[Q] what if /system/app deleted? - Viewsonic ViewPad 7 & Variants

Hello,
I have a problem that, while I was trying to delete some systems applications by mistake I managed to delete whole /system/app directory.
It is in the boot screen and I have three birds for hours.
I cannot adb shell I have some other tablet to get image if required.
Can someone help me with that issue as it is so important.
Regards,

You could try re-naming the FW file to update.zip and copy it to your sd card. I don't know if it will work but it appears that it may.

Thanks for the reply, which FW you mean?

There's a link to it in this forum. It begins with FW_SAM

Click on this link and read the first post. It will tell you how to get the file.

Sorry, it's not the VSAM, it's the VSEI. It will take your device back to stock, if it works. Download the file and then rename it to update.zip. Copy it to your sd card and boot into recovery. It's worth a try. Please let me know if it works.

Hello again,
I am trying to turn it on but it is not turning on. I tried to connect computer volume and power button, reset nothing seems to work. How I can enter recovery mode?
Thanks,

I assume it's fully charged or connected to an A/C adapter. Then hold power and volume until it boots. As soon as you see the bird logo, let go of the power button but continue to hold the volume button until it boots into recovery. Then, select "update from SD card." It will only recognize update.zip file because we don't have clockworkmod recovery for 7e.

I don't have any other ideas. We really need a custom ROM with CWM but I don't know any Devs working on it. If your tablet is less than 30 days old, you can return it for a full refund or replacement.

I understand thanks fro your help anyway will let you know about the situation.

[Q] Transformer prime stuck in bootloop. Not rooted. Bootloader not unlocked. help!

I tried turning on my Asus TF201 transformer prime the other day and now it is perpetually stuck in a bootloop.
I am able to access the menu with recovery, fastboot etc, by holding down VOL- and PWR. I tried doing a data wipe from this menu but it did not solve the problem.
I have not rooted or unlocked the bootloader! Do I have any options from here to try and get this thing working again? Should I just RMA it back to Asus? It is not longer covered by warranty.
While browsing the forums I found several threads similar, but it most of those situations the users had already unlocked their bootloader/rooted.
As far as I know the tablet was up to date with the latest stock firmware/OS from Asus. I know I am a noob, is there something simple I am missing?
Any help you can provide is very much appreciated! Thank you so much for your help!!!!
Can u enter bootloader? If u can then u can easily restore to factory settings and u will be ok though u will lose all your data and apps though can be restored easily from play store by syncing.

By bootloader do you mean the menu you get when you hold down VOL- and PWR (it give you 4 options - recovery, boot, fastboot, and wipe data)? If this is the same thing then yes I can access that. I already tried the wipe data option which did not seem to fix it. Is this what you mean by restore factory settings?
Thanks again for your help!

Try using the instructions at the top of this thread --> http://forum.xda-developers.com/showthread.php?t=2230779

Download latest firmware from Asus site.
Unzip this file once - it contains a zip inside it. Rename this zip to EP201_SDUPDATE.ZIP
Copy the file to the root of a FAT32 formatted MicroSD card
Turn the tablet off via the power button.
Now turn it on holding down the Volume Down button on the tablet
In a minute you will be in the recovery screen. Hit volume up.
Wait for it to get done. It can take a while.

[Q] Dell Venue 8 3830 won't boot

My Dell venue 8 3830 stopped working yesterday. It started with the "com.google.process.gapps" process has stopped working", which is a common error that can be fixed. However, it kept coming up and it wouldn't go away. After a while, other apps started crashing as well. I restarted into safe mode, however it just booted into the normal OS. I wasn't able to wipe the tablet either. When i pushed the "erase everything" button, it wouldn't do anything. I was able to boot into recovery, and i hit the restore button. It then proceeded to try to reboot, then gave me an error screen with the text "No Command". I then plugged it into my PC, where it booted to a screen with a picture of a USB symbol with a white bar underneath. I unplugged it and now it wont boot. All it will do is flash that USB screen. I'm thinking the OS corrupted or the Hard Drive has started to fail. Any ideas what the problem could be?

Okay, this unbrick method will install 4.3 and change your splash screen to the "Intel Inside" one instead of the original Dell logo. I also believe you will have to root to update to 4.4.2 which will void your warranty. It's a last resort type solution.

before you do that, try to go into fastboot mode, by holding power and volume down
*make sure you device is unpluged
If that works you can select recovery, then hold volume up and power for a few seconds, and then you should be able to select wipe data

If I'm not wrong
The recovery of the android lying is a stock recovery and only will let you install the developer edition, but is 4.3 and in my tablet sometimes the instalation fails.
If you want to install zip roms you need a custom recovery
If you don't have custom recovery an option is installing stock rom images from fastboot.
Hope this help you, even with bad English

You need to flash the files for your device from here http://forum.xda-developers.com/showthread.php?p=51090040. First unzip the FLASHPKG, then flash the boot, recovery, system and fastboot. Then flash the two .bin files in the ifwi folder.

Yes it does. I mentioned the penguin specifically:
Seeing the penguin is normal. I have managed to fix the issues I have and I am running a custom ROM by Cuoco92, all thanks to the help I got from @simidisc.
I will assume that you have installed all appropriate USB drivers.
1. Visit http://bit.ly/1Q6irPH and download SEZIONE FIRMWARE and SEZIONE RECOVERY. Don't worry about this being in Italian - I don't speak Italian and managed no problem.
2. Copy the zip file from Sezione Firmware to your phone.
3. Unzip the the recovery file on your computer and connect your phone to your computer.
4. After unzipping TWRP, run "Install Over Fastboot".
5. Your phone will reboot and you will see THE PENGUIN. Just press VOLUME UP + POWER at the same time and your phone will reboot to TWRP.
6. You should now be able to flash the ROM, making sure to wipe cache, dalvik etc.

TWRP Fastboot
I am having the same problem.
The penguin comes on then no matter what I do, it either just reboots (if I keep holding power down) and continues to do this for ever, or boots into the LeEco recovery, if I press volume up and power, or just boots into EUI rom if I do nothing.
Any suggestions?

Need help recovering data from a bricked G925F

Hello, i'm trying to help a friend recover his data from a galaxy s6 edge he bricked. He bricked it while using a software that was suposed to recover a deleted file
Now the phone cannot be shut down, it`s in recovery mode and can be reset with power and volume up down key , and get into download mode.
Good news is that he said he had activated debugging mode but he does not know what version of android he had(i'm thinking 5 or 6 )
Ok so the main goal is to get the data out , doesn;t matter if the phone is dead after that.
I did some research but i'm unsure how to proceed: as this is a phone without a sd card , the data needs to come out of the usb port. How can i do that? using a custom recovery?
Can i install a custom recovery if the phone is not rooted and bricked?
Is there any other method to get the data out?
Thank you

First of all... The phone is not bricked. Have you tried to reboot from recovery mode? In recovery click wipe cache then reboot. Any luck?
Does the pc recognise the phone in file explorer?
What exactly is the phone doing now? Stuck in recovery?
You can flash TWRP then using TWRP make a backup of data. It's hard to tell at this point if any data is already gone.
One thing to ask before you do anything.... did your friend have sync turned on in google/Samsung account and/or Google photos?
He didn't have sync turned on.
He'll come by later woth the phone and i'll see exactly how the phone is behaving

Try to make the backup of data only and see if it works. Alternatively do you have an OTG flash drive .

It shouldn't make a difference that the phone is not rooted. When TWRP first booted did you select keep system r/o or did you swipe for modification?
I honestly don't remember it asking anything but i would have chosen to keep

Try flash TWRP again and this time swipe to allow modification. Then try mount.
