shall i flash the preloader again ??

---------- Post added at 10:22 AM ---------- Previous post was at 09:30 AM ----------

i flashed the preloader yesterday ,can i continue flashing firmware or i need to flash the preloader again??
[Android General] NepoRood:
Once on the preloader, that should make the charging light come back on. Are you absolutely positive you have the x12x version of the device?

Because one is not compatible with the other, meaning you can't flash x12x firmware on a x9x device and vice versa
[Android General] sivansk:
i having version x.12.x only, i flashed the preloader too there is no charging light, i saw the version number i the recovery , how can i fix it?? shall i flash the preloader again...
[Android General] NepoRood:
Maybe the device is charged then, lol

If you got a successful flash on the preloader, you shouldn't have to flash it again. Just make sure it's not checked when flashing the firmware
[Android General] sivansk:
i flashed the cwm recovery of version x.12.x on my device and it worked , i confirms that i have the version x.12.x only!!

[Android General] NepoRood:
You can try re-installing the drivers. But I don't see how you can flash the preloader and not be able to flash the firmware...
[Android General] sivansk:

what will happen if we try to flash the firmware without flashing preloader??
[Android General] NepoRood:
To setup the Flash Tool on Linux, follow this Guide

The preloader from the Surf firmware is not compatible with our devices. You can flash the firmware, but not the preloader

what is nvram backup?
[Android General] NepoRood:
NVRAM contains data like WiFi and Bluetooth MAC address, Baseband version, IMEI/MEID number and other essential information. It is highly recommended to back it up on this device as you'll get a WiFi error on the "connections available" screen if it becomes lost or damaged.

Did you get your device going?

[Android General] NepoRood:
You need to follow the guide for setting up Flash Tool on Linux again and make sure you have everything setup correctly. Also, make sure your VM recognizes outside USB sources, or something like that. I don't use a VM, I boot Linux directly from my HDD.

To format the device, you change it from "Download Only" to "Format", then plug it in the same way as if you were flashing the firmware

[Android General] smartmanvartan:
There is a way. What you wanna do is grab the right firmware for your tablet. And use the flashing steps with the male/male USB cable but only flash the preloader. Then reboot the tablet and flash the whole firmware. That should bring it back. Good luck.

No buttons preloader only. Try it and see. Then flash firmware once you have the correct preloader. What was the firmware version on your tablet originally?

If you can get to recovery you should be able to get to download mode. Always have the official firmware on hand. I have trouble with this one myself, waiting to get where you are. I dont start a project like this without the original firmware. That way if you get soft-bricked, you can flash it in, start over.

You seem to have picked one of the most difficult projects here on XDA. These tablets RCA sells run really good for what they are. If you're trying to flash yours and having that much difficulty, slow down! You seem to be rushing things and this particular series of devices have many differences compared to flashing other Androids. I myself haven't figured all this out yet and I have two RCAs I'd like to work on.

---------- Post added at 10:36 PM ---------- Previous post was at 10:11 PM ----------

I have a model number which is slightly different. RCT603W87M. In the build number you referred to like version 9 or 12. Going by what you're saying mine would be 15. So I'm not sure I can use all of this. I have an older one I'd also like to upgrade, the RCT6103W46-ANDROID4.2.2-7T2-V27-V1.2.20, that would make it a 2 right. Maybe I could jump in here and try some of these things.

So, Smartmanvartan. Ive tried plugging the device in like you mentioned, having the device manager up when I plug it in. Barely 2 seconds if that. Nice to see you return to previous work. These RCA tablets are definately a challenge. I was thinking of just replacing the (they show up as MTK in the system) settings with an ADB USB interface. Would that have even worked. Rooting it was easy compared to the rest of it.
