roms

hi guys sort of a noobish question but does flashing to many roms damage your sgs?

No, it will not.
It is like installing windows or linux on your computer.
You can do it hundreds of time, you will never damage anything.
The best point is that you can always flash back the original samsung rom and have your original phone back

yea i know so flashing tons of roms wont damage my sgs thanks

But be careful with bootloaders.. when flashing these, it might brick your phone.

[Q] Trying to rescue a bricked Note, help is appreciated!

I have a note here...its bricked, the owner tried flashing angelrom ICS, and bricked it.
It gets stuck when it starts writing factoryfs.img.
I have tried properly repartitioning it, installed a stock bootloader from a gt-n7000 stock rom, and that at least allowed me to get back into android system recovery. I wiped the data and cache and tried again.
I tried a stock rom that had multiple parts, and one that had the individual parts. I can flash all of the individual parts successfully but the PDA.
Anybody encounter this, and know a fix? I would really appreciate any tips or suggestions.

Just wanted to give some more information. I followed Ketan's guide to flash to stock rom, and tried multiple stock roms with the same results.
So I also tried repartioning with the proper pit file (the 16gb n7000) and that didn't work.
The only bootloader I could seem to find (because that was the next logical step to me) was "KERNEL_N7000XXKJ1_CL627135_REV02_eng_mid_ship.tar.md5" , would that be compatible with all stock roms or just a specific one?

I am sorry bro. You fried your flash drive, there is no way to revive it. The motherboard has to be replaced.
There isn't anything one can do if you flashed that kernel. If you have warranty head to Samsung service.

Yep, anilisanil is right. People who had found themselves in the same predicament tried absolutely everything, but there was no cure whatsoever. Data partition corrupted beyond repair, not even JTAG could help.
Motherboard replacement is the only thing that can be done.

How the duck is that physically possible? What an enormous embarrassment for angelom. I doubt hell ever post another kernel again...

Yeah...I figured it was beyond hope after reading through a lot of the threads....
I did reset the counter with a jig, and took away the yellow triangle...but I was told samsung won't warranty this model in the USA.
Thanks for your replies!

Just a little query. Whats the actual physics behind this? Like how can some software fry the drive? Just a little interested and wondered how it actually physically happened. Because my assumption before all this was that it cant be truly completely bricked (obviously i was wrong). but wondering how!

Galaxy Mini Brick BootLoader

My phone is bricked by ROM manager. My phone can't boot into recovery mode, downloading mode nor normal phone. The phone charges the battery so there is still hope to fix it. I also have a JIG Usb just incase. if you got any questions you need to ask, please ask. I really want my phone back.

Can someone answer me - WHY are you using ROM manager when it's known that it kills our Galaxy Mini? Is it really that hard to use Odin, or just flash CWM recovery through the stock one?
Guess some people love to learn it the hard way. You have a unrepairable (at least at home) BRICK!

Sorry! Just a thought came to my mind can it b there any solution for this evergreen problem? Like newbies r bricking their phone again & again. ( like warning in stickies) . Just thinking! !! That's all.....

You have no reason to be sorry . It's a great idea to put a warning message about ROM Manager in a sticky. However, i once was a total noob too, and i flashed CWM using Odin, it didn't even came to my mind to use ROM Manager.
Reading a couple of different tutorials and educationg yourself before doing anything is the best possible thing someone can do to prevent situations like this.But, like i said, some people have money to waste

lol ... ROM Manager is screwing up everyones phone. Even my friend's mini bricked. He was unlucky that his warranty had got over. He asked the samsung service center and they told him that it would cost $90 for a new motherboard. He uses his galaxy mini as a paper weight now. Rather buy a new phone than buy a motherboard for $90.
If your phone is under warranty, you can get your phone fixed for free in samsung service center( free new motherboard ). Even I bricked my phone when I was a noob with ROM Manager thankfully my warranty was valid that time.

Although I was able to use ROM Manager with no problems.

One real problem is that Rom Manager comes by default on most CM7 based roms. So most new users while experimenting might brick their phone by accident.

I agree, but nobody forces them to experiment with something they have no knowledge of. Phones are not toys to play with (to some extent )
A big warning in the general and development section would be enough.

