Bootloop (restart , only logo) lg e900 problem solved. - Optimus 7 General

If you lg optimus 7 e900 have this problem - still restart and only show lg logo , this mean that you phone have installed wrong radio firmware version . Newest radio firmware ( that support tethering ) have some bad structure and it is not hardware problem but firmware.
If you have enabled Pin secure code and enabled "automatic mode " in MFG at modem setting where you choose WCDMA and GSM band ,
phone will be restart after next turn on the phone . So you must install older firmware that have older radio firmware , of course it can be update to wp 7.8 ( tango ) . First install this older firmware :
LG-E900AT-00-V10c-268-FFF-OCT-07-2010+0_DZ_PROD.dz ( with lgdp2 v33 or v36 )
and you can update this firmware via Zune to 7.8 wp tango . This firmw. have not some languages but it is easy to install ( find oder posts about modification registry to change language ).
Second solution to fix restart problem - you can change Modem setting at MFG and choose yours band (your operator of course , for example orange poland - choose wcdma 900mhz , or 2100mhz , gsm 1800 or 900mhz , if you enable automatic mode and enable pin security for sim , phone will be restart again - bootloop problem ) .
Another solution is detachment upper (second) mainboard from primary mainboard phone ,and switch on the phone without this second
mainboard (wait 40 second , you see phone stop restart ) . This is illusion that problem is wrong upper mainboard .
Next connect upper mainboard to primary mainboard and switch on phone . If bootloop problem return , change modem setting at MFG
with your band .
Best method to fix - restore NV items , not difficult (see my another topic ).

Thank you!

thank you, i`ll try these method little later.

Are you trying to update on a PC running Vista?

HP RW6828 gsm module problem... need your HELP!

hello to all,
i have this kind of weird problem occurred with my HP rw68xx series. i received a call from a friend after our conversation was through my phone hangs on and i cannot click any key or ever tap the screen. so i let hang in there for about 2 minutes but when i noticed that nothing has changed i decided to push the reset hole below, after it boots up i noticed that antenna icon above has X on it, i checked on self test and found out that my "GSM MODULE" has failed its test then i ticked on PHONE and it shows "PHONE OFF" then i entered *#06# i was shocked when i saw that my IMEI is "FAILED".
now my question is Is there any way to restore it back the gsm services and imei of my phone? and what are the necessary steps to make it work again?
thanks in advance..
Same Case With me..
Plz Help.
BR
same here, it locked up solid, needed to remove battery.
powered on once. would not read sim nor would 'phone' show in wireless manager.
IMEI Failed etc, etc.
anybody got any ideas? is there not a driver of some sort that can be 're-flashed' on these phones?
new info:
self test also reports "fail rop1 iocontrol!!!" on the checksum test.
phone will only boot on AC power and battery can be removed and phone still runs!!!! unusual because my other rw6828 will not run on ac alone.
i believe that either the extended rom is corrupt, or there is a problem with the flash chip inside the phone.
it might be time for a JTAGging.
i've come to the conclusion that it could have a lot to do with extended rom.
is there a utility to flash extended rom via JTAG?
or, can i dump entire rom from working rw6828 and flash to stuffed one?
still no solution
i cannot work this one out on my own, any ideas?
Its all a bunch of numbers to me but :
set \HKLM\software\HTC\EngineerMode\BuildInEngineering ModeApp to 1
and dial *#*#364#*#*
And the GSM Test Mode menu appears
first dial *#*#364#*#*
if no network .... edit regkey as above mentioned

this also happened with my o2 xda flame. "missing wireless radio". updrading rom or whatsoever will never fixed this problem, it has to do something with the gsm chip, or on the hardware side. too bad maybe its time for you to replace.

[Q] Touch does not work after upgrading

Hi,
I've recently bought new wildfire (the second one for my wife , and had some problems with gyroscope sensor.
Then I've made an upgrade. Just as manufacturer recommends. I mean no rooting or installing custom ROMs.
Just going to "Settings -> About phone -> System software updates -> Check now".
upgrade took several minutes, but after restart the screen does not have any reaction when touching (can't even unlock to do anything else after). all other buttons (power, volume) work fine.
I tried hard reset from the recovery mode, as shown here: http : / / www . hard-reset . com / htc-wildfire-hard-reset . html , but still no effect.
now I have my warranty, and going to go to the reseller for consultation/fix.
I'm just interested doe anybody encounter such problem before me?
Thanks,
--
hi, yeah ive had this problem before but it was becuase i unrooted my wildfire with an old version of an WWE RUU on shipped-roms,
took me a day to think of flashing the newer version lol

[Q] Magic can't go through at the Gmail account initial screen

Hey guys
Recently I have bought an HTC Magic from eBay , it has a "T Mobile " logo at the top of it , so I presume it's the myTouch 3G version (That also what that appears at the opening screen) .
I'm locally staying in the middle east , the phone was sent to me from NY , it's an unlocked phone (according to the seller )
I have turn on the phone , insert my SIM card , but couldn't pass through the gmail account screen , I can't access google's servers , and therefore can't continue using the phone (can't keep going through that screen)
I was trying to change then network setting and changed it to my carrier , (I can't turn on the wifi too - if there is any way to do so ?)
I have download few Roms and recoveries and placed them at the SD card , while booting -( HBOOT) the device couldn't locate the Roms , and therefore couldn't make an installation of new ROMS
I have called HTC costumer care in the UK , but they couldn't help my that much.
Basically , what I was thinking to do is to try to wipe out the current operation system and install a new one , doing that using only the HBOOT menu , (I presume the phone is consider to be NOT rooted )
I'm quite newbie in this field , and I'd like to receive some advices cause I'm pretty stuck in with this ,
what shall I do next ?
Cheers
Shahar
Ok , I set it up
I have used a sim card with internet access, and set the APNs setting as well ...
