Help! Sero 7 Pro Won't Boot - Hisense Sero 7 Pro Questions & Answers

So here's the deal. Yesterday after being at work all day, I came home and unlocked my tablet. A bunch of errors popped up right away about the launcher crashing and a few other things. I powered it down and turned it back on...and that's as far as I got. Every time I try to boot it gets stuck on the boot logo. I was able to boot into ClockworkMod Recovery mode and flashed xboxexpert's custom rom...but still no luck. The stupid thing won't boot and I'm out of ideas. Any help would be much appreciated. Thanks in advance!

Bump? I need help here guys.

My friend's tablet wouldn't boot he opened the back cover unplugged the battery and used a universal charger on it for a few hours then when he tried it again it worked. Although he wasn't rooted and on stock firmware. Have you tried holding down the power and volume up for a few minutes?

It charges just fine. And yes, I have tried that. Nothing seems to work...I'm stumped.

Try hold the power button for 1 min
reply if it worked or not

Not sure what that would accomplish. Did it anyway tho and nothing happened...just started to boot up then turned back off.

Did you try going into recovery mode by holding Power and volume up at the same time until recovery mode pops up?
in recovery mode use volume up/down to scroll and power to select just select "Reboot Now"

How to get into Recovery- Please help

I just flashed this 2.01.605.0- Basic Debloat ROM. There's an error when I click the phone and an error when I try to get on to markplace. How do I get back to recovery? I don't have ROM manager and I cant get to marketplace to download. Realized the hold power and vol down only works on bamf. Please help.
try holding vol up and powering up at the same time.
Also, does your rom have the reboot into recovery when you try to power down and select restart?
Hold power+volume down is how you get to hboot. It is not rom specific. So boot your phone holding Power and Volume Down then select Recovery in the list you are presented with and hit Power.
Also make sure you don't have fast boot enabled, if you do pull the battery then power+volume down. If all else fails "adb reboot recovery" will get you there from adb.

[Q] galaxy tab2 10.1 wont enter download mode

I have new galaxy tab 10.1 which I am planning to root, however I cannot get unit to enter download mode. I have tried unsuccessfully at least 20 times using the recommended method of turning the unit completely off then holding the vol-/power buttons. I press the vol- slightly ahead of the power button and hold. All I get is the samsung splash looping over and over with no download or recovery menu icons popping up after the samsung splash. Once I let go, the tab will go into android recovery mode with the option to reboot which takes me to where I started. I have followed all of the tutorials to the tee. Is there another way to get to download mode? Should I take it back if this indicates a more serious problem.
I have also done a factory wipe/reset to no avail. Will vol+ / power do anything?
thanks for your interest I would appreciate any help.

I seem to recall that at least one variant swapped the button around. In any case, it can't hurt to try volume up.
Here's what you do - first, shut the device off by holding power down and waiting for the confirmation.
Then, when it's off, hold the volume down button (to the left side, next to the power button.) Holding that down, press and hold the power button. When you see it light up, release the power button but continue to hold volume down until you see the recovery/download icons.
If doing that doesn't work, try volume up and power. Good luck!
Ill try your suggestions. thank you

I'm having a similar problem. I have a galaxy tab 10.1 wifi that I rooted immediately when I got it. I havn't used it in about 4-5 months. I've already done all the odin and download stuff, but now i want to update my cwm and install a JB rom (I'm currently using aokp). I'm having a funny problem with it now -- Its difficult to turn on and impossible to get into download mode.
In order to turn on my tab, I have to hold down the power, connect the charging cable and get the download screen to turn on, then hold down the power again, wait for the screen to turn off, unplug the power and hold the power button until hopefully it turns on again. And this doesn't always work, sometimes I have to do it a few times. But whenever i've tried do the same thing that gets the tab working normally -- only holding the down volume as well as the power, Nothing happens.
Now once its on and working, things work great, but turning it on is a pain and its impossible for me to bring up the download or recovery option.
I've also tried to 'reboot to bootloader' and that doesn't work, although i can still 'reboot to recovery'
Any tips?

I have almost the exact same problem...
Volume up puts me into download mode and i can connect with Kies but it wont do the JB update
Voulume down ... nothing just boots
if i let it try to do the OTA update it will freeze at the boot screen and stay that way till the battery dies.
To get it to work again i have to do almost exactly what was decribe above..
I have no recovery options at all.
also my Tab is "NOT" rooted

I had a similar problem initially... the screen would just flash the "downloading" message, but the tablet wouldn't mount/connect to my laptop. Here's the solution:
1) launch odin
2) connect usb cable to laptop only
3) power down tablet
4) hold down the power volume down buttons together
5) when you see the downloading message, let go of the power button
6) let go of the volume down button (now just displays "downloading" message, but nothing happens
7) press volume UP
8) you'll get a message about installing custom ROMs and be given the option to do so by pressing volume UP again
9) the tablet mounts and connects to odin
10) from there follow the instructions for flashing recovery via odin (i.e., using PDA button...)
FYI just double check the guides again regarding download and recovery modes. In the thread title you mention Tab 2. This is the forum for the original Tab not the Tab 2. Both devices have different methods and key presses to access the various modes.

