For those of you who want to install custom ROM using TWRP recovery, here’s a fail-proof method that will make your new custom ROM boot every time (in my experience).The only difference between the usual method and this one is that we will also be formatting /system partition, which if not formatted sometimes causes bootloops when installing new custom ROM.This method will work on any rooted Android smartphone or tablet with TWRP recovery installed. And also will work on all types of custom ROMs including CyanogenMod (CM11, CM12), TouchWiz, Sense, etcetcBefore we begin, make sure you have TWRP recovery installed (if you don’t, see our )Step 1. First download the ROM zip files you need.
Usually there’s one or two zip files. You can download these files straight onto your phone or download them to your computer first then copy them over to your phone. (Also you can use an and USB flash drive so it won’t take up space on your phone/tablet.)For AOSP ROMs like CyanogenMod CM11 or CM12, you will need an additional Gapps zip file.Once files are downloaded, make sure they are not corrupt.
You can do this by opening the ROM zip files with. If you can see the contents of the zip file fine, you are good to go. Otherwise, your files are bad so re-downloaded them! Once in TWRP recovery, choose “Wipe”.Note – You can also “dirty flash” without wiping. This is recommended for installing stock ROMs if you are installing stock ROM on top of another stock ROM. If that’s the case, skip this step.Choose “Advanced Wipe”.Select Dalvik Cache, System, Data and Cache then swipe to wipe. By wiping the system partition here, we will make sure our file structure is perfectly clean before installing a new ROM.Step 4.
Choose “Install” from main menu.Choose “Storage”.Choose the storage you have your ROM zip files in. Here you can choose internal storage, micro SDcard, or USB storage (if using OTG USB Flash).Browse your file system and find the ROM zip file. In this example, I am installing CM12 ROM so I will be choosing the ROM zip file below beginning with “cm-12”.Swipe to install ROM.If you are installing an AOSP ROM like CM12 like I am doing here, repeat this step and also install the Gapps zip file.
Otherwise go to next step.Step 5. Reboot and you should see your new ROM boot up.Step 6. If you get to the Welcome screen or your phone boots, congratulations! You have successfully installed a new custom ROM onto your Android smartphone/tablet!
Hey Jose, i experienced the same problem a few months back. Finding the stock rom of your device might help your case.
Just follow these steps:Boot into twrp, wipe, advanced wipe,Check:-Dalvik Cache-System-Data-CacheThen go to install, then flash the stock rom.it should boot up if you flash the right rom. Also make sure the file is not corrupted.Also, some devices are picky and will only mount specific roms compatible with their build number, you can do more research about your device at google.(I dont know if this is right, but one thing I do is extract the rom to my computer, if it gets extracted all the way, then you can bet that its not corrupted.)I guess thats all, and having a recent backup of your system is REALLY helpful, as it will be easier to restore the rom without going through the trouble of finding it on the internet.Hope that helps, anything else, email mePeace ^0^.
The ASUS Transformer Infinity Pad TF700T is a great tablet. Well, at least until ASUS released the Android 4.2.1 update.
That basically turned a great tablet into a piece of garbage. Well, not really garbage, but close enough. The biggest problem, at least for me, with the Infinity tablet ended up being lag. I basically abandoned the tablet because I couldn’t stand to use it. Performance was atrocious, and despite the Infinity’s superior specs, I actually preferred my Nexus 7 for most tasks. Taking matters into my own handsFor my first few months, I actually believed that would satisfactorily resolve my issue.
Unfortunately, factory reset didn’t work too well. Sure, I’d get by for a short time, usually 1-2 weeks, but I’d be back struggling with lag shortly thereafter.
I got frustrated. So, I decided to set about to correcting the issue — since ASUS doesn’t care — and reclaiming my tablet. I decided that I’d unlock my tablet and install a custom rom. In particular, I opted for the Crombi-KK ROM.Getting startedThe first thing you need to remember is that you’re voiding your warranty by even starting this process. That’s because your first step involves unlocking your tablet’s bootloader.
I was okay with this solution for two reasons. First, my tablet is 2 years old, so repairs aren’t covered by the warranty. And second, I know ASUS isn’t going to fix the issue. Please read this entire post before trudging off on the installation.Once you’re okay with voiding your warranty, the first step is to unlock your bootloader. ASUS provides a bootloader unlock tool that you can download directly to your tablet.Follow this link and select Android from the drop-down menu.
Then expand Utilities, scroll down to find Version V8For Andorid 4.2. I selected the. It’s packaged as a.rar file, so use any of the (I used ) to get the file into an Android OS.apk file. You’ll install the new app onto your tablet. Note, you should have the box next to Uknown sources checked (look under Menu Security) to allow installation. Open and run the sunlock tool once it’s installed. This should take a minute or two, so be patient.
You’ll know it’s done, so just wait. Installing TWRPWith the tablet unlocked, you’re ready to install the custom ROM. I followed, though they’re a little confusing at times. Note that you don’t need to root your tablet to finish this project.If you haven’t installed a custom rom, do a quick search for custom rom installation, just to get a feel for what’s going on.From this point forward, you’ll use your desktop computer for the installation.The first step in the process is to download (in this case TWRP — Team Win Recovery Package) and — do this while you’re unlocking the tablet, it’ll save you some time. Doing some TWRPingFor me, the most difficult part of this custom ROM installation was the TWRP step.
