[HTC Sensation] jbthom4:
hey guys!

I have a bit of a puzzeler on my hands, hopefully you guys may be able to help me out!

I have the Htc sensation 4g from Vrigin canada

A few days ago i noticed that my signal strength was at 0, and i was unable to make any calls or surf the web.

So i go to virgin, and they set me up with a new sim (or three) to no avail.

I then call tech support, and they inform me that, simce my phone is over one year old, i cannot have the phone covered under the warrenty , no insurance me must fix the phone myself.

some information about the phone : I am s-off, running the latest radio (from here http://xdaforums.com/showthread.php?t=1202867 ) on android revolutions's stock ics.

I believe i have tried everything, but maybe i missed something, here is what i have tried:

remove battery

factory reset

new sim

update radio

update ril

update firmware

lift connectors on back of phone to insure proper connection to back cover

try new back cover

remove old sim/sd reader replace with new sim/sd reader

return to stock rom

So that's that, what do you guys think? Do I have a bad radio transmitter/receiver? bad main board?

Every thing else on the phone works, even the wifi and fm radios.

I have noticed that occationally the phone will show a couple bars, but upon calling it says that i am not registered on the network. most of the time the phone reads no signal no network provider under settings->about phone->network

I really appreciate any insight that you may be able to offer!!

Thanks!
[HTC Sensation] realsis:
So your provider is not willing to help? If you are paying your provider monthly and your device isn't registering on there network I would give them a call. Simply state your device is no longer registering on there network and ask them what are they going to do about it? I would be furious if they refused to help me because device is out of warentee! Sounds like your kind of stuck . You have tried everything. Perhaps give your provider one more call and see if they can at the very least trouble shoot your device. Just because your device is out of warentee don't mean you still don't pay them monthly for service. By chance have you tried a new sim card? Just a thought....I do hope you get this issue solved soon. Best wishes

[HTC Sensation] jbthom4:
thanks for the advice, I believe that I will give them a call tomorrow and see if there is anything that they can do for me...
[HTC Sensation] jbthom4:
ok guys, I managed to get my phone signal back up and going once again, but it was no easy matter. for those who may happen along from Google or what not, here is the solution:

Buy a sensation with a busted screen, remove guts, place in your phone, re assemble, make phone calls again.

I initially just swapped out the main boards, thinking that the problem was with the antenna connections or something. I put my phone back together and still nothing. deflated.

I took the phone back apart and swapped in the flex cable, antenna connector cable, and the board at the top of the phone. after putting it all back together everything worked, I'm thinking that replacing the top portion of the main board was all that needed to be done; I replaced everything just to be safe.

so there you have it, i hope this helps anyone who stumbles upon this with a similar problem. my problem was a hardware problem.

could anyone give me a clear explanation about swap. i found the term /cache and /system. i do not find any clear explanation about where the swap process takes places.

if i use swap2cache script, will the swap happen at sdcard or internal memory?

sory for noob question.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] pitchblack5691:
Swapping:

When the ram has very less free space the operating system moves the low priority processes from the ram and places them in the swap partition to make space for high priority processes .

When those low priority processes attain high priority the operating system moves that process from swap partition and places it in the ram.

This process of moving files to and from ram is defined as swapping and the partition which is used for storing these swapped files is the swap partition.

/cache is a partition which is utilized by programs. Programs place their files which are routinely used in the cache partition to reduce the processing time.

For example:

Gallery app saves all the thumbnails of all the pics and videos in the cache partition for fast access when the app is opened.

/system is the partition where all the operating system files are placed . This partition contains nothing but the files which are needed for the operating system to perform without any intervention by the user (both cache and system are generally write protected).

For example:

The folder C:\windows is the system folder in windows whereas /system is the system partition in android.

When you use the /cache partition for swap space you are using the phone memory and not the external memory.

you might want to google the term "zram" it is some what faster than swap to cache,

it compresses the ram memory and makes way for new processes and when the compressed memory is needed again, it simply uncompress them right in the ram memory. as it works with the ram memory itself it is considered to be the fastest.

(please correct me if I am wrong)

And don't be sorry for a noob question. Every experienced developer must have started as a noob and we are here to learn and share so questions are always welcome!

great explanation brother, the only bad swap, in which damages the lifetime of sd memory, I remember when I used my old w8 swap took longer to copy files from PC to phone and vice versa, so I do not recommend doing swap is my simple opinion :highfive:
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] pitchblack5691:
Swapping to external memory is never recommended unless you badly need swap partition and it's the only option you have. Swapping to external memory reduces the life of the external memory very quickly since swapping pages to and from external memory increases the number of read/write cycle count of the external memory which is a very important factor in the external memory's life.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sony_84:
so, when we use swap to /cache or /system , will it reduce the life of our internal memory ?? it means that it will break our gadget someday
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] pitchblack5691:
Theoretically yes,

It depends on how often the swapping takes place and practically in very extremely rare cases the internal memory fails due to swapping. (someone correct me if I am wrong)

External memory is designed in a way to have large space so it's transfer speed is the lowest.

