Issues with my HD2 (Optus Australia - Italian Fone)

Been having some problems with my HD2 as of late. If this is the wrong forum to post, please point me elsewhere.
Purchased original one via Mobicity - turned out it was a HK version. I dropped it and smashed the screen, so got a replacement one (purchased thru Mobicity again) under my insurance.
Not sure the origins of the second fone though. When it arrived, it was in Italian. Had to send it back to M/City to reflash it with (what I believe to be ) a WWE version.
Details on startup screen:
R 2.00.51.07
G 15.30.50.07U
D 1.66.76641
Have left the phone as-is after it was reflashed with an English ROM and returned to me. Has worked perfectly for about 8 months. Recent issues only occurring last 2 months or so.
Issues having lately:
* Randomly reboots itself - completely randomly. Sometimes, while not even touching the phone, sometimes while typing a text or browsing the net.
* Battery usage lately has been horrendous. Hard to pin an exact figure on it, but it's MUCH MUCH worse than usual, over the last 2 months.
* CONSTANTLY dropping signal & Data connection. I can watch the data/signal symbols switch from nothing, to G, to 3G, to H, and back again within the space of seconds. On occasions, when the data-conn drops out (but fone signal remains), I go into connection settings and find the Data Settings slider is switched off! I must manually go and turn it on again... which sometimes works, and sometimes fails to stay on.
I HAVE manually gone into the settings and told it to update to the latest data settings from my provider (Optus) and it always responds that I already have the latest settings.
Often, the only way to get data connection back is to manually reboot the whole fone.
Sometimes, while browsing a simple website on the fone, it will drop connection. I live in Brisbane. Optus advises Brisbane has absolute FULL coverage, until you start going outskirts. I can be in the city centre gardens (no big buildings to block signals) and still not achieve full "H" or even "3G" speeds... most times only achieving simple "G" speeds.
This is obviously not right I HAVE contacted Optus about this, and they suggest it is an issue with the phone, as they insist they have full coverage brisbane-wide.
I have also noticed, in the last 2-weeks or so, that Cookies Home Tab is not working correctly all the time.
On occasions - but not ALL the time - on my home-page CHT displays appointments that are already passed days or even weeks ago.
Sometimes, when adding a new appointment (either manually in the fone, or via the MyPhone website and synching), it will not display at all in CHT.
I know there is a new version of CHT, but some of the technical info on the website sounds like there can be issues with not correctly un- or re- installing it.
I've still got a couple of months left for my manufacturer warranty.... I'm not keen on reflashing with un-official ROMS until after that period has elapsed... then i'm keen to go for it. If that is my only option, then I will consider, but would prefer a "genuine" fix first.
Can anyone please offer some suggestions, hints, experiences ? I haven't been on the forums for months, and now the HD2 thread is some 10-episodes of 30+ pages, so I have no hope in hell of reading thru all that hoping to find an answer.
Suggestions please for possible reasons, or fixes, or a different WWE English ROM to flash to ?
Note also: My serial number does not appear to be Asian in origin. I have tried to d/l the Asia Pacific, the Worldwide, and the HK latest ROMS... but it fails upon serial number. I have not tried, but I assume my fone is Italian model, hence any ROM that I flash must be d/loadable from another source, not the HTC website.
Please also note: I'm not - at this point - interested in running Android, so (without wanting to sound ungrateful) if any help could avoid suggestions of that nature please.
Thanx in advance for any assistance.

Hi, I to have an HD2 in Oz from Mobicity - though never got an Italian version. To be honest, the only time I had an issues like those you are talking about was when I flashed new roms WITHOUT 'Task 29' first. Look it up. It kind of "cleans up" your phone inbetween cooked roms. But as you have only had Official roms on your phone, this might not be the issue.
To be honest, I don't think you Task 29 anyway until you put HSPL on your phone (this allows you to put cooked Roms on), but as soon as you do this, you void your warranty. Now you can take HSPL off before you send it back, but if your phone was to die BEFORE you took it off and then you sent it back, you'd be ****ed if they managed to power it up.
As you're under warranty, I'd send it back to be fixed and explain the fact that they had another rom on when you first got it.
Ra-ey
ps. You may want to quickly check online to make sure you are running the most uptodate Rom for your phone on the HTC website.