Can't get into TWRP recovery from boot

I'm a bit of a noob at terminology and android settings so try to bear with me...
I'm running a deodexed vzw CleanRom v1.6.5 and I've downloaded TWRP recovery via gooManager. (Yes I've installed the recovery script from it.) Back when I had a stock rom, when I held the power + the volume up button it would go into TWRP recovery fine. But now (I don't know if it's CleanRom's fault) when I start up the phone into recovery mode using the shortcut the blue text would appear but it would restart normally.
My stock backup was corrupted for some reason and it softbricked my phone so I had to odin flash and go through all that rooting process again before restoring from my CleanRom backup via TWRP. So I don't really want to go back to stock, but I guess I can download a stock one if I really need to.
I can still enter TWRP by going into gooManager and pressing reboot recovery from there. Any solution to this?
I'm also on CleanRom 1.6.5 and it works for me... Vol up+power

To get mine to boot to recovery while phone is off I have to hold volume + and menu key at the same time. Then hit the power button until it vibrates then let go of the power button. If I keep holding the power button then the blue writing is displayed but instead of going into recovery it just reboots. However if I only hit the power button and release when it vibrates and I am still holding the volume + and menu key then it will boot to twrp recovery.
Alright, I'm feeling pretty foolish.
It was a simple user error that I really hate to admit. If I hold down the volume up and the power button and keep holding down both, the phone restarts as normal. But I should be letting go of the power button when the phone vibrates, while holding down the volume up button keeps it loading into the recovery mode. Don't know why I didn't have that problem before. I attempted Travis' idea first then experimented a little without the menu button and it worked fine.
Thanks.
Glad you got it figured out. :good:

True and that is what he said he has been doing. However what if you flash something and you get a boot loop. You can pull the battery and try again but if it boot loops again you will need to be able to get to your recovery with a non booting phone. That is why it is important to know how to boot the phone into recovery with out the need of any apps.

Precisely my thought process. I knew that at some time I'm bound to softbrick my phone again and I needed to boot recovery from startup.

Strange bootloop

I have a H900 and something weird happened. I've been rooted for a few months now with no real problems. Was listening to music the other day then my phone randomly restarted and got stuck in a bootloop. First thing I did was flash the root tot again but still stuck in a loop. Then I flashed the stock at&t tot and still the same problem. I'm not sure what to do.
Very strange
After flashing both .tot you have restored all partitions so should eliminate the issue
Try removing sdcard and sim, only things that stayed the same after flash
If this doesn't help (which is unlikely) then you may be toast... ?

Take out battery then put it in. Press POWER + VOL DOWN buttons. When you see LG logo release the POWER button (while still holding VOL DOWN) and press POWER button again.
You should see a screen which is asking you if you want to factory reset your phone.

Thought you were talking about something else. Already tried that and I'm still stuck.

stuck on fastboot & safe mode (unlocked bootloader)

so after installing the latest twrp using twrp app; I tried to boot into recovery and my phone is just stuck on fastboot. I'm not able to turn phone off. Tried different solutions but nothing seems to help. the only command to work is reboot booloader which takes me to the same screen. after searching these threads I have not found anyone with this phone having that issue. any help would be appreciated.
fyi tried 3 different cables, 2 different computers lol.
I discovered that if you hold Volume + and Power while on any screen until it turns off and on and off and on and off again, you can boot in to recovery. (Before I had to take apart the phone and remove the battery lol) Just hold these two buttons for about 25 seconds and eventually it will boot in to twrp/stock recovery
Easier way I think.. .. . Hold power and volume up buttons until end of the second vibration, then release power. After you see the recovery screen - then you can release volume up.

battery finally drained. I tried the volume down + power, released when it vibrates but doesn't get me to recovery. I'm gonna charge it for about 2 minutes and try it again. at least I don't have to worry about this damn thing exploding and setting my place on fire while I'm gone lol.
update: so I tried again and as soon as plug the phone to charge it goes in to fastboot. tried volume down and power. release when it vibrates and it wont get to recovery. I also found a stock file somewhere b322 or 320. put it on a dload folder and did the 3 button trick and nothing either. time to trash this damn thing I guess lol.
Volume UP + power - go back and read my last post carefully for how to get to recovery.

so ok, I tried volume up + power and nothing. phone is on fastboot wont turn off. it restarts but wont stay off.
From your PC folder where you should have a copy of fastboot.exe and put a copy TWRP.img file for the phone:
> fastboot boot TWRP.img
Then if that works, you should be able to turn it off from the TWRP menu - and maybe you need to reflash TWRP if you have not done so yet.

My friend was just stuck at the fastboot screen for hours now and he gave up. I grabbed the phone and held all the buttons, vol up + down + power and when it vibrated I let go of the volume buttons and kept the power till the logo came up then let go and it booted up normally. Not sure why after hrs of trying to figure it out that this worked and I never read to do that. Just wanted to share in case anyone has a phone stuck. I flashed different versions of twrp an could not get into recovery at all.
I just put my phone in fastboot/bootloader mode, then held the power button in until the phone vibrated, then released the power button - after that the phone booted up to normal mode.

Oh ok good to know. Maybe me holding the volumes buttons did nothing so I had basically did what you did since I did let go of the power button right after.
Seems that way, and it's easy enough for you to confirm his phone works the same way just to be sure.
