[Q] HTC Repair Centre

So I sent my desire off as the rebooting is uncontrollable now (really didnt want to be without a phone so kept putting off sending it in for repair) and although extremely quick, the repair they have done is replace the antenna???
Anyone sent their phone off due to the reboot and thats the repair they done? I havent got the phone back yet its coming tomorrow hopefully but how is this going to fix the rebooting problem? I thought they had to change motherboard AND antenna?
Anyone had a similar experience? Did they put that as the repair and actually change the motherboard aswell? Did it resolve your issue?
Any help appreciated, dont fancy sitting without a phone AGAIN!!
Thanks

normally when i sent my phone to HTC they always just replaced the mobo.. would've thought they would do the same, but I guess they know better

yeah I thought they just did that too, I'm hoping they have changed it and its a mistake saying replaced antenna, dont fancy being without a phone again!!!

[Q] The WiFi issues.

Hi all, I have had the WiFi issue since day one, and can not be bothered to send my phone for repair, I probably should but that means being without the beats for a couple of weeks, which is not good at all as it is vital for work and home life for me.
I have a question, I know I have the WiFi issue, but my question is this, will it deteriate over time? and become much worse. And if so can it deteriate to the point where the WiFi will not function at all?
I ask this because I am now ready to root my HOX, but I know rooting it loses warranty, and therefor I loose the chance of it being repaired altogether, but if it doesn't get worse or break over time, then Ima root.
What would your suggestion be? Send it for repair and then root, root it anyway or any other suggestions?
Thanks !

I would get it repaired first. Personally I only found out that I had the WiFi problem after I unlocked my boot loader and voided my warranty and it can be a pain in the arse sometimes when you lose signal. So far I haven't experienced any deterioration of WiFi signals, always has been bad.

Thanks for your reply, I may sent it off soon then, its just being without it.

Are you telling me that it does get worse over time, and therefore may break completely ?

Could you explain your WiFi issue in more detail? You only said WiFi issue.. >.<

The well known WiFi issue that most HOX's have, where you lose signal when your hand is over the antenna (only sometimes its not too extreme in my case) and I've never done the squeeze test properly, but my signal is always fine, it just drops connection if I hold it in the wrong place.
Surely you know the WiFi issue (dont mean to be nasty)

My HOX came back from screen repair with the wifi fault which it didn't have before. Don't want to send it away again so I'm going to try the tinfoil fix in the next few days, seems easy enough.

Mind dropping me a PM when you've done it and let me know how you get on?
And thats exactly why I don't want to send mine, I've seen it before and its happened first hand. You send it for one fault, they fix that but send it back with another.
Sorry to hear that mate :/

[Q] Note 2 won't Turn On WiFi or Bluetooth Settings

I tried toggling it on after the 4.1.2 update, but it won't let me the upgrade was done through OTA and carrier is Fido. Same thing with Bluetooth. It just toggles back to off on it's own.
Any help or suggestions? I'm thinking of restoring it to factory. I'm enquiring for my mom's boyfriend. He does have SuperSU installed but I don't think it's rooted because I'm pretty sure he won't know how to do that. Could this be causing the program?
He's thinking about going back to the iPhone which in my opinion would be a huge mistake after witnessing the note 2 for power myself haha.
Just tried doing a Factory Reset to no avail. Still toggling from on (for a brief second) back to off.

Yeah that was going to be my next step, but then downloading the Firmware is going to take forever. I am thinking about flashing a Custom ROM so it will remove the bloatware with it. I'll update the thread when I get a chance.
EDIT: I was so smart yesterday that I flashed Stock Restore by accident and now I have to use someone's computer to flash CWM back into it or Unroot the phone...It was such a dumb mistake.........

Very well known to me issue...
1. Never attempt to undervolt Note 2, especially on low clocks. Don't play with RedPill kernel. Use stock, Adam or Perseus.
2. Flash stock 4.1.2
3. Shutdown, remove SIM, battery and SD card.
4. Press and hold the Power button for 30+ seconds (I used a full minute).
5. Insert the battery only, power on and try to enable BT and WiFi.
6. If succeeded - shutdown, insert SIM & SD, reassembly and power on. Verify again.
If not... you may try again or go to servicemen.
7. Later you can flash a custom ROM but beware of kernels and especially undervolt.
P.S. My old trusty Motorola Atrix doesn't like undervolt too. It looses BT...

Thanks man. It is super weird though because I don't think he had it rooted and I checked the Kernel that he had installed it showed it was the stock kernel. I will keep that in mine. I was also wondering and this maybe a newbie question. But n7100 can only flash stock n7100 4.1.2? I just find downloading the firmware will take forever.
Thanks for all your help guys. Will jeep you both updated.

Same Problem with WIfi and Bluetooth
I experienced the Same issue sometimes when i removed my battery i can turn on my WiFi and Bluetooth but after a couple of days the Wifi and Bluetooth can't turn on again. Anyone already fixed this issue?

The back cover serves as the Wifi antenna. When you open the back lid, the two gold prongs on the upper right are the connections to the back cover (antenna). Make sure the contacts are clean and the back lid is attached completely. When insufficient contact is established, wifi will not turn on.

This is NFS antenna. Seems having nothing to do with GHz range internal antennas.
Anyway will do no harm to have it properly attached.

Won't fix it as I've used both Jedi Master and Jedi X ROMs before reverting to rooted stock (which I'm still using) and the issue persists.I think this is a hardware issue.

