Back in June, I turned on my TF700 with the dock attached, it started as usual.. I turned on my wifi, opened up my browser to look up plane tickets, then it restarted. I didn't think much of it, and when it loaded up again, I tried to look up tickets again, and it did the same thing. I gave up, closed it and zipped it up in my sleeve. It was a few hours before I got home, and when I took it out of the sleeve, it was quite warm! It was constantly rebooting and there was no way to turn if off. I left it out of the sleeve and let the battery die. I didn't use my tablet for a few days, and when I went to turn it on again, the same thing happened, and has been happening ever since. I have tried to start the tablet while connected to the dock, the wall charger, without the dock, with wifi on, with wifi off, etc. The tablet gets to the lock screen, I unlock it, and I only have about 10 seconds before it freezes and restarts. I am unable to turn off the device, because when I choose "shut down" from the menu, it shows that it's in the process of slowing down, but then the spinning wheel freezes and it vibrates and restarts before it can fully shut itself off. Since I can boot into android, I thought it was something that the tablet is trying to run upon startup that was causing problems. I was able to quickly get to settings and apps, to uninstall several apps, but nothing has helped. I used to have a task manager widget on the home screen, and uninstalled that too.
After doing research into the problem, I found that most people who have boot loop issues or constant restarting, are rooted and are experiencing difficulties with a new ROM. I am 100% stock. I have held down power and volume down. It gives me RCK, Android and Wipe. I have tried cold booting into android, but the same restart loop after 10 seconds occurs. I thought it might have been a bad firmware update that went through unbeknownst to me. So I downloaded the firmware file from ASUS, renamed and flashed it sucessfully. However, no change in the reboot problem. I am running the following version: US-epad-10.6.1.14.8-20130514. I know there's a new version out, but wasn't sure if I should try to flash that yet.
I am willing to try absolutely anything to fix the problem, with the EXCEPTION of wiping data. I know that would be the easy way to go, but I have photos and videos from my best friend's engagement and they are the only copies. If I am able to get my tablet to be stable enough to copy those off, I would then be willing to wipe and have a fresh start. I have tried connecting my tablet to my computer, and it is recognized. After it boots up and I unlock it, then the tablet begins to mount (I'm on windows 8). However, I still only have 10 seconds or so before the tablet restarts, and that's not enough time to even view the folders from the tablet.
It's been 3 months since this started, and I have done lots of research and tried lots of things, but nothing has helped yet. Since I haven't delved too deeply into the dev side of android (I've only rooted my S3) there is lots of android speak that I don't understand fully, or have experience with, like ADB. If someone is willing to offer suggestions on what to try, I am very good at following directions! Thank you for any help or leads you can offer.
Wow - you're in a difficult situation...
You being on stock I can only imagine the bootloop is caused by something you installed.
So if you can access settings and are able to uninstall apps, just keep doing it until you are back to the original stock setup.
Are you sure the files you are trying to save are still on the SD card? Don't know how you flashed 10.6.1.14.8, but flashing a complete firmware package ususally erases /data - although your persisiting bootloop indicates it didn't...... if the bootloop is caused by an app. And I can't imagine what else would cause it.
You could try to do a factory reset in Backup&Restore but you will loose the contents of your /data partition...
You can flash the 10.6.1.14.10 firmware file, but most likely you will also loose your data.
The only way I can think of to replace your bootloader and firmware without data loss is if you try to find a copy of the 10.6.1.14.10 dlpkgfile. That is the OTA update file Asus pushes out to users. It's a patch file, meaning it only replaces/updates new files and leaves everything else alone.
If you find the dlpkgfile on some forum you would have to place it into your /cache directory and reboot - and I don't know if you can copy it to your tablet before it bootloops again.
Unfortunately the reason for your bootloop is probably an app on the same partiton with the data you don't want to loose. Unless you manage to uninstall the culprit I don't see much hope....
Good luck!

Try getting adb access, this should allow us to diagnose the problem you are experiencing.
Tablet side: go to settings, developer options (if it is not visible, tap the build number 7 times), enable USB debugging
Computer side: no idea, they say Windows 8 is a bit tricky to get the drivers installed correctly.
When you have adb running, do "adb pull /proc/last_kmsg" and post the downloaded file - it should contain valuable info about your reboots.

