Re: PREAMBLE FOR LENOVO A1000 ROM RECOVERY ETC

Hello.

I've been reading this whole thread and it's pretty useful . I have a tablet Lenovo A1000 -F , which failed one day ago and I would like a little help (it´s a new tablet, 7 days of purchased) . Something like that's the case:

  1. Root Android with Kingo ROOT , and everything worked fine.
  2. Edit the file " build.prop " in the system path . I have a copy of the original in the internal memory of the tablet.
  3. I rebooted and froze on the brand name .
  4. I tried turning off and turning on again , the button next to the MicroSD , recovery menu ( if I remember correctly ) Wipe Data Factory Reset & Wipe Cache : nothing works.
  5. I used this file to Flash tool "A1000T_TWRP_v2.5.0.0" ( recovery.img ) did not work.
  6. Fixtool I used did not work. All trying to access the internal memory to restore the "build.prop" file
  7. Then accidentally use " Format whole flash except bootloader " option and the only tablet vibrates when turning but no longer turns the screen, not the Recovery mode starts the logo " loading " or appears .
  8. I repeat , vibrates at power on, the PC recognizes it as a removable media (but not allowed to view the storage).
  9. I have a backup I got in line, of 377 Mb with the name " TWRP - Lenovo_A1000_MT8317 " but not how to use it. Also downloaded the Android SDK Manager " and do not know which way to use it.
  10. The operating system of my PC is Windows so Linux solutions are inapplicable me.


I thank you in advance for your help.

P.D : I hope not violate any rules of the forum.  Smiley Very Happy

Re: PREAMBLE FOR LENOVO A1000 ROM RECOVERY ETC

from ur message i got one thing that u dont know there are two devices with different names , one is a1000f and other is a1000t or a1000g, first get a clarity regarding it
if ur tablet is a1000f u made a mistake by flashing a1000t twrp
flash a1000f twrp( there are two twrp s so dowload a1000f twrp) from message 4 , strictly follow the steps while installing , after installing for the first time u strictly need to go to twrp by pressing volume key along with power key
now restart ur tablet by pressing power button and volume up key restore the back up
u also mentioned that u got a back up , restore if and only if it is the back up of ur tablet tat means same model

u also mentioned that u formated everything ,first check whether u formated all blocks or not , to know this follow message 3 of extracting rom ,do to step 5 , see whether all block consists or not

if they are missing any block go to service centre and tell them to reflash the full rom

Re: PREAMBLE FOR LENOVO A1000 ROM RECOVERY ETC

When you edit build.prop file and save it after that you have to change permissions back to rw-r-r, otherwise you would get stuck at boot logo.
There is a stock rom file at ru forums (lenovo-forums.ru) for your a1000f tablet, get it and flash it.
If your pc recognize your tablet (even if as a media device) then your tab's preloader(bootloader) is not formatted and you can safely and worry free flash the stock rom after reading all info. from the forum about how to flash. (If you don't know russian then you can use google translate).

I think you don't know flashing procedure.
When everything is setup including dtivers properly working and sp flash tools, then load the recovery.img into sp flash tools using scatter file and then just before pressing 'download', remove your tab from pc (if connected) and press download and then rapidly connect your tab to pc, it will start flashing.

Re: PREAMBLE FOR LENOVO A1000 ROM RECOVERY ETC

Thank you very much, give me hope. I going to Seek the Stock ROM that mention me and I'll read about the flash process, I will notify you about the progress.

Thanks for the tip Balas, but I have no PC with Linux to do what described in the message 3. I will read the rest.

For now, the tablet breaks into Factory Mode (On + Volume down), I hope it's a good sign.
