I mailed to the developer and got some reply about the app...

Re: eMMC Brickbug Check

"Hello,

I have no way to prove it, I do not have any Galaxy R. Theoretically it should work as it is similar to SII.No danger of that my application produces damage to the phone. It only read memory (should be root); never writes. Without root can not be checked and memory is limited to reporting if memory chip is known to have the bug.The reading of the entire memory should take several minutes and give a result.Please: if you try it, show me the results and I will update the description in Play Store.

Greetings.

Hi,Kindly let us know, If Samsung Galaxy R is supported by your application or not?If not, kindly make it supported.... We will be grateful to you.Our phone has an ICS leak and it seems that some users have bricked their device after installing that upgrade.Kindly clarify on the above.

Regards,

Bhargav Achary,

Xda-Galaxy R Community."

So, I think... We cannot be sure of anything... This is sure that the app cannot be relied upon.

Yeah i am doing it !!

will update with a SS :good:
[Samsung Galaxy R i9103] bhargav143:
I have already done it... Waiting for the reply....
[Samsung Galaxy R i9103] chandrus1983:
Here it is,

tested in ICS.
[Samsung Galaxy R i9103] xlm13x:
My tests are on CM7.2 not ICS.
[Samsung Galaxy R i9103] bhargav143:
I have tested on 4 varoius combinations and then sent the snapshots to the dev... However, according to him... SGR should also be automatically supported because of simmilarity.... Lets wait till we get any response... Btw...

If I am not wrong... We have not received any negative result from the app about any emmc being brickable....
[Samsung Galaxy R i9103] xlm13x:
this app displays unknown chips as sane chips. most of SGRs are based on 0x11 firmware and no one knows that this firmware version is safe or not.

My God... I did not go through this thread and was playing around with phone reaset a couple if times. I flashed ardatdat's cwm rom and again did a phone reset. Luckily everytings fine until now. :eek:
[Samsung Galaxy R i9103] chandrus1983:
even i was playing with ICS and reset in CWM :laugh: till yesterday,

as soon as i saw this, i stopped it,
[Samsung Galaxy R i9103] parajsinghal:
Oh god!!! I can't believe it. I just went to cool off in the Himalayas over the long weekend and here's what I was upto.

So I wanted Voodoo sound for music and didnt want to loose ICS either on the trip. I downgraded from ics with odin 2 times before leaving(zcla1 and xwla4, dont ask me why ;) ). I always do wipe data, wipe cache and dalvik.

So I create nand backups of both ICS and NeoV3 flashed over xwla4 finally and keep switching between roms my entire trip. Atleast 10 times. Again each time I wipe all before restore.

And I come back to read this. How lucky am I? :cool:

Or maybe I will face consequences later :D

[Samsung Galaxy R i9103] vijai2011:
@vipul:Please update op with Do not factory reset or wipe in recovery until the issue is identified completely.And I must say that this applies to both the original leaked fw and other rooms based on this.
[Samsung Galaxy R i9103] Entropy512:
Samsung believes that stock recovery is safe due to issuing standard erase instead of secure erase.

However with secure erase, damage is almost inevitable - If you survive the first wipe, you're far more likely to survive the next, but survival is NOT guaranteed.

Nope. Samsung contact, not Google. No one has heard from Ken in ages... I honestly get the impression something weird is going on in that regard... I worry he may have been punished for the tiny little bit of information he gave us (which he didn't volunteer directly - he didn't mention it until someone described the symptoms and our chip model/fwrev exactly to him), even though it was critical in protecting many devices from further damage.

As to the app - It doesn't need to support any given device - It checks standard sysfs entries that will be in the same place on every Android device in existence. It looks at the chip's name and two digits of the cid string - if you have a known affected chip, it will be detected.

I strongly recommend using Got Brickbug instead of the above app - The above app apparently lists unknown chips as safe, which is not a good way to do things. I'm fairly certain it also lists M8G2FA (some Kindle Fires) as safe too...
[Samsung Galaxy R i9103] parajsinghal:
I can do that tonight. But I dont understand why do you want it? I thought you should not do CWM restrore from ICS and if you are on GB you can install the rom directly :confused:

@All

Hey guys, i have not gone though all the pages but I have not seen any screenshot that is not running 0x11? Right?

Are we all on the same fw rev? That should mean all have the same bug.

Also ppl talk abt 0x19 and 0x25. Do ppl have that when 02/2012 chip are also 0x11.
[Samsung Galaxy R i9103] xlm13x:
Most of all chips are 0x11, and no one knows about this fw that its safe or not, better we stay away from wipes and wait till kernel src is released after that dev will be able to make kernels without emmc cap and than we will be safe.