He's bootlooping..... How does he go into settings and turn on USB debugging?
I think the best option maybe to flash a stock Asus ROM from their site but that will wipe all data including those photos......

I have not use this method but you could try.
You need a boot OS tool on your external sd and run it from your external sd so you can access to your internal sd to copy files from there. You can search on the internet and you should find more information on how to use them depending on what boot os you are using.. Good luck.

I was actually able to get usb debugging turned on. It took me quite a few tries, but I did it!
I've never used adb, but here's what I've done so far.. I downloaded the Android SDK and ASUS Pad PC Suite (which contains Asus Sync).
I was able to use the command prompt to navigate to the platform-tools folder and open adb, however when I type in adb devices, it doesn't recognize my device. What steps to do I take from here to be able to use adb to see my device, so I can pull the file to diagnose what's going on? How do I know if I have the right drivers installed so my computer can see my tablet? All I did was install the asus suite. Do I need to do anything further on that end?

What Windows version do you have on your PC?
You can check your drivers in Device Manager. Open it, look for your tablet under Portable Devices and check if the driver has a yellow exclamation mark next to it. You should be able to update/install/uninstall the driver from here.
Try to find out if there is a setting in your Windows version to only allow Microsoft signed drivers and disable it.

Hey gang - I've been traveling for work and just have some crappy slow satellite wifi for access. The phone has been great because I can use wifi calling and all is good.
A few weeks ago my phone crashed. When I rebooted I was at the "touch android to begin" screen. Well... fix permissions and clear caches didn't work.
So next I restored a backup from CWM.
Unfortunately, after that the phone hangs at the initial Samsung splash screen.
Now, stupid me didn't go an a six-month trip with the Android software on my laptop - so I had to wait for my wife to mail me a thumbdrive that has SOC, HOC, drivers, & etc. on it in order to do anything.
In a previous thread from when this first happened, you all recommended I use HOC to flash the phone back to stock. Which now that (yesterday) I got the thumbdrive in the mail, I am happy to do.
My problem comes from the fact that the phone hangs at the Samsung splash screen seemingly no matter what I do... zadig.exe doesn't recognize the phone on the USB port (just "unknown device") and therefore HOC can't do anything (I think?) Furthermore, I can't even get back into recovery or download mode; at least not with the several techniques I've tried so far.
Recommendations? Or am I hosed?
Thanks in advance,

Interesting problem. I have bricked my phone a bunch of times and have always been able to get back to at least "download Mode". The method I use to go to "Download Mode" is With the usb cable plugged into the computer only, power off the phone. If phone wont power off, or stay powered off, pull battery, then put battery back in. Now hold vol down and vol up buttons only, keep holding these buttons as you plug the usb cable into the phone. In 3 seconds the download screen should appear. I hope this helps you get your phone back.

