Hey guys
I'm a happy owner of a new Iconia A500 bought from Amazon . It isn't brand-new but new-enough-for-me lol. It seems it was updated by OTA or something because it has Android ICS 4.0.3 on it.
Tech info:
Model: A500
Android version: 4.0.3
Kernel version: 2.6.39.4+
Image version: Acer_AV041_A500_RV05RC01_PA_CUS1
Compilation version: Acer_AV041_A500_1.033.00_PA_CUS1
Image part number: FM.S14A0.00Y
I read a lot and noticed there's a lot of info but it isn't very organized. I see there is CWM and TWRP, there are stock ROMs, ICS and JB and maybe a linux or two out there, but the instructions on using them aren't very clear.
I know I have to back up my SBK because it's something important. Thing is, how to?
Actually, in the case of a brand new Iconia which I want to get JB/any-other-custom-rom on it and have the possibility to go back to stock in case I screw up (or in other words, how to avoid a brick or how to recover from one if possible), what would I have to do?
In other words, what would be the steps I'll have to follow in order to play safe and backup my current state so I can start flashing custom ROMs like custom JB/ICS and kernels? what do I have to read and in what order? I already have experience in flashing & cooking ROMs, recoveries & bootloaders for HTC Magic, Motorola Defy and MT6577 devices, but this whole nvidia environment is new to me.
Thanks in advance!

DARKGuy,
I just recently took the plunge and experimented with various ROMs. The link below pretty much details all the required steps and links to files:
http://forum.xda-developers.com/showthread.php?t=1622425
Remember proceed at your own risk !!. Before doing anything, backup any items (docs, mp3, books, pics, etc) you want saved.
DOWNLOAD ALL FILES BEFORE STARTING !
Practice placing the A500 into Recovery Mode ( PWR + (-) Vol key) and APX Mode (PWR + Reset button (paper clip needed)). You need a micro SD card installed to perform the upgrade.
Download the latest USB drivers from ACER (1.00.0524) and install into PC. Verify they work in both USB drive mode and APX mode. Make sure tablet has USB Debugging enabled (Settings). Verify the drivers work. Boot tablet normal and connect to PC, you should see Acer Tablet with SD drive and External SD drive (if micro SD installed). Files\folders should be viewable. Turn table off, then restart into APX mode. You should see new hardware found, ADB driver. You shouldn't see any errors in device manager. If everything is working fine, you're ready to proceed.
Basic Steps:
1) Get CPU ID. I used File Explores ES app. Folder Local\Sys\Firmware\Fuse and the file is acer_cpu_id. Text file. Remember to add a zero in the beggining. ie mine started 33c20c.... My CPU ID is 033c20c....etc, Write it down.
2) Download the tool and generate your SBK with the CPU ID. Write it down. It's 4 sets of numbers, ie 0x520A1300 0x78498901 etc.
3) Root device. Here' the link: http://forum.xda-developers.com/showthread.php?t=1546593.
4) Install bootloader and recovery rom. I used Blackthund3r APX tool. Option 17, ShirlaxCZ V8 Bootloader and Thors 1.7.3 recovery tool.
Once this have been completed, successfully. You can download any JB\ICS you'd like to load. Just boot into recovery and load from SD card.
I would also download a stock image in case you want to go back.

Hey sorry for the late reply, I must say that was a very elaborate yet useful answer and I was able to backup my important data aswell as installing ROMs like crazy. You rock man! big thanks for the help and guidance!
root
get bootloader + thors recovery 1.7.3 cwm base(only cwm i found to work with aroma installer. which some of the newer roms is a must)
backup your files before u wipe.
flash away.
trying to find a rom that will let us a500 users use multiwindow manager, this would be superb!
will post back i find that golden ticket.
Hi
So i have been here (XDA) for a while and recently i get more and more annoyed (as you can see in my signature) when people post questions that create more questions
For Example :
[Q] After kdz update phone dont boots up
Hello,
before 30 minutes I flashed the kdz file for android 4.1.2 for my region.
My problem is that my phone didnt boot since then.. it stucks at the LG logo.
What can I do?

