Hi,
My I9100 behaves quite strange.
I am unable to perform factory reset (using code from keypad or command from settings menu) - the phone reboots, goes into recovery mode where I can select wipe data/cache. Doing so has no effect on my phone, after another reboot the I9100 restarts in the same state as before factory reset.
The other thing is that I am unable to format interal memory. After using command from settings menu it says that memory is disconnected, formated, and after that all data (pics, mp3s, etc) are still available.
Also I am unable to flash ROM with any stock (tried KE4 and KE7) or aftermarket (Lightening) software. I tried Odin with and without PIT/Re-partition, also with no effect. The phone boots into previous state nevertheless confirmation in Odin that flashing completed successfully.
And the most aggravating thing is that after I reboot phone I am loosing all the recent data. The phone is booting in the state from before couple of days, with no recent messages etc. Thanks to Google account sync, the mail, calendar and so on re-sync properly, but it is no good solution since pictures, todos etc are gone after reboot.
I believe the thing started to occur after unsuccessful update to Twitter. Tried to do Market cache wipe (as suggested for similar cases to I9000 users), but also to no effect.
Have you any suggestion what else can I do?

Hold down menu button + Volume UP + Power button
at splash screen release menu volume then power button .
In the recovery screen find wipe data factory reset and apply .

Everytime its stuck in boot loop and either the initial boot logo flashes or it stays stuck at the boot logo. Can please someone help. I read all the comments and lot of people having problem being able to get into Download mode but not in Recovery Mode. I would appreciate if someone can post a detailed response as to how to get rid of this issue.

Wipe data and cache from recovery then flash a rom, you will lose everything not backed up
There is a guide about howto fix this, search first next time
Sent from my GT-I9100 using XDA Premium App
im sure there is another thread around he with 2 people in it that had the same problem as you, flashing via odin or cwm and then still ending up with the same firmware as pre flash.
i'll see if i can spot it and post it here, i dont know if they got it sorted or not tho.

Mr. veyka perhaps i didn;t drive my point home. Recovery mode is inaccessible. I cant wipe unless i get into recovery. its simple logic. i need to be able to access recovery before i can wipe
@ OP

That is the thread that i had read which had the same problem as you, i havent read it all but the last few pages tend to lean towards that flash lock go ticked when flashing a ROM via odin.

Hey bud,
If you can get in to download mode then it should be ok, id try 2 things.
Go over to the the original android dev section and grab the CF kernel that was for the firmware installed, boot in to download and flash it via pda in odin, then try recovery again.
If that doesnt work, then download a full firmware from samfirmware and flash the main 3 files (Modem/CSC/Phone) and that should set your phone back to retail fresh.
ofc another reason could be your volume up button is broken

Oh, sorry, missed that, my bad
As said, flash cf root and see if that helps, if not check that your volume up key works within the os, if not flash to stock, and reset flash counter with a jig and send in for repairs.
If it does, cf root comes with an app called cwm manager that will allow you to reboot into recovery that way.

my volume up button works> the reason being you need to press volume up to get into download mode after the Vol down + home + power combo.
There are other people who have had this issue of recovery not available.

the chinese rom and checksum error are supposed to happen.
the chines rom is an old unstable version but is provided so we can root it to install cwm and flash a working rom.
after the checksum error you needed to power off and then using the buttons enter recovery mode and go to 'Fix checksum error' in advanced menu - after that reboot.
you should do the following:
a)go back and read the entire post on what to do because you missed the last part
or
b)try the backdoor method
---------- Post added at 12:21 PM ---------- Previous post was at 11:49 AM ----------
just read your entire post again...there's alot going on there isnt there?
have you tried flashing the update.zip again with 3.0.1 on it...get back to the chinese rom, from there install iconia root and root it. Then install cwm and you should be all good - if that doesnt work then use timmyDeans backdoor method it does it for you, all you need to do is install acer recovery installer to install cwm, backup the original stock recovery when the app asks you, you will need it to OTA Update successfully...
Doesn't flashing stock rom remove cwm?

V3 which I pointed you to is STOCK 3.2.1 with root. Once you get there you will be stable. If you want CWM then you will have to install it. It is NOT in the flash because the flash is stock ONLY with root. But since you have root, you can install CWM.
The serial number does NOT need to be saved in any file. Just follow the instructions.

