[Need Help] Bootloop after changing font {Solved} - M.O.J.O. General

Grrr I going to cry
Ok guys so i change the font using an app and after reboot the device get stuck at bootanimation.
The problem is that i can't have acces to system partition so i'm afraid my mojo is softbrick....
i try to update the device using fastboot command (c:/sdk/fastboot update c:/mojo.zip) but i got the "waiting for device" even when it is pluged
Do you have any idea of what i can do to revert the android ttf to stock ??
[Edit] Ok i have to thanks again Paul OBrien for his root method because i simply edit is own boot.img by adding in the superboot folder the stock font and addind line to the script to put it in the right folder and set correct permissions. I go into fastboot, flash reboot and it's finaly repair
AH AH AH AH AH AH AH AH AH

[Edit] i think if someone could make a system.img with just the stock font in it or the stock system.img i should probably able to flash it

Idk. Maybe try rooting it and see if you can get it to boot. It's very easy to root if you haven't done so already.

I know reading in one of the other threads in the mojo general forum that someone took theirs apart and there is 3 buttons inside. You might see if you can locate that thread on how to disassemble it and try holding down on a button while plugging it in. There is no known documentation on what they do but if your bricked what could it hurt.

I think rooting it voids the warranty?? which is why I don't get how MC can advertise instructions on their website.
You should raise a support request with them on their site.
Hopefully kitkat is around soon.
Good luck!

We've decided to take an open stance on rooting - it's your box to do with as you wish. Of course the obvious caveats apply that you run the risk of causing boot issues, as Dead-neM has found!
Dead-neM in the interests of sharing, could you detail exactly what changes you made to the script and exactly what you did so it's explicitly spelled out for anyone else who runs into the same issue?

Yeah, how do you mount the superboot.img and modify the contents?

Ok this what i have do exactly hope it can be helpfull so:
1/ Have cygwin + Android kitchen tool on your pc ( This software is use to decompile the boot.img and it can be find into xda forum ) So open it decompile the boot.img of Paul Obrien MmM3 ( Kitchen can't decompile boot if it have not system.img too so i decompile first the 110ww official zip rom and replace the boot img by the Paul Obrien's )
2/Go onto the folder of the decompile Boot.img : So open /boot.img-ramdisk/superboot/ there is a superboot.sh script open it
You can see all command. What you have to do is to put yours before the 3 last line ( mount -o ro, remount -t ext4 ........)
I type { cat /superboot/Clockopia.ttf>/system/fonts/Clockopia.ttf
cat /superboot/Roboto-Regular.ttf>/system/fonts/Roboto-Regular.ttf
chmod 777 /system/fonts/clockopia.ttf
chmod 777 /system/fonts/Roboto-Regular }
cat is used to move file and chmod to set permission
3/ Now i said to the boot img to replace file and set permission to it i need to put the file into the boot.img folder so i just copy the Clockopia and Roboto font into superboot folder
4/Now you can recompile the boot img using kitchen then flash it using Paul Obrien script
Enjoy i think you can put gapps with this method so if there is a courageous one here your welcome !!

take everything that is in exploits.zip and move it to your android sdk directory specifically the location of adb.exe (will either be in platform-tools or tools) as for the two RUUs, they can be anywhere but you will have to move them at one point to your SD card. That is about it

Just do the following and upload your image.

How would one of these get me back to stock? I've got a corrupt file - so I am bootlooping after root. SU causes a seg fault, so I can't get root permission to remount & replace the busted files... anyone figure out getting to recovery yet?

Use this file http://db.tt/3hqvgP1 and push it to /data/local/tmp
Then run it via ./data/local/tmp/gb
You should be root afterwards and be able to fix permissions etc

borked system/bin us version 16gb
hi I borked my acer. root went smoothly, but then I made mistake of trying to enable adhoc supplicant. I downloaded es explorer and used remount to enable rewrite to system/bin. Now everything disappeared. It will still load, but wifi shows error.
How do I return to stock?

Thank you so much! I got stuck on the Android ! boot screen and couldn't get the OS to boot after stupidly screwing up permissions after I rooted. I downloaded your zip, renamed it to update.zip and loaded it on a microsd card. Then I put the card in, booted the tablet while holding volume down and recovery loaded the system image and I'm back in business. It did come with a few apps loaded into system I'm not familiar with including a few that weren't in English. Will a factory reset remove those, does anyone know?
Edit: This is also missing gapps including the market... You sure this is a US image?
no thats a chinese update u need to follow a link thats been post above urs a bit ago and follow the directions on how to add market to the nook color.