Don’t get frustrated, because here’s what you need to know.Use this (Windows) program to quickly get ADB on your desktop. ADB is part of the Android software development package, but you only need this small portion. Save yourself some time, hassle, and frustration with ADB Setup.
Be sure to install the file directly to your C: drive. If you’ve done this right, you should have a folder structure that looks like this:This will enable easy access in the very near future.Download (if you haven’t already) the TWRP file. It’s packaged as a.zip folder, so use Windows (or your desktop’s).zip unpacking program to extract the files to your desktop.
Open the folder and look for the boot.blob file.Rename this to twrp.blob (right click rename twrp). Note that you can leave this as boot.blob, just remember the name for later.Copy this file over to your ADB folder, which should now look like this:Now, you’re ready to run some fastboot magic and install the TWRP recovery. This is extremely easy, though the instructions don’t tell you how (they assume you already know how to get fastboot). FastbootingPlug in your tablet via USB and make sure your computer recognizes and installs the device drivers. If your computer doesn’t, this is a pain and you’ll need to go back to the.If you’re fortunate, Windows (or your system) will recognize your ASUS tablet, install the proper drivers, and you can reboot into fastboot mode to use ADB to flash your TWRP recovery program.Get started by opening the terminal on your desktop. In Windows, use the Windows Key + R to open the run dialog. Type cmd in the box and click Enter.
You should see the command terminal (old DOS for you pre-Windows folks with a memory).Change directories to your ADB folder — this is why it’s nice to sit ADB in the C: drive.Now, shut down and restart your tablet while holding Power + Vol- (volume down). You should see a “funky” screen with 3 icons: RCK, an Android, and “WIPE DATA.” If you’re restarting, you didn’t hold down the proper buttons, so try again. This is the fastboot screen.Type the following fastboot commands on the line (no pictures because I already performed the step):fastboot -i 0x0B05 flash recovery twrp.blobWait about 10-15 seconds for the recovery to finish. The command prompt says something like “successful”.Reboot your tablet. Installing the custom ROMWith the tablet rebooted, it’s time to move your downloaded custom ROM file over. You can do this ahead of time and save the hassle of rebooting.
It’s up to you.I like to use Windows Explorer to move the file. Simply copy (or cut) and paste the cm-11.0-20140719-crombi-kk-tf700tsigned.zip file from your desktop to your tablet’s root drive (at least somewhere you’ll easily find it). Wait a few minutes for the transfer, then reboot your tablet back into fastboot (Power + Vol-).With fastboot loaded back, select the RCK icon — it should be flashing — and press Vol+ to select the option.You should load directly to the TWRP recovery module and see a series of 8 icons, beginning with “Install”.I prefer to wipe my devices before installing a custom ROM, so click Wipe Advanced Wipe and select the partitions (generally the first four for me). Wait for the wipe to complete and return to the home screen.Click Install and navigate to the location of the folder where you saved your Crombi file. Advanced tip: If you see a “signed” in the zip file name ( bestromeversigned.zip), make sure you check “verify zip signature” under the Install menu. Some devs sign their ROM zips – a better way to ensure file integrity than md5 sum.You’re ready to install the custom ROM by answering the questions and following the steps. Crombi includes the Google apps files, so you don’t have to worry about installing those from a separate file.
Complete the installation, restart your tablet, and you have a whole new device. A whole new worldCrombi is really helping me to establish a whole new relationship with my ASUS Transformer tablet.
You won’t see vast improvement for about 15-30 minutes as the device “settles down.” Be patient.One of my biggest issues was the lag of the tablet. That’s almost disappeared from the system.Admittedly, the ROM isn’t perfect, for instance, there are some quirks when I connect my keyboard, but overall, I’m loving the fact that I’ve reclaimed my tablet, and it’s usable.If you’re struggling to love your ASUS Transformer Infinity Pad, perhaps Crombi-kk can help you love again. Thanks for an excellent post. I encountered an issue with twrp – it could not see my rom zip file from the install button.
Solution was updating to the latest release (2.8) instead of the 2.6 I had installed. This also resolved an issue with my windows drivers I wasn’t even aware of yet. Moral: always check to be sure you have the latest release.
Here’s the link:.Also note the following from the TeamWin website that saved my bacon when trying to move my ROM file over:“Note: Due to a weird bug with our MTP setup, you cannot copy a zip file to the root of storage with Windows. You can change the.zip to something else like.txt and then copy it to the root and rename the file back to.zip once it’s copied to the device. You can also copy the zip into any subfolder.”Thanks again. Jeff, a couple other things – The fastboot command should have the letter “i” not the number “1” as in the following:fastboot -i 0x0B05 flash recovery twrp.blogAlso, the XDA post at has another wonderful tutorial on this same topic with a couple of additional helpful tips and links. He also reminds the reader to create a backup/restore image in case things go south, which is good advice.Thanks again for a great article.
I’ve been looking for a solution to the terrible lag problem that plagued this otherwise fine tablet. One of the advantages of the Android/open source option is the abilitiy to take matters into your own hands when your manufacturer (that’s YOU, Asus!) lets you down. Hiya Jeff!Thanks for your posting above! This is awesome!
Now my Asus Infinity TF700t is with its soul renewed! 🙂I had the serious lagging for ages until just recently I have decided to give it a factory reset. It begins with just Google-ing for ways to download or backup all Asus’s default apps like SuperNote, MyCould, MyNet, etc, even the Asus Task Manager and your website spotted my attention.You have made process/procedures or as you called it, ‘project’, so details and simple at the same time. Thank you again!
