Coby Kyros MID7127 Startup Problem

I have a Coby Kyros 7127, I cannot get it to get past the android cycle of the startup. Once the power on button is depressed, Coby appears, then it goes to android and that is where it stays... it cycles and does not go past that stage. I can depress the reset button and it resets. I can also depress the power button and sound button and it will stay on Coby, however in the bottom left corner, in blue, it says "The Device Enter Fastboot Mode, Please Connect USB To PC or Reset The Device, Waitting......."
I have watched many of the videos and cannot figure this out, I have tried many of the things online - the issue is, I cannot get the tablet to get far enough along in the boot sequence for my computer to display the tablet and run adb. This tablet is for my grandaughter and we were hoping to have it for her to use.
We would like to make it work like many of the videos state... any help is appreciated.

Were in the same boat. Here's some tips...

I am in the same boat! If you download ClockWorkMod from here on xda which you can do on this forum its the 2nd post from a guy named "the_kwa" you can save CWM on your SD card and use ADB commands to boot to into CWM. Once there you can try to do a factory reset. If that doesn't work, then you have gotten to where I am.
In short, you need to find a custom ROM for the tablet. I have scoured the interwebs trying to find one and the only place that seems to have them is a site called: Kyros Tablet Zone or KTZ. Now, if you are willing to pay $12 for a ROM from them, then your done. Tablet will be back up and running & your good.
My MID7127 is dead too. If you do decide to purchase a ROM from KTZ let me know and I'll talk you through how to install it step by step. If your willing to maybe share that rom with me and get mine going again! Let me know. bacause I was about to post this same issue until I found your post.
Either way let me know & hit the thanks button if that helped you out.

Fighting a lost cause?

I've got a rooted (Super SU, but the original root manager was Superuser) LG C800 that I was having problems with. To be specific, I installed some apps on to the system. Some of these apps would be Titanium Backup for root, Avast Mobile Security, ROM Tool Box Lite, Super SU, and a quite a few others. From day one they seem to be kicked right back to my S.D. card, but not all at the same time, and some would stay on the system. I read where I should move the apps back to my S.D. card and try to re-install them on the system minus the data. When I did, the phone went nuts. Now it stays in a restart mode but never fully boots up. Can I salvage it, and if so, please tell me how?! I have tried the hard reset/recovery boot where you hold down the power button, volume, and a few other keys, but it did not work. I'm a broke college student and can't really afford to buy a new phone. I used this one for everything including tethering it to get my assignments done at home and turned in on time. Please help! I'm open to suggestions....... My phone will be completely off. When I plug it into my computer, via U.S.B., it automatically turns it on whether I want it to be on or not. Then it starts off in "reboot recovery" mode, will boot all the way to the point to where the home screen would normally turn on, but then it starts in that "boot loop" all over again but never fully boots up before going back to the beginning of that "boot loop" yet again. I can't even get it to register on my laptop as being plugged in. The reason I took the apps I placed on the system off was because sometimes when I'd re-boot the system the apps would be on the system and sometimes back on my S.D. card without my involvement of any kind other than rebooting my phone. Is completing a Nandroid recovery or re-installation of my ROM even possible with my computer no longer recognizing it as even being plugged in? From what I can tell it won't be. Am I fighting a lost cause or is it salvageable?
Rooted myTouch Q 4G, a.k.a. LG C800
I believe it has a 2.3.4 GRJ22-perf, and then something like 2.6.35.7? I can't remember off the top of my head, and I can't pull it up on my phone anymore or else I'd double check.

Have you tried booting into recovery?

(More about my phone from the original post) Honestly.........I'm not what you may consider technologically inclined. I have however done about as much research online concerning this matter as any one person can do. I've looked it up on all major sites, and many smaller ones too, that post remedies for phone, or "human" if you'd rather, malfunctions. They all talk about still being able to reach a home screen or doing the whole holding the power and volume decrease buttons until I "reboot recovery" screen appears (if that's what you're referring to as doing a recovery reboot as). Don't forget the one where you hold hold the power and volume decrease buttons along with the "A" and "F" keys as well. I even tried one from here where you're supposed to push the genius button after the Android figure leaves the screen. My phone won't allow me to do either. Basically if it's online, I myself, or this girl that's been staying with me, have tried it without any results. On the initial boot the Android figure and the box with the arrow coming out of it show up and it boots until just about the point that it use to switch over to the home screen and it will start the whole "boot loop" over again. The thing is though that the Android figure and box aren't there any other time after the first boot, and with every boot loop it makes after that, the time is reduced from the beginning of the loop to the end when it starts all over again. The phone won't shut off unless I remove the battery and even though my laptop no longer recognizes the device, when I plug my phone into it or another power source and it's off, it automatically turns itself on and begins that boot loop all over again. there is one thing I have yet to try. I read on one site where I could download a custom ROM on my S.D. and then try reboot it, but it never makes it to the point in which the files on my S.D. card are ran, much less scanned. I am still 100% open to any and all suggestions in the diagnosis of this issue. I may record and place a video on one of the more popular "tube" sites to better show or further explain what's happening and then come back on here to post the link?! Feel free to reply back if it's possible you can help before I'm able to complete that later this evening. And thanks for any and all help in advance to everyone.

