Bootloop 802L everything is stock and cannot get to recovery. - Huawei MediaPad M2

Hello,
I have an 802L stuck in a Bootloop.
It is stock ROM and NEVER modified, the battery was flat for about 2 weeks, plugged in and got usual charge symbol.
Waited for full charge and turn on and bootloop. Have let battery drain and tried recovery when plugging in.
I cannot get to recovery with any key combo as listed on various sites.
Is is recommended to pull apart and remove/reconnect battery, is there any other way to reset or bin it??
Thanks

It would seem the disconnect is probably the best at the moment. More than likely you never unlocked the bootloader

[Q] so this is my problem

I have a one X unlocked international version which I had rooted and set up a recovery. I then went on to try to flash over ARHD after super wiping, and did a battery stat reset since I had flashed at around 30% and figured it would reset the calibration on the battery. Anyways, from here this is where it goes bad. After restarting it goes into a boot loop and ends up getting kicked back into bootloader. After this I try to factory reset to no avail. After trying to reflash the rom a couple times using recovery, recovery just died and won't even load anymore. In addition to this I can't get the battery to hold a charge as each time I plug it in it reboots and loads then says 0 battery and dies instantly. I can get to bootloader and fastboot but can't flash anything through fastboot because it says the battery is too low.
Any suggestions on how to fix this and get it back up and running, or am I forced to send it to HTC the moment they bring in parts for it. (right now HTC says there is a wait on parts as they do not have any in stock as its a new phone and their texas facility has diddly on hand)
Any suggestions are welcome as to fixing this predicament.

How did you wipe batterystats, from CWM? As the recoveries are new I suppose it's possible something went wrong if you did it that way, but it seems unlikely.
However, though probably not the root of your problem, there's no point in wiping batterystats.bin, as all that file holds in information on what processes have been using battery since your last unplugged your charger. This was one of those android myths (I used to do it too ) that was officially put to bed early in the year:

I'm pretty sure I've seen others with this issue, have a search around the forums. Have you tried turning the phone from the bootloader screen, and leaving it plugged in to charge for a while?
Try this:
1. Boot into bootloader
2. Select Fastboot menu
3. Select "Power off" to shut down the phone
5. Plug in charger
Leave it for a while. From what I've read, the power LED may flash at first, but should settle after a few mins to a solid red. I'd leave it till it's green and fully charged then try again.
If that works, and you can get into recovery again, try restoring your backup of the stock ROM if you have one, to check the phone boots okay. (If you didn't take a backup first, you will next time. ) Otherwise try re-flashing the ROM, or if that fails you might have to re-flash stock recovery, re-lock your bootloader and then run the relevant RUU for your device to flash the stock firmware back. You'll have to unlock and root again in that case.
Good luck, hope it works for you!

[Q] Random Reboot Leads to Bootloop from...

