[Android Q&A, Help & Troubleshooting] ricco7:
I've seen the other thread in xda forum that solved this problem and it's because of the preloader file but thing is which preloader file that solved this DRAM failed problem. Anyone? Please.. share the link or files included the steps?

Solution that I've already try and end up error.

- try other S820 Stock ROM , load up in SP Flash tool and end up with same error "DRAM Failed"

- take out the batt. plug in back after hit the "download" button from SP Flash tool and at the same time plug onto usb while pressing power + vol. down @ both vol. button and end up with the same error.

p/s : in my case, the usb drive is well connected and recognize by my laptop/pc desktop and I'm pretty sure that this has nothing to do with the usb driver cause my laptops still can detect my phones (com port).

Problem Solved.

I've download several files and my phone turn on back. Follows below step if you're having same problem as mine.

Problem :

Phone is already update to a new version 4.4.2 Kitkat (don't know which or what rom since this phone is not belong to me) and from what owner tell me is that this rom that installed has no gapps and he tried to install the gapps.

after flashing it, phone become dead and won't boot even can't see the bootloader. Just nothing if you hold up the power + vol. down / up or power + vol. up and down.

When plug in phone to pc / laptop, phone is detected by Lenovo usb port or MTK usb port.

Solution :

*IMPORTANT* make sure you came from what version. (mine is 4.4.2 kitkat)

Things that you need -

sd card (just enough to put the required files), usb cable, SP Flash tool v3.1328.0.183, preloader.bin file, S820_ROW_S119_130922 files and S820 Multi language files.

1. Download all the requirement files.

S820 Custom Multi language and pre_install_rom v9 here

preloader.bin file here

S820_ROW_S119_130922 here (login and passwd can be found here)

2. Extract the S820_ROW_S119_130922 files and extract the target_bin.zip files.

Then extract the Pre_install_rom v9 and rename the folder as target_bins. After that,

extract the preloader.bin files and put it on the target_bin folder. (Don't worry as in target_bin folder already has the preloader_S820_ROW.bin (119kb) ). Done extract the files, check your phone either your machine detect it by name MTK usb port or Lenovo usb port. If it is MTK then we're good to go. ( If other than that, please uninstall any other lenovo driver that you already installed in your machine. Restart machine and check again whether your machine recognize it as MTK port or Lenovo usb port. ) When you done with this, unplug your phone from your machines and leave it aside.

3. Run the SP flash tool (admin rights) and select the MT6589_Android_scatter_emmc files that located in target_bin folder. Tick the DA DL with all checksum. Then copy Checksum files in folder target_bins and paste it on target_bin folder and on SP flash tool click download. Let it load for a moment until at the bottom of it (EMMC) you see "searching".

4. take out your batt. and plug in back then plug the usb cable to your machine and wait for the sp flash tool detect your phone and start the flashing process. After done flashing, now your phone has the CWM recovery. Unplug the phone from machine and leave it aside.

5. Copy the yaaki_v9_lenovo_S820_KITKAT_4.4.2_rooted files into your sd card and plug into your phone. Press and hold the power + vol. down + vol. up and wait until you see the Lenovo logo then you can see the CWM recovery. Go to install from sd card and select the yaaki_v9_lenovo_S820_KITKAT_4.4.2_rooted files and flash it. Wait until the process finished and after it finish installed, go back and reboot system now and choose NO for disable the CWM recovery flash.

6. Wait for around 2 - 3 mins. for the updated apps. Phone rooted + gapps + custom CWM recovery.
