I found a ROM over the Internet which purported to be Android Lollipop 5.1. To install it on Prestigio Multipad Ultra+ (PMT3677_Wi), I installed ROM Manager on the device, but it is not able to detect and install the zip that I loaded on the SD card. Also, when I hit "Reboot to recover" option, it reboots the device into a an Android picture lying on its back with a red warning sign on its opened belly. It does nothing and after a few minutes reboots to normal.
Contents of the said Lollipop zip is as follows:
>
boot.img
nandroid.md5
recovery.img
recovery.log
system.ext4.tar
system.ext4.tar.a
I tried to flash recovery.img onto the device after taking it into recovery mode (where the static sick Android picture with red warning appears), but adb does not recognize the tablet, so I can be able to enter the following command:
Code:
fastboot flash recovery recovery.img
which prints "waiting for device". The official way to install stock ROM on this device is to download sun5i-android-a13-a86.img from Prestigio website and burn it (only this file) on SD using PhoenixCard tool, then insert it into the device and reboot, a clicking sound starts along with a progress bar. When clicking sound stops and progress bar completes, the SD should be removed and device rebooted. Tablet is ready for use with new ROM installed. But, this is true for stock ROMs in case device is bricked, but I don't know how to flash the above-mentioned zip for Lollipop on this tablet. Any ideas on how to do this?

DO THIS AT YOUR OWN RISK. YOU COULD PERMANENTLY DAMAGE YOUR DEVICE. READ ALL DIRECTIONS BEFORE ATTEMPTING.
These tablets are an LY-F1 clone. So most of the stuff that is compatible with an ly-f1 will work for you.
The model I am referring to and have personal experience with is the following: Trio Stealth Pro 7c
The Trio already comes rooted. I accidentally un-rooted mine AND I ended up with the 0.00 internal storage error. It would not let me download or install apps already on my SD card. To install a new (custom) ROM you can follow this quick guide I put together.
First...
Things you will need to Download;
CWM Recovery for the Trio Stealth Pro 7c : CWM Recovery 6.0.1.2 for Allwinner A10 LY-F1/TREQ Tablets
Custom ROM for the Trio Stealth Pro 7c : Choco Ice Cream 4.0 BETA1 for Allwinner A10 LY-F1/TREQ
32 or 64-bit Windows ADB Drivers : Windows ADB Drivers for Trio Stealth Pro 7c
ADB needs to be downloaded and installed/setup via the Android SDK found here : Android SDK Download
1.) Download CWM Recovery
2.) After your download is finished go ahead and extract the contents to the SD card. I connected to my PC and put the extracted files (there are 3 files) on both the internal storage as well as the removable micro-SD just to be safe.
3.) Download Choco Ice Cream 4.0 BETA1 Download Choco Ice Cream 4.0 BETA1
4.) After the ROM finishes downloading DO NOT extract; just copy the whole .zip file directly to the Micro-SD Card as-is.
5.) Connect your Trio to your Windows PC with a USB cable. Make sure you go to settings/Developer Options/and turn on USB Debugging. I had to open device manager and manually install the ADB Drivers for Trio Stealth Pro 7c. You can check to see if the drivers are installed by opening a command prompt on your computer. You would do this by going to start and typing CMD into the search bar. Or you can click on Run and type CMD into the box. This should open your command prompt. Enter each line one at a time, pressing enter after each line:
cd/
cd androidsdk/platform-tools (some of you may have to type just "tools' depending on which version you have)
adb devices
After hitting enter you should see your device's serial number. This shows that your device is connected and was found. If you do not see your device serial number either you don't have the correct drivers for your device or you did not enable usb debugging mode.
6.) Now we're going to start the adb shell by typing the following, again, pressing ENTER after each line of text.
cd\
cd androidsdk\platform-tools
adb shell
You should now see one of the following symbols:
# or $
Now type the following, again, pressing ENTER after each line of text
cd /mnt/sdcard
sh install-recovery.sh
sh reboot-recovery.sh
After pressing enter, you will see your tablet reboot into recovery mode. You can use the volume buttons to move up and down and use the power button to select. To get back into Recovery Mode if you reboot out of it or your tablet turns off; go ahead and turn your Trio completely off. Once it is shut down press the center of the volume button until the WHOLE thing is pushed in. Do this WHILE holding down the power button. Keep it held for a few seconds until you see the the screen come back on. Once you see it, you can let go and it will reboot into recovery mode.
7.) From Recovery mode:
MAKE A FULL BACK-UP FIRST. DON'T IGNORE THIS STEP!!! IT MIGHT JUST SAVE YOUR DEVICE ONE DAY!!! When the backup gets finished go back and then:
SELECT: INSTALL ZIP FROM SD CARD. (press the power button once to select it).
If you placed the ROM on the micro SD-card then you should select 'Choose zip from sd card' if you placed the ROM on your internal SD-card you should select: 'Choose zip from internal sd card'. Now find where you placed the ROM/download. Use the volume buttons to scroll up and down. Once you find it, select it with the power button. Scroll down until you see 'Install choco ice cream 4.0beta1_LYF1.zip'. Select this with the power button.
8.) It should now start to install. This will take maybe 3 minutes tops. Just be patient. When it's done, wipe the data and the cache. (it was one of the options listed when you first start recovery mode)
9.) SELECT: GO BACK; then choose REBOOT or REBOOT YOUR DEVICE or whatever and wait for the device to finish restarting. It takes several minutes to finish booting up; be patient; it will get done sooner or later.
10.) Your Finished

