Try to explain better! Do you have installed custom recovery?

no i installed a modified multi language rom from "needroom" did every as told and everything looked fine during the upgrade and when i was finished i got the green circle that says it was ok but when started it up it went in to boot loop and said "TOOL DL image fail!" but after a while its totally dead.,when i try now it wont load in any software into the phone ,just starts up the purple pre preparation on the SP flash tool but when i connect the phone it stops .cant get it into recovery mode or anything,just completely dead. i would rely be thankful for some advice her

Maybe the package you've tried to install is corrupted.

most likely, but is there anything to do with it or is it over for it.

Most likely your device is unusable. Without any recovery, I dont think you will be able to do anything. I am sorry.

OK a 200$ experience richer , thanks anyway

method to install original rom android 4.4.2 in lenovo s850
i have found the perfact solution to install original 4.4.2 rom on lenovo s850...so for that you have to donload rom from the link in notepad file...i have uploaded notepad file and download link is in that it is about 1.1 gb...so it will take time to download and after that what you have to do is open flash tool and then check da dl check sum and then extract the file you have download of 4.4.2 android and then in flash tool click on scater loading and browse to the the extraction location and in extracted folder there will be a folder somethinf target bin in that folder select scatter loding file of lenovo s850 and then just simply click on upgrade firware and then switch off your phone and then wait to process complete untill green circle come...and if you dont have flash tool...google it and download...thanks i hope this helps someone...:good::good::good::good:

Hey h1dd3n_sn1p3r,
Thanks for your prompt reply. And the answers to your questions:
1) I haven't rooted my device yet. It was left with the stock Android Lollipop version offered by HTC
2) I did try the hard factory reset but in vain. Is there any other way to get it back on track?

i remove my simcards and sd card

If you are not rooted and dont have custom recovery just flash this OTA file
=>https://mega.nz/#!eI1iBCyR!8gIK9v-mIRUjtjemqXyfpX15ux24t8PLlNuPkXMiMd0
- - put the downloded ZIP file in SD card
- go to Bootlodder
- Click recovery
- In recovery Hold VOL UP 3 sec and press power once u will reach 3e recovery
- in 3e recovery < apply update from sd card >
-select the OTA file
-done

now my phone stuck again in a loop.
when i click recovery, factory reset, simlock, smartsd, it always restart..
how can i update my phone using OTA?
also, can i use OTA India region for Hongkong Region?
i never found any hongkong region official ROM...
my phone is just about 4-5 months only..

Mate its simple get lollipop twrp backup restore it! Do factory reset (wipe cache's) not system and reboot system .
When u will be in check usb debugging
If you want to stay stock relock boot lodder and flash stock recovery staying at boot lodder !
Thats all now u may go for OTA updates and your phone will be no longer rooted

I am not able to share screenshot, will this backup work for this version

Your phone in under the above mentioned title mode. One thing you can do is to reflash the bootloader and bring it back into flashable state.

Canvas A1 - Sprout 4 Hardbricked.SP Flashtool won't work.

My Canvas A1 isn't booting at all (nothing happens when power button is pressed),My phone has been unstable for quite some time now.Initially, I installed MIUI 8 and it crashed after one month or so.Then I installed Stock MM optimized version from XDA and it went well for sometime.Then after a month's period even stock OS crashed.Rebooted and stuck at bootloop.
After that I tried reinstalling the same OS but it always stuck at bootloop.
Hence,I went with SP Flashtool.Tried flashing (Download Only option) Official Lollipop FlashFile available here on XDA,it did flash successfully but phone wouldn't boot.
Next,tried All Format+Download option and again it flashed successfully but now nothing happens not even micromax logo shows up.Hence,I believe I have hard bricked my phone have tried every option that I could think of but to no avail.
I need expert advice on this hence posting it now.
Please Help.
Thanking in advance.
