or so--by which I mean it would become completely nonfunctional, without even an icon showing in the notification bar.

I am currently trying the "GPS crash" fix that was added to the following thread yesterday:

http://xdaforums.com/showthread.php?t=1029152

I'm hopeful about this one, as the explanation behind it seems pretty well-reasoned and thought out.

Hopefully the fix in this post will continue to help people, but I'm going on record as saying it didn't work for me.
