How to Venue 7840 bootloop problem? - Dell Venue

Hello, as you can see the title, because of my stupid friend, my tablet can't work well now..
He set the password in my tablet and I didn't even noticed at that time.
After I asked him the password, He told me He forgot it.
Unfortunately, that was true, so for unlocking the tablet, I did the wipe data and factory reset.
That was the problem.
After did that, my tablet starts to bootloop, just showing the dell logo.
I tried to access the recovery mode again, but all I can see is that the broken robot, and can't go next step.
I searched the similar threads and I found that if I can approach the fastboot menu, it is able to unbrick the tablet.
I could approach that menu which I can choose normal boot, power off, reboot fastboot, and recovery mode, but that's it. I pressed the volume buttons (up & down simultaneouly) tried many times to recovery mode but after did the factory reset, it couldn't do it again.
Could you give me some advice to solve this problem? I'm looking forward to getting the solution. Thanks. :crying:

I followed the steps which you told me, and I could flash that files.
But after did that, it made the tablet freeze, not bootloop.
The screen just shows dell logo and didn't work well. I waited for 15 minutes, even more but it didn't work well.
And still I can't approach the recovery mode. Just I can see the broken robot..
Is there anything I can do? Hope to get advice :'(

Help!!! My Samsung galaxy player is bricked! (i think)

hello, my name is shahrukh and i need some help. i downloaded animmod (from 4shared) and then i donwloaded busybox. then i pressed blur and then it asked me if i want to reboot it. i pressed yes. this is when the problem starts. It turned off and then it turned on half way and then it turned off. it kept doing that and then i just left it for the night. in the morning it was not doing anything. when i held the power button it turned off and on for like two times and then turned off. i cant even start it up so i have no idea what to do.
i don"t know what to do
please help!!!!
Okay, we need details, describe exactly when "halfway on" is. We need your full model number and rom version (if you know it). Have you tried plugging it in to charge? Does it show anything now that you try to boot it? try holding volume up and powering on to enter recovery menu.
details
ok so when it turns on it says samsung. then after like 10 seconds it turns off. it does that for a few times and then it just goes in a black screen. the model number is YP-G7OC/NAW. when i plug it in to charge it goes on and off two times and then off. if it has low battery it just shows the sign. as for the rom i don't think i have any. i just rooted it using superoneclick. if it goes to recovery mode what do i do?
thanks!
(you got me really fired up when i saw the recovery menu!)
If you can get to recovery menu, try a factory reset, and clear cache. I am not sure if there is a recovery rom for your device, you should check samfirmware.com
tried both of them...no luck. and i couldn't find a recovery rom on samfrimware.com.
Your device has capacitive or mechanical home button?
it has a capacitive home button...the usa version

The phone boots in recovery?
If so, I can investigate a little more what's happening.
I'll try to post a return-to-stock image soon... The problem is that mine is cluttered with crap that the zergRush exploit added (it insisted on installing busybox instead of just rooting...)
(I'm not sure, but I think someone else already posted a stock zImage and system image...)
Here is the post about fixing capacitive buttons. A quick search of forum should have found it.

nooooooo!!! you guys have all got it wrong. first of all it doesnt boot in recovery. the only way to get in recovery mode is when it shows the battery sign i hold "up volume"+ power button.and the capaciative button is completely fine. im just stuck in a bootloop (i think) and it has nothing to do with a broken capacitive button! i will try to post a video today to show you guys exactly whats happening.
i kind of had the same problem, one time i thought i had entropy's kernel on and i had CWM well i didn't but i still thought i had so i tried rebooting into recovery using the terminal:
su
reboot recovery
then i turned off and went to this weird recovery menu it had four options, reboot system, apply update from SD card, wipe data partition, and power off and it had a ton of red letters and words saying like, couldn't access data partition or cache partition and couldn't access /data/media, or system, and then i just turned it off because i wouldn't let me choose an option, and then i got stuck in a loop but not during when it says SAMSUNG mine happened during the animation music part that look like fireworks and then SAMSUNG would light up blue then go through it again and 2 more times then go black and i tried flashing the US stock ROM in download mode but still would go through the loop and it doesn't even charge so i got nothing
so did you somehow fix yours? and i never got a recovery menu that showed something about shut down.:confused
Before brick
xxxxxxxxxxxxxxxxx
wait....are you asking me those questions? just to tell you im no developer or something. im just a 12 year old who has his galaxy player stuck in a boot loop. you have to make another thread if you have a problem.
sorry!
Ok. : ) You got it wrong. No problem. His case is different from mine. Just wanted to use her Brick in case. Nothing more. good luck.
I resolve my doubts alone. Nothing that Google does not respond. haha
At least before brick.
ok. let me ask google too xD
anyways..anyone have any idea of how to fix this boot loop?
im trying to do the Linux thing by running the ressurector ans the VM windows the forum is posted under development called hard brick recovery for galaxy 5.0
ok.(i have no idea what you are saying...just saying!)