How do you rooted the trio-stealth g4 7?
Tried safestrap, backup failed
I installed safestrap with your instructions. adb was not able to be downloaded for my device given the link you provided, but I had another version that I used from Android Multitools to perform the safestrap install. Only problem is now that I've installed safestrap, it boots into recovery just fine. However, that's the only thing I can boot to. I can't boot normally, and my backup using safestrap failed at /system (error was something similar to "could not mount /system!".
Any suggestions? I would like to be able to boot normally and backup fully if I can, I'm kinda worried about reflashing into the custom ROM and not being able to recover.
UPDATE:
This safestrap installation did not work for my stealth trio 7c A13. It actually prevented my device from booting, and when trying to install the choco rom, my device not only bricked but my SD card was corrupted as well. Not saying it's the ops fault at all, I know the risks when performing tasks such as these. I just want everyone to be aware.
I was able to restore my brick using the livesuite software and flashing with an image of 4.1 that I found from a different site. If anyone would like more info, ill be happy to provide it. My new rom is Google play good to go, so im happy. :thumbup:

Hi guys . I need your help ..
I have a Firefly Intense X and i rooted it using Kingo and it works fine .. Then I downloaded Pimp My Rom to customized my rom .. I had fun customizing it and it always works fine. Then i'm not contented with my phone's performance so I adjusted it again until I bump in to the adjusting its dpi. I'm not sure if its under Dalvik VM or kernel tweaks .. Then adjust another thing . I don't remember what it is but I remember that it has 'step n1' then again , I adjust something then I click the last step the 'step n(x) - reboot' . then after that , it reboot over and over and over again .. I mean it will show the Company logo the the boot animation then it will go to the homescreen then says download failed after a few seconds , it will go back to the boot animation then go to the homescreen then reboot the again and again and again ..
My phone is recognized by the computer at the device manager under Adb Interface as HTC Dream but my phone is Firefly Mobile. I thought it will appear under 'Other devices' with a yellow warning sign but it's now . I'ts under Adb Interface. I tried to unistall it many times but it is always an HTC Dream. I also downloaded the adb setup 1.4.2 .
I wipe factory data and cache but it is still happening. I already try to go to the fastboot and unlock but i can't unlock it . It says volume up for yes and volume down for no, I click my volume up and nothing is happening. And I also tried to " adb push <filename> /sdcard/. " and it says 'no such file or directory' but the file name I inserted is correct and it is placed to the correct folder. I also tried to removed my sdcard and direct it at my pc and put a new downloaded custom rom and insert it again to my phone but I can't find it when I choose to 'apply update from sdcard'.
NOTE:
I can go to recovery mode and fastboot mode (locked) only not on a CWM.
Please please please .. I need a solution for this problem. And if you have please make it a step-by-step process.
I need you guys .

