Hello people, as I know that there are very intelligent people here on this subject, I would like to ask something.
My head unit stayed in boot loop with the Hyundai symbol and after a while now it doesn't even turn on the screen but the equipment works because although the stations are not heard they move with the physical buttons.
I would like to know if there is any way to be able to reinstall all the firmware of the device again, either by disassembling and wiring or without having to disassemble

Irulu AL101: No Sound, Dicky Auto-Rotate
Greetings.
I had reached a point of near Android-Nirvana with my non-phone 10” off brand (but still pretty nifty) tablet: all of its/my issues had been resolved or accommodated and “we” were actually approaching something akin to productivity. Then, of course, things went bad. Perhaps you can help?
The tablet in question:
Model Number: IRULU AL101
(Currently selling for ~$120 with combo USB keyboard/case & shipping included on ebay, though I bought mine months ago)
Android Version: 4.0.4
Baseband Version: 1.5rc4
Kernel Version: 3.0.8+, Nov 5, 2012
Build Number: crane_al101-eng4.0.4 IMM76D, 20121113 test-keys
The problems:
Auto-Rotate acting oddly.
No sound.
Note: I normally use the tablet in a noisy industrial environment while wearing ear plugs, so I can’t be sure if the sound stopped working the same time the auto-rotate stopped working properly. Earlier this April, I went on a trip and used my tablet as an Internet clock radio, so I KNOW the sound and I THINK the auto-rotate were both working properly then.
The no sound problem is, of course, self explanatory. The auto-rotate problem requires some explanation.
a. When I switch auto-rotate on, auto-rotate switches on. Excellent.
b. When I rotate the tablet, the screen rotates properly. Excellent.
c. If I suspend the tablet (short press on the power switch), the tablet suspend. Excellent.
d. If I turn the tablet back on, the tablet turns on. I am greeted with the tablet locked screen, which rotates properly. Excellent.
e. If I unlock the device, the screen instantly rotates back to the normal landscape position, and the screen will not rotate again. Not excellent.
f. If I inspect the settings, I discover that auto-rotate has become unchecked.
I have done everything a clueless newbie with a computer running a slipshod OS supported by crappie/nonexistent documentation might (e.g., reboot; remove apps; “factory reset”, etc.), but, other than wasting my time and engendering in myself a deep longing for ZDS DOS & CP/M-86, I have accomplished nothing.
Other than taking myself and my tablet to one of Google’s campi and immolating us both in protest, can anyone suggest anything?
Thanks in advance.

Did you ever solve this problem with this tablet? Mine just started doing it. The only other thing I noticed is that the sound will start up if the screen is off, but only once it starts a new music track. Also video playback problems at the same time. I just wondered if you were able to.solve your issue without a factory reset or with a reset. Thankyou for your time.
Dear Bert,
I’m sorry (for both of us), but I never did solve the problem. I went as far as trying to reinitialize the tablet, but the feature that back’s up and restores the firmware (or whatever it’s called) doesn’t work on any Irulu tablet I’ve ever tried (which is two or three).
I eventually just bought another one (and a few spares). I certainly can’t prove anything, but I think installing an app might have corrupted it. I have treated my new tablet like a Windoze computer — i.e., I’ve tried to avoid installing software that can be done without — and thus far all is okay with the replacement unit.
If you have any success, do report back when you have a chance.
Good luck!

Well I have the firmware tools from the board manufacturer, I had recovered this unit from being bricked before. Anyway I loaded a full fresh firmware flash for it formatting the system partition as well. The problem still persists. At the moment my current working theory is power issues internally. For some reason when the screen turns off the sound will return. So I in hooked the backlight and got some static over the speakers. Its almost as if the power is being drained from the sound processor and the tilt sensor causing them to stop functioning. It could also be an issue similar to the trod on xboxes, solder joints under CPU coming undone because of heat. No heatsink or heat spreader on these units. If I can't figure anything else out I may try reflowing the solder. The person this tablet came from lost all paperwork that came with it otherwise I would return it.
If you want recovery mode instructions, firmware and firmware tools let me know. Most of the info I found to help me get that unit back online before was in Chinese. Also Hecate what you do install app wise. These tablets are "rooted" with full system access. Easy to mess up the basic software. These tools should work with all of the irulu tablets. Worst case I do have access to the firmware archive and can get the firmware you might need.
Sorry for rambling here, I have ADHD can you tell.

Dear Bert,
Thanks for the feedback.
At the time this problem appeared, I made some fairly extensive efforts to restore the tablet, which included obtaining the Chinese utility which is supposed to reformat the tablets internal memory and reinstall the operating system. I confess that I can’t recall all the details of what I did, except that my efforts resulted in a broad and impressive variety of failures.
I think I might still have the software/etc. lying about, so I don’t need to avail myself of your very generous offer. Thanks anyway!
Fortunately, other than this issue, I’ve had no trouble with the tablets (the original or its replacement) whatsoever.
Cordially,

