Yes, you can use the Win 10 Drivers from here:

http://laurentiumihet.ro/technology/windows-10-mtk-vcom-usb-drivers-for-32-64-bit-drivers-installation-tutorial/

You don't have to let the battery run out, just make sure it is off, but I suppose if the battery is really dead, it is hard to tell. Hopefully applying power via the usb cable won't turn the thing on. You can only run the preloader and SPFT if the tablet is off.

Follow the instructions from that web link on how to disable driver signing. For some reason on Win 10 you may or may not get the red lettered warning on installing unsigned drivers if you install more than one driver. Make sure you install the Vcom Preloader, that's all you need.

The best full sized bluetooth keyboard is a Logitech K480. In the U.S. you can get a refurb from Newegg for $20-25, or new from Amazon for $29 if you have Prime.

Well, in Canada it is more expensive: http://www.newegg.ca/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=logitech+k480&N=-1&isNodeId=1

Goodness, everything in Canada looks a bit more expensive.

If you want smaller, get the Logitech K380

With shipping and taxes, CAD 49.45 (about USD 37.08). But that's commonplace... My tablet was CAD291 with taxes ON SPECIAL (normal price was CAD329 at the time (+15% taxes or 378 or USD283) :rolleyes: It's cheaper now, only CAD280.

Nice! But I can tell you one thing: I never typed so well as on my old Casio Electronic Organizer with its button-type keys. Hardly made any typos with that keyboard...

Charlestek...thanks for posting all that info. I have the Win10 Vcom drivers loaded as per the info on that link. Got rid of the defunct SPFT that's now old, but can't download that new SPFT until I get down to my local Best Buys to hop on their WiFi. Virgin Mobile has data capped me for the month. UGHH! At least I saw that old SPFT trying to feed the scatter, and boot.IMG to Com port8. Problem is the tablet is on port 7. I tried the uninstall trick but it didn't work. I'll load the new tool tomorrow and also try to update/check the Java version on my PC. I can now feel some vibration from it like it's trying to spool up. I've managed more results in the last few posts than I've managed in 5 months! MTK devices are very new to me. I thank you for your knowledge! I have new hope and can, if this works, get my hubby of 35+ years off my back about the purchase! Woo Hoo!

Not able to flash stock firmware

Hi all,

I have a Lenovo TAB2 A10-70F and unfortunately I cannot flash the stock firmware using SP Flash Tools. Here you have the long story in a short version.

My tablet updated to Lollipop 5.0.1. I rooted the tablet using Kingroot, which was successful then I replaced the the Kingroot with SuperSu using the SuperSU Me app from the Google Play. After the installation the tablet required a reboot. And then my tablet wouldn't boot anymore. It stays at the logo screen forever. I've managed to go into recovery, did a data and cache wipe, but nothing happened. Fast boot is not working as well.

After reading a lot of tutorials I proceeded to flash a KitKat Rom. Downloaded the stock rom, SP Flash Tools, USB drivers and followed the steps as described in tutorials.

SP Flash Tools seems to work OK, but the flashing process stops after the red progress bar reaches 100%. After that nothing happens. I use Windows 8.1 and the latest USB drivers.

If you guys have any idea about what is going on please let me know. I love this tablet and I don't wanna see it thrown away in the garbage.

Thanks for your time and sorry if this is a double post or it's been answered somewhere else.

Keyboards

Old Faithful... Got an idea about the search for a keyboard....

Go down to your nearest Best Buys, Staples, or other "big box" tech retailer with your tablet. Tell the sales staff your searching for "The Ultimate Keyboard". Look at a few, ask questions, maybe hook a few up & take them for a test drive! See what works for you & your baby. Then comparison shop for prices on line. I really liked the keyboard Microsoft came out with to go with their Windows tablets & the Surface Pro series. They come in colors, they will Bluetooth connect to an Android, and they aren't bulky. They were a bit pricey when I was shopping because they were new on the market which is why I had to pass. That was about the time the RCA crashed, bought the Tab2, screen protector & case to replace, and my hubby was traumatized at the bill in the end! (Which is why I have try to get that RCA running!)

