Hi everyone!
I'm wondering, how risky it is to flash new firmware to the tab? Is it really brickable, I mean, is it possible to really really brick the tab to a point where it's not possible to fix it? I'm asking partly because I'm a rookie, but mostly because it seems that everyone who manages to brick their tab around here, is somehow able to restore it. Or am I mistaken?
Where I live, the tab has a starting price of $1100. And thats gotta be one of the most expensive bricks in xda history. And if I brick mine, I know I won't be able to resist buying a new one, which adds ut to a $2200 pricetag and a very VERY angry gf..
thanks btw to all of you who make this place what it is
As risky as any other device. Simple. The risk doesnt just lay on the devices shoulders, its the user and the rom maker.

Okay, I'm so confused with the brick-terminology being used here. In all posts regardig new firmware to the tab you'll see at least to guys saying that they bricked their tab. Only to say that they fixed it/unbricked it moments later.
I thought that if you bricked your device, whatever device it is, then it's dead, period. No more usefull than a brick like the ones you'll find in a brick wall, just a hell of a lot more expensive. Heck, the word "unbrick" shouldn't even exist by this definition.
So, let me rephrase:
If I brick my tab, can't I just unbrick it? And if not, why? Is it even possible for the tab to be totally and permanently bricked forever? Is the tab in any way safer to fool around with than other devices? Do we know anyone who have bricked their tab permanently? Should I be afraid of fooling around with my tabs firmware for real?
I think it's just a question of perception on the part of the person who "bricked" their device (the "brickie"? ). If you flash and find that you have what appears to be a dead device then you may well come on here and say "I've bricked my device!". You may then find that it's not bricked at all as there is a way (previously unknown to yourself) to recover. I remember in the old days on here people would pick up "bricked" phones on ebay etc, knowing that quite often they could recover them. It probably still happens...
But devices certainly can get permanently bricked too as you know. Personally, I would only flash if I had confidence in myself that it would work, having read up on the procedure and seen enough working examples. Others may just dive in and see what happens . Only you can decide if it's worth the risk or not, but these days I think it's quite rare to permanently brick a device if you fully understand the procedures and the risks. A stable recovery ROM makes a big difference. Not sure if the SGT has that yet.

It's in the works, just not quite there yet.
As Paul said, there's always going to be a risk it COULD happen. But following documentation and fully understanding the task at hand before diving in helps to limit the risks to a minimum.
Thanks to all of you for enlightening me
When I was flashing the different files to get calling on my ATT Tab I managed to flash the wrong file and get the device not to boot up but there was still the "download mode" to go into and I was then able to flash the correct file. I find it is very rare to actually "brick" a device requiring the device to be replaced or cracked open & reprogrammed manually. Most of the time now when a device is described as a brick it just won't boot the OS like it is normally supposed to.

Lol @ "brickie" - I guess you have to be British to get that one?
As for "bricking" , quite right, the device isn't "bricked" if it can be fixed by the user.
People have gotten sloppy with the term, but really it means that you could build a house with it if it were fat enough, but it's no more useful than an expensive paperweight.
The worst you can do without bricking is boot-loop/no-boot which can usually be fixed. The point is, if the device shows any signs of life whatsoever, it's usually fixable.
I thought I bricked my tab, I got the infamous "phone-!-pc" screen
http://forum.xda-developers.com/wiki/index.php?title=File:Samsung_Galaxy_S_Black_Screen_of_Death.jpg
I thought I was screwed. However, I still had it connected via USB and Odin still running and I saw that the com port popped up. I though, hmmmm
clicky and bam, its flashing.
Got it back.
This was after a stupid botched flash attempt on my part.
So, I think you REALLY gotta mess it up to be proper "bricked"
I did a lots of tries and I thing that is not that easy to brick, but I can give a suggestion: Backup the EFS folder!!!!!!!!!!!!!!
I deleted by mistake with root explorer the nv_data and relatives backups, and I had a corrupted IMEI that is not a brick but I think is one of the bad things (and hard to recover if not impossible if you don't have a backup) because if the carriers ban double IMEI the phone (tab) will not work + is not legal
Forgot to say: seems that some SGS firmware upgrades corrupted the IMEI too, I didn't see something flashing the TAB, but restoring the EFS folder will fix (almost always) the problems
I have not tried to brick my GT, but the JM6 gave me a scare... I have been flashing it for a while now.
The one thing you have to give up for now is SWYPE. I se you have a norwegian flag... And norwegian is not included in any flash I have found. So if you ever decide to try flashing. Say goodbye to SWYPE in norwegian for now...
Yeah, the loss of the Norwegian keyboard is the only thing stopping me from flashing jm6. Lucky for me, I'm very patient.

