[Q] [URGENT] Magic Value Mismatch, can someone help me? - G Tablet Q&A, Help & Troubleshooting

Hi,
I am a new android tablet user and I just got my gtablet a few days ago, it was a display model and somehow it's already have CWM on it. I tried to flash the ROM and I ran to an issue. After I re-partition, I got "Magic Value Mismatch" at startup. I don't know what did I do wrong and how can I fix it. But sometime I can get into the recovery menu.
Can someone please give me some direction on how to fix it? That would be greatly appreciated!!!
Thanks a lot!

Go here and do a code red. http://viewsonic-gtablet-for-dummies.webs.com/
Hope it helps.

The link fosser2 posted is the best way to learn about your tablet and also which custom roms work on which bootloader you are running. You will need access to a desktop or laptop computer with known good USB 2.0 connections. The Gtablet will come with a stock Clockwork recovery system on it, but depending on the roms and bootloader I would use the custom recoveries that come with the NVflash files listed in that link. Good luck.

Thanks fosser2 a lot! The site you listed is very helpful!

[Q] Need to flash back to stock recovery coby 7022

Hey guys. Got a problem here. My Coby 7022(which I have read that the hardware is known for problems) will not wake up on sleep after a period of time, so im sending it back to get an exchange. My problem is....I could uninstall superuser, but cannot find out(and ive looked everywhere) how to go back to original recovery.If someone would be kind enough to give me their stock recovery dump and explain how to do it, id greatly appreciate it.
Any help would be appreciated as I need this done ASAP
Thanks,
Zacho56
I am going to "try" to help you.
1) you want to remove Superuser...that is easy. we can do it later.
2) you say you want to go back to stock recovery? are you using CWM now? FDWN or fastoot?
I will be around most of the day today. reply back soon

Download the zip at bottom of post.
move it to your /root directory of your sd card.
make sure you have no other files named"update.zip"(if you do rename it to something else.zip)
change name of downloaded file to "update.zip"
in settings/about phone or about device you should see an option to update. press that. it will install the update.zip to you device.
please report back and let me know if this worked.
more information:
the stock recovery is <3e> your CPU is a telechips tcc8803. I am not sure what you have been using for a search but insted use tcc8803 .

every thing I have provided here is what I think you are asking for. I am unable to test files due to not having the 7022. I am mostly know the 7015....so...use them at your own risk. I will keep digging aaround and post any thing else that i think might help.

[Q] I have a question for a developer regarding recovery

I have just ported CWM for my tablet (Denver-TAC-70051) that is nowhere on the internet, although I hesitate to flash it, I have a question, If I where to screw up the recovery would android still boot up? and another thing, how could I back up my recovery into a .img, my block structure is quite weird, I will attach a screenshot with it, if anyone could help me I would appreciate i, thanks I
Hi, any progress on this? How did it turn out?
I'm thinking about making a ROM for the TAC70051 as well.. No need if you already got one working. Care to share?
PS: I've got the stock-rom from Denver, if you need that I can give you the link!

[Q] Bootloader stuck - PLEASE HELP! - will sell my soul for a fix (to my phone).

Long story short, bootloader is stuck. -- Phone is stuck in a boot-loop of sorts ... it keeps showing the very first screen that shows the Galaxy name and some other info and then flashes that screen over and over again. It is not a boot-loop that loads the OS and keeps loading that continuously. From what I know about phones/programming, which is limited, the bootloader either doesn't exist anymore or the code is not executing properly.
I know there are guides that are similar to my issue, but none of them seem to answer my questions specifically. And when I have attempted some other fixes, nothing happens. I am hoping for a direct answer if anyone has one.
Here's what led to this:
1. I wanted to install the new Android Revolution rom which suggested I have the MJ5 bootloader. I have not attempted to install this rom yet, my issue occurred when I tried to flash the new bootloader.
2. Followed a thread that explained bootloaders and how to install mj5 on note 2 via Odin. --> then got this boot-loop. MD5 and all that jazz was fine. Downloaded from reputable source too.
3. I was/am running a custom rom (JellyBeans build 26 I think) with TWRP recovery. I was previously running CWM recovery, but switched to TWRP because the guide suggested TWRP or Philz recovery for MJ5. Switch between recoveries went just fine. Also, I don't remember what bootloader was installed before I broke it.
I am not a developer (obviously), but I am fairly computer savvy. I can do most things if explained properly. Although I am prone to being an idiot so if someone is feeling a little helpful a step-by-step guide may be best.
I am hoping that someone could (1) provide me with a how-to fix this issue, (2) provide me with a link to the right bootloader that I need to flash in ODIN in order to fix this issue.
PLEASE HELP! I am waiting for some job interview calls this upcoming week and I will be F***ed without my phone. I know it's my fault that the phone is stuck, but I know one of you geniuses here will be able to provide me with some information.
In Summary:
Bootloader is stuck
Phone can get into Download mode, but that's it.
Odin will connect and phone shows up on COM port.
I am an idiot.
I am fine going back to stock recovery/build if necessary to fix this issue.
Thank you all in advance.
P.S. Soul is available upon resolution of the issue; shipping and handling extra ; ) If you don't want my soul I will send you a holiday card with my dogs on it.
You flashed a bootloader for a different phone. Mj5 is for the n7100. The Verizon Note 2 is i605. You have 2 options to get your phone back to 100%. Either use kobols unbrick method found in the general section or send it off to mobiletechvideos and pay them to get it working.