Could you explain how to put back a system.img backup in the tablet in case of a problem ?

USA 1.141.07 update fix with. .img's

Crsdr37 said:
Alright Guys in the USA. I will be posting the .img files to fix your device or update your device to 1.141.07 if you have either used the chinese update fix or some other various fix that left you with a different boot image. The instructions are simple.
1. Connect your tablet to the computer via USB. Put the boot.img and the system.img on your SD Card. Also put the Update.zip then use a file explorer to move the update.zip to the root of your SD card. Which is external SD. If you use Astro. (Alternatively you can just take your SD card out and put it in your computer to put the update.zip.)
2. You need to first push the boot.img
-Open ADB type su then hit enter. (your device will prompt for superuser you must select allow) Then enter the command below.
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p2 (hit Enter)
3. Then push the system.img
dd if=/sdcard/system.img of=/dev/block/mmcblk0p3
4. Force shutdown your device when those finish (as your screen may not turn on.)Then hold volume - and the power button "until the green android comes up very important do not let them go just because the device turns on" to start the update.zip. Let it finish (Your device will reboot when it completes.
5. Enjoy the fact your device is back to stock and you can now update when future updates release.
To push the files you will need adb shell. If you dont know what that is look it up, It is part of the android development kit. Second these 2 commands will push the files to their proper mount block. You must push the boot.img first then the system.img These files are for the USA update 1.141.07

http://www.mediafire.com/?3qahjh3twi6jc9t -Boot.img -MD5-4477d6739dd1e3b3ba1dbf94be7fe8f0
Here are 2 Mirrors To download the boot.img you will need to download both as the uploader made it a 2 part file making it easier for some countries to download. Give thanks yo ardatdat if these came in handy.

** Alright guys I am just posting this link for when you just do the update.zip because you are already on 1.104.05_COM_GEN1 and you have a different kernel then the update.zip, What will happen is when you reboot the tablet from just doing the update.zip you may have WIFI error. These files should resolve that issue. Once again they are only if you have WIFI Error on reboot. To install these you will need some type of file explorer that has rw access to the file system. I rec. Root Explorer. To install these follow these instructions.
1. Copy both modules to your SD card does not matter where.
2. With your File Explorer/Manager Copy both of these files. (Root Explorer will let you multi-select if you hit the menu button.)
3. Navigate to System/Lib/Modules.
4. **This step is very important- You must Mount your System for RW access. If you don't they will not copy. Once you have RW just hit the paste button and then reboot your device.
5. **This step is for anyone still having wifi error after reboot. (Stop being lazy lol and just do all the steps. From the top by mounting the boot.img and system.img that way your device is 100% stock there for no checksum issues.

Success! This worked like a charm! I didn't have to use the recovery img I just used the update.zip.
After update:
Kernel: g9b3ce2b

Good work and thanks!
edit: Actually I guess I do have one issue right now. After the update my wifi stopped working. When I go to the wifi settings I see "Error" under Wi-Fi and the check box is grayed out so that it can't be clicked. Any help?
Had a German 1.112 build i guess, bricked it and revocered it with Acer_A500_1.122.01_EMEA_GEN5. Used boot and system image and then updated and it really works!!! Thank you very very very much!!!
EDIT1: I even not lost my settings and can set the language to German too!!
EDIT2: Root gone (as expected), used Gingerbreak (tab version) and everything works fine.

well the only thing I can think of it either the lib modules for wifi are messed up in which case I can post a link with them or the kernel is different. I would use the 2 .img that I posted then use the update zip. That way the images replace your kernel which is always the root cause of wifi errors.
here is a link to the wifi lib modules. You need to use something like root explorer. To mount the system as rw. Then navigate to system/lib/modules and copy those two files into there with the system mounted as rw. Reboot and see if it fixes the issue!!

You get that only when do don't do all three'. Once you reboot after pushing the 2 images. You have to hold down the volume - and the power button it will then run the update zip to complete.

i checked this folder through my phone(i used Astro file manager) and there were 4 bootanimation but with different names so i think thats if i move my custom one there will be a confusion....
plz go to that folder so you can understand what i'm talking about..
There shoul be one simple zip - bootanimation.zip
BTW when you start your phone do the bootanimations shuffle or you get just one
UPDATE
I tried pushing though adb a bootanimation to /system/media but it told me "failed to copy" and thats "Read only file system"
So in conclusion i think i must be rooted to do these kind of stuff...