Apparently, you can brick it. I succeeded !
I flashed with Odin and a custom made PDA package including boot.bin but no repartition.
Odin flashed without problems but the Tab did not reboot and simply 'died'.
Black screen all the time, no recovery/download mode, not seen by the PC, does not charge on ac/dc (neither the charger or the PDA ever gets hot, no sound on connection, ...).
I'm letting the battery discharge completely (but how long can that take when it's not using any energy...) to test again tomorrow but I will probably RMA it on monday.
One thing that concerns me is not being able to remove the battery to force the phone to shut down completely.
As an example when I originally 'bricked' my SGS using Kies, no matter how many times I powered the phone it simply refused to go into Recovery or Download mode. All it would do was show me the two icons on screen.
The only way I managed to totally shut the phone down was by removing the battery and wait 30 seconds before returning. Only then would the SGS allow me to access the 3-Button Recovery/Download Mode.
So..... has anyone come across a situation where you needed to remove the battery and if so how did you manage to recover?

The worst I have done is get the device in the "Phone---!----PC" mode where you can't enter "Download Mode". It seems that simply flashing a new PIT file and then forcing it off, it will then enter download mode again.

A little un-nerving isn't it... I have deep thoughts of not being able to get the Tab to drop out of memory by not being able to remove the battery and flush.

I think that when you leave/turn "USB Debugging" on in Applications -> Development, it is fairly save. As long as you are near a computer with adb installed and you have your usb cable within reach, you can reboot the device into recovery with adb reboot recovery or just reboot with adb reboot.
Another way is of course to let the battery run out of power, charge it and reboot.

Are you saying that the Tab will accept an "adb reboot" in it's unresponsive black screen state or some other? I'v not yet come across a state where just holding power didn't turn it off.

Running down the battery is an option... but it would take an age seeing as you're not doing anything with the phone except looking at two icons on a black screen.

I did . I was fooling around with the button definitions of the tab, I lost all my buttons so to speak (also the powerbutton) and couldn't get into the system. A simple adb reboot got me out of there without any problem.
Yes, I believe adb can connect with the Tab in very unresponsive states and still issue commands. I've seen it also with my old galaxy S. A bad flash and a blank screen still gave me access to the system shell with adb.
My lesson learned is: alway have "USB Debugging" turned on.
Stumbled upon this a bit ago, a company called Mobile Tech is offering an "unbricking" service on all versions of the Galaxy Tab. At the time of this writing they charge $50. I have not used this service, am not in any affiliated with this company and cannot vouch for their work, so beware. Just thought someone out there might use this when other options aren't available.
They have a nifty video up on youtube showing how they do it:
it will be a good help for those who brick their tab because they ain't follow the steps .. thanks for sharing this out
I can actually vouch third party for this service. Have had two friends use it and the device was returned within a few days. If I'm not mistaken, the guy lives in the southern US, but can arrange international he says.

This is cool, but I would recommend trying to go through Samsung first if you are still under warranty. I screwed up my primary bootloader and contacted them. They took care of shipping costs, fixed it up, and sent it back in about a week and a half. If Samsung hadn't fixed it I would defiantly have payed the $50 here though.
WOW, that seems like a lot of work for $50.
Thanks for the info, should I ever screw something up its nice to know there are people out there who can clean up my mess!

