I have a HERM200 (TYTN HTC Branded). I definately have a hardware error that seems to be related to motherboard pressure. Totally took the phone apart - cleaned everything and reseated connections. I initially did have problems flashing a radio/OS Rom due to NO GSM errors - but I did get a complete working flash. For a week the phone has been sitting on my desk without a SIM card on standby. Power cycled it a few times and the radio will always come on. Can turn the radio on and off with flight mode. Always comes back. Turned on WIFI and Bluetooth no problems. Do have a Dpad problem where the direction button will stop working unless I move the scroll wheel. Other than that it doesn't freeze even under load and don't have white screens or no return from standby. So doesn't seem to be heat related - ie processor heat.
OK, put a sim card that works fine in a 2125 and I can make and receive calls. Did it for many calls last night - received and made the calls. Send text messages. Opened the slider several times. No problems. Battery was down so I charged it though a USB connection. Got the battery up to about 50% Still can make and receive calls doesn't seem to "hunt" for a signal which the phone would do if the radio was failing.
Removed the SIM card this morning and put the battery back in - received the first NO GSM after about a week. Removed the battery and touched the metal plate behind the battery and the GSM came back on bootup. The case screws are snug not super tight.
Is is possible that the motherboard is either faulty - removing the SIM caused it to flex or touching the battery back plate flexed or reconnected some chip.
IMHO the battery plate backer is WAY too close to the motherboard and is either putting undue pressure on the motherboard chips or when the battery is charging it somehow expands slightly causing pressure points. Seems like the battery backer plate is sitting directly on the chipsets.
Any thoughts - seems like there are way too many NO GSM errors for this phone.
same problem here probably
Same problem here... I've tried to flash the radio, but it stucks after a while..
Please help me, my Dopod 838 Pro has No GSM!
There is probably little you can do. Either the chip on the motherboard is fried or you did a bad flash. Explain the situation - did it just happen or did you flash something and it went bad. If it "just" went bad the radio is more than likely defective and no amount of software fixes will correct it. You will need another motherboard or a new phone. There are tons of articles about no GSM errors and sometimes it will come back but not for long. Known problem with this phone unfortunately.

So i see there are a few other threads but none that i found were quite like this. My phone randomly restarts and goes to the white screen that says stick together and won't load back up, also when i reset or take the battery out unless i have held the phone infront of my AC in my car or put it in the fridge/freezer it will not boot back up, it has heat issues but it's not actually that hot, i used to play playstation games and it would get much hotter and not freeze like this, it randomly started happening a couple of months after I got it.
it will freeze often in any temperature that is not considered cold, even in room temperature it will do it, any time i try to load my playstation emulator or use the internet it has a very high chance or resetting and not booting,
if the phone gets warm at all though it's a garuntee that it is going to happen, it just depends on when, i could just be finishing a call, sending a text etc, it will happen, and the only cure is putting it in the fridge.
i'm going to guess I have a virus of some sort or something really messed up in the ROM, but i've switched ROM's and it still does it,
should i do the SD card hspl back to SPL and try to find a legit original rom copy or is there a better solution for this? i.e deleting all my addons and going with a different ROM?
my rom history is TOUCH XTREME, Miri and Dinik(this is where it started) and now Energy(it is still happening here)
might be a good idea to go back to stock, though you dont need to remove hspl at this stage, just flash your phones original rom over usb, and have a real close look at the battery pins, they can often get bent leading to all kinds of reboot issues.
If its still the same under stock rom, then maybe remove hspl (no need for sd card flashing, can remove it using hspl2/hspl3(for tmous))
one of my pins was actually bent a while back! i bent it back to the shape it's supposed to be and used a safety pin to widen it back up so it looks like the rest, do you think that caused permanent damage? and if so is there something i can do to the pins to make it work right again? and not reset so easily
Well, i reflashed the stock SPL and ROM and yeah it won't even turn back on, just stays on the white stick together screen. it's done, being replaced by tmobile next week.
hmm, could be, perhaps if the pin is cracked a little, affecting power flow. not sure what to suggest.
I got the exact same problem as lllpulselll. I have already done a lot of things but none of them worked for me.
I did an hard reset
Tryed a lot of different rom's
Used the telephone al while without SD-card but still the same problem.
But I read somewhere that ik could also been your Sim-card, is that logic or not?
And by me also one of the pins by the battery is not right so I will that try to.
(Sorry for that bad English)
looks similar to overheating, you could install BattClock (it can monitor batery temperature) to check whether the self-reset happens at the same conditions,
had the same issue, finished with new mainboard (replaced under warranty),
during worst moments before repair I had to put my Leo in the fridge for few minutes before it could restart