Geezz... mad for advice
calm down dude.... if you're using root explorer or simillar apps, ofcourse it won't show up... lol :laugh:
use adb to push that files into /data/local/*. it should be mounted as read-write by default ( thought )
i'm sorry if i wrong, i never use Un-Rooted Android devices for more than 3 hours, except my tablet for work ( it's never touched by adb thingy )...
i'm outta here................ good luck for ya

Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks

Hi everyone. As I found out there's root for the G4 but doing this isn't easy especially if your variant is hard to find or has less users. This may result in you waiting for longer than you should. This thread is for those who can take things into their own hands and do it themselves. The tools are available everywhere but I'll give you the best order and steps. I'm using the China LG G4 H818 Dual SIM variant but this method is UNIVERSAL FOR ALL LG G4s.
The process will involve extracting a system image, injecting root and reflashing this image. Most of the steps are effortless and need just copy and paste with keen eyes. Do it slowly. You need an Ubuntu installation for step 2 of this 3-step tutorial. I used universal USB installer and put in on my 8GB USB. Anywhere will do so far as it boots&works. Beware this thread is not dumb-proof but this will not wipe your data or void your warranty if done successfully.
Step 1 -> Getting the proper system image.
Check here and skip to step 3 if you have your rootedsystem.img
>Don't worry because this doesn't require searching. It is from your device. Every device has a system partition and this method will pull it out as an image without root required.
1--Make sure all drivers are installed properly. I'll not be talking about this. We're on XDA not kindergarten.
2--Download the LG_root file or send command file from here and extract it. US Carrier specific check here
3--Put your device in download mode and connect it to your PC.
4--Open(double-click duh) port.bat and make sure to write down the number after com. There maybe different com numbers but choose the com on the DIAG1 line and write down that number. This is important.
5--Hold shift and right-click in any empty space in the extracted folder. Choose open command windows here.
6-- In that copy and paste this
Code:
[FONT=Lucida Console][COLOR=#ff8c00]Send_Command.exe \\.\COM[/COLOR][COLOR=#00ff00][*insert your number here][/COLOR][/FONT]
7--Now you're in send command mode. Nothing looks different on your phone but that's ok. It should just remain in download mode.
8-- On the computer screen in the window you now see #.
9--Now in this post copy the Backup system to internal storage command specific to your device model number. Check in you settings >general >about if in doubt. This is the most important step. Copy the whole line of code. Highlight with your mouse, select everything on the line and copy.
10--You didn't come all this way to fail so do it. Remember it is device model specific.
11-- Paste it in the command window and hit enter. It should take a while so wait until you see#reappear.
12--Now typeLEAVEall in capital letters. Your device will reboot. Check using the file manager if you have a file called system.img in your internal storage. If yes step 2 is next and you did well. If no repeat it and follow the steps properly. Make sure drivers are installed especially windows 10/8/8.1 users. Check device manager
Step 2 -> Root injection.
1--Prepare your Ubuntu USB or virtual machine or computer.
2--Download inject_root zip from here and extract.
3--Copy the system.img from your phone to the extracted inject_root folder on your PC.
4-Reboot into Ubuntu.
5--Here open a terminal.
6--Gain root access on Ubuntu by typing or copy and paste sudo -i
7--You should either be asked for your password which you have to enter or if you used a USB drive like me you'll see the name change to[email protected]
8--Navigate to the inject_root folder by using cd commands. This can also be done by typing cd then [space] then dragging and dropping the folder into the terminal and hitting enter.
9--You'll now see the name in the terminal become longer with the name of the folder in it.
10--Now type chmod +x autoroot.sh
11--Hit enter then sudo ./autoroot.sh
12--If you get any thing like command not recognized or something of the sort use sudo sh autoroot.sh
-That worked for me.
13--If you're successful the name of the file should change from system.img torootedsystem.img
-Please note don't rename the files. Leave them as they are.
14--Now go back to Windows let's finish this.
Step 3 ->Root
1--Transfer the rootedsytem.img to your phones internal storage.
2--Put your phone in download mode and connect it to your PC.
3--Get into send command mode as in step one.
-Put your device in download mode and connect it to your PC.
-Open port.bat and make sure to write down the number after com. There maybe different com numbers but choose the one that has DIAG1 on the same line as it. Note it down this is important.
-Hold shift and right click in any empty space in the extracted folder. Choose open command windows here.
- In that copy and paste this
Send_Command.exe \\.\COM[*insert your number here]
-Now you're in send command mode. Nothing looks different on your phone but it's find. It should just remain in download mode.
4-Now grab your command to flash system.img line of code from this post. It isn't the same as step one. Copy that an paste in the command window. Make sure it is for your device. They are model specific.
5--This should take a while so wait until you see the # again.
6--After thatLEAVEand upon reboot you should have root.
To Un-root just flash a KDZ file compatible with your device here.