This was posted in general Q&A L3 L3II L5 L5II L7 L7II
Now How In The Hell To Answer Safely And Correctly ?????
Well that's where THIS post comes to place
I will explain how to ask question in order get the answer fastest possible
These Are Questions
You NEED To Answer In YOUR Post
(more of them you answer the bigger chance you get for quick resolution)
1. What exact phone model is it ? (check the sticker under the battery and include it in your post)
2. Did you use any guide ? (best if you paste the link and include it in your post )
3. What exactly where you doing (post what were trying to do, name of apps/programs you were you using etc.)
3.a If you have app problem make sure to include name of the app and source of download
3.b If You have flash problem make sure to include FULL name of the ROM and flash file also include source of download, program used to flash/update(if you are using CWM / TWRP / OR / or any custom recovery make sure to post VERSION number), your operating system, Usb ports info (1.x, 2.0, 3.0, 3.1), was / is your battery full,
4. Can you provide LOGCAT ? GUIDE HERE If Needed (adb for windows in attachment)
5.Can you provide SCREENSHOTS ?
to provide screenshots without any app, root or trouble use adb (if you on linux no need to explain, if you on windows see link at the bottom) paste this code to terminal/cmd and press enter every time you want to make screenshot
For linux/ubuntu/etc.
Code:
adb shell screencap -p | sed 's/\r$//' > screen.png
For OsX
Code:
adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > screen.png
For Windows (*no 1 liners don't work)
Code:
adb shell screencap -p /sdcard/screen.png
adb pull /sdcard/screen.png
adb shell rm /sdcard/screen.png
This will make screenshot named screen.png and save it (linux and osx home folder) (windows adb folder or root of system drive (i.e. c:\) depending on configuration) {rename "screen.png" to your desired name and remember this will overwrite the previous screen if name stays the same}
5. Post answers in YOUR POST and wait for me or someone else to happily answer (not bombard you with questions before we can help you)
SIMPLE SOFT-BRICK GUIDE
adb_fastboot_and_other_tools.zip* 1.extract it to any folder 2.open the folder 3.press shift key on keyboard and right click the mouse and select "open command window"
your cmd will open here and you will be able to use adb and more if needed

can you see any devices in device manager ?
like:
adb ?
ports ?
usb composite device ?
does phone display anything ?
does it boot ?
can you get into "download mode" ? (pull battery out, plug usb to pc, press and hold vol- button, plug usb to mobile, wait few seconds, put battery back) it should display Download Mode on black screen then try kdz

Kernels for LG E400
Hi,
I'm a new user of XDA, but I've already tested part of ROMs for my phone (model in title).
I have a little question about kernels: some ROMs have a kernel in other ZIP file. But after correct installation (by CWM Recovery) I have blurred screen. Now I'm using JellyBeanRevenge (or some like that ) and it's work fine, because Author gave good instructions; but in some of other kernels don't works. Why?

Are you sure the kernel was for your baseband ? ie v10x; v20x ?
when changing roms v10 to v20 and back certain files get rewritten and not in same format anymore so errors occur
also not all kernels are stable and everyday use
so.. read about the source and features / defects of kernel you want to install and ensure you check if your base stock rom is v10 or v20
1) So I'm completely new, is there an introduction guide to rooting and installing custom ROMs? Just so I can know what I'm doing.
2) I'm running linux right now, do most popular methods support it or should I do everything on windows "just in case"?
3) Are there any recommended ROMs or mods for low specs phones like the L3? I currently have a L3 E431g I'd like to mod
Your phone is l3 ii !!!

DON'T INSTALL ANYTHING FOR LG L3 IT WILL BREAK YOUR PHONE !!!
most tools made for windows and that's what i would use (virtual machine will work)
first use program and youtube guide in my signature (show content) to root your phone using vroot (its easy and works on any software version )
then have look here http://forum.xda-developers.com/showthread.php?t=2654327
if your phone has 1 sim-card
you can unlock bootolader and install custom recovery using things in first post
ROM's Are UNDER DEVELOPMENT dont ask how long (about ~2 weeks)
there is mod made by @slipsystem but still in beta stage so no official release (subscribe to E430 thread for update in post #2 )
Thanks for the anwser IGGYVIP. I'm guessing that the E430 and E431 are similar enough that almost everything will work on both phones, right?
I already rooted mine, and I guess I'll wait and see how slipsystem's mod works when is released.
Nice one

Actually I lied . I though that I had rooted it but I actually never ran the program. I'm trying now but I can't seem to make it work (the vroot method). VROOT connects to the device, installs some chinese manager app, reboots and then nothing happens. VROOT eventually shows that it couldn't root the device and asks if I wanna retry, but it never manages to root it.
Does the superoneclick works on the 430?
I will update #1

