[Q] Bricked my phone!

So no download mode.Did you tried vol up+ho
me+power to access the recovery?

Your options are:-

1) A jig.

2) Possible JTAG; this is the cheapest/most stress-free option after #1 (which will cost a few bucks on little e big B), but....Don't get your hopes up it will work, many phones in this situation are not JTAG'able. If you can find someone who will attempt a JTAG for you & you only pay if it's successful, knock yourself out. I wouldn't be paying on the basis of it costing me money upfront whether it works or not though given the next (and overwhelmingly most likely option).

3) Motherboard replacement - irrespective of warranty status, a Samsung service centre should replace the board for you with a new one. This will be somewhat expensive. How expensive will normally be dependent on what phone techs charge for labour in your country.

You also have the option of sourcing a 2nd hand board (cheaper) online; I believe KeithRoss39's 'Replace USB board thread' in General has a list of online S2 parts suppliers to get you started, a Google search will yield others, and then taking the phone & board you've sourced to a local mobile repair shop (non-Samsung service centre) & paying them to swap the boards for you (assuming you don't have the necessary skills to do this yourself). This will be significantly cheaper than the new board option in most cases.

So, in summary, the enormously more likely fix (that will actually work) is #3, with #'s1 & #2 a lot less likely to succeed, though definitely still try #1 unless you're not fussed about spending the money to do #3 right away, and possibly try #2 with the caveat I mentioned.

Edit - Also/before you ask 'what happened/why did it crap itself', nobody here can give you any indication of that. There's obviously something major hardware-wise going on, and without the phone open in front of us, it's impossible to give you a meaningful answer to that question. And though it's a natural question to ask in this circumstance, it's kinda irrelevant - the phone has a hardware fault of some kind, it needs to be diagnosed by someone qualified & fixed. That's the best we can give you.

Extra edit - Actually, as well as trying to get into both 'modes' over and over and over as TheImpossibleEnemy excellently suggested, find Hopper8's 'Odin troubleshooting' thread stickied in General, and try the 'jump start' method where you try to boot the phone with just the charger/minus the battery detailed in his thread. Like #1 & #2, very unlikely to work, but given the alternative/money involved with that, you absolutely try it.

Unfortunately, unless you are able to get the phone to boot, you won't be recovering anything from it. Motherboard replacement means you get a new EMMC, and the only (very) remote possibility of extracting data from that without having the phone work somewhat normally, is a data recovery company which specialises in pulling data from dead HDD's. Fairly unlikely this is possible though (I've never seen anyone post they've been able to get this done in the 2.5 yrs I've been here), and if it is possible, expect it to be very expensive relative to the other fixes.

There's a thread in General which has people offering to share their jigs, take a look - there might be someone near you with one, which will might save you at least a couple days/a week/whatever waiting for a little e big B delivery.

Good luck.

switch the screens and that's it!:good:

The only problem with that one is it's most likely something on the MB has crapped itself; given the size of the components concerned, no tech worth their salt would attempt a fiddly replacement of individual components on the board given most electronics is 'modular' (everything is made up of 'boards') these days, and it takes no time/no stress for someone who knows what they're doing to simply swap a board.

Having said that, over the last 6-12 mths, we've seen threads/posts by people claiming they've been offered a fix where just the 'power IC' is replaced on the board. I've not seen a single person post & say they've had that repair done successfully in that time though, and you can easily end up with the situation where it's something else on the board that's buggered/as well, so you end up needing the board replaced anyway, or someone attempting the repair stuffs the board up because their soldering skills aren't up to scratch.

If the easy stuff you can try yourself doesn't work & you definitely want to keep the phone, replacing the board in the first instance is the (almost; assuming nothing else is wrong) guaranteed fix.

Edit - But yeah, you can definitely have a stab at trying the good screen on the dead phone on the good phone with the dead screen as per TheImpossibleEnemy's great suggestion. Doesn't get you your data, but it might just get you a working phone for pretty much nothing. Search for the service manuals on here (they've been posted from time to time here) or Google; these have full parts lists & diagrams/pics with run-throughs of the most common repairs (replacing screen is one of those from memory).

Replacing the screen would be easier.

Never had to
Just my opinion,because to access the mobo one would have to remove the screen first.
The choice is yours of course,as you are some kind of engineer,it should be easy for you to do it in both ways.

I have some experience with taking the S2 apart.
The way to take apart the phone is to take the back off of it......
This will reveal the circuitry on top of the screen and the circuitry fitted to the rear housing. You will be able to access the motherboard before you access the screen. Adding the *good* motherboard to the *good* screen will be the easiest option for you......

You'll find a link to a video that shows a step by step procedure for stripping an S2. You'll also find links for part suppliers......