[Q] Stuck at encryption unsuccessful - Impossible to factory reset

Hello,
This morning, I was reading comics on my tablet, an it froze completely. The touchscreen and buttons were not responding so I held the power button to turn it off. I turned it on again, and I had an "Encryption unsuccessful" message, saying that I needed to perform a factory reset. The problem is that I never set up my tablet with encryption...
That being said, this screen pops in when my tablet starts, and there is nothing else I can do but to turn it off. I tried the following :
Reboot
Reboot to safe mode
Launch the recovery mode and launch the Android icon (I don't know what it's here for)
Launch the recovery mode and launch a factory reset
The factory reset starts for less than one second before showing the Android sign with a red alert triangle, and resets the tablet. At this point, nothing worked, I am still stuck with this screen, I don't really see what I can do.
I bought my tablet in the US in 2012, it runs Jelly Beans if I recall correctly (the ASUS version, I never rooted it). I have a Mac running Mountain Lion if it can help. Does anyone know what I can try now ?
Thank you in advance for your help

No, it is the default bootloader. Everything is standard, I never felt the need to modify the OS of my tablet. Do you have a theory?

[Q] Oppo Neo 5 Softbricked

Hi guys, I really need your help.
I'm new at this rooting stuffs and I tried to root my Oppo Neo 5.
I tried so many softwares like OneClickRoot, FramaRoot, and Kingroot but none seemed to work.
So I resorted to an app called oppo tools
It worked at first but I got really annoyed when my status bar suddenly colored to red when my phone discharges to 15% so I unrooted my phone and rooted back again. I really thought that was going to fix my problem but that's where the bootloop issue started.
I tried to flash some custom recovery zip but it failed since I only have a stock recovery.
But the thing is, I found a guide that says to rename the clockworkrecovery img to PG86IMG.zip.
So I did tried that and as soon as I flashed the zip from my stock recovery, my phone hanged.
I long-pressed the power button to restart and boot into recovery mode but nothing seems to happen.
I'll try to explain a bit more on how it looks when I boot my device.
When it boots normally (I mean not pressing the volume to enter recovery mode) it will only show the logo but when I try to go into recovery mode it will show the logo with a little text on the lower left portion "Recovery Mode"
Before I flashed the PG86IMG.zip, recovery mode was still working and the charging screen when off is working too.
but after I flashed the zip, every time I try to recovery mode the logo shows up with the little text but RECOVERY MODE isn't working. When I charge my phone it automatically boots up and shows the logo and text like it's trying to go recovery mode (I'm just trying to charge? It's going to recovery mode)
I tried using "adb devices" on cmd but it's not detecting any devices.
I'm really out of ideas guys, I know not all people use this model but what would be your suggestion?
A suggestion on how to fix this would really be appreciated :good:
I'm sorry I'm really new at this, please correct me if I did something wrong starting this thread. :angel:

Oh, I'm sorry, I didn't notice.
Lately I can't access the recovery mode but now
I'm currently on Boot-loop and I can enter into recovery.
The ColorOS recovery mode only have limited function that I can mess around.
It only has the apply update, wipe data and cache, reboot, power off and system file verification.
As always I already did wipe the data and cache but nothing happens. Still boot-loop.
What should I do?