[Completed] [Q] Need help rooting my Captivate, which has a busted power key.

So I'm trying to extend this dinosaur's lifespan a bit by installing cyanogenmod, with the added bonus of rooting it being that I can remap my hardware buttons. The issue is that the power/lock button is stuck, and fluctuates between sitting neutral as it would normally (fairly rare), triggering itself every few moments, and equally commonly just staying stuck for the most part so the "shut down/silent/airplane mode" menu pops up at random intervals. I've had to disable the lock function because if it locks itself, there's no guarantee I won't spend an annoying amount of time getting it unlocked again.
The easiest way I've found to fix this I've found is to remove any functionality from the power button, and put its actions onto one of the volume buttons instead, but to do that I need to root it...which is where I'm having issues. I've got Odin up and running, and I have to put my phone into "download" mode. I tried using the key combos on reboot to do this, but due to the busted power button, it just begins power cycling itself as long as I have the volume buttons held. I'm not sure how to get around that. The other option is, apparently, to do the following: "Enable USB debugging, and then- 1: open a command prompt, 2: adb shell, 3: adb reboot download". I'm assuming that once I have the console open, I'm supposed to type "adb shell" and then "adb reboot download", correct? Problem is I have no idea how to get to that point. My google-fu skills are usually pretty good, but I cannot for the life of me figure out how to open a command prompt on an android device. I didn't even know that was a thing. So now I'm stuck, and have decided to ask people more knowledgeable than myself. Can you guys help? :fingers-crossed:

Hi there,
Please see this threads read an follow that procedure for rooting and ask in one of them for more answers:
Rooting the Captivate Glide (SGH-I927)
Rooting the Captivate Glide for an old WM6.1 newbie
Root and unlock Samsung Captivate running Android 2.2
Good luck

Apologies, I don't mean to sound rude because I do appreciate the help, but two of those are for a different phone, and the third had a very brief instruction on rooting that simply said to use a program called "super one click"...which, when run, appears to have tried to root the thing, but locked up in the middle of doing that (didn't brick the phone thankfully) and, annoyingly, installed quite a few adware/scamware programs onto my computer...I've spent the last 3 hours sanitizing the thing. Is there an official guide floating around, or something?
I'm really just trying to find out how the console works at this point. It's not a very search-friendly topic, apparently. I think I've gathered so far that the console I need to be using will actually be on my computer?
edit: nevermind, got it figured out...managed to fiddle with the power button long enough to get into download mode with the button combos. Thanks for the help.
Now I'm off to figure out how the heck I'm supposed to get clockworkmod onto it >_<

found old Samsung S2 Plus, Cyanogenmod Stuck on boot

Hello guys, im a total newbie with android/cyanogenmod/recovery etc. so sry for any dumb mistakes.
I have an old Samsung S2 Plus that a friend of mine installed cyanogenmod and some other stuff on some years ago for me.
I think it was Cyanogenmod 12.1 but im not completely sure.
My problem today is that when i boot the phone i get stuck on some bootscreen (the one with the blue cyanogenmod "alien"). Just nothing happens, had it blinking for 1 hour and more just to test it.
I tried getting into any of these recovery modes (searched online for some key combinations), tried a lot of combinations(volume up + power etc. but no recovery is showing up, just always the white samsung galaxy s2 text and the blue alien thingy afterwards. I think back then my friend installed cwrm recovery mode, but again not 100% sure.
Im thankful for every help and sry again for any dumb questions.

