[myTouch 4G Q&A, Help & Troubleshooting] ibrokeditgood:
whats with the mt4g's?

Ok, so I guess I should start out with a little background.

I am familiar with this particular phone, as I bought it from a friend of mine. It used to work like a champ. not so great on the battery, but it was a beast. Would wifi tether with my old phone,laptop,ps3,tablets,etc...never a problem.

So it got dropped, screen got busted up. I bought the phone, went and had a new screen and glass put in.

Went and bought a 16G hdsd mini for it. Gave it a good ol' factory reset to clear all his old data and whatnots out of it.

Ok, so far so good. everything except the wifi and wifi tether worked. The icons would blink on and off, and both would eventually say "error".

No big deal, (actually, it is, I actually need those two things working) , but I still have my old phone to use for now when I need to tether.

(its a sad work around,but what can ya do?---I'm starting to look like a "dealer" with all these phones laying around..lol)

Well, earlier this week, it started to reboot for no apparent reason.

let me say this before i continue:

S-ON

NOT rooted

NOT unlocked

Not anything- it's ALL stock trim. and I cant remember if usb debug is on or not, or what my usb settings were, ie,charge only,pc connect etc.

anyhow.......I was getting annoyed with the rebooting thing, so I popped the SIM and used my old phone. (which is unlocked and rooted,and old-yet brand new--[old model wise-new store wise] ) and guess what? Old faithful started to act the SAME WAY!!!

All this lasted about 6 or 7 hrs between the both of them, (odd? very. could understand one doing it, but both? only thing the same between them is the SIM card. different mini SD's .....) Relevance? Unknown, it's just what happened....

ok, so all a sudden, old phone just , acts 'normal' again...so I went back to the mt4g. It acted 'normal' once again as well, still with same wifi issues...so...'normal', i guess for now. No more weird reboots....

So I finally decide its time to get some new goodies under the hood ( ROMS ROMS ROMS!!!!!) :D

And after weeks and weeks of reading here and on other forums ( this is my fav! this site has helped so many times, I cant tell you, smart ,talented folks here....bee's knees, man! )

So I have adb installed, several different sources of driver files for usb (downloaded)-(didnt get the scence software or drivers as of yet though)

Have several "newest roms" -ie the 2.3. whatever with the 0.89.0006 hboot (the last ota update from t-mob for these phones) .

Needless to say I was, and -am- ready to bite the bullet and start tweeking this thing.

So I pull out the SD and the SIM, swap phones again, go to start up the mt4g to get my settings in order (double checking), and guess what.....

BOOT LOOP~~~~~~~awesome.....i think i scared it....:eek:....i would get past the first boot screen, and get to the animated 2nd screen, then reboot would hit,....then, slowly...over the hrs of pulling the battery and restarting and such...no more 2nd screen...it sticks and hangs on the first boot screen...lovely....:mad:.....ok, so i do the VOL down and Power, get to the hboot menu..."hey, lets factory reset!" .....:rolleyes:...uh, I SAID "RESET!" ......yeaahhh,no.:eek: ReAlLy?

It freezes on factory reset,

it freezes on fastboot - reboot bootloader

it also freezes with ruu.exe and with adb fastboot reboot command.

it WILL work on a 'reboot' only, (as in, it will reboot,and not freeze out of the menu)

it attempts to look for a restore image before the menu selections become active when entering hboot as well. (where did it go?!? 2nd hand phones, i swear:rolleyes:)

ok, so I had to follow a tip to modify a couple lines in the *.inf file with the hardware id to get the drivers to actually install for adb. Now, it picks up the phone, says nothing about mt4g or anything, says Android 1.0 when connected.

adb commands --well,.....it knows "something" is there, but my queries return little to no information. (as in the "ruu" check to unlock, via the htcdev method -but lets not get ahead in the story.)