You made a soft brick, not to worry flash it with correct stock firmware, if the phone is in warranty than ask them to do flash, this will take approx 10-30min. If it isn't in warranty than you should try it own or else pay some amount and the rest they will do.

Stuck in bootloop, potential soft/hard brick

Hello XDA.
After whipping my Moto E out the other day, I noticed that turning it on results in it just... laying there and showing me the "WARNING - BOOTLOADER UNLOCKED" message.
Around 1 1/2 years ago, it just turned itself on after clicking the power button once. Now, not even Fastboot mode helps, as choosing any of the options listed there results in the warning mentioned above. For clarification, here is everything in short:
The phone does NOT turn on normally
Using any option in the Fastboot boot menu restarts the loop (i. e. instantly goes back to warning message)
NEITHER does Minimal ADB and Fastboot recognize the device, NOR does the phone recognize the connection to any PC (I've tried 4 different PCs)
Since Fastboot is unresponsive, suggestions to restore stock recovery are useless to me
Suggestions to perform a factory reset are also useless, since Fastboot is unresponsive.
So, am I right if I suppose that this is a hard brick? Or is this somehow salvageable? If so, please help me...
Thanks in advance!

If its stuck on boot, its definitely not hard brick.
What was the android version when you wiped data?
Was there any custom recovery you used to wipe data?
You possibly wiped /system too, wiping system can result in bootloop.

Sorry, but that doesn't make sense. The phone's been rooted for almost 2 years now, and 1 year ago, it turned on perfectly fine.
But let's assume that actually happened somehow, how do I recover from this?

Stuck in bootloop Neffos X1. No recovery mode.

Hello community,
I haven't posted here before, so I hope I'm not doing anything wrong.
I have a problem with my Neffos X1 and after browsing the internet for hours nothing helped so far, so I hope some of you can help me out.
My phone is stuck in a bootloop since yesterday evening. I haven't done any updates or new installations recently, so it just happened out of the blue. It loads till the Neffos logo and then restarts over and over again.
Since I can't take the battery out, I tried letting it run out of energy and then restart, but as soon as I connect it to a power source the bootloop will start again.
I read a lot about getting it in recovery mode or to try and flash it, but no matter what combination of buttons I try, nothing is happening. The phone basically doesn't react to anything and just keeps restarting. The only thing I noticed is, that when pushing both volume keys the screen will just stay black (no restarting), but after letting go the bootloop will start again.
I tried flashing it via SP Flash Tools, but the phone also doesn't react to it.
Lots of troubleshooting guides also require, that I have rooted my phone in the past, unfortunatly I haven't. I also read about unlocking the bootloader, but since my phone isn't reacting to any buttons and my laptop also doesn't seem to recognize my phone (probably because it doesn't boot proberly), that doesn't seem like a solution either.
To summarize: I'm stuck in a bootloop with no recovery mode, no rooting, no unlocking bootloader, probably can only use my laptop to do anything remotely.
So, is there anything you can think of, that might help me get out of the bootloop? Or ideas of what I may did wrong when trying the other solutions?
Thanks for any help in advance.
Same problem
I have the same problem, I have tried all kinds of soft reset and nothing is working I also opened the phone to check if anything was not connected properly, but everything seems fine except for that infinite loop. Please help!

Try this
Download phone's Stock Firmware onto your personal computer.
Install the USB MTK Drivers - NOT ANY OTHERS (skip if you have them already installed).
Download and Launch the Smart Phone Flash Tool (SP Flash Tool)
Click the Scatter-loading button to navigate to the Stock Rom you just downloaded.
Select the Scatter File from the extracted Stock Firmware on your computer.
Select the Download Only in the SP flash tool option
Click the Download button to start the Formating process.
Connect your phone via USB to the computer>> holding volume + and volume – button of your phone at the same time or holding power button only so that the flashing process will starting working
Patiently wait for your device to be formatted.
After the formatting is done, a Big Green button will pop up on the SP Flash to show that.
Unplug phone and boot it up.
If you have a boot loop after booting your device, boot into recovery mode and do a factory reset.
Voila, you are all good.