Hi there raducux,
Well, this was about another situation, but mixing with ROM's cooking I was able to brick it again it was mrsim who help me (mod at china-devices.com, credit where is due). But I will tell you how I did it.
You need to have the adb android drivers installed and flashtool v5.1 or up (the one I used, but some people use the 3.1 version).
Download this ROM from needrom (scatter file compatible with FT).
Link: http://www.needrom.com/wp-content/uploads/2014/11/Y800_UMI_20141104_1907xx-s7yler.zip or
http://www.needrom.com/download/umi-zero/
Extract, and in flashtools select the scatter file inside the directory you extracted. Press flash, and (after pressing flash) connect the phone to the USB port holding the volume down key (so the phone connects in META mode), and the process should begin.
If all works well after flashing the phone should boot the new ROM, its version 3.01 so you have to upgrade it.
If that does not work, tell me a few things... I suppose the phone does not start or appear the 'Zero' logo, but tell me if when you connect it to the computer you ear the normal plugin USB sound?
FlashTools (all versions)
http://helpadude.com/sp-flash-tools/
Universal ADB Driver
http://www.needrom.com/download/universal-adb-driver/
Tell me if it worked, or if you need more help tell me what happened and how the phone responds. lot of people here also that can help. My 1st thing I check when buying a new phone (for many years now), is if it's 'XDA' Supported...
cheers

indeed. i too have been messing on xda a lot for a long time.
i managed to get into twrp again.
so that must be good...after. the battery died..;.butr mtk preloader doesnt instal;l
please tell me..first i need to hit download only...and after that.... ? the steps are a bit missleding .
---------- Post added at 03:10 PM ---------- Previous post was at 02:58 PM ----------
i managed to bioot the device in emui !!!! this morning..i could acces twrp. pressing volume down when connected to pc ..and the chinesse recovery pressing volume up ... rootjoy cant flash the device as it sais it is unsupported, now...i reeallly need to know the steps for going back to stock
---------- Post added at 03:29 PM ---------- Previous post was at 03:10 PM ----------
i am running antarct s emui . with twrp recovery... i need dto know the sp flash tools steps correctly to flash back to stock
preloader doesnt install correctly in pc because volume down...takes me to twrp...and volume up...to the chinesse recovery of huawei,
so preloader starts installing, but when in recovery..it gets dissconected
Could you tell how did you put it in meta mode? I have a Zero with no preloader and in windows it shows up as unknown device. No matter how I try to boot it up (vol- vol+). Other than showing in windows, it's dead. Is there a way to revive ti?
Flashing Stock ROM failed.
Now won't boot of course, nor I can access fastboot. It's gone.
After turning Tablet on shows: "Boot Failed. EFI Hard drive"
and straight after that: "Boot Succeeded - Enter Setup"
Then BIOS like or actually BIOS shows - Title - VALLEYVIEW CO PLATFORM...
How can I fix fastboot? Or Droid Boot? I didn't even know I had BIOS in background?
I guess all blame me because I had Rooted... Is it trashing Tablet next step? Cause I couldn't find anything. I just wanted to go back to Stock ROM.
Anyone saw somewhere how to bring back fastboot? Or make it boot-able anything useful?
In that BIOS there is Boot Manager option and offers
- EFI Hard drive - Device path : PciRoot (0x0) /Pci (0x17, 0x0) /Ctrl (0x0)
- EFI Internal Shell - Device path : MemoryPapped (0xB,0xFFF50000,0xFFF8FFFF) /FvFile(C...
Can I somehow go somewhere from here?
Device Manager
Boot Maintenance Manage - has option Boot From FIle
- Boot Next Value... I'm lost.
I'm browsing that bios all possible ways to find something useful, but with no success.. Please help.
EDIT1: I find out that holding Power button and BOTH volume keys will start FastBoot - But mine stucks on "FastBoot Starting..."
There is already thread on xda discussing what to do when you got UEFI screen. restore-kitkat-bios-830-1050-v2 tool is the answer.
I lost that thread, so I'll answer to mine thread:
My state was - tablet ended up in UEFI. Couldn't get through but I did on the end with novice mistakes. So, here is advice and mistakes which cost me some time.
Spot that you need to be in DnX mode - kk-tool says that - pressed Volume keys and power button. Then tablet says FastBoot Starting...
Do not run KK bios restore tool with Intel Phone Flash Tool opened. Close Intel Phone Flash Tool. Then run kk-tool and follow instructions.
Then use Intel Platform Flash Tool to flash ROM (you need android driver and USB driver). I have used and working (not first image but some other second download worked): YT2-1050F_S0198_150422_ROW. Then I have tried to update to Android Lollipop but install failure.. Killed KitKat.. I'll google more tomorrow.
Let me know if you find working ROM able to update all the way successfully to Lollipop.
Looks scary when you see grey-blue UEFI screen - Oh, I must screwed up pretty bad if I lost FastBoot... You might think something like that, like I did. But kk tool really kick-off and helped.
I have searched quite thoroughly in this forum but I can not seem to find the restore-kitkat-bios-830-1050-v2 tool . I have this same problem and can not get my 830LC running.