This sounds like a time where a jig would be helpful. Any chance you can have your wife order one, and send to you? http://www.youtube.com/watch?v=D7I4dFX_iJ4
This should put you straight into download mode, and you can then flash.
Thanks, guys. I continued fiddling and got the phone into DL mode.
I also noted that when plugging and unplugging the phone, it would show up in zadig as "unknown device."
I tried to load the drivers on that, but (a) it still shows up as "unknown device" and (b) when I run HOC it doesn't see the phone under the list of compatible devices.
So.... still kind of stuck.
Any more ideas?
Oop. duplicate post
It's been awhile since I've played with the one clicks, but, "serial gadget" is what I remember seeing when I used them.
Right. MORE messing around later and "Serial Gadget" is it.
That said, I still think I have a driver issue. I have tried uninstalling and reinstalling the zadig-recommended drivers for Serial Gadget several times. I also tried manually installing the drivers from Super One Click.
Anyway, now when I load up HOC I get the green <<connected>> at bottom; but then sometimes it wants me to install the drivers (again) and sometimes it gets past that part, but then goes to
Flashing Kernel: 0%
...hangs there for about 10 seconds and then
Failed!
So... driver thing you think?
Thanks again,
If you reboot the phone after the 0% hanging for 10 seconds, does it go to the yellow exclamation mark screen? If so, just reflash again and you should be back to working... both my and my wife's phone always did that when I had to flash a kernel.
That's just another download screen that theraze is describing.
Exacatly. But the alternate download screen always came up after restarting the phone after a 'failed' flash where it stayed at 0% where it was successfully communicating through the cable. That just meant to not break the drivers or unplug anything... just reboot fast and finish up quickly.
Okay - I can definitely try that! It had not occurred to me to try and reboot the phone right then.
Question, though - when I get the "Failed!" Then HOC essentially hangs, when it says something along the lines of "ending session..." and never progresses from there. So how do you "restart quickly?" Because I have to like, close and reopen HOC. I guess I will see if it succeeds at ending the session when I reboot.
I will try it again. Strange though, sometimes HOC accepts the existing driver (I managed to DL the Samsung driver installer) and sometimes it wants to reinstall "WinUSB." does that make sense? Is the WinUSB an acceptable one?
The winusb is the right driver for heimdall, it doesn't like the Samsung driver.
Sent from my Nexus 5 using XDA Premium 4 mobile app
Samsung drivers and the one click drivers clash. Yes, uninstall Samsung completely if you want to use the one click.
Hm. Thanks for that - might be part of the problem.
Dunno what I did differently, if anything, but last night I tried flashing again and this time it went through! I was very glad to see the whole HOC process completed successfully!
So anyway - thanks so much for the help, guys.
Hi!
I desperately address you today to ask you for help with my Huawei G615 (U9508; 1GB Version so it’s not Honor2/U9508B, but shouldn’t make a difference).
Problems:
- Phone won’t turn on (seems to be a bootloop).
- Phone won’t charge.
- Can’t find many of the needed files for flashing. So I need working mirrors or would appreciate uploads.
History:
Early 2013: Bought, standard Android 4.0.4 version, rooted by myself.
April 2015: Updated/Flashed to official (?) 4.2.2 with EmotionUI 1.6, rooted afterwards. Since then (not sure, maybe it’s unrelated to the update), I had multiple, annoying error messages when Wi-Fi got (re-)connected, but ignored it for months for not finding a solution.
Indeterminate timespan: State of battery charged wasn’t shown correctly, phone shut off too early. Used app “Battery Recalibrator” to fix this, needed some attempts but finally worked.
16th Feb. 2017 (Day X): Accidentally dropped phone (1-meter drop height, good TPU/silicon phone case cushioned it; no visible damage to phone or battery, no software-crash). Phone continued to work normally. Charged it to 100% before sleeping.
X+1: Phone was 99% after waking up, then suddenly 12%, shut down on 10%. Showed 0% afterwards, plugging it in to charge didn’t help. Despite charging it says 0%, powering on (only possible when charger plugged in) leads to bootloop (Huawei Logo, Android Logo, Huawei Logo (because it restarts)). Decided to put the phone on the cool window board over night without charging it.
X+2: Tried again to turn it on, after many attempts it magically turned on. Worked for the whole day, I still tried to flash the phone to get rid of my other Wi-Fi error log problem (and to prevent other possible problems by doing a fresh new start), didn’t seem to work. Charged it to 100%.
X+3 (today): Phone was already powered off when I woke up. Still can’t turn it on.
What I also tried continually:
- Tried charging with different power adapters or directly from USB. Still 0%.
- Tried wiping cache, wiping/factory reset.
- Flashing it to official 4.0.4. and 4.2.2., seemed not to work because it was over after some seconds, but the SDROOT/dload folder is ~1GB (although it said it worked, see spoiler).
Spoiler
When in recovery and choosing “apply update from external storage”, and then “dload” it says it failed to mount /sdcard (E:; “no such file or directory”).
Then error to open /sdcard/dload (“no such file or directory”)
Then
“Install from SD card complete.
cust copying files.
copy cust files succeeded.”
But as I said, that's possibly not true that 1GB gets copied in some seconds.
Status now (as I remember from Day X+2 when it worked):
- 4.2.2
- EmUI 1.6
- Android system recovery <3e>
- USB-debugging should be turned on (not sure) and phone should be rooted (Superuser was still installed after wiping, but it said it needed an update, so it might not fully work).
- Kernel and other software stuff: Can’t remember, can’t turn on the phone. And don’t know what they all mean tbh, I’m glad I know a little about the differences of Android official and custom ROMs and what a recovery is (and that I may need the Chinese recovery for flashing I cannot find online).
Further Details:
I personally don’t think the fall caused my problems because it continued to work for the whole day and the drop was cushioned. What I suspected: It could be an extreme case of the battery charge status problem. The phone thinks the battery is still 0% although it’s not. So it shuts itself off. Or the bootloop is caused by faulty software/ROM, although I didn’t change anything before the problems appeared.
I’ve read through several manuals and now get some sense of the topic, but I still don’t know everything relevant. Also, most of the links to important files are dead.
In addition, a problem I have is that despite reading through lots of threads, they require me to have a working phone, but mine is stuck in a bootloop.
What I want:
A clear, new phone software. Doesn’t matter which Android version or if official or custom ROM. Just want a working phone without the Wi-Fi error, so a fresh new start, a clean flash.
So: How do I do it, and importantly, where can I find the needed files?
(Even though I might buy a new phone next month, I want this one to be fixed so I can gift or sell the phone.)
Software I already have:
HiSuite, HuaWei_USB_Driver.exe, Android SDK, dload-B115 (folder, should be official Android 4.0.4), dload-B703 (folder, should be official Android 4.2.2), cm-10.1-20131006-EternityProject-hwu9508.zip (CyanogenMod 10.1 from Eternity Project); already rescued my data, so I’m ready to wipe.
Software that might be missing:
Chinese recovery, fastboot mod (what for?), CWM (what’s this, what for?), TWRP (what for?).
Many thanks in advance!
EDIT:
As recovery mode (Power + VolumeUp) works and the phone can be on for hours when in this mode (as long as it's plugged in), I assume that it's not the battery but a soft/firmware problem.