Thank you for the reply, I will try this now. I saw this thread but was hoping I wouldn't have to do this because of its requirements (screwing with the hardware and such).
Like I said, I'm an idiot.
Thank you for the tip though, it is much appreciated.

[Q] Archos 101b Platinum rooting

Greetings, I have a Archos 101b platinum tablet running kitkat and I have been searching around the internet but I just can't seem to find anything about rooting for my tablet.
I would really love to root it and make it possible for apps/games being installed on the SDcard and if possible get an adblock on it. but to do such things I seem to need root access but the amount of information on how to do it for this tablet is so minimal(None) it's driving me crazy.
If anybody is able to help me with this I would really appreciate it.
Extra info:
Android version: 4.2.2
Firmware version: 4.6
Kernel version: 3.3.0
Need Root
Really need helpon this topic guys!
I'm also trying to gain root (even if just temporary) on a 101b platinum, just to remove the google system/app guff.
I assume this is a Generation 10 tablet since it follows "GEN10 TABLETS" in the drop down list for documentation on archos's website.
What I found so far is;
To get to USB debugging you have to press Settings > About > Build, several times to get Developer options, which seems paranoid since ADB alone is nightmare to install and use.
adb root, throws an error about not allowed in production builds.
tried installing the SDE, but it seems the recovery firmware update only accepts ZIP files, so I tried zipping up the AOS file, but the update just errors with "wrong footer".
Tried the Paul/Modoco Gen9 root, but the /data/local folder is locked from user access afaics.
I'm thinking either forcing the SDE on somehow or a firmware mod is the direct solution to root, but I'd ideally like a less destructive version of modding.
Update:
Tried iRoot (formerly vRoot) and Kingo ROOT without any success.
Seems Kingo ROOT goes through known exploits to, I'm suspecting it's been locked down in newer Kitkat.
I doubt a patched firmware will be around until Archos issue a stock one (it's currently missing from the list)
Quick post;
I've noticed a few other people have had the Kingo ROOT crash the boot process on the Archos, and think it's bricked. It's not, if your tablet (or nearly any new consumer electronics) refuses to shutdown for any reason, press and hold the power button until the device powers off. I thought it was common knowledge, but it seems not.
qUE
I have the issue from KingoRoot that everytime I boot up the tablet starts from initial setup so I have to set it up every single time it is switched off.
Rom Archos 101b platinum
Hi guys,
I used king root on this tablet and it completely ruined it, everytime it boots it goes through the initial setup.
Basically i have the file here on my computer that will fix it but i cant find a site to upload it to. If someone can help me out with this i can provide the rom to fix what king root broke .

Accidentally flashed wrong TWRP.

Hi all, I am new to this forum. Please don't mind if this was not the right place/section to start a thread. I was trying to gain more knowledge and trying to fix my tablet. I was looking to install TWRP (as I remember, or it was some bootloader I guess), but unfurtunately my device was not listed. So by looking up at the motherboard sticker and doing some research about the similar tablets on google. I felt that installing a specific version was a good idea. I followed steps listed on a site to flash it into tablet using adb, and by booting it in recovery mode.
It turned out to be a disaster for my tablet, which is now stuck at black screen and won't show anything. If anyone can please help me out to fix it, It would be highly appreciated.
My tablet's name is Waywalkers M9, 10.1 inch. Bought from aliexpress.

Hey,
Do not panic, all you need to do is install the stock firmware for that tablet, then flash it using odin app, and it should work again. You should find the stock firmware on google.