Revive Dead/Hard Bricked/Dead after Flash/LED doesn't light up the phone - K8 Note (XT1902-3)
If you tried to downgrade from Oreo to Nougat and your device is hard-bricked. Don't worry, follow the procedure below...
1. If your device is fully hard bricked and doesn't boot up by pressing the power button, and also the white LED light doesn't light up while u connect the charger/power on the USB to the PC. Try pressing all the 3 buttons, Volume Up+Volume Down+Power Button for about 25-30 seconds and connect your phone through USB to SP Flash Tool (install all drivers before as said in step 3) and see whether it detects your phone (If it detects, go to step 3). If this also didn't work, don't get panic - follow step 2 (Dismantling your device - the only way to recover. But be cautious while doing it, use proper tools).
2. Remove your phone back cover carefully and disconnect the battery connector as shown in the video
. Use proper tools and a screwdriver. Connect the charger and see now, the LED light will blink surely (If it doesn't blink now also, then it's a hardware problem, you should go to the service centre only).
3. If the LED light blinks properly, then go to SP Flash Tool (download the latest version here - https://androidmtk.com/smart-phone-flash-tool), and in Options->Option go to Download and check USB Checksum and Storage Checksum. Then choose the option Download Only in the drop-down list. (Dont Forget to install all Drivers before - MTK Drivers and Lenovo USB Driver, links below)
MTK (USB DA COM,Preloader USB VCOM,USB Port,USB VCOM) Drivers : https://spflashtool.com/download/Driver_Auto_Installer_v1.1236.00.zip
Lenovo USB Driver : https://lenovousbdriver.com/download/lenovo-driver-v1-1-33
(CAUTION : Don't select Format all+Download because if you mistakenly chose Format All+Download option it will delete all your IMEI no, Device Serial no, WIFI MAC address, and Bluetooth Address. But don't worry you can retrieve it through this method : https://forum.hovatek.com/thread-12328.html or
. Make sure you know all your IMEI no, and device serial no {You can get that from your device box, there will be a label in it}.
4. In the Scatter-Loading file click Choose and load MT6797_Android_scatter.txt under the extracted Oreo Rom (whichever version you prefer)

Downgrade to Nougat from Oreo - K8 Note
1. First Unlock your bootloader through the following steps:
(Before this take a backup of all your files, apps, and data because it will factory reset your mobile)
{Unroot your phone if you're rooted, also Uninstall any modules or Xposed or rooted apps if installed}
i) Go to Settings->About Phone and Tap on Build number for about 7 times, this will enable the Developer Options. Now go to Settings->Developer Options, switch ON it, and enable OEM unlocking & USB debugging.
ii) Next, Go to Fastboot mode manually. Switch off your phone. Press Volume UP+Power Button at the same time. While the phone vibrates release the power key and hold the Volume up button. You will see three options. Select fastboot option using the Volume UP key (for scrolling) and select it using Volume Down Key (for selecting).
iii) Extract minimal_adb_fastboot zip file on your PC -> https://androidfilehost.com/?fid=457095661767103465, and press Shift+Right Click inside the extracted folder and give open the command window here. Then Connect the mobile to your PC using a USB.
iv) Then type : fastboot oem unlock {Note: This will wipe all your phone data & make it as new, so take a backup of all before doing it} (Then press the Volume Up key in your mobile after it prompts)
vi) Type : fastboot reboot (It will boot up your phone normally)
vii) That's it now you have unlocked your bootloader successfully

7. Then select Restart System now in Recovery Mode (Volume Up and Volume Down to Select between options and Power Button to OK). Viola...!!! Your system will reboot and your'e on Nougat Rom...!!!
{Note : After downgraded to Nougat, you won't get OTA update to Oreo. But you can get all the OTA updates of Nougat. Main thing: Don't use "fastboot oem lock" in downgraded Nougat Rom it may brick your device. Because while you lock the oem in downgraded version, the system updates will look for Oreo Rom so it wont boot as you already downgraded. If it's bricked try flashing Oreo Stock Rom using spflash tool. So try keep the "device unlocked. Orange Status......" text that comes while you boot up, always in downgraded Nougat Rom}
Follow the procedure correctly so you can retrieve your K8 Note, don't blame me if you totally damaged/bricked your device.
Hit Like and Press Thanks...!!!!

If u have installed twrp in oreo get rid of that and go for stock oreo recovery, if u have rooted already on oreo means unroot your mob, uninstall xposed/magisk manager if it's there. Then start the process with unlocked bootloader, go to fastboot mode and run flashall.bat inside the Stock Nougat Rom zip. After the process finished successfully the device will boot automatically. You may get some errors or not, no probs about it, go to recovery mode manually and factory reset your mobile. Restart the mob. This will surely work. Go for it...
Anyways, I feel good that you retrieved your phone back through Oreo Rom. :good:
