Hi All,
I searched and read a dozen post for this and have yet to find a solution. I made repairs to this Note 2, replaced the USB/charger board. The phone had been wet. This fixed the first problem, but now I have a new one.
I installed CWM recovery and installed a stock rom in order to obtain root and,,,,,,,,,you get the idea. I have flashed back and forth between several roms, inc Jedi and three or four stock versions. Yesterday I had WiFi for a few hours. This morning when I got up and turned it on, I can't get it to connect to WiFi or BT. It just says "turning on" and does nothing.
The phone is unlocked and on AT&T network. It has 4.1.2 JZ054K. UVBMD1 in it. I've tried many combinations of modems, kernels and roms. I've tried to match them and tried combos. No luck.
Because I had it apart, I fear a hardware issue. I'm hoping someone will have a suggestion that will allow me to keep the "unlock" and connect to WiFi. When I flashed the custom rom, it appered I lost my "unlock". Of course I got it back when I flashed back to stock.
Any ideas would be greatly appreciated.
Got it figured out.

When I repaired the board, I had it disassembled down to having the mother board out. Evidently when I was handling the mother board, I pushed down the little contact tabs that make contact with the back body panel which make contact with the antennas. I found a video which showed me which antennas were which. Once I reassembled the phone, it worked fine.
So it turned out to be a hardware issue after all,,,,,,,,,of course I caused the issue.

I have a stock samsung tmobile s4 & I was having problem with the charging port so I took the charging port out and tried a different port & put everything back together now the phone charges but the digitizer stop responding the bottom buttons are still functioning & I am sure there is nothing with the digitizer itself I have also clean the cache factory reset everything and also used Odin to flash the stock rom again but non of these seems to solve the problem so any advice or solution will be greatly appreciated

You probably disconnected the digitizer when you took apart your device
Sent from my SGH-M919 using XDA Free mobile app
Maybe you broke your digitizer when you took it apart. ???
Pp.
No I didn't everything is connected properly I triple checked the connections I also tried another screen from my other s4 and it still doesn't work & also put the massed up one on my working s4 and the screen works perfectly so I'm thinking what could be the problem
It could be an issue with the motherboard.
Did you do any soldering?

That's my first thought. Somehow the board got damaged during the repair.
Its the only reason 2 working parts would fail in the same way when installed on your device

I didn't touch anything else other than disconnecting n connectin the digitizer & the chargin port so I'm not sure how would the motherboard get damaged
I have two pieces of ZF2 ZE551ML at home. One is my and the other one belongs to my wife. My wife's phone had a broken mini USB port - the first 2 pins from the left were visible - the plastic had broken apart. Firstly, I did not relaise it could be the problem, luckily I managed to change the whole PCB including the broken USB port, however after this change the phone is not being detected by a PC, nor it is fast charging. As I have two phones at home, I checked performance with the other unit and unfortunately, the other one does quick charge and is detected by aPC, so it is not the cable, neither is it the missing software.
I bought another PCB and changed it as well, however still no joy. Does anyone have any brilliant idea how to fix it. I should also say that all other or most of the functions of the phone are working fine (at least those I managed to check: GPS, Wi-Fi, GSM+dual SIM, torch, bluetooth, and so on).
The only problem is that the phone loops on the SMMI Test #1 and is not going any further. I have also tried to detect phone by adb, still no joy. The phone is not rooted!
I have my personal suspects that it could be the faulty main board or a software bug. Any ideas how to fix it?
My phone is running LP 5.0, soft: LRX21V.WW-ASUS_Z00A-2.20.40.198_20160930_8756_user044030427_201501060109, kernel [email protected] #1 Fri Sept 30 15:31>23 CST 2016
Sdcard slot is working?
I would check the connections on both ends of the flex cable with the sim and sd slots on it.
I am having the same problems (because of the busted sd slot). I ordered a new flex cable. When it arrives (approx. 2 weeks) I'll know if that was the cause.
Yes, SD slot is working and both SIMs, so the phone itself works fine, only very long charging and is not detected by a PC.

may be the pcb you changed is for different version. try replacing it with your other phone if you have the same model. post if works.