Most new users don't browse the stickies, just notice the large no. of redundant and useless threads. They just open the thread pertaining to the rom they want and that's that. It would be nice if each Rom had either the rom manager removed or a warning with the download link itself

never say to anyone that rom manager's brick cannot be recovered in home, it can be
the only step is just press volume down home power button but without panicking, panicking is the main reason of can't able to get into download mode
then just flash with odin, dont think it cannot get into dl mode, dl mode is controlled by bootloader and bootloader is not removed by rom manager

Unsuccesfull flash of bootloader hard-bricks our device, so you can't enter DL mode.
You can always give it a shot with a USB JIG* tho. But in most cases, the only thing that helps is JTAG.
*USB JIG - a 301k resistor between the 4th and 5th pin on the microUSB connector.

Tried that.
I've seen that video like about a thousand times. No luck i even went to a repair men today, he said your phone is dead if it can't go in to recovery menu. Is there any other way i can repair my phone? Sorry for late VERY reply

Yes, either use JTAG or send it to the service center.

Brick caused by rom manager is absolute
Nothing can be done

Sorry you had to learn it the hard way. When you're new in this world it's easy to 'trust' all CM standard apps. Nevertheless: using CM means you're a root user. Your phone is rooted which means you can seriously damage your phone when you don't know what youre doing. That's exactly the reason why your phone is NOT rooted when you buy it, and your garantee is void when you root it yourself!
Some of these apps provide a warning: with great power comes great responsability!
Nevertheless: the first thing i do when i buy a new Android is rooting it! But a general warning is at place: root apps can damage your phone. Especially those to install roms. Even with a proper CWM you can flash a wrong or faulty Rom. The risk of bricking your phone is always there.
So think twice when you buy a new phone and read all about flashing on XDA!

[Q] Galaxy Note Corrupt Processor

I've just got my processor replaced by Samsung. Apparently according to the technician the processor is corrupted. Mine me it cost me almost USD 250 to replace it because the phone has been rooted so its not covered under warranty. I've rooted my phone, flash some kernels (Abyss and latest Franco Kernel) a few times and changed several ROMS (Kingdroid, ROCKETROM). I've no idea how to processor can be corrupted but according to the technician because when i rooted it i deleted some files cause the processor settings to malfunction and therefore processor got corrupted. I' pretty sure i did not deleted any files from the root folders. Can someone please explain to me the truth behind what the technician said. I believe its a whole lot of gibberish. I believe i should be able to change ROMS and Kernels as i please but i really don't want to spent another USD 250 to replace another processor after i changed ROMS or Kernels. Please advise.

If you have ever flashed a ICS rom which didn't have a safe kernel and made a factory reset,there are chances of your getting super bricked.As to confirm that,switch on your phone and see if it gets past the splash screen.If doesn't,its 50% confirmed.
Next is to boot into download mode and flash some rom with Odin.If it gets stuck at factoryfs,its confirmed.Please do note that it may take 10mins to flash factoryfs.If it take longer than 15mins,I'm sorry you have super bricked.
There are guides in general section to revive it.you could refer that if you need

corrupt processor.. ? not sure what he meant by that... u should have asked to give the more info as in if it was an emmc chip issue...
if that was the case possibly a wipe on stock kernel mite have caused it and they mite have changed the motherboard.. which costs around that kinda money if not under warranty.

When i asked him all he said "u rooted ur phone. You could have erase some processor setting files..so processor malfunction therefor corrupted so no warranty". He did gave me back the motherboard though. of course since the motherboard and processor is a single piece therefore the replace it. But till now i still dont know how that happens or what i did might ha e lead to this when i asked the tech he said dont root your and i was lile "duh"

hmmm... not root an android.., its like keeping all the goodies in a locked room... but personally i have not encountered any such problem till now,,, i have unrooted and rooted the phone so many times..
may be a bad move mite have caused it

I guess you had done a wipe on an unsafe kernel which lead to a super brick
I too had the same experience but luckily got it replaced under warranty

He he .. U lucky guy.

After days of searching and googling i believe like some more experienced users here said i might have caught the bug. But what i dont understand is i've also reflash the kernel to Abyss 4.2 kernel that changed my initial affected Kingdroid Rom to Rocketrom in hope to solve the problem, but unfortunately that didnt work. So basically if so unfortunately it happens to me in the future again, i guess ill just have to unroot and rrset the.binary counter..but by then the warranty might have expired already.

