Hello everyone I'm new, I wanted to expose my problem.


after using SP Flash tool and done downloading and everything, I'm going to turn on the phone and the screen stays black I can not even get into the recovery (I tried to install TWRP)

how do I fix?

Please use SPFT again and flash previous ROM version.
Here is SPFT instruction but you need skip 6th step as you need overwrite all partitions

And here you have all available ROMs

If this method not work you need change SPFT option from firmware upgrade to format + download and after this you need restore your IMEI numbers . To do this please follow this instruction

Of course  you could have now hardware issue.

I presume you talking about umi max.
Firstly you need tell me why you decide to flash your phone, (did you replace some part or update phone before)

I updated it by a version of April 13th. From there, the device started to restart itself. So I found a site that showed how to get back to android 6.0. I did it through the FLASH TOOL program but then the device started to loop through. Without running!
Then I went back to rom 7.0 on April 13th through the FLASH TOOL program and I used the form "FORMAT ALL + DOWNLOAD".
Now the machine turns it on, it goes back off, it does everything except to stay stable ... it's a mess I can not make it stable.
Thanks for helping me!

If you have flashed now you should go to recovery or factory mode and wipe/clear cache, eMMC or factory reset.
To get to factory mode you need power off phone then press power and volume down until phone get to factory mode then use volume button to highlight eMMC and use home button to confirm.
Similar way is to get to recovery mode only you need press power and volume up.
If this doesn't help please use different ROM with SPFT and then follow factory or recovery mode.
Sometimes you need disconnect battery but this will void warranty.

Friend,
Thank you very much!!!
I'll try to do the procedure you indicated, especially that related to eMMC that I had not done yet. But I will try!
If not ask too much, since it has helped me a lot, how can I do to reinstall the IMEI number without doing ROOT?
Thanks again!!!! It's good week

To change or rewrite IMEI numbers without rooting you need use SN writer