Hi,
Thanks for using XDA Assist Please post here Android Q&A, Help & Troubleshooting

Hi, I have a Lenovo K1 Ideapad (routed Android 3.1, 2.6.36.3 kernel version. ROM version: K1_A301_02_02_110930_CA ) and I am wanting to upgrade to a 4.2.2 Custom ROM or higher , but I can't get my tablet to go into recovery mode. I have tried doing it manually (hold Vol+ and vol- while holding power) but it goes to boot up and all I get at that point is an all black screen and my side swipe sensor LED's light up and stay on. The screen is black (fully). The recovery screen doesn't show up. Even after waiting for 30 minutes:. I can still boot it up normally, and it works. But no recovery. I have also tried adb, and various terminal apps, but they only reboot my tablet - regardless that I type "su reboot recovery" or the other similar commands. I have tried using ROM Manager, but the k1 isn't supported and when i press the reboot to recovery option, the k1 just reboots normally. I have rooted my k1 using this method:
1. Extract K1Root.rar to the directory of your choosing.
2. Connect your tablet to your PC with the USB cable.
3. With your tablet off, press POWER+VOL_UP+VOL_DOWN until the screen turns on, but displays only black.
4. Windows should detect the device, but not install drivers.
5. Go into device manager, select the APX device, choose update
drivers, and install the drivers from the aptly named NVFlash_Drivers
folder.
6. Open up the NVFLASH_HOME folder and run the file K1Flash.bat
7. Make your desired choices when prompted, and enjoy.
I downloaded superuser, ROM Manager, Busybox and root checker. and
checked the status of the root, and it said the root was successful. The tablet ran well. But as I played with it a bit I found that an alarming amount of apps were becoming incompatible (ones I had wanted before rooting n stuff). One game that was preloaded was no longer playable (until they updated it a few months later), More and more apps now aren't compatible with android 3.1 anymore, thus me trying a custom ROM. All instructions followed were for the K1 Ideapad. I am now noticing that various processes are now coming up as needing to be force closed, like the launcher process for example. I am at a loss of what to do. Do you have any advice? Thanks in advance!

Hello,
I do not speak English, i translate this text with a translator online, thank you for your understanding.
I buy 2 identical tablets of the TrekStor brand.
Model name: ST10416-7a
Processor type: QuadCore-A33
Kernel: 3.4.39
Build Number: ST10416-7a_20150925_V1.2.2
Firmware version: V1.1.9_20150917
The tablets are "root" method.
On one of the tablet i deleted files important! :silly:
Now it starts until logo "Android".
Another problem, i can not install a custom Recovery (CWM TRWP).
Unfortunately, I find this not the right firmware.
To save the tablet , I think do a " dump" or " Nandroid " with the tablet that works.
I followed the tutorial "Making Dump Files Out of Android device scores" of the site XDA-Developers.
I extracted: boot.img, and recovery.img system.img.
Then i made a package ".zip"
I turn on the tablet in recovery (power + volume up).
That the Recovery Menu:
Reboot system now
Apply update from ADB
Wipe data factory reset
Wipe cache partition
Apply update from external storage
Apply update from extsd storage
Apply update from usbhost storage
Reboot to bootloader
Power down
View recovery logs
Click to expand...
Click to collapse
I selected the "Apply update from ADB" option to install my package "zip"
I open a terminal and type the command:
Code:
adb devices
He turns to me: "03389948c80500000000 sideload"
Then i tape.
Code:
adb sideload update.zip
The tablet me back:
E: footer is wrong
E: signature verification failed
If I try to other controls with "sideload" (adb root or adb shell...)
He turns to me:
error: closed
Thank you for helping me.
