Hi, I´ve been loking fo t a stock rom for RCA 10 inch tablet MERCURY II pro.
The specific name for this device is given on the bootloader. I remember something about Rev. 18.
Anyways, the tablet was working fine. Someone put a bad password and google security locked the device.
I deleted user preferences, tried wiping caches. Nothing. When the tablet restarts, asks for wifi, goes to the
"This deviced was recently wiped, please type the email account associated with it to restore all files and settings".
That´s my lock.
I went to fastboot, trying to send any adb command I could find on the internet, but I can´t work anything since
I get the error "partition not present".
So it all seems to point that I´m looking at a bricked tablet. Now I need to find the OEM .img of this.
I don´t know how to flash it via adb. I installed the quick adb drivers from other post here on XDA.
Please help.
Thanks.

Dear All
I'm a new android user, I just get a new A50 from Australia and try to root it. It's successful with z4root and I try to install Thai font to system. Unfortuantely I did wrong by deleting font folder in the system, therefore I can't run the system again. When I power on, it still have only garmin asus android logo and can't use it again. Does anyone please let me know how to restore or resolve this problem, or I have to throw it away? Thank you in advance.
Cheers!

Android 1.6 or the new 2.1 Eclair update?
It's a new Eclair 2.1 update, is there any solution?
Connect it to your computer via USB cable.
Using ADB, try this:
ADB REBOOT RECOVERY.
If it works, a yellow triangle appears with the green android guy.
Hit the HOME button. A menu appears. Use volume up/down to move through the options. Tap power to select it I beleive.
Reset/wipe to factory is one of the options.
If you need it, ADB is found in the Android SDK.
If that doesn't work, try calling in to Garmin for support.

Dear Spazmogen
Thank you for your suggestion, but I'm really new with ANDROID.
I downloaded ANDROID SDK and try to install but it dodn't work.
I use Win 7 64bit, do I need another software to run this command.
If possible, please let me know some previous post that already teach for beginner.
Thank you in advance.

ADB is a command line tool. But you will have to get Android SDK installed on the computer 1st.
Read the instructions for installing the SDK here: http://developer.android.com/sdk/index.html
ADB commands: HERE.
Interesting. I got into the recovery screen using the Quick Boot app,used the home button to show the menu. The arrows and volume buttons move, but can't actually do anything. Probably related to missing files that are reported in the data/cache/recovery folder.
https://www.garminasus.com/en_US/support/eclair/006-B1130-00.update
official 2.1 update came out today for USA GARMINFONES. Not the A50 Nuvifones elsewhere in the world...
Is the update different from the leaked one?
Sent from my Garminfone using XDA App
I am waiting for an answer to that question myself. I have no plans to change from the leaked version Garmin posted in mid-November.

Apparently someone did a bit comparison and said they matched. Plus, I tried and it told me it was the same version. On the plus side, I messed up my recovery partition and recovered it using the backups I made of each partition after I loaded 2.1 (dump_image). I made img backups and tar backups of all the files in 1.6 (I am anal about backing up). Good thing because 2.1 doesn't come with flash_image.
I can get into fastboot and the driver loads and stuff, but I get no devices listed when I do fastboot devices command. Next stop is Ubuntu
I know it works,just need to know how to get to it. Btw,I tried both the Garmin fastboot and adb drivers as well as adding the device hardware id's into the android drivers and neither worked.
I also need to find out if there is a similar enough kernel that I can use to get a fully functional recovery mode. I did find out that you can use adb just fine in the stock one and it loads a serial driver as well.
any possible way I could get that backup you made? I apparently didnt save my backup to the pc. And currrently I messed up permissions on my Garmin trying to get recovery working. I cant run the update or anything.
I've just stumbled across this forum post from google, I too am need of fixing my phone. All that is faulty is that the recovery mode has been overwritten with an incorrect one. Is it possible to extract the recovery image and reflash it from the optus supplied Android 2.1 006-B1130-00.update file?
Or is there a way of just getting say Rom Manager to work some magic for me?
Yes, it is possible... would be easier if someone could just use dump_image on a phone that has a working recovery mode and root access. I can provide the dump app and instructions.
Where can I get the Optus update, and are you positive recovery works on it? Does it also have working fastboot?
And to the other poster, which partition do you need? Btw, Rom manager has a permission fix mode. I can get you a tar file if it is the system partition or your choice of img or tar for the others.
And to everyone, after updating to 2.1, do a master clear because a lot of 1.6 apps are left over... duplicates.
Also, odexing all apps speeds it up a lot, with the caveat that you have to re-run the odex.sh file (found somewhere here and modified by me to be more thorough) after every app update or you will get force closes.
Oh I just reflashed the update again, and I got my recover menu back!
I'm not sure if i need any help anymore, but thanks for your offer of help merwin.
By working, do you mean that you can get to it with a hardware key combination and can actually select items?
first of all ,i 'm sorry for my english .my a50 is dead too.i also delet font folder and i use the adb command 'adb reboot recovery'.but the error is device not found. and my pohone can not boot .it stop at the android guy . how can i setup the device..Q.......Q......help me ..pls