That's probably it then, probably bent the metal things connecting to the battery and messed up the flow causing the battery to overheat or think it's overheating somehow. sucks that that is all that's wrong with it and it has to be replaced, wish the prongs could be repaired.

not necesserilly so don't blame yourself - mine had faulty mainboard (not battery) probably from the very beginning, but as it was purchased in winter, the symptoms did not show up until late spring, when outside temps grew
hi,
I'm thoroughly baffled here .... can anyone help please ? ... it's a long post I'm afraid, since I want to include all the info I can.
recently my beloved Legend suddenly decided it has no signal .. I get 'limited service' and the dreaded red 'X' all the time.
prior to this I had done no changes to phone nor had back cover off or taken the sim out. I have upgraded it to Blayos rom and all has been fine.
after some searching I discovered all the advice re bad antenna and a so called fix by shorting some terminals with a piece of wire.
(exactly which terminals was not made too clear though)
I am not sure though that I actually do have a bad antenna as I have cleaned the 2 under the bottom cover and 'lifted' the mating contacts ...
and have done the same with those under the camera cover.
one other thing I did was to circuit test all the 6 contacts in my phone, and they all 'ring out' ok ...
indeed they all ring out to each other, even with covers off, which suggests to me that there is a good circuit in the phone
still no service, but my GPS gets a lock pretty quickly, does it use the same antenna setup ? ...
I'm not even sure if it does really as I have read that phone will not work with bottom cover off, yet my GPS certainly does !
lastly I doubt it is the sim as it works fine in my wife's phone, but her's does not in mine.
over 190 viewings and no suggestions ...anyone please ?
in desperation I have changed my Radio from 7.13.35.05 to 7.13.35. 13 and got no improvement
Last act of desperation would be returning to stock...
If your not on airplane mode all the time I doubt this is a software issue.

