my BV9500 suddenly stopped working. Reset to factory does not help, the system is not loaded. I / o error messages appear during reset. Need to replace the nand flash. How do I? Ask for help.

Hi there, unfortunately you'll have to contact your seller to have the phone replaced under warranty.
The seller is the only one who manages warranty terms, repairs or replacements.

I have contacted the seller many times. His answer is to reboot the smartphone in the recovery mode and everything will be fine. But it's not. I've done this 6 times. The problem is in NAND Flash, it is indicated in the log file of the recovery. The seller has a video and photo from the log file. The seller does not answer me for 3 days. I'm asking for Your help. How do I?

Unfortunately your seller doesn't seem to be a professional one. I'm really sorry for that but i can't do anything more to help you with that. 
If you bought the phone from Aliexpress, you can open a dispute to try to get your money back.
If you paid with paypal,  you can open a dispute to get the money back aswell.

I understand that not all managers are technically competent...I was hoping he'd go to the experts with my video and photos. I didn't open a dispute. I didn't want to hurt the reputation of the seller and Your company. Now the buyer's protection is over. It would be a shame if he didn't answer... That would be dishonorable. The store is called Blackview official store. So I turned to this forum.

I had a communication with Blackview Sophia before.  I tried for days, weeks, I forget how long...  back and forth, one e-mail a day, because I type while they sleep and they type while I sleep (opposite sides of the world, of course).  The problem I was complaining about is a technical one, which I'm 100% certain can be solved in software.  Unfortunately, 156.73 percent of people reached through "support" channels are little more than warm-body note-takers who just forward the note on to technicians and engineers -----  **IF** they deem the note worthy.  But when they don't understand the problem, well, it goes nowhere.

In my case, the people answering the "sophia" e-mail account did not understand my issues.  They have ZERO clue about the two-way radio feature, and I'm convinced they thought my problem was that the people on the other end of the radio communication couldn't hear me because I used a different send and receive frequency (which is what you have to do with repeaters and is, in fact, why you can do different send and receive frequencies).  They were convinced that was my problem and every reply they sent me after that was "please make sure the send and receive frequency the same".  I even spent a couple hours using Google Translate in both directions to try to ease the language difficulties but that seemed to do nothing.  Maybe it even offended them, I have no idea.  I was just trying to be helpful.

I even gave them a video, showing that the problem had nothing at all to do with frequencies I use, but rather had to do with the fact that eventually, if you add one too many "Device Area" groups, your radio locks up and won't initialize and the only way to fix it is to delete app data (and all your hard work entering frequencies to use).

They couldn't (or wouldn't) understand.


I also had a question about the CTCSS tones, but they have Z-E-R-0 clue about what that even is and couldn't understand anything about what I was asking, and even asked me why I wanted to know the information.....


uhhhhh....  because repeater CTCSS tones are audio frequencies like "67.0 Hz" and "127.3 Hz", not numbers like "1", "20", etc. and I had no way of knowing what table I find online would match, perhaps?  But they're not technical.  They can't understand.


Anyway


Yeah, Blackview's after-sale support, while it appears they try, I find lacking in quality.  The language barrier I think is a big part of the problem (or, they're hiding behind it to avoid tough fixes perhaps, I don't know).  Blackview_Admin here at least seems to have a decent grasp of English, enough for effective communication.  The people answering the blackview.hk e-mail addresses, on the other hand, again while they try, they just fall short.

This is just my experience.  Someone speaking fluent Chinese might have a better time getting the idea across, but alas, I do not.

Please limit going off topic! Thanks.

I apologise, Admin. I saw the remark by the other participant about technical competence and that was what I had in mind with my reply. I realize now the mistake. Sorry about that.

Nice to know that in this forum there are good technicians. Tech Addict, thank you for useful information.

can anyone tell me about emmc? where it is soldered on the motherboard (so as not to remove all shielding protection) ? I want to see the serial number of the flash chip and try to warm up the chip to 200 C. Если у меня получится запустить систему то мы узнаем кто и когда сделал нарушение технологического процесса при производстве motherboard.