No mistake is a dumb mistake, unless youve already made that mistake several times and you repeat it, expecting the outcome to change. The more you mess something up and you fear youve messed up big time, the more you will figure out a way to fix it and gain knowledge.. embrace it..
On most Samsung phones, you have key combinations that are all the same.. very specific how you do it though..
Im going to use keys below, to simplify things a bit
[H] = home button, bottom center of screen
[P] = power button, usually top right edge
= volume up button
[D] = volume down button
If your phone is in boot loop* or not responding to power button, you will first have to completely restart all the system fresh.
* boot loop: an error that cause a device to start to load and at a certain point restarts, and repeats without ever getting past the point of restart
Two ways I know of to manually do it:
- You can take the battery out, and then press and hold power for 30 seconds. Then release power and insert battery.. leaving it in a dead state.. not powering it on, not charging, or even plugged into laptop..
OR
- Press and hold [D] + [P] *ONLY* for 45 secs or until the phone cuts off, careful to not accidentally restart
Once device is in that dead state, use key combos listed below:
..........☆ RECOVERY MODE ☆..........
press and hold
+ [H] + [P]
when the splash logo* appears,
release all of them
*splash logo: the first thing you see when powering on your device. Usually will say like samsung s2 and powered by android. You usually only see it for a few seconds
..........☆ DOWNLOAD OR ODIN MODE ☆..........
press and hold
[D] + [H] + [P]
when you see a blue screen,
quickly release them all.
then it will have instructions
typically to confirm into download mode,
or [D] to cancel and reboot
Straight Talk phones are known to have these taken out, so you cant free the phone from the grasps they have on it..
If those dont work, and your phone isnt straight talk or verizon, you can download these programs to windows OS pc, and they have buttons that will send a call to your device, and put them into download, fastboot, sideload, adb, or even recovery mode.. not all those modes are available on all samsung devices..
ME PERSONALLY, I HAD MOST LUCK WITH "D P TOOLS" AND "WINDROID"
ODIN IS A MUST HAVE IF YOUR GOING TO BE INSTALLING ROMS. ODIN WILL GET YOU BACK TO BONE STOCK FIRMWARE
Stock firmware can be found on multiple sites and here on XDA. Firmware is device specific and android version specific.
Heres a couple of the latest android versions
6.x.x = marshmallow
7.x.x = nougat
8.x.x = oreo
X/// STOCK FIRMWARE LINKS ///X
you would use the model number which can be found under the battery, and android version. since you may not know which one your running. I suggest google search for " your phone model + release date + release specs" that will get you in the ballpark

**GENERAL TIPS AND TRICKS**
THESE IVE HAD THE MOST LUCK WITH. IM PRETTY SURE THIS IS THE ACTUAL URLS WHERE I DOWNLOADED ALSO.. NOW SOME WORK WITH THIS PHONE BUT NOT THAT PHONE. SOME WILL WORK WHEN ATTEMPTING TO PUT INTO RECOVERY MODE BUT WONT PUT INTO DOWNLOAD MODE.
**USE OF SOFTWARE HINTS AND SUGGESTIONS*
I HIGHLY SUGGEST NOT TO RUN MORE THAN ONE OF THESE PROGRAMS AT ONCE. SOME USE ADB.EXE AND IVE FOUND MULTIPLE ADB.EXE WILL CAUSE SILENT PROBLEMS.. IF YOUR UNSURE HOW MANY INSTANCES OF ADB.EXE ARE RUNNING, CLICK (CTRL) + (ALT) + (DEL) ALL AT ONCE. THEN CLICK TASK MANAGER. ONCE TASK MANAGER IS LOADED, CLICK THE PROCESSES TAB AND FIND ADB.EXE
** USB TRICKS AND SUGGESTIONS **
USE IF POSSIBLE YOUR ORIGINAL USB CABLE AND DONT USE ONE THAT HAS ANY HINT OF A PROBLEM, USUALLY THE THICKER THE WIRE THE FASTER AND SAFER IT IS.. OEM WORK THE BEST.. AND IF AT ALL POSSIBLE, MINIMIZE THE AMOUNT OF USB PORTS BEING USED TO PREFERABLY JUST THE CHARGER WIRE. SOMETIMES USB 2.0 AND USB 3.0 WILL EFFECT THINGS. DO NOT HAVE MORE THAN ONE PHONE CONNECTED AT A TIME.
GO INTO DEVICE MANAGER AND UPDATE USB DEVICE DRIVERS AND MAKE SURE SAMSUNG DRIVERS ARE UP TO DATE
Hope this has helped.. Sometimes the buttons on a phone will quit working but when you press it, it feels like it worked, made the sound and all.. thats when these programs come in handy.. im guessing you charged your phone until it came on, and when you were trying button combos, the phone was still on. It has to be off first. ADB and fastboot are powerful tools if you know some terminal knowledge, you can also start a shell and usually terminal will tell you if deamon* started successfully or not.. sorry about the mass confusion.. go run around XDA forums just searching and reading and now that youve heard me mention some of the lingo and terms used.. Google search everything.. the resources are there, and i just gave you a good bit of direction.. good luck

