sorry for long reply,
if you got error 8038 while flashing then you must press firmware upgrade button instead of download button. that will solve the problem.

Hi again Andy
When I press firmware upgrade button i have got a brom error : s_ft_enable_dram_fail (4032).
My lenovo s820 has VIBEROM_V1.0_1340_3_ST_820 firmware, is it possible that this is the system issue or maybe different phone version? I found another problem with this phone. When i connect it to MTK Droid tools the program doesn't show any information about the device. Is that normal for that type of phone or is that a clue there is something not correct with the device.

hi,
brom error : s_ft_enable_dram_fail (4032) according to error code, it say that this firmware is not your device, hmm i am afraid that your device is fake Lenovo S820, you can check it using CPU-Z download from google play store or find it on internet for apk and install. see the processor that installed on your device.

gregorecki21

Cpu-z shows correct procesor mt6589, but the internal memmory acording to description should be 4gb and cpu-z shows around 1,5 gb. Another think that worries me is only one IMEI number for 2 sim slots. Is that normal?

Thx fo the link to the instruction. I'm not going to install it at the moment because I'm affraid to brick the phone. For now the phone is working on the system primary installed. I found another thing. In device manager in windows my phone is recognized as PreLoader USB VCOM Port not as Media Tek Preloader. Maybe the problem is Preloader??

First ended with error S_FT_ENABLE_DRAM_FAIL (4032), second with error S_COM_PORT_OPEN_FAIL (1013). Generaly i tried flash 3 different roms (S820_ROW_S119_130922) (S820_ROW_S124_140404) and (S820_ROW_S221_140730). Is there anything more i can do?

Hi,
You said that you have found how to do flashing on device that produce in 2014? Have you do it or not?
First download https://www.4shared.com/archive/-HgttE0wce/preloader.html this preloader, extract it on ROM extracted folder and remove the chexksum.ini before flashing the ROM. Then just the proccess flashing step

I only found on russian forum information that S820_ROW_S220_140722 is problematic (no tested) to flash it on devices produced in 2014 http://lenovo-forums.ru/topic/7177-lenovo-s820-kitkat–прошивка-row-s220-для-пк-ота/page-12.
About the method you wrote is it "safe" – is it possible that i brick the phone by removing the cheksum.ini? Another question what is the preloader from your link? is it for this phone or some universal? BTW i would like to thank you for your support and advices.

Andy i have still problem. I changed preloader.bin and delete cheksum.ini and i tried flash s124 row in download mode and i have error 8038 which suggest that i should make firmware upgrade. However i can't do that bcause preload file i left empty. I also tried flash s221 row with rerplaced preoalder.bin file in download mode and i have PMT (Partition table or something like that) error. Maybe this phone NAND chip memory has wrong partition??

Andy, I finally flashed the phone with S820_ROW_S221_140730, with ur preloader in firmware upgrade. Phone started normally but the system works very laggy even after update OTA to S222 vers. I've reflashed it for S820_ROW_S124_140404 in download mode and with no errors ( like previously). System installed correctly but still works laggy. Do u have any idea whay is that happening? Is it possible that the phone is not compatibile with that roms? If there is no solution for that problem will I be able to change the rom for chine one according to ur tutorials?

Hi,For laggy i don't know about it because i need to see the phone an make analysis, sorry bad english. So laggy can be cause by device hard to find signal, see available memory from your apps on system setting, unstable ROM system and etc. So i must see your phone to know what it cause.I think it imposible if the ROM not compatible because this ROM is for Lenovo S820, yes maybe you cam try flashing china ROM and see the different, i think i have guide to install china, follow this http://bit.ly/1ulcuUQ, it will flashing china jelly bean… Read more »

Hi again Andy. First I would like to thank you for your guide's abaout lenovo s820. If you had not helped me, I would never flash any rom on my phone. Currently I have installed VIBEUI_V2.0_1443_ST_S820 and finally the phone is working properly, and most importantly, there is no lag. I do not know why is that and probably i will never knew what is the reason. Correct only VIBEUI_V2.0_1443_ST_S820 flash instruction. To eneter recovery mode you must pressing both volume buutons and power:) BTW you are great man!

Andy another problem have appeard. After flashing I've lost IMEI numbers and I have problem with NVRAM error. The IMEI numbers I was able to wrote back but I dont know how to fix the NVRAM error? Going further in this VIBEUI_V2.0_1443_ST_S820 is very weak GSM signal, the phone losses the signal without any reason (in places where the signal should be strong). Is there any chance to replace or upload new modem.img? Actually in etc/firmware/ ..

i bet you upgrade your device from system setting -> upgrade and got on build number Vibe UI 2.0 ?
VIbe ui 2.0 is china version firmware don't have google play so you must install international version or ROW. If your device is produce in 2014 please also download preloader or remove check list on bootloader and preloader

Hi Andy. I've just upgraded my Lenovo S820 bought in Saudi Arabia in 2013, trough the System Update, to KitKat 4.4. As soon as i did and it rebooted, after it asks me for my SIM's PIN's a message shows up saying Unfortunately the process com.android.phone has stopped. The SIM's can't be accessed and therefore the phone doesn't makes or gets any calls or messages, and the message loops every 3 seconds. If i turn on the Airplane mode, the message stops, and when i come out of the Airplane mode it doesn't shows up anymore but the SIM's still… Read more »

hi,
first try any other SIM card that not required any PIN,
your SIM card cannot be used because you not provide the right PIN, as far as i know it can be solve by come to SIM card provider and report about your problem.
but first maybe need check IMEI, dial *#06# and hope it not return invalid.
second try different SIM that not required PIN number.

Andy, the SIM and PIN both worked fine right up to the moment i did the updgrade for the KitKat operatistin system. Are you saying that just because of that update now the SIM is invalid and i need a new one?

Reply to  Filipe Eiras

Not the SIM that invalid, but the IMEI. Invalid IMEI will make your device can detect the SIM but you losing ability to communicated, but it just my guess. So to make sure please check IMEI with dial to *#06#.
So you mean you success input the SIM pin? If not so i guess invalid pin make your SIM blocked.

Well, took it to a store and they solved it for me.

When i brought it home, i noticed the time was wrong so i went to settings and pushed the automatic time zone detecting and as soon as i did that the message showed up again. I just turned it off and now everything is fine, so, it's clearly a bug, but for now a solved one.

Thanks anyway

Hello andy. I have an unoriginal version of lenovo (bought it half the price). I have seriously messed up the os before this and had to send it back to the shop. I didnt know what was the problem and the only thing i could think of is the preload and the preloader. Every mtk i downloaded is not the same as the one i have.

Hard bricking happen when you wrong flash ROM file and your device cannot turn on completely dead. But when soft bricking is device still can be turn on but then firmware stuck on boot.