Hello,
I was asked to forward my problem here so here it goes:
Not a long time ago I bought Asus ME302C FHD 10 and tried to root it. I followed a guide but I can't paste link just now.
Anyhow, the guide told me to flash rooted system image. I did every step correctly except that after i rebooted it, my device got stuck on logo screen, sometimes saying "no command".
I would like to undo that by getting unrooted system image for my device or rather get a working rooted system image. I am not sure about other possibilities as I am not experienced in android rooting or anything related. I do have fastboot up and working.
Thank you a lot in advance.
Edit: I figured out that Asus website has factory system images, however I don't really know which one to use because they all are for different countries and I am not sure what device is mine. Is there a way to check parameters of your device without booting it?
Edit2: I messed with the device more and found out that adb doesn't recognize device, as in, running 'adb devices' nothing gets listed. However, 'fastboot devices' does output my device, not sure where the problem is. Also, firmwares listed on asus website are zipped files and I don't know how to flash them. I tried 'fastboot flash system zippedfile.zip' but it would give me an error.
Solved
After few sleepless nights and loads of browser tabs opened I finally managed to fix my device.
All I needed was to use a different SKU firmware from Asus website. Now I can finally boot it thanks to XDA developers team and their useful information on the forums.
Hello. I'll try to explain my problem because I really need some help.
A few days ago, I was normally using my Tablet ECS TR10RS1 Intel®.... I turned it off, went to sleep and the next day when I was going to use it again, the OS didn't start, so I tried and tried until I found a forum where they led me to restore a backup file because the original firmware/rom wasn't still available.... publicly. I tried that, but in the process, I accessed the EFI Shell... That wasn't trouble at all, I just plugged the keyboard and typed "exit", and then it let me to the BIOS... And that's when my real problem began: I restored the factory setting default... and it involves "disabling USB ports".... Now, AGAIN, I'm stuck on EFI Shell. But this time, I can not type "exit" since the keyboard is not recognized by the Tablet.
Then I pressed Vol UP + Power ON and I get access to another menu "DNX".... And that's what brings me here to your forum:
I was briefly reading that one of your members managed to flash the BIOS via DNX, so I was wondering if you guys could help me do that to my tablet because I'm not planning to have a really expensive paper holder.
Thanks in advance.
Jinky.
Not sure about your case. But as your tablet use clovertrail chip like my zenfone 5 n fonepad7 170CG, then there's some methods to unbrick like via fastboot, flashtool, or intel factory flash tool... all of above are required a valid firmware, at least a IFWI package then intel FFT can unbrick anyway. So try to find your need, as i tried to help u to find it, but most of webpages use spanish, then i didn't understand anything

So I got a cheap android tablet and I wanted to root it. I was successful so I decided to install TWRP. I searched for my specific model and found an image on a german forum. I downloaded and flashed it and it got stuck in a reboot loop. So I looked at the image and it was for the QV1030. I tried to get it into recovery but couldn't. Many sources told me to hold Vol Up and Lock, and I tried this and more. Nothing would make it enter recovery mode. Then I read about SP Flash Tool and found the stock rom for the tablet and decided I would try to flash that. It kept coming up with an error, and every source online told me to format the flash except for the bootloader and then I could flash it. So I did. Now it doesn't show anything on screen, and SP Flash Tool comes up with error 6045. But it does show up in device manager under com ports as, "MediaTek USB Port" so I think I can still do something about it. I don't have any backups. I don't know what I'm doing. I require assistance please.
So I reflashed the entire backup and it come up with no error. The logo comes up and it plays the chime. The logo does this little shimmer effect and once it gets to this screen, it shimmers indefinitely. If I plug it in, it begins installing a driver and then stops part way through.