The situation is following: For two months the device worked flawlessly. Some time ago, my phone started to randomly hang and reboot. I was unable to find any pattern with these reboots - it could work through an hour of stability test and fail when I was reading a book. Lately, the situation got much worse - the phone may reboot many times right after OS boot up. I thought the problem is with my sd card, but when I removed it, nothing changed. I also tried to update the ROM I use(It was fulmics 2.0, so I flashed 3.0). And I noticed, that reboots may happen even in TWRP(luckily, none happened during the installation of ROM).
The questions are:
1) Is it possible to properly diagnose the cause of the problem? If not, what may be the cause?
2) What to do now? I believe the only possible ways are to replace motherboard or take phone to service(and they essentially will do the same thing - just replace the motherboard)
I think I killed my phone. I lil' story -- i decided to flash my Redmi 9A, flashed PBRP onto it and.. Black screen. I already faced it, so I just try to flash original firmware with SP Flash and... Error. Can't quite remember what it was. I try to use bypass, and although bypass does give the "Success" output, SP Flash still gives the same error. I google this error and it seems like it is an issue with drivers. OK, I remove all the drivers and try again. It got zero battery at this point. Now it's not recognized by PC at all, Windows gives no error, FIlter Wizard doesn't even recognize it, Bypass gives a driver error. I'm sure I installed all the drivers correctly. I also tried:
To use my installation of Arch Linux using this guide, no success, bypass doesn't recognize the phone
This LIveCD, where all the drivers should be properly installed, but no success, same as every other try
I'm very stuck. Any suggestions?

