JTag Did'nt Bring Device Back? - Galaxy Tab 2 Q&A, Help & Troubleshooting

When I bricked my Tab as I tried to fix it I was told to take it to A repair centre or riff jtag, I took the advice by taking it to A repair centre, They said they attempted jtagging the machine and putting the orginal boot loaders on it,
They said "There's nothing else we can do" So the question is, How can A simple wrong firmware installation fry the motherboard?
I call this A Hardware or Permanent brick, I am thinking it may have destroyed the partition tables on the data chip.
Didn't know clock work was that strong.
is there anything else I can try?

please reply...

[Q] Do I now have a £300 brick?

Turning on my phone today and it was stuck on the HTC logo. After 20 mins, I pulled the battery (all I could do) now when I try and start it, it just vibrates 5-8 times and refuses to start.
Is there anyway to sort this, or should I return? The phone is only 6 weeks old, so I can get my money back on it.
If you haven't modified the phone (S-Off, root etc) then I would just take it back to the shop and ask for a replacement. After only 6 weeks they should still take responsibility for it and not make you go via the network provider for a replacement.
Yep, as long as you haven't voided the warranty (root etc)
They'll be more than happy to replace it.
Good luck with that.
The quality of these phones is really quite bad. Mine was also one with a gap at the top of the screen..
That, as well as the emmc problem means I wont be buying another Desire S, or HTC phone.
even if u voided the warranty,the emmc cip is broken and they canot know anything you done on it...
think in a positive way..when you bricked your phone accidentally,with working recovery,but you cannot do anything,you can jsut try your best to fry the emmc chips by keep on pulling battery,so that it'll be covered under warranty

Great, never knew that

N5 repair in shop

I left my Nexus 5 in for repair a week ago to a local phone shop, it had the faulty power button problem which was causing a bootloop.
Fast forward, they tried replacing the button with another but said the new button did not work,
They now say that its likely the motherboard and have ordered one for the phone ?
Does this sound like a genuine explanation or have they possibly damaged the motherboard by a botched job at soldering ?
Cheers
I would suggest getting it back and doing a visual inspection because a new motherboard is expensive.
9 days later , I Phone the repair shop today and they said my phone cannot be fixed , worse still they don't have it but its "on the way" from a courier someplace.
Very poor service that they took it in the first place saying "no problem , we can fix that in a few hours"
The phone was still working when i left it in but now im afraid when it comes that it will be totally unusable , my suspicion is that they may have messed up the soldering.
The guy has apologized over the phone but said i need a new phone and offered me another phone (they dont carry nexus) at a discount. but I'm still fuming.
Not sure what to do.
Not sure if they did screw it up or whether there is a problem in addition to the power button.
You may as well wait until you get the phone back Definitely check the imei if possible to make sure the company returns the correct phone. Examine it closely for any other potential damage/changes from the original.

Thanks for that, any particular things i should look for ? Im thinking of taking it into another place for a second opinion, the phone was working intermittently before i left it in , meaning i was getting a few days of good use than maybe an hour or 2 of constant rebooting that was definitely the power button .
Also do you think i should ask for any compensation from the company ? its hard to know.
I would definitely look for stray solder, damaged ribbon cables, damaged motherboard connectors, and broken clips. If the repair shop did something to brick it, there may be no signs of physical damage.
Rather than send it out again, you could look for a used N5 with a smashed screen and working motherboard. This way, you could just swap out the motherboards and you'll have a few spare internal parts.

Thanks again, I had a look online at the teardown video and it seems fairly straightforward to swap out parts (i previously had changed the battery myself) .
I just don't understand why they could not fix it, especially when he said they will put a new motherboard in it. surely that would have sorted it . just dosent make sense, perhaps they just cant be bothered ordering a new part.
A new motherboard? That should completely solve any problems since nothing on the motherboard can be replaced by a cell shop, even lg, unless the shop damaged something on the lcd.
Yes he mentioned changing the motherboard for a new one, you dont think even the power button can be replaced on it ?
Sorry about my confusing post.
Yes, the button can be replaced, but that is about it. There are only three solder points for the power button I believe. The wifi chip, emmc, and sim reader cannot be replaced.
Hopefully, it will not cost too much for the replacement motherboard.

[Q] About bricked phone and warranty

Hello. Recently I bricked my phone to point that it only show a black screen, and the notification light when connected to a power source; I got there by flashing a ROM that was intended for another regional model of the phone (I didn't know at the time).
Now, I know that this questions are morally wrong, but I want to know the answer prior to hand the phone to the technical service provided by the warranty:
Can they know that I flashed a different ROM even if the phone is in a "hard-bricked" state? This is important to me because the warranty covers the fix if they can´t prove that it was an user fault.
The other questions is, are there any non-user faults that could get a phone bricked, similar to a bad flash?
Thanks.
Any help please?

Static screen...

My phone lookslike this....
Checked flex cable,no luck....anything else?
No cracks or damages on the phone screen, took battery out. Still noluck

Need help, got no warranty and the guys at the service said "replace the display or motherboard" they didn.t even opened the phone, I know I can fix it somehow.....but how?

is bricking a myth?

Is bricking a phone just a myth? I mean there is always a way to fix it isn't there? The phones are a blank slate when they are produced so I would imagine you just re-flash the stock OS with Odin don't you? Brick must just be a word some n00b associated with his phone when he couldn't fix it comparing it to a coaster cd, would this assertion be correct?
i understand a phone would become hard-bricked if you destroyed the hardware in some way but could someone cause an unfixable soft-brick?
Bricking a phone, as you realized, can mean both "it got soft-bricked" and "it got hard-bricked". This forum at 99% is used by people who think they have to redesign a phone software-wise and when doing so miserably fail - will say they soft-bricked the phone.
Have always wondered why people buy a phone of which they are not convinced what does not have the features they expect.
A soft-bricked phone always can get fixed, at least by authorized repair center. That's also true with hard-bricked phones.
Unfortunately, bricking is real and not only a myth. Most of the time you can easily repair a brick, but there are also hard-bricks that can’t be repaired or can only be repaired with soldering knowledge.
As jwoegerbauer has already mentioned, you can try to contact a repair center, but if there is no official repair center nearby, or even worse, there isn’t an official repair center at all, your phone will be a useless brick :/

If i'm not wrong, flashing corrupted bootloader and prebootloader is unfixable without soldering knowledge because it destroys the bridge between flashing software and the phone??
Flashing a corrupted bootloader and prebootloader will cause a hard brick. If I remember correctly, you can sometimes still fix the phone without soldering, via EDL mode, but that still requires a lot of knowledge and time. Either way it would be a really bad situation Please correct me if I am wrong.
