[Q] Goclever R75 (7500) - boot freeze (bootloop ? )

Hello. After factory reset my goclever does not stand up. It freezes at android logo and nothing happens later (no reset, just android logo). I think it might be because after installing apex pro i deleted stock launcher. Device manager sees it as ' Full AOSP on Rk29sdk ' (but cannot copy anything to device) and ADB sees no device.
Is there any way to do something ? Christmas are soon, so i will not send it to service cenrte.

Goclever hasn't published any R75 firmware yet. Also this tablet doesn't have any physical buttons except power switch. On my native language forum was sometime ago rumor that on downside motherboard is switch which combination with power button gives recovery menu. Personally i tried various combinations but didn't worked for me.

Any ideas ?

Hello.
Which version of the device do you have?
7500
or R75
Those seems to be the same but are different.
I have stock android version for both
for 7500 - original, unrooted ( from a Russian site - don't remember)
for R75 - original, rooted ( a dump created by me from my device when I have received it)
Both works, were tested by me on my R75.
The firmware of 7500 flashed on R75 works, but you won't be able to use the capacitive buttons (as I told you are different).
The flash option is very simple:
1. Copy two files on the root of the sd card
2. Insert the card in the card slot of the device.
3. The flashing process will continue automatically.
Just tell me which one you need and a place where to upload the needed firmware. I can do the upload this weekend.
Regarding ADB, hmm... this is strange. I have done the same thing as you (deleted the launcher and restore to default) but adb was working with device in the android logo state.
I'm using Windows 8 and I have installed the device as test ADB device (from windows drivers).
Bye.
Edit:
This is the link for R75 rooted firmware.

Edit:
This is the link for GoClever tab 7500

Bye.

On the back he have written that he's tab 7500. Soon i will try to flash him with your 7500 image. Hope it will work ^^ Thank you very much.

Everything on first look is working on. Except wifi card, which doesn't turning on.
/update
R75 software fixed it. Don't trust manufacturer anymore.

hello
this may help some one later
to get into recovery if your R75 table wont boot you have to take it apart the button is on the underside of the board behind the screen (silly place to put it) i have being talking to goclever support and more firmwares are going to be added to the site. if you want yours adding send them an email requesting it (one may not be enough ) i have just had this problem and after a month they agreed to take it back and have reflashed it for me
hope this helps someone

[POLL] Dead EMMC

Hello.
I'm trying to centralize all the EMMC issues in order to see if there's a common link. Feel free to post some details as well after you answer the poll.

There are 2 different common links
1) faulty emmc
2) idiots

I'm trying to see if there's for example a given toolkit that would corrupt your emmc - could help the noobs who brick their phone after using who know what toolkit. We all know that no matter how many times we warn people , some will still use rootkits and AIO toolkits - best we can do is keep them away from the really damaging ones.

You'll never narrow it down.

In the last week we had 4 bricked EMMCs . Out of those there's
- unknown (http://forum.xda-developers.com/google-nexus-5/help/bootloop-nexus-5-problem-persist-t2962356 )
- Toolkit/Rootkit http://forum.xda-developers.com/goo...ed-nexus-5-t2522020/post51345473#post51345473
-Possible rootkit , TWRP 2.6.4.3 http://forum.xda-developers.com/google-nexus-5/help/nexus-5-32gb-mobile-internal-memory-t2969559
- unknown , http://forum.xda-developers.com/google-nexus-5/help/accidentally-bricked-nexus-t2967493
I'm pretty sure if we collect more data - maybe some logs and logcats as well we might be able to find out if there's a specific chain of events that will brick them , bad quality emmcs or just abuse .
Also , I want to see if the 16gb version is less prone to it than the 32gb. From what I dug in the forums it does seem so - though it might be only my subjective impression since I didn't centralize any data yet.

My point is, even if a user was using a toolkit at the time of nand failure, there is no way on earth you van categorically say that the failure was caused by the toolkit. Yes, people shouldn't use toolkits as they don't know what they're doing, but also let's not also attribute faulty hardware, stupid people or just bad luck to toolkits too.
I'm sorry, but this thread won't help anyone.

My problem with emmc brick started when lg sent me back the phone that is still broken.
Before this, my device was only in bootloop at the google logo.

nexus 5 emmc chip problem
I baught a new nexus 5 after upgrading to lollipop Automatically its gone dead but when i downgrade to kit kat mobile was on but not upgrading to lollipop and imei was unknown ,baseband unknown and storage was corrupt and nothing is working only wifi is working
I show this to software guys but they are saying that the emmc chip Is not working is their any solution for it

Fastboot is done from the bootloader itself, it is not a menu option. Step by step guides are in general > sticky roll-up

Ugh guys I'm having the same issues my tablet won't go pass Samsung Galaxy note 10.1 splash screen and can't stay on twrp recovery with out rebooting again.

Hi guys!
same here! my note was charging and I've found it stucked in samsung logo without any reason. I've tried to install almost every version available of stock rom also from different country but no way. I can install also custom recovery but unfortunately I don't have any custom rom to try to install in my sd card. At the current time I really thinking to move to new note 10.1 2014...I'm afraid is some kinda hardware malfunctions. Any update from you guys with same issue?

Wow now I'm really start to think it is a Samsung and hardware issue I think these tablets weren't made to be usable for more than 2 years smh is anyone else with this issue running lollipop roms? Jc

The same here, My friend just conntect me, that SAMSUNG does not want to cover charges, due to bootloader says SYSTEM STATUS: custom.
And he never did anything with his tablet.
He got angry and Samsung check the hardware and they find that some chip is broken. But still don't want to fix it due to custom issue.

Check this link out Root and install TWRP
Then try googling for custom ROMs or just get the stock ROM itself and reflash it.
The problem you are facing is called bootloop. Is it booting to safe mode? Try checking that out too.

Doing anything is (almost) impossible without TWRP. Is there no version that supports yours? If none, you might just have 2 options : get a new phone or Develop them yourself(Takes time but that's a lot of fun, frustration and fear combined when done for the first time). Which one do you choose?

Or wait a sec, is your phone powered by mediatek? And is it booting to recovery? If yes, attach an image of the recovery.

Question Lenovo P11 pro Bootloop Stuck

Hello everybody,
I have a bootloop issue with a Lenovo P11 Pro. It is stuck in a bootloop and keeps restarting 1 min after Lenovo logo.
I have tried anything from Hard Reset to Rescue Smart Assistant Flashing and Qfil Flashing. It flashes successful but Tablet still doesn't want to boot up.
Have any ideas? I bought it like that so don't know what the person before me did to it.
Tablet seems to charge.
Thanks in advance for all the ideas!

I haven't had this situation, but what firmware have you tried flashing? Have you read the threads about the region codes, and how the firmware has to match them (in the latest firmwares) or the region code has to be changed. I would try flashing an international firmware, and if that doesn't work try a china firmware. There are only two regions I think, so one of those should work.
I could have got the wrong end of the stick with this as I've not been in this situation, so not very carefully read those threads yet, so just a suggestion!

I didn't think I had to, when I plug in the tablet it pops up with the name and everything.

Hi, I have the same issue with a Tab 11 pro gen 2. Could you let me know how to solve it? I can't even find the recovery, and tried all button combinations. I can only go to fastboot or meta modes.

im literally stuck on this ( fastboot ) screen... it boots straight to this screen. If i plug the device into my pc it says device not recognised and none of the drivers seem to work. I have tried everything to shut it down so i can try flash via EDL, but the power button just takes me back to fastboot again...

I'm having the same reboot issue 1 minute or less after fully booting. I have no idea how to fix it