Hi spacemoose1
Thanks for link and as always, thanks for honeycomb port. I would like to ascertain the definition of BRICK? with your help, if I may.
(disclaimer: pls forgive my wrong terms or exagerated explanation, but most importantly, pls correct me if I'm wrong)
BRICKed = software total lost, must use JTAG to force revive it, Samsung has it, or buy from web supplier around 300 USD ??? 500 USD ???
JTAG is a device to push software into all newly borned IC. I.E. when factory make IC, it's empty software inside, hence has a special device to push voltage into all sections of the IC, then force the code in.
Another term is ???CRASH??? or ???HANG???, (I don't know) anyway is not BRICKed, hence a reflash can recover it.
Samsung uses proprietary method a lot, not follow conventional, make usb driver very complex. USB driver install EXE around 15MB to 28MB depends on version, ALL work the same.
but, when the device = sgt7 in different state/condition, the driver must RE-ESTABLISH again, or else cannot work.
I.E.
state 1 = "OPERATIONAL"device in android operation, normal use, surf web, phone call etc
state 2 = "SLEEP" device powered off, show battery big icon charging when powered by charger
state 3 = RECOVERY mode
state 4 = DOWNLOAD mode - this is one of the way to FORCE flash to recover, as long as bootloader and something still intact
state 5 = PHONE-!-PC mode
stage 6 = "COMA" device powered off, NO show of battery big icon, even when charger supplied. Don't panic, let it charge fully 4 hours from 2 amperes supply, 10 hours from PC 500mA. It will start again !!!. Battery big icon will appear around 30% battery charged, I know because that's what I saw. I didn't check when it's in 10% or 20%. The 1st time I check was already 30% up from no-boot or no respone.
User need to plug device into PC during each of the state above at least once, in order for various flashing functions to work.
i.e. when it's a newly arrived device, usually install the usb driver 1st, with device state in android OS running properly, then plug in to USB and see "new device detected" installing, pls wait. Finished.
But when flashing via Odin using state 4 = DOWNLOAD mode, user may experience no connection, no COM3 or something. Because device must be unplugged in USB, power-up in state 4 = DOWNLOAD mode, plug in USB, "new device detected" installing = RE-ESTABLISH, done. UNPLUG USB, replug in usb, then COM3 appears FLASH will be succesfull.
same goes for other state.
p.s. many users reported BRICKed but then recovered WITHOUT JTAG is misleading beginners, hence should rename the term to ???CRASH??? or ???HANG???. although some previously use "SEMI-brick", which is acceptable.
stage 3 = ClockWorkMod flashing (super convenient, especially on the move without PC)
stage 4 = Odin / Heimdall both works (still convenient and easy )
stage 5 = Odin / Heimdall both works (still convenient and easy )
???CRASH??? or ???HANG??? or "SEMI-brick" is usually SUCCESFULLY recovered via restock+PIT
(final disclaimer, incase above is correct and help and is copied, pls correct whatever mistakes found, feel free.)

Yeah, warranty repair is always a better choice. But sometimes you've already voided the warranty, lol.
I guess, if u change factory installed rom/kernel warranty gonna be history
thanx for the post ... it might gonna be the last resort...

I pretty much agree, but I might refine:
BRICK= Unit does not power up, visibly charge, reach a boot-screen of any kind including a service or "download" screen. A device in this state requires service from the manufacturer or an individual equipped with the proper tools. There is no other way to recover a device in this state.
SOFT-BRICK= Unit powers up, reaches a "download" or service screen, visibly charges but does not boot into an OS. Crashing, hanging etc. all apply here. It is easy to recover a device from this state so long as one has access to a firmware that was designed for the device and the ability to flash said firmware.
SEMI-BRICK= See soft-brick above
JTAG= Provides access to system hardware by applying the correct voltage to the correct pins in order to push software via an external program.
In regards to the usb drivers, there are only actually 4 states
1. Active userspace
2. Serial gadget mode
3. Recovery
4. USB storage mode
And there is a separate driver for each of these (except recovery) in the Samsung driver package that should install automatically when the device is plugged in during normal use on a stock rom, or with the installation package available on the web.
The rest of it you've got pretty much correct.
Money seems right, but the amount of work that guy has to go thru is amazing, so much to tare it apart, and reassemble. Then again when it is put back toether, he checks it, what if it did not take the fix... all over again.
Hardbricked Tab Save by Mobile Tech
I hardbricked my galaxy tab bought in Cambodia. My little brother open the tab trying to take the battery off and put it back on, thus void the warranty, found him on the Samsung vibrant forum, sent the tab to him got it back good as new. This person is professional, honest and good communication with his customers, you'll be happy with his work, if he can't fix it you get your money back (minus shipping and diagnosis)...Glad he is arround to help...