OK all I am sincerely reaching out as I am out of ideas. Here is the situation...
Issue : Last evening, running most recent Liquid Smooth 4.4 (Superb ROM, I don't feel this is really at fault just relevant and thorough), I had been doing some heavy tethering when I picked up my beast and stepped out for a smoke. As I am reading up on moto360's 2 1/2 hour sellout I get a random reboot. Eh, no biggy ... it does happen. (Not often, or at all to speak of in my case just stating.) Right after reboot I hit the power button to make a forced boot cycle and it rebooted again before I pressed anything on screen!
Now SOMETIMES I will boot past the initial "NOTE II" splash (NOT often at all ... usually get reboots, splash hangs, or the phone simply turns off on its own from here) If it does make it past Note II splash it will reboot, hang, or simply turn off from here as well.
Steps Taken: I firstly, attempted a restore... no dice. I attempted a fresh install (TW, SlimRom, and DU) ... no dice dos. OK hmmmm
Now to all mighty ODIN (L900VPUCNE2_L900SPTCNE2_1561791_REV04) .... NO FREAKING DICE!!! WTF?!?!? I additionally attempted MC2_STOCK_with_COUNT_RESET-20130511 ... no bueno!
I still have access to Recovery and Download soooooooo ... I lay down at the mercy of you the community!!!
Thanks in advance and if you need more info PLEASE don't be shy!
Same issue here!!!
After a random reboot, I have the same type issue!
Running an almost stock NE2 rom, random reboot then hanging at the Note2 bootscreen.
Like you, I can access download and PhilZ recovery.
I CANNOT flash through recovery. Errors out.
Odin flashes succeed but on reboot I still hang at the Note2 bootscreen.
My recovery is showing multiple error related to accessing E:, E:/cache, etc.
Are you having that issue as well??
Try this go to samsung-updates.com
search device l900 scroll to the very bottom of the list
download the L900VPUCNE2 zip (this is a pure sprint rom)
flash using ODIN3 v3.09
I have flashed this file many times and it works every time.
Hope this Helps.
Exact same thing
I've been running the latest nightlies of OmniRom. And yesterday, out of the blue, random reset then bootloop. No luck with anything, recovery, odin, etc.
Did Sprint deliberately brick our phones?
I'll try the odin to stock to see if I get any luck there. But if anyone else figures it out, it'd be nice to know the fix. Thanks!
No luck going back to stock. It's dead Jim.
I had a very similar issue. Try booting your phone with it plugged into the wall changer; something given the full 2amps of power. It it'll boot, it's possible your battery is bad.
If my case, my phone would boot loop around the splash screen. on the battery power only. I could go into recovery and download mode with no issues and stay on for hours. If I connected it to, say a PC, it would boot, but would random shut off within five minutes. But if I plugged into the wall charger, it would boot with no problems. Stay on for hours. If I plugged it from the charger, it would immediately shut off and try rebooting which it would just boot loop.
Luckily, the batteries are pretty cheap at $10 to $20 on Amazon. I went with the Anker for $15 to get me by till I get my next phone, which will probably be October; I'm heavily learning towards the Note 4
Replace the battery
I had the exact same issues. I ended up buying a $10 battery on amazon and it solved the problem. I did go through all the flashing, odin to stock, etc. All was pretty good when plugged in to a good power source. It took me about 4 hours of trial, error, reflashing, etc before I realized it was probably a battery issue. The new battery has solved the problem.

When I try to power the phone on while plugged to the charger. I see the battery graphic with a circle on it but the phone won't boot at all.
When the random reboot happened the phone WAS plugged into the charger and fully charged. Prior my problem, battery life had been excellent.
Do the batteries go bad instantly?

I couldn't flash any of counter reset rom through anything but TWP so i have to boot into download and update away from Philz. AFTER the recovery update I started making headway. but couldn't ever seem to make it past boot no matter how much batter is charged. I was beginning to think it was something that died on the inside (heh...heh)
After reading through some of these greatly appreciated replies I am going to plug her up to the wall and try the ne2 counter reset again(12:58 am). ... AND I may go throw some cash at a battery juuuuuust in case. (I do tether 100gigs daily sooooooo it does make sense that it could have burnted up lmao!)
UPDATE 1:25AM : I did as advised and it does seem battery has taken a dive! hmmm so weird! It still shows having power and charging. But after being plugged into wall I made it booted into a fresh ODIN install!!! (keep in mind that AS SOON AS odin gave me a pass I switched to Wall outlet!) I have even performed a power cycle to confirm it wasn't a fluke! I will indeed be out first thing in the morn to get a new battery!
AGAIN I can not thank you all enough ... I would have never thought of that. (you would think it would be one of the first things but eh you live and learn.)
I will update with any new progress!
cheers!

'When the random reboot happened the phone WAS plugged into the charger and fully charged. Prior my problem, battery life had been excellent.' EXACT CIRCUMSTANCES AS I SIR!!!
Mine does the same and hangs .... right? HIt the power button and as soon as it lights up to start to boot then plug in the power cable. (the freezing while off and charging is a known bug in at least two roms i believe)
Congrats Rubledub!
As for me, I'm still screwed. Invested $40 in a battery (had to have it today, couldn't wait on shipping)
With the new battery fully charged I still have the same result!

There were probably signs of the battery going bad, but misread. But in my experience, it went to total crap instantly.
The signs of going bad were shorter battery life, getting stuck/freezing when trying to charge the phone when off (there's that battery graphic that shows up). Unfortunately, I did all kids of other stuff before I really figured it out, and looks like a messed up my modem and now cannot connect to 3G. Kind of irritating, but luckily, I spend 75% of my time in LTE areas. Just got to ride this out till the Note 4 is released.
Here is thread of when I was having trouble: linky/URL]. It's a lot of me trying slightly different things with no changes in results. Plus, I was a buddy's house who was in a 3G only area. The worse part, my phone did this the day before I left to spend the weekend five hundred miles away from home at a friend's house to visit.

