[Q] WiFi dead - how to fix it? - Asus Transformer TF700

Hi, I have TF700T with Asus stock ROM 10.6.1.14.8 rooted with MotoChopper.
It worked fine for months after root, but lately had become very slow, so I thought about using different ROM.
My intention was to unlock bootloader, install TWRP and use CROMI-X but BEFORE THAT, I performed backup on external SD card, removed it and performed a factory reset, just to start with a fresh situation.
On reboot the WiFi does not activate anymore
I have tried 3 factory resets already but nothing, WiFi does not work
I do not trust to go on with unlock and other things, if the WiFi is KO.
I have disabled Wifi battery saving, nothing changes.
The bluetooth works, the WiFi direct works, but not the normal WiFi.
What can I do now?
Update:
Reflashing stock rom from sd card and crossing my fingers ...
Update 2:
And WiFi is back!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Now I have to root tablet once again.

Good - that would have been my guess: A bad flash.
But you don't have to root it and if you flashed .10 firmware you will find that Motochopper fails - doesn't work on .10 anymore.
Just unlock it, use the Minimal ADB Fastboot Tool to install TWRP 2.6.3.1 and then you can flash CROMi-X.

Nothing happens when I flash anything

I have tried, through Clockwork Recovery, to flash several ROMs and kernels.
I tried a Tiamat ROM. Looked promising. After flashing it and rebooting, the screen showed the proper custom boot animation and then it went into Honeycomb. Everything was the same as before. Looking in system information, it still says that I'm on stock 3.1 and using the stock kernel. I tried the Tiamat kernel and the Blue ROM, same thing, it just never changes anything except the boot animation.
Troubleshooting I've done:
Tried to flash it with older versions of CW recovery
Tried to flash it through ROM manager
Anybody know why it's doing this ****? It's rooted 3.1.
How did you root?
I used this
http://forum.xda-developers.com/showthread.php?t=1073884
I can confirm that the root is working perfectly fine.
Do you have access to your external SD card from honeycomb os?
The U.S. 3.1 doesn't work with MicroSD cards...does it?
EDIT: Nope, it doesn't work still. Just tested.
Do you have superuser? If not, you may want to reroot again. Something, may not have worked properly the first time.

Yep, I got superuser. ROM Manager even makes Superuser ask for root privileges before rebooting to flash, so I know that the root method I know isn't the issue.
I'm having the same problem.
I tried flashing the kernel, ROM, anything - it won't work. It just boots back to stock. But now I have a problem my wifi has an error.
Arrgh! The problem is RomManager's CWM. You actually CAN get it to flash things if you go into "mounts and storage" and mount /system and /data and all of that but DON'T. It will not work out well because it can not properly wipe system and you will wind up with a wifi kernel version mismatch (which will display as "wifi error" in settings). You need to flash the Tiamat CWM recovery from fastboot. I detailed the process for another person in this thread:

Relock US Xoom Tiamat 1.4.4 resulted in hanging at Motorola logo
By the way, you will have to do a full wipe of ALL of your internal storage (so make a backup on your computer) and flash the ROM from an SD card.

Thanks mikeserv, I'm so glad you are helping people who get snagged by that CWM recovery. It was a nightmare, and I've on a tear about it.

TF101 B70 - Problem

I'm some noob with Asus Transformer
I was using Revolver ROm, but I want to go back to stock rom, so with CWM I've used my nandroid backup of 8.5.9.19 rom, with root and cwm, which worked perfect, then with OTA Root I've tried to remove temporarily and that's ok, but when I've tried to updade via no way to do it, since que cwm it's not the stock one.
I've downloaded the 2 files from the 1st post and execute as indicated, it worked, now with .13, but I have to major issues:
1 - WIFI - not recognizing my router, find's all the ones around but not my own, never had issues with this, I have my Galaxy working perfect, I remember with Galaxy that there some change to be made in order to make it work when that happens
2 - Stock Recovery - if I want to do a wipe data, it works ok, but when I try to use it for Recovery,starts and hangs right after with the triangle displayed
I have a B70 device, so reading around looks that nvflash as some problems
My ideia is to have a net connection to download a newer version and correct the mess I've done
Thanks for your help
I have Razor Root and RecoveryInstaler in my microcard, but if I want to aply them returns an error
Sorry for the double post
edit. Problem with WIFI related to channel in my router, changed to 11 and works, update made and chennel 13 can be used again

Stock recovery is just that, it doesn't have options like a custom recovery (CWM).
Basically when you boot into stock recovery it scan for an update package, if not there it goes no further.
You indicate you have .13 firmware. Razorclaw need .19 firmware to work.

