So I got a bricked Nitro HD from a friend. It was showing the dreaded QHUSB_DLOAD device, meaning it would not go into download mode either. I thought about getting a medusa box and doing the jtag restore myself, but I didn't want to invest so much money. I was trolling ebay for phones with broken screens/cases so I could replace my motherboard, but then I saw that MobileTechVideos would unbrick my device for $50 (plus one way shipping to Bryan, TX).
This was cheaper than buying a for-parts one off ebay, so I decided to do it. But it came back to me in a sorry state:
First, I plugged it into my computer USB port via a cheap type-A-to-micro adapter that worked for my LG vortex. As it started charging I saw they put cyanogenmod 9 on it. But it was freezing every other second. Also the camera didn't work, the wifi was broken, and it would only intermittently detect anything on my computer (lots of that USB detection sound followed by the USB unplug sound). I didn't yet have a SIM card, so I couldn't test the mobile connectivity.
I figured out that it was freezing every other second only when plugged into my computer. It would go from charging to discharging every time it froze. When I plugged it into a normal AC/DC converter it charged with no freezing.
Then I saw that it was a very old nightly build of CM9, so the first thing I did was download a "stable" CM10.zip for the p930. I installed it with CWM from the sdcard. This got the wifi and camera working, but everything else was the same as before.
I took the phone apart and I could see where the soldering had to be done on the circuit board--right next to the USB port. I figured one of the delicate USB signal traces got too much heat.
I got a SIM, which didn't work at all for connecting to a mobile network. The IMEI showed 0, and the baseband was for a different model. I tried to update the baseband and firmware, but that didn't do anything.
Then to my surprise the USB worked when I put it in download mode. I decided to try starting over at the unbricking guide. I put the Korean V10F KDZ on there, which fixed the mobile network connection - I could make calls. But now the WIFI didn't work among other small annoying interface issues with the Korean ROM. Also the USB now did absolutely nothing except charge the battery. No matter the mode, there was no USB communication - not even the flaky intermittent detections I saw before.
So now I'm stuck with no root, no CWM, no custom ROMs. Unless I'm mistaken, every avenue to root the device from V10F involves ADB over USB. But the USB is definitely broken for everything but download mode. Perhaps because the USB traces are good enough for lower USB synchronization speeds, or maybe the USB host for download mode uses different undamaged wire traces?
I think the best I can do now is stock ROMs with no root. I have to say I expected more from the unbricking service.
It occurred to me that it was my friend who put the retarded version of CM9 on the phone, and MobileTechVideos simply restored the booting functionality.
Problem now is that the mobile connectivity WAS working until the carrier banned the phone for having a 0 IMEI. So now I have to find out if that can be repaired without JTAG or ADB.
Hey, I got another USB cable and it works! It was just the adapter that was a piece of crap.
I restored the IMEI with QPST: http://forum.xda-developers.com/showthread.php?t=1802024
Now I can root and install custom roms!
for some reason Sony Thailand couldn't declassified, been like this since the first day. Going back and forth to service center tons of times and they COULDN'T FIX IT. My dad's Xperia Play won't connect to ANY computer, no bing-bong sound when plugging no nothing, not see anything on the phone except that it's charging, it's like the computers aren't existed, only the power gets through.
Now Sony still not fixing this problem, so for this old phone how can I unlock it and flash ROMs without a connection to PC? By any means.
Thank you!!
Have you tried changing usb cable? Maybe it is broken (mine got broken after a week or so, and it was the original one come with the phone of course), since it's impossible that they sold you a device with damaged micro-usb port.
Or maybe it is the usb port you're connecting it to: some PCs have a lower voltage in front usb ports, so you must connect the Play to the rear ones installed on the motherboard of the PC

I think they sold my dad a faulty device and when he tried to claim it after a week they didn't want to replace the phone so they told him they could't fix it. This country's Sony is known to sell faulty devices, my last Xmini was also broken...
and yes I did try other cables, Sammy, LG and some chinese made, nothing works. They did work with my Nokia N8 and S3, however. All the ports in my PC have failed, also.
so I can do nothing, stuck with RAM hungry 2.3 bloated ROM without any solution to make it faster.

by turn it off, and connect the device to the USB and press soft 'menu' key? Am I doing this correctly?
if yes then it doesn't work, nothing happens
or that I did it wrong, could you please enlighten me?

You can enter fastboot mode by keeping pressing the search button while connecting the Play to the PC.
If it's into fastboot mode, the led goes blue.

jesus chirst I was always misunderstanding the whole time my device is Xperia RAY!!! dam!

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.

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???

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.
Hi,
Last night went to check something on phone and noticed it was dead even though had been working 10 minutes earlier. I couldn't power device up and even if plugged into charger it still wouldn't charge.
I have no led showing on the phone, I've tried power/volume resetting but nothing, left to charge overnight but nothing. If I put on wireless charging it acts as though charging (no led on charging unit).
I plugged into pc and get qusb_bulk_cid:0402 followed by SN:serialnum?
Phone is 25 month old (purchased directly from Google) and has official software installed, it received an update on Saturday and had been working fine.
Any advice appreciated
Have contacted Google and they want approximately £400 to repair it
thanks

Hello,
Your phone is stuck in Qualcomm Downloader mode.
If Qualcomm drivers are installed, your device should be recognized as: "Qualcomm HS-USB QDLoader 9008" in device manager.
Why it happens and how to get out of it...
Except with proprietary Qualcomm / Google files, there is not much chances to solve your issue.
I wonder if QXDM (Qualcomm application) would allow one to get out of Download mode and reboot a device though...
Good luck,
Sébastien.

I don't have any drivers installed on my computer
I have spoken to their out of warranty repairers who say if it is a software issue there is nothing they can do as Google won't supply them with the software, they can only fix the hardware
So looking like a £900 brick just waiting for google to contact me back to see if they are going to do anything else

I'd try swapping the motherboard with a working device. Maybe one with a chatered screen or something that comes cheap...

Hi,
Well, this is pretty scary...
One of my Pixel 1 XL used to suffer of dead speaker / mic issue. My wife's Pixel 2 XL both front and rear cameras modules died. My pixel 3 XL is bug free for the moment. I do daily SMS/MMS backups though!
I'm not fan of Samsung devices, but as long as you're happy with it. That's what matters!

I've got the Samsung Galaxy Watch Active 2 after my Huawei Watch 2 stopped charging properly (and got sick of waiting for Google to release a watch) and have a Samsung Tab S6 after switching from the Pixel C Tablet (no updates and became sluggish even after refreshing it). I still have my Pixel Slate which is still working.
I had issues with the Nexus 4 which had to be replaced under warranty, but had no issues with the Nexus 6 or Pixel XL. The only issue with the 3XL was that it died after the December update, up till then there was no issue with it.
As I had the other Samsung devices I know what the UI is like and it never bothered me as never detracted from what I was doing.
But the purchase of the S20FE 5G 256GB was a no brainer in my view as it worked out same price as the Pixel 5 with my £100 cashback, and it arrived next day unlike ordering from Google where you can never get it next day.