Nope never oc my processor n ive always flash kernel from normal odin. Dont know how thos affected the emmc bug

Your technician is partly credible when he said you fried your procie....
perhaps he wasn't keenly elaborating it but he may have meant it to be your eMMC chip on your Note.
There are myriads of discussions already all over our beloved Note's forum regarding the eMMC chip which has most high end experts believe to be a faulty chip case and so henceforth, this chip would be toasted when a right scenario or pre-conditions are met thereof,, would trigger the superbrick bug.
Your tech guy might not be good in the right explanation of words.. but he is partly good in saying your 'procs' were fried... What I don't agree on him was that it was because 'you root' your phone... rooting does not in anyway enable the eMMc bug.... it is thru using an unsafe kernel and doing a full wipe of your phone that triggers it. Some are lucky they're not bitten first time when doing the wipe (with an unsafe kernel), few are not that lucky and the minute they wipe their device, instantaneously the bug would be triggered rendering their Note unbootable or stuck at data.img or factoryfs.img.

I have a super-bricked note too. What if I go to them with my counter reset? Will they refuse to replace my motherboard for free?

Well it depends entirely on the discretion of your SSC and the tech handling it. Normally most techs are not that stingy to repair your Note just as long as they've check your warranty and is satisfied that you really did not tinkered your phone. Just act and answer sheeply to them that you've bricked while upgrading thru Kies.
Word of advice. Never ever give yourself away... Never ever instigate in anyway to tell them first hand that you've rooted already your phone or have flashed any custom roms on it. They might think otherwise of voiding your warranty if you blurt them what you really did to your phone. Act and think plausibly.
Kapish? Ok..good.

@OP
don't fret, you'll get your polished Note soon with a brand new mobo inside... So it's all good bud.

there is no way to fire your processor in software level, may be oc'ng it may hurt it, but any modification in software will not affect the processor by any mean, he meant the emmc chip for sure, any way as long as you are using safe kernel, and reading before flashing, you are safe to go, and i think your processor is safe as far as you don't overclock it too much.

Need help to Hard Brick my phone

Yes, you read correct, I want to hard brick my phone not unbrick it but at the same time not leave traces of evidence of tampering. An unusual request it may be, but I have tried everything but just cannot get the damn thing to brick. I wanted to brick it and then experiment on possible ways to unbrick it. And then if all failed, I was going to send it back to Samsung to see if they find any traces of deliberate tampering. Come on geniuses...I know you're out there somewhere

Bingo! Bricked it. I take it there's no way that I can attempt to revive it? Also I hope there is no traces of CWM Rom Manager, Superuser or Busybox

I don't know about the traces. But the only way to revive it is JTAG or replacement motherboard.

Next time, I'd rather make a backup in CWM and then restore it from another Recovery. What this does is delete the boot.img, so now your phone can't do anything and Samsung can't get any logs etc. from the device.
Also REMEMBER! Play dumb when taking it to the Samsung store! Don't mention Roms etc..

Or rename a text file to boot.img and flash it as a ROM. This gives a totally faulty ROM.

Wow. No wonder phone manufacturer doesn't honor warranty nowadays.
Seriously if u want to do such scam u should do it quietly without creating thread asking howto do so.

This is nice.... You can brick your phone in the last month of you year warranty and get a new phone/motherboard
Once my friends phone switched off suddenly... Non rooted stock
It happened suddenly and also out of warranty
She had to pay 5k to the Samsung people to get it repaired... And the plus point she got 14GB internal memory with the new motherboard
Her phone was the Samsung galaxy S i9000
it would've been done in free if she had warranty
So maybe you might get the GT S5830i.. The new version mother board or something

I would have done it quietly if I didn't need the help. Duh! Besides, I doubt this is the reason why they don't honour warranty. I think it is more to do with that they are greedy corporate companies who would rather save at any cost irrespective of whose fault it is. I mean why should they penalise someone because of something someone else done? After all you are all paying customers. They scam people everyday and no one complains. I guess people only complain when it happens to them. You can buy a new phone and have it go faulty within 2 months. Do you think you can get a new phone under warranty from them? No it will be a refurbished one and doesn't mater how much you scream and shout for a new one, they don't care. A neither do I.

No, I think it is the same motherboard. What I don't understand is, whether it is the same motherboard they repaired or a replacement one, as this phone was initially locked to the Three network. I had it unlocked. So a new motherboard would have meant that the phone would be locked again. But when I received it back, it would still accept any sims.
