You can contact RCA support to get more information about the return and warranty policy if you are unable to return the tablet to the retailer you purchased it from. They may require some form of proof of purchase as well, so I would try to find it before you call them.

I had an similar battery issue when I owned a Motorola Defy and I used a tutorial I found on XDA Developers to charge my battery. I would expect similar results to help charge your battery. If the bootloop is a result of the battery being low, then this may help, but if the bootloop problem remains, there may be something else going on. Hopefully, this does work for the battery.

If you want to do a factory reset of the Dopo M975, ifixit has instructions. View the question, Why does my tablet keep freezing? This will erase any data on your tablet. I also found a tutorial on youtube that shows how to change the language to English, that may help you. You could view other videos with similar titles that might be closer to what you're looking for as well. Lastly, page 19 of the manual has a screenshot of the English menus that you could use the respective icons to Navigate to the language menu that can help complement the video I referenced.

I performed a search on Youtube for relevant videos for the outer glass. Most results showed the replacement of the full LCD assembly. I cross referenced the release date of the E7 with the S6, which showed they were released two months apart. If the manufacturing process is similar then the procedure/technique should be consistent for both phones. I did find the Front Outer Lens Glass Screen on Amazon, so I ran the search on Youtube for the S6 instead. I reviewed, Samsung Galaxy S6 Disassembly - Glass Removal - Glass Only Replacement, which should be similar for the E7. Additionally, I thought, Galaxy S4 JUST THE GLASS Screen Repair BEST Video was also helpful, though it is for the S4, which was released two years earlier than the S6 and E7. The technique and correct tools used is what makes the removal process successful. With the availability of the part to change the glass, it should be possible, but please take into consideration that since there is limited documentation, the possibility of the...

Replacing the broken back of the phone will require that you have tools to remove the back as outlined in the Samsung Galaxy S7 Edge Teardown. I also found, How to Disassemble/Teardown Galaxy S7 Edge for Screen, Battery, Charging Port Replacement on Youtube. Alternatively, you could also attach a case if the removal process is not possible and/or the damage is not too great.

I did not find any documentation on their site, but upon doing a Google search I believe I have found the manual. I reviewed the specifications page on page 1-2 of the manual against the product page and they are similar. A comparison of the images for both, also show ports and connections that are similar. I'm not sure if you are trying to replace the SSD or the SATA Hard Drive, but the manual has instructions for both. Thank you for the post and good luck with your replacement!

You can view Bluetooth on your device on the Beats by Dre site to get instructions for your Android or Apple device. You can choose your specific device, which list instructions on syncing the headset after your phone has bluetooth enabled.

From your description, the LCD is cracked. The outer glass you described is the touch screen digitizer and it sounds as though this is intact. If it was broken, even with the LCD visibly cracked, you would see that it was also broken. A similar question was asked in the forum titled, How do I replace a cracked screen? In reviewing that post, the first answer indicates that the digitizer can be replaced independently from the LCD. Upon doing a search on Amazon for the LCD itself, I did find one listing that you could use to purchase it separately. However, the disassembly video in that post was focused on replacing the digitizer. I found a similar video on Youtube, titled RCA 10" Screen Replacment - Disassembly - RCT6203W46 PRO, which may be more relevant to start from the back and work your way to the LCD. This video goes as far as replacing the digitizer, but you'll just need to remove the LCD and the respective connections and attach the appropriate ones to the new LCD. Furthermore, I did a search on...

There are many generic dual-sim phones that can be found that are unlocked from the factory. I would recommend going into the settings for the phone and doing a web search on the model information that pulls up. While the bands you indicated work well for cellular service, they may only provide you with G or 2G for mobile data and not 3G/4G. In some cases, the APN settings for the phone may need to be manually configured for your provider to support cellular/mobile data. It sounds like you've indicated that no provider information displays when you have a sim inserted. If the calls work, but mobile data does not, then you'll need to contact the provider. If neither work due to the phone being network locked, usually the phone asks you for an unlock pin when an incompatible sim is put in that is from a different network.

Removing the case is documented in the [Magellan RoadMate 1200 | User Guides} pages on this site. If you suspect that the connector has been detached, then it may need to be re-soldered to the logic board.
