    1. hello andy,,,, can u provide the suitable twrp… i have tried that u share above… red and pmt occur… ithink i need to change the modem firmware because my signal get so low after flashing kitkat lenovo s820… but before chanfe modem i need twrp acccording to your tutorial..

  1. I had to change the scatterfile, replaced it with the one that I had downloaded for flashing 820 S124 (that work fine). If you studie the errorlog from SP tool you come to this idea, then it worked fine but took me 2 hours for this idea.

  2. I am almost totally happy with this article. Spend hours on this subject, partially I reached my goal, thanks! Lenovo s820 4.4.2 TW ok install, ok but AFTER a reboot I loose all Root possiblities (root checker and so on). Main target was to have Lind2SD app use the second ext2 partion on my 32 GB SSD, this worked and I was able to use unlimited Apps from the store, SUPER now i can use my phone after almost a year! BUT after a reboot this is gone, luckyly all linked app to sdd keep working because they already in this system symbolic link system, but new links are not possible. Workaround install again and you have another session root until the next reboot. I can live with that but I am curious why? Also why can de king user app not gain root access (it says). Do you have a hint here?

    1. hi jan, i am happy too. so you mean after reboot you lose your root ability ?
      i never hear about losing root after reboot, but there is an option to un root and install standard recovery after you successful install custom recovery. this linux script store and name /system/etc/ after you success install custom recovery and reboot you will ask if you want to un-root and want to back to standard recovery ? if you select yes this script will be run and your losing root and custom recovery

    2. hi jan,
      i don't ask you to unroot it, i just say after flashing twrp there will be an option that can lose your root ability, maybe you accident click on that button. but i think it impossible even you factory reset the root it still there. once you install su binary it will stay there until you re-flash your system partition. But if for make sure i will search it on net, why this is happen

  3. I had installed previous trwp version on my lenovo s820 4G stock. It wasnt helpful as it could not mount sdcard and I was unable to root system.

    Now on trying to install this new version it says PMT Changed for ROM; It must be downloaded.

    Can you thus provide the recovery for 4G version as well

    1. hi,
      PMT change sometime because the ROM is not suitable for the recovery of file that you wanna flash with Flash Tool, This for KITKAT ROW, are you sure you use ROM firmware? please make sure it first or please give me your Build Number from about phone section.
      thank you

    2. hey raj,
      please use scatter_android file from S124 ROM, as you said that you flash rom back from S124 and then updated to S220. don;t use scatter file from the TWRP download but use scatter file from S124 ROM download. try it

    1. Yes, it will appear just 2 seconds than disappear before it disappear right click on it and select update driver, point to usb vcom extracted folder. If you like you can use newest flash tool but i don't recommend it and if it result error than enjoy that error. What is your problem anyway? You just send screenshot that i cannot see and complain about everything, just tell me and if i can help i will help it.

    2. Hey thanks fr replying.. I thought i wudnt get a reply today…

      I have installed it via the "Updatedriver" and it has installed properly, but even after that, I try connecting the USB back in , i can see the device manager show the port, and even "Download" in SP Flashtool starts at red. BUT then the driver isnt detected…

      I have tried showing Hidden devices, the only result I found is that it works for like 3 sec.. then it doesnt get detected at al.. Only if i plugout n in it ges detected 🙁

      PS: I was scared i bricked the device, but thankfully i didnt brick it 😀

    3. From what you say and describe, look like not flash tool error or usb vcom error. Look like your usb port got detect and not detect problem, or maybe your driver need to reinstall or maybe your windows. So maybe you need to check usb cable, try different usb port or maybe you can try different computer. And i think don't press download button first until you solve the connection problem, we don't wanna on 50% then your device not detected, it will brick your phone

  4. I also have problem with flashing TWRP,
    i want to try the method to use s820 s124 scatter file instead of using the TWRP scatter file, but, i don't know how, i have download the unproblem TWRP, but also cannot flash it,
    when i connect the usb, it show two port, when i dont hold any button, it show port7 and when i hold it show port 9, so could you help me senpai, 🙂

  5. Andy I'm on stock recovery and i want to install the custom recovery. I had tried and has already run the process Custom Recovery TWRP v2.7.1.1 for Lenovo S820 Android Kit Kat ROW Version. The problem is when i press power and vol up+down it goes into stock recovery again..?
    Need help dude 🙁

  6. Hi am using lenovo s820 8gb row s223_150119. Am getting 8038 error. I have seen the previous comments but i am not able to download the file. I dont know whether i have to change the scatter file while flashing. Please help. thanks

  7. Thank u so much Andy.
    After a long time i got my S820 Row back with root permission and With IMEI also.
    I just Flash my s820 with ROW S124 Rom and than update it via OTA and than root it with ur guide. i used scatter file of S124 Row firmware to install Recovery in KITKAT and i Success.
    Thanks By Heart….

  8. hey andy I've installed S820_S221 firmware, and I haven't root or install any TWRP or CWM. How can I get the OTA update for S820_S222, I tried over the system update, it downloaded over wifi and reboot but after says failed to install. I wonder what is the problem, Can you help ?

  9. my s860 dosent have SD card slot. so how I install custom rom? I have downloaded the .zip
    If I put it on the internal storage the twrp cannot find it, it only shows SD card, but I cannot find the sd card folder anywhere.

    1. nope, still cannot find it, when I reboot into recovery it deletdes the .zip
      twrp says internal storage (0mb)
      also it says cannot mount /data, /system etc, also says I dont have OS or root but I have.

    2. yes I can see all my root files and android stuff with root explorer in /root/ directory. everything works fine, but twrp is somehow bugged, how can I mount it?
      I have tried many dirffrent versions of twrp and tried flashing stock rom again and stuff.

    3. Lenovo S820 right ?
      then i guess there is something wrong with your partition, so maybe the solution is re flashing it. but if you want try to root it try using one click root method like kingroot, kingo, vroot and etc just search on the net

    4. s860 it is, but everywhere everything says it same as s620. I have triewd all diffrent recoverys for s860 and they wont work.
      I have rooted my phone, I have flashed stock rom many times, flashed many many times recovery again. still nothing
