[Q] eLocity just quit...won't boot up

I have been running my a7 with dexter's mod 1.4 for about 1 1/2 weeks...everything has gone well. This afternoon I turned on the device and it failed to complete boot. The word Android would come up and then nothing. I tried to reboot, reset, but device would do neither...nor would it turn off completely. I kept trying to take it into recovery mode and then after several tries was able to wipe, do update again, and get everything back as before. What would cause this and should I look for this to happen again? deepmagic
My a7 was running well for about a week since it quit...but today when I booted up device, it failed to recognize sd card...same card used for updating to mod 1.4...same card I've been using to listen to my music, etc...but now won't recognize...I've tried two different micro sdhc cards..formatted, reformatted, but device continues to display mount sd card...all else works fine! Does anyone have any new ideas? I can't even reinstall mod since a7 can't read my cards. Thanks for any input that would be helpful. I understand these issues are ongoing for many out there...what to do?

Mine has hung on a black screen on me. Seemed that it didn't fully come out of sleep mode.
I was able to recover by holding the power button for 15 seconds to hard power down. No data loss.

Exact same thing happened to me this morning. Tried to reset - not happening. Hard powered down. Don't have time to try anything else right now. I'm new to the forums and new to android. Wish me luck! I've been loving my A7, and much appreciation to Dexter and all the other knowledgeable hackers/modders/posters.

hey the same thing happened 2 me twice. Once the first day after i got it, since i had only had it for 1 day i wiped it reinstalled dexter's mod 1.41 and it worked. First app i installed was backup root. Now, a week later the exact same thing is happening. This time i dont want to wipe it because of all of the apps i have installed, games ive played etc. Any ideas? Could we just try reinstalling dexter's md without wiping? Or wiping reinstalling and recover from a backup?
Also have you installed busybox? I had just installed it both times before it failed to turn on. Maybe its just coincidence but you never know..
-D
Thanks to anyone who can help! and also thanks Dexter for all your hard work as well as everyone else that has contributed to the elocity, im lovin it! (when it works )

success!!!!
I got it to work! I don't have a permanent fix but if it happens again just boot into recovery and reinstall the dexter's mod update 1.41 and it works again! No wiping required. This isn't a permanent fix but it will work until we find one

Hasn't happened to me (yet) but I didn't upgrade to the newest ROM. I'm still using 1.3and it has been very stable. Only issue I've had was when I tried to use Killswitch to go to sleep mode when the cover is shut (great idea) but it didn't work and froze all except the live wallpaper. Weird.
Good luck, guys.

in the event it does happen to you, you might want to check out my apx thread for reflashing the factory firmware if you can't get your tablet unstuck. theres alternatives if you don't want to get stuck again.

The method you outline seems so complex...way above my abilities, but makes me wish I had followed though on some early programming training opportunities. That was the road not travelled.

okantomi; while i wouldn't encourage others to follow thru with procedures they fear would cause more harm, i would mention that if you google up my nick you'll find i've been able to do much w/ android software and devices while not knowing anything about programming. if i can do it, anyone can. i just wanted some themes for my phone.
i'm just an android hobbyist by night (and when i get a chance during the day), and a computer tech by day. no programming expertise, but i can reasonably reverse engineer and port software and components using simple file managers like ztreewin(trialware).
don't be mistaken that the folks out there providing you solutions necessarily know anything about programming or software development. just how to chef up files at different levels. i understand this doesn't go for everybody.

Thanks for the encouragement. I'm impressed with what you've been able to do. It is also nice to read upbeat comments about the A7. There is something sort of special about a device that you really almost have to build yourself... putting so much into it... biting your fingernails to nubs with each ROM flashing. You don't get as attached to any device that is 100 percent complete right out of the box, though of course there would be a lot less aggravation.

[Q] Screen doesn't turn on but wasn't rooted?

