What happens if you power it on while holding down the up and down buttons?

This just means you don't have a recovery.. just flash a new rom.
hi XDA community i have a problem regarding my a850 and i hope u or anybody can reply this comment in an instance cuz im in emergency...
IM EXPLAINING MY PROBLEM VERY DETAILED SO IT'S GONNA BE VERY LONG COMPOSITION, INCLUDING FROM IM ROOTING THE PHONE UNTIL I TYPED THIS COMPOSITION
so recently i "Framarooted" my device and was working properly as i expected,then i want to install TWRP, i see my baseband version does not have ROW or CN in there, it kinda like "A850.V13 ...(cant remember)", but i flashed anyway using the ROW version of TWRP and Mobileuncle MTK Tools. When I want to enter recovery (via MTK Tools) it doesnt show up, just stuck at white,big "Lenovo" logo (it probably doesnt work) but i was able to boot back to normal. Then i used System App Remover from Play and attempted to delete some chinese apps, and I DID a mistake... i was so clumsy enough to delete all chinese apps that origins from the rom i accidently deleted the file "classical" (which i guess the entire system ui, launcher etc) . Upon after deletion of that file I SHOULD HAVE NOT DELETE , it suddenly booted off with the startup sound muted halfway (its like, the boot startup sound have like 4 second duration and i heard the sound just for 1 sec).
Then it boots up again, but stuck at the logo "Lenovo For Those Who Do" after startup animation, so i assume this is bootloop or soft brick
Realising this incident i GOOGLED " a850 bootloop","a850 unbrick","a850 stock rom","a850 emergency reset" and "a850 emergency backup", then I found a website which describes how to flash stock rom to a850, so i did that, as it might work, but actually not for my case. I followed and downloaded exactly steps and files from that website and loaded Flashtool with its scatter file, then ticked PRELOAD and selected the preload.img, followed by checking USB mode ,clicking "Forced High Speed", checked the DA DL thingy, clicked Firmware Upgrade and the progress bar moved, after that i plugged my phone, without battery, to the pc via usb. I heard the hardware insert sound, but, Flashtool did not start flashing, it;'s still SEARCHING.
Then I read that u need the USB drivers, so I assume i do not have drivers for this phone. I used the Device Manager step and when I plug my phone, it pops up "MT65xx Preloader"(or MTK i dont remember) then I quickly rightclick and "Update Driver". It has two selections, ONLINE or BROWSE, so i clicked the online solution, but Windows seems cant find the driver i need,
so i used BROWSE option, which i used your usb driver by entering the directory of the driver in your file in "C:\Users\User\Downloads\Compressed\Lenovo_Drivers_SP_Flash_Tool_v3.1316.0.150\Drivers" clicked install then it pops up an error "The third party INF does not contain digital signature information", so it doesnt install. So I used USBDeview and plugged my phone again without battery, it pops up "MT65xx Preloaded" with a purple dot, and if you need, i rightclicked that purple dot and clicked PROPERTIES, and here's information it gave:
Device Name: MT65xx Preloader
Device Type: CDC Data

After checked, i resorted to HARD RESET via recovery (i tried to go to recovery again to see there's hope in there) and it BOOTED TO RECOVERY! (yay) but again problem strikes, the recovery I see now is FULLY CHINESE i dont understand even a single option i gave there.
So now my phone condition is still cant boot to launcher, and my very last resort is to use the JTAG option
pls help me u all and pls reply ASAP
thank you

You should log in to windows with out drivers verification in order to install the drivers. Tutorial on how to do than on windows 8 here. Then flashtool should regognize the phone... (you should fix this problem because you may also need it in the future)
There is also a way to fix your phone (if the classic theme is the problem) using ADB. Go to this page and scroll down to ADB method(tutorial) in order to install the classic.apk as a system apk through ADB.
(i am attaching you the apk: View attachment Theme_classic.apk)
Very thanks though cuz this actually solves my problem on my previous devices which doesn't detect upon connection, but I've actually resorted
to do unsoftbrick by a more professional person in my town (he sells and services phones) and it charged me RM50 ($15). Now my phone is back to normal with a rooted state (Chinese superuser app)
Again thanks for replying.
PS:also can somebody redirect me to lenovo a850 modding page? anybody

This is such a forum
Tried Installing a custom rom using Flashtool. Now the phone can't come and can't be dected by my pc. Installed the Drivers and they Installed. At first first I was having a Brom Error report Now nothing happens when I p,lug the phone.
Hey guys here is my issue:
Purchased a Verizon S6 that was flashed with CM 5.0.1. I need to restore to a stock rom and somewhere along the flash with ODIN something went wrong. The phone reset and now the phone starts up and goes to the Verizon green screen that mentions something about my system failing to start.
I can't access the recovery menu which includes the wipe cache option. I can access download mode and the Maintenance Boot mode.
Download Mode: When I try to connect it to the computer I get USB device not recognized. I have tried KIES i have tried smart switch. I have installed, uninstalled and reinstalled every USB driver. Device manager shows the phone as Unknown USB Device ( Device Descriptor Request Failed). I have tried 4 different Official Samsung cables and 3 non official. Girlfriends S6 is recognized instantly in download mode. Have tried 4 different machines. Windows 10, Windows 8, Windows 7.I have tried advice from many threads on here for 6 days now with no luck.
Maintenance Mode: Gives me options including wipe system. When I press any option the phone simply resets.
Can't access adb or fastboot, because the computer wont recognize it!
I have suspicions that this phone is " hard bricked ". I am without a phone at the moment and my job relies on it. I found a shop on the other side of the country that fixes hard bricks. I'm hoping this is still fixable via software, if you think you can fix this remotely please contact me! I am willing to pay $50.00 via paypal or square cash. I am on a windows 10 machine with an i7 and team viewer installed. Let me know if you are willing to give it a shot.
You might want to post in the Verizon s6 forum
I have a Coolpad F1 8297 (from Hong Kong) which is currently bricked. The problem is unique for me. Sometime back I had rooted my phone and installed custom Rom (something like ASOP don't remember exact name and probably it was for 8297w). The same was installed through TWRP recovery module. I am sorry but I must say that I was playing around with TWRP options and through mistake I deleted something and since that day my phone remained in boot-loop. I can only see the Chinese script & F1 displayed on the screen when I push the power button. I also cannot enter TWRP recovery. I tried to connect to the PC but even then it would not connect. I have installed all necessary drivers etc. Tried changing ports, cables and everything that I found on the net. When I attach the device to PC it connects and disconnects and this goes on endlessly. Please therefore help me getting a fix for my phone. Thanks.

Did you use this version?
https://c.mi.com/thread-3049986-1-1.html
Seems like corrupted /system or decryption issue. If you still need your personal data, dont flash or reinstalled anything yet. If you had unlock your bootloader, try booting up twrp and access your storage via mtp first.
Hello thank you for welcoming me following the screen breakage of my xiaomi I take out my huawai p40 lite 4g to troubleshoot which has actually broken down it actually reboots on the logo I can access the menus with volume + and power control for recovery etc to connect it via usb to the huawai software but the smartphone is locked I have tried everything for 2 days with adb etc but the adb software does not open under windows 10 I do not know what is the correct method
to reinstall the rom correctly I think this one is corrupted if someone is able to guide me
THANKS