So I have attempted to do the factory reset several times, 98% of the time, i get a freeze, BUT- a few times I got the phone icon with the yen-yang style green arrows and then a shut down with 7 to 8 vibrates- ( yeah, a bunch back to back so it was hard to count, but it is 7 or 8 times), and a couple times i got the "!" in the triangle , with a "freeze" (nothing really worked,let it sit for about an hour and a half-pulled battery)

Now as for the hboot trying to find a restore img, I placed the "new 2.3.x" rom(s) with it correctly named <---:D , no extra zip.zip's or ANYthing like that...I typeded it in goods! :silly: ( no, really i did ) the PD15~whatever...sorry,i'm exhausted....

And it says every single time, older version yadda yadda......ug! is it me? or are a LOT of these roms not named 'correctly'? (just wondering-see a bunch of people have the same problem, and the usual response is to just re-download---i passed my quota in a day and a half, trust me, i've downloaded, and redownloaded and downloaded more/others/here and there/ high and low, last on was from 4shared from a link here, and it just fell flat about 20 mins ago when it was about 75% done....well, that was a first, and that is well, cant say here because it's not a "polite" thing to say.....:mad: or scream, actually......but thats just me complaining , no relevance......

So what am I to do in a situation like this? I've heard 3 vibs means its "bricked", i got 7+....I can still boot hboot, and fastboot. Is there hope?

ok, so to recap, cant push with adb so far, all roms/backup/img/zip files downloaded are older versions and wont load. Ruu app acts like it sees the phone,i go thru the prompts, then it says, waiting reboot bootloader.....freezes phone, and does nothing....reset factory - freezes phone, reboot bootloader - freezes phone from the menus on the phone.

Since all of the posts about this phone, HTCDEV says it has a way to unlock these phones, but I "supposedly" need to upgrade the hboot-I'm guessing, cause the whole ruu thing. So, that is the way I was thinking of going-IF I can ever get it to act right...

As a last resort, I called the Doc' (locally) to find out how much a new logic board would run....well, it's cheap enough, but c'mon..where's the fun in that? (small parts and shaky hands, have to get the doc to perform the surgery anyhow...)

recap on the settings:

S-ON

Not rooted

Not unlocked

USBdebug in OS: unknown

USB connection settings [power only-connect to pc] : Unknown

has the LAST OTA update from t-mob / has been factory reset twice (successfully) since i've had the phone .

the hboot screen info is as follows:

Glacier PVT SHIP S-ON

HBOOT - 0.89.0006

MICROP - 0429

RADIO - 26.13.04.19_M

eMMC - boot

Jul 15 2011, 16:45:17

only other info i can offer up is the crc, which is as follows:

IMAGE CRC

Osbl : 0x8AFE4E12

amss : 0x2AB26270

hboot : 0x17F8232C

boot : 0xFB35CCBF

recovery : 0x87638ED8

system : 0xF75E59F

I'm open to suggestions......really not in the position to spend anymore $ at the moment, although the replacement is "cheap" , that would rack up about 200$ +/- invested in this phone so far, with the buying price and new screen and glass and labor......I know it's not dead yet....YET.....:p.....and I KNOW it's got to be something simple I've been overlooking, (high probability-as, that's, the 'norm)

So, c'mon you mad scientists!!!!!! help me if you can...after all this reading lately, my brain is like a toilet bowl full of alphabet soup......

This has me stumped so bad, i actually had to register and post here for the first time :o , but like i stated before, this site and the folks here have helped me so much with other issues on different phones, for a good long while now....:laugh: :good::good::good::good::good:

while i wait for a reply....i guess i'll restart that last download......:( .....another 300+Mb at 8 to 20kb/s ....yay! (sad thing is- i havent even been capped yet!!!!! quota is almost hit.....wow, the rest of the month is gonna be :pthupppppppttttt!:p oh well, use whatcha' got.:cowboy:

So I'll go ahead and say thanks, and sorry....Thanks for the help, sorry for the headache I'm about to cause ya ;).