Hi All
I know this is too late to post as Dell Venue is complete extinct in market but still i know many people own this device and love it
ISSUE
SIM card issue, Suddenly this phone pops up that SIM card is not inserted or unavailable, Network go away and automatically get resolved after restart or after re assembling battery.
RUMORS
Many people believe that this issue is happening because they loaded a custom ROM on device and THIS IS NOT CORRECT.
I own Dell Venue and facing this issue from last 8-9 months. I tried MIUI, CM7 various version but issue was always same..
Some people think its a network IC issue, That is wrong because phone can still show you available networks.
ACTUAL REASON
Dell Device motherboard doesn't have all the component soldered on it and they are just assembled in such a way that it stay in physical contact with motherboard, SIM card holder is one of them. SIM card holder is a small PCB placed over motherboard and pushed against motherboard with the help of its case. Once your phone is few months old or fell down several times, The body of phone becomes slightly loose and cause the issue that SIM card holder lose contact from main motherboard and phone pops that SIM card issue.
SOLUTION
1. UNSCREW your phone. There are 5 screws on phone. 4 are visible and 1 is under a white cap.
2. Open the case. Be CAREFUL of its small component and antennas
3. You will get SIM holder, Flash and antenna completely out of motherboard.
4. Now you will find all these components are connected to motherboard by golden colored metal (Like battery contact metals in every phone).
5. Use a pin and push all those metals litle out (like you used to do in your nokia phone when your battery used to loose contact with phone)
6. Clean all the component safely (Optional) - But i did because there was a lot of dust got collected in case causing it to get loose.
7. Assemble your phone back and tight the screws really well.
Turn on the phone and your phone is new again.
These steps will resolved WIFI and network issues as Antennas of phone are also connected in same way.
NOTE. Antennas are tiny metal plates placed under side silver plastic case. DO place them back else WIFI and GSM will show very low network.
I did this two weeks back and not a single time i got sim issue again, moreover my WIFI and GSM range is improved.
Thanks
Hope this will help.
I accidentally bumped a cup of coffee over on the back of my HTC Evo 4g LTE. I bumped a pillow into the nightstand while trying to contort my body in a way that would let me set sleeping my 10mo old into bed without waking him
I turned off the phone immediately, took off my Otterbox Commuter case (not the really waterproof Defender) and found a thin liquid coating on the back housing. Perhaps 1-2hrs later I made the poor estimate that it wasn't "that bad" and tried turning it on. The phone went into what I think was a boot loop (the display never showed anything, so I can't be sure), vibrating every ~30sec as it would if it were constantly trying to turn on and failing. It doesn't have a battery designed for removal, so I just had to let it sit.
Perhaps 6hrs later I went to check on it, and thought it was unresponsive after pressing the power button and nothing appeared to happen. I inadvertently pushed the volume rocker, however, at which point it made a beep as though it were adjusting the volume! After that, I noticed that the power button was also toggling the capacitive navigation buttons, which would illuminate and shut off as if the phone was "running" as well... but I still had no display.
Since then I've done a complete teardown (pop off all cases, separate all ribbon cables, vibration motor, speakers, camera, and removed the battery). I've done a few washes/brief soaks in isopropyl with the motherboard and then put everything in a vacuum chamber overnight at -20 inches of mercury. I also set the display and motherboard it in DriRite (lab-grate dessicant) for about a week now. In the meantime, I assumed the display may have been fried and ordered a replacement since it was only $28 on ebay. I just got it yesterday, but get the same results (phone "turns on," but display never lights up).
Any input on troubleshooting further?
- I've thought about looking at the two ribbon connector receivers for the display under a microscope to see if I can see any residue.
- I've also considered opening my wife's phone (same model) and swapping the batteries based on a probably false idea that if the battery might have gotten zapped, it could power the rest of the phone but not the display? Thinking not, as the power-ups I've attempted have had the USB charger plugged in, but easy experiment.
Would it be possible to short out just something related to the display on the motherboard so that the phone could run seemingly perfectly fine but just with no display? Just seemed so darn unlikely and that if I toasted some circuitry that a lot more would have been toasted in the process.
I plan to reassemble tonight and test for call reception (I think I can guess where the answer button is) and notifications (email myself and see if I get a vibrate/beep). That would confirm that the radios are also still functional.
Sort of at a loss and am not sure what else to do! I'm an engineer and even if the phone is toast... I'd really love to definitively figure out what's causing the issue.
Hi,
I've been having a somewhat mysterious problem with the wireless internet (Wi-Fi) signal on my SCH-1545, hopefully someone here can help me find a solution.
Details:
At rest, my wi-fi signal is weak, regardless of which network or router is producing the signal.
I use an oversized Anker 7800mAh battery, which adds a considerable amount of weight and bulk to my GS4.
I am currently running a recent snapshot release of Cyanogenmod (11-20140804-SNAPSHOT-M9-jflte). The last time I updated was few weeks ago, but my wifi issue began sometime early this week. Thus, it seems unlikely that the ROM is to blame. For what it's worth, my baseband version is 1545VRUAMDK.
Oddly, after some poking around, I've discovered that applying pressure to the back of the phone near the lock button seems to increase the quality of my wifi connection. For example, at rest right now my phone shows a 30% signal; when squeezed in the aforementioned manner, the signal jump s immediately to 55-60%.
I suspect that there may be some fault with the wifi antenna connector, or with the antenna itself.
My best theory right now is that a mishap or fall with this bulky battery installed may have delivered a shock to the phone's hardware beyond what it is designed to withstand. Consequently, it seems that the wifi system was somehow compromised. I've tried cleaning the wifi contacts as suggested here[1] .
Has anyone had this problem? Can anyone offer a solution?
I can't go on using my phone like this, and to get a replacement will be quite costly. However, if I do end up getting a replacement, I have my eyes on a LG G3
Thanks for your help!

Have your tried doing a factory reset? I know this is a pain in the butt but maybe it will put your mind at ease. Have you dropped the phone or anything that would cause the antenna to suddenly become loose? Is your connection bouncing up and down or is it consistenly just staying low? Also before a factory reset try getting Wifi Analyzer from the app store and check to see whats going on. Just sounds rather buggy that it suddenly started happening.
Same thing been happening to mine just recently. Seems like when I squeeze the battery cover the wifi signal is stronger for a limited amount of time.

If you squeeze your phone and it affects signals take off battery cover and try tightning all the little screws around the phone with the battery out.. might help just saying
Thanks for your suggestions folks, but I still seem to be in a pickle.

I tried a factory reset, didn't seem to help according to Wifi Analyzer (thanks for the app suggestion). As I said in my original post, I fear that drop may have caused this problem: since I use a heavy extended battery, I expect the damage caused by any fall would be magnified.

I attempted this as well - I removed the back cover and ensured all the ribbon cables and antenna cables were making a firm connection, and then I tightened all the cover screws. Nothing seems to have helped. Concurrent with my previous statement, I fear one of the modules (specifically the wifi/bluetooth SIC) on the motherboard may have become slightly dislodged from a random fall.
Does anyone know of a way I can test this theory or get it fixed if such is the case?

i'm in the same boat, my phone is exeriencing the exact same issue. I've got a new back plate on order, hopefully replacing that and the wifi/bluetooth antenna will resolve it.
have you had any success since this post?
