How to know if the MoBo is bricked - Galaxy S II Q&A, Help & Troubleshooting

Hi!
Sorry for asking again - i had another thread about this subject before thinking this solution to my problem, I think the situation and the question is different, so that0s why I thought, opening a new thread was correct
What happened is that I was enjoying my SGSII with CM 10 and one day it just shut down
I only could enter download mode: When flashing with Odin, Odin would hung and the flashing process never would start.
Finally I tried to flash official 4.0.4 with the repartition option checked.
No download mode no more either....
Needless to say, I got a brick.
Now: Samsung refuses to repair it with the warranty and some online shop says they can repair just the memory module and not all the motherboard: I don't know if the motherboard was broken either.....
The thing is that I wish I knew if the MoBo was the problem before sending the device over to the online shop and getting it back not repaired again... having to pay for the delivery... perhaps for samsung it's easier to just replace all the inside instead of only one compound.... I don't know that....
How can I know if the problem is not the whole motherboard?
Thanks

I had the same problem not caused by cm but just trying to ged rid of jellybean, no boot, no download, no recovery and not charging anymore
i tought i was screwed by odin because this caused the problem ( also ticked repartition ) brought it to a shop that actually repairs damaged screens and after a couple of days got my phone back with still everything on there wat was on my phone before i bricked it.
Had to pay € 45,- so to me next to nothing compared to bying a new phone.

Well, that's a relieve... I mean, if the Motherboard were broken, I wouldn't even get to download mode... it clearly looked like the fash memory failed.... I hope this guys are right and I can get my phone back..
I need to say Samsungś service sucks!!!! Despite of not being covered by warranty, they had my phone, and i quote "LOST" for almost two months....
I'll update as I get the phone repaired....

Thats why it diddent even cross my mind tpo bring it to a samsung service center, it probally takes a lot longer to get the job done and they would for sure replace the mobo and then say it was broken because i flashed it with a custom firmware, like that wil break the device, morons
So to make sure it was done fast and the proper way i took it to flexiphone and sved my selfe the trouble of getting a lot of bull**** an probally a
high amount of money to pay (because of a warranty void) for a repair that never needed to be done in the first place.
Hope your device has the same problem cause i was depressed missing my righthand, but went home with a smile from ear to ear.

OK, got the phone back, took it to a shop and they say it's not responding to JTAG.....
They will try something else, but it does not look well....

if it's not jtagable then mobo replacement is your only chance to see the little guy booting again.

Ok, I've got a bricked MoBo....
How much would it be to get a new one? I guess it won't be less than 200 euro.... or perhaps new phone directly...
I guess It's goodbye..... farewell, SGSII.... :crying:

Mobo is about 150 - 200.

Orange were selling S2 for about 240 €(or whatever equates to £200) 3 months ago.
Id sell your phone on ebay as you should get at least £100 clear, then that means you could get a brand new phone with warranty for £100 difference, or maybe a good bit less.

Nexus 4 it is!!!

[Q] Replacing Motherboard

My S2 recently stopped taking charge and I was unable to turn it on at all. Tried the usual stuff, different battery/charger etc and nothing worked. Sent it back to Samsung who noticed it was rooted and told me to do one basically, wanted $400 to repair it because the warranty was void.
They did however tell me that the main board was fried, so got myself a replacement off ebay and have just fitted it but still nothing. Just wondering if I replace the main board with a new one, will I have to re-flash Android somehow? If so, how would I go about doing that? USB Jig?
Thanks in advance!
sounds fishy,
how would they no its rooted if the main board is fried.
but if youre 100$ sure you got a working board, you might have a dead screen or something els thats not working, cause I can power on the board itself, without the screen ..

Mmm, I don't know about that. He would have heard the boot sound. Also he should be able to connect to a PC.
Sorry, scrap this. I just had a COMPLETE blonde moment. Opened it all up and managed to put in the same faulty motherboard haha! I have no idea how they knew it was rooted by the way, they did though and they were having none of the warranty repair. So bought myself a new motherboard AND the Pro Tech Toolkit off iFixit for half the price Samsung wanted to repair it. So here's a big **** you to Samsung.
In answer to my own question, no you don't need to flash Android to the motherboard, it's already pre-installed.
Thread my be closed if you so wish, solved.
So how much did the total repair come to?.

