[Q] Lenovo A850 Brick - Android Q&A, Help & Troubleshooting

Hi,
My phone cannot reboot and stuck in the lenovo logo. When i flash new rom using TWRP, before reboot it said my phone is not rooted and asking me to install or not install supersu. When i do both...the phone still got stuck into lenovo logo. i've tried many custom rom and restore it but still same problem. Can anyone assist me?

After flashing the ROM try to enter in recovery and do a data wipe/factory reset. In sammy mobiles that happened to me several times and i solved it that way. Maybe it works in Lenovo

[Q] Lewa Recovery flashed on Jiayu G3

Hello!
I have a problem with my Jiayu G3, I rooted it using Bin4ry's method, and used CWM to flash Android 4.1.2 , all was finished well, but whenever I tried to powe the phone , it always went into a boot loop. I read somewhere to try and flash Lewa Recovery using CWM, and now the G3 won't even boot into CWM and Android.
Any help is much appreciated. Thank you.

I think you will have to flash a new rom using mtk sp flash tool. You may have to try several versions before one works. Jiayu.es (in Spanish) should have all the files you need. Or, hopefully you made a backup and can just reflash cwm recovery and restore.

If you can access your recovery and/or sd card through mounting. Your device isn't bricked. I would suggest you double check everything you downloaded and make sure it's all compatible with your device. If one simple .zip doesn't match your device you can get a bootloop or soft brick (non-fatal) which is what you seem to be experiencing. Let me know if you have any questions and thanks for sharing!
Still facing issues..........

Bootloader accidently formatted

I have been encountering issues while trying to flash a custom recovery on my device. I have been using sp tools for this.
I accidently formatted the whole flash on my device and with it the bootloader also.
I have reflashed it with the stock rom I found on xda but now it is stuck in a bootloop. The lenovo icon is showing and then it just restarts again and again.
I am now unable to get it to recovery mode also.
Please help me with a solution.
My device is lenovo tab 3 7 essential
