Hello all,
over at android-hilfe.de is the home of the A210 Cyanogenmod port. Some time ago we discovered that the A210/211 uses the Samsung MAG2GA eMMC chip. According to EMMC Bugs this chip is affected by the TRIM bugs that plague a number of Android devices.
This would explain a number of bricked devices that users experienced with LagFix. Unfortunately not using TRIM means that the tablet slows to a crawl after some time in use.
Questions: Does the A510/A700 use the same eMMC chip? If so, did you work around the problem? How?
It seems that the 2012 Nexus 7 which uses very similar hardware is not affected thanks to a patch in the eMMC driver. Unfortunately the A210 kernel maintainer informed us, that the A210 uses a different driver, so the Nexus 7 fix is not immediately applicable.
Regards
Joerg
Thanks for the info, maybe this explains why my beautiful clean a700 is now a nice clean brick. That is if its the same chip.

I think it is. I found this post from pawtip, where he writes: "FStrim will have no effect on our device since I've disabled TRIM support within the kernel, as it is this command that causes bricks on our device. (There is a bug in Samsung's EMMC firmware.)"
I'm still curious how the 2012 Nexus 7 can safely use TRIM (it's baked into Android 4.3) and whether it is possible to adapt the fix to other devices.

According to Samsung, only secure trim is broken and normal trim can work fine. But I'm not going to risk slowly bricking a lot of tablets by enabling it.
The bug will slowly break the eMMC which leads to freeze when the problematic block is read. Wiping caused a lot of brick because the entire partition is TRIMed. E.g. If the bug is present, enabling TRIM for files may not brick it right away, but may brick it one year later.
So would it be safe to say that once the a700 (like mine) is now in apx that an nvflash if it was available would be of no use as the emmc is now physically damaged.

Not physically damaged. But yes, it's not fixable. There's a lot of posts about this, so please search if you want to know more.

But what about the original nexus 7? It uses basically the same SoC and the same eMMC. And yet there is lots of praise for the way TRIM in Android 4.3 makes it fast again. Why is this possible for the Nexus 7 but not for our Tegra 3 Acer tablets?

It's a risk issue. Google has exact information from Samsung about what works and what doesn't. They can also probably replace eMMC chips if they beak them. If I break my tablet from experimenting, I can't get it fixed without spending a lot of money.

you need to run this harmless read-only command from within terminal on the device or from adb on your PC (with device attached - and correct drivers installed) see links in my sig.

We'll my phone has a so-called bad chip and I've had it since April (over six months) and it's still up and running, you just mustn't do daft things like pull battery etc....although I did that many times, before the community discovered that it was so risky!
There are guides on what best to do, in order to avoid the chance of any issues!
If you did "fry the eMMC chip" there is still some possibility of a warranty return.
Is there actually any evidence that it is a particular type or brand of eMMC chip that causes the problem?
My engineering experience would lead me to also look for a weakness in the design of some associated circuit (i.e. locking out write ability to the chip when battery voltage is below usable value).

Yes if you look here in the forum you'll find the names of the bad chips.
Often times in the world of media, the first to the story gets to claim they were first. They get the worm, and they get the page views. And we won’t say that page views aren’t great; they are. They end up helping to pay the bills that mount when you grow. The obvious downside to that, is often times that same media outlet can fall victim to their own success, and in turn report on things that aren’t actually real. We’ve done it before, and we’ve had to step up and admit it.
At XDA, we take pride in the fact that most of the mobile development news originates here. We are the source that all others report on. We also take pride in the fact that while we may not be the first to the news, we endeavor to report the real story after it’s been tried, tested, and verified. After all, we are the source.
Recently, news went around the internet that the new darling of the mobile world, the Samsung Galaxy S 4, had been rooted prior to its release. Generally that is great news, but in this case the person who did the “rooting” didn’t have the device to test the process. In many cases, like previous versions of the Galaxy series, that is OK because the way to root Samsung devices has been the same via repacking Samsung’s firmware package with su and then flashing via ODIN. While that old way worked, it doesn’t work on the new S4 as XDA Recognized Developer Odia proved in a thread similar to the original “root” thread.
What is different about the S 4 is that Samsung utilizes a new security feature to enable BYOD to make the S 4 more palatable for the Enterprise customers, and that feature is Samsung Knox. Without going into a lot of detail, Knox effectively isolates your personal side of the device from your companies private side.
XDA Elite Recognized Developer Chainfire began toying with the Qualcomm version of the Galaxy S 4 (GT-I9505) back in early March, and immediately began to have issues with the “tried and true” process for rooting previous Galaxy devices. He noticed that while you could “inject” the su binary into the firmware, the device would immediately reboot when that same binary was executed.
After much testing, Chainfire figured out a way to root the device using his tried-and-true CF-Auto-Root process and posted the method in this thread. Be warned that this currently only works on the GT-I9505 (Qualcomm LTE) version of the S4, with Odia finding that there are issues with the Exynos 5 Octa version. As is always the case, be warned that there is a risk in performing any procedure such as this on your device. Let’s hope that Samsung hasn’t decided to really turn their noses up at the development community.