Well you could do it a lot cheaper than I did, I went a bit overkill buying that toolkit. http://www.ifixit.com/Tools/Pro-Tech-Toolkit/IF145-072
But the new board cost me about 150 off ebay and the toolkit was 60 so 210 in total.
Nothing wrong with buying that toolkit-will be handy for future.
Strange though how they managed to suss out it was rooted.
Yeah, I have no idea how they managed it. There must, be something at low level that flags it.

[Q] Dead s2

Hey guys, sorry for another topic, however I actually do know what is wrong with my phone and know it needs to be JTAG repaired..
however... I was wondering if anyone knew the root cause of this (no pun intended).. I was flashing JellyBam v5.0 (custom [email protected]~) and mid installation, phone froze, powered down and is now bricked. Any reason why it would do that mid install? Battery was 95%+
cheers

Please state more details. Rom, kernel, modem, odin, cwm, etc
He did. Regardless, none of that info would be relevant/useful in this case anyway, phone's borked.
@OP - Honestly, that's impossible to say. Something hardware related in the phone, something simple like the battery contacts not making a proper connection, something on the PC side even (temporary issue with the connection b/w the PC & phone) ? The possibilities are endless.
Have it looked at by a JTAG repairer & if that can't be done, maybe try and source a motherboard from a donor phone (broken screen or whatever). That will be the cheaper option than having Samsung replace the MB if it can't be JTAG'd, even if you pay a local mobile repair shop to install the 'new' MB (if you're not confident enough to DIY).

Yeah you are right it could be anything happening within the phone without my knowledge, luckily phone was connected to mains when i was flashing using CWM so no problems there, but i don't think i will find the reason why it actually happened as you said the possibilities are endless
I'm trying to get in touch with a place that does JTAG repairs at the moment, however im just scared they say it can't be done. Havent really got the money to fork out for a new MB. I bought the phone second hand last year (april) where i was told it was only 3-4weeks old however had no old purchase details. Is there any way for me to check if the warranty is still valid or does it become void after resale? Thanks
There used to be an online warranty checker on one of Samsung's regional websites (can't remember which, maybe someone else does ?) where you could put the serial number in & get the warranty end date, but I recall people on here saying it either went away or didn't work anymore at some point last year.
But I doubt you'd get warranty service without the original receipt anyway, and even if you had it, I'm not sure the warranty is transferable beyond the original purchaser (Someone else please correct me if they know of cases where the warranty has been honoured regardless, I realise this might vary from country to country).
Unless the phone has physical damage as opposed to the NAND simply being scrambled beyond all recognition which normally happens when a flash goes wrong like that, you'd probably expect it to be JTAG'able.
If it's not, as I said in my PP, a board from a 'donor' phone would be much cheaper to both buy/have installed than paying a Samsung authorised repairer to put a new MB in (apparently they charge in the vicinity of half what a new phone would cost retail).
Edit - Re: getting a 'donor' phone for the MB, here's an example of what I'm talking about; no doubt you'll probably pick one up cheaper, just thought I'd give you an example of what to look for if you end up needing to go down that path.

I think you're right on that one, if i don't even have proof of purchase then I don't think warranty will be valid. Thanks anyway on that behalf. Yeah it is only that one issue nothing else is wrong physically so i am hoping for the best and do believe a JTAG should get me out of this situation without a problem (fingers crossed).
On the topic of a replacement motherboard thank you very much for pointing me in the right direction if JTAG fails. Buying a cheap phone as such is a great idea and taking a working motherboard for a lot cheaper than RRP is wonderful.
Thankyou very much for your input & help ::highfive:

It happened to both of us whilst installing JellyBam v5, so surely there must be a problem with the ROM? We encountered the exact same issue 100% and are both left in the same position now due to the ROM

I have the exact same problem yeah, but i know a friend of mine who used the same ROM as we did.. it worked for him though
Always try a Jig before JTAG, no harm there.
If warrantu isn't voided, make sure it's really bricked so you can claim it with the "I was updating it via wifi and dropped dead" rutine.
No probs. Just sorry we couldn't be of more help. Best of luck (Hope it ends up being easily JTAG'able for you).

[Q] Can you break your android os of a S2?