Ok, now just download the stock image for your country and put it on your external sdcard. Use the power and volume + key which will launch stock recovery (which you now have flashed) and it will flash your tablet with the one located on your sdcard. This will have you back stock.

You have a "volume" switch on top of your tab (long silver switch on left side)
You control volume from this. Vol+ make sound go up (the right side of it)
Press it on the left side, and volume goes quiet (vol-)
So, as he said, with the tablet OFF, hold the VOL+ side of the button, then select PWR (power)
You have 2 recovery modes.
1. CWM Recovery (vol- & Pwr) (after you have root and cwm installed)
2. Stock Acer recovery (vol+ & Pwr)
Step number 2 with the stock acer recovery, should install the stock rom you copied to your sd like TimmyDean said earlier.

Please rewrite what you are trying to do. I have no idea what you are talking about?
Are you asking about stock recovery and flashing form a SD Card? If so, copy update.zip to your SD card and then run recovery. If you have CWM, then use it to select the update from the SD Card.
It's not clearly as to exactly what you have loaded and what you are trying to do?
LASTLY: You cannot take a backup from CWM and have the stock recovery install it. Stock recovery will only install update.zip which must be signed by ACER.

Since I'm quite familiar with linux, I tried this solution: http://forum.xda-developers.com/showthread.php?t=1971266

In Windows 8 it did show two HUAWEI Technologies device (no drivers though) in pink screen mode.
I can't access recovery mode either, holding power + vol up only does normal boot for some strange reason. Anyone can help me out here?

try put official GB dload file on sd card, then put sd card in phone press power up+power down+power...
maybe it'll help you.
I tried that too, and it still bootloops. Not much luck.
Go to recovery and wipe everything. Then, reboot recovery, and then try partitioning again.
I can't get into recovery by pressing power + vol up. It just does normal boot (which bootloops).
If there would be any other way to get into recovery (such as via ADB or update.app) would be highly appreciated.

Yes, you can boot into recovery via adb:
Code:
adb reboot recovery
But, you cannot use that until your phone is booted up.
If that doesn't work, you can follow these instructions to hard reset your phone:
http://www.hard-reset.com/huawei-u8800-ideos-x5-hard-reset.html
Good Luck.
I can't get it to do the hard reset either. It just boots normally, aside from the bootloop.
I believe I need to fix the partition first before I try to reinstall stock. I hear that stock doesn't work with custom partitions. Which is why I'd prefer to at least get some access to the device via USB in order to fix it.
Ah well. It's a failing device anyway. Even before the brick the camera doesn't work anymore, regardless of which ROM I choose. Maybe it's time to move on for me.

Hey, this is my first post well here it goes
Step 1 :- Format the sd card and put dload folder in it ( you'll get it from the official rom zip file)
Step 2 :- press and hold vol+ & vol- and then power button, it'll start upgrading
Step 3 :- now here is the tricky part!!! i was stuck here too and gone half mad well, let it reboot it will format cache etc and then bootloops, now turn off the device and then turn on pressing vol+ and power button, or u can try by pressing home, vol+ and power button, u'll b in recovery mode i.e in official rom builtin i guess.
Step 4 :- once in recovery, select reset factory default and clear partition cache, and then reboot!!!! Voila u will b able to finally boot successfully...
Now listen very carefully, u got only one chance here, cause if u reboot ur device again then bootloops will start again so in the first go, root the device by superoneclick and then install recovery i guess u knw all that and then u will be able to return to stock rom by flashing... once u've installed CWM then u r good to go bootloop wont effect ya SORRY FOR MY BAD ENGLISH THOUGH
I have installed 4.2.2 on nexus 7. As I had skipped account login at welcome screen, i could not login the account. I altered the apk of login. After factory reset my device has hanged on setup on welcome screen. I tried installing custom rom through stock bootloader but the bootloader says installation failed. How do I solve thia problem guys???
subin.nexus7 said:
don't know the exact steps, but i got it out of the APX mode and into the bootloader.
1. Tablet plugged into computer.
2. Held Volume Down + Volume Up + Power (simultatenously) for three seconds
3. And then released all, and pressed Power again.
4. Tablet booted into bootloader.
I thought that unlocking the bootloader ALWAYS voided the warranty, but in anycase I flashed reflashed ALL stock and locked the bootloader. Will be sending it to ASUS now. Thanks again!
EDIT:
So I wanted to verify that it was a CPU problem, and I downloaded StabilityTest again and ran the CPU load test. It crashed within two minutes, and went into AXP mode again. To get it out of AXP mode, the correct instructions:
1. Plug in the usb into computer
2. Hold Volume Down + Volume Up + Power simultaneously for like 15 seconds
3. The bootloader should show up.
4. If it doesn't, unplug the usb cable, and plug it back in and then repeat the these procedures.