Hi, I did changed both PCBs between phones. Firstly, I had the same problem on both phones, then I made better connections and the batteries started to warm up. Finally, the new one works with the other phone, the old one from the other phone still creates the problem. Probably, it is not the PCB then, or USB connection. It must be something else.
Anyone, any idea?

try fashing raw firmware
on motherboard you can inspect or clean the connector where pcb connects. use magnifying glass to inspect connector
Ok, I actually would like to flash the raw firmware, however I need some guidance here, as the phone that has a problem, is not rooted, and it cannot be detected by any PC now, so I am stuck in the middle and do not know how to proceed...

i am little confused here... you changed pcb on one mobile and fast charger do not works on that. you have other mobile which is working perfectly. both are same model.... if right!! do the following thing to find out...
Phone A:- changed PCB. no fast charge, not detected by pc.
Phone B:- working perfectly normal..
now we want to guess if pcb is faulty or there is issue with flex cable or any software related issue..
remove motherboard from phone A. and install it in Phone B.. if on Phone B. things works well then definitely its problem related to pcb.. if things don't works on phone B too. then it may be a firmware related problem..
raw cannot be installed without pc..... the thing you can ty is updating firmware from sd card via recovery mode.

That is correct, I say it again - I have two phones, same model, same software, kernel, etc. One had a damaged mini USB port, so I purchased 2 PCBs which have mini USB port souldered onto them. I bought them twice, as I was not sure if the first one I got was the correct one. Now, after your first message I changed the PCBs between phones and the result is the same, phone A (which is ok) works with the replacement PCB, and the PCB from working phone still does not work with phone B (the one that has a problem).
As a second step I replaced motherboards between phones now, and the result is still the same, meaning the motherboard from phone B does not seem to work better while it is in phone A body. The symptoms I'm struggling with are: charging takes over 8-9 hours, so it is considerably extended charging (battery is original factory battery 3000 mAh), the phone does not fastcharge at all and it is not detected by any PC.
The phone is not roooted so, I'm afraid I cannot make any changes to firmware through recovery, as it needs to be connected by a cable to a PC, unless there is something else I can do about it, but how to get any further?

which firmware you are currently on? lolipop or MM? factory reset your device then apply latest lolipop update from sd card

I was on lolipop, updated to MM now, but still no joy, charges very slowly like before and when connected to any PC it says one of the recently connected devices is not working properly, so I'm stuck ... I cannot root or apply any ADB sideloads ...

Is your ext. sd being seen in file manager ?
Can you get into 6.0 recovery ?
If yes , you can now downgrade which will reset your fone , With a factory reset in the process , check my signature below.
Your fone not being seen maybe driver issue if other zens too are not being seen...but ..let's see what happens after downgrade.
After downgrade if still slow charge, reboot while connected to charger.
If same prob ..hardware !

Thanks, I was not so deeply checking all available options. SD downgrading worked well for me, however the problem still is in the phone. However, I discovered a few positive and negative signs, which tell me that there is something else - could be the connection - after upgrading to MM before the phone was restarted at least 3-4 times the screen was not going to sleep mode after a minute, it was coming back on and on and on again. After 3-4 restarts it behaved normally again. The same thing happened after downgrade to L.
Another positive discovery is that the SMMI test now works well and everything is ok now, before it got stuck on the 1st or 2nd test and was not going any further ....
One more spot, which was very hard to catch as it popped up for a 0,1 second but dissappeared then quickly so I had to record it with the other phone and play very slowly on the PC - it looks like the Asus cover window pops up and it says - move your finger around the circle to get quick access to your preferable apps and there is also a blue button: Do not show again . This is flashing now and then and I do not have Asus Cover, so the behaviour is quite odd to me.
I have a feeling that there might be something with connections, but really I do not know what else - I checked it 30 times and made sure everything was properly alligned and tight when I was changing the PCB with micro USB port.
By the way the other phone works well on PCs, so I must have all drivers installed, it is just the second phone that is half bricked... I'm wondering now if maybe flashing CM 12 or 13 will help, however as it is not rooted probably it will not work via SD card... or? Am I looking in the right direction?
Buddy , its hardware so software tweaks will be useless .
Buddy, we are on the same ****ing boat.
I tried to go back to 6.0,but i got my phone bricked and now i cant reverse it back because i need usb connection to the computer and simply it isnt recognized.
I suggest you to send the phone to the asus assistance centre or to buy a new usb port for your phone,as it is clearly damaged like mine.I need to do it too so if you want to wait me first so i can check if it works,ill maybe save you some money.

Well, my phone successfully reversed to Lolipop, and I changed the USB port, I talked to Asus authorised service centre and they said it will cost the price of the phone, so I just give up, as everything works, but not the phone with the computer via USB and not the quick charging. Asus centre said it is a motherboard failure, but I'm asking how is that possible if all other functions work well???

Yes, I see your point, but I cannot imagine how is this possible, when all other things work well on the phone and the SMMI test shows all sensors working properly?