Oh i agree! Thats is what had me so baffled ... Not even the odin installs were breathing life, and Odin ALWAYS works for me. If Odin isnt getting it done and neither is a battery then your problem may be far more serious???
Weird Recovery Lag and bootlooping after CM12 update
Hey guys,
I came across this thread and the issues I'm having sound so what similar, so I thought you might be able to help.
I have two Samsung Note 2(l900) and running on cm12 as of yesterday morning. I installed the new nightly manually on both devices the same exact way by opening clockwork recovery and installing zip. One device was successful and is working just fine, the other seemed to flash fine until it had finished loading the apps and going into boot. The device would restart on the note 2 logo screen and then proceed to the cm12 boot screen and then restart after a few seconds. I went back into recovery which took longer than usual, and proceeded to clear partition, wipe dalvik cache, and install older nightlies. I had the same result no matter what nightly I went with.
I decided to set the device back to stock rom and root again. I it worked just fine, so I went through the process about 4 times installing different nightlies but had the same restarting results. It was then I noticed that getting in clockwork recovery manually lagged about 30 seconds. I took the advice of someone on the Google plus forum and switched the recovery from clockwork to twrp. Tried again with the same restarting results and with the manual recovery lagging about 30 seconds to get into.
I'm back on stock rom and the device is working great but takes forever to get into manual recovery which I believe is why it is having issues booting Cm 12

Pointers please - what bootloop is this and what to do?

Hi, my 5X got itself into a bootloop state I have no knowledge of and I would really appreciate some pointers.
I searched the forum but I'm still not sure what I'm looking at and more importantly what to do about it. My main concern is not losing my data on the device.
Short summary: unlocked bootloader and rooted, bootloops, difficult to power off, factory images flash successfully but still only bootloader boots. The phone is on the latest stock Android 8.1 and was rooted with Magisk. In the meantime I've reflashed all factory images except userdata with no luck.
Bootloops: the phone started bootlooping by itself overnight. It was on the charger for a top-up and running only a sleep monitoring app like any other night. It boots as far as the Google logo, pauses a bit and repeats.
Power off: if I leave the charger cable connected the phone powers off from the bootloader menu only as far as the charging display and then starts bootlooping. If I first disconnect the charger it does power off, but as soon as I reconnect the charger the phone turns on and starts bootlooping.
Reflashing doesn't help: all factory images reflash successfully but the phone still won't boot into anything other than the bootloader. Booting into either the standard recovery or TWRP goes straight into the same bootloop. FWIW I also obtained the latest cache image and erased and flashed that but no luck.
My main concern is not losing my data so I want to be careful with whatever I try next.
I'd be really grateful for some pointers on what I'm dealing with and what the options are, thanks.

Phone won't boot up or charge

Hello there Beautiful People,
Yesterday i tried to root one of my former phone as a test if i could root current one cause im interested in it, it was my first to root, i was able to unlock oem and everything after i tried to flash the magisk image i accidentally wrote it to the system partition instead of boot one and i was stuck in a boot loop, i figured that too after booting into Recovery Mode and after that i went for the "Power Off" mode and after that my phone stopped booting and charging, i just wonder if there's anything i could do with it or its now completely dead forever. Thank You for your time.
UPDATE: i was able to bring it back to life after 5 hours of suffering.
Try changing the battery outside the phone on a stand-alone charger or in another phone.

Question Battery dead during boot loop

Help! I just got this phone and wanted to root it, so started flashing using Odin, couldn't flash because it turned out I had a slightly different firmware causing the phone to be stuck in a boot loop, with download mode and recovery mode still accesible.
Now that I have the right firmware, I can't actually flash it because the battery seems to have died during the boot loop while I was downloading the right files.
It has been on the charger for about 45 minutes now and nothing changes, no response on buttons, no battery indicator, nothing.
Would be really glad with any tips to at least get it to charge so I can boot to download mode and flash?
Also, trying to root probably triggered the knox bit, so that means all waranty is void right?
Edit: it seems to be in EDL-mode, any tips on what to do to restore the phone?
Did you solve your problem ?
Let charge your phone at least for an hour from an electrical outlet (not from computer).