Very helpful! I don't have a problem but I've read about others stuck in APX mode. This should be pinned if it works for those stuck in APX. Maybe you should change the thread title to something about APX solution so it draws some attention.

Well... being stuck in APX doesn't necessarily mean your hardbricked. (Corrupt or erased bootloader).
But being hardbricked DOES mean your device will default to APX mode.
To use a mathematical metaphor, one is a SUBSET of the other.

I'm sort of confused about the relationship between your edited post and what (apparently ?) kieso quoted, but I'll throw out a few suggestions:
1) AFAIK, there is no way to flash a dev ROM using fastboot (only the boot image of a dev ROM can be flashed this way). You said "bootloader", not "custom recovery" ... so that implies using fastboot. If that is not the case, then your use of terminology is not correct. (It's a computer - reporting details correctly is incredibly important).
2) If you bypass the WiFi login, an account can be added at any time later using the settings menu or simply by launching the Google Play (market) app - there is no need to "alter the apk of login", whatever that means.
3) I would recommend at this point that you start completely over by flashing a factory ROM using fastboot - see the sticky thread about returning to stock using fastboot. If you already have the 4.18 bootloader installed, I recommend you avoid like the plague any operation involving flashing the bootloader.
4) It should be obvious from the trouble that you got yourself into that you should learn what nandroid backups are and that you START USING THEM. The first thing you do after rooting is "make a backup", not "flash a ROM"
good luck
Thanq so much.But still some clarification needed

I guess I am having trouble understanding the sum total of information you have provided - I guess you have omitted some information or mis-stated something. No custom recovery sort of implies a full stock device, but yet you previously mentioned modifying/changing an .apk in /system... normally that would be possible only with a rooted ROM or a custom recovery to do that.
If your tablet is 100% stock, a factory reset of the tablet should allow you to boot once again - at the cost of deleting everything you put on the device, including all files you put on the (pseudo-) SD card.
If that is the case:
- press and hold power+vol-down until the bootloader screen shows up
- use vol-up/vol-down to select "start recovery" and press the power button
- an android lying on it's back should show up; this is the stock recovery splash screen, so
- press power+vol-up simultaneously for about one second - the stock recovery menu should show up
- select factory reset (with vol-up/vol-down) and press the power button.
good luck

when you say at the cost of deleting everything, does this include deleting everything in the bootloader because thats what I did when I used the command "fastboot erase bootloader"
Dear XDA friends,
i always hoped not to be one of those guys, who f****d up their phones to the point of no return. I really screwed up this time. Well, here I'am writing you about my screw up.
I unlocked, rooted, flashed and repaired all kinds of android phones in the past years, never without problems, but I could always fix it somehow. Not so much this time.
Now I'm stuck at Bootscreen with the Zuk logo. I even have problems pinging the phone via ADB.
Sorry for my noobish question guys. Any help would be much appreciated.

I got this translated from a chinese website:
For fastboot mode:
The phone turned off; keep the connection turned off the data cable to the computer, press: [volume down key] [Power Key] waiting to enter the fastboot mode.
For recovery:
Turn off the device
Press and hold Power key
When vibrates Volume UP key + Volume Down key about 10 seconds
Release all key when Android logo appear then you will see Android System Recovery
Use Volume key to select Menu
Use Power key to Confirm
Can you enter any of these 2 modes?