Nice find. For that amount of effort disassembling, and reviving, $50 is a very realistic price. I'll keep these guys in mind if I run into issues with my tab.
$50 for that much work is an absolute bargain! I wish I didn't live in a country where you get charged $200/hr for someone to pick their nose.
It's actually not that much more difficult than popping an OS install CD into a hosed computer and pressing 3 keys to let it run through the installation after flashing a corrupt motherboard BIOS. Yes, it takes familiarity with the software and hardware, but it's by no means a feat that requires a special skillset.
Granted, few people have JTAG stuff handy, so $50 is definitely worth it if you've hosed your device, but don't make it sound like he's sweating and coding the bootloader by hand, strenuously manipulating micro tools to disassemble the tablet and flipping DIP switches to restore the bootloader. You spend 5 minutes taking apart the tablet, you attach the JTAG cable, run the supplied software on your computer, and sit there recording the screen with your video recorder while the progressbar moves from 0 to 100.
Again, it's worth $50 simply because not everyone and their mother has JTAG hardware sitting around, but by no means is it hard. It's the same reason I can get away with charging $100 to clean viruses off of a computer. People either don't have the tools or don't know how to use them. That being said, I don't know a damn thing about using JTAG to restore a corrupt bootloader, nor do I have the right hardware, so I'd pay $50 if I were ever in the situation.
Edit: And yes, $100 for a virus clean is a lot, but people generally change their mind when I explain to them why they got viruses, as well as installing proper antivirus software and then instructing them on how to avoid infection in the future. I rarely get repeat business from the same customer but I get A LOT of referrals ;p They're happy paying that much when the person educates them instead of cleaning, not installing/explaining, then having to bring the computer in again two weeks later for another wallet-gouge, which most other computer 'repair people' gladly do over and over.
Everything in this world is rinse and repeat... The money comes from time spent learning to use the hardware properly, micro soldering skills (which isn't easy, no matter who you are), confidence enough to offer it as a service, not to mention the couple hundred bucks for the jtag software and hardware.
Now, the fact that if you have your device in a bricked state you likely voided the warranty, it's a 600 dollar brick if your samsung tech recognized it... 50 bucks is a steal to not deal with samsung anyway.
Try to be less pompous next time oh savoir of the hundred bone virus... Your poop stinks too, promise.

I've got to call you out on this one. Mis-connecting or shorting any wires will lead to a damaged PCB and an un-resurrectable TAB. I'm also a Systems Admin for a living so I understand where you are coming from. You must realize that I solder at levels of .1mm in spacing on the Captivate, Vibrant and Nexus S. Electrical engineers and technicians have first hand talked with me about the difficulty of doing this and is NOT something that anyone can do. You'd think twice when you burn up a phone or two valued at $500 a pop trying to JTAG them. There is more skill involved than you would think. Not to mention the liability when dis-assembling the device. JTAG software is decent but it's not fully automated. There are TCK frequencies, RTCK frequencies different PBL partition sizes, full dcc loader read/writes and the requirement of EXACT voltage from an external power supply that are needed in MANY cases. Plus, there is little to no support when fixing a device. This means that if you can't figure it out, nobody else is going to for you. I'm not trying to brag but yet point out that this isn't like plugging in your phone for an ODIN flash. I've taken hundreds of hours of time and 1000's of dollars to create what I feel is the most trusted JTAG authority online ANYWHERE. I greatly appreciate having the opportunity to help the community and enthusiasts in this community. If this was as easy as you are claiming, you could get JTAG hardware and a manual at Best Buy. I have to say you put it best when you said you don't know anything about JTAG... Ok end of rant I was just a bit bothered by your post.
Ok with that being said, thanks for the personal testimonies and compliments. I will be here whenever anyone needs JTAG assistance in the future or around the forums to help answer Q&A when it doesn't require JTAG. Here is a Nexus S promo to realize how tiny some of these things are