Internal memory is embedded flash memory and has lower capacity compared to external memory and it has higher transfer speeds compared to external memory.

Ram is volatile memory designed for high speed data transfer.

If you are very much concerned about your life of external memory and internal memory then zram is your only option.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sony_84:
if it's so , I just need to apply zram script ?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] pitchblack5691:
yes.

this is the script to be executed to enable zram.

i guess it should work with all kernels for our device (i guess)

i took it from rage kernel thread thread so the credits goes to DuMOHsmol

the script must be run at boot every time (copy it to etc/init.d folder)(provided you have init.d support).

HIT THANKS IF I HELPED YOU! :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sony_84:
this is working great.

just to make sure, is this safe for internal and external memory??
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] pitchblack5691:
Ya man! Nothing to worry. The main concept behind zram is to optimize the ram memory for system on chip devices (devices whose hardware can't be upgraded).

Hi, it is sad to say that just after I got my new Desire C it hanged. Could not get to know what happened with my device. Last time I played the music from my device by connecting to home theater music system. Suddenly the music stopped and found that My device is dead. I tried booting it many times, but not able to do so. It has been given for service now. I just want to know what could be the cause for it to be dead. Thanks all.
[Desire Q&A, Help & Troubleshooting] skeathy95:
Sounds like you have blown the headphone jack in the circuit board, I play my music loud on my HTC EVO and its blew up with the power from the home system was not design for a small device eg phone, iPod

[HTC One S] pookipsy:
for a few weeks, my one s battery cant pass through 2-2.5 hours of screen time although it used to be something like 4 hours.

i tried to full reset, didnt help.

even noticed that games are lagging, like music hero and subway surfers to the point it can fail me.

most of the time the screen brighness set on 30%, wifi mostly off, gps off, sync off. only 3g is on.

i got s4 version running 2.21 software stock locked unrotted nothing.

as it is from the manufacture.

i dont use alot of apps, mostly basic ones like whatsapp chrome shazam and few more.

i dont think its some bad app which draning my batt, also the phone is 2 month old.

all this time, the phone didnt do any problems but 2 days ago for the first time after unlock the screen phone had restart.

could it be that after 2 months my battery is dying?
[HTC One S] nor-ric:
If you say that games are lagging there could be something draining your cpu... This could also explain the battery drain.

In the battery stats, what app/task is draining most?
[HTC One S] pookipsy:
Well, screen by far... No special app drains..
[HTC One S] el_smurfo:
Try turning down your screen brightness.
[HTC One S] lorddart:
If it's really bad I'd try a reset
[HTC One S] Hunt3r.j2:
BetterBatteryStats and Carat. Take a BBS dump after a day's use and you should see what's causing major issues. Carat will take care of anything else after a few weeks by showing you what apps are using serious battery power.
[HTC One S] inetdua:
it is unlikely that she dies. What radio are you using?

[HTC One S] MrThreeChains:
Why dont you install a Custom ROM for testing if this problem still shows up ? Like someone mentioned above something is fu*** up your CPU for some reason and this is the reason why your battery is going down very fast.

Some questions:

- Do you run any "battery saver" or any other app in the background (except Facebook,WhatsApp,GMail,..)

- Do you charge your battery from totally 0% (when your phone doesnt boot anymore) to full 100% ? It could be a battery de-calibration but this not really explains your lagging problems
[HTC One S] pookipsy:
i dont want a custom rom because i still want my warranty.

i dont run any battery saver app in background.

i charged the phone from 0 to 100 few weeks ago.

for 2 days im trying to be on gsm only and its seems battery have been improved by almost an hour.

there are less lags in games also and the device is feeling faster.

could be a radio problem?

i have full reception most of the time.

maybe the diztronic skin interrupting radio or something?

in few days carat will give me a report and ill see what he suggest.
[HTC One S] MrThreeChains:
I understand your argument but if you follow the guides step by step you will succeed. Even if you fail,you still have multiple ways to recover your phone. My broadband chip was broken and i lost my IMEI (Galaxy S1) and i had a custom ROM installed and the support still repaired it.

Maybe you need to calibrate your battery. If you only charged it once it doenst really helps.

Dont know,maybe it could be a radio problem.