TILL THAT ALL THE USERS USING ICS, DO NOT WIPE USING CWM, ALSO DONT RESTORE BACKUPS USING CWM, JUST STAY AND WAIT ON WHICH STATE YOU ARE.
[Samsung Galaxy R i9103] vipul12389mehta:
Added in the op.

just lemme know that, is wipe allowed after you have flashed ICS ?? even for the first time (assuming your chip is brick bug).

As of now i have added as 'after flashing ics, you are requested not to wipe data..'

EDIT

@vijai: added in the OP
[Samsung Galaxy R i9103] vijai2011:
You should not wipe once you have entered the ics track.....let it be immediately after flashing or after 10th day....

If you need to wipe,you must use gb kernels.but I'm not sure it works on ics...
[Samsung Galaxy R i9103] selva.simple:
Tested using Got Brickbug app

With reference to the post from Entrophy, i installed the Got Brickbug? app and checked the chip. Please find the screenshot below. :rolleyes:
[Samsung Galaxy R i9103] vipul12389mehta:
from where did you got the app ?? it isint on play store..

please provide the link.. i will test it on ICS
[Samsung Galaxy R i9103] selva.simple:
Here u go buddy Got Brick Bug?
[Samsung Galaxy R i9103] vipul12389mehta:
same here..

verdict: unknown chip...
[Samsung Galaxy R i9103] parajsinghal:
Yeah, thats seems to be the safest thing to do atm. Agreed.

But my question is has anyone seen any revision other than 0x11? If not, then why do they behave differently? Like I have mentioned before I unknowingly did everything thats prohibitted while I was on vacation and things are fine for me(touchwood).

So I am just curious. If anyone has/seen any other revision on SGR please let us know.
[Samsung Galaxy R i9103] xlm13x:
Not only u but many other users have done said dangerous process while on ICS and are safe. Only 2 users have reported bricking their device and they are saying that app shown sane chip for them (but this app shows unknown chips as sane) and those 2 users don't know what mmc fw they were having. Maybe its possible that 0x11 is safe and they were having other fw version or its also possible as note/gs2 guys saying that its not mandatory that first wipe screws ur disk but it could be 101st wipe also.
[Samsung Galaxy R i9103] D™:
Did Factory Reset 3rd time today

Ha Ha Ha Ha..you what i did right now..My chip is Sane bt now I m Insane. I was having problem in Play Store. It was unresponsive. I deleted that one & installed new. but phone hanged every times & I have to hard boot. Then I pushed that file using Root explorer. Again same thing happened.

Then did data / factory reset (1st time today). Wiped everything (having fear of Bricking the phone). again started, this time hanged while starting.. Aaaaahhh:mad:..now did factory reset again(2nd time, again having fear for Bricking the phone):fingers-crossed: but reset somehow. Now, again My phone hung.:mad: Finally, did all data wiped (3rd Time) cause now I m INSANE and flashed Machram ICS ROM & now everything is fine.:highfive:

Seriously, I can say each time my hand was shivering while factory reset. But now until an Update or great Custom ROM willn't be released, I wont touch the recovery.:angel:
[Samsung Galaxy R i9103] vijai2011:
Now I can bet you that you have probably screwed your /data partition but you have just escaped from superbrick.To confirm that,Download any app from playstore and try to use your mobile the same time.If you fell that your phone lags extremely unusual,I can confirm that.

I say this because the same happened to me with my note.I was using my own custom rom had to flash stock ICS for some reason.I did so,did a factory reset(knowing the risk),flashed my rom back and it was stuck at splash screen.But I know that I havent superbricked.So I again flashed stock rom and it was ok now.Now flashed my rom and again the problem.

I thought it was a problem with my rom.So I tried another and same thing.And finally,I understood that my /data partition was damaged but was recoverable.So I flashed a custom kernel with MMC_CAP_ERASE disabled and formatted /data and restored data partition from one of my backups.Now Its fine.

But you guys dont try it because you dont have a safe kernel for now...
[Samsung Galaxy R i9103] mj.vikram:
I can also confirm it buddy because i also faced Phone lag extremely before Bricking my mobile..

Better to be safer side don't touch CWM for some time until some one can release the safe Kernel for ICS...

---------- Post added at 02:49 PM ---------- Previous post was at 02:47 PM ----------

hey mine was 08/11 made and BTW i thought i was the only one who is the other victim of this bug buddy...
[Samsung Galaxy R i9103] vipul12389mehta:
Well my phone lags...while scrolling (lil bit)...so could the reason be slitely corrupt partition ??

i have wipe the data thru CWM while i was on gb...

i had the same lags in ICS too..
[Samsung Galaxy R i9103] vijai2011:
If I'm not wrong,You are the guy who said you bricked your phone through ODIN right?If so,on seeing your confirmation on the lag,I think you have already damaged your emmc.So flashing through ODIN

"should"

be safe.

