[Android Head-Units] smilefish:
Hi there,

I own the same device YH605b slim version since last summer (after a challenging order.... So - on BG site, the product was in stock with mention of quick shipping... bout 5-7 working days from UK warehouse or other Europe country... after more than 2 weeks the status of the order was still "pending".... ticket open, mail/chat etc... i had to cancel the order as they told me the product is not in stock.... about 7USD loss due to conversion fees.... then a new order places few days later when the stock became "enough". the history repeats with the same delay and lot of time in pending. Sick of their stupid replies asking for more and more patience and finally i just let it be the way they want.... didn't consider another refund, just accepting to wait another days.... finally the item arrived in about 3 weeks later)

The product itself is cute... but just that! Even if the memory is 4GB, the processor is so slow that any installation takes minutes.... even for simple apps.... which is a pain. The touch display is not well calibrated (at least in my case there is an offset of almost 1cm... so i have to touch with 7-8mm to the right than the button of volume, for example... The size also is weird... typically to most of chinese cheap things, there are no standards....

So far.... i got used with these downsides. But... after about 5 months i just noticed there were some issues with my google account which was logged in since the beginning. So i had the "bad" idea to remove it, in order to add it again... here it comes the frustration... each time i reach the Google login menu, just after i touch the username field, the page returns to the previous screen. I tried everything possible. Reset the whole unit, trying to get to the authentication from various screens/menus (google play, youtube, add account).... the same behaviour. Thought it might be related to the virtual keyboard - so i had to install (apkmirror and external apks, as Google play was impossible to authenticate in) GBoard and other Keyboards... no luck.

I had to argue with BG support for that issue... after about 3 weeks of stupid requests, explanations, step-by-step actions on my side, then video record of the issue they accepted there is a software problem. Eventually offered my BG points as compensation, as the product was not in warranty period (only 6 months since receiving)... i continue to argue and ask for a real compensation which roughly increased from 10 to 20, then to 30 USD. As none of their "offers" couldn't fix one of the biggest problem - for example not being able to enjoy my YT / YT music playlist from my premium account due to impossible google account authentication, i tried my luck based on either win my way or lose everything but not their 30 bucks... so i gave them the ultimatum - 50 bucks and i consider to remain their customer or nothing - but also no more orders and bad advertise for their low-quality products and services.... and after 1 more week, they accepted my final proposal.

I haven't though many hopes to find a solution in my case... so i just remained with apkmirror and some apps that don't require an authenticated google account (good bye YT, maps, etc). Thankfully i have Waze and Sygic for navigation, TuneIn and Spotify for music.

Then i was looking for a way to connect an 8" tablet output (headphone jack) to the Aux input of the Yuehoo.... but the amp is a joke... i have to increase the YH volume to the max (also for the tablet) to be able to hear the sound.... well... another disappointment...

However, in my search on the internet i think i was lucky enough to find this thread and your way to root the device.... here i am, after i tried (and succeeded) to install the image you have shared here. The device seems to be rooted, but, unfortunately i still cannot authenticate in Google account.... i really hoped the re-installation would repair the problem i have... but it seems i'll bear with the other apps without YT and Google Play suite.

By chance, do you might know what else can i try before i drop the unit right to trash? I consider the investment a big loss... not in money, but in time, anger, stress, annoying and frustration.