This time around, Samsung's approach is reminding me of an good old un-hackable Symbian S60v3/v5 devices, Sammy is quickly going in that direction, i will not be surprised when Samsung's devices will be "un-rootable" soon, especially their Exynos chipset's closed sources is clear evidence of what is coming Happy flashing guys

Talked to a friend who sat through a Samsung presentation today about their new devices and the Knox technology. It sounds like they're trying to have an extremely secure device configuration possible - one which might not be rootable and if it was rootable, it'd be fixed pretty quickly.
But from, http://www.samsung.com/global/business/mobile/solution/security/samsung-knox:
In addition, Samsung Knox's Secure Boot technology allows the switch of the secure boot root certificate in a secure manner after the devices are shipped. As a result, customers that have high security requirements can purchase regular consumer devices and switch the root-of-trust used for secure boot to better protected ones.

Click to collapse
It sounds like they don't intend to ship all the devices locked down. Hopefully the carriers don't get any genius ideas about this...
From what I read of this thread and others rooting the S4, what has been rooted is a non-Knox'd device. They seem to be switching that stuff on and off during the pre-release tweaking.
Sorry can't remember the exact naming of it. Though I know many programs (games) don't seem to be on the market for our lovely tablet. Though there is this thing called a Nexus 7 that gets basically all the ones we don't. Would it be beneficial and not cause any other issues that is, to change the ID so the market place reads this as a Nexus 7?
Curious if anyone else has done this long term.
Dont know how to, someone else probably does, but just a warning:
The Nexus 7 has a 1280x800 resolution, which is almost half that of the Infinity. Meaning, even if you buy a game that *does* support Full-HD, you'll still be given the half-HD resolution, as that's what it thinks your device has.
The resolution is also the reason apps aren't available for the TF700. Lazy developers syndrome, it's called.

I think what is that you can get a lot of the unsupported apps through Amazon... Especially EA titles and they work fine. I think developers are unsure if they support it so they assume they didn't. Not sure it's being lazy as much as uninformed.

Wild Blood is example of one of them. Though instead of using a crappy cracked or hacked version to get it to work properly I'd like to use it normally. Hence why I know you can modify the build.prop file (found the proper name finally) but curious if anyone has done it.
Nexus 7 is probably the closest to similar as it gets for tablets. Just curious if someones done it more on a long term basis. I'd just like to switch it once and forget about it basically.
I've tried this and it doesn't work. Google are clever and are working out the device from somewhere else.

Hey,
I come from the HTC One section and so I know the basics about Android rooting. But there are still some differences I wanna know before buying a Nexus 5.
Compared to the HTC One I found here a amazingly high amount of people having the random bricks:
[Q] what is qhsusb bulk ?
[Q] Bricked Nexus 5 doesn't boot + no access adb/fastboot/recovery (corup. bootload)
Have I bricked my N5?
So I don't wanna spam you
Ok, AFAIK these bricks happend randomly and not after flashing something. So their phones just randomly died after working correctly for a long time. Can someone tell me if these bricks could also occure when having an unrooted/locked N5 ?
Or does it only appear to be a high amount of bricks and it actually isn't ?
Thanks for helping me
my 2 cents: if you do your homework the likeliness of bricking the phone (no matter of what you flash) is very small.
all other "random" bricks could be just defective hardware or random issues. that's why all devices have warranty.
advice: keep your phone stock for a few days / weeks. just to test it (in case some unfortunate hardware failure appears you will have a better poker face for RMA). after that you can document / read / learn and decide weather you want to tweak it.