So maybe the question from the title is a little bit unclear.
The problem that i had with my phone is that one day, i got a message that a new android version appeared(4.1.2)...and obviously i clicked to download it. After the download and install when it was time to enter in my new version, a screen where a password was required appeared, saying something that my phone is encrypted, and a pass is needed to make i work...Problem is that i didn't have a previous password...
So anyway i restarted the phone...and android didn't even brought me to that screen...it just wouldn't load...So i decided to take matters in my own hands (not the best decision i made that day)...
I searched online how to do that...i found about odin..installed it ...and then tried to install android...Problem is that odin gave me errors when trying to upload the kit or something (i was in download mode with the phone)..when odin gave errors i either disconected the cable from the phone, or in some cases i got pissed off and removed the battery...
My question is...could i have broken my phone permanently by doing that ? Like i don't know...in a way..that neither an expert could fix it?
Thanks
You can scramble the NAND so badly it has to be replaced if a flash goes bad/you flash something you shouldn't be flashing (or if you do dopey things like pull a USB cable in the middle of a flash), and the way that's done is by replacing the motherboard, so you can certainly cause damage that costs money to repair, but it can pretty much always be repaired one way or another.
I seriously doubt you could bork a phone completely beyond all repair via firmware/software & without physically damaging components.
No physical damage was made to the phone...
Assuming all the alien language things that you said ...so the worst case scenario...do you have any idea how much a new motherboard would cost?
Varies widely depending on country/how much labor costs in your country. Samsung don't sell new motherboards on their own, you can either pay an authorised service centre to put a new one in (most expensive option, you normally keep your existing IMEI), or you can get a 2nd hand board from a broken/'donor' phone (How much you'll pay for one again highly variable depending on how much someone wants for their busted phone, search eBay/Google) & either swap it into your phone yourself, or if you're not confident with that sort of thing pay a local mobile repair shop to swap the boards for you (least expensive option, your IMEI will change to that of the phone the board came from).
Edit - If what I said in my PP was 'alien', I'd suggest you shouldn't have been messing with your phone in the first place & should probably avoid same when you get it fixed as well.

Long story short, Yes your device could be "Broken" in such a way that the only option is to replace the motherboard. You atleast tried reading and doing something, dude there are several thread regarding this matter try different strategies, try out your luck, ask questions, but don't get your hopes too high.
Sorry pal, I wish you the best of all the luck in this tiny planet of ours.
Edit : sorry I was too late, I actually started the reply almost after you posted it but I went away had a coffee then completed it.
Edit: lol to actually make a phone completely unrecoverable you might need a sledgehammer, no software related issue in the world can completely damage an electronic device(unless that software was related to triggering a nuke).

[Q] Bricked phone, black screen and can't get into download mode

Hello!
I really hope you guys can help me. I tried to flash a recovery with Odin, and now my phone won't do anything. Its screen stays black, regardless of whether I try to turn it on, or go to recovery or download mode.
Here's some background as to what I did and what I was trying to do:
I had CheckROM RevoHD V6 with CWM Recovery (v5 I think) on my phone.
I wanted to install Cyanogenmod v 10.1.3-RC2.
I followed this guide: http://wiki.cyanogenmod.org/w/Install_CM_for_i9100
However I couldn't get Heimdall to work, so I got Odin v3.07.
I used this guide with the supplied PIT file (this may have done me in).
In the attachments you can see the Odin output.
I waited a good 4-5 minutes, but my mobile wasn't restarting or anything, so I disconnected it, but couldn't get it to boot.
And as I've said before, now I only see a black screen, regardless of the buttons I push. I've tried removing and then replacing the battery, but still doesn't work.
I've read that the USB-JIG is the last resort, but that you need to at least have the screen turn on and display a logo for it to work. Is this true, or can I still in my phone's state of brokeness use it?
And if I can use a jig, this one would be a good one to get, right?
Thanks for any help!
Jig has a 0.000000000000000000000001% chance of working, but try it anyway. If you can afford to be without your phone for as long as the jig takes to arrive, try it, but if you want it fixed sooner than later - service centre. You don't flash PIT's. Ever. This is most likely the cause of your busted phone.
Yeah. PIT is the cause of most phone bricks. I don't want to lead somebody to misinformation, but I heard that you use PIT file only for 3-file stock software when you want to start again with clear fully wiped phone. This is the only situation I heard when PIT file is used.
About your problem. You can buy USB JIG. Like the user above has mentioned you have really low chances to get it working. Your last resort in this case is to try and leave the phone on warranty in samsung repair service. Many people suggest that you should say that your phone turned off during update with Samsung KIES software and has never turned on again even though it has been written on your computer screen that installation has completed succesfully. This might help and they will replace motherboard for free. If not buy new phone. Anyway be patient and wait for more answers.
Dammit. Well thanks for the replies and tips. I hope there is someone who has another tip.
The reason I went with the PIT file as well is because I did it the first time around, flashing the first recovery. So I thought it wouldn't harm this time.
No miracle fixes. If the phone won't even bootloop, you've got zero chance of fixing it yourself. It's unlikely to even be JTAG'able. A Samsung service centre certainly wouldn't attempt one given a motherboard replacement is quicker/easier for them to do (not to mention they make a nice profit margin on the labour/parts). Having mentioned motherboards, you could also source a 2nd hand one from a 'donor' phone with a broken screen & either replace it yourself or pay a local mobile repair shop to do it (will be cheaper than paying a service centre to put a new one in).
Also, if you're lucky, service centre may not notice or care that you've been messing with it/you broke it & might fix it under warranty. Tho anyone here who tells you that's a certainty is lying to you. It's a crap shoot, you might get it, you might not. Obviously if you have no warranty that's irrelevant.
Damn. I was afraid of this. I've contacted Samsung support, but I'm pretty sure they won't do anything since I'm 3 months out of guarantee.
And now I'm looking for replacements as well.
Always seems to be the way unfortunately (this kind of thing happening just after warranty expires). If you've had the phone a while (e.g since it was released), yeah, maybe a new phone might not be a bad idea. But still, get the jig, try it, see what happens. Nothing to lose except a couple of bucks for the jig.
Thanks. Will do, since it's only 4€. And it might come in handy if I replace my phone with an S3, S4 or Note 2.
I feel your pain. I did the exact same thing earlier this year. I didn't think I was still covered by the warranty but when I took it in to the service center they fixed it for free even replacing the main board (I think). Your as well to take it in on the off chance their record still show it as under warranty.
Thanks for the support. Unfortunately the service centre is not close to me, so I'm awaiting a reply from Samsung support and hope they allow me to send it to them.
At least I was just smart enough to make a backup of the files before. So nothing lost on that end, I can get all my contacts, messages, etc. back.