Every keyboarder has different needs. Good luck!

Win 8 (not sure about 8.1) drivers are here: http://laurentiumihet.ro/download/mtk-drivers-32-64-bit-xp-vista-win7-win8-zip/

Which partition did the flashing stop at?

Was there any chance that plugging in the usb cable accidentally booted the tablet (well, I know it doesn't really boot)? That would stop the flash.

Also, I'm guessing that the red progress bar is the DA transferring to the tablet. Are you sure the path to the DA*.bin is set correctly in SPFT?

Are you sure you have the Vcom Preloader driver functioning?

In windows systems variables, enter a new variable: DEVMGR_SHOW_NONPRESENT_DEVICES, value = 1, and then in device manager check "show hidden devices"

You probably have either a ghosted Vcom preloader or a Vcom preloader with a yellow thing on it...??

You don't need Java for SPFT (plus it is a security risk for windows, I uninstall Java from all my Windows machines).

The latest SPFT is here: https://androidmtk.com/smart-phone-flash-tool

I'm sorry to hear that you don't have WiFi at home, am used to taking that for granted. I hope you can get your download. Surely there are other places for free WiFi then

Best Buy...., if you sit there, they might try to sell you something else....
[Android General] nannycrick:
charlestek...I'm not worried about those youngsters down at Best Buys selling me anything. I actually hauled my HP 27" AIO PC down there to do the Win10 upgrade. Took hours on the AMD system! (Intel is SO much better!) While I was there waiting for the upgrade to finish, I managed to help a few other old folks like me! Old folks take advice better from other old folks. Most of the time, I just nod my head in agreement with the geeks, and they leave me be! LOL!

I'm a retired C++ network tech, and androids are a new hobby! MTK devices are very new for me. I like HTCs, anything Dell, and some Linux. I run Java in my stuff cause It's the common language between Android & Windows...and I'm old school...cause I'm old! LOL! I'm also on retirement income so money is tight! Hence the limited connection.

I may be old, but I appreciate "youngsters" who choose to be knowledgeable! I believe I have a good chance of restarting that RCA now! Thanks tons for sending me in a good direction!

And high speed WiFi is free...at my son's house. But by the time I'm done watching the grandkids, I have no strength for firing up the devices!

(Remember..my name is nannycrick for a reason!)
[Android General] charlestek:
Well, if you babysit the grandkids, tell your son to pay for wifi at your house, or else he can cope with them running wild all the time.

I used to be a C# Microsoft .Net developer, but gave that up 5 years ago. I never touched Android until this past month. According to Tzul in the Lenovo forums, Java is only used somewhat for the GUI in Android. You could develop Android in C# with Xamarin, though Microsoft just bought the company: http://xamarin.com/download-it?_bt=101035044668&_bk=xamarin&_bm=e&gclid=CPXz3LjZwcsCFcUdgQodvf4CDA

WHAT IS THE EXACT MODEL OF THIS DEVICE. DOES THE RCA DOWNLOAD PAGE HAVE FIRMWARE FOR THIS? IF THE MODEL IN THE XDA THREAD BELOW IS CORRECT, MAYBE TRY THE FILES IN THAT THREAD

RCA RCT6203W46 1.9.50 firmware upgrade failures

Below is the method I found to resolve the issue I had with the most recent firmware upgrade failing. Use at your own risk.

How to resolve RCA RCT6203W46 1.9.50 firmware upgrade failures (this should also unbrick your device provided you can access stock recovery):

1. Place these 1.3.51 and 1.9.50 update zip files on your external sdcard. If you can only boot into recovery, you will need to eject the sdcard and use an alternative method to transfer these files from your PC to the sdcard and then place the card back into your tablet.