Hi guys,
After 4 days of usage, my NEXUS 4 hit a gutter with this infamous red LED flashing issue, aka red light of death...
The phone was bought over eBay brand new, and I tried to solve it with RMA, but since I'm not the "original" purchaser, Google rep won't be able to help me any further...
After doing a lot of reading and researches in various forums, and without any luck with Fastboot mode; I decided to take the challenge and risk on my own by opening the rear housing.
1. Take out the bottom 2 bolts and use finger nail to make a gap at the bottom of phone. Take your time, the first attempt can be a bit tricky.
2. Remove the two bolts that hooked up the battery bridge.
3. Use small force to flick the battery bridge with your finger tip. The battery bridge is like a clip, so don't worry about break the ribbon. Just do it slowly. Make sure the cable is straight and undamaged.
4. Leave the phone rest for about 2-3 minutes, it rests the phone's memory for the battery status. And they push the battery bridge back in. Make sure you feel the clip for it. Don't bolt it straight away, as the following steps might require a few attempts... (but at least worked for me, after about 3 tries)
5. Try tap the power button and volume - key. This might require a few tries, if it doesn't get into fastboot, repeat step4. Trust me, it takes chances!!!
6. If you succeed in step5, plug phone into your computer and see if the phone will be able to install all necessary driver for ADB and etc automatically.
7. If you reach into fastboot mode the rest should be familiar for you. Use Wugfresh or Nexus Toolkit to flash stock ROM and lock the bootloader afterwards.
8. !!!This step might not apply to everyone!!! During the restore to stock procedure my device was stuck at the "writing system" stage.. I used "Naked Universal Driver" to fix it; which was found on XDA. Go to your device manager, and update your driver via using the naked driver. Relatively easy step, but allows me to finish restore!!!:fingers-crossed:
Conclusion: I rooted + unlocked my phone, but after this time I won't do so; as I fear I damage it again... but at least I have a working phone again; despite the fact that I lost a bit of personal data due to last recovery...
And I feel this issue might not only be hardware (assume battery is total joke...) but software side as well. Hence, I am staying away from rooting this time, and hope this post can provide some assistances to all Android lovers.
Cheers!
I've been scared by many XDA users before getting my Nexus 4 (about cosmetic issues and red LED), but after having it for about a month, I've flashed every ROM and recently went back to stock (testing a theory), rooted and back on Xylon again and never had issues YET, I suspect there is a hardware fault on peoples phones that's causing this phenomena
hardware is a definitely a possible cause. but im a bit frightened to mess around again with technology. ..
im not a IT professional, just use the phone for work and basic functions!lol
though fixing it using the steps above can fix it, it still a little inconvenience to open it and play with the battery all the time. its not removable

