I need help my galaxy nexus is not turning on. At first it would start charging when connected to a charger and i was able to turn on my phone(although it would not go past the google screen) but as soon as i disconnected my charger the phone would turn off(even though battery was nearly full).I performed all the wipes but it was of no help.My phone then stopped even charging.Now I cant even get it into recovery mode.
I would apreciate any and all help you can offer
Have you already tried swapping the battery ? Because I once was in a similar situation and changing the battery worked for me.

the battery is fine i have tried another battery but it didnt work
Not so long ago i tried to be the boss and took another guy's i9000 to install CM10 for him, i nailed it, it installed and it was working perfectly fine, then after several reboots the phone got stuck in a bootloop, then it got stuck in recovery, then it got stuck on the samsung logo, and then it just died.(stopped charging) like having literally a brick in your hand, no response.
If you've done alot of mods to the phone I'm guessing something inside died, get your phone to warranty and say you cant turn it on, they'll just change the motherboard and give you the phone back, if you had any custom roms they will never know.
my phone has no warranty that i could claim so my only option is to somehow fix my gnex

Well as i said, you have probably damaged physically some component on the motherboard, it needs to be changed so you can't fix it, find a Service that fixes android devices and tell em it doesn't boot nor makes a reaction at all, they'll prolly say they will change the motherboard if they have one and thats it.
*Edit*
I remember there was a thing called "jtag" that was able to debrick devices broken in such ways. But Rarely do services have them.
Try fastboot, download mode or omap

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.

Ok so I recently just fixed my USB port because my phone wouldn't charge . I just turned it on and it finally charges but I have a problem it is getting no signal. Do you guys think I did something wrong or is it because I'm rooted but before I replaced it , it was working prefecture fine. Also I am expecting a replacement phone this Monday for this phone since I asked for one do you think they will notice I replaced the USB port?

If the usb port looks like the stock one and is not noticeable, I'd say they wouldn't notice it. If the job looks like it was replaced, has scratches and outwardly noticeable differences from the stock port, they would notice it.....
Pics may help.
You're returning the device so be sure to return it to stock and check all settings to be sure it is stock, or the usb port will be the least of your potential problems

Thanks for the reply but what do you think I should do about the no signal problem just send it like that or try and fix it? Also the usb port doesnt look like it was replaced so i think im fine.

What are the reasons you're returning the device?
If signal issues are one of them, fine.
If not, it doesn't matter as long as your device is bone stock, including all settings.
They won't be checking for signal, and if they did, it wouldn't matter as they are going to refurb the unit and you're not the cause for the signal loss, and if you were, how can anyone prove it?
At this point the signal loss can be caused by a myriad of issues, of which none may be user related.
Just make sure those water indicator stickers are dry
When you go back to stock, you may find you have signal.
The signal loss may be due to T-Mobile tower issues, setting issues, etc.
Don't Worry, Be Happy, as they say
But do be Sure that your device is Stock, including Recovery and All related settings, Including the Bootloader count and not showing Custom, etc.
I bought my S3 At&t in india unlocked here are the problems i'm facing -
1. Main problem is I'm loosing signal frequently even my 2000Rs/30$ nokia gets full signal.
2. It connects to PC like in 1 in 1000 attempts,Sometimes it connects to pc as if it is connected to charger(no storage)
Help regarding these problems are greatly appreciated.Thank you !
What ROM is on your phone?
Do you have a defective USB port that is causing the problem with connection to your PC via USB?

Using S3rx rom.
On UCUFNJ1 bootloader and modem (confirmed with T.emulator)
Are you using a stock kernel? Maybe flash back to a stock ROM to see if the phone becomes more stable.

Nope flashed stock kernel still loses signal
Not sure why this is happening. If it's not due to software, could be a hardware issue.
When did the problems start? As soon as you got the phone?

not interested bro because price already went down here (india),so I'm in hurry to sell this .....
Today it started to not charge and I'm getting it repaired because of damaged port and AC. (4.5$)
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?

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.