Note that I said "should".Not It is safe ;)

---------- Post added at 03:00 PM ---------- Previous post was at 02:56 PM ----------

Nope...that should be a normal lag due to busy /data partition and If you did the factory reset in GB,you are safe.

In my last post I meant a significant lag like screen getting stuck where it is and gets unresponsive while any app is being downloaded and installed.....:)
[Samsung Galaxy R i9103] mj.vikram:
So you mean to say that my emmc was already curupted and when i flashed Stock ROM via ODIN its totally stopped working....
[Samsung Galaxy R i9103] vijai2011:
It looks so from your reply to my post...Because the when you superbrick your phone while you still run your os,you could continue to use it but it will lag like a hell forcing to reboot and finally it will be dead.
[Samsung Galaxy R i9103] :
That's very possible and similar things were reported before. It could happen when Odin tried to write to an already damaged partition.

Or exactly what vijai2011 wrote: You would most likely get the brick after next reboot.
[Samsung Galaxy R i9103] vipul12389mehta:
Thanks, was just curious to know...
[Samsung Galaxy R i9103] D™:
Tried nothing happened.. Now till my phone brick and my chip is sane, i will b insane..already installed lots of app again and workig fine till yet.. Even battery backup improve from last time ( means before that mrng instance).:D

Guys i have one doubt/suggestion, Every one is saying that problem is with CWM Recovery only so why cont you all use TWRP v2.2.1.4 Recovery, It is available for our Galaxy R and it has more options than CWM Recovery...
[Samsung Galaxy R i9103] The-Droidster:
I don't think the problem with Recovery x or y. All issues are related to wiping caches or data which affect the emmc chip. So this doesn't change whether you use CWM or TWRP AFAIK.
[Samsung Galaxy R i9103] xlm13x:
samsung stock recovery is safe to wipe :D
[Samsung Galaxy R i9103] D™:
Both of u took me wrong.. Come to u means " Let u know that my phone is bricked". I already knew that if my mobile will be bricked u wont able to help me out. So forget abt paper weight. Lols:p

[Samsung Galaxy R i9103] vijai2011:
So no royal paper weights???that's bad....:P.OK no more OT from me...;)
[Samsung Galaxy R i9103] :
It's much safer but unfortunately not 100% safe. Couple of bricks were reported even there.
[Samsung Galaxy R i9103] Entropy512:
TWRP probably uses the same ext4_utils as CWM... Most people aren't even aware that recovery uses stuff from other repos in an AOSP tree when building. For example, the fix to render CWM "safe" is in system/extras/ext4_utils, not bootable/recovery

Do a "strings" on the recovery binary of TWRP, if it says:

Wipe via secure discard failed, used discard instead

It is dangerous.

Also, even if you render a recovery safe, flashing ZIPs can still do damage if the ZIP has a bad update-binary.
[Samsung Galaxy R i9103] vijai2011:
Epic!!!entropy,could we use adb to change roms by removing and pushing /system files???will that be safe?

No buddy not frm my side atleast. Bt u can use ur note-a-book as like u can..:p
[Samsung Galaxy R i9103] amitjoel:
Guys have any of you tried porting the stock ROM on the mazel ROM , cos the forums is now full of reports of devices getting bricked.

I want to know whether it is safe to port the stock ICS from the mazel ROM
[Samsung Galaxy R i9103] parmarket:
Mine was bricked due to this reason. phone was not booting. SSC replaced MoBo and took 21 days. and as a newbie m scared to flash ICS :(
[Samsung Galaxy R i9103] selva.simple:
Yes Buddy. You can do. But its not porting. You can either flash ardatdat's CWM version of ICS or restore Macram's version of ICS via CWM. If you gonna flash, wipe data being in GB and then flash ICS. Do not do Data wipe in ICS.:cool:
[Samsung Galaxy R i9103] emanoj.i9103:
Do we have a sure safe way to downgrade to GB from ICS? I have searched through but couldn't find anything that says conclusive. Also, request users who had succeeded with the steps to follow, but yes i'm aware bricking can happen 1st or 100th time. :)
[Samsung Galaxy R i9103] vijai2011:
Yes.I have a method which worked successfully in note and s2.but don't know if it works here.I need a brave person who doesn't bother about the brick to test it ;)

Hey Guys, Today i gave my mobile to SSC and they told that its Software problem and asked me to wait for half an hour and they didn't check any thing like Custom Binary count or anything....

After half an hour i asked them the status and they told that some problem is there with Hardware and asked me to wait for some more time, then one guy (may be supervisor i think) came out and asked me how it happened and i told yesterday night i found it was switched off and i thought battery is drained out and i charged it and tried again but still its not switching on, Then he told some problem is there with Mother Board i think so we need to replace..

