Error [302] : Update error

During a ROM flash yesterday I got a STOP unsigned driver message. I clicked continue but I've ended up with a persistent ERROR [302] : UPDATE ERROR message.
At first I thought I'd bricked my phone. No matter what I did or I couldn't sort it and I even tried a search here on XDA but couldn't find anything useful that worked.However I'm lucky enough to have more than one PC so I simply flashed the phone on another PC.
This worked first time so I've now successfully flashed the phone. I'm posting here as it my help someone else in a similar situation. I still haven't found out why ROM update utilities no longer work on my main PC but I'll get to the bottom of it when I've more time.

I had the same problem too and thought that my phone is bricked. It wasn't a good feeling at all right?

[Q] Bricked Kross GY-601 Chinese Tablet

Hi, I have a Kross GY-601 Tablet... One of the cheap chinese tablet you can pickup at factorydirect (Canada)
I seem to have bricked it when attempting to port Clockwork Mod Recovery to it. It does not show anything on screen or do anything, When I connect it to my computer.. It shows up as M6-CHIP in Device Manager as shown in my image.
The internal storage is completly gone as a result of my failed attempt to un-brick it..
It would be a great help if someone helped me fix this..
Thanks in advance..

PS: I'm only 13 sorry if my description of the problem is a bit bad..

Sooo,
You probably don't have proper drivers, use PDANet ones, they work even with obscure tablets.
You tried to port CWM or flash?
It's not bricked since your computer detects it
Last thing, do you have a backup recovery image or another recovery image that works so you can get it back up?
Daniel

I was dumb enough not to do any recovery image backups..
Also.. I ported cwm then flashed it with dd just poped the .img into the recovery block.. but since I didn't compile it properly when I adb reboot recovery.. It got into a boot loop.. so I tried to fix it but broke it even more... So then I tried re-writing the firmware for generic 4.1.2 chinese tablet.. but that messed it up to the point were it only shows as M6-CHIP.. i can only turn on and off.. nothing else.. no boot no screen light up nothing..

I can help you BUT....

I had a problem with my phone recently, then my cousin did some stuff. he said, he replaced the file called "Core.jar" with the same file but from the stock rom, I guess he rooted it, then I couldn't install any Apps anymore or even APKs so I tried to do a hard reset, with great luck, It always gets stucked on "Updating Apps 1 of 134" blah blah, searched some forums for in about 5 hours, I tried side loading some zips(Stock Rom), even a root zip to try fixing, but to no luck. I couldn't manage to get it to Devices when inputting ADB Devices in mini-sdk, only up to sideloading. I really need help

First ask your cousin to fix it again.
If he is not willing and/or able to fix it, then register on xda and ask in the Questions and Answers forum.
Unfortunately there is no specific forum for your exact device/model on xda.
Usually after flashing a complete stock firmware and factory resetting, you should get the phone booting into system again.
Good luck !

sorry
I forgot to login before the question..

So yeah, my cousin tried to fix it. But to no avail. He failed to do so...
as I have tried.. using adb sideload commands it failed.
1st attempt : I tried flashing through adb sideload. Send complete but in my phone, "Installation aborted"
2nd attempt: adb shell... error:closed... tried to killserver and srart again.. tried almost all adb commands.. no success..
3rd attempt: SP flasher unfortunately idk why my device cant get detected like "(serial) devices" I can only detect it when I actiate sideload which goes "(serial) sideload)
I can boot up my phone, but when it starts, it stucks at "Android is upgrading" optimizing apps 1 of 134... I think the cause was core.jar ever since he replaced it. I was not able to install any apks.. what's the function of core.jar anyways?

(Sorry kinda new to this kind of stuff, I was only good at psp models cfw)

As I don't know your device, I can't say.
From the name it is a java file containing core functions.
Best to ask in the Q&A forum I linked in my previous post.
Thanks for your understanding. Thread closed.

[Completed] Help Fixing Bricked Rockchip Tablet

I have a Proscan PLT7650G tablet it came installed with Android 5.1.1. It is running a RK3126 SoC. I had rooted it with Kingroot and then switched to SuperSU. I then tried to install Xposed framework for Lollipop using the Flashify app. The tablet rebooted and when I got to the login screen it had a message box "Stresstest for 5.0 has stopped running". When I hit OK another comes up that says "The process com.android.phone has stopped running". I hit OK and the previous message box comes up. This continues for as long as I keep pressing OK. Sometimes it also says that the System UI has stopped running. I cannot access any of the OS. I eventually tried to run the factory reset from recovery, and the same issue persisted. I assume this is because of the system partition being modified. I have backups of all the partitions made using the Rockchip Android tool. I tried to flash the tablet with the tool and it says Test device fail, or download fail. I have also tried to flash with Rockchip batch tool with firmware I thought may be compatible, and it gave me a similar message.
I didn't install custom recovery, but I can still access stock recovery, and can still get to the error messages after boot. I don't have USB development enabled, and fastboot doesn't recognize my bootloader.
Any help you can recommend will be extremely appreciated. I have spent the past week trying to get this thing running. I am very sorry if there is a similar thread posted somewhere or if it is a stupidly easy fix. I also apologize if this is posted in the wrong spot. I am new to forums in general.
I have very limited internet access, so it may take me several days to respond to any posts.
A HUGE thanks to anyone who can help me.

i can also get clockwork mode but i just have error closed... i installed all the drivers i was able to found but no one fixed the "error closed" when using sideload, also i don't know WHERE IS THE STOCK ROM...
I have this www needrom com download chuwi-vi8-dual-os
"file is too big" so i format in NTFS but then the tablet won't recognize it, and seems like it's the WINDOWS ROM i don't need the WINDOWS ROM I JUST NEED THE STOCK ANDROID ROM
i've been trying to fix this since MONTHS, tried yesterday, it took my whole day today and yesterday STILL NOTHING.
i reposted this here beacause i think i wasn't in the good category sorry i'm new
IF someone can REALLY HELP ME, do i'll have to PAY SOMEONE to fix my tablet ??? Like really, i already posted this in december no one answered me...