[Q] I managed to hard brick my cousin's GS2, is there a way to unbrick it?

I unplugged the phone while flashing kernel and now the phone is fully bricked. wont turn on, can't access recovery mode or download mode.only thing it does is gets a bit hot when the battery is in or when charger is plugged in. I've read something about a USB Jig. and some people say it works (can fix a hard bricked phone) and some people say it doesn't, so does it work or not ? can anyone confirm this ?if it doesnt, what should I do to fix it ?
Nope. I can almost guarantee a jig will not work (but if you can get hold of one, try it anyway. You might end up being the person with the 'golden ticket').
Besides, it won't 'fix a phone' even if it 'works' (you thinking it will is probably indicative of why/how the phone became bricked in the first place). All it will do is put the phone in download mode which theoretically allows you to flash a stock rom which fixes the phone.
Which as I said is a moot point in this case because it won't work.
It might be JTAG'able, though this is probably a longshot as well. Most likely scenario is a motherboard replacement; either a new one by a Samsung service centre (most expensive option), or a second hand one sourced from a 'donor'/broken phone which you either swap yourself or pay a local mobile repair shop to swap (cheaper option).
NEVER UNPLUG PHONE WHILE FLASHING ! You will instantly end up with a hard brick.
strange mine was flashing to stock when it suddenly got unplugged (loose usb port) but it was okay until i rebooted, he must've flashed it with a wrong firmware
my suggestions is have it JTAGged, however I recommend what MistahBungle said too I had the same experience not too long ago, I flashed it with an incompatible firmware and it went dead, I ordered the usb jig 4 days ago but it still too far to go and I needed the phone for work, I went to the repair shop nearby (not samsung) and they said they can fix it for $20 (rush) $14 if not (but could take days before you can get it) so you can choose anyways just hope that you don't have a corrupt NAND or a motherboard replacement. Heads up and hope for the best

YES I flashed it with a wrong firmware. On"about phone" screen, it shows I9100G. so I thought the device was I9100G which is different from I9100, but when I looked at the back, I9100M !!! and I9100 and I9100M have the same hardware.......

I just contacted Samsung and they said the phone is not under warranty, so get it JTAGed is my only option. and what do you mean by "It MIGHT be JATable" ? might be ?? Are there still chances that it can't be JTAGed ??? XD
Yep. Not all phones like this can be JTAG'd. Sometimes the NAND is so messed up not even a low level operation like a JTAG is possible. In these cases a motherboard replacement is the only fix.
