I'm in the EXACT same condition. <click here>
The device is hard bricked and no software, JTAG, JIG, etc. can repair it. I went to two samsung service centers near my place and was told that the motherboard needs replacement (costs around $250) so I decided to use it as a paperweight and just ordered a 32gb Nexus5 instead.
You might want to try this: <click here> but you need a linux system, good eyes for soldering something that small, and proper tools (~20W-30W soldering iron, flux, very small wire), and of course, the unbrickable mod software. Good luck! :good:
thank you ej8989, I will definitely try the mod, I didn't really want to leave my nexus s now..
I was planning the get a moto x next winter, at much lower price than current one

Charging pin not working! How to replace?

Hi guys,
my phone's charging pin is not working. I am unable to connect any charger properly. It is happening with 3 chargers and a usb cable. So, I need to replace the pin. But, I have no idea where to get it done. Suggestions please?
Also, is it possible that I can fix this problem by myself (maybe it is just dirt issue)? If yes, how do I proceed with that?
Okay, so I bought new charger, got the pin changed, and still the same problem. My phone doesn't charge while it still displays "Charging". It doesn't matter whether it is connected or not. It just says "Charging". I have done two clean flash, and same issue. Heck it happens even with DDLF2. So, I am out of ideas.
Someone help me here. My phone is a brick for past 2 days now.

those idiots are charging around 7,000 rs to change motherboard at service center !!!!
holy hell. that is pretty much useless then.
If i were in your situation i would search Ebay for that part (Charging board).
And if possible with the tools including everything you need to disassemble the device.
If you're not experienced with phone repairs... Dont worry.
Check this i9003 Disassemble Video: http://www.youtube.com/watch?v=9UW4T-aNkQY
The video shows that there is a Charging part.
Search for that part or dead / damaged devices.
Replace it and you're done.
If you want to go the hard way...
There are charging ports for 1$ or 2$.
If you have the proper tools its easy.
If not there are other ways. But it's very risky.

Thanks for the help. I did asked mobile repair shop here, and they are expecting 100rs.(less than 2$) to replace the part. Turns out it is pretty common part and is almost always of same specifications.
Okay, so the socket/pin was not the issue. There was some water damage to the assembly itself. We tried 3 different sockets, and all resulted in same issue. But, replacing assembly itself was cheap enough. So, finally my phone is back and charging fine. :victory:
Good good and good again. Another SL didn't bite the dust.

[Q] Vibrations not working - back cover won't stick

Hey guys,
last night I decided to replace the back cover of my Xperia Z3. I've ordered an original one and got to work. First problem is that it won't stick - the adhesive sucks. Shall I heat it up with a hair dryer or something? I don't want to damage anything inside the phone itself. And here we go to the second problem - after installing the new back cover the vibrations stopped working. I've performed a full wipe, reinstalled another ROM (wiped System, Data, Dalvik and so on) but it still won't work. Since it's a hardware problem, which part shall I check and then replace? The buzzer itself or maybe some connections?
Thanks in advance
Anyone?

Z3 shares same flex cable for the power,volume buttons, lcd and vibration so u need to check the flex cable.
I recently replaced mine due to stupid service center people refused to entertain my warranty.
If you not so sure, u can take help from professionals.
And you can get the adhesive online somewhere if you damaged the supplied adhesive with the back panel.
Also be very careful while putting that adeshive first put on the panel and stick the panel to phone back.
Gud luck..

Thanks, I just ordered the flex cable yesterday after some reading and I will be replacing it today or tomorrow. My warranty was refused due to me replacing the back panel on my own :good: Thumbs up for all the warranty services. Soon we won't be able to change wallpapers without getting our warranty void.

It was brand new and everything else works.
EDIT: now the upper part of the screen won't work... Today is just one of those days... I changed the flex cables back and forth - same issue. No vibrations and no upper screen reaction. FML.

Can u check with old flex if the screen is functioning if yes then your new cable must be faulty.
I had no such issues, and since you yourself opened the device it should not have any issue with motherboard

I switched between flex cables and the problems persists. I've been sitting and trying to fix this with various ROMs, cables, buzzers and other things for 8 hours now. I'm gonna reassemble the phone as carefully as possible, flash stock ROM and send it to Sony again. Maybe this time I'll get lucky and they won't see that it's been opened... I don't feel like spending 300$ on fixing it on my own.

Were you ever able to fix this? I had the same exact problem as you, replaced the LCD/digitizer on my Z3 (D6603) and then re-installed everything and now my vibrate motor doesn't work. I bought a new flex cable/with vibrator motor, installed the new one, but the same problem occurs. Vibrate doesn't work at all.

