[警告][Note]ICS内核导致手机变砖的警告

2012/05 21 13:05

DO NOT FLASH OR WIPE USING ANY ICS REPACK

The list of “known safe” kernels is below in this post – there are currently two known-safe ICS kernels, but only two.

These kernels are fundamentally dangerous. Samsung introduced some sort of bug in the eMMC driver that can permanently damage the eMMC flash storage of the phone. This leads to unusable partitions at best, and at worst a hardbricked device. The nature of the failure is so severe that the usual method for hardbrick recovery (JTAG) is unable to recover devices damaged in this manner.

Kernels that have been confirmed affected are:
All ICS leaks for the Samsung Epic 4G Touch (SPH-D710)
All ICS leaks for the Samsung Galaxy Note (GT-N7000)
XXLPY official ICS release for GT-N7000 – at least one hardbrick (chasmodo), 2 people with damaged partitions (unusable /data or /system), at least 1 person with unusable /data after a wipe in *factory* recovery – it’s not just CWM, and one person who hardbricked after wiping in Settings
ZSLPF official ICS release for GT-N7000 – http://forum.xda-developers.com/show….php?t=1661590 and http://forum.xda-developers.com/show…1#post26275391 are the first two reports.
UCLD3 ICS leak for the AT&T Samsung Galaxy S II (SGH-I777) – Other leaks may also be affected
Kernels built using the most recent SHW-M250S/K/L official source code release as of May 3, 2012 – This includes SiyahKernel 3.1rc6 for GT-I9100 (all other Siyah releases are safe)

Damage is not guaranteed – it may only affect a small percentage of users, but even a 5% chance is far more dangerous than the effectively 0% chance of hardbricking due to kernel bugs in safe kernels.
Also, some people will not fully hardbrick – /data or /system will become unwritable, resulting in a phone that can enter download mode, can flash kernels, can write to some partitions in recovery, but is overall unusable due to one or more critical partitions being unusable.

Kernels that have been confirmed safe:
All known Gingerbread kernels for the Galaxy Note and other affected devices listed above
Kernels built from the GT-I9100 Update4 source code release – this includes XplodWILD’s CM9 release and my DAFUQ release, hopefully more kernel choices will become available soon

If you are running an affected kernel:
STOP USING IT IMMEDIATELY. FLASH A SAFE KERNEL USING ODIN/HEIMDALL.
DO NOT wipe in recovery
DO NOT flash anything else in recovery
In general, DO NOT use recovery at all

Right now, what we know:
Some people can wipe with affected kernels as often as they want without problems. Just because you didn’t brick, DO NOT advise other users that they will be OK.
Based on reports from the Epic 4G Touch community, some people can wipe/flash 20-30 times before hardbricking – Just because you didn’t brick once, DO NOT continue flashing with an affected kernel
The source of the problem is somewhere within the changes between I9100 Update4 and SHW-M250S Update5 –https://github.com/Entropy512/kernel…250s_dangerous

What we don’t know:
Exactly which source commit above is responsible
How to determine if a future kernel or source release is safe without putting user’s devices at risk – You only need to reproduce the problem once to be hosed.

不要通过任何ICS泄露版的内核来WIPE或者刷机!

这些内核根本就是十分危险的。

三星介绍了几种在eMMC驱动中可能永久性地损坏手机的eMMC闪存的BUG。

这些BUG,在最好的情况下只会造成一些不可用的分区,在最坏的情况下能让你的手机变成硬砖。

这些BUG的非常严重,用最常规修复硬砖的方法(通过JTAG修复)无法恢复由这些由于这类BUG造成硬砖的手机。

被确认存在这些重大BUG的内核有:

Samsung Epic 4G Touch (SPH-D710)所有泄露版ICE内核

Samsung Galaxy Note (GT-N7000)所有泄露版ICE内核

AT&T Samsung Galaxy S II (SGH-I777)ICS泄露版(版本号UCLD3)内核-其他泄漏版的ICS内核同样也可能会被影响到

受BUG影响的内核就是那些基于最近SHW-M250S/K/L,2012年5月3号官方源代码编译的内核。上述提到的内核包含GT-I9100的Siyah内核3.1rc6版本(所有其他的Siyah内核是安全的)

上述的损坏不敢保证一定存在,这只会影响一小部分百分比的用户,但是由于内核的BUG导致变砖,5%的几率远远比0%的几率要危险。

被确认是安全的内核有:

所有已知的Galaxy Note的姜饼内核(安卓2.3的内核)和其他的基于GT-I9100 Update4源代码编译的内核,这些安全的内核包括XplodWILD的CM9,我(帖子作者)的DAFUQ,希望更多内核选择能尽快的利用起来。

如果你正在使用这些存在BUG的内核:

马上停止使用它,通过ODIN/HEIMDALL线刷一个安全内核。

不要在recovery执行wipe

不要在recovery执行任何刷机行为

总之,不要使用recovery

到目前为止,我们所知道的:

一些正在使用问题内核的机友,任然在随心所欲地执行wipe而没有出现任何问题。这仅仅是因为你的手机没有变成砖而已,不要再叫嚣这些内核没有问题了!

基于Epic 4G Touch区传来的报告,一些机友在变砖之前能执行wipe或刷机行为20-30次,这仅仅是因为你不曾变砖而已,不要继续用你的问题内核来刷机了!

这些BUG出现在I9100 Update4和SHW-M250S Update5源代码之间的某处,地址是:
https://github.com/Entropy512/kernel_galaxys2_ics/tree/m250s_dangerous

我们所不知道的

究竟哪一段代码导致了上述提到的情况

在不把所有机友的机器置于风险中的情况下,将来怎么去确定内核或者源码是安全。

你所需要做的是,知道这么个情况,并告诉周围的人。

另外,转至三星手机论坛HDVS1)官方ICS的基础上刷CM9,必砖!!

2CM9的基础上直刷完整ICS,必砖!!

3)官方ICS基础上刷最新的MIUI,必砖!!

4MIUI的基础上刷官方ICS,必砖!!

5CM9的基础上刷最新的MIUI,理论上可行(并非必定可行)!!

6MIUI的基础上刷CM9,理论上可行(并非必定可行)!!

 

然后据说,请刷任何4.0前,刷回2.3.6,这样理论上就不会砖

    Hi would you mind sharing which blog platform
    you’re using? I’m planning to start my own blog in the near future but I’m having a difficult time choosing
    between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your layout seems
    different then most blogs and I’m looking for something unique.
    P.S My apologies for being off-topic but I had to ask!

    Exactly what I was looking for, thank you for putting
    up.

  4. #-46

    Marvelous, what a webpage it is! This webpage gives helpful facts to us, keep it up.

    Now I am ready to do my breakfast, afterward having my breakfast
    coming over again to read other news.