Hi,
Did u try hard-reseting your phone by pressing the volume up and down and the power button at the same time. Usually fixes many issues relating to yours. It might have been caused by a programs problem which corrupted main system files.

Thanx guys for responses.

Not yet, no..... will go through that process tonight. Was just worried that hard-setting it MAY end up back with the Italian settings (on the off-chance it still has an Italian ROM, but has just been set to display in English) ???
Can anyone identify the ROM details in my original post, as being WWE (I assume this means World Wide English?)
I cannot find anywhere that lists if those numbers mean WWE or English ?

Further to this... i just found this thread here: http://forum.xda-developers.com/showthread.php?t=791436
This is almost exactly what my phone is doing too, so I suspect it may be the same cause.
One thing I forgot to mention in my original post here, is that sometimes, after the fone reboots itself, it fails to boot up again and all the handset buttons fail to respond. The little red reset button does not work either.
Doesn't happen EVERY time, but occasionally, the only way to resurrect the phone is to remove the battery for 30 mins or so, then reinstall and try again.
Obviously a very real issue - and it seems a known one - perhaps time to return for warranty fix or replacement.
Thanx all for responses in this thread - I will monitor the other thread now for further news.

when you hard-reset it reverts it back to the last rom you had, if it was WWE then it would reload that.
Remember when someone load's another rom on your phone it complete (kinda) erases the old rom and replaces it so there would be nothing that would revert it to the italy ROM.
R 2.00.51.07 (Radio Version)
G 15.30.50.07U (Protocol version)
D 1.66.76641 (ROM Version) could be anything
Usually the Italy ROM only has one language in the rom so my guess would be it has the WWE, by looking at the numbers above no-one would be able to tell you what you what rom it is.
Hope this helps

Thankyou mate.... that makes it a lot clearer
Will try the hard-reset method tonite and-reinstall only the apps (if it ok to use that term, for WM programs !!!) that I need.
Have also been given a link to the latest WWE ROM to flash, from Mobicity, so will hard-reset, to clear any crap, then re-flash with the new ROM.
Just curious... I know I should remove the memory card when resetting/reflashing (i'm not doing dual-boot with Android), but should I also remove the SIM card too? Eg: Get the background system installed and running, then power-off, insert SIM, power-on to get the network specifics up and running ???

My Guess
I have a Telstra HD2, running the latest Telstra ROM and CHT 1.8.5. The phone reboots regularly of its own accord. Seems to be related to overheating as the base of the phone is quite hot when it reboots. If the phone get really hot, it will not re-start (stays at white screen). Have had to put the phone in the fridge to get it to work.
I don't know if this is related but I have a cradle that I use to connect my HD2 to my work PC. If the HD2 is running SenseUI, after the HD2 was been in the cradle for a while, the HD2 re-starts. This does not happen if I disable SenseUI. It seems that the restart only occurs after the battery reaches 100%.
The restarting occurs with CHT 2.0 beta as well.
When I get a chance, I'll do a hard reset and see if that fixes the problem.
Cheers

Hmmmm....... seems to be a recurring issue with some of the "newer" phones. My original phone - before I dropped it and smashed the screen - never had any of the issues I'm currently experiencing
I've read somewhere on here that the rebooting issue is suspected to be from early-production snapdragon processors..... which SHOULD be an immediate warranty claim, in my opinion.
I will try the hard-reset, and then a fresh Official ROM install, to see if it solves it.

[Q] Clock Setting Back to Default 1/1/2009 After Restart

My Acer A500 always resets the date & time to 1/1/2009 when I restart it. But yesterday when I checked with my friends A500; that isn't the case. His tab had the correct date and time after restart.
Can anyone tell me if there is any internal battery needs changing?
"Restart (Offing the tab waiting 10sec and starting it up again)"

Is your tablet encrypted?

Nope. It is not encrypted.