Unfortunately, along with the vibrations, also my screen stopped working. I gave it to the warranty service, where they told me it's my fault, cause the damage is mechanical (how? I have no clue, cause there was not a single scratch on the phone) and they proposed a repair that would cost 110% of the phone's market value. I simply sold it for parts on eBay and bought an SGS6 Edge. No more Sony for me - their support sucks ape balls.

I can confirm the fuse fixed my buzzer.
My fuse had blown open somehow so I replaced it from a donor board and now it vibrates as it should.
Oh it's just above the clip that holds the board in place to the left of the large cable j-tag connector for the on/off vol camera and buzzer/vibratorView attachment 4720024
Yes that's the Z3 dual but is the same for the D6603
And he sold his phone by parts at last
Lol ?.. ......
I enjoyed this a lot

Question Who knows how to short the test points to enter the Qualcomm EDL flash mode

My Edge s bricked several days ago, Technical support said that there is no way to flah it back, except replace the motherboard, but the fees are high enought that you can buy a new one, so i give up, Today I disassembled the phone and tried to find the short test points to enter the EDL mode, But I don’t know which are the test points,Can anyone help look at the attached pictures, thank you.
Friendly reminder, Please don't try to relock phone like I did.
Unfortunately, I do not know what points to short in order for this to work, however I had a similar issue with my Asus Zenfone 6 and was able to resolve it using the following cable...

Just to be clear, did you try using the stock, factory firmware files and:
Code:
fastboot flash partition gpt.bin
fastboot flash motoboot bootloader.img
fastboot reboot-bootloader
I soft-bricked and did those three commands, then was able to flash back to stock via LMSA.
wow, I have the exact problem now for Edge S/G100 .... searching for "test point" brings me here.
I'll try the above FB commands and am still open for suggestions. Thanks...

I find that hard to believe; manufacturers love test points. They don't trash mobos over firmware... there's a way.
They aren't mark if present.
The location is likely proprietary until someone figures or leaks them out.
This is all I could find. Try asking here perhaps.

Nope, on more expensive devices, the boards between EVT, DVT, PVT revisions change a lot because they can afford to. Production boards for this phone simply don't have the pins for it.

Yes, well... the pin outs for that chipset are available from Qualcomm.
If there is no pin for that function on the chipset, then there's the definite answer that there's no way to do it. That's an easy way to verify it.
Otherwise it's game on...
The way to find it be to hot air the Qualcomm chipset off a trash mobo and trace out the correct pcb contact from the base of the BGA chipset (I assume it's a BGA form factor). The trace goes somewhere. While it could be s completely internal trace, I highly doubt that's the case. Even then there are still ways to get to it.
If the pin is there, there's a way...
Just depends how determined you are and you're skill level. Prototypes and repairs sometimes end up as scrap so you need to accept that reality as well. If you have a blown mobo to experiment and practice with you have nothing to lose.

about your advice do mean locking the bootloader after you unlocked it?
plz anyone plz answer me that my oneplus 9 5g has been hardbricked by me so can i fix it using edl cable??? plz answer as soon as possible.
Thank You.
To original poster: If you get Fastboot mode running which is what it looks like you were able to do, you can recover with the Motorola recovery tool. Otherwise if it shows up only as a serial device you need blankflash which I posted previously in this forum. I have bricked and unbricked my phone many times trying to get LineageOS and other things working on it since it's a little funky as a device swapping A/B stuff a lot on it's own.
Thanks

Was there ever a solution made on this issue? I have the same problem
FFS, people, If you can get into Fastboot, your device is not bricked. There was absolutely no need to open up the phone and disassemble it. You have to go into Fastboot mode to use the Motrola Rescue and Smart Assistant Tool.

Question Any way to bring back a Hard Brick of Moto G Stylus 5G (Mediatek).

How can you blankflash if the computer is not even recognizing it?
Not too much to do if you can't boot into preloader by holding down different buttons/combos. Nobody has publicly shared schematics or test points for xt2211 afaict. Maybe you can find someone to share privately. You could also take it apart and start grounding test pads with through a resistor and maybe get lucky.
Only other thing I can think of is pulling the emmc and mapping out traces. If you were to find a trace that exposes an important signal like emmc_clk, you could ground it, and the processor should boot directly to brom afaik. Very likely to be destructive without equipment to reball though.

I've since rolled over the phone with the car. There is no BROM mode for modern Moto's - Lenovo has confirmed this for phones made after Jan.1 2022.
So if you brick it, its good to run over with a truck.