The bootloop is just showing the ''ZUK logo'' in the middle of screen and "'powered by Android logo'' below,and the phone vibrates everytime it flashes these logos. I tried QFIL but it can only detects the unit on the first boot or first flash that is 2 secs. only from the time i press the power button, and then it disconnects and not detect the unit again. Does anyone know where can i find the scatter file , MTK ROM for zuk z1, i would like to try the SP flasher tool. Or if anyone have any idea how to solve this issue on lenovo zuk z1,pls. help.tnx
Can y get to fastboot ?
im facing the same problem after i had the stupid idea to lock the bootloader again, before that i flashed the phone successfully with the cm mod recovery and cm 13.
Has anyone found a solution to this ? or do i have to send it back ?
What i did exactly :
I locked the bootloader again and just to test it i tried flashing the recovery again , ofcourse it didn't work which was what i wanted.
Afterwards i rebootet the bootloader with sudo fastboot -i 0x2b4c reboot
now im stuck in a bootloop that i cant even stop , in other words i cant turn my phone off nor can i access the recovery or fastboot
Im feeling so stupid that i locked it again .... i will try to get into recovery after my phone ran out of battery but so far it looks quite bad...does anyone know if i will get a replacement even though it was my fault ? ( i don't need to say that it was my fault ..and the bootloader is now locked again )
UPDATE::
I found a promising thread about this problem, i will report back here if i was successful.

Please help , same problem
I am facing same issue too from 2 days. I didnt even try to flash custom roms or play with boot loader or recovery or anything. All of a sudden my phone entered boot loop. After two three bootloops phone is entering "12 apps optimized of 230 apps" mode, completing optimizing all apps and then failing to start apps, entering boot loop again.
Effort made so far to fix -
1) Went to recovery and cleared cache - didnt work
2) Went to recovery and did factory reset - factory reset did happen but boot loop didnt stop, I realized that factory reset happened because now its saying optimizing 120 apps instead of my 230 apps during the bootloop.
3) Went to recovery, Entered fast boot mode but not able to connect to PC. Fastboot devices is not showing anything. I made sure proper driver is installed after researching on XDA.
4) Went to recovery, Tried "Install update". Didnt install anything but browsed through folder structure and realized my data is intact
It will be great if someone can help me atleast recover my data before I handover phone to service center for fixing boot loop issue.
Same problem

Sorry For Re-posting Here. This is Solution
Why this is happening ?
Due to Dirty Flash from Zui or from COS/CMOD but suddenly Bootloader gets locked
May be Due to Some Custom Rom which only works with Old Bootloader ( And you are on latest 2.5 Zui QPST Flash)
Reasons are many. I also did same mistake. I flashed ZUI 2.5 using QPST then unlock bootloader using official site installed twrp after wiping cache system and data , Installed Lineage 0S JAN Build then without rebooting installed Lineage Nightly build (Latest) with Gapps After rebooting Phone goes into Restart endless loop on ZUK Logo. Blink and Vibrate .. After 1hr I figured it out but its 5am So slept.
HOW TO FIX ENDLESS REBOOT ON ZUK Logo ?
-> Identity vibrate patterns (Press Power Key I count 6- 7 Vibration pattern ) After long Vibrate immediately remove finger from power key.
->Once its Done (Phone completely off)
Download QPST and Official COS QPST from this Link https://goo.gl/InWQji OR https://goo.gl/iqrnlI (I am personally Very Thankful to D tech Terminal for posting Wonderful video on Youtube https://www.youtube.com/watch?v=4Dl6JkAVpuM
<- please install all drivers and software.->) @ankurpandeyvns Thanks bro.
Main Task is here and Lots of Patience is required and You also need to be very Blazing fast to achieve this.
-Once you download and install Qpst open Qfil
-Now press Volume Up only and connect USB (Just press POWER KEY only for 1 sec It will vibrate and connect)
-Without waiting hit Download button.
-Voila It will start flashing your phone again and Hence Your phone is now Revive..
-Once Revive You can use it to again flash custom Rom or stick to stock Rom if you want.
Keep Flashing !!!
Patience is Key here. And Don't lose hope.
:good:
EDITED:
While connecting to pc and by pressing Volume key you also need to press Power key for 1 sec or 2 sec until it gets detected. Thanks addicted777 (for tip)
