Lenovo A820 won't start - Android Q&A, Help & Troubleshooting

Hello everyone!
I have a Lenovo a820 with Lambda rom 2.4v.
I'm using it for a couple of weeks now with this last version, and everything was fine, until suddenly it froze for a while, I unplugged the battery and plugged it again, and what I notice was that the phone restored itself to when after I installed the rom (meaning all of the apps were gone).
So I tried going into Google play, installing some apps back, and I get this error -24 telling me its unable to install the app, happened with any app I tried. so after trying a few suggestions from the internet about this error, I decided to format it and install the rom all over again.
I go back to recovery mode with CWM, try to install the lambda rom like I did before, and in the middle of the installation it reboots and gets stuck in the "lenovo" screen like when you boot it. so after waiting for a long time I unplugged and plugged the battery again, went through the procedure again this time it installed it 100% rebooted so it would boot with the mod, and again, it freezes at "lenovo" start screen unable to boot.
went on recovery mode, formatted system, data, emmc, everything... I think that's the issue here. but im not sure.
After that, tried to install again with the same problem.
The problem now is. it won't even start I press the on/off button to start it normally, and I dont even get the "lenovo" screen, I tried going into recovery mode and no luck.
It's like the phone is dead! Although I have another Lenovo A820 and I tried the battery, and its 60% so that's not the battery.
Do you guys know any tricks? or any tools that I could use to get my phone running again?
I would appreciate it very much, any help you can give.
Matt.

Stuck on LG Logo for Second Time

Hi People, im using a Custom Rom from Noejm.
Two Days ago, i charged my LG P500 with it turned Off. When i wake up, i turned it on, and the Phone just got Stuck on the LG Logo Screen.
I entered in Custom Recovery and Flashed the Rom again. Installed all the Apps etc etc.
So at the end of the day the Battery was minimal and i turned the phone off again and put it in the Charger.
Today i woke up, turned th phone on, and im Stuck at the LG Logo.
What may be causing this?
do a complete wipe before flashing and frmat sd card after keeping a backup then flash hope vrthythng will be fine than,if u dnt want to wipe ur mmc than just wipe all other option in custom recovery and then flash dont install any application fr sm ours and let it settle down properly
Reflash, Re-Wipe...
If after above it still fails, try to do complete wipe again, and then
flash this from recovery http://forum.xda-developers.com/showpost.php?p=11785758&postcount=557
it will make sure to remove the /system
then reflash your rom
I think i know what happened.
I've installed the last Busybox to xbin. And in that day, that happened.
When i flashed the rom again, i've installed again the last Busybox.
This time i have not installed the last one. Lets see if the problem gets resolved.

Can't get into recovery/download mode..constant rebooting...power button problem?

I tried updating my ROM (to CM11) and came across so many issues. For some reason, it kept rebooting and then at one point just got stuck at the animation screen. So I decided to just start everything from scratch again.
I tried to get into download mode to install CWM, but the phone kept shutting off as soon as I got in. After MANY tries, I finally got in and got it installed. When it finally worked, I tried to get into recovery mode and the same thing happened. Finally after many tries I was able to get in there too. I then installed my ROM and then when it finally loaded, the phone then shut off and tried rebooting but wouldn't get passed the animation screen again.
I did a lot of research and found that some people had their internal power button either get stuck or become defective. Mine clicks so I don't know if that's the problem, but the symptoms that others have mentioned have all happened to me.
Does this in fact sound like a button issue to anyone? Any help is appreciated.

Seems like your hardware button could be broken, I would all do in this order:
Download Philz Touch Recovery from here: https://goo.im/devs/philz_touch/CWM_Advanced_Edition/i9300/
Official Firmware from here: http://www.sammobile.com/firmwares/3/?download=28378
Flash Philz touch through Odin
Reboot to Recovery, selct "Clean to install a new rom"
Wipe cache and dalvik cache
Go to downoad mode and flash the md5.tar file through odin