You have a skin installed? If you rooted your device the warranty still could be gone.
[HTC One S] pookipsy:
i dont want to root the device cuz of warrenty.

i have diztronic case from amazon.

and i heared recharging the battery from 0-100 could harm your battery for long term and shorten the battery life.
[HTC One S] usaff22:
No. I don't know where you got that from but It's crap. It doesn't harm your battery, in fact it is better than charging from 60%.

GSM only does NOT affect gameplay. Maybe battery, but not gameplay. Somehow I think you're trolling everyone.

Sent from my locked, tampered ville
[HTC One S] pookipsy:
im not trolling, i love this phone and really wondered maybe i did something wrong with it..

gsm only shouldnt affect games but maybe its affecting something else which affect games.

maybe its a software issue or drivers.
[HTC One S] Hunt3r.j2:
Guys, stop being idiotic. "Battery calibration" might as well be telling the person to charge the phone while hopping on one foot and rubbing his other.

It's quite simple. Post screenshots of the top of the list for partial wakelock, process, and kernel wakelock. This will help diagnose battery drain problems. Carat will slowly build a list of battery drainers that you can also use to identify issues.
[HTC One S] Untouchab1e:
And please make sure you're not using any task killers or similar apps as they cause more harm than good and are big no-no's on Android.

Speaking of Custom ROMs, I'm not sure what the rules are where you live, but where I live, unlocking the bootloader does not void the warranty, so flashing custom ROMs is perfectly safe, just make sure to make a backup first.

And yes, battery calibration is not possible, as these batteries doesn't have any "memory".
[HTC One S] pookipsy:
Where i live the warranty void sadly.

Im still waiting for carat report but for this moment, using gsm only + wifi instead of auto wcdma/gsm, seems to make my battery life normal - almost 4 hours screen time.
[Samsung Galaxy Player 4.0, 5.0] joethaking06:
ok when i plug my player into my laptop, the laptop makes a sound like it knows its plugged in. I have all the drivers installed and never had an issue before but now it shows up in device manager as an unknown device with the yellow triangle. My player won't even show that its connected to a pc and i can't mount it. It also doesn't acknowledge when its plugged into the charger. if I turn it off and plug it in, it just comes on. It used to go to the battery charging screen and i would have to manually turn it on. the fact that my laptop acknowledges that something is plugged in makes me think its not a hardware problem and the fact that i take really good care of it. any ideas??

I'm on genericginger btw
[Samsung Galaxy Player 4.0, 5.0] DZonikg:
And you developed what so U open thread in development section
[Samsung Galaxy Player 4.0, 5.0] aznflawless:
Wrong section.

is this only your laptop? Does it work on other computers?
[Samsung Galaxy Player 4.0, 5.0] joethaking06:
sadly i don't have another computer to try it out on. but right when i read this i plugged it in my xbox and it started charging.... and it still won't charge with the wall charger

sorry about the wrong section also
[Samsung Galaxy Player 4.0, 5.0] atcq28:
It may sound stupid but turn off your player and turn it on again. This happened to me once and that did the trick
[Samsung Galaxy Player 4.0, 5.0] joethaking06:
that was my first thought but it didn't help. it won't even mount in recovery mode
[Samsung Galaxy Player 4.0, 5.0] joethaking06:
ok i just tried it on a friends laptop and it shows up as unknown also
[Samsung Galaxy Player 4.0, 5.0] omaroe666:
try deleting it from your laptop and let it install again worked for me : )
[Samsung Galaxy Player 4.0, 5.0] joethaking06:
it always shows up as unknown... just did a full wipe and reflash and nothing has changed :(
[Samsung Galaxy Player 4.0, 5.0] tim1089:
Have you installed Kies. You can use the reinstall the driver option. Another thing is while it is plugged in uninstall the device in the device manager. Then unistall everything under you universall serial bus controller one at a time. Then click on the action command at top of menu bar and scan for new hardware.It will reinstall the usb hubs and root hub. Make sure your player is unplugged when you do this. Then reinstall the samsung usb drivers then plug in after everything is done.
[Samsung Galaxy Player 4.0, 5.0] Silvrsun:
Exact same thing happened to me. Try using a different cable. I used a different cable and it started working normally again. Remember to plug it in and out slowly to avoid damaging it.
[Samsung Galaxy Player 4.0, 5.0] alljokingaside:
One easy thing to check for is whether or not the PC detects the player. Assuming you have Win 7 (the steps for Win XP is nearly identical), right click on My Computer and select "Manage." Go to "Device Manager" and find out whether or not your devices is listed under "Universal Serial Bus controllers"