Ask yourself the same 2 questions again once more
Is your phone recognised by PC ?
Is fast charging working now ?
If answer is no after downgrade .
You know the answer
i changed mainboard and working
well, i have the same problem and i try the following possibility and all unsuccessful.
1. i tried 3 different pcb still no luck
2. i changed sim flex still no luck
3. i changed battery still no luck
4. i changed lcd and digitizer completely still no luck
5. i wiped cache from android recovery MM still no luck
6. i wiped data and factory reset from android recovery MM still no luck
7. i install same latest os (MM) for ze551ml from sd card still no luck
8. i use original ac adapter and cable and tried working different one for every step.
so i want to ask a questions. can it be ground connection somewhere on cases? or motherboard
i am tired but problem found. it is exactly motherboard problem. i bought used original mainboard and all is working.
Note: other mainboard using same android os version so it is not os failure.
I have the s3 and the charging port on it does not work, wont charge no matter the cable, I've taken apart cleaned out nothing helps so I used another old s3 to charge batteries. I couldnt hook the phone to the computer due to the charging port so I would download roms onto a SD card and rooted using kingo and installed twrp using flashfire. I was testing out some roms and flashfired stock mk3 and nd2 which was fine but when I went back to mk3 moar 6.0 flashfire did not work with that version, so I twrp wicked mk3 rom and everything was ok. I had liked wicked x, I was having trouble flashing the nj2 firmware using mk3 so I flashed the the mk3 wicked. I also flashed the custom recovery (philz i think) that was preferred by the rom. Using the sd card i used in multiple devices, I clicked the samsung tab twrp by accident, it flashed, I didnt have a zip of the correct recovery and couldnt flash a image in whatever recovery i was in at the time.
I figured screw it I'll flash it once the phone boots up using flashfire or twrp app. Phone booted up, started initializing and turned off. I read in wicked x nj2/nd8 if you werent on that bootloader youd bootloop, I thought maybe being i had flashed nj2 bootloader before I might be ok. The phone just sits at the boot animation for wicked x and the buttons will flash like its about to boot up fully but never does. I cant get into recovery mode because I flashed the t217s twrp instead of the s3 one, I cant connect it to a pc because the ports messed up.
Is there a secret key combination or any genius ideas of making something happen with this or am I left at either replacing the usb port or trash it? I have another s3, its a verizon and the motherboard chips are a little different but was thinking of taking port off that and putting it on this s3 but not sure if superglue will be as good as soldering which i've never done. Is there a way to do anything in download mode without using a computer? Is there any tricks like putting aluminum on the tip of the charger before putting it in the phone that will connect it? lol anything? I had the workarounds great before but completely FD myself in a two hit combo I cant seem to get out of. I was doing fixing it for a friend, who also gave me a s7 that I was going to replace the screen on but the battery ripped open when I was prying it off and it puffed out smoke and if I touched it anymore it would spark a little so I threw it in a zipbag of water LOL cuz the note 7 fires so this one I need to have like the sweetest rom so I can be like oh and that s7 was like exploding and he wont be too upset plus with the note 7 issues i can suggest it was related, but with two non working things I am what I am apparently, an amateur.[/B
I couldnt figure out how to make it paragraphed, I put in tabs but it defaulted to terrible look and tried the align option but looked worse so hopefully the bold and unbold will be good enough Forget it i tried like 4 different things, i wouldnt read it either
You will have to repair the port before you can do anything else.
Do it for free - swap out the parts from your old S3.
I figured that was the only option, it sucks I couldnt believe it like i was cast down for my filthy sins lol like hazoos. It was obviously meant to happen for whatever reason, with replacing the port if I use any other mini usb that has same number of metal connectors (identical to s3) alls I need to make sure is that they are touching on the board right? like if I had to could i tape or even press down on it or glue it as long as the metal is touching the metal should be good? Glue concerns me cuz i dont think its a conductor so it could block the metal to metal, soldering concerns me since ive never before and have read that with this project if you havent soldered before it would be easy to burn up the board or anything else. Theoretically it should work if the 5 or whatever metal spots on board with a wire or metal something touchin each tab on the charging port it should work. lol messing around like this might end up having some type of walking talking frankenstein android. but i only need to do it once for like 5 min to flash twrp. I was going to swap motherboard out but the motherboard on the verizon s3 has different chips and doesnt fit into the spot on the sprint s3. Only option would be to seperate the frame from the screen. Sprint s3 has working screen/bad port, verizon has broke screen/working port. Tryn 2 do it so i can save face when i tell him his s7 had that note 7 bug but heres that s3 and customized lol. im' fd