So i would say I have a pretty bad problem. Randomly my phone shut off, and when i tried turning it back on, the logo would show up but the screen would later be turned off and only the buttons would light up(home, back, settings, search) THIS IS THE SGH-T959 Model.
I DID NOT root my phone or anything, and the state in which it is in right now i THINK is called a "brick"? My phone randomly keeps vibrating and the buttons stay lit up, but the screen is just completely black. When turned off the battery just keeps refreshing and show a little bit of green, but it doesn't charge past that.
I followed some instructions and I think it's in recovery mode right now, what i see on my screen is Android system recover <3e>. I have the options to choose "reboot system, reinstall packages, delete all user date, delete cache data, and format internal-sd card" I tried rebooting but didn't work, neither did reinstall packages and the error tat came up was E: failed to open mnt/internal_sd/update.zip(No such file or directory). I think that is fine though because i WAS NOT trying to root my phone or anything, this problem just randomly occured. I searched and found things about people getting this problem after rooting, but i didn't try rooting it.
I don't know what to do next, I can't backup any of my content or data since my phone screen won't turn on.
I tried all the common things like taking out the battery, etc, didn't help.
I also read about reverting it back to stock, but my phone is technically already in stock, since all i did were occasional kies updates, nothing that relates to rooting it or flashing it
PLEASE HELP!!!

Does your computer recognize the vibrant when you plug it in?

nope, and when i turn on kies it tells me to connect my mobile phone

And you have data to get it off before we can consider wiping it?

Don't use kies. It will brick your phone. Happens over and over. Use Odin to go back to stock and start over whatever it was you were trying to do.

what do you mean if i have data? If you are asking if i have my data backed up then no I don't.
and I don't even remember the last time I used kies, probably because there are never any updates. And isn't it like the official way of updating your firmware?

In recovery do delete user data and wipe cache if that does not work just reinstall stock rom using odin but go to download mode first. That is pretty much everything that can be done at this point.
If after Odin you still have wired problems in most cases it means water damage and you mother board needs to be cleaned or replaced.

Gun thanks so much, I fixed it after deleting user data and wiping cache. Unfortunately the apps were deleted so it's basically a brand new phone.
THANKS A LOT once again

Was it that simple? Good for you.

Any idea where to find the JFD or JI6 stock Odin images?
All of the links turning up on XDA seem to be dead.
Just picked up this device used for the express purpose of hacking around in it, so would love to have a stock image on hand to restore when needed.

Massive softbrick (haven't found a solution yet)

Hello everyone,
So here's my story: I got a 6P short after release and it's been amazing. After switching from a S6 I couldn't be happier until 3 days ago.
I was playing around with my phone (checking for updates on the play store if I recall correctly) and I was going to switch from 4g to wifi. I went ahead and pulled down my notification shade and went to press WiFi but misclicked and hit Hotspot which was below it. My phone suddenly froze big time and this is for the first time ever since purchase.
At first I thought I'd wait it out since the device was completely unresponsive, home button didn't work and neither did anything on screen. Buttons didn't make a difference either. 10 minutes went by and I ended up force restarting by holding down power + volume up. First part of my bootup went fine but when it got to the android boot animation after I put in my pin to allow the device to start it dropped from the smooth usual framerate down to 1 frame every 10-15 seconds and it slowed down further until it came to a complete halt around the time the android letters appear.
My first thought was corrupt rom so I went ahead and wiped data from the stock recovery. I was running completely stock with no modifications whatsoever. That didn't do anything. Phone still froze in the same boot phase. Desperate I unlocked bootloader to flash a clean fresh image to try to fix it and to my surprise that didn't change a thing.
As I was getting pretty desperate already I had one more idea and that was to flash up to the Dev preview. To my huge surprise it booted and I jumped from excitement. So I started setting up my phone again. I got past the prompt to insert sim card and I was now at the screen to choose a wifi network. As soon as I clicked into that the phone froze up again and at that point I lost all hope.
I wiped data in stock recovery and shut the phone down for the night. On day 3, today I woke up and tried starting the phone and it worked as if nothing had happened. I went through the setup and set up my phone on the N preview. At a certain point I was planning to go back to the latest official build but for now I was happy my phone was back from the dead. Later today I tried to restart my phone to clear all running apps etc and it froze up on boot.
I'm losing all hope that I'll be resolving this myself so I'm reaching out to the community to see if anyone's had this happen to them before and hopefuly for a solution. It's still under warranty so I can eventually send it back to the retailer but I'd rather not have a phone for 3 weeks.
Any and all help is appreciated.
Thank you for reading through my long and probably pretty boring story!