I had this problem happen to me before and the first step in its solution was going here. (The rest of the info is on multiple threads around here)
[Samsung Galaxy Player 4.0, 5.0] joethaking06:
ok i tried uninstalling it in device manager and reinstalling the drivers with kies but it still registers as an unknown device. i tried 3 different cables and so far the only way to get it to charge is to plug it into my xbox while the the xbox is off.... i can't get mass storage cuz my player doesn't recognize its connected to a pc... it doesn't acknowledge when i plug it into the wall charger still. the last thing i remember doing before this happened was i installed minfree manager and used some settings i found on the internet somewhere and then i deleted the data to Wild Blood and uninstalled it because i couldn't get it to run without lag
[Samsung Galaxy Player 4.0, 5.0] alljokingaside:
what drivers are installed? it'll tell you when it tries to check for drivers, checking off what you have and what driver-installations failed, if you check for it in the lower right hand corner
[Samsung Galaxy Player 4.0, 5.0] joethaking06:
ok i charged it to 100 percent with my xbox and now it will at least charge when plugged into my laptop but not mount. it still doesn't charger with the wall charger either. i have no idea how to check what drivers i have installed. i assume they're right because i downloaded the kies from the samsung website as it was the only download option for the yp-g70 ... i've uninstalled the "unknown device" repeatedly with no luck. i even tried to update the drivers and point it to the usb drivers folder in the kies installation folder and it still doesn't work... idk what to do...
[Samsung Galaxy Player 4.0, 5.0] gspuser123:
At least you can charge mine won't charge using anything I'm down to 15% I don't know what to do, I'm having the same problem as yours ima try using my ps3 to charge

Nothing with the ps3 my galaxy is gonna die ugh

---------- Post added at 01:30 AM ---------- Previous post was at 01:19 AM ----------

If this helps when I plug my galaxy in the wall charger I hear a noise coming from the charger like white noise and when I plug it out the sound goes away
[Samsung Galaxy Player 4.0, 5.0] alljokingaside:
Well, I had the exact problem a few months ago and fixed it. Disclaimer- low-medium risk. no responsibility here

I'll give you the condensed version, since the whole is posted elsewhere. after deleting the existing drivers from the laptop, I plugged in the SGP. in the icon tray, the lower right corner, there's this gray box that appears with circular, moving arrows. Right click to see what's being installed. It's automatically connecting to your USB device and searching for teh drivers. every driver but the Mass Storage driver (I forgot the exact name of the file- MTB comething?) installed properly. from there I went to the device manager and found option under the USB controller in properties to fix the problem. took me a few tries.
[Samsung Galaxy Player 4.0, 5.0] omaroe666:
i mean delete your usb files on your laptop when you plug it in it will install the usb drivers then it should work again : )
[Samsung Galaxy Player 4.0, 5.0] joethaking06:
thank you everyone who helped i'll make sure to go thru and click thanx for all of you. especially since this was the wrong place to post this. i finally got it to work. i noticed that my usb cord smelled like my cologne and so i wiped it down with alcohol and a qtip only to see the qtip turn green. from there i knew there was corrosion involved so i followed the instructions in this thread http://xdaforums.com/showpost.php?p=30778095&postcount=1 and now everything is back to normal :) so again thanks everyone!!

[Motorola Droid 4] terinfire:
At present, we have topics every few weeks or so with someone new, coming to ask if GSM works in America. Then, someone wants to help and try to figure out why -- but there is no consistent thread for this. So let's use this.

Does the Droid 4 work in the US on GSM yet? NO

This is to be used as a master thread to post research/thoughts/findings. If anyone has any clever thoughts, please search the thread first to make sure it hasn't been found yet.

What we do know is that with OTA ICS from Verizon, the Droid 4 supports GSM for *OTHER* carriers outside of the US. There could be any number of reasons that it does NOT work. As a quick run-down of the problem, I'll identify where the primary issues could be and allow for anyone else to build upon it, ask questions, and discuss.

The Radio Firmware

-- The firmware for the radio itself could have a lock or a setting that needs to be adjusted and all data requests are blocked through this.

RIL

-- The interface between the radio and Android -- there could be a software lock here that restricts specific carrier ID's.

ROM

-- The ROM itself has a baked-in block for GSM in America.

The best thing we can do is to try and identify or step through the stack (if such is possible -- I'm a developer, but not for Android) and see WHERE the calls break at.

--If it is a software lock in the ROM, then aftermarket ROM's like CyanogenMod should allow data to work in the US. If we're not seeing this, then this is likely not the case.

--If it is a software lock in the RIL library, then we'd have to have a reverse-engineered library (which could be very difficult to do). We should be getting some kind of error somewhere in here. At this point, though, it's hard to tell if the Radio Firmware or RIL is the actual problem.

Anyone with any background on this, please feel free to contribute. correct, and update. I'll try to get back here and update this master page as I see responses further in the thread.