Hello all; apologies in advance if this is retreading old ground, but I couldn't find anything about this on the forum as is.
So, while taking some video the other night, my Razr M (all recent software/OS updates, stock software + commercial apps , no flashed ROM/no root/hell, I wasn't even using GoLauncher anymore) decided to freak out on me. By the end of the night, it got itself stuck on booting, and by the next day, it's more or less bricked. Called, got my replacement phone from Verizon, but before I ship this off, figured I'd plug it into the PC and see if there was anything I could do to salvage data -- most things are backed up, but the video/things from that day obviously aren't.
So, no screen. When I plug in, I get the little green light intermittently. For fun, I tried getting to a boot screen (Vol down/Vol up/Power), and now I have this fun thing where my PC tells me it's installed "Fastboot SMQ S" drivers, and is "searching preconfigured folder drivers". Every few seconds, the phone's light will be green, a few seconds later, it will go off. Likewise, my device manager keeps trying to recognize a Human Interface Device, and now and then Windows tells me a connected device has failed. (Once every now and again it tells me it can't recognize it, for about a half second.)
I should note that at no time during any of this does the screen on the phone itself give me any sort of image or feedback.
This leads me to think there's still something inside the phone fighting to work -- as stated, I don't need it to get back to functionality per se, but if there's enough left to work with to at least pull data off of it before it clinks out, I'd be quite happy.
This seemed like a question for the XDA folks, even though it isn't mod/dev related, because you guys are usually the forum I read when I have questions, as you all seem to really know the insides of the phones and systems. If there is a better forum/place for asking this question, please just let me know. I'd be grateful for any sort of advice/insight you may have.
Thank you, and have a great afternoon!
p.s. I assume, based on other similar threads, that the whole "stealthily open the case, yank out of the flash and kitbash it into my pc while somehow not voiding the warranty" route is unfeasable/undoable. If this is not the case, I'm game for that. I'm not a phone dev, but I've seen the inside of an electronic device or ten in my time, so I might be able to pull it off.
Hello,
I got an old Nexus 7 from my sister and would like to use, but I cant get it to work. It does nothing, no screen flicker/backlight showing, nothing. The only thing that somewhat works is that I can get ist to show up in Linux as NvFlash with Lsusb.
The Nexus 7 never had a custom rom or root, it was completly stock. It was mostly used in the original dock. I did already swap the battery, I did try all buttom combos I could find on the web, but still I cant anything else than showing up as nvflash. I can hear some noisy if I put my ear near the tegra cpu, once I tried to power it via button pressing.
Do you have any idea on how to revive this thing?
You can try the Nexus Root Toolkit and see if it can Unroot (this flashes the stock os) with the Bricked radio button selected, but I would not be hopeful.

You may have to use nvflash to flash the bootloader. Search with Google. There are some results which may help.
Hi, thank you both for your reply. I will try it next week, since I am currently not at home. @tnsmani dont I need some special files because of the encryption? I havent got those :/

That's why I said search with Google.
So I searched Google, but all the results I found say it is not possible to reflash the bootloader without the blob file since it used a device specific key. I guess I am out of luck then :/

Hi, Nachoztyle...
Mmm, from your description, it certainly doesn't sound promising. If the bootloader is corrupted or erased, the device is hardbricked, and a motherboard replacement would be required to render the device bootable again.
APX/NVflash mode is pretty much a non-starter if you haven't, at some point in the past, created your own unique 'flatline' blobs for your own specific N7.
However...
My own N7, which I sometimes completely forget about whilst it's lying on my desk, frequently runs out of power/charge, and when it does, the device appears completely and utterly dead.
So when I plug it into the charger, nothing happens. This happened recently, a few days ago, actually ~ I tried to power it on, and nothing happened. As usual, I plugged it in to my mains charger; I use an Amazon Kindle charger, output rated at 5volts/1.8amps, which I'm fairly certain is roughly equivalent to the original charger which shipped with the N7 back in 2012.
And nothing happened. I unplugged it and replugged it back in again, several times - and still no screen response.
So, I left it connected to the charger, overnight. The following morning, my N7 booted up.
I've had this happen before with my N7, that when the battery dies, it can take a bit of 'coaxing' back into life, sometimes with several plugging and unpluggings into the charger, and sometimes with different chargers and USB cables.
So, in conclusion then, it might be worth tinkering around with different chargers and/or different USB cables. Even with my 5volt/1.8amp Kindle charger, it can still take a good 12-16 hours before I can actually use it.
Rgrds,
Ged.
Sadly the device was always used stock and the flatline blobs never created.
I will play around with some chargers, I got a couple different ones, including the original one flying around.