Have you tried flashing the factory image? If yes, did you made sure to wipe/erase the system, boot, vendor, and cache partition before flash the corresponding img files?

To the OP, is there any reason you did not flash to release version 6 instead of Dev preview ?
Also, any reason you can not simply do the "unenroll" from https://www.google.com/android/beta ?
It will require you to setup certain settings again as you will be back to a "factory reset".

DJBhardwaj, i haven't specifically erased those partitions. I was under the impression wipe userdata along with reflashing did that. I will try that tonight when I get home!
Xdafly, I only updated up to N as a last resort because at first I had a locked BL. I was planning to unenrol but that would've been too late as it self bricked after a restart.

Well I just did the erase thingy and my phone booted but wifi won't turn on. Enabling hotspot doesn't brick anymore but I now suspect WiFi might've been the issue. Any tips on how to find out what it could be and possibly fix it?
Edit: 2 restarts and a factory reset later I'm back to bricked same way as before.

try safe mode

That was my first thought, that was the restart that bricked it again. Safe mode shouldn't have made a difference since I hadn't even logged into Google account for apps.

After reading the very first post; sounds like bad WiFi hardware.
All the hanging has been related to WiFi or Hotspot.

I think you should get a replacement

Is your phone rooted and did you install Xposed?
Over the weekend I shutdown my 6p (stock rooted with April security patch, Xposed v80) and charged it. When it turned it back up I kept getting "Unfortunately, nfc service has stopped". Long story short: I ended up factory reset my phone and reinstalled EVERYTHING and I still got into bootloop. Then I came across
https://github.com/rovo89/Xposed/issues/113
https://github.com/rovo89/android_art/issues/28
At the end of the second post rovo89 (developer of Xposed) fixed the bug in V83. I wiped my 6p once more and installed everything with v83. Problem solved.
Good luck!

Stuck in recovery mode loop

Hi guys
i have a custom rom, nougat 7.1 installed and its been working fine. last night i installed an aftermarket battery replacement as the other wasnt holding a charge. after turning on by simply pressing the power switch it went straight to twrp recovery and kept doing so. this morning i cleared the cache and data to start again which was a bit of hassle and it then booted fine. however, i just restarted again and its in the same loop.
i have checked for any obvious obstruction under the rear case that could be pressing against the volume keys but there isnt anything.
any ideas?
cheers

Did you try to reflash everything, e.g. also the ROM?

i didnt really want to do that unless i really had to. as i say, before the battery swap it was fine

But if you cleared already cache *and* data all your data is already lost, e.g. it's like a factory reset. So flashing a new ROM will not worse the situation ...

my Mi Note is dead.

Hi everybody.
Dis morning I woke up and I realized that my phone was gone. I used AOSP Extendend ROM when it happens. At first, the rom completely froze. I thought it was a bug, so I rebooted the phone, but after did dis, the phone kept on rebooting and froze on first screen and I couldn't do anything. Touch didn't respond, nothing worked.
So I tried to go on recovety, but nothing.
At the end, I gave up about take back my data and try to install the stock ROM through MiFlash. I tried different stock ROM, but at the first they works, but during the installation guide they froze again and reboot. I can't even finish the setup!
So I tried again, unlock bootloader, flash TWRP, but still there:
- only TWRP v2.0 works, other versions won't start
- even with TWRP v2.0, after did wipe everything and format, when I tried to install a custom ROM, even TWRP froze and reboot the phone
- TWRP is pretty useless, it keeps on froze and when I boot recovery again, TWRP is locked and I have to format everything again, but still don't work.
Someone could tell me what happened to my phone? Any suggestions about what I could to to install something on my phone?
Pls help me, I am completely lost and disperate

You may in deed have a serious hardware problem.
What you can do without opening it up is to try charging it overnight, and see how it works tomorrow.
You have tried everything else you can think of, I assume, like wiping & formatting everything you can in TWRP, and possibly "repairing file system" if there is such an option.
The next thing I would try is opening it up and disconnecting the battery for a while, then connecting it again to see what happens.

Ok, I will listen your tip. Yeah, I have tried everything but nothing. Technically, I bought this phone last december, so it's still covered by warranty, but I have to send it to China, I would avoid that if I can.
I hoped there would be something that I didn't but...nothing.
Thanks anyway dude