I was looking at the internal breakdown, and I didn't see an internal battery, other than the main battery. Not like you would see on a PC for example.
Probably, because the newer hardware uses Flash memory, unlike PC's in the old days, which relied on EPROMS and a battery to keep things updated on the Prom memory.
So, unless anybody has some other input on this, that I don't know about, I'll pull a sherlock holmes, and use the deduction method.
This probably didn't occur after you first bought the tab, and the OS was fresh. Otherwise, you would have returned it.
And By the way, what is your current Android version?
I'll have to point the finger, at this time, as some sort of app you downloaded. I can't tell you which one, as I just don't know. Half a million apps on the market, and even more unofficial apps.
I would suggest a factory reset. (back up your critical stuff), and see if the issue remains.
I don't know if you're rooted, or running a custom rom. So I at this time, will say you're not.

First of all sorry for the late reply. Was very busy. Please find my comments in red.

I had this problem from day one. I didn't suspect it as a problem of the tab.
And By the way, what is your current Android version?
current version is 3.2.1
I'll have to point the finger, at this time, as some sort of app you downloaded. I can't tell you which one, as I just don't know. Half a million apps on the market, and even more unofficial apps.Since this problem was there from day one I don't think it is a app problem
I would suggest a factory reset. (back up your critical stuff), and see if the issue remains.
The only thing that I didn't try due to limited and expensive data charges in Sri Lanka. Can't spend 5-6 hours re downloading everything
I don't know if you're rooted, or running a custom rom. So I at this time, will say you're not.
It is not rooted and I'm not running a custom rom.
Since it is still under warranty I'm thinking should I send it for a replacement.
Appreciate your thouths on this matter.

Try this..
go to settings
Date and time . Look at the Set Date and take note
Toggle off the Automatic date to off .. (un check)
Set proper time and time zone . but change there formats
change the hour format
change the select date format..
Shut down your tablet.. Then restart it.. This might sound useless. But if its a error in the software that controls the clock hardware. This might trigger it to reset. We used to have this issue on the old AMI BIOS CHIPS.MOSTLY on asus main boards. of course try a couple times.. because of the date being so far off it sounds like error in what ever controls the time and date.. Not a android tech . but im guessing the boot loader controls the date.or looks at it at the least..
only other option is to root . install cwm thru acer recovery installer.. DO a backup . with cwm and titanium . that will allow you to not have to re download all of your apps.
As i said the above is likely to not work.. but i know it was a issue on some old old main boards. YOUR FACTORY INSTALL COULD HAVE A ISSUE. Just never seen this with clock....
Good luck and sorry for being so long winded.

Thanks for your post. I'm still unable to get this date corrected. Tried it around four times and still no luck.

I'm just out of guess's on this one. Never heard of it before.
But you're better off taking it back for exchange. Considering it's happened since day one, and you haven't rooted.
Don't they have free wifi in Mcdonalds over there? Or try around the tourist type areas. Cafe's and such. Usually they try and kiss the feet of the tourists.

WOWEEEEE if Moscow desire can't fix it. It must not be repairable. Giggles
I to agree send it back has to be hardware Fail.but you are welcome to blame it on me

Thanks Everyone. I will talk with the local Acer agent and see if I can get a replacement.

If your planning on getting a replacement you will have to re-download everything also, which is your reasoning for not doing a factory reset to fix the issue to start with.

I finally mustered the courage and did a factory reset. I had all my data wiped out. Took a long time to get my most used apps.
Well the thing is it did not solve the problem. Still when my tab starts I get the default date and time 1/1/2009 @ 5:30 AM.
One strange thing I noticed is that when I do a restart with my ac adaptor plugged in, the date and time are correct.
Just wanted to post so that it might help someone who's having the same problem.

Polish Rom has killed my phone !!!! :(

Hello guys, a long time ago now before the official 4.4.2 KK was available for my SM-N9005 I flashed a leaked Polish one. Before the flash my phone was working perfectly, no problems at all. After flashing the firmware I noticed my battery was draining at more than 1 percent a minute and it was pretty unhelpful to say the least, after looking at my battery info in settings says that NFC was using 63% of my battery !!! Now we all know this cannot be right ?! So I tried to disable it but couldn't as it was greyed out. It was stuck on and did not work at all. I waited quite a while and when the official KK firmware was released i flashed it but still no NFC. Now I have updated my phone to Lollipop and my NFC still does not work. Have you guys got any suggestions on how to get this working again ? It's definitely not a hardware fault as it has happened to my note and one of my family members notes after installing this firmware.
Many thanks
I have attached a screenshot that quite clearly says NFC is off although it is actually 'on' and not working. It is greyed out and cannot move it

Maybe something wrong with the nfc chip in your battery? Buy new battery (ebay) and see if that helps?
Sendt fra min SM-N915FY

Already thought of that, thanks anyway though

I've seen this happen on the S5, too. Very annoying problem, nobody seems to know if it's a software or hardware problem.
Have you tried doing a 30 seconds battery pull, and then wiping the cache in recovery? (Dalvik too, if you can.) Also clear out the cache under Settings > Storage. Let it sit for a while and see if it's off. If not, try another battery pull and see if it's off when you turn it back on. That process worked for my S5. (Which has never had any other firmware than PHN.)

[SOLVED] Wi-Fi not turning on anymore after 5.0.1 OTA. (tried many fixes, help?)

I got this GT-i9505 from somebody that says its Wi-Fi stopped working after updating to Lollipop through OTA. They claim everything worked fine before that. (I do not know what Android version it had before the update, I presume it was 4.4.2.)
Specifically, the problem is that trying to turn Wifi on makes the switch stay on for a bit, then switch back off on its own. The network list stays empty. Bluetooth, NFC, GSM and data all work fine.
I thought it'd be an easy fix. Since the warranty expired I just went ahead and flashed CM13, thinking the stock ROM was just bugged. To my surprise, that did not fix it. So I searched around and tried different fixes such as deleting some wpa_supplicant file, setting some securestorage in build.prop to false, setting "Wifi Power Save Mode" to false or even simply rooting the phone. Nothing helped, even after multiple tries. Then I tried so many bootloaders and modems that I can't even remember. None helped. I tried flashing different stock roms (4.2.2, 4.4.2, 5.0.1) in combination with different BL's and modems; Nope. Last thing I did before writing this post was to flash a stock 4.2.2 then update it to 5.0.1 through Kies. At first the phone was freezing intermitently and many things didn't work. I noticed that the CP hadn't updated - it was the same as on 4.2.2. I then quickly flashed the latest BL and modem available (XXUHOJ2) and everything is back to normal. Except for the Wi-Fi, of course...
Here's a filtered logcat I managed to grab as I try to toggle Wi-Fi on:
Code:
E/WifiHW ( 834): ##################### set firmware type 0 #####################
E/WifiHW ( 834): Cannot open "/data/.cid.info": No such file or directory
E/WifiHW ( 834): ==========[WIFI] Station firmware load ===========
E/WifiHW ( 834): return of insmod : ret = -1, No such device
E/WifiStateMachine( 834): Failed to load driver

Also, in the *#0011# menu - WiFi Information
Code:
State: DISCONNECTED
SSID: <unknown ssid>
AP MAC: null
(Everything else N/A)
MAC 10:A5:(blahblah)
(Pinging 0.0.0.0 says "Pass".)
I'm a bit of a noob when it comes to troubleshooting newer phones. I never had to deal with bootloaders, modems and so many different versions of stock ROMs before. I might have picked wrong versions.
Any sort of help, hint or question is greatly appreciated. I have also attached some screenshots that should be relevant (from the Phone Info app).

Thanks to @_Bon_Bon and @samersh72 for replying to my private messages asking about this issue. Basically they advised me to flash the latest firmware and helped figure out which are supposedly the correct ones for my phone. Unfortunately it didn't help. If anything, the Wifi switch now instantly turns off whereas it took about a second before. . . . . .
WHOA. SCRATCH THAT. DAMN. I was just typing this out as I waited for CM13 to flash/setup/boot. So it boots up, tells me I have no SIM inserted, then the list of all the Wi-Fi networks just pops up. I'm so shocked to see it as I've been struggling with the damn thing for the past two days (and nights). I'm not entirely sure I fixed it and I think I'm not even going to ever turn it off just to be sure.
I don't think anybody cares, since nobody replied and the view count is pretty low compared to the other threads, but I'll just say what else I did really quickly: After flashing the latest firmware off that one website that asks for money for faster downloads, + flashing the latest BL and NON-HLOS from _Bon_Bon 's thread, it still didn't work. So I gave up and pretty much accepted that it's hardware related. I just opened it up, identified the WiFi+BT chip and kind of pushed it in harder (really dumb and probably pointless, I know). Put everything back together aaaand.. still broken. Then I said "F it, I'll just look into getting someone to reflow the chip later or even buy a new motherboard. Until then I'll just put CM13 on it and live with mobile data and BT tethering." But thankfully the miracle happened and I really hope it lasts.