Just like many of you, yesterday in the night, i got hit by the dead wifi. When i tried to turn wifi on, it would automaticly turn itself off. In my system info, i didn't have a mac address and after a system restore, it still didn't work. Many users there solved this problem by sending their device back at the manufacturer but since i've got a imported phone from japan, this was not a solution for me. Finally, after many reboots attempts, disconnecting battery and spamming the wifi button a lot, i had to do something else. So i took all the courage i had and opened my phone.
Fortunately, my Fujitsu F-02e was really easy to crack open and i reached the wifi module right after removing the lid. The first thing i noticed by opening the phone was all the dust it had inside even if my phone was Dustproof/waterproof. So i first blowed out all the dust and then rubbed the module a little, trying to find a way to repair my phone. Finally i resigned and put it all back up and then after reboot the wifi worked again!
This is to use only as a reference, to help all of you and people on warranty should NEVER open their phones. I am not responsible for whatever happens if you open your phone and don't guarantee this will solve your problem. Maybe i was just really lucky.
Finally, i'll share you my idea on how this happened. First, my phone is real easy to get hot when on wifi and on gps. And last week, i turned on the dev option keep lit when charging in android dev options so i keep my wifi on and share stuff easily. Then i kept my phone on it's charging station all the day long which might have overheated the device. From now on, i won't ever turn this thing on.
Good luck to all of you having the same issue i'm aware this is a real pain in the ass.
Edit: Also forgot to tell that anybody without experience with phone repairs/disassembly should never attempt opening their own and maybe ask a friend with knowledge instead.
Also i'm ready to help people out opening their F-02e but it isn't hard at all... There is no hidden screws in the phone and i removed 7 including the antenna screw.
Hi guys
My wife brought me this phone from E-BAY and I accept that I have something completely different inside the case (namely something lower spec).
So far (in general) its good enough for my needs, but I have no idea of the hardware spec I have OR the software involved (seller in Hong Kong claimed Kit Kat).
Also, when I recently connected to my car charger the screen went dim so I quickly unplugged it and the phone took over an hour to switch back on afterwards. Since then my home screen and desktop screens have gone haywire and the phone keeps putting itself in silent mode. Phone itself still dials, makes and receives calls but sound us absent everywhere else ie video/mp3 playback. The "home" button no longer appears to work either, like the volume buttons.
Is there a PC program that I can try to plug into to help me establish exactly what I've got under the hood, with a view to downloading a compatible ROM ?
CORRECTION.
Label in back of phone states the model as being SM-G900H.
Apologies for my bad navigating but this phone is my only source of internet.
Many of the controls no longer function as they should do and its difficult to navigate the forum (unfamiliarity) with inconsistent controls. Can anybody point me with tips towards recovery please ?
Can't find the original eBay listing now (of course) but all I can offer is maybe some pics of phone and the label inside if it would help. At THIS moment in time my priority is to find out exactly what my hardware is so I can then try and source a suitable ROM to install, can anyone suggest a PC utility that can "investigate" my hardware (and maybe software) so that I can begin to try and correct what is wrong.
Ok long story short, i threw my phone at the wall and now it wont turn on. Im not too bothered about the phone, ive had it a while and want a new one anyway, however upon removing the micro sd i discovered that all my pics and vids from the last few years are stored on the phone.
As i cant power it on (i get a constant red led if i connect it to anything) i cant see it on the pc to pull data off, anyone have any suggestions for me to get them pics and videos?
I've took it apart but cant see anything obvious to repair, all i can think of now is putting my motherboard into a working z2
The LED is not meant to stay constantly on when connecting the device to something whilst off. It is supposed to go off after a few seconds. That doesn't sound good.
Have you checked to see if you can boot into fastboot mode, or even flash mode? May not help in this case, but if that functionality is working then the device is not dead just yet.
Also, make sure all needed drivers are installed on your computer. The device will not be picked up properly without them. Install them manually if not.
If you can place the motherboard into a working Z2, which will eliminate many potential areas of failure provided it starts working, then that is the only way you can retrieve your data.
It's impossible to retrieve data stored on built-in storage on a dead device, so what you are asking has no straightforward answer.
Next time, please throw significantly cheaper items at walls, and not modern, uncommon smartphones.
last bit is brilliant advice, problem with that is automated services annoy me and the phone is in my hand already when i gotta put up with them lol
I cant get it to power on at all, not fastboot, flash mode nothing.
I know putting the mainboard into a working z2 might not work but i figure thats my best chance, i think it can be done with jtag tools, but not willing to spend a few hundred quid for something ill probably never use again..... I've also seen some eMMC readers available, but as that involves removing the eMMC chip from mainboard id be even more stuck if it didnt work
Good Morning/Afternoon/Evening
Really losing hope with this device as have never got it working in my existence of having it (around 6 months) for some reason have come back to try now as a pretty big waste of money when I actually would have a use for it.
I’ll do as best I can to outline everything I can think of but if anyone has any suggestions they are more than welcome.
The basics of the problem are that when I connect the box via HDMI to my TV it show the Beelink logo, moves onto a please wait animation screen, then boots to the home screen for about 0.5/1 second before signal dies completely (or at least the TV displays no signal) and nothing I do seems to be able to get it back (unplug HDMI and plugging back in (at both TV and box end), cycling extensions on my TV). I have tried around 5 different HDMI leads, 6 different TV’s/Monitors (Samsung/LG TV’s (from UK), a Chinese imported monitor and an ASUS monitor all capable of outputting at least 1080p, TV’s can output in 4K), 3 different power cables but all to the same outcome.
I have flashed different firmware versions with no issue to try rectify the problem but still the exact same thing happens, factory reset the device multiple times (although it isn’t setup anyway due to the input error), if I go into recovery the display holds perfectly, doesn’t cut out at any period of time (essentially could leave it on forever and it wouldn’t cut out as far as testing, leaving around 10 minutes and then moving option as didn’t know if it would go to sleep if I didn’t press anything but this remained on for at least 40 minutes with no issue with display).
I’m lost as to what I need to do to get the box to work and while I am tech savvy enough to get by, wondering if someone far smarter than me has any suggestions of what else the problem could be. As far as my knowledge I would think it was software related due to the screen cutting out but holding/showing recovery or boot animations fine, but could be wrong. Didn’t know if it could be something like the firmware trying to set the display to auto but all my displays not recognising whatever signal it is trying to output?
Hopefully someone might have some idea’s for me to try.
Thanks