A real bricked device without doing anything is minor for me and all the rest is by doing something wrong, at user level. It's always the same thing for all the devices (I agree some are more concerned than others) but the Nexus 5 does not suffer more...

Count me in as one of the "hard bricked" phones with just normal use and seems to be a hardware failure. I have seen a few similar post recently but doesn't see like a very big number of instances. Mine had the show up in device manager as "QHSUSB_BLUK" issue. I was not flashing anything or using the phone at all. Just picked it up and it was off.

Yep, it stinks but does happen. I had it happen on a different device and have seen about the same amount of instances on a number of devices I've followed. The n5 is no different.
One thing you must take into account is that many people buy the Nexus 5 because it is very much a developer friendly phone; so the percentage of Nexus 5 users who post on XDA Developers and who do things that increase the chance of bricking (such as installing a custom ROM) is probably much higher than the percentage of HTC One users who do the same things.

The n5 is a difficult device to truly brick by flashing things. The ones I've seen that are bricks are failure of the emmc, imo.
a far majority of bricked nexus 5 are not really bricked, its just users doing stuff to their phone without knowing how to recover from their own errors. sure, a few are defective and get bricked on their own, but thats very rare. but the far majority are just user error.
I saw another device kernel flash brick. I assume incorrect bootloader would brick too.
Bricks are caused by 2 things.
1) defects
2) idiots

Yes, but you're still more likely to brick it by messing with the root system than if you just keep the phone stock forever and never even go into fastboot. I'm not saying that the Nexus 5 is easy to brick, I'm just saying that it probably has a much higher percentage of users who are into modding than other phones, I guess you could counter this argument by saying that many people buy the Nexus 5 for the "stock Android" experience though. Your point does stand though, many of the bricked Nexus 5s I've heard of sound like it was due to a hardware fault and not caused by something done with software, you can't expect this not to happen with anything manufactured in mass production though.

The only real manufacturing fault that seems to cropping up is the emmc failure.
But I'd say the most part it is user error.
Many of the bricked threads are actually just soft bricks which can be fixed.
Others are often caused by cross flashing things for a different device.
I've seen people flashing kernels for different phones.
Restoring efs partitions from old to new n5s.
All result in bricks.
The nexus is more open than many other devices.
Unfortunately this gives those who don't know what they are doing the ability to do things they really shouldn't be doing.
As first stated. Failed emmc seems to be the only thing that is a genuine brick. Pretty much all others I think are either not actual bricks or user created bricks.

