Becouse you are in Wrong thread, here is only for "No P.Name" repair.

If you EMMC is Dead or Broken read Sticky Thread for Shorting NAND TP to GND and Write "Firmware + Format" and itc... move a litte please.

iam so sorry

[sumit070]

all 8 steps gone fine but set still dead......what to do ??/
here my scan emmc log of boot partition 1

[allumts]

This Thread is for N7100 EMMC only for "P.Name" lost repair.

EMMC you showed above Isn't N7100/i9300 EMMC, so i will know what Wrong you have flashed in this Wrong EMMC "V3W00M"????

[sumit070]

yes bro i know this thread for p.name repair,
and u r wrong bro its n7100 emmc ...

Yea...if want help listen carefully, if no use Search button.

I9300/N7100 EMMC is: KMVTU000LM-B503


Right Procedure is This: http://forum.gsmhosting.com/vbb/f609...tures-1945278/

Of course with N7100 Dump file.

It's all.

So, who was wrong? lol next time first of write this:

and u r wrong bro its n7100 emmc ...

Ceck carefully what's EMMC for I9300/N7100.

Now loock in all Fw Update that you have in you Atf Box, if find "Firmware" for this EMMC: KMV3W000LM-B310, can use, "Linked" above procedure Step by Step where's "Boot1, Boot2, User Area", if need also "Ext_csd", is you problem find this Dump or Read from Same working phone with this type of EMMC that REpeat ISN'T for N7100 Original.

It's all.

bro yes its backside written n7100 and i am sure its pcb of n7100 but i dont know why its emmc is KMV3W000LM-B310 and i do all steps one by one 1st i do emmc update and format also write all files one by one and its done without any error but set still dead and now i returned set ......

anyway thanks for replying and supporting..always proud to be atf team

[allumts]

Hello, no more other way, it's very clear, if you have this EMMC: KMV3W000LM-B310

Cannot Use Fw of other EMMC for Original I9300/N7100: KMVTU000LM-B503

Shure in this phone is been replaced EMMC and for restore isn't enough read in the Sticker or anywere, phone with EMMC connection is been detectet with KMV3W000LM-B310

So you are obbligate to write this Fw for this EMMC type, i've seen the error since the first screenshoot you have posted.

80% of these problematic phones need emmc chip replacement.

this means you only have a 20% success rate on whatever box or tools you use.

the emmc firmware of samsung vtu00m have serious flaws and bugs and after analyzing the said firmware deeper, i even found that it has a self-destruct sequence. It means that the emmc has a built-in command to kill itself!!!

i don't know if samsung uses this "self-destruct" command and i am not accusing them that they use this command at all. I am just saying that it is there and i have confirmed that it is the one of the reasons why the emmc will loose product name in cid[103:56] (this is not product name in bootloader... This is emmc product name only).

So in summary:

1. You will not repair all emmc problems for sure.
2. If you get 10 bad phones, you will maybe repair only 2 of them (more than 2 if you are lucky).
3. Even after you repair the emmc, it will die again after a few days, weeks, months etc...


so without further delay, here are the tools you need:

1. Atf box + binary repair files for n7100
download here:
emmc repair files by d18.builder - 4shared

2. Atf emmc adapter (i used smartgsm adapter)
3. 2 pieces 100 ohms resistor 1/4 watts
4. Soldering skills


step 1: Modify emmc adapter (add 100 ohms strong pull-ups)

so here you will see that i added 2 resistors (100 ohms) to the cmd and the data0 of the emmc adapter. Both of the resistors act as a strong pull-up to 3.3v.


step 2: Connect wires to the emmc on the pcb

red = clk
yellow = secondary clk (not needed if using emmc adapter)
blue = cmd
green = data0
pink = 2.80v

now here you will notice that both vccq and vcc are connected to 2.8v. The actual voltages used by the n7100 is 2.8v and 2.95v respectively, so 2.8v on both power sources should do just fine.


step 3: Connect emmc adapter to atf box and perform "normal factory erase"

what this does depends on the actual emmc specs version of the emmc. It may erase user area, boot1, boot2 and rpmb or it may just erase user area and nothing else.


step 4: Perform "samsung factory format"

what this does also depends on actual emmc specs version... Check out the screenshot and logs to learn more.


step 5: Perform "write ext_csd backup file"

just write back the first (oldest) ext_csd backup file for your emmc. All ext_csd backups are saved here:
c:\advancebox turbo flasher\emmc\ext_csd\


step 6: Perform "write user area"

just follow screenshot...


step 7: Perform "write boot1"

just follow screenshot...


step 8: Final checks
click "scan emmc" and make sure emmc is set to boot partition : Boot partition 1

you should see something like this:

emmc boot information
revision 1.6 (for mmc v4.5)
boot partition     : Boot partition 1
partition access   : R/w user partition
perm_boot_cfg_prot : Disabled
pwr_boot_cfg_prot  : Disabled
emmc firmw update  : Disabled
emmc cache size    : 0 kb
super page size    : 3584 kb
hc erase group size: 512 kb
user area size     : 15758000128 bytes
boot partition size: 2048 kb
rpmb partition size: 128 kb

now you can de-solder the wires and assemble the phone to check the final results of your repair.


if you get problems/errors in performing steps 1 to 8, then it probably means your emmc is one of the 80% which needs replacement!


b.r.

i use this same methad but phone after on recovey mode erro show

failed to mount/cache no such file

plzzz sol here this error

I AFTER FLASH N7100XXUFND4_N7100OJVFND3_4.4.2_UnitedArab_4files BUT NOT SOLVE THIS PROBLEM

You problem is "No P.NAME"????? or is dead Boot...i think this second option, so you are in Wrong Thread.