Fantastic. This method will also ease devs for future rooted firmwares. I really cannot see LG being able to patch this, since this is basically a 3rd party LG Flashing tool. If they block this method, then their own tool will ultimately die with it.

This is a good method, thanks for writing this up.
I would like to add a few points....
I recommend you do keep your original system.img on your phones regular internal storage. If you encounter any boot issues you can then re-enter download mode and write the original system.img over the top of the failed root attempt. Use the same command from "step 3: root" but replace rootedsystem.img with system.img. This should still be on your phone from step 1 and will recover your phone from a failed root injection attempt. Note that it will not recover your phone if you messed up the dd command and overwrote other partitons. Be sure to use the right dd command and cut n paste to prevent seek/offset typeos.
I also recommend that you keep a backup of your system.img on your pc. When you run autoroot.sh in step 2 the copy on your pc will be renamed and patched. I suggest copying system.img somewhere else first, or re-copy it off your phone.
Additional credits to blog.lvu.kr. This is the blog of the hobbyist who reverse engineered the download mode protocol, created send_command.exe and gave it to the world. Kudos to you.
How is this any easier than the original method....if anything this requires even more work

Oh nice! I wasn't adventurous enough to try it. I'll make a system backup and give it a whirl!
Very nice thread, thank you. The steps were short, few, and fairly concise.
I was waiting for something like this where I could modify my own image and I wouldn't have to wipe everything or replace it with a new image.
One thing you might want to mention is that if your phone is encrypted, you'll need to unencrypt it first.
Can anyone link me to some instructions on how to disable OTA updates for an unlocked/international H815T?

This is what XDA is all about. It tells you how to inject root into your OWN system image. it's the opposite of spoon feeding. it's about teaching members how to do things for themselves. Too many people come here expecting to be spoon fed and have thigns done for them. This thread teaches people how to do their own work, while learning something at the same time.
Good work OP! :good:

Thanks. I guess people don't know what XDA is about. Seeing noobs and others trying to spit on hard work when I used my time and device as Guinea pig. Also people don't know this is almost brick-proof because the system image if from their devices. Unless they use wrong commands but all here is just copy and paste. They see lot's of text and get cold feet. Anyways will be updating the OP with system images. If yours is available please share. If you see your image available and you have drivers and LG_root downloaded proceed to step 3.
The only downside is that I have to drag out my windows laptop instead of doing everything on the ubuntu machine I use at work.
But if that's the biggest of my problems then I don't really have a problem
hi, thx for this tutorial, looks good
when flashing back the rooted img,does it wipe everything ? apps, data ... etc
thx
EDIT: just correct me if im wrong
using this method WILL NOT wipe everything on my device cause im rooting my system with everything on it

How to calculator extractly bs/seek/count ?
Is there a possibility of any personal data being written to /system on a phone during normal use? I can provide 10c Optus AU (carrier 505-02) if I can be sure its not identifying, but ive been using the phone a couple of weeks.

I would also like to know this. You can resolve system by running the following. Note that this is for the H815T and is not the same on all variants.
# ls -lZ /dev/block/bootdevice/by-name/system
You'll get something like:
lrwxrwxrwx root root ubject_r:block_device:s0 system -> /dev/block/mmcblk0p47
Which tells you the actual block device (partition its on).
And you can see the size of that with:
# cat /proc/partitions
where you see:
major minor #blocks name
<snip>
259 15 4239360 mmcblk0p47
<snip>
However I dont know how to identify how large a block is or how to calculate the start offset in the main partition.
ok, it worked great
wasnt easy, since im not so familiar with using ubuntu, but all is ok
the explanation of the how to... was great and nothing lost
my H815L is now rooted
thx guys

I know it's kind of going off topic, but I figured I'd mention that Flash Fire doesn't work on VS986. It just goes to a black screen and sits there forever. I left it sit for almost an hour. I saw elsewhere it has something to do with automount, I'll have to mess with it further.

Appreciated but you should include a way to unroot (undo) as well, ie how do we get back to stock (if required) ?