NOTE- If you bought your device from Europe or the American continent, it might be region locked. This would typically be depicted by a sticker on the side of the box that your device came in. This means that you cannot use it in another region.
Samsung claims that this restriction is lifted after you use the device in the home region for 5 minutes worth of calling, but many users have complained that this did not work.
My shiny new phone came with Android 4.3 but the moment I booted it up, it wanted to update itself.
In mid January, Kitkat (Android 4.4.2) was released for the Galaxy Note 3. If you update your phone, you will probably get to this version.
Should you upgrade to Kitkat?
The only reason to not upgrade your phone would be if you want to root you phone while keeping your knox warranty intact. (We will come to these terms in a minute).
If you don't want to root your phone, or you don't care about the knox warranty, there is no harm in upgrading.
The upgrade brings with it some noticeable improvement in speed and slightly improved multi-window and recoloured status bar icons. If there were any other visible changes, I have forgotten.
What is root?
Root is basically an administrator user in linux environment.
Cool. What does it have to do with my phone?
Hey, no need to get snarky.
Android is basically a Java Interface running on top of a linux environment.
So rooting your device gives you unparalleled access on your device.
You get to modify the system files, play with the CPU speed and the lot.
A million different ways to screw up your phone, basically.
What is KNOX?
KNOX is a proprietary software developed by Samsung. It was released with the Note 3 and even backported to other Samsung devices.
It allows you to run a separate environment for some particular apps on your phone. This adds a layer of security as it allows you to keep your sensitive data in a separate environment.
If you tamper with the phone's OS files (by rooting and such), the bootloader marks your Knox Warranty to be void.
This can also be used by Samsung to deny you warranty.
Once your KNOX is tripped, there is absolutely no way to go back.
How do I root my phone?
There are two ways.
Root De La Vega - This allows you to root without tripping your knox. But it doesn't work on newer firmwares. Visit the link to get more details.
CF-Auto-Root - Works on all devices and all firmwares but trips the knox.
There are a couple more methods of obtaining root, namely Klingo and vRoot, but they are both under suspicion of being malware designed to steal your personal data.
Which is the best ROM for this phone?
Asking such questions. Shame on you.
If there is anything else that you think should be added here, let me know.
First of all, it ships with 4.3, not 4.2.2. Next, there are other root options, like Kingo root. Where you talk about what the phones are called on these forums, you forgot a major distinction: quad-core versus octa-core. Also, it's extremely misleading to say that those are the only reasons not to upgrade to 4.4. Haven't you seen all that drama about apps not being able to access the SD card?!
Please edit this information in quickly. I don't want to see this well-intentioned post doing more harm than good.

The only significant drawback of KitKat on N9005 - no call recording program works without root.

So media players not being able to access media files on the SD card is not a "significant issue?!"

I think no, because the developers app just need to update their app to KK to access SD card again...
But that call recorder problem... I didn't know about that. And I didn't like it too. You never know when you need to record a carrier, boss or even family call to proof something.

Even when they do, they can only access their own data on the SD cards. If I have four media players then I need four DUPLICATE media libraries on my card, which is ridiculous. Actually, they can access it in read-only, which means you need a file manager to create the shared directory and then... OOPS! There's no way to manage the media and make a directory and move them together without a PC because AOSP and stock Android do not have system app file managers. This is a MAJOR oversight.
My last phone was an Xperia with barely any internal storage. When my Amazon MP3 app downloads my purchased albums, Google Play Music can't find or play it because it wasn't included as a system app on my Xperia phone. Furthermore, there is no stock file manager on Timescape. Have you ever tried to use the one included with TouchWiz?! It's laughable! They actually broke functionality with ICS that they STILL haven't fixed (no way to make home screen shortcuts to folders)!
KitKat's problems run a lot deeper than no call recording without root, which was something you were not supposed to be able to do in the first place.
Few people use or expect call recording. Almost everyone with a phone has video and audio players, especially those with a large external SD card.

Another incorrect piece of info:
NOTE- If you bought your device from Europe or the American continent, it might be region locked. This would typically be depicted by a sticker on the side of the box that your device came in. This means that you cannot use it in another country.

You can use it in another country without issue... So long as that country is part of the region your phone is meant for!
You can use a German Note 3 in France without any fear of region lock issues. Just don't try to use it in the US.
Alright, OP: if we are going to make this thread work, we've got a lot of editing to do.

Like I said, it works with existing files as read-only but doesn't work for cloud downloads. For example, Google Play Music and Amazon MP3 can't share downloaded media libraries unless one is a system app. They can share what's already on the card but they can only download to their protected folders which the other app can't see/access.

Updated the CPU cores part, the root part (Though Klingo and vroot are still banned from XDA for being malware)
The SD card issue was sorted in the OTA updates of Kitkat.

Corrected.
The combination of KNOX, Kitkat 4.4.2 Symmy negative features, the apparent region-lock issue not resolved and the inability to revert back to 4.3 is a pretty big reason to look for another brand, anybody agree? What do I need a Ferrari for if the speed limit is 50 Km/h ?

Switching to another brand won't help reverting to 4.3 with Sony or LG is the same thing I know cause I own both of those phones along with my note 3