It's not that nobody cares, but it's that not many people know what to say in certain situations, so they don't say anything.
What other people could have suggested you to do, you have already tried. So there were very few other possibilities one could suggest you.
Well, good luck

@GDReaper - I completely agree. Though I think the main factor was the very specific, less "clickbait-y" title. The wall of text I wrote surely didn't help the reply count either.
Maybe a little update as I'm replying anyway. Everything still works fine, even flashed a different ROM, switched networks, SIMs etc., all is well. Love the phone.

CM13
can you please tell us how to do the thing with CM13? I have the same problem and did everything what you did and it also not worked. I think you're my last hope

Hi, I hadn't posted any more, but I later found out that it was a hardware issue (at least for me). The Wi-Fi chip wasn't seated properly on the motherboard. No amount of custom ROMs or other software could fix it. It would sometimes fix on its own if I kept the phone warm or rebooted it a few times in a row, it was very frustrating as I couldn't find a fix that would work for sure. So what I eventually did was open up the phone and put a small piece of paper tissue (that I folded like 2 or 3 times to make it thicker) in between the chip and the plastic cover. It held on for about a month or so, then it stopped working again. I went on and put a new piece of paper, slightly thicker this time and the phone has worked perfectly ever since (about 3 months already I think). Do any of this at your own risk - I already found a side effect: the SD card somehow pushed the thin plastic near it and got underneath it. It doesn't bother me but I have to disassemble the phone if I ever want to take the SD out. Who knows what else could go wrong though.
I think the correct way to fix it (if your chip is broken too) is this (and done by a professional): https://www.youtube.com/watch?v=Xs4emtglAQ8
I think the technique is called "heat gun reflow". That is, if you don't want to bother/risk with my ghetto paper tissue technique.

ok thanks for the reply. I will keep trying

Wifi driver location

Sorry, second post in a month.
A little help please from a rom specialist!
Using a cfautorooted note 3. Suddenly the wi-fi will not switch on, the icon showing light green for 1/2 second then grey - using the slider if it is held to the right, there is a light green light, but releasing the slider it returns to off. Nothing was updated/changed that I am aware of. Bluetooth works fine so do not suspect chip yet. Tried obvious - Booted to safe mode, cleared cache etc.
I have checked and compared the wifi files in /system/misc/wifi system/etc/wifi etc/wifi with those from another Note3 and they are the same (except of course wpa_supplicant.conf) - have even copied the files from one device to the other without joy,'
As Android is trying to switch on wifi but not succeeding, I need to look at drivers next. Do not want to do a factory reset yet as no guarantee of success...and need to find the fault to understand what has happened.
Does any developer on this thread know the PROCESS of turning on wifi and what drivers etc. are used and their locations.
I accept COULD be a component failure, but need to eliminate everything else first.....a repleacemnt board comes with android 5 and I prefer android 4.....and do not have a uk stock rom for this.
Sorry to re-post in different terms but this is "doing my head in"!!!! (Undertsand Linux here)

Try to reboot in safe mode to check if the incident can be resolved by software.

Wifi driver is located in "system/etc/wifi" and all files should have permission set to 0644 (octal).
But in your case, i suspect an improper disable of KNOX.

Apologies for delay. Device worked perfectly for 2 years, then suddenly stopped wifi. Noticed wpa_supplicant.conf had been set to "0" bytes long and replaced with back up copy (lost all paswords before)
and worked for one week with no issues. Then stopped again. I did see a message flash up on screen but not sure what it was but had recently had to remove updated file mamanger (ES) and also had the
SU update problem, so had to revert to earlier SU at around the same time. So something corrupted something! Copied all files from another Note 3 into three directories mentioned and permissions are
correct. I have read that early Samsug devices had problems like this with wifi and as mentioned locked on Android 4.4.2 (which I prefer). I think I will have to do a full reset, re-root and start again to see if this
cures it and never instal;l ES File Manager again.....I am sure it was to do with unistalling this! Knox has always been disabled.