2. Boot into stock recovery. You can do this from a powered off state by simultaneously depressing the power and volume buttons until the white RCA boot screen appears. Once this screen appears, release the power button but REMAIN DEPRESSING THE VOLUME BUTTON until you are in recovery.

3. Select: Wipe cache partition. (use the volume button to move selection up or down, press the power button to make selection)

*Factory reset wipes cache too in step 4, but I am cautious.

4. Select: Wipe data/factory reset. Warning: you will lose any app you had installed.

5. Select: apply update from sdcard. Select the 1.3.51 zip file. Allow it to complete.

6. Select: apply update from sdcard. Select the 1.9.50 zip file. Allow it to complete.

7. Select: reboot system now.

8. Enjoy your upgraded RCA RCT6203W46 once again!

Probable causes for issue:

Rooted system (forgot to unroot prior to upgrade)

Removed or froze any stock app (including Vudu, Walmart, etc)

Modified a system file (build.prop, etc)

Bad luck
[Android General] nannycrick:
My backups were from my tablet BEFORE I sent it back after it crashed running an rca update. The tablet I got back must not have been my original tablet! That's why my backups don't work. (Error codes 4032 & 5054!). No original firmware available from rca..of course! I downloaded Droidify's firmware but both are only partial ROMs. They didn't work either. It's going on Craigslist as PARTS. Has a good, unscratched screen!

I appreciate all the help. I learned the value of having ALL stock firmware stored away for my MTK devices.

I'm sorry for distracting my forum mates from the goal of this forum...to continue development of of Tab2...which is now a Really Great machine! Thanks guys!
[Android General] charlestek:
No need to apologize. That is what the forum is for. At some point we might split this discussion off to an RCA thread, but at the moment, we're on this thread.

IF YOU MADE YOUR OWN BACKUP, WHERE DID YOU GET THE SCATTER FILE?

Otherwise, it sounds like you may have made the backup with another tool, what was the tool?

If the backup was made with another tool, there is no guarantee the format of the backup is something SPFT can use, and SPFT needs the hex addresses of the partitions from its scatter file to flash the memory.

Please stick to answering the questions. Please Read the label on the RCA and specify the model. I don't know how you are coming to wild conclusions that you received a different model, there must be an id sticker on the device.

There are firmwares apparently available by googling, BUT WE NEED THE EXACT MODEL YOU HAVE. PLEASE TURN THE TABLET OVER AND FIND THE MODEL INFO AND REPORT IT.

Rca downloads here: https://rcasupport.zendesk.com/hc/en-us/categories/200317055-Tablets and https://rcasupport.zendesk.com/hc/en-us/categories/200317055-Tablets

I do agree, that is simpler to sell the tablet for parts since you have the Tab 2, but for the purposes of making the previous effort to restore the tablet fruitful,

I feel that you should spend more time explaining all the details of exactly what you did and with what tools. It is hard enough to get to know using SPFT, without knowing the full history of what went on.
[Android General] nannycrick:
Those links have no support ware for the rct6203w46. I downloaded the two from the Droidify post but those are only partials, and their scatters won't load. I have pics of my rct files. You'll see the Droidify zips...1.3.51 & 1.9.50 unzipped w/7zip. The rest of the files were from my backup of my original tablet saved to my SD card. Second pic is the build prop from the original.

[Android General] nannycrick:
MTK Droid Tools is what I used to make the original scatter file & backups courtesy of Gigabyte's post. I used that tool to make one for the Tab2 when I got it. I'm downloading those zips from page2 and will compare them. In my first pic you'll see the naming of the orig scatter. The text of that build prop is correct for the device. I'll keep in touch. I hope to be posting a pic of a running tablet. I've been rooted since six months after my first android..LG Optimus V came out thanks to the great Jerry Script and his IHO rom! Been rooted ever since!
[Android General] charlestek:
Read my revised post #550. As far as I know, the flash files and procedures with MTK Droid Tools are completely different from SPFT.