I left it for about 5 minutes and it finished the driver. I thought it froze but I was wrong. It shows up now on device manager under Portable Devices as, "MTP USB Device". I tried to see if it was listed as a device by ADB. It is not. Lets just say I've already learned a thing or two about this stuff. Good thing I did it on an 80 dollar chinese tablet and not my HTC One M9

I got it to work again mostly. So I realized that I wasn't flashing the whole backup. Some things didn't have a path and I had to set it manualy. Now it has CFW for some reason, but I reset it and it works now. The only thing is WiFi is not turning on. Any ideas about that?

I actually want to upgrade this from Android 4.2.2 to a more recent version. Do you guys have any ideas about that?
So I've come to the conclusion that while the device is no longer bricked, the current installation is written over the old one and things are conflicting. I know this because I looked through the cache and found filenames referring to apps I had installed before breaking it. So would the solution be to wipe the system partition and reflash the system.img so everything is fresh? Or does the problem lie elsewhere.
I formated the system partition, used SP Flasher to flash system.img and then did a factory reset. The issue has still not been solved. And now that I have done that, I don't have root access anymore. Framaroot says it was successful and I restart and check root explorer on ES File Explorer and it doesn't work.
I gained root access using a different method. However the WiFi still doesn't work. I think it may be that the mac address information was from the backup I flashed from the internet, and therefore doesn't match. I found a guide that tells me how to hex edit a file and put in my real mac address, but it's unavailable under wifi. I don't have the sticker on the back that says it either. How else can I find it?
Turns out the mac address can be anything. I used SN Write tool and an AB DB for my chipset and it still didn't solve the problem. I have no idea what to do. Can anyone help me?
I fixed the issue by grabbing a different backup from some russian website and flashing the system.img and secro.img to it. It now works fine 100%. Thanks

Hey man! I have the same problems with my QV 830. Can you give me the link for system.img and secro.img, please?
Hi all,
Hoping someone might have some knowledge on this Chinese cheap build tablet.
Its an iRulu eXpro X1, model X10. Inside is the Allwinner A83T with 16Gb Rom and 1 Gb RAM.
This was previously with my daughter but we just upgraded her to a Sumsung Tab A, so I thought I'd play with the iRulu (bad mistake lol).
The iRulu was still running kitkat so I rooted it (Kingo Root works fine in anyone else is trying), attempted to install CWM and TWRP. Both failed, every attempt through adb / fastboot gave bootloader: secure mode fail error.
So I them decided to flash the new rom from iRulu's website - using PhoenixUSB.
All was going well, the tablet went into download mode (hold Esc button, plug USB cable in and press power button 10 times in rapid succession.) and the firmware started to download. At 80% PhoneixUSB threw a boot(0) error and stopped.
After this the tablet will not start (nothing on display) nor even show the charging icon on the screen! It does however still enter the download mode so I can try other images. So far I have tried 5 different images (including darkglow10.1_android5.1.img, A83T_N102_N1021L1BC_20151123.img) however all of then error when writing to the bootloader. I have also tried PhoenixCard to write an image in Startup mode - this gave nothing Live Suite makes no difference either, using the images I have.
Unfortunately the serial number has worn off the device so I cant be sure of the exact firmware from iRulu website to install. (I've mailed them for what its worth).
I have opened the device and the pcb is marked INET-N102-REV01 and Zeng-gc2014-12-22. Google has some stuff on it but nothing I understood
Does anyone have any thoughts? I'm concerned that the bootloader is locked / corrupt in some fashion which is stopping the download.
thanks
update: using the x1081 firmware from iRulu and PhoneixCard I have restore functionality. The device thinks its an expro x2 plus and it doesnt recognise the SD card slot (tried multiple cards) but other than that it seems okay
Will try to figure the correct firmware thou - anyone?
thanks
Having the same issue
Hello, I am having the same problems with that tablet, got it from this girl I'm seeing. It was freezing whenever it connected to the internet, I assume was a ROM issue, i flashed an incorrect recovery on it after getting frustrated. Can you please help?