TouchScreen stopped working Tf300t

Hi i'm new to all of this but after reading a lot i decided to root my asus Tf300t and instaled a recovery ( CWM).
i instaled a custom rom ( cleanrom 3.4.2) and everything was working good ,but i decided to flash the Unters kernel for Tf 300T.
It reboots and a message appears Android is upgrading Panel Firmware 0%. After that Touch Screen never worked again .
I tried reinstalling cleanrom , stock rom downloaded from Asus Website WW_epad 10_4_2_20 was flashed with fastboot without
results. I do not know what to do next , any help is really appreciated.

This happened to me once. You must make sure that the CWM you installed is for JB, not ICS. Even then, CMW might give you problems. I tried to flash the stock rom you mentioned (10_4_2_20) from CWM recovery without success. I extracted the above ROM twice in my laptop. First try gave another zip file*. The second time would create a folder with a blob file inside. I transferred that blob to the platform-tools folder. Went to CMD (run as administrator) in Windows, then to the platform-tools folder, and issued the following commands:
fastboot -i 0x0B05 flash staging blob
took a few minutes to finish (rebooted a few times if my recollection serves me right. You might want to check other threads for accuracy). Once done, type:
fastboot -i 0x0B05 reboot
You're done. Custom recovery has been overwritten. If you want TWRP, you can install it again with ADB. Hope this helps.
* I've been flashing this zip file with TWRP recovery without encountering any glitches.
Thanks for your quick reply. Did what you told me but without success.
I forgot to say that the first time I loaded the stock rom 10_4_2_20, automatically lost the CWM recovery and as I have no dock can not even have
access to anything. Also I can not load the recovery again.
I talked to ASUS support and postage plus diagnosis is 50 € plus the cost of repair. And if I choose to send it to ASUS, the pad is locked again.
I do not know what to do anymore.
:crying:
What do you think I can do more?

If this thing doesn't boot and you've no access to custom recovery, I can't suggest anything more. Sorry. Does it show in windows as fastboot device? What does ADB say when you type the command?
I do not think you understood well, I can do the boot, the touchscreen does not work after having appeared "Android is updating Firmware Panel 0%."
As I do not have a dock, the pad stays at the initial settings menu when a new rom is flashed because touchscreen do not work.
My problem is only the touchscreen .
And now because i flashed stock rom i lost recovery and from now on i can not enable install from insecure locations in android .
For that reason the pad w'ont let me install another recovery again.

Evidently, I have a hard time making out what you're saying. For instance, this: "from now on i can not enable install from insecure locations in android.." What are insecure locations in Android? Beats me.
In short, you're right. The reason I gave directions was that I thought you were asking for a way to flash stock ROM (104220), which apparently you already had ("..because i flashed stock rom i lost recovery..."). If you already have the latest stock ROM on, then I totally misunderstood. Forget I ever said anything.
Thanks for trying to help me.What i mean with unknown sources is an option in Android settings - Security-allow programs install from unsecure locations
I think this is more clearly now.

That setting in android has nothing to do with flashing a recovery from fast boot. Can you get to fastboot? Yes? Then you can flash a recovery from a PC.
there a new update rolling just wait
it may fix your problem first go back to stock
Yes i can use fastboot but if i try to flash a .IMG recovery it gives me always error, but if i flash stock blob files it goês OK .That's why i thougt that was necessary to enable install apps from unsecure locations.
OK i went to stock but touch screen still not working.
try cold booting 2 times
Tryed cold boot 5 times.Didn't work.I think that the problem is with painel driver .I want to know if driver is loaded with ROM or not.
This is solved. I sent the tablet to ASUS and they despite being unlocked, solved the problem without any cost, because it was not a root cause
that this happened, and activated the Asus warranty. I must say they were very honest and professional.
Congratulations ASUS.:good:

[Q] wifi will not turn on; TWRP cant decrypt internal SD

I have two problems right now. First, I have an encrypted TF700t. I went through each step successfully to load this ROM:
[ROM]★★★[TF700 KitKat 4.4.4][CROMBi-kk][F2FS | DATA2SD | ROM2SD | CM11][July 19]★★★
I unlocked the bootloader, no problem. Relaoded and used stock Android. I then installed TWRP, again no problem. Again reloaded and used stock android, no issues. I could open TWRP, put in my decrypt password, and everything was going fine. I loaded up the above ROM, and got to the point where I was going to put in my Google info, and it hung at "turning on wifi." I skipped that step, and got into settings to turn it on that way, but no joy. No problem, I'll just re-flash the ROM and try again, and if that doesn't work, I'll try a different kernel. The problem is now, TWRP doesn't accept my password. So I have no access to my internal SD card. I loaded android back up and changed the encryption password, but that didnt word. I reflashed TWRP through ADB, but that didn't work either.
So, does anybody have any suggestions as to how I can either 1) get my wifi turned on, or 2) fix my encryption issue?
Thanks
Quick thought - does anybody know if I will cause any issues by flashing CWM over TWRP? I would like to try to reinstall the ROM through CWM and see if that works since I cant do it through TWRP right now.

5.0 to 5.0.1 Update Manual Flash (NOT OTA)

Ok so.. here's a quick guide to flashing 5.0.1 on the Nvidia Shield Tablet. I have the 16GB Wifi version so if you have a different version (LTE or non-US tablet) this guide may or may not apply to you. I also essentially dirty flashed this in CWM recovery. If you're using TWRP WIP, no idea if it will blow up or not. Standard disclaimer applies if your Tablet blows up or anything, i'm not responsible. You do these steps at your own risk. I'm going on the premise that you have the Shield drivers already installed and have some flashing knowledge.
This is an upgrade from 5.0 to 5.0.1
This guide DOES NOT utilize the OTA zip that your tablet downloaded.
1. Download http://ota.nvidia.com/ota/rom/productionBL-droid-signed-wx_na_wf-full_ota-29082_493.9700.zip (AGAIN, US 16gb WIFI only, there's another thread here somewhere with other full download links) I copied it to external SDCard rather than tablet storage.
2. adb reboot recovery to get into CWM or shut down and use the hardware keys to reboot to recovery
3. In CWM, install zip from external sd card and flash it like a normal rom. CWM reports this sucessful and reboot to 5.0.1 and let it settle. It updates binaries and blah blah. Oh also root and recovery are now gone. You should still have fastboot.
4. reboot into fastboot, hardware keys again or using adb reboot bootloader.
5. Now you follow the excellent post by sandrodjay for restoring CWM and root. (If you didn't wipe, most of the preliminaries in sandrodjay's post should already be done. Debug mode and whatnot) http://forum.xda-developers.com/shi...t-lollipop-t2972316/post57719881#post57719881
After the dust settled for me, i was on 5.0.1 and had CWM and root back. YMMV.

Did you for download full ota zip 700mb or did you try flashing partial which you would get through system update
Full ZIP not OTA. The 700mb download. Also i'm using the flashed recovery.img from sandrojay's post which is CWM 6.0.5.0. Are you guys on 5.0 or 4.4.4? I suppose i should mention this is an upgrade from 5.0 to 5.0.1

I've got good news... Your data and apps remain untouched, only litle problem depending on number of apps is time to "optimize apps" on first boot after update

Did it work?
Just to make it clear for all, I've flashed the wifi version....
Tried with all (really all) the recovery in XDA ending with error.
The only recovery that worked is the 6.0.5.0!!
Updated dirty flashed but ended with lag for me, so clean install, and now all is good.
(was unlocked bootloader)
Lost recovery and lost root of course, but with adb takes 2 minutes to put them back.

+1 as I've also just flashed the full wifi update to 5.0.1 using CWM v6.0.5.0, without wiping data, and everything came back up nicely. Still giving the tablet a chance to settle in after re-rooting with SuperSU v2.40, but hoping that the extreme lag doesn't return. If it does, I suppose I'll have to try a full wipe.
One thing I noticed is that after the very first reboot (without rooting, immediately after flashing the update), the system was very busy, and this could have been due to FolderMount trying to mount folders on boot using root when the tablet was NOT rooted. I'd recommend disabling FolderMount from auto-mounting on boot if you have it configured that way.
Thanks for providing this full 5.0.1 update package OP!