Samsung J7 Prime (2017) SM-G610Y Boot Looping Problem

Good day, this would be a pretty lengthy post. I'd like to describe my experience clearly since I don't know what I possibly skipped over as I am very positive that my efforts have been correct basing on prior XDA forums. I even made this account solely for posting this to ask for help formally along with archiving this problem I'm having for those having a similar experience.
I've been working on my mom's phone this whole day and there are fruits of my current hard work. I am immensely stressed and despairing with my situation.
The Problems
Infinite boot looping
Can't access the recovery menu (power, volume+, even with home button)
Can access the ODIN / Download menu
Can't turn off either (holding down power button has no effect)
What I've done so far
I read XDA forums about similar experiences. Can't really access the recovery menu so I've factory reset.
We live in the Philippines and this phone is open line, so I went with those requirements while searching stock ROMs.
I downloaded the stock ROMs of the phone model via galaxyfirmware.com which was positively shared in the forums.
Did trial and error with it and eventually got the right one. I have formed a level of understanding with the filenames and eventually knew which is compatible.
Used Odin3 to Flash the BL, AP, CP, CSC, and even go Nand Erase and got the PIT file inside the CSC (Opened it using winrar)
The flashing is actually successful and quite fast to be honest.
The phone reboots itself and shows that it is still sadly boot looping.
Also, despite the several files used for the Flash, still can't access the Recovery Menu.
With that said, I have also tried using Frija which automatically downloaded the stock ROMs based on the model name and CSC type. Placed it in ODIN again and no changes, still boot looping.
I also can't put the TWRP I got here because of the FRP Lock, which can be undone via the settings of the phone. But since it's boot looping, I can't really do much about installing a custom ROM.
Currently, my dad is letting the phone drain its battery, since we can't really turn it off. The phone model doesn't have easily detachable battery as well, unlike the old days.
For some additional notes of what happened prior to this incident
My mom was just playing with her phone as her usual days went on. That day, she installed a new hotel-themed game she saw on Google Play. As I assume that it's from the app itself and not on some shady apk website, I saw no problem with it and didn't think it was the cause of all this. I went with the theory anyway and with the flashing, using CSC instead of HOME_CSC (which apparently saves the existing data on the phone from wiping), and even used the Nand Erase in the end. It's still stuck at boot looping.
I would appreciate anyone's reply to this discussion. I am truly desperate to fix this for my mom. If worse comes to it, I'll save money to buy her a brand-new phone.

You don't have a working android, so you won't remove the RFP. TWRP will not help you with this.
The symptoms you describe indicate a defective power button.
You manage to enter download mode because the power button is constantly on.
Because of the constantly on power button, you have no way to turn off the phone. Bootloop can also be the result of a constantly on power button.
To sum up, you should fix the power button.
1. The easiest way is to blow with compressed air and press the edge of the button with your fingernail, rapidly releasing the pressure. Perhaps the fuzz has blocked the button. Unfortunately, this rarely works.
2. Take the phone to a local service center.

Hi ze7zez! Me and my dad greatly appreciates your insight and we were definitely enlightened on this angle.
We didn't really think that the power button was stucked pressed on because you can clicking sounds when you press on it. The phone never had problems with the buttons along the 6 years it accompanied us, perhaps its age does start to show.
We're going to look into it tomorrow. Thank you very much! You gave us the idea that it may be shorted inside or some sort. Thank you again!

A bit of update.
I pried open only the back case of the phone so I can see and clean up the power button. I used tools specifically for it and made no damage on the phone during the process.
We couldn't really see anything busted from there. The buttons on the circuit still do the neat clicking sounds on it. Battery still looks the same.
Testing out the theory that the power button was stuck on:
We tried to only press and hold the volume down and power button. It didn't go to the download menu. We needed to press down all three together to access it. It is confusing since we believe it would be a power button issue too, as the phone instantly turns on by itself when plugged to a power source (it's completely drained by now and we still can't turn it off manually)
Perhaps it's an internal circuit problem with the power button? It's confusing with the fact we still have to press on it to access the ODIN menu if it was like "on" the entire time it's looping.
Thank you in advance for further insights.

Try restarting by pressing home, power and volume up all at once.

Hi Pranav2406,
I have tried that as well in order to access the Recovery menu to factory reset, but no luck.
We have given up on repairing the phone and went out yesterday to buy a new one in a rush.
We will still send this broken phone to a repairman.
If he fixes it, I'd ask what he did on it so I can post an update on this problem as well.
It's better to let the expert troubleshoot it.
I do suspect the problem in the phone's hardware. I'm pretty confident with all the stock ROM flashing I've done so it's not a software problem.
Thank again for everyone's insights.
Perhaps this case is too much for an amateur to fix.
