I warmly welcome LG H440N phone - apparently it was updated some time ago android. Unfortunately, I don't know what version it is for. Allegedly the phone worked and after 2 weeks of bedding in the drawer it stopped ... During startup at the start of the message:
I also have such fears. Amazingly, the warranty has recently expired .... Once I managed to enter it in the download mode state and after the manufacturer's software I downloaded and installed soft, but with no result.
Even if you connect the phone to the charger to the network, it does not charge, and restarts over and over again with the same message.
I am considering the eMMC service for me. How are Samsung and certs? other models can do it too? there is no problem in soldering, neither is soft handling. I never wanted to do it, except for old HTC and Samsung on the first riff.
Worth it for yourself and your phones. For the customer already differently. I recently made several pcs desire 820 new bones and exit. Cash register returns but slowly. Well and still data recovery means better money. Everything goes to embrace qcn certificates.
It's nice that the experts said, but ... what and where to buy such memories? And what software and how to upload? My son's phone broke down and the PC can't see him, so I can't download the software via USB.
Bones available from Chinese or sometimes Allegro - about PLN 50 Programmer with adapters - ~ 1000-1500 PLN. Hotair - for stubborn ~ 500+ flesh type bullshit, etc. To do this would be to train on corpses desoldering or removing old bones so as not to damage the soldering fields underneath (eMMC are often flooded with various shit that makes work difficult) and something to upload the software , calibrate and fix IMEI - equipment costs are also ~ PLN 800, but some "free" solutions can be used.
In some cases, you can do without a programmer if after soldering a new bone the phone displays some interesting interface, 9006 (eMMC storage) or 9008 if there are publicly available loaders and soft, or if you can use a memory card from which you can boot the bootloader.
Either way, for the repair of one device unprofitable and in general, for this model at all unprofitable. Plus, if your PC _ doesn't detect anything at all and your phone doesn't fire at all, the problem will be somewhere else.
You could suggest looking for a donor for a penny, for example with a broken LCD, but you must be aware that the falling eMMC is a common problem so probably for some time and so it will happen.
I put BGA gentlemen and I can see how it is done, I even have a microscope, but ... I don't think it's worth getting tired. At the moment the logo is displayed and in the upper corner you can see the changing inscription error code number and boot verification fail cause different hash unfortunately the phone neither reports under Linux nor sees it windows
Since you already have a smile on your face after this amusement, buy the devices that a colleague wrote about and do it yourself. Or look for a local Janusz who has several programmers at home and you can make two beers together. I close the topic because further writing or questions do not make any sense.