Need to find an expert on this forum to advise, but read the RCN thread for your model in post #550 previous to this post.
[Android General] nannycrick:
Got that! I used that tool cause it was the first thing I loaded when I got the RCA. I was a new MTK owner. Knew absolutely nothing about them. I didn't learn about the SPFT until it was bricked. I got desperate !

Update...got those Droidify files newly downloaded from page2 of that forum. Scatter files of both zips will not load...Error_8417 the load scatter file is invalid. Only the MT8127_scatter files I had from my backup will load without error. Directory path is good...Desktop.

And yes, I know this question is coming...I keep the files for the Tab2 & the Pro II labeled separately so I haven't got them mixed. I'm only working from one set of files...I don't want to corrupt my Tab2 files I have in reserve!

Still working thru what I learned. Thanks for the good advice.
[Android General] charlestek:
Yes, but psychokinesis is not going make SPFT read a MTK Droid Backup.

BTW, What happens if you simultaneously depress power on and volume up on the RCA? Hold them for a good 20 seconds at least.

[Android General] Tzul:
Um, guys, this discussion is kinda off-topic here.

[MENTION=4717484]nannycrick[/MENTION] So, you used MtkDroidTools to make a backup of the RCA tablet? And you have a scatter file produced by that? That should be usable. MtkDroidTools should have produced both image-files and archives for the system partition and other ext4 partitions. With the SPFT, you can only use the partition images, not the zip/tar archives.

Those 1.3.51.zip and 1.9.50.zip files that [MENTION=7184758]charlestek[/MENTION] found are intended to be installed via recovery. They contain a "scatter.txt", yes, but that's not the format the SPFT expects.

1.9.50.zip contains a preloader and bootloader image (preloader.img and uboot.img), which could be used with the SPFT. However, the preloader.img is bad, it contains too much data at the beginning and end. I cleaned it up here, added the bootloader (lk.bin = uboot.img), and also added a scatter file that should work, if you have none (I set the size of the userdata partition to 256 MB, which is probably way too little, but I have no way of knowing the actual size). Anyway, this is not enough, you need at least a boot and system image, maybe also secro.
[Android General] charlestek:
[MENTION=4717484]nannycrick[/MENTION]

Maybe if you flash Tzul's preloader and bootloader ONLY, you could get the thing to boot. If it works, then maybe you can babysit Tzul's kids..... :)

Otherwise, I would start a new post at the end of the Xda RCA forum for your device and ask if someone has firmware or can dump their firmware and upload it for you.

I would be happy to babysit...anytime! I'm glad charlestek said something about that page2 download. It was bigger, so I deleted my previous copy. I've kept ALL files for the rct6203, the Tab2 in separate folders. I also loaded all stock KitKat & lollipop from your op, and made a proper scatter for the Tab2. Just in case! I haven't pursued fixing it, but I learned a lot about fixing bad tweaks in MTK devices as a result.

I've been thinking about the Lollipop ROM for my Tab2, but it runs great like it is. I do appreciate all the advice! Thanks! I'll try that cleaned up version you posted Tzul ! If it works..I'll definitely share over at Droidify's forum as well as a small posting at android forums, and Android Central where I got my first rom, Backside IHO for that OV. Thanks again!

On a Tab2 note...found a better version of Viper4AndroidFx that combines Dolby Atmos, and BeatsAudio soundfx all combined. There are different versions for KitKat , Lollipop, and Marshmallow. Guitarhero is the dev. I've been running it in the Tab2, and the Dolby enhancement adds debth to those big speakers! I think it's an improvement over plain V4Fx or just Dolby Atmos.

For anyone running the Fonter module for Xposed, they just included a great function. A Emoji changer to go with your stock keyboard. I'm using Google Keyboard w/Flat Style module, and it has emoji support. I loaded Apple Color Emojis, and Technical Regular font for the system. I have Times News Roman as an app font for WPS Office so my spreadsheets won't look/print wonky! My vanilla flavored Tab2 is "spicy" now! So far, no problems. Everything running smooth!