Same problem over here
My problem has been on going since I bought thee damn thing
I bought it from someone for $500 back in April. The guy I bought it from must have been some sort of genius or something because every freaking repair place and computer places, in Tulsa, OK, have absolutely no idea what the guy that I bought it from did! I remember it had a custom ROM I think it was Jedix..sorry I am a noob and a girl at that :/
I have spent countless hours reading forum after forum to no avail.
So the guy that I bought it from asked me if I wanted regular 3g/4g speeds and wifi or fast internet speeds everywhere and no wifi. I, assuming that I could easily just turn wifi back on with the flip on the button, told him that I wanted fast internet and no wifi. I get home and try to flip wifi back on and nothing! Also no bluetooth. I was in contact with the guy that I bought it from and he did try to walk me through turning the wifi/bluetooth back on. He said it was simple..He had me wipe the cache, wipe the kernel, something to do with qual comm settings..blah blah I do not remember because it was months ago and so many things have been done to it since then. I shortly lost contact with him. If I am within 2 feet away from my router I can pick up great wifi but 3 feet away or further I am s.o.l. I can pick up a real weak connection in public places like my college or a hospital. I have paid every phone repair place and computer store here in Tulsa to try to fix it. They all do the same thing, just restore it with the exception of the last place that I took it to..they tried to but an older version on it thinking wifi/bluetooth had something to do with version it was on.
Please do not tell me that this is a hardware issue!- I have read countless forums and have read that I am not alone with this issue. It does however not look promising because I have never read of anyone fixing this issue. I have read things about it being the radio etc etc. I firmly believe that this is a software/programming issue however the people that I have seen this happen to never got it fixed..they eventually just gave up and bought new motherboards or new phones entirely. With that being said a motherboard could be a possibility..any ideas on how much a new motherboard cost? Sorry for being sooo long I am just so frustrated. This is such a beautiful phone and I have never gotten to fully take advantage of all of its capabilities because of this.

WIFI Bluetooth fix
Hello, I´ve also tried everything software related to no avail. So I finally disassembled the device as shown in videos found on youtube or elsewhere.
Google it!!
Reconnected the wifi chip. Turned the the device on and....wifi and bluetooth worked strongly!!! That fixed it for me!!
To be clear: I just took the screws and the plastic piece that covers the motherboard (Bee careful and patient and use the right tools!!). Then disconnected and reconnected the connector of the wifi chip, which is located right next to the lower volume button, on the board. It´s the only cable showing.
I´ve seen this problem on laptops, because of overheatin issues related to bad mainboard design, but I cannot be sure in this case without further testing.
I´ll see how long this fix lasts and I´ll keep posting.

It worked for a day and now it´s back to the same....To my understanding this is a hardware problem with the wifi/bluetooh chip.. I´m looking for the brand and model of the chip to see if I find it on Amazon so I can replace it.

[Q] Service Bars

Yesterday I replaced ad USB board (as an old one become faulty and I have had problems with charging the phone). I can confirm I used the appropriate board model.
Today I noticed that my service bars are not as good as they used to be. Generally in the room I usually used to talk and have weak 1 bar service, right now I have no service. I tested my phone outside as well and have a feeling like the phone has no as good perception as it used to have. Another words the service bars wen down everywhere about 20% or so. Phone works fine and I see no other problems. I wonder is there might be something that affects the service bars hardware-wise ? Any ideas appreciated.

The antenna. I think we have 2, one for GSM and one for LTE.
Google for a picture with exact location and try to re-tighten them.
That's all I can think of.

Thanks for suggestions. Yes the one for GPS works fine as I have no problem with GPS (that is the one on a foil. The one for connecting to the tower is a straight wire. This wire goes from the little board (with USB port I've replaced) to the MB. I reopened the phone today and removed the antenna cable. Tested for continuity - OK, cleaned the connectors but still not luck.
I wonder if this could be some compatybility issue or deffective USB board. The board shows T889 rev1.0 so it sound like it's one of the first ones. Unfortunately I made a big mistake (to late) and thrown away old board. It had a problem with the USB post but there was no problem with the signal strength. I wonder if it is common for the usb board to go bad or if there is anything else I could possibly check. I ordered new antenna cable and thinking about getting another USB board, but if this will not fix the problem I'm clueless. I also restored the phone to factory settings to make sure it is not software problem. I need to use this phone daily at work and I'm really pissed off with the problems. PLEASE HELP
Thank you - ARTHUR

Just a question, ,, have you tried flashing the modem? Not sure it would help but maybe rewriting the radio files will help you.
Good luck

GPS - Problem

Hello guys, I have a really big problem from a while. Actually im not shure from when, but I noticed hat when I tired to use Note as navigation. Problem is that then phone find satelites, lock GPS signal for a while and then starting to loosing signal, resarching locking witch interwals around 5 second and finally shut down for a while.... so for job as navigation is not a best option. I was trying to find any kind of hardware bug. I cleane all antena, motherboard, replace even whole parts including putting different motherboard for testing - yeah I know I should make a copy, but changing board was looking a quicker option.
So I get to point when I know it isnt be a hardware problem... so where I should look for a solution?

Hi, this is due to the Broadcom BCM4752 chip used by Samsung and it occurred after 6 april 2019 GPS rollover. Samsung could fix this with fixed firmware, but Samsung didn't, and I guess Samsung won't. Most of the Note 2 series use this chip, and if there is no firmware update, there is no chance but to continue using it with a GPS signal losing problem.
We have discussed this issue in detail before, please read what is written in the thread below, it will help you. :good:

Thanks for such a quick reply, yeah I read it however I was hopping this is not the case... well still my two other devices work without problem, if such kind of problems appear I just reboot them and this resolvr problem. One of those devices work on Jelly Bean android... im wondering if this could be a solution? Anyone check that allready maybe?