Then in front of me he called some one and asked about Galaxy R mother board is there in stock or not, then he told me to collect my mobile on this Friday :angel:...

So don't worry of bricking your mobile just flash what ever you want if you are in INDIA...
[Samsung Galaxy R i9103] vijai2011:
But there will be problem if anybody says it happened due to flashing ICS ;)

So you are safe as long as you lie to SC....
[Samsung Galaxy R i9103] vipul12389mehta:
Hahahahaa...

Dey never check for such stuff...

I had visited ssc twice for mbd prob..they just saw d prob n considered it...

U hav nly one thin to b sure that the problem shld occur in front of their eyes....dats it n u r straight thru..
[Samsung Galaxy R i9103] D™:
Dont worry now, Samsung open source has release update for ICS too..

"GT-I9103_ICS_Opensource_Update2.zip" that a file of 183MB there. Our devs can download that file & start working on.:cool:
[Samsung Galaxy R i9103] vijai2011:
Great.Now devs can disable MMC_CAP_ERSAE for safe wipes....

And guys for the guide to safe flash:

Flash a GB kernel,boot into recovery,flash any rom.GB or ICS.Its safe to wipe in gb kernel.But once you flashed ICS you arent safe.If you need to wipe again,you need a GB kernel again.

This was the method we used in Note to wipe when had not got a safe kernel.I need someone to test it to work before everybody tries it.Because I'm not sure if it can work with SGR.

I didnt open a thread for this because the guide is just two lines and dont see a point to start a thread for this.And If anybody plans to create a new thread based on this,Please confirm it with me first.

[Samsung Galaxy R i9103] selva.simple:
One Question buddy. You have said Flash GB kernel first (i assume you asked flash GB kernel being in a ICS ROM??) I like to know If done so, will it boot (even in case of Note). And in next step is flashing GB or ICS ROM. Hope u mean to say do the wipe data and flash any ROM (GB or ICS). Right? Because after flashing the ICS ROM over GB kernel, the kernel will always change back to ICS kernel and so we cannot do wipe data afterwards.

So My understanding is (Being in a ICS ROM with ICS kernel),

1. Flash GB Kernel (only doubt is will it boot after this flashing )

2. Wipe Data

3. Flash any GB or ICS ROM

[Samsung Galaxy R i9103] D™:
YUP YOU CAN & ASK TO ALL DEVs WHILE PM THEM TO WORK OVER THIS RELEASE..:p
[Samsung Galaxy R i9103] :
I am afraid removing the flag can be still not that simple :(

In regard to the method...so we did exactly the same thing in case of S2. Kernel replacement makes the trick here.

We flashed either safe kernel or safe firmware via Odin. If you want to flash safe gb-kernel (no wipe zip) via CWM (which I do not recommend) make sure you restart recovery after kernel replacement, (before you wipe).
[Samsung Galaxy R i9103] vijai2011:
Man It should be me how have to say that.There is a reason behind for not putting it OP.

Just think what if it doesnt work and people brick there phones relying on it???Could you take the responsibility nor me???Nobody can.Lets wait till someone confirm it.No harm intended ;)

[Samsung Galaxy R i9103] vijai2011:
How do you say its not easy???Now almost all kernels for note has MMC_CAP_ERASE disabled.You can have GB kernel as reference,Because GB kernels too has this flag but disabled.

Ok first sorry If I have been harsh.You must notice that In my post I said donot create new threads or use this without my knowledge.And That is why OP asked me and I said to wait till its been confirmed.Because we are not sure if it will work or not.
[Samsung Galaxy R i9103] selva.simple:
To make a conclusion to that, i have tested your method in Galax R buddy. I found that i had a GB kernel in my phone. So why wait till i reach home. Tested now itself. I tested two rounds. One is for getting ICS via CWM flash and the other is for getting ICS via CWM restore.

First Test:

1. Flashed GB kernel

2. Rebooted to Recovery

3. Wipe data

4. Flash ICS by CWM flash i.e., "Install from Zip" method

5. Reboot

Second Test:

First Three points are same. and finally Restored a nandroid backup of ICS i took earlier. Reboot

In both the method i was able to boot the phone and get the ICS ROM and ICS kernel. To add more,

After both boots, I tested the system apps and data apps - mainly Play store, Gmail, Music player, Gallery, Camera for any FC issues. Everything is working perfectly and no issues created apart from existing issues of ICS. :cowboy:
[Samsung Galaxy R i9103] :
And this is how it is for S2 too...but it concerns unfortunately only custom kernels and not the stock ones. I am not a kernel guy, but as far as I remember none managed to simply disable mmc_cap_erase in stock kernels for S2. All custom kernels were built without having it enabled. I may be wrong of course, but I read somewhere in thread devoted to our infamous XXLQ5 leak that it's not that easy procedure. It's best to ask Entropy512 ;)