If u install a recovery rom and you did it wrong you can boot to fastboot, no?
Hey I faced similar or even worse (twice), I had a similar story to yours,
FIrst itme:
I first bricked my phone, but it was cool, the phone just flashed MIUI for a fraction of a second when trying to go to recovery, other than that, nothing, I tried flashing, wich made it much much worse, black screen, no key combo did nothing, windows not just did not recognize it,it told me there was no way of recognizing it, (error 43 in devices admin, its not posible to reinstall the driver, nor do crap at this point) filter wizard showed nothing, bypassing imposible, etc.
It got pretty similar to what you had:
I just left the phone do some charging discharging cycles (at least 4 days with me checking if the phone did anything at all almost once every day, just so you know the phone was really bricked) and it eventually responded after all that (Im not quite sure what fixed this, I dont kno if it was complete discharge or what, but something happened and it vibrated when holding the pwr button.
Once that worked, I managed to install the filter by pressing volup voldown and conecting the phone to the USB port (dont use 3.0, it works worse for some reason) at the same time, you need to connect and press the buttons and connect at the same time (
at 1:30 he does it, video on spanish) and then you can install the filter.
Then you can Bypass and attempt to flash with SPflash tool, I recomend autoconcect, UART never made it for me, Im thinking thats for when you can put it in EDL mode by presing the test points, but I dont know enough to say for sure, point is, UART never worked for me, even tho I eve know what comms I was using.
second time:
I was running Custom ROM ArrowOS 12, ArrowOS13 came out some weeks ago, so I decided to lash it, it was better in some areas and worse in others, the contacts app did not work, but now Volte fingerprint(irrelevant to us redmi 9a users) and face unlock did so I decide to test some stuff, I wasnted to flsh boot.img from original MIUI ROM on top of ArrowOS13, to check if that fixed some stuff (that worked wonders on ArrowOS12) that bootloped thephone but it was fixable from recovery, I did that and decided to flash MIUI ROM to check if flashing ArrowOS13 from MIUI ROM worked, and flashing MIUI bricked my phone.
unrecgnized with error 43, not posible to fix from software, black screen no response whatsoever from any key combo (all 7 combos) no charging, no filter, no nothing, I know I had around 50% battery (days ago I remembered the exact number, now I forgot it, but just so you know, its not a hunch, I knew it had battery) I tried doing the same stuppid crap, charging and leaving it alone for couple hours, but after one night nothing worked, so I assumed I would have to repeat the procees I did before (I wrote it complete on an unbricking thread so I knew I could go back there and redo that or variate it until it worked), but I decided to do one final thing.
I knew it had battery, so I decided to try and forcedrain the battery, I took a piece of TP and gave it a turn around the phone over the buttons (this is just to not dirty the phone) then with electrical tape, I left the power button and the vol down button pressed) this for around 7 hours my plan was leaving it like that for a full day, but around 6 hours I thought I heard a vibration from the phone, so I kept it with me, then after a while I thought it happened again, but I also had my own phone with me so I thought it was that and some other things distracted me so Im guessing I missed a few, but after that I started to take time from every vibration and yeah, around every 8 - 10 minutes the phone vibrated
I decided to connect the phone (I hadnt before because it would just slowdown the battery draining process) and the phone conected to the pc, still bricked, but it was a lot better, I quickly installed the filter, wich I dont quite remeber, but it wasnt easy, I had some hickups, cmd bluescreened my PC when using Bypass like 6 times, so I switched to powershell and that worked (to do that you need to press shift+right click and open powershell here, then run "python main.py") that worked, but I did not flash using SP flash tool.
I was trying to avoid turning on the phone for fear it would go back to the previus state, but after a while pluged on the PC it showed the no battery logo so I tried to tun it on and it was bootlooped, I was able to go to recovery and fastboot (not normally, I pressed the keys, the phone try to go into those menus, it showed no battery, and in the next cycle after splash logo no matter what you did it sent you to the previus key combo menu) I tried leaving it charging on fastboot, but that did not work, I tried flahing a rom from recovery (wich said I had 47% battery) and it successfully did but when trying to reboot to system it again showed no battery logo. so I put it on fastboot and tried flashing MIUI with Miflsh, did not work but it told me the ROM was bad (same one I had use before) I made sure to extract it again and again nothing, I assume it was the antirollback, so I downloaded the next one on line 12.5.6.0 (I was on 12.5.4.0) and that finally worked (Miflash actually gave me lots of errors but you can google them and most of them have easy fixes, like creating a log folder, etc)
that was yesterday, after it worked it showed me the phone had around 60% batterywich lasted around 30 minutes to 40%, then it took 10 minutes to spend the next 20% (it told me that) and then it drained 1% every second (Im not exagerating I thought I had fried my battery with all that power button pressing) but I had hopes of it just being a configuration issue of the phone not knowing how much battery it had so I just left it power of and pluged it then so the phone knew what was his zero, now the phone as been on 100% for like 2 hours (sharing internet), so yeah, I think the battery has some issues but its better than nothing so Im happy with that.
that is my whole experience, I hope it helps you, see if you manage to get any response from the phone and if you do you can try contact me for help in any point along the way.
Update, it just got to 99% after 2 hours 10 minutes aprox IDK, I would need to test more to be sure