[Q] Stuck in bootloop and recovery vanished

Ok, so something seems to have gone very wrong with flashing my phone :S
I managed to get recovery working yesterday, and followed the steps in this thread, http://forum.xda-developers.com/xperia-z2/general/4-4-4-creating-rooted-update-package-t2933155 , to create a pre-rooted 5.0.2 image. I put it on the external SD card, booted into recovery and installed the flashable zip, then used flashtool to flash with the instructions (though I also cleared Appslog, Cache and Data to get a fresh install). This went fine and everything appeared to be ok. I then tried to get the Xposed Alpha installed, but after that whenever the phone was rebooting it just hung if trying to boot to Android. I tried re-flashing with Flashtool, but still got the same issue. Would boot fine the first time, but then any restart it would just hang and crash out. Tried clearing the cache from recovery, but no difference.
So today, I went into recovery, re-installed the flashable.zip, then powered off the phone and flashed using flashtool, just as I had yesterday. Now though, my phone wont boot. It shows the Sony logo, then a blank screen, then restarts. Even worse, it will no longer boot into recovery. I hold the volume down button when the LED shows, nothing. I try holding the volume down button all the way through several bootloops, nothing.
I've tried to re-flash using flashtool which goes through the process ok, I can hold the volume down button and connect the cable once its in the process of rebooting, and it goes through all the process fine. It then powers off as expected and I can just disconnect and power on the phone. But it's still stuck in the bootloop and I don't have TWRP recovery.
Is there anything I can do to get my Z2 working?
Update - Re ran flashtool, this time not excluding system, only Partition. It now gets a little further, going to "Powered by Android" and giving the purple wavy lines, but after a minute or so it just hangs and restarts again. And still no recovery sadly....
I think I've got it sorted...
Used Flashboot again to do a flash, excluding System and Partition. This time the phone does boot up normally. The downside being that my root was gone. Despite my flashing a pre-rooted image, it seemed to just put a stock image on. And my recovery is still mysteriously gone.
In the end, just to get things completely back to a stable/stock starting point for later on, I ran a repair from PC Companion. Seems I was in the none rooted position anyway so figured I'd get myself to a more certain position. At least this way I can wait for someone to come up with a root for 5.0.2 so I can root and get recovery back.

Nearly softbricked my S6 edge, f.... up from time to time

Hi
Rooted my S6, and threw TWRP recovery on, put a "sixperience S7" rom on it, at first it worked flawlessly, but since I didnt make a factory reset i pulled one later, thats when my problems started.
Installs fine, reboots and the initial start and setup goes fine, but when the screen turns off and i wake it up again, the screen looked like a pc screen with no gfx driver, funky colors and very dark - tried two times to make a clean install, same happened
Tried to install stock rom with Odin, failed, tried 3-4 times, fails
Then i went into TWRP and deleted all......but seriously all......coudnt boot into anything then, not even download mode, got the message on the screen that "something went wrong in updating the firmware, try the emergency recovery with Samsung Smart Switch" That of course couldnt connect to the phone, when i finally got it to be recognized by the computer, my phone wasn't supported by the program (because it is rooted i read somewhere)
After an hour with a lot of swearing and crying almost, I tried to connect it to Odin and i got connected, installed a new TWRP and i got it into recovery where i could install a new rom, and the phone booted again
Heres my question, when i put it into download mode (tried to install stock rom with Odin once more) then I cannot boot it again, I have to install TWRP and a new rom before I can get it up and running again, is there any possibility to get a stock rom installed ever again?

Oppo R9s plus restarting

Hi guys, i need help.
was using my phone this morning and suddenly it restarted itself.
the phone passed through boot icon and went to "almost" into launcher screen.
my phone is rooted and thought that it might be due to software, hence i flashed stock firmware into it.
so now it is in stock rom and stock recovery.
but the phone still restarts.
it will still pass through the boot icon and since it is fresh installed, it goes to the setup screen, but from the the phone restarts again.
it seems like it restarts everytime it finish boot.
thinking that it might be screen issue, so i go into (stock)recovery mode, i try to navigate around in it by going to wipe phone, install from storage, and the phone doesnt restart.
please advise what might be the cause or issue since i had already flashed stock rom, so i guess rom isnt a problem, and phone doesnt restart when it is in recovery mode...
